Prospectus

The Securities and Exchange Commission has not approved or disapproved of these securities or passed on the accuracy or adequacy of this Prospectus. Any representation to the contrary is a criminal offense.

This Prospectus describes Janus Henderson Transformational Growth ETF (the “Fund”), a portfolio of Janus Detroit Street Trust (the “Trust”). Janus Henderson Investors US LLC (the “Adviser”) serves as investment adviser to the Fund.

Shares of the Fund are not individually redeemable and the owners of Fund shares may purchase or redeem shares from the Fund in Creation Units only, in accordance with the terms set forth in this Prospectus. The purchase and sale price of individual Fund shares trading on an exchange may be below, at or above the most recently calculated net asset value for Fund shares (sometimes referred to as the “NAV”).

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

5 | Janus Henderson Transformational Growth ETF

Investment Adviser: Janus Henderson Investors US LLC

Portfolio Management: Brian Recht is Co-Portfolio Manager of the Fund, which he has co-managed since inception in February 2025. Nick Schommer, CFA, is Co-Portfolio Manager of the Fund, which he has co-managed since inception in February 2025.

The Fund is an actively-managed exchange-traded fund (“ETF”). Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called “Creation Units” through APs. The Adviser may modify the Creation Unit size with prior notification to the Fund’s APs. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund’s NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.

Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions, and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”). Historical information regarding the Fund’s bid/ask spread can be accessed on Janus Henderson’s website at janushenderson.com/performance and then selecting the Fund.

The Fund’s distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Additional Information about the Fund

The Fund’s Board of Trustees (the “Trustees”) may change the Fund’s investment objective or non-fundamental principal investment strategies without a shareholder vote. The Fund will notify you in writing at least 60 days or as soon as reasonably practicable before making any such change it considers material. If there is a material change to the Fund’s investment objective or principal investment strategies, you should consider whether the Fund remains an appropriate investment for you. There is no guarantee that the Fund will achieve its investment objective.

On each business day before commencement of trading in shares on the Exchange, the Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV per share. A description of the Fund’s policies and procedures with respect to the disclosure of the Fund’s portfolio holdings is available in the Fund’s Statement of Additional Information (“SAI”). Information about the premiums and discounts at which the Fund’s shares have traded is available at janushenderson.com/performance by selecting the Fund for additional details.

The following additional investment strategies and general policies apply to the Fund and provide further information including, but not limited to, the types of securities the Fund may invest in when implementing its investment objective. Some of these strategies and policies may be part of a principal strategy. Other strategies and policies may be utilized to a lesser extent as a complement to the Fund’s principal strategy. Except for the Fund’s policies with respect to investments in illiquid investments, borrowing and derivatives use, the percentage limitations included in these policies and elsewhere in this Prospectus and/or the SAI normally apply only at the time of purchase of a security. So, for example, if the Fund exceeds a limit, other than illiquid investments, borrowing and derivatives use, as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities. Also see the Fund’s SAI for supplemental information on other investments which the Fund may invest and other investment techniques in which the Fund may engage from time to time and related risk of those activities.

The Fund may borrow to the extent permitted by the 1940 Act. For temporary liquidity and cash management purposes, the Fund may invest in other ETFs that provide exposure to related securities.

Security Selection

The Fund pursues its investment objective by normally investing in a portfolio of 20-30 equity securities. In selecting investments, portfolio managers employ a combination of a “bottom up” fundamental security selection with a “top down” thematic approach, focusing on secular themes transforming society. In applying a “bottom up” approach that focuses on fundamental research, portfolio management considers, among other factors, a company’s sustainable competitive advantages, long-term growth potential, and shareholder value. In applying a “top down” thematic approach, portfolio management seeks to construct an overall portfolio with characteristics tied to secular themes transforming society. The Fund will generally consider selling a security when, in portfolio management’s opinion, there is a deterioration in a company’s financials, the investment thesis for owning the position has changed, or if the security trades at intrinsic value.

Cash Position

The Fund may not always stay fully invested. When portfolio management believes that market conditions are unfavorable for investing, or when portfolio management is otherwise unable to locate attractive investment opportunities, the Fund’s cash or similar investments may increase. When the Fund’s investments in cash or similar investments increase, it may not participate in market advances or declines to the same extent that it would if the Fund remained more fully invested. To the extent the Fund invests its uninvested cash through a sweep program (meaning its uninvested cash is pooled with uninvested cash of other funds and invested in certain securities such as repurchase agreements), it is subject to the risks of the account or fund into which it is investing, including liquidity issues that may delay the Fund from accessing its cash.

In addition, the Fund may temporarily increase its cash position under certain unusual circumstances, such as to protect its assets or maintain liquidity in certain circumstances to meet unusually large redemptions. The Fund’s cash position may also increase temporarily due to unusually large cash inflows. Under extraordinary circumstances such as these, the Fund may invest up to 100% of its assets in cash or similar investments. In this case, the Fund may take positions that are inconsistent with its investment policies. As a result, the Fund may not achieve its investment objective.

7 | Janus Detroit Street Trust

Depositary Receipts

The Fund may invest in sponsored and unsponsored American Depositary Receipts (“ADRs”), which are receipts issued by an American bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. ADRs, in registered form, are designed for use in U.S. securities markets. Unsponsored ADRs may be created without the participation of the foreign issuer. Holders of these ADRs generally bear all the costs of the ADR facility, whereas foreign issuers typically bear certain costs in a sponsored ADR. The bank or trust company depositary of an unsponsored ADR may be under no obligation to distribute shareholder communications received from the foreign issuer or to pass through voting rights. The Fund may invest in American Depositary Shares (“ADSs”), which are U.S. dollar-denominated equity shares of a foreign-based company available for purchase on an American stock exchange. ADSs are issued by depository banks in the United States under an agreement with the foreign issuer, and the entire issuance is called an ADR and the individual shares are referred to as ADSs.

Emerging Markets

Within the parameters of its specific investment policies, the Fund may invest in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries consist of countries included in either the MSCI Emerging Markets Index, and/or the International Monetary Fund’s list of Emerging and Developing Economies. Emerging market countries in which the Fund may invest include frontier market countries, the economies of which are less developed than other emerging market countries. Frontier market countries typically are located in the Asia-Pacific region, Central and Eastern Europe, the Middle East, Central and South America, and Africa.

Exchange-Traded Funds

The Fund may invest in ETFs, including affiliated ETFs. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of the Fund, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in the underlying ETFs and may be higher than other ETFs or mutual funds that invest directly in stocks and bonds. Since ETFs are traded on an exchange at market prices that may vary from the NAV of their underlying investments, there may be times when ETFs trade at a premium or discount. In the case of affiliated ETFs, unless waived, the Adviser will earn fees both from the Fund and from the underlying ETF, with respect to assets of the Fund invested in the underlying ETF.

Foreign Securities

The Fund may invest in foreign securities. Portfolio management seeks investments that meet the selection criteria, regardless of where an issuer or company is located, within the parameters of the Fund’s investment policies. Foreign securities, which are investments in securities of issuers or companies that are economically tied to different countries outside of the United States, are generally selected on a security- by-security basis without regard to any predetermined allocation among countries or geographic regions. However, certain factors, such as expected levels of inflation, government policies influencing business conditions, the outlook for currency relationships, and prospects for economic growth among countries, regions, or geographic areas, may warrant greater consideration in selecting foreign securities. An issuer is deemed to be economically tied to a country or countries if one or more of the following tests are met: (i) the issuer is organized in, or its primary business office or principal trading market of its equity is located in, the country; (ii) a majority of the issuer’s revenues are derived from one or more countries; or (iii) a majority of the issuer’s assets are located in one or more countries. The Fund may at times have significant foreign exposure, including exposure to emerging markets.

Illiquid Investments

The Fund will not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. An illiquid investment is any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.

Nondiversification

Diversification is a way to reduce risk by investing in a broad range of stocks or other securities. The Fund is classified as nondiversified. A fund that is classified as nondiversified has the ability to take larger positions in securities than a fund that is classified as diversified. This gives a fund which is classified as nondiversified more flexibility to focus its investments in companies that portfolio management has identified as attractive opportunities in pursuing the investment objective and

8 | Janus Detroit Street Trust

strategy of the fund. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of a fund.

Portfolio Turnover

Portfolio turnover rates are generally not a factor in making buy and sell decisions on behalf of the Fund. Changes may be made to the Fund’s portfolio, consistent with the Fund’s investment objective and policies, when portfolio management believes such changes are in the best interests of the Fund and its shareholders. Short-term transactions may result from the purchase of a security in anticipation of relatively short-term gains, liquidity needs, securities having reached a price or yield objective, changes in interest rates or the credit standing of an issuer, or by reason of economic or other developments not foreseen at the time of the initial investment decision. The Fund may also sell one security and simultaneously purchase the same or a comparable security to take advantage of short-term differentials in bond yields or securities prices. Portfolio turnover is affected by market conditions, changes in the size of the Fund (including due to purchases and redemptions of Creation Units), the nature of the Fund’s investments, and the investment style of portfolio management.

Increased portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover also may have a negative effect on the Fund’s performance. The “Financial Highlights” section of this Prospectus shows the Fund’s historical turnover rates.

Securities Lending

The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination. When the Fund lends its securities, it receives collateral (including cash collateral), at least equal to the value of securities loaned. The Fund may earn income by investing this collateral in one or more affiliated or non-affiliated cash management vehicles or in time deposits. The Adviser intends to manage a portion of the cash collateral in an affiliated cash management vehicle and will receive an investment advisory fee for managing such assets.

Special Situations

The Fund may invest in companies that demonstrate special situations or turnarounds, meaning companies that have experienced significant business problems but are believed to have favorable prospects for recovery. For example, a special situation or turnaround may arise when, in the opinion of the Fund’s portfolio management, the securities of a particular issuer will be recognized as undervalued by the market and appreciate in value due to a specific development with respect to that issuer. Special situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a redirection of free cash flow. For example, issuers undergoing significant capital changes may include companies involved in spin-offs, sales of divisions, mergers or acquisitions, companies involved in bankruptcy proceedings, or companies initiating large changes in their debt to equity ratio. Companies that are redirecting cash flows may be reducing debt, repurchasing shares, or paying dividends. Special situations may also result from: (i) significant changes in industry structure through regulatory developments or shifts in competition; (ii) a new or improved product, service, operation, or technological advance; (iii) changes in senior management or other extraordinary corporate event; (iv) differences in market supply of and demand for the security; or (v) significant changes in cost structure.

Other Types of Investments

Unless otherwise stated within its specific investment policies, the Fund may also invest in other types of domestic and foreign securities and use other investment strategies. These securities and strategies are not intended to be principal investment strategies of the Fund. If successful, they may benefit the Fund by earning a return on the Fund’s assets or reducing risk; however, they may not achieve the Fund’s investment objectives.

The value of your investment will vary over time, sometimes significantly, and you may lose money by investing in the Fund. The following information is intended to help you better understand some of the risks of investing in the Fund, including the principal risks that are summarized in the Fund Summary section. This information also includes descriptions of other risks the Fund may be subject to as a result of additional investment strategies and general policies that may apply to the

9 | Janus Detroit Street Trust

Fund. The impact of the following risks on the Fund may vary depending on the Fund’s investments. The greater the Fund’s investment in a particular security, the greater the Fund’s exposure to the risks associated with that security. Before investing in the Fund, you should consider carefully the risks that you assume when investing in the Fund.

Affiliated Underlying Fund Risk. The Adviser may invest in certain affiliated funds as investments for the Fund. The Adviser will generally receive fees for managing such funds, in addition to the fees paid to the Adviser by the Fund. The payment of such fees by affiliated funds creates a conflict of interest when selecting affiliated funds for investment in the Fund. The Adviser, however, is a fiduciary to the Fund and its shareholders and is legally obligated to act in its best interest when selecting affiliated funds. In addition, the Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any of the affiliated funds with respect to the Fund’s investment in such fund, less certain operating expenses.

Depositary Receipts Risk. Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, market risk, and foreign exposure risk, because their values depend on the performance of a foreign security denominated in its home currency.

Emerging Markets Risk. The Fund invests in securities of issuers or companies from or with exposure to one or more “developing countries” or “emerging market countries.” Such countries consist of countries included in either the MSCI Emerging Markets Index, and/or the International Monetary Fund list of Emerging and Developing Economies. The risks of foreign investing are heightened when investing in emerging markets, which may result in the price of investments in emerging markets experiencing sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of stock exchanges, brokers, and listed companies than in more developed markets, making these investments potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments.

The securities markets of many of these emerging market countries may also be smaller, less liquid, and subject to greater price volatility than those in the United States. In the event of a default on any investments in foreign debt obligations, it may be more difficult for the Fund to obtain or to enforce a judgment against the issuers of such securities. In addition, the Fund’s investments may be denominated in foreign currencies and therefore, changes in the value of a country’s currency compared to the U.S. dollar may affect the value of the Fund’s investments. The Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets.

Equity Securities Risk. The values of equity securities may decline due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. They may also decline due to factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry. Equity securities generally have greater price volatility than fixed-income securities. These risks are generally magnified in the case of equity investments in distressed companies.

Exchange-Traded Funds Risk. ETFs are traded on a national securities exchange at market prices that may vary from the NAV of their underlying investments. Accordingly, there may be times when an ETF trades at a premium or discount to its NAV. When the Fund invests in an ETF, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in the underlying ETF. ETFs also involve the risk that an active trading market for an ETF’s shares may not develop or be maintained. Similarly, because the value of ETF shares depends on the demand in the market, the Fund may not be able to purchase or sell an ETF at the most optimal time, which could adversely affect the Fund’s performance. In addition, ETFs that track particular indices may be unable to match the performance of such underlying indices due to the temporary unavailability of certain index securities in the secondary market or other factors, such as discrepancies with respect to the weighting of securities. The ETFs in which the Fund may invest are subject to specific risks, depending on the investment strategy of the ETF. In turn, the Fund will be subject to substantially the same risks as those associated with direct exposure to the securities or commodities held by the ETF. Because the Fund may invest in a broad range of ETFs, such risks may include, but are not limited to, leverage risk, foreign exposure risk, and commodity-linked investments risk.

10 | Janus Detroit Street Trust

Foreign Exposure Risk. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because the performance of the Fund’s foreign securities holdings may depend on structural or macroeconomic factors in addition to the performance of a particular company. These factors include:

Geographic Concentration Risk. To the extent that the Fund invests a substantial amount of its assets in issuers located in a single country or region, the economic, political, social, regulatory, or other developments or conditions within such country or region will generally have a greater effect on the Fund than they would on a more geographically diversified fund, which may result in greater losses and volatility. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance.

Growth Securities Risk. Growth securities are those issued by companies whose earnings growth potential appears to be greater than the market in general and whose revenue growth is expected to continue for an extended period of time. Growth securities may trade at higher multiples of current earnings compared to value or other stocks, leading to inflated prices and thus potentially greater declines in market value. The prices of growth securities may be more volatile than those of other types of investments and can decline rapidly and significantly in reaction to negative news. Growth securities may underperform value securities and other types of assets as well as the overall stock market. Under certain market conditions, growth securities

11 | Janus Detroit Street Trust

have performed better during the later stages of economic recovery, although there is no assurance that they will continue to do so. Growth securities typically do not pay a dividend, which can help cushion stock prices in market downturns and reduce potential losses. Growth securities may go in and out of favor over time, which could affect the performance of the Fund.

Industry and Sector Risk. Industry and sector risk is the possibility that a group of related securities will decline in price due to industry-specific or economic sector-specific developments. Companies in the same or similar industries and economic sectors may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. The Fund’s investments in companies in a particular industry or economic sector may increase the Fund’s exposure to industry and sector risk. As the Fund’s portfolio becomes more concentrated, the Fund is less able to spread risk and potentially reduce the risk of loss and volatility.

Issuer Concentration Risk. The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments.

Liquidity Risk. Portfolio management may invest in securities or instruments that do not trade actively or in large volumes, and may make investments that are relatively less liquid or illiquid. Also, portfolio management may make investments that may become less liquid in response to market developments or adverse investor perceptions. Investments that are illiquid or that trade in lower volumes may be more difficult to value. When there is no willing buyer and investments cannot be readily sold at the desired time or price, portfolio management may have to accept a lower price or may not be able to sell the security or instrument at all. Investments in foreign securities, particularly those of issuers located in emerging market countries, tend to have greater exposure to liquidity risk than domestic securities. In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk (i.e., if the number and capacity of traditional market participants is reduced). An inability to sell one or more portfolio positions can adversely affect the Fund’s value or prevent portfolio management from being able to take advantage of other investment opportunities. Liquidity risk may be increased to the extent that portfolio management invests in other securities exempt from certain registration requirements that are deemed to be illiquid investments.

Market Capitalization Risk. To the extent the Fund focuses its investments in small-, mid-, or large-sized companies, it may be subject to associated risks. At any given time, any of these market capitalizations may go in and out of favor based on market and economic conditions.

12 | Janus Detroit Street Trust

Market Risk. The value of the Fund’s portfolio may decrease if the value of one or more issuers in the Fund’s portfolio decreases. Further, regardless of how well individual companies or securities perform, the value of the Fund’s portfolio could also decrease if there are deteriorating economic or market conditions, including, but not limited to, a general decline in prices on the stock markets, a general decline in real estate markets, a decline in commodities prices, or if the market favors different types of securities than the types of securities in which the Fund invests. If the value of the Fund’s portfolio decreases, the Fund’s NAV will also decrease, which means if you sell your shares in the Fund, you may lose money. Market risk may affect a single issuer, industry, economic sector, or the market as a whole.

The increasing interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Social, political, economic and other conditions and events, such as natural disasters, health emergencies (e.g., epidemics and pandemics), terrorism, war, armed conflicts, including related sanctions, social unrest, tariffs, trade disputes, financial institution failures, and economic recessions could reduce consumer demand or economic output, result in market closures, travel restrictions and/or quarantines, and generally have a significant and negative impact on the global economies and financial markets.

Money Market Fund Investment Risk. The Fund may have cash balances that have not been invested in portfolio securities, which may be used to purchase shares of affiliated or non-affiliated money market funds, or cash management pooled investment vehicles that operate as money market funds, as part of a cash sweep program. By investing in a money market fund, the Fund will be exposed to the investment risks of the money market fund in direct proportion to such investment. The money market fund may not achieve its investment objective and the Fund may lose money. To the extent the Fund transacts in instruments such as derivatives, the Fund may hold investments, which may be significant, in money market fund shares to cover its obligations resulting from the Fund’s investments in derivatives. An investment in a money market fund is not a bank deposit and is not insured or guaranteed by any bank, the Federal Deposit Insurance Corporation or any other government agency. There can be no assurance that a money market fund will maintain a $1.00 per share NAV at all times. Factors that could adversely affect the value of a money market fund’s shares include, among other things, a sharp rise in interest rates, an illiquid market for the securities held by the money market fund, a high volume of redemption activity in a fund’s shares, and a credit event or credit rating downgrade affecting one or more of the issuers of securities held by the money market fund. In addition, the failure of even an unrelated money market fund to maintain a stable NAV could create a widespread risk of increased redemption pressures on all money market funds, potentially jeopardizing the stability of their NAVs. Certain money market funds have in the past failed to maintain stable NAVs, and there can be no assurance that such failures and resulting redemption pressures will not impact money market funds in the future.

Rules adopted by the U.S. Securities and Exchange Commission (the “SEC”) require, among other things, certain money market funds to cause transactions in shares of these funds to be effected using a fund’s NAV per share calculated out to the fourth decimal point (e.g., $1.0000 instead of $1.00). “Government Money Market Funds” and “Retail Money Market Funds” as defined in Rule 2a-7 under the 1940 Act, as amended, are not subject to the floating NAV requirements, as described above. In addition, certain money market funds may impose a discretionary fee (up to 2%) upon sale of shares because of market conditions or other factors if a fund’s board or a delegate believes such fee is in the best interest of the fund. There can be no assurance that the Fund’s investments in money market funds are not adversely affected by reforms to money market regulation that may be adopted by the SEC or other regulatory authorities.

13 | Janus Detroit Street Trust

In addition to the fees and expenses that the Fund directly bears, the Fund indirectly bears the fees and expenses of any money market fund in which it invests.

New/Smaller Sized Fund Risk. Because the Fund is relatively new, it has a limited operating history and a small asset base. The Fund’s performance may not represent how the Fund is expected to or may perform in the long term if and when it becomes larger. If a new or smaller fund were to fail to attract sufficient assets to achieve or maintain economies of scale, performance may be negatively impacted, and any resulting liquidation could create negative transaction costs for the Fund and tax consequences for investors.

Nondiversification Risk. The Fund is classified as nondiversified under the 1940 Act, and therefore may hold a greater percentage of their assets in a smaller number of securities. As a result, an increase or decrease in the value of a single security held by the Fund may have a greater impact on the Fund’s NAV and total return. Being nondiversified may also make the Fund more susceptible to financial, economic, political, or other developments that may impact a security. Although the Fund may satisfy the requirements for a diversified fund from time to time, the Fund’s nondiversified classification gives the Fund’s portfolio management more flexibility to hold larger positions in securities than a fund that is classified as diversified.

Operational Risk. An investment in the Fund can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in key personnel, technology and/or service providers, and errors caused by third party service providers. Among other things, these errors or failures, as well as other technological issues, may adversely affect the Fund’s ability to calculate its NAV, process fund orders, execute portfolio trades, or perform other essential tasks in a timely manner, including over a potentially extended period of time. These errors or failures may also result in a loss or compromise of information, regulatory scrutiny, reputational damage or other events, any of which could have a material adverse effect on the Fund. Implementation of business continuity plans by the Fund, the Adviser or third-party service providers in response to disruptive events such as cyber attacks on critical infrastructure, natural disasters, epidemics and pandemics, terrorism, conflicts and social unrest may increase these operational risks to the Fund. While the Fund seeks to minimize such events through internal controls and oversight of third-party service providers, there is no guarantee that the Fund will not suffer losses if such events occur.

