As described in Item (2) and Item 5(a) and 5(b) above, effective from May 11, 2026. Mr. Gerald W. Schwartz no longer may be deemed to share beneficial ownership of the shares of Common Stock beneficially owned by Onex Corporation. Mr. Schwartz beneficially owns approximately 0.2% of the Common Stock as a result of his indirect ownership of the equity of Onex Advisor Subco III LLC. Based on certain arrangements regarding the shares of Common Stock held by Onex Advisor Subco III LLC and beneficially owned by Mr. Schwartz, the shares of Common Stock beneficially owned by Mr. Schwartz will be voted in the same manner as shares of Common Stock that may be deemed to be beneficially owned by Onex Corporation. Mr. Schwartz and Onex Corporation may therefore be deemed to be a member of a "group" for purposes of Section 13(d)(3) of the Exchange Act. Mr. Schwartz disclaims beneficial ownership of the shares of Common Stock that may be deemed to be beneficially owned by Onex Corporation, and Onex Corporation disclaims beneficial ownership of the shares of Common Stock beneficially owned by Mr. Schwartz.
