Organization, Consolidation and Presentation of Financial Statements [Abstract]  
ORGANIZATION & BUSINESS ORGANIZATION & BUSINESS
Republic Airways Holdings Inc. (the “Company” or the “Parent”) is a Delaware holding company conducting substantially all of its operations through its wholly-owned regional air carrier subsidiaries, Republic Airways Inc. (“Republic Airways”) and Mesa Airlines, Inc. (“Mesa” or “Mesa Airlines”). The Company regularly provides scheduled passenger service on approximately 1,300 flights daily to approximately 130 cities in the United States, Canada, Mexico, and the Caribbean operating under the American Eagle, Delta Connection, and United Express brands through the Company’s partnerships with American Airlines, Inc. (“American Airlines”), Delta Air Lines, Inc. (“Delta Air Lines”), and United Airlines, Inc. (“United Airlines”) (collectively, our “Partners” or “Partner Airlines”) under fixed-fee capacity purchase agreements (“CPA,” or collectively, our “CPAs”). The Company’s operating subsidiaries, Republic Airways and Mesa Airlines, exclusively operate the Embraer E170/175 family of aircraft among our Partner Airlines’ hub and focus cities.
On November 25, 2025, the Company and Mesa Air Group, Inc. (“Mesa Parent”), former parent company of Mesa Airlines, completed the Merger of Republic Airways Holdings Inc. and Mesa Air Group, Inc., whereby the Company merged with and into Mesa Air Group, Inc. (the “Merger”). The legal entity Mesa Air Group, Inc. continued as the surviving corporation; however, upon completion of the Merger, the legal entity was renamed Republic Airways Holdings Inc. The Company, on a pre-Merger basis, is referred to as “Legacy Republic.” The Company includes the operations of Legacy Republic and, beginning on November 25, 2025, also includes the operations, financial position, and cash flows of the former entity Mesa Air Group, Inc. and its wholly-owned subsidiaries. See Note 3, Merger with Mesa Air Group, Inc.
The Company also operates its Leadership In Flight Training Academy (“LIFT Academy”) with a mission to attract a new generation of aviation professionals to commercial aviation by providing superior flight training, while addressing the economic, regulatory, and structural barriers to entry to the aviation industry by offering its graduates a defined career pathway to First Officer with Republic Airways. The Company also operates Bridge Air with a dedication to helping aviation professionals achieve their dream of becoming a commercial airline pilot as quickly, safely, and inexpensively as possible.
Aircraft under operation for each of our Partner Airlines as of December 31, 2025 are as follows:
Aircraft (1) (2)
American Airlines
Delta Air Lines
United Airlines
Total Aircraft
E170
1311428
E175
7946122247
Total9257126275
(1)Represents the minimum operational fleet out of a total of 280 aircraft as of December 31, 2025, excluding five spare aircraft.
(2)Excludes 31 aircraft leased to American Airlines as of December 31, 2025.
Capacity purchase agreements—Each of our fixed-fee CPAs are structured so that revenues are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred in addition to overall aircraft in service and aircraft per day fees, payable on a monthly basis; and (ii) a premium amount, which is earned by maintaining a minimum aircraft utilization and exemplary operating results. We additionally receive reimbursement from our Partner Airlines for direct expenses incurred, such as qualifying maintenance activities, insurance, and property taxes.
Certain charges such as fuel and landing fees are generally paid directly by the Partner Airlines, although the charges were incurred by the Company in ongoing operations. The Company refers to these charges as “Partner direct charges.” Pass-through charges are primarily recorded to revenues and the corresponding operating expense on a gross basis. Pass-through charges recorded on a net basis are not material.
Pursuant to our fixed-fee capacity purchase agreements, the Company provides passenger service on behalf of American Airlines, Delta Air Lines, and United Airlines, authorizing us to use the Partner Airlines’ two-character flight designator codes (American Airlines—“AA,” Delta Air Lines—“DL,” and United Airlines—“UA”) to identify our flights and fares directly within each Partner’s reservation systems, and to outfit our interior and exterior aircraft livery with Partner Airlines’ colors, logos, and service marks, allowing for joint marketing of our flights by the operating regional air carrier and each of our Partner Airlines. Passenger tickets are issued by each of our Partner Airlines, who therefore bear the risk associated with fare competition and management of seat inventory. In addition, under the Company’s fixed-fee arrangements with American Airlines, Delta Air Lines, and United Airlines, passengers of the Company are eligible for participation in the Partner Airlines’ frequent flyer loyalty programs: AAdvantage®, SkyMiles®, and MileagePlus®, respectively. Support services such as reservations, ticketing, ground handling services, fuel procurement, commuter slot rights, and airport facilities are additionally provided by the Partner Airlines. Significant provisions to our CPAs, which are amended from time to time, are discussed in Note 5, Revenue Recognition.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of presentation—The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Republic Airways Holdings Inc. and its wholly-owned subsidiaries. Beginning November 25, 2025 and in conjunction with the Merger, the consolidated financial statements include the accounts of Mesa Air Group, Inc. and its wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. Certain prior year balances have been reclassified to conform to current year presentation, including additional captions for Other current assets — related party and Stock-based compensation expense on the accompanying financial statements. Also, see Note 4, Executive Separation and Merger-Related Items.
Use of estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the carrying amounts of assets and liabilities, reported amounts of revenues and expenses, and the related disclosures thereto as of and during the periods presented, which management reassesses and evaluates on an ongoing basis. Significant estimates include but are not limited to (i) revenue recognition, (ii) estimated useful lives and residual values of aircraft and equipment, (iii) provision for income taxes, (iv) estimated fair value assumptions supporting the fair value of certain investments, put options, and warrants, and (v) provisional estimated fair value assumptions used to determine the fair values of assets acquired and liabilities assumed in the Merger in conjunction with the application of the acquisition method of accounting for business combinations under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations. See Note 3, Merger with Mesa Air Group, Inc. In addition, based on the nature of the CPA relationships, the Company estimates operating costs for certain reimbursable pass-through charges and records revenues based on these estimates. Actual results could materially differ from our initial estimates.
Cash, cash equivalents and restricted cash—Cash and cash equivalents consists of cash on-hand and short-term, highly liquid investments with maturities of three months or less when acquired. Substantially all of our cash on-hand is held with six financial institutions. Restricted cash primarily includes cash in escrow to secure letters of credit issued for workers’ compensation claim reserves, construction activities, student loan guarantees, and deposits with various airport authorities.
Investments—The Company holds investments in debt and equity securities, stock warrants and put options, and equity method investments. Investments classified as marketable securities relate primarily to U.S. Treasury securities and are recorded to marketable securities in the consolidated balance sheets. The Company designates securities as trading, available-for-sale, or held-to-maturity, as applicable, at the time of acquisition and are subsequently measured at fair value or amortized cost at each reporting date. All of the Company’s investments in marketable securities were held for trading purposes during the years ended December 31, 2025, 2024, and 2023, and as a result, realized and unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations, representing Level 1 fair value measurements as defined in FASB ASC 820, Fair Value Measurement.
Non-current investments are investments with maturities greater than 12 months, described below, or investments which management of the Company intends to hold for a period greater than 12 months. Non-current investments are subject to provisions of FASB ASC 321, Investments, and are recorded to other non-current assets in the consolidated balance sheets at their acquisition date fair value and subsequently measured to fair value at each reporting date. Non-current investments are Level 1 fair value measurements as defined in the FASB ASC 820, Fair Value Measurement, fair value hierarchy. Realized and unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations.
The Company is additionally a warrant holder for stock warrants issued to certain initial investors in conjunction with our strategic partnership with EVE Holdings Inc. (“EVE”) for the development of electric vertical takeoff and landing (“eVTOL”) aircraft, exercisable through May 2027. Also related to our strategic relationship with EVE, the Company holds a put option attached to shares held in EVE equity that is exercisable on demand through May 2032. Stock warrants and the put option are characterized as financial instruments and are initially recorded and subsequently measured to fair value at each reporting date. Such amounts are recorded to other non-current assets in the consolidated balance sheets. Unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations.
Equity method investments are initially measured at cost and subsequently adjusted for the Company’s proportionate share of income or loss of the investee and recorded to other non-current assets in the consolidated balance sheets in accordance with FASB ASC 323, Investments—Equity Method and Joint Ventures. The Company’s portion of income or loss generated by these investments are included as part of investment income and other, net in the consolidated statements of operations. The Company routinely monitors its investments for factors that may indicate a potential decline in value that is other than temporary.
The Company holds a 43.6% ownership interest in Hyannis Air Service Inc. d/b/a Cape Air and Nantucket Airlines (“Cape Air”). The investment is meant to foster a strategic workforce relationship between the participating airlines. Upon completion of flight training at LIFT Academy, certain graduates can acquire First Officer and Captain experience at Cape Air until they have met experience requirements to fly with the Company. The Cape Air investment is accounted for under the equity method of accounting. As of December 31, 2025 and 2024, the Company’s investment totaled $15.3 million and $15.0 million, respectively, and is included in other non-current assets in the consolidated balance sheets. During the years ended December 31, 2025, 2024, and 2023, the Company recognized $0.3 million of earnings, a $0.1 million loss, and a $3.8 million loss in Cape Air, respectively, recorded to investment income and other, net, in the consolidated statements of operations.
Fair value of financial instruments—The Company measures cash and cash equivalents, restricted cash, debt and equity securities, warrants, and put options at fair value on a recurring basis. Fair value, which is defined as an exit price related to the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, is measured using a combination of valuation practices as follows, as applicable:
Market approach—a valuation technique using prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities (or groups of assets and liabilities).
Income approach—valuation approach which converts future amounts to a single current (discounted) amount and is determined on the basis of the value indicated by current market expectations about those future amounts.
The Company classifies its fair value measurements based on the fair value hierarchy defined in ASC 820, Fair Value Measurement, which prioritizes the inputs used in determining fair value as follows:
Level 1    Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2    Quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3    Unobservable inputs for the asset or liability.
Inventories—Inventories consist of spare aircraft parts and supplies, which are charged to expense as consumed in the Company’s operations. Aircraft inventory is stated at weighted average cost at the lower of cost or its net realizable value. Inventory valuation adjustments are recorded to maintenance and repair expense in the consolidated statements of operations. The inventory valuation adjustments for the years ended December 31, 2025, 2024, and 2023 were $1.1 million, $2.2 million, and $0.8 million, respectively.
Assets held for sale—The Company classifies assets as held for sale when (i) management commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition, subject only to terms that are usual and customary for sales of such assets; (iii) an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated; (iv) the sale of the asset is probable, and transfer of the asset is expected to occur within one year, among other conditions. Assets designated as held for sale are recorded to other current assets in the consolidated balance sheets at the lower of their current carrying values or their fair market values, less costs to sell, beginning in the period in which the assets meet the criteria to be classified as held for sale. The account balance is not material.
Property and equipment—The Company records property and equipment at its historical cost, less accumulated depreciation, which is charged to expense on a straight-line basis over the estimated useful life of the related asset. Effective January 1, 2024, the Company adjusted the estimated useful life of certain aircraft, rotable spare parts, and engines from 22.0 to 26.0 years to more closely align with market data impacting our fleet usage pattern. The change in accounting estimate decreased depreciation and amortization expense by $50.5 million for the year ended December 31, 2024 on then-current fleet assets. Estimated useful lives and residual values for each asset class are as follows:
Asset Class
Current Useful