Portfolio Management Risk. The Fund is an actively managed investment portfolio and is therefore subject to the risk that the investment strategies and research process employed for the Fund may fail to achieve its investment objective or produce the intended results. Although the Fund seeks to provide long-term positive returns, market conditions or implementation of the Fund’s investment process may result in losses, and the Fund may not meet its investment objective. As such, there can be no assurance of positive “absolute” return. The Fund may underperform benchmark indices or other funds with similar investment objectives.

Secondary Market Trading Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s securities holdings. However, the Fund’s shares may trade on a national securities exchange at prices above or below their most recent NAV. The “market price” for a share of the Fund fluctuates continuously throughout the national securities exchange’s trading day and is based on supply and demand for the Fund’s shares. The market price of the Fund’s shares may not track the Fund’s NAV, which is only calculated at the end of each business day.

A potential investor in the Fund will likely also incur the cost of the “spread” (the difference between the bid price and the ask price for a share of the Fund). The spread varies over time for a share of the Fund. This cost is generally smaller for a fund with significant daily trading volumes and larger for funds with smaller daily trading volumes.

Additionally, during a “flash crash,” the market price of the Fund’s shares may decline suddenly and significantly, resulting in the Fund’s shares trading at a substantial discount to its net asset value. Such a decline may not reflect the performance of the Fund’s securities holdings. Flash crashes may also cause APs and other market makers to limit or cease trading in Fund shares, which may result in a further increase in the variance between market prices of the Fund’s shares and their net asset value. Shareholders could suffer significant losses to the extent that they sell Fund shares during a flash crash.

Securities Lending Risk. Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund lends its securities and is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market which may subject the Fund to additional costs. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to the Fund. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Any cash received as collateral for loaned securities will be invested in an affiliated cash management vehicle or time deposits. This investment is subject to market appreciation or depreciation and the Fund will bear any loss on the investment of its cash collateral. It is possible that, due to a decline in the value of a cash management vehicle in which collateral is invested, the Fund may lose money.

Management of the Fund

Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805, is the investment adviser to the Fund. The Adviser is responsible for the day-to-day management of the Fund’s investment portfolio and furnishes continuous advice and recommendations concerning the Fund’s investments. The Adviser also provides certain administration and other services and is responsible for other business affairs of the Fund.

The Adviser (together with its predecessors and affiliates) has served as investment adviser to Janus Henderson mutual funds since 1970 and currently serves as investment adviser to all of the Janus Henderson funds, the Janus Henderson exchange-traded funds, acts as subadviser for a number of private-label mutual funds, and provides separate account advisory services for institutional accounts and other unregistered products.

On December 22, 2025, Janus Henderson Group plc (“Janus Henderson”), the parent company of the Adviser to the Fund, Trian Fund Management, L.P. and its affiliated funds (“Trian”), and General Catalyst Group Management, LLC and its affiliated funds (“General Catalyst”) announced that they have entered into a definitive agreement under which Janus Henderson will be acquired by Trian and General Catalyst (the “Transaction”). The Transaction is expected to close in 2026, subject to customary closing conditions, including requisite regulatory approvals, client consents, and approval by Janus Henderson’s shareholders.

The closing of the Transaction will be deemed to be an “assignment” (as defined in the Investment Company Act of 1940, as amended) of the advisory agreement between the Fund and the Adviser. As a result, the closing of the Transaction will cause the advisory agreement to terminate automatically in accordance with its terms. On February 11, 2026, the Trustees approved a new advisory agreement with the Adviser. The new agreement will be presented to the Fund’s shareholders for approval, and, if so approved by shareholders, will take effect upon the closing of the Transaction or such later time as shareholder approval is obtained.

The Trust and the Adviser have received an exemptive order from the U.S. Securities and Exchange Commission (the “SEC”) that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the 1940 Act) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).

Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and, as appropriate, reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight by the Trustees, would have the responsibility to oversee such subadviser(s) to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. In the event that the Adviser hires a subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.

The Trustees and the initial shareholder of the Fund have approved the use of a manager-of-managers structure for the Fund.

The Fund uses a unitary fee structure, under which the Fund pays the Adviser a “Management Fee” in return for providing certain investment advisory, supervisory, and administrative services to the Fund, including the costs of transfer agency, custody, fund administration, legal, audit, and other services. The Adviser’s fee structure is designed to pay substantially all of the Fund’s expenses. However, the Fund bears other expenses which are not covered under the Management Fee which

15 | Janus Detroit Street Trust

may vary and affect the total level of expenses paid by shareholders, such as distribution fees (if any), brokerage expenses or commissions, interest and dividends (including those relating to short positions (if any)), taxes, litigation expenses, acquired fund fees and expenses (if any), and extraordinary expenses.

The Fund’s Management Fee is calculated daily and paid monthly. The Fund’s advisory agreement details the Management Fee and other expenses that the Fund must pay.

The following table reflects the Fund’s contractual Management Fee rate (expressed as an annual rate), as well as the actual compensation rate paid to the Adviser after any applicable fee waivers and/or expense reimbursements for the most recent fiscal year. The rates shown are fixed rates based on the Fund’s daily net assets.

A discussion regarding the basis for the Trustees’ approval of the Fund’s investment advisory agreement is included in the Fund’s financial statements located in Form N-CSR for the period ending April 30, 2025). This information is available, free of charge, at janushenderson.com/info, under “Financial Statements and Other Information,” or by contacting a Janus Henderson representative at 1-800-668-0434. You may also request this information, free of charge, by contacting your plan sponsor, broker-dealer, or financial intermediary.

Expense Limitation

The Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of Fund assets invested in the affiliated ETF, multiplied by an amount equal to the current daily unitary management fee of the affiliated ETF less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETF (including, but not limited to custody, sub-administration and transfer agency fees, and fees paid to the distributor). The fee waiver agreement will remain in effect at least until February 28, 2028. The Adviser will not recover amounts previously waived or reimbursed that are related to investments in affiliated ETFs. The fee waiver agreement may be modified or terminated prior to this date only at the discretion of the Trustees.

Janus Henderson Transformational Growth ETF

Co-Portfolio Managers Brian Recht and Nick Schommer jointly are responsible for the day-to-day management of the Fund, with no limitation on the authority of one co-portfolio manager in relation to the other.

Brian Recht is Co-Portfolio Manager of Janus Henderson Transformational Growth ETF, which he has co-managed since inception in February 2025. Mr. Recht is also Portfolio Manager of other Janus Henderson accounts and performs duties as an analyst. He joined the Adviser in 2015 as a research analyst. Mr. Recht holds a Bachelor of Arts degree (summa cum laude) in Government from Dartmouth College where he was a member of Phi Beta Kappa. He also holds a Master of Business Administration degree from the Stanford Graduate School of Business and a Juris Doctorate from Stanford Law School.

Nick Schommer, CFA, is Co-Portfolio Manager of Janus Henderson Transformational Growth ETF, which he has co-managed since inception in February 2025. Mr. Schommer is also Portfolio Manager of other Janus Henderson accounts. He joined the Adviser in 2013. He holds a Bachelor of Science degree in Chemistry from the U.S. Military

16 | Janus Detroit Street Trust

Academy at West Point, where he was recognized as a Distinguished Cadet and Phi Kappa Phi, and a Master of Business Administration degree from the UCLA Anderson School of Management. Mr. Schommer holds the Chartered Financial Analyst designation.

Information about portfolio management’s compensation structure and other accounts managed, as well as the aggregate range of their individual ownership in the Fund, is included in the SAI.

Conflicts of Interest

The Adviser manages other funds and numerous other accounts, which may include separate accounts and other pooled investment vehicles, such as hedge funds. Side-by-side management of multiple accounts, including the management of a cash collateral pool for securities lending and investing the Janus Henderson funds’ cash, may give rise to conflicts of interest among those accounts, and may create potential risks, such as the risk that investment activity in one account may adversely affect another account. For example, short sale activity in an account could adversely affect the market value of long positions in one or more other accounts (and vice versa). Side-by-side management may raise additional potential conflicts of interest relating to the allocation of investment opportunities and the aggregation and allocation of trades.

In addition, from time to time, the Adviser or its affiliates may, subject to compliance with applicable law, purchase and hold shares of the Fund for their own accounts, or may purchase shares of the Fund for the benefit of their clients, including other Janus Henderson funds. Increasing the Fund’s assets may enhance the Fund’s profile with financial intermediaries and platforms, investment flexibility and trading volume. The Adviser and its affiliates reserve the right, subject to compliance with applicable law, to dispose of at any time some or all of the shares of the Fund acquired for their own accounts or for the benefit of their clients. A large sale of Fund shares by the Adviser or its affiliates could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility or trading volume. The Adviser considers the effect of redemptions on the Fund and other shareholders in deciding whether to dispose of its shares of the Fund.

The Adviser believes it has appropriately designed and implemented policies and procedures to mitigate these and other potential conflicts of interest. A further discussion of potential conflicts of interest and policies and procedures intended to mitigate them is contained in the Fund’s SAI.

Other Information

Creation Units for the Fund are distributed by ALPS Distributors, Inc. (the “Distributor”), which is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”). To obtain information about FINRA member firms and their associated persons, you may contact FINRA at www.finra.org, or 1-800-289-9999.

Dividends, Distributions and Taxes

To avoid taxation of the Fund, the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), requires the Fund to distribute all or substantially all of its net investment income and any net capital gains realized on its investments at least annually.

Distribution Schedule

Dividends from net investment income are generally declared and distributed to shareholders quarterly. Distributions of net capital gains are declared and distributed at least annually. Dividends may be declared and paid more frequently to comply with the distribution requirements of the Internal Revenue Code. The date you receive your distribution may vary depending on how your intermediary processes trades. Dividend payments are made through Depository Trust Company (“DTC”) participants and indirect participants to beneficial owners then of record with proceeds received from the Fund. Please consult your financial intermediary for details.

How Distributions Affect the Fund’s NAV

Distributions are paid to shareholders as of the record date of a distribution of the Fund, regardless of how long the shares have been held. Undistributed income and net capital gains are included in the Fund’s daily NAV. The Fund’s NAV drops by the amount of the distribution, net of any subsequent market fluctuations. For example, assume that on December 31, the Fund declared a dividend in the amount of $0.25 per share. If the Fund’s NAV was $10.00 on December 30, the Fund’s NAV on December 31 would be $9.75, barring market fluctuations. You should be aware that distributions from a taxable fund do not increase the value of your investment and may create income tax obligations.

No dividend reinvestment service is provided by the Trust. Financial intermediaries may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of Fund shares for reinvestment of their dividend distributions. Beneficial owners should contact their financial intermediary to determine the availability and costs of the service and the details of participation therein. Financial intermediaries may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and net capital gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

As with any investment, you should consider the tax consequences of investing in the Fund. The following is a general discussion of certain federal income tax consequences of investing in the Fund. The discussion does not apply to qualified tax-advantaged accounts or other non-taxable entities, nor is it a complete analysis of the federal income tax implications of investing in the Fund. You should consult your tax adviser regarding the effect that an investment in the Fund may have on your particular tax situation, including the federal, state, local, and foreign tax consequences of your investment.

Taxes on Distributions

Distributions by the Fund are subject to federal income tax, regardless of whether the distribution is made in cash or reinvested in additional shares of the Fund. Distributions from net investment income (which includes dividends, interest, and realized net short-term capital gains), other than qualified dividend income, are taxable to shareholders as ordinary income. Distributions of qualified dividend income are taxed to individuals and other noncorporate shareholders at long- term capital gain rates, provided certain holding period and other requirements are satisfied. Dividends received from real estate investment trusts (“REITs”), certain foreign corporations, and income received “in lieu of” dividends in a securities lending transaction generally will not constitute qualified dividend income.

Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gain, regardless of how long a shareholder has held Fund shares. Individuals, trusts, and estates whose income exceeds certain threshold amounts are subject to an additional 3.8% Medicare contribution tax on net investment income. Net investment income includes dividends paid by the Fund and capital gains from any sale or exchange of Fund shares. The Fund’s net investment income and capital gains are distributed to (and may be taxable to) those persons who are shareholders of the Fund at the record date of such payments. Although the Fund’s total net income and net realized gain are

19 | Janus Detroit Street Trust

the results of its operations, the per share amount distributed or taxable to shareholders is affected by the number of Fund shares outstanding at the record date. Distributions declared to shareholders of record in October, November, or December and paid on or before January 31 of the succeeding year will be treated for federal income tax purposes as if received by shareholders on December 31 of the year in which the distribution was declared. Generally, account tax information will be made available to shareholders on or before February 15 of each year. Information regarding distributions may also be reported to the Internal Revenue Service (“IRS”).

The Fund may derive “excess inclusion income” from certain equity interests in mortgage pooling vehicles either directly or through an investment in a U.S. REIT. Please see the Fund’s SAI for a discussion of the risks and special tax consequences to shareholders in the event the Fund realizes excess inclusion income in excess of certain threshold amounts.

For taxable years beginning after December 31, 2017, “qualified REIT dividends” (i.e., ordinary REIT dividends other than capital gain dividends and portions of REIT dividends designated as qualified dividend income) are treated as eligible for a 20% deduction by noncorporate taxpayers. The Fund may choose to pass through the special character of “qualified REIT dividends” to its shareholders, provided the Fund and the shareholder meet certain holding period requirements.

Taxes on Sales

Any time you sell the shares of the Fund in a taxable account, it is considered a taxable event. Depending on the purchase price and the sale price, you may have a gain or loss on the transaction. The gain or loss will generally be treated as a long- term capital gain or loss if you held your shares for more than one year and if not held for such period, as a short-term capital gain or loss. Any tax liabilities generated by your transactions are your responsibility.

U.S. federal income tax withholding may be required on all distributions payable to shareholders who fail to provide their correct taxpayer identification number, fail to make certain required certifications, or who have been notified by the IRS that they are subject to backup withholding. The current backup withholding rate is applied.

For shares purchased and sold from a taxable account, your financial intermediary will report cost basis information to you and to the IRS. Your financial intermediary will permit shareholders to elect their preferred cost basis method. In the absence of an election, your cost basis method will be your financial intermediary’s default method, which is often the average cost method. Please consult your tax adviser to determine the appropriate cost basis method for your particular tax situation and to learn more about how the cost basis reporting laws apply to you and your investments.

Taxation of the Fund

Dividends, interest, and some capital gains received by the Fund on foreign securities may be subject to foreign tax withholding or other foreign taxes.

Certain fund transactions may involve futures, options, swap agreements, hedged investments, and other similar transactions, and may be subject to special provisions of the Internal Revenue Code that, among other things, can potentially affect the character, amount, and timing of distributions to shareholders, and utilization of capital loss carryforwards. The Fund will monitor its transactions and may make certain tax elections and use certain investment strategies where applicable in order to mitigate the effect of these tax provisions, if possible.

The Fund does not expect to pay any federal income or excise taxes because it intends to meet certain requirements of the Internal Revenue Code, including the distribution each year of substantially all its net investment income and net capital gains. It is important for the Fund to meet these requirements so that any earnings on your investment will not be subject to federal income tax twice. If the Fund invests in a partnership, however, it may be subject to state tax liabilities.

If the Fund redeems Creation Units in cash, it may recognize more capital gains than it will if it redeems Creation Units in-kind.

For additional information, see the “Income Dividends, Capital Gains Distributions, and Tax Status” section of the SAI.

Shareholder’s Guide

The Fund issues or redeems its shares at NAV per share only in Creation Units. Shares of the Fund are listed for trading on a national securities exchange and trade on the secondary market during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. There is no minimum investment. When buying or selling Fund shares through a broker, you may incur brokerage commissions and charges, and you may pay some or all of the spread between the bid and offered price in the secondary market on each purchase and sale transaction. Fund shares are traded on the Exchange under the trading symbol JXX. Share prices are reported in dollars and cents per share.

APs may acquire Fund shares directly from the Fund, and APs may tender their Fund shares for redemption directly to the Fund, at NAV per share, only in Creation Units and in accordance with the procedures described in the Fund’s SAI.

The per share NAV of the Fund is computed by dividing the total value of the Fund’s portfolio, less any liabilities, by the total number of outstanding shares of the Fund. The Fund’s NAV is calculated as of the close of the trading session of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m. New York time) each day that the NYSE is open (“Business Day”). However, the NAV may still be calculated if trading on the NYSE is restricted, provided there is sufficient pricing information available for the Fund to value its securities, or as permitted by the SEC. Foreign securities held by the Fund, as applicable, may be traded on days and at times when the NYSE is closed and the NAV is therefore not calculated. Accordingly, the value of the Fund’s holdings may change on days that are not Business Days in the United States and on which you will not be able to purchase or sell the Fund’s shares.

Securities held by the Fund are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the 1940 Act and approved by and subject to the oversight of the Trustees (“Valuation Procedures”). To the extent available, equity securities (including shares of ETFs) are generally valued at readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. Most fixed-income securities are typically valued using an evaluated bid price supplied by an Adviser-approved pricing service that is intended to reflect market value. The evaluated bid price is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term instruments maturing within 60 days or less may be valued at amortized cost, which approximates market value. If a market quotation or evaluated price for a security is not readily available or is deemed unreliable, or if an event that is expected to affect the value of the security occurs after the close of the principal exchange or market on which the security is traded, and before the close of the NYSE, a fair value of the security will be determined in good faith by the Adviser pursuant to the Valuation Procedures. Such events include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a non-significant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or non-public security. This type of fair valuation may be more commonly used with foreign equity securities, but it may also be used with, among other things, thinly-traded domestic securities or fixed-income securities. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position. For valuation purposes, if applicable, quotations of foreign portfolio securities, other assets and liabilities, and forward contracts stated in foreign currency are generally translated into U.S. dollar equivalents at the prevailing market rates. The methodologies employed when fair valuing securities may change from time to time. Because fair value pricing involves subjective judgments, it is possible that the fair value determination for a security may be different than the value that could be realized when selling that security.

The value of the securities of mutual funds held by the Fund, if any, will be calculated using the NAV of such mutual funds, and the prospectuses for such mutual funds explain the circumstances under which they use fair valuation and the effects of using fair valuation. The value of the securities of any cash management pooled investment vehicles that operate as money market funds held by the Fund, if any, will be calculated using the NAV of such funds.

All purchases, sales, or other account activity must be processed through your financial intermediary or plan sponsor.

Distribution and Shareholder Servicing Plan

The Trust has adopted a Distribution and Servicing Plan for shares of the Fund pursuant to Rule 12b-1 under the 1940 Act (the “Plan”). The Plan permits compensation in connection with the distribution and marketing of Fund shares and/or the provision of certain shareholder services. The Plan permits the Fund to pay the Distributor, or its designee, a fee for the sale and distribution and/or shareholder servicing of the shares at an annual rate of up to 0.25% of average daily net assets of the shares of the Fund (“12b-1 fee”). However, payment of a 12b-1 fee has not been authorized at this time.

Under the terms of the Plan, the Trust is authorized to make payments to the Distributor or its designee for remittance to retirement plan service providers, broker-dealers, bank trust departments, financial advisors, and other financial intermediaries, as compensation for distribution and/or shareholder services performed by such entities for their customers who are investors in the Fund.

The 12b-1 fee may only be imposed or increased when the Trustees determine that it is in the best interests of shareholders to do so. Because these fees are paid out of the Fund’s assets on an ongoing basis, to the extent that a fee is authorized and payments are made, over time they will increase the cost of an investment in the Fund. The 12b-1 fee may cost an investor more than other types of sales charges.

From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries for making Janus Henderson funds available to their clients for distribution, marketing, promotional, data, or related services and/or for providing transaction processing and other shareholder or administrative services. The Adviser or its affiliates also make payments to one or more intermediaries for information about transactions and holdings in the funds, such as the amount of fund shares purchased, sold or held through the intermediary and or its salespersons, the intermediary platform(s) on which shares are transacted and other information related to the funds. Payments made by the Adviser and its affiliates may eliminate or reduce trading commissions that the intermediary would otherwise charge its customers or its salespersons in connection with the purchase or sale of certain funds. Payment by the Adviser or its affiliates to eliminate or reduce a trading commission creates an incentive for salespersons of the intermediary to sell the Janus Henderson funds over other funds for which a commission would be charged. The amount of these payments is determined from time to time by the Adviser, may be substantial, and may differ for different intermediaries. The Adviser may determine to make payments based on any number of factors or metrics. For example, the Adviser may make payments at year-end and/or other intervals in a fixed amount, an amount based upon an intermediary’s services at defined levels, an amount based upon the total assets represented by funds subject to arrangements with the intermediary, an amount based on the intermediary’s net sales of one or more funds in a year or other period, or a fee based on the management fee received by the Adviser, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. The Adviser currently maintains asset-based agreements with certain intermediaries on behalf of the Trust. The amount of compensation paid by the Adviser varies from intermediary to intermediary. More information regarding these payments is contained in the Fund’s SAI.

With respect to non-exchange-traded Janus Henderson funds not offered in this Prospectus, the Adviser or its affiliates pay fees, from their own assets, to selected brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via National Securities Clearing Corporation (“NSCC”) or other means), and the Committee on Uniform Security Identification Procedures (“CUSIP”) and fund setup fees in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for certain of these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary.

In addition, the Adviser or its affiliates may also share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, and support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Janus Henderson funds. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the

22 | Janus Detroit Street Trust

Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.

The receipt of (or prospect of receiving) payments, reimbursements and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other funds (or non-mutual fund investments), with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other funds (or non-mutual fund investments).

