Broadcom Inc. said Thursday it will buy cloud service provider VMware Inc in a $61 billion cash-and-stock deal to further diversify the chipmaker's business into enterprise software.

Broadcom's shares were up 1.6%, while those of VMWare were down nearly 1% in premarket trading.

The acquisition is the second biggest announced globally so far this year, after Microsoft Corp.'s $68.7 billion deal to buy video game maker Activision Blizzard Inc in January.

News of the deal was first reported Monday.

Each VMware shareholder will get $142.50 per share, resulting in a premium of over 48% to the stock's close since the deal talks were first reported on May 22.

VMware shareholders will get $142.50 in cash or 0.2520 shares of a Broadcom common stock for each VMware share held.
