Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Organization and Business Sonida Senior Living, Inc., a Delaware corporation (together with its subsidiaries, the “Company,” “we,” “our,” “us,” or “Sonida”), is a leading owner, operator and investor in independent living, assisted living and memory care communities and services for senior adults in the United States in terms of resident capacity. The Company owns, operates, manages and invests in senior housing communities throughout the United States. As of March 31, 2025, the Company owned, managed or invested in 94 senior housing communities in 20 states with an aggregate capacity of approximately 10,000 residents1, including 81 owned senior housing communities (including four owned through joint venture investments in consolidated entities, four owned through a joint venture investment in an unconsolidated entity, and one unoccupied) and 13 communities that the Company manages on behalf of a third-party. Principles of Consolidation The accompanying condensed consolidated financial statements include the financial statements of Sonida Senior Living, Inc., its wholly-owned subsidiaries, and other entities in which the Company has a controlling financial interest. All material intercompany balances and transactions have been eliminated in consolidation. The Company reports investments in unconsolidated entities over whose operating and financial policies it has the ability to exercise significant influence under the equity method of accounting. The Company evaluates its potential variable interest entity (“VIE”) relationships under certain criteria as provided for in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”). ASC 810 broadly defines a VIE as an entity with one or more of the following characteristics: (a) the total equity investment at risk is insufficient to finance the entity's activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about the entity's activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity's activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. The Company performs this evaluation on an ongoing basis and consolidates any VIEs for which the Company is determined to be the primary beneficiary, as determined by the Company's power to direct the VIEs activities and the obligation to absorb its losses or the right to receive its benefits, which are potentially significant to the VIE. As of March 31, 2025, the Company has a joint venture, Stone JV LLC (“Stone JV”) which is treated as an unconsolidated entity. See “Note 3–Investments.” As of March 31, 2025, the Company was a 51% owner in two joint ventures (collectively, the “Palatine JVs”) with affiliates of Palatine Capital Partners. The Company has evaluated its investment in the Palatine JVs under ASC 810. The Company has determined that it has the power to direct the activities of the VIE that most significantly impact its economic performance and is the primary beneficiary of the VIE in accordance with ASC 810. Accordingly, the Company has consolidated the activity of the Palatine JVs into its consolidated financial statements for the periods ended March 31, 2025 and December 31, 2024. Interim Unaudited Financial Information The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been omitted from this Quarterly Report on Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The results for the interim periods shown in this report are not necessarily indicative of future financial results. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, including normal recurring items, necessary to present fairly our condensed consolidated financial position as of March 31, 2025 and December 31, 2024, and our condensed consolidated results of operations and cash flows for the periods ended March 31, 2025 and 2024. Reclassifications Certain amounts previously reflected in the prior year condensed consolidated financial statements have been reclassified to conform to our March 31, 2025 presentation. The condensed consolidated statements of operations as of March 31, 2024 reflects reclassifying transaction, transition and restructuring costs from “General and administrative expense” to “Transaction, transition and restructuring costs.” Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. These estimates include such items related to the accounting for: income taxes, including assessments of probabilities of realization of income tax benefits; other contingencies; allowances for uncollectible accounts receivable; impairment of long-lived assets, including applicable cash flow projections, holding periods and fair value evaluations; stock-based compensation; fair values of assets and liabilities acquired in asset acquisitions, fair values of our equity method investments; and depreciation and amortization, including determination of estimated useful lives. Actual results could differ from those estimates.
