Exhibit 99.1 For Immediate Release Contact: Rick DeLisi April 23, 2003 Director, Corporate Communications Page 1 of 5 (703) 650-6550 Atlantic Coast Airlines Holdings, Inc. Reports First Quarter 2003 Financial and Operating Results Dulles, VA, (April 23, 2003) - Atlantic Coast Airlines Holdings, Inc. (Nasdaq/NM: ACAI), parent of Atlantic Coast Airlines (ACA), which operates flights as United Express and Delta Connection in the Eastern and Midwestern United States as well as Canada, announced today that based on accounting principles generally accepted in the United States (GAAP) first quarter net income was $2.0 million ($0.04 per diluted share), compared to first quarter 2002 net income of $14.3 million ($0.31 per diluted share). The company's first quarter 2003 results were affected by the items noted below: - --The company's total number of revenue departures was adversely affected by severe weather conditions and by damaged aircraft. As a result of abnormal winter weather at its Washington Dulles hub and many of the cities served in the Northeastern and Midwestern United States, the company cancelled approximately 3.7% of its scheduled departures in the first quarter, or approximately 2,900 flights due to weather, compared to 1,200 flights during the first quarter last year. In addition, a number of aircraft were damaged, some severely, due to accidents attributed to other parties' operations and to storm conditions. The equivalent of three aircraft were out of service during the first quarter as a result of this damage, two of which are not anticipated to be returned to scheduled service until May. The company estimates that its lost revenue and increased costs relating to unusual weather and aircraft damage reduced pre-tax income by approximately $7.7 million during the quarter. - --The company's earnings for first quarter 2003 were materially affected by the fact that the fee-per-departure rates paid by United Airlines have not been set for 2003, with the result that ACA continues to accrue and receive payment for revenue from United at 2002 rates. Primarily as a result of decreases in scheduled aircraft utilization, the existing rates for 2002 do not adequately compensate the company. Under ACA's agreement with United, rates are to be reviewed each year and modified to reflect changes in costs and developments that have a significant impact. ACA is continuing to pursue discussions with United regarding rates for 2003. The company estimates that the income shortfall in the first quarter resulting from using 2002 departure rates relative to the rates increase it has requested from United was approximately $10 million pre-tax. - --A charge to other expense of $1 million related to a payment to Delta Air Lines to remove contractual restrictions on the use of its ACJet subsidiary and its operating certificate. - --Continued legal costs and contingency planning expenses of approximately $0.4 million in the first quarter as a result of the bankruptcy filings of United Airlines and Fairchild Dornier. - --The company continues to accrue expenses subject to a rate dispute with a vendor related to the power-by-the-hour maintenance contract for certain of the company's regional jet engines. In the first quarter, the company accrued $0.9 million for additional maintenance and potential interest costs in excess of cash payments related to this dispute. Due to the uncertainties surrounding the situation with United and the industry in general, the company previously announced steps to address the current difficulties faced by its partners and the airline industry: - --Based on the unavailability of acceptable financing and other uncertainties facing ACA in the coming months, the company is continuing its discussions with Bombardier to defer certain CRJ deliveries scheduled for 2003 and 2004. In connection with potential changes in its CRJ delivery schedule, the company is reviewing the retirement plan for its fleet of J-41 turboprops, a plan that is subject to change depending on the outcome of the discussions with Bombardier. Changes in the early retirement plan that would keep the J-41s in service for an additional period may result in the company having to reverse amounts previously recorded as early retirement charges. - --The company announced that it has commenced an aggressive cost reduction effort to lower the cost it charges to its major airline partners and to ensure that its costs remain competitive in a difficult revenue environment. The cost reduction effort includes the following: Effective April 1, most salaried employees' base salaries were reduced by 5-10%, and all of the company's bonus plans were eliminated or reduced. These cuts affect the senior management group the most, resulting in an effective reduction of approximately 20- 30% of potential cash compensation. Approximately 330 employees will be subject to a reduction in force in the coming months, including 197 pilots. The pilot furloughs are necessary to bring crew numbers to levels appropriate for current aircraft utilization and changes to the fleet plan now anticipated by the company. Additional cost reduction measures are being implemented including the renegotiation of vendor agreements and a reduction in capital expenditures. During the first quarter 2003, ACA generated approximately 1.1 billion available seat miles (ASMs), an increase of 4.1 percent over the same period last year. The company carried 1,922,609 passengers, an increase of 32.6 percent over the same period last year. Load factor improved 10.9 points to 67.8% for the first quarter compared to 56.9% in the first quarter 2002. Statements in this press release and by company executives regarding its relationship with United Airlines, Inc. and regarding projections and expectations of future aircraft deliveries, availability of financing, future payments by United, operations, earnings, revenues and costs represent forward-looking information. A number of risks and uncertainties exist which could cause actual results to differ materially from these projected results. Such factors include, among others: the extent to which the company accepts regional jet deliveries under its agreement with Bombardier, and its ability to delay deliveries or to settle arrangements with Bombardier regarding undelivered aircraft; United's decision to elect either to affirm all of the terms of the company's United Express Agreement, or to reject the agreement in its entirety, the timing of such decision, any efforts by United to negotiate changes prior to making a decision on whether to affirm or reject the contract, the ability and timing of agreeing upon rates with United, the company's ability to collect pre-petition obligations from United or to offset pre-petition obligations due to United, the company's ability to collect post-petition amounts it believes are due from United for rate adjustments and United's ability to successfully reorganize and emerge from bankruptcy; the continued financial health of Delta Air Lines, Inc.; changes in levels of service agreed to by the company with its code-share partners due to market conditions, and willingness of finance parties to continue to finance aircraft in light of the United situation and of market conditions generally, the ability of these partners to manage their operations and cash flow, and ability and willingness of these partners to continue to deploy the company's aircraft and to utilize and pay for scheduled service at agreed upon rates; availability and cost of product support for the company's 328JET aircraft; whether the company is able to recover or realize on its claims against Fairchild Dornier in its insolvency proceedings and unexpected costs arising from the insolvency of Fairchild Dornier; general economic and industry conditions; additional acts of war; and risks and uncertainties arising from the events of September 11, the impact of the outbreak of Severe Acute Respiratory Syndrome on travel and from the slow economy which may impact the company, its code-share partners, and aircraft manufacturers in ways that the company is not currently able to predict. These and other factors are more fully disclosed under "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in ACAI's Annual Report on Form 10-K for the year ended December 31, 2002.
