Seven & I Holdings shares climbed the most in more than a year on news that it is in talks to invest several hundred billion yen to acquire a stake in Poland¡¯s No. 1 convenience-store operator Zabka Group.

The transaction, if completed, would allow the 7-Eleven operator to accelerate expansion in Europe where growth has lagged behind its main markets in the U.S. and Japan. The company confirmed the negotiations with a large convenience-store operator in Poland, adding that nothing had been decided.

Seven & I¡¯s stock rose as much as 5% in early trading Friday, the most since April 2025 on an intraday basis. Zabka jumped 16% to a record high on Thursday, valuing the company at 32.7 billion zloty ($8.7 billion).
