Poste Italiane stock falls as improved TIM offer and market selloff weigh

Poste Italiane stock (ISIN IT0003796171) declined 2.77% to EUR 25.66 on Borsa Italiana on September 9, 2026, underperforming a weak Milan market as investors digested changes to its takeover offer for Telecom Italia (TIM) and booked profits after recent gains.

Offer for TIM reshaped and acceptance threshold waived

According to Il Foglio on September 9, 2026, Poste Italiane has increased the cash component of its public offer for TIM and, crucially, decided to waive the previous minimum acceptance threshold of 66.67 percent, allowing the bid to proceed even if a lower proportion of shares is tendered.

As AITRADING67 reports, Poste Italiane has also reopened the offer window for TIM shares from September 21 to September 25, 2026, giving shareholders a new time frame to decide on participation.

In the view of many market observers, the waiver of the acceptance threshold increases the probability that Poste Italiane will end up owning a significant stake in TIM, but it also raises questions about integration risks, capital allocation and future returns; those concerns were visible in the share price reaction on September 9, 2026, with Poste Italiane down 2.77 percent while TIM itself moved lower after the prior-day rally.

Share price moves and Milan market context

Data from Borsa Italiana show that Poste Italiane shares last traded at EUR 25.66 on September 9, 2026, down from an opening price of EUR 26.19, with an intraday high of EUR 26.37 and an intraday low at the closing level of EUR 25.66 on the same session.

According to Corriere.it on September 9, 2026, European equities closed in negative territory ahead of the next European Central Bank meeting, and Poste Italiane was among the more heavily sold Italian names, recording a decline of 2.77 percent compared with a drop of around 0.58 percent for the broader Milan index.

As BlastingNews notes in its market wrap for September 9, 2026, Poste Italiane shares fell 2.77 percent in the session after prior gains and in the wake of the incremental EUR 0.30 per share cash sweetener offered in the TIM bid, suggesting that some investors used the news as an opportunity to lock in profits.

Recent performance, offer implications and investor perspective

The contrasting moves in recent days underline how sensitive Poste Italiane stock is to developments around the TIM transaction: AITRADING67 reports that in a prior session Poste shares closed 0.53 percent higher, while Corriere.it and other outlets highlight the subsequent 2.77 percent pullback once the broader market turned lower and investors weighed the more aggressive offer terms.

For shareholders, the key quantitative comparison is between the improved cash offer for TIM and the underlying profitability and capital strength of Poste Italiane: increasing the cash component by EUR 0.30 per share in the TIM bid, as mentioned by Italian financial media, raises the total consideration and therefore the cost of the deal, which in turn can impact leverage and future dividend capacity compared with a scenario without the offer.

From a strategic perspective, the extended offer window from September 21 to September 25, 2026 and the removal of the 66.67 percent minimum acceptance condition, as described by Il Foglio and AITRADING67, make it more likely that the transaction will close in some form, which may support long-term growth ambitions but also keeps integration risks and regulatory scrutiny firmly in focus for the near term.

Poste Italiane stock price as of the latest session
