Interpublic Group of Companies, Inc. (ISIN US4606901001) ended between an intraday low of USD 24.470 and a high of USD 25.320, with volume at 52,499,952 shares. The close sat 1.89 percent below the prior session and 2.78 percent below the days high, while the broader US market also traded lower.
As StockTitan reported, IPG said its stock will cease trading on the NYSE and will be delisted and deregistered after the merger closes. WhendoMarketsOpen lists September 15, 2026 as a normal US trading day, and the next event tied to the deal is the corporate-action transition rather than a new trading session catalyst.
Today after the open
IPG shares are in the final corporate-action phase after the merger, so the main item today is the market's handling of the delisting process and any related notices from the company or exchange operator.