The payment arrangements described above will not change the price an investor pays for shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell shares of the Fund. Please contact your financial intermediary or plan sponsor for details on such arrangements.

Shares of the Fund are listed for trading on a national securities exchange during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly traded companies. However, there can be no guarantee that an active trading market will develop or be maintained, or that the Fund shares listing will continue or remain unchanged. The Fund does not impose any minimum investment for shares of the Fund purchased on an exchange. Buying or selling the Fund’s shares involves certain costs that apply to all securities transactions. When buying or selling shares of the Fund through a financial intermediary, you may incur a brokerage commission or other charges determined by your financial intermediary. Due to these brokerage costs, if any, frequent trading may detract significantly from investment returns. In addition, you may also incur the cost of the spread (the difference between the bid price and the ask price). The commission may be a significant cost for investors seeking to buy or sell small amounts of shares.

Shares of the Fund may be acquired through the Distributor or redeemed directly with the Fund only in Creation Units or multiples thereof, as discussed in the “Creation and Redemption of Creation Units” section of the Fund’s SAI. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

The Exchange is open for trading Monday through Friday and is closed on the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

A Business Day with respect to the Fund is each day the Exchange is open. Orders from APs to create or redeem Creation Units will only be accepted on a Business Day. On days when the Exchange or bond markets close earlier than normal (or on days when the bond market is closed but the Exchange is open), the Fund may require orders to create or redeem Creation Units to be placed earlier in the day. In addition, to minimize brokerage and other related trading costs associated with securities that cannot be readily transferred in-kind, the Fund may establish early trade cut-off times for APs to submit orders for Creation Units, in accordance with the 1940 Act. See the Fund’s SAI for more information.

In compliance with the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”), your financial intermediary is required to verify certain information on your account application as part of its Anti-Money Laundering Program. You will be required to provide your full name,

23 | Janus Detroit Street Trust

date of birth, social security number, and permanent street address to assist in verifying your identity. You may also be asked to provide additional documents that may help to establish your identity. Until verification of your identity is made, your financial intermediary may temporarily limit additional share purchases. In addition, your financial intermediary may close an account if it is unable to verify your identity. Please contact your financial intermediary if you need additional assistance when completing your application or additional information about your financial intermediary’s Anti-Money Laundering Program.

In an effort to ensure compliance with this law, the Adviser’s Anti-Money Laundering Program (the “Program”) provides for the development of internal practices, procedures and controls, designation of anti-money laundering compliance officers, an ongoing training program, and an independent audit function to determine the effectiveness of the Program.

Continuous Offering

The method by which Creation Units of shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of shares are issued and sold by the Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act of 1933, as amended (the “Securities Act”), may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirements and liability provisions of the Securities Act. For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells the shares directly to customers or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3)(C) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an unsold allotment within the meaning of Section 4(a)(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Book Entry

Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The DTC or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other exchange- traded securities that you hold in book-entry or “street name” form.

Premiums and Discounts

There may be differences between the daily market prices on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price per share at which the Fund issues and redeems shares. See “Pricing of Fund Shares” above. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the national securities exchange on which shares of the Fund are primarily listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above, or below its NAV. The NAV of the Fund will fluctuate with changes in the market value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand for shares of the Fund.

24 | Janus Detroit Street Trust

Premiums or discounts are the differences (expressed as a percentage) between the NAV and the Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV. A discount or premium could be significant. Information regarding the Fund’s premium/discount to NAV for the most recently completed calendar year and the most recently completed calendar quarters since that calendar year end (or the life of the Fund, if shorter) is available at janushenderson.com/performance by selecting the Fund for additional details.

Investments by Other Investment Companies

The Trust and Janus Investment Fund are part of the same “group of investment companies” for purposes of Section 12(d)(1) (G) of the 1940 Act.

Under the 1940 Act, purchases or acquisitions by the Fund of shares issued by registered investment companies (including other ETFs) and business development companies (“BDCs”) and the purchase or acquisition of Fund shares by registered investment companies, BDCs, and investment vehicles relying on Section 3(c)(1) or 3(c)(7) of the 1940 Act are subject to the restrictions set forth in Section 12(d)(1) of the 1940 Act, except where an exemption is available, including as provided in Sections 12(d)(1)(F) and (G) and Rule 12d1-4 thereunder. Rule 12d1-4 permits registered investment companies and BDCs to invest in Fund shares beyond the limits in Section 12(d)(1)(A), subject to certain terms and conditions, including that the registered investment company or BDC first enter into a written agreement with the Trust regarding the terms of the investment, among other conditions.

Unlike traditional mutual funds, the frequent trading of Fund shares generally does not disrupt portfolio management, increase the Fund’s trading costs, lead to realization of capital gains by the Fund, or otherwise harm Fund shareholders. The vast majority of trading in Fund shares occurs on the secondary market. Because these trades do not involve the Fund, they do not harm the Fund or its shareholders. APs are authorized to purchase and redeem Fund shares directly with the Fund in Creation Units. Creation Unit transactions that are effected using securities (i.e., in-kind) do not cause any of the harmful effects to the issuing fund (as previously noted). However, Creation Unit transactions effected using cash can potentially subject the Fund and its shareholders to those harmful effects. As a result, the Fund requires APs to pay transaction fees to cover brokerage and certain related costs when purchasing or redeeming Creation Units. Those fees are designed to protect the Fund and its shareholders from the dilutive costs associated with frequent creation and redemption activity. For these reasons, the Trustees of the Fund have determined that it is not necessary to adopt policies and procedures to detect and deter frequent trading and market timing of Fund shares. However, the Fund’s policies and procedures regarding frequent purchases and redemptions may be modified by the Trustees at any time.

Each Business Day, the Fund’s portfolio holdings information is provided by its custodian or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. In addition, on each Business Day before commencement of trading in shares on the Exchange, the Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV. A complete schedule of the Fund’s portfolio holdings is also available semiannually and annually in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. The Fund’s Form N-CSR and Form N-PORT filings are available on the SEC’s website at http://www.sec.gov.

For additional information on these disclosures and the availability of portfolio holdings information, please refer to the Fund’s SAI.

Statements and Reports

Your financial intermediary or plan sponsor is responsible for sending you periodic statements of all transactions, along with trade confirmations and tax reporting, as required by applicable law.

In addition, your financial intermediary or plan sponsor is also responsible for providing annual and semiannual reports. Please contact your financial intermediary or plan sponsor to obtain these reports.

You may also obtain copies of the Fund’s annual and semiannual reports, SAI and other information, such as the Fund’s financial statements (when available), free upon request by calling Janus Henderson at 1-800-668-0434 or you can access and download these documents at the Fund’s website: janushenderson.com/info.

The Fund’s fiscal year ends October 31st.

Lost (Unclaimed/Abandoned) Accounts

It is important to maintain a correct address for each shareholder. An incorrect address may cause a shareholder’s account statements and other mailings to be returned as undeliverable. Based upon statutory requirements for returned mail, your financial intermediary or plan sponsor is required to attempt to locate the shareholder or rightful owner of the account. If the financial intermediary or plan sponsor is unable to locate the shareholder, then the financial intermediary or plan sponsor is legally obligated to deem the property “unclaimed” or “abandoned,” and subsequently escheat (or transfer) unclaimed property (including shares of a fund) to the appropriate state’s unclaimed property administrator in accordance with statutory requirements. Further, your account may be deemed “unclaimed” or “abandoned,” and subsequently transferred to your state of residence if no activity (as defined by that state) occurs within your account during the time frame specified in your state’s unclaimed property laws. The shareholder’s last known address of record determines which state has jurisdiction. Interest or income is not earned on redemption or distribution check(s) sent to you during the time the check(s) remained uncashed.

Classification, Investment Policies and Restrictions,
and Investment Strategies and Risks

This Statement of Additional Information includes information about the Fund, which operates as an actively managed exchange-traded fund (“ETF”) and is a series of the Trust, an open-end, management investment company.

The Fund offers and issues shares at its net asset value (“NAV”) per share only in aggregations of a specified number of shares (“Creation Unit”), in exchange for a designated portfolio of securities, assets or other positions and/or cash (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed for trading on the Cboe BZX Exchange, Inc. (the “Listing Exchange”), a national securities exchange. Shares of the Fund are traded in the secondary market and elsewhere at market prices that may be at, above or below the Fund’s NAV. Unlike mutual funds, the Fund’s shares are not individually redeemable securities. Rather, the Fund’s shares are redeemable only in Creation Units, and generally, in exchange for portfolio investments and a Cash Component. The size of a Creation Unit to purchase shares of the Fund may differ from the size of a Creation Unit required to redeem shares of the Fund. The size of a Creation Unit may be modified by Janus Henderson Investors US LLC (the “Adviser”) with prior notification to the Fund’s Authorized Participants. See the ETF portion of the Janus Henderson website for the Fund’s current Creation Unit size. In the event of liquidation of the Fund, the number of shares in a Creation Unit may be significantly reduced.

The Fund may charge creation/redemption transaction fees for each creation and redemption. In all cases, transaction fees will be limited in accordance with the requirements of the Securities and Exchange Commission (the “SEC”) applicable to management investment companies offering redeemable securities. Some of the information in this SAI and the Prospectus, such as information about purchasing and redeeming shares from the Fund and transaction fees, is not relevant to most retail investors because it applies only to transactions for Creation Units. Refer to “Creation and Redemption of Creation Units” below.

Once created, the Fund’s shares generally trade in the secondary market, at market prices that change throughout the day, in amounts less than a Creation Unit. Investors purchasing the Fund’s shares in the secondary market through a brokerage account or with the assistance of a broker may be subject to brokerage commissions and charges.

Unlike index-based ETFs, the Fund is “actively managed” and does not seek to replicate the performance of a specified index.

Shares of the Fund are listed for trading and trade throughout the day on the Listing Exchange and other secondary markets. Shares of the Fund may also be listed on certain foreign (non U.S.) exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing under the following circumstances, as may be applicable: (i) if the Listing Exchange becomes aware that the Fund is no longer eligible to operate in reliance on Rule 6c-11, under the Investment Company Act of 1940, as amended (the “1940 Act”); (ii) if the Fund fails to meet certain continuing listing standards of the Listing Exchange; (iii) if following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for at least 30 consecutive trading days; or (iv) if any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will remove the shares of the Fund from listing and trading upon termination of the Fund. In the event the Fund ceases to be listed on an exchange, the Fund may cease operating as an “exchange-traded” fund and operate as a mutual fund, provided that shareholders are given advance notice.

As in the case of other publicly traded securities, when you buy or sell shares through a financial intermediary you will incur a brokerage commission determined by that financial intermediary.

2

Shares of the Fund trade on the Listing Exchange or in the secondary market at prices that may differ from their NAV because such prices may be affected by market forces (such as supply and demand for the Fund’s shares). The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

The Fund is not sponsored, endorsed, sold, or promoted by the Listing Exchange. The Listing Exchange makes no representation or warranty, express or implied, to the owners of shares of the Fund or any member of the public regarding the advisability of investing in securities generally or in the Fund particularly or the ability of the Fund to achieve its investment objectives. The Listing Exchange has no obligation or liability in connection with the administration, marketing, or trading of the Fund.

The 1940 Act classifies funds as either diversified or nondiversified. The Fund is classified as nondiversified.

Janus Henderson Investors US LLC (the “Adviser”) is the investment adviser for the Fund.

The Fund is subject to certain fundamental policies and restrictions that may not be changed without shareholder approval. Shareholder approval means approval by the lesser of: (i) more than 50% of the outstanding voting securities of the Trust (or the Fund if a matter affects just the Fund) or (ii) 67% or more of the voting securities present at a meeting if the holders of more than 50% of the outstanding voting securities of the Trust (or the Fund) are present or represented by proxy. The following policies are fundamental policies of the Fund.

The Fund may not:

(1) Invest 25% or more of the value of its net assets in any particular industry or group of industries (other than U.S. Government securities, including those issued or guaranteed by U.S. Government agencies, instrumentalities or authorities, and securities of other investment companies).

(2) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this limitation shall not prevent the Fund from purchasing or selling foreign currencies, options, futures, swaps, forward contracts, or other derivative instruments, or from investing in securities or other instruments backed by physical commodities).

(3) Lend any security or make any other loan if, as a result, more than one-third of the Fund’s total assets would be lent to other parties (but this limitation does not apply to investments in repurchase agreements, commercial paper, debt securities, or loans, including assignments and participation interests).

(4) Act as an underwriter of securities issued by others, except to the extent that the Fund may be deemed an underwriter in connection with the disposition of its portfolio securities.

(5) Borrow money, except as permitted under the 1940 Act, the rules or regulations thereunder or other governing statute, or any exemption therefrom, as such statute, rules or regulations may be amended or interpreted from time to time, or otherwise as permitted by the SEC or other regulatory agency with authority over the Fund. This policy shall not prohibit short sales transactions, or futures, options, swaps, repurchase transactions (including reverse repurchase agreements), or forward transactions. The Fund may not issue “senior securities” in contravention of the 1940 Act.

(6) Invest directly in real estate or interests in real estate; however, the Fund may own debt or equity securities issued by companies engaged in those businesses.

As a fundamental policy, the Fund may, notwithstanding any other investment policy or limitation (whether or not fundamental), invest all of its assets in the securities of a single open-end management investment company with substantially the same fundamental investment objectives, policies, and limitations as the Fund.

3

The Board of Trustees of the Trust (the “Trustees”) has adopted additional investment restrictions for the Fund. These restrictions are operating policies of the Fund and may be changed by the Trustees without shareholder approval. The additional restrictions adopted by the Trustees to date include the following:

(1) If the Fund is an underlying fund in a fund of funds, the Fund may not acquire securities of other investment companies in reliance on Section 12(d)(1)(F) of the 1940 Act and securities of open-end investment companies or registered unit investment trusts in reliance on Section 12(d)(1)(G) of the 1940 Act.

(2) The Fund may sell securities short if it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short without the payment of any additional consideration therefor (“short sales against the box”). In addition, the Fund may engage in short sales other than against the box, which involve selling a security that the Fund borrows and does not own. The Trustees may impose limits on the Fund’s investments in short sales, as described in the Fund’s Prospectus. Transactions in futures, options, swaps, and forward contracts not involving short sales are not deemed to constitute selling securities short.

(3) The Fund does not intend to purchase securities on margin, except that the Fund may obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments and other deposits in connection with transactions involving short sales, futures, options, swaps, forward contracts, “to be announced” commitments, and other permitted investment techniques shall not be deemed to constitute purchasing securities on margin.

(4) The Fund may not mortgage or pledge any securities owned or held by the Fund in amounts that exceed, in the aggregate, 15% of the Fund’s NAV, provided that this limitation does not apply to: reverse repurchase agreements; deposits of assets to margin; guarantee positions in futures, options, swaps, or forward contracts; or the segregation of assets in connection with such contracts.

(5) The Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets.

(6) The Fund may not invest in companies for the purpose of exercising control of management.

Under the terms of an exemptive order received from the SEC, the Fund may borrow money from or lend money to other funds that permit such transactions and for which the Adviser or one of its affiliates serves as investment adviser. All such borrowing and lending will be subject to the above limits and to the limits and other conditions in such exemptive order. The Fund will borrow money through the program only when the costs are equal to or lower than the cost of bank loans. Interfund loans and borrowings normally extend overnight, but can have a maximum duration of seven days. The Fund will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). The Fund may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed.

Any delay in repayment to the lending Fund could result in a lost investment opportunity or additional borrowing costs, and interfund loans are subject to the risk that the borrowing fund may be unable to repay the loan when due. While it is expected that the Fund may borrow money through the program to satisfy redemption requests or to cover unanticipated cash shortfalls, the Fund may elect to not participate in the program during times of market uncertainty or distress or for other reasons.

For purposes of the Fund’s fundamental policy related to investments in real estate, the policy does not prohibit the purchase of securities directly or indirectly secured by real estate or interests therein, or issued by entities that invest in real estate or interests therein, such as, but not limited to, corporations, partnerships, real estate investment trusts (“REITs”), and other REIT-like entities, such as foreign entities that have REIT characteristics.

Except for the Fund’s policies with respect to investments in illiquid investments and borrowing, the percentage limitations included in these policies and elsewhere in this SAI and/or the Fund’s Prospectus normally apply only at the time of purchase of a security. So, for example, if the Fund exceeds a limit as a result of market fluctuations or the sale of other securities, it will not be required to dispose of any securities.

4

For purposes of the Fund’s policies on investing in particular industries, the Fund utilizes any one or more of the industry sub-classifications used by one or more widely recognized third-party providers and/or as defined by the Adviser. The policy will be interpreted to give broad authority to the Fund as to how to classify issuers within or among industries. The Fund may change any source used for determining industry classifications and sub-classifications without prior shareholder notice or approval.

A discussion of the principal strategies and risks associated with an investment in the Fund is contained in the Fund’s Prospectus under the headings “Principal Investment Strategy,” “Principal Investment Risks,” and “Risks of the Fund.” The discussion below supplements, and should be read in conjunction with, such sections of the Fund’s Prospectus.

General Considerations and Risks

Investments in the Fund should be made with an understanding that the value of the portfolio of securities held by the Fund may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of common stocks generally and other factors.

An investment in the Fund should also be made with an understanding of the risks inherent in an investment in securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the securities markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of Fund shares). Securities are susceptible to general market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic and banking crises.

The principal trading market for some of the securities held by the Fund may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of the Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent or if bid/ask spreads are wide.

Diversification

Funds are classified as either diversified or nondiversified. To be classified as diversified under the 1940 Act, a fund may not, with respect to 75% of its total assets, invest more than 5% of its total assets in any issuer and may not own more than 10% of the outstanding voting securities of an issuer. A fund that is classified as nondiversified under the 1940 Act is not subject to the same restrictions and therefore has the ability to take larger positions in securities than a fund that is classified as diversified. This gives a fund that is classified as nondiversified more flexibility to focus its investments in companies that portfolio management has identified as the most attractive for the investment objective and strategy of the fund. However, because the appreciation or depreciation of a single security may have a greater impact on the NAV of a fund which is classified as nondiversified, its share price can be expected to fluctuate more than a comparable fund which is classified as diversified. This fluctuation, if significant, may affect the performance of a fund.

Artificial Intelligence (“AI”) Risk

The rapid development and increasingly widespread use of certain artificial intelligence technologies, including machine learning models and generative artificial intelligence (collectively “AI Technologies”), may adversely impact markets, the overall performance of the Fund’s investments, or the services provided to the Fund by its service providers. For example, issuers in which the Fund invests and/or service providers to the Fund (including, without limitation, the Fund’s investment adviser, fund accountant, custodian, or transfer agent) may use and/or expand the use of AI Technologies in their business operations, and the challenges with properly managing its use could result in reputational harm, competitive harm, legal liability, and/or an adverse effect on business operations. AI Technologies are highly reliant on the collection and analysis of large amounts of data and complex algorithms, and it is possible that the information provided through use of AI Technologies could be insufficient, incomplete, inaccurate or biased leading to adverse effects for the Fund, including, potentially, operational errors and investment losses. Additionally, the use of AI Technologies could impact the market as a whole, including by way of use by malicious actors for market manipulation, fraud and cyberattacks, and may face regulatory scrutiny in the future, which could limit the development of this technology and impede the growth of companies that develop and use AI. To the extent the Fund invests in companies that are involved in various aspects of AI Technologies, it

5

is particularly sensitive to the risks of those types of companies. These risks include, but are not limited to, small or limited markets for such securities, changes in business cycles, world economic growth, technological progress, rapid obsolescence, and government regulation. Such companies may have limited product lines, markets, financial resources or personnel. Securities of such companies, especially smaller, start-up companies, tend to be more volatile than securities of companies that do not rely heavily on technology. Rapid change to technologies that affect a company’s products could have a material adverse effect on such company’s operating results. Companies that are extensively involved in AI Technologies also may rely heavily on a combination of patents, copyrights, trademarks and trade secret laws to establish and protect their proprietary rights in their products and technologies. There can be no assurance that the steps taken by these companies to protect their proprietary rights will be adequate to prevent the misappropriation of their technology or that competitors will not independently develop technologies that are substantially equivalent or superior to such companies’ technology. Such companies may engage in significant amounts of spending on research and development, and there is no guarantee that the products or services produced by these companies will be successful. Actual usage of AI Technologies by the Fund’s service providers and issuers in which the Fund invests will vary. AI Technologies and their current and potential future applications, and the regulatory frameworks within which they operate, continue to rapidly evolve, and it is impossible to predict the full extent of future applications or regulations and the associated risks to the Fund.

Cash Position

As discussed in the Prospectus, the Fund’s cash position may temporarily increase under various circumstances. Securities that the Fund may invest in as a means of receiving a return on uninvested cash include U.S. treasury securities, domestic commercial paper, certificates of deposit, repurchase agreements, or other short-term debt obligations. These securities may include U.S. cash instruments and cash equivalent securities. The Fund may also invest in affiliated or non-affiliated money market funds (including private funds operating as money market funds that are not registered under the 1940 Act) (refer to “Investment Company Securities”).

For temporary defensive purposes, the Fund may invest a portion of its assets in cash or other short-term instruments.

Concentration Risk

To the extent the Fund focuses its investments in any single type of investment, including in a given industry, sector, country, region, or types of security, companies in its portfolio may share common characteristics and react similarly to market developments. For example, changes in government funding or subsidies, new or anticipated legislative changes, or technological advances could affect the value of such companies and, therefore, the Fund’s net asset value. As a result, the Fund may be subject to greater risks and its net asset value may fluctuate more than a fund that does not concentrate its investments.

