### Footnotes:

(1) This transaction represents the vesting on June 13, 2025 of 422,475 Restricted Stock Units ("RSUs") granted on June 13, 2024 under the Company's 2021 Equity Incentive Plan (as amended and restated on April 22, 2024) and reported on the Form 4 filed August 9, 2024. This relates to the vesting of the first of three equal annual installments (further details in Note 7 below). Each RSU represents the right to receive one share of Common Stock. These 422,475 RSUs were settled in shares of Common Stock on March 13, 2026.

(2) This transaction represents the vesting on January 1, 2026 of 500,000 RSUs granted on January 1, 2025 under the Company's 2021 Equity Incentive Plan (as amended and restated on April 22, 2024) and reported on the Form 4 filed January 3, 2025. This relates to the vesting of the second of three equal annual installments (further details in Note 8 below). Each RSU represents the right to receive one share of Common Stock. These 500,000 RSUs were settled in shares of Common Stock on March 13, 2026.

(3) This transaction represents 212,137 shares of Common Stock withheld for tax obligations in connection with the settlement on March 30, 2026 of 500,000 RSUs that vested on January 1, 2025 (the first of three equal annual installments). Those 500,000 RSUs had previously vested as reported on the Form 4 filed on January 3, 2025, however, settlement did not occur until March 30, 2026. Because the vesting of those 500,000 RSUs was previously reported, only the tax withholding is reported on this Form 4.

(4) This transaction represents 195,775 shares of Common Stock withheld for tax obligations in connection with the settlement on March 13, 2026 of 422,475 RSUs that vested on June 13, 2025 (the first of three equal annual installments). The vesting of those 422,475 RSUs is described in Note 1 above.

(5) This transaction represents 210,688 shares of Common Stock withheld for tax obligations in connection with the settlement on March 13, 2026 of 500,000 RSUs that vested on January 1, 2026 (the second of three equal annual installments). The vesting of those 500,000 RSUs is described in Note 2 above.

(6) The 1,484,337 shares of Common Stock beneficially owned following the reported transactions reflects: (i) 1,180,462 shares reported on the Form 4 filed January 3, 2025; plus (ii) 422,475 shares acquired upon vesting of RSUs on June 13, 2025 and subsequently settled on March 13, 2026 (Note 1 above); plus (iii) 500,000 shares acquired upon vesting of RSUs on January 1, 2026 and subsequently settled on March 13, 2026 (Note 2 above); less (iv) 212,137 shares withheld for tax upon settlement of RSUs on March 30, 2026 (Note 3 above); less (v) 195,775 shares withheld for tax upon settlement of RSUs on March 13, 2026 (Note 4 above); less (vi) 210,688 shares withheld for tax upon settlement of RSUs on March 13, 2026 (Note 5 above).

(7) The RSUs reported on the Form 4 filed August 9, 2024 were granted for a total of 1,267,427 RSUs vesting in three equal annual installments: one-third vested on June 13, 2025; one-third will vest on June 13, 2026; and the remaining one-third will vest on June 13, 2027. Following the vesting and settlement of the first installment reported herein, 844,952 RSUs remain outstanding.

(8) The RSUs reported on the Form 4 filed January 3, 2025 were granted for a total of 1,500,000 RSUs vesting in three equal annual installments: one-third vested on January 1, 2025; one-third vested on January 1, 2026; and the remaining one-third will vest on January 1, 2027. That filing reported 500,000 shares acquired in Table I and 1,000,000 RSUs in Table II, representing the unvested second and third installments. Following the vesting and settlement of the second installment reported herein, 500,000 RSUs remain outstanding and are reported in Table II, representing the third and final installment of the grant dated January 1, 2025. No Table II disposition was reported for the first installment because those RSUs were converted to shares upon vesting on January 1, 2025 and reported in Table I on the prior filing, not in Table II.
