Thoma Bravo's Proofpoint to buy Varonis Systems in $6.3 billion all-cash deal

Thoma Bravo-owned cybersecurity firm Proofpoint plans to acquire data security company Varonis Systems through an all-cash transaction worth approximately $6.3 billion, according to Thursday's announcement. In this agreement, Varonis shareholders will receive $49.75 per share in cash, indicating a 52% premium over Varonis' closing stock price on June 22, the day prior to initial speculation about a possible sale.

Reuters had reported in September that Proofpoint was in talks to acquire Varonis Systems. Varonis, based in Miami, provides cybersecurity services such as data classification for cloud storage systems and monitoring employee behavior. The company's shares experienced a 2% increase in extended trading. Earlier this year, in 2021, Thoma Bravo acquired Proofpoint, a software company that aids businesses in defending against cyberattacks, valuing the firm at around $12.3 billion in the private acquisition.