Confidential Information

With respect to certain transactions, including but not limited to private placements, the Fund may determine not to receive confidential information. Such a decision may place the Fund at a disadvantage relative to other investors who determine to receive confidential information, as the Fund may be limited in its available investments or unable to make accurate assessments related to certain investments.

In cases where the Adviser receives material, nonpublic information about the issuers of securities that may be held in the Fund’s holdings, the Adviser’s ability to trade in these securities for the account of the Fund could potentially be limited by its possession of such information, to the extent necessary to comply with certain regulatory restrictions. Such limitations on the ability to trade in the securities of the issuer could have an adverse effect on the Fund by, for example, preventing the Fund from selling a security that is experiencing a material decline in value. In some instances, these trading restrictions could continue in effect for a substantial period of time.

In addition, because the Fund becomes a creditor of an issuer when holding a security, the Adviser may from time to time participate on creditor committees on behalf of the Fund. These are committees formed by creditors to negotiate with management of the issuer and are intended to protect the rights of bondholders in the event of bankruptcy, bond covenant default, or other issuer-related financial problems. Participation on creditor committees may expose the Adviser or the Fund to material non-public information of the issuer, restricting the Fund’s ability to trade in or acquire additional positions in a particular security or other securities of the issuer when it might otherwise desire to do so. Participation on creditor committees may also expose the Fund to federal bankruptcy laws or other laws governing rights of debtors and creditors. Additionally, such participation may subject the Fund to expenses such as legal fees. The Adviser will only participate on creditor committees on behalf of the Fund when it believes such participation is necessary or desirable to protect the value of portfolio securities or enforce the Fund’s rights as a creditor.

6

Cyber Security Risk

The Fund is susceptible to operational and information security risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to, infection by computer viruses or other malicious software code, gaining unauthorized access to systems, networks, or devices that are used to service the Fund’s operations through “hacking” or other means for the purpose of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on the Fund’s websites or a service provider’s systems, which renders them inoperable to intended users until appropriate actions are taken. In addition, authorized persons could inadvertently or intentionally release confidential or proprietary information stored on the Fund’s systems.

Cyber security failures or breaches by the Fund’s service providers (including, but not limited to, the Adviser, custodians, transfer agents, subadministrators, and financial intermediaries) may subject the Fund to many of the same risks associated with direct cyber security failures or breaches, and may cause disruptions and impact the service providers’ and the Fund’s business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business and the Fund to process transactions, inability to calculate the Fund’s net asset value, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. The Fund may incur incremental costs to prevent cyber incidents in the future. The Fund could be negatively impacted as a result. While the Adviser has established business continuity plans and risk management systems designed to prevent or reduce the impact of such cyber-attacks, there are inherent limitations in such plans and systems due in part to the ever-changing nature of technology and cyber-attack tactics. As such, there is a possibility that certain risks have not been adequately identified or prepared for. Furthermore, the Fund cannot directly control any cyber security plans and systems put in place by third party service providers or their service providers. Cyber security risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund’s investment in such securities to lose value. The rapid development and increasingly widespread use of AI could increase the effectiveness of cyber-attacks and exacerbate the risks.

Depositary Receipts

American Depositary Receipts (“ADRs”) are receipts issued by an American bank or trust company evidencing ownership of underlying securities issued by a foreign issuer. ADRs, in registered form, are designed for use in U.S. securities markets. Unsponsored ADRs may be created without the participation of the foreign issuer. Holders of these ADRs generally bear all the costs of the ADR facility, whereas foreign issuers typically bear certain costs in a sponsored ADR. The bank or trust company depositary of an unsponsored ADR may be under no obligation to distribute shareholder communications received from the foreign issuer or to pass through voting rights. The Fund may invest in American Depositary Shares (“ADSs”), which are U.S. dollar-denominated equity shares of a foreign-based company available for purchase on an American stock exchange. ADSs are issued by depository banks in the United States under an agreement with the foreign issuer. The entire issuance is called an ADR and the individual shares are referred to as ADSs.

Depositary receipts are generally subject to the same sort of risks as direct investments in a foreign country, such as currency risk, political and economic risk, regulatory risk, market risk, and geographic investment risk, because their values depend on the performance of a foreign security denominated in its home currency. The risks of foreign investing are addressed in the Fund’s Prospectus.

Derivative Instruments

A derivative is a financial instrument whose performance is derived from the performance of another, underlying asset.

Subject to its investment objective and policies, the Fund may use derivative instruments for hedging purposes (to manage and mitigate risks associated with an investment, currency exposure, or market conditions), to manage duration (i.e., sensitivity of the portfolio to changes in interest rates), or to seek to enhance return or earn income by, for example, using put or call options to receive income based on portfolio management’s view of the future direction of interest rates, credit or a specific currency.

The Fund may not use any derivative to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly. The Fund’s ability to use derivative instruments may also be limited by tax considerations (see “Income Dividends, Capital Gains Distributions, and Tax Status”).

7

Investments in derivatives in general are subject to market risks that may cause their prices to fluctuate over time. Investments in derivatives may not directly correlate with the price movements of the underlying instrument. As a result, the use of derivatives may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities underlying those derivatives. The use of derivatives may result in larger losses or smaller gains than otherwise would be the case. Derivatives can be volatile and may involve significant risks, including:

Counterparty Risk. Counterparty risk is the risk that the counterparty (the party on the other side of the transaction) on a derivative transaction will be unable to honor its financial obligation to the Fund.

Currency Risk. Currency risk is the risk that changes in the exchange rate between currencies will adversely affect the value (in U.S. dollar terms) of an investment.

Leverage Risk. Leverage risk is the risk associated with certain types of leveraged investments or trading strategies pursuant to which relatively small market movements may result in large changes in the value of an investment. The Fund creates leverage by investing in instruments where the investment loss can exceed the original amount invested. The use of investment techniques, such as short sales and certain derivative transactions, can create a leveraging effect on the Fund, which can result in losses that greatly exceed the amount originally invested by the Fund.

Liquidity Risk. Liquidity risk is the risk that certain securities may be difficult or impossible to sell at the time that the seller would like or at the price that the seller believes the security is currently worth.

Index Risk. Index risk is the risk that the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index. If the index changes, the Fund could receive lower interest payments or experience a reduction in the value of the derivative to below what the Fund paid. Certain indexed securities, including inverse securities (which move in an opposite direction to the index), may create leverage, to the extent that they increase or decrease in value at a rate that is a multiple of the changes in the applicable index.

Derivatives may generally be traded over-the-counter (“OTC”) or on an exchange. Derivatives traded OTC are agreements that are individually negotiated between parties and can be tailored to meet a purchaser’s needs. OTC derivatives are not guaranteed by a clearing agency and may be subject to increased counterparty risk.

In an effort to mitigate counterparty risk associated with derivatives traded OTC, the Fund may enter into collateral agreements with certain counterparties whereby, subject to certain minimum exposure requirements, the Fund may require the counterparty to post collateral if the Fund has a net aggregate unrealized gain on all OTC derivative contracts with a particular counterparty. There is no guarantee that counterparty exposure is reduced by using collateral and these arrangements are dependent on the Adviser’s ability to establish and maintain appropriate systems and trading.

The Adviser has filed a notice of eligibility for exemption from the definition of the term “commodity pool operator” with respect to the Fund in accordance with Rule 4.5 of the Commodity Exchange Act and, therefore, the Adviser is not subject to regulation as a commodity pool operator under the Commodity Exchange Act with respect to the Fund. The Fund may enter into futures contracts and related options as permitted under Rule 4.5. The Adviser will become subject to increased CFTC regulation if the Fund invests more than a prescribed level of its assets in such instruments, or if the Fund markets itself as providing investment exposure to these instruments. If the Fund cannot meet the requirements of Rule 4.5, the Adviser and the Fund would need to comply with certain disclosure, reporting, and recordkeeping requirements. The Adviser is registered as a commodity pool operator in connection with the operation of one or more other Janus Henderson mutual funds which do not qualify for the Rule 4.5 exemption.

Risk of Government Regulation. Rule 18f-4 under the 1940 Act governs the Fund’s use of derivative instruments and certain other transactions that create future payment and/or delivery obligations by the Fund. Rule 18f-4 permits the Fund to enter into derivatives and certain other transactions notwithstanding the restrictions on the issuance of “senior securities” under Section 18 of the 1940 Act. Section 18 of the 1940 Act, among other things, prohibits open-end funds, including the Fund, from issuing or selling any “senior security,” other than borrowing from a bank (subject to a requirement to maintain 300% “asset coverage”). In connection with the adoption of Rule 18f-4, the SEC eliminated the asset segregation framework arising from prior SEC guidance for covering derivatives transactions and certain financial instruments.

Pursuant to Rule 18f-4, the Fund has adopted and implemented a derivatives risk management program (“DRMP”) designed to identify, assess, and reasonably manage the risks associated with derivatives and certain other transactions. Under the DRMP, the Fund is required to comply with certain value-at-risk (VaR)-based leverage limits (VaR is an

8

estimate of an instrument’s or portfolio’s potential losses over a given time horizon and at a specified confidence level). The DRMP is administered by a “derivatives risk manager,” who is approved by the Trustees, and who periodically reviews the DRMP and reports to the Trustees. While the Fund is not required to segregate assets to cover derivatives transactions and certain financial instruments pursuant to Rule 18f-4, the Fund will continue to do so for other instruments as required under applicable federal securities laws.

In addition, the SEC, the Commodity Futures Trading Commission (“CFTC”), and the exchanges are authorized to take extraordinary actions in the event of a market emergency, including, for example, the implementation or reduction of speculative position limits, the implementation of higher margin requirements, the establishment of daily price limits and the suspension of trading. It is not possible to predict fully the effects of current or future regulation. However, it is possible that developments in government regulation of various types of derivative instruments may limit or prevent the Fund from using these instruments effectively as a part of its investment strategy, and could adversely affect the Fund’s ability to achieve its investment objective. The Fund will continue to monitor developments in the area, particularly to the extent regulatory changes affect the ability to enter into derivative transactions. New requirements, even if not directly applicable to the Fund, may increase the cost of the Fund’s investments and cost of doing business.

Equity Securities

The Fund may invest in equity securities, which include, but are not limited to, common and preferred stocks and securities convertible or exchangeable into common stock.

Common Stock. Common stock represents a proportionate share of the ownership of a company. Common stocks sometimes are divided into several classes, with each class having different voting rights, dividend rights, or other differences in their rights and priorities. The value of a stock is based on the market’s assessment of the current and future success of a company’s business, any income paid to stockholders, the value of the company’s assets, and general market conditions. The value of a stock may also be adversely affected by other factors such as accounting irregularities, actual or perceived weaknesses in corporate governance practices of a company’s board or management, and changes in company management. Common stock values can fluctuate dramatically over short periods.

Preferred Stock. A preferred stock represents an ownership interest in a company, but pays dividends at a specific rate and has priority over common stock in payment of dividends and liquidation claims. Preferred stock dividends are generally cumulative, noncumulative, or participating. “Cumulative” dividend provisions require all or a portion of prior unpaid dividends to be paid before dividends can be paid to the issuer’s common stock. “Participating” preferred stock may be entitled to a dividend exceeding the stated dividend in certain cases. Like debt securities, the value of a preferred stock often fluctuates more in response to changes in interest rates and the creditworthiness of the issuer, rather than in response to changes in the issuer’s profitability and business prospects. Preferred stock is subject to similar risks as common stock and debt securities.

Convertible Security. A convertible security is generally a debt obligation or preferred stock that may be converted within a specified period of time into a certain amount of common stock of the same or a different issuer. A convertible security, such as a “convertible preferred stock,” provides a fixed-income stream and the opportunity, through its conversion feature, to participate in the capital appreciation resulting from a market price advance in its underlying common stock. Like a common stock, the value of a convertible security tends to increase as the market value of the underlying stock rises, and it tends to decrease as the market value of the underlying stock declines. As with a fixed-income security, a convertible security tends to increase in market value when interest rates decline and decrease in value when interest rates rise. Because both interest rate and market movements can influence its value, a convertible security is not as sensitive to interest rates as a similar fixed-income security, nor is it as sensitive to changes in share price as its underlying stock.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at prices above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates.

9

A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Synthetic convertible securities are created by combining separate securities that possess the two principal characteristics of a traditional convertible security, i.e., an income-producing security (“income-producing component”) and the right to acquire an equity security (“convertible component”). The income-producing component is achieved by investing in non-convertible, income-producing securities such as bonds, preferred stocks and money market instruments, which may be represented by derivative instruments. The convertible component is achieved by investing in securities or instruments such as warrants or options to buy common stock at a certain exercise price, or options on a stock index. Unlike a traditional convertible security, which is a single security having a single market value, a synthetic convertible security is comprised of two or more separate securities, each with its own market value. Therefore, the “market value” of a synthetic convertible security is the sum of the values of its income-producing component and its convertible component. For this reason, the values of a synthetic convertible security and a traditional convertible security may respond differently to market fluctuations.

More flexibility is possible in the assembly of a synthetic convertible security than in the purchase of a convertible security. Although synthetic convertible securities may be selected where the two components are issued by a single issuer, thus making the synthetic convertible security similar to the traditional convertible security, the character of a synthetic convertible security allows the combination of components representing distinct issuers. A synthetic convertible security also is a more flexible investment in that its two components may be purchased separately. For example, the Fund may purchase a warrant for inclusion in a synthetic convertible security but temporarily hold short-term investments while postponing the purchase of a corresponding bond pending development of more favorable market conditions.

A holder of a synthetic convertible security faces the risk of a decline in the price of the security or the level of the index involved in the convertible component, causing a decline in the value of the security or instrument, such as a call option or warrant, purchased to create the synthetic convertible security. Should the price of the stock fall below the exercise price and remain there throughout the exercise period, the entire amount paid for the convertible component would be lost. Because a synthetic convertible security includes the income-producing component as well, the holder of a synthetic convertible security also faces the risk that interest rates will rise, causing a decline in the value of the income-producing instrument.

Warrants. Warrants constitute options to purchase equity securities at a specific price and are valid for a specific period of time. They do not represent ownership of the equity securities, but only the right to buy them. Warrants have no voting rights, pay no dividends, and have no rights with respect to the assets of the corporation issuing them. Warrants differ from call options in that warrants are issued by the issuer of the security that may be purchased on their exercise, whereas call options may be issued by anyone. The prices of warrants do not necessarily move parallel to the prices of the underlying equity securities. The price usually represents a premium over the applicable market value of the common stock at the time of the warrant’s issuance. Investments in warrants involve certain risks, including the possible lack of a liquid market for the resale of the warrants, potential price fluctuations as a result of speculation or other factors, and failure of the price of the common stock to rise. The price of a warrant may be more volatile than the price of its underlying security. A warrant becomes worthless if it is not exercised within the specified time period.

ESG Exclusions Policy

The Adviser has adopted a firmwide environmental, social, and governance (“ESG”) exclusions policy that generally applies to the accounts it manages, including the Fund. Using third-party inputs, the Adviser applies exclusionary criteria to seek to avoid investing in securities of issuers that, in the determination of the Adviser, manufacture cluster munitions, anti-personnel mines, chemical weapons, and biological weapons.

Exchange-Traded Funds

The Fund may invest in affiliated or unaffiliated ETFs to gain exposure to a particular portion of the market, to assist with cash management, and/or for other purposes. ETFs are typically open-end investment companies that are traded on a national securities exchange. ETFs typically incur fees, such as investment advisory fees and other operating expenses that are separate from those of the Fund, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund may be higher than the cost of investing directly in ETFs. Since ETFs are traded on an exchange at market prices that may vary

10

from the net asset value of their underlying investments, there may be times when ETFs trade at a premium or discount. In the case of affiliated ETFs, unless waived, the Fund’s adviser will earn fees both from the Fund and from the underlying ETF, with respect to assets of the Fund invested in the underlying ETF. The Fund is also subject to the risks associated with the securities in which the ETF invests.

Foreign Securities

The Fund may invest in foreign securities either indirectly (e.g., depositary receipts, depositary shares, and passive foreign investment companies) or directly in foreign markets, including emerging markets. The Fund may also engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time. Investments in foreign securities, including securities of foreign and emerging market governments, may involve greater risks than investing in domestic securities because the Fund’s performance may depend on factors other than the performance of a particular company. These risks may include:

Currency Risk. As long as the Fund holds a foreign currency-denominated security, its value will be affected by the value of the local currency relative to the U.S. dollar. When the Fund sells a foreign currency-denominated security, its value may be worth less in U.S. dollars even if the security increases in value in its home country. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk, as the value of these securities may also be affected by changes in the issuer’s local currency.

Foreign Market Risk. Foreign securities markets, particularly those of emerging market countries, may be less liquid and more volatile than domestic markets. These securities markets may trade a small number of securities, may have a limited number of issuers and a high proportion of shares, or may be held by a relatively small number of persons or institutions. Local securities markets may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of substantial holdings difficult or impossible at times. It is also possible that certain markets may require payment for securities before delivery, and delays may be encountered in settling securities transactions. In some foreign markets, there may not be protection against failure by other parties to complete transactions. The Fund could be adversely affected by delays in, or a refusal to grant, any required approval for repatriation of capital, dividends, interest, and other income from a particular country or governmental entity. In addition, securities of issuers located in or economically tied to countries with emerging markets may have limited marketability and may be subject to more abrupt or erratic price movements which could also have a negative effect on the Fund. Such factors may hinder the Fund’s ability to buy and sell emerging market securities in a timely manner, affecting the Fund’s investment strategies and potentially affecting the value of the Fund.

Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in a particular country or geographic region, the Fund will generally have more exposure to certain risks due to possible political, economic, social, regulatory events, and conflicts in that country or region. Adverse developments in certain regions could also adversely affect securities of other countries whose economies appear to be unrelated and could have a negative impact on the Fund’s performance. The foregoing may result in a negative impact on Fund performance and the value of an investment in the Fund, even beyond any direct investment exposure the Fund may have to issuers located in or with significant exposure to an impacted country or geographic region.

Similarly, a particular country or geographic region may be more prone to and economically sensitive to environmental events such as, but not limited to, hurricanes, earthquakes, typhoons, flooding, tidal waves, tsunamis, erupting volcanoes, wildfires or droughts, tornadoes, mudslides, or other weather-related phenomena. Such disasters, and the resulting physical or economic damage, could have a severe and negative impact on the Fund’s investment portfolio and, in the longer term, could impair the ability of issuers in which the Fund invests to conduct their businesses as they would under normal conditions. Adverse weather conditions may also have a particularly significant negative effect on issuers in the agricultural sector and on insurance and reinsurance companies that insure or reinsure against the impact of natural disasters.

Political and Economic Risk. Foreign investments may be subject to heightened political and economic risks, particularly in emerging markets which may have relatively unstable governments, immature economic structures, national policies restricting investments by foreigners, social instability, trade disputes, and different and/or developing legal systems. In some countries, there is the risk that the government may take over the assets or operations of a company or that the government may impose withholding and other taxes or limits on the removal of the Fund’s assets from that country. Further, acts of terrorism in the United States or other countries may cause uncertainty in the financial

11

markets and adversely affect the performance of the issuers to which the Fund has exposure. In addition, the economies of emerging markets may be predominantly based on only a few industries, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates.

Regulatory and Transaction Risk. There may be less government supervision of foreign markets. As a result, foreign issuers may not be subject to the uniform accounting, auditing, and financial reporting standards and practices applicable to domestic issuers, and there may be less publicly available information about foreign issuers. In addition, costs of buying, selling, and holding foreign securities, including brokerage, tax, and custody costs, may be higher than those involved in domestic transactions.

Settlement Risk. Markets in different countries have different clearance and settlement procedures and in certain markets there have been times when settlements have been unable to keep pace with the volume of transactions. Delays in settlement may increase credit risk to the Fund, limit the ability of the Fund to reinvest the proceeds of a sale of securities, and potentially subject the Fund to penalties for its failure to deliver to subsequent purchasers of securities whose delivery to the Fund was delayed. Delays in the settlement of securities purchased by the Fund may limit the ability of the Fund to sell those securities at times and prices it considers desirable, and may subject the Fund to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. The Fund may be required to borrow monies it had otherwise expected to receive in connection with the settlement of securities.

Trade Disputes. Countries that are economically dependent on large import or export sectors may be adversely affected by trade disputes with key trading partners, tariffs imposed on goods and services, and protectionist monetary policies generally. An economic slowdown in a country’s export sector may also affect companies that are not heavily dependent on exports. To the extent a country engages in retaliatory tariffs, a company that relies on imports to produce its own goods may experience increased costs of production or reduced profitability, which may affect consumers, investors and the domestic economy. Trade disputes and retaliatory actions may include embargoes and other trade limitations, which may trigger a significant reduction in international trade and impact the global economy. Trade disputes may also lead to increased currency exchange rate volatility, which can adversely affect the prices of Fund securities valued in U.S. dollars. The potential threat of trade disputes may also negatively affect investor confidence in the markets generally and investment growth.

Illiquid Investments

The Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid investments that are assets. Illiquid investments, which include certain securities that are purchased in private placements, are securities that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. Certain securities previously deemed liquid may become illiquid over time, particularly in periods of economic distress.

If illiquid investments that are assets exceed 15% of the Fund’s net assets, the Fund will take steps to reduce its holdings of such illiquid investments to or below 15% of its net assets within a reasonable period of time. Because illiquid investments may not be readily marketable, portfolio management may not be able to dispose of them in a timely manner. As a result, the Fund may be forced to hold illiquid investments while their price depreciates. Depreciation in the price of illiquid investments may cause the NAV of the Fund to decline.

