SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). The consolidated financial statements for the prior periods include certain reclassifications that were made to conform to the current period presentation. Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly owned, after elimination of intercompany transactions and balances. Use of Estimates The preparation of financial statements in conformity with U.S. 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates made by management in connection with the preparation of the accompanying consolidated financial statements include the fair value of purchase consideration and assets acquired and liabilities assumed in a business combination, the useful lives of long-lived assets, the fair value of financial assets and liabilities, valuation of goodwill, indefinite life intangible assets, stock options, founder advisory fees, and realizability of deferred tax assets. Actual results could differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents consist of cash in banks. For purposes of reporting cash and cash equivalents, the Company considers all deposits with an original maturity of three months or less to be cash equivalents. The Company deposits cash with financial institutions that management believes is of high credit quality, and cash balances in bank accounts, at times, exceeds federally insured limits. The Company has not experienced any losses from maintaining cash balances in excess of such limits. Short-term Investments Short-term investments represent investments in certificate of deposits with remaining maturities of one year or less, but greater than three months, at the time of acquisition and are stated at carrying value, which approximates estimated fair value. Interest on short-term investments is recorded and is presented as a component of interest expense in the accompanying consolidated statements of operations and comprehensive income (loss). Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are stated at the amounts due from customers for products or services provided. The Company evaluates the collectability of its accounts receivable based on management's estimate for expected credit losses for outstanding accounts receivables. The Company determines expected credit losses based upon a number of factors, including historical experience, the likelihood of payment from its customers, and any other known specific factors associated with its customers. The Company maintains an allowance for doubtful accounts for estimated losses inherent in its accounts receivable and reassess the adequacy of the allowance each reporting period. Account balances are charged-off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. As of December 31, 2024 and 2023, the allowance for doubtful accounts was insignificant. Inventories Inventories are stated at the lower of cost using the the weighted-average cost method or net realizable value. The Company evaluates inventories periodically during each reporting period for obsolete, excess, or slow-moving products and will record any adjustment, if necessary, to report these items at an estimated net realizable value. As of December 31, 2024 and 2023, the reserve for inventory obsolescence was insignificant. Property, Plant and Equipment, Net Property, plant and equipment acquired in business combinations are recorded at fair value at the date of acquisition. All other property, plant and equipment are stated at cost less accumulated depreciation. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the consolidated balance sheets and the resulting gain or loss is reflected in the consolidated statements of operations and comprehensive income (loss) in the period realized. Costs of maintenance and repairs are charged to expense as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows: Years Buildings 30–40 years Furniture and fixtures 1–8 Years Machinery and equipment 1–26 Years Vehicles 1–8 Years Leasehold improvements Shorter of remaining lease term or estimated useful life Business Combinations The Company accounts for its business combinations using the acquisition accounting method, which requires it to determine the fair value of identifiable assets acquired and liabilities assumed, including any contingent consideration, and record any residual purchase price as goodwill in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations. The Company records assets acquired and liabilities assumed at their respective fair value at the date of acquisition. Management uses its best estimates and assumptions to value assets acquired and liabilities assumed at the acquisition date. Such estimates are inherently uncertain and may be subject to refinement. If the initial accounting for the business combination has not been completed by the end of the reporting period in which the business combination occurs, provisional amounts are reported to present information about facts and circumstances that existed as of the acquisition date. During the measurement period of up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill, to the extent such information was not available to the Company at the acquisition date to determine such amounts. Accounting for business combinations requires the Company to make significant estimates and assumptions at the acquisition date, including estimates of the fair value of acquired inventory, property and equipment, identifiable intangible assets, contractual obligations assumed, preacquisition contingencies, where applicable, and equity issued. Significant assumptions relevant to the determination of the fair value of the assets acquired and liabilities assumed include, but are not limited to, future expected cash flows, discount rates, royalty rates, and other