The improvement was mainly related to higher result in SSAB Europe and SSAB Americas. The shipments of advanced steels was at a good level in the first quarter and growth in these steels is a key in SSAB’s strategy to accelerate premium leadership. In 2025, the European Commission proposed new trade measures to protect the EU steelmaking sector against global overcapacity. In April, a political agreement was reached between the European Parliament and Council. In the next step, the proposal is examined and approved in parallel by the Parliament and the Council with the aim to ensure its entry into force on July 1, 2026. SSAB expects this to improve the supply-demand balance in the European market. SSAB continues to transform to a modern and fossil-free operation. The conversion of Oxelösund is progressing with the construction of the new electric arc furnace. The construction of the new and highly- efficient mini-mill in Luleå was paused at the beginning of the second quarter after contractors have reported symptoms and illness. SSAB is continuing sampling and testing in order to confirm or rule out possible causes, so that the site can be reopened safely. The regular steel production in Luleå is proceeding as normal. The direct effects on SSAB from the war in the Persian Gulf have been limited, but customers are becoming more cautious across several markets, and there is a risk that a prolonged conflict could negatively affect economic activity. Outlook for the second quarter of 2026 Outlook for the steel divisions Q2 2026 vs. Q1 2026 Shipments Realized prices SSAB Special Steels Stable Somewhat higher SSAB Europe Stable Somewhat higher SSAB Americas Stable Somewhat higher Definitions: Significantly lower (>10 %), Lower (5-10 %), Somewhat lower (0-5 %), Stable (~0 %), Somewhat higher (0-5 %), Higher (5-10 %), Significantly higher (>10 %) The costs of raw materials for SSAB Special Steels and SSAB Europe are expected to be somewhat higher compared to the first quarter of 2026, whereas for SSAB Americas, costs are expected to be fairly stable. Major planned maintenance outages 2026 The Group’s total maintenance costs for the full-year 2026 are expected to be SEK 1,450 (1,410) million, unchanged compared to the previous estimate. The table below shows the expected costs for 2026 and the actual costs during 2025. The figures include the impact of the direct maintenance cost and the cost of lower capacity utilization but exclude lower margins due to lower shipments.

Reg.no. 556016-3429 ===== SIDA 4 ===== SSAB Group – First quarter of 2026 The market during the first quarter Within the global market for high-strength steels, demand was seasonally higher compared with the previous quarter. The underlying demand in Europe showed some improvement. Markets in the Middle East were negatively affected by the war in the Persian Gulf. The European market for standard steels remained cautious during the first quarter, but with a seasonal improvement compared with the previous quarter. Inventory levels at distributors are assessed to be somewhat high. Import volumes declined, and some production capacity among European steel producers was idled during the quarter, partly due to maintenance. Market prices for strip and heavy plate increased during the first quarter, driven by expectations of more restrictive import measures into the European market. In the middle of April, a political agreement was reached between the European Parliament and Council on the measure to protect the EU steelmaking sector against global overcapacity. In the next step, the proposal is examined and approved in parallel by the Parliament and the Council with the aim to ensure its entry into force on July 1, 2026. In January 2026, the EU’s Carbon Border Adjustment Mechanism (CBAM) became fully operational with the goal of creating a more level playing field. The North American plate market was relatively strong during the first quarter and prices increased. Inventory levels among North American distributors are assessed to be somewhat low. Market prices in China for strip and heavy plate recorded some increase during the first quarter. Production and shipments SSAB’s production and shipments were higher compared to the first quarter of 2025. Production and shipments were also higher compared to the fourth quarter of 2025, which was impacted by planned maintenance outages. 2026 2025 2025 2025 Thousand tonnes Q1 Q1 Q4 Full-year Crude steel production 2,010 1,946 1,802 7,536 Rolling production 1,871 1,778 1,715 6,970 Steel shipments 1,736 1,676 1,515 6,364 Revenue and operating result Revenue for the first quarter of 2026 was SEK 25,336 (25,523) million, down 1% compared to the same period in 2025, mainly related to negative currency effects. Compared with the fourth quarter of 2025, revenue was up 15%, mainly due to higher shipments. EBITDA amounted to SEK 3,236 (2,369) million and the EBITDA margin was 13% (9%) for the first quarter of 2026. Operating result was SEK 2,201 (1,351) million. The increase compared to the first quarter of 2025 was primarily explained by improved result in SSAB Europe and SSAB Americas. Compared to the fourth quarter of 2025, operating result was up by SEK 1,445 million. The fourth quarter of 2025 was impacted by planned maintenance cost of SEK 1,020 million.