Management reviews asset groups for impairment when events and business circumstances indicate carrying values of assets may not be recoverable. In such circumstances, management evaluates undiscounted cash flows expected to be generated by the respective asset group in comparison to its carrying value. Impairment charges, if any, are measured based on the excess carrying value over estimated fair value of the asset group. No impairment charges were recognized during the years ended December 31, 2025, 2024, and 2023.
Goodwill—Goodwill represents the excess of consideration exchanged over the fair value of identifiable assets acquired and liabilities assumed in conjunction with a business combination. Goodwill is initially recognized to comply with ASC 805, Business Combinations. Goodwill is assigned to the relevant reporting unit and is reviewed at least annually on October 31, or more frequently, if conditions indicate the carrying value of goodwill may not be recoverable to comply with provisions of ASC 350, Intangibles – Goodwill and Other.
The changes in the carrying amount of goodwill for the years ended December 31, 2025, 2024, and 2023 are as follows:

The Company recorded no impairments during the years ended December 31, 2025, 2024, and 2023.
Manufacturer incentives—The Company’s aircraft and original equipment manufacturers periodically provide credits and rebates toward aircraft and equipment part purchases. Incentives associated with aircraft and equipment are applied as a reduction to the aircraft and equipment purchase price upon delivery, effectively reducing depreciation expense on a straight-line basis over aircraft and engine useful lives.
Income taxes—The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in future years in which those temporary differences are expected to be recovered or settled. The measurement of deferred tax assets is adjusted by a valuation allowance, if necessary, to recognize future tax benefits to the extent that it is more likely than not they will be realized based on available evidence. The Company establishes liabilities for uncertain positions taken or expected to be taken in income tax returns, using a more-likely-than-not recognition threshold. The Company utilizes the enacted tax rate of 21.0% for federal income tax purposes. See Note 11, Income Taxes.
Aircraft maintenance and repair—Aircraft maintenance and repair charges, including line maintenance, routine overnight maintenance, auxiliary power units, and airframe and engine overhaul are accounted for using the direct expense method.
In addition, the Company enters into long-term maintenance agreements that fix certain costs related to engines and other airframe components. Risks associated with these arrangements have been transferred to maintenance providers, and therefore, corresponding maintenance charges are recognized as power-by-the-hour contracts at a level rate per hour, subject to customary minimum utilization requirements. See Note 12, Commitments.
Mezzanine equity—During the year ended December 31, 2020, the Company adopted the 2020 Omnibus Incentive Plan in which restricted stock units (“RSUs”) were issued to members of the Board of Directors and key members of management. RSUs are conditionally redeemable upon the occurrence of events that are not solely within control of the issuer of the securities. As such, RSUs are classified as mezzanine (temporary) equity as to convey that these shares may not have a permanent equity classification. All of the Company’s RSUs classified as mezzanine equity were reclassified to common stock and additional paid-in-capital at consummation of the Merger. See Note 14, Mezzanine Equity and Capital Transactions.
Shareholders’ equity—Shareholders’ equity consists of preferred stock, par value $0.001, 500,000,000 shares authorized and no shares issued or outstanding as of December 31, 2025 and 2024; common stock, par value $0.001, 5,000,000,000 shares authorized, 45,713,286 shares and 38,993,300 shares issued and outstanding, respectively, as of December 31, 2025 and 2024. Additional paid-in capital consists of capital amounts contributed in excess of par value.
In conjunction with the Merger, Mesa Air Group, Inc. effectuated a 15-for-1 reverse stock split (the “Reverse Stock Split”). Further, in conjunction with the Merger closing, the Company received 38.9933 shares of common stock of legacy Mesa Air Group in exchange for and cancellation of each outstanding share of legacy Republic Airways common stock immediately prior to the Merger (the “Exchange”). Presentation of shareholders’ equity as of December 31, 2025 and 2024 retrospectively applies the Reverse Stock Split and the Exchange to consistently conform and to comply with the relevant provisions of ASC 505, Shareholders’ Equity.
The Company additionally holds an equity participating right of $2.3 million as of December 31, 2025 for the settlement of shares held in escrow for the final settlement of consideration exchanged in the Merger, which is recorded as a reduction to additional paid-in capital in the consolidated balance sheets. See Note 3, Merger with Mesa Air Group, Inc.
U.S. Treasury Warrants—In 2020 and 2021, in connection with the Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “CARES Act”) payroll support program (“PSP”) and extensions, the Company issued to the U.S. Treasury warrants (the “U.S. Treasury Warrants”) to purchase shares of the Company’s common stock under the Payroll Support Programs and Secured Loans (“PSP Loan”). The warrants have a five-year term from the date of issuance. The weighted average grant-date fair value of these warrants was estimated using the Black-Scholes option pricing model. The current holder of the warrants exercised 315,534 warrants during the year ended December 31, 2025. The Company settled the exercise through net cash disbursements totaling $1.1 million to the holder. As of November 25, 2025, the U.S. Treasury Warrants were reclassified from liability awards to equity awards upon the closing of the Merger as the Company may elect a cash or net share settlement. Prior to the Merger, as the Company’s common stock was not listed on a national securities exchange, the Company was required to net cash settle. As of December 31, 2025, the Company had 691,701
warrants issued and outstanding. On January 30, 2026, the Company adopted the Omnibus Amendment with the U.S. Treasury to settle the outstanding U.S. Treasury Warrants as of December 31, 2025 in cash. The U.S. Treasury Warrants were settled on February 18, 2026 totaling $5.3 million. As of February 18, 2026, the Company has no remaining warrants outstanding. The Company did not issue any warrants for the years ended December 31, 2025 and 2024.
Measurement of U.S. Treasury Warrants represents a Level 3 fair value measurement within the fair value hierarchy as defined by ASC 820, Fair Value Measurement. Fair value adjustments are recorded to investment income and other, net in the consolidated statements of operations. See Note 6, Fair Value Measurements.
Net income per common share—Basic and diluted net income per common share were as follows:

Basic net income per common share is computed by dividing net income attributable to the Company by the weighted average number of common shares outstanding during the period. The number of incremental shares from the assumed issuance of shares relating to restricted stock units and the exercise of warrants (excluding warrants with a nominal conversion price) is calculated by applying the treasury stock method. 344,237 weighted-average shares have been excluded from the calculation of diluted net income per common share for each period presented, as the related performance conditions have not been met.
Segment information—The Company is organized and operates as one operating and reportable segment: regional airline services. Substantially all of the Company’s revenues are derived from customers within the United States.
This determination is based on the management approach which designates internal information regularly available to the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of determination of the Company’s reportable segments. The Company’s CODM, the Chief Executive Officer, reviews financial information presented on a consolidated basis for the purpose of making operating decisions and assessing financial performance.
The accounting policies of the one reportable segment are the same as those described in the summary of significant accounting policies. The CODM uses income before income taxes, as reported in our consolidated statements of operations, to measure segment profit or loss, assess performance, and make strategic capital resources allocations. The measure of segment assets is reported on our consolidated balance sheets as total assets. The significant expense categories regularly provided to the CODM are the expenses as presented on the consolidated statements of operations.
Recent accounting pronouncements—In December 2023, the FASB issued ASU 2023-09—Improvement to Income Tax Disclosures (Topic 740), to provide clarifying guidance on the transparency of income tax disclosures. ASU 2023-09 is effective for public entities for annual reporting periods beginning after December 15, 2024. The Company adopted ASU 2023-09 on December 31, 2025 and applied the new disclosure requirements retroactively. Prior period disclosures have been adjusted to reflect the new disclosure requirement. The impact of the implementation to the
consolidated financial statements and related disclosures was not material. See Note 11, Income Taxes in the accompanying notes to the consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to provide investors with more granular detail on cost of sales, and selling, general, and administrative expenses. ASU 2024-03 is effective for public entities for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.
In May 2025, the FASB issued ASU 2025-03—Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity, which revises the guidance in ASC 805, Business Combinations, on identifying the accounting acquirer in a business combination in which the legal acquiree is a variable interest entity (“VIE”). ASU 2025-03 is effective for public entities with fiscal years beginning after December 15, 2026 with early adoption permitted. The Company early adopted ASU 2025-03 on January 1, 2025, and the impact of the implementation to the consolidated financial statements was not material.
In September 2025, the FASB issued ASU 2025-06—Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to improve the guidance related to the capitalization of software development costs. ASU 2025-06 is effective for public entities for fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.
In December 2025, the FASB issued ASU 2025-11—Interim Reporting (Topic 270): Narrow Scope Improvements, which clarifies the current requirements under Topic 270. The ASU provides a comprehensive list of required interim disclosures and requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for public entities for interim periods in fiscal years beginning after December 15, 2027 with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.

MERGER WITH MESA AIR GROUP, INC.
 12 Months Ended
Dec. 31, 2025
Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]  
MERGER WITH MESA AIR GROUP, INC. MERGER WITH MESA AIR GROUP, INC.
On November 25, 2025, Legacy Republic completed the Merger with Mesa Parent with the Mesa Parent legal entity continuing as the surviving corporation. Upon closing of the Merger, Mesa Parent was renamed Republic Airways Holdings Inc. The business conducted by the surviving corporation following completion of the Merger is primarily the business conducted by Legacy Republic, and beginning on November 25, 2025, includes the financial position, results of operations, and cash flows of pre-Merger Mesa Parent and subsidiaries, and is referred to on a post-Merger basis as the “Company.” The Company is led by executive leadership of Legacy Republic. Legacy Republic designated six of seven directors to the Board of Directors of the Company, while Mesa Parent designated one of seven directors.
Legacy Republic and Mesa Parent pursued the Merger in order to enhance the scale of the combined company, both financially and operationally, to create a larger single fleet type and to provide for greater access to capital markets. In addition, the Company pursued the Merger in order to obtain extended termination dates under a new 10-year CPA with United Airlines. 
In connection with the Merger and immediately prior to the effective time of the Merger (the “Effective Time”), Mesa Parent converted from a Nevada corporation to a Delaware corporation pursuant to a plan of conversion (the “Conversion”). At the Effective Time, each share of Legacy Republic common stock, par value $0.001 per share, (excluding (i) shares to be cancelled pursuant to the Merger Agreement and (ii) any dissenting shares for which appraisal rights were properly demanded in accordance with Delaware law) was converted into the right to receive 38.9933 (the “Exchange Ratio”) validly issued, fully paid and non-assessable shares of Mesa Parent common stock, par value $0.001, with cash paid in lieu of any fractional shares. Immediately prior to the Effective Time, each outstanding RSU in respect of shares of Legacy Republic common stock became vested and was cancelled. The Exchange Ratio gives effect to an unadjusted post-Merger capitalization of an 88.0% allocation to Legacy Republic pre-Merger shareholders, a 6.0%
allocation to Mesa pre-Merger shareholders, and a 6.0% allocation (the Escrow Shares discussed below) available for repayment of certain Mesa liabilities described below for the settlement of final working capital amounts and unsettled obligations of Mesa.
Further, Legacy Republic and Mesa Parent concurrently entered into the Three Party Agreement jointly with United Airlines to give effect to actions which facilitated an orderly wind down and disposition of certain assets, extinguishment of certain liabilities, and conditions not subject to the business combination and exchange of merger consideration. The Three Party Agreement provided for, among other things, completion of the following actions at and prior to the closing of the Merger:
(i) Termination of the United CPAs among Mesa and United Airlines;
(ii) Disposition by sale of certain Canadair Regional Jet (“CRJ”) aircraft, CRJ spare engines, an Embraer Regional Jet (“ERJ”) spare engine, and Boeing B-737 spare inventories;
(iii) Repayment of substantially all trade debts, long-term debts, and remaining liabilities of Mesa Parent and subsidiaries (“Mesa Net Debt”), utilizing the cash on hand of $19.6 million and cash proceeds from asset sales set forth in item (ii) above of $8.4 million. Upon depletion of Mesa Parent cash applied for the full and final satisfaction of trade debts, long-term debts, and remaining liabilities, United Airlines provided a one-time cash payment of $23.6 million for funding at Merger closing sufficient to discharge any obligations of Mesa Parent which remained outstanding at Merger close. As of November 25, 2025, all long-term debt encumbrances of Mesa Parent prior to Merger closing were discharged through repayment of amounts due or forgiveness by the counterparty;
(iv) Transfer of all Mesa rights and obligations related to its warrant and aircraft purchase agreements with Archer Aviation Inc. related to investments in, development of, and commitment for forward purchase of eVTOL aircraft to a third party;
(v) Extension of certain CPA terms between Mesa and United Airlines, including enhanced/increased rates retrospectively from January 2025 through termination of the CPAs concurrent with Merger closing, which enhanced the ability of Mesa to discharge those debts set forth in item (iii);
(vi) Issuance of 2,853,454 shares of common stock, par value $0.001, equivalent to approximately 6.0% of the issued and outstanding shares of the Company’s post-Merger common stock (the “Escrow Shares”).
Escrow Shares were settled February 9, 2026 following completion of a 60-day review and resolution period, which shares (a) first become allocable to United Airlines in exchange for the forgiveness and repayment of certain debts and obligations of Mesa; (b) second, to the extent any of the remainder become available to the Company to repay certain liabilities which were not known at Merger closing, and (c) third, to the extent of any remainder, become available on a pro rata basis to shareholders of Mesa immediately prior to consummation of the Merger and Merger-related agreements. During 2026, Escrow Shares of 2,744,348 were allocated to United Airlines in exchange for settlement and satisfaction of adjusted Mesa Net Debt of $51.7 million, and the residual 109,106 Escrow Shares were allocated to the Company, in satisfaction of the preceding item (b). Shares of common stock of the Company that were returned to the Company were retired upon receipt. No Escrow Shares were available for allocation to pre-Merger Mesa Parent shareholders.
The Company recorded an equity participation right of $2.3 million as of November 25, 2025 for the value of shares reallocated to the Company in final settlement of the Escrow Shares in the consolidated balance sheets and was included as a component of Merger consideration exchanged. Such amount was recorded as a reduction to additional paid-in-capital in the consolidated balance sheets. The effect of final allocation of the Escrow Shares results in an 88.1% interest in the Company held by pre-Merger Legacy Republic shareholders, a 6.0% interest in the Company held by pre-Merger Mesa Parent shareholders; and a 5.9% interest held by United Airlines, paid in full and final satisfaction of outstanding liabilities of Mesa Parent at Merger closing. The issuance of common stock to effectuate the Merger is as follows as of November 25, 2025:

