Aspen Technology Reports Fourth Consecutive Quarter of Software License Revenue Growth

April 29, 2004
Company Delivers Significant Improvement in Year-over-Year Operating Margins Driven by Rebound in Spending From the Chemicals Market

CAMBRIDGE, Mass.--(BUSINESS WIRE)--April 29, 2004-- Aspen Technology, Inc. (NASDAQ: AZPN) today reported financial results for its fiscal 2004 third quarter and nine months ended March 31, 2004.

Total revenues for the third quarter totaled $80.7 million, with software license revenues of $35.9 million and services revenues of $44.8 million. On a Generally Accepted Accounting Principles (GAAP) basis, the company reported third quarter net income of $1.5 million, or $0.03 per diluted share, compared to a net loss of $2.0 million, or ($0.05) per diluted share, in the same period last year. On a pro forma (non-GAAP) basis, excluding the preferred stock dividend and discount accretion, the company reported fiscal 2004 third quarter net income of $4.9 million, or $0.06 per diluted share.

"The strength of our business in the chemicals and oil & gas industries, combined with continued operational execution, enabled us to meet or exceed our quarterly targets for revenue and net income for the sixth consecutive quarter," said David McQuillin, President and CEO of AspenTech. "We continue to see modest improvements in the global economic environment and our customer base is actively looking to invest in IT solutions that support their corporate-wide initiatives to improve operational performance.

"During the past nine months, we have released nine new products, which we believe will fuel our future growth. Now, our challenge as a company is to focus on capturing the growth opportunities of these new products, as well as maximize the performance of our existing point solutions. As we build our sales pipeline for these products, we plan to reallocate organizational resources into sales and marketing activities that support our plans for profitable, sustainable growth in fiscal 2005 and beyond."

Total revenues for the nine months ended March 31, 2004 were $238.1 million, with software license revenues growing by approximately seven percent year-over-year to $108.7 million and services revenue totaling $129.4 million. On a GAAP basis, the company reported net income of $6.4 million, or $0.13 per diluted share, as compared to a net loss of $151.8 million, or ($3.96) per diluted share, for the same period last year. On a pro forma (non-GAAP) basis, excluding the preferred stock dividend and discount accretion, the company reported net income of $9.3 million, or $0.12 per diluted share, compared to a pro forma (non-GAAP) loss of $7.7 million, or ($0.20) per diluted share, in the prior year.

"The company has made significant strides in consistently meeting or exceeding our operational targets and improving our financial performance, as evidenced by the year-over-year increase in our operating margins," said Charles Kane, Senior Vice President & CFO. "As we seek to grow our revenues and hit our long-term operating margin goals, it is necessary to maintain our focus on operational improvement and invest in the areas of the business that will produce the greatest growth opportunities."

AspenTech accomplished the following in the third quarter:

-- Generated 6.6 percent operating margins, its highest quarterly operating margin in four years and a more than two-fold improvement from last year's third quarter.

Pro Forma (non-GAAP) Results

AspenTech reports pro forma financial results, which exclude certain non-operational, non-cash and other specified charges that management generally does not consider in evaluating the Company's ongoing operations. These results are provided as a complement to results provided in accordance with accounting principles generally accepted in the United States (known as "GAAP"). Management believes this pro forma measure helps indicate underlying trends in the Company's business, and uses this pro forma measure to establish budgets and operational goals that are communicated internally and externally, to manage the Company's business and to evaluate its performance.
