Business failures and setbacks

Emmerson Khemisset permit refusal and arbitration

2024–August 2026 · documented · high materiality

Emmerson, where Locke is chairman, reported the project environmental approval was refused in October 2024 and recorded a US$21.1 million impairment for 2024. Its subsidiaries seek US$1.215 billion in arbitration against Morocco. In July 2026 the tribunal refused a separate preliminary phase for jurisdiction; this was procedural, not a merits decision. An August report records a 2028 hearing timetable.

Attribution: Role overlaps event; causation unproven. Locke is chair; the sources do not establish personal culpability or determine the parties’ disputed claims.

Relevance: Shows a material development and permitting setback at another enterprise associated with the CEO.

Governance and interests

Concurrent Emmerson arbitration incentive

May–June 2026 · issuer reported · medium materiality

Emmerson’s 2025 annual results disclosed a plan allocating 6% of any arbitration compensation to a pool, of which Locke was allocated 22%, conditional on a recovery.

Attribution: Individual involvement documented. The contingent award is disclosed; it is not itself evidence of misconduct.

Relevance: Shows a concurrent financial interest and another demand on management attention.
