Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	NOTE 1 – ORGANIZATION AND BASIS OF PRESENTATION Nature of Business Bridger Aerospace Group Holdings, Inc. and its subsidiaries (“Bridger”, “the Company,” “we,” “us” or “our”) provide aerial wildfire management, relief and suppression and delivery of firefighting services using next generation technology and sustainable and environmentally safe firefighting methods. The Company was formed on November 20, 2018 and registered in the State of Delaware. The legal name of the Company was officially changed from ElementCompany Operations, LLC to Bridger Aerospace Group Holdings, LLC through an amendment with the State of Delaware, effective January 1, 2020. As of December 31, 2023, the Company owns fifteen aircraft, including six Viking CL-415EAFs (“Super Scoopers”), four Twin Commander surveillance platforms (“Twin Commanders”), four Daher Kodiaks 100s (“Daher Kodiaks”), and one Pilatus PC-12 (“Pilatus”). Liquidity and Going Concern In accordance with Accounting Standards Codification (“ASC”) Topic 205-40, Going Concern , the Company has evaluated whether there are certain conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within 12 months after the date that these consolidated financial statements are issued. This evaluation includes considerations related to the covenants contained in the Company’s loan agreements as well as the Company’s liquidity position overall. As detailed in Note 16 - Long-Term Debt , the Company’s municipal bond issuances by Legacy Bridger that closed in July and August 2022 (the “Series 2022 Bonds”) contain customary covenants and restrictions, including financial and non-financial covenants. The financial covenants require the Company to maintain a debt service coverage ratio (“DSCR”) that exceeds 1.25x commencing with the fiscal quarter ending December 31, 2023, operate in such a manner to produce gross revenues so as to be at all relevant times in compliance with the DSCR covenant and to maintain liquidity of $8.0 million in the form of unrestricted cash or investments (excluding margin accounts and retirement accounts) at all times. Failure to comply with these covenants could result in an event of default, subject to certain exceptions. For the year ended December 31, 2023, the Company had an operating loss of $57.5 million, net loss of $77.4 million and cash flow used in operating activities of $26.8 million. In addition, as of December 31, 2023, the Company had unrestricted cash or investments of $24.0 million. The Company is not in compliance with the DSCR covenant as of December 31, 2023 and management anticipates the Company to continue to not be in compliance with the DSCR covenant at future quarterly measurement periods in the next 12 months, primarily attributable to the seasonal nature of our business and a less intense 2023 wildfire season. Although the Company is in compliance with the $8.0 million minimum liquidity requirement as of December 31, 2023, based on projected cash use, management anticipates that without additional cash funding the Company will not have sufficient cash on hand to fund operations, including $18.4 million of required interest payments associated with the Series 2022 Bonds, or to comply with the minimum liquidity covenant within the next 12 months, or until the Company begins to collect cash from its seasonal firefighting operations in 2024. The Series 2022 Bonds agreements provide that, with regard to covenant violations, other than non-payment of principal or interest, no event of default shall be deemed to have occurred so long as a reasonable course of action to remedy a violation commences within 30 days of written notice of non-compliance from the trustee and management diligently prosecutes the remediation plan to completion. Management consulted with bond counsel on the impact of covenant violations and proactively developed a cost reduction plan, and began implementing the plan in November 2023, to help remedy the anticipated covenant breaches in 2024. However, this plan is in progress and there is no assurance that management will be able diligently prosecute the remediation plan to completion. In addition to the cost reduction measures implemented in November 2023, the Company plans to seek additional cash funding through a number of potential avenues, including additional sales of our common stock through our at-the-market offering, described in further detail in Note 24 - Subsequent Events, and issuing additional shares of common stock pursuant to our shelf registration statement. These additional sources of working capital are not currently assured, and consequently do not sufficiently mitigate the risks and uncertainties disclosed above. Our ability to raise additional funds will depend on, among other factors, financial, economic and market conditions, many of which are outside of our control and there can be no assurance that we will be able to obtain additional funding on satisfactory terms or at all. Current and anticipated noncompliance with financial covenants and uncertainty regarding the Company’s ability to diligently prosecute the cost reduction plan and to raise additional cash funding for operations, including required interest payments associated with the Series 2022 Bonds, raise substantial doubt about the Company’s ability to continue as a going concern within 12 months following the issuance date of the consolidated financial statements as of and for the period ended December 31, 2023. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that might be necessary should the Company be unable to continue as a going concern. Basis of Presentation The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The consolidated financial statements include the financial statements of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. Reverse Recapitalization On January 24, 2023, (the “Closing Date”), Jack Creek Investment Corp (“JCIC”) completed the reverse recapitalization (the “Closing” and the “Reverse Recapitalization”) with the Company’s predecessor, Bridger Aerospace Group Holdings, LLC and its subsidiaries (collectively, “Legacy Bridger”), which operated the majority of the historical business and was identified as the acquirer and predecessor upon the consummation of the transactions contemplated by the agreement and plan of merger (the “Transaction Agreements”) entered into on August 3, 2022. On the Closing Date, pursuant to the Transaction Agreements, JCIC and Legacy Bridger became wholly owned subsidiaries of a new public entity that was renamed Bridger Aerospace Group Holdings, Inc., and JCIC shareholders and Legacy Bridger equity holders converted their equity ownership in JCIC and Legacy Bridger, respectively, into equity ownership in Bridger. Upon the consummation of the Reverse Recapitalization, Bridger issued Common Stock to the Legacy Bridger equity holders and Series A Preferred Stock (as defined below) as summarized below: • the surrender and exchange of all 606,061 Legacy Bridger incentive units (“Incentive Units”) into 583,308 shares of Bridger’s common stock, par value $0.0001, (“Common Stock”) at a deemed value of $10.00 per share as adjusted by the per share Common Stock consideration of approximately 0.96246 (the “Exchange Ratio”), rounded down to the nearest share for each holder; • the direct or indirect surrender and exchange of the remaining 40,000,000 issued and outstanding shares of Legacy Bridger common shares (excluding Incentive Units) into 38,498,436 shares of Common Stock at a deemed value of $10.00 per share as adjusted by the Exchange Ratio, rounded down to the nearest share for each holder; and • the surrender and exchange of all 315,789.473684 issued and outstanding Series C preferred shares of Legacy Bridger (the “Legacy Bridger Series C Preferred Shares”), which were surrendered and exchanged on a one-to-one basis in connection with the Reverse Recapitalization into 315,789.473684 shares of preferred stock of Bridger that have the rights, powers, designations, preferences, and qualifications, limitations and restrictions set forth in Section 4.5 of the Amended and Restated Certificate of Incorporation (the “Series A Preferred Stock”). The Series A Preferred Stock are convertible at the election of the holders into shares of Common Stock, without the payment of additional consideration by the holders into such number of shares of Common Stock as determined by dividing the original issue price, plus accrued interest by a conversion price equal to $11.00 at the time of conversion. Other related events occurred in connection with the Reverse Recapitalization, are summarized below: • the filing and effectiveness of the Amended and Restated Certificate of Incorporation of Bridger and the effectiveness of the Amended and Restated Bylaws of Bridger, each of which occurred immediately prior to the Closing; • the adoption and assumption of the 2023 Omnibus Incentive Plan and any grants or awards issued thereunder and adoption of the 2023 Employee Stock Purchase Plan upon the Closing to grant equity awards to Bridger employees; and • during the period from the Closing until five years following the Closing, JCIC subjected 20% of JCIC’s issued and outstanding common stock (“Sponsor Earnout Shares”), comprised of two separate tranches of 50% of the Sponsor Earnout Shares per tranche, to potential forfeiture to Bridger for no consideration until the occurrence (or deemed occurrence) of certain triggering events. Immediately after giving effect to the Transaction Agreements, the following were outstanding: • 43,769,290 shares of Common Stock; • 315,789.473684 shares of Bridger Series A Preferred Stock; • 9,400,000 private placement warrants (“Private Placement Warrants”) to purchase shares of Common Stock at an exercise price of $11.50 per share; • 17,250,000 public warrants (“Public Warrants”) to purchase shares of Common Stock at an exercise price of $11.50 per share; and • 6,581,497 restricted stock units issued to the executives and senior management of the Company. In connection with the Reverse Recapitalization, the Company paid transaction costs of $10.3 million as of the Closing. The transactions contemplated by the Transaction Agreements were accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, JCIC was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of Bridger represent a continuation of the financial statements of Legacy Bridger with the Reverse Recapitalization treated as the equivalent of Legacy Bridger issuing stock for the net assets of JCIC, accompanied by a recapitalization. The net assets of JCIC will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Reverse Recapitalization will be those of Legacy Bridger in future reports of Bridger. Legacy Bridger has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • Legacy Bridger equity holders have a relative majority of the voting power of Bridger; • Bridger’s board of directors (the “Board”) has eleven members, and representatives or designees of the Legacy Bridger equity holders comprise the majority of the members of the Board; • Legacy Bridger’s senior management comprise the senior management roles and are responsible for the day-to-day operations of Bridger; • Bridger assumed Legacy Bridger’s name of business; • The strategy and operations of Bridger continue Legacy Bridger’s former strategy and operations; and • The Reverse Recapitalization created an operating public company, with management continuing to use Legacy Bridger operations to grow the business. The Sponsor Earnout Shares are determined to be equity classified instruments of Bridger and the Public Warrants and Private Placement Warrants are determined to remain liability classified instruments upon the Closing. In accordance with guidance applicable to these circumstances, the equity structure has been recast in all comparative periods up to the Closing to reflect the number of shares of Common Stock issued to Legacy Bridger’s stockholders in connection with the Reverse Recapitalization. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Bridger’s common stock prior to the Reverse Recapitalization have been retroactively recast as shares of Common Stock using the Exchange Ratio.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The Company consolidates those entities in which it, through the existing owners, has control over significant operating, financial or investing decisions of the entity. All significant intercompany balances and transactions have been eliminated in consolidation. Variable Interest Entities The Company follows ASC 810-10-15 guidance with respect to accounting for variable interest entities (“VIE”). These entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support from other parties or whose equity investors lack any of the characteristics of a controlling financial interest. A variable interest is an investment or other interest that will absorb portions of a VIE’s expected losses or receive portions of its expected returns and are contractual, ownership or pecuniary in nature and that change with changes in the fair value of the entity’s net assets. A reporting entity is the primary beneficiary of a VIE and must consolidate it when that party has a variable interest, or combination of variable interests, that provide it with a controlling financial interest. A party is deemed to have a controlling financial interest if it meets both of the power and loss/benefits criteria. The power criterion is the ability to direct the activities of the VIE that most significantly impact its economic performance. The losses/benefits criterion is the obligation to absorb losses from, or right to receive benefits from, the VIE that could potentially be significant to the VIE. The VIE model requires an ongoing reconsideration of whether a reporting entity is the primary beneficiary of a VIE due to changes in the facts and circumstances. Northern Fire Management Services, LLC (“NFMS, LLC”): The Company assisted in designing and organizing NFMS, LLC with a business purpose of employing Canadian aviation professionals to provide services to the Company. A master services agreement exists between NFMS, LLC and the Company, Bridger Air Tanker, LLC, a wholly owned subsidiary of the Company, to transfer all annual expenses incurred to the Company in exchange for the Canadian employees to support the Company’s water scooper aircraft. NFMS, LLC is 50% owned by a Canadian citizen, and 50% owned by Bridger Aerospace Group, LLC (“BAG, LLC”). NFMS, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s responsibility for all decisions related to NFMS, LLC’s expenditures. Accordingly, NFMS, LLC has been consolidated by the Company for the years ended December 31, 2023 and 2022 and all intercompany expenses associated with NFMS, LLC and its service agreement have been eliminated in consolidation. For the years ended December 31, 2023 and 2022, NFMS, LLC’s assets and liabilities were immaterial to the Company’s financial statements. Mountain Air, LLC (“MA, LLC”): As of November 7, 2022, MA, LLC is a wholly-owned subsidiary of Bridger. Prior to MA, LLC becoming a wholly-owned subsidiary of the Company, MA, LLC was owned 50% by Timothy Sheehy, the Chief Executive Officer and a director of Bridger, and 50% by an entity affiliated with Matthew Sheehy, a director of Bridger. MA, LLC is a Federal Aviation Administration (“FAA”) part 135 certificate holder and is designed to hold aerial firefighting contracts. Bridger Aviation Services, LLC (“Bridger Aviation”), a wholly-owned subsidiary of Bridger, was a party to a certain Management Services Agreement (the “Aviation Agreement”), dated April 13, 2018, with MA, LLC. Pursuant to the Aviation Agreement, Bridger Aviation leased certain aircraft to MA, LLC. MA, LLC operated the aircraft and paid Bridger Aviation a fee equal to 99% of all revenue it received from the use and deployment of Bridger Aviation’s aircraft. MA, LLC was obligated to operate and maintain the aircraft in accordance with applicable FAA standards. MA, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s substantial control. Accordingly, the Company consolidated MA, LLC for the periods prior to November 7, 2022 and all intercompany expenses associated with MA, LLC and its Aviation Agreement were eliminated in consolidation. On November 17, 2023, we entered into a series of agreements designed to facilitate the purchase and return to service of four Canadair CL-215T Amphibious Aircraft (the “Spanish Scoopers”) originally awarded to our wholly-owned subsidiary, Bridger Aerospace Europe, S.L.U. (“BAE”), in September 2023 via a public tender process from the Government of Spain for €40.3 million. Under the terms of the agreements, we agreed to sell the entire outstanding equity interest in BAE to MAB and purchase $4.0 million of non-voting Class B units of MAB. We also entered into a services agreement with MAB whereby we will manage the return to service upgrades of the Spanish Scoopers through our wholly-owned Spanish subsidiary, Albacete Aero, S.L., while they are owned and funded by MAB. The service agreement also provides that we have the right, but not the obligation, to acquire each Spanish Scooper as it is ready to be contracted and returned to service. The Company assessed both MAB and BAE for variable interest entity accounting under ASC 810-10-15 and determined that MAB is a voting interest entity and BAE is a variable interest entity. However, neither entity is consolidated in the consolidated financial statements as the Company does not have a controlling financial interest in MAB and the Company is not the primary beneficiary of BAE. Accordingly, neither of these entities have been consolidated in the consolidated financial statements of the Company for the year ended December 31, 2023. Refer to “Note 17 – Commitments and Contingencies” included in this Annual Report on Form 10-K for additional details. Seasonality The Company’s business is generally seasonal, with a significant portion of total revenue occurring