The
Capitol Series Trust (the “Trust”) has adopted an Administrative Services Plan (the “Services Plan”) for
A Shares, Investor Shares, and Institutional Shares of the Funds. The Services Plan allows the A Shares, Investor Shares
and Institutional Shares of the Fund to pay service organizations for the provision of certain administrative, recordkeeping and
other non-distribution related shareholder services to A Share, Investor Share and Institutional Share shareholders. The
Services Plan permits the Fund to make service fee payments at an annual rate of up to 0.25% of the Fund’s average daily net
assets attributable to its A Shares and up to 0.20% of the Fund’s average daily net assets attributable to its Investor Shares
or Institutional Shares. “Other Expenses” reported in the table above for A Shares, Investor Shares and Institutional
Shares include an allocation of up to 0.03% of this services fee payable to the Fund’s investment adviser, Fuller & Thaler
Asset Management, Inc. (“FullerThaler” or the “Adviser”) for certain non-distribution related shareholder
services that it provides pursuant to a Shareholder Services Agreement between the Trust and FullerThaler adopted pursuant to the
Services Plan. This Shareholder Services Agreement and fee allocation to FullerThaler were authorized by the Board of
Trustees (the “Board”) of the Trust pursuant to the Services Plan in March 2023, and is in effect for the Fund. For
additional information regarding the Services Plan, refer to “Service Fees - A Shares, Investor Shares and Institutional Shares”
in the Fund’s prospectus. |

Effective
January 28, 2026, FullerThaler has contractually agreed to waive its management fee and/or reimburse Fund expenses so that total
annual operating expenses do not exceed 1.36%, 1.88% 1.31%, 0.99%, and 0.87% for A Shares, C Shares, Investor Shares, Institutional
Shares and R6 Shares, respectively, of the Fund’s average daily net assets through January 31, 2027. The expense
limitation does not apply to (i) interest (other than custodial overdraft fees), (ii) taxes, (iii) brokerage fees and commissions,
(iv) fees associated with a Fund’s participation in an alternative liquidity program, (v) other extraordinary expenses not
incurred in the ordinary course of the Fund’s business, (vi) dividend expense on short sales and (vii) indirect expenses such
as acquired fund fees and expenses incurred by the Fund in any fiscal year. During any fiscal year that the Investment
Advisory Agreement between the Adviser and the Trust is in effect, the Adviser may recoup the sum of all fees previously waived or
expenses reimbursed, less any reimbursement previously paid, provided that the Adviser is only permitted to recoup fees or expenses
within 36 months from the date the fee waiver or expense reimbursement occurred and provided further that such recoupment can be
achieved within the Expense Limitation Agreement currently in effect and the Expense Limitation Agreement in place when the waiver/reimbursement
occurred. The Expense Limitation Agreement may not be terminated by the Adviser prior to its expiration date, but the
Board may terminate such agreement at any time. The Expense Limitation Agreement shall terminate automatically upon the
termination of the Advisory Agreement. |

payments at an annual rate of up to 0.25% of the Fund’s average daily net assets attributable to its A Shares and up to 0.20%
of the Fund’s average daily net assets attributable to its Investor Shares or Institutional Shares. “Other

0.03% of this services fee payable to the Fund’s investment adviser, Fuller & Thaler Asset Management, Inc. (“FullerThaler”
or the “Adviser”) for certain non-distribution related shareholder services that it provides pursuant to a Shareholder
Services Agreement between the Trust and FullerThaler adopted pursuant to the Services Plan. This Shareholder Services
Agreement and fee allocation to FullerThaler were authorized by the Board of Trustees (the “Board”) of the Trust pursuant
to the Services Plan in March 2023, and is in effect for the Fund. For additional information regarding the Services Plan,

Effective
January 28, 2026, FullerThaler has contractually agreed to waive its management fee and/or reimburse Fund expenses so that total
annual operating expenses do not exceed 1.30%, 1.80%, 1.25%, 0.94% and 0.84% for A Shares, C Shares, Investor Shares, Institutional
Shares and R6 Shares, respectively, of the Fund’s average daily net assets through January 31, 2027. The expense
limitation does not apply to (i) interest (other than custodial overdraft fees), (ii) taxes, (iii) brokerage fees and commissions,
(iv) fees associated with a Fund’s participation in an alternative liquidity program, (v) other extraordinary expenses not
incurred in the ordinary course of the Fund’s business, (vi) dividend expense on short sales and (vii) indirect expenses such
as acquired fund fees and expenses incurred by the Fund in any fiscal year. During any fiscal year that the Investment Advisory Agreement
between the Adviser and the Trust is in effect, the Adviser may recoup the sum of all fees previously waived or expenses reimbursed,
less any reimbursement previously paid, provided that the Adviser is only permitted to recoup fees or expenses within 36 months from
the date the fee waiver or expense reimbursement occurred and provided further that such recoupment can be achieved within the Expense
Limitation Agreement currently in effect and the Expense Limitation Agreement in place when the waiver/reimbursement occurred. This
Expense Limitation Agreement may not be terminated by the Adviser prior to its expiration date, but the Board may terminate such
agreement at any time. The Expense Limitation Agreement shall terminate automatically upon the termination of the Advisory
Agreement. |

