Includes 25,752 shares previously reported as indirectly owned by the reporting person's spouse and daughter.

On May 29, 2026, the reporting person contributed 6,204 shares of the issuer's common stock to a limited liability company, of which the reporting person's spouse is manager and a family trust is the sole member. The reporting person is the grantor of such trust and the reporting person's spouse and children are beneficiaries of the trust.

On May 28, 2026, the reporting person and his spouse withdrew 37,856 shares of common stock of the Issuer from a grantor retained annuity trust established for the benefit of himself and his two adult children. 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.
