Accounting Policies [Abstract] |
Basis of presentation | Basis of presentation—The accompanying condensed 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 condensed 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 parties and executive separation and Merger-related items.
U.S. Treasury Warrants | U.S. Treasury Warrants—In 2021 and 2022, 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”). As of December 31, 2025, the Company had 691,701 warrants issued and outstanding which were settled for $5.3 million during the three months ended March 31, 2026. Therefore, as of March 31, 2026, the Company has no remaining warrants outstanding.
Net Income per common share | Net income per common share—Basic and diluted net income per common share were as follows:
| Three Months Ended
(in millions, except share and per share data) | March 31, 2026 |  | March 31, 2025
Numerator: |  |  |
Net income | $ | 26.9 |  |  | $ | 27.1 |
Denominator: |  |  |
Weighted-average common shares outstanding - basic | 45,652,671 |  |  | 39,096,437 |
Dilutive effects of unvested shares | 304,946 |  |  | 696,398 |
Dilutive effects of U.S. Treasury Warrants | 96,829 |  |  | — |
Adjusted weighted-average common shares outstanding - diluted | 46,054,446 |  |  | 39,792,835 |
Net income per common share: |  |  |
Basic | $ | 0.59 |  | $ | 0.69
Diluted | $ | 0.58 |  | $ | 0.68
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 unvested shares and the exercise of warrants (excluding warrants with a nominal conversion price) is calculated by applying the treasury stock method. A total of 821,398 potentially dilutive 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 condensed 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 condensed consolidated balance sheets as total assets. The significant expense categories regularly provided to the CODM are the expenses as presented on the condensed consolidated statements of operations.
Recent accounting pronouncements | Recent accounting pronouncements— 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 condensed consolidated financial statements and related disclosures. 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 condensed 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 condensed 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 condensed 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. 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 condensed 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 April 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 to 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 condensed consolidated balance sheets. The Company recognized $12.0 million and $3.8 million of the deferred revenue to revenues in the condensed consolidated statements of operations during the three months ended March 31, 2026 and 2025, respectively, which was previously included in contract liabilities at December 31, 2025 and 2024, respectively. Current contract liabilities were $35.0 million and $35.9 million as of March 31, 2026 and December 31, 2025, respectively. Non-current contract liabilities were $97.3 million and $103.2 million as of March 31, 2026 and December 31, 2025, 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.