(2)Fractional shares were settled in cash.
On September 24, 2025, Mesa Parent effected a change in its fiscal year historically ending on September 30 to align with the fiscal year of the Company ending on December 31, which became effective on January 1, 2025.
Prior to the Merger, effective at 6:00 p.m. Eastern Time on November 24, 2025, Mesa Parent effected the Reverse Stock Split. The consolidated financial statements and notes thereto include the effect of the 15-for-1 reverse stock split.
Further, on November 25, 2025, the Company entered into a new 10-year CPA with United Airlines and Mesa, now a wholly-owned subsidiary of the Company, to operate 60 E175 aircraft owned by United Airlines and operated by Mesa. Upon effectiveness of the new CPA, the Company received $49.0 million as a non-refundable up front fee funded by United Airlines to compensate for Merger-related expenses, and is recognized ratably on a straight-line basis to revenues over the 10-year term of the related CPA and was recorded to accounts payable and accrued and other expenses—related parties and other non-current liabilities—related parties in the consolidated balance sheets. The CPA in effect immediately prior to consummation of the Merger between Mesa Parent, Mesa, and United Airlines was terminated.
The Merger is accounted for as a reverse acquisition under provisions of FASB ASC 805, Business Combinations, using the acquisition method of accounting. Legacy Republic is designated the accounting acquirer and legal acquiree for financial reporting purposes on the basis that, immediately following consummation of the Merger, (i) shareholders of Legacy Republic hold a substantial majority of the voting interest in the Company, (ii) Legacy Republic designated six of seven director positions on the Company’s Board, and (iii) senior management of Legacy Republic retained all named executive officer positions within the Company following the Merger. The accounting for the Merger as a reverse acquisition resulted in the issuance and relinquishment of 11.9% of the pre-Merger voting interest in Legacy Republic as consideration in exchange for certain net assets of Mesa, which is measured at the acquisition date fair value of the consideration exchanged.
Merger consideration
Total Merger consideration exchanged is $120.2 million, consisting primarily of common stock, par value $0.001 exchanged. Under the reverse acquisition method of accounting for the Merger in accordance with ASC 805, Business Combinations, the fair value of purchase price consideration is the fair value of hypothetical stock issued to Mesa Parent pre-Merger shareholders as an estimate of the relinquished value of equity by the accounting acquirer. Merger consideration as of November 25, 2025 was as follows:

(2)Includes settlement of Escrow Shares allocable to the Company accounted for as an equity participation right in the consolidated balance sheet as of November 25, 2025.
Fair values of assets acquired and liabilities assumed
The acquisition method of accounting to comply with ASC 805, Business Combinations, requires, among other things, that assets acquired and liabilities assumed are recognized on the consolidated balance sheet at fair value as of the acquisition date, with certain exceptions. The fair values of assets acquired and liabilities assumed were determined using market comparisons for like assets of similar vintage and condition.
We have completed valuation analyses necessary to assess the fair values of the assets acquired and liabilities assumed and the amount of goodwill to be recognized as of the acquisition date. These fair values were based on management’s estimates and assumptions; however, the determination of fair values of assets acquired and liabilities assumed is preliminary and is subject to adjustment as additional information is obtained about the facts and circumstances that existed as of the acquisition date. Due to (i) the proximity of Merger-closing to the Company’s fiscal year end measurement date; (ii) the complexity of income tax estimates, and (iii) an ongoing Internal Revenue Service audit, management of the Company continues to evaluate its estimates and assumptions utilized to calculate fair values of inventories, property and equipment, goodwill, income taxes, accounts payable, and accrued and other liabilities as new information is obtained. Preliminary amounts reflected in the fair values of assets acquired and liabilities assumed will be adjusted to reflect new information obtained, as necessary, up to one year following Merger closing with corresponding adjustments to goodwill.
The Company recorded a preliminary allocation of Merger consideration to assets acquired and liabilities assumed based on their estimated fair values as of November 25, 2025. The following table summarizes the preliminary purchase price allocation, including resulting goodwill:

The composition of goodwill is principally derived from the assembled workforce of Mesa, whereby management derives a benefit from the aggregation of a highly-trained technical workforce which is not separable from goodwill. No other significant intangible assets are separately identifiable from goodwill. None of the goodwill is expected to be deductible for income tax purposes.
Additionally, the Company accounted for executive compensation for severance and consulting fees payable to Mesa Parent named executive officers separately from the Merger, as the negotiation and determination of such amounts, in part, were influenced by parties to the Three Party Agreement. Payment of $10.5 million was reimbursed by United Airlines for the related separation costs and was recorded on a net basis to executive separation and Merger-related items in the consolidated statements of operations and to accrued and other liabilities in the consolidated balance sheets as of December 31, 2025.

REVENUES

Dec. 31, 2025
Revenue from Contract with Customer [Abstract]  
REVENUES REVENUES
The Company accounts for contracts with our Partner Airlines under ASC 606, Revenue from Contracts with Customers, and ASC 842, Leases, as applicable, when each party has committed to perform under the contract, each party’s rights and payment terms have been established, when the contract has commercial substance, and when collectability of amounts due under the contract is probable. Under CPAs with our Partner Airlines, the Company has
committed to perform various flight services and maintenance activities classified as regional jet services. Within regional jet services, flight services represent a series of distinct activities accounted for as a single performance obligation satisfied over time as flights are completed. The Company recognizes certain maintenance activities as separate performance obligations, which are satisfied as the related distinct service is complete. Substantially all of the Company’s revenues are generated from regional jet services.
Revenues associated with regional jet services are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred and a fixed rate for available-to-schedule aircraft, payable on a monthly basis; and (ii) a premium amount which is earned monthly and quarterly by maintaining minimum aircraft utilization levels and exemplary operating results. To the extent that minimum targets are not achieved, the Company could be subject to financial penalties. These fixed-fee rates are contractually subject to periodic economic adjustment. The Company additionally receives reimbursement from our Partner Airlines for direct expenses incurred such as qualifying maintenance activities, property taxes, and miscellaneous operating expenses. Certain charges such as fuel, landing fees, and certain ownership costs are generally paid directly by the Partner Airlines, although the charges were incurred by the Company in ongoing operations. The Company refers to these charges as “Partner direct charges.” Pass-through charges are primarily recorded to revenues and the corresponding operating expense on a gross basis. Pass-through charges recorded on a net basis are not material.
Amounts recognized as regional jet services revenues are measured at the contractual amount the Company expects it will be entitled to in exchange for the promised services. The Company allocates the transaction price as flights are completed with variable consideration that relates specifically to the Company’s efforts in delivering each flight recognized in the period in which the individual flight is completed and measured on a monthly basis. The Company records an estimate for incentive revenue based on our expected performance at the end of each period. These estimates are derived under accounting guidance related to variable consideration constraints and based on amounts expected to be collected. The Company has concluded that allocating the variability directly to individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that generally follows the variable amounts billed from the Company to Partner Airlines. As allowed with ASC 606, the Company has elected to apply practical expedients to expense significant financing components and the incremental costs of obtaining a contract as incurred.
A portion of the Company’s compensation under its CPAs is designed to reimburse the Company for certain aircraft ownership costs. The Company has concluded that a component of its revenue under the CPAs is deemed to be embedded lease revenue and as such, agreements identify the right-of-use of a specific type and number of aircraft over the term of the CPA. Embedded lease revenue associated with the Company’s CPAs is accounted for as an operating lease under ASC 842, Leases.
American Airlines
During the year ended December 31, 2023, the Company and American Airlines reached agreement for a four-year extension of 76 E175 aircraft under operation according to the CPA, which became effective on January 1, 2024. In addition, during the year ended December 31, 2024, the Company sold six E175 aircraft to American Airlines for proceeds of $49.3 million, net of debt repayment and fees.

United Airlines
The Company entered into a CPA with United Airlines during the year ended December 31, 2021, for the replacement of 38 E170 aircraft with new E175 aircraft for scheduled passenger service over a 12-year term, including certain customary right-of-use aircraft leasing terms. The Company placed 34 aircraft into service since inception of the CPA. Additionally, the Company further repositioned 34 E170 aircraft from the United Airlines CPAs based on scheduled United Airlines CPA expiries during the years then ended. The remaining four aircraft are expected to be operating on the
United Airlines CPAs during the year ending December 31, 2026, which includes one aircraft delivered during the year ended December 31, 2025, which had not yet commenced revenue service.
Further, on November 25, 2025, the Company entered into a new 10-year CPA with United Airlines and Mesa, to operate an additional 60 E175 aircraft owned by United Airlines and operated by Mesa Airlines, Inc. In relation to the Merger with Mesa, the Company received $49.0 million as a non-refundable upfront fee from United Airlines to cover expenses related to the Merger and is recognized in accounts payable and accrued and other liabilities-related parties and other non-current liabilities-related parties in the consolidated balance sheets as of December 31, 2025. The fee is being amortized ratably on a straight-line basis over the respective CPA term.

