April 11, 2014
Ametek is acquiring all outstanding shares of Zygo for a price valued at approximately $280 million.

Ametek (NYSE:AME; Berwyn, PA) is acquiring all outstanding shares of Zygo (Nasdaq:ZIGO; Middlefield, CT) at a purchase price of $19.25 per share in cash, which represents a premium of 31% to Zygo's closing share price on April 10, 2014. The transaction is valued at approximately $280 million, taking into account Zygo's outstanding equity awards and net cash to be acquired in the transaction.

Zygo, founded in 1970, is a provider of optical metrology solutions, high precision optics, and optical assemblies for use in scientific, industrial, and medical applications. In 2013, Zygo had sales of approximately $162 million. The transaction is expected to be completed toward the end of the second quarter of 2014. MAK Capital One, a financial investment advisory firm controlled by Michael A. Kaufman, the Chairman of the Board of Zygo, which owns approximately 23.6% of the outstanding shares of Zygo, as well as Willis, have agreed to vote their shares of Zygo common stock in favor of the merger.

Ametek manufacturers electronic instruments and electro-mechanical devices and had annual sales of $3.6 billion in 2013, up 8% from 2012. Frank S. Hermance, Ametek Chairman and Chief Executive Officer, says, "Zygo's leading position in non-contact optical metrology nicely complements our strength in contact metrology and enables us to offer our customers a full range of metrology solutions."

In 2012 Ametek acquired Technical Manufacturing Corpotation for its vibration isolation systems and optical test benches. Ametek also owns Precitech (Keene, NH), which designs and manufactures ultraprecision machining systems for the single point diamond turning, flycutting, grooving, and milling of optical surfaces, including aspherics, diffractive, and freeform surfaces.
