Listen to the news

AGL Energy (ASX:AGL) is back in focus after reaffirming its shift away from coal, while its chief executive pressed for gas to be included in renewable subsidy schemes to support grid reliability.

Recent trading shows AGL Energy shares pulling back 1.8% over the past day, following a 4.7% 7-day share price return and a 5.8% 90-day gain. Meanwhile, the 1-year total shareholder return of 3.3% and 5-year total shareholder return of 79.2% suggest that longer term holders have seen stronger rewards than recent short-term momentum implies.

After that long run and a softer year to date, the real question is whether AGL Energy’s coal exit and gas push still leave meaningful upside, or if the easy part of the rerating is already behind it.

Most Popular Narrative: 12% Undervalued

AGL Energy last closed at A$8.74 compared with a widely followed fair value estimate of A$9.91. The gap partly reflects how much faith investors put in its shift toward renewables and firming assets.

Significant investment in grid-scale battery developments and firming capacity is positioning AGL to capture revenue and earnings growth as electricity demand rises from electrification of homes, industry, and transport. As these assets come online through FY26 to FY28, they are expected to more than offset the decline in coal and gas earnings from asset retirements and contract expiries, supporting future EBITDA growth and earnings stability.

See why 64 investors see AGL Energy as 12% undervalued.

Result: Fair Value of A$9.91 (UNDERVALUED)

Still, heavy spending on grid-scale batteries and digital projects, along with pressure on retail margins, could tighten cash flow and test AGL Energy’s transition thesis.