during the second and third quarters of the fiscal year due to the North American fire season. However, the weather dependency and seasonal fluctuation in the need to fight wildfires based upon location and the varying intensity of the fire season may lead our operating results to fluctuate significantly from quarter to quarter and year to year. Use of Estimates The preparation of financial statements in conformity with GAAP, requires management to make assumptions and estimates that affect the reported amounts of assets and liabilities, disclosure of gain or loss contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from their estimates and such differences could be material to the consolidated financial statements. Significant items subject to such estimates and assumptions include: (a) excess and aging aircraft support parts reserves, (b) allowance for doubtful accounts, (c) useful lives of property, plant and equipment, net, (d) allocation of the purchase price to the fair value of assets acquired and liabilities assumed, (e) impairment of long-lived assets, goodwill and other intangible assets, (f) disclosure of fair value of financial instruments, (g) variable interest entities, (h) accounting for Series A Preferred Stock and Legacy Bridger Series C Preferred Shares, (i) revenue recognition, (j) estimates and assumptions made in determining the carrying values of goodwill, other intangible assets, and contingent consideration and (k) Public Warrants and Private Placement Warrants. Cash and Cash Equivalents Cash and cash equivalents consist of cash and all highly liquid, readily convertible investments with a maturity of three months or less. Cash equivalents are placed primarily in time deposits and money market funds due in three months or less. The Company’s subsidiaries generally maintain cash account balances sufficient to meet their short-term working capital requirements and periodically remit funds to the parent company to pay intercompany lease, maintenance and other charges. Substantially all of the Company’s cash is concentrated in a few financial institutions. At times, deposits in these institutions exceed the federally insured limits. Restricted Cash Restricted cash includes cash and cash equivalents that are not readily available for use in the Company’s operating activities. The Company had $14.0 million and $12.3 million of restricted cash as of December 31, 2023 and 2022, respectively. These funds are held in a demand deposit account or highly rated money market fund. The Company had $14.0 million and $9.3 million in restricted cash related to the Series 2022 Bonds and zero and $3.0 million of restricted cash held in escrow as of December 31, 2023 and 2022, respectively. Investments in Marketable Securities Investments in debt securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income. Gains and losses are recognized when realized. Unrealized losses are evaluated for impairment to determine if the impairment is credit related. An other-than-temporary credit impairment would be recognized as an adjustment to income. Gains and losses are determined using the first-in first-out method. Investments in marketable securities are classified as current assets with short-term maturities of less than one year. Accounts and Note Receivable Accounts receivable consist of amounts due from our customers. The Company maintains an allowance for doubtful accounts equal to the estimated losses expected to be incurred based upon a review of the outstanding accounts receivable, historical collection information and existing economic conditions. For the years ended December 31, 2023 and 2022, the Company did not record any bad debt expense as accounts receivable have historically been collected in accordance with the policy and there is no history of write-offs. Notes receivable consists of a promissory note to pay a specific sum, with interest, within a defined period. Each reporting period, the Company evaluates the collectability of the outstanding note receivable balance. If the promissory note is deemed uncollectible, the Company will record the value of the note and the accrued interest as bad debt expense. For the years ended December 31, 2023 and 2022, the Company did not record any bad debt expense based on the assessment of the receivable. Aircraft Support Parts Aircraft support parts consist of repairables and expendables that are used for servicing aircraft and support parts for universal application amongst the aviation fleet. Aircraft support parts are tracked by serial number and capitalized at cost in the Consolidated Balance Sheets and expensed in the Consolidated Statements of Operations when used in operations. Property, Plant and Equipment, net Property, plant and equipment are recorded at cost when acquired. Except for aircraft, engines and rotable parts, depreciation is computed on the straight-line basis over the estimated useful life of property, plant and equipment and is recorded in Cost of revenues and Selling, general and administrative expense in the Consolidated Statements of Operations. Depreciation for aircraft, engines and rotable parts is recorded over the estimated useful life based on flight hours. The table below summarizes depreciable lives by asset category: Estimated Useful Life Aircraft, engines and rotable parts 1,500 – 6,000 flight hours Vehicles and equipment 3 – 5 years Buildings 40 years Aircraft undergo maintenance activities including routine repairs, inspections, part replacements and overhauls as required by regulatory authorities or manufacturer specifications. Costs of routine maintenance of aircraft are expensed as incurred as Cost of revenues in the Consolidated Statements of Operations. Costs that increase the value of the aircraft are capitalized as Property, plant and equipment, net in the Consolidated Balance Sheets and are depreciated over the asset’s useful life. Upon retirement or sale, the property, plant and equipment disposed of and the related accumulated depreciation are removed from the Consolidated Balance Sheets and any resulting gain or loss is recorded as Selling, general and administrative expense in the Consolidated Statements of Operations. Interest on long-term debt for the development or manufacturing of Company assets is capitalized to the asset until the asset enters production or use, and thereafter all interest is charged to expense as incurred. Business Combinations The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting in accordance with ASC 805, Business Combinations . Under the acquisition method of accounting, amounts paid for the acquisition are allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition inclusive of identifiable intangible assets. Acquisition consideration includes contingent consideration with payment terms based on the achievement of certain targets of the acquired business. The estimated fair value of identifiable assets and liabilities, including intangibles, are based on valuations that use information and assumptions available to management. The Company allocates any excess purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. Significant management judgments and assumptions are required in determining the fair value of assets acquired and liabilities assumed, particularly acquired intangible assets, including estimated useful lives. The valuation of purchased intangible assets is based upon estimates of the future performance and discounted cash flows of the acquired business. Each asset acquired or liability assumed is measured at estimated fair value from the perspective of a market participant. Contingent consideration represents an obligation of the acquirer to transfer additional assets or equity interests to the seller if future events occur or conditions are met, is recognized when probable and reasonably estimable. Contingent consideration recognized is included in the initial cost of the assets acquired and recorded in Accrued expenses and other current liabilities and Long-term accrued expenses and other noncurrent liabilities in the Consolidated Balance Sheets. Subsequent changes in the estimated fair value of contingent consideration are recognized as Selling, general and administrative expenses in the Consolidated Statements of Operations. Intangible Assets Intangible assets consist of finite-lived intangible assets acquired through the Company’s historical business combinations and software developed for internal-use. In accordance with ASC Topic 350-40, Software - Internal-Use Software , the Company capitalizes certain direct costs of developing internal-use software that are incurred in the application development stage, when developing or obtaining software for internal use. Once the internal use software is ready for its intended use, it is amortized on a straight-line basis over its useful life. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Acquired intangible assets are initially recorded at fair value and subsequently amortized over their useful lives using the straight-line method, which reflects the pattern of benefit, and assumes no residual value. Intangible assets with definite lives are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. The remaining estimated useful lives of definite-lived intangible assets are routinely reviewed and, if the estimate is revised, the remaining unamortized balance is amortized over the revised estimated useful life. Goodwill Goodwill represents the excess of purchase price over fair value of the net assets acquired in an acquisition. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Beginning in 2023, the Company assesses goodwill for impairment as of October 1 annually or more frequently upon an indicator of impairment. Prior to 2023, the Company assessed goodwill for impairment as of December 31 annually or more frequently upon an indicator of impairment. The change to an October 1 annual goodwill impairment assessment date was made to ensure the completion of the Company’s assessment prior to the end of its annual reporting period, thereby aligning impairment testing procedures with its year-end financial reporting. Goodwill is tested for impairment at the reporting unit level using a fair value approach. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, based on a review of qualitative factors, it is more likely than not that the fair value of a reporting unit is less than its carrying value the Company compares the fair value of a reporting unit with its carrying amount. The Company determines the fair value of a reporting unit by estimating the present value of expected future cash flows, discounted by the applicable discount rate. If the carrying value exceeds the fair value, the Company measures the amount of impairment loss, if any, by comparing the implied fair value of the reporting unit goodwill with its carrying amount. No impairment charges have been required. Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds its estimated undiscounted net cash flow, excluding interest, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds its fair value. Investments accounted for under the equity method are recorded based upon the amount of the Company’s investment and are adjusted each period for the Company’s share of the investee’s income or loss. Investments are reviewed periodically for changes in circumstances or the occurrence of events that suggest an other-than-temporary event where the investment may not be recoverable. Cost Method Investments The Company holds equity securities without a readily determinable fair value, which are only adjusted for observable price changes in orderly transactions for the same or similar equity securities or any impairment. As of December 31, 2023 and 2022, the Company had $5.0 million and $1.0 million of cost method investments included in Other noncurrent assets in the Consolidated Balance Sheets, respectively. Deferred Offering Costs Deferred offering costs primarily consist of capitalized legal, accounting and other third-party costs incurred that are directly related to the Reverse Recapitalization, which has been accounted for as a reverse recapitalization. These costs were recorded to Stockholders’ deficit as a reduction of Additional paid-in capital generated upon the completion of the Reverse Recapitalization. As of December 31, 2023, the Company recorded $18.0 million to Stockholders’ deficit in the Consolidated Balance Sheets. For the year ended December 31, 2023, the Company recorded $0.5 million to Selling, general and administrative expense in the Consolidated Statements of Operations. As of December 31, 2022, the Company recorded $5.8 million of deferred offering costs in the Consolidated Balance Sheets. Debt Issuance Costs Debt issuance costs consist of expenditures associated with obtaining debt financing, principally legal and bank commitment fees. Such costs are deferred and amortized over the term of the related credit arrangements using a method that approximates the effective interest method. Debt issuance costs are included in the Consolidated Balance Sheets as a direct deduction from the carrying amount of long-term debt and are included in Interest expense in the Consolidated Statements of Operations. The payment of debt issuance costs is recorded under financing activities in the Consolidated Statements of Cash Flows. Fair Value of Financial Instruments The Company follows guidance in ASC 820, Fair Value Measurement (“ASC 820”), where fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are determined within a framework that establishes a three-tier hierarchy which maximizes the use of observable market data and minimizes the use of unobservable inputs to establish a classification of fair value measurements for disclosure purposes. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the information available. ASC 820 classifies the inputs used to measure these fair values into the following hierarchy: Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs and quoted prices in active markets for similar assets and liabilities. Level 3 — Unobservable inputs and models that are supported by little or no market activity. In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety has been determined based on the lowest level of input that is significant to the fair value measurement. Revenue Recognition The Company charges daily and hourly rates depending upon the type of firefighting service rendered and under which contract the services are performed. These services are primarily split into flight revenue and standby revenue. Flight revenue is earned primarily at an hourly rate when the engines of the aircraft are started and stopped upon request of the customer, tracked via flight logs for Super Scoopers or a Hobbs meter for other aircraft. Standby revenue is earned primarily as a daily rate when aircraft are available for use at a fire base, awaiting request from the customer for flight deployment. The Company enters into short, medium and long-term contracts with customers, primarily with government agencies during the firefighting season, to deploy aerial fire management assets. Revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied and payment is typically due within 30 days of invoicing. Invoicing occurs as the services are rendered and includes the use of the aircraft, pilot and field maintenance personnel to support the contract. Contracts are based on either a Call-When-Needed (“CWN”) or Exclusive Use (“EU”) basis. Rates established are generally more competitive based on the security of the revenue from the contract (i.e., an EU versus only on an as-needed basis in CWN). These rates are delineated by the type of service, generally flight time or time available for deployment. Once an aircraft is deployed on a contract the fees are earned at these rates, the aircraft cannot be obligated to another customer. Contracts have no financing components and consideration is at pre-determined rates. No variable considerations are constrained within the contracts. The transaction prices are allocated on the service performed and tracked real-time by each operator in a duty log. On at least a monthly basis, the services performed and rates are validated by each customer. Acceptance by the customer is evidenced by their funded task order or accepted invoice. The Company has not incurred incremental costs for obtaining contracts with customers. In addition, the Company evaluates whether or not it should capitalize the costs of fulfilling a contract. Such costs would be capitalized when they are not within the scope of other standards and: (1) are directly related to a contract; (2) generate or enhance resources that will be used to satisfy performance obligations; and (3) are expected to be recovered. The Company has elected to use the practical expedient detailed in ASC 340-40, Other Assets and Deferred Costs-Contracts with Customers , to expense any costs to fulfill a contract as they are incurred when the amortization period would be one year or less. Contract assets are classified as a receivable when the reporting entity’s right to consideration is unconditional, which is when payment is due only upon the passage of time. As the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional, contracts do not typically give rise to contract assets. Contract liabilities are recorded when cash payments are received or due in advance of performance. Payment terms vary by customer and type of revenue contract. The Company generally expects that the period of time between payment and transfer of promised goods or services will be less than one year. In such instances, the Company has elected the practical expedient to not evaluate whether a significant financing component exists. As permitted under the practical expedient available under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, and (ii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. Other revenue consists of leasing revenues for facilities as well as external repair work performed on customer aircraft.