(1)Certain of the Company’s CPAs include embedded leases for the right-of-use of the regional jet aircraft. The Company also leases 31 aircraft not under CPAs to American Airlines. The corresponding rental income is classified herein.
LIFT Academy recorded tuition revenue of $23.2 million, $19.3 million, and $11.6 million during the years ended December 31, 2025, 2024, and 2023, respectively. Tuition payments received from students are recognized as deferred revenue and reflected in accrued and other liabilities in the consolidated balance sheets and are recognized on a systematic basis as students progress throughout their respective training programs.
Amounts recognized as revenues in the consolidated statements of operations are subject to certain estimates, which could materially impact the timing and consideration determined under the contract. Such estimates include (i) expected contract terms from material modifications to the fixed-fee capacity purchase agreements which are expected to be made in the future and (ii) the extent to which disputes in contract interpretation arise.
Receivables and contract assets—Receivables represent a right to consideration for promised services which have been transferred to customers. The Company records provisions for credit losses using an expected credit losses model on the basis of specific identification and historical collection experience. For more information on credit losses, refer to Note 17, Valuation and Qualifying Accounts.
Contract assets are generated from the partial satisfaction of certain performance obligations, generally related to the delivery of aircraft maintenance services, under customer contracts whereby the Company has the right to consideration for services transferred or provided to its customers. Other current assets—related parties and other non-current assets—related parties in the consolidated balance sheets consist entirely of contract assets, which have been appropriately reduced for the applicable financing component. The Company expects to collect all current amounts within the next twelve months, while non-current amounts will be collected over the period from 2027 to 2030.
Contract liabilities—Contract liabilities consist of deferred revenues for which the Company has received customer payment for undelivered services. In addition, the Company periodically carries out capital projects on behalf of its Partner Airlines, generally pertaining to aircraft fleet and livery improvements. Revenues of this nature are recognized over time, depicting the pattern of transfer of control of services, resulting in ratable recognition of revenues over the remaining term of the CPA, ranging from 2026 - 2036.
Current and non-current deferred revenues are recorded to accounts payable and accrued and other liabilities-related parties and other non-current liabilities-related parties, respectively, in the consolidated balance sheets. The Company recognized $16.1 million, $13.7 million, and $10.8 million of the deferred revenue to revenues in the consolidated statements of operations during the years ended December 31, 2025, 2024, and 2023, respectively, which was previously included in contract liabilities at December 31, 2024, 2023, and 2022, respectively. Current contract liabilities were $35.9 million and $22.7 million as of December 31, 2025 and 2024, respectively. Non-current contract liabilities were $103.2 million and $41.8 million as of December 31, 2025 and 2024, respectively.

FAIR VALUE MEASUREMENTS
 12 Months Ended
Dec. 31, 2025
Fair Value Disclosures [Abstract]  
FAIR VALUE MEASUREMENTS FAIR VALUE MEASUREMENTS
The Company holds certain financial instruments, which require measurement to fair value in accordance with ASC 820, Fair Value Measurement. The Company measures the following financial instruments on a recurring basis:
Cash, cash equivalents, and restricted cash—The carrying amounts of cash, cash equivalents, and restricted cash reported in the consolidated balance sheets are classified as a Level 1 fair value measurement in the ASC 820, Fair Value Measurement, fair value hierarchy. Amounts presented in the consolidated balance sheets approximate the respective fair values using a market valuation technique.
Marketable securities—Investments in marketable securities primarily include U.S. Treasury securities and are recorded at fair value. Valuation of securities is based on reference to the quoted market price on national exchanges, representing Level 1 fair value measurements as defined in ASC 820, Fair Value Measurement. Unrealized and realized gains and losses are recorded to investment income and other, net, in the consolidated statements of operations. Amounts recorded for unrealized and realized gains for the years ended December 31, 2025, 2024, and 2023 were $7.7 million, $10.6 million, and $5.5 million, respectively.
EVE Investment—During the year ended December 31, 2022, the Company acquired 1,000,000 shares of Class A Common Stock in EVE for which Embraer S.A., a related party, through its wholly-owned subsidiary Embraer Aircraft Holdings, Inc., possesses beneficial ownership of EVE. Shares were acquired for a purchase price of $10.00 per share (“EVE Equities”) in furtherance of a commercial partnership among certain initial investors for the development of eVTOL aircraft. Additionally, as an inducement to enter into the partnership, the Company obtained (i) warrants for the acquisition of an additional 1,500,000 shares of Class A Common Stock in EVE at an exercise price of $0.01 per share, subject to a three year lock-up period, exercisable through May 2027 (the “EVE Warrants”) and (ii) a put option for reacquisition of EVE Class A Common Stock by EVE or a subsidiary of EVE for the aggregate put price of $10.0 million, exercisable on demand through May 2032 (the “Put Option”) (collectively with the EVE Equities, EVE Warrants, and the Put Option, the “EVE Investment”). The Put Option is redeemable in future aircraft parts and maintenance services.
The EVE Equities are subject to provisions of FASB ASC 321, Investments. The investment was initially measured at fair value and was recorded to other non-current assets in the consolidated balance sheets. EVE Equities represent a Level 1 investment within the FASB ASC 820, Fair Value Measurement, fair value hierarchy, as the inputs for shares of EVE common stock are observable and actively exchange-traded. As of December 31, 2025 and 2024, the Company recorded $4.0 million and $5.4 million, respectively, attributable to the fair value of EVE Equities to other non-current assets in the consolidated balance sheets. The Company recorded unrealized gains (losses) of ($1.5) million, ($1.9) million, and $0.1 million related to the EVE Equities to investment income and other, net, in the consolidated statements of operations during the years ended December 31, 2025, 2024, and 2023, respectively.
EVE Warrants and the Put Option issued in conjunction with the EVE Investment are characterized as financial instruments and manufacturer incentives, respectively, for redemption toward future eVTOL aircraft acquisitions, aircraft parts, and/or maintenance services for the regional jet aircraft. Financial instruments related to the EVE Warrants and Put Option are recorded to other non-current assets at the estimated fair value at issuance and subsequently adjusted to fair value at each reporting date. Manufacturer incentives are recorded to other non-current liabilities in the consolidated balance sheets. Incentives utilized for future aircraft and equipment purchases will be applied as a reduction to the aircraft basis upon delivery.
The Company recorded $17.5 million in manufacturer incentives to other non-current liabilities related to the EVE Warrants and Put Option, which was fixed at the consummation of the Eve Investment during the year ended December 31, 2022. During the years ended December 31, 2025, 2024, and 2023, the Company recorded unrealized gains (losses) of ($2.2) million, ($2.8) million, and $0.2 million related to fluctuations in fair value of the EVE Warrants, respectively. Fluctuations in fair value related to the Put Option were not material. As the EVE Warrants and Put Option are adjusted to fair value at each reporting period in accordance with FASB ASC 815, Derivatives and Hedging, and the related manufacturing incentive is fixed at issuance date in accordance with FASB ASC 705-20, Cost of Sales and Services – Accounting for Consideration, the Company will continue to record unrealized gains or losses associated with the change in fair value of the EVE Warrants and Put Option in earnings despite no economic loss to the Company based on the terms of the EVE agreements and economic substance of the aggregate EVE Investment.
The Company estimates the fair value of EVE Warrants and the Put Option using a Black-Scholes option pricing model. This market-based approach relies on the use of significant unobservable inputs, and therefore, such amounts are classified as Level 3 fair value measurements within the ASC 820, Fair Value Measurement, fair value hierarchy. The significant unobservable input used in the Black-Scholes option pricing model in the valuation of the EVE Investments is the implied volatility using the comparison of stock prices of comparative eVTOL companies of similar size.

As of December 31, 2024, U.S. Treasury Warrants were classified as liability awards and were recognized at fair value and adjusted at each reporting date thereafter using the Black-Scholes option pricing model using an implied volatility calculated by the comparison of stock prices of select airlines of similar size and/or an income approach to determine fair value of the equity of the Company, reporting a Level 3 fair value measurement as defined in the ASC 820, Fair Value Measurement fair value hierarchy.
In conjunction with the Merger closing, the U.S. Treasury Warrants were reclassified from liability awards to equity awards based on the underlying characteristics of the warrants and manner of future settlement of the awards. The Company reclassified $7.4 million for the U.S. Treasury Warrants from accrued expenses in the consolidated balance sheets to additional paid-in-capital in the consolidated balance sheets and discontinued measurement of the U.S. Treasury Warrants to fair value at each reporting date. The carrying value of the U.S. Treasury Warrants was $7.4 million as of December 31, 2025.
The Company recorded unrealized gains (losses) of $(1.7) million, $0.2 million, and $(1.2) million to investment income and other, net in the consolidated statements of operations related to fair value adjustments of the U.S. Treasury Warrants for the years ended December 31, 2025, 2024, and 2023, respectively.
During the year ended December 31, 2025, the U.S. Treasury exercised 315,534 of their existing Warrants for $1.1 million in cash. Remaining U.S. Treasury Warrants outstanding as of December 31, 2025 were 691,701, exercisable through July 15, 2026.
On January 30, 2026, the Company adopted the Omnibus Amendment with the U.S. Treasury to settle the outstanding U.S. Treasury Warrants as of December 31, 2025 in cash. The U.S. Treasury Warrants were settled on February 18, 2026 totaling $5.3 million. As of February 18, 2026, the Company has no remaining warrants outstanding.
The implied volatility, which is the unobservable input, used in the determination of fair value of Level 3 investments for the years ended December 31, 2025 and 2024 is as follows:
20252024
EVE Investment

The increase or decrease in the fair value measurement of the implied volatility may result in a higher or lower effect on the fair value measurement of the Company’s EVE Investment. The amount recorded to other non-current assets as of December 31, 2025 and 2024 for the aggregate EVE Warrants and the Put Option was $11.4 million and $13.3 million, respectively.

During the year ended December 31, 2023, the Company remeasured the value of its investment in Cape Air on a non-recurring basis for declines in value which may be other than temporary. The Company valued the investment in Cape Air under the discounted cash flow method. Therefore, it is considered a Level 3 fair value measurement under ASC 820, Fair Value Measurement. In response, the Company recorded a $3.6 million reduction in value to investment income and other, net in the consolidated statement of operations which will be subsequently amortized over the useful life of Cape Air aircraft of 15 years in accordance with ASC 323, Investments—Equity Method Investments & Joint Ventures.
Market risk associated with our fixed-rate debt primarily relates to the potential change in fair value and impact to future earnings, respectively, from a change in prevailing market interest rates. Within the fair value hierarchy, the fair value of debt is based predominantly on a market approach, looking to recently completed market transactions and estimates based on interest rates, maturities, credit risk, and underlying collateral. These inputs are classified as Level 3 fair value measurements within the fair value hierarchy. The fair value of debt, including current maturities and excluding finance leases, exceeded its carrying value by $10.8 million as of December 31, 2025. The carrying value of long-term debt exceeded its fair value by $11.5 million as of December 31, 2024.

