Proofpoint reported in talks to acquire Varonis, sending the shares up more than 10%

Proofpoint, owned by Thoma Bravo, is reported by Bloomberg to be in talks to acquire cybersecurity firm Varonis. No final decision has been made and the talks could end without a deal. Varonis stock was halted after the report and finished up roughly 10% at $46.76. Varonis separately disclosed SaaS annual recurring revenue excluding conversions of $598.1 million, up 25% year over year. No purchase price has been reported.

Thoma Bravo-owned Proofpoint is in talks to acquire Varonis, according to a Bloomberg report published on September 2, 2026. People familiar with the matter said a transaction could be announced in the coming weeks, though no final decision has been made and the talks could still fall apart or draw a competing bidder. The report immediately triggered a sharp rally in VRNS shares, which were halted after the news broke.

Varonis Systems (VRNS) closed up 10.4% at $46.76, buoyed by strong SaaS growth: SaaS ARR excluding conversions rose 25% year-over-year to $598.1 million in the second quarter of 2026, and new-logo annual contract value grew over 20% . The company is also seeing rising adoption of its data and AI security products, including Atlas, Interceptor, and Database Activity Monitoring. Even so, the consensus earnings estimate has remained unchanged over the past 30 days, and a stock's price usually doesn't keep climbing without a trend of upward earnings revisions to back it, which tempers expectations for sustained momentum .

No deal price has been reported. Some outlets have floated a roughly $5.4 billion figure, but that is simply Varonis' market capitalization at the post-rally share price, not a disclosed or confirmed bid; Thoma Bravo's 2021 take-private of Proofpoint itself was valued at about $12.3 billion for comparison. A potential Proofpoint-Varonis combination reflects a broader trend of consolidation among cybersecurity firms, especially those backed by private-equity sponsors like Thoma Bravo, and could create a larger platform combining Proofpoint's email-security capabilities with Varonis' data-protection technology, with potential cross-selling opportunities and expanded market reach.

Investors will be watching for confirmation of the talks, any disclosed deal terms, and regulatory review outcomes if a transaction is announced. Continued strong ARR growth could support a higher purchase price, while the flat earnings-estimate trend may temper how far the stock can run on the acquisition speculation alone. The market's reaction shows confidence in Varonis' growth trajectory, but until a deal is confirmed, this remains a talks-stage report rather than an agreed transaction, and the ultimate outcome will hinge on whether the discussions produce a signed deal.
