On December 23, 2025, North American private equity firm Novacap has completed its acquisition of Integral Ad Science, a global media measurement and optimization platform, in an all-cash transaction valued at approximately $1.9 billion ($2.7 billion CAD). Under the agreement, IAS shareholders received $10.30 ($14.73 CAD) per share. The transaction has delisted IAS from the Nasdaq Stock Market, transitioning the company to private ownership. Lisa Utzschneider, CEO of IAS, stated the company will leverage Novacap's resources to enhance its leadership in global media measurement and optimization and provide greater value for customers worldwide. Samuel Nasso, Partner, Technologies, at Novacap, emphasized the firm's commitment to investing in innovation and global scaling while creating transformative value for advertisers and publishers.

Jefferies LLC served as exclusive financial advisor to IAS, with Kirkland & Ellis providing legal counsel. Novacap was advised by Evercore as financial advisor and Willkie Farr & Gallagher LLP as legal counsel. The acquisition positions Novacap to support IAS's continued growth in the digital media quality sector, particularly in AI-powered solutions for trust and transparency in digital advertising.
