On December 4, 2025, the Issuer's board of directors declared a quarterly cash dividend in the amount of $0.15 per share of its common stock, payable on December 31, 2025 to stockholders of record of the common stock at the close of business on December 15, 2025 (the "Dividend"). The amount acquired in column 4 represents equivalent rights accrued as a result of the Dividend on restricted stock units with respect to the Issuer's common stock ("Original RSUs") held by the reporting person. Each dividend equivalent right entitles the reporting person to receive one share of the Issuer's common stock upon the settlement of the Original RSUs and is subject to the same terms and conditions, including vesting and settlement, as the Original RSUs to which it relates. The grant of dividend equivalent rights was approved by the Issuer's board of directors pursuant to Rule 16b-3 of the Securities Exchange Act of 1934, as amended.

2. This security represents restricted stock units. Each restricted stock unit represents a contingent right to receive one share of common stock of the issuer.

3. The shares underlying these restricted stock units vest on January 6, 2027, subject to the reporting person's continued service with the issuer.