assumptions. The approach to valuing the initial contingent consideration associated with the purchase price also uses similar unobservable factors such as projected revenues and expenses over the term of the contingent earn-out period, discounted for the period over which the initial contingent consideration is measured, and relevant volatility rates. Based upon these assumptions, the initial contingent consideration is then valued using a Monte Carlo simulation. All acquisition-related costs, other than the costs to issue debt or equity securities, are accounted for as expenses in the period in which they are incurred. Changes in the fair value of contingent consideration arrangements that are not measurement period adjustments are recognized in earnings. Goodwill Goodwill is deemed to have an indefinite life and is assessed for impairment annually at the reporting unit level or more frequently when events or circumstances occur that indicate that it is more likely than not that the fair value of a reporting unit or an intangible asset is less than its carrying value. The Company conducts an annual impairment test on October 1st each year. Depending on the facts and circumstances, the impairment test for goodwill can be performed using either a qualitative or quantitative approach. The qualitative approach consists of a weighting of several qualitative factors, including, but not limited to, macroeconomic conditions (including changes in interest rates and discount rates), industry and market considerations, the recent and projected financial performance of the reporting unit, changes in the Company's enterprise market value and other relevant factors to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount, including goodwill. This assessment can require significant judgments, including the estimation of future cash flows and an assessment of market and industry dependent risks. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, a quantitative goodwill impairment test is not necessary. If the assessment of all relevant qualitative factors indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company will perform a quantitative goodwill impairment test. The Company has the unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing a quantitative goodwill impairment assessment. The Company performed a qualitative analysis on October 1, 2024, the date of the Company’s annual impairment assessment, and concluded that it was more likely than not that the fair value of the Fire Safety and Specialty Products reporting units are greater than the respective carrying amounts. There was no impairment of goodwill during the years ended December 31, 2024, 2023, or 2022 . Intangible Assets Intangible assets with finite useful lives are amortized on a straight-line basis over their estimated useful lives, which vary depending on the type of intangible assets. Costs to maintain and extend intangible assets are expensed as incurred. In determining the estimated useful lives of definite-lived intangible assets, the Company considers the nature, competitive position, life cycle position and historical and expected future operating cash flows of each acquired assets, as well as its commitment to support these assets through continued investment and legal infringement protection. Impairment of Long-Lived Assets Long-lived assets include acquired property, plant, and equipment and intangible assets subject to amortization. The Company evaluates the recoverability of long-lived assets for possible impairment when events or changes in circumstances indicate that the carrying amount of such assets may not be fully recoverable. Such events and changes may include significant changes in performance relative to expected operating results, significant changes in asset use, significant negative industry or economic trends, and changes in the Company’s business strategy. The Company determines the recoverability of such assets by comparing an asset’s respective carrying value to estimates of the sum of the undiscounted future cash flows expected to result from its asset group. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair val ue. During the year ended December 31, 2023, the Company determined there was an impairment in a long-lived technology asset. See Note 4, “Goodwill and Other Intangible Assets” for additional information related to the impairment of long-lived assets. There were no impairments of long-lived assets during the years ended December 31, 2024 or 2022. Revenue Recognition The Company follows the guidance in ASC Topic 606, Revenue from Contracts with Customers , which requires a company to recognize revenue when the company transfers control of promised goods and services to the customer. Revenue is recognized in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. A company also is required to disclose sufficient quantitative and qualitative information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The Company derives its revenue from contracts with customers, which comprise of following principal activities as described: • Full-service air base fire retardant includes sales from the supply and service of fire retardant to designated air tanker bases. The Company provides fire retardant product, the related equipment, and service personnel who operate the related equipment at the designated air tanker bases for the period specified in the contract with respect to each designated air tanker base. Product revenues are recognized at the point in time when product is shipped and control is transferred to the customer, typically when the product is consumed by the customer. The component of service revenue is recognized ratably over time as the customer simultaneously receives and consumes the services. The