Poste Italiane stock (IT0003796171) traded at EUR 16.385 on March 22, 2025, after a 0.3 percent decline, while the share touched an annual high of EUR 16.62 on March 19, 2025. The latest trigger is Poste Italiane's bid for TIM, which lifted acceptances to 58.23 percent and total control to 66.63 percent, according to MarketScreener on September 14, 2026.

TIM bid sets the pace

According to MarketScreener, Poste Italiane increased the cash part of its offer to EUR 1.97 per share plus 0.218 Poste shares, and the goal is now to reach 90 percent for a squeeze-out and delisting. The same report says the offer will reopen from September 21 to 25, 2026, which keeps the story centered on execution rather than valuation alone.

The figure that matters most for investors is the scale of the transaction: 58.23 percent acceptances at the close of the offer, 66.63 percent control including Poste's existing stake, and a target of 90 percent. That combination gives the market a concrete reference point for the next step in TIM, while the share itself stays anchored in the EUR 16 range on the available price snapshot.

Operating target stays large

MarketScreener also reports that Poste is aiming to build a group with EUR 5 billion in operating profit and EUR 700 million in annual synergies. Those figures frame the deal as more than a stake increase, because they indicate the operating scale management is pursuing around TIM.

For shareholders, the key comparison is between the current 66.63 percent control and the 90 percent threshold that would enable a squeeze-out. If the offer reaches that level, the delisting path becomes the central corporate event, and the reopening window from September 21 to 25, 2026 becomes the next visible checkpoint.
