Innovator U.S. Small Cap Power Buffer ETF - September (KSEP) is an actively managed exchange-traded fund of Innovator ETFs Trust that seeks to provide investors with returns linked to the price return of the iShares Russell 2000 ETF, subject to a predetermined upside cap and a buffer against the first 15% of losses, before fees and expenses. The fund is a September series defined-outcome ETF listed on Cboe BZX, was launched on September 1, 2024, has a 0.79% expense ratio, and is based in Wheaton, Illinois.
The fund’s primary offering is a buffered small-cap equity strategy implemented through an annual outcome period structure, with the current period running from September 1, 2026 through August 31, 2027; the strategy is designed to be held through the outcome period and then reset on a recurring annual basis. The fund’s core product features include participation in upside up to the stated cap, downside buffering to the specified threshold, and exposure tied to the iShares Russell 2000 ETF benchmark rather than direct ownership of operating businesses.
Recent company developments include a September 2025 net asset value restatement affecting KSEP and other Innovator September buffer ETFs, which Innovator described as a one-time correction with no expected further changes. The latest fund materials also confirm the new 2026–2027 outcome period, reflecting the continuing annual reset of the strategy and ongoing management of the product series.
Innovator Capital Management, LLC manages the fund and operates a broader lineup of defined outcome ETFs across equity and small-cap segments, targeting investors seeking risk-managed market exposure through exchange-traded fund structures. The ETF is distributed in the United States and trades under the ticker KSEP on Cboe BZX.
