WSP to acquire Australia-based Calibre

The Argyle diamond mine in Western Australia, a Calibre project involving dismantling operational infrastructure, reshaping land and revegetation to enable the reestablishment of a natural ecosystem.

Proposed acquisition of engineering services provider will strengthen WSP’s sustainability capability in the mining sector.

WSP has announced that it has entered into an agreement to acquire Calibre Professional Services, strengthening its position as a leading firm providing sustainability services across the full mining asset life cycle.

Building on the acquisition of Golder in 2021 and in alignment with the company’s 2022-2024 strategic action plan objectives, the transaction will enable WSP to further develop its leadership position in Australia as well as support major mining clients who are currently on a path to decarbonise their operations and infrastructure.

Calibre is a leading engineering services provider across the full asset life cycle, focused on rail, infrastructure, rehabilitation and renewable projects supporting blue-chip mining clients. With a workforce of approximately 800 professionals, Calibre has offices in Perth, Sydney, Melbourne and Brisbane.

The addition of Calibre and its mining advisory and consulting expertise will position WSP to seize significant opportunities related to mine closure and rehabilitation as well as water management. The combined platform will represent over 6,000 professionals across Australia, including over 1,000 experts in the resource sector and significantly increase WSP’s presence in the Pilbara region and Western Australia.

Alexandre L’Heureux, WSP’s president and CEO, said: “This transaction will further position WSP to play a leading role in assisting with the green transition of the mining industry in Australia and globally. Our combined business will further increase our technical capabilities and provide opportunities to serve as the partner of choice for mining companies with strong ESG commitments.”

“Together with Calibre, our ability to deliver services to help accelerate the energy transition and the decarbonization of the mining sector will be vastly enhanced,” said Guy Templeton, WSP’s Asia Pacific president and CEO.

Adrian Chapman, Calibre’s executive general manager, said: “Joining WSP will create a leading and highly technically capable firm, adding value to major projects beyond mine sites and enabling us to bring WSP’s key ESG services to a wider client base.”

The transaction is expected to close in the second quarter of 2023 and is subject to customary closing conditions.
