Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 5 footnotes

Footnote F1

This transaction represents the vesting on January 1, 2026 of 333,333 Restricted Stock Units ("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 5 below). Each RSU represents the right to receive one share of Common Stock. These 333,333 RSUs were settled in shares of Common Stock on March 13, 2026.

Footnote F2

This transaction represents 110,155 shares of Common Stock withheld for tax obligations in connection with the settlement on March 13, 2026 of 333,333 RSUs that vested on January 1, 2026 (the second of three equal annual installments). The vesting of those 333,333 RSUs is described in Note 1 above.

Footnote F3

This transaction represents 134,903 shares of Common Stock withheld for tax obligations in connection with the settlement on March 30, 2026 of 333,333 RSUs that vested on January 1, 2025 (the first of three equal annual installments). Those 333,333 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 333,333 RSUs was previously reported, only the tax withholding is reported on this Form 4.

Footnote F4

The 1,096,608 shares of Common Stock beneficially owned following the reported transactions reflects: (i) 1,008,333 shares reported on the Form 4 filed December 3, 2025; plus (ii) 333,333 shares acquired upon vesting of RSUs on January 1, 2026 and subsequently settled on March 13, 2026 (Note 1 above); less (iii) 110,155 shares withheld for tax upon settlement of RSUs on March 13, 2026 (Note 2 above); less (iv) 134,903 shares withheld for tax upon settlement of RSUs on March 30, 2026 (Note 3 above).

Footnote F5

The RSUs reported on the Form 4 filed January 3, 2025 were granted for a total of 1,000,000 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 333,333 shares acquired in Table I and 666,667 RSUs in Table II, representing the unvested second and third installments. Following the vesting and settlement of the second installment reported herein, 333,334 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.
