NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD VIRTUALLY VIA THE INTERNET ON JUNE 11, 2026

To the Stockholders of Sonida Senior Living, Inc.:

NOTICE IS HEREBY GIVEN that the Annual Meeting of Stockholders (the “Annual Meeting”) of Sonida Senior Living, Inc., a Delaware corporation (the “Company”), will be held live via the Internet in a virtual meeting format at meetnow.global/MVGNUMZ (the “Annual Meeting Website”) on the 11th day of June, 2026 at 9:00 a.m. Central Time, for the following purposes:

1. To elect three directors of the Company to hold office until the Annual Meeting to be held in 2029 or until their respective successors are duly qualified and elected;

2. To ratify the Audit Committee’s appointment of BDO USA, P.C., independent accountants, as the Company’s independent auditors for the fiscal year ending December 31, 2026;

3. To cast an advisory vote on executive compensation;

4. To approve an amendment to the Company’s 2019 Omnibus Stock and Incentive Plan, as amended (the “2019 Plan”), to increase the number of shares of common stock that the Company may issue under the 2019 Plan from 1,797,600 shares to 3,197,600 shares; and

5. To transact any and all other business that may properly come before the Annual Meeting or any adjournment(s) or postponement(s) thereof.

These proposals are described in more detail in the Company’s Proxy Statement. The Board of Directors has fixed the close of business on April 17, 2026 as the record date (the “Record Date”) for the determination of stockholders entitled to notice of and to vote at the Annual Meeting or any adjournment(s) or postponement(s) thereof. Only holders of record at the close of business on the Record Date of shares of the Company’s common stock are entitled to notice of and to vote at the Annual Meeting. The stock transfer books will not be closed. A list of stockholders entitled to vote at the Annual Meeting will be available for examination at the Company’s principal executive offices for ten days prior to the Annual Meeting.

You will be able to attend the Annual Meeting by visiting the Annual Meeting Website and entering a control number. If you hold your shares of the Company’s common stock as a holder of record, your 15-digit control number will be printed on your proxy card. If instead you hold your shares of the Company’s common stock through an account with a bank, broker or other nominee (that is, if you are the beneficial owner of shares held in “street name”), your bank, broker or other nominee may provide you with your 16-digit control number on the voting instruction form it furnishes to you; otherwise, you should contact your bank, broker or other nominee (preferably at least five business days before the date of the Annual Meeting) to obtain a legal proxy that will permit you to attend, and vote at, the Annual Meeting. If you join the Annual Meeting by using your control number or obtaining a legal proxy and logging in to the Annual Meeting Website, you will be able to attend the Annual Meeting and vote your shares online during the Annual Meeting.

Pursuant to rules adopted by the U.S. Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy solicitation materials primarily via the Internet, rather than mailing paper copies of these materials to each stockholder. On or about April 28, 2026, we will mail to each stockholder a Notice of Internet Availability of Proxy Materials with instructions on how to access the proxy materials, vote, and request paper copies.

You are cordially invited to attend the Annual Meeting; however, whether or not you expect to attend the Annual Meeting via the Annual Meeting Website, you are urged to submit your proxy so that your shares of stock may be represented and voted in accordance with your preferences and in order to help establish the presence of a quorum at the Annual Meeting. You can vote your shares via the Internet, by a toll-free telephone call, or by properly completing, signing and returning a hard copy of the proxy card, which can be requested by following the instructions on the Notice of Internet Availability of Proxy Materials. Stockholders of record who attend the Annual Meeting and would like to vote at the Annual Meeting via the Annual Meeting Website may do so even if they have already submitted their proxy.

Pursuant to the rules of the New York Stock Exchange, if you hold your shares in street name, brokers, banks or other nominees will not have discretion to vote your shares on the election of directors, the advisory vote on executive compensation, and the amendment to the 2019 Plan. We encourage you to provide voting instructions to your broker, bank or other nominee if you hold your shares in street name so that your voice is heard on such matters.

Important Notice Regarding the Availability of Proxy Materials for the Stockholders Meeting to be held on June 11, 2026: This Notice of Annual Meeting, the Company’s Proxy Statement and the 2025 Annual Report to Stockholders are available free of charge at www.proxydocs.com/snda.
