Organization, Consolidation and Presentation of Financial Statements [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements are presented in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). The accompanying consolidated financial statements include the results of operations of the Company and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. All dollar amounts are in millions, unless otherwise noted. Share and per share amounts are presented on a post-conversion basis for all periods presented, unless otherwise noted. The Company's significant accounting policies are detailed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC (the "2025 Annual Report"). Interim Financial Statements The accompanying consolidated financial statements have been prepared in accordance with U.S. GAAP and Article 10 of Regulation S-X of the SEC for interim financial information and should be read in conjunction with the 2025 Annual Report. The financial statements presented in this Quarterly Report on Form 10-Q are unaudited; however, in the opinion of management, the financial statements reflect all adjustments, consisting solely of normal, recurring adjustments, necessary for the fair presentation of the financial statements for the periods presented. The results disclosed in the condensed consolidated financial statements as of and for the six months ended June 30, 2026 are not necessarily indicative of the results to be expected for the full year. Use of Estimates The preparation of the consolidated financial statements requires management to make a number of estimates and assumptions relating to the reported amount of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the period. The Company bases its estimates on historical experience, current business factors and various other assumptions believed to be reasonable under the circumstances, all of which are necessary in order to form a basis for determining the carrying values of assets and liabilities. Actual results may differ from those estimates and assumptions. The Company evaluates the adequacy of its reserves and the estimates used in calculations on an on-going basis. Significant areas requiring management judgment and estimates include the valuation of equity and liability classified stock‑based compensation awards, including stock options, restricted stock units, and performance‑based awards; the determination of fair value and probability‑of‑achievement assumptions for performance conditions; valuation allowances on deferred tax assets based on an assessment of recoverability against future taxable income; and estimates of the inputs used to calculate the tax receivable agreement ("TRA") liability. Variable Interest Entities The Company evaluates its contractual, ownership, and other interests in entities to determine if it has a variable interest in a variable interest entity (“VIE”) in accordance with ASC 810, Consolidation (“ASC 810”). A VIE is an entity that either lacks sufficient equity to permit it to finance its activities without additional subordinated financial support or for which the equity investors do not have characteristics of a controlling financial interest. These evaluations are complex and involve significant judgment. If the Company determines that an entity in which it holds a contractual or ownership interest is a VIE and that the Company is the primary beneficiary, the Company consolidates such entity in its consolidated financial statements. The primary beneficiary of a VIE is generally the party that meets both of the following criteria: (i) has the power to direct activities that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Management performs ongoing reassessments of whether changes in the facts and circumstances regarding the Company’s involvement with a VIE will cause the consolidation conclusion to change. Changes in consolidation status are applied prospectively. Equity Method Accounting Presentation for GPGI Holdings The Company has a variable interest in GPGI Holdings, the Company’s wholly owned operating subsidiary. GPGI Holdings is considered a VIE as GPGI, Inc. is the sole holder of GPGI Holdings’ equity investment at risk but is not able to direct the activities that most significantly impact GPGI Holdings’ economic performance. Effective as of February 28, 2025, the date of the Spin-Off of Resolute Holdings, and as a result of GPGI Holdings entering into the CompoSecure Management Agreement with Resolute Holdings, the Company determined that GPGI Holdings is a VIE for which the Company is not the primary beneficiary. Therefore, the results of operations and cash flows of the Company's wholly owned subsidiary, GPGI Holdings, and the operating companies which are its subsidiaries, are not consolidated in the financial statements included in this report and are instead accounted for under the equity method of accounting. Under the equity method of accounting, the financial information of GPGI Holdings is not reflected within the Company’s consolidated financial statements. The Company’s share of the earnings of GPGI Holdings is reported in a single line item within the Company’s consolidated statements of operations and cash flows as earnings (losses) in equity method investment. The carrying value of the Company's investment in GPGI Holdings is reported in the Company’s consolidated balance sheets as an equity method investment. This equity method investment is increased (decreased) by the Company's share of the earnings (losses) of GPGI Holdings and is also decreased by the Company’s share of dividends declared by GPGI Holdings from time to time, if any. No gain or loss was recognized upon deconsolidation of GPGI Holdings as an equity method investment because Resolute Holdings and the Company were both under common control at the date of the Spin-Off and execution of the CompoSecure Management Agreement. Distributions received from equity method investees are classified in the consolidated statements of cash flows using the cumulative earnings approach. Under this method, distributions received are classified as operating cash inflows to the extent they represent a return on investment based on cumulative equity earnings recognized, adjusted for the amortization of basis differences. Distributions in excess of cumulative adjusted equity earnings are considered a return of investment and are classified as investing cash inflows. Effective upon the closing of the Husky Transaction, and as a result of Husky entering into the Husky Management Agreement