      The accompanying unaudited, condensed consolidated financial statements of Mesa Air Group, Inc. (“Mesa” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for a complete set of financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results for the periods presented have been made. Operating results for the six-month period ended March 31, 2005, are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2005. These condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended September 30, 2004.
      The accompanying condensed consolidated financial statements include the accounts of Mesa Air Group, Inc. and its wholly-owned operating subsidiaries (collectively “Mesa” or the “Company”): Mesa Airlines, Inc. (“Mesa Airlines”), a Nevada corporation and certificated air carrier; Freedom Airlines, Inc. (“Freedom”), a Nevada corporation and certificated air carrier; Air Midwest, Inc. (“Air Midwest”), a Kansas corporation and certificated air carrier; MPD, Inc., a Nevada corporation, doing business as Mesa Pilot Development; Regional Aircraft Services, Inc.

2. Segment Reporting
      SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information,” requires disclosures related to components of a company for which separate financial information is available that is evaluated regularly by a company’s chief operating decision maker in deciding the allocation of resources and assessing performance. The Company has three airline operating subsidiaries, Mesa Airlines, Freedom Airlines and Air Midwest and various other subsidiaries organized to provide support for the Company’s airline operations. The Company has aggregated these operating subsidiaries into three reportable segments: Mesa Airlines, Air Midwest/ Freedom and Other. Mesa Airlines operates all of the Company’s regional jets and Dash-8 aircraft. Air Midwest and Freedom operate the Company’s Beech 1900 turboprop aircraft. The Other reportable segment includes Mesa Air Group, RAS, MPD, MAG-AIM, MAGI, Mesa Leasing, Inc. and Ritz Hotel Management Corp., all of which support Mesa’s operating subsidiaries. Prior to October 2004, the Company operated regional jets in both Mesa and Freedom. In October 2004, the Company completed its transition of regional jets from Freedom into Mesa and transferred a B1900D aircraft from Air Midwest into Freedom. As such, the Company has aggregated Freedom with Air Midwest beginning in the first quarter of fiscal 2005. Operating revenues in the Other segment are primarily sales of rotable and expendable parts to the Company’s operating subsidiaries.
      Mesa Airlines provides passenger service with regional jets under revenue-guarantee contracts with America West, United and US Airways. Mesa Airlines’ code-share agreement with Frontier terminated on December 31, 2003. Mesa Airlines also provides passenger service with Dash-8 aircraft under revenue-guarantee contracts with United and America West. As of March 31, 2005, Mesa Airlines operated a fleet of 152 aircraft — 100 CRJs, 36 ERJs and 16 Dash-8s.

3. Investments
      The Company has a cash management program which provides for the investment of excess cash balances primarily in short-term money market instruments, intermediate-term debt instruments and common equity securities of companies operating in the airline industry.
      SFAS No. 115, “Accounting for Certain Investments in Debt and Equity Securities,” requires that all applicable investments be classified as trading securities, available for sale securities or held-to-maturity securities. The Company currently has $124.0 million in marketable securities that include common equity securities of companies operating in the airline industry, US treasury notes and corporate bonds. These investments are classified as trading securities and accordingly, are carried at market value with changes in value reflected in the current period operations. Unrealized gains (losses) relating to trading securities held at March 31, 2005 and September 30, 2004, were ($1.0) million and ($1.7) million, respectively.
      The Company has determined that investments in auction rate securities (“ARS”) should be classified as short-term investments. Previously, such investments had been classified as cash and cash equivalents. ARS generally have long-term maturities; however, these investments have characteristics similar to short-term investments because at predetermined intervals, generally every 28 days, there is a new auction process. The balance of marketable securities at March 31, 2005 includes investments in ARS of $55.4 million. The Company reclassified ARS of $47.8 million as of September 30, 2004 that were previously included in cash and cash equivalents to short-term investments.
4. Restricted Cash
      At March 31, 2005, the Company had $10.3 million in restricted cash on deposit with two financial institutions. In September 2004, the Company entered into an agreement with a financial institution for a $9.0 million letter of credit facility and to issue letters of credit for landing fees, workers compensation insurance and other business needs. Pursuant to the agreement, $5.0 million of outstanding letters of credit at March 31, 2005 are collateralized by amounts on deposit. The Company also maintained $5.3 million on deposit with another financial institution to collateralize its direct deposit payroll obligations.
5. Accounts Receivable from Code-Share Partners
      The Company has code-share agreements with America West, US Airways, United and Midwest Airlines. Approximately 99% of the Company’s consolidated passenger revenue for the three months ended March 31, 2005, were derived from these agreements. Accounts receivable from the Company’s code-share

partners were 47% and 59% of total gross accounts receivable at March 31, 2005 and September 30, 2004, respectively.
6. Deferred Credits
      Deferred credits consist of aircraft purchase incentives provided by the aircraft manufacturers and deferred gains on the sale and leaseback of interim financed aircraft. These incentives include credits that may be used to purchase spare parts, pay for training expenses or reduce other aircraft operating costs. These deferred credits and gains are amortized on a straight-line basis as a reduction of lease expense over the term of the respective leases.
7. Short-Term Debt
      At March 31, 2005 and September 30, 2004, the Company had $277.5 million and $231.0 million, respectively, in notes payable for aircraft on interim financing. Under interim financing arrangements, the Company takes delivery and title to the aircraft prior to securing permanent financing and the acquisition of the aircraft is accounted for as a purchase with debt financing. Accordingly, the Company reflects the aircraft and debt under interim financing on its balance sheet during the interim financing period. These interim financing agreements are through November 30, 2005 and provide for monthly interest only payments at LIBOR plus three percent. Under the interim financing arrangements, the manufacturer has provided a portion of the financing with the remainder being provided by Export Development Canada (“EDC”). As part of the financing with the EDC, the Company is required to maintain a deposit of five percent of the aircraft value with the EDC. Pursuant to this requirement, the Company borrowed $13.2 million against its aircraft delivery deposits with the manufacturer and placed these funds on deposit with the EDC. Amounts on deposit will be returned to the manufacturer upon the earlier of payment in full of the interim financing or completion of permanent financing.
      The Company’s interim financing agreement with the manufacturer provides for the Company to have a maximum of 15 aircraft on interim financing at a given time. After taking delivery of the aircraft, it is the Company’s intention to subsequently enter into a sale-leaseback transaction with an independent third-party lessor when market lease rates permit. Upon permanent financing as a lease, the proceeds from the sale-leaseback transaction are used to retire the notes payable to the manufacturer. Any gain recognized on sale-leaseback transactions is deferred and amortized over the life of the lease.
      As of March 31, 2005, our growth strategy involves the acquisition of eight more Bombardier regional jets during the remainder of fiscal 2005. As of March 31, 2005, we had permanently financed 35 of the 45 CRJ-700 and CRJ-900 aircraft delivered under the 2001 BRAD agreement; the remaining aircraft are subject to interim financing. We may utilize interim financing provided by the manufacturer and have the ability to fund up to 15 aircraft at any one time under this facility. Our ability to obtain additional interim financing is contingent upon obtaining permanent financing for the aircraft already delivered. As of March 31, 2005, we are obligated under our code-share agreements to place an additional eight CRJ 900 regional jets over the next six months. We are currently in discussions with one of our code-share partners regarding the timing and delivery of the last three CRJ-900s on order. As of March 31, 2005, we have firm orders with Bombardier for an additional 15 regional jets.

9. Earnings Per Share
      The Company accounts for earnings per share in accordance with SFAS No. 128, “Earnings per Share.” Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the periods presented. Diluted net income per share reflects the potential dilution that could occur if outstanding stock options and warrants were exercised. In addition, dilutive convertible securities are included in the denominator while interest on convertible debt, net of tax, is added back to the numerator. A reconciliation of the numerator and denominator used in computing income per share is as follows:
                                 
    Three Months Ended   Six Months Ended

      In September 2004, the Emerging Issues Task Force (“EITF”) reached a consensus on EITF Issue No. 04-08, “The Effect of Contingently Convertible Debt on Diluted Earnings per Share.” EITF Issue No. 04-08 requires shares of common stock issuable upon conversion of contingently convertible debt instruments to be included in the calculation of diluted earnings per share whether or not the contingent conditions for conversion have been met, unless the inclusion of these shares is anti-dilutive. Previously, shares of common stock issuable upon conversion of contingently convertible debt securities were excluded from the calculation of diluted earnings per share if the contingency had not been met. The Company previously included its convertible notes due 2003 in the EPS calculation. The Company adopted the provisions of EITF Issue No. 04-08 in the first quarter of fiscal 2005, and as such, has now also included our 3.625% senior convertible notes due 2024 in the calculation of dilutive earnings per share. EITF Issue No. 04-08 requires the restatement of prior period diluted earnings per share amounts. Our 3.625% senior convertible notes due 2024 were issued in February 2004, thus our previously reported diluted earnings per share for the three and six months ended March 31, 2004 have been restated to include the dilutive impact of the 3.625% senior convertible notes. Our previously reported diluted earnings per share for the third and fourth quarters of fiscal 2004 will also be restated to include the dilutive impact of the 3.625% senior convertible notes.
10. Stock Repurchase Program
      In December 1999, the Company’s Board of Directors authorized the Company to repurchase up to approximately 3.4 million shares of the outstanding common stock of the Company. In January 2001, October 2002 and October 2004, the Company’s Board amended the original plan and authorized the repurchase of one million, two million and two million additional shares of common stock, respectively. As of March 31, 2005, the Company has acquired and retired approximately 6.8 million shares of its outstanding common stock at an aggregate cost of approximately $40.0 million leaving approximately 1.6 million shares available for purchase under the current Board authorizations. Purchases are made at management’s discretion based on market conditions and the Company’s financial resources. Subsequent to quarter end, the Board of Directors authorized the Company to purchase up to one million additional shares of the outstanding common stock of the Company.
      The Company repurchased the following shares for $1.5 million during the three months ended March 31, 2005:

