Pirelli & C. S.p.A. stock traded at EUR 6.615 on the Borsa Italiana on September 23, 2026, up 0.61 percent from the previous close. The immediate corporate catalyst is a shareholder increase to 29.9 percent, while a planned EUR 1 billion US expansion adds a long-term operating dimension.

Ownership reaches 29.9 percent

According to Reuters on September 23, 2026, Marco Tronchetti Provera & C. increased its overall stake in Pirelli to 29.9 percent through its control chain. Camfin Alternative Assets bought 3.34 percent of Pirelli's capital from a primary banking institution.

The comparison is material: the latest transaction lifted the holding by 3.34 percentage points to the maximum aggregate participation previously authorized. For investors, the ownership structure is therefore as important as the daily price move, because the transaction increases the position of the group linked to Pirelli's historic controlling shareholder.

US expansion adds 6 million tires

According to Investing.com on September 22, 2026, Pirelli's board approved a EUR 1 billion investment plan to expand its Rome, Georgia manufacturing facility. Construction is scheduled to begin in 2027 and finish in 2033.

The project is planned in two stages. Robotized production using Pirelli's MIRS technology is expected to reach 3 million tires annually from 2028, followed by a second facility that adds another 3 million tires. Total annual capacity would therefore rise by approximately 6 million car tires, including products using Cyber Tyre technology.

The same Investing.com report states that the investment will not change Pirelli's 2026 targets. The capex-to-revenue ratio for 2027 through 2033 is expected to remain consistent with previous periods, which limits the immediate effect on the company's current-year outlook while preserving the strategic capacity increase.

Stock trades at EUR 6.615

Pirelli stock stood at EUR 6.615 on the Borsa Italiana on September 23, 2026, with a daily gain of 0.61 percent. The price reaction was measured even as the ownership transaction and US manufacturing plan supplied two distinct signals: greater shareholder concentration and a multi-year expansion of high-value tire capacity.
