Alpek and Controladora Alpek successfully conclude merger process

Monterrey, Nuevo Leon, Mexico. December 9, 2025 — Alpek, S.A.B. de C.V. (“Alpek” or the “Company”) today announced the conclusion of the merger process with Controladora Alpek, S.A.B. de C.V. (“Controladora Alpek”). The Shareholders of Controladora Alpek received shares of Alpek, and therefore, effective as of today, they are now Shareholders of Alpek. As a result, Controladora Alpek has ceased to exist and has been delisted from the Mexican Stock Exchange.

Today’s announcement marks the completion of a process that began just over a year ago with the spin-off from Alfa, S.A.B. de C.V., followed by the incorporation and listing of Controladora Alpek on the Mexican Stock Exchange, and, most recently, the merger of Controladora Alpek into Alpek.

“The completion of the merger represents a strategic milestone for Alpek, reinforcing our market position and supporting our commitment to creating long-term value for our Shareholders. Additionally, having a single listed entity with a higher stock float, followed by an expected improvement in share liquidity, will enhance the Company’s probabilities to be included in indices such as the Mexican IPC.” said Jorge Young, CEO of Alpek.