11. Beechcraft 1900D Cost Reductions
      On February 7, 2002, the Company entered into an agreement with Raytheon Aircraft Credit Company (the “Raytheon Agreement”) to reduce the operating costs of its Beechcraft 1900D fleet. In connection with the Raytheon Agreement and subject to the terms and conditions contained therein, Raytheon agreed to provide up to $5.5 million in annual operating subsidy payments to the Company contingent upon satisfying certain spending requirements and, among other things, the Company remaining current on its payment obligations to Raytheon. The amount was subsequently reduced to $5.3 million as a result of a reduction in the

Company’s fleet of B1900D aircraft. Approximately $2.7 million was recorded as a reduction to expense during the six months ended March 31, 2005 and 2004.
      In return, the Company granted Raytheon an option to purchase up to 233,068 warrants at a purchase price of $1.50 per warrant. Each warrant entitles the holder to purchase one share of common stock at an exercise price of $10.00 per share. Each of the warrants is exercisable at any time over a three-year period following its date of purchase. At March 31, 2005, Raytheon has vested in and exercised its option to purchase all 233,068 warrants.
12. Interest Expense
      Included in interest expense on the statement of income was interest expense related to aircraft financing of $6.8 million and $2.8 million for the three months ended March 31, 2005 and 2004, respectively, and $12.7 million and $6.8 million for the six months ended March 31, 2005 and 2004, respectively.
13. Impairment of Long-Lived Assets
Shorts 360 Impairment
      The Company took a charge in fiscal 2002 to accrue for the remaining lease payments of two Shorts 360 aircraft and the future costs of returning these aircraft to the lessor. In January 2005, the Company entered into an agreement with the lessor for the early return of these two aircraft. The agreement included the elimination of the aircraft return conditions and called for a $1.3 million payment. As a result, the Company reduced its reserve for the costs to return these aircraft to the agreed upon amount at December 31, 2004.
      The changes in the impairment and restructuring charges for the periods ended March 31, 2005 and 2004 are as follows:

      The Company applies the provision of APB Opinion No. 25 and related interpretations in accounting for its stock-based compensation plans. Accordingly, no compensation cost has been recognized for awards made pursuant to its fixed stock option plans.

16. Commitments and Contingencies
      In May 2001, the Company entered into an agreement with Bombardier Regional Aircraft Division (“BRAD”) under which the Company committed to purchase a total of 15 CRJ-700s and 25 CRJ-900s. The transaction includes standard product support provisions, including training, preferred pricing on initial inventory provisioning, maintenance and technical publications. As of March 31, 2005, the Company has taken delivery of all the aircraft. In addition to the firm orders, Mesa has an option to acquire an additional 80 CRJ-700 and CRJ-900 regional jets. In January 2004, the Company exercised its option to convert options on

12

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) — (Continued)
20 CRJ-900 aircraft to firm orders (seven of which can be converted to CRJ-700s). We are currently in discussions with one of our code-share partners regarding the timing and delivery of the last three CRJ-900s on order. In addition to the firm orders, Mesa has an option to acquire an additional 60 CRJ-700 and CRJ-900 regional jets. In conjunction with this purchase agreement, Mesa had $15.0 million on deposit with BRAD that was included in lease and equipment deposits at March 31, 2005. The Company borrowed $13.2 million against these aircraft delivery deposits and placed these funds on deposit with the EDC. Amounts on deposit will be returned to BRAD upon the earlier of payment in full of the interim financing or completion of permanent financing. The remaining deposits are expected to be returned upon completion of permanent financing on each of the last five aircraft ($3.0 million per aircraft).
      The Company is also involved in various other legal proceedings and FAA civil action proceedings that the Company does not believe will have a material adverse effect upon the Company’s business, financial condition or results of operations, although no assurance can be given to the ultimate outcome of any such proceedings.
17. New Accounting Pronouncement
      On December 16, 2004, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 123R, “Share-Based Payment,” requiring all share-based payments to employees, including grants of employee stock options, to be recognized as compensation expense in the consolidated financial statements based on their fair values. This standard is effective for fiscal years beginning after June 15, 2005 and includes two transition methods. Upon adoption, we will be required to use either the modified prospective or the modified retrospective transition method. Under the modified prospective method, awards that are granted, modified, or settled after the date of adoption should be measured and accounted for in accordance with SFAS 123R. Unvested equity-classified awards that were granted prior to the effective date should continue to be accounted for in accordance with SFAS 123 except that amounts must be recognized in the income statement. Under the modified retrospective approach, the previously-reported amounts are restated (either to the beginning of the year of adoption or for all periods presented) to reflect the SFAS 123 amounts in the income statement. We are currently evaluating the impact of this standard and its transitional alternatives.
18. Subsequent Event
      On May 4, 2005, we announced a code-share arrangement between Mesa Air Group, one of our subsidiaries, Freedom Airlines, Inc., and Delta Air Lines, Inc. that provides for Freedom Airlines to become a Delta Connection partner.
      Under the terms of this arrangement, Freedom Airlines will operate up to 30 50-seat regional jet aircraft on routes throughout Delta’s network, with the first five aircraft planned to enter Delta Connection service as early as October 2005. The arrangement provides for certain reimbursement obligations between the parties and in exchange for performing the flight services under the agreement, Delta will pay the Company an amount, as defined in the agreement, which is based on an annual determination of the Company’s cost of operating those flights and other factors intended to approximate market rates for those services. The Company will be paid a base margin and be eligible for monthly and semi-annual incentive compensation based upon the Company’s achievement of certain operational objectives. The code-share agreement will terminate with respect to each aircraft, on an aircraft-by-aircraft basis, beginning in approximately twelve years.
19. Reclassifications
      Certain 2004 amounts previously reported have been reclassified to conform with the 2005 presentation.

      The following discussion and analysis provides information which management believes is relevant to an assessment and understanding of our results of operations and financial condition. The discussion should be read in conjunction with the Consolidated Financial Statements and the related notes thereto, and the Selected Financial Data and Operating Data contained elsewhere herein.
Forward-Looking Statements
      This Quarterly Report on Form 10-Q contains certain statements including, but not limited to, information regarding the replacement, deployment, and acquisition of certain numbers and types of aircraft, and projected expenses associated therewith; costs of compliance with Federal Aviation Administration regulations and other rules and acts of Congress; the passing of taxes, fuel costs, inflation, and various expenses to the consumer; the relocation of certain operations of Mesa; the resolution of litigation in a favorable manner and certain projected financial obligations. These statements, in addition to statements made in conjunction with the words “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “estimate,” and similar expressions, are forward-looking statements within the meaning of the Safe Harbor provision of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements relate to future events or the future financial performance of Mesa and only reflect management’s expectations and estimates. The following is a list of factors, among others, that could cause actual results to differ materially from the forward-looking statements: changing business conditions in certain market segments and industries; changes in Mesa’s code-sharing relationships; the inability of America West, US Airways, Delta Air Lines or United Airlines to pay their obligations under the code-share agreements; the inability of United Airlines and/or US Airways to successfully restructure and emerge from bankruptcy; the ability of US Airways to reject our code-share agreements in bankruptcy; an increase in competition along the routes Mesa operates or plans to operate; material delays in completion by the manufacturer of the ordered and yet-to-be delivered aircraft; availability and cost of funds for financing new aircraft; changes in general economic conditions; changes in fuel price; changes in regional economic conditions; Mesa’s relationship with employees and the terms of future collective bargaining agreements; the impact of current and future laws, additional terrorist attacks; Congressional investigations, and governmental regulations affecting the airline industry and Mesa’s operations; bureaucratic delays; amendments to existing legislation; consumers unwilling to incur greater costs for flights; unfavorable resolution of negotiations with municipalities for the leasing of facilities; and risks associated with litigation outcomes. One or more of these or other factors may cause Mesa’s actual results to differ materially from any forward-looking statement. Mesa is not undertaking any obligation to update any forward-looking statements contained in this Form 10-K.
      All references to “we,” “our,” “us,” or “Mesa” refer to Mesa Air Group, Inc. and its predecessors, direct and indirect subsidiaries and affiliates.
      Investors should read the risks identified under “Risk Factors” below for a more detailed discussion of these and other factors.
GENERAL
      Mesa Air Group, Inc. and its subsidiaries (collectively referred to herein as “Mesa” or the “Company”) is an independently owned regional airline serving 173 cities in 43 states, the District of Columbia, Canada, Mexico and the Bahamas. At March 31, 2005, Mesa operated a fleet of 178 aircraft with over 1,100 daily departures.
      As of March 31, 2005, Mesa’s airline operations are conducted by three regional airline subsidiaries primarily utilizing hub-and-spoke systems. Mesa Airlines, a wholly owned subsidiary of Mesa, operates as America West Express under a code-share and revenue guarantee agreement with America West Airlines, Inc. (“America West”), as United Express under a code-share and revenue guarantee agreement with United Airlines, Inc. (“United Airlines” or “United”) and as US Airways Express under a code-share and revenue guarantee agreement with US Airways, Inc. (“US Airways”). Air Midwest, Inc. (“Air Midwest”), a wholly

