Mesa Air Group Reports 4th Quarter and Fiscal 2004 Earnings

PHOENIX, November 22, 2004 – Mesa Air Group, Inc. (NASDAQ-MESA) today announced fourth quarter after tax earnings of $10.7 million on revenues of $260.0 million, or 28 cents per share on a diluted basis (all amounts reported herein are after tax, reflect a restatement of prior year amounts and all per share amounts reported hereafter are on a diluted basis). Net income was $9.9 million or 25 cents per share for the same period of fiscal 2003. Pro forma net income for the quarter was $11.5 million, or 30 cents per share. Pro forma net income excluded the tax effects of $0.9 million relating to the second quarter one-time compensation payments, net investment losses of $0.4 million, the reversal of certain failed merger related costs of $0.2 million and the reversal of certain restructuring liabilities of $0.2 million. This compares to pro forma earnings of $9.7 million on revenues of $175.5 million, or 25 cents per share for the comparable period of fiscal 2003.

Year-to-date earnings, including restated amounts for the first quarter of fiscal 2004, were $26.3 million on revenues of $896.8 million, or 70 cents per share. 2003 year-to-date earnings were $25.3 million on revenues of $600.0 million, or 76 cents per share. Including pro forma adjustments of $12.8 million, year-to-date earnings would have been $39.1 million, or $1.00 per share. Pro forma net income excludes the costs to terminate the leases of seven Beechcraft 1900D aircraft of $7.2 million, one-time compensation payments of $4.2 million and related tax effects, net failed merger related costs of $2.0 million, the reversal of certain restructuring liabilities of $0.2 million and investment income of $0.3 million. This compares to pro forma earnings of $20.5 million, or 62 cents per share, for the comparable period of fiscal 2003.

As of September 30, 2004, the Company’s cash, marketable securities and debt investments were approximately $241.1 million, including $9.5 million of restricted cash, compared to $166.1 million as of September 30, 2003. During the fourth quarter, the Company continued its regional jet expansion by adding five regional jets to its current fleet. These deliveries increased Mesa’s fleet of regional jets to 129 regional jet aircraft, comprised of 90 50-seat regional jets, 15 70-seat regional jets and 24 86-seat regional jets. Subsequent to quarter end, the Company received two additional CRJ-200s and one CRJ-900 aircraft bringing the number of regional jets in the fleet to 132. In addition, the Company permanently financed five CRJ-900s which had been on interim financing. The Company currently has five CRJ-900s on interim financing. During the remainder of fiscal 2005, the Company is contractually committed to delivering to our partners a minimum of 13 86-seat regional jets.

On September 12, 2004, US Airways, which represented approximately 35% of the Company’s 4th quarter revenues, filed a petition for Chapter 11 bankruptcy protection. Unpaid amounts related to pre-petition obligations, net of any amounts owed by the Company to US Airways, were less than $3 million and the Company believes it is adequately reserved. The Company has been paid for all amounts due post petition in accordance with contractual terms and continues to operate its normal flight schedule. In addition, the Company has developed a number of contingency plans to address potential outcomes of US Airways’ bankruptcy.

During the quarter ended September 30, 2004, the Company repurchased approximately 1.5 million shares of its outstanding common stock. During October, the Company’s Board of Directors authorized the repurchase of up to an additional 2 million of the Company’s outstanding shares of its common stock. The Company has bought approximately 6.3 million

shares of common stock under the repurchase programs first approved by the Board in December 1999.

In August and November the Company closed on its agreement with LogisTechs, Inc., a wholly-owned affiliate of GE Capital Aviation Services (GECAS), for the management and repair of its CRJ 200 aircraft rotable spare parts inventory. Under the agreement, LogisTechs financed approximately $21 million in existing spare parts inventory and committed to finance $4 million of additional spare parts to support Mesa’s CRJ-200 fleet. The Company is currently negotiating similar agreements for up to $43 million of spare parts for Mesa’s current and to be delivered fleet of Bombardier CRJ 700/900 and current fleet of Embraer 145, representing $31 million of our existing inventory and forgone purchases of $12 million.

In addition, during October the Company entered into an agreement to lease four (4) Raytheon Beech 1900D aircraft operated by its subsidiary, Air Midwest, Inc., to Gulfstream International Airlines, a regional turboprop air carrier based in Ft. Lauderdale, Florida. These aircraft and three other Beech 1900s will be taken out of the Company’s Florida operations. These actions are in furtherance of the Company’s vigorous pursuit of reducing unprofitable 19-seat flying in markets that do not have government subsidizes through the Essential Air Service program. We believe this consolidation will positively impact Air Midwest’s profitability and improve our ability to provide the best service possible throughout the remainder of our turboprop network.

“This quarter marks our most profitable quarter since September 2000,” said Jonathan Ornstein, Mesa’s Chairman and CEO. “This accomplishment is particularly notable given the current state of the airline industry and a testament to the success of our revenue guarantee business model. While we recognize the importance of our airline partners to our success and are cognizant of the challenges they face, given the recent decline in fuel prices and our partners’ significantly lower cost structures, we are becoming more optimistic. While there has been some talk recently of a potential oversupply of smaller regional jets, given the difficulty we have experienced in sourcing such aircraft to meet our partners’ needs, as well as currently announced future regional jet requirements of the major airlines, we do not believe this to be the case. We feel any oversupply will prove to be temporary and as a result of our low cost structure, will not significantly impact Mesa long term. In addition, we are looking at a number of acquisition and investment opportunities. While we will undoubtedly face challenges going forward, we believe the Company, with over $230 million in liquidity, is well positioned financially to take advantage of potential opportunities. We continue to focus on providing the highest level of operational integrity to our partners and passengers and consolidating our recent growth. Our people have done a wonderful job and we thank them for their extraordinary contribution to our current success. Lastly, it is with great sorrow that we recognize the passing of our Founder and former Chairman and CEO, Larry L. Risley. He will be greatly missed.”

To supplement our consolidated financial statements presented in accordance with GAAP, the Company uses non-GAAP measures of pro forma net income and pro forma earnings per share, which are adjusted from our GAAP results as shown above. These non-GAAP adjustments are provided to enhance the user’s overall understanding of our current financial performance. We believe the non-GAAP results provide useful information to both management and investors by excluding certain charges and other amounts that we believe are not indicative of our core operating results. These non-GAAP measures are included to provide investors and management with an alternative method for assessing the Company’s operating results in a manner that is focused on the performance of the Company’s ongoing operations and to provide a more consistent basis for comparison between quarters. In addition, since we have historically reported pro forma results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting. These measures are not in accordance with or an alternative for, GAAP and may be different from pro forma measures used by other companies.

At September 30, 2004, the conversion features of the Company’s senior convertible notes due 2024 had not been met and therefore the dilutive effect of the notes was not included in the determination of earnings per common share. Diluted income per share would have been $0.25 and pro forma diluted income per share would have been $0.27 for the three months ended September 30, 2004 if the dilutive effect of the notes were to be included in the computation of income per common share.
