Proofpoint to Acquire Varonis in $6.3 Billion All-Cash Deal

Proofpoint, Inc., a portfolio company of Thoma Bravo, announced on October 15, 2026, that it has entered into a definitive agreement to acquire Varonis Systems, Inc. in an all-cash transaction valued at approximately $6.3 billion. The deal combines two cybersecurity firms to create a platform focused on data and AI security.

Transaction Terms and Valuation

Under the terms of the agreement, Varonis shareholders will receive $49.75 per share in cash. According to the companies, this purchase price represents a premium of 52% to Varonis’ closing stock price of $32.71 on June 22, 2026, which was the last full trading day prior to initial rumors about a potential sale. It also represents a premium of 17% over Varonis’ closing stock price of $42.35 on September 1, 2026, the last trading day prior to additional media reports speculating about a sale.

The transaction values Varonis at approximately 53x LTM Free Cash Flow and 8.4x LTM Revenue. Thoma Bravo is providing committed equity financing and has secured debt financing commitments to fund the purchase. Ontario Teachers’ Pension Plan has also agreed to make an investment into Proofpoint in connection with the transaction.

Strategic Rationale

The combined company intends to deliver a unified platform designed to help organizations adopt AI by finding and protecting sensitive data, controlling access for people and AI, and stopping data loss. Proofpoint describes itself as a global leader in human and agent cybersecurity, while Varonis is described as a data and AI security leader.

"As AI becomes embedded across the enterprise, the data it can access determines both its value and its risk," said Sumit Dhawan, CEO of Proofpoint. "By connecting communications, identities, permissions, data, and AI, we are creating an intelligence advantage that helps customers see risk more clearly, respond faster, and defend against the next generation of AI risks."

Yaki Faitelson, Varonis CEO, Co-Founder and Chairman of the Board of Directors, stated, "Our mission is to secure AI and the data that powers it. By joining forces with Proofpoint, we can achieve this mission faster than ever."

Closing Conditions and Timeline

The transaction has been unanimously approved by the Varonis Board of Directors and is expected to close in the first half of 2027. Completion is subject to customary closing conditions, including approval by Varonis shareholders and receipt of regulatory approvals. Until the transaction closes, Proofpoint and Varonis will continue to operate as separate and independent companies. Upon completion, Varonis' common stock will cease trading on the Nasdaq, and Varonis will become a private company.

Varonis will announce its financial results for the third quarter 2026 following the close of the U.S. financial markets on November 3. In light of the announced transaction, Varonis will not conduct an earnings conference call.

Why it matters

This acquisition consolidates two significant players in the cybersecurity sector, creating one of the world’s leading pure-play cybersecurity companies. The deal highlights the growing industry focus on securing AI workflows and data access as AI agents become more prevalent in enterprise environments. For Varonis shareholders, the deal offers an immediate cash exit at a significant premium to pre-rumor stock prices.