During the year ended December 31, 2022, the Company had one customer who individually accounted for 95% of total revenues and one customer who individually accounted for 62% of accounts receivable. Income Taxes For periods prior to the Business Combination, Bridger Aerospace Group Holdings, LLC is a partnership for federal income tax purposes. Consequently, federal income taxes are not payable or provided for by Legacy Bridger. Members are taxed individually on their pro rata ownership share of the Legacy Bridger’s earnings. Legacy Bridger’s net income or loss is allocated among the members in accordance with the Company’s operating agreement. Subsequent to the Business Combination, Bridger Aerospace Group Holdings, Inc. became the successor of Legacy Bridger as discussed in “ Note 1 – Organization and Basis of Presentation .” Bridger is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to net taxable income or loss and any related tax credits of the Company. Bridger is also subject to taxes in foreign jurisdictions in which it operates. The Company provides for income taxes and the related accounts under the asset and liability method. Income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. The Company is subject to income taxes predominantly in the U.S. These tax laws are often complex and may be subject to different interpretations. Deferred income taxes arise from temporary differences between the financial statement carrying amount and the tax basis of assets and liabilities and are measured using the enacted tax rates expected to be in effect during the year in which the basis difference reverses. In evaluating the ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence. If based upon all available positive and negative evidence, it is more likely than not that the deferred tax assets will not be realized, a valuation allowance is established. The valuation allowance may be reversed in a subsequent reporting period if Bridger determines that it is more likely than not that all or part of the deferred tax asset will become realizable. Segment Reporting Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The Company manages its operations as a single segment for purposes of assessing performance, making operating decisions and allocating resources. This one operating and reporting segment primarily focuses on aerial firefighting. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Depository Insurance Coverage of $250,000. During the years ended December 31, 2023 and 2022, the Company did not experience losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Hedging Transactions and Derivative Financial Instruments The Company is directly and indirectly affected by changes in certain market conditions. These changes in market conditions may adversely impact the Company’s financial performance and are referred to as “market risks.” The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of certain market risks. The Company manages interest rate risk through the use of derivative instruments, such as swap agreements. A swap agreement is a contract between two parties to exchange cash flows based on specified underlying notional amounts, assets and/or indices. The Company does not enter into derivative financial instruments for trading purposes. The accounting for gains and losses that result from changes in the fair values of derivative instruments depends on whether the derivatives have been designated and qualify as hedging instruments and the type of hedging relationships. The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in Accumulated other comprehensive income and are reclassified into the line item in the Consolidated Statements of Comprehensive Loss in which the hedged items are recorded in the same period the hedged items affect earnings. The Company formally assesses whether the financial instruments used in hedging transactions are effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized into earnings. The fair value is based

For the year ended December 31, 2022, the Company recorded $7.9 million and $1.1 million of depreciation expense in Cost of revenues and Selling, general and administrative expense, respectively. Aircraft are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. In 2023, the Company noted that increasing maintenance costs associated with three of our Twin Commander aircraft and the lack of customers for our two Aurora eVTOL Skiron drone aircraft indicated that these aircraft were not viable contract operating planes, resulting in anticipated cash flow losses as a result of being unable to generate revenues. The Company believes the lack of cash flow and continued maintenance expenditures render the carrying amount of the aircraft unrecoverable. For the year ended December 31, 2023, the Company recorded associated impairment charges of $2.4 million in Selling, general and administrative expense in the Consolidated Statements of Operations. For the year ended December 31, 2022, the Company recorded no impairment charges. For the years ended December 31, 2023 and 2022, the Company recorded losses on disposals of assets of $1.2 million and $1.8 million, respectively, in Selling, general and administrative expense in the Consolidated Statements of Operations. For the years ended December 31, 2023 and 2022, capitalized interest to equipment from debt financing was $1.2 million and $0.7 million, respectively. Aircraft that was being manufactured was considered construction in process and was not depreciated until the aircraft was placed into service.

Business Combination and Asset Acquisition [Abstract]
Acquisition Activity	NOTE 10 – ACQUISITION ACTIVITY On September 12, 2023, the Company completed the acquisition of all outstanding equity interests of Ignis Technologies, Inc. (“Ignis”), a fire technology company developing mission-critical intelligence and technology solutions for firefighting organizations, for total consideration of $11.6 million, payable in unregistered shares of Bridger’s Common Stock, consisting of $3.3 million payable at closing (the “Acquisition”). At closing, 426,531 restricted shares of Common Stock were issued to the Ignis shareholders (determined based upon a volume-weighted average per-share price (“VWAP”) of the Common Stock for the 30 consecutive trading days ended September 11, 2023). The remaining $8.3 million of Common Stock consideration is contingent upon the achievement of certain operational milestones and, assuming achievement of such milestones, will be issued to the Ignis shareholders in 2024, 2025, and 2026, with the price per share determined based upon a trailing 120-day VWAP of the Common Stock at the time of each issuance. All of the shares of Common Stock to be issued in the Acquisition will be subject to transfer restrictions for a 12-month period after each issuance, with 1/12th of the total shares of Common Stock vesting each month over the one-year period after each issuance. None of the shares of Common Stock issued or issuable in connection with the Acquisition were registered under the Securities Act of 1933, as amended (the “Securities Act”), on the Acquisition date in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act. Recipients of shares of Common Stock in connection with the Acquisition will have customary resale registration rights with respect to such shares of Common Stock pursuant to the terms and conditions of the Acquisition. The Company accounted for the Acquisition under the acquisition method of accounting and has reported the results of operations of the Acquisition as of the respective date of the Acquisition. The Company based the estimated fair values of intangible assets on an income approach utilizing the relief from royalties model. The income approach utilizes management’s estimates of future operating results and cash flows using a weighted average cost of capital that reflects market participant assumptions. For all other assets acquired and liabilities assumed, the fair value reflects the carrying value of the asset or liability due to their short maturity. The Company recorded the excess of the fair value of the consideration transferred in the Acquisition over the fair value of net assets acquired as goodwill. The goodwill reflects our expectations of favorable future growth opportunities. The Company expects that substantially all of the goodwill will not be deductible for federal income tax purposes. Acquisition-related costs associated with the Acquisition of $0.1 million are included in Selling, general and administrative expense on the Consolidated Statements of Operations for the year ended December 31, 2023. The Company has not presented pro forma combined results for the Acquisition because the impact on previously reported statements of operations was not material. As of December 31, 2023, the Company finalized the purchase accounting for the Acquisition. The following table summarizes the final purchase price allocation: $s in thousands Purchase Price Allocation Cash and cash equivalents $ 3 Intangible assets 1,300 Accounts payable (37) Long-term accrued expenses and other noncurrent liabilities (67) Deferred tax liability (314) Total identifiable net assets 885 Goodwill 10,676 Total purchase price $ 11,561 Goodwill of $10.7 million arising from the acquisition is primarily attributable to the assembled workforce of Ignis and expected synergies from combining operations. None of the acquired goodwill is expected to be deductible for income tax purposes. Acquired intangible assets consist entirely of in-process research and development (“IPR&D”) and is expected to be amortized over its useful life of five years when placed into service. The Company concluded that the IPR&D is an identifiable intangible asset that would be accounted for as a single asset in a business combination. The fair value of the IPR&D was determined using an income approach based on significant unobservable inputs.

The Company expects to amortize the IPR&D over its useful life of five years when placed into service. As of December 31, 2023, the Company capitalized costs of $0.3 million related to IPR&D. Amortization expense for intangible assets and other noncurrent assets was $0.1 million for the years ended December 31, 2023 and 2022, respectively. Amortization expense is included in Selling, general and administrative expense in the Consolidated Statements of Operations.

(“BAE”), in September 2023 via a public tender process from the Government of Spain for €40.3 million. Under the terms of the agreements, the Company agreed to sell its entire outstanding equity interest in BAE to MAB and purchase $4.0 million of non-voting Class B units of MAB. The Company also entered into a services agreement with MAB whereby the Company will manage the return to service upgrades of the Spanish Scoopers through the Company’s wholly-owned Spanish subsidiary, Albacete Aero, S.L., while they are owned and funded by MAB. The service agreement also provides that the Company has the right, but not the obligation, to acquire each Spanish Scooper as it is ready to be contracted and returned to service. The Company assessed both MAB and BAE for variable interest entity accounting under ASC 810-10-15 and determined that MAB is a voting interest entity and BAE is a variable interest entity. However, neither entity is consolidated in the consolidated financial statements as the Company does not have a controlling financial interest in MAB and the Company is not the primary beneficiary of BAE. The Company accounts for its investment in MAB in accordance with ASC 321 as the Company determined that it did not have significant influence as its interests in MAB are non-voting and the Company does not have representation on the Board of Directors of MAB, which makes all significant decisions. Because MAB is privately held and there is no readily determinable fair value for its stock, the Company will avail itself of the accounting alternative provided by ASC 321 whereby the investment will be accounted for at cost less impairment charges, adjusted for observable price changes in orderly transactions for an identical or similar investment in MAB. Investment in Overwatch Imaging, Inc. On February 22, 2022, the Company entered into a collaboration agreement (the “Collaboration Agreement”) with Overwatch Imaging, Inc. (“Overwatch”), a Delaware corporation, under which the Company and Overwatch collaborate to develop and implement the technical and imaging needs of the Company. Overwatch agrees to provide the products and services at a discount to the Company under the Collaboration Agreement. Overwatch’s products and services under the Collaboration Agreement include, but not limited to, imaging systems, software engineer labor related to software-as-a-service support, labor related to sensor operations, and cloud-based image data web service. The Collaboration Agreement will end upon termination by (i) a mutual agreement between the Company and Overwatch, (ii) either or both parties upon revenue payment to Overwatch not meeting certain thresholds stipulated in the Collaboration Agreement within the second, third, or fourth anniversary of the effective date of the Collaboration Agreement, or (ii) either party upon a material breach of the Collaboration Agreement uncured within thirty (30) days after written notice from the non-breaching party. The Company determined that both the Company and Overwatch are active participants and exposed to the significant risks and rewards of the collaboration under the Collaboration Agreement. The Company does not consider its obligations under the Collaboration Agreement as an output of the Company’s ordinary activities in exchange for consideration and Overwatch is not considered a customer under ASC 606. Therefore, the Company considers the collaboration to be within the scope of ASC 808. For the years ended December 31, 2023 and 2022, the Company recorded zero and $0.8 million, respectively, of purchases of imaging systems under the Collaboration Agreement in Property, plant and equipment, net, and $39,000 and $0.4 million, respectively of engineering services provided by Overwatch under the Collaboration Agreement in Selling, general and administrative expense.