owned subsidiary of Mesa, operates as US Airways Express under a code-share agreement with US Airways, as America West Express under a code-share agreement with America West, and also operates an independent division, doing business as Mesa Airlines, from Albuquerque, New Mexico and Dallas, Texas. Air Midwest also has a code-share agreement with Midwest Airlines (“Midwest”) in Kansas City on flights operated as US Airways Express. In addition, Freedom Airlines, Inc., a wholly owned subsidiary of the Company, operates as America West express under a code-share agreement with America West.
      Approximately 99% of our consolidated passenger revenues for the six months ended March 31, 2005 were derived from operations associated with code-share agreements. Our subsidiaries have code-share agreements with America West, Midwest Airlines, United Airlines and US Airways. These code-share agreements allow use of the code-share partner’s reservation system and flight designator code to identify flights and fares in computer reservation systems, permit use of logos, service marks, and aircraft paint schemes and uniforms similar to the code-share partners and provide coordinated schedules and joint advertising.
      In addition to carrying passengers, we carry freight and express packages on our passenger flights and have interline small cargo freight agreements with many other carriers. We also have contracts with the U.S. Postal Service for carriage of mail to the cities we serve and occasionally operate charter flights when our aircraft are not otherwise used for scheduled service.

Recent Development
DELTA Code-Sharing Agreement
      On May 4, 2005, we announced a code-share arrangement between Mesa Air Group, one of our subsidiaries, Freedom Airlines, Inc., and Delta Air Lines, Inc. that provides for Freedom Airlines to become a Delta Connection partner.
      Under the terms of this arrangement, Freedom Airlines will operate up to 30 50-seat regional jet aircraft on routes throughout Delta’s network, with the first five aircraft planned to enter Delta Connection service as early as October 2005. The arrangement provides for certain reimbursement obligations between the parties and in exchange for performing the flight services under the agreement, Delta will pay the Company an amount, as defined in the agreement, which is based on an annual determination of the Company’s cost of operating those flights and other factors intended to approximate market rates for those services. The Company will be paid a base margin and be eligible for monthly and semi-annual incentive compensation based upon the Company’s achievement of certain operational objectives. The code-share agreement will terminate with respect to each aircraft, on an aircraft-by-aircraft basis, beginning in approximately twelve years.

RESULTS OF OPERATIONS
For the three months ended March 31, 2005 versus the three months ended March 31, 2004
Operating Revenues
      In the quarter ended March 31, 2005, operating revenue increased by $54.1 million, or 25.8%, from $209.7 million in the quarter ended March 31, 2004 to $263.8 million in the reporting period. The increase in revenue is primarily attributable to a $60.6 million increase in revenue associated with the operation of 20 additional regional jets and three Dash 8 aircraft flown by Mesa compared to the quarter ended March 31, 2004. Offsetting this increase was a net decrease in revenue of approximately $7.1 million at Air Midwest and Freedom. The decrease in revenue at Air Midwest and Freedom was primarily comprised of a $7.9 million decrease in passenger revenue, which was offset by a $1.0 million increase in Essential Air Program subsidies. The decrease in passenger revenue was due to a reduction of nine Beechcraft 1900D aircraft from 35 in March 2004 to 26 in March 2005.
Operating Expenses
Flight Operations
      In the quarter ended March 31, 2005, flight operations expense increased $5.2 million, or 7.1%, to $79.1 million from $73.9 million for the quarter ended March 31, 2004. On an ASM basis, flight operations expense decreased 17% to 3.9 cents per ASM in the quarter ended March 31, 2005 from 4.7 cents per ASM in the quarter ended March 31, 2004. The increase in expense is consistent with the increased capacity from the regional jets added to Mesa’s fleet since last year. The decrease on an ASM basis is due to the addition of larger regional jets at Mesa and the reduction in turboprop aircraft at Air Midwest and Freedom.
Fuel
      In the quarter ended March 31, 2005, fuel expense increased $22.4 million, or 52.4%, to $65.2 million from $42.8 million for the quarter ended March 31, 2004. On an ASM basis, fuel expense increased 18.5% to 3.2 cents per ASM in the quarter ended March 31, 2005 from 2.7 cents per ASM in the quarter ended March 31, 2004. Into-plane fuel cost increased 28.8% per gallon, resulting in a $12.2 million unfavorable price variance and consumption increased 19.0% resulting in a $10.4 million unfavorable volume variance (excluding fuel used in other operations). The increase in volume was due to the additional regional jets added to the fleet. In the quarter ended March 31, 2005, approximately 95% of our fuel costs were reimbursed by our code-share partners.
Maintenance Expense
      In the quarter ended March 31, 2005, maintenance expense increased $9.7 million, or 26.2%, to $46.9 million from $37.2 million for the quarter ended March 31, 2004. On an ASM basis, maintenance expense remained consistent at 2.3 cents per ASM in the quarter ended March 31, 2005 and the quarter ended March 31, 2004, respectively. Mesa’s maintenance expense increased $9.7 million primarily as a result of increases in the number of aircraft in its fleet, repair costs on certain rotable parts, headcount and engine overhaul expenses. This increase was offset by a $1.6 million decrease at Air Midwest and Freedom as a result of reductions in its fleet.
Aircraft and Traffic Servicing
      In the quarter ended March 31, 2005, aircraft and traffic servicing expense increased by $1.6 million, or 9.8%, to $17.6 million from $16.0 million for the quarter ended March 31, 2004. On an ASM basis, aircraft and traffic servicing expense decreased 10% to 0.9 cents per ASM in the quarter ended March 31, 2005 from 1.0 cents per ASM in the quarter ended March 31, 2004. The increase in expense is primarily related to a 33.5% increase in regional jet departures. The decrease on an ASM basis is due to the efficiencies attained by adding additional regional jets at Mesa and the reduction in turboprop aircraft at Air Midwest and Freedom.

Promotion and Sales
      In the quarter ended March 31, 2005, promotion and sales expense decreased $0.6 million, or 43.5%, to $0.8 million from $1.4 million for the quarter ended March 31, 2004. On an ASM basis, promotion and sales expense remained flat at 0.1 cents per ASM in the quarters ended March 31, 2005 and 2004. The decrease in expense is due to a decline in booking and franchise fees paid by Air Midwest and Freedom under the Company’s pro-rate agreements with its code-share partners, caused by a decline in passengers carried under these agreements. The Company does not pay these fees under its regional jet revenue-guarantee contracts.
General and Administrative
      In the quarter ended March 31, 2005, general and administrative expense increased $0.8 million, or 4.9%, to $15.7 million from $14.9 million for the quarter ended March 31, 2004. On an ASM basis, general and administrative expense decreased 11.1% to 0.8 cents per ASM in quarter ended March 31, 2005 from 0.9 cents per ASM in the quarter ended March 31, 2004. The increase in expense includes $1.1 million in consulting costs related to Sarbanes Oxley compliance, a $0.8 million increase in property taxes and a $0.3 million increase in passenger liability insurance, both due to increases in headcount. The increase in expense is also due to the reversal of $0.9 million in merger related costs in the second quarter of fiscal 2004. Offsetting these increases was a $3.1 million decrease in executive compensation costs as a result of the restructuring of employment contracts of top executives in the second quarter of fiscal 2004.
Depreciation and Amortization
      In the quarter ended March 31, 2005, depreciation and amortization expense increased $4.7 million, or 86.7%, to $10.1 million from $5.4 million for the quarter ended March 31, 2004. On an ASM basis, depreciation expense increased 66.7% to 0.5 cents per ASM in the quarter ended March 31, 2005 from 0.3 cents per ASM in the quarter ended March 31, 2004. The increase in depreciation expense is primarily due to depreciation on 13 additional CRJ-900 aircraft acquired and operating since March 31, 2004.
Interest Expense
      In the quarter ended March 31, 2005, interest expense increased $5.0 million, or 95.2%, to $10.2 million from $5.2 million for the quarter ended March 31, 2004. On an ASM basis, interest expense increased to 0.5 cents per ASM in the quarter ended March 31, 2005 from 0.3 cents per ASM in the quarter ended March, 31 2004. The increase in interest expense is primarily comprised of an increase of $4.2 million in interest on interim and permanently financed aircraft debt and a $0.4 million increase in interest on the senior convertible notes that were issued in February 2004.
Other Income (Expense)
      In the quarter ended March 31, 2005, other income (expense) increased $2.2 million, or 197.2%, to $1.1 million in expense from $1.1 million in income for the quarter ended March 31, 2004. In the quarter ended March 31, 2005, other income (expense) is primarily comprised of an investment loss of $2.7 million related to the Company’s portfolio of aviation related securities and $1.0 million income from a settlement of a dispute with a vendor.
      In the quarter ended March 31, 2004, other income was primarily comprised of investment income of $1.0 million related to the Company’s portfolio of aviation related securities.
For the six months ended March 31, 2005 versus the six months ended March 31, 2004
Operating Revenues
      In the six months ended March 31, 2005, operating revenue increased by $131.4 million, or 33.1%, from $397.2 million in the six month period ended March 31, 2004 to $528.6 million in the reporting period. The increase in revenue is primarily attributable to a $136.4 million increase in revenue associated with the operation of the additional regional jets flown by Mesa compared to the quarter ended March 31, 2004.

