• Experienced interim CFO appointment: Michael Mott has prior CFO and senior finance roles in the energy sector

Insights

Corporate Governance Specialist

TL;DR: A planned CFO departure with a short consulting overlap reduces disruption risk.

The company reports a voluntary resignation by the CFO effective October 20, 2025 with a consulting arrangement through December 31, 2025, which preserves continuity for financial reporting and close processes. Naming an internal interim officer avoids an immediate external hire while the search proceeds.

The interim CFO, Michael Mott, has prior executive finance experience including a CFO role at LNG Limited and long tenure in energy-sector finance; this background mitigates near-term execution risk for reporting and treasury functions. Investors should track the timeline and profile of the permanent CFO search over the next quarters.

Finance Succession Analyst

TL;DR: Interim appointment is experienced but temporary; key risks are continuity and disclosure timing.

Mr. Mott's background includes CFO duties at LNG Limited and senior finance and strategy roles at BG Group and Dynegy, supporting his capability to act as interim principal financial officer. The consulting arrangement with the departing CFO through December 31, 2025 provides overlap for handoff of responsibilities.

Material items to watch in the near term include any changes in financial controls or reporting responsibilities disclosed before the next quarterly report and the eventual appointment of a permanent CFO, which could influence investors' view of financial leadership stability within the next 3-6 months.
