## Business failures and setbacks

### 2025 feasibility study production target was retracted and later replaced [bill_guy_tgm_production_target_retraction]

30 September 2025–3 February 2026 · documented · medium materiality

Theta’s October 2025 prospectus reproduces its 3 October ASX retraction: the company said it did not have a reasonable basis for the Base Case production target and forecast financial information in the Optimised Feasibility Study released three days earlier, and expressly cautioned investors not to rely on it. On 3 February 2026 Theta issued a Revised Feasibility Study with a new mine plan and financial estimates, including an Ore Reserve Plan as well as a Base Case containing Inferred Resources; the report itself says the Base Case cannot be guaranteed and Inferred Resources are speculative. This is a material disclosure and project-planning failure followed by revised disclosure.

**Attribution:** Role overlaps event; causation unproven. This company-level event occurred during the executives’ reported Theta roles. Reviewed evidence does not show which individual prepared or approved the retracted target, and does not establish personal fault; attribution is limited to role overlap and team oversight.

**Relevance:** Relevant to oversight of technical disclosure and feasibility-study governance during a development decision; subsequent revision addressed the public information but does not erase the original correction.

## Suitability for the current role

### Role fit and evidence limits [bill_guy_role_fit]

Assessment at cutoff 2026-10-09 · analyst inference · medium materiality

Project construction and South African operating experience described for Guy and Du Triou is relevant to the TGME build and commissioning phase; direct attribution to Theta delivery milestones remains limited.

**Attribution:** Responsibility not applicable. This is an analytical inference from the cited career profile and the company’s stated stage; it does not claim personal causation of company outcomes.

**Relevance:** Connects prior experience to the role’s execution and oversight needs.

## Evidence gaps

- The reviewed public professional and issuer materials did not establish verified degrees or professional credentials for this executive.

- Exact dates for prior roles and independent confirmation of profile claims were unavailable in the reviewed materials.

- Issuer leadership page labels the Executive Director of Finance role as “Executive Director”; no dated announcement resolving the title difference was found.

- The reviewed ASX/issuer disclosure establishes the company’s production-target retraction and later revised study but does not identify which executive prepared or approved the September 2025 target or the decision process leading to its publication.
