2. Summary of Significant Accounting Policies

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in these condensed consolidated financial statements.

Unaudited Interim Financial Information

The condensed consolidated financial statements as of March 31, 2025 are unaudited. These interim financial statements of NextNav have been prepared in accordance with U.S. General Accepted Accounting Principles (“GAAP”) and SEC instructions for interim financial information and should be read in conjunction with NextNav’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”), which the Company filed with the SEC on March 12, 2025.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and reflect, in management’s opinion, all adjustments of a normal, recurring nature that are necessary for the fair statement of the Company’s financial position as of March 31, 2025, results of operations for the three months ended March 31, 2025 and 2024, and changes in stockholders’ equity and cash flows for the three months ended March 31, 2025 and 2024, but are not necessarily indicative of the results expected for the full fiscal year or any other period.

There have been no changes to the Company’s significant accounting policies described in the 2024 Form 10-K that have had a material impact on these condensed consolidated financial statements and related notes.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period and accompanying notes. These estimates include those related to the useful lives and recoverability of long-lived and intangible assets, valuation of common stock warrants, derivative liability-conversion option, income taxes and equity-based compensation, among others. NextNav bases estimates on historical experience, anticipated results and various other assumptions, including assumptions of future events, it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, equity, revenue and expenses, that are not readily apparent from other sources. Actual results and outcomes could differ materially from these estimates and assumptions.

Cash and Cash Equivalents and Marketable Securities

Cash and cash equivalents include all cash in banks and highly liquid investments with an original maturity of three months or less when purchased. The combined account balances held on deposit at each institution typically exceed Federal Deposit Insurance Corporation (“FDIC”) insurance coverage and, as a result, there is a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company seeks to reduce this risk by maintaining such deposits with high quality financial institutions that management believes are creditworthy. Further, the Company seeks to minimize its exposure to banking risk by limiting the amount of uninsured deposits and investing its excess cash in U.S. government and government agency bonds, and money market funds.

The Company invests excess cash primarily in U.S. treasury bills and money market funds. The Company classifies all marketable securities that have stated maturities of three months or less from the date of purchase as cash equivalents, and those that have stated maturities of over three months as short-term investments on the Condensed Consolidated Balance Sheets. The Company determines the appropriate classification of investments in marketable securities at the time of purchase and reevaluates such designation at each balance sheet date. Marketable securities that are held for resale are classified as "trading securities" and are measured at fair value with the related gains and losses, including unrealized, recognized in interest expense, net. Marketable securities not classified as held to maturity or as trading securities are classified as "available-for-sale securities" and the fair value option (“FVO”) was elected, for which related gains and losses, including unrealized gains and losses and interest, are recognized in interest expense, net. The FVO election allows the Company to account for the marketable securities at fair value, which is consistent with the manner in which the instruments are managed. For the three months ended March 31, 2025 and 2024, the Company recorded gains of $333 thousand and $367 thousand, respectively, from fair value changes related to the FVO available-for-sale debt securities, which were recorded within interest expense, net, in the Condensed Consolidated Statements of Comprehensive Loss.

Revenue

The following table presents the Company’s revenue disaggregated by category and source:

	Three Months Ended March 31,
	2025		2024
	(in thousands)
Commercial	$	932	$	1,041
Government contracts		607		5
Total revenue	$	1,539	$	1,046

Contract Balances

Accounts receivable are billed and unbilled amounts related to the Company’s rights to consideration as performance obligations are satisfied when the rights to payment become unconditional but for the passage of time. As of March 31, 2025 and December 31, 2024, the Company’s accounts receivable balances were comprised of $1.6 million and $3.3 million, respectively. The Company assesses collectability by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when the Company identifies specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status and makes judgments about the creditworthiness of customers based on ongoing credit evaluations. The Company also considers customer-specific information, current market conditions, and reasonable and supportable forecasts of future economic condition. An allowance for credit losses for accounts receivable is recorded as an offset to accounts receivable, and changes in such are classified as selling, general and administrative expense in the Consolidated Statements of Comprehensive Loss. As of both March 31, 2025 and December 31, 2024, all accounts receivable balances were current and no allowance for credit losses were recorded.

Contract liabilities relate to amounts billed in advance, or advance consideration received from customers, for which transfer of control of the good or service occurs at a later point in time. As of March 31, 2025 and December 31, 2024, the Company’s contract liabilities were $310 thousand and $288 thousand, respectively, and are recorded in deferred revenue in the Condensed Consolidated Balance Sheets.

Equity-Based Compensation

Measurement of equity-based compensation with employees is based on the estimated grant date fair value of the equity instruments issued. The fair value of stock options is determined using the Black-Scholes option pricing model. The fair value of restricted awards is based on the closing price of NextNav’s common stock on the date of grant. NextNav recognizes equity-based compensation on a straight-line basis over the requisite service period of the grant, which is generally equal to the vesting period. NextNav accounts for forfeitures as they occur.