Investment Company Securities

From time to time, the Fund may invest in securities of other investment companies, subject to the provisions of the 1940 Act or as otherwise permitted by the SEC. Section 12(d)(1) of the 1940 Act prohibits the Fund from acquiring: (i) more than 3% of another investment company’s voting stock; (ii) securities of another investment company with a value in excess of 5% of the Fund’s total assets; or (iii) securities of such other investment company and all other investment companies owned by the Fund having a value in excess of 10% of the Fund’s total assets. In addition, Section 12(d)(1) prohibits another investment company from selling its shares to the Fund if, after the sale: (i) the Fund owns more than 3% of the other investment company’s voting stock or (ii) the Fund and other investment companies, and companies controlled by them, own more than 10% of the voting stock of such other investment company. To the extent the Fund is an underlying fund in a fund of funds managed by the Adviser, the Fund may not acquire securities of other investment companies in reliance on Section 12(d)(1)(F) and securities of open-end investment companies or registered unit investment trusts in reliance on Section 12(d)(1)(G). The Fund may invest in other investment companies beyond these statutory limits to the extent the Fund abides by certain conditions of Rule 12d1-4 under the 1940 Act. The Fund may invest its cash holdings in affiliated or

12

non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provision of the 1940 Act that governs the operation of money market funds as part of a cash sweep program. The Fund may purchase unlimited shares of affiliated or non-affiliated money market funds and of other funds managed by the Adviser, whether registered or unregistered entities, as permitted by the 1940 Act and rules promulgated thereunder.

To the extent the Fund invests in money market funds or other funds, the Fund will be subject to the same risks that investors experience when investing in such other funds. These risks may include the impact of significant fluctuations in assets as a result of the cash sweep program or purchase and redemption activity by affiliated or non-affiliated shareholders in such other funds. Additionally, to the extent that the Adviser serves as the investment adviser to underlying Janus Henderson funds or investment vehicles in which the Fund may invest, the Adviser may have conflicting interests in fulfilling its fiduciary duties to both the Fund and the underlying funds or investment vehicles. Money market funds are open-end registered investment companies. Money market funds that meet the definition of a retail money market fund or government money market fund generally compute their price per share using the amortized cost method of valuation to seek to maintain a stable $1.00 price per share, and money market funds that do not meet the definitions of a retail money market fund or government money market fund transact at a floating NAV per share (similar to all other non-money market mutual funds). Money market funds may impose liquidity fees because of market conditions or other factors. Amendments to money market fund regulation could impact the trading and value of money market instruments, which may negatively affect the Fund’s return potential.

As a shareholder of another investment company, the Fund would bear its pro rata portion of the other investment company’s expenses, including advisory fees, in addition to the expenses the Fund bears directly in connection with its own operation. The market prices of ETFs and closed-end funds will fluctuate in accordance with both changes in the market value of their underlying portfolio investments and due to supply and demand for the instruments on the exchanges on which they are traded (which may result in their trading at a discount or premium to their NAVs). If the market price of shares of an ETF or closed-end fund decreases below the price that the Fund paid for the shares and the Fund were to sell its shares of such investment company at a time when the market price is lower than the price at which it purchased the shares, the Fund would experience a loss.

Issuer Concentration

The Fund’s portfolio may be comprised of a relatively small number of issuers in comparison to other funds. As a result, the Fund may be subject to greater risks than a fund that invests in a greater number of issuers. A change in the value of any single investment held by the Fund may affect the overall value of the Fund more than it would affect a fund that holds more investments. In particular, the Fund may be more susceptible to adverse developments affecting any single issuer held by the Fund and may be susceptible to greater losses because of these developments. A portfolio of a small number of issuers may also have elevated risks to changes in general economic conditions, cyclical market patterns, adverse labor relations, political events, obsolescence of technologies, and increased competition that may negatively affect the profitability or viability of an issuer. The Fund’s investment strategy to concentrate its portfolio on a smaller number of holdings could result in more volatility in the Fund’s performance and share price.

Money Market Instruments

The Fund may invest a portion of its assets in high-quality money market instruments on an ongoing basis to provide liquidity. The instruments in which the Fund may invest include: (i) short-term obligations issued by the U.S. Government; (ii) negotiable certificates of deposit (“CDs”), fixed time deposits and bankers’ acceptances of U.S. and foreign banks and similar institutions; (iii) commercial paper; (iv) repurchase agreements; and (v) money market mutual funds. CDs are short-term negotiable obligations of commercial banks. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Banker’s acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Operational Risk

An investment in the Fund can involve operational risks arising from factors such as processing errors, human errors, inadequate or failed internal or external processes, failures in systems and technology, changes in personnel, and errors caused by third party service providers. Among other things, these errors or failures, as well as other technological issues, may adversely affect the Fund’s ability to calculate its net asset value in a timely manner, including over a potentially extended period of time. These errors or failures may also result in a loss or compromise of information, regulatory scrutiny,

13

reputational damage or other events, any of which could have a material adverse effect on the Fund. While the Fund seeks to minimize such events through internal controls and oversight of third party service providers, there is no guarantee that the Fund will not suffer losses if such events occur.

Real Estate Investment Trusts (“REITs”) and Real Estate Operating Companies (“REOCs”)

Within the parameters of its specific investment policies, the Fund may invest in REITs and REIT-like entities, including REOCs. REITs are sometimes informally characterized as equity REITs, mortgage REITs, and hybrid REITs. In addition, the Fund may gain exposure to the real estate sector by investing in common, preferred and convertible securities of issuers in real estate-related industries. Investments in publicly traded REITs and real estate-linked investments are subject to risks similar to those associated with direct ownership of real estate, including loss to casualty or condemnation, increases in property taxes and operating expenses, zoning law amendments, changes in interest rates, overbuilding and increased competition, variations in market value, fluctuations in rental income, possible environmental liabilities, regulatory limitations on rent, and other risks related to local or general economic conditions. Equity REITs generally experience these risks directly through fee or leasehold interests, whereas mortgage REITs generally experience these risks indirectly through mortgage interests, unless the mortgage REIT forecloses on the underlying real estate. Changes in interest rates may also affect the value of the Fund’s investment in publicly traded REITs. For instance, during periods of declining interest rates, certain mortgage REITs may hold mortgages that the mortgagors elect to prepay, and prepayment may diminish the yield on securities issued by those REITs.

Certain REITs have relatively small market capitalizations, which may tend to increase the volatility of the market price of their securities. Furthermore, publicly traded REITs are dependent upon specialized management skills, have limited diversification and are, therefore, subject to risks inherent in operating and financing a limited number of projects. Publicly traded REITs are also subject to heavy cash flow dependency, defaults by borrowers, and the possibility of failing to qualify for tax-free pass-through of income under the Internal Revenue Code and to maintain exemption from the registration requirements of the 1940 Act. By investing in publicly traded REITs indirectly through the Fund, a shareholder will bear not only his or her proportionate share of the expenses of the Fund, but also, indirectly, similar expenses of the publicly traded REITs. In addition, publicly traded REITs depend generally on their ability to generate cash flow to make distributions to shareholders.

REOCs are publicly traded real estate companies that typically engage in the development, management or financing of real estate that have not elected (or are not eligible) to be taxed as a REIT. Instead, REOCs are generally structured as “C” corporations under the Internal Revenue Code and, as a result, are not required to distribute any portion of their income. In this regard, although REOCs do not receive the same favorable tax treatment that is accorded to REITs, REOCs are typically subject to fewer restrictions than REITs, including the ability to retain and/or reinvest funds from operations. The value of investments in REOCs will generally be affected by the same factors that adversely affect REIT investments; however, REOCs may also be adversely affected by income streams derived from businesses other than real estate ownership.

Regulatory Changes and Market Events and Risks

Federal, state, and foreign governments, regulatory agencies, and self-regulatory organizations may take actions that affect the regulation of the Fund or the instruments in which the Fund invests, or the issuers of such instruments, in ways that are unforeseeable. Future legislation or regulation or other governmental actions could limit or preclude the Fund’s ability to achieve its investment objectives or otherwise adversely impact an investment in the Fund. Furthermore, worsened market conditions, including as a result of U.S. government shutdowns or the perceived creditworthiness of the United States, could have a negative impact on securities markets.

Economic downturns can prompt various economic, legal, budgetary, tax, and regulatory reforms across the globe. In the aftermath of the 2007-2008 financial crisis, the financial sector experienced reduced liquidity in credit and other fixed-income markets, and an unusually high degree of volatility, both domestically and internationally. In response to the crisis, the United States and certain foreign governments, along with the U.S. Federal Reserve and certain foreign central banks, took a number of unprecedented steps designed to support the financial markets, which provided for widespread regulation of the financial industry, including expanded federal oversight in the financial sector. The U.S. government and the Federal Reserve, as well as certain foreign governments and central banks, took extraordinary actions to support local and global economies and the financial markets in response to the COVID-19 pandemic. This and other future government interventions into the economy and financial markets may not work as intended.

14

Policy and legislative changes in the United States and in other countries continue to impact many aspects of financial regulation. For example, some countries, including the United States have adopted and/or are considering the adoption of more protectionist trade policies. The rise in protectionist trade policies, with potential changes to some international trade agreements, may affect the global economy in ways that cannot be presently foreseen.

The value and liquidity of the Fund’s holdings are also generally subject to the risk of significant future local, national, or global economic or political disruptions or slowdowns in the markets in which the Fund invests, especially given that the economies and financial markets throughout the world are becoming increasingly interconnected and reliant on each other. In the event of such an occurrence, the issuers of securities held by the Fund may experience significant declines in the value of their assets and even cease operations, or may require government assistance that is contingent on increased restrictions on their business operations or their government interventions. In addition, it is not certain that the U.S. government or foreign governments will intervene in response to a future market disruption and the effect of any such future intervention cannot be predicted.

Widespread disease, including pandemics and epidemics, and natural or environmental disasters, including those which may be attributable to global climate change, such as earthquakes, fires, floods, hurricanes, tsunamis and weather-related phenomena generally have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Fund’s investments. Economies and financial markets throughout the world have become increasingly interconnected, which increases the likelihood that events, conflicts, or conditions in one region or country will adversely affect markets or issuers in other regions or countries, including the United States. These disruptions could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact the Fund’s ability to achieve its investment objective(s). Any such event(s) could have a significant adverse impact on the value of the Fund’s assets. In addition, these disruptions could also impair the information technology and other operational systems upon which the Fund’s service providers, including the Adviser, rely, and could otherwise disrupt the ability of employees of the Fund’s service providers to perform essential tasks on behalf of the Fund.

Risk of Investing in Emerging Markets

Developing countries or emerging market countries include, but are not limited to, countries included in either the MSCI Emerging Markets Index, and/or the International Monetary Fund’s (“IMF’s”) list of Emerging and Developing Economies. Investing in emerging markets involves certain risks not typically associated with investing in the United States and imposes risks greater than, or in addition to, the risks associated with investing in securities of more developed foreign countries as previously discussed under “Foreign Securities.” The prices of investments in emerging markets can experience sudden and sharp price swings. In many developing markets, there is less government supervision and regulation of business and industry practices (including the potential lack of strict finance and accounting controls and standards), stock exchanges, brokers, and listed companies than in more developed markets. Similarly, issuers in such markets may not be subject to regulatory, disclosure, accounting, auditing, and financial reporting and recordkeeping standards comparable to those to which U.S. companies are subject. Information about emerging market companies, including financial information, may be less available or reliable and the Fund’s ability to conduct due diligence with respect to such companies may be limited. In addition, certain emerging market jurisdictions may materially restrict the Public Company Accounting Oversight Board’s (“PCAOB”) inspection, investigation and enforcement capabilities which impairs the ability to conduct independent oversight or inspection of accounting firms located in or operating in certain emerging markets; therefore, there is no guarantee that the quality of financial reporting or the audits conducted by audit firms of emerging market issuers meet PCAOB standards. Accordingly, these investments may be potentially more volatile in price and less liquid than investments in developed securities markets, resulting in greater risk to investors. There is a risk in developing countries that a current or future economic or political crisis could lead to price controls, forced mergers of companies, expropriation or confiscatory taxation, imposition or enforcement of foreign ownership limits, seizure, nationalization, sanctions or imposition of restrictions by various governmental entities on investment and trading, or creation of government monopolies, any of which may have a detrimental effect on the Fund’s investments.

Many emerging market countries have experienced substantial, and in some periods extremely high, rates of inflation or deflation for many years, and future inflation may adversely affect the economies and securities markets of such countries. In addition, the economies of developing countries tend to be heavily dependent upon international trade and, as such, have been, and may continue to be, adversely impacted by trade barriers, exchange controls, managed adjustments in relative currency values, and other protectionist measures. Developing countries may also experience a higher level of exposure and vulnerability to the adverse effects of climate change. This may be attributed to both the geographic location of emerging

15

market countries and/or a country’s lack of access to technology or resources to adjust and adapt to its effects. An increased occurrence and severity of natural disasters and extreme weather events such as droughts and decreased crop yields, heat waves, flooding and rising sea levels, and increased spread of disease, could cause harmful effects to the performance of affected economies. These economies also have been, and may continue to be, adversely affected by economic conditions in the countries with which they do business. Emerging markets may be subject to a higher degree of corruption and fraud than developed markets, and financial institutions and transaction counterparties may have less financial sophistication, creditworthiness and/or resources than participants in developed markets.

The securities markets of many of the emerging market countries in which the Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those in the United States. Moreover, the legal remedies for investors in emerging markets or other legal systems to ensure orderly enforcement of property interests such as bankruptcy may be more limited than the remedies available in the United States. Additionally, the ability of U.S. authorities (e.g., the SEC and the U.S. Department of Justice) to bring actions against bad actors may be limited. A shareholder’s ability to bring and enforce legal actions in emerging market countries, or to obtain information needed to pursue or enforce such actions, may be limited and as a result such claims may be difficult or impossible to pursue. In the event of a default on any investments in foreign debt obligations, it may be more difficult for the Fund to obtain or to enforce a judgment against the issuers of such securities.

In addition, there may be little financial or accounting information available with respect to issuers of emerging market securities, and it may be difficult as a result to assess the value of an investment in such securities. Further, the Fund’s ability to participate fully in the smaller, less liquid emerging markets may be limited by the policy restricting its investments in illiquid securities. In addition, the taxation systems at the federal, regional and local levels in developing or emerging market countries may be less transparent and inconsistently enforced, and subject to sudden change. The Fund may be subject to emerging markets risk to the extent that it invests in securities of issuers or companies which are not considered to be from emerging markets, but which have customers, products, or transactions associated with emerging markets. Emerging market countries in which the Fund may invest include frontier market countries, which generally have smaller economies and even less developed capital markets than traditional developing markets, and, as a result, the risks of investing in developing market countries are magnified in frontier market countries. The magnification of risks are the result of: potential for extreme price volatility and illiquidity in frontier markets; government ownership or control of parts of private sector and of certain companies; trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which frontier market countries trade; and the relatively new and unsettled securities laws in many frontier market countries. Frontier market countries typically are located in the Asia-Pacific region, Central and Eastern Europe, the Middle East, Central and South America, and Africa.

Securities Lending

The Fund may lend its securities to approved borrowers. Any gain or loss on the market price of the securities loaned that might occur during the term of the loan would be for the account of the Fund. These loans cannot exceed one-third of the Fund’s total assets.

Approved borrowers are financial institutions that meet the Fund’s securities lending program requirements, which require that (i) the borrowers pledge and maintain with the Fund collateral consisting of cash, an irrevocable letter of credit issued by a bank, or securities issued or guaranteed by the U.S. Government having a value at all times of not less than 102% of the value of the securities loaned (on a “mark-to-market” basis); (ii) the loan be made subject to termination by the Fund at any time; and (iii) the Fund receives reasonable interest on the loan. From time to time, the Fund may return a part of the interest earned on the investment of collateral received from securities loaned to the borrower and/or a third party that is unaffiliated with the Fund and that is acting as a finder.

To the extent the Fund engages in securities lending, there is the risk of a delay in recovering loaned securities. If the Fund is unable to recover a security on loan, the Fund may use the collateral to purchase a replacement security in the market. There is a risk that the value of the collateral could be insufficient to cover the cost of the replacement security, resulting in a loss to the Fund.

The Adviser currently intends to invest the cash collateral in a cash management vehicle for which the Adviser serves as investment adviser, or in time deposits, which are managed by the Fund’s securities lending agent. An investment in a cash management vehicle is generally subject to the same risks that shareholders experience when investing in similarly structured vehicles, such as the potential for significant fluctuations in assets as a result of the purchase and redemption activity of the securities lending program, a decline in the value of the collateral, and possible liquidity issues. Such risks may delay the return of the cash collateral and cause the Fund to violate its agreement to return the cash collateral to a borrower in a

16

timely manner. As adviser to the Fund and the affiliated cash management vehicle in which a portion of the cash collateral is invested, the Adviser has an inherent conflict of interest as a result of its fiduciary duties to both the Fund and the affiliated cash management vehicle. Additionally, the Adviser receives an investment advisory fee for managing the affiliated cash management vehicle and therefore may have an incentive to allocate collateral to the affiliated cash management vehicle, rather than to other collateral management options for which the Adviser does not receive compensation.

Short Sales

The Fund may engage in short sales through short sales of stocks, futures, written calls, structured products, and through various types of derivatives. In a short sale transaction, the Fund sells a security it does not own to a purchaser at a specified price. To complete a short sale, the Fund must: (i) borrow the security to deliver it to the purchaser and (ii) buy that same security in the market to return it to the lender.

The Fund may incur a loss as a result of the short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security, and the Fund may realize a gain if the security declines in price between those same dates. Although the Fund’s potential for gain as a result of a short sale is limited to the price at which it sold the security short less the cost of borrowing the security, the potential for loss is theoretically unlimited because there is no upper limit to the cost of replacing the borrowed security. To borrow the security, the Fund may also be required to pay a premium, which would increase the cost of the security sold.

The Fund may not always be able to close out a short position at a particular time or at an acceptable price. A lender may request, or market conditions may dictate, that the borrowed securities be returned to the lender on short notice, and the Fund may have to buy the borrowed securities at an unfavorable price. If this occurs at a time when other short sellers of the same security also want to close out their positions, a “short squeeze” can occur, which means that the demand is greater than supply for the security sold short. If a short squeeze occurs, it is more likely that the Fund will have to cover its short sale at an unfavorable price and potentially reduce or eliminate any gain, or cause a loss, as a result of the short sale.

Short Sales Against the Box

The Fund may engage in “short sales against the box” and options for hedging purposes. This technique involves either selling short a security that the Fund owns, or has the right to obtain (equivalent in kind or amount to the securities sold short), for delivery at a specified date in the future. If the Fund enters into a short sale “against the box”, it will be required to set aside securities equivalent in kind and amount to the securities sold short (or securities convertible or exchangeable into such securities) and will be required to hold such securities while the short sale is outstanding. The Fund does not immediately deliver from its holdings the securities sold short and receives proceeds from the short sale only when it delivers the securities to the lender. If the price of the security has declined at the time the Fund is required to deliver the security, the Fund will benefit from the difference in the price. If the price of a security has increased, the Fund will be required to pay the difference.

Special Purpose Acquisition Companies

The Fund may invest in securities issued by special purpose acquisition companies (“SPACs”) or similar entities that pool funds to seek potential acquisition opportunities. Unless and until an acquisition is completed, a SPAC typically invests its assets (less a portion retained to cover expenses) in U.S. Government securities, money market fund securities, and cash. If an acquisition that meets the requirements for the SPAC is not completed within a pre-established period of time, the invested funds are returned to the SPAC’s shareholders. Because SPACs and similar entities are in essence blank check companies without an operating history or ongoing business other than seeking acquisitions, the value of a SPAC’s securities is particularly dependent on the ability of the SPAC’s management to timely identify and complete a profitable acquisition. Some SPACs may pursue acquisitions only within certain industries or regions, which may increase the volatility of their prices. To the extent the SPAC is invested in cash or similar securities while awaiting an acquisition opportunity, the Fund’s ability to meet its investment objective may be negatively impacted. In addition, SPACs, which are typically traded in the over-the-counter market, may be considered illiquid and/or be subject to restrictions on resale.

U.S. Government Securities

The 1940 Act defines U.S. Government securities to include securities issued or guaranteed by the U.S. Government, its agencies, and its instrumentalities. U.S. Government securities may also include repurchase agreements collateralized by and municipal securities escrowed with or refunded with U.S. Government securities.

17

U.S. Government securities in which the Fund may invest include U.S. Treasury securities, including Treasury Inflation-Protected Securities, Treasury bills, notes, and bonds, and obligations issued or guaranteed by U.S. Government agencies and instrumentalities that are backed by the full faith and credit of the U.S. Government. In addition, U.S. Government securities in which the Fund may invest include securities backed only by the rights of the issuers to borrow from the U.S. Treasury, such as those issued by the members of the Federal Farm Credit System, Federal Intermediate Credit Banks, Tennessee Valley Authority, and Freddie Mac. Securities issued by Fannie Mae, the Federal Home Loan Banks, and the Student Loan Marketing Association (“Sallie Mae”) are supported by the discretionary authority of the U.S. Government to purchase the obligations. There is no guarantee that the U.S. Government will support securities not backed by its full faith and credit. They may involve more risk than securities backed by the full faith and credit of the U.S. Government because the Fund must look principally to the agency or instrumentality issuing or guaranteeing the securities for repayment and may not be able to assert a claim against the United States if the agency or instrumentality does not meet its commitment.

Because of the rising U.S. Government debt burden, it is possible that the U.S. Government may not be able to meet its financial obligations or that securities issued or backed by the U.S. Government may experience credit downgrades. Such a credit event may adversely affect the financial markets.

