WSP Withdraws Offer to Acquire Arcadis

MONTREAL, Sept. 22, 2026 /CourierPR/ -- WSP Global Inc., one of the world’s leading engineering, science and infrastructure solutions firms, has announced that it will not pursue a public offer for all of the issued and outstanding shares of Arcadis N.V. ("Arcadis"). The decision comes after careful consideration of the strategic and industrial merits of a potential combination between the two organizations.

WSP, which operates in over 50 countries and employs approximately 83,000 professionals known as Visioneers, remains convinced that a combination of WSP and Arcadis would offer a compelling strategic rationale and generate substantial benefits for all stakeholders, including shareholders, clients, and employees of Arcadis and WSP.

However, WSP was unable to engage with Arcadis regarding the terms of a potential transaction. The company continues to believe that the value creation opportunity underlying a combination of Arcadis and WSP can only be realized through a negotiated transaction supported by the Arcadis boards. Without such engagement, WSP is not positioned to further advance a transaction.
