In exchange for the shares, the reporting person contributed to the trust an amount of cash equal to the value of the shares as determined based on the average of the high and low trading prices of the Issuer's common stock as reported on May 28, 2026. The withdrawal of shares from the trust resulted in a decrease in the number of shares the reporting person beneficially owns indirectly through the trust and a corresponding increase in the number of shares the reporting person beneficially owns directly. The reporting person believes that this withdrawal of shares from the trust constitutes a change in form of beneficial ownership of the shares, exempted by Rule 16a-13 under the Securities Exchange Act of 1934. /s/ Whitney Elliott, Attorney-in-Fact 2026-06-01