The conversion includes the closure of the existing blast furnaces and coke plant. At the same time, most operations in Oxelösund, including the advanced rolling mill and unique Q&T lines that produce high-strength steel will continue as before. The start of production is planned for early 2027, unchanged to previous assessment. SSAB’s transformation plan depends on the necessary infrastructure being in place on time, particularly regarding electricity supply, and there are currently pending appeals related to the power line to Oxelösund. Luleå The construction of the new and highly-efficient mini-mill in Luleå was paused at the beginning of the second quarter after contractors have reported symptoms and illness. SSAB is continuing sampling and testing in order to confirm or rule out possible causes, so that the site can be reopened safely. The production start of the new steel mill in Luleå is estimated to take place at the end of 2029. SSAB has flexibility for a robust implementation of the investment, taking into account financial capacity, customer demand and the market situation in general. During the first quarter, the investment in in Luleå was recognized as a strategic net‑zero project under the EU’s Net‑Zero Industry Act, confirming the project's importance for the EU’s future competitiveness and for the union’s ability to meet its climate and energy targets. Raahe The final stage of the Nordic transformation plan is the conversion of the Raahe steel mill in Finland, where the blast furnaces and coking plant is planned be replaced by electric arc furnaces, mirroring the approach in Oxelösund. The timing will depend on raw material availability, financial capacity, general market conditions, as well as the experience from the projects in Oxelösund and Luleå. Mobile The Investment in Mobile to increase the capacity for SSAB Special Steels’ products (Q&T) is on-going. The total investment amount is USD 74 million over three years. Production is assessed to start during 2027. Capital expenditure Capital expenditure amounted to SEK 1,909 (1,143) million during the first quarter of 2026. Strategic investments were SEK 1,488 (758) million. The increase relates primarily to the transformation of Luleå. The estimate for total maintenance and strategic capital expenditure for the full-year 2026 remains at SEK 13.5 billion. The corresponding sum of maintenance and strategic capital expenditure in 2025 was SEK 10.1 billion.

Coking coal is sourced from Australia, the USA and Canada, usually on annual supply contracts with monthly prices. SSAB’s mills in the USA use recycled steel material and source scrap metal on the spot market. The table below shows the fluctuations in SSAB’s purchase prices. The combination of lead times and contract terms for iron ore means that the results are affected with approximately a one-quarter delay, while coking coal has a lead time of around one and a half quarters. Scrap purchase prices have a lead time of around one month.

The lost time injury frequency per million hours worked (LTIF) was at all time low with 0.49 (0.67). Also, total recordable injury frequency (TRIF) decreased to all-time low at 5.4 (6.6). As earlier communicated, a fatal accident involving an employee of a subcontractor occurred at SSAB’s steel mill in Mobile, USA during the first quarter. SSAB is cooperating with authorities in the investigation of the incident, in accordance with standard procedures. Lost time injury frequency (LTIF) Direct CO2e emissions were somewhat higher compared with the first quarter 2025 due to higher production. Indirect emissions of CO2e decreased somewhat due to changed emission factors. Emissions per tonne were stable. SSAB aims to reduce carbon dioxide emissions by 48% until 2033, compared with 2018. Key actions include the transformation of the Nordic steel production using electric arc furnaces (EAF) and the production of decarbonized steel.

Revenue, EBITDA margin and operating margin Market trend The market remained cautious within the major customer segments during the first quarter, for example Construction and Automotive. Business segment comment The strategy to increase the share of premium products is yielding results and during the first quarter, deliveries of advanced steels reached record levels. Some of the advanced products previously exported from the Nordics to the United States within the Automotive customer segment have been reallocated to other markets as a result of the steel tariffs introduced in 2025.

Operating result increased to SEK 438 (33) million, compared with the same quarter in 2025. Higher shipments had a positive effect. Lower prices were more than compensated by lower cost for raw material. Operating cash flow amounted to SEK -397 (-1,758) million. The change was primarily due to smaller increase in working capital and a better result, compared to previous year. Capital expenditure during the first quarter was SEK 846 (371) million, of which SEK 683 (219) million were strategic investments mainly related to the new steel mill in Luleå. Development compared to Q4/25 Revenue increased by 21%. Higher shipments had a positive impact of 18 percentage points and higher prices contributed with 2 percentage points. Compared to the fourth quarter of 2025, operating result increased by SEK 323 million. Higher shipments and higher capacity utilization had a positive impact, partly offset by higher variable and fixed costs.

