Accounting Policies [Abstract]
Nature of Operations and Significant Accounting Policies	Nature of Operations and Significant Accounting Policies Nature of operations: Lincoln International, Inc. (the “Parent”), a Delaware corporation, together with its consolidated domestic and foreign subsidiaries and affiliates (collectively, the “Company”), is a multinational investment banking advisory firm focused on the private capital markets. The Company provides merger and acquisition advisory, capital advisory, private funds advisory, valuation advisory and other related services to private equity firms, public corporations, and privately-owned companies worldwide. The Company offers its services through more than thirty offices across fourteen countries throughout the Americas, Europe, the Middle East and Asia. On May 21, 2026, the Parent closed its initial public offering (the “IPO”). The Parent received net proceeds of $440.5 million and the selling stockholders received net proceeds of $9.8 million, in each case after the full exercise of the underwriters’ option and deducting the underwriting discount. In connection with the IPO, the Parent issued and sold 23,682,849 shares and the selling stockholders sold 524,637 shares of Class A common stock, par value $0.00001 per share (“Class A common stock”), at an offering price of $20.00 per share. The Company also completed certain organizational transactions (the “Organizational Transactions”), pursuant to which the Parent received a controlling interest in Lincoln International, LP (“LILP”). The Organizational Transactions did not result in a change in the carrying value of the net assets of LILP. The interim financial information provided in the accompanying condensed consolidated financial statements represents the financial condition and results of operations prior to the Organizational Transactions and IPO along with the consolidated financial condition and results of operations subsequent to the Organizational Transactions and IPO. For additional information on the Organizational Transactions and IPO refer to Note 2. The Parent is a holding company whose principal asset consists of the outstanding common units of ownership of LILP. The remaining common units of LILP are held by the limited partners of LILP other than the Parent (the “LILP Partners”). As the sole general partner of LILP, the Parent controls the business and affairs of LILP and its direct and indirect subsidiaries. Basis of Presentation and Accounting policies: The Company follows accounting principles generally accepted in the United States of America (“GAAP”) as established by the Financial Accounting Standards Board (the “FASB”) to ensure consistent reporting of financial condition, results of operations, and cash flows. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission in Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In management’s opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the results for the interim periods presented. Interim results are not necessarily indicative of full year results. The unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements for Lincoln International, LP, for the year ended December 31, 2025 included in the Company’s final prospectus dated May 19, 2026 and filed with the Securities and Exchange Commission on May 21, 2026 (the “Prospectus”). The accompanying unaudited condensed consolidated financial statements include the accounts of the Parent and its subsidiary, LILP, and its subsidiaries, that the Parent controls due to ownership of common units of LILP and as its sole general partner. All intercompany transactions and balances have been eliminated in consolidation. Accordingly, the Company has prepared these accompanying unaudited condensed consolidated financial statements in accordance with Accounting Standards Codification (“ASC”) Topic 810, Consolidation. The Company reports a noncontrolling interest representing the economic interest in LILP held by the LILP Partners. The earnings attributable to the noncontrolling interest presented in the unaudited condensed consolidated statements of comprehensive income (loss) represents the portion of earnings attributable to that economic interest. In connection with the Organizational Transactions, we entered into a Tax Receivable Agreement with LILP, certain LILP Partners and the other eligible parties named therein. Amounts payable under the Tax Receivable Agreement, and the related deferred tax assets, are recorded based on estimates of the tax benefits we expect to realize from the basis adjustments and interest deductions, which requires significant management judgment. Because of these judgments, the actual amount and timing of payments under the Tax Receivable Agreement could differ materially from our estimates. See Note 23 of the notes to condensed consolidated financial statements for additional information. Other than the foregoing, during the six months ended June 30, 2026, no other material changes have been made to our significant accounting policies and estimates from those described in Note 1 of the audited consolidated financial statements for the year ended December 31, 2025 included in the Prospectus. Recently Issued Accounting Pronouncements (Not Yet Adopted) In December 2025, the FASB issued Accounting Standards Update (“ASU”) 2025-11, Narrow-Scope Improvements. ASU 2025-11 clarifies the current interim disclosure requirements and the applicability of ASC 270, Interim Reporting by creating a comprehensive list of required interim disclosures and adding a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The guidance is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. Additionally, in July 2025, the FASB issued ASU No. 2025-05 Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses for Accounts Receivable and Contract Assets. The guidance is effective for annual periods beginning after December 15, 2025. The Company is evaluating the effects of adopting this new accounting guidance. In November 2024, FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU aims to build a better understanding of an entity’s expenses through more detailed tabular disclosures surrounding certain costs and expenses (including but not limited to employee compensation, amortization of intangibles, and depreciation), defining and disclosing selling expense, and qualitatively describing remaining amounts not disaggregated in relevant expense captions. In addition, certain existing expense disclosures will be required to be presented within the same note and tabular format as prescribed by ASU No. 2024-03. The new guidance will be effective for annual periods beginning after December 15, 2026 and interim periods beginning after December 15, 2027 and can be applied on a prospective or retrospective basis. The Company is evaluating the effects of adopting this new accounting guidance. In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 requires consistent categories and greater disaggregation of information in the effective income tax rate reconciliation disclosure in addition to disaggregated reporting of income taxes paid by jurisdiction. ASU 2023-09 also amends certain other current disclosure and information reporting requirements. For emerging growth companies, the guidance will be effective for annual periods beginning after December 15, 2025. The Company is evaluating the effects of adopting this new accounting guidance.
