Rating locked: sign in to viewTeam rating and score are available to subscribers

Focused person-name searches and issuer/regulator follow-up improved the evidence base for OM Holdings’ 14-person management roster. Primary annual reports corroborate roles and selected biographies. The review documents a fatal mine-safety offense convicted against subsidiary OM (Manganese) Ltd, with senior-parent role overlap for Low Ngee Tong and company-secretary disclosure context for Heng Siow Kwee and Julie Wolseley; the court did not find those individuals liable. A related-party subscriber-note interest of Low was disclosed and later redeemed. Remaining individual chronology, qualifications, outcomes, adverse-history coverage and independent corroboration are incomplete.

Current
SafetyDocumented · High materiality

Group-level safety oversight context: fatal Bootu Creek incident and subsidiary conviction

A worker died at the Bootu Creek mine in August 2019. The NT Local Court later recorded that mine operator OM (Manganese) Ltd pleaded guilty to one category 2 offence for failing to ensure safety and exposing workers to risk of death or serious injury, and fined it A$487,500. The court also recorded cooperation, early plea, remorse and remedial steps. Low was OMH executive chairman/CEO in the relevant period, creating group-level role overlap; the judgment identifies the subsidiary as offender and does not find Low personally liable or responsible for the operational failures.

Role overlaps event; causation unproven · Low’s senior parent-company role overlaps the period, but the court judgment establishes no personal culpability or operational involvement by him.

GovernanceDocumented · Medium materiality

Disclosed related-party subscriber notes to wholly owned subsidiary

In November 2022, OMH disclosed that Low and related parties were among subscribers to OMS private bonds used partly to fund a 25% acquisition interest in OM Sarawak/Samalaju. In a June 2026 director notice, Low reported that he personally entered a A$3 million OMS subscriber-note contract at 10% annual interest, and that the notes were fully redeemed as announced on 23 March 2026. The filings disclose the relationship and terms; the reviewed evidence does not establish impropriety.

Individual involvement documented · Low directly entered the subscription contract with a wholly owned subsidiary; repayment/redemption is disclosed. No adverse regulatory or court determination is evidenced in these sources.

This is issuer-attributed career context, not independent causal verification or a performance benchmark.

Individual involvement documented · The issuer attributes the operating-network contribution to Low; no independent causal or shareholder-return analysis was performed.

Contributions and company outcomes

Issuer-reported workforce training MoA

2022-02-11 · issuer reported · medium materiality

OM Sarawak signed a MoA with UNIMAS in February 2022 for a four-week manufacturing-theory course and a six-month workplace module delivered by Sarawak industry professionals. The issuer quoted Lisa Chee, then GM HR/Admin, describing local workforce upskilling as the aim. This supports her attributed HR/program role, not completion, participant outcomes or measured impact.

Attribution: Individual involvement documented. The issuer attributed the program objective and comments to Lisa; no independent outcome data was located in the reviewed sources.

Relevance: Relevant evidence of a human-resources initiative associated with her remit; outcome evidence remains limited.
