ACS Announces First Quarter Fiscal Year 2004 Results

DALLAS, TEXAS — October 21, 2003 — ACS (NYSE: ACS), a leading full-service provider of business process and technology outsourcing solutions, announced today diluted earnings per share of $0.62 for the first quarter ended September 30, 2003. However, these results include approximately $0.02 related to the discontinuance of depreciation and amortization expense of the assets held for sale related to a large portion of our Federal business. Excluding this impact, diluted earnings per share of $0.60 increased 20% compared to $0.50 per share for the same quarter last fiscal year. Revenues increased 17% to $1.037 billion, compared to $882.6 million for the same period last year.

“Our first quarter results were very solid,” said Jeff Rich, ACS’ Chief Executive Officer. “Our revenue exceeded our estimates, internal revenue growth accelerated, and our profit margins were in line. I continue to be very pleased with our new business signings, which represented the third highest in our history. These new signings were anchored by our Gateway win which, in a growing trend, combined business process outsourcing services and information technology outsourcing services. This transaction also includes our third Human Resources outsourcing win in the last nine months. Business momentum remains strong and we look forward to taking advantage of opportunities and addressing challenges during the balance of the fiscal year.”

ACS’ first quarter results include the following key highlights:

• Revenue for the first quarter of fiscal 2004 approximated $1.037 billion and resulted in total revenue growth of 17% when compared to the prior year quarter. Internal revenue growth for the quarter was 15% and exceeded our prior estimate of 13% to 14%. The remaining growth was from acquisitions.

• Diluted earnings per share (including the $0.02 impact from discontinuance of federal government depreciation and amortization) of $0.62 increased 24% when compared to the prior year quarter. Excluding the $0.02 impact, diluted earnings per share increased 20% and was at the high-end of our prior guidance.

• New business signings for the first quarter totaled $149 million of annualized revenue and was the third largest quarter in Company history.

• Cash flow from operations for the first quarter (typically the lowest quarter due to incentive compensation payments) was approximately $59 million. Capital expenditures represented 4.1% of consolidated revenues, or approximately $43 million.

• The Department of Education, which represents approximately 4% of our consolidated revenues, is in the final stages of a competitive procurement for our services. Final bids are due this week and we expect an award to be made in November.

We are also in discussions with senior state officials in Georgia in an attempt to resolve the pending dispute related to implementation delays and payment issues under our Medicaid contract. As of September 30, 2003, ACS has accrued $84.5 million in unbilled receivables under the percentage-of-completion accounting method related to this contract and had $48.1 million of billed receivables, of which $42.8 million was past due. Subsequent to September 30, ACS received $9 million of the past-due amount.

• Pursuant to the Company’s $500 million share repurchase program, as of October 17, 2003, 1.5 million shares have been repurchased, at an average purchase price of $50 per share.

Financial Outlook

Excluding the expected one-time gain associated with the previously announced Federal divestiture, and assuming these transactions are completed effective November 1, 2003, the Company’s financial guidance for the remainder of the fiscal year ending June 30, 2004 is as follows:

• Second quarter revenue is expected to be in a range of $980 million to $1.010 billion. This represents an increase of approximately $35 million from our previous guidance related to an assumed one-month delay of the Lockheed Martin transactions. Diluted earnings per share for the second quarter is expected to range from $0.62 to $0.64 per share, excluding any impact related to the planned divestiture.

• Third quarter revenue is expected to be in a range of $1.025 billion to $1.065 billion. Diluted earnings per share for the third quarter is expected to range from $0.67 to $0.70 per share.

• Fourth quarter revenue is expected to be in a range of $1.115 billion to $1.185 billion. Diluted earnings per share for the fourth quarter is expected to range from $0.69 to $0.72 per share.

• Our third and fourth quarter financial outlook remains unchanged from the guidance given in August 2003.

• Total fiscal year 2004 revenues are expected to be in a range of approximately $4.15 billion to $4.3 billion.

• Excluding the expected one-time gain from the anticipated sale of a large portion of our Federal segment and the related benefit of lower depreciation and amortization of the related assets, fiscal year 2004 diluted earnings per share is expected to be in a range from $2.58 to $2.66.

• The Company estimates its effective tax rate to be 37.5% for fiscal year 2004.

Statements about the Company’s outlook and all other statements in this release other than historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements and all references to financial estimates rely on a number of assumptions concerning future events and are subject to a number of uncertainties and other factors, many of which are outside the Company’s control, that could cause actual results to differ materially from such statements. While the Company believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in predicting certain important factors, especially the finalization of the pending divestiture and acquisition transactions discussed above; the timing and magnitude of technological advances; the performance of recently acquired businesses; the prospects for future acquisitions; the possibility that a current customer could be acquired or otherwise be affected by a future event that would diminish their information technology and business process services requirements; the competition in the information technology industry or business process services business and the impact of such competition on pricing, revenues and margins; the degree to which business entities continue to outsource information technology and business processes; uncertainties surrounding budget reductions or changes in funding priorities or existing government programs and the cost of attracting and retaining highly skilled personnel.

These factors, when applicable, are discussed in the Company’s filings with the Securities and Exchange Commission, including the most recent Form 10-Q and Form 10-K, a copy of which may be obtained through the Company without charge. ACS disclaims any intention or

obligation to revise any forward-looking statements, including financial estimates, whether as a result of new information, future event, or otherwise.

Use of Non-GAAP Financial Information

The Company reports its financial results in accordance with GAAP. However, the Company uses certain non-GAAP performance measures, including free cash flow and internal revenue growth, to provide both management and investors a more complete understanding of the Company’s underlying operational results.

These non-GAAP measures are indicators management uses to provide additional meaningful comparisons between current results and prior reported results, and as a basis for planning and forecasting for future periods. For example, the Company believes free cash flow provides another measure of cash flow available for operations, after the Company has satisfied the capital expenditure requirements of its operations. In the consolidated statements of cash flow, the Company reports year-to-date net cash provided by operating activities (cash flow from operations) and capital expenditures (purchases of property, equipment and software, net of sales), and does not adjust those reported amounts in deriving the measure of free cash flow. This measure of free cash flow may not be comparable to similarly titled measures of other companies. The Company uses the calculation of internal revenue growth to measure the revenue growth of the Company excluding the acquired revenue from acquisitions. The Company determines acquired revenues based on pre-acquisition normalized revenues of acquired companies. The presentation of this additional information is not meant to be considered in isolation or as a substitute for comparable metrics prepared in accordance with GAAP in the United States.
