AtkinsRéalis to Acquire WGA in Major Push into ANZ Infrastructure Market

MONTREAL, QC – April 21, 2026 – Global engineering and nuclear services giant AtkinsRéalis announced today its intention to acquire Wallbridge Gilbert Aztec (WGA), a prominent Australian and New Zealand engineering consultancy. The move marks a significant strategic expansion for the Canadian-based firm, positioning it to capitalize on a massive wave of infrastructure, energy, and defence spending across the region.

The proposed acquisition, structured as a scheme of arrangement under Australian law, will integrate WGA's 800 professionals into AtkinsRéalis's global network. This follows AtkinsRéalis's purchase of Brisbane-based firm ADG in late 2025, collectively boosting its regional headcount to over 1,100 and creating a formidable new player in the competitive ANZ engineering landscape.

A Strategic Play for a Booming Market

The timing of the acquisition is no coincidence. Both Australia and New Zealand are in the midst of historic infrastructure investment cycles, creating a fertile ground for engineering and project management services. Australia's major project pipeline is forecast to peak at over $80 billion in the 2026 financial year, part of a broader $450 billion construction and infrastructure pipeline. This boom is fueled by government commitments to transportation, hospitals, and, most notably, the green energy transition and national defence.

Australia's ambition to generate 82% of its electricity from renewable sources by 2030 is driving record investment, with an estimated $163 billion in public and private projects slated for the next five years. Simultaneously, the nation's defence budget is projected to surpass $100 billion annually in the 2030s, largely driven by the AUKUS security partnership and the need for new infrastructure to support a nuclear-powered submarine program. New Zealand mirrors this trend with its own 30-year National Infrastructure Plan, projecting annual capital investment to double from over $20 billion to more than $40 billion by the 2050s, with a strong focus on utilities and renewables.

"This transaction reflects our continued investment in the AMEA region, in line with our 'Delivering Excellence, Driving Growth' strategy," said Ian L. Edwards, President and Chief Executive Officer of AtkinsRéalis. "Australia is a priority market for us, where we are rapidly building scale and capability."

While the financial terms of the deal were not officially disclosed, industry analysts estimate the acquisition cost to be approximately $261 million. The move is a key part of AtkinsRéalis's 2025-2027 strategic plan, which leverages a reported $3.2 billion in available capital for accretive mergers and acquisitions in high-growth markets.

Combining Global Scale with Local Expertise

The acquisition is built on a strategy of synergy, combining AtkinsRéalis's global resources with WGA's deep-rooted local presence. Founded in 1976, WGA has built a reputation for practical, high-quality solutions delivered by a regionally embedded team. Its portfolio includes landmark projects such as the Adelaide Oval redevelopment, Adelaide's O'Bahn tunnel, and significant contributions to wind farms, solar projects, and marine infrastructure like the Port of Brisbane.

By joining forces, WGA gains access to AtkinsRéalis's international network, advanced digital capabilities, and the capital required to compete for larger and more complex projects. This allows the firm to scale its operations without losing the local touch that has defined its success for over four decades.

"Joining AtkinsRéalis would mark a significant next step for WGA," said Ben Stapleton, Joint Managing Director of WGA. "Becoming part of AtkinsRéalis would enable us to build on these strengths by connecting our team to broader technical expertise, global opportunities and investment, supporting and accelerating the next phase of our growth across Australia and New Zealand. Importantly, we can do this while staying true to what makes WGA unique."

This "global capabilities, local proximity" approach is designed to ensure continuity for WGA's existing clients while providing its employees with expanded career development and technical growth opportunities on a global stage.

Reshaping the Competitive Landscape

The integration of WGA and ADG into AtkinsRéalis is set to significantly alter the competitive dynamics of the Australian and New Zealand engineering consulting markets. The sector, currently characterized by a fragmented landscape with major players like Aurecon, GHD, and Jacobs, will now see a newly strengthened competitor with a comprehensive service offering.

With a combined force of over 1,100 professionals, the expanded AtkinsRéalis will be better positioned to challenge established firms for major public and private sector contracts. The firm's enhanced capabilities will span the full project lifecycle, from advisory and design to project management and operations, across key sectors including transportation, water, power, defence, and resources. This increased scale and depth will be critical in bidding for the multi-billion-dollar infrastructure programs that are defining the region's economic future. The move signals a clear intent to move beyond niche roles and become a leading, full-service provider in the ANZ market.

The Path to Integration and Approval

Before the vision of a combined entity can be realized, the transaction must navigate a series of regulatory and shareholder hurdles. As a scheme of arrangement, the deal requires approval from WGA's shareholders, the Australian courts, and key regulatory bodies.

Given the foreign ownership and the strategic importance of the sectors involved—particularly defence and critical infrastructure—the deal will face scrutiny from Australia's Foreign Investment Review Board (FIRB). The FIRB process, which includes a national security test, can be rigorous and may extend the transaction timeline. The Australian Competition and Consumer Commission (ACCC) will also likely review the merger for any potential impacts on market competition.

Beyond the regulatory process lies the complex challenge of cultural integration. WGA's identity is deeply tied to its employee-owned model and its strong regional culture, which fosters long-term local relationships. Successfully merging this ethos with the structure of a large, publicly-traded global corporation will be critical to retaining the key talent and client loyalty that make WGA an attractive asset. The success of the acquisition will ultimately depend not just on combining balance sheets and project portfolios, but on effectively blending two distinct corporate cultures to create a unified and more powerful force in the regional market.
