Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 4 footnotes

Footnote F1

Includes 184 vested but deferred restricted stock units.

Footnote F2

This Amendment on Form 4/A (this 'Amendment') amends the Form 4 filed on February 17, 2026 (the 'Original Form 4') solely to correct an administrative error, which resulted in the inadvertent erroneous reporting of the equity awards granted to the reporting person on February 12, 2026. Specifically, Table II of the Original Form 4 incorrectly reported that 6,319 restricted stock units (of which 1,580 restricted stock units were deferred) were granted to the reporting person on February 12, 2026, which did not occur. Instead, as reported in this Amendment, a non-qualified stock option to purchase 13,667 shares of Issuer common stock and an incentive stock option to purchase 162 shares of Issuer common stock were granted to the reporting person on February 12, 2026, with an exercise price equal to the closing price of the Issuer's common stock on that day. This Amendment does make any other changes to the Original Form 4.

Footnote F3

Grant of option to buy shares of Issuer common stock that becomes exercisable in four annual installments beginning February 14, 2027.

Footnote F4

Grant of option to buy shares of Issuer common stock that becomes exercisable in one installment on February 14, 2030.
