FY2025 EBITDAF guidance revised to $760m

Mercury announced today that it has revised its FY2025 EBITDAF guidance from $820m to $760m. This reflects an expected 150GWh decrease in full year hydro generation to 3,400GWh owing to continued dry weather in the Taupō catchment, and projected below mean hydro inflows and lake level through to 30 June 2025. FY2025 ordinary dividend guidance remains unchanged at 24.0 cents per share and stay-in-business capital expenditure guidance remains unchanged at $150m. Guidance may change and remains subject to any material events, significant one-off expenses or other unforeseen circumstances including changes to hydrological conditions.