Offsetting this increase was a net decrease in revenue of approximately $6.4 million at Air Midwest and Freedom. The decrease in revenue at Air Midwest and Freedom was primarily comprised of a $8.5 million decrease in passenger revenue, which was offset by a $2.3 million increase in Essential Air Program subsidies. The decrease in passenger revenue was due to a reduction of 9 Beechcraft 1900D aircraft from 35 in March 2004 to 26 in March 2005.
Operating Expenses
Flight Operations
      In the six months ended March, 31, 2005, flight operations expense increased $19.6 million, or 14.1%, to $158.3 million from $138.7 million for the six months ended March 31, 2004. On an ASM basis, flight operations expense decreased 15.2% to 3.9 cents per ASM in the six months ended March 31, 2005 from 4.6 cents per ASM in the six months ended March 31, 2004. The increase in expense is consistent with the increased capacity from the regional jets added to Mesa’s fleet since last year. The decrease on an ASM basis is due to the addition of larger regional jets at Mesa and the reduction in turboprop aircraft at Air Midwest and Freedom.
Fuel
      In the six months ended March 31, 2005, fuel expense increased $53.6 million, or 68.1%, to $132.3 million from $78.7 million for the six months ended March 31, 2004. On an ASM basis, fuel expense increased 26.9% to 3.3 cents per ASM in the six months ended March 31, 2005 from 2.6 cents per ASM in the six months ended March 31, 2004. Into-plane fuel cost increased 34% per gallon, resulting in a $26.6 million unfavorable price variance and consumption increased 26% resulting in a $26.9 million unfavorable volume variance (excluding fuel used in other operations). The increase in volume was due to the additional regional jets added to the fleet.
Maintenance Expense
      In the six months ended March 31, 2005, maintenance expense increased $21.6 million, or 29.3%, to $95.5 million from $73.9 million for the six months ended March 31, 2004. On an ASM basis, maintenance expense remained flat at 2.4 cents per ASM in the six months ended March 31, 2005 and the six months ended March 31, 2004 respectively. Mesa’s maintenance expense increased $21.4 million primarily as a result of increases in the number of aircraft in their fleet, repair costs on certain rotable parts, headcount and engine overhaul expenses. This increase was offset by a $1.7 million decrease at Air Midwest and Freedom as a result of reductions in its fleet.
Aircraft and Traffic Servicing
      In the six months ended March 31, 2005, aircraft and traffic servicing expense increased by $4.5 million, or 15.1%, to $34.4 million from $29.9 million for the six months ended March 31, 2004. On an ASM basis, aircraft and traffic servicing expense decreased 10% to 0.9 cents per ASM in the six months ended March 31, 2005 from 1.0 cents per ASM in the six months ended March 31, 2004. The increase in expense is primarily related to a 35.3% increase in regional jet departures. The decrease on an ASM basis is due to the efficiencies attained by adding additional regional jets at Mesa and the reduction in turboprop aircraft at Air Midwest and Freedom.
Promotion and Sales
      In the six months ended March 31, 2005, promotion and sales expense decreased $0.9 million, or 30.1%, to $2.2 million from $3.1 million for the six months ended March 31, 2004. On an ASM basis, promotion and sales expense remained flat at 0.1 cents per ASM in the quarters ended March 31, 2005 and 2004. The decrease in expense is due to a decline in booking and franchise fees paid by Air Midwest and Freedom under the Company’s pro-rate agreements with its code-share partners, caused by a decline in passengers carried

under these agreements. The Company does not pay these fees under its regional jet revenue-guarantee contracts.
General and Administrative
      In the six months ended March 31, 2005, general and administrative expense decreased $0.8 million, or 2.6%, to $31.2 million from $32.0 million for the six months ended March 31, 2004. On an ASM basis, general and administrative expense decreased 27.3% to 0.8 cents per ASM in the six months ended March 31, 2005 from 1.1 cents per ASM in the six months ended March 31, 2004. The decrease in general and administrative expenses from last year is due 2004 including $3.8 million in merger related costs and $2.8 million in executive compensation costs as a result of the restructuring of employment contracts of top executives. These reductions were offset by a $1.4 million increase in property taxes and a $1.0 million increase in passenger liability insurance, both due to increases in the Company’s fleet, $1.2 million in consulting costs related to Sarbanes Oxley compliance, a $0.8 million increase in bad debt expense, a $0.6 million increase in health insurance costs as a result of increased headcount and $0.8 million in other miscellaneous general administrative expense increases.
Depreciation and Amortization
      In the six months ended March 31, 2005, depreciation and amortization expense increased $7.9 million, or 69.6%, to $19.3 million from $11.4 million for the six months ended March 31, 2004. On an ASM basis, depreciation expense increased 69.6% to 0.5 cents per ASM in the six months ended March 31, 2005 from 0.4 cents per ASM in the six months ended March 31, 2004. The increase in depreciation expense is primarily due to depreciation on 13 additional CRJ-900 aircraft acquired since March 31, 2004.
Impairment and Restructuring Charges (Credits)
      In the six months ended March 31, 2005, the Company reversed $1.3 million in reserves for lease and lease return costs related to two Shorts 360 aircraft the Company returned to the lessor in January 2005.
      In the six months ended March 31, 2004, the Company recognized an impairment charge of $11.3 million related to the planned early return of seven leased B1900D aircraft with lease expirations between December 2004 and September 2005. The charge included $2.4 million for the present value of future lease payments, $2.4 million for the negotiated settlement of return conditions, $1.2 million for the cancellation of maintenance agreements, $0.8 million to reduce maintenance deposits to net realizable value and $4.5 million to reduce the value of rotable and expendable inventory to fair value less costs to sell.
Interest Expense
      In the six months ended March 31, 2005, interest expense increased $8.2 million, or 76.8%, to $18.9 million from $10.7 million for the six months ended March 31, 2004. On an ASM basis, interest expense increased to 0.5 cents per ASM in the six months ended March 31, 2005 from 0.4 cents per ASM in the six months ended March, 31 2004. The increase in interest expense is primarily comprised of an increase of $6.2 million in interest on interim and permanently financed aircraft debt and a $1.3 million increase in interest on the senior convertible notes that were issued in February 2004.
Other Income (Expense)
      In the six months ended March 31, 2005, other income (expense) decreased $0.5 million, or 31.6%, to $1.3 million in income from $1.8 million in income for the six months ended March 31, 2004. In the six months ended March 31, 2005, other income (expense) is primarily comprised of investment income of $2.1 million, $2.4 million in insurance proceeds on the Company’s EMB120 aircraft and $1.0 million income from a settlement of a dispute with a vendor, offset by $4.1 million in lease return costs on the EMB120s.
      Other income (expense) for the six months ended March 31, 2004 is primarily attributable to investment income of $1.7 million related to the Company’s portfolio of aviation related securities.

LIQUIDITY AND CAPITAL RESOURCES
Sources and Uses of Cash
      At March 31, 2005, we had cash, cash equivalents, and marketable securities (including restricted cash) of $255.9 million, compared to $241.1 million at September 30, 2004. Our cash and cash equivalents and marketable securities are intended to be used for working capital, capital expenditures, acquisitions, and to fund our obligations with respect to regional jet deliveries.
      Sources of cash included $56.1 million provided from operations and $3.0 million in returned security deposits.
      Uses of cash included capital expenditures of $28.2 million attributable to the expansion of our regional jet fleet and related provisioning of rotable inventory to support the additional jets, $12.9 million in principal payments on long-term debt and $3.7 million in purchases of the Company’s outstanding common stock.
      As of March 31, 2005, we had receivables of approximately $21.4 million (net of an allowance for doubtful accounts of $8.2 million), compared to receivables of approximately $30.7 million (net of an allowance for doubtful accounts of $7.1 million) as of September 30, 2004. The amounts due consist primarily of receivables due from our code-share partners and passenger ticket receivables due through the Airline Clearing House. The decrease is primarily a result of collection of amounts due from Raytheon and collections from our code-share partners. Accounts receivable from our code-share partners was 47% of total gross accounts receivable at March 31, 2005.
Operating Leases
      We have significant long-term lease obligations primarily relating to our aircraft fleet. These leases are classified as operating leases and are therefore excluded from our consolidated balance sheets. At March 31, 2005, we leased 136 aircraft with remaining lease terms ranging from one to 17 years. Future minimum lease payments due under all long-term operating leases were approximately $1.9 billion at March 31, 2005.
Interim and Permanent Aircraft Financing Arrangements
      At March 31, 2005, we had $277.5 million in notes payable for aircraft on interim financing. Under interim financing arrangements, we take delivery and title to the aircraft prior to securing permanent financing and the acquisition of the aircraft is accounted for as a purchase with debt financing. Accordingly, we reflect the aircraft and debt under interim financing on our balance sheet during the interim financing period. These interim financings agreements are through November 30, 2005 and provide for monthly interest only payments at LIBOR plus three percent. Under the interim financing arrangements, the manufacturer has provided a portion of the financing with the remainder being provided by Export Development Canada (“EDC”). As part of the financing with the EDC, the Company is required to maintain a deposit of five percent of the aircraft value with EDC. Pursuant to this requirement, the Company borrowed $13.2 million against its aircraft delivery deposits with the manufacturer and placed these funds on deposit with the EDC. Amounts on deposit will be returned to the manufacturer upon the earlier of payment in full of the interim financing or completion of permanent financing.
      The Company’s interim financing agreement with the manufacturer provides for the Company to have a maximum of 15 aircraft on interim financing at a given time. After taking delivery of the aircraft, it is our intention to subsequently enter into a sale-leaseback transaction with an independent third-party lessor when market lease rates permit. Our ability to obtain additional interim financing is contingent upon obtaining permanent financing for the aircraft already delivered. There are no assurances that we will be able to obtain permanent financing for future aircraft deliveries.
Other Indebtedness and Obligations
      At March 31, 2005, the Company had $10.3 million in restricted cash on deposit with two financial institutions. In September 2004, the Company entered into an agreement with a financial institution for a

