AGL Energy Ltd (AGL.AU) shares plunged 8.71% in intraday trading following the release of its fiscal year 2025 results and guidance for fiscal year 2026. The sharp decline comes as investors digest disappointing financial performance and a less optimistic outlook for the coming year.

The Australian power producer reported a net loss of A$98 million for the fiscal year ended June 30, 2025. While the company's adjusted net income came in at A$640 million, it fell short of analysts' expectations of A$649 million. The underwhelming results were attributed to lower wholesale electricity prices and reduced consumer margins, resulting in a 21.2% drop in underlying profit compared to the previous year.

Adding to investor concerns, AGL provided a cautious outlook for fiscal year 2026. The company forecasts underlying net profit after tax to be between A$500 million and A$700 million, with the midpoint falling below the consensus estimate of A$667.8 million. AGL cited higher operating and finance costs due to increased investments and total borrowings as factors contributing to the lower profit expectations. Furthermore, the company slashed its final dividend to 25 Australian cents per share, down from 35 cents in the previous year, potentially disappointing income-focused shareholders.