Operating result for the first quarter of 2026 was up SEK 37 million compared with the same period in 2025 and amounted to SEK 72 (35) million. Lower prices were more than compensated by lower inventory losses and measures to reduce costs. Operating cash flow during the first quarter of 2026 was SEK -82 (79) million. The decrease was mainly related to higher working capital, partly compensated by the result improvement. Capital expenditure during the first quarter was SEK 17 (33) million, of which SEK 0 (0) million were strategic investments. Development compared to Q4/25 Revenue was up 13% compared with the fourth quarter of 2025, primarily due to higher shipments.

Reg.no. 556016-3429 ===== SIDA 16 ===== Changes in the Group Executive Committee As previously communicated, Viktor Strömberg, EVP Strategy and Digitalization, took an additional role as interim CFO for Ruukki Construction from January 2026. He will continue as permanent CFO for Ruukki Construction and leave the Group Executive Committee. No successor will be appointed and the role of EVP Strategy and Digitalization will be discontinued from the Group Executive Committee. Tom Cox was appointed Head of SSAB Americas and a member of the SSAB Group Executive Committee during 2025, effective February 1, 2026. Risks and uncertainty factors SSAB benefits from having production facilities close to major customers both in Europe and the USA. However, the turbulence driven by trade barriers and tariffs, as well as the war in the Persian gulf has created uncertainty and represents a significant risk of lower economic activity. Similarly, there is increased regulatory uncertainty with the upcoming revision of the EU ETS system in 2026. Significant changes to the system could impact SSAB. The Swedish Financial Supervisory Authority (FI) is reviewing SSAB’s disclosure of the goodwill impairment of 2022 and has opened a sanction evaluation in the matter. If the FI finds that the disclosure was not reported in accordance with relevant guidelines, the FI may impose a sanction on SSAB, including an administrative fine, which may be material. SSAB has not made any provisions on the matter in its financial reporting. For more information regarding material risks and uncertainty factors, reference is made to the detailed description in the Annual Report 2025. Events after the end of the reporting period The construction of the new and highly-efficient mini-mill in Luleå was paused at the beginning of the second quarter after contractors have reported symptoms and illness. SSAB is continuing sampling and testing in order to confirm or rule out possible causes, so that the site can be reopened safely. The regular steel production in Luleå is proceeding as normal. In April, Tibnor’s acquisition of Ovako Metals Oy Ab received approval from the competition authorities. The transaction is expected to be completed in the coming weeks.

No material changes in accounting principles have taken place since the Annual Report for 2025. Swedish Financial Supervisory Authority (FI) review regarding disclosure of goodwill impairment As previously disclosed, the Council for Swedish Financial Reporting Supervision (The Council) questioned a part of the goodwill impairment of SEK 33.3 billion that SSAB reported in December 2022. Following a dialogue between SSAB and the Council during 2023 and 2024, the Council submitted the matter to FI. FI initiated a review regarding the disclosure around the goodwill impairment in March 2025. In September 2025, FI informed SSAB that it has opened a sanction evaluation in the matter. The review is still ongoing. SSAB maintains that the disclosure was reported in accordance with relevant guidelines, an assessment shared by the company’s auditors and other experts SSAB has consulted on the matter. Valuation of financial assets and liabilities Debt reported in the balance sheet as long-term interest-bearing liabilities (including the short-term part) amounted to SEK 8,434 million at March 31, 2026 while its fair value was SEK 8,467 million. Since the loans will be held until maturity, they are not reported at fair value.

Reg.no. 556016-3429 ===== SIDA 27 ===== Auditor’s review report Introduction We have reviewed the condensed interim report for SSAB AB as of 31 March 2026 and for the three months period then ended. The Board of Directors and the Managing Director are responsible for the preparation and presentation of this interim report in accordance with IAS 34 and the Swedish Annual Accounts Act. Our responsibility is to express a conclusion on this interim report based on our review. Scope of review We conducted our review in accordance with the International Standard on Review Engagements, ISRE 2410 Review of Interim Financial Statements Performed by the Independent Auditor of the Entity. A review consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing and other generally accepted auditing standards in Sweden. The procedures performed in a review do not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the interim report is not prepared, in all material respects, in accordance with IAS 34 and the Swedish Annual Accounts Act regarding the Group, and in accordance with the Swedish Annual Accounts Act regarding the Parent Company.
