Stegra — the Swedish green-steel scale-up formerly trading as H2 Green Steel — spent the last two weeks of April moving from agreement in principle to signed principal agreements on the €1.4 billion financing round that the company first announced on April 14, 2026. Per the company’s own timeline, signing of principal agreements was scheduled for the end of April, with closing of the financing round during June 2026, subject to credit approvals, finalisation of documentation and customary regulatory conditions precedent.
The financing is led by a Wallenberg Investments-led consortium that includes Temasek and IMAS, and is supported by existing shareholders — including Altor, which becomes the second largest owner post-closing, alongside Hy24 and Just Climate. The headline use of proceeds is to complete construction of the flagship green-steel plant in Boden, including previously communicated scope expansions, the insourcing of selected infrastructure components, coverage of increased project costs, and the establishment of a financial buffer.
The New Board: Senior Swedish Industrialists Take Control
Beyond the cheque size, the most consequential element of the round is governance. Investors agreed in principle to nominate three figures who together amount to a Wallenberg-aligned senior industrialist line-up:
Håkan Buskhe, the senior industrialist at Wallenberg Investments and former CEO of Saab AB, joins the board — an appointment that signals deep operational discipline and a habit of running long-cycle, capital-intensive industrial programmes. Paal Weberg, Managing Partner at Altor and the firm’s representative on the cap table since the early days, takes a board seat reflecting Altor’s position as second largest owner. And on closing, Leif Johansson — former CEO of AB Volvo and former chair of AstraZeneca — is set to assume the role of Chair of the Board, succeeding Shaun Kingsbury, who served as adviser to the Wallenberg-led consortium during the round.
Read together, the names tell the story of how Sweden’s industrial establishment is now anchoring what was, until recently, primarily a venture-style scale-up. Buskhe and Johansson have spent careers running engineering- and supply-chain-heavy industrial groups; Weberg sits on top of the financial discipline. The implicit promise to lenders, suppliers and offtakers is that Stegra’s second act is being run by people who have actually delivered industrial programmes at scale.
Boden First, Then the International Funnel
The immediate priority is unambiguous: complete construction in Boden and ramp into commercial operation. After several slower months during the funding activities, Stegra has confirmed it will now ramp up construction, with the project timeline under review. The Boden facility is being built to produce near-zero-emissions flat steel using hydrogen-based direct reduction of iron, with major offtakers including European automotive and white-goods customers already contracted.
What matters for NorthSouth HQ readers is what sits in the international funnel behind Boden. Stegra has been explicit, going back to the H2 Green Steel-to-Stegra rebranding, that it is building a multi-asset green-steel platform with a "solid funnel of potential projects" outside Sweden — with locations under consideration including Portugal, Canada and Brazil. Of these, the Portuguese project is the most advanced: site selection has been made, land has been reserved near Sines, and the company has received notification on the substantial allocation of the power needed to operate a fully-electrified large-scale production facility.
Why Sines Still Matters
The Sines logic is structural, not opportunistic. The site brings together deepwater port access (with Atlantic export capability for both feedstock and finished product), a competitive renewable power profile (with continued Iberian build-out of solar and wind capacity), and a developing hydrogen ecosystem anchored by Galp’s 100 MW Plug Power-supplied electrolyser, MadoquaPower2X’s €2.8 billion green hydrogen and ammonia complex backed by Copenhagen Infrastructure Partners, and Repsol’s H2ALBA project. For a green-steel mill with multi-hundred-megawatt power and hydrogen demand, that ecosystem matters more than nominal land cost.
Stegra has not committed to a final investment decision on Sines, and the rebuilt board will need to demonstrate Boden delivery before greenlighting another multi-billion-euro capital programme. But the Iberian project remains in scope, the local value-chain partnerships continue to evolve, and the Wallenberg-era governance brings the kind of patience required to run a parallel international expansion.
What to Watch Next
Three near-term signals will tell readers whether the Boden-then-Sines sequencing is on track. First, formal closing of the financing round in June 2026 (subject to regulatory approval) and the actual ramping of Boden construction. Second, the cadence of Boden offtake announcements during 2026, which validate the green-steel premium that underpins Stegra’s entire investment thesis. Third — and this is the corridor signal — any movement on the Sines power allocation, the local value-chain partnerships, or the timing for a Sines FID.
For Portuguese policymakers and Iberian energy investors, the Wallenberg-era Stegra is less a single deal and more a barometer of whether Sweden’s industrial establishment is willing to bet long capital on Iberian green industry. The signals from the end-April board reshuffle suggest the answer is yes — provided Boden delivers.
