DRX
Utilities Market cap £2.7bn Overall fit 470 /1000

Partial fit: valuation is fair-to-attractive and balance sheet is fortress-quality, but the AI-beneficiary angle is indirect (potential data-centre PPA host post-2027) rather than direct, and operating leverage is capped by the CfD price ceiling and physical generation limits. A 'right quality, weak AI angle' name rather than a top-band fit.

Fair value range 900p–1,100p Mid case · £3.4bn
Absolute upside +26.2% vs current market cap
Conviction 3/5 confidence in undervalued call
Supports the call
  • CfD + Capacity Market contracts provide visible £600-700m EBITDA floor to 2043
  • 1.1x net debt/EBITDA balance sheet with disciplined £450m buyback
  • Clean disclosure and consistent management execution
Limits the call
  • FY2026 EBITDA steps down sharply (£902m to £665m) and merchant uplift assumption is key
  • Data-centre and BECCS optionality is real but unscheduled and unvalued
Methodology

Sustainable post-2027 EV/EBITDA at 6.0-7.0x, cross-checked vs FCF yield

In one line · bull case

A contracted-cash-flow UK utility with a fortress balance sheet, real (if indirect) AI/data-centre optionality, and a fair-to-cheap valuation versus its post-2027 £650m sustainable EBITDA floor.

In one line · biggest risk

The 2026 earnings step-down is material and visible, and the post-2027 CfD economics underpinning the £600-700m floor have limited margin of safety if merchant uplift disappoints.

Drivers
AI beneficiary 40 /100
Indirect: could host >1GW data centre at Selby site post-2031 and supplies dispatchable power needed for AI buildout, but not in the AI supply chain itself.
Operating leverage 45 /100
Asset-heavy with high fixed costs but capped by physical generation limits and CfD price ceiling; Cruachan and BESS have higher leverage than biomass.
Earnings vs expectations 60 /100
Consistently met or modestly beat consensus during 2022-25 high-price period; FY2024 and FY2025 both delivered 'top end of consensus'.
Growth momentum 40 /100
Mid-cycle EBITDA stepping down from £1bn+ peak to £600-700m post-2027; growth optionality from BESS, data centre and BECCS is real but back-end loaded.
Moat 60 /100
Drax Power Station is genuinely unique (UK's largest renewable by output); Cruachan is one of only four UK pumped-storage sites; long-term CM and CfD contracts to 2043 create regulatory moat.
Earnings quality 60 /100
Heavy use of Adjusted EBITDA with regular exceptionals and certain remeasurements; significant working-capital swings from ROC assets; generally clean PwC-audited statutory results.
Management quality 70 /100
Disciplined capital allocation: £472m buybacks since 2017, dividend growth ~11% pa, walked away from HEIT acquisition at right price, executed Pinnacle integration successfully.
Cyclicality 45 /100
Moderately cyclical via power prices and weather (wind/hydro); CfD and Capacity Market dampen this materially from 2027.
Leverage 25 /100
Net debt/EBITDA 1.1x at H1 2025, well below 2x target; substantial liquidity headroom (£726m cash and committed facilities).

DRAX GROUP PLC (DRX) — Investment Research Note

Executive summary

Drax operates the UK's largest single source of renewable power by output (a 2.6GW biomass-converted power station at Selby), alongside a portfolio of pumped storage/hydro, three new-build OCGTs, a growing battery storage business, and ~5Mt of North American wood pellet production capacity. Over the five-year filing window the Group has transformed from a coal-heavy generator into a flexible renewable platform, monetising historically high power prices in 2022-25 (peak FY2024 Adj. EBITDA £1,064m), returning ~£472m of buybacks since 2017 (with a further £450m programme underway), and securing a UK Government CfD to underpin biomass generation from April 2027 through March 2031. The single most important point for valuation today is the visible step-down in earnings as the RO scheme ends and the lower-priced CfD takes over — consensus Adj. EBITDA falls from £902m (2025) to £665m (2026), and management targets £600–700m pa post-2027 — so the question is how much of the contracted £3bn 2025-2031 free cash flow target is already priced in.

