               Capstone Turbine Announces Fiscal-Year 2005 Results


           CHATSWORTH, Calif.--(BUSINESS WIRE)--July 6, 2005--Capstone
Turbine Corporation(R) (Nasdaq:CPST) (www.microturbine.com) reported
results for its fiscal year 2005 in its Form 10-K filed with the
Securities and Exchange Commission on June 29, 2005.
           "We are pleased with the progress we made in fiscal 2005 to build
Capstone," said John Tucker, President and CEO of Capstone. "A year
ago, we developed our strategic plan for transitioning Capstone into a
cash flow positive and profitable company. In the first year of
executing on that plan, we made progress in all of our identified
initiatives. Focusing our marketing efforts and growing business in
our targeted markets was one key element of the plan. The growth in
orders, with fiscal 2005 orders more than 190% of the order rate
recorded in fiscal 2004, demonstrates our initial success in
penetrating these targeted markets. This success came in part from our
work to rationalize our channels and to create a more tailored
approach to the targeted markets. In fiscal 2005, approximately 90% of
our sales were still generated by our distributors and dealers."
           Tucker continued, "A key enabling factor to our market success
came from the improvements we made in our product robustness. As a
result of these improvements, we are more confident today that
customers' applications of Capstone MicroTurbines(R) will produce
positive performance for their businesses. The improvements also
resulted in an ability to lower our standard warranty costs by
one-third for new sales. We are very pleased that more than 9 million
operating hours have been accumulated for Capstone MicroTurbines. We
look forward to the continuing growth in the run-time hours for our
products." In announcing Capstone's expanded fuel capabilities for its
C60 microturbines, Tucker said, "We believe the additions we have made
to the operating fuels for our model C60 microturbines, gaseous
propane and compress natural gas, and our expected introduction of a
C60 biogas model in late fall of this year, will provide even greater
appeal to our target markets."
           "Our success has come in part from our expanded market presence,"
said Tony Hynes, Vice President of Sales and Service for Capstone. "In
fiscal 2005, we opened a field service office in Japan to support our
distributors and end users in that region. We also opened sales and
service offices in New York and Italy. Our Italian office, which
serves as our European headquarters, has already reported orders for
fiscal year 2006 of more than 7 megawatts. This represents roughly the
same level of business in Europe, in just over three months in fiscal
2006, as Capstone has received from Europe since its first sales of
microturbines in 1998. We are delighted at the success our regional
presence has delivered." Further, Hynes announced, "As a result of the
success we have had with our local presence, we are opening Capstone
Mexico and are exploring the possibility of an office in Boston. Our
new office in New York has already produced 2.4 megawatts of new
orders since it opened in December 2004. We believe our prospects are
very strong for continuing business growth in the Northeastern United
States."
           Year-to-date orders in fiscal 2006 reported by Capstone were 9.8
megawatts and backlog as of July 6th stands at 17.1 megawatts. "This
level represents more megawatts in backlog today than Capstone shipped
in all of fiscal 2005," said Tucker. "The investments we made in
building our business in fiscal 2005 are already paying off in fiscal
2006. With our tremendous early successes in fiscal 2006, we are
closing in on our targeted sales level for the year. We expect that
further changes we are making in the business, such as our new
National Sales Representative agreement with WESCO Distribution that
we announced earlier today, and additional developments we expect to
announce soon, will provide us even more momentum in our targeted
markets."
           In summarizing Capstone's revisit of its three-year strategic
plan, Tucker said, "We reconfirmed our target markets of CHP/CCHP,
Resource Recovery, Power Reliability and Remote Power when we
revisited our strategic plan. Our approach to our distribution
channels, combining sales through distributors and dealers, as well as
direct sales and lead generation by sales representatives, was also
reaffirmed. Our goals for fiscal 2006 include doubling our sales as
compared with fiscal 2005, reaching a positive gross margin and
reducing our cash burn. We continue to target reaching cash flow
positive in our fiscal year 2007 that ends March 31, 2007."
           Capstone's financial highlights for fiscal 2005 included sales of
$17.0 million, up $4.4 million from $12.6 million reported for fiscal
2004. The majority of the increase in sales reflected higher demand
for the Company's C60 model microturbines. Backlog at the end of
fiscal 2005 was 10.8 megawatts, reflecting backlog at the beginning of
the year of 6.5 megawatts, orders during the period of 20.8 megawatts
and shipments of 16.5 megawatts.
           The reported gross loss was $6.9 million for fiscal 2005, an
improvement of $9.9 million from the $16.8 million loss reported in
fiscal 2004. Lower warranty costs accounted for the change between
periods.
           Operating expenses were $34.2 million for the year, up $2.1
million from the prior year. The higher spending resulted primarily
from higher consulting costs for Sarbanes-Oxley compliance work,
information technology systems developments and market development
activities.
           Capstone's net loss was $39.4 million, an improvement of $8.3
million from the $47.7 million loss reported in fiscal 2004. Fiscal
2005's reported net loss was $0.47 per share as compared with $0.58 a
year earlier.
           Cash usage in the fiscal year was $38.8 million, an increase of
$8.6 million from fiscal year's cash usage of $30.2 million. The
higher cash usage was largely attributable to cash used for inventory
purchases in the current year as opposed to cash sources from
inventory reductions in the prior year.
           Cash and cash equivalents at the end of the year were $63.6
million.