The Company’s bonus pool was accrued throughout the year and was based upon 2022 performance milestones. On August 19, 2022, the Company also granted $10.1 million of discretionary cash bonuses to employees and executives in connection with the issuance of the Legacy Bridger Series C Preferred Shares, issuance of the Series 2022 Bonds for $160.0 million and execution of the Transaction Agreements. Warrant liabilities The warrant liabilities consist of the following Warrants issued by the Company in connection with the Reverse Recapitalization: Public Warrants The Company issued Public Warrants to purchase 17,250,000 shares of Common Stock at an exercise price of $11.50 per share in exchange for the 17,250,000 JCIC warrants originally issued by JCIC in its initial public offering. The Warrants may only be exercised for a whole number of shares of Common Stock. The exercise price and number of shares of Common Stock issuable upon exercise of the Warrants may also be adjusted in certain circumstances including in the event of a share dividend, recapitalization, reorganization, merger or consolidation. In no event will the Company be required to net cash settle any Warrant. The Warrants became exercisable 30 days following the Reverse Recapitalization and will expire January 24, 2028. Under certain circumstances, the Company may elect to redeem the Public Warrants at a redemption price of $0.01 per Public Warrant at any time during the term of the warrant in which the Common Stock trading price has been at least $18.00 per share for 20 trading days within the 30 trading-day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the Warrant holders. If the Company elects to redeem the Public Warrants, it must notify the Public Warrant holders in advance, who would then have at least 30 days from the date of notification to exercise their respective warrants. If the warrant is not exercised within that 30-day period, it will be redeemed pursuant to this provision. The Company may also elect to redeem the outstanding Warrants at a redemption price of $0.10 per Warrant at any time during the term of the Warrant in which the Common Stock trading price is between $10.00 per share and $18.00 per share (as adjusted for share splits, share dividends, rights issuances, subdivisions, reorganization, recapitalizations and the like) for any 20 trading days within the 30 trading-day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the Warrant holders. In such case, the Warrant holders will be able to exercise their Warrants on a cashless basis prior to the redemption for a number of shares of our Common Stock determined based on the redemption date and the fair market value of the Common Stock. As of December 31, 2023, 17,249,874 Public Warrants remain outstanding. The Public Warrants are liability-classified with a balance of $3.6 million and a fair value of $0.21 per warrant as of December 31, 2023. Private Placement Warrants The Company issued Private Placement Warrants to purchase 9,400,000 shares of Common Stock at an exercise price of $11.50 per share in exchange for the 9,400,000 JCIC warrants originally purchased in a private placement by JCIC Sponsor, LLC (“JCIC Sponsor”) contemporaneously with JCIC’s initial public offering. JCIC Sponsor, or its permitted transferees, has the option to exercise the Private Placement Warrants on a cashless basis. If the Private Placement Warrants are held by holders other than JCIC Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company in all redemption scenarios and exercisable by the holders on the same basis as the Public Warrants. As of December 31, 2023, the Company had 9,400,000 outstanding Private Placement Warrants to purchase 9,400,000 shares of Common Stock. The Private Placement Warrants are liability-classified with a balance of $2.0 million and a fair value of $0.21 per warrant as of December 31, 2023. Contingent consideration The Company assumed Contingent consideration as part of the Acquisition discussed in “Note 10 – Acquisition Activity.” The Company is required to make contingent payments to the sellers based on the achievement of certain operational milestones. The fair value of the liability for the contingent payments was recognized upon the acquisition as part of the purchase accounting opening balance sheet. The initial cost was recognized at fair value on the closing date with subsequent changes in estimated fair value recognized as Selling, general and administrative expenses in the Consolidated Statements of Operations. As of December 31, 2023, the Company recognized $4.8 million in Accrued expenses and other current liabilities and $3.6 million in Long-term accrued expenses and other noncurrent liabilities in the Consolidated Balance Sheets.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Swap and Freestanding Derivative	NOTE 14 – INTEREST RATE SWAP AND FREESTANDING DERIVATIVE The Company assesses interest rate cash flow risk by continually identifying and monitoring changes in interest rate exposures that may adversely affect expected future cash flows and by evaluating hedging opportunities. The Company entered an interest rate swap with Rocky Mountain Bank (“RMB”) on March 12, 2020 to reduce risk related to variable-rate debt from the term loan, which was subject to changes in market rates of interest as discussed in “Note 16 – Long-Term Debt . ” The interest rate swap is designated as a cash flow hedge. The Company records its corresponding derivative asset on a gross basis in Other noncurrent assets at fair value on the Consolidated Balance Sheets. Each month, the Company made interest payments to RMB under its loan agreement based on the current applicable one-month LIBOR rate plus the contractual LIBOR margin then in effect with respect to the term loan, without reflecting the interest rate swap until June 30, 2023. Effective July 1, 2023, LIBOR was replaced by 1-month CME Term Secured Overnight Financing Rate (“SOFR”) plus 0.11448% tenor spread adjustment plus the 2.5% contractual SOFR margin then in effect with respect to the term loan. At the end of each calendar month, the Company receives or makes payments on the interest rate swap difference, if any, based on the received interest rate set forth in the table below. Interest payments on the Company’s term loan and payments received or made on the interest rate swap are reported net on the Consolidated Statements of Operations as interest expense. The Company had the following interest rate swap designated as a cash flow hedge ($s in thousands): As of December 31, 2023 Effective Maturity Notional Fair Value Pay Fixed Receive Rate 4/15/2020 3/15/2030 $ 10,466 $ 1,117 3.887 % 1 Month SOFR + 2.61448% As of December 31, 2022 Effective Maturity Notional Fair Value Pay Fixed Receive Rate 4/15/2020 3/15/2030 $ 11,110 $ 1,407 3.887 % 1 Month LIBOR + 2.5% The Company accounts for the interest rate swap as a cash flow hedge for accounting purposes under GAAP. The Company reflects the effect of this hedging transaction in the consolidated financial statements. The unrealized gain is reported in other comprehensive (loss) income. If the Company terminates the interest rate swap agreement, the cumulative change in fair value at the date of termination would be reclassified from Accumulated other comprehensive income, which is classified in stockholders’ deficit, into earnings in the Consolidated Statements of Operations. Freestanding Derivative On April 9, 2022, JPMorgan Chase Funding Inc. (“JPMCF”) entered into a letter agreement with the Company to receive an excess hold fee of 5% of the aggregate initial stated value of the Legacy Bridger Series C Preferred Shares held by JPMCF in excess of $157,894,736.84 as of March 15, 2023. The excess hold fee was considered a freestanding derivative instrument until March 15, 2023 and became a fee payable thereafter. The Company paid $1.1 million and the remaining $1.1 million of the excess hold fee in June and July 2023, respectively. As of December 31, 2022, the fair value of the freestanding derivative on Legacy Bridger Series C Preferred Shares was $2.2 million. Realized gains and losses arising from changes in fair value of the freestanding derivative were recorded in earnings.

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 15 – FAIR VALUE MEASUREMENTS Long-term debt As of December 31, 2023, the Company has $160.2 million of fixed rate and $51.2 million of variable rate debt outstanding. Based on current market rates, the fair value of the fixed rate debt as of December 31, 2023 was estimated to be $174.7 million. The Company estimated the fair value of the fixed rate debt using quoted market prices (Level 2 inputs) within the fair value hierarchy. When valuing fixed rate debt, the fair value is capped at par value. The variable rate debt approximates fair value based on the closing or estimated market prices of similar securities comparable to the Company’s debts as of December 31, 2023 and 2022. Debt financing activities and loan agreements are further described in “Note 16 – Long-Term Debt.” Recurring Fair Value Measurement Our cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and other current assets and liabilities (excluding derivative instruments) are carried at amounts which reasonably approximate their fair values due to their short-term nature. The following tables summarizes the Company’s assets and liabilities that are measured at fair value on a recurring basis, by level, within the fair value hierarchy: As of December 31, 2023 $s in thousands Level 1 Level 2 Level 3 Assets Cash $ 22,956 $ — $ — Restricted cash: Money market fund 13,981 — — Total restricted cash 13,981 — — Investments in marketable securities — 1,009 — Interest rate swap — 1,117 — Total assets $ 36,937 $ 2,126 $ — Liabilities Warrant liabilities - Public Warrants 3,622 — — Warrant liabilities - Private Placement Warrants — 1,974 — Contingent consideration — — 8,486 Embedded derivative of Series A Preferred Stock — — 885 Total liabilities $ 3,622 $ 1,974 $ 9,371 As of December 31, 2022 ($s in thousands) Level 1 Level 2 Level 3 Assets Cash $ 260 $ — $ — Cash equivalents: Commercial paper — 29,890 — Money market fund 13 — — Total cash and cash equivalents 273 29,890 — Restricted cash: Money market fund 9,284 — — Other restricted cash 3,013 — — Total restricted cash 12,297 — — Investments in marketable securities — 54,980 Interest rate swap — 1,407 — Total assets $ 12,570 $ 86,277 $ — Liabilities Freestanding derivative on Legacy Bridger Series Preferred Shares $ — $ — $ 2,186 Embedded derivative of Legacy Bridger Series C Preferred Shares — — 1,040 Total liabilities $ — $ — $ 3,226 Interest Rate Swap The Company’s derivative financial instruments are measured at fair value on a recurring basis based on quoted market prices or using standard valuation models as described in “Note 14 – Interest Rate Swap and Freestanding Derivative.” The notional amounts of the derivative financial instruments do not necessarily represent amounts exchanged by the parties and, therefore, are not a direct measure of our exposure to the financial risks described in “Note 2 – Summary of Significant Accounting Policies.” The fair value of the Company’s interest rate swap agreement was determined based on the present value of expected future cash flows using discount rates appropriate with the terms of the swap agreement. The fair value indicates an estimated amount the Company would be required to receive if the contracts were canceled or transferred to other parties. The Company calculates the fair value of interest rate swap agreement quarterly based on the quoted market price for the same or similar financial instruments. The fair value of the freestanding derivative was determined based on the present value of the excess hold fee expected to be owed on March 15, 2023, after taking into account the probability of such excess hold fee being outstanding on the same date. The excess hold fee was considered a freestanding derivative instrument until March 15, 2023 and became a fee payable thereafter, noted above as an excess hold fee payable on Series A Preferred Stock. The Company used a Level 3 valuation methodology to measure this freestanding derivative. Mandatorily Redeemable Legacy Bridger Series B Preferred shares The Company’s mandatorily redeemable Legacy Bridger Series B Preferred Shares are measured at fair value based on capital contributions, plus accrued but unpaid interest. The Legacy Bridger Series B Preferred Shares were redeemed during the year ended December 31, 2022 as furthered discussed in “Note 21 – Mandatorily Redeemable Preferred Shares.” Embedded derivative of Legacy Bridger Series C Preferred Shares and Series A Preferred Stock The Company identified a redemption feature of the Legacy Bridger Series C Preferred Shares that required bifurcation from the host instrument as an embedded derivative liability, as discussed in “Note 20 – Mezzanine Equity.” The embedded derivative was initially valued and remeasured using a “with-and-without” method. The “with-and-without” methodology involved valuing the entire instrument both with and without the embedded derivative using a discounted cash flow approach. Under this methodology, the difference in the estimated fair value between the instrument with the embedded derivative and the instrument without the embedded derivative represents the estimated fair value of the embedded derivative. This valuation methodology is based on unobservable estimates and judgements, and therefore is classified as a Level 3 fair value measurement. The significant unobservable input used in the estimated fair value measurement of the embedded derivative is the timing for which the Company may be in default of certain financing facilities that would require an increase of 2% interest per annum to be accrued by the holders of the Legacy Bridger Series C Preferred Shares. Legacy Bridger Series C Preferred Shares were re-issued as Series A Preferred Stock as part of the Closing, as further discussed in “Note 20 – Mezzanine Equity.” Commercial Paper and Investments in marketable securities The fair values of the commercial paper and available-for-sale marketable securities are based on observable market prices, and therefore classified as a Level 2 fair value measurement. Refer to “Note 5 – Cash Equivalents and Investment in Marketable Securities” included in this Annual Report on Form 10-K for additional details. Warrant Liabilities The Company issued Warrants in connection with the Reverse Recapitalization. The Company classifies the Warrants as liabilities at their fair value and adjust the Warrants to fair value at each reporting period. The warrant liabilities are subject to remeasurement at each balance sheet date until exercised, and any change in fair value are recorded in earnings through Selling, general and administrative expense on the Consolidated Statements of Operations. The Public Warrants are publicly traded under the symbol “BAERW,” and the fair value of the Public Warrants at a specific date is determined by the closing price of the Public Warrants as of that date. Therefore, the Public Warrants are classified as Level 1 of the fair value hierarchy. The Public Warrants are redeemable at any time during the term of the warrant in which the Common Stock share trading price has been at least $18.00 per share for 20 trading days within the 30 trading-day period. JCIC Sponsor can redeem both the Private Placement Warrants and the Public Warrants when the stock price is between $10.00 to $18.00. As such, it is economically beneficial for the Company to redeem the Private Placement Warrants any time before the stock price crosses the $18.00 threshold. Therefore, the Warrants have similar economic value, hence Private Placement Warrants are deemed to have the same value as the Public Warrants and are classified Level 2 of the fair value hierarchy. Refer to “ Note 13 – Accrued Expenses and Other Liabilities ” included in this Annual Report on Form 10-K for additional details. Contingent Consideration In connection with the Acquisition, the Company is required to make contingent payments to the sellers based on the achievement of certain operational milestones. The fair value of the liability for the contingent payments recognized upon the acquisition as part of the purchase accounting opening balance sheet totaled $8.3 million. The fair value of the contingent consideration was determined using the Monte-Carlo simulation-based model discounted to present value. Assumptions used in this calculation are equity volatility, estimated future stock prices and various probability factors, including management’s estimate of the likelihood of meeting certain operational milestones. The ultimate settlement of the contingent consideration could deviate from current estimates based on the actual results of these financial measures. This liability is considered to be a Level 3 financial liability that is remeasured each reporting period. Changes in estimated fair value of contingent consideration are recognized as Selling, general and administrative expenses within the Unaudited Condensed Consolidated Statements of Operations. Refer to “ Note 13 – Accrued Expenses and Other Liabilities ” included in this Annual Report on Form 10-K for additional details. Non-Recurring Fair Value Measurements The Company measures certain assets at fair value on a non-recurring basis, including long-lived assets and goodwill and cost and equity method investments, which are evaluated for impairment. Long-lived assets include property, plant and equipment, net, and certain intangible assets. The inputs used to determine the fair value of long-lived assets are considered Level 3 measurements due to their subjective nature. As of December 31, 2023, the Company recorded impairment charges of $2.4 million related to three of our Twin Commander aircraft and our two Aurora eVTOL Skiron drone aircraft. As of December 31, 2022, the Company did not have any other significant assets or liabilities that were remeasured at fair value on a non-recurring basis in periods subsequent to initial recognition. Refer to “ Note 9 – Property, Plant and Equipment, Net ” included in this Annual Report on Form 10-K for additional details.

