FGS Global represents Zendesk as the San Francisco-based customer engagement software company acquired by Hellman & Friedman and Permira investment firms in a $10.2B deal.

Zendesk, in February, rejected a $17B takeover offer from a group of equity firms that included H&F and Permira.

It called that bid a" non-binding proposal significantly undervalues the Company and is not in the best interests of the Company and its shareholders."

The Company, which is being squeezed by activist firm Jana Partners, reviews the revised offer as a way to "executive on our long-term strategy with our customers as our top priority," according to Mikkel Svane, Zendesk's founder/chairman/CEO.

The $77.50 per-share offer represents a 34 percent premium over Zendesk's June 23 closing stock price.

FGS Global's John Christiansen and Zachary Tramonti handle Zendesk.
