Interpublic Group stock (ISIN US4606901001) last stood at USD 24.57 on the NYSE on November 26, 2025 at 4:00 p.m. ET, down 1.96 percent from the prior close of USD 25.06. The decisive event was the completion of Omnicom's acquisition, which ended IPG's independent listing.

NYSE listing ended in merger

According to StockTitan, the November 26, 2025 filing states that Interpublic became a direct wholly owned subsidiary of Omnicom. The filing also says IPG common stock would cease trading on the NYSE, be delisted and be deregistered.

The exchange ratio defines the value handed to former shareholders: each IPG share converted into 0.344 Omnicom shares, plus cash in lieu of fractional shares. That is a structural comparison rather than a fresh trading signal, because the IPG security itself no longer represents a separately traded equity claim.

Final quote shows the transition point

Investing.com identifies IPG as a NYSE-listed USD security with ISIN US4606901001 and displays the final session at USD 24.57. Its quoted session data show a day range of USD 24.47 to USD 25.32 and a 52-week range of USD 22.51 to USD 28.42.

The merger also changed the balance-sheet and reporting context. The filing says approximately USD 9.5 million of letters of credit moved to Omnicom's credit facilities, while IPG's revolving credit agreement ended with no outstanding borrowings. The same filing describes the conversion of outstanding IPG stock options into Omnicom options.

Corporate identity now sits with Omnicom

Interpublic's supplied corporate URL now presents Omnicom as a marketing and sales company with advertising, branding, media, public relations and precision-marketing capabilities. The Interpublic page also highlights Omnicom's Omni platform and its September 21, 2026 corporate update.

IPG stock remains a historical quote

For investors reviewing historical records, the relevant reference is the November 26, 2025 NYSE quote of USD 24.57, not a new independently traded IPG session. The ownership exchange, delisting and website transition together mark the change from Interpublic as a listed company to Interpublic as part of Omnicom.