21


Table of Contents

$9.0 million letter of credit facility and to issue letters of credit for landing fees, workers compensation insurance and other business needs. Pursuant to the agreement, $5.0 million of outstanding letters of credit were collateralized by amounts on deposit at March 31, 2005. The Company also maintained $5.3 million on deposit with another financial institution to collateralize its direct deposit payroll.
      Our Board of Directors has authorized us to repurchase up to 9.4 million shares of our outstanding common stock (including 1.0 million shares authorized on April 22, 2005). As of March 31, 2005, we acquired and retired approximately 6.8 million shares of our outstanding common stock at an aggregate cost of approximately $40.0 million, leaving approximately 2.6 million shares available for repurchase under the existing Board authorizations. The timing of repurchases and the actual number of shares repurchased will depend on market conditions, alternative uses of capital and other considerations.
Contractual Obligations
      As of March 31, 2005, we had $677.8 million of long-term debt (including current maturities). This amount consisted of $473.5 million in notes payable related to owned aircraft, $200.1 in aggregate principal amount of our senior convertible notes due 2023 and 2024 and $4.2 million in other miscellaneous debt.
      The following table sets forth our cash obligations as of March 31, 2005.

Critical Accounting Estimates and Judgments
      The discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. In connection with the preparation of these financial statements, we are required to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, and expenses, and related disclosure of contingent liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, the allowance for doubtful accounts, medical claims reserve, valuation of assets held for sale and costs to return aircraft and a valuation allowance for certain deferred tax assets. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Such historical experience and assumptions form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
      We have identified the accounting policies below as critical to our business operations and the understanding of our results of operations. The impact of these policies on our business operations is discussed throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations where such policies affect our reported and expected financial results. The discussion below is not intended to be a comprehensive list of our accounting policies. For further discussion on the application of these and other accounting policies, see Note 1 in the Notes to the Consolidated Financial Statements in Form 10-K, which contains accounting policies and other disclosures required by accounting principles generally accepted in the United States of America.
Revenue Recognition
      The America West, United and the US Airways regional jet code-share agreements are revenue-guarantee flying agreements. Under a revenue-guarantee arrangement, the major airline generally pays a fixed monthly minimum amount, plus certain additional amounts based upon the number of flights flown and block hours performed. The contracts also include reimbursement of certain costs incurred by Mesa in performing flight services. These costs, known as “pass-through costs,” may include aircraft ownership cost, passenger and hull insurance, aircraft property taxes as well as, fuel, landing fees and catering. In addition, the Company’s code-share partners also provide, at no cost to Mesa, certain ground handling and customer service functions, as well as airport-related facilities and gates at their hubs and other cities. The contracts also include a profit component that may be determined based on a percentage of profits on the Mesa flown flights, a profit margin on certain reimbursable costs as well as a profit margin based on certain operational benchmarks. The Company primarily recognizes revenue under its revenue-guarantee agreements when the transportation is provided. The majority of the revenue under these contracts is known at the end of the accounting period and is booked as actual. The Company performs an estimate of the profit component based upon the information available at the end of the accounting period. All revenue recognized under these contracts is presented at the gross amount billed.
      Under the Company’s revenue-guarantee agreements with America West, US Airway and United, the Company is reimbursed under a fixed rate per block-hour plus an amount per aircraft designed to reimburse the Company for certain aircraft ownership costs. In accordance with Emerging Issues Task Force Issue No. 01-08, “Determining Whether an Arrangement Contains a Lease,” the Company has concluded that a component of its revenue under the agreement discussed above is rental income, inasmuch as the agreement identifies the “right of use” of a specific type and number of aircraft over a stated period of time. The amounts

23


Table of Contents

deemed to be rental income during the quarters ended March 31, 2005 and 2004 were $57.8 million and $40.9 million, respectively. The amounts deemed to be rental income during the six months ended March 31, 2005 and 2004 were $114.1 million and $73.7 million, respectively. These amounts are included in passenger revenue on the Company’s statements of income.
      The America West, US Airways, and Midwest Airlines turboprop code-share agreements are pro-rate agreements. Under a pro-rate agreement, the Company receives a percentage of the passenger’s fare based on a standard industry formula that allocates revenue based on the percentage of transportation provided. Revenue from the Company’s pro-rate agreements and the Company’s independent operation is recognized when transportation is provided. Tickets sold but not yet used are included in air traffic liability on the consolidated balance sheets.
      The Company also receives subsidies for providing scheduled air service to certain small or rural communities. Such revenue is recognized in the period in which the air service is provided. The amount of the subsidy payments is determined by the United States Department of Transportation on the basis of its evaluation of the amount of revenue needed to meet operating expenses and to provide a reasonable return on investment with respect to eligible routes. Essential Air Service (“EAS”) rates are normally set for two-year contract periods for each city.
Allowance for Doubtful Accounts
      Amounts billed by the Company under revenue guarantee arrangements are subject to our interpretation of the applicable code-share agreement and are subject to audit by our code-share partners. Periodically our code-share partners dispute amounts billed and pay amounts less than the amount billed. Ultimate collection of the remaining amounts not only depends upon Mesa prevailing under audit, but also upon the financial well-being of the code-share partner. As such, the Company periodically reviews amounts past due and records a reserve for amounts estimated to be uncollectible. The allowance for doubtful accounts was $8.2 million and $7.1 million at March 31, 2005 and September 30, 2004, respectively. If the Company’s actual ability to collect these receivables and the actual financial viability of its partners is materially different than estimated, the Company’s estimate of the allowance could be materially understated or overstated.
Accrued Health Care Costs
      The Company is currently self-insured for health care costs and as such, a reserve for the cost of claims that have not been paid as of the balance sheet date is estimated. The Company’s estimate of this reserve is based upon historical claim experience and upon the recommendations of its health care provider. At March 31, 2005 and September 2004, the Company accrued $2.7 million and $2.2 million, respectively, for the cost of future health care claims. If the ultimate development of these claims is significantly different than those that have been estimated, the reserves for future health care claims could be materially overstated or understated.
Long-lived Assets, Aircraft and Parts Held for Sale
      Property and equipment are stated at cost and depreciated over their estimated useful lives to their estimated salvage values using the straight-line method. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may be impaired. Under the provisions of Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” the Company records an impairment loss if the undiscounted future cash flows are found to be less than the carrying amount of the asset. If an impairment loss has occurred, a charge is recorded to reduce the carrying amount of the asset to fair value. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.
Valuation Allowance for Deferred Tax Assets
      The Company records deferred tax assets for the value of benefits expected to be realized from the utilization of alternative minimum tax credit carryforwards and state and federal net operating loss

24


Table of Contents

carryforwards. The Company periodically reviews these assets for realizability based upon expected taxable income in the applicable taxing jurisdictions. To the extent the Company believes some portion of the benefit may not be realizable, an estimate of the unrealized portion is made and an allowance is recorded. At March 31, 2005, the Company had no valuation allowance for deferred tax assets as it believes it will generate sufficient taxable income in the future to realize its recorded deferred tax assets. This belief is based upon the Company having had pretax income in fiscal 2004, 2003 and 2002 (excluding impairment charges) and as the Company has taken steps to minimize the financial impact of its unprofitable subsidiaries. Realization of these deferred tax assets is dependent upon generating sufficient taxable income prior to expiration of any net operating loss carryforwards. Although realization is not assured, management believes it is more likely than not that the recorded deferred tax assets will be realized. If the ultimate realization of these deferred tax assets is significantly different from the Company’s expectations, the value of its deferred tax assets could be materially overstated.