The portfolio turnover rate of the Fund is calculated by dividing the lesser of purchases or sales of portfolio securities (exclusive of purchases or sales of U.S. Government securities and all other securities whose maturities at the time of acquisition were one year or less) by the monthly average of the value of the portfolio securities owned by the Fund during the year. Proceeds from short sales and assets used to cover short positions undertaken are included in the amounts of securities sold and purchased, respectively, during the fiscal year. A 100% portfolio turnover rate would occur, for example, if all of the securities held by the Fund were replaced once during the fiscal year. The Fund cannot accurately predict its turnover rate. Variations in portfolio turnover rates shown may be due to market conditions, changes in the size of the Fund, fluctuating volume of shareholder purchase and redemption orders, the nature of the Fund’s investments, the investment style and/or outlook of portfolio management, or due to a restructuring of the Fund’s portfolio as a result of a change in portfolio management. The Fund’s portfolio turnover rate may be higher when the Fund finds it necessary to significantly change its portfolio to adopt a temporary defensive position or respond to economic or market events. Higher levels of portfolio turnover may result in higher costs for brokerage commissions, dealer mark-ups, and other transaction costs, and may also result in taxable capital gains. Higher costs associated with increased portfolio turnover may offset gains in Fund performance.

The following table summarizes the portfolio turnover rates for the Fund for the period from the commencement of operations on February 4, 2025 through October 31, 2025.

The ETF Holdings Disclosure Policies and Procedures adopted by the Adviser and the series of the Trust (the “Janus Henderson funds”) are designed to ensure that the Fund’s portfolio holdings information is disclosed in a manner that (i) is consistent with applicable legal requirements and in the best interest of the Fund’s shareholders; (ii) does not put the interests of the Adviser, ALPS Distributors, Inc. (“ALPS” or the “Distributor”), or any affiliated person of the Adviser or ALPS, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. Item (iii) above does not preclude the provision of portfolio holdings information not available to other current or prospective Fund shareholders to certain Entities to the extent such information is necessary to facilitate Creation Unit transactions. These “Entities” are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized

18

Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements and market makers and other institutional market participants and entities that provide information for transactional services.

Disclosure of Portfolio Holdings in Accordance with Regulatory Requirements. Each business day, the Fund’s portfolio holdings information is provided to the Fund’s custodian or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. This information typically reflects the Fund’s anticipated holdings on the following business day. In addition, on each business day before commencement of trading in shares on the Listing Exchange, the Fund will disclose on janushenderson.com/info the identities and quantities of each portfolio position held by the Fund that will form the basis for the Fund’s next calculation of the NAV.

Disclosure of Portfolio Holdings as Required by Applicable Law. The Fund’s portfolio holdings will be available semiannually and annually in Form N-CSR and, after the first and third fiscal quarters, in Form N-PORT. Information reported in Form N-CSR and in Form N-PORT will be made publicly available within 70 and 60 days, respectively, after the end of each fiscal quarter. The Fund’s Form N-CSR and Form N-PORT filings will be available on the SEC’s website at http://www.sec.gov.

Daily access to information concerning the Fund’s portfolio holdings is permitted (i) to certain personnel of those service providers that are involved in portfolio management and in providing administrative, operational, risk management, or other support to portfolio management; and (ii) to other personnel of the Adviser, ALPS and its affiliates, and the administrator, custodian, and fund accountant who deal directly with, or assist in, functions related to investment management, distribution, administration, custody, securities lending, and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with federal securities laws and regulations thereunder.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Fund in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Fund, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

Nonpublic portfolio holdings information may be disclosed to certain third parties upon a good faith determination made by the head of the applicable investment unit or a delegate in consultation with the Fund’s Chief Compliance Officer or a designee, that the Fund has a legitimate business purpose for such disclosure and the recipient agrees to maintain confidentiality. The Chief Compliance Officer reports to the Fund’s Trustees regarding material compliance matters with respect to the portfolio holdings disclosure policies and procedures.

Under extraordinary circumstances, the head of the applicable investment unit or a delegate, in consultation with the Fund’s Chief Compliance Officer, has the authority to waive one or more provisions of, or make exceptions to, the ETF Holdings Disclosure Policies and Procedures when in the best interest of the Fund and when such waiver or exception is consistent with federal securities laws and applicable fiduciary duties.

Investment Adviser

As stated in the Prospectus, the Fund has an Investment Advisory Agreement (“Advisory Agreement”) with Janus Henderson Investors US LLC (the “Adviser”), 151 Detroit Street, Denver, Colorado 80206-4805. The Adviser is an indirect wholly-owned subsidiary of Janus Henderson Group plc (“JHG”), a global asset manager. Janus Henderson US (Holdings) Inc., the direct parent of the Adviser, completed a strategic combination with Henderson Group plc on May 30, 2017 to form JHG, doing business as Janus Henderson Investors.

The Fund’s Advisory Agreement continues in effect for an initial term of two years and from year to year thereafter so long as such continuance is approved at least annually by the vote of a majority of the Trustees who are not parties to the Advisory Agreement or “interested persons” (as defined by the 1940 Act) of any such party (the “Independent Trustees”), and by either the Trustees or the affirmative vote of a majority of the outstanding voting securities of the Fund. The Advisory Agreement: (i) may be terminated, without the payment of any penalty, by the Trustees, or the vote of at least a majority of the outstanding voting securities of the Fund, or the Adviser, on at least 60 days’ advance written notice; (ii) terminates automatically in the event of its assignment; and (iii) generally, may not be amended without the approval by vote of a majority of the Trustees of the Fund, including a majority of the Independent Trustees, and, to the extent required by the 1940 Act, the affirmative vote of a majority of the outstanding voting securities of the Fund.

The Advisory Agreement provides that the Adviser will furnish continuous advice and recommendations concerning the Fund’s investments, provide office space for the Fund and certain other advisory-related services. Pursuant to the Advisory Agreement, under the unitary fee structure, the Fund pays the Adviser a “Management Fee” in return for providing certain investment advisory, supervisory, and administrative services to the Fund. The fee structure is designed to pay substantially all of the Fund’s expenses. However, the Fund bears other expenses which are not covered under the Management Fee, such as distribution fees (if any), brokerage expenses or commissions, interest, dividends, taxes, litigation expenses, acquired fund fees and expenses (if any), and extraordinary expenses.

On December 22, 2025, JHG, Trian Fund Management, L.P. and its affiliated funds (“Trian”), and General Catalyst Group Management, LLC and its affiliated funds (“General Catalyst”) announced that they have entered into a definitive agreement under which Janus Henderson will be acquired by Trian and General Catalyst (the “Transaction”). The Transaction is expected to close in 2026, subject to customary closing conditions, including requisite regulatory approvals, client consents, and approval by Janus Henderson’s shareholders.

The closing of the Transaction will be deemed to be an “assignment” (as defined in the 1940 Act) of the advisory agreement between the Fund and the Adviser. As a result, the closing of the Transaction will cause the advisory agreement to terminate automatically in accordance with its terms. On February 11, 2026, the Trustees approved a new advisory agreement with the Adviser. The new agreement will be presented to the Fund’s shareholders for approval, and, if so approved by shareholders, will take effect upon the closing of the Transaction or such later time as shareholder approval is obtained.

The Adviser has received an exemptive order from the SEC that permits the Adviser, subject to the approval of the Trustees, to appoint or replace certain subadvisers to manage all or a portion of the Fund’s assets and enter into, amend, or terminate a subadvisory agreement with certain subadvisers without obtaining shareholder approval (a “manager-of-managers structure”). The manager-of-managers structure applies to subadvisers that are not affiliated with the Trust or the Adviser (“non-affiliated subadvisers”), as well as any subadviser that is an indirect or direct “wholly-owned subsidiary” (as such term is defined by the 1940 Act) of the Adviser or of another company that, indirectly or directly, wholly owns the Adviser (collectively, “wholly-owned subadvisers”).

Pursuant to the order, the Adviser, with the approval of the Trustees, has the discretion to terminate any subadviser and allocate and reallocate the Fund’s assets among the Adviser and any other non-affiliated subadvisers or wholly-owned subadvisers (including terminating a non-affiliated subadviser and replacing it with a wholly-owned subadviser). To the extent that the Fund’s assets are allocated to one or more subadvisers, the Adviser, subject to oversight and supervision by the Trustees, would have responsibility to oversee such subadviser to the Fund and to recommend for approval by the Trustees, the hiring, termination, and replacement of a subadviser for the Fund. The order also permits the Fund to disclose

20

subadvisers’ fees only in the aggregate. In the event that the Adviser hires a new subadviser pursuant to the manager-of-managers structure, the affected Janus Henderson fund would provide shareholders with information about the subadviser and subadvisory agreement within 90 days.

The Trustees and the initial shareholder of the Fund have approved the use of a manager-of-managers structure for the Fund.

The Adviser also provides certain administration services necessary for the operation of the Fund, including, but not limited to, the preparation of prospectuses.

The Fund pays a monthly Management Fee to the Adviser for its services. The fee is based on the daily net assets of the Fund and is calculated at the following annual rate.

The following table summarizes the Management Fees paid by the Fund for the period from the commencement of operations on February 4, 2025 through October 31, 2025.

The Adviser has contractually agreed to waive and/or reimburse a portion of the Fund’s management fee in an amount equal to the management fee it earns as an investment adviser to any affiliated ETFs in which the Fund invests. Pursuant to this agreement, the waiver amount is equal to the amount of the Fund’s assets invested in the affiliated ETF, multiplied by an amount equal to the current daily unitary management fee of the affiliated ETF less certain asset-based operating fees and expenses incurred on a per-fund basis and paid by the Adviser with respect to the affiliated ETF (including, but not limited to custody, sub-administration and transfer agency fees, and fees paid to the distributor). The fee waiver agreement will remain in effect at least until February 28, 2028. The Adviser will not recover amounts previously waived or reimbursed that are related to investments in affiliated ETFs. The fee waiver agreement may be modified or terminated prior to this date only at the discretion of the Trustees.

From their own assets, the Adviser or its affiliates pay selected brokerage firms or other financial intermediaries for making Janus Henderson funds available to their clients or for distribution, marketing, promotional, data, or related services and/or for providing transaction processing and other shareholder or administrative services. The Adviser or its affiliates also make payments to one or more intermediaries for information about transactions and holdings in the funds, such as the amount of fund shares purchased, sold or held through the intermediary and or its salespersons, the intermediary platform(s) on which shares are transacted and other information related to the funds. The Adviser or its affiliates make payments to one or more intermediaries for operational and/or platform set-up and maintenance fees on a per fund basis, often referred to as Committee on Uniform Security Identification Procedures (“CUSIP”) fees. Payments made by the Adviser and its affiliates to intermediaries may eliminate or reduce trading commissions that the intermediary would otherwise charge its customers or its salespersons in connection with the purchase or sale of certain funds. Payment by the Adviser or its affiliates to eliminate or reduce a trading commission creates an incentive for salespersons of the intermediary to sell the Janus Henderson funds over other funds for which a commission would be charged. The amount of these payments is determined from time to time by the Adviser or its affiliates, may be substantial, and may differ for different intermediaries. The Adviser may determine to make payments based on any number of factors or metrics. For example, the Adviser may make payments at year-end and/or other intervals in a fixed amount, an amount based upon an intermediary’s services at defined levels, an amount based upon the total assets represented by funds subject to arrangements with the intermediary, an amount based on the intermediary’s net sales of one or more funds in a year or other period, or a fee based on the management fee received by the Adviser, any

21

of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. Payments based primarily on sales create an incentive to make new sales of shares, while payments based on assets create an incentive to retain previously sold shares. The Adviser currently maintains asset-based agreements with certain intermediaries on behalf of the Trust. Other factors may include, but are not limited to, the distribution capabilities of the intermediary, the overall quality of the relationship, expected gross and/or net sales generated by the relationship, disposition and retention rates of assets held through the intermediary, the willingness to cooperate with the Adviser’s marketing efforts, access to sales personnel, and the anticipated profitability of sales through the institutional relationship. These factors and their weightings varies from one intermediary to another and may change from time to time. As of February 4, 2026, the broker-dealer firms with which the Adviser or its affiliates have agreements or are currently negotiating agreements to make payments out of their own assets related to the acquisition or retention of certain Janus Henderson ETFs are E*Trade Securities LLC; Fidelity Brokerage Services LLC; The Guardian Life Insurance Company of America; LPL Financial LLC; Morgan Stanley Smith Barney, LLC; National Financial Services LLC; Park Avenue Securities LLC; Pershing LLC; Raymond James Financial Services, Inc.; and Raymond James & Associates, Inc. Any additions, modifications, or deletions to the broker-dealer firms identified that have occurred since that date are not reflected.

With respect to non-exchange-traded Janus Henderson funds, the Adviser or its affiliates may pay fees, from their own assets, to selected brokerage firms, banks, financial advisors, retirement plan service providers, and other financial intermediaries that sell the Janus Henderson funds for distribution, marketing, promotional, or related services, and/or for providing recordkeeping, subaccounting, transaction processing, and other shareholder or administrative services (including payments for processing transactions via NSCC or other means), and the CUSIP and fund setup fees in connection with investments in the Janus Henderson funds. These fees are in addition to any fees that may be paid by the Janus Henderson funds for these types of services or other services. Shareholders investing through an intermediary should consider whether such arrangements exist when evaluating any recommendations from an intermediary.

In addition, the Adviser or its affiliates may also share certain marketing expenses with selected intermediaries, or pay for or sponsor informational meetings, seminars, client awareness events, and support for marketing materials, sales reporting, or business building programs for such intermediaries to raise awareness of the Janus Henderson funds. The Adviser or its affiliates may also pay intermediaries for the development of technology platforms and reporting systems. The Adviser or its affiliates make payments to participate in selected intermediary marketing support programs which may provide the Adviser or its affiliates with one or more of the following benefits: attendance at sales conferences, participation in meetings or training sessions, access to or information about intermediary personnel, use of an intermediary’s marketing and communication infrastructure, fund analysis tools, data, business planning and strategy sessions with intermediary personnel, information on industry- or platform-specific developments, trends and service providers, and other marketing-related services. Such payments may be in addition to, or in lieu of, the payments described above. These payments are intended to promote the sales of Janus Henderson funds and to reimburse financial intermediaries, directly or indirectly, for the costs that they or their salespersons incur in connection with educational seminars, meetings, and training efforts about the Janus Henderson funds to enable the intermediaries and their salespersons to make suitable recommendations, provide useful services, and maintain the necessary infrastructure to make the Janus Henderson funds available to their customers.

The receipt of (or prospect of receiving) payments, reimbursements, and other forms of compensation described above may provide a financial intermediary and its salespersons with an incentive to favor sales of Janus Henderson funds’ shares over sales of other funds (or non-investment company investments), with respect to which the financial intermediary does not receive such payments or receives them in a lower amount. The receipt of these payments may cause certain financial intermediaries to elevate the prominence of the Janus Henderson funds within such financial intermediary’s organization by, for example, placement on a list of preferred or recommended funds and/or the provision of preferential or enhanced opportunities to promote the Janus Henderson funds in various ways within such financial intermediary’s organization.

From time to time, certain financial intermediaries approach the Adviser to request that the Adviser make contributions to certain charitable organizations. In these cases, the Adviser’s contribution may result in the financial intermediary, or its salespersons, recommending Janus Henderson funds over other funds (or non-mutual fund investments).

The payment arrangements described above will not change the price an investor pays for shares nor the amount that a Janus Henderson fund receives to invest on behalf of the investor. You should consider whether such arrangements exist when evaluating any recommendations from an intermediary to purchase or sell shares of Janus Henderson funds. Please contact your financial intermediary or plan sponsor for details on such arrangements.

The Adviser has adopted procedures (including trade allocation procedures described in the “Portfolio Transactions and Brokerage” section of this SAI) that it believes are reasonably designed to mitigate potential conflicts and risks. For example, the Adviser manages long and short portfolios. The simultaneous management of long and short portfolios creates potential conflicts of interest in fund management and creates potential risks such as the risk that short sale activity could adversely affect the market value of long positions in one or more Janus Henderson funds (and vice versa), the risk arising from the sequential orders in long and short positions, and the risks associated with the trade desk receiving opposing orders in the same security at the same time.

To mitigate this potential conflict, the Adviser has procedures that prohibit portfolio management from executing a short sale on a security held long in any other portfolio that he or she manages but is not held long in the account in which portfolio management is placing the short. Note this does not prohibit shorting against the box. The procedures also require approvals of the Adviser’s senior management in other situations that raise potential conflicts of interest, as well as periodic monitoring of long and short trading activity of the Janus Henderson funds and accounts.

The Fund and other funds advised by the Adviser or its affiliates may also transfer daily uninvested cash balances into one or more joint trading accounts. Assets in the joint trading accounts are invested in money market instruments and the proceeds are allocated to the participating funds on a pro rata basis.

Pursuant to the provisions of the 1940 Act, Janus Henderson funds may participate in an affiliated or non-affiliated cash sweep program. In the cash sweep program, uninvested cash balances of Janus Henderson funds may be used to purchase shares of affiliated or non-affiliated money market funds or cash management pooled investment vehicles that operate pursuant to the provisions of the 1940 Act that govern the operation of money market funds. All Janus Henderson funds are eligible to participate in the cash sweep program (the “Investing Funds”). The Adviser has an inherent conflict of interest because of its fiduciary duties to the affiliated money market funds or cash management pooled investment vehicles and the Investing Funds. In addition, the Adviser receives an investment advisory fee for managing affiliated money market funds and the cash management vehicle used for its securities lending program, but it may not receive a fee for managing certain other affiliated cash management vehicles, and therefore may have an incentive to allocate preferred investment opportunities to investment vehicles for which it is receiving a fee.

Each account managed by the Adviser has its own investment objective and policies and is managed accordingly by the respective portfolio management. As a result, from time to time, two or more different managed accounts may pursue divergent investment strategies with respect to investments or categories of investments.

The officers and Trustees of the Janus Henderson funds may also serve as officers and Trustees of ETFs, hedge funds, private funds, and other Janus Henderson financial products managed by the Adviser. Conflicts may arise as the officers and Trustees seek to fulfill their fiduciary responsibilities to both the Fund and other Janus Henderson financial products. The Trustees intend to address any such conflicts as deemed appropriate.

ALPS Distributors, Inc.’s Code of Ethics

Pursuant to Rule 17j-1 under the 1940 Act, the Trustees have approved a Code of Ethics adopted by ALPS The Code of Ethics is intended to ensure that the interests of shareholders and other clients are placed ahead of any personal interest, that no undue personal benefit is obtained from the person’s employment activities and that actual and potential conflicts of interest are avoided.

The Code of Ethics applies to the personal investing activities of ALPS Distributors, Inc. (“Access Persons”). Rule 17j-1 and the Code of Ethics are designed to prevent unlawful practices in connection with the purchase or sale of securities by Access Persons. Under the Code of Ethics, Access Persons are permitted to engage in personal securities transactions, but are required to report their personal securities transactions for monitoring purposes. The Code of Ethics permits personnel subject to the Code to invest in securities subject to certain limitations, including securities that may be purchased or held by the Fund. In addition, certain Access Persons are required to obtain approval before investing in initial public offerings or private placements. The Code of Ethics is on file with and available from the SEC through the SEC website at http://www.sec.gov.

Janus Henderson Personal Code of Ethics

The Adviser currently has in place the Personal Code of Ethics, which is comprised of the Personal Account Dealing Policy, the Gifts, Entertainment and Other Benefits Received Policy, the Outside Business Activities Policy, and the Political Activities Policy. The Personal Code of Ethics is designed to ensure the Adviser’s personnel: (i) observe applicable legal (including compliance with applicable federal securities laws) and ethical standards in the performance of their duties; (ii) at all times place the interests of the Fund’s shareholders first; (iii) disclose all actual or potential conflicts; (iv) adhere to the highest standards of loyalty, candor, and care in all matters relating to the Fund’s shareholders; (v) conduct all personal trading, including transactions in the Fund and other securities, consistent with the Personal Code of Ethics and in such a manner as to avoid any actual or potential conflict of interest or any abuse of their position of trust and responsibility; and (vi) refrain from using any material nonpublic information in securities trading. The Personal Code of Ethics is on file with and available from the SEC through the SEC website at http://www.sec.gov.

Under the Personal Account Dealing Policy, all the Adviser personnel, as well as the Trustees and Officers of the Fund, are required to conduct their personal investment activities in a manner that the Adviser believes is not detrimental to the Fund. In addition, the Adviser’s personnel are not permitted to transact in securities held by the Fund for their personal accounts except under circumstances specified in the Personal Account Dealing Policy. All personnel of the Adviser, and the Fund, as well as certain other designated employees deemed to have access to current trading information, are required to pre-clear all transactions in securities not otherwise exempt. Requests for trading authorization will be denied when, among other reasons, the proposed personal transaction would be contrary to the provisions of the Personal Account Dealing Policy.

In addition to the pre-clearance requirement described above, the Personal Account Dealing Policy subjects such personnel to various trading restrictions and reporting obligations. All reportable transactions are reviewed for compliance with the Personal Account Dealing Policy and under certain circumstances the Adviser personnel may be required to forfeit profits made from personal trading.

The Trustees of the Trust have delegated to the Adviser the authority to vote all proxies relating to the Fund’s portfolio securities in accordance with the Adviser’s own policies and procedures. The Adviser’s proxy voting policies and procedures, including specific voting guidelines, are included in Appendix A of this SAI and are also available at janushenderson.com/proxyvoting.

The Adviser or its affiliates will publicly disclose vote reporting in line with local market requirements or practices and/or where, in the Adviser’s view, it is appropriate. The Fund’s proxy voting record for the one-year period ending each June 30th is available, free of charge, upon request, by calling 1-800-525-1093, through janushenderson.com/proxyvoting, or from the SEC through the SEC website at http://www.sec.gov.

