Aspen Technology Announces Financial Results for First and Second Quarters of Fiscal 2005

March 15, 2005

CAMBRIDGE, Mass.--(BUSINESS WIRE)--March 15, 2005--Aspen Technology, Inc. (Nasdaq: AZPNE), the leading provider of software and services to the process industries, today reported financial results for its quarters ended September 30, 2004 and December 31, 2004, the first two quarters of fiscal 2005. Additionally, the Company announced in a separate press release that the Audit Committee of the Company's Board of Directors has completed its previously announced investigation and that the Company has restated its financial results for each of the fiscal years ended June 30, 2000 through June 30, 2004.

Total revenues for the quarter ended September 30, 2004 totaled $63.3 million, with software license revenues of $25.3 million and services revenues of $38.0 million. On a generally accepted accounting principles in the United States (GAAP) basis, the Company reported a net loss for the quarter of $33.6 million, or $0.80 per diluted share, which included restructuring charges and FTC legal costs of $21.5 million. On a non-GAAP basis, excluding these charges, litigation defense and settlement costs, the gain on the sale of the AXSYS product line, amortization of intangibles, and preferred stock dividend and discount accretion, the Company reported a loss of $3.7 million, or $0.04 per diluted share, for the quarter ended September 30, 2004.

Total revenues for the quarter ended December 31, 2004 totaled $71.6 million, with software license revenues of $36.7 million and services revenues of $34.9 million. The Company more than doubled the number of software license transactions of approximately $1 million or greater from the preceding quarter. On a GAAP basis, the Company reported a net loss for the quarter of $6.7 million, or $0.16 per diluted share. On a non-GAAP basis, excluding restructuring charges and FTC legal costs, fees related to the Audit Committee review, litigation defense and settlement costs, one-time contract termination costs, amortization of intangibles, and preferred stock dividend and discount accretion, the Company reported net income of $3.3 million, or $0.04 per share, for the quarter ended December 31, 2004.

"The sequential rebound of our software license revenues during the December quarter was significant given the multiple challenges facing the Company, and we believe it demonstrates AspenTech's strategic position within process manufacturers," said Mark Fusco, President and Chief Executive Officer of Aspen Technology. "With the completion of our settlement with the FTC and our restatement of financial results, our entire management team is finally in a position to focus all of its efforts on executing our business strategy. My top priority as the new CEO of AspenTech is now to improve the Company's operations so that we can deliver on the potential of our aspenONE solutions for the Enterprise Operations Management market. We will concentrate our efforts on better serving our customers, which we believe will enable us to grow our revenues and improve our profitability over time."

Focus on Integrated Solutions

"We are focused on taking advantage of the momentum initiated at our AspenWorld Conference in October 2004," said Fusco. "The feedback from our customers has been very positive about the launch of aspenONE, the first comprehensive set of software solutions for the Enterprise Operations Management market. Our aspenONE solutions provide process manufacturers with integrated systems designed to optimize their efficiency and profitability across the process manufacturers' global enterprises.

"We are now able to offer a unique value proposition and a significant return on investment based on solutions that support our customers' integrated business processes. I am confident in the long-term direction of AspenTech given the interest shown in aspenONE, the continued strength of our customers' businesses, our new solutions, and our continuing implementation of new initiatives to improve our internal business processes and execution."

During the first six months of fiscal 2005, AspenTech signed significant software license agreements with BP, Bayer, Bechtel, DSM, Fluor, Owens Corning, Pfizer, and Solutia. Approximately 70% of the Company's software license revenue during that period was associated with the Company's engineering solutions. Licenses with companies in the petroleum industry and engineering and construction industry made the most significant contributions to the Company's software revenue performance in the first six months of the fiscal year.

Improved Cost Structure

During the second quarter of fiscal 2005, the Company's management continued efforts to reduce the Company's expense infrastructure. On a GAAP basis, the Company's total expenses were $76.3 million. On a non-GAAP basis, excluding restructuring charges and FTC legal costs, fees related to the Audit Committee review, litigation defense and settlement costs, one-time contract termination costs, amortization of intangibles, and preferred stock dividend and discount accretion, the Company's total expenses were $69.9 million, down $2.9 million from last year. Management believes it will be able to leverage its improved operating model to improve the Company's profitability over the next twelve to eighteen months.

"We have worked diligently to put the Company in a position to drive significantly improved levels of profitability," said Charles Kane, Senior Vice President and Chief Financial Officer of Aspen Technology. "We are continuing to evaluate ways to capture organizational efficiencies by eliminating excess facilities charges and improving our business processes and organizational efficiency. A major focus of the Company for the remainder of the year will be to strengthen our balance sheet further, which has already improved dramatically over the past 18 months, with our increase in cash and decrease in debt."

Customer Service Award

During the quarter ended December 31, 2004, AspenTech received a Hall of Fame lifetime achievement award from the Service and Support Professionals Association (SSPA) as a result of the Company's receipt of a fifth straight "STAR" award for delivering outstanding customer service. This achievement recognizes that AspenTech has consistently delivered world-class technical support and customer service, and reflects the Company's commitment to continuously improving its support offerings. AspenTech believes that its ability to help customers capture value with complex solutions and outstanding customer support continues to be an important competitive differentiator in the marketplace.
