DANBURY, Conn., April 15, 2014 (GLOBE NEWSWIRE) -- ATMI, Inc. (Nasdaq:ATMI), a global technology company, announced that shareholders overwhelmingly approved its proposed merger with Entegris, Inc. (Nasdaq:ENTG) for $34 per share in cash at today's special shareholders' meeting.

Approximately 99.3 percent of the votes cast, representing 82.2 percent of the ATMI common shares outstanding as of the record date, voted in favor of the merger. Adoption of the merger agreement required an affirmative vote of a simple majority of the ATMI common shares outstanding.

Approval from the Taiwan Fair Trade Commission is the only required regulatory approval for the merger that remains outstanding. We currently expect to receive this approval by the end of April 2014 and, subject to the satisfaction of the other conditions to closing, expect to close the merger promptly thereafter in accordance with the terms of the merger agreement.

During the special meeting, shareholders also approved a proposal to adjourn the special meeting, if necessary, to solicit additional proxies if there were insufficient votes at the time of the special meeting to adopt the merger agreement; and a non-binding advisory proposal to approve the golden parachute compensation payable to ATMI's named executive officers in connection with the merger.
