Regulators, Not Results, Are Driving The AGL Energy Debate

Fund managers are split on whether a new battery plant can offset falling coal earnings and tighter retail tariff settings

11 May 2026 · 3 min read

Regulatory tariff settings, not earnings surprises, have driven most of the recent commentary on AGL Energy. Pendal Group's May 2026 newsletter said the energy retailer pulled up the bottom end of its own guidance only marginally, with consensus sitting closer to the top of the range, while flagging that preliminary FY27 guidance was qualitatively soft, pointing to the outcome of the Domestic Market Obligation as well as broader local and global influences.

That followed a similar pattern through the March 2026 quarter, when Pendal tracked two separate regulatory releases affecting AGL's retail margins. The draft Default Market Offer, released mid-quarter, pointed to retail tariffs falling between 2 and 10 per cent depending on state and customer type, which the manager said represented a headwind to retailer margins but a tailwind for consumers and the broader inflation picture. The subsequent confirmation of the Victorian Default Market Offer for 2026-27 firmed up the numbers further, with Victorian households and small businesses expected to see bill relief in FY27 of 2 to 3 per cent and 4 to 5 per cent respectively, driven by lower environmental cost pass-through, while Pendal noted allowable retail margins were left unchanged at 5 per cent.

Victorians should see some electricity bill relief in FY27, with bills 2-3% lower in retail and 4-5% lower for small business, driven by lower environmental cost (LRECs) pass through.

The case for coming back in

Not every manager has been positioned defensively through this. Quest Asset Partners rejoined AGL in September 2025 after having exited the position back in 2024, noting the stock was down more than 20 per cent since that exit, against a 15 per cent rise for peer Origin Energy over the same period. The manager's thesis was that AGL's forecast earnings from its new South Wales battery plant should more than offset the headwind from an expiring, very low-cost coal supply contract at its remaining NSW coal-fired generator. Quest also pointed to a broader structural tailwind, arguing that the build-out of AI infrastructure requires significant amounts of power and is increasingly cited by data centre operators as one of the primary constraints on their growth, a dynamic it sees as supportive for electricity generators over time.

That view sits in contrast to Paradice Investment Management, which exited its AGL position in September 2025 citing concerns about the earnings impact of the company's transition phase as it moves away from coal generation, a reminder that the same regulatory and generation-mix backdrop is being read quite differently depending on the manager's time horizon.

What's ahead

With the Domestic Market Obligation outcome still to be finalised and FY27 guidance described by Pendal as only qualitatively soft rather than quantified, the near-term focus for managers is on how much of the recent tariff relief flows through to AGL's retail margins versus being absorbed by consumers, and whether the NSW battery plant delivers the earnings offset Quest is banking on as the low-cost coal contract runs down.
