SHANGHAI, China, May 31, 2011 (GLOBE NEWSWIRE) -- BCD Semiconductor
Manufacturing Limited ("BCD Semiconductor") (Nasdaq:BCDS), a leading
analog integrated device manufacturer, or IDM, based in China,
specializing in the design, manufacture and sale of power management
integrated circuits, or ICs, today announced that it has acquired
Auramicro Corporation, a private company incorporated in Cayman Islands
with main operations in Taiwan, for approximately $5.6 million in cash.
The acquisition will add a significant engineering team to BCD's power
management IC research and development team. In addition, the
acquisition will expand BCD's rapidly growing DC/DC product portfolio
with solutions that can leverage BCD's Fab 2 manufacturing process
currently under development.

"The addition of Auramicro's analog design team and power IC product
portfolio will be a great complement to BCD's growing power IC
business," said Chieh Chang, CEO of BCD Semiconductor. "We feel our
differentiated business model will allow us to continue to take share
in the multi-billion dollar power IC market and we are excited to have
Auramicro's team join the BCD family."

The transaction is expected to close by the end of the second fiscal
quarter of 2011. The acquisition, which initially adds approximately
$500 thousand in operating expenses per quarter, is expected to be
neutral to BCD's earnings per share in the company's 2011 fiscal year
and accretive in 2012.