LEASES

Dec. 31, 2025
Leases [Abstract]  
LEASES LEASES
The Company routinely enters into operating and finance leases as a financing method for aircraft, spare engines, flight training equipment, and operating facilities. The Company records a lease asset and corresponding liability for leases with terms exceeding 12 months. Such assets and liabilities are measured at the present value of remaining lease payments at the commencement of the lease or consummation of a lease modification.
Lease terms give effect to early termination and renewal options when it is reasonably certain that such options will be exercised. The Company determines present value, discounting payment streams at the interest rate implicit in the lease, when available, taking into consideration economic escalation provisions, when applicable. When this information is unknown, the Company estimates its incremental borrowing rate at the related lease commencement date, which is derived from prevailing market interest rates, recent debt acquisitions specific to the Company, or other debt instruments having similar characteristics at lease commencement. With the exception of the CPAs and operating facilities, the Company does not separate lease and non-lease contractual components. Provisions for residual value guarantees are not material.
As part of the Merger, the Company acquired leases, three of which are classified as operating in the consolidated balance sheets as of December 31, 2025. The Company measured the operating lease liabilities at present value of the remaining lease payments on the Merger date in accordance with ASC 805, Business Combinations. Further, the Company measured the right-of-use asset in exchange for the operating lease liabilities assumed and adjusted for comparable market terms on the Merger date. As a result, such leases increased operating right-of-use assets and operating lease liabilities by $7.1 million and $6.7 million, respectively. The Company elected to not recognize assets or liabilities with remaining terms of 12 months or less as a practical expedient permitted under ASC 805, Business Combinations. Refer to Note 3, Merger with Mesa Air Group Inc., for more information.
Aircraft and engines—As of December 31, 2025, the Company is party to non-cancelable operating and financing lease agreements related to 23 aircraft and 13 spare engines with varying terms extending through 2031. Of the 23 leased aircraft and 13 leased engines, 12 and nine are leased directly from Partner Airlines (“Partner Controlled Aircraft”), respectively, constituting related party lease obligations. See Note 16, Related Party Transactions. Lease terms generally coincide with the related CPA expiry.
Operating facilities—The Company’s leased operating facilities include airport terminal space, hangars and maintenance facilities, office space, and training facilities with initial terms extending from 30 days to 13 years, classified as operating leases and short-term leases. Airport terminal space, which includes crew rooms and line maintenance facilities, is generally leased directly from a governmental agency or authority. Rental rates are dependent on actual airport operating costs and require adjustment at least annually. As a result of the variable nature of rent, airport terminal space leases are not recorded to the operating lease right-of-use asset and operating lease liabilities.
Flight training equipment—The Company maintains a long-term supply agreement for fulfillment of full motion flight simulation equipment at a guaranteed minimum level through 2033 with additional capacity availability accounted for as operating leases. Pursuant to this arrangement, the Company leases training equipment, embedded with related maintenance service agreements. The Company has elected the practical expedient permissible under ASC 842, Leases, and as a result, the non-lease service component has not been separated and removed from the operating lease right-of-use assets and related operating lease liabilities.

Aircraft leasing arrangements—The Company’s CPAs include provisions for the right-to-use of the Company’s aircraft in carrying out regional jet services. Such provisions constitute embedded leases for which the Company receives reimbursement for aircraft ownership costs, as Partner Airlines obtain substantially all of the economic benefit from the
aircraft under operation for the Partner Airlines. Aircraft lease terms are commensurate with CPA terms discussed at Note 5, Revenue Recognition. The Company mitigates the risk from residual and undeployed leased assets in the event of default of one of our Partner Airlines by actively monitoring aircraft and engine financing terms compared to market terms in order to effectively sell or redeploy aircraft to the extent they become unused or underutilized, which additionally decreases with the extent to which the Company operates Partner Controlled Aircraft.

LEASES LEASES
The Company routinely enters into operating and finance leases as a financing method for aircraft, spare engines, flight training equipment, and operating facilities. The Company records a lease asset and corresponding liability for leases with terms exceeding 12 months. Such assets and liabilities are measured at the present value of remaining lease payments at the commencement of the lease or consummation of a lease modification.
Lease terms give effect to early termination and renewal options when it is reasonably certain that such options will be exercised. The Company determines present value, discounting payment streams at the interest rate implicit in the lease, when available, taking into consideration economic escalation provisions, when applicable. When this information is unknown, the Company estimates its incremental borrowing rate at the related lease commencement date, which is derived from prevailing market interest rates, recent debt acquisitions specific to the Company, or other debt instruments having similar characteristics at lease commencement. With the exception of the CPAs and operating facilities, the Company does not separate lease and non-lease contractual components. Provisions for residual value guarantees are not material.
As part of the Merger, the Company acquired leases, three of which are classified as operating in the consolidated balance sheets as of December 31, 2025. The Company measured the operating lease liabilities at present value of the remaining lease payments on the Merger date in accordance with ASC 805, Business Combinations. Further, the Company measured the right-of-use asset in exchange for the operating lease liabilities assumed and adjusted for comparable market terms on the Merger date. As a result, such leases increased operating right-of-use assets and operating lease liabilities by $7.1 million and $6.7 million, respectively. The Company elected to not recognize assets or liabilities with remaining terms of 12 months or less as a practical expedient permitted under ASC 805, Business Combinations. Refer to Note 3, Merger with Mesa Air Group Inc., for more information.
Aircraft and engines—As of December 31, 2025, the Company is party to non-cancelable operating and financing lease agreements related to 23 aircraft and 13 spare engines with varying terms extending through 2031.

During the year ended December 31, 2025, the Company obtained aggregate borrowings of $299.4 million consisting of new aircraft debt of $255.5 million secured by 12 factory new E175 aircraft, $1.2 million collateralized general aviation aircraft, and $42.7 million secured by a complement of spare engines. Payments on aggregate borrowings obtained are due in quarterly installments with terms ranging from five to 12 years.
During the year ended December 31, 2024, the Company obtained aggregate borrowings of $177.3 million consisting of new aircraft debt of $126.2 million secured by six factory new E175 aircraft and $51.1 million collateralized or re-collateralized by a complement of regional and general aviation aircraft. Payments on aggregate borrowings obtained are due in quarterly installments with terms ranging from four to 12 years. Additionally, during the year ended December 31, 2024, the Company made early debt extinguishments of $37.4 million in secured aircraft loans, plus accrued and unpaid interest expense related to the sale and disposition of the underlying aircraft.
Real Estate Debt—During the year ended December 31, 2023, the Company entered into a loan agreement for aggregate borrowings of $52.0 million which is collateralized by a portion of the Company’s new flight training campus and corporate headquarters in Carmel, Indiana (the “Aviation Campus”). Borrowings under the loan agreement bear interest at SOFR plus a stated margin with scheduled maturities through 2025. During the year ended December 31, 2025, the Company executed a one-year extension to the scheduled maturity through the year ending December 31, 2026 and has the option to extend for two additional one year terms. Repayment obligations may be accelerated at the Company’s option without penalty.
Equipment Debt—During the year ended December 31, 2023, the Company formed a pass-through trust for the sale of Class A Certificates (“Enhanced Equipment Trust Certificates” or “EETC”). The trust, in turn, gave effect to the sale of Series A Equipment Notes secured by certain of the Company’s spare aircraft equipment, generating aggregate proceeds of $118.0 million for general corporate purposes. Repayment of the Series A Equipment Notes occurs on a
specified maturity schedule through 2028 with regularly scheduled interest payments at 8.0% per annum. Repayment obligations may be accelerated at the Company’s option, subject to customary early termination provisions.
The Company evaluated whether the pass-through trust formed for administration of Equipment Debt is a variable interest entity (“VIE”) requiring potential consolidation within the consolidated financial statements. Although the pass-through trust constitutes a VIE, the Company is not the primary beneficiary of the trust and therefore it is not presented within these consolidated financial statements.
The Series A Equipment Notes include customary financial covenants pursuant to which the Company must maintain a certain loan-to-value ratio of the regularly appraised value of underlying spare parts.
Payroll Support Program Loans—The Payroll Support Program (“PSP”) loans are unsecured borrowings with scheduled maturities of the total outstanding principal obligation at the ten-year anniversary of each initial draw (“PSP Loan Term”). PSP Loans bear interest at an indexed rate plus 2.0%, payable on a quarterly basis over the PSP Loan Term. Voluntary pre-payment is permissible at any time without penalty.
Our credit agreements require that we comply with customary affirmative and negative covenants. Management believes the Company is in compliance with all of its financial covenants as of December 31, 2025 and 2024.
As of December 31, 2025 and 2024, the Company had 100% cash collateralized letter of credit facilities of $22.8 million and $21.4 million, respectively. Amounts are recorded in restricted cash in the consolidated balance sheets.

(1)Change in valuation allowance includes the Mesa valuation allowance as of the Merger closing date, which does not impact provision for income tax expense.
The Company’s deferred tax assets were generated as a result of temporary differences between deductibility of reserves, accruals, and operating lease liabilities and recognition of revenue for the determination of income on a tax basis versus a U.S. GAAP basis combined with significant NOLs. Deferred tax liabilities relate predominantly to differences in U.S. GAAP and tax basis of aircraft and equipment and the related right of use assets created as the present value of remaining lease payments at the measurement date. The Company accelerates depreciation for tax reporting purposes for new aircraft and equipment deliveries.
The Company monitors ongoing tax cases related to its unrecognized tax benefits. The unrecognized tax benefits, which if recognized, would impact the effective tax rate. As of December 31, 2025 the Company has reversed all liabilities related to unrecognized tax benefits due to the expiration of the statute of limitations.

As of December 31, 2025, the Company has Federal NOL carryforwards totaling approximately $300 million, of which a portion begin expiring during 2036. Approximately $190 million of our Federal NOL carryforwards are not subject to expiration. These NOL carryovers are only available to offset 80% of taxable income in years in which they are utilized due to tax law changes as a result of the Tax Cuts and Jobs Act. The Company also has $70 million of interest expense carryovers as a result of 163(j) limitations as of December 31, 2025, which do not expire. Tax years beginning in 2007 through 2025 are currently subject to examination by the Internal Revenue Service.
The Company cannot conclude that it is more likely than not that the benefit from certain Federal and state NOL carryforwards will be realized. In recognition of this uncertainty, the Company has provided a valuation allowance of $82.7 million and $36.4 million as of December 31, 2025 and 2024, respectively, on the deferred tax assets related to these NOL carryforwards. If or when recognized, the tax benefits related to any reversal of the valuation allowance on deferred tax assets will be recognized as a reduction of income tax expense.

Commitments and Contingencies Disclosure [Abstract]  
COMMITMENTS COMMITMENTS
The Company’s long-term commitments primarily include lease obligations (see Note 7, Leases), long-term maintenance agreements, and purchase commitments, among others.
Long-term maintenance—The Company has long-term agreements relating to maintenance costs associated with engines, auxiliary power units (“APUs”), avionics, and other flight equipment. The following agreements comprise the Company’s long-term maintenance agreements for various airframe and engine components as of December 31, 2025:
Maintenance Agreement
Termination
APUs
December 2034
Avionics
December 2029
Engines
December 2037
Wheels and Brakes
September 2030
Certain fixed agreements include a guaranteed minimum payment amount based on flight hours, departures, or other measures. Aggregate payments under long-term maintenance agreements were $154.0 million, $149.4 million, and $150.8 million for the years ended December 31, 2025, 2024 and 2023, respectively.
Purchase commitments—From time to time, the Company enters into purchase commitments for future aircraft and engine deliveries. The Company regularly makes pre-delivery deposit payments (“PDPs”) to support aircraft and engines on order. PDPs are retained and applied against the historical cost of the corresponding aircraft or engine at the time of its acquisition or expensed when deposit amounts are no longer expected to be returned from the manufacturer. Interest costs associated with PDPs are capitalized as a portion of the overall historical cost of the related aircraft or engine and are depreciated over the estimated useful life of the asset. The Company recorded $2.1 million and $1.6 million, respectively, in capitalized interest costs to property and equipment, net, in the consolidated balance sheets as of December 31, 2025 and 2024, respectively.
Republic has an order for 29 Embraer regional jets (E175) with deliveries through 2029.
During the year ended December 31, 2025, the Company executed an amendment to an existing financing commitment to finance contractually scheduled aircraft deliveries during the year ending December 31, 2026, which provides future funding for a portion of the total aircraft cost. Committed future borrowings are expected to be secured by the related aircraft and funded upon each delivery. Additionally, the Company obtained commitments for a future credit facility secured by spared engines As of December 31, 2025, the remaining maximum borrowings allowable under the agreements is $115.6 million.
In each of the three years ended December 31, 2025, 2024, and 2023, the Company completed certain milestones in the construction of the Aviation Campus. The Aviation Campus houses a training center that, once fully integrated with pre-Merger Mesa Airlines operations, will be used to perform substantially all of the Company’s training activities for pilots, flight attendants, maintenance technicians, and dispatchers and houses eight full motion simulators along with flat panel simulators, cabin trainers, and classrooms. Additionally, the Aviation Campus includes overnight accommodations used exclusively by the Company’s associates in training, our corporate headquarters (completed January 2026), and a parking garage. The Company additionally began construction on additional overnight accommodations, which is expected to be completed in 2026. As of December 31, 2025 and 2024, the Company recorded $2.9 million and $1.3 million, respectively, in capitalized interest costs to property and equipment, net, in the consolidated balance sheets associated with the construction of the Aviation Campus.

