On May 26, 2026, the Board of Directors of Rapid7, Inc. appointed Corey Thomas as Executive Chairman, effective as of June 1, 2026. Mr. Thomas previously served as the Company?s Chief Executive Officer from October 2012 to May 2026 and as Chairman of the Board from February 2019 to June 2025. As Executive Chairman, Mr. Thomas will continue to preside at meetings of the Board and stockholders and will support the Company?s leadership transition and long-term strategic initiatives.

Because Mr. Thomas is not an independent director, the Board appointed Marc Brown, who previously served as Chairman of the Board, as Lead Independent Director, effective June 1, 2026. As part of this effort, Rapid7 has refreshed its senior leadership team, bringing Allan Peters as Chief Commercial Officer, and most recently, Dan Deklich as Chief Product & Technology Officer. This team was constructed to lead Rapid7 through the operational shifts necessary to bring the company from a platform player to the AI-SOC leader.
