Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Basis of Presentation	Business and Basis of Presentation The Baldwin Insurance Group, Inc. was incorporated in the state of Delaware on July 1, 2019 as BRP Group, Inc. and, on May 2, 2024, was renamed The Baldwin Insurance Group, Inc. The Baldwin Insurance Group, Inc. is a holding company and sole managing member of The Baldwin Insurance Group Holdings, LLC (“Baldwin Holdings”) and its sole material asset is its ownership interest in Baldwin Holdings, through which all of its business has been and is conducted. In these condensed consolidated financial statements, unless the context otherwise requires, the words “Baldwin,” and the “Company” refer to The Baldwin Insurance Group, Inc., together with its consolidated subsidiaries, including Baldwin Holdings and its consolidated subsidiaries and affiliates. Baldwin is a diversified insurance agency and services organization that markets and sells insurance products and services to its clients throughout the U.S. A significant portion of the Company’s business is concentrated in the Southeastern U.S., with several other regional concentrations. Baldwin and its subsidiaries operate through three reportable segments (“operating groups”), including Insurance Advisory Solutions, Underwriting, Capacity & Technology Solutions and Mainstreet Insurance Solutions, which are discussed in more detail in Note 18. Principles of Consolidation The consolidated financial statements include the accounts of Baldwin and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. As the sole manager of Baldwin Holdings, Baldwin operates and controls all the business and affairs of Baldwin Holdings, and has the sole voting interest in, and controls the management of, Baldwin Holdings. Accordingly, Baldwin consolidates Baldwin Holdings in its consolidated financial statements, resulting in a noncontrolling interest related to the membership interests of Baldwin Holdings (the “LLC Units”) held by Baldwin Holdings’ members in the Company’s consolidated financial statements. The Company has prepared these condensed consolidated financial statements in accordance with Accounting Standards Codification (“ASC”) Topic 810, Consolidation (“Topic 810”). Topic 810 requires that if an enterprise is the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity should be included in the consolidated financial statements of the enterprise. The Company has recognized certain entities as variable interest entities, of which the Company is the primary beneficiary, and has included the accounts of these entities in the consolidated financial statements. Refer to Note 4 for additional information regarding the Company’s variable interest entities. Topic 810 also requires that the equity of a noncontrolling interest shall be reported on the condensed consolidated balance sheets within total equity of the Company. Certain redeemable noncontrolling interests are reported on the condensed consolidated balance sheets as mezzanine equity. Topic 810 also requires revenues, expenses, gains, losses, net income or loss, and other comprehensive income or loss to be reported in the consolidated financial statements at consolidated amounts, which include amounts attributable to the owners of the parent and the noncontrolling interests. Unaudited Interim Financial Reporting The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Accordingly, they do not include all the information and related notes required by GAAP for complete consolidated financial statements. In the opinion of management, all adjustments, consisting of recurring accruals, considered necessary for fair presentation of the financial statements have been included. The condensed consolidated balance sheet for the year ended December 31, 2025 was derived from audited financial statements, but does not include all disclosures required by GAAP. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 26, 2026. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates. Significant estimates underlying the accompanying condensed consolidated financial statements include the application of guidance for revenue recognition, impairment of intangible assets and goodwill, the valuation of acquired relationships, the valuation of contingent consideration and the Tax Receivable Agreement liabilities. Recently Issued Accounting Standards In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)—Disaggregation of Income Statement Expenses (“ASU 2024-03”) to improve the disclosures about a public business entity’s expenses and supply more detailed information about the types of expenses in commonly presented expense captions. These expense captions include purchases of inventory, employee compensation, depreciation, amortization, and depletion in commonly presented expense captions such as cost of sales, selling, general and administrative expense, and research and development. This guidance is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The Company expects the adoption of this standard to expand its expense disclosures, but otherwise have no impact on the consolidated financial statements. In May 2025, the FASB issued ASU No. 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity (“ASU 2025-03”). This ASU amends the guidance for identifying the accounting acquirer in a business combination effected primarily by exchanging equity interests when the legal acquiree is a variable interest entity (“VIE”) that meets the definition of a business. Under the new guidance, entities must consider the factors in ASC 805-10-55-12 through 55-15—such as relative voting rights, composition of the governing body and management, and size of the combining entities—regardless of whether the legal acquiree is a VIE. This change is intended to improve consistency and comparability in financial reporting for economically similar transactions. The guidance is effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual periods, with early adoption permitted. The Company will apply the amendments prospectively to business combinations occurring after the initial application. The Company expects the adoption of this standard to change how it evaluates the accounting acquirer in future business combinations involving a VIE, but otherwise have no impact on the consolidated financial statements. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software (“ASU 2025-06”). ASU 2025-06 updates the accounting framework for internal-use software development costs to better reflect modern development practices, including agile methodologies. Key changes include replacing the traditional project stage model with a capitalization threshold based on management’s authorization and commitment to fund the project, along with a requirement that completion of the project be probable. ASU 2025-06 also supersedes guidance on website development costs. This guidance is effective for fiscal years beginning after December 15, 2027 and interim periods within those fiscal years. The Company is currently evaluating the impact this standard will have on the consolidated financial statements. Changes in Presentation Certain prior year amounts have been reclassified to conform to current year presentation. These reclassifications had no impact on the Company’s previously reported consolidated financial position, results of operations or cash flows.