with Resolute Holdings, GPGI Holdings determined that it does not have the power to direct the activities that most significantly impact Husky’s economic performance and is therefore not the primary beneficiary. As a result, Husky is not consolidated by GPGI Holdings and is accounted for under the equity method of accounting, under which GPGI Holdings’ share of Husky’s earnings or losses is reflected in a single line item in GPGI Holdings’ results of operations and the carrying value of the investment is adjusted accordingly. For GPGI, this activity is included within earnings (losses) in equity method investment related to GPGI Holdings, which represents GPGI’s share of earnings or losses from its equity method investment in GPGI Holdings. Treasury Stock The Company’s stock repurchase program authorizes the Company to repurchase shares in open market and/or private transactions from time to time based on numerous factors, including, but not limited to, share price and other market conditions, the Company’s ongoing capital allocation planning, cash and debt levels, and other demands for cash. The Company records the shares repurchased as treasury stock based on the amount paid to repurchase such shares. Direct costs incurred to acquire treasury stock are classified as financing activities in the consolidated statements of cash flows. The ultimate use of the repurchased shares has not been determined, therefore, the repurchased shares are presented in the Company's consolidated financial statements as a reduction to shareholders' equity (deficit). See Note 4 - Equity Structure for further information on the repurchase of shares. Net Income (Loss) Per Share The Company complies with the accounting and disclosure requirements of ASC 260, Earnings Per Share. Income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. The weighted-average number of common shares outstanding during the period consists of Class A Common Stock. Diluted net loss per share is computed by dividing the net loss allocated to potentially dilutive instruments attributable to controlling interest by the basic weighted-average number of shares of common stock outstanding during the period, adjusted for the potentially dilutive shares of common stock equivalents resulting from the assumed exercise of the warrants, payment of the earnout consideration shares, exercise and vesting of equity awards only if the effect is not anti-dilutive. Fair Value Measurements The Company determines fair value in accordance with ASC 820, Fair Value Measurement, which established a hierarchy for the inputs used to measure the fair value of financial assets and liabilities based on the source of the inputs, which generally range from quoted prices for identical instruments in a principal trading market to estimates determined using significant unobservable inputs. The fair value hierarchy prioritizes the inputs, which refer to assumptions that market participants would use in pricing an asset or liability, based upon the highest and best use, into three levels as follows: The standard describes three levels of inputs that may be used to measure fair value: •Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. •Level 2: Observable inputs other than unadjusted quoted prices in active markets for identical assets or liabilities such as: ◦Quoted prices for similar assets or liabilities in active markets ◦Quoted prices for identical or similar assets or liabilities in inactive markets ◦Inputs other than quoted prices that are observable for the asset or liability ◦Inputs that are derived principally from or corroborated by observable market data by correlation or other mean •Level 3: Unobservable inputs in which there is little or no market data available, which are significant to the fair value measurement and require the Company to develop its own assumptions. The Company’s financial assets and liabilities measured at fair value consisted of cash and cash equivalents, accounts receivable, accounts payable and debt. Cash and cash equivalents consisted of bank deposits and short-term investments, such as money market funds, the fair value of which is based on quoted market prices, a Level 1 fair value measure. As of June 30, 2026 and December 31, 2025, the carrying values of cash, cash equivalents, accounts receivable and accounts payable approximate fair value because of the short-term maturity of these instruments. Recently Issued Accounting Pronouncements Not Yet Adopted In December 2025, the FASB issued Accounting Standards Update No. 2025‑11, Interim Reporting (Topic 270): Narrow‑Scope Improvements (“ASU 2025‑11”), which clarifies and updates interim reporting requirements under ASC 270. The amendments aim to improve consistency and decision‑usefulness by refining the objective of interim reporting and clarifying required updates for significant events and changes occurring during interim periods. For public business entities ("PBEs"), ASU 2025‑11 is effective for interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of ASU 2025-11 on its consolidated financial statements. On September 29, 2025, the FASB released Accounting Standards Update No. 2025-07, Scope Refinements for Derivatives and Share-Based Noncash Consideration (“ASU 2025-07”), which amends ASC 815 and ASC 606. ASU 2025-07 revises the guidance in ASC 815 and ASC 606 to clarify that the update was issued to reduce complexity and diversity in practice by: (1) refining the application of derivative accounting for contracts with entity-specific reference terms; and (2) clarifying the accounting for share-based noncash consideration in revenue arrangements. For all entities, ASU 2025-07 will become effective for annual reporting periods beginning after December 15, 2026, including interim reporting periods within those annual reporting periods. The Company is currently assessing the impact that the adoption of this ASU will have on the Company's consolidated financial statements. On November 4, 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires disaggregated disclosure of income statement expenses for PBEs. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for all PBEs for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027 and early adoption is permitted. On January 7, 2025, the FASB released ASU 2025-01 which revises the effective date of ASU 2024-03 “to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027.” The Company is assessing the impact that the adoption of this ASU will have on the Company's consolidated financial statements.
