Exhibit 99.1 Capstone Turbine Corporation Announces Third Quarter Fiscal 2007 Operating Results Revenue of $5.7 Million up 97% from Prior Quarter. Gross Loss Improves to 8%. CHATSWORTH, Calif.--(BUSINESS WIRE)--Feb. 9, 2007--Capstone Turbine Corporation (Nasdaq:CPST) (www.microturbine.com) reported operating results for its third quarter ended December 31, 2006 in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on February 9, 2007. Financial Summary Capstone's backlog at the end of the third quarter was $8.1 million, an increase of 19% from the prior quarter, although decreased over 19% from the prior year comparable quarter. "Notably, orders booked during the third quarter were $5.9 million or 6.2 megawatts exceeding orders for each of the last five quarters," said Darren Jamison, Capstone's President and CEO. Revenue for the fiscal 2007 third quarter was $5.7 million, an increase of approximately 97% from the prior quarter and a decrease of approximately 19% from the prior year comparable quarter. The reported gross loss for the third quarter was $0.5 million, or 8% of revenue, improved, when compared to $2.8 million, or 39% of revenue from the prior year comparable quarter and $2.3 million, or 79% of revenue from the prior quarter. The improvement in the gross loss and corresponding gross loss percentage reflects higher volume, improved product mix and decreasing manufacturing expense. Research and development costs were $2.0 million for the fiscal 2007 third quarter, an improvement of $1.1 million, or 35%, from the prior year comparable quarter and $0.6 million, or 23% from the prior quarter. The improvement was primarily related to reduced payroll, consulting and development hardware costs as well as increased contract recoveries. Selling, general and administrative costs were $6.4 million for the fiscal 2007 third quarter, an improvement of $2.6 million, or 29%, from the prior year comparable quarter, of $9.0 million. The decrease from the prior year comparable quarter is primarily attributable to lower marketing, payroll, professional fees and legal settlement costs offset by approximately $0.3 million of increased non-cash stock compensation charges related to the Company's adoption of SFAS 123(R). Selling, general and administrative costs increased $0.3 million, or 5% from the prior quarter. The increase from the prior quarter is due to executive hiring costs and increased facilities costs offset by decreased administrative costs associated with our Annual Shareholders Meeting and Proxy Statement distribution. Capstone's net loss was $8.5 million for the fiscal 2007 third quarter, or $0.08 per diluted common share, an improvement of $1.9 million from the $10.4 million loss, or $0.10 per diluted common share, reported for the second quarter of fiscal 2007. Cash balances decreased by $13.8 million during the third quarter of fiscal 2007. The cash decrease consisted primarily of the $8.5 million net loss and changes in working capital of $6.1 million. The changes in working capital were primarily the result of higher accounts receivable as a result of the increased sales in the quarter and decreased accounts payable and accrued expenses. As of December 31, 2006, cash and cash equivalents were $25.5 million. On January 24, 2007 the company closed its equity offering announced on January 19, 2007, providing net cash proceeds of approximately $42.4 million.