Custodian, Transfer Agent, and Certain Affiliations

JPMorgan Chase Bank, N.A. (“JP Morgan” or the “Custodian”), 383 Madison Avenue, New York, NY 10179 is the custodian of the domestic securities and cash of the Fund. JP Morgan is the designated Foreign Custody Manager (as the term is defined in Rule 17f-5 under the 1940 Act) of the Fund’s securities and cash held outside the United States. The Fund’s Trustees have delegated to JP Morgan certain responsibilities for such assets, as permitted by Rule 17f-5. JP Morgan and the foreign subcustodians selected by it hold the Fund’s assets in safekeeping and collect and remit the income thereon, subject to the instructions of the Fund. JP Morgan also serves as transfer agent for the shares of the Fund (“Transfer Agent”).

JP Morgan also provides certain fund administration services to the Fund, including services related to the Fund’s accounting, including calculating the daily NAV, audit, tax, and reporting obligations, pursuant to an Agreement with the Adviser, on behalf of the Fund. The Adviser may cancel this Agreement at any time with 90 days’ notice. As compensation for such services, the Adviser pays JP Morgan a fee based on a percentage of the Fund’s assets, and a flat fee, for certain services. The Adviser serves as administrator to the Fund, providing oversight and coordination of the Fund’s service providers, recordkeeping and other administrative services. The Adviser does not receive any additional compensation, beyond the unitary fee, for serving as administrator. Pursuant to agreements with the Fund, J.P. Morgan Securities LLC, an affiliate of JP Morgan, may execute portfolio transactions for the Fund, including but not limited to, in connection with cash in lieu transactions (as described under Fund Deposit and Redemption of Creation Units).

The following table summarizes the fees received by JP Morgan for custodian, transfer agent and sub-administrative services from commencement of operations on February 4, 2025 through October 31, 2025.

Portfolio Transactions and Brokerage

The Adviser, or its affiliates, acting pursuant to the Global Execution Agreement mentioned below, initiate all portfolio transactions of the Fund, solely upon the direction of the relevant portfolio management. The Adviser is party to a Global Execution Agreement with certain Janus Henderson affiliates (the “Trading Affiliates”) that allows trades in foreign markets to be executed by personnel in the relevant market through such Trading Affiliates. Personnel of the Trading Affiliates providing trade execution services are subject to brokerage policies and procedures and oversight by Janus Henderson Investors’ Front Offices Governance and Risk Committee. As used in this Portfolio Transactions and Brokerage section, the term “Adviser” also includes its Trading Affiliates.

The Adviser selects broker-dealers for the Fund as part of its discretionary responsibilities under the Advisory Agreement and broker selection is determined by the Adviser’s duty to seek best execution. Brokers may include Authorized Participants and/or market makers for the Fund. Janus Henderson’s Best Execution Committee will periodically review the quality of execution that the Adviser receives from broker-dealers and the Adviser will continually evaluate the effectiveness of the executing brokers and trading tools utilized. The Adviser does not consider a broker-dealer’s sale of shares of the Fund or gifts and entertainment received from registered representatives of broker-dealers when choosing a broker-dealer to effect transactions.

The Adviser has a duty to seek to obtain “best execution” for its portfolio transactions by reasonably seeking to obtain the best possible result under the circumstances. The Adviser considers a number of factors including but not limited to: an understanding of prices of securities currently available and commission rates and other costs associated with various trading tools, channels and venues; the nature, liquidity, size and type of the security being traded and the character of the markets in which the security will be purchased or sold; the activity, existing and expected, in the market for the particular security; the potential impact of the trade in such market and the desired timing or urgency of the trade pursuant to the investment decision; any portfolio restrictions associated with asset types; the ability of a broker-dealer to maintain confidentiality, including trade anonymity; the quality of the execution, clearance, and settlement services of a broker-dealer; the financial stability of the broker-dealer and the existence of actual or apparent operational problems of the broker-dealer; principal commitment by the broker-dealer to facilitate the transaction; and for accounts that do not utilize a research charge collection agreement, as discussed below, the research services provided by a broker-dealer.

As applicable, the Fund generally buys and sells fixed-income securities in principal and agency transactions in which no brokerage commissions are paid. However, the Fund may engage an agent and pay commissions for such transactions if the Adviser believes that the net result of the transaction to the Fund will be no less favorable than that of contemporaneously available principal transactions. The implied cost of executing fixed-income securities transactions for the Fund primarily will consist of bid-offer spreads at which brokers will transact. The spread is the difference between the prices at which the broker is willing to purchase and sell the specific security at the time.

When the Fund purchases or sells a security in the over-the-counter market, the transaction takes place directly with a principal market-maker, without the use of a broker, except in those circumstances where, in the opinion of the Adviser, better prices and executions will be achieved through the use of a broker.

The Adviser unbundles equity commissions globally. More specifically, the Adviser defines an execution commission component (“ECC”) and a research commission component (“RCC”). The ECC is standard across all brokers by region and broker class. Generally, the ECC is not negotiated on an order-by-order basis, but is determined by an established rate card that is reviewed by the Janus Henderson Best Execution Committee. Those rates are established to be competitive with industry standards and aligned with the service level the Adviser expects from brokers. With respect to the RCC, consistent with its best execution obligation for accounts that do not utilize an RCCA (as defined below), and as permitted by Section 28(e) of the Securities Exchange Act of 1934, as amended, and subsequent SEC guidance and no-action relief, the Adviser may place portfolio transactions with a broker-dealer for a higher commission than another broker-dealer would have charged for effecting that transaction if the Adviser determines, in good faith, that the commission is reasonable in relation to the value of the brokerage and/or research services provided by such broker-dealer or provided by third parties viewed in terms of either that particular transaction or of the overall responsibilities of the Adviser with respect to all client accounts. Funds that utilize RCCAs are prohibited from using research charges for brokerage services and are subject to additional restrictions on what constitutes eligible research as provided by the Markets in Financial Instruments Directive II (“MiFID II”) and Financial Conduct Authority (“FCA”) regulations.

26

The Adviser has client commission agreements (“CCAs”) and, for certain funds, RCC Agreements (“RCCAs”) with certain broker-dealers. These agreements allow the Adviser to instruct broker-dealers to pool commissions or research charges, respectively, generated from equity security orders executed at that broker-dealer. RCCAs are utilized for accounts for which Janus Henderson is subject to MiFID II and instead of using a portion of the commission for research, an additional research charge is added to the execution commission for equity transactions. Pursuant to these agreements, the broker-dealer retains the execution component of the brokerage commission as compensation for execution services and segregates the other portion of the commission (or additional research charge for RCCAs) for research services. Such commissions (and charges) are then used, upon the Adviser’s direction, to pay such broker-dealers for such broker-dealers’ proprietary research or to pay third parties that provide the Adviser with brokerage or research services, as permitted under Section 28(e), and for RCCAs, as permitted under MiFID II and FCA regulation. All portfolio transactions directed to these broker-dealers are subject to the Adviser’s best execution obligations.

The Adviser establishes a research budget annually for each investment strategy, and the research portion of the commission (or additional research charge for RCCAs) is collected until the Fund’s pro rata portion of the research budget for its investment strategy is reached. Typically, it is expected that the Fund’s proportionate share of the budget for its strategy will be based on the amount of assets held in its account relative to overall assets in the strategy. Once the pro rata budget of any account within an investment strategy is reached, such account will transact at the execution only rate for the remainder of the applicable period. If the costs for external research or brokerage services for an investment strategy exceed the amount collected from accounts within that strategy, the Adviser or its affiliates may adjust the research portion of commissions (or research charges) up or down within such strategy, continue to acquire external research for such accounts using its own resources, or cease to purchase external research for such accounts until the next applicable period. If research commissions (or research charges) collected by accounts within an investment strategy exceed the research or brokerage services costs for such investment strategy, the Adviser may rebate the accounts within such strategy all or a portion of their pro rata portion of such excess (subject to de minimis amounts as determined by the Adviser) or (for CCAs only) rollover such amounts to be used for research during the next applicable period.

The Adviser oversees the consumption, valuation and appropriate remuneration of third-party investment research consumed by the Adviser. Research budgets are set annually based on the needs of each investment strategy and are not otherwise linked to the volume or value of transactions executed on behalf of any accounts within that strategy. Research budgets may be adjusted by the Adviser throughout the calendar year.

The Adviser intends that all client equity transactions will be included within its CCAs and RCCAs, except to the extent the Adviser manages a strategy in which portfolio management solely uses market data or in which portfolio management and the clients are located in Europe, the Middle East, or Asia, the Adviser may determine to pay for research for such strategies and/or accounts consistent with the methods available pursuant to MiFID II, including by use of an RCCA or Janus Henderson’s own resources. Therefore, whether and to what extent clients pay for research through commissions differs among clients. However, subject to applicable law, research may be used to service any or all clients, including clients that do not pay commissions to the broker-dealer relating to the CCA. As a result, clients that do not directly pay for research or pay for research to a lesser extent, including in connection with the establishment of research budgets (switching to execution only rates when research budgets are met), may be considered to disproportionately benefit from research payments of other clients.

The Adviser may receive statistical, research and other factual information or services from broker-dealers that it would otherwise have to pay for with cash, or use its own resources to produce, for no consideration other than the brokerage or underwriting commissions that they obtain from the Adviser’s execution of trades with the broker-dealers.

The Adviser may also use step-out or sponsorship transactions in order to receive research products and related services. In step-out or sponsorship transactions, the Adviser directs trades to a broker-dealer with the instruction that the broker-dealer execute the transaction, but direct all or a portion of the transaction or commission in favor of a second broker-dealer that provides such products and/or services. The second broker-dealer may clear and settle and receive commissions for the remaining portion.

The Adviser may also use broker sponsorship programs in order to pay for research. The Adviser may receive research from a sponsored broker but choose to execute with an executing agent on behalf of the sponsored broker. The executing agent executes the trade and then sends it to the sponsored broker for settlement. The Adviser pays the sponsored broker the commissions on the trade and the sponsored broker then pays the executing agent a predetermined fee.

27

The Adviser maintains prime brokerage arrangements to facilitate short sale transactions. A prime broker may provide services and products to the Adviser in connection with the short selling facilities and related services the prime broker provides. The Adviser typically uses technology and personalized client services, but additional services such as capital introduction, business consulting services and portfolio analytics may also be available from prime brokers.

For the fiscal year ended October 31, 2025, the total brokerage commissions paid by the Fund to brokers and dealers in transactions identified for execution primarily on the basis of research and other services provided to the Fund are summarized below.

The Adviser may have an incentive to use broker-dealers who offer the above services to effect transactions instead of other broker-dealers who do not provide such services, but who may execute transactions at a lower price. The Adviser does not guarantee any broker the placement of a predetermined amount of securities transactions in return for the research or brokerage services it provides. The Adviser does, however, have an internal procedure for allocation transactions in a manner consistent with its execution policy to brokers that it has identified as providing research or brokerage services. Any transactions with such brokers are always subject to the Adviser’s best execution obligations.

In order for client commissions to be used to pay for these services, the Adviser must determine that the services are permitted research or brokerage services under Section 28(e) or under FCA regulation, as applicable. Additionally, all broker-dealers and all vendors of research and/or brokerage services paid with client commissions will be approved pursuant to the Adviser’s policies and procedures. In instances when the above services may include components not eligible under Section 28(e) or FCA regulation, the Adviser makes a reasonable allocation of the cost of the research and/or brokerage services according to its use and all non-eligible research and/or brokerage services are separately invoiced and paid for with cash from the Adviser and not with client commissions.

Research received from broker-dealers is supplemental to the Adviser’s own research efforts. The brokerage and research products and services furnished by broker-dealers may be used in servicing any or all of the Adviser’s clients and may not necessarily be used by the Adviser in connection with the accounts that actually paid commissions, nor in proportion to the amount of commissions paid by accounts, to the broker-dealer providing the products and services.

The Adviser may engage in “cross trades” whereby the Adviser causes its clients or accounts to engage in a purchase and sale of a security with each other. The Adviser may engage in cross trades where it determines such transaction is in the best interests of both accounts and consistent with the Adviser’s best execution obligations. Although the use of cross trades may be beneficial to clients, it also creates opportunities for conflicts of interest to adversely affect clients. For instance, the Adviser could prefer one account over the other in determining price or otherwise executing a cross trade due to the existence of a more favorable fee structure or proprietary interest in one account. To address these potential conflicts, the Adviser has adopted policies and procedures which require that all cross trades are effected at a readily available fair market price, which may be based on independent dealer bids or quotes depending on the type of security. In addition, cross trades involving a registered investment company must be consistent with Rule 17a-7 under the 1940 Act. The Adviser may execute cross trades among any eligible funds and accounts managed by the Adviser or its affiliates. The Adviser does not permit cross trades with the Fund for fixed-income securities, with accounts subject to the Employee Retirement Income Security Act of 1974 or where prohibited by client restrictions.

The Adviser makes investment decisions for each of its clients, including proprietary accounts, independently from those of any other account that is or may become managed by the Adviser or its affiliates. Because the Adviser generally invests in similar strategies for clients, numerous clients could have similar investment objectives and thus, similar portfolios. As a result, the Adviser may be trading the same security for multiple clients at the same time. In order to seek efficiencies that may be available for larger transactions, or help allocate execution fills and prices fairly, the Adviser may aggregate the orders for its clients for execution in circumstances where the Adviser determines that the investment is eligible and appropriate for each participating account. Clients participating in an aggregated trade are generally charged the same price and execution rate or execution portion of the commission except in circumstances where doing otherwise is deemed fair and consistent with applicable law. Instances can occur in which not all clients are charged a research portion (or the same research portion) of the commission in an aggregated trade, including where clients have a different research rate, have already met the research budget established by the Adviser or are subject to regulatory or other restrictions on the use of client commissions to pay for research services and may transact at lower commissions or execution only rates. In addition to, or instead of,

28

aggregating orders of accounts that would be trading the same security at the same time, the Adviser may average the price of the transactions of these accounts and allocate trades to each account in accordance with the Adviser’s allocation procedures. Pursuant to these procedures, partial fills will be allocated pro rata under procedures adopted by Janus Henderson. The Adviser seeks to allocate the opportunity to purchase or sell a security or other investment among accounts on an equitable basis by taking into consideration certain factors. These factors include, but are not limited to: size of the portfolio, concentration of holdings, investment objectives and guidelines, position weightings, duration targets, consistency of portfolio characteristics across similar accounts, purchase costs, issuer restrictions, price targets and cash availability. Due to such factors, the Adviser cannot assure equality of allocations among all of its accounts, nor can it assure that the opportunity to purchase or sell a security or other investment will be proportionally allocated among accounts according to any particular or predetermined standards or criteria which could cause performance divergence from similar accounts. In some cases, these allocation procedures may adversely affect the price paid or received by an account or the size of the position obtained or liquidated for an account. In others, however, the accounts’ ability to participate in volume transactions may produce better executions and prices for the accounts. The Adviser may adjust allocations to eliminate fractional shares or odd lots, or to account for minimum trade size requirements and has the discretion to deviate from its allocation procedures in certain circumstances.

Funds may from time to time participate in initial public offerings (“IPOs”) or other types of limited offerings such as secondary placements of common stock, private equity offerings, or other private placement offerings. To the extent that a fund, such as a new fund, has only affiliated shareholders, such as portfolio management or an adviser, and the fund wishes to participate in an IPO, those shareholders may be perceived as receiving a benefit and, as a result, may have a conflict with management of the fund and thus may not be eligible to participate in the offering. Funds may also, from time to time, participate as an anchor or Cornerstone Investor in an IPO. A Cornerstone Investor agrees, prior to a company’s IPO, to acquire a certain dollar amount of the IPO securities. Such agreement provides the Cornerstone Investor with an agreed and known allocation in the IPO. Shares allocated to the Cornerstone Investor in such IPOs may be restricted from trading for up to six months post the IPO and participation by any Adviser account as a Cornerstone Investor could preclude any other account from participating in the IPO as a non-Cornerstone Investor. The Adviser utilizes a dual book IPO indication process. More specifically, in order to provide issuers with a level of flexibility to address the diverse styles, needs, and relationships of our global investment teams, the Adviser has assigned each investment team to either a U.S. or EMEA/APAC IPO indication group (each an “IPO Indication Group”) and places two separate indications with a broker for any one limited offering. The Adviser’s allocation procedures generally require all securities of an offering allocated to an IPO Indication Group be allocated to all accounts based on portfolio management’s participation in such IPO Indication Group based on their initial indications and on a pro rata basis to all participating eligible accounts based on the total assets of each account. When more than one portfolio management across the firm indicates interest in a primary or secondary limited offering, a limit on the allowable bid will be applied. In addition, with respect to private equity offerings, the Adviser limits the amount that any one fund can own, in the aggregate, of all private companies. Deviations from these procedures are permitted provided such deviations are documented and approved by an Asset Class Head or a delegate. A deviation could occur, for example, in order to allocate additional securities to ensure that accounts receive sufficient securities to satisfy specialized investment objectives or policies, to account for allocation sizes that are deemed by the Adviser to be de minimis for certain eligible accounts, to address market conditions, to address situations specific to individual accounts (e.g., cash limitations, position weightings, liquidity profiles of the investment, redemption history of the account, etc.). Additionally, for primary and secondary offerings of common stock, additional shares may be allocated to the applicable accounts of portfolio management with a preexisting position in that security. Deviations from pro rata allocations may contribute to differences in performance among eligible accounts within the same strategy. The Adviser cannot assure in all instances, participations in IPOs or limited offerings by all eligible accounts. In the event an eligible account does not participate in an offering, the Adviser generally does not reimburse for opportunity costs.

Creation or redemption transactions, to the extent consisting of cash, may require the Fund to contemporaneously transact with broker-dealers for purchases of Deposit Securities (as defined under Fund Deposit) or sales of Fund Securities (as defined under Redemption of Creation Units), including any foreign exchange, as applicable. Such transactions with a particular broker-dealer may be conditioned upon the broker-dealer’s agreement to transact at guaranteed price levels in order to reduce transaction costs the Fund would otherwise incur as a consequence of settling creation or redemption baskets in cash rather than in-kind.

29

The following table summarizes the total amount of brokerage commissions paid by the Fund from the period of commencement of operations on February 4, 2025 through October 31, 2025.

Brokerage commissions paid by the Fund may vary significantly from year to year because of portfolio turnover rates, shareholder, broker-dealer, or other financial intermediary purchase/redemption activity, varying market conditions, changes to investment strategies or processes, and other factors.

As of October 31, 2025, the Fund did not own any securities of its regular broker-dealer (or parents).

30

Shares of the Trust

As stated in the Fund’s Prospectus, the net asset value (“NAV”) of the shares of the Fund is determined once each day the New York Stock Exchange (the “NYSE”) is open, as of the close of its trading session (normally 4:00 p.m., New York time, Monday through Friday). The per share NAV of the Fund is computed by dividing the net assets by the number of the Fund’s shares outstanding.

Securities held by the Fund are valued in accordance with policies and procedures established by the Adviser pursuant to Rule 2a-5 under the 1940 Act and approved by and subject to the oversight of the Trustees (the “Valuation Procedures”). In determining NAV, equity securities traded on a domestic securities exchange are generally valued at the readily available market quotations, which are (i) the official close prices or (ii) last sale prices on the primary market or exchange in which the securities trade. If such price is lacking for the trading period immediately preceding the time of determination, such securities are valued at their current bid price. If applicable, equity securities that are traded on a foreign exchange are generally valued at the closing prices on such markets. In the event that there is no current trading volume on a particular security in such foreign exchange, the bid price from the primary exchange is generally used to value the security. Securities that are traded on the over-the-counter markets are generally valued at their closing or latest bid prices as available. Foreign securities and currencies are converted to U.S. dollars using the applicable exchange rate in effect at the close of the London Stock Exchange. The Adviser will determine the market value of individual securities held by it by using prices provided by one or more Adviser-approved professional pricing services or, as needed, by obtaining market quotations from independent broker-dealers. Most debt securities are valued in accordance with the evaluated bid price supplied by the pricing service that is intended to reflect market value. The evaluated bid price supplied by the pricing service is an evaluation that may consider factors such as security prices, yields, maturities, and ratings. Certain short-term securities maturing within 60 days or less may be valued on an amortized cost basis.

Securities for which market quotations or evaluated prices are not readily available or are deemed unreliable are valued at fair value determined in good faith by the Adviser pursuant to the Valuation Procedures. Circumstances in which fair valuation may be utilized include, but are not limited to: (i) a significant event that may affect the securities of a single issuer, such as a merger, bankruptcy, or significant issuer-specific development; (ii) an event that may affect an entire market, such as a natural disaster or significant governmental action; (iii) a nonsignificant event such as a market closing early or not opening, or a security trading halt; and (iv) pricing of a non-valued security and a restricted or nonpublic security. Special valuation considerations may apply with respect to “odd-lot” fixed-income transactions which, due to their small size, may receive evaluated prices by pricing services which reflect a large block trade and not what actually could be obtained for the odd-lot position.

The Fund calculates its NAV per share, and therefore effects sales, redemptions, and repurchases of its shares, as of the close of the NYSE once each day on which the NYSE is open. Such calculation may not take place contemporaneously with the determination of the prices of the foreign portfolio securities used in such calculation. If an event that is expected to affect the value of a portfolio security occurs after the close of the principal exchange or market on which that security is traded, and before the close of the NYSE, then that security may be valued in good faith under the Valuation Procedures.

