Innovator ETFs Trust - Innovator Equity Defined Protection ETF - 1 Yr December is a U.S.-listed defined-outcome exchange-traded fund that seeks to provide exposure to the return of the SPDR S&P 500 ETF Trust, up to a predetermined cap, while seeking to buffer investors against the first 100% of SPY losses over each approximately one-year outcome period, before fees and expenses. The fund, which trades under the ticker ZDEK on Cboe BZX, uses a portfolio of SPY-linked FLEX Options, including purchased call options, purchased put options and written call options, to establish its capped-upside and downside-protection profile. It targets investors seeking U.S. large-cap equity participation with defined annual outcome parameters and is designed to be held through the entire outcome period; shares purchased after the period begins can have materially different potential returns and protection levels. Innovator ETFs Trust launched the fund on November 29, 2024, with the current December outcome series running from November 30, 2025 through November 30, 2026; the fund resets annually by rolling into a new FLEX Options portfolio and establishing a new cap. ZDEK’s initial cap for the current outcome period is 6.85%, its stated annual expense ratio is 0.79%, and it had approximately $114.2 million in net assets as of June 30, 2026. The fund is sub-advised by Goldman Sachs Asset Management and distributed by Foreside Fund Services LLC. Its most recent material operational development is the commencement of the current annual December outcome period and associated option repositioning, which maintains 100% downside-buffer exposure to SPY, subject to fund fees, expenses, market conditions and the risks of FLEX Options, liquidity, trading and capped returns.