CRJ Program
      In August 1996, we entered into an agreement (the “1996 BRAD Agreement”) with Bombardier Regional Aircraft Division (“BRAD”) to acquire 32 CRJ-200 50-passenger regional jet aircraft. The 32 aircraft have been delivered and are currently under permanent financing as operating leases with initial terms of 16.5 to 18.5 years.
      In May 2001, we entered into a second agreement with BRAD (the “2001 BRAD Agreement”) under which we committed to purchase a total of 15 CRJ-700s and 25 CRJ-900s. In January 2004, the Company exercised options to purchase 20 CRJ-900 aircraft (seven of which can be converted to CRJ-700 aircraft) reserved under the option provision of the 2001 BRAD Agreement. The transaction includes standard product support provisions, including training, preferred pricing on initial inventory provisioning, maintenance and technical publications. We have accepted delivery of 15 CRJ-700s under the 2001 BRAD Agreement. We are the launch customer of the CRJ-900 and as of March 31, 2005, have taken delivery of 30 CRJ-900 aircraft. We are currently in discussions with one of our code-share partners regarding the timing and delivery of the last three CRJ-900s on order. In addition to the firm orders, we have an option to acquire an additional 60 CRJ-700 or CRJ-900 regional jets. In conjunction with the 2001 BRAD Agreement, we had $15.0 million on deposit with BRAD, which was included with lease and equipment deposits at March 31, 2005.
      In 2004, we leased nine used CRJ-200 and CRJ-100 aircraft in order to meet required deliveries under our code-share agreements. The aircraft are financed as operating leases.
      Also in 2004, the Company acquired eight CRJ 200 aircraft through the purchase of the assets of Midway. Of the eight aircraft acquired, two are owned and six are leased.
ERJ Program
      As of March 31, 2005, we operated 36 Embraer 145 aircraft.
Beechcraft 1900D
      As of March 31, 2005, we owned 35 Beechcraft 1900D aircraft and were operating 26 of these aircraft. In October 2004 the Company entered into an agreement to lease four of its Beechcraft 1900D aircraft operated by Air Midwest to Gulfstream International Airlines, a regional turboprop air carrier based in Ft. Lauderdale, Florida. These aircraft and three other Beech 1900s were taken out of the Company’s Florida operations in the first quarter. The Company also signed an agreement to lease an additional ten Beechcraft 1900D aircraft to Big Sky Transportation Co. (“Big Sky”). Pursuant to the agreement with Big Sky, five additional aircraft were taken out of service in the second quarter of fiscal 2005.
Dash-8
      As of March 31, 2005, we operated 16 leased Dash-8 aircraft.
Aircraft Financing Relationships with the Manufacturer
      It is customary business practice to enter into interim financing with the manufacturer. Under interim financing arrangements, the Company takes delivery and title of the aircraft prior to securing permanent financing. After taking delivery of the aircraft, it is the Company’s intention to subsequently enter into a sale-leaseback transaction with an independent third-party lessor. Occasionally the Company will permanently finance aircraft with long-term debt, but it is our current intention to permanently finance aircraft as operating leases rather than debt. The Company currently has five aircraft on interim financing. These interim financings agreements are through November 30, 2005 and provide for monthly interest only payments at LIBOR plus three percent. The current interim financing agreement with the manufacturer provides for the Company to have a maximum of 15 aircraft on interim financing at a given time.

Risk Factors
      The following risk factors, in addition to the information discussed elsewhere herein, should be carefully considered in evaluating us and our business:
Risks Related to Our Business
The negative impact of the September 11, 2001 terrorist attacks and the resulting government responses could be material to our financial condition, results of operations and prospects.
      The terrorist attacks of September 11, 2001 were highly publicized. The impacts that these events will continue to have on the airline industry in general, and on us in particular, is not known at this time, but is expected to include a substantial impact on our operations due to:
  •  a reduction in the demand for travel in the near and mid-term until public confidence in the air transportation system is restored;
 
  •  an increase in costs due to enhanced security measures and government directives in response to the terrorist attacks;
 
  •  an increase in the cost of aviation insurance in general, and the cost and availability of coverage for acts of war, terrorism, hijacking, sabotage and similar acts of peril in particular; and
 
  •  an increase in airport rents and landing fees.
      In addition, we expect that the general increase in hostilities relating to reprisals against terrorist organizations and the continued threat of further terrorist attacks will continue to negatively impact our revenues and costs in the near and mid-term. The extent of the impact that the terrorist attacks and their aftermath will have on our operations, and the sufficiency of our financial resources to absorb this impact, will depend on a number of factors, including:
  •  the adverse impact that terrorist attacks, and the resulting government responses, will have on the travel industry and the economy in general;
 
  •  the potential increase in fuel costs and decrease in availability of fuel if oil-producing countries are affected by the aftermath of the terrorist attacks, including the government’s responses, and our ability to manage this risk in connection with that part of our operations where our fuel costs are not reimbursed by our code-share partners under the terms of our code-share agreements;
 
  •  our ability to reduce our operating costs and conserve financial resources, taking into account the cost increases (including significant increases in the cost of aviation insurance) expected to result from the aftermath of the terrorist attacks and the government’s responses;
 
  •  any resulting decline in the value of the aircraft in our fleet;
 
  •  our ability to raise additional financing, if necessary, taking into account our current leverage and the limitations imposed by the terms of our existing indebtedness;
 
  •  the number of crew members who may be called for duty in the reserve forces of the armed services and the resulting impact on our ability to operate as planned; and
 
  •  the scope and nature of any future terrorist attacks.
We are dependent on our agreements with our code-share partners.
      We depend on relationships created by our code-share agreements. We derive a significant portion of our consolidated passenger revenues from our revenue guarantee code-share agreements with America West, United Airlines, and US Airways. Our code-share partners have certain rights to cancel the applicable code-share agreement upon the occurrence of certain events or the giving of appropriate notice, subject to certain conditions. Although no notice has been given to date that any party intends to cancel these contracts, there can be no assurance that they will not serve notice at a later date of their intention to cancel, forcing us to stop

selling those routes with the applicable partner’s code and potentially reducing our traffic and revenue. In addition, our code-share agreement with America West allows America West, subject to certain restrictions, to reduce the combined CRJ fleets utilized under the code-share agreement by one aircraft in any six-month period commencing in January 2007. In addition, beginning in February 2007, America West may eliminate the Dash-8 aircraft upon 180 days prior written notice. America West has used this provision to reduce the number of aircraft covered by the code-share agreement and there can be no assurance that, commencing in January 2007, they will not continue to further reduce the number of covered aircraft.
      In addition, because a majority of our operating revenues are currently generated under revenue-guarantee code-share agreements, if any one of them is terminated, our operating revenues and net income could be materially adversely affected unless we are able to enter into satisfactory substitute arrangements or, alternatively, fly under our own flight designator code, including obtaining the airport facilities and gates necessary to do so. For the quarter ended March 31, 2005, our America West code-share agreement accounted for 41% of our consolidated passenger revenues, our US Airways code-share agreement accounted for 34% of our consolidated passenger revenues and our United code-share agreement accounted for 24% of our consolidated passenger revenues. Any material modification to, or termination of, our code-share agreements with any of these partners could have a material adverse effect on our financial condition, the results of our operations and the price of our common stock. Should any of our revenue-guarantee code-share agreements be terminated, we cannot assure you that we would be able to enter into substitute code-share arrangements, that any such arrangements would be as favorable to us as the current code-share agreements or that we could successfully fly under our own flight designator code.
If our code-share partners or other regional carriers experience events that negatively impact their financial strength or operations, our operations also may be negatively impacted.
      We are directly affected by the financial and operating strength of our code-share partners. Any events that negatively impact the financial strength of our code-share partners or have a long-term effect on the use of our code-share partners by airline travelers would likely have a material adverse effect on our business, financial condition and results of operations. In the event of a decrease in the financial or operational strength of any of our code-share partners, such partner may seek to reduce, or be unable to make, the payments due to us under their code-share agreement. In addition, they may reduce utilization of our aircraft. Although there are certain monthly guaranteed payment amounts, there are no minimum levels of utilization specified in the code-share agreements. UAL Corp., the parent of our code-share partner United Airlines, has not emerged from reorganization under Chapter 11 of the U.S. Bankruptcy Code. Additionally, US Airways, which accounted for 34% of our consolidated passenger revenue for the quarter ended March 31, 2005, has filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. The financial performance of US Airways and United could directly affect their ability to perform under our code-share agreements with them. Additionally, US Airways has not yet assumed our code-share agreement in its bankruptcy proceedings and could choose to terminate this agreement. If any of our other current or future code-share partners become bankrupt, our code-share agreement with such partner may not be assumed in bankruptcy and would be terminated. This and other such events could have an adverse effect on our business, financial condition and results of operations. In addition, any negative events that occur to other regional carriers and that affect public perception of such carriers generally could also have a material adverse effect on our business, financial condition and results of operations.
Our code-share partners may expand their direct operation of regional jets thus limiting the expansion of our relationships with them.
      We depend on major airlines like America West, United Airlines and US Airways electing to contract with us instead of purchasing and operating their own regional jets. However, these major airlines possess the resources to acquire and operate their own regional jets instead of entering into contracts with us or other regional carriers. We have no guarantee that in the future our code-share partners will choose to enter into contracts with us instead of purchasing their own regional jets or entering into relationships with competing regional airlines. A decision by America West, United Airlines, or US Airways to phase out our contract-

