Organization and Basis of Presentation Disclosures	ORGANIZATION AND BASIS OF PRESENTATION Organization and Description of the Business LGI Homes, Inc., a Delaware corporation (the “Company”, “we,” “us,” or “our”), is headquartered in The Woodlands, Texas. We engage in the development of communities and the design, construction and sale of new homes in markets in Texas, Arizona, Florida, Georgia, New Mexico, Colorado, North Carolina, South Carolina, Washington, Tennessee, Minnesota, Oklahoma, Alabama, California, Oregon, Nevada, West Virginia, Virginia, Pennsylvania, Maryland and Utah. Basis of Presentation The unaudited consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments that are of a normal recurring nature and necessary for the fair presentation of our results for the interim periods presented. Results for interim periods are not necessarily indicative of results to be expected for the full year. The accompanying unaudited financial statements as of March 31, 2026, and for the three months ended March 31, 2026 and 2025, include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and these differences could have a significant impact on the financial statements. Recently Issued Accounting Pronouncements In November 2024, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” (“ASU 2024-03”), which requires disclosure of certain costs and expenses on an interim and annual basis in the notes to the financial statements. The amendments in this update are to be applied on a prospective basis, with the option for retrospective application. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the impact that this standard will have on our disclosures.
