Poste Italiane stock (ISIN IT0003796171) is drawing investor attention after the company confirmed the final results of its voluntary tender and exchange offer for Telecom Italia on September 15, 2026, securing a controlling stake of about 66.6 percent in the telecom group according to Poste Italiane.

Telecom Italia offer gives Poste Italiane control

As Poste Italiane reported on September 15, 2026, the company closed the first acceptance period of its voluntary public tender and exchange offer for all Telecom Italia ordinary shares and reached a stake of roughly 66.6 percent of Telecom Italia's share capital, crossing a key control threshold.

According to VermoegensZentrum on September 16, 2026, shareholders tendered 993,596,322 Telecom Italia shares, equal to about 46.52 percent of the telecom company's share capital, which, together with Poste Italiane's pre-existing stake, lifted its holding to around 66.63 percent.

The same report from VermoegensZentrum notes that settlement for shares tendered in the first period is set for September 18, 2026, with consideration consisting of 0.218 newly issued Poste Italiane shares plus EUR 1.97 in cash per Telecom Italia share, and Poste Italiane is due to issue 216,603,998 new shares to deliver the equity component of the offer.

Offer timetable and strategic implications for investors

As Finimize highlighted on September 16, 2026, crossing the 66.627 percent holding marks a key control line for Poste Italiane in Telecom Italia, giving the state-backed group effective control over the telecom operator and strengthening its position to drive integration between postal, financial and telecom services.

The tender offer process is not yet complete: according to VermoegensZentrum, an additional acceptance period will reopen between September 21 and September 25, 2026, giving remaining Telecom Italia shareholders a second window to tender their shares, with payment for that second tranche scheduled for October 2, 2026.

For investors in Poste Italiane stock, the combination of a 66.6 percent stake and the reopened acceptance period means the group can still increase its Telecom Italia holding beyond the current level, potentially adding to earnings and cash flow in the medium term while also increasing integration and execution risks related to telecom operations.

Stock performance and valuation context

On Borsa Italiana in Milan, Poste Italiane stock recently traded in the mid range of its 52-week band; as of mid September 2026, the shares are quoted on the primary listing in EUR, with the latest closing price, prior close and daily percent change indicating that the stock is currently positioned in the upper half of its 52-week low to high interval.

Based on recent market data as of September 15, 2026, Poste Italiane stock on Borsa Italiana closed near the midpoint between its 52-week low and 52-week high, while market capitalization in EUR terms reflects the enlarged share count resulting from the planned issuance of 216,603,998 new shares tied to the Telecom Italia offer.

For comparison, the offer terms effectively value each Telecom Italia share at a mix of Poste Italiane equity plus EUR 1.97 in cash per share according to VermoegensZentrum, and investors can use this ratio and the current Poste Italiane share price to gauge the implied valuation uplift relative to recent Telecom Italia trading levels.

Risks and next milestones

The main near-term milestone for Poste Italiane stock is the settlement of the first acceptance period on September 18, 2026 and the reopening of the offer window from September 21 to September 25, 2026, which will determine the final stake in Telecom Italia and the total number of new Poste Italiane shares to be issued as part of the deal according to VermoegensZentrum.

From a risk perspective, integration of a majority-controlled Telecom Italia will expose Poste Italiane to the capital intensity, competition and regulatory environment of the Italian telecom sector, which could weigh on margins and require further investment, even as the expanded group seeks synergies across postal, financial and telecom services as discussed by Quotidiano on September 16, 2026.

Investors in Poste Italiane stock therefore need to weigh the potential for higher long-term earnings and diversification from controlling Telecom Italia against the near-term dilution from new share issuance and the operational challenges of managing a large telecom operator under a state-backed group structure.
