Xcerra Corporation to be Acquired by Sino IC Capital

Dear Valued Customer,

We are excited to let you know that Xcerra has signed a definitive agreement to be acquired by an affiliate of Sino IC Capital, one of the largest private equity funds in China, for $10.25 per share in cash. I’m writing you to provide details on what this means for you and the future of the Company.

An affiliate of Sino IC Capital has offered to purchase all outstanding shares of Xcerra and our Board of Directors has accepted their offer. This means that, pending regulatory approval and satisfaction of other conditions to closing, Xcerra will become a private company and its shares will no longer trade on the Nasdaq stock exchange.

We do not expect the Company’s change in ownership to have any impact on the day-to-day operations of the company and we do not expect the transaction to change our relationship and commitment to you. We expect Xcerra’s existing management team to continue to run the company and that all company operations will continue as planned. We have always been committed to working under the highest standards to protect our customers’ intellectual property and that commitment will not change as a result of this announcement.

With this transaction, we expect to become a stronger company and be better positioned to support the growth of our customers worldwide. With greater financial backing, Xcerra will be able to focus on innovation and bringing additional products and solutions to our customers. More importantly, with Sino IC Capital’s backing we can potentially target new market segments and move more aggressively to buy companies that complement or enhance our already deep product portfolio.

Our customers should expect business as usual before the deal closes and, just as importantly, after the deal closes, which we expect to be before the end of the calendar year. Upon closing Xcerra will remain a global company headquartered in Norwood, Massachusetts, U.S.A.

We want to thank all of Xcerra’s customers for your continued business as we build an even stronger company to support your semiconductor and electronics manufacturing test requirements. If you have any questions or concerns, do not hesitate to contact your Sales Representatives.

Xcerra Corporation
