Aecon Stock Jumps Over 5% on C$1.75 Billion Share of Pickering Nuclear Contracts

Shares of Aecon Group Inc. (TSX: ARE) surged more than 5% on Tuesday after the company disclosed its joint ventures have won contracts totaling C$3 billion for the refurbishment of Ontario's Pickering Nuclear Generating Station.

In a disclosure made just before the market closed on Monday, the engineering and construction firm announced its share of the award is C$1.75 billion, which will be added to its Construction segment backlog in the third quarter of 2026.

Landmark Nuclear Contracts

The awards from Ontario Power Generation (OPG) cover two critical scopes of work and represent one of the largest nuclear infrastructure projects in Canadian history. The contracts include:

• A C$1.7 billion project for the Retube, Feeder and Boiler Replacement of Unit 5, awarded to a joint venture between Aecon and AtkinsRéalis.
• A C$1.3 billion project for the Turbine Generator Replacement, awarded to a consortium of Aecon and Siemens Energy.

The refurbishment is intended to extend the operational life of four of the station's CANDU reactors by up to 38 years.

Market Impact and Financial Outlook

The news sent Aecon's stock up 5.4% to C$53.55 in Tuesday's trading. For investors, the massive contract win significantly enhances Aecon's revenue visibility and reinforces its growth prospects.

The award builds on an already strong financial position. As of March 31, 2026, Aecon reported a record backlog of $10.9 billion. The company's second-quarter 2026 results also showed a 25% year-over-year revenue increase to $1.63 billion and a doubling of Adjusted EBITDA to $82.4 million.

Broader Context

The contract announcement overshadowed broader market dynamics, including mixed North American indices and rising Canadian bond yields, which can create headwinds for capital-intensive sectors like construction. The news could also generate positive sentiment for sector peers, including project partner AtkinsRéalis.

Coinciding with the stock's move, Tuesday also marked the ex-dividend date for Aecon's quarterly cash dividend of C$0.1925 per share, payable on October 2, 2026.
