### Footnotes:

(1) Each restricted stock unit ("RSU") and performance stock unit ("PSU") represents a contingent right to receive one share of the Issuer's common stock.

(2) On July 17, 2025, the Reporting Person was granted 2,500 RSUs vesting 100% on August 7, 2027, subject to the Reporting Person's continued service to the Issuer through the vesting date.

(3) 3. This grant was inadvertently omitted from the original Form 4.

(4) On July 17, 2025, the Reporting Person was granted 6,750 PSUs, a portion of which vests, if the volume-weighted average price of the Issuer's common stock for any consecutive sixty (60) trading-day period equals or exceeds a stock price target.

(5) This amendment corrects an error in the original Form 4, which reported a grant of 5,500 PSUs instead of 6,750 PSUs.

(6) On July 17, 2025, the Reporting Person was granted 1,250 stock options vesting 100% on August 7, 2027, subject to the Reporting Person's continued service to the Issuer through the vesting date.

**Remarks:**
The original Form 4, filed on August 19, 2025, is being amended by this Form 4 amendment to (i) report grants of RSUs and stock options that were inadvertently omitted in the original Form 4 and (ii) correct the number of PSUs granted.
