Company Approved to Relist on NASDAQ Stock Market

Burlington, Mass - Aspen Technology, Inc. (NASDAQ: AZPN, as of February 10, 2010) a leading provider of software and services to the process industries, today announced its financial results for its second quarter of fiscal 2010, ended December 31, 2009.

Mark Fusco, Chief Executive Officer of AspenTech, said, "We are pleased with the company's performance in the second quarter, as solid transaction flow drove product-related bookings of approximately $95 million. Within product related bookings, the license portion was consistent with the year ago period. Early customer response to our new aspenONE licensing model has been very favorable, which is driving both renewal activity and expanded usage with customers across each of our target markets. As we look to the second half of our fiscal year, customer interest levels remain high and we are encouraged by the positive impact of our new aspenONE licensing model on both our competitive position and long-term market opportunity."

Fusco added, "After bringing our financial statements current with the filing of our first quarter results and subsequently filing our second quarter results in a timely manner, we have been approved to relist the company‘s common stock on the NASDAQ stock market effective tomorrow morning under the ticker 'AZPN'. We are excited to complete this process so that investors can focus exclusively on AspenTech's business performance, strong competitive position and market opportunity."

AspenTech's total revenue of $42.7 million decreased from $82.6 million in the second quarter of the prior year, due primarily to the ratable revenue recognition associated with the company's new aspenONE licensing model.

• Subscription revenue includes all revenue associated with the company's new aspenONE licensing model. Subscription revenue was approximately $1.2 million in the second quarter of fiscal 2010. No subscription revenue was recorded in the year ago period as the company's new aspenONE licensing model was launched during the first quarter of fiscal 2010. Subscription revenue is recognized over the course of the multiyear agreement, and recognition begins when the first payment is due, which is typically 30 days after the contract is signed.
• Software revenue includes all non-subscription-based license revenue, including term-based contracts for point products as well as perpetual licenses. Software revenue was $9.0 million in the second quarter of fiscal 2010, compared to $47.3 million in the year ago period. In fiscal year 2010, software revenue related to term contracts is recognized over the contract term, generally as payments become due. In prior fiscal year periods, the company predominantly recognized term license revenue on an up-front basis, and what was previously categorized as license revenue typically equaled license bookings. However, in the second quarter of fiscal year 2009, license revenue was approximately $17 million lower than license bookings as a result of certain license bookings not meeting the criteria for up-front revenue recognition.
• Services & other revenue, which includes professional services, maintenance and other revenue, was $32.5 million in the second quarter of fiscal 2010, a decrease compared to $35.4 million in the year ago period. The year-over-year decline was primarily a result of the more challenging economic environment compared to the year ago period. Services and other revenue was up sequentially compared to $28.7 million in the first quarter of fiscal 2010.

For the quarter ended December 31, 2009, AspenTech reported a loss from operations of $29.3 million due primarily to the ratable revenue recognition associated with the company's new aspenONE licensing model. For the quarter ended December 31, 2008, the company reported income from operations of $18.8 million. Net loss was $30.7 million in the second quarter of fiscal 2010, leading to net loss per basic and diluted share of $0.34 compared to net income per diluted share of $0.25 in the same period last year.

AspenTech had a cash balance of $109.4 million at December 31, 2009, compared to $109.0 million at the end of the first quarter of fiscal 2010. The company did not sell any installments receivable to raise cash during the second quarter of fiscal 2010 and it continued to reduce its secured borrowings balance, which was $96.5 million at the end of the quarter, down $12.3 million compared to $108.8 million at the end of the first quarter of fiscal 2010.
