Alpha and Omega Semiconductor Intends to Exercise an Option to Acquire a Wafer Fabrication Facility From Integrated Device Technology

August 27, 2011

SUNNYVALE, Calif., Aug. 27, 2011 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited ("AOS") (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors, today announced that it intends to exercise an option to acquire certain assets associated with a 200mm wafer fabrication facility from Integrated Device Technology, Inc. ("IDT") (Nasdaq:IDTI). Under the existing foundry service arrangement with IDT, AOS has the option to acquire these assets for $26 million, and the option is exercisable between September 1, 2011 and November 15, 2011. AOS expects to exercise this option before the November 15, 2011 deadline.

"We believe that this acquisition will allow us to accelerate revenue growth and increase gross margin significantly through faster introduction of high-value products and expansion into new serviceable available markets (SAMs)," said Dr. Mike Chang, Chairman and CEO of AOS. "The expected acquisition of this wafer fabrication facility will enable us to transition from our current fabless business model to a "fab-lite" model to support our expected growth beyond the current level. Other benefits that we expect include quicker response to customer demands and enhanced relationships with strategic customers."   

"We initiated our relationship with IDT under a foundry service arrangement, and through close collaboration, we were able to transfer certain products to, as well as develop new technologies at, the IDT facility. Accordingly, we believe that the production ramp-up period following the acquisition would be shortened as we are already receiving production wafers in low volume from IDT," said Ephraim Kwok, CFO of AOS. "After the initial ramp-up period, we expect our gross margin to improve significantly over time as compared to our gross margin under the existing fabless model; however, during the first two to three quarters of the ramp-up period, we expect our gross margin to decline temporarily. We also believe that this new fab-lite model will give us flexibility in capacity management and geographic diversification of our wafer supply chain."

AOS is committed to accelerating technology and product development to rapidly grow revenue and improve gross margin, and today's announcement represents an important milestone in this commitment. Under the fab-lite model, AOS intends to allocate its wafer manufacturing requirement between its internal facility and outsourced capacity. This fab-lite model is consistent with the model adopted by other successful semiconductor companies.

The acquisition is subject to the execution of a definitive asset purchase agreement with customary closing conditions between AOS and IDT. AOS currently expects to sign the asset purchase agreement by the end of calendar year 2011 and close the transaction prior to January 31, 2012.