28


Table of Contents

based code-share relationships or to enter into similar agreements with competitors could have a material adverse effect on our business, financial condition or results of operations. In addition to Mesa Airlines, US Airways and United Airlines have similar code-share agreements with other competing regional airlines. Mesa Airlines is currently America West’s only code-share partner.
If we experience a lack of labor availability or strikes, it could result in a decrease of revenues due to the cancellation of flights.
      The operation of our business is significantly dependent on the availability of qualified employees, including, specifically, flight crews, mechanics and avionics specialists. Historically, regional airlines have experienced high pilot turnover from time to time as a result of air carriers operating larger aircraft hiring their commercial pilots. Further, the addition of aircraft, especially new aircraft types, can result in pilots upgrading between aircraft types and becoming unavailable for duty during the required extensive training periods. There can be no assurance that we will be able to maintain an adequate supply of qualified personnel or that labor expenses will not increase.
      At March 31, 2005, we had approximately 4,600 employees, a significant number of whom are members of labor unions, including ALPA and the AFA. Our collective bargaining agreement with ALPA becomes amendable in September 2007 and our collective bargaining agreement with the AFA becomes amendable in June 2006. The inability to negotiate acceptable contracts with existing unions as agreements expire or with new unions could result in work stoppages by the affected workers, lost revenues resulting from the cancellation of flights and increased operating costs as a result of higher wages or benefits paid to union members. We cannot predict which, if any, other employee groups may seek union representation or the outcome or the terms of any future collective bargaining agreement and therefore the effect, if any, on our financial condition and results of operations. If negotiations with unions over collective bargaining agreements prove to be unsuccessful, following specified “cooling off” periods, the unions may initiate a work action, including a strike, which could have a material adverse effect on our business, financial condition and results of operations.
Increases in our labor costs, which constitute a substantial portion of our total operating costs, will cause our earnings to decrease.
      Labor costs constitute a significant percentage of our total operating costs, and we have experienced pressure to increase wages and benefits for our employees. Under our code-share agreements, our reimbursement rates contemplate labor costs that increase on a set schedule generally tied to an increase in the consumer price index or the actual increase in the contract. We are responsible for our labor costs, and we may not be entitled to receive increased payments under our code-share agreements if our labor costs increase above the assumed costs included in the reimbursement rates. As a result, a significant increase in our labor costs above the levels assumed in our reimbursement rates could result in a material reduction in our earnings.
If new airline regulations are passed or are imposed upon our operations, we may incur increased operating costs and experience a decrease in earnings.
      Laws and regulations, such as those described below, have been proposed from time to time that could significantly increase the cost of our operations by imposing additional requirements or restrictions on our operations. We cannot predict what laws and regulations will be adopted or what changes to air transportation agreements will be effected, if any, or how they will affect us, and there can be no assurance that laws or regulations currently proposed or enacted in the future will not increase our operating expenses and therefore adversely affect our financial condition and results of operations.
      As an interstate air carrier, we are subject to the economic jurisdiction, regulation and continuing air carrier fitness requirements of the Department of Transportation (“DOT”), which include required levels of financial, managerial and regulatory fitness. The DOT is authorized to establish consumer protection regulations to prevent unfair methods of competition and deceptive practices, to prohibit certain pricing practices, to inspect a carrier’s books, properties and records, to mandate conditions of carriage and to suspend

29


Table of Contents

an air carrier’s fitness to operate. The DOT also has the power to bring proceedings for the enforcement of air carrier economic regulations, including the assessment of civil penalties, and to seek criminal sanctions.
      We are also subject to the jurisdiction of the FAA with respect to our aircraft maintenance and operations, including equipment, ground facilities, dispatch, communication, training, weather observation, flight personnel and other matters affecting air safety. To ensure compliance with its regulations, the FAA requires airlines to obtain an operating certificate, which is subject to suspension or revocation for cause, and provides for regular inspections.
      We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not significantly increase our costs of doing business.
      The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fail in the future. A decision by the FAA to ground, or require time-consuming inspections of, or maintenance on, all or any of our turboprops or regional jets, for any reason, could negatively impact our results of operations.
      In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the use of smaller aircraft, such as Embraer or Canadair regional jets, at such airports. The imposition of any limits on the use of our regional jets at any airport at which we operate could interfere with our obligations under our code-share agreements and severely interrupt our business operations.
Fluctuations in fuel costs could adversely affect our operating expenses and results.
      The price and supply of jet fuel is unpredictable and fluctuates based on events outside our control, including geopolitical developments, regional production patterns and environmental concerns. Although approximately 95% of our fuel costs for the quarter ended March 31, 2005 was reimbursed by our code-share partners, price escalations or reductions in the supply of jet fuel will increase our operating expenses and, to the extent such fuel costs are not reimbursed by our code-share partners, could cause our operating results and net income to decline.
lf additional security and safety measures regulations are adopted, we may incur increased operating costs and experience a decrease in earnings.
      Congress recently adopted increased safety and security measures designed to increase airline passenger security and protect against terrorist acts. Such measures have resulted in additional operating costs to the airline industry. The Aviation Safety Commission’s report recommends the adoption of further measures aimed at improving the safety and security of air travel. We cannot forecast what additional security and safety requirements may be imposed on our operations in the future or the costs or revenue impact that would be associated with complying with such requirements, although such costs and revenue impact could be significant. To the extent that the costs of complying with any additional safety and security measures are not reimbursed by our code-share partners, our operating results and net income could be adversely affected.
If our operating costs increase as our aircraft fleet ages and we are unable to pass along such costs, our earnings will decrease.
      As our fleet of aircraft age, the cost of maintaining such aircraft, if not replaced, will likely increase. There can be no assurance that costs of maintenance, including costs to comply with aging aircraft requirements, will not materially increase in the future. Any material increase in such costs could have a material adverse effect on our business, financial condition and results of operations. Because many aircraft components are required to be replaced after specified numbers of flight hours or take-off and landing cycles, and because new aviation technology may be required to be retrofitted, the cost to maintain aging aircraft will

30


Table of Contents

generally exceed the cost to maintain newer aircraft. We believe that the cost to maintain our aircraft in the long-term will be consistent with industry experience for these aircraft types and ages used by comparable airlines.
      We believe that our aircraft are mechanically reliable based on the percentage of scheduled flights completed and as of March 31, 2005 the average age of our regional jet fleet is 2.8 years. However, there can be no assurance that such aircraft will continue to be sufficiently reliable over longer periods of time. Furthermore, any public perception that our aircraft are less than completely reliable could have a material adverse effect on our business, financial condition and results of operations.
Our fleet expansion program will require a significant increase in our leverage and the financing we require may not be available on favorable terms or at all.
      The airline business is very capital intensive and, as a result, many airline companies are highly leveraged. For the quarter ended March 31, 2005, our debt service payments totaled $22.8 million and our lease payments totaled $75.8 million. We have significant lease obligations with respect to our aircraft and ground facilities, which aggregated approximately $1.9 billion at March 31, 2005. As of March 31, 2005, our growth strategy involves the acquisition of 15 more Bombardier regional jets during the remainder of fiscal 2005 and 2006. As of March 31, 2005, we had permanently financed 35 of the 45 CRJ-700 and CRJ-900 aircraft delivered under the 2001 BRAD agreement; the remaining aircraft are subject to interim financing. We may utilize interim financing provided by the manufacturer and have the ability to fund up to 15 aircraft at any one time under this facility. Our ability to obtain additional interim financing is contingent upon obtaining permanent financing for the aircraft already delivered. There are no assurances that we will be able to obtain permanent financing for future aircraft deliveries.
      There can be no assurance that our operations will generate sufficient cash flow to make such payments or that we will be able to obtain financing to acquire the additional aircraft necessary for our expansion. If we default under our loan or lease agreements, the lender/lessor has available extensive remedies, including, without limitation, repossession of the respective aircraft and, in the case of large creditors, the effective ability to exert control over how we allocate a significant portion of our revenues. Even if we are able to timely service our debt, the size of our long-term debt and lease obligations could negatively affect our financial condition, results of operations and the price of our common stock in many ways, including:
  •  increasing the cost, or limiting the availability of, additional financing for working capital, acquisitions or other purposes;
 
  •  limiting the ways in which we can use our cash flow, much of which may have to be used to satisfy debt and lease obligations; and
 
  •  adversely affecting our ability to respond to changing business or economic conditions or continue our growth strategy.
      If we need funds and cannot raise them on acceptable terms, we may be unable to realize our current plans or take advantage of unanticipated opportunities and could be required to slow our growth.
We depend on Bombardier to supply us with the aircraft we require to expand.
      As of March 31, 2005, we are obligated under our code-share agreements to place an additional eight CRJ 900 regional jets over the next 6 months. As of March 31, 2005, we have firm orders with Bombardier for an additional 15 regional jets. We also have options to acquire an additional 20 regional jets that are exercisable through 2007 and 40 regional jets that are exercisable in 2010 and beyond.
      We are dependent on Bombardier as manufacturer of these jets and certain factors may limit or preclude our ability to obtain these regional jets, including:
  •  Bombardier could refuse, or may not be financially able, to perform its obligations under the applicable purchase agreement for the delivery of the regional jets; and

