### Footnotes:

(1) West-Karam Family Trust is the record holder of such securities. The reporting person is trustee of the West-Karam Family Trust, of which the reporting person and members of the reporting person's immediate family are the sole beneficiaries. The reporting person remains the beneficial owner of the securities held by the trust.

(2) The sales price reported is the weighted average sale price for the number of shares sold. These shares were sold in multiple transactions at prices ranging from $18.17 to $18.19, inclusive. Full information regarding the number of shares sold at each separate price will be supplied upon request by Securities and Exchange Commission Staff, the Issuer or a security holder of the Issuer.

(3) Consists of 19,837 unvested restricted stock units.

**Remarks:**
This Form 4/A amends the Form 4 filed by the reporting person on August 15, 2025 (the "Initial Form 4"). As previously reported in the Form 4 filed by the reporting person on August 20, 2025, commencing on July 12, 2024, a portion of the reporting person's beneficial ownership of shares of Common Stock has consisted of indirect beneficial ownership  of shares through the West-Karam Family Trust, and commencing on August 22, 2024, the reporting person ceased to indirectly beneficially own shares of Common Stock through Emerging Company Partners LLC. Accordingly, this Form 4/A corrects the Initial Form 4 in the following respects: (1) line 1 of Table I has been amended to reflect that 119,000 shares of Common Stock were sold by the West-Karam Family Trust rather than the reporting person in his direct capacity, and that following such reported transaction, the reporting person indirectly beneficially owns 118,840 shares of Common Stock through the West-Karam Family Trust; (2)  line 2 of Table I continues to reflect the sale of 25,000 shares by the reporting person in his direct capacity, and has been amended to reflect that following such reported transaction, the reporting person directly beneficially owns 19,837 shares of Common Stock, consisting of unvested restricted stock units; and (3)  line 3 of Table I has been deleted, because the reporting person ceased to indirectly beneficially own shares of Common Stock through Emerging Company Partners LLC on August 22, 2024.
