Polycom is to be bought for $2bn by private-equity firm Siris Capital Group, after it announced it has ended the previously announced $1.9bn deal with Canadian telecommunications company Mitel Networks Corp.
Siris Capital is to pay $12.50 per share for Polycom, valuing the company at about $2 billion.
Both Mitel and Polycom saw their share price jump after the deal was cancelled. Polycom shares rose 13.1% and Mitel shares rose 22%.
The Siris deal values Polycom at $11 a share, when the Mitel deal was announced, it valued Polycom at $13.44 a share.
Polycom will pay Mitel a termination fee of $60 million.
"We are very excited for the opportunity to partner with Polycom and its leadership team, as the Company fits well with Siris' investment focus on mission-critical telecommunications businesses," said Dan Moloney, executive partner at Siris, in a statement Friday.
Siris added that it wants to use Polycom's audio and video collaboration to move into a cloud-based environment.
"While I am disappointed that this particular transaction will not move forward, I am confident in Mitel's future as an industry leader and as a market consolidator," said Rich McBee, president and CEO of Mitel in a Friday statement.
In May, Polycom disclosed it had received an offer from a then-unnamed private-equity firm. On July 7, Polycom received a higher offer, and Mitel declined to renegotiate.
