UKW — GREENCOAT UK WIND PLC

Executive summary

Greencoat UK Wind is a UK-listed renewable infrastructure investment trust owning stakes in 49 operating wind farms (1,942MW net generating capacity, ~6% of UK installed wind), structured as an investment trust with external management by Schroders Greencoat. Over the five-year filing window the trajectory has been one of portfolio growth (via equity raises in 2021 and Hornsea 1 acquisition in 2022) followed by NAV compression as higher discount rates, falling power-price forecasts, and the RO→CPI indexation change pulled NAV per share from 167.1p (Dec-2022) → 151.2p (Dec-2024) → 133.5p (Dec-2025) → 134.1p (Jun-2026); the Board has shifted from growth to balance-sheet repair (£222m of disposals announced to date), buybacks, and selective reinvestment. The single most important point for valuation today is that the stock trades at a c.14% discount to a NAV built on an 11.5% levered IRR with a prudent capture-discount buffer — the question is whether that discount is a value opportunity or structural reflection of policy/power-price risk.

Fair value estimate

Methodology: NAV with sector-discount cross-check, since UKW is an investment trust whose underlying DCF-based NAV is itself the primary valuation. Current NAV is 134.1p (unaudited, 30 June 2026).

Key assumptions underlying NAV:

• Levered portfolio IRR 11.5% (unlevered 9%; 35% gearing at 5% cost)
• Power price forecasts from leading consultant with 12% capture discount
• Asset life 30 years; blend of ROC/CFD/merchant revenues (~66% of 2026 revenues fixed)
• CPI 3.57% (2026) → 2.5% long-run

Cross-check — dividend yield: at 115p and a 10.7p 2026 dividend, implied yield is 9.3% (dividend cover 1.9x). Peers trade at ~8–11% yields.

Fair value range: 120p – 140p per share (vs. 134.1p NAV)

• Low: 120p — reflects persistent sector discount, modest NAV erosion risk from any further rate rise or policy shock
• High: 140p — assumes modest discount narrowing as the listed renewable trust sector consolidates and 2026 cash delivery lands at top of guidance

Implied market cap range: £2,590m – £3,020m (mid ~£2,805m) Current market cap: £2,437m → absolute upside ~15% to the midpoint (upside to NAV ~17%, upside to high case ~22%).

Sector context

Classified as Financials / Financial Services (ICB) because it is an investment trust vehicle, not an operating utility. Within the UK listed-renewables peer group — Renewables Infrastructure Group (TRIG), Octopus Renewables (ORIT), Foresight Solar (FSFL), Downing Renewables, Bluefield Solar — UKW is the largest, lowest-cost, and highest-return vehicle. Fee structure recently improved to the lower of market cap and NAV (sector-leading alignment). Quality is above-peer; leverage (41.7% GAV) is in-line; growth outlook is now below-peer because the Board has pivoted to disposals and buybacks rather than acquisitions.

Investment thesis (3 bullets)

• Durable, inflation-linked cash generation at a 24% discount to a conservatively struck NAV. H1 2026 cash generation of £222m produced dividend cover of 1.9x; full-year on track for top of £350–410m guidance range 2026-07 half-year. The 2026 dividend of 10.7p is the 13th consecutive inflation-linked rise 2026-02 final results, 2026-07 half-year.
• Balance-sheet repair is credible and funded by cash flow, not dilution. 2025 saw £181m disposals at NAV plus £109m buybacks; the Board expects ~£1bn of excess cash over the next five years and the June 2026 refinancing was oversubscribed by existing lenders at a weighted 5.1% cost — demonstrating lender appetite despite sector pressure 2026-07 half-year, 2026-02 final results.
• Policy tailwinds are coming into focus. UK electrification requires 50–100% more electricity by 2040 driven by EVs, heat pumps and data centres; AR7 (2026) priced offshore CFDs at £89.50–91.20/MWh, well above UKW's modelled merchant assumptions, supporting medium-term power-price floors 2026-02 final results.