Rule 12b-1 under the 1940 Act, as amended, (the “Rule”) provides that an investment company may bear expenses of distributing its shares only pursuant to a plan adopted in accordance with the Rule. The Trustees have adopted a Rule 12b-1 Distribution Plan (“Rule 12b-1 Plan”) pursuant to which the Fund may pay certain expenses incurred in the distribution of its shares and the servicing and maintenance of existing shareholder accounts. ALPS, as the Fund’s principal underwriter, and the Adviser may have a direct or indirect financial interest in the Rule 12b-1 Plan or any related agreement. Pursuant to the Rule 12b-1 Plan, the Fund may pay a fee of up to 0.25% of the Fund’s average daily net assets. No Rule 12b-1 fee is currently being charged to the Fund.

The Rule 12b-1 Plan was approved by the Board, including a majority of the Independent Trustees of the Fund. In approving the Rule 12b-1 Plan, the Trustees determined that there is a reasonable likelihood that the Rule 12b-1 Plan will benefit the Fund and its shareholders.

31

The Rule 12b-1 fee may only be imposed or increased when the Trustees determine that it is in the best interests of shareholders to do so. Because these fees are paid out of the Fund’s assets on an ongoing basis, to the extent that a fee is authorized, over time they will increase the cost of an investment in the Fund. The Rule 12b-1 fee may cost an investor more than other types of sales charges.

The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor, without a sales load, at the NAV next determined after receipt of an order in proper form as described in the Participant Agreement (as defined below), on any Business Day (as defined below). The size of a Creation Unit to purchase shares of the Fund may differ from the size of a Creation Unit required to redeem shares of the Fund. The size of a Creation Unit may be modified by the Adviser with prior notification to the Fund’s Authorized Participants. The Fund’s current Creation Unit size may be found on the ETF portion of the Janus Henderson website.

A “Business Day” with respect to the Fund is each day the Listing Exchange is open, which excludes weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Orders from Authorized Participants to create or redeem Creation Units will only be accepted on a Business Day.

Fund Deposit

The consideration for purchase of Creation Units of the Fund may consist of cash or securities (plus an amount of cash). If creations are not conducted in cash, the consideration for purchase of Creation Units of the Fund generally consists of “Deposit Securities” and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which will be applicable (subject to possible amendment or correction) to creation requests received in proper form. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund.

The “Cash Component” is an amount equal to the difference between the NAV of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the NAV per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit.

The Adviser makes available through the NSCC on each Business Day prior to the opening of business on the Listing Exchange, the list of names and the required number or par value of each Deposit Security, if any, and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day for the Fund). Such Fund Deposit is applicable, subject to any adjustments as described below, to purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

The identity and number or par value of the Deposit Securities change pursuant to changes in the composition of the Fund’s portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by the Adviser with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the Fund’s portfolio.

The Fund reserves the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through Depository Trust Company (“DTC”) or the Clearing Process (as discussed below). The Fund also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which (i) the delivery of the Deposit Security by the Authorized Participant (as described below) would be restricted under applicable securities or other local laws or (ii) the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under applicable securities or other local laws, or in certain other situations. In the case of transactions involving “cash in lieu” amounts, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser. If a purchase or redemption consists solely or partially of cash and the Fund places a brokerage transaction for portfolio securities with a third party

32

broker, an Authorized Participant or its affiliated broker-dealer, the broker or the Authorized Participant (or an affiliated broker-dealer of the Authorized Participant) may be required, in its capacity as broker-dealer with respect to that transaction, to cover certain brokerage, tax, execution, and market impact costs through a brokerage execution guarantee.

Procedures for Creating Creation Units

To be eligible to place orders with the Distributor and to create a Creation Unit of the Fund, an entity must be: (i) a “Participating Party,” i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the “Clearing Process”) or (ii) a DTC Participant, and must have executed an agreement with the Distributor, with respect to creations and redemptions of Creation Units (“Participant Agreement”) (discussed below). A Participating Party or DTC Participant who has executed a Participant Agreement is referred to as an “Authorized Participant.” All shares of the Fund, however created, will be entered on the records of DTC in the name of Cede & Co. for the account of a DTC Participant.

Role of the Authorized Participant

Creation Units may be purchased only by or through a DTC Participant that has entered into a Participant Agreement with the Distributor. Such Authorized Participant will agree, pursuant to the terms of such Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fees described below. An Authorized Participant, acting on behalf of an investor, may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed a Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through a non-Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into a Participant Agreement with more than a small number of DTC Participants. The Distributor and Transfer Agent have adopted guidelines regarding Authorized Participants’ transactions in Creation Units that are made available to all Authorized Participants. These guidelines set forth the processes and standards for Authorized Participants to transact with the Distributor, Transfer Agent, and their agents in connection with creation and redemption transactions, as applicable.

Placement of Creation Orders

Fund Deposits must be delivered through the Federal Reserve System (for cash and U.S. government securities), through DTC (for corporate and municipal securities) or through a central depository account, such as with Euroclear or DTC, maintained by the Custodian or a subcustodian (a “Central Depository Account”). Any portion of a Fund Deposit that may not be delivered through the Federal Reserve System or DTC must be delivered through a Central Depository Account. The Fund Deposit transfers made through DTC must be ordered by the DTC Participant in a timely fashion so as to ensure the delivery of the requisite number of Deposit Securities through DTC to the account of the Fund generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through the Federal Reserve System must be deposited by the participant institution in a timely fashion so as to ensure the delivery of the requisite number or amount of Deposit Securities or cash through the Federal Reserve System to the account of the Fund generally before 3:00 p.m., Eastern time on the Settlement Date. Fund Deposit transfers made through a Central Depository Account must be completed pursuant to the requirements established by the Custodian or subcustodian for such Central Depository Account generally before 2:00 p.m., Eastern time on the Settlement Date. The “Settlement Date” for all funds is generally the first Business Day after the Transmittal Date. All questions as to the number of Deposit Securities to be delivered, and the validity, form and eligibility (including time of receipt) for the deposit of any tendered securities, will be determined by the Trust, whose determination shall be final and binding. The amount of cash equal to the Cash Component must be transferred directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian generally before 3:00 p.m., Eastern time on the Settlement Date. If the Cash Component and the Deposit Securities are not received by 3:00 p.m., Eastern time on the Settlement Date, the creation order may be canceled. Upon written notice to the Distributor, such canceled order may be resubmitted the following Business Day using a Fund Deposit as newly constituted to reflect the then current NAV of the Fund. The delivery of Creation Units so created generally will occur no later than the first Business Day following the day on which the purchase order is deemed received by the Distributor, provided that the relevant Fund Deposit has been received by the Fund prior to such time.

Purchase Orders

To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor or its agent an irrevocable order to purchase shares of the Fund, in proper form, by the Cutoff Time (as defined below). The Distributor or its agent will notify the Adviser and the Custodian of such order. The Custodian will then provide such information to any appropriate subcustodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the Participant Agreement and may change from time to time. Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor or its agent by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Fund, immediately available or same day funds estimated by the Fund to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Any excess funds will be returned following settlement of the issue of the Creation Unit. Those placing orders should ascertain the deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time of the Fund. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Timing of Submission of Purchase Orders

An Authorized Participant must submit an irrevocable order to purchase shares of the Fund generally before 3:00 p.m. (for negotiated custom baskets) or 4:00 p.m. (for standard orders), Eastern time on any Business Day in order to receive that day’s NAV, or until the market closes (in the event the Listing Exchange closes early). On days when the Listing Exchange closes earlier than normal, the Fund may require orders to create or redeem Creation Units to be placed earlier in the day. Creation Orders must be transmitted by an Authorized Participant by telephone or other transmission method acceptable to the Distributor or its agent pursuant to procedures set forth in the Participant Agreement, as described below. Economic or market disruptions or changes, or telephone or other communication failure, may impede the ability to reach the Distributor or its agent or an Authorized Participant. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) when the equity markets in the relevant foreign market are closed may be charged the maximum additional charge for Creation Unit transactions as set forth in this SAI to account for transaction costs incurred by the Fund. The Fund’s deadline specified above for the submission of purchase orders is referred to as the Fund’s “Cutoff Time.” The Distributor or its agent, in their discretion, may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor’s or its Transfer Agent’s proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance. However, to account for transaction costs otherwise incurred by the Fund, an Authorized Participant that submits an order to the Distributor after the Cutoff Time stated above, may be charged the maximum additional charge for Creation Unit transactions as set forth in this SAI.

Acceptance of Orders for Creation Units

Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor’s behalf) and (ii) arrangements satisfactory to the Fund are in place for payment of the Cash Component and any other cash amounts which may be due, the Fund will accept the order, subject to the Fund’s right (and the right of the Distributor and the Adviser) to reject any order until acceptance, as set forth below.

Once the Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor or its agent will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

The Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor or its agent if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the

34

Fund Deposit would, in the discretion of the Fund or the Adviser, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor or its agent and the Adviser make it impracticable to process purchase orders. The Distributor or its agent shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, Transfer Agent, subcustodian, and Distributor or their agents are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit

Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant subcustodian or subcustodians, the Distributor or its agent and the Adviser shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit. Creation Units for the Fund typically are issued on a “T+1 basis” (i.e., one Business Day after trade date). However, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+1, including a shorter settlement period, if necessary or appropriate under the circumstances and compliant with applicable law. For example, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+1, in order to accommodate foreign market holiday schedules, to account for different treatment among foreign and U.S. markets, as applicable, of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security) and in certain other circumstances.

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, the Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Fund Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant’s delivery and maintenance of collateral having a value at least equal to 105%, which percentage the Adviser may change at any time, in its sole discretion, of the value of the missing Deposit Securities in accordance with the Fund’s then-effective procedures. The only collateral that is acceptable to the Fund is cash in U.S. dollars. Such cash collateral must be delivered no later than 2:00 p.m., Eastern time on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Fund’s current procedures for collateralization of missing Deposit Securities is available from the Distributor or its agent. The Participant Agreement will permit the Fund to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such securities and the cash collateral.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Fund reserves the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund’s determination shall be final and binding.

Redemption of Creation Units

Shares of the Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Transfer Agent or its agent and only on a Business Day. The Fund will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market. The Fund redeems Creation Units in-kind plus any Cash Amount due or entirely in cash.

In-Kind Redemption Method

The Adviser will make available through the NSCC, prior to the opening of business on the Listing Exchange (currently 9:30 a.m. Eastern time) on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (the “Cash Amount,” as described below). Such Fund Securities and the corresponding Cash Amount (each subject to possible amendment or correction) are applicable in order to effect redemptions of Creation Units of the Fund until such time as the next announced

35

composition of the Fund Securities and Cash Amount is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units. Procedures and requirements governing redemption transactions are set forth in the handbook for Authorized Participants and may change from time to time.

With an in-kind redemption, the proceeds for a Creation Unit generally consist of Fund Securities, plus the Cash Amount, which is an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a redemption request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below).

The Fund may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security, and reserves the right to redeem entirely in cash. The Fund also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which: (i) the delivery of a Fund Security to the Authorized Participant would be restricted under applicable securities or other local laws; or (ii) the delivery of a Fund Security to the Authorized Participant would result in the disposition of the Fund Security by the Authorized Participant becoming restricted under applicable securities or other local laws, or in certain other situations. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder.

Cash Redemption Method

When partial or full cash redemptions of Creation Units are authorized by the Fund, a custom redemption will be effected in essentially the same manner as in-kind redemptions thereof. In the case of partial or full cash redemption, the Authorized Participant receives the cash equivalent of the Fund Securities it would otherwise receive through an in-kind redemption, plus the same Cash Amount to be paid to an in-kind redeemer.

Costs Associated with Creation and Redemption Transactions

The standard transaction fee (“Standard Fee”) is imposed to offset the transfer and other transaction costs incurred by the Fund associated with the issuance or redemption of Creation Units. The Standard Fee will be charged to the Authorized Participant on the day such Authorized Participant creates or redeems a Creation Unit, and is the same, regardless of the number of Creation Units purchased by the Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction. For creations, Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. The Adviser may adjust the Standard Fee from time to time to account for changes in transaction fees associated with in-kind transactions.

In addition to the Standard Fees discussed above, the Fund charges an additional variable fee (“Variable Fee”) for creations and redemptions in whole or partial cash to offset brokerage and impact expenses associated with the cash portion of the transaction. The amount of the Variable Fee payable to the Fund by the Authorized Participant is determined by the Adviser based on analysis of historical transaction cost data and the Adviser’s view of current market conditions, among other factors. The actual Variable Fee charged for a given transaction may be lower or higher than the trading expenses incurred by the Fund with respect to that transaction. The total transaction fees charged (i.e. the Standard Fee plus the Variable Fee) will not exceed the maximum amounts reflected in the table below. From time to time, the Adviser, in its sole discretion, may adjust the Fund’s transaction fees or reimburse an Authorized Participant for all or a portion of the transaction fees.

The following table shows as of the date of this SAI (i) the Standard Fee, and (ii) the maximum total transaction fee charges for creations and redemptions (as described above):

36

Placement of Redemption Orders

Redemption requests for Creation Units of the Fund must be submitted to the Transfer Agent by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of the Fund generally before 3:00 p.m. (for negotiated custom baskets) or 4:00 p.m. (for standard orders), Eastern time on any Business Day, in order to receive that day’s NAV. On days when the Listing Exchange closes earlier than normal, the Fund may require orders to create or redeem Creation Units to be placed earlier in the day. Investors, other than Authorized Participants, are responsible for making arrangements for a redemption request to be made through an Authorized Participant.

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Transfer Agent or its agent in accordance with procedures set forth in the Participant Agreement. Investors should be aware that their particular broker may not have executed a Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor’s broker through an Authorized Participant who has executed a Participant Agreement. At any time, only a limited number of broker-dealers will have a Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Transfer Agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if (i) an Authorized Participant has transferred or caused to be transferred to the Transfer Agent the Creation Unit redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on the applicable Business Day, (ii) a request in form satisfactory to the Fund is received by the Transfer Agent or its agent from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above and (iii) all other procedures set forth in the Participant Agreement are properly followed. If the Transfer Agent does not receive the investor’s shares through DTC’s facilities by 10:00 a.m., Eastern time on the Business Day next following the day that the redemption request is received, the redemption request may be rejected. Investors should be aware that the deadline for such transfers of shares through the DTC system may be significantly earlier than the close of business on the Listing Exchange. Those making redemption requests should ascertain the deadline applicable to transfers of shares through the DTC system by contacting the operations department of the broker or depositary institution effecting the transfer of the shares.

Upon receiving a redemption request, the Transfer Agent or its agent shall notify the Fund of such redemption request. The tender of an investor’s shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Beneficial Owner or Authorized Participant acting on behalf of such Beneficial Owner must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the portfolio securities are customarily traded, to which account such portfolio securities will be delivered.

Deliveries of redemption proceeds by the Fund generally will be made within one Business Day (i.e., “T+1”). Further, consistent with applicable law, the Fund reserves the right to settle redemption transactions and deliver redemption proceeds on another basis to accommodate foreign market holiday schedules, including to account for different treatment among foreign and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances.

If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable foreign jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, the Fund may in its discretion exercise the option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above, to offset the Fund’s brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be

37

subject to compliance with applicable U.S. federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.

In the event that cash redemptions are utilized by the Fund, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (generally within seven calendar days thereafter, except as described in “Regular Holidays” below).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor or its agent, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Transfer Agent or its agent will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105%, which percentage the Adviser may change at any time, in its sole discretion, of the value of the missing shares. Such cash collateral must be delivered no later than 10:00 a.m., Eastern time on the day after the date of submission of such redemption request and shall be held by the Custodian and marked-to-market daily. The fees of the Custodian and any subcustodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Participant Agreement permits the Fund to acquire shares of the Fund at any time and subjects the Authorized Participant to liability for any shortfall between the aggregate of the cost to the Fund of purchasing such shares, plus the value of the Cash Amount, and the value of the cash collateral.

Because the portfolio securities of the Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for the Fund, shareholders may not be able to redeem their shares of the Fund, or purchase or sell shares of the Fund on the Listing Exchange on days when the NAV of the Fund could be significantly affected by events in the relevant foreign markets.

The right of redemption may be suspended or the date of payment postponed with respect to the Fund: (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings); (ii) for any period during which trading on the Listing Exchange is suspended or restricted; (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Custom Baskets

The securities and other assets that are required for the issuance of a Creation Unit, or are provided upon redemption of a Creation Unit (a “basket”) may differ and the Fund may permit or require the submission of a portfolio of securities or cash that differs from the composition of the published portfolio(s) (a “Custom Basket”). A Custom Basket may include any of the following: (i) a basket that is composed of a nonrepresentative selection of the Fund’s portfolio holdings; or (ii) a representative basket that is different from the initial basket used in transactions on the same business day. The Fund has adopted policies and procedures that govern the construction and acceptance of baskets, including heightened requirements for certain types of custom baskets intended to be protective to the Fund and its shareholders. Such policies and procedures, among other items, establish (i) parameters for the construction and acceptance of custom baskets, and (ii) processes for revisions to or deviations from such parameters. The Adviser has established a governance process to oversee basket compliance for the Fund, as set forth in the Fund’s policies and procedures.

Taxation on Creations and Redemptions of Creation Units

An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased (plus any cash received by the Authorized Participant as part of the issue) over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor (plus any cash paid by the Authorized Participant as part of the issue). An Authorized Participant who exchanges Creation Units for Deposit Securities generally will recognize a gain or loss equal to the difference between the Authorized Participant’s basis in the Creation Units (plus any cash paid by the Authorized Participant as part of the redemption) and the aggregate market value of the Deposit Securities (plus any cash received by the Authorized Participant

38

as part of the redemption). However, the Internal Revenue Service (the “IRS”) may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Regular Holidays

For every occurrence of one or more intervening holidays in the applicable foreign market that are not holidays observed in the U.S. equity market, the redemption settlement cycle will be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a foreign market due to emergencies may also prevent the Trust from delivering securities within the normal settlement period.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with foreign market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. Under normal circumstances, the Fund expects to pay out redemption proceeds within one Business Day after the redemption request is received, in accordance with the process set forth in the Fund’s SAI and in the agreement between the Authorized Participant and the Fund’s Distributor. However, the Fund reserves the right, including under stressed market conditions, to take up to seven days after the receipt of a redemption request to pay the Authorized Participant, all as permitted by the 1940 Act. With respect to the Fund’s foreign investments, in a country where local market holiday(s) prevent the Fund from delivering such foreign investments to an Authorized Participant in response to a redemption request, the Fund may take up to 15 days after the receipt of the redemption request to deliver such investments to the Authorized Participant.

39

Securities Lending

The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions. JPMorgan Chase Bank, N.A. acts as securities lending agent and custodian or subcustodian to receive and disburse cash balances and cash collateral, hold short-term investments, and perform other custodian functions in accordance with the Securities Lending Agreement.

During the Fund’s last fiscal year, the securities lending services provided by JPMorgan Chase Bank, N.A., included negotiating the terms of loans; monitoring approved borrowers; recalling and arranging the return of loaned securities to the Fund upon termination of the loan; marking to market loans; providing recordkeeping services; reporting on the Fund’s securities lending activities; and related services. The following table summarizes the income and fees from securities lending activities for the fiscal year ended October 31, 2025 for the Fund.

Income Dividends, Capital Gains Distributions, and Tax Status

The following is intended to be a general summary of certain U.S. federal income tax consequences of investing in the Fund. It is not intended to be a complete discussion of all such federal income tax consequences, nor does it purport to deal with all categories of investors. This summary assumes that investors hold shares of the Fund as capital assets (within the meaning of the Internal Revenue Code). This summary does not apply to investors that are not “United States persons” (as such term is defined under Section 7701(a)(30) of the Internal Revenue Code) or investors subject to special tax treatment (such as a partnership, financial institution, real estate investment trust, regulated investment company, insurance company, tax-advantaged, tax-qualified and retirement plans (or any other tax-exempt entity), or dealer in securities), except as otherwise specifically indicated below. This discussion reflects applicable tax laws of the United States as of the date of this SAI. However, tax laws may change or be subject to new interpretation by the courts or the IRS, possibly with retroactive effect. Investors are therefore advised to consult with their own tax advisers before making an investment in the Fund.

It is a policy of the Fund to make distributions of substantially all of their respective net investment income and any realized net capital gains at least annually. Any net capital gains realized during each fiscal year, as defined by the Internal Revenue Code, are normally declared and payable to shareholders in December but, if necessary, may be distributed at other times as well.

The Fund intends to qualify as a regulated investment company as such term is defined under Subchapter M of the Internal Revenue Code (a “regulated investment company”). If the Fund failed to qualify as a regulated investment company in any taxable year, the Fund may be subject to federal income tax on its taxable income at the applicable corporate tax rate. In addition, all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, would generally be taxable to shareholders as ordinary income but may, at least in part, qualify for the dividends-received deduction applicable to corporations or the reduced rate of taxation applicable to noncorporate holders for “qualified dividend income.” In addition, the Fund could be required to recognize unrealized gains, pay taxes and interest, and make distributions before requalifying as a regulated investment company that is accorded special federal income tax treatment. Even if the Fund qualifies as a regulated investment company in a taxable year, the Fund will generally be subject to federal income tax on its undistributed investment company taxable income and net tax-exempt income (if any) at the applicable corporate tax rate.

A non-deductible U.S. federal excise tax at the rate of 4% will be imposed on the excess, if any, of the Fund’s “required distribution” over actual distributions in any calendar year. Generally, the “required distribution” is 98% of the Fund’s ordinary income for the calendar year plus 98.2% of its capital gain net income recognized during the one-year period ending on October 31 plus undistributed amounts from prior years. The Fund intends to make distributions sufficient to avoid imposition of the excise tax.

Certain transactions involving short sales, futures, options, swap agreements, hedged investments, and other similar transactions, if any, may be subject to special provisions of the Internal Revenue Code that, among other things, may affect the character, amount, and timing of distributions to shareholders. The Fund will monitor its transactions and may make certain tax elections where applicable in order to mitigate the effect of these provisions, if possible.
