This Amendment No. 9 to the Schedule 13D (this "Amendment No. 9") relates to the common stock, par value $0.01 per share (the "Common Stock"), of Sonida Senior Living, Inc., a Delaware corporation (the "Issuer"), and amends the Schedule 13D filed by the Reporting Persons (as defined below) on March 25, 2021 (the "Original Schedule 13D"), as amended by each of Amendment No. 1 filed on June 9, 2021 ("Amendment No. 1"), Amendment No. 2 filed on August 9, 2021 ("Amendment No. 2"), Amendment No. 3 filed on August 12, 2021 ("Amendment No. 3"), Amendment No. 4 filed on September 15, 2021 ("Amendment No. 4"), Amendment No. 5 filed on October 12, 2021 ("Amendment No. 5"), Amendment No. 6 filed on November 5, 2021 ("Amendment No. 6"), Amendment No. 7 filed on November 30, 2021 ("Amendment No. 7"), and Amendment No. 8 filed on December 5, 2022 ("Amendment No. 8") (together, with the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3, Amendment No. 4, Amendment No. 5, Amendment No. 6, Amendment No. 7, and Amendment No. 8 the "Schedule 13D"). Any capitalized terms used and not defined in this Amendment No. 8 have the meanings set forth in the Schedule 13D.

This Amendment No. 9 is being filed to report a greater than 1% increase in the percentage of shares of Common Stock beneficially owned by the Reporting Persons and to amend Item 3 and Item 5 of the Schedule 13D to reflect such transactions. Except as amended hereby, all statements and disclosures in the Schedule 13D remain accurate as of the date of this Amendment No. 9.

### Item 3. Source and Amount of Funds or Other Consideration
Item 3 of the Schedule 13D is hereby amended and restated in its entirety as follows:

Hudson Investors, Ltd., incorporated under the laws of the British Virgin Islands ("<u>Hudson</u>"), has expended an aggregate of approximately $6,148,567 of its investment capital to acquire the 268,630 shares of Common Stock beneficially owned by Hudson, and Pangaea Ventures, L.P., a Delaware limited partnership ("<u>Pangaea</u>"), has expended an aggregate of approximately $12,442,178 of its investment capital to acquire the 408,148 shares of Common Stock beneficially owned by Pangaea. As of the filing date of this Amendment No. 9, the Reporting Persons, in total, beneficially own 676,778 shares of Common Stock (the "<u>Shares</u>").

Item 5. Interest in Securities of the Issuer

Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) (b) As of the filing date of this Amendment No. 9, the Shares represent approximately 10.15% of the outstanding shares of Common Stock. Percentages of the shares of Common Stock outstanding reported in this Amendment No. 9 are calculated based upon 6,669,949 shares of Common Stock outstanding, as reported in the Issuer's Quarterly Report on Form 10-Q filed with the U.S. Securities and Exchange Commission ("SEC") on November 14, 2022. Ortelius Advisors, L.P., a Delaware limited partnership ("<u>OA</u>"), has voting and dispositive power over the Shares held by Pangaea, and through ownership and control, Mr. DeSorcy has voting and dispositive power over portfolios managed by OA. Ortelius Capital Partners, LLC, a Delaware limited liability company ("<u>OC</u>"), has voting and dispositive power over the Shares held by Hudson, and, in turn, as the control person of OC, Mr. DeSorcy has voting and dispositive power over the Shares held by Hudson.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Set forth on Schedule A hereto are all transactions in the securities of the Issuer effected since the filing of Amendment No. 8 to the Schedule 13D by any Reporting Person, inclusive of any transactions effected through January 24, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Other than Pangaea and Hudson that beneficially hold the Shares as identified in this Schedule 13D, and except as set forth in this Item 5, no other person is known to have the right to receive, or the power to direct the receipt of, dividends from or proceeds from the sale, of the Shares beneficially owned by Pangaea or Hudson.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Not applicable.

**SIGNATURE**

After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