CONTINGENCIES

Commitments and Contingencies Disclosure [Abstract]  
CONTINGENCIES CONTINGENCIES
General indemnifications—The Company is a party to aircraft lease and financing arrangements, which include provisions requiring the Company to indemnify the lessor or financing party against certain losses which may arise from use of the related aircraft and equipment, including losses arising from tax consequences. The Company expects that such losses would constitute insurable losses and would therefore be subject to insurance coverage. Losses expected to arise from indemnities cannot be reasonably determined due to the uncertainty surrounding circumstances which may give rise to losses, or the amount of expected losses which could arise.
Legal matters—The Company is involved in various legal actions considered routine to the ordinary course of business. Contingent losses expected to arise as a result of pending legal matters, which could include expected future settlements, judgments, and legal fees are recorded when amounts become probable and are able to be estimated. Estimated future losses and legal fees related to ongoing litigation were not material as of December 31, 2025 and 2024.
While the Company cannot predict the outcome of these events with certainty, management does not believe pending legal matters would have a material effect on the results of operations, cash flows, or financial position.
Employees under collective bargaining agreements—As of December 31, 2025, the Company employed approximately 8,400 employees. Of the Company’s total headcount, approximately 71% of the employee base is represented by collective bargaining agreements as follows:

Stock Compensation
During the year ended December 31, 2020, the Company adopted the 2020 Omnibus Incentive Plan and issued RSUs to the Company’s Board of Directors. RSUs vested immediately with a contractual sale restriction until the earlier of the Merger closing or termination of the participant’s service to the Company’s Board of Directors. In the event a market did not exist for the RSUs, the agreement provided for certain put rights for the RSUs to be put to the Company at fair market value. The put rights required these RSUs to be classified in mezzanine equity. The amount presented in mezzanine equity in the consolidated balance sheet as of December 31, 2024 is based on the accumulated expense of the RSUs in accordance with ASC 718, Compensation—Stock Compensation. The Company issued 57,047 RSUs under the 2020 Omnibus Incentive Plan during the year ended December 31, 2025, at an estimated grant date fair value of $15.39 per share. No RSUs were issued during the year ended December 31, 2024.
Additionally, since 2020, the Company issued 482,542 RSUs to certain members of management of the Company (“Value and Performance RSUs”). The Value and Performance RSUs included a market condition that could decrease the number of units to be issued if the fair market value of the Company did not increase over 30% by December 31, 2025. The Value and Performance RSUs also included a performance condition multiplier up to 300% of the units issued based on the occurrence of a liquidity event as determined by the Company’s Board of Directors and an increase in the fair market value of the Company as of a liquidity event date. The performance condition was not probable to occur as December 31, 2024, and therefore no expense was recognized related to the performance condition during the year then ended.
Prior to closing of the Merger, the Value and Performance RSU agreements provided certain put rights for the units to be put to the Company at fair market value. Such provisions required that these Value and Performance RSUs were classified in mezzanine equity. The Company recorded share based compensation for these awards at the grant date fair value of $7.50 per share, which was determined using a Monte Carlo simulation model considering the market condition but not including the performance condition as it was not probable until closing of the Merger. The Value and Performance RSUs became fully vested on November 25, 2025 concurrent with closing of the Merger, which was a liquidity event as defined in the performance vesting conditions of the Value and Performance RSU awards. Upon closing, the remaining outstanding Value and Performance RSUs vested resulting in the issuance of 284,700 additional shares in satisfaction of
the performance vesting condition. Amounts were reclassified from mezzanine equity to common stock and additional paid-in capital upon closing of the Merger as the Value and Performance RSUs were settled for common stock.
The Company recorded cumulative share based compensation expense related to the Value and Performance RSUs with performance-based vesting conditions during the year ended December 31, 2025, as well as the acceleration of the vesting of the award. The Company recorded $2.1 million and $0.8 million of share based compensation to executive separation and Merger-related items and wages and benefits expense in the consolidated statements of operations, respectively, related to these Value and Performance RSUs during the year ended December 31, 2025, including satisfaction of performance conditions. There is no unrecognized remaining compensation cost related to the Value and Performance RSUs as of December 31, 2025.
In addition, during the year ended December 31, 2025, the Company granted 191,769 RSUs (“Time Based Restricted Stock Awards”) to certain key members of management of the Company. The Time Based Restricted Stock Awards include a vesting condition and vest ratably each year over a three-year vesting period. The estimated grant date fair value of each Time Based Restricted Stock Award was $15.39 per share. During the year ended December 31, 2025, the Company recorded $1.1 million in share based compensation to wages and benefits expense in the consolidated statements of operations. As of December 31, 2025, the total unrecognized compensation cost related to these non-vested shares that the Company expects to recognize over a weighted average of approximately one year is $0.7 million. The Company accounts for forfeitures as they occur.
Also, during the year ended December 31, 2025, the Company granted 1,147,456 RSUs to certain key members of management, which are subject to both time- and performance-based vesting conditions (the “Republic Integration Awards”). The Republic Integration Awards and the Time Based Restricted Stock Awards, each, were unvested RSUs in Legacy Republic, which were automatically assumed and converted into the right to receive a restricted share award in respect of common stock of the Company.
The Republic Integration Awards subject to time-vesting conditions and vest in equal installments on the third and fourth anniversaries of closing of the Merger, subject to continued employment of the RSU holder. The Republic Integration Awards subject to performance-vesting conditions vest in one-third tranches upon achievement of specified operational milestones. During the year ended December 31, 2025, the Company recorded $5.1 million in share based compensation to wages and benefits expense in the consolidated statements of operations. As of December 31, 2025, the total unrecognized compensation cost related to these non-vested shares that the Company expects to recognize over a weighted average of approximately two years is $12.6 million.
In connection with Mr. Bedford’s retirement from the Company, effective July 1, 2025, 367,512 RSUs held by Mr. Bedford, previously classified as mezzanine equity, were modified, and an additional 284,963 RSUs were granted. All RSUs were considered earned and vested immediately. The recognition of Mr. Bedford’s awards resulted in $9.8 million of additional compensation expense during the year ended December 31, 2025 which was recorded to executive separation and Merger-related items in the consolidated statements of operations.
The following table summarizes the activity of RSUs granted to certain employees of the Company for the years ended December 31, 2025, 2024, and 2023:

DEFINED CONTRIBUTION PLANS DEFINED CONTRIBUTION PLANS
The Company sponsors defined contribution 401(k) plans (the “401(k) Plans”). The 401(k) Plans provide retirement savings alternatives to associates. In accordance with 401(k) Plan rules, associates may elect pre-tax deferrals, after-tax Roth deferrals, or a combination thereof, from eligible compensation. The Company matches up to 8.0% of non-crew associates’ eligible compensation, and the related employer matching contributions are immediately vested.
Additionally, the Company maintains agreements with IBT, Local 357 and IBT, Local 135, representing the pilot and flight attendant labor groups, respectively. Under each CBA, the Company contributes up to a 12.0% employer contribution and 8.0% employer matching contribution over a five-year vesting period for pilots and flight attendants, respectively. In connection with the Merger, the Company retained defined contribution plans in place at Mesa Parent prior to Merger closing (“Legacy Mesa Plan”). The Legacy Mesa Plan matches 50.0% of salary deferrals up to 10.0% of eligible compensation over a four-year vesting period. The Company’s compensation expense related to 401(k) Plans and the Legacy Mesa Plan on an aggregate basis was $31.0 million, $28.6 million, and $27.7 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Related Party Transactions [Abstract]  
RELATED PARTY TRANSACTIONS RELATED PARTY TRANSACTIONS
The Company’s related party transactions include transactions with our Partner Airlines and an original equipment manufacturer (the “Related Parties”), with whom we have held long-standing relationships.
The Company regularly transacts with its Related Parties as defined in ASC 850, Related Parties, in the ordinary course of business. Related party transactions are derived from passenger service under the capacity purchase relationships, certain aircraft leasing commitments between the Company and the Partner Airlines, and aircraft maintenance activities, which in turn, generate balances due to or due from our Related Parties. In addition, the Company generated deferred revenue balances from capital projects carried out on behalf of our Partner Airlines. Assets and liabilities expected to be realized within 12 months are classified as receivables—related parties and accounts payable and accrued and other liabilities—related parties, respectively, and other non-current assets—related parties and other non-current liabilities—related parties, respectively, for amounts expected to be realized thereafter. Substantially all of the Company’s revenues were derived from related parties during the years ended December 31, 2025, 2024, and 2023. Operating expenses incurred relate to aircraft rent expense, interrupted trip expenses, maintenance expense, and employee benefits, among others. Management has concluded that transactions of this nature were carried out on an arm’s-length basis.
Risks and uncertainties—During the years ended December 31, 2025, 2024, and 2023, substantially all of the Company’s revenues were derived from capacity purchase agreements with the Partner Airlines. Termination of any of these capacity purchase agreements could have a material adverse effect on the Company’s financial position, results of operations, and operating cash flows.
Each of the Company’s Partner Airlines comprised the following receivables as of December 31, 2025 and 2024 and revenues for the years ended December 31, 2025, 2024, and 2023:

