Business failures and setbacks

Calidus administration and impaired receivable

June–August 2024 · issuer reported · medium materiality

Macmahon reported that client Calidus entered administration in June 2024 and its Warrawoona operations entered care and maintenance. Macmahon fully impaired an A$31.8m receivable at FY2024; management then expected a possible route to recovery through the receivers’ sale or recapitalisation process. Final recoveries are not established here.

Attribution: Role overlaps event; causation unproven. A senior executive held the stated position; neither the client failure nor the impairment establishes personal responsibility.

Relevance: Material counterparty and credit-risk outcome during the executive team’s tenure.

Industrial safety

Fosterville fatality and ongoing investigation

December 2025–October 2026 · documented · high materiality

A Macmahon employee died in a 5 December 2025 underground event at Fosterville. The chair said at the 23 October 2026 AGM that investigations were ongoing. The issuer reported FY2026 TRIFR 1.98 versus 2.99 in FY2025; this metric does not offset the fatality.

Attribution: Role overlaps event; causation unproven. The person held a group or underground leadership role during the event; sources do not establish individual causal responsibility, specific site actions, or a final investigation outcome.

Relevance: Material to oversight of workplace safety.

Governance and interests

FIFO harassment inquiry and company response

2021 and subsequent company-reported programs · documented · high materiality

In 2021 the WA parliamentary inquiry heard company evidence about harassment reports and company procedures. Finnegan acknowledged prevention and screening had failed female workers; the company reported changes to screening, reporting and roster practices. Its written response identified HR investigations reporting to people GM Nicola Hamilton. This concerns organisational controls; it is not a personal harassment finding.

Attribution: Individual involvement documented. Finnegan personally gave the cited testimony; Hamilton appeared and was responsible for the reported HR reporting line. No source identifies either as a perpetrator.

Relevance: Relevant to workforce governance and company prevention controls.

Evidence gaps

• Independent verification of education, credential status, full prior-employer tenures and individual outcomes is incomplete.

• Focused public-source screening is not a comprehensive court, regulatory, criminal, sanctions or credential check; some historical employer records and local-language sources were not reviewed.

• The completed Fosterville investigation, cause and individual responsibilities were unavailable through the cutoff.

• Final recoveries on the Calidus receivable and individual decision-making are not established.
