Wilson Sonsini Goodrich & Rosati and Morrison & Foerster have scored key advisory roles in the $640 million privatisation of Nasdaq-listed Integrated Silicon Solutions Inc (ISSI) by a consortium of Chinese investors.

The buyer group, led by Summitview Capital, will acquire all of the outstanding shares of ISSI for $19.25 per share in cash. With the closing of the merger, ISSI's operations in Taiwan will either be restructured or sold to comply with Taiwan's laws and regulations.

A Morrison & Foerster team led by Beijing partner Sherry Yin and San Francisco partner Michael O’Bryan is serving as U.S. legal advisor to the buyer. Wilson Sonsini Austin partner Robert Suffoletta and San Francisco partner Robert Ishii are representing ISSI.

ISSI makes integrated circuits for automotive, communications, industrial and digital consumer customers.

The deal, which is expected to close during the third quarter of this year, is subject to approval from ISSI’s investors, as well as antitrust and regulatory approvals.