The following details the amount of stock-based compensation included in cost of goods sold, research and development, and selling, general and administrative expenses:

	Three Months Ended March 31,
	2025		2024
	(in thousands)
Cost of goods sold	$	237	$	150
Research and development		1,043		1,431
Selling, general and administrative		3,044		2,663
Total stock-based compensation expense	$	4,324	$	4,244

Basic and Diluted Net Loss per Share

Basic loss per share (“EPS”) excludes dilution for common share equivalents and is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS is based on the weighted-average number of shares of common stock outstanding during each period, adjusted for the effect of dilutive common share equivalents.

Restricted shares are included in the computation of basic EPS as they vest and are included in diluted EPS, to the extent they are dilutive, determined using the treasury stock method. Outstanding options and warrants are included in the computation of diluted EPS, to the extent they are dilutive, determined using the treasury stock method.

The determination of the diluted weighted average shares is included in the following calculation of EPS:

	Three Months Ended March 31,
	2025			2024

Equity Method Investment

The Company applies the equity method of accounting to investments when it has significant influence, but not controlling interest, in the investee. Judgment regarding the level of influence over each equity method investment includes considering key factors such as ownership interest, representation on the board of directors, participation in policy-making decisions and material intercompany transactions.

The initial carrying value of equity method investment is based on the amount paid to purchase the interest in the investee entity. Subsequently, the investment is increased or decreased by the Company’s proportionate share in the investee’s earnings or losses and decreased by cash distributions from the investee. The Company eliminates from its financial results all significant intercompany transactions to the extent of its ownership interest, including the intercompany portion of transactions with equity method investee. The Company’s share of the investee’s income or loss is recorded on a one quarter lag.

The Company evaluates equity method investment for impairment based upon a comparison of the fair value of the equity method investment to its carrying value, when impairment indicators exist. If the Company determines a decline in the fair value of an equity method investment below its carrying value is other-than-temporary, an impairment is recorded.

Leases

NextNav leases office spaces under non-cancellable leases as well as site leases for towers and shelters under operating leases related to its network. Site leases are entered into throughout the United States under which NextNav receives the rights to install equipment used to transmit its services over its licensed spectrum. The Company, at the inception of the contract, determines whether a contract is or contains a lease based on assessment of the terms and conditions of the contract. The Company classifies leases with contractual terms longer than twelve months as either operating or finance. The Company has elected not to recognize lease assets and liabilities for its short-term leases, which are defined as leases with an initial term of twelve months or less.

The Company’s leases may include options to extend or terminate the lease. The option to renew may be automatic, at the option of NextNav or mutually agreed to between the landlord and NextNav. Lease terms include the non-cancellable term and periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

The Company’s lease agreements generally contain lease and non-lease components. Payments under the lease arrangements are primarily fixed. Non-lease components primarily include payments for utilities and maintenance. The Company combines fixed payments for non-lease components with lease payments and accounts for them together as a single lease component which increases the amount of the Company’s lease assets and liabilities. Certain lease agreements contain variable payments, which are expensed as incurred and not included in the lease assets and liabilities. These amounts include payments for common area maintenance.

Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Lease assets are reduced by landlord incentives, plus any direct costs from executing the leases or lease prepayments reclassified from “Other current assets” upon lease commencement. Operating lease expense is recognized on a straight-line basis over the lease term. Monthly rent expense includes any site related utility payments or other fees such as administrative or up-front fees contained in the lease agreements that are determinable upon execution of the lease agreement.

Acquired finite-lived intangible assets

Acquired finite-lived intangible assets primarily includes proprietary technology and software. See Note 4 — Intangibles.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired in a business combination. Goodwill is not amortized but is tested for impairment annually in the fourth quarter or more frequently if events or changes in circumstances indicate that the asset may be impaired. The Company operates as one reporting unit. When testing goodwill for impairment, the Company may first perform an optional qualitative assessment. If the Company determines it is not more likely than not the reporting unit’s fair value is less than its carrying value, then no further analysis is necessary. If the Company determines that it is more likely than not that the fair value of its reporting unit is less than its carrying amount, then the quantitative impairment test will be performed. Under the quantitative impairment test, if the carrying amount of the Company’s reporting unit exceeds its fair value, the Company will recognize an impairment loss in an amount equal to that excess but limited to the total amount of goodwill. No goodwill impairment was recorded for the three months ended March 31, 2025 and for the year ended December 31, 2024. The following summarizes the Company's goodwill activities:

	Three Months Ended March 31,
	2025		2024
	(in thousands)
Beginning Balance	$	16,966	$	17,977
Changes in foreign exchange rates		675		(396	)
Ending Balance	$	17,641	$	17,581

Acquisitions

The Company accounts for its acquisitions using the acquisition method of accounting. The purchase price is attributed to the fair value of the assets acquired and liabilities assumed. Transaction costs directly attributable to the acquisition are expensed as incurred. Identifiable assets and liabilities acquired or assumed are measured separately at their fair values as of the acquisition date. The excess of the purchase price of acquisition over the fair value of the identifiable net assets of the acquiree is recorded as goodwill. The results of businesses acquired are included in the Company’s consolidated financial statements from the date of acquisition.

