• ROM coal mined recovered strongly late in the quarter as adverse weather conditions subsided
• Saleable production of 3.2Mt remained broadly steady year-on-year
• Closing consolidated cash of US$166 million, corresponding to net debt of US$79 million

The first quarter of 2026 reinforced the resilience of Stanmore Resources' business, with operations recovering strongly in the latter part of the period to deliver saleable production within the expected annual run rate of Guidance. This followed the arrival of ex-Tropical Cyclone Koji in early January, which caused widespread disruption across open-cut producers in Queensland. Strong opening inventories helped buffer the impact for Stanmore, supported by a proactive operational response to prioritise coal availability and record volumes at South Walker Creek in March. Metallurgical coal prices improved quarter-on-quarter amid the weather-related supply constraints, although gains were moderated by ongoing macroeconomic uncertainty associated with the conflict in the Middle East. Stanmore closed the quarter with US$166 million in cash, which, together with available liquidity of US$270 million, provides a strong platform to navigate this period of heightened volatility, while maintaining focus on delivery of the full year operational plan.

Saleable production Guidance maintained at 12.8 - 13.4Mt, with record performances in March providing a strong base for the remainder of the year. FOB Cash Cost Guidance revised to US$98 - US$103 per tonne to reflect macroeconomic impacts, including fuel price risk arising from the ongoing Middle East conflict and foreign exchange rates.