Fair value estimate

Methodology: Blended EV/EBITDA on sustainable post-2027 earnings, cross-checked against free-cash-flow yield.

Key assumptions:

  • Sustainable Adj. EBITDA post-2027: £650m (midpoint of company £600–700m guidance, before development expenditure) 2025-12 trading update
  • £650m of index-linked Capacity Market agreements underpinning earnings to 2043 2026-04 trading update
  • ~£300–350m sustainable post-tax operating free cash flow (after maintenance capex of ~£110m, interest ~£55m, tax ~£100m, excluding the one-off c.£500m RO working-capital inflow)
  • Net debt ~£1.0bn (Net debt:Adj. EBITDA 1.1x at H1 2025)
  • 336.2m voting shares
  • EV/EBITDA range 6.0–7.0x — consistent with UK regulated/contracted utility comparables given long-dated capacity contracts but lower than pure regulated networks

Calculation:

  • Mid-cycle EBITDA £650m × 6.0–7.0x = EV £3.9bn – £4.55bn
  • Less net debt £1.0bn = Equity £2.9bn – £3.55bn
  • Per-share: 860p – 1,060p, midpoint ~960p
  • FCF cross-check: £325m sustainable FCF at 8–10% yield = £3.25bn–£4.06bn equity = 965p–1,210p

Fair value range: 900p – 1,100p per share, midpoint 1,000p Implied market cap: £3,025m – £3,700m, midpoint £3,360m

Versus current market cap of £2,970.8m (884p): central upside ~13%, range -2% to +24%.

View: fair-to-modestly undervalued — the market is broadly pricing in the post-2027 step-down but giving limited credit to the data-centre option, FlexGen growth, or Cruachan refurbishment.

Sector context

  • Sector classification confirmed: Utilities (ICB). Drax sits at the more "merchant/IPP" end of the sector — contracted (CfD + Capacity Market) earnings are higher than a generic IPP but lower than a regulated network operator.
  • Quality profile is above typical merchant generators (long-dated CM contracts, CfD floor, strong balance sheet at 1.1x leverage) but below pure regulated utilities. Growth profile is flat-to-modest given the 2026-27 earnings reset.
  • Listed peers: SSE plc (more diversified networks + renewables), Centrica (supply + generation), and on the storage angle Gore Street Energy Storage Fund and Harmony Energy Income Trust (which Drax attempted to acquire then walked away from at 88p 2025-05 offer-lapsed announcement — a useful capital-discipline data point).

Investment thesis

  1. CfD + Capacity Market + Cruachan = ~£650m of high-visibility contracted earnings underpinning a 1.1x leveraged balance sheet to 2043. The 4-year CfD at £109.90/MWh (2012 real) for ~6TWh pa from Drax Power Station, combined with c.£650m of index-linked Capacity Market agreements, provides far more earnings visibility than a typical UK utility 2025-12 trading update, 2026-04 trading update.
  2. FlexGen optionality (BESS + data centre + Cruachan II) is genuinely incremental. £500m committed to ~710MW/1.8GWh of BESS by 2027–28, plus the Flexitricity AI-optimisation platform, plus a planning application for an initial 100MW data centre at the Selby site with ambition to grow to >1GW post-2031, including a contractual right to direct up to 500MW of Drax Power Station output to a data centre during 2027–31 2026-01 Flexitricity acquisition, 2025-12 trading update.
  3. Capital return discipline is real and creating per-share value. £300m buyback completed October 2025, second £450m programme underway, dividend up ~11% pa since 2017, total dividend 29.0p for FY2025. Management walked away from the HEIT BESS portfolio at 88p when Foresight overbid — a useful demonstration that the £450m buyback isn't constrained by acquisition urgency 2025-05 offer-lapsed announcement, 2025-07 half-year.

