At a meeting held on July 17, 2026, the Board of Trustees of the Fund approved an Agreement and Plan of Reorganization providing for the reorganization of the Fund into the Alpha Architect U.S. Equity ETF, a fund with the same investment objective and investment adviser but a different sub-adviser, different principal investment strategies, and lower total annual operating expenses (0.0945% versus 0.66% for the Fund).

A combined Information Statement/Prospectus describing the reorganization is expected to be mailed to shareholders on or about September 5, 2026.
