The company declared a 2.0c fully franked final dividend, bringing FY2026 dividends to 6.0c/share. Chairman Nathan Mitchell described the result as among the strongest in the company’s history. The company statement does not quantify individual executive contributions.

Relevance: Operating and financial execution is relevant to executive suitability; the outcome provides a measured company benchmark.

Quarter ended 30 September 2026 · issuer reported · medium materiality

Relevance: The distinction between recurring performance and insurance receipts supports an assessment of operating delivery.

Industrial safety

Serious hand injury and rig suspension

FY2023 Q2 · issuer reported · medium materiality

The company said a worker sustained a serious hand injury in the December 2022 quarter, and five rigs were suspended for about a month during the associated investigation. It expected a full recovery. The underlying investigation and final findings were not found.

Attribution: Role overlaps event; causation unproven. Elf was CEO during the period; the source establishes no individual fault or finding against him.

Relevance: Operational safety and the response to a serious injury are material to drilling leadership.

Evidence gaps

• Independent verification of qualifications and complete prior-employer tenure was not obtained.

• The search is limited open-web screening; court, regulator, sanctions and professional records were not exhaustively checked.

• The final findings and worker recovery after the December 2022 hand injury were not obtained.