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]
Cybersecurity Risk Management and Strategy
Republic employs a risk-based strategy informed by guiding principles from industry standard cybersecurity and risk management frameworks, such as those published by the National Institute of Standards and Technology (“NIST”), as well as industry guidelines and best practices. This is not intended to imply that we meet any particular technical standards, specifications, or requirements; only that we use various NIST security standards, guidelines and best practices to identify, assess, and manage cybersecurity risks relevant to our business.
As part of our risk-based strategy, Republic maintains appropriate technical and organizational measures and regularly reviews the appropriateness of those controls based on changes to the technical or regulatory environment. Republic also regularly incorporates cybersecurity awareness training into employee communications, engagement and training activities. Republic participates in various information-sharing organizations to timely share and receive threat information, thereby improving the collective defense of the aviation sector. Republic regularly seeks opportunities to improve its capabilities, including through cybersecurity trainings and skill development programs.
Republic utilizes a variety of third parties in connection with its cybersecurity risk management and also utilizes third-party cybersecurity companies to add capacity or expertise when necessary. Additionally, assessments of Republic’s cybersecurity program are periodically conducted by independent third-party assessors.
Republic is subject to cybersecurity risks related to its business partners and third-party service providers. In addition, cybersecurity considerations affect the selection and oversight of third-party service providers. We perform diligence on third parties, particularly those that have access to our systems, data or facilities that house such systems or data, and continually monitor cybersecurity threat risks identified through such diligence. A significant data breach may adversely affect Republic’s business. To manage these risks, we conduct evaluations of key suppliers based on risk and seek to incorporate appropriate security standards to manage the risk. Republic also regularly monitors the external cybersecurity posture of select third parties through various service providers.
Republic and its suppliers strive to design and implement technical and organizational controls comprehensively, consistently, and effectively as intended to protect the confidentiality, integrity or availability of systems and data. However, because Republic utilizes a risk-based strategy, based on professional judgment and analysis of the risks, it is possible that Republic may underappreciate or not recognize a specific risk. Moreover, even the best designed and implemented security controls may not eliminate the occurrence of cybersecurity incidents.
Our processes for assessing, identifying and managing material risks from cybersecurity threats is incorporated into our Enterprise Risk Management (“ERM”) framework. Our information security and ERM teams coordinate to regularly review and assess these risks using a wide range of tools and services.
Enterprise-wide training is a vital component to reducing risk and protecting customers, employees and company information. We expect all employees and third-party contractors to adhere to information security and privacy policies as they handle corporate and customer information in their daily jobs. To support this expectation, we require all employees and contractors with access to Republic information to complete annual training, which is updated as new technology, security and privacy issues emerge.
We regularly test our incident response processes through table-top exercises to ensure they continue to be effective as our business and the cybersecurity threat landscape evolve. Our incident response processes are designed to guide the actions we take to prepare for, detect, respond to and recover from cybersecurity incidents.
In the last three years at the time of this filing, we have not experienced any material cybersecurity incidents nor have we identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected us, including our operations, business strategy, results of operations, financial condition, or the price of our common stock.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)
 12 Months Ended
Dec. 31, 2025
Accounting Policies [Abstract]  
Basis of presentation Basis of presentation—The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts of Republic Airways Holdings Inc. and its wholly-owned subsidiaries. Beginning November 25, 2025 and in conjunction with the Merger, the consolidated financial statements include the accounts of Mesa Air Group, Inc. and its wholly-owned subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. Certain prior year balances have been reclassified to conform to current year presentation, including additional captions for Other current assets — related party and Stock-based compensation expense on the accompanying financial statements. Also, s
Use of estimates
Use of estimates—The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the carrying amounts of assets and liabilities, reported amounts of revenues and expenses, and the related disclosures thereto as of and during the periods presented, which management reassesses and evaluates on an ongoing basis. Significant estimates include but are not limited to (i) revenue recognition, (ii) estimated useful lives and residual values of aircraft and equipment, (iii) provision for income taxes, (iv) estimated fair value assumptions supporting the fair value of certain investments, put options, and warrants, and (v) provisional estimated fair value assumptions used to determine the fair values of assets acquired and liabilities assumed in the Merger in conjunction with the application of the acquisition method of accounting for business combinations under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations. See Note 3, Merger with Mesa Air Group, Inc. In addition, based on the nature of the CPA relationships, the Company estimates operating costs for certain reimbursable pass-through charges and records revenues based on these estimates. Actual results could materially differ from our initial estimates.
Cash, cash equivalents and restricted cash
Cash, cash equivalents and restricted cash—Cash and cash equivalents consists of cash on-hand and short-term, highly liquid investments with maturities of three months or less when acquired. Substantially all of our cash on-hand is held with six financial institutions. Restricted cash primarily includes cash in escrow to secure letters of credit issued for workers’ compensation claim reserves, construction activities, student loan guarantees, and deposits with various airport authorities.
Investments
Investments—The Company holds investments in debt and equity securities, stock warrants and put options, and equity method investments. Investments classified as marketable securities relate primarily to U.S. Treasury securities and are recorded to marketable securities in the consolidated balance sheets. The Company designates securities as trading, available-for-sale, or held-to-maturity, as applicable, at the time of acquisition and are subsequently measured at fair value or amortized cost at each reporting date. All of the Company’s investments in marketable securities were held for trading purposes during the years ended December 31, 2025, 2024, and 2023, and as a result, realized and unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations, representing Level 1 fair value measurements as defined in FASB ASC 820, Fair Value Measurement.
Non-current investments are investments with maturities greater than 12 months, described below, or investments which management of the Company intends to hold for a period greater than 12 months. Non-current investments are subject to provisions of FASB ASC 321, Investments, and are recorded to other non-current assets in the consolidated balance sheets at their acquisition date fair value and subsequently measured to fair value at each reporting date. Non-current investments are Level 1 fair value measurements as defined in the FASB ASC 820, Fair Value Measurement, fair value hierarchy. Realized and unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations.
The Company is additionally a warrant holder for stock warrants issued to certain initial investors in conjunction with our strategic partnership with EVE Holdings Inc. (“EVE”) for the development of electric vertical takeoff and landing (“eVTOL”) aircraft, exercisable through May 2027. Also related to our strategic relationship with EVE, the Company holds a put option attached to shares held in EVE equity that is exercisable on demand through May 2032. Stock warrants and the put option are characterized as financial instruments and are initially recorded and subsequently measured to fair value at each reporting date. Such amounts are recorded to other non-current assets in the consolidated balance sheets. Unrealized gains and losses are recorded to investment income and other, net in the consolidated statements of operations.
Equity method investments are initially measured at cost and subsequently adjusted for the Company’s proportionate share of income or loss of the investee and recorded to other non-current assets in the consolidated balance sheets in accordance with FASB ASC 323, Investments—Equity Method and Joint Ventures. The Company’s portion of income or loss generated by these investments are included as part of investment income and other, net in the consolidated statements of operations. The Company routinely monitors its investments for factors that may indicate a potential decline in value that is other than temporary.
Fair value of financial instruments
Fair value of financial instruments—The Company measures cash and cash equivalents, restricted cash, debt and equity securities, warrants, and put options at fair value on a recurring basis. Fair value, which is defined as an exit price related to the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, is measured using a combination of valuation practices as follows, as applicable:
Market approach—a valuation technique using prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities (or groups of assets and liabilities).
Income approach—valuation approach which converts future amounts to a single current (discounted) amount and is determined on the basis of the value indicated by current market expectations about those future amounts.
The Company classifies its fair value measurements based on the fair value hierarchy defined in ASC 820, Fair Value Measurement, which prioritizes the inputs used in determining fair value as follows:
Level 1    Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2    Quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active.
Level 3    Unobservable inputs for the asset or liability.
Inventories Inventories—Inventories consist of spare aircraft parts and supplies, which are charged to expense as consumed in the Company’s operations. Aircraft inventory is stated at weighted average cost at the lower of cost or its net realizable value. Inventory valuation adjustments are recorded to maintenance and repair expense in the consolidated statements of operations.
Assets held for sale Assets held for sale—The Company classifies assets as held for sale when (i) management commits to a plan to sell the asset; (ii) the asset is available for immediate sale in its present condition, subject only to terms that are usual and customary for sales of such assets; (iii) an active program to locate a buyer and other actions required to complete the plan to sell the asset has been initiated; (iv) the sale of the asset is probable, and transfer of the asset is expected to occur within one year, among other conditions. Assets designated as held for sale are recorded to other current assets in the consolidated balance sheets at the lower of their current carrying values or their fair market values, less costs to sell, beginning in the period in which the assets meet the criteria to be classified as held for sale.
Property and equipment
Property and equipment—The Company records property and equipment at its historical cost, less accumulated depreciation, which is charged to expense on a straight-line basis over the estimated useful life of the related asset. Effective January 1, 2024, the Company adjusted the estimated useful life of certain aircraft, rotable spare parts, and engines from 22.0 to 26.0 years to more closely align with market data impacting our fleet usage pattern. The change in accounting estimate decreased depreciation and amortization expense by $50.5 million for the year ended December 31, 2024 on then-current fleet assets. Estimated useful lives and residual values for each asset class are as follows:
Asset Class
Current Useful
Life Effective

Management reviews asset groups for impairment when events and business circumstances indicate carrying values of assets may not be recoverable. In such circumstances, management evaluates undiscounted cash flows expected to be generated by the respective asset group in comparison to its carrying value. Impairment charges, if any, are measured based on the excess carrying value over estimated fair value of the asset group.
Goodwill
Goodwill—Goodwill represents the excess of consideration exchanged over the fair value of identifiable assets acquired and liabilities assumed in conjunction with a business combination. Goodwill is initially recognized to comply with ASC 805, Business Combinations. Goodwill is assigned to the relevant reporting unit and is reviewed at least annually on October 31, or more frequently, if conditions indicate the carrying value of goodwill may not be recoverable to comply with provisions of ASC 350, Intangibles – Goodwill and Other.
Manufacturer incentives Manufacturer incentives—The Company’s aircraft and original equipment manufacturers periodically provide credits and rebates toward aircraft and equipment part purchases. Incentives associated with aircraft and equipment are applied as a reduction to the aircraft and equipment purchase price upon delivery, effectively reducing depreciation expense on a straight-line basis over aircraft and engine useful lives
Income taxes Income taxes—The Company accounts for income taxes using the asset and liability method. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in future years in which those temporary differences are expected to be recovered or settled. The measurement of deferred tax assets is adjusted by a valuation allowance, if necessary, to recognize future tax benefits to the extent that it is more likely than not they will be realized based on available evidence. The Company establishes liabilities for uncertain positions taken or expected to be taken in income tax returns, using a more-likely-than-not recognition threshold.
Aircraft maintenance and repair
Aircraft maintenance and repair—Aircraft maintenance and repair charges, including line maintenance, routine overnight maintenance, auxiliary power units, and airframe and engine overhaul are accounted for using the direct expense method.
In addition, the Company enters into long-term maintenance agreements that fix certain costs related to engines and other airframe components. Risks associated with these arrangements have been transferred to maintenance providers, and therefore, corresponding maintenance charges are recognized as power-by-the-hour contracts at a level rate per hour, subject to customary minimum utilization requirements.
Mezzanine equity Mezzanine equity—During the year ended December 31, 2020, the Company adopted the 2020 Omnibus Incentive Plan in which restricted stock units (“RSUs”) were issued to members of the Board of Directors and key members of management. RSUs are conditionally redeemable upon the occurrence of events that are not solely within control of the issuer of the securities. As such, RSUs are classified as mezzanine (temporary) equity as to convey that these shares may not have a permanent equity classification.
Shareholders' equity
Shareholders’ equity—Shareholders’ equity consists of preferred stock, par value $0.001, 500,000,000 shares authorized and no shares issued or outstanding as of December 31, 2025 and 2024; common stock, par value $0.001, 5,000,000,000 shares authorized, 45,713,286 shares and 38,993,300 shares issued and outstanding, respectively, as of December 31, 2025 and 2024. Additional paid-in capital consists of capital amounts contributed in excess of par value.
In conjunction with the Merger, Mesa Air Group, Inc. effectuated a 15-for-1 reverse stock split (the “Reverse Stock Split”). Further, in conjunction with the Merger closing, the Company received 38.9933 shares of common stock of legacy Mesa Air Group in exchange for and cancellation of each outstanding share of legacy Republic Airways common stock immediately prior to the Merger (the “Exchange”). Presentation of shareholders’ equity as of December 31, 2025 and 2024 retrospectively applies the Reverse Stock Split and the Exchange to consistently conform and to comply with the relevant provisions of ASC 505, Shareholders’ Equity.
U.S. Treasury Warrants
U.S. Treasury Warrants—In 2020 and 2021, in connection with the Coronavirus Aid, Relief, and Economic Security Act of 2020 (the “CARES Act”) payroll support program (“PSP”) and extensions, the Company issued to the U.S. Treasury warrants (the “U.S. Treasury Warrants”) to purchase shares of the Company’s common stock under the Payroll Support Programs and Secured Loans (“PSP Loan”). The warrants have a five-year term from the date of issuance. The weighted average grant-date fair value of these warrants was estimated using the Black-Scholes option pricing model. The current holder of the warrants exercised 315,534 warrants during the year ended December 31, 2025. The Company settled the exercise through net cash disbursements totaling $1.1 million to the holder. As of November 25, 2025, the U.S. Treasury Warrants were reclassified from liability awards to equity awards upon the closing of the Merger as the Company may elect a cash or net share settlement. Prior to the Merger, as the Company’s common stock was not listed on a national securities exchange, the Company was required to net cash settle. As of December 31, 2025, the Company had 691,701
warrants issued and outstanding. On January 30, 2026, the Company adopted the Omnibus Amendment with the U.S. Treasury to settle the outstanding U.S. Treasury Warrants as of December 31, 2025 in cash. The U.S. Treasury Warrants were settled on February 18, 2026 totaling $5.3 million. As of February 18, 2026, the Company has no remaining warrants outstanding. The Company did not issue any warrants for the years ended December 31, 2025 and 2024.
Measurement of U.S. Treasury Warrants represents a Level 3 fair value measurement within the fair value hierarchy as defined by ASC 820, Fair Value Measurement. Fair value adjustments are recorded to investment income and other, net in the consolidated statements of operations.