Key risks

  1. 2026 is the visible earnings cliff. Consensus FY2026 Adj. EBITDA £665m vs. FY2025 £902m as the RO scheme winds down and the lower-priced CfD takes over — any deeper-than-expected drop, particularly if biomass costs stay elevated, hits both leverage covenants and the £450m buyback pace 2026-04 trading update.
  2. Biomass sustainability and regulatory risk persists. Ofgem's investigation into RO biomass profiling closed in 2024 with a £25m voluntary redress payment but no ROC clawback; NGO scrutiny of US South sourcing is ongoing, and the EU's REDIII implementation, UK Government policy on a "bridging mechanism" to BECCS, and ongoing political risk around biomass subsidies create binary regulatory tails 2024-11 trading update.
  3. OCGT/BESS execution risk and Cruachan grid-failure incident. All three OCGT projects (c.900MW) have already slipped from 2024 to commissioning across 2025–26 due to third-party grid delays, and an SPEN grid-connection failure has caused an ongoing forced outage on Cruachan units 3 and 4 since late December 2025 — these reveal Drax's dependence on third parties for project delivery 2026-04 trading update, 2025-07 half-year.

Operating leverage

Drax has moderate operating leverage, less than a pure-software business but more than a typical industrial. The fixed cost base of Drax Power Station is large (the H1 2025 cost commentary flagged higher labour and biomass-handling fixed costs even at unchanged output), and the Cruachan/hydro portfolio is highly fixed-cost (Adj. EBITDA of £64m on relatively small revenue, with planned outages adding to swings). However, two structural ceilings limit the upside-leverage story: (1) the biomass units are capacity-limited (~13–14TWh of physical output ceiling) and (2) the CfD caps the price upside on c.6TWh pa from 2027. So an unexpected revenue surprise of +10-20% from generation is largely a function of power-price spikes that get captured only on hedge roll-off, rather than incremental volume drop-through. The clearest operating-leverage levers are (a) Cruachan capacity utilisation (system-stress events have driven this from H1 2023 £141m to H1 2025 £64m — i.e. >2x sensitivity to volatility) and (b) the BESS/Flexitricity platform, which is capital-light once built and where arbitrage spreads drop almost fully to gross margin. A 10–20% revenue beat above plan would add perhaps 25–40% to Adj. EBITDA — meaningful but not multi-bagger. 2025-07 half-year, 2026-04 trading update

Value-trap signals

  • Sequential ratings risk on biomass sustainability (Ofgem investigation closure 2024 with redress payment is a watch-item, not a clean bill of health) 2024-11
  • 2026 EBITDA cliff is large and visible — if the central CfD economics underperform the £100–200m pa biomass-generation EBITDA target, the £600–700m post-2027 floor is at risk 2025-07 half-year
  • Long-tail BECCS dependency: ~£3-7bn of strategic capex hopes rest on UK Government policy support that is still in consultation; a hard "no" on BECCS bridging mechanism would shrink long-term EBITDA prospects 2025-12, 2026-04
  • Generally none of the canonical traps apply: no declining revenue trend (FY2024 revenue £6,163m), no rising debt without growth, dividend is growing not cut, no obvious related-party concerns, no terminal-decline industry.

Overall: a few watch-items but no value-trap signature.

Earnings vs. expectations

The five-year filing record shows Drax mostly meeting or modestly beating consensus. Notable data points: FY2024 Adj. EBITDA guided "around top end of consensus" in November 2024 against £1,004m consensus (range £993–1,039m), and the company delivered. FY2025 was again guided "around top end" of £902m consensus (range £892–909m) in December 2025. H1 2025 Adj. EBITDA was £460m vs. H1 2024 £515m, with the company reiterating full-year expectations. FY2026 is currently guided "in line with consensus" of £665m. The pattern is small beats during the high-price 2022–24 environment, with operational misses (OCGT grid delays, Cruachan grid failure) handled by reprofiling rather than by guidance cuts. 2024-11, 2025-12, 2026-04

Conviction

Conviction: 3 (moderate)

Anchoring factors: (1) the CfD + Capacity Market provide a hard floor on post-2027 earnings; (2) clean PwC-audited disclosure with consistent APM definitions; (3) management's £450m buyback discipline and the walk-away from HEIT signal genuine capital discipline.

Limiting factors: (1) the 2026 step-down magnitude is sensitive to assumptions about merchant uplift above the CfD cap and biomass cost trajectory, both of which have been volatile; (2) the >£500m of BESS/Flexitricity/OCGT capex is unproven at scale; (3) the data-centre option could be material but is essentially unvalued and unscheduled.