Company has entered into full-service contracts with the U.S. Forest Service (“USFS”) and the state of California. These contracts are between Perimeter Solutions and the USFS and/or the state of California for supply and service of long-term fire retardant to the designated air tanker bases of certain Government agencies. The revenue derived from these contracts is comprised of multiple performance obligations, namely product sales, providing operations and maintenance personnel services, leasing of specified equipment, and expedited delivery capabilities. The performance obligation for product sales is satisfied at a point in time, while for services and leases it is a “stand-ready obligation” and the revenue is recognized straight-line over the service period. Control of a product is deemed to be transferred to the customer upon shipment or delivery. • Fire retardant, suppressant, and related equipment includes domestic and international sales of fire retardant and fire suppressant products. Product revenues are recognized at the point in time when control of the product is transferred to the customer which is upon shipment or delivery of the product to the customer, depending on the underlying contract terms. • Specialty Products includes domestic and international sales of specialty chemical and other products by the Company entities in the U.S. and Germany. Product revenues are recognized at the point in time when control of the product is transferred to the customer which is upon shipment or delivery of the product to the customer, depending on the underlying contract terms. The Company uses the policy election to account for the shipping and handling activities as activities to fulfill the Company’s promise to transfer goods to the customer, rather than as a performance obligation. Accordingly, the costs of the shipping and handling activities are accrued for at the time of shipment. The transaction price of a contract, or the amount the Company expects to receive upon satisfaction of all performance obligations, is determined by reference to the contract’s terms and includes adjustments, if applicable, for any variable consideration, such as sales incentives, wherever these adjustments are material. For full service contracts the transaction price is variable and is based upon gallons of product consumed by the customer during the service period i.e., mobilization period, which typically lasts during May through September. The Company includes the estimated amount of variable consideration in transaction price that it expects to receive to the extent it is probable that a significant revenue reversal will not occur. Sales and other taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, which are collected by the Company from a customer, are excluded from revenue. Payment terms vary by contract and sales to customers are deemed collectible at the time of sale based on customer history, prior credit checks, and controls around customer credit limits. The Company does provide for the right to return; however, most of the product is used at the point of purchase and returns are minimal. Therefore, there is no estimated obligation for returns. Standard terms of delivery are generally included in the Company's contracts of sale, order confirmation documents and invoices. Cost to Obtain Contract Incremental costs of obtaining a contract include only those costs that are directly related to the acquisition of contracts, including sales commissions, and that would not have been incurred if the contract had not been obtained. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if it is expected that the economic benefit and amortization period will be longer than one year. Costs to obtain contracts were not material in the periods presented. Deferred Revenue Deferred revenue represents billings under non-cancelable contracts before the related product or service is transferred to the customer. The portion of deferred revenue that is anticipated to be recognized as revenue during the succeeding twelve-month period is recorded as deferred revenue and the remaining portion is recorded as deferred revenue, non-current. Certain contracts entered by the Company have duration of one year or more. Any billings made to the customer during the financial year for which the related product or service is yet to be delivered on the cutoff date, i.e., December 31, is recognized as deferred revenue. Deferred revenue was $1.8 million and zero as of December 31, 2024 and 2023, respectively . For full-service fire-retardant contracts, the Company identifies the fire-retardant product and the services as separate units of account. Substantially all performance obligations are satisfied by the end of the annual financial reporting period and the allocation of transaction price to each performance obligation does not have an impact on the recognition and measurement of revenues for the annual reporting period. There were no contract assets, contract obligations other than deferred revenue, or material rights as of December 31, 2024 and 2023. Deferred Financing Fees As of December 31, 2024 and 2023 , unamortized debt issue costs of $7.2 million and $8.5 million, respectively, for the Company's Senior Notes were carried as a contra liability and are amortized over the term of the related debt using the effective interest method. As of December 31, 2024 and 2023, unamortized deferred financing costs of $0.8 million and $1.3 million, respectively, for the Company’s five-year revolving credit facility (the “Revolving Credit Facility”) were carried as a long-term asset and were amortized on a straight-line basis into interest expense over the term of the Revolving Credit Facility. Amortization of deferred financing fees was $1.3 million, $1.2 million and $1.2 million for Senior Notes and $0.5 million, $0.5 million and $0.5 million for the Revolving Credit Facility during the years ended December 31, 2024, 2023 and 2022, respectively, and is presented as a component of interest expense in the consolidated statements of operations and comprehensive income (loss). Income Taxes Income taxes are accounted for under the asset-and-liability method. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities, as well as loss and tax credit carryforwards and their respective tax bases measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income in assessing the need for a valuation allowance. Deferred tax assets and deferred tax liabilities are presented as non-current in a classified balance sheet. The Company’s tax positions are subject to income tax audits by multiple tax jurisdictions throughout the world. The Company recognizes the tax benefit of an uncertain tax position only if it is more likely than not the position will be sustainable upon examination by the taxing authority, including resolution of any related appeals or litigation processes. This evaluation is based on all available evidence and assumes that the tax authorities have full knowledge of all relevant information concerning the tax position. The tax benefit recognized is measured as the largest amount of benefit which is more likely than not (greater than 50% likely) to be realized upon ultimate settlement with the taxing authority. The Company recognizes interest accrued and penalties related to unrecognized tax benefits in income tax expense (benefit). The Company makes adjustments to these reserves in accordance with the income tax guidance when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate. To the extent that the final tax outcome of these matters is different from the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on the Company’s financial condition and operating results. Leases The Company leases certain manufacturing facilities, real estate, vehicles, and field equipment. Such leases, some of which are noncancellable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company’s lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate. The Company does not currently sublease any of its ROU assets. The Company elects to apply the short-term lease exception for lease arrangements with a lease term of 12 months or less at commencement. The Company has lease agreements with lease and non-lease components, which are generally accounted for as a single lease component. Lease terms used to compute the present value of lease payments do not include any option to extend, renew, or terminate the lease that the Company is not reasonably certain to exercise upon the lease inception. Accordingly, lease ROU assets and liabilities do not include leases with an initial lease term of 12 months or less. The Company determines if an arrangement is an operating lease or a finance lease at inception. For both types of leases ROU assets and lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expenses are recognized on a straight-line basis over the lease term. Variable lease payments, which cannot be determined at the lease commencement date, are not included in ROU assets or lease liabilities and are expensed as incurred. Finance lease ROU assets are amortized over the estimated useful life of the underlying asset with expenses presented in cost of goods sold in the accompanying consolidated statements of operations and comprehensive income (loss). Finance lease liabilities are subsequently remeasured by increasing the liability to reflect interest accrued during the period and decreasing the liability to reflect payments made during the period. Interest expense incurred on finance leases is included in interest expense in the accompanying consolidated statements of operations and comprehensive income (loss). Cash paid for operating leases and interest paid for finance leases are included in the consolidated statement of cash flows as operating activities and cash paid for finance lease principal is included in the financing activities section of the consolidated statements of cash flows. As most leases do not have readily determinable implicit rates, the Company estimated the incremental borrowing rates for its future lease payments based on prevailing financial market conditions at the later of date of adoption or lease commencement, credit analysis of comparable companies and management judgments to determine the present values of its lease payments. The Company also applied the portfolio approach to account for leases with similar terms. Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. When a single amount cannot be reasonably estimated but the cost can be estimated within a range, the Company accrues the minimum amount. Legal costs incurred in connection with loss contingencies are expensed as incurred. Foreign Currencies Prior to the Redomiciliation Transaction, the functional and reporting currencies for all Luxembourg entities were in U.S. dollars. The functional currency for the Company’s remaining non-U.S. subsidiaries is the local currency. The assets and liabilities of foreign subsidiaries are translated into U.S. dollars using the exchange rate in effect as of the balance sheet date except for non-monetary assets and liabilities, which are measured at historical exchange rates and revenues and expenses are translated at the average exchange rates for each respective reporting period. Adjustments resulting from translating local currency financial statements into U.S. dollars are reflected in accumulated other comprehensive loss in shareholders’ equity. The Company does not recognize deferred taxes on translation adjustments from its investments