31


Table of Contents

  •  a fire, strike or other event could occur that affects Bombardier’s ability to completely or timely fulfill its contractual obligations.
      Any disruption or change in the delivery schedule of these regional jets would affect our overall operations and our ability to fulfill our obligations under our code-share agreements.
      Our operations could be materially adversely affected by the failure or inability of Bombardier or any key component manufacturers to provide sufficient parts or related support services on a timely basis or by an interruption of fleet service as a result of unscheduled or unanticipated maintenance requirements for our aircraft.
Reduced utilization levels of our aircraft under the revenue-guarantee agreements would adversely impact our revenues and earnings.
      Even though our revenue-guarantee agreements require a fixed amount per month to compensate us for our fixed costs, if our aircraft are underutilized (including taking into account the stage length and frequency of our scheduled flights) we will lose the opportunity to receive a margin on the variable costs of flights that would have been flown if our aircraft were more fully utilized.
If we incur problems with any of our third-party service providers, our operations could be adversely affected by a resulting decline in revenue or negative public perception about our services.
      Our reliance upon others to provide essential services on behalf of our operations may result in the relative inability to control the efficiency and timeliness of contract services. We have entered into agreements with contractors to provide various facilities and services required for our operations, including aircraft maintenance, ground facilities, baggage handling and personnel training. It is likely that similar agreements will be entered into in any new markets we decide to serve. All of these agreements are subject to termination after notice. Any material problems with the efficiency and timeliness of contract services could have a material adverse effect on our business, financial condition and results of operations.
We are at risk of losses and adverse publicity stemming from any accident involving any of our aircraft.
      If one of our aircraft were to crash or be involved in an accident, we could be exposed to significant tort liability.
      The estates of the passengers or their estates, of any other future aircraft accident may seek to recover damages for death or injury. Although we believe our present insurance coverage is sufficient, there can be no assurance that the insurance we carry to cover damages arising from any future accidents will be adequate. Accidents could also result in unforeseen mechanical and maintenance costs. In addition, any accident involving an aircraft that we operate could create a public perception that our aircraft are not safe, which could result in air travelers being reluctant to fly on our aircraft. To the extent a decrease is associated with our operations not covered by our code-share agreements, such a decrease could have a material adverse affect on our business, financial condition or results of operations.
If we become involved in any material litigation or any existing litigation is concluded in a manner adverse to us, our earnings may decline.
      We are, from time to time, subject to various legal proceedings and claims, either asserted or unasserted. Any such claims, whether with or without merit, could be time-consuming and expensive to defend and could divert management’s attention and resources. There can be no assurance regarding the outcome of current or future litigation.
Our business would be harmed if we lose the services of our key personnel.
      Our success depends to a large extent on the continued service of our executive management team. We have employment agreements with certain executive officers, but it is possible that members of executive management may leave us. Departures by our executive officers could have a negative impact on our business,

32


Table of Contents

as we may not be able to find suitable management personnel to replace departing executives on a timely basis. We do not maintain key-man life insurance on any of our executive officers.
We may experience difficulty finding, training and retaining employees.
      Our business is labor-intensive, we require large numbers of pilots, flight attendants, maintenance technicians and other personnel and we anticipate that our expansion plans will require us to recruit, train and retain a significant number of new employees over the next several years.
      The airline industry has from time to time experienced a shortage of qualified personnel, specifically pilots and maintenance technicians. In addition, as is common with most of our competitors, we have faced considerable turnover of our employees. Although our employee turnover has decreased significantly since September 11, 2001, our pilots, flight attendants and maintenance technicians often leave to work for larger airlines, which generally offer higher salaries and better benefit programs than regional airlines are financially able to offer. Should the turnover of employees, particularly pilots and maintenance technicians, sharply increase, the result will be significantly higher training costs than otherwise would be necessary. We cannot assure you that we will be able to recruit, train and retain the qualified employees that we need to carry out our expansion plans or replace departing employees. If we are unable to hire and retain qualified employees at a reasonable cost, we may be unable to complete our expansion plans, which could have a material adverse affect our financial condition, results of operations and the price of our common stock.
Risks Related to Our Industry
If competition in the airline industry increases, we may experience a decline in revenue.
      Increased competition in the airline industry as well as competitive pressure on our code-share partners or in our markets could have a material adverse effect on our business, financial condition and results of operation. The airline industry is highly competitive. The earnings of many of the airlines have historically been volatile. The airline industry is susceptible to price discounting, which involves the offering of discount or promotional fares to passengers. Any such fares offered by one airline are normally matched by competing airlines, which may result in lower revenue per passenger, i.e., lower yields, without a corresponding increase in traffic levels. Also, in recent years several new carriers have entered the industry, typically with low cost structures. In some cases, new entrants have initiated or triggered price discounting. The entry of additional new major or regional carriers in any of our markets, as well as increased competition from or the introduction of new services by established carriers, could negatively impact our financial condition and results of operations.
      Our reliance on our code-share agreements with our major airline partners for the majority of our revenue means that we must rely on the ability of our code-share partners to adequately promote their respective services and to maintain their respective market share. Competitive pressures by low-fare carriers and price discounting among major airlines could have a material adverse effect on our code-share partners and therefore adversely affect our business, financial condition and results of operations.
      The results of operations in the air travel business historically fluctuate in response to general economic conditions. The airline industry is sensitive to changes in economic conditions that affect business and leisure travel and is highly susceptible to unforeseen events, such as political instability, regional hostilities, economic recession, fuel price increases, inflation, adverse weather conditions or other adverse occurrences that result in a decline in air travel. Any event that results in decreased travel or increased competition among airlines could have a material adverse effect on our business, financial condition and results of operations.
      In addition to traditional competition among airlines, the industry faces competition from ground and sea transportation alternatives. Video teleconferencing and other methods of electronic communication may add a new dimension of competition to the industry as business travelers seek lower-cost substitutes for air travel.

33


Table of Contents

The airline industry is heavily regulated.
      Airlines are subject to extensive regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, the FAA has issued a number of directives and other regulations relating to the maintenance and operation of aircraft that have required us to make significant expenditures. FAA requirements cover, among other things, retirement of older aircraft, security measures, collision avoidance systems, airborne wind shear avoidance systems, noise abatement, commuter aircraft safety and increased inspection and maintenance procedures to be conducted on older aircraft.
      We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not significantly increase our costs of doing business, to the extent such costs are not reimbursed by our code-share partners.
      The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fail in the future. A decision by the FAA to ground, or require time consuming inspections of or maintenance on, all or any of our aircraft, for any reason, could negatively impact our results of operations.
      In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the use of smaller aircraft at such airports. The imposition of any limits on the use of our aircraft at any airport at which we operate could interfere with our obligations under our code-share agreements and severely interrupt our business operations.
      Additional laws, regulations, taxes and airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce revenues. For instance, “passenger bill of rights” legislation was introduced in Congress in 2001 which would have, among other things, required the payment of compensation to passengers as a result of certain delays and limited the ability of carriers to prohibit or restrict usage of certain tickets. If adopted, these measures could have had the effect of raising ticket prices, reducing revenue and increasing costs. Restrictions on the ownership and transfer of airline routes and takeoff and landing slots have also been proposed. In addition, as a result of the terrorist attacks in New York and Washington, D.C. in September 2001, the FAA has imposed more stringent security procedures on airlines. We cannot predict what other new regulations may be imposed on airlines and we cannot assure you that laws or regulations enacted in the future will not materially adversely affect our financial condition, results of operations and the price of our common stock.
The airline industry has been subject to a number of strikes which could affect our business.
      The airline industry has been negatively impacted by a number of labor strikes. Any new collective bargaining agreement entered into by other regional carriers may result in higher industry wages and add increased pressure on us to increase the wages and benefits of our employees. Furthermore, since each of our code-share partners is a significant source of revenue, any labor disruption or labor strike by the employees of any one of our code-share partners could have a material adverse effect on our financial condition, results of operations and the price of our common stock.
Risks Related to Our Common Stock
Provisions in our charter documents might deter acquisition bids for us.
      Our articles of incorporation and bylaws contain provisions that, among other things:
  •  authorize our board of directors to issue preferred stock ranking senior to our common stock without any action on the part of the shareholders;

34


Table of Contents

  •  establish advance notice procedures for shareholder proposals, including nominations of directors, to be considered at shareholders’ meetings;
 
  •  authorize a majority of our board of directors, in certain circumstances, to fill vacancies on the board resulting from an increase in the authorized number of directors or from vacancies;
 
  •  restrict the ability of shareholders to modify the number of authorized directors; and
 
  •  restrict the ability of stockholders to call special meetings of shareholders.
      In addition, Section 78.438 of the Nevada general corporation law prohibits us from entering into some business combinations with interested stockholders without the approval of our board of directors. These provisions could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders.
Our stock price may continue to be volatile and could decline substantially.
      The stock market has, from time to time, experienced extreme price and volume fluctuations. Many factors may cause the market price for our common stock to decline following this Form 10-Q, including:
  •  our operating results failing to meet the expectations of securities analysts or investors in any quarter;
 
  •  downward revisions in securities analysts’ estimates;
 
  •  material announcements by us or our competitors;
 
  •  public sales of a substantial number of shares of our common stock following this Form 10-Q;
 
  •  governmental regulatory action; or
 
  •  adverse changes in general market conditions or economic trends.
Item 3. Qualitative and Quantitative Disclosure about Market Risk.
      There have been no material changes in the Company’s market risk since September 30, 2004.
Item 4. Controls and Procedures.
      As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company’s disclosure controls and procedures. Disclosure controls and procedures are designed to ensure that information required to be disclosed in the periodic reports filed or submitted under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities Exchange Commission’s rules and forms. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the quarterly period covered by this report but also noted certain weaknesses in the control environment. These weaknesses resulted from recent turnover/advancement of accounting, inventory/purchasing and internal audit personnel and the domination of management by a small group. We continue to dedicate resources to correct these issues and to implement the necessary corrections. Other than these issues, there were no changes in the Company’s internal control over financial reporting known to the Chief Executive Officer or the Chief Financial Officer that occurred during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

      (C) On December 23, 1999, the Board of Directors authorized the repurchase of 10%, or 3.4 million shares, of the Company’s outstanding shares of common stock at the time. On January 4, 2001, October 24, 2002 and October 12, 2004 the Board of Directors amended the original plan and authorized the repurchase of one million, two million and two million additional shares of common stock, respectively. As of March 31, 2005, the Company has acquired and retired 6.8 million shares of our outstanding common stock at an aggregate cost of approximately $40.0 million, leaving 1.6 million shares available for repurchase under the existing Board authorizations, which is open ended. Subsequent to quarter end, the Board of Directors authorized the Company to purchase up to one million additional shares of the outstanding common stock of the Company.
