Mesa Air Group Reports Second Quarter Fiscal 2024 Results

June 18, 2024

PHOENIX, June 18, 2024 – Mesa Air Group, Inc. (NASDAQ: MESA) (“Mesa” or the “Company”) today reported second quarter fiscal 2024 financial and operating results.

Second Quarter Fiscal 2024 Update:

•Total operating revenues of $131.6 million

•Pre-tax income of $11.7 million, net income of $11.7 million or $0.28 per diluted share

•Adjusted net income of $6.3 million or $0.15 per diluted share

•Adjusted EBITDAR1 of $28.2 million

•Flew 99.85% controllable completion factor

Additional Updates:

•Closed on additional five engines associated with RASPRO finance lease since June 2024 announcement

•Renegotiated operating lease on two CRJ aircraft into a fully amortized buyout lease, reducing payments by $9.5 million over life of lease

“Our second quarter results have begun to demonstrate an improvement in our business and reflect our efforts over the past year-and-a-half to restructure and strengthen our operations, P&L, and balance sheet,” said Jonathan Ornstein, Chairman and CEO. “Given meaningfully improved block-hour rates on our E-175 flying, coupled with our initiatives to eliminate surplus CRJ assets, we achieved our first GAAP and adjusted net profits in 11 quarters, as well as our best adjusted EBITDAR result over that period. Concurrently, Mesa has reduced its total debt by $221.5 million, or 36%, over the past year.

“While we still have work to do as we transition out of our CRJ-900 fleet and build our E-175 flying, we expect to remain cash-flow neutral for the remainder of the fiscal year. With an optimized asset base, our ongoing transition toward higher-margin E-175 flying, and the continued reduction in pilot attrition and strength in our pilot pipeline, we look forward to returning to consistent profitability in the future.”

Second Quarter Fiscal 2024 Details

Total operating revenues in Q2 2024 were $131.6 million, an increase of $9.7 million, or 8.0%, from $121.8 million for Q2 2023. Contract revenue decreased $10.0 million, or 9.7%. These increases were primarily driven by higher E-175 block-hour rates with United Airlines, effective as of October 1, 2023. Mesa recognized the increased rates for Q2 2024, as well as an additional $8.8 million for Q1 2024, in this quarter. Pass-through revenue decreased by $0.3 million, or 1.6%. Mesa’s Q2 2024 results include, per GAAP, the recognition of $7.9 million of previously deferred revenue, versus the deferral of $5.7 million in Q2 2023. The remaining deferred revenue balance of $10.2 million will be recognized as flights are completed over the remaining term of the United contract.

Total operating expenses in Q2 2024 were $119.9 million, a decrease of $28.8 million, or 19.3%, versus Q2 2023. This decrease primarily reflects $14.1 million lower asset impairment losses, $6.7 million lower depreciation and amortization expense, and $5.5 million, or 10.0% lower, flight operations expense, driven by Mesa’s divestiture of surplus CRJ assets.

Mesa’s Q2 2024 results reflect net income of $11.7 million, or $0.28 per diluted share, compared to a net loss of $35.1 million, or $(0.88) per diluted share, for Q2 2023. Mesa’s Q2 2024 adjusted net income was $6.3 million, or $0.15 per diluted share, versus an adjusted net loss of $21.3 million, or $(0.53) per diluted share, in Q2 2023.

Mesa’s adjusted EBITDA1 for Q2 2024 was $26.8 million, compared to adjusted EBITDA of $7.1 million for Q2 2023. Adjusted EBITDAR was $28.2 million for Q2 2024, compared to adjusted EBITDAR of $7.9 million in Q2 2023.

Second Quarter Fiscal 2024 Operating Performance

Operationally, the Company reported a controllable completion factor of 99.85% for United during Q2 2024. This is compared to a controllable completion factor of 99.63% for United during Q2 2023. Controllable completion factor excludes cancellations due to weather and air traffic control.

For Q2 2024, approximately 98% of the Company’s total revenue was derived from its contract with United. The Company’s CPA with United provides for 80 large (70/76 seats) jets, comprising a mix of E-175s and CRJ-900s. In Q2 2024, Mesa’s fleet mix comprised 56 E-175s and 24 CRJ-900s.

Balance Sheet and Cash Flow

Mesa ended the March quarter with $18.5 million in unrestricted cash and cash equivalents. As of March 31, 2024, the Company had $400.0 million in total debt, secured primarily with aircraft and engines, compared to a balance of $621.6 million as of March 31, 2023. During the quarter, the Company made $38.8 million of debt payments related to CRJ engine sale transactions, achieved $10.5 million in loan forgiveness from United as a result of operational performance, and had a net reduction of $7.6 million on its line of credit with United.

Reconciliation of non-GAAP financial measures

Although these financial statements are prepared in accordance with accounting principles generally accepted in the U.S. ("GAAP"), certain non-GAAP financial measures may provide investors with useful information regarding the underlying business trends and performance of Mesa's ongoing operations and may be useful for period-over-period comparisons of such operations. The tables below reflect supplemental financial data and reconciliations to GAAP financial statements for the three months ended December 31, 2023 and December 31, 2022. Readers should consider these non-GAAP measures in addition to, not a substitute for, financial reporting measures prepared in accordance with GAAP. These non-GAAP financial measures exclude some, but not all items that may affect the Company's net income or loss. Additionally, these calculations may not be comparable with similarly titled measures of other companies.