The proceeds were designated to redeem in full the 2021 Bonds and the Series A Preferred shares, to finance the construction and equipping of the Company’s third and fourth aircraft hangar in Belgrade, Montana and to fund the purchase of additional CL-415EAF aircraft. The Series 2022 Bonds mature on September 1, 2027, with an annual interest rate of 11.5% payable semiannually on March 1 and September 1 of each year, commencing on September 1, 2022. Debt issuance costs for the Series 2022 Bonds were $4.2 million. The Series 2022 Bonds are subject to redemption or prepayment prior to maturity, as follows: (a) optional redemption in whole or in part, on any day thereafter at par plus accrued interest, and on certain dates, a premium; (b) mandatory redemption at par plus any premium applicable to optional redemptions and a 3% premium if such redemptions are made prior to September 1, 2025, in whole or in part, in the event of the occurrence of certain events; and (c) extraordinary redemption at par plus accrued interest due to the occurrence of certain casualty, condemnation, or other unexpected events. Optional redemptions are subject to 3%, 2%, and 0% premiums if redemptions are made on or after September 1, 2025, September 2026, and September 2027, respectively. At the Company’s direction, the Series 2022 Bonds may be redeemed by Gallatin County at any time, at a redemption price equal to 100% of the principal amount plus accrued interest upon the occurrence of certain events 2 In 2020, the Company entered into two separate credit facilities brokered through Live Oak Bank (“LOB”) and backed by the US Department of Agriculture for the completed purchase of the Company’s first two Viking CL-415EAF aircraft. The Company issued two $19.0 million promissory notes to LOB, established as 15-year maturity, first two years interest only payments monthly, then 13-year term principal plus interest due monthly at the rate of the greater of prime plus 1.5% or 4.75% per annum. The first of these notes was issued on August 21, 2020 and the second was issued October 1, 2020 to BAT1, LLC and BAT2, LLC, respectively. Debt issuance costs for BAT1 and BAT2 were $1.0 million and $0.9 million, respectively. 3 On September 20, 2019, the Company entered into a credit facility with RMB for $12.9 million, established as a 10-year maturity, 6-month draw period, first 6 months interest only payments monthly, then 10-year term principal plus interest due monthly on a 20-year amortization at the rate of 1 month SOFR plus 2.61448%. Debt issuance costs for this loan were $0.1 million. 4 On February 3, 2020, the Company entered into a credit facility with RMB to finance in part the purchase of four Quest Kodiak aircraft. A promissory note was issued for $5.6 million, established as a 7-year maturity, first 8 months interest only payments monthly, 60 day draw period, then 76-month term plus principal interest due monthly on a 10-year amortization at the rate of 1 month SOFR plus 2.61448%. Debt issuance costs for this loan was $0.1 million. 5 On November 18, 2021, the Company re-entered into a new short-term loan to finance aviation insurance premiums with Insurance Premium Financing Leader. This was financed for $0.6 million with a maturity of one year and at a rate of 3.89%. No debt issuance costs were incurred. The Company also entered into various term loan agreements for the purchase of vehicles through First Interstate Bank with the earliest date of September 9, 2021. These loans ranged from $29,000 to $72,000 and were at rates from 4.8% to 5.5% and at durations from 5 to 6 years, with the latest maturation on November 17, 2027. The Series 2022 Bonds are subject to financial covenants requiring the Company to maintain a DSCR that exceeds 1.25x commencing with the fiscal quarter ending December 31, 2023, operate in such a manner to produce gross revenues so as to be at all relevant times in compliance with the DSCR covenant and to maintain liquidity of $8.0 million in the form of unrestricted cash or investments (excluding margin accounts and retirement accounts) at all times and to be reported. The Company is not in compliance with the DSCR covenant as of December 31, 2023 and management anticipates the Company to continue to not be in compliance with the DSCR covenant at future quarterly measurement periods during the next 12 months, primarily attributable to the seasonal nature of our business and a less intense 2023 wildfire season. Although the Company is in compliance with the $8.0 million minimum liquidity requirement as of December 31, 2023, based on projected cash use, management anticipates that without additional cash funding the Company will not have sufficient cash on hand to comply with the minimum liquidity covenant or to fund operations, including $18.4 million of required interest payments associated with the Series 2022 Bonds, within the next 12 months, until the Company begins to collect cash from its seasonal firefighting operations in 2024. The Series 2022 Bonds agreements provide that, with regard to covenant violations, other than non-payment of principal or interest, no event of default shall be deemed to have occurred so long as a reasonable course of action to remedy a violation commences within 30 days of written notification of non-compliance from the trustee and management diligently prosecutes the remediation plan to completion. Management consulted with bond counsel on the impact of covenant violations and proactively developed a cost reduction plan, and began implementing the plan in November 2023, to help remedy the anticipated covenant breaches in 2024. However, this plan is in progress and there is no assurance that management will be able diligently prosecute the remediation plan to completion. The uncertainty regarding the company’s ability to diligently prosecute the remediation plan to completion and the potential impact on the bonds maturity as a result of the anticipated debt covenant violations at subsequent compliance dates or failure to make required interest payments, could result in the Series 2022 Bonds becoming immediately due and payable, which raises substantial doubt about our ability to continue as a going concern as further disclosed in “ Note 1 – Organization and Basis of Presentation. ” The LOB loans are subject to financial covenants requiring the Company to maintain a DSCR, generally calculated as the ratio of the net cash flow (as defined in the applicable note agreements) to the amount of interest and servicing fees required to be paid over the succeeding 12 months on the principal amount of the note, as applicable, that will be outstanding on the payment date following such date of determination, that exceeds 1.25x at the aircraft or entity level and for the Company’s debt to worth ratio to not exceed 5.00x at the aircraft or entity level. The Company is in compliance with such financial covenants as of December 31, 2023. Both of the loans with RMB are subject to financial covenants requiring the Company to maintain a DSCR, calculated as the ratio of adjusted EBITDA (as defined in the applicable note agreements) to the amount of interest and principal payments for the fiscal year ending on the compliance date, that exceeds 1.25x for the Company. These notes are also subject to financial covenants requiring the Company to maintain a Senior Leverage Ratio on a quarterly basis not to exceed 7.00 to 1.00 through Quarter 3, 2024, 6.00 to 1.00 through Quarter 3, 2025 and 5.00 to 1.00 thereafter. This is calculated as Total Funded Senior Debt (as defined in the applicable note agreements) less municipal debt, divided by adjusted EBITDA (as defined in the applicable note agreements). As of December 31, 2022, the Company was in compliance with the Senior Leverage Ratio requirement related to the credit facilities entered with RMB, as RMB amended the loan agreements prior to year-end. These amendments modified the definition of EBITDA to be used in the Senior Leverage Ratio calculation to include certain allowable addbacks and modified the timing requirement of the Senior Leverage Ratio. The Company is in compliance with such financial covenants as of December 31, 2023. Amortization of debt issuance costs was $1.0 million and $0.6 million for the years ended December 31, 2023 and 2022, respectively. Principal maturities of the outstanding debt as of December 31, 2023 are as follows: $ in thousands Maturities 2024 $ 2,993 2025 3,193 2026 3,396 2027 165,149 2028 3,232 Thereafter 33,411 Total $ 211,374

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 17 – COMMITMENTS AND CONTINGENCIES Legal Matters From time to time, the Company is subject to various litigation and other claims in the normal course of business. No amounts have been accrued in the consolidated financial statements with respect to any matters. Due to the nature of our business, we may become, from time to time, involved in routine litigation or subject to disputes or claims related to our business activities. In the opinion of our management, there are no pending litigation, disputes or claims against us which, if decided adversely, will have a material adverse effect on our financial condition, cash flows or results of operations. In the ordinary course of its operations, the Company will continue to vigorously enforce its legal and contractual rights to ensure that its business and operations continue on an unimpaired basis. Commitments On April 13, 2018, the Company executed an aircraft purchase agreement with Longview Aviation Asset Management, Inc. and Viking Air Limited (“Viking”) for the purchase of six Viking CL-415EAF aircraft. For the year ended December 31, 2022, the Company paid $9.1 million and received its sixth Viking CL-415EAF, the final remaining aircraft under the aircraft purchase agreement, in 2023. Uninvoiced commitments were zero and $9.1 million as of December 31, 2023 and 2022. On March 23, 2022, the Company entered into an agreement with Sievert Construction, Inc for the construction of a hangar at the Bozeman Yellowstone International Airport in Belgrade, Montana. Payments made under the agreement were $3.2 million and $9.8 million for the years ended December 31, 2023 and 2022, respectively. Un-invoiced commitments were zero and $3.8 million as of December 31, 2023 and 2022. Leases Under ASC 842, leases are separated into two classifications: operating leases and financial leases. Lease classification under ASC 842 is relatively similar to ASC 840. For a lease to be classified as a finance lease, it must meet one of the five finance lease criteria: (1) transference of title/ownership to the lessee, (2) reasonably certain to exercise a purchase option, (3) lease term for major part of the remaining economic life of the asset, (4) present value represents substantially all of the fair value of the asset and (5) asset specialization. Any lease that does not meet these criteria is classified as an operating lease. ASC 842 requires all leases to be recognized on the Company’s balance sheet. Specifically, for operating leases, the Company recognizes a right-of-use asset and a corresponding lease liability upon lease commitment. Company as a lessee The Company is the lessee in a lease contract when the Company obtains the right to use the asset. The right-of-use asset represents the Company’s right to use an underlying asset for the lease term and lease obligations represent the Company’s obligations to make lease payments arising from the lease, both of which are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company has also elected the short-term lease exception whereby leases with a term of 12 months or less at inception are not recorded on the Consolidated Balance Sheets and are expensed on a straight-line basis over the lease term in our Consolidated Statements of Operations. The Company determines the lease term by agreement with the lessor. Options to renew are considered in lease terms if reasonably expected to be exercised. ASC 842 requires a lessee to use the rate implicit in the lease whenever that rate is readily determinable, otherwise the incremental borrowing rate (“IBR”) should be used. Given the nature of the Company’s lease portfolio, which consists of leases of hangar spaces, aircraft, vehicles, copiers, buildings, aircraft equipment, the implicit rate is often unavailable. In such cases, the Company uses its incremental borrowing rate as the discount rate. The IBR is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. The determination of the IBR requires judgment and is derived from the Company’s weighted average cost of capital. Components of the Company’s operating and finance lease assets and liabilities as of December 31, 2023 and 2022 are as follows: As of December 31, $s in thousands Financial Statement Line Item 2023 2022 Assets Operating lease right-of-use asset Other noncurrent assets $ 7,777 $ 671 Finance lease right-of-use asset, net Property, plant and equipment, net 40 62 Liabilities Operating lease right-of-use liabilities (current) Operating right-of-use liability (current) $ 2,153 $ 21 Finance lease right-of-use liabilities (current) Accrued expenses and other current liabilities 22 23 Operating lease right-of-use liabilities (non-current) Operating right-of-use liability (noncurrent) 5,779 755 Finance lease right-of-use liabilities (non-current) Accrued expenses and other noncurrent liabilities 24 46 The Company leases various property and premises on a short-term basis and leases some of its premises under non-cancelable operating leases that expire on various dates through January 2051.

