Innovator ETFs Trust – Innovator Equity Dual Directional 10 Buffer ETF – October is an actively managed, non-diversified U.S. exchange-traded fund that seeks capital appreciation through a defined-outcome strategy linked to the price performance of the State Street SPDR S&P 500 ETF Trust. The Fund employs FLEX Options, and may invest directly in SPDR S&P 500 ETF Trust shares or their underlying components, to provide U.S. large-cap equity exposure with a predetermined annual upside cap, inverse-performance feature and downside buffer. It is designed to participate in gains of the reference asset up to an upside cap; generate positive returns equal to the absolute value of reference-asset losses when such losses are no greater than the inverse-performance threshold; and, if reference-asset losses exceed that threshold, reduce losses by a specified buffer before shareholders participate in further losses on a one-for-one basis. The Fund’s October Series outcome period runs annually from October 1 through September 30, and its portfolio is reset into a new options structure at the close of each outcome period. For the October 1, 2025 through September 30, 2026 outcome period, the Fund established a 12.53% gross upside cap, a 10.00% gross inverse-performance cap and threshold, and a 10.00% gross buffer; its annual expense ratio is 0.79%. The Fund is structured as a series of Innovator ETFs Trust, is advised by Innovator Capital Management LLC and sub-advised by Milliman Financial Risk Management LLC, and its shares trade on Cboe BZX under the ticker DDTO. DDTO was formed on September 30, 2025 and listed on October 1, 2025. Its principal customers are retail and institutional investors, financial advisers and wealth-management platforms seeking exchange-traded, defined-outcome exposure to U.S. equities. Recent major developments include the Fund’s launch and Cboe BZX listing in October 2025, the commencement of its initial October 2025–September 2026 outcome period, and its ongoing annual rebalancing framework, under which the adviser and sub-adviser replace expiring FLEX Options and establish a new upside cap for each succeeding outcome period.
