🔴 Proofpoint Inks $6.3 Billion All-Cash Deal to Acquire Varonis

Proofpoint has agreed to acquire data and AI security firm Varonis in an all-cash deal valued at roughly $6.3 billion, the two companies announced on Thursday.

The deal is the largest cybersecurity acquisition announced so far in 2026.

Varonis shareholders will get $49.75 per share, a 52% premium to the closing stock price of $32.71 on June 22, 2026, the last full trading day before rumors of a potential sale emerged.

The deal is expected to close in the first half of 2027. Thoma Bravo, which owns Proofpoint, is providing committed equity financing and has secured debt financing commitments to fund the acquisition. Ontario Teachers’ Pension Plan is also investing in Proofpoint in connection with the deal.