Basic net income per common share is computed by dividing net income attributable to the Company by the weighted average number of common shares outstanding during the period. The number of incremental shares from the assumed issuance of shares relating to restricted stock units and the exercise of warrants (excluding warrants with a nominal conversion price) is calculated by applying the treasury stock method. 344,237 weighted-average shares have been excluded from the calculation of diluted net income per common share for each period presented, as the related performance conditions have not been met.
Segment information
Segment information—The Company is organized and operates as one operating and reportable segment: regional airline services. Substantially all of the Company’s revenues are derived from customers within the United States.
This determination is based on the management approach which designates internal information regularly available to the Chief Operating Decision Maker (“CODM”) for making decisions and assessing performance as the source of determination of the Company’s reportable segments. The Company’s CODM, the Chief Executive Officer, reviews financial information presented on a consolidated basis for the purpose of making operating decisions and assessing financial performance.
The accounting policies of the one reportable segment are the same as those described in the summary of significant accounting policies. The CODM uses income before income taxes, as reported in our consolidated statements of operations, to measure segment profit or loss, assess performance, and make strategic capital resources allocations. The measure of segment assets is reported on our consolidated balance sheets as total assets. The significant expense categories regularly provided to the CODM are the expenses as presented on the consolidated statements of operations.
Recent accounting pronouncements
Recent accounting pronouncements—In December 2023, the FASB issued ASU 2023-09—Improvement to Income Tax Disclosures (Topic 740), to provide clarifying guidance on the transparency of income tax disclosures. ASU 2023-09 is effective for public entities for annual reporting periods beginning after December 15, 2024. The Company adopted ASU 2023-09 on December 31, 2025 and applied the new disclosure requirements retroactively. Prior period disclosures have been adjusted to reflect the new disclosure requirement. The impact of the implementation to the
consolidated financial statements and related disclosures was not material. See Note 11, Income Taxes in the accompanying notes to the consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to provide investors with more granular detail on cost of sales, and selling, general, and administrative expenses. ASU 2024-03 is effective for public entities for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.
In May 2025, the FASB issued ASU 2025-03—Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity, which revises the guidance in ASC 805, Business Combinations, on identifying the accounting acquirer in a business combination in which the legal acquiree is a variable interest entity (“VIE”). ASU 2025-03 is effective for public entities with fiscal years beginning after December 15, 2026 with early adoption permitted. The Company early adopted ASU 2025-03 on January 1, 2025, and the impact of the implementation to the consolidated financial statements was not material.
In September 2025, the FASB issued ASU 2025-06—Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to improve the guidance related to the capitalization of software development costs. ASU 2025-06 is effective for public entities for fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.
In December 2025, the FASB issued ASU 2025-11—Interim Reporting (Topic 270): Narrow Scope Improvements, which clarifies the current requirements under Topic 270. The ASU provides a comprehensive list of required interim disclosures and requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for public entities for interim periods in fiscal years beginning after December 15, 2027 with early adoption permitted. The Company is currently evaluating the impact the standard will have to the consolidated financial statements and related disclosures.
Revenue
The Company accounts for contracts with our Partner Airlines under ASC 606, Revenue from Contracts with Customers, and ASC 842, Leases, as applicable, when each party has committed to perform under the contract, each party’s rights and payment terms have been established, when the contract has commercial substance, and when collectability of amounts due under the contract is probable. Under CPAs with our Partner Airlines, the Company has
committed to perform various flight services and maintenance activities classified as regional jet services. Within regional jet services, flight services represent a series of distinct activities accounted for as a single performance obligation satisfied over time as flights are completed. The Company recognizes certain maintenance activities as separate performance obligations, which are satisfied as the related distinct service is complete. Substantially all of the Company’s revenues are generated from regional jet services.
Revenues associated with regional jet services are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred and a fixed rate for available-to-schedule aircraft, payable on a monthly basis; and (ii) a premium amount which is earned monthly and quarterly by maintaining minimum aircraft utilization levels and exemplary operating results. To the extent that minimum targets are not achieved, the Company could be subject to financial penalties. These fixed-fee rates are contractually subject to periodic economic adjustment. The Company additionally receives reimbursement from our Partner Airlines for direct expenses incurred such as qualifying maintenance activities, property taxes, and miscellaneous operating expenses. Certain charges such as fuel, landing fees, and certain ownership costs are generally paid directly by the Partner Airlines, although the charges were incurred by the Company in ongoing operations. The Company refers to these charges as “Partner direct charges.” Pass-through charges are primarily recorded to revenues and the corresponding operating expense on a gross basis. Pass-through charges recorded on a net basis are not material.
Amounts recognized as regional jet services revenues are measured at the contractual amount the Company expects it will be entitled to in exchange for the promised services. The Company allocates the transaction price as flights are completed with variable consideration that relates specifically to the Company’s efforts in delivering each flight recognized in the period in which the individual flight is completed and measured on a monthly basis. The Company records an estimate for incentive revenue based on our expected performance at the end of each period. These estimates are derived under accounting guidance related to variable consideration constraints and based on amounts expected to be collected. The Company has concluded that allocating the variability directly to individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that generally follows the variable amounts billed from the Company to Partner Airlines. As allowed with ASC 606, the Company has elected to apply practical expedients to expense significant financing components and the incremental costs of obtaining a contract as incurred.
A portion of the Company’s compensation under its CPAs is designed to reimburse the Company for certain aircraft ownership costs. The Company has concluded that a component of its revenue under the CPAs is deemed to be embedded lease revenue and as such, agreements identify the right-of-use of a specific type and number of aircraft over the term of the CPA. Embedded lease revenue associated with the Company’s CPAs is accounted for as an operating lease under ASC 842, Leases.
Amounts recognized as revenues in the consolidated statements of operations are subject to certain estimates, which could materially impact the timing and consideration determined under the contract. Such estimates include (i) expected contract terms from material modifications to the fixed-fee capacity purchase agreements which are expected to be made in the future and (ii) the extent to which disputes in contract interpretation arise.
Receivables and contract assets—Receivables represent a right to consideration for promised services which have been transferred to customers. The Company records provisions for credit losses using an expected credit losses model on the basis of specific identification and historical collection experience. For more information on credit losses, refer to Note 17, Valuation and Qualifying Accounts.
Contract assets are generated from the partial satisfaction of certain performance obligations, generally related to the delivery of aircraft maintenance services, under customer contracts whereby the Company has the right to consideration for services transferred or provided to its customers. Other current assets—related parties and other non-current assets—related parties in the consolidated balance sheets consist entirely of contract assets, which have been appropriately reduced for the applicable financing component. The Company expects to collect all current amounts within the next twelve months, while non-current amounts will be collected over the period from 2027 to 2030.
Contract liabilities—Contract liabilities consist of deferred revenues for which the Company has received customer payment for undelivered services. In addition, the Company periodically carries out capital projects on behalf of its Partner Airlines, generally pertaining to aircraft fleet and livery improvements. Revenues of this nature are recognized over time, depicting the pattern of transfer of control of services, resulting in ratable recognition of revenues over the remaining term of the CPA, ranging from 2026 - 2036.
Current and non-current deferred revenues are recorded to accounts payable and accrued and other liabilities-related parties and other non-current liabilities-related parties, respectively, in the consolidated balance sheets. The Company recognized $16.1 million, $13.7 million, and $10.8 million of the deferred revenue to revenues in the consolidated statements of operations during the years ended December 31, 2025, 2024, and 2023, respectively, which was previously included in contract liabilities at December 31, 2024, 2023, and 2022, respectively. Current contract liabilities were $35.9 million and $22.7 million as of December 31, 2025 and 2024, respectively. Non-current contract liabilities were $103.2 million and $41.8 million as of December 31, 2025 and 2024, respectively.
Lease Revenue
The Company accounts for contracts with our Partner Airlines under ASC 606, Revenue from Contracts with Customers, and ASC 842, Leases, as applicable, when each party has committed to perform under the contract, each party’s rights and payment terms have been established, when the contract has commercial substance, and when collectability of amounts due under the contract is probable. Under CPAs with our Partner Airlines, the Company has
committed to perform various flight services and maintenance activities classified as regional jet services. Within regional jet services, flight services represent a series of distinct activities accounted for as a single performance obligation satisfied over time as flights are completed. The Company recognizes certain maintenance activities as separate performance obligations, which are satisfied as the related distinct service is complete. Substantially all of the Company’s revenues are generated from regional jet services.
Revenues associated with regional jet services are generally derived from (i) a fixed fee per departure, flight hour, and/or block hour of time incurred and a fixed rate for available-to-schedule aircraft, payable on a monthly basis; and (ii) a premium amount which is earned monthly and quarterly by maintaining minimum aircraft utilization levels and exemplary operating results. To the extent that minimum targets are not achieved, the Company could be subject to financial penalties. These fixed-fee rates are contractually subject to periodic economic adjustment. The Company additionally receives reimbursement from our Partner Airlines for direct expenses incurred such as qualifying maintenance activities, property taxes, and miscellaneous operating expenses. Certain charges such as fuel, landing fees, and certain ownership costs are generally paid directly by the Partner Airlines, although the charges were incurred by the Company in ongoing operations. The Company refers to these charges as “Partner direct charges.” Pass-through charges are primarily recorded to revenues and the corresponding operating expense on a gross basis. Pass-through charges recorded on a net basis are not material.
Amounts recognized as regional jet services revenues are measured at the contractual amount the Company expects it will be entitled to in exchange for the promised services. The Company allocates the transaction price as flights are completed with variable consideration that relates specifically to the Company’s efforts in delivering each flight recognized in the period in which the individual flight is completed and measured on a monthly basis. The Company records an estimate for incentive revenue based on our expected performance at the end of each period. These estimates are derived under accounting guidance related to variable consideration constraints and based on amounts expected to be collected. The Company has concluded that allocating the variability directly to individual flights results in an overall allocation meeting the objectives in ASC 606. This results in a pattern of revenue recognition that generally follows the variable amounts billed from the Company to Partner Airlines. As allowed with ASC 606, the Company has elected to apply practical expedients to expense significant financing components and the incremental costs of obtaining a contract as incurred.
A portion of the Company’s compensation under its CPAs is designed to reimburse the Company for certain aircraft ownership costs. The Company has concluded that a component of its revenue under the CPAs is deemed to be embedded lease revenue and as such, agreements identify the right-of-use of a specific type and number of aircraft over the term of the CPA. Embedded lease revenue associated with the Company’s CPAs is accounted for as an operating lease under ASC 842, Leases.