When the Company issues stock-based or cash awards to an acquired company’s shareholders, the Company evaluates whether the awards are consideration or compensation for post-acquisition services. The evaluation includes, among other things, whether the vesting of the awards is contingent on the continued employment of the acquired company’s stockholders beyond the acquisition date. If continued employment is required for vesting, the awards are treated as compensation for post-acquisition services and recognized as expense over the requisite service period.

Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates, including the selection of valuation methodologies, estimates of future revenue and cash flows, discount rates, and selection of comparable companies. The estimates and assumptions used to determine the fair values and useful lives of identified intangible assets could change due to numerous factors, including market conditions, technological developments, economic conditions, and competition. During the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the fair value of these tangible and intangible assets acquired and liabilities assumed, with the corresponding offset to goodwill. In addition, uncertain tax positions, tax-related valuation allowances and pre-acquisition contingencies are initially recorded as of the acquisition date. The Company continues to collect information and reevaluates these estimates and assumptions quarterly and records any adjustments to the Company’s preliminary estimates to goodwill provided that the Company is within the measurement period. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the Company’s consolidated statement of operations. In connection with the determination of fair values, the Company may engage a third-party valuation specialist to assist with the valuation of intangible and certain tangible assets acquired and certain assumed obligations.

Long term debt

The carrying value of long-term debt in the Company’s Condensed Consolidated Balance Sheets generally consists of principal amount of debt, net of debt discounts. The Company evaluates its debt agreements to determine whether debt contains embedded features requiring bifurcation from the debt host in accordance with Accounting Standards Codification 815, Derivatives and Hedging ("ASC 815"). If an embedded feature requires bifurcation from its debt host, the Company will account for it as a derivative at fair value. If a hybrid instrument has multiple embedded derivatives requiring bifurcation, the Company will bifurcate a single compound derivative. The Company uses valuation models to estimate the fair value of the bifurcated embedded derivatives. Debt discounts recognized as a result of allocating proceeds to bifurcated embedded derivatives as well as accounting for direct debt issuance costs are amortized to interest expense using the effective interest method.

The fair value of bifurcated derivatives is presented in the same line item as debt in the Company's Condensed Consolidated Balance Sheets.

Unamortized debt discounts are written off and included in the Company’s gain or loss calculations to the extent the Company extinguishes debt prior to the original maturity.

Foreign Currency Translation

The functional currency of NextNav’s foreign subsidiaries is generally the local currency. Assets and liabilities are translated into U.S. dollars at the exchange rate in effect at the Condensed Consolidated Balance Sheet date. Operating accounts are translated at an average rate of exchange for the respective accounting periods. Translation adjustments resulting from the process of translating foreign currency financial statements into U.S. dollars are reported as a component of accumulated other comprehensive loss. Transaction gains and losses reflected in the functional currencies are charged to income or expense at the time of the transaction.

Net transaction gains (losses) from foreign currency contracts recorded in the Condensed Consolidated Statements of Comprehensive Loss were immaterial for the three months ended March 31, 2025 and 2024. The only component of other comprehensive loss is currency translation adjustments for all periods presented. No income tax expense was allocated to the currency translation adjustments.

Segments

NextNav operates as one operating segment. NextNav’s chief operating decision maker (“CODM”) is its Chief Executive Officer, who reviews financial information presented on an entity-wide basis for purposes of making operating decisions, assessing financial performance and allocating resources.

Recent Accounting Developments Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 is effective for the Company's annual periods beginning January 1, 2026 with early adoption permitted, and requires the Company to disclose additional information on the rate reconciliation and income taxes paid. The Company has not yet adopted ASU 2023-09 and is currently evaluating the potential effect that the updated standard will have on the financial statement disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40)— Disaggregation of Income Statement Expenses (“ASU 2024-03”), which requires disclosure in the notes to the financial statements of specified information about certain costs and expenses. ASU 2024-03 is effective for the Company's annual periods beginning January 1, 2027, on a prospective basis, with early adoption and retrospective application permitted. The Company has not yet adopted ASU 2024-03 and is currently evaluating the potential effect of the adoption on its consolidated financial statements.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s consolidated financial statements.