in foreign subsidiaries that are essentially permanent in duration. Transactions denominated in currencies other than the functional currency are remeasured based on the exchange rates at the time of the transaction. Foreign currency gains and losses arising primarily from changes in exchange rates on foreign currency denominated intercompany loans and other intercompany transactions and balances between foreign locations are recorded in the consolidated statements of operations and comprehensive income (loss). Realized and unrealized (losses) gains resulting from transactions conducted in foreign currencies for the years ended December 31, 2024, 2023 and 2022 were $(2.6) million, $1.4 million and $(4.0) million, respectively. Share-Based Compensation Performance stock options The performance-based non-qualified stock options ("PBNQSO") granted to employees and non-employees are subject to performance conditions such that the number of awards that ultimately vest depends on the calculation of annual operational performance per diluted share (“AOP”) during the performance period compared to targets established at the award date. Because the terms of the PBNQSO granted through December 31, 2022 (“Prior Option Grants”) provided discretion to the compensation committee to make certain adjustments to the performance calculation, the service inception date of these awards preceded the grant date. Accordingly, the Company recognized compensation expense beginning on the service inception date and remeasured the fair value of the awards until a grant date was established. The estimate of the awards’ fair values will be fixed in the period in which the grant date occurs, and cumulative compensation expense will be adjusted based on the fair values calculated using the Black-Scholes option-pricing model at the grant date. The fair value for PBNQSO for which a grant date has not been established was estimated on the last date of the reporting period using the Black-Scholes option-pricing model. On February 14, 2023 and to be effective prospectively, the compensation committee approved the elimination of “Unusual or Nonrecurring Transactions or Events” provision in the PBNQSO agreement whereby it could make certain adjustments to operational performance criteria “for unusual or nonrecurring transactions or events affecting the Company or the financial statements of the Company.” This provision had precluded the establishment of a grant date on the date when PBNQSO were awarded in accordance with the technical requirements under ASC Topic 718, “Compensation—Stock Compensation”. Further, on May 8, 2023 (“Options Modification Date”), to better account for seasonal fluctuations of the business, and to better align stock option performance with shareholder return, the compensation committee approved modification of certain terms in PBNQSO agreement for all PBNQSO granted through May 8, 2023. One modification eliminated the “Unusual or Nonrecurring Transactions or Events” provision. As of May 8, 2023, it was determined that a mutual understanding of the key terms and conditions of the PBNQSO has been ascertained and the grant date was therefore established for the Prior Option Grants. For stock options granted from February 14, 2023 through May 7, 2023 (“Pre Modification 2023 Option Grants”), t he Company recognized compensation costs related to PBNQSO granted to employees and non-employees based on the estimated fair value of the awards on the date of grant using the Black-Scholes option-pricing model. On the Options Modification Date, the Company performed a fair value remeasurement under the original terms of Prior Option Grants and Pre Modification Option Grants using the Hull-White model and determined there was no incremental share-based compensation expense. For Prior Option Grants and the stock options granted on or after May 8, 2023 (“Post Modification 2023 Option Grants”) t he Company recognizes compensation costs related to PBNQSO granted to employees and non-employees based on the estimated fair value of the awards on the date of grant using the Hull-White model as this model considers the future movement in the price of the Company’s shares of Common Stock and option holders’ behavior with respect to option exercises. The assumptions used in the Black-Scholes option-pricing model are as follows: • Exercise price. The Company's ordinary share’s fair market value on the date of grant. • Fair Market Value of Ordinary Shares. Subsequent to the Business Combination, the period end fair market value was the quoted market price of the Company's Ordinary Shares. For Pre Modification 2023 Option Grants, the fair market value was the quoted market price of the Company's Ordinary Shares on the date of grant. • Expected term. The expected term of stock options represents the period that the stock options are expected to remain outstanding and was based on vesting terms, exercise term and contractual lives of the options. The expected term is based on the simplified method and is estimated as the average of the weighted average vesting term and the time to expiration as of the period end date. The simplified method was used due to the lack of historical exercise information. • Expected volatility. As the Company did not have sufficient historical stock price information to meet the expected life of the stock option grants, it used a blended volatility, based on Company’s short trading history and on the trading history from the common stock of a set of comparable publicly listed companies. • Risk-free interest rate. The risk-free interest rate was based on the U.S. Treasury yield with a maturity equal to the expected term of the stock options in effect at the time of grant. • Dividend yield. The expected dividend wa |
