**Annual Meeting of Shareholders

NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

Your vote is extremely important. It is important that your shares be represented at the Annual Meeting whether or not you are personally able to attend. Most stockholders are unable to attend the Annual Meeting. Even if you do plan to attend the Annual Meeting, we urge you to promptly vote by using the enclosed proxy card to vote by telephone or the Internet. You may also sign, date and return the proxy card in the postage-paid envelope provided. Proxy cards that are signed and returned but do not include voting instructions will be voted by the proxies as recommended by the Board of Directors. If your shares are held by a broker, bank or other nominee, you must follow the instructions provided by your broker, bank or other nominee to vote your shares and you may not vote your shares in person at the meeting unless you obtain a “legal proxy” from the broker, bank or other nominee that holds your shares giving you the right to vote the shares at the Annual Meeting. You can change your voting instructions or revoke your proxy at any time prior to the Annual Meeting by following the instructions included in this Proxy Statement and on the proxy card.

If you have any questions or need help voting your shares, please call the firm assisting us with the proxy solicitation:

INTERNET AVAILABILITY OF PROXY MATERIALS

In accordance with rules of the Securities and Exchange Commission, we are using the Internet as our primary means of furnishing proxy materials to stockholders. Because we are using the Internet, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials, including our Proxy Statement and Annual Report, and voting via the Internet. The Notice of Internet Availability of Proxy Materials also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose.

Important Notice Regarding the Availability of Proxy Materials for the Stockholder Meeting to be held on February 18, 2026 at 10:00 a.m. at 1095 Avenue of the Americas, New York, NY 10036. The Company’s Proxy Statement, 2025 Annual Report on Form 10-K and Annual Report to Stockholders will be available online athttp://www.astproxyportal.com/ast/03170.
