Ørsted's Tax Loss and the Story That Really Matters

A headline claiming Ørsted "wins" a key European tax ruling on UK offshore wind farms got enough attention to circulate through energy investing circles. The problem: the UK Supreme Court actually ruled against Ørsted. On April 15, 2026, it unanimously denied the company tax relief on roughly £48 million of pre-development survey and study costs for four UK offshore wind projects. Environmental studies and engineering feasibility work, the court held, are too far removed from the physical installation of wind turbines to qualify for capital allowances — a depreciation deduction that reduces taxable income.

Ørsted called the decision "regrettable" and warned it damages the business case for UK offshore wind. The company is right about the sector impact but misleading about its own exposure. The £48 million at stake is small compared to the financial rebuilding that has actually defined Ørsted over the past two years — and the structural question for investors isn't about a single tax ruling. It's whether the company's turn from deep red ink back to positive cash flow can hold.

The Ruling in Context

Capital allowances work like this: when a company spends money on qualifying plant and machinery, it can deduct a portion of that cost against taxable profits each year, lowering its tax bill. The UK's Capital Allowances Act requires the spending to be "on the provision of" the plant — close enough to the physical asset that the law treats it as part of the same expenditure.

Ørsted spent £48 million on environmental surveys, geotechnical studies, and technical reports before building wind farms at sites including West of Duddon Sands (108 turbines near Barrow-in-Furness) and Gunfleet Sands, part of a total capital program exceeding £2 billion. The company argued these studies were essential prerequisites and should be treated as part of the plant's cost. The Supreme Court said no. Citing precedent going back to 1978, the judges drew a "limiting curve" around what counts as expenditure directly on the plant itself. Surveys that inform design decisions fall outside that line.

The Court of Appeal had ruled in Ørsted's favor in March 2025, which may be the source of the "win" narrative. The Supreme Court reversed that decision. This isn't about regulatory bias or an anti-renewable agenda — it's a narrow statutory interpretation that applies to any infrastructure project where pre-development work precedes physical construction. The UK government has promised a consultation on pre-development tax treatment to address the broader economic impact, but no legislative fix has been enacted.

For Ørsted's bottom line, the direct hit is material in name only. The company said the financial impact on the affected projects is "limited." £48 million is roughly 0.2 percent of Ørsted's 2025 core EBITDA of 25.1 billion kroner ($3.7 billion). The real damage is prospective: future UK offshore wind projects now carry higher effective development costs unless Parliament acts.

The Actual Financial Story

That limited direct impact matters because it contrasts sharply with the financial earthquake Ørsted has been working through. The company spent 2023 and 2024 absorbing over $16 billion in impairments — write-downs tied to surging interest rates that crushed offshore wind project economics, the collapse of U.S. deals like Ocean Wind, and a broader reassessment of its growth trajectory. The stock fell roughly 80 percent from its 2021 peak.

What happened next is the investable story. CEO Rasmus Errboe, who took over in 2024, executed a turnaround plan built on three levers: raise capital, sell non-core assets, and stop spending cash faster than the business generates it.

The results show through the numbers. Ørsted completed a rights issue that raised roughly 60 billion kroner and sold its European onshore business for $1.7 billion to Copenhagen Infrastructure Partners. Net interest-bearing debt fell from 68 billion kroner at the start of 2025 to 22 billion kroner by the end of the first half of 2026 — a 67 percent reduction. The leverage ratio, measured as FFO to adjusted net debt, improved from 15.6 to 44.6 over the same period.

More importantly, cash flow turned. Free cash flow was negative 9.9 billion kroner in the first half of 2025. In the first half of 2026, it flipped positive at 364 million kroner. Second-quarter free cash flow alone was 1.3 billion kroner, up from just 290 million a year earlier. Operating cash flow rose 17 percent year over year to 9.1 billion kroner in H1.

The operating engine itself is improving. Offshore business EBITDA, which drives the company, grew to 11.9 billion kroner in the first half of 2026 from 10.3 billion a year earlier. Production from offshore assets rose 23 percent to 11.2 terawatt-hours, helped by stronger wind speeds, higher availability rates, and earnings from the Hornsea 3 construction agreement in the UK — the world's largest offshore wind farm.

Ørsted maintains full-year 2026 guidance of core EBITDA above 28 billion kroner. Gross investments are expected at 50-55 billion kroner, down from the peak spending years that bled cash. The company is guiding toward an average return on capital employed of roughly 11 percent for 2026-2027, rising above 13 percent by 2028-2030. And management announced it will reinstate dividends beginning with the 2026 fiscal year, with the first payout expected in 2027 — a modest starting level that grows annually.

What's Still Risky

The turnaround is real, but it's early. Return on capital employed sat at just 3.1 percent for H1 2026 — a structural gap between where Ørsted is and where it needs to be. That number will take years of consistent cash generation to close.

The U.S. portfolio remains a live risk. Revolution Wind and Sunrise Wind received suspension orders from the Bureau of Ocean Energy Management in December 2025 but restarted activities following preliminary injunctions in January and February 2026. Ørsted has said it needs $9.4 billion to complete its two remaining U.S. offshore wind projects. The regulatory environment there could shift again.

Offshore wind as an industry faces headwinds beyond the tax ruling. Supply chain inflation, rising interest rates, and permitting delays have all compressed project economics. The UK tax decision adds another layer of cost uncertainty for future projects. Ørsted's construction pipeline of 8.1 gigawatts spans three continents, and not every project in that pipeline will come in on budget or on time.

Still, comparing the tax ruling to the company's actual financial trajectory puts things in perspective. A £48 million tax deduction that never materialized does not threaten a company that raised 60 billion kroner, cut debt by two-thirds, and flipped free cash flow positive in one year.

The Investment Read

Ørsted trades on the Nasdaq Copenhagen at a market capitalization around $34 billion. It is not a yield play — no dividend exists yet. It is not a growth story in the tech sense — offshore wind is a capital-intensive, regulated business with multi-year project cycles. What it is, if the first half of 2026 holds, is a turning-around cash generator with the world's largest installed offshore wind capacity of 10.2 gigawatts and a disciplined management team that has proven it can stop the bleeding.

The UK tax ruling is noise against that backdrop. It affects future UK project economics and could pressure the industry broadly, but Ørsted's own exposure is limited and its geographic footprint — Europe, Asia Pacific, and now cautiously resuming in the U.S. — means a single jurisdiction's tax treatment does not define the investment case.

What would change the picture is not a court ruling but the cash flow trajectory itself. If free cash flow stays positive and the ROCE gap closes toward the 11 percent target, the story strengthens. If impairments recur or the U.S. situation deteriorates further, the turnaround narrative cracks. Those are the variables to track — not whether a £48 million deduction lands in the right tax bracket.
