The bar chart and table below illustrate the annual calendar year returns of the Fund based on NAV as well as the average annual Fund returns. The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year-to-year and by showing how the Fund’s average annual total returns based on NAV compare to those of two broad-based market indices: the MSCI Emerging Markets Total Return Index and the MSCI Emerging Markets Price Index. Both indices have the same constituents in the same weights. However, the MSCI Emerging Markets Total Return Index assumes that any dividends paid out by index constituents have been reinvested in the index and the MSCI Emerging Markets Price Return Index, which measures only the price movements of index constituents, does not. The Fund’s performance information is accessible on the Fund’s website at www.innovatoretfs.com.

The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Returns before taxes do not reflect the effects of any income or capital gains taxes. All after-tax returns are calculated using the historical highest individual federal marginal income taxes and do not reflect the impact of any state or local tax. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains.

The bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund’s performance from year-to-year and by showing how the Fund’s average annual total returns based on NAV compare to those of two broad-based market indices: the MSCI EAFE Total Return Index and the MSCI EAFE Price Index. Both indices have the same constituents in the same weights. However, the MSCI EAFE Total Return Index assumes that any dividends paid out by index constituents have been reinvested in the index and the MSCI EAFE Price Return Index, which measures only the price movements of index constituents, does not.