Key risks (3 bullets)

• Power-price risk is the dominant NAV driver. 2025 NAV fell £28p/share largely because of lower long-dated gas-price forecasts; a ±10% power-price shift moves NAV by ±13.6p (c.10%). Merchant exposure is c.34% in 2026 but rises as subsidy periods roll off 2026-02 final results, 2026-07 half-year.
• Discount rate / interest rate risk. The portfolio levered IRR was raised from 10% → 11.5% in the past three years; a further 0.75% rise would knock 5.6p off NAV. Long-dated gilt rates remain elevated and the sector trades at persistent discounts to NAV 2026-07 half-year, 2026-02 final results.
• Externally managed structure with wind-resource variability. 2025 generation ran 8.5% below budget on low wind; this is normal statistical variance but creates earnings volatility. The investment trust is not operationally managed in-house — all operational performance depends on O&M counterparties and the asset manager 2026-02 final results.

Operating leverage

Operating leverage for UKW is moderate and asymmetric to power prices only. The cost base is dominated by O&M, insurance, management fees and interest — all largely fixed in £ terms. H1 2026 operating expenses at wind-farm SPV level were £118.8m against revenue of £483.2m, implying a wind-farm EBITDA margin around 56% and a Group-level net cash margin around 46%. Because the generation volume is wind-dependent and fundamentally capped by installed MW, there is no "capacity to deliver more volume than planned" in the way an asset-light software business can — the uplift path is price, not volume. On price, however, incremental power prices above the forecast curve drop through almost entirely to free cash flow (the £10m annual Electricity Generator Levy allowance is now expired post-March 2028). The merchant portion of revenues (currently 34% in 2026, rising thereafter as ROC/CFD contracts roll off) is where meaningful operating leverage sits. A 10% power-price surprise ≈ 13.6p/share NAV uplift (~10% of NAV), consistent with roughly 1x operating leverage on price surprises — not the "multiples of profit" the investor profile seeks. 2026-07 half-year sensitivity table

Value-trap signals

• Repeated power-price-driven NAV writedowns across 2024 and 2025 (even if partially reversed in 2026)
• Pivot from growth to divestment / buybacks suggests limited accretive investment opportunities at the current cost of capital
• Externally managed structure with ~0.73% ongoing charge persists
• Three consecutive AGM continuation votes due to discount >10%
• RO→CPI reindexation in 2026 was a one-off regulatory downgrade (cost ~£57m to NAV); further regulatory tinkering (REMA, zonal pricing) remains a tail risk

Not terminal, but these signals explain the persistent sector discount and argue against the discount closing quickly.

Earnings vs. expectations

Over the window, UKW tends to miss on generation (wind below long-run average 7 of the last 10 years) but meet or beat on cash generation because high power prices compensate for low wind. 2022: generation 5% below budget, cash cover 3.2x on dividend (massive beat on gas-driven power prices). 2023: generation 13% below budget, cash cover 2.1x (beat). 2024: generation 11% below budget, cash cover 1.3x (in line). 2025: generation 8.5% below budget, cash cover 1.3x (in line, but NAV reset lower). H1 2026: generation 4.9% ABOVE budget, cash cover 1.9x — on track to deliver top of £350–410m guidance. Net pattern: operational misses on wind, offsetting beats on power price, delivering reliably on dividend commitment with high cover. Analyst consensus is not quoted in filings.

Conviction

Conviction: 4 (high)

Anchors: (i) NAV is published quarterly with full disclosure of discount rate, inflation, power-price curve, energy yield and asset-life assumptions, with sensitivity tables; (ii) 13 years of consistent dividend delivery and 1.9x cover; (iii) cash generation is actual, not accounting, and reconciles to statutory cash flow.

Limits: (i) NAV is itself a DCF model with ±10–15% uncertainty from power-price assumptions alone; (ii) the sector discount is politically and interest-rate sensitive and could persist or widen.

Driver scoring and overall fit

This is a defensive income infrastructure vehicle with marginal AI exposure, limited operating leverage, and fair pricing. For the investor profile — AI receivers with operating leverage at fair prices — this is a poor thematic fit. The data-centre electricity-demand angle is real but diffuse: UKW doesn't sell directly to AI/hyperscalers at premium prices, and its merchant exposure captures only a fraction of any power-price uplift. The quality of the business (strong downside protection, inflation-linked income, 9%+ yield) is high, but the long-tail-upside optionality the strategy requires simply isn't here.
