Capstone Turbine Corporation Announces Third Quarter Fiscal 2009 Operating Results

Third quarter revenue of $11.5 million up 25% from the same period last year. Backlog increased to a record $57.0 million, up 13% from prior quarter and 335% from the same period last year.

CHATSWORTH, Calif.--(BUSINESS WIRE)--February 9, 2009--Capstone Turbine Corporation (www.microturbine.com) (NASDAQ:CPST) today reported operating results for its third quarter ended December 31, 2008 in its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission.

Financial Summary

Capstone’s backlog at the end of the third quarter was $57.0 million, an increase of approximately $6.6 million, or 13%, from the prior quarter and an increase of approximately $43.9 million, or 335%, from the same period last year.

“This quarter we continued our increased production rates and achieved $11.5 million in revenue and over $2.8 million in finished goods in inventory. In addition we had another strong bookings quarter with over $14 million in new orders, despite the overall global market conditions,” stated Darren Jamison, Capstone’s President and Chief Executive Officer. “I am also proud of our achievements in the successful launch of the C1000 product line as this new key product represents 29 megawatts, or 44% of our backlog in megawatts,” added Jamison.

Capstone’s revenue for the third quarter ended December 31, 2008 was $11.5 million, an increase of approximately 25% from the same period last year. Capstone shipped 116 units in the third quarter of Fiscal 2009, compared to 121 units for the same period last year.

The gross loss for the third quarter was $0.6 million, or 5% of revenue, compared to $40,000, or less than 1% of revenue, for the same period last year. The increase in the gross loss and gross loss percentage reflects lower margin product mix, primarily because of the product launch of the C200 and C1000 systems along with an increase in manufacturing expenses, offset by a decrease in warranty expense and higher absorption of overhead costs into ending inventory.

Research and development costs were $2.1 million for the third quarter, an increase of $0.3 million, or 17%, from the same period last year. R&D expenses are reported net of benefits from cost-sharing programs. There were approximately $2.0 million of such benefits this quarter and $0.9 million of such benefits for the same period last year. The overall net increase in R&D expenses resulted from increased spending for supplies, labor, consulting and facility costs offset by additional funding from UTC Power Corporation for the cost-sharing program for the C200 commercialization.

Selling, general and administrative costs were $7.4 million for the third quarter, an increase of $1.0 million, or 16%, from the same period last year. The net increase in SG&A expenses was comprised of an increase in labor, travel, marketing, and professional service expense. The increase in labor and travel costs reflected our continued effort in developing worldwide distributors and launching the C200 and C1000 Series products.


Capstone's net loss was $10.0 million, or $0.06 per share, for the third quarter, an increase of $2.3 million from the $7.7 million loss, or $0.05 per share, reported for the same period last year.

Cash balances decreased by $21.6 million during the third quarter of Fiscal 2009. As of December 31, 2008, cash and cash equivalents were $24.4 million.
