CHP Merger	CHP Merger Strategic Merger with CNL Healthcare Properties, Inc. On March 11, 2026, pursuant to a definitive agreement and plan of merger dated November 4, 2025 (the “Merger Agreement”), by and among the Company, SSL Sparti LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company (“Holdco”), SSL Sparti Property Holdings Inc., a Maryland corporation and a wholly owned subsidiary of Holdco (f/k/a Sparti Merger Sub, Inc., “SNDA Merger Sub”), CNL Healthcare Properties, Inc., a Maryland corporation (“CHP”), and CHP Merger Corp., a Maryland corporation and a wholly owned subsidiary of CHP (“CHP Merger Sub”), the Company completed the acquisition of CHP through a series of steps ending with a forward merger of CHP with and into SNDA Merger Sub, with SNDA Merger Sub surviving the merger (the “CHP Merger”). As a result of the CHP Merger, the Company acquired 100% of the outstanding shares of CHP. The transactions contemplated by the Merger Agreement are collectively referred to herein as the “Merger Transactions”. Pursuant to the Merger Agreement, each share of common stock of CHP, par value $0.01, was cancelled and converted into the right to receive (i) $2.32 in cash and 0.1318 shares of common stock of the Company, par value $0.01 (“Sonida Common Stock”), which was determined by dividing (a) $4.58 by (b) the volume weighted average trading price (“VWAP”), of Sonida Common Stock during a measurement period prior to the closing date, subject to a collar of 15% below the transaction reference price for the Sonida Common Stock of $26.74 (the “Transaction Reference Price”) and 30% above the Transaction Reference Price. Since the VWAP during the measurement period was $35.93, the 0.1318 exchange ratio was calculated by dividing $4.58 by $34.76, being the high end of the collar. In connection with the issuance of Sonida Common Stock to the former CHP shareholders and certain equity financing transactions, on February 26, 2026, the Company amended its Amended and Restated Certificate of Incorporation, pursuant to that certain Eighth Certificate of Amendment to the Amended and Restated Certificate of Incorporation, to increase the authorized number of shares of Sonida Common Stock to 100.0 million. On November 5, 2025, the Company provided an irrevocable standby letter of credit in the amount of $15.0 million to CHP in partial support of a potential termination fee if needed. As of December 31, 2025, the $15.0 million letter of credit was outstanding with an interest rate of 2.5%. On March 11, 2026, the standby letter of credit was cancelled in conjunction with the closing of the Merger Transactions. Financing of the Merger Transactions On December 29, 2025, the Company amended and restated its revolving credit facility (as further amended on March 5, 2026, the “A&R Credit Agreement”) to, among other things, provide for permanent debt financing (“Permanent Financing”) to fund a portion of the cash consideration necessary for the CHP Merger, which amendments were subject to and conditioned upon the consummation of the CHP Merger. The A&R Credit Agreement increased the available commitments under the revolving credit facility to $405 million, extended the maturity thereof to March 10, 2030, reduced the leverage-based pricing matrix to between Secured Overnight Financing Rate (“SOFR”) plus 1.35% margin and SOFR plus 2.00% margin, expanded the lenders, and effected certain other changes (the “New Revolving Credit Facility”). In addition, under the A&R Credit Agreement, the Company incurred $525 million in new term loans in two equal tranches (the “Term Loan Facility”). The Term Loan Facility is comprised of a three-year tranche that matures March 10, 2029 and a five-year tranche that matures March 10, 2031. The Term Loan Facility is subject to a leverage-based pricing matrix between SOFR plus 1.30% margin and SOFR plus 1.95% margin. The A&R Credit Agreement has a $320 million accordion feature to provide for future liquidity needs of the Company. The Company entered into a SOFR-based interest rate cap (“IRC”) to reduce exposure to the variable interest rate fluctuations associated with the Term Loan Facility. The IRC has a total cost of $0.6 million, an aggregate notional amount of $262.5 million, a 36-month term and an interest rate of 4.50%. On March 10, 2026, in order to fund the remaining portion of the cash consideration required for the CHP Merger, the Company incurred $270.0 million in loans under a 364-day senior secured bridge loan (the “Bridge Facility”). The Bridge Facility matures on March 9, 2027 and is subject to a leverage-based pricing matrix between SOFR plus 1.35% margin and SOFR plus 2.00% margin. The Permanent Financing and the Bridge Facility are subject to customary guarantees and security provisions, events of default, corporate covenants and borrowing base availability requirements. The Company entered into a SOFR-based IRC to reduce exposure to the variable interest rate fluctuations associated with the Bridge Facility. The IRC has a total cost of $35 thousand, an aggregate notional amount of $270 million, a 12-month term and an interest rate of 4.25%. See “Note 9–Debt” in the Notes to Consolidated Financial Statements. In connection with the Merger Transactions, the Company has incurred and accrued deferred costs of $13.2 million which are included in Deferred costs on the consolidated balance sheets as of December 31, 2025. Equity Financing On November 4, 2025, Sonida entered into (i) an investment agreement (the “Conversant Investment Agreement”) with certain affiliates of Conversant (the “Conversant Investors”), pursuant to which the Conversant Investors agreed to fund an aggregate amount of $100.0 million in exchange for the issuance of 3,739,716 shares of Sonida Common Stock in a private placement pursuant to Section 4(a)(2) of the Securities Act at $26.74 per share, immediately prior to the CHP Merger, and (ii) an investment agreement (the “Silk Investment Agreement” and, together with the Conversant Investment Agreement, collectively, the “Investment Agreements”) with Silk (the Conversant Investors and Silk, together, the “Equity Investors”) pursuant to which Silk agreed to fund an aggregate amount of $10.0 million in exchange for the issuance of 373,972 shares of Sonida Common Stock in a private placement at $26.74 per share on substantially the same terms as in the Conversant Investment Agreement (collectively, the “Equity Financing”). On March 11, 2026, the Company issued 4,113,688 shares of Sonida Common Stock to the Equity Investors. Sonida used the proceeds from the Equity Financing pursuant to the Investment Agreements to fund a portion of the cash consideration required for the consummation of the transactions under the Merger Agreement. Under the Investment Agreements, Sonida provided to the Equity Investors representations and warranties substantially similar to those under the Merger Agreement, and the Equity Investors provided to Sonida customary representations and warranties for a private financing of this type. The Equity Investors and Sonida are subject to compliance with customary covenants under the Investment Agreements, subject to the Equity Investors’ consent (not to be unreasonably withheld, conditioned or delayed). The parties have provided mutual indemnities for breach of certain representation and warranties and post-closing covenants capped at the applicable purchase price paid by each of the Equity Investors. Under the Investment Agreements, Sonida was responsible for the Equity Investors’ reasonable and documented legal and other out-of-pocket expenses in connection with the Equity Financing (not to exceed, $2.0 million with respect to the Conversant Investors and $0.2 million with respect to Silk).
