PGIM Rock ETF Trust – PGIM S&P 500 Quarterly Buffer 15 ETF is an actively managed exchange-traded fund launched by PGIM Investments LLC and co-managed by PGIM Quantitative Solutions LLC. The Fund seeks to provide investment results that correspond, before fees and expenses, to the price return of the SPDR S&P 500 ETF Trust, up to a predetermined upside cap, while buffering the first 15% of losses in the underlying SPDR S&P 500 ETF Trust over each approximate three-month target outcome period. The Fund primarily employs FLexible EXchange Options, or FLEX Options, referencing SPDR S&P 500 ETF Trust shares, together with cash and cash-equivalent collateral, to construct its defined-outcome exposure; it offers exposure to U.S. large-capitalization equity markets across diversified industry sectors, subject to a capped return and downside losses beyond the applicable 15% buffer. The Fund is designed for investors seeking defined quarterly equity-market outcomes and is benchmarked to the S&P 500 Price Return Index. PGIM S&P 500 Quarterly Buffer 15 ETF is a series of PGIM Rock ETF Trust, is domiciled in the United States, has an inception date of June 30, 2026, and trades on the Cboe BZX Exchange under the ticker symbol PQXV. PGIM Investments LLC, headquartered in Newark, New Jersey, serves as the Fund’s sponsor and investment manager and is part of PGIM, the global investment-management business of Prudential Financial, Inc. The Fund’s principal recent development is its July 2026 launch as one of four new PGIM S&P 500 Quarterly Buffer ETFs, alongside the 5%, 10%, and 20% buffer variants; the launch expands PGIM’s buffer ETF platform by adding approximate three-month target outcome periods to its pre-existing annual-outcome offerings. The quarterly series resets its options-based portfolio and establishes a new upside cap at the beginning of each target outcome period, and carries a 0.50% net expense ratio.
