2025 Annual Meeting. The AJP / Orbic Parties recommend that I vote “FOR” the election of five AJP / Orbic Nominees. How should I vote with respect to the Company nominees? You will have the ability to vote for any combination (up to five total) of our AJP/Orbic Nominees and the Company’s nominees. We recommend that you vote “WITHHOLD”on the election of the Opposed Company Nominees. However, we believe the best opportunity to elect the AJP/Orbic Nominees is to vote “FOR”all of the AJP/Orbic Nominees, and “WITHHOLD”on, or not vote “FOR”, any Company nominee — on the BLUEuniversal proxy card or BLUEvoting instruction form. How do I revoke a proxy? Any stockholder has the power to revoke a previously submitted proxy at any time before it is exercised even if you submitted a proxy card or form sent to you by the Company.

Please note, however, that only your last -datedproxy will count. Any proxy may be revoked at any time prior to its exercise at the 2025 Annual Meeting as described in this Proxy Statement. Attending the 2025 Annual Meeting alone without taking one of the actions set forth above will not revoke your proxy. Stockholders who hold their shares of Common Stock in “street name” with a bank, brokerage firm, dealer, trust company or other institution or nominee will need to notify the person responsible for their account to revoke or withdraw previously given instructions. You may also provide your bank, brokerage firm, dealer, trust company or other nominee with new voting instructions. Only your latest dated instructions will count. Unless revoked in the manner set forth above and subject to the foregoing, duly authorized proxies in the form enclosed will be voted at the
