LYB signs SPA to divest four European O&P sites; H1 2026 close targeted.

LyondellBasell has executed an SPA with AEQ Amethyst B.V. to sell subsidiaries holding its European olefins and polyolefins operations in the UK, Spain, Germany, and France. The process advanced after the French consultation completed on October 15, 2025 and the put option was exercised on October 23, 2025.

Closing is conditioned on regulatory clearances, further employee and works council consultations, and completion of carve‑outs and transfers. These steps can influence timing and final structure, but they are described as customary for transactions of this type.

The company indicates an expected close in the first half of 2026. Subsequent filings may provide additional details about the closing progress and any remaining consultations or approvals.

(the “Purchaser”) entered into a Put Option Letter Agreement (the “Agreement”) for the acquisition by the Purchaser of all of the issued and outstanding equity interests in the subsidiaries of LYB that hold (or will hold) the assets and liabilities of its olefins and polyolefins businesses at Carrington (UK), Tarragona (Spain), Münchsmünster (Germany), and Berre l’Etang (France) (collectively, the “Target Group”), including central supporting functions (such acquisition, the “Transaction”).

Under the Agreement, as reported on the Current Report on Form 8-K (the “Prior Form 8-K”) filed by LYB on that same date, the Purchaser made an irrevocable commitment to enter into the Transaction subject to the terms and conditions of a sale and purchase agreement attached thereto (the “SPA” and such commitment, the “Put Option”). The Seller’s right to exercise the Put Option was subject to the terms and conditions of the Agreement, including the completion of required employee notification and works council consultation processes as described in the Prior Form 8-K. The French consultation process was completed on October 15, 2025, and on October 23, 2025, the Seller exercised the Put Option.

The SPA contains customary representations, warranties and covenants by the parties, including post-closing covenants related to employee and other matters.

The closing of the Transaction is subject to customary closing conditions, including satisfaction of regulatory conditions, completion of additional required employee representative and works council consultation processes, and completion of the carve-out and transfer of the relevant assets and liabilities to the Target Group entities. The Transaction is expected to close during the first half of 2026.

The foregoing descriptions of the Agreement and SPA do not purport to be complete and are qualified in their entirety by reference to the full text of the Agreement (which was previously filed as Exhibit 10.1 to the Prior Form 8-K) and the SPA, which is attached to this Current Report on Form 8-K as Exhibit 10.1, each of which is incorporated herein by reference.
