Integral Ad Science (US45828L1089) joined the Originator Profile consortium on October 2, 2026, linking its Japanese business to a project designed to create verifiable web standards. As PR Times reported, the initiative is intended to help users identify verified content creators and advertising sources.

What the standards move means

The Originator Profile consortium was established on December 15, 2022, and is working on specifications and trial implementations for a web standard. IAS Japan is listed among its corporate members alongside media, advertising and technology companies, according to PR Times.

The business connection is direct: Integral Ad Science provides media measurement, fraud detection, brand safety and viewability tools for advertisers, publishers and media platforms. The October 2, 2026 initiative therefore extends the company's established emphasis on transparency into content provenance and publisher verification.

The private-market valuation

Multiples reports that Novacap acquired Integral Ad Science for USD 1.9 billion on September 24, 2025, with the transaction closing on December 23, 2025. The disclosed valuation equaled 3.6 times revenue and 15.3 times EBITDA, with revenue of USD 530.0 million for the last twelve months through September 2025.

Historical operating figures add scale to that valuation. Growth Market Reports cites 2024 revenue of USD 530.1 million, up 12 percent, and revenue of USD 437.6 million in the first nine months of 2025, up 16 percent year over year.

Ownership changed on December 23

The acquisition shifted Integral Ad Science from a public-market company to a Novacap-owned business, making the USD 1.9 billion transaction value the central reference point for the former listed security. The comparison between USD 530.1 million of 2024 revenue and the USD 1.9 billion deal value points to an enterprise value of 3.6 times that historical revenue base.

IAS remains privately owned

Integral Ad Science's October 2, 2026 standards initiative is a business development event rather than a listed-share trading catalyst. The company continues to position its platform across the open web, social media, connected television and audio, while the December 2025 ownership change defines the current corporate structure.