The terms of the agreements provide that the Company will manage the return to service upgrades of the Spanish Scoopers while they are owned and funded by MAB. The Company has the right, but not the obligation, to acquire each plane as it is ready to be contracted and returned to service. In the event that Bridger does not purchase the aircraft within the time periods set forth in the agreements, then either party may initiate a sales process for the sale of all aircraft that have not been purchased by the Company, which sales process the Company will oversee and manage. If the aircraft are sold to a third party through such process, then the Company must pay the MAB’s subsidiary a cash fee equal to the amount, if any, by which the aggregate price of the Company’s purchase options for such aircraft exceeds the consideration paid by the third-party purchaser for the same aircraft, not to exceed $15.0 million in aggregate. If the aircraft are not sold to a third party and MAB’s subsidiary has not otherwise entered into an operating lease with a third party for the aircraft, then the Company must pay MAB’s subsidiary $15.0 million.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	NOTE 18 – STOCK-BASED COMPENSATION Incentive Units During the year ended December 31, 2022, the Company granted Incentive Units to selected board members and executives. Within each grant, 80% of the Incentive Units vest annually over a four year period subject to continued service by the grantee (the “Time-Vesting Incentive Units”), and the remaining 20% of the Incentive Units vest upon a qualifying change of control event (the “Exit-Vesting Incentive Units”). Notwithstanding the above, any unvested Time-Vesting Incentive Units will become vested if a qualifying change of control event occurs prior to the respective award’s four year service-based vesting period. Upon termination of the board member or executive, the Company has the right, but not the obligation, to repurchase all or any portion of the vested Incentive Units at fair market value. Upon vesting of each Incentive Unit, the Company will issue 0.96246 shares of Common Stock to the Incentive Unit holder. For the Time-Vesting Incentive Units, compensation cost is recognized over the requisite service period on a straight-line basis. Upon a qualifying change of control event, the unrecognized compensation expense related to the Time-Vesting Incentive Units will be recognized when the change of control event is considered probable. For the Exit-Vesting Incentive Units, expense is recognized when a qualifying change of control event is considered probable, which has not occurred as of December 31, 2023. Forfeitures are accounted for as they occur. Compensation cost for the Incentive Units is measured at their grant-date fair value. The fair value of the Company’s Incentive Units was derived through an option pricing model, which incorporated various assumptions. Use of a valuation model required management to make certain assumptions with respect to selected model inputs. Expected volatility was calculated based on the observed equity volatility for comparable companies. The expected time to liquidity event was based on management’s estimate of time to an expected liquidity event. The dividend yield was based on the Company’s expected dividend rate. The risk-free interest rate was based on U.S. Treasury zero-coupon issues. The weighted-average assumptions the Company used in the option pricing model for 2022 are as follows: Dividend yield 0 % Expected volatility 46.5 % Risk-free interest rate 1.26 % Term 5.00 years Discount for lack of marketability 30 % Incentive Unit activity for the period from January 1, 2023 to December 31, 2023 is as follows: Time-Vesting Incentive Units Exit-Vesting Incentive Units Number of Weighted Number of Weighted Outstanding as of December 31, 2022 161,616 $ 0.17 80,808 $ 0.11 Granted — — — — Vested (40,404) 0.01 — — Forfeited (121,212) 0.22 (40,404) 0.22 Outstanding as of December 31, 2023 — $ — 40,404 $ 0.01

Mezzanine Equity	NOTE 20 – MEZZANINE EQUITY Legacy Bridger Series C Preferred Shares On April 25, 2022, Legacy Bridger authorized and issued 315,789.473684 Legacy Bridger Series C Preferred Shares for aggregate proceeds of $288.5 million, net of issuance costs of $11.5 million. The Legacy Bridger Series C Preferred Shares ranked senior to Legacy Bridger’s common shares and ranked subordinate to Legacy Bridger Series A Preferred Shares, which were later redeemed in 2022, with respect to the distribution of assets upon liquidation or certain triggering events. The Legacy Bridger Series C Preferred Shares did not participate in earnings of Legacy Bridger and were non-voting shares. Prior to the consummation of the qualified public offering, the Legacy Bridger Series C Preferred Shares accrued interest daily at 7% per annum for the first year, 9% per annum for the second year and 11% per annum thereafter and were compounded semi-annually at June 30th and December 31st of each year. Following the consummation of a qualified public offering, the Legacy Bridger Series C Preferred Shares were to accrue interest daily at 7% per annum for the first 6 years, 9% per annum for the seventh year and 11% per annum thereafter, compounded semi-annually. Accrued interest for the Legacy Bridger Series C Preferred Shares was $15.3 million as of December 31, 2022 recorded to increase the redemption amount in mezzanine equity. Upon the Closing, Legacy Bridger surrendered and exchanged all 315,789.473684 issued and outstanding Legacy Bridger Series C Preferred Shares into 315,789.473684 shares of Series A Preferred Stock. The Company’s Certificate of Incorporation included provisions of the Legacy Bridger Series C Preferred Shares that were already in effect prior to the consummation of the Reverse Recapitalization . As a result of the Reverse Recapitalization , the maximum redemption value of the Company’s Series A Preferred Stock changed to approximately $332.7 million and excluded the 50% multiplier which had historically been included in the maximum redemption value of Legacy Bridger Series C Preferred Shares. The Legacy Bridger Series C Preferred Shares were convertible at the election of the holder into shares of Legacy Bridger’s Class B common shares after the occurrence of certain specified events, including after a qualified public offering, without the payment of additional consideration by the holder into such number of Legacy Bridger Class B common stock as determined by dividing the original issue price, plus accrued interest by a conversion price in effect at the time of conversion. The conversion price of Legacy Bridger Series C Preferred Shares was initially equal to $12.929104. The applicable conversion price was subject to future adjustments upon the occurrence of a qualified public offering. The Legacy Bridger Series C Preferred Shares were mandatorily redeemable by Legacy Bridger on April 25, 2032 at an amount dependent on whether the redemption occurs prior or following a qualified public offering. If the mandatory redemption occurs prior to the consummation of a qualified public offering, the redemption amount was equal to the stated value, plus the initial issue price multiplied by 50%, plus accrued but unpaid interest. If the mandatory redemption occurs following the consummation of a qualified public offering, the redemption amount was equal to the stated value, plus accrued but unpaid interest. The Legacy Bridger Series C Preferred Shares were also redeemable upon certain triggering events outside of the control of Legacy Bridger. The redemption events include redemption by the holder after March 29, 2027 and prior to a qualified public offering, or a fundamental change in Legacy Bridger’s voting and governance structure such as the sale of Legacy Bridger or its subsidiaries representing more than 50% of Legacy Bridger’s voting stock or a similar liquidity event. Given the conversion feature was considered substantive, the mandatory redemption date was not certain and the optional redemption was upon the occurrence of certain events that are considered not solely within Legacy Bridger’s control, the Legacy Bridger Series C Preferred Shares were classified as mezzanine equity. The Company identified certain conversion and redemption features that are required to be bifurcated from the host instrument as embedded derivative liabilities. The Legacy Bridger Series C Preferred Shares contained a clause which allowed for an increase of 2% interest per annum to be accrued by the holders of the Legacy Bridger Series C Preferred Shares in the event of a default under certain financing facilities, including noncompliance with certain financial covenants, during the period from 30 days after the occurrence of such default until such default was cured or remediated. The Company expected to be exposed to the 2% interest rate increase for no more than 2 months. As of December 31, 2022, the fair value of the embedded derivative was $1.0 million recorded as a liability in the Condensed Consolidated Balance Sheets and remeasured to fair value at each balance sheet date with changes in fair value recorded within Interest expense in the Condensed Consolidated Statements of Operations. The Company also entered into a letter agreement with JPMCF on April 9, 2022 to pay an excess hold fee of 5% of the aggregate initial stated value of the Legacy Bridger Series C Preferred Shares held by JPMCF in excess of $157,894,736.84 as of March 15, 2023. Further details of the freestanding derivative and subsequent excess hold fee payable are described in “Note 14 – Interest Rate Swap and Freestanding Derivative.” The Company determined the fair value of the other features requiring bifurcation, both individually and in the aggregate were immaterial at inception and as of December 31, 2022. The fair value of these features will be assessed at each reporting date and will be recognized and remeasured at fair value, if material. As of December 31, 2022, it was probable that the Legacy Bridger Series C Preferred Shares may become redeemable at either the holder’s option on or after March 29, 2027 and prior to the consummation of a qualified public offering or in the event of a qualified public offering. The Company elected to recognize changes in redemption value immediately, adjusting the Legacy Bridger Series C Preferred Shares to the maximum redemption value at each reporting date. As of December 31, 2022, the Legacy Bridger Series C Preferred Shares were carried at their redemption value of $489.0 million. Series A Preferred Stock The Series A Preferred Stock are convertible at the election of the holders into shares of Common Stock, without the payment of additional consideration by the holders into such number of shares of Common Stock as determined by dividing the original issue price, plus accrued interest by a conversion price equal to $11.00 per share at the time of conversion. Shares of Series A Preferred Stock are mandatorily redeemable by the Company on April 25, 2032 at a redemption amount that is equal to the stated value, plus accrued but unpaid interest. Accrued interest for the Series A Preferred Stock was $22.2 million as of December 31, 2023. Shares of Series A Preferred Stock are also redeemable upon certain triggering events outside of the control of the Company. The triggering events include redemption by the holder on or after April 25, 2027, or a fundamental change in the Company’s voting and governance structure such as the sale of the Company or its subsidiaries representing more than 50% of the Company’s voting stock or a similar liquidity event. As of the Closing Date and December 31, 2023, it is probable that the Series A Preferred Stock may become redeemable on April 25, 2032. The Company has elected to recognize changes in redemption value immediately, adjusting the preferred stock to the maximum redemption value at each reporting date. Upon Closing, the Series A Preferred Stock had both a carrying value and redemption value of $332.7 million, the 50% multiplier, valued at $156.4 million, was removed. As of December 31, 2023, the Series A Preferred Stock had both a carrying value and redemption value of $354.8 million. Refer to table below. As of December 31, 2023 the fair value of the embedded derivative related to the event of default is $0.9 million recorded as a liability on the Consolidated Balance Sheets and remeasured to fair value at each balance sheet date with changes in fair value recorded within Interest expense or income on the Consolidated Statements of Operations. The Company determined the fair value of the other features requiring bifurcation, both individually and in the aggregate were immaterial at December 31, 2023. The fair value of these features will be assessed at each reporting date and will be recognized and remeasured at fair value, if material. Additionally, the reduction of the conversion price from $12.90 per share to $11.00 per share triggered a down round conversion feature embedded in the Series A Preferred Stock upon Closing. The Company recognized the value of the effect of a down round feature as a deemed dividend, decreasing income attributable to common stockholders in the computation of the earnings (loss) per share by $48.3 million for the year ended December 31, 2023. As of December 31, 2023, there are 32,258,180 shares of Common Stock issuable upon conversion.

Mandatorily Redeemable Preferred Shares	NOTE 21 – MANDATORILY REDEEMABLE PREFERRED SHARES Legacy Bridger Series B Preferred Shares Legacy Bridger had 60,000,000 shares of Legacy Bridger Series B Preferred shares issued and outstanding as of December 31, 2021 at $1.00 per share. The Legacy Bridger Series B Preferred shares were non-voting and accrued interest at 17.5% per annum, compounded quarterly. A mandatory redemption period was required for the Legacy Bridger Series B Preferred shares plus their accrued interest in March of 2022. The shares were mandatorily redeemable by the Legacy Bridger at an amount equal to the capital contribution, plus accrued but unpaid interest on the earlier of certain redemption events or March 31, 2022. The redemption events included the sale of Legacy Bridger or its subsidiaries representing more than 50% of Legacy Bridger’s voting stock or assets, a qualified IPO or a similar liquidity event. The shares were redeemable at any time at the option of Legacy Bridger at a redemption price equal to face value, plus accrued, but unpaid interest. The shares had preference to the common shares of Legacy Bridger, were non-voting and did not participate in the earnings of Legacy Bridger. These Legacy Bridger Series B Preferred shares accrued interest at 17.5% annually, compounded quarterly. If not redeemed on or prior to March 31, 2022, the Legacy Bridger Series B preferred shares would have accrued interest at 21.5% annually, compounded quarterly. As the shares of Legacy Bridger Series B Preferred shares were mandatorily redeemable at a specified date, the security was classified as a liability in the Consolidated Balance Sheets. On April 25, 2022, Legacy Bridger used a portion of the proceeds from the issuance of the Legacy Bridger Series C Preferred shares to redeem all 60,000,000 of Legacy Bridger’s outstanding Legacy Bridger Series B Preferred shares for $70.0 million, inclusive of $10.0 million in accrued interest. There were no Legacy Bridger Series B Preferred Shares outstanding as of December 31, 2023 or December 31, 2022. Legacy Bridger Series A Preferred Shares Legacy Bridger was authorized to issue 10,500,000 shares of Series A-1 and A-2 Preferred shares (the “Legacy Bridger Series A-1 and A-2 Preferred Shares”) with a par value of $0.001 share for $105.0 million. The Series A-1 and A-2 Preferred Shares ranked senior to Legacy Bridger’s common shares and Legacy Bridger Series C Preferred shares with respect to distribution of assets upon liquidation or certain triggering events, but do not participate in earnings of Legacy Bridger. The Legacy Bridger Series A-1 and A-2 Preferred Shares were voting and non-voting shares, respectively. On April 25, 2022, Legacy Bridger used the proceeds from the issuance of the Legacy Bridger Series C Preferred Shares to redeem 4,444,444 shares of the Legacy Bridger Series A-1 and A-2 Preferred shares for $100.0 million. The loss on redemption of $34.6 million was reflected as a reduction to Accumulated deficit on the Consolidated Balance Sheets. On April 25, 2022, Legacy Bridger and its investors included a new mandatory redemption provision requiring the Legacy Bridger Series A-1 and Series A-2 Preferred Shares to be redeemed on April 25, 2032. Due to the mandatory redemption provision, the Legacy Bridger Series A-1 and A-2 Preferred Shares were reclassified from mezzanine equity to liability. Legacy Bridger elected the fair value option to measure the modification of the Legacy Bridger Series A-1 and A-2 Preferred Shares, recording a value of $132.3 million at modification. The modification of the Legacy Bridger Series A-1 and A-2 Preferred Shares was accounted for as an extinguishment, with the change in fair value of $45.6 million recorded to Accumulated deficit on the Consolidated Balance Sheets with no gain or loss recorded to net loss. The loss on extinguishment was included in net loss attributable to common shareholders used to calculate net loss per share. The Legacy Bridger Series A-1 and A-2 Preferred Shares accrued interest on a liquidation preference defined as the combined capital contributions plus accrued preferred interest amounts at a rate of 12% per annum. The Legacy Bridger Series A-1 and A-2 Preferred Shares were redeemable upon certain triggering events outside of the control of Legacy Bridger in the event of board expansion and deemed liquidation. Failure to pay the Legacy Bridger Series A-1 and A-2 Preferred Shares interest amount on a timely basis would trigger a board expansion event that provided the holders of the Legacy Bridger Series A-1 and A-2 Preferred Shares the option to obtain control of Legacy Bridger’s board of directors and initiate a triggering event. The triggering events included the sale of Legacy Bridger or its subsidiaries representing more than 50% of Legacy Bridger’s voting stock or assets, a qualified IPO or a similar liquidity event. The Legacy Bridger Series A-1 and A-2 Preferred Shares were redeemable at any time at the option of Legacy Bridger at a redemption price equal to the greater of the product of the investment amount multiplied by 2.25 plus any indemnification amounts or aggregate liquidation preference. Legacy Bridger identified certain redemption features that would be required to be considered for bifurcation. Legacy Bridger elected the fair value option and as such, valued the host preferred shares and embedded features as one instrument.