The Example assumes that you invest $10,000 in the noted class of shares for the time periods indicated and then redeem all of your shares
at the end of these periods. The Example also assumes that your investment has a 5% return each year, the Fund’s operating expenses
remain the same and the expense waiver/reimbursement remains in place for the contractual period only. Although your actual costs may
be higher or lower, the Example shows what your costs would be based on these assumptions. The Example is based, for the first year,
on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

occurred and provided further that such recoupment can be achieved within the Expense Limitation Agreement currently in effect and
the Expense Limitation Agreement in place when the waiver/reimbursement occurred. This Expense Limitation Agreement may
not be terminated by the Adviser prior to its expiration date, but the Board may terminate such agreement at any time. The
Expense Limitation Agreement shall terminate automatically upon the termination of the Advisory Agreement. |

| Expense Example by, Year, Caption [Text] |
The Example assumes that you invest $10,000 in the noted class of shares for the time periods indicated and then redeem all of your shares
at the end of these periods. The Example also assumes that your investment has a 5% return each year, the Fund’s operating expenses
remain the same and the expense waiver/reimbursement remains in place for the contractual period only. Although your actual costs may
be higher or lower, the Example shows what your costs would be based on these assumptions. The Example is based, for the first year,
on Total Annual Fund Operating Expenses After Expense Reductions and, for all other periods, on Total Annual Fund Operating Expenses.

| Portfolio Turnover [Text Block] |
The
Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). The
Fund’s portfolio turnover rate for the fiscal year ended September 30, 2025 was 111% of the average value of its portfolio.
High levels of portfolio turnover may indicate higher transaction costs and may result in higher taxes for you if your Fund shares are
held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example above, can
adversely affect the Fund’s investment performance.

The
Fund’s A Shares, C Shares, and R6 Shares have been approved by the Capitol Series Trust’s (the “Trust”) Board
of Trustees but are not yet available for purchase and are not being offered at this time. The Fund’s A Shares,
C Shares, and R6 Shares will be offered for sale at a later date. Because the Fund’s A Shares, C Shares, and R6
Shares have no operating history, “Other Expenses” for the share classes are based on estimated expenses for the current
fiscal year. |

The
Trust has adopted an Administrative Services Plan (the “Services Plan”) for A Shares and Institutional Shares of the
Fund. The Services Plan allows the A Shares and Institutional Shares of the Fund to pay service organizations for the
provision of certain administrative, recordkeeping and other non-distribution related shareholder services to A Share and Institutional
Share shareholders. The Services Plan permits the Fund to make service fee payments at an annual rate of up to 0.25% of
the Fund’s average daily net assets attributable to its A Shares and up to 0.20% of the Fund’s average daily net assets
attributable to its Institutional Shares. “Other Expenses” reported in the table above for A Shares and Institutional
Shares include an allocation of up to 0.03% of this services fee payable to the Fund’s investment adviser, Fuller & Thaler
Asset Management, Inc. (“FullerThaler” or the “Adviser”) for certain non-distribution related shareholder
services that it provides pursuant to a Shareholder Services Agreement between the Trust and FullerThaler adopted pursuant to the
Services Plan. This Shareholder Services Agreement and fee allocation to FullerThaler were authorized by the Board of
Trustees (the “Board”) of the Trust pursuant to the Services Plan in March 2023, and is in effect for the Fund. For
additional information regarding the Services Plan, refer to “Service Fees – A Shares, Investor Shares and Institutional
Shares” in the Fund’s prospectus. |

FullerThaler
has contractually agreed to waive its management fee and/or reimburse Fund expenses so that total annual operating expenses do not
exceed 1.23%, 1.78%, 0.79%, and 0.69% for A Shares, C Shares, Institutional Shares and R6 Shares, respectively, of the Fund’s
average daily net assets through January 31, 2027. The expense limitation does not apply to (i) interest (other than custodial
overdraft fees), (ii) taxes, (iii) brokerage fees and commissions, (iv) fees associated with a Fund’s participation in an alternative
liquidity program, (v) other extraordinary expenses not incurred in the ordinary course of the Fund’s business, (vi) dividend
expense on short sales and (vii) indirect expenses such as acquired fund fees and expenses incurred by the Fund in any fiscal year.
During any fiscal year that the Investment Advisory Agreement between the Adviser and the Trust is in effect, the Adviser may recoup
the sum of all fees previously waived or expenses reimbursed, less any reimbursement previously paid, provided that the Adviser is
only permitted to recoup fees or expenses within 36 months from the date the fee waiver or expense reimbursement occurred and provided
further that such recoupment can be achieved within the Expense Limitation Agreement currently in effect and the Expense Limitation
Agreement in place when the waiver/reimbursement occurred. This Expense Limitation Agreement may not be terminated by
the Adviser prior to its expiration date, but the Board may terminate such agreement at any time. The Expense Limitation
Agreement shall terminate automatically upon the termination of the Advisory Agreement. |
