Mentor Graphics (MENT) to be acquired by Siemens AG for $4.5 billion

Siemens AG agreed to buy Mentor Graphics Corp. for $4.5 billion in its biggest acquisition since 2014 as the German engineering company extends its industrial software capability.

   

Siemens will pay $37.25 a share in cash for Wilsonville, Oregon-based Mentor, the industrial giant said in a statement on Monday. That’s 21 percent above the closing price on Friday. Elliott Management Corp., which owns 8.1 percent of Mentor’s shares, backs the offer, Siemens said.

The deal follows Siemens’s $970 million January purchase of U.S. computer-program maker CD-adapco of the U.S. as Chief Executive Officer Joe Kaeser seeks to grow the digital business as part of a retreat from consumer-oriented products to focus on industrial applications. Mentor is the biggest acquisition announced by the Munich-based company since it agreed to buy Dresser-Rand Group Inc. for $7.6 billion. For its part, Mentor was under pressure to increase shareholder value from activist investor Elliott, which doubled its stake in September.
