Poste Italiane stock (ISIN IT0003796171) closed at EUR 25.61 on the Borsa Italiana on September 23, 2026, down EUR 1.06 or 3.97 percent from the previous close. The move followed Poste Italiane's expanded control of Telecom Italia, with the stake reaching about 67 percent during the extended offer period.

TIM transaction drives the move

Il Sole 24 Ore reported on September 23, 2026, that Poste held 70.5 percent of TIM's share capital on the third day of the extended offer period. The increase changes Poste's profile from a financial-services and postal group into a company carrying a much larger telecommunications exposure.

The Globe and Mail reported on September 22, 2026, that Poste had acquired a controlling interest in Telecom Italia after reaching about 66.6 percent of the share capital. The transaction also gives Poste indirect ownership of TIM Brasil, adding a further operating asset to the enlarged group.

Valuation remains divided

During September 22 trading, the stock stood at EUR 26.27 and fell 1.50 percent, while market capitalization was EUR 39.56 billion. A MarketScreener snapshot cited an average analyst target of EUR 29.49 against a previous close of EUR 26.67, implying 10.58 percent between the reference close and the average target.

In the September 22, 2026 analysis published by Ad hoc News, Evaluation.it assigned Poste a fair value of EUR 26.10 and a hold recommendation. That figure was EUR 0.57 below the September 21 close, while the broader average target was EUR 2.82 higher than the same reference point, showing a split valuation around the TIM deal.
