Form 4 Filing by Robert Keith Warner

This filing details transactions made by Robert Keith Warner, a director at Rx Sight, Inc. On June 17, 2026, Mr. Warner acquired 37,037 shares of Common Stock through a restricted stock unit (RSU) award. These RSUs vest fully on the earlier of the one-year anniversary of the grant date or the next annual stockholder meeting, provided Mr. Warner remains an Outside Director. The filing also includes a Power of Attorney document, appointing several individuals to act on Mr. Warner's behalf in executing and submitting required SEC filings, including Forms 3, 4, and 5, and Schedules 13D and 13G. This Power of Attorney authorizes the appointed attorneys-in-fact to gather information on the company's securities and grants them broad powers to act in Mr. Warner's stead, though it does not relieve him of his personal responsibility for compliance with securities regulations.
