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.

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.