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	NOTE 23 – EARNINGS (LOSS) PER SHARE (RESTATED) Earnings (loss) per share of Common Stock is calculated in accordance with ASC 260, Earnings per share (“ASC 260”) . Earnings (loss) per share – Basic is calculated by dividing net income (loss) attributable to Common Stockholders by the weighted-average shares of Common Stock outstanding. Earnings (loss) per share – Diluted is based on the weighted average number of shares of Common Stock used for the Earnings (loss) per share - Basic calculation, adjusted for the weighted-average number of common share equivalents outstanding for the period determined using the treasury stock method and if-converted method, as applicable. Earnings (loss) attributable to Common Stockholders – Basic and Loss attributable to Common Stockholders - Diluted are adjusted for the impact of changes in the fair value of the Public Warrants and Private Placement Warrants, to the extent they are dilutive.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The Company consolidates those entities in which it, through the existing owners, has control over significant operating, financial or investing decisions of the entity. All significant intercompany balances and transactions have been eliminated in consolidation.
Variable Interest Entities	Variable Interest Entities The Company follows ASC 810-10-15 guidance with respect to accounting for variable interest entities (“VIE”). These entities do not have sufficient equity at risk to finance their activities without additional subordinated financial support from other parties or whose equity investors lack any of the characteristics of a controlling financial interest. A variable interest is an investment or other interest that will absorb portions of a VIE’s expected losses or receive portions of its expected returns and are contractual, ownership or pecuniary in nature and that change with changes in the fair value of the entity’s net assets. A reporting entity is the primary beneficiary of a VIE and must consolidate it when that party has a variable interest, or combination of variable interests, that provide it with a controlling financial interest. A party is deemed to have a controlling financial interest if it meets both of the power and loss/benefits criteria. The power criterion is the ability to direct the activities of the VIE that most significantly impact its economic performance. The losses/benefits criterion is the obligation to absorb losses from, or right to receive benefits from, the VIE that could potentially be significant to the VIE. The VIE model requires an ongoing reconsideration of whether a reporting entity is the primary beneficiary of a VIE due to changes in the facts and circumstances. Northern Fire Management Services, LLC (“NFMS, LLC”): The Company assisted in designing and organizing NFMS, LLC with a business purpose of employing Canadian aviation professionals to provide services to the Company. A master services agreement exists between NFMS, LLC and the Company, Bridger Air Tanker, LLC, a wholly owned subsidiary of the Company, to transfer all annual expenses incurred to the Company in exchange for the Canadian employees to support the Company’s water scooper aircraft. NFMS, LLC is 50% owned by a Canadian citizen, and 50% owned by Bridger Aerospace Group, LLC (“BAG, LLC”). NFMS, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s responsibility for all decisions related to NFMS, LLC’s expenditures. Accordingly, NFMS, LLC has been consolidated by the Company for the years ended December 31, 2023 and 2022 and all intercompany expenses associated with NFMS, LLC and its service agreement have been eliminated in consolidation. For the years ended December 31, 2023 and 2022, NFMS, LLC’s assets and liabilities were immaterial to the Company’s financial statements. Mountain Air, LLC (“MA, LLC”): As of November 7, 2022, MA, LLC is a wholly-owned subsidiary of Bridger. Prior to MA, LLC becoming a wholly-owned subsidiary of the Company, MA, LLC was owned 50% by Timothy Sheehy, the Chief Executive Officer and a director of Bridger, and 50% by an entity affiliated with Matthew Sheehy, a director of Bridger. MA, LLC is a Federal Aviation Administration (“FAA”) part 135 certificate holder and is designed to hold aerial firefighting contracts. Bridger Aviation Services, LLC (“Bridger Aviation”), a wholly-owned subsidiary of Bridger, was a party to a certain Management Services Agreement (the “Aviation Agreement”), dated April 13, 2018, with MA, LLC. Pursuant to the Aviation Agreement, Bridger Aviation leased certain aircraft to MA, LLC. MA, LLC operated the aircraft and paid Bridger Aviation a fee equal to 99% of all revenue it received from the use and deployment of Bridger Aviation’s aircraft. MA, LLC was obligated to operate and maintain the aircraft in accordance with applicable FAA standards. MA, LLC was determined to be a VIE primarily due to the entity’s lack of sufficient equity investment at risk and the Company was determined to be the primary beneficiary of the VIE primarily attributable to the Company’s substantial control. Accordingly, the Company consolidated MA, LLC for the periods prior to November 7, 2022 and all intercompany expenses associated with MA, LLC and its Aviation Agreement were eliminated in consolidation. On November 17, 2023, we entered into a series of agreements designed to facilitate the purchase and return to service of four Canadair CL-215T Amphibious Aircraft (the “Spanish Scoopers”) originally awarded to our wholly-owned subsidiary, Bridger Aerospace Europe, S.L.U. (“BAE”), in September 2023 via a public tender process from the Government of Spain for €40.3 million. Under the terms of the agreements, we agreed to sell the entire outstanding equity interest in BAE to MAB and purchase $4.0 million of non-voting Class B units of MAB. We also entered into a services agreement with MAB whereby we will manage the return to service upgrades of the Spanish Scoopers through our wholly-owned Spanish subsidiary, Albacete Aero, S.L., while they are owned and funded by MAB. The service agreement also provides that we have the right, but not the obligation, to acquire each Spanish Scooper as it is ready to be contracted and returned to service. The Company assessed both MAB and BAE for variable interest entity accounting under ASC 810-10-15 and determined that MAB is a voting interest entity and BAE is a variable interest entity. However, neither entity is consolidated in the consolidated financial statements as the Company does not have a controlling financial interest in MAB and the Company is not the primary beneficiary of BAE. Accordingly, neither of these entities have been consolidated in the consolidated financial statements of the Company for the year ended December 31, 2023. Refer to “Note 17 – Commitments and Contingencies” included in this Annual Report on Form 10-K for additional details.
Seasonality	Seasonality The Company’s business is generally seasonal, with a significant portion of total revenue occurring during the second and third quarters of the fiscal year due to the North American fire season. However, the weather dependency and seasonal fluctuation in the need to fight wildfires based upon location and the varying intensity of the fire season may lead our operating results to fluctuate significantly from quarter to quarter and year to year.
Use of Estimates	Use of Estimates
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash and all highly liquid, readily convertible investments with a maturity of three months or less. Cash equivalents are placed primarily in time deposits and money market funds due in three months or less. The Company’s subsidiaries generally maintain cash account balances sufficient to meet their short-term working capital requirements and periodically remit funds to the parent company to pay intercompany lease, maintenance and other charges. Substantially all of the Company’s cash is concentrated in a few financial institutions. At times, deposits in these institutions exceed the federally insured limits.
Restricted Cash	Restricted Cash
Investments in Marketable Securities	Investments in Marketable Securities Investments in debt securities are classified as available-for-sale and are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income. Gains and losses are recognized when realized. Unrealized losses are evaluated for impairment to determine if the impairment is credit related. An other-than-temporary credit impairment would be recognized as an adjustment to income. Gains and losses are determined using the first-in first-out method. Investments in marketable securities are classified as current assets with short-term maturities of less than one year.
Accounts and Notes Receivable	Accounts and Note Receivable Accounts receivable consist of amounts due from our customers. The Company maintains an allowance for doubtful accounts equal to the estimated losses expected to be incurred based upon a review of the outstanding accounts receivable, historical collection information and existing economic conditions. For the years ended December 31, 2023 and 2022, the Company did not record any bad debt expense as accounts receivable have historically been collected in accordance with the policy and there is no history of write-offs.
Aircraft Support Parts	Aircraft Support Parts Aircraft support parts consist of repairables and expendables that are used for servicing aircraft and support parts for universal application amongst the aviation fleet. Aircraft support parts are tracked by serial number and capitalized at cost in the Consolidated Balance Sheets and expensed in the Consolidated Statements of Operations when used in operations.
Property, Plant and Equipment, net	Property, Plant and Equipment, net Property, plant and equipment are recorded at cost when acquired. Except for aircraft, engines and rotable parts, depreciation is computed on the straight-line basis over the estimated useful life of property, plant and equipment and is recorded in Cost of revenues and Selling, general and administrative expense in the Consolidated Statements of Operations. Depreciation for aircraft, engines and rotable parts is recorded over the estimated useful life based on flight hours. The table below summarizes depreciable lives by asset category: Estimated Useful Life Aircraft, engines and rotable parts 1,500 – 6,000 flight hours Vehicles and equipment 3 – 5 years Buildings 40 years Aircraft undergo maintenance activities including routine repairs, inspections, part replacements and overhauls as required by regulatory authorities or manufacturer specifications. Costs of routine maintenance of aircraft are expensed as incurred as Cost of revenues in the Consolidated Statements of Operations. Costs that increase the value of the aircraft are capitalized as Property, plant and equipment, net in the Consolidated Balance Sheets and are depreciated over the asset’s useful life. Upon retirement or sale, the property, plant and equipment disposed of and the related accumulated depreciation are removed from the Consolidated Balance Sheets and any resulting gain or loss is recorded as Selling, general and administrative expense in the Consolidated Statements of Operations. Interest on long-term debt for the development or manufacturing of Company assets is capitalized to the asset until the asset enters production or use, and thereafter all interest is charged to expense as incurred.
Business Combinations	Business Combinations The Company records tangible and intangible assets acquired and liabilities assumed in business combinations under the acquisition method of accounting in accordance with ASC 805, Business Combinations . Under the acquisition method of accounting, amounts paid for the acquisition are allocated to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition inclusive of identifiable intangible assets. Acquisition consideration includes contingent consideration with payment terms based on the achievement of certain targets of the acquired business. The estimated fair value of identifiable assets and liabilities, including intangibles, are based on valuations that use information and assumptions available to management. The Company allocates any excess purchase price over the fair value of the tangible and identifiable intangible assets acquired and liabilities assumed to goodwill. Significant management judgments and assumptions are required in determining the fair value of assets acquired and liabilities assumed, particularly acquired intangible assets, including estimated useful lives. The valuation of purchased intangible assets is based upon estimates of the future performance and discounted cash flows of the acquired business. Each asset acquired or liability assumed is measured at estimated fair value from the perspective of a market participant. Contingent consideration represents an obligation of the acquirer to transfer additional assets or equity interests to the seller if future events occur or conditions are met, is recognized when probable and reasonably estimable. Contingent consideration recognized is included in the initial cost of the assets acquired and recorded in Accrued expenses and other current liabilities and Long-term accrued expenses and other noncurrent liabilities in the Consolidated Balance Sheets. Subsequent changes in the estimated fair value of contingent consideration are recognized as Selling, general and administrative expenses in the Consolidated Statements of Operations.
Intangible Assets	Intangible Assets Intangible assets consist of finite-lived intangible assets acquired through the Company’s historical business combinations and software developed for internal-use. In accordance with ASC Topic 350-40, Software - Internal-Use Software , the Company capitalizes certain direct costs of developing internal-use software that are incurred in the application development stage, when developing or obtaining software for internal use. Once the internal use software is ready for its intended use, it is amortized on a straight-line basis over its useful life. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Acquired intangible assets are initially recorded at fair value and subsequently amortized over their useful lives using the straight-line method, which reflects the pattern of benefit, and assumes no residual value. Intangible assets with definite lives are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. The remaining estimated useful lives of definite-lived intangible assets are routinely reviewed and, if the estimate is revised, the remaining unamortized balance is amortized over the revised estimated useful life.
