IXYS Announces Record Revenues -- 4th Quarter and Fiscal Year Results


    SANTA CLARA, Calif.--(BUSINESS WIRE)--May 24, 2007--IXYS
Corporation (NASDAQ:IXYS) today reported net revenues of $74.0 million
for the fourth fiscal quarter ended March 31, 2007, an increase of
14.9%, as compared with net revenues of $64.4 million for the same
period in the prior fiscal year. This is the fifth quarter of
consecutive revenue growth for the company.

    For the fiscal year ended March 31, 2007, IXYS reported record net
revenues of $285.9 million, an increase of 13.7%, as compared with net
revenues of $251.5 million for the prior fiscal year.

    A power semiconductor company, IXYS develops and markets high
performance power and RF semiconductors and control ICs that are used
to improve power conversion efficiency in a range of applications,
including telecommunication infrastructure, motor drives, medical
systems and transportation. IXYS also serves emerging markets with
digital and analog ICs that control flat panel displays, medical
instruments and telecommunication products (i.e. VoIP).

    Within the renewable energy industry, IXYS supplies chips that
control/regulate high voltages between DC energy (windmills/solar
panels) and AC energy (U.S. electric grid). In addition, IXYS has
developed solar cell arrays and cards for charging portable batteries.

    Highlights for the quarter ended March 31, 2007:

    --  Record revenues of $74.0 million, marking the fifth
        consecutive quarter of revenue growth

    --  Backlog of $105.2 million

    --  Company repurchased about 563,000 shares for $5.2 million

    Highlights for the year ended March 31, 2007:

    --  Record revenues for the fiscal year

    --  Net income rose for the fiscal year, by $34.8 million versus
        the 2006 fiscal year

    --  Company repurchased about 2 million shares for $18.4 million
        for the fiscal year

    Gross profit was $17.9 million, or 24.1% of net revenues, for the
quarter ended March 31, 2007, as compared to gross profit of $20.4
million, or 31.6% of net revenues, for the same quarter in the prior
fiscal year. Gross profit for the fiscal year ended March 31, 2007 was
$84.3 million, or 29.5% of net revenues, as compared to gross profit
of $81.7 million, or 32.5% of net revenues, for the prior fiscal year.
The bankruptcy of All-American Semiconductor, Inc., a large
semiconductor distributor in the U.S., adversely affected gross profit
and net income.

    Net income for the quarter ended March 31, 2007, was $755,000, or
$0.02 per diluted share, as compared to $30.3 million, or $0.85 per
diluted share, for the same quarter in the prior fiscal year. Net
income for the fiscal year ended March 31, 2007, was $28.7 million, or
$0.83 per diluted share, as compared to net loss of $6.1 million, or
$0.18 loss per diluted share, for the prior fiscal year.

    "We have ended our fiscal year with record revenues -- backed by
the strength of our manufacturing strategy and product innovation in
Europe and Asia," said Dr. Nathan Zommer, Chief Executive Officer. "We
continue to introduce products that address the needs of our core
customer markets, while entering developing markets with innovative
products. These developments portend business growth and margin growth
for the long term."

    "Although we stopped shipments to All American prior to their
bankruptcy announcement, we had unpaid receivables at the time of the
bankruptcy filing. While we participate in the legal proceedings to
secure repayment, we must incur a bad debt write-off for the March
2007 quarter. This decision has impacted margins for the quarter and
fiscal year," stated Dr. Zommer. "Additionally, we saw a decline in
margins resulting primarily from excess inventory charges and cyclical
inventory effects inherent in the medical industry."

    "Regardless of these outside influences, we achieved a new record
for revenues while reducing inventory levels from the December 2006
quarter," noted Dr. Zommer. "Fiscal belt-tightening, along with our
consistently strong backlog, gives us confidence that IXYS will return
to margin growth. We expect to improve our long term gross margin as
we invest in R&D to develop and introduce new products, continue to
improve our manufacturing cost structure and reduce our inventory
levels."

    The corporation repurchased 563,000 IXYS shares for $5.2 million
during the March quarter and 2 million IXYS shares for $18.4 million
for the fiscal year ended March 31, 2007. Chief Financial Officer Uzi
Sasson stated, "We plan to continue buying back shares under our
authorized stock buyback program."

    "As we introduce new products to fulfill the needs of our core and
developing customer base, and in light of the All American bankruptcy,
we must build new distributor relationships. We recognize that channel
building will take some time. In that vein, we estimate relatively
flat revenues for the June 2007 quarter as compared to the March 2007
quarter," stated Mr. Sasson.

    ABOUT IXYS

    Since its inception in 1983, IXYS Corporation has been developing
technology-driven products to improve power conversion efficiency.
IXYS is a U.S. pioneer in the development of power semiconductors that
effectively monitor electrical voltage to produce maximum effect with
the least expenditure of energy.

    Diminishing natural resources, demand for cheap energy and
environmental directives for energy efficiency represent a significant
challenge. IXYS' power semiconductors and mixed-signal integrated
circuits can play a vital role in reducing energy costs and
consumption -- as their products regulate the amount of energy
utilized by everyday products. With a customer base of over 3,000
telecommunications, transportation, industrial, medical and consumer
companies, IXYS is a significant provider of power semiconductors in
the U.S.

    A forerunner in the alternative and renewable energy industry,
IXYS focuses on providing power semiconductors for equipment used in
harnessing wind and solar power for conversion to the U.S. electrical
power grid -- one more way to avoid another 2003 blackout. In
addition, IXYS' R&D teams also developed solar cell arrays and cards
for charging portable batteries -- with potential applications for
traditional alkaline batteries, laptops, cell phones, RFID tags and
sensors, to name a few.

    IXYS, and its subsidiary companies, offer a diversified product
base that addresses worldwide needs for power conversion, electrical
efficiency and renewable energy.
