FRANKFURT, Germany (AP) — German industrial equipment maker Siemens AG says it has agreed to buy U.S.-based software firm Mentor Graphics Corp. for $4.5 billion.

The companies said in a joint statement Monday that Mentor’s board recommended shareholders approve the deal.

Siemens said it would pay $37.25 a share in cash, or 21 percent more than Mentor’s closing price on Friday.