Goodwill	Goodwill Goodwill represents the excess of purchase price over fair value of the net assets acquired in an acquisition. Refer to “Note 11 – Goodwill and Intangible Assets, Net” included in this Annual Report on Form 10-K. Beginning in 2023, the Company assesses goodwill for impairment as of October 1 annually or more frequently upon an indicator of impairment. Prior to 2023, the Company assessed goodwill for impairment as of December 31 annually or more frequently upon an indicator of impairment. The change to an October 1 annual goodwill impairment assessment date was made to ensure the completion of the Company’s assessment prior to the end of its annual reporting period, thereby aligning impairment testing procedures with its year-end financial reporting. Goodwill is tested for impairment at the reporting unit level using a fair value approach. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, based on a review of qualitative factors, it is more likely than not that the fair value of a reporting unit is less than its carrying value the Company compares the fair value of a reporting unit with its carrying amount. The Company determines the fair value of a reporting unit by estimating the present value of expected future cash flows, discounted by the applicable discount rate. If the carrying value exceeds the fair value, the Company measures the amount of impairment loss, if any, by comparing the implied fair value of the reporting unit goodwill with its carrying amount. No impairment charges have been required.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of the asset exceeds its estimated undiscounted net cash flow, excluding interest, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds its fair value. Investments accounted for under the equity method are recorded based upon the amount of the Company’s investment and are adjusted each period for the Company’s share of the investee’s income or loss. Investments are reviewed periodically for changes in circumstances or the occurrence of events that suggest an other-than-temporary event where the investment may not be recoverable.
Cost Method Investments	Cost Method Investments The Company holds equity securities without a readily determinable fair value, which are only adjusted for observable price changes in orderly transactions for the same or similar equity securities or any impairment. As of December 31, 2023 and 2022, the Company had $5.0 million and $1.0 million of cost method investments included in Other noncurrent assets in the Consolidated Balance Sheets, respectively.
Deferred Offerings Costs	Deferred Offering Costs
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs consist of expenditures associated with obtaining debt financing, principally legal and bank commitment fees. Such costs are deferred and amortized over the term of the related credit arrangements using a method that approximates the effective interest method. Debt issuance costs are included in the Consolidated Balance Sheets as a direct deduction from the carrying amount of long-term debt and are included in Interest expense in the Consolidated Statements of Operations. The payment of debt issuance costs is recorded under financing activities in the Consolidated Statements of Cash Flows.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company follows guidance in ASC 820, Fair Value Measurement (“ASC 820”), where fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are determined within a framework that establishes a three-tier hierarchy which maximizes the use of observable market data and minimizes the use of unobservable inputs to establish a classification of fair value measurements for disclosure purposes. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the information available. ASC 820 classifies the inputs used to measure these fair values into the following hierarchy: Level 1 — Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2 — Observable inputs and quoted prices in active markets for similar assets and liabilities. Level 3 — Unobservable inputs and models that are supported by little or no market activity. In all cases, the level in the fair value hierarchy within which the fair value measurement in its entirety has been determined based on the lowest level of input that is significant to the fair value measurement.
Revenue Recognition	Revenue Recognition The Company charges daily and hourly rates depending upon the type of firefighting service rendered and under which contract the services are performed. These services are primarily split into flight revenue and standby revenue. Flight revenue is earned primarily at an hourly rate when the engines of the aircraft are started and stopped upon request of the customer, tracked via flight logs for Super Scoopers or a Hobbs meter for other aircraft. Standby revenue is earned primarily as a daily rate when aircraft are available for use at a fire base, awaiting request from the customer for flight deployment. The Company enters into short, medium and long-term contracts with customers, primarily with government agencies during the firefighting season, to deploy aerial fire management assets. Revenue is recognized when performance obligations under the terms of a contract with our customers are satisfied and payment is typically due within 30 days of invoicing. Invoicing occurs as the services are rendered and includes the use of the aircraft, pilot and field maintenance personnel to support the contract. Contracts are based on either a Call-When-Needed (“CWN”) or Exclusive Use (“EU”) basis. Rates established are generally more competitive based on the security of the revenue from the contract (i.e., an EU versus only on an as-needed basis in CWN). These rates are delineated by the type of service, generally flight time or time available for deployment. Once an aircraft is deployed on a contract the fees are earned at these rates, the aircraft cannot be obligated to another customer. Contracts have no financing components and consideration is at pre-determined rates. No variable considerations are constrained within the contracts. The transaction prices are allocated on the service performed and tracked real-time by each operator in a duty log. On at least a monthly basis, the services performed and rates are validated by each customer. Acceptance by the customer is evidenced by their funded task order or accepted invoice. The Company has not incurred incremental costs for obtaining contracts with customers. In addition, the Company evaluates whether or not it should capitalize the costs of fulfilling a contract. Such costs would be capitalized when they are not within the scope of other standards and: (1) are directly related to a contract; (2) generate or enhance resources that will be used to satisfy performance obligations; and (3) are expected to be recovered. The Company has elected to use the practical expedient detailed in ASC 340-40, Other Assets and Deferred Costs-Contracts with Customers , to expense any costs to fulfill a contract as they are incurred when the amortization period would be one year or less. Contract assets are classified as a receivable when the reporting entity’s right to consideration is unconditional, which is when payment is due only upon the passage of time. As the Company invoices customers for performance obligations that have been satisfied, at which point payment is unconditional, contracts do not typically give rise to contract assets. Contract liabilities are recorded when cash payments are received or due in advance of performance. Payment terms vary by customer and type of revenue contract. The Company generally expects that the period of time between payment and transfer of promised goods or services will be less than one year. In such instances, the Company has elected the practical expedient to not evaluate whether a significant financing component exists. As permitted under the practical expedient available under ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”), the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, and (ii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. Other revenue consists of leasing revenues for facilities as well as external repair work performed on customer aircraft.
Income Taxes	Income Taxes For periods prior to the Business Combination, Bridger Aerospace Group Holdings, LLC is a partnership for federal income tax purposes. Consequently, federal income taxes are not payable or provided for by Legacy Bridger. Members are taxed individually on their pro rata ownership share of the Legacy Bridger’s earnings. Legacy Bridger’s net income or loss is allocated among the members in accordance with the Company’s operating agreement. Subsequent to the Business Combination, Bridger Aerospace Group Holdings, Inc. became the successor of Legacy Bridger as discussed in “ Note 1 – Organization and Basis of Presentation .” Bridger is subject to U.S. federal income taxes, in addition to state and local income taxes, with respect to net taxable income or loss and any related tax credits of the Company. Bridger is also subject to taxes in foreign jurisdictions in which it operates. The Company provides for income taxes and the related accounts under the asset and liability method. Income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. The Company is subject to income taxes predominantly in the U.S. These tax laws are often complex and may be subject to different interpretations. Deferred income taxes arise from temporary differences between the financial statement carrying amount and the tax basis of assets and liabilities and are measured using the enacted tax rates expected to be in effect during the year in which the basis difference reverses. In evaluating the ability to recover its deferred tax assets within the jurisdiction from which they arise, the Company considers all available positive and negative evidence. If based upon all available positive and negative evidence, it is more likely than not that the deferred tax assets will not be realized, a valuation allowance is established. The valuation allowance may be reversed in a subsequent reporting period if Bridger determines that it is more likely than not that all or part of the deferred tax asset will become realizable.
Segment Reporting	Segment Reporting Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the Company’s CODM. The Company manages its operations as a single segment for purposes of assessing performance, making operating decisions and allocating resources. This one operating and reporting segment primarily focuses on aerial firefighting.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times may exceed the Federal Depository Insurance Coverage of $250,000. During the years ended December 31, 2023 and 2022, the Company did not experience losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.
Hedging Transactions and Derivative Financial Instruments	Hedging Transactions and Derivative Financial Instruments The Company is directly and indirectly affected by changes in certain market conditions. These changes in market conditions may adversely impact the Company’s financial performance and are referred to as “market risks.” The Company, when deemed appropriate, uses derivatives as a risk management tool to mitigate the potential impact of certain market risks. The Company manages interest rate risk through the use of derivative instruments, such as swap agreements. A swap agreement is a contract between two parties to exchange cash flows based on specified underlying notional amounts, assets and/or indices. The Company does not enter into derivative financial instruments for trading purposes. The accounting for gains and losses that result from changes in the fair values of derivative instruments depends on whether the derivatives have been designated and qualify as hedging instruments and the type of hedging relationships. The changes in fair values of derivatives that have been designated and qualify as cash flow hedges are recorded in Accumulated other comprehensive income and are reclassified into the line item in the Consolidated Statements of Comprehensive Loss in which the hedged items are recorded in the same period the hedged items affect earnings. The Company formally assesses whether the financial instruments used in hedging transactions are effective at offsetting changes in either the fair values or cash flows of the related underlying exposures. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized into earnings. The fair value is based on prevailing market data and using standard valuation models based on reasonable estimates about future relevant market conditions. Refer to “ Note 16 – Long-Term Debt ” included in this Annual Report on Form 10-K. The notional amounts of the derivative financial instruments do not necessarily represent amounts exchanged by the parties and, therefore, are not a direct measure of the Company’s exposure to the financial risks described above.
Earnings (Loss) Per Share	Earnings (Loss) Per Share Basic earnings per share is based on the weighted average number of shares of Common Stock outstanding during the period. Diluted earnings per share is based on the weighted average number of shares of Common Stock used for the basic earnings per share calculation, adjusted for the dilutive effect of restricted stock units (“RSUs”), Warrants, and Incentive Units, if any, using the “treasury stock” method, the Series A Preferred Stock that is convertible into shares of Common Stock, and the Sponsor Earnout Shares that will fully vest upon certain stock price metrics being achieved. In addition, earnings for diluted earnings per share is adjusted for the after-tax impact of changes to the fair value of the Warrants, to the extent they are dilutive. As noted above, the Company accounted for the Closing as a reverse recapitalization. Earnings per share calculations for all periods prior to the Closing have been retrospectively adjusted by the Exchange Ratio for the equivalent number of shares of Common Stock outstanding immediately after the Closing to effect the reverse recapitalization. Subsequent to the Closing, earnings per share is calculated based on the weighted average number of shares of Common Stock outstanding.
Commitments and Contingencies	Commitments and 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. Legal costs incurred in connection with loss contingencies are expensed as incurred.
Collaboration Agreements	Collaboration Agreements The Company analyzes its collaboration arrangement to assess if it is within the scope of ASC Topic 808, Collaborative Agreements (“ASC 808”) by determining whether such an arrangement involves joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. If the Company concluded that it has a customer relationship with its collaborator, the collaboration arrangement would be accounted for under ASC 606.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for its stock-based compensation in accordance with provisions of ASC 718, Compensation-Stock Compensation at the grant date fair value. Legacy Bridger granted Incentive Units which contain service and performance vesting conditions to select board members and an executive officer. Compensation cost for Incentive Units is measured at their grant-date fair value and is equal to the value of the Legacy Bridger’s Class D Common shares, which was estimated using an option pricing model. Compensation cost for service-based units is recognized over the requisite service period on a straight-line basis. For performance related units, expense is recognized when the performance related condition is considered probable. In connection with the Closing, the Company along with the Board established and approved and assumed the Bridger Aerospace Group Holdings, Inc. 2023 Omnibus Incentive Plan (the “Omnibus Plan”) which allowed the Company to grant RSUs to Bridger employees (the “Participants”). Upon satisfying the vesting conditions, each RSU provides the Participants the right to receive one share of Common Stock. The fair value of RSUs is determined based on the number of shares granted and the quoted market price of the Common Stock on the date of grant. Compensation cost for the RSUs is recognized as the performance condition of the Closing of the transaction was met and over the requisite service period based on the graded-vesting method. The Company accounts for forfeitures as they occur. Stock-based compensation is included in both Cost of revenues and Selling, general and administrative expense in the Consolidated Statements of Operations.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The amendments in this ASU replace the incurred loss model for recognition of credit losses with a methodology that reflects expected credit losses over the life of the loan and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. The Company adopted this standard on January 1, 2023. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment . This update modifies the concept of impairment from the condition that exists when the carrying amount of goodwill exceeds its implied fair value to the condition that exists when the carrying amount of a reporting unit exceeds its fair value. In order to reduce complexity, an entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. The Company adopted this standard on January 1, 2023. The adoption of this standard did not have a significant impact on the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative . This update modifies the disclosure or presentation requirements of a variety of topics in the codification. The effective date for each amendment will be the date on with the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective. Early adoption is prohibited. The Company is currently evaluating the impact of adopting the new accounting guidance on the Company’s consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . This update expands annual and interim reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This new guidance is effective for the Company for its fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company does not expect the adoption of this standard to have a material impact on the Company’s consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . This update enhances the transparency and decision usefulness of income tax disclosures to provide investors information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This new guidance is effective for the Company for its fiscal years beginning after December 15, 2024. The Company is currently evaluating the impact of adopting the new accounting guidance on the Company’s consolidated financial statements.
