**EXHIBIT 99.1**

**Stantec joint venture to deliver Greater Western Water's infrastructure program**

EDMONTON, Alberta and MELBOURNE, Australia, May 26, 2026 (GLOBE NEWSWIRE) -- **TSX, NYSE:STN**

Stantec, a global leader in sustainable design and engineering, in a joint venture with Jacobs, a science-based consulting and advisory leader, has been selected to support Greater Western Water's (GWW) five-year Infrastructure Planning and Delivery Program—an ambitious, future-focused initiative shaping how water infrastructure is planned, designed, and delivered across the rapidly growing western region of Melbourne, Australia.

Over the course of the five-year appointment, the integrated team will work alongside GWW to deliver critical water and sewer infrastructure that supports sustainable growth, strengthens resilience, and enhances outcomes for customers and communities, today and for generations to come.

Western Melbourne's population is forecast to more than double by 2050, placing increasing pressure on the existing infrastructure in some areas. The infrastructure program responds to this growth with a more integrated approach that brings collaboration, efficiency, and innovation to the forefront while delivering reliable water and wastewater services for a growing population.

The joint venture will provide a comprehensive suite of engineering and advisory services to help meet the region's expanding needs and address the escalating challenges posed by climate change and extreme weather. The services will include option assessments, functional and detailed designs for water and wastewater systems, treatment plants, and dams, as well as groundwater and surface water assessments, discharge quality analysis, and construction support. The team will also lead investigations of contaminated land and help establish engineering standards that support safe, resilient delivery.

**Partnering for a resilient future**

"This program reflects our team's deep expertise delivering water and sewer infrastructure that strengthen essential services for the communities we serve," said Ashok Sukumaran, Australia country leader at Stantec. "Our engineering solutions will help protect Melbourne's vital water resources by delivering sustainable services in the face of a changing climate and population growth. We look forward to continuing our longstanding relationship with Greater Western Water."

"Rapid population growth across Melbourne's western region requires water infrastructure that can scale efficiently and reliably," said Sinead Giblin, executive vice president at Jacobs. "By working closely with Greater Western Water and the program teams, we're bringing together integrated planning, technical expertise, and innovation to support sustainable, resilient water networks and treatment systems that serve communities now and into the future."

"This partnership plays an important role in shaping how we plan and design infrastructure, bringing strong expertise to support projects across our service area," said Ian Burton, Greater Western Water's general manager of asset planning and delivery. "We look forward to working together to ensure we continue to meet the needs of our customers and communities with water and sewerage services that are safe, consistent and resilient."

Beyond infrastructure delivery, the infrastructure program will also facilitate social procurement initiatives, engagement with Indigenous-owned businesses, and the creation of employment pathways for local job seekers and graduates.

**Building long-term partnerships for water resilience**

This appointment builds on Stantec's growing global portfolio of major water programs. The firm is currently an engineering partner for Urban Utilities' Next Generation 4 Delivery (NG4D) program in Southeast Queensland, a multibillion-dollar initiative advancing a resilient and sustainable water future. Stantec was also recently named a primary designer for Scottish Water Enterprise, a transformative, multibillion-pound program improving water resilience across Scotland.
