CAPSTONE TURBINE ANNOUNCES 1ST QUARTER 2006 RESULTS

CHATSWORTH, Calif., August 10, 2005 (BUSINESS WIRE) -- Capstone Turbine
Corporation(R) (Nasdaq:CPST) (www.microturbine.com) reported results for the
first quarter of fiscal year 2006 on Form 10-Q filed with the Securities and
Exchange Commission on August 9, 2005.

Backlog increased to 15.5 megawatts at quarter-end, up 94% from the prior year
comparable quarter, and sequentially up 44% from the fourth quarter.

FINANCIAL SUMMARY

Capstone's financial results for the first quarter of fiscal 2006 included
revenue of $3.8 million, down $1.6 million from $5.4 million reported for the
fourth quarter of fiscal 2005. The majority of the decrease was due to staging
of approximately $1.5 million of finished product for rapid response to the New
York market. Additionally, approximately $0.6 million in revenue was delayed
pending payments from certain international customers.

Backlog at the end of the first quarter of fiscal 2006 was 15.5 megawatts,
consisting of backlog at the beginning of the quarter of 10.8 megawatts, orders
during the quarter of 8.1 megawatts and shipments of 3.4 megawatts.

The reported gross loss was $3.4 million for the first quarter of fiscal 2006,
an increase of $1.6 million from the $1.8 million loss reported in the fourth
quarter of fiscal 2005. The primary reason for the change between periods
resulted from a benefit of $1.6 million recorded in the prior quarter, and $0.6
million expense in the current quarter, or a net $2.2 million change in gross
profit.

Operating Costs and Expenses were $7.9 million for the quarter, down $0.7
million from the prior quarter, primarily due to $0.9 million of benefits
reported from the Department of Energy (DOE) cost sharing programs in the
current quarter.

Capstone's net loss was $10.9 million, an increase of $0.9 million from the $10
million loss reported in the fourth quarter of fiscal 2005. The first quarter of
fiscal 2006 reported net loss was $0.13 per share as compared with $0.12 the
previous quarter.

Cash usage in the first quarter was $11.6 million, a decrease of $0.6 million
from the prior quarter's cash usage of $12.1 million. The lower cash usage was
attributable to less cash used in investing activities and lower operating cash
usage.

Cash and cash equivalents at the end of the quarter were $52 million.
