What believers are saying

  • Australia's AUD 100B annual defence budget by 2033-34 boosts advisory opportunities.
  • AUKUS AUD 50B submarine investment aligns with nuclear engineering capabilities.
  • Investment-grade S&P rating enables acquisitions like Coras and WGA.

What critics are saying

  • Australian regulators block Coras acquisition in 3-6 months over foreign ownership.
  • AECOM undercuts on AUKUS contracts, stripping $500M backlog in 6-12 months.
  • Ontario Power Generation delays Darlington, erasing $2.5B nuclear revenue in 12-24 months.

What makes AtkinsRéalis unique

  • Combines global engineering with Coras' local Australian defence advisory expertise.
  • Acquires WGA adding 800 professionals in transportation, water, and defence infrastructure.
  • Secures record $21.2B backlog from nuclear services and infrastructure projects.
