Contributions and company outcomes

ANTAM reported stronger 9M26 financial results during his presidency

1 January–30 September 2026 · issuer reported · medium materiality

ANTAM reported 9M26 net profit of Rp9.66 trillion, up 46% year over year, EBITDA of Rp13.48 trillion and sales of Rp88.48 trillion. His President Director tenure began in December 2025, so the nine-month period partly overlaps his tenure. The release is issuer-reported and does not isolate personal contribution or separate commodity, mix and execution effects.

Attribution: Role overlaps event; causation unproven. The role overlaps only part of the reporting period; no personal causation is established.

Relevance: Relevant current performance context, but not evidence of sole or attributable CEO delivery.

Litigation and enforcement

Appeal conviction for unlawful deprivation of liberty in the Tim Mawar case

1997–2000 proceedings; final appeal 24 October 2000 · documented · high materiality

A 1999 military court judgment identifies Untung Budi Harto as Defendant V and Unit I commander and describes his participation in group operations involving abduction and detention of nine named activists. Hukumonline’s later account says the appeal court convicted 11 defendants, changed Untung’s sentence to 2 years 10 months and removed the dismissal sanction; it reports the judgment was final and the sentence served. ICTJ/KontraS distinguishes those nine detained activists from 13 activists who remained missing; the reviewed evidence does not establish Untung’s role in the missing-person cases.

Attribution: Individual involvement documented. Court records connect him to the unlawful detention operation; no broader role in disappearance of the 13 still-missing activists is established by the reviewed sources.

Relevance: Material integrity and governance history for a current state-controlled miner CEO; historical conviction is documented, with scope carefully bounded.

Suitability for the current role

Military and public-sector leadership precedes ANTAM presidency

1988–15 December 2025 · analyst inference · medium materiality

ANTAM reports that Untung graduated from the Military Academy in 1988 and held senior military and government roles, including Commander of Kodam Jaya (2022–23), President Commissioner of Transjakarta (2023–25) and roles at BNPT and Basarnas. ANTAM says he became President Director on 15 December 2025. The biography supports leadership experience but does not document mining operating or capital-allocation results before ANTAM.

Attribution: Responsibility not applicable. The career chronology is company-reported; individual performance in the prior public roles was not independently assessed.

Relevance: Relevant leadership breadth, with limited direct mining track record established by the sources reviewed.

Evidence gaps

• His mining-industry tenure before appointment and independently measured outcomes in prior military/government roles were not established.

• The historical court record concerns nine activists detained; reviewed sources do not establish his involvement in the 13 activists who remained missing.

• No exhaustive legal, sanctions, professional-discipline or referee check was performed.

ANTAM reported 9M26 profit of Rp9.66 trillion (+46%) and EBITDA of Rp13.48 trillion (+45%). Dewa’s revised board appointment was recorded at the June 2026 GMS, so only part of the period overlaps the role; the issuer release does not attribute the results to him.

Attribution: Role overlaps event; causation unproven. Only the post-appointment portion overlaps his current directorship; personal causation is not established.

Relevance: Useful current company context, not a personal performance measure.

Litigation and enforcement

KPK summoned him as a witness in the Antam/Loco Montrado anode investigation

2017 matter; witness summons 9 June 2023; later case outcomes through 28 April 2026 · documented · medium materiality

RMOL reported that KPK summoned I Dewa Wirantaya as a witness on 9 June 2023 in an investigation into alleged anode-processing corruption involving ANTAM and Loco Montrado, concerning suspect Siman Bahar. A separate ANTAM manager, Dody Martimbang, was named as a suspect and his conviction was later affirmed. In April 2026 KPK stopped the investigation of Siman after his death while saying the corporate case continued. The sources do not identify Dewa as a suspect or defendant; the summons is not evidence of wrongdoing.

Attribution: Individual involvement documented. The reviewed report documents witness status only. Later conviction reporting concerns Dody, and SP3 concerns Siman; neither is attributed to Dewa.

Relevance: Relevant compliance context for a current director whose 2023 public title was operations and production; the underlying matter predates that 2023 summons and individual culpability is not established.

Suitability for the current role

Engineering, economics and mine-safety experience align with a downstream strategy remit

Education through 2019; Vale roles through 2021; ANTAM director appointment 10 June 2026 · analyst inference · medium materiality

ANTAM reports a PhD in economics/business, master’s degrees in physical engineering and management, and a mechanical engineering degree. Its biography lists Vale roles including General Manager, Health, Safety and Operational Risk in 2020–21. The June 2026 GMS assigned him to a downstream strategy/operations portfolio. This supports relevant operations and commercial breadth, but source coverage does not establish individual delivery metrics.

Attribution: Responsibility not applicable. Career, degrees and certifications are issuer-reported and were not verified with awarding bodies or employers.

Relevance: Relevant operational and economic background for downstream strategy; exact contribution and current portfolio results remain unmeasured.

Evidence gaps

• The selected company roster title differs slightly from the June 2026 minutes wording (“Downstream Strategy & Downstream Operations”); role scope appears similar, but no separate dated title-change notice was reviewed.

• Independent evidence of individual operational, financial or safety outcomes in prior roles was not located.

• Witness status is the only personal connection found in the anode case; the outcome of the continuing corporate prosecution is beyond his individual role.

• No exhaustive legal, sanctions or credential verification was performed.

ANTAM reported 9M26 net profit of Rp9.66 trillion, up 46%, and EBITDA of Rp13.48 trillion, up 45%. His current Mineral Resources Management title was formalized in June 2026; the period partly overlaps his director tenure but the release does not isolate contribution.

Attribution: Role overlaps event; causation unproven. The director role overlaps part of the reporting period; causation is not established.

ANTAM reported zero fatalities and four medical-treatment cases in 2025

2025 · issuer reported · low materiality

The annual report lists zero fatalities and four Medical Treatment Cases for 2025 and reports a TRIR of 0.03. Hartono’s ANTAM operational leadership overlaps the year, but these are company-wide metrics; the report does not connect a specific safety result or incident to him.

Attribution: Role overlaps event; causation unproven. No individual act, control failure or causal contribution is established.

Relevance: Relevant oversight context for an executive with an operations background; not a personal safety record.

ANTAM reported Gold PROPER recognition for its Nickel Mining Business Unit and Precious Metal Processing & Refinery Business Unit and quoted Hartono. The source describes company/unit awards and does not isolate his personal contribution.

Attribution: Role overlaps event; causation unproven. The release quotes him but does not establish that he personally caused the awards.

Questioned as a witness in the 109-ton gold-management investigation

2010–2022 alleged events; witness examination 7 September 2023; convictions reported May 2025 · documented · medium materiality

IPOL reported that the Attorney General’s Office examined Hartono as a witness on 7 September 2023 in an alleged gold-business governance matter covering 2010–22; the report said no suspects had been announced at that time. Later ANTARA reports describe convictions of six former ANTAM precious-metals unit officials and seven private parties. Hartono is not among the named defendants in those reports. His witness examination does not establish an allegation or culpability.

Attribution: Individual involvement documented. Sources connect him to the investigation only as a witness. The later named defendants are distinct people; no personal charge or conviction against Hartono is established in reviewed materials.

Relevance: Relevant governance context given his later operating/director roles; individual involvement beyond witness evidence remains unproven.
