ETF Series Solutions – Aptus April Deep Buffer ETF is an actively managed exchange-traded fund designed to provide defined-outcome exposure to the share-price performance of the SPDR S&P 500 ETF Trust, up to a predetermined upside cap, while seeking to buffer the first 30% of underlying ETF losses, before fees and expenses, over a 12-month investment period. The Fund employs options-based investment strategies, including FLEX Options linked to the SPDR S&P 500 ETF Trust, to establish its capped upside participation and downside buffer; it targets investors seeking S&P 500 equity-market exposure combined with limited downside protection and tax-efficient ETF implementation. The Fund resets its outcome parameters annually in April and trades on Cboe under the ticker APDB. It is a series of ETF Series Solutions, a U.S.-domiciled investment company, and is advised by Aptus Capital Advisors, LLC, which is headquartered in Fairhope, Alabama. The Fund was launched on May 5, 2026, carries a 0.25% expense ratio, and is distributed by Quasar Distributors, LLC. In May 2026, Aptus Capital Advisors expanded its options-based ETF platform by launching APDB alongside the Aptus January Deep Buffer ETF, Aptus July Deep Buffer ETF and Aptus October Deep Buffer ETF, creating a quarterly deep-buffer series intended to offer 30% downside buffers at a lower-cost structure. In 2026, APDB also became a constituent holding of the Aptus Laddered Deep Buffer ETF, extending the Fund’s use within Aptus’s laddered defined-outcome ETF offerings.
