Drax Group shares have drifted lower through the summer, with a screener snapshot flagging a roughly 3% fall and the stock changing hands around 716p in early August. The FTSE 250 power generator faces a pivotal question: as its lucrative biomass subsidies wind down towards 2027, can it still justify a premium rating? We separate the confirmed facts from the market noise.

Introduction

Drax Group plc (LSE: DRX) is one of the more divisive names in the FTSE 250. To supporters it is a dependable, dividend-paying operator that helps keep the lights on when the wind stops blowing; to critics it is a subsidy-dependent biomass burner whose business model faces a cliff-edge at the end of 2027. A recent market snapshot flagged the shares down about 3%, and by the close on 3 August 2026 the stock stood at roughly 716p, valuing the company at about £2.4bn.

That headline percentage is a point-in-time reading rather than a verified single trading session, so it is worth asking what has actually changed — and whether Drax’s rating is genuinely at risk. This article distinguishes the snapshot move from the latest price and the longer-term trend.

The share-price move in context

The 3% figure in the headline should be read as a screener snapshot rather than a confirmed one-day move. What is verifiable is that the shares have been sliding: market data showed Drax at around 764p on 24 July 2026, easing to about 716p by 3 August, a drift of roughly 6% over that stretch. The stock has traded between a 52-week low near 614p and a high of around 937p, so the current level sits in the middle of its range.

Past performance is not a reliable indicator of future results, and short-term moves in a mid-cap stock can reflect index flows, thin summer volumes or profit-taking as much as fresh news. No single company-specific catalyst had been officially confirmed at the time of writing.

What Drax actually does

Drax Group runs the UK’s largest power station, near Selby in North Yorkshire, where units that once burned coal now burn compressed wood pellets, known as biomass. It also owns Cruachan, a pumped-storage hydro plant in Scotland — effectively a giant water battery that pumps water uphill when power is cheap and releases it through turbines when demand spikes — and it manufactures wood pellets in the US and Canada. More recently it has added flexible gas peaking plants and battery projects.

The controversy centres on biomass. Drax has historically earned a large share of its profits from renewable subsidies, chiefly Renewable Obligation Certificates (ROCs) and a Contract for Difference (CfD) — government schemes that top up the price it receives for power classed as renewable. Those legacy subsidies expire in 2027, which is why the company’s post-2027 economics dominate the investment debate.

The 2027 subsidy cliff and the bridging deal

This is the crux of the case. In February 2025 the UK government and Drax agreed a new ‘low-carbon dispatchable’ Contract for Difference to bridge 2027 to 2031, once the existing ROC and CfD support ends. Under the arrangement Drax’s biomass units are expected to run far less often — broadly around half of their historic output — operating in a flexible, back-up role rather than as constant ‘baseload’ generation, and using only biomass that meets tighter sustainability criteria.

The support price is lower than under the old schemes, and a mechanism shares excess profits with consumers. In plain terms, Drax swapped a richer but expiring subsidy for a leaner, more secure one running four more years. What happens after 2031 remains open, and that uncertainty is much of why the market discounts the biomass earnings.

Building a business beyond biomass

Management’s answer to the 2027 problem is diversification. Drax has been commissioning flexible open-cycle gas turbine (OCGT) plants — quick-start gas units that earn money through the Capacity Market, the scheme that pays generators to be available at peak demand — including a new South Wales site commissioned in May 2026. It has also signed tolling agreements for grid-scale battery storage and, on 1 June 2026, announced an agreed offer to acquire Bluefield Solar Income Fund in a deal valued at around £561m.

The group also continues to promote plans for BECCS — bioenergy with carbon capture and storage — which would capture the carbon dioxide released when biomass is burned and store it underground, in theory making the plant ‘carbon negative’. BECCS remains dependent on further government support and has yet to reach a final investment decision, so it is best treated as an option on future policy, not a committed earnings stream.

Cash returns and the valuation debate

For income investors, Drax has been generous. Full-year results for 2025, published on 26 February 2026, showed revenue of about £5.39bn, down 12.5% as power prices normalised, and pre-tax profit of £189.5m, sharply lower than the prior year; reported earnings per share were 137.7p and the dividend was raised 11.5% to 29p. The company has also been running a share buyback, repurchasing its own shares almost daily through early 2026 to return surplus cash and reduce the share count. On the reported numbers the shares yield around 4.2%.

The bull case is that this cash generation and the diversification pipeline are being under-valued. The bear case is that a headline price-to-earnings ratio well above the market average — inflated by the slump in 2025 statutory profit rather than reflecting an expensive stock in normalised terms — signals a premium that could unwind if the post-2031 outlook darkens. Any valuation drawn from a single year of depressed profit is an estimate, not a precise gauge.

The risks investors should weigh

Policy is the dominant risk. Drax’s economics depend heavily on government decisions — subsidy levels, any framework beyond 2031, Capacity Market auctions and the fate of BECCS — and political appetite for burning imported wood remains contested on both cost and environmental grounds. Correlation is not causation: a soft share price does not by itself prove the market has turned against the strategy, just as a strong one would not vindicate it.

Regulatory scrutiny has been a recurring theme, though the Financial Conduct Authority closed an investigation into the company in June 2026 with no action taken. Execution risk on the acquisitions and new-build projects, commodity-price swings and the durability of the dividend are the other factors to weigh.

What to watch next

The near-term signposts are clear enough: half-year results for the six months to 30 June 2026, the pace of the buyback, any detail on support beyond 2031, and progress integrating Bluefield Solar. For now, the modest share-price weakness looks more like a re-rating of a policy-sensitive utility than a response to any single confirmed event.

Whether Drax’s valuation is truly ‘at risk’ depends less on this month’s price action than on those longer-term answers.
