AtkinsRealis Confirms CANDU(TM) Monark Reactor Power Rating

• AtkinsR\u00e9alis clarified its formal submission to the Canadian Nuclear Safety Commission (CNSC) for the CANDU\u00ae Monark reactor specifies a net electrical output of 925 MW.
• The design is engineered with capability to be uprated to approximately 1,000 MW subject to regulatory approvals and site-specific conditions.
• The decision to license at 925 MW prioritizes replicability, regulatory confidence, execution certainty, and avoidance of first-of-a-kind (FOAK) risks.
• This update corrects information previously appearing on the CNSC website regarding the power rating.

• Expectation vs. Reality: The news aligns with previous strategic guidance provided in February 2026 earnings where nuclear revenue targets were raised to $2.5-$3.0 billion by 2027. It validates the technical feasibility required to meet these targets but does not introduce new revenue streams immediately.
• Risk Mitigation: By confirming a conservative rating (925 MW) over an aggressive one (1,000 MW), management reduces execution risk and regulatory friction, which is positive for long-term project certainty.
• Market Context: The stock has already rallied significantly from $66 in April 2025 to highs near $106 in early 2026. This news supports the narrative but does not appear to be a surprise catalyst capable of driving immediate price appreciation beyond current levels without further commercial milestones (e.g., signed EPC contracts).
• Strategic Alignment: Confirms progress on the nuclear pillar following the March 2026 NVIDIA partnership announcement, linking nuclear power to AI data center demand.

• Company: AtkinsR\u00e9alis Group Inc. is a global engineering services firm with significant exposure to infrastructure, nuclear energy, and defence sectors.
• Flagship Project: CANDU\u00ae Monark Reactor. A small modular reactor (SMR) designed for commercial power generation, currently in the regulatory submission phase with CNSC.
• Development Status: Regulatory clarification on power rating achieved; awaiting final licensing approval.
• Other Key Projects: Sellafield Decommissioning Framework (£4.6bn), Rolls-Royce Submarines Partnership (£400m), Wessex Rail Signalling Upgrade (£98m).
