Weiss & Lurie, a national class action and shareholder rights law firm with offices in New York City and Los Angeles, is investigating possible breaches of fiduciary duty and other violations of law by the Board of Directors of FSI International, Inc. (NASDAQ: FSII) arising from its agreement for FSI to be acquired by Tokyo Electron Limited in a transaction valued at approximately $252.5 million. Under the terms of the agreement, FSI’s shareholders will receive $6.20 in cash for each share of FSI stock at closing. The acquisition, expected to close in calendar year 2012, will be completed pursuant to a cash tender offer followed by a second step merger. Weiss & Lurie is investigating whether FSI’s Board acted in the best interests of shareholders in approving this deal. Multiple analysts have set a target price for FSI stock above $6.20, with a high target set at $7.50. Additionally, FSI recently announced its third quarter and first nine months fiscal 2012 financial results reporting a 98 percent sales increase to $50.8 million, compared to $25.6 million for the same period in fiscal 2011. Moreover, FSI’s net income for the first nine months of fiscal 2012 was $10.7 million, as compared to net income of $6.5 million for the first nine months of fiscal 2011.
