BHP is trading 3.2% down at $80.64 in pre-market action after disclosing significant cost overruns and a multi-billion dollar impairment charge at its Jansen potash project in Canada.

  • Capital spending for Jansen Stage 1 has risen sharply, leading to an expected post-tax impairment of $2.0–$2.3 billion in fiscal 2026.
  • The news has pressured investor sentiment despite the company's stated long-term commitment to the project.
  • The impairment reflects the immediate financial impact of the project's increased budget and revised valuation.
