Poste Italiane stock (ISIN IT0003796171) is trading against the backdrop of a major strategic shift, after the Italian group moved to secure around 66.6% of Telecom Italia in a public offer valued at approximately EUR 13 billion as of September 18, 2026, according to Forbes Brasil.

Telecom Italia offer reshapes Poste Italiane’s profile

As Poste Italiane reported in a corporate communication dated September 18, 2026, the company concluded the initial acceptance period of its offer on ordinary shares of Telecom Italia, reaching 66.627% of Telecom Italia’s share capital at the end of that phase.

According to the same communication by Poste Italiane, the share capital has been increased through the issuance of new Poste Italiane shares serving the public and exchange offer on Telecom Italia, under a delegation granted by an extraordinary shareholders’ meeting on June 18, 2026, which allowed for a maximum capital increase of EUR 371,986,879 with up to 371,986,879 new ordinary shares.

Capital structure and indirect control of TIM Brasil

The company’s bylaws document dated September 18, 2026 shows that Poste Italiane’s share capital stands at EUR 1,522,713,998.00, divided into 1,522,713,998 ordinary shares with no nominal value, reflecting the current capital structure after the execution of the capital increase related to the offer for Telecom Italia, as stated in the official bylaws filed on that date by Emarketstorage.

As Valor Economico reported on September 18, 2026, Poste Italiane’s move to secure control of Telecom Italia means the Italian postal and financial group becomes the indirect controlling shareholder of TIM Brasil, since Telecom Italia directly controls the Brazilian telecom operator.

Offer valuation and acceptance period dynamics

The Brazilian coverage by Forbes Brasil values the offer at about EUR 13 billion for the 66.6% stake in Telecom Italia, highlighting the scale of the transaction compared with Poste Italiane’s existing roughly 20% participation in Telecom Italia before the offer.

The same report from Valor Economico notes that the acceptance period for the offer is scheduled to be reopened from September 21, 2026 to September 25, 2026, allowing additional Telecom Italia shareholders to tender their shares and potentially increasing Poste Italiane’s stake further.

Stock price and recent trading range

On Euronext Milan, where Poste Italiane stock is primarily listed under ISIN IT0003796171, the last recorded trade on June 19, 2026 was at EUR 28.98 at 5:35 p.m. local time, according to the Euronext quote overview for the security as of that date.

A dividend-related trading snapshot on Borsa Italiana shows Poste Italiane shares quoted at EUR 26.06 with a daily gain of 1.92% at the close on September 11, 2026, indicating that the stock was trading noticeably below the June 19, 2026 level of EUR 28.98 but up compared with immediately preceding sessions around that mid-September date.

Investor takeaway on strategy and risk

For investors, the key quantitative comparison is that the EUR 13 billion valuation for the 66.6% stake in Telecom Italia implies a significant capital commitment relative to Poste Italiane’s existing share capital of EUR 1,522,713,998.00, underscoring the strategic importance of telecom assets alongside the group’s postal, financial and insurance activities.

At the same time, the reopening of the offer’s acceptance period between September 21 and September 25, 2026, as highlighted by Valor Economico, introduces additional execution risk and potential variability in the final stake and cost, factors that investors in Poste Italiane stock will be watching closely.

Poste Italiane stock and market perspective
