Nature of Operations and Basis of Presentation	Nature of Operations and Basis of Presentation Organization Legence Corp. was incorporated as a Delaware corporation on January 9, 2025 as a holding company for the purpose of facilitating an initial public offering (“IPO”) and other related transactions in order to carry on the business of Legence Holdings LLC (“Legence Holdings”). Legence Holdings and its subsidiaries are a leading provider of engineering, installation and maintenance services for mission-critical systems in buildings. The Company focuses on high-growth sectors that have technically demanding buildings, including technology, life sciences, healthcare and education. The Company specializes in designing, fabricating and installing complex heating, ventilation and air conditioning (“HVAC”), process piping and other mechanical, electrical and plumbing (“MEP”) systems for new facilities and upgrading HVAC, lighting and building controls in existing facilities to enhance building performance, improve reliability and drive efficiency. Services are primarily provided on a fixed price basis. All references to the “Company” or “Legence” in this report are to Legence Corp. and its consolidated subsidiaries. Initial Public Offering and Organizational Transactions On September 15, 2025, the Company completed its IPO. In connection with the IPO, the Company completed a corporate reorganization (the “Corporate Reorganization”) that established an UP-C structure in which Legence Corp. became the managing member of Legence Holdings, Legence Holdings interests were recapitalized into LGN A Units and LGN B Units (collectively, “LGN Units”), Legence Parent II LLC (“Legence Parent II”), Legence Parent Management Aggregator LLC (“Management Aggregator I”) and Legence Parent II Management Aggregator LLC (“Management Aggregator II,” and together with Management Aggregator I, the “Management Aggregators”) were formed, and Legence Parent LLC (“Legence Parent”) subscribed for Class B common stock (“Class B Common Stock”) for nominal consideration and retained a portion of its pre-IPO ownership in Legence Holdings through LGN B Units. The number of LGN A Units corresponds on a one-for-one basis with shares of the Company’s Class A common stock, par value $0.01 (the “Class A Common Stock”), while the number of LGN B Units corresponds on a one-for-one basis with shares of the Company’s Class B Common Stock. Class A Common Stock (corresponding to LGN A Units) is held by Legence Parent and Legence Parent II (through their respective wholly-owned subsidiaries, since the fourth quarter of 2025, as described below) and public shareholders. The Corporate Reorganization was accounted for in a manner consistent with a reorganization of entities under common control. The unaudited Condensed Consolidated Financial Statements for periods prior to the IPO and Corporate Reorganization relate to Legence Holdings. Prior to the Corporate Reorganization, Legence Corp. had no operations. Additionally, as part of the Corporate Reorganization, Legence Corp. entered into an exchange agreement (the “Exchange Agreement”) in which the holders of LGN B Units may exchange their LGN B Units, together with an equal number of corresponding shares of Class B Common Stock, for shares of Class A Common Stock of Legence Corp. on a one-for-one basis or the cash equivalent thereof (based on the 10-day volume weighted average price of the shares of Class A Common Stock at the time of exchange) as determined by Legence (the “Exchange Right”). If the Company elects the exchange to be settled in cash, the cash used to settle the redemption must be funded through a private sale or public offering of Class A Common Stock. In the fourth quarter of 2025, Legence Parent and Legence Parent II formed Legence Parent ML LLC and Legence Parent II ML LLC (together, the “ML Entities”), which now hold the interests in Legence Holdings and Legence Corp. previously held by Legence Parent and Legence Parent II (collectively, the “Parent Entities”). The accompanying unaudited Condensed Consolidated Financial Statements were prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these unaudited Condensed Consolidated Financial Statements do not include all information or notes required by GAAP for annual financial statements and should be read together with the Company’s audited Consolidated Financial Statements and notes thereto from the Form 10-K for the year ended December 31, 2025, filed with the SEC on March 30, 2026 (the “2025 Annual Report”). In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements include all adjustments (consisting of normal recurring adjustments) that are necessary for a fair presentation of the Company’s financial position, results of operations, comprehensive income (loss) and cash flows for the interim periods presented. The December 31, 2025 Condensed Consolidated Balance Sheet data was derived from the 2025 audited Consolidated Financial Statements but does not include all disclosures required by GAAP. The preparation of the unaudited Condensed Consolidated Financial Statements requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the related revenues and expenses and disclosures as of the date of the financial statements. Actual results could differ from those estimates. Results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that will be realized for the year ended December 31, 2026, or for any future period. These condensed consolidated financial statements should be read in conjunction with the 2025 Annual Report.
