Interpublic Group stock leaves NYSE after Omnicom merger

Interpublic Group stock became a former standalone NYSE security after the company merged with Omnicom on November 26, 2025. Each IPG share converted into 0.344 Omnicom shares, making the exchange ratio the key figure for former shareholders on September 24, 2026.
IPG leaves the public market
According to StockTitan, an 8-K dated November 26, 2025 said IPG common stock would cease trading on the NYSE, be delisted and be deregistered. The filing also described IPG as a direct wholly owned subsidiary of Omnicom Group.
The transaction changed the security from an independently traded advertising holding company into an operating unit inside a larger group. For former IPG holders, the 0.344 share conversion matters more than a standalone IPG earnings multiple because the economic exposure moved to Omnicom stock.
Debt exchange adds a second figure
The same filing reported that Omnicom exchanged existing IPG notes with a principal amount of USD 2.95 billion for new Omnicom notes and cash on December 2, 2025. IPG retained USD 185.0 million of outstanding notes after that transaction.
The balance sheet transition also included the transfer of USD 9.5 million of letters of credit to Omnicom credit facilities. These figures show that the merger affected debt obligations as well as the equity listing, giving investors a clearer measure of the integration's financial mechanics.
Last standalone quote
The last quoted IPG price in the available market snapshot was USD 24.57 on November 26, 2025, down 1.96 percent from the prior close of USD 25.06. That historical move is separate from the current corporate status: IPG no longer provides an independent public-market price after the merger.
