Voestalpine’s Green Furnace Takes Shape as Tariff Litigation and Deep-Pocketed Rival Cloud the Outlook

Voestalpine's €1.5B green steel project advances, but hydrogen gaps, U.S. tariff reinstatement, and rival Stegra's massive funding threaten its competitive edge. Aerospace orders offer a buffer.

The shell of Voestalpine’s first electric arc furnace is rising in Linz, but the Austrian steelmaker is finding that the cleanest steel plant in the world means little if the supply chain around it remains half-built. While the company’s construction schedule holds firm, the legal and competitive landscape is growing more hostile by the week. Shares closed Friday at €44.86, down 2.4% on the day, after having touched nearly €46 on Thursday. Over the past twelve months the stock has vaulted roughly 86% higher, though year-to-date the gain is a more contained 19%.

The €1.5 billion green steel project remains on track: mechanical assembly begins next year, and the first output from the new furnaces in Linz and Donawitz is expected by February 2027. Once fully operational, the two sites will produce about 2.5 million tonnes of CO?-reduced steel annually. Yet chief executive Herbert Eibensteiner struck a cautious tone this week, warning that the absence of reliable hydrogen networks and competitively priced renewable energy could cripple the economics of the new capacity. He is pressing European policymakers to extend the validity of CO? certificates beyond 2034, arguing that the industry needs more time to complete the infrastructure transition.

That infrastructure gap is not the only headache. A U.S. federal appeals court has reinstated the steel tariffs originally imposed under the Trump administration, overturning a previous suspension. The current U.S. administration plans to appeal to the Supreme Court, prolonging the legal limbo for European exporters. Switzerland is separately negotiating carve-outs with Washington. The ruling means that Voestalpine’s exports to America will continue to face the same punitive duties for the foreseeable future.

Meanwhile, competition in the green-steel race is intensifying. Swedish rival Stegra has raised €1.4 billion from investors since April and unlocked an additional €1.5 billion in credit lines in mid-May, assembling the war chest needed to build the world’s largest facility for fossil-free steel. The sheer scale of Stegra’s financing underscores the capital demands of the industry — and the urgency of securing long-term offtake agreements that could lock Voestalpine out of emerging green markets.

There are bright spots. Voestalpine’s High Performance Metals division booked aviation orders worth roughly €1 billion over the next five years, with Airbus among the customers for its forged components and specialty alloys. The sector is a key buffer against a weak European automotive market. In the nine months through December, group EBIT climbed almost 21% to €473 million, supported by rail infrastructure and aerospace demand. Last week, UBS upgraded U.S. rebar producer Commercial Metals, citing easing price pressure in American concrete steel — a trend that typically helps the global pricing environment and, by extension, Voestalpine’s own margin-rich specialties.

The company will release full-year results in early June, with analysts zeroing in on free cash flow — which turned positive in the third quarter — and the net debt-to-EBITDA ratio. If that ratio stays below 2.0, the new dividend policy will kick in: a payout of 30% of earnings per share, with a floor of €0.40. The formula gives income-oriented shareholders some visibility, but its activation depends entirely on the cash generation performance in the coming quarters. Next week’s U.S. Empire State Manufacturing Index and European consumer price data will provide the next factual checkpoint on how the broader industrial backdrop is shaping up.
