3. Synnex Acquires Westcon Americas

Head count: 4,271 employees (all of Westcon)

Annual sales: $2.18 billion

Purchase price: $830 million

Date of announcement: June 6

Synnex will burst onto the Cisco scene by purchasing Westcon-Comstor's North American and Latin American businesses.

The Fremont, Calif.-based distributor will also take a 10 percent stake in Westcon-Comstor's International business, which includes Europe, the Middle East and Africa, and Asia-Pacific. Synnex will have the option to acquire an additional 10 percent interest in Westcon International for another $30 million.

Synnex had been the only North American broadline distributor not carrying Cisco, while 44 percent – or $2.16 billion – of Tarrytown, N.Y.-based Westcon's sales come from its Cisco-exclusive Comstor business. The acquisition is expected to close in the third quarter of 2017.
