Brazilian iron ore pellet producer Samarco Mineração S.A. (hereinafter referred to as Samarco) disclosed on its official website that the Momento 3 production resumption phase continues to advance, with the target of restoring 100% installed capacity from 2028. Based on Samarco's previously disclosed current 60% capacity corresponding to approximately 15 million mt/year of pellets and iron ore fines, the 100% installed capacity is approximately 25 million mt/year. The Ubu industrial complex will be a key component of this round of production resumptions. According to Samarco's official website, the Ubu industrial complex located in Anchieta, Espírito Santo State, Brazil, plans to invest approximately 3.5 billion reais (approximately $700 million), primarily for the modernisation and production resumption of two pellet plants. The Ubu industrial complex has four pellet plants in total; the current phase has restored two pellet plants to operation, and the next step towards full production includes restoring Ubu Pellet Plants 1 and 2, along with advancing the beneficiation and filtration systems at the Germano mine. The company previously disclosed that the project will drive local industrial investment and employment growth, and lay the foundation for the subsequent full restoration of pellet capacity. The company is continuously investing in pellet production system upgrades, tailings filtration facility construction, and low-carbonisation operations. Samarco primarily produces iron ore pellets and iron ore fines for the steel industry. The company halted production following the tailings dam accident in 2015 and began gradually resuming operations in 2020. The modernisation and production resumption of the two Ubu pellet plants will increase Brazil's seaborne pellet and iron ore fines supply.

ArcelorMittal (AM) — 2025 Annual Report Summary ArcelorMittal, the world's second-largest steel producer, released its 2025 Annual Report in March 2026. During the year, the Group's steelmaking operations experienced a broad-based slowdown: crude steel output in Europe contracted sharply by 6.6% year-on-year, while volumes in India and Brazil also declined. Only North America recorded output growth, driven by the consolidation of an additional steelworks. These dynamics reflect softening apparent steel consumption (ASC) globally, compounded by intensifying competitive pressures. Nonetheless, the Mining segment delivered an outstanding performance — iron ore shipments from Liberia surged 37.5%, providing a meaningful offset to the headwinds in the steelmaking divisions. I. 2025 Key Production, Shipment & Financial Overview In 2025, ArcelorMittal demonstrated strong operational resilience against the backdrop of subdued global steel demand and complex trade barriers. Portfolio optimisation — notably the full consolidation of the Calvert flat-rolled finishing facility — and robust growth in the iron ore business were the key highlights of the year. Despite a marginal decline in crude steel production and shipments, net profit expanded materially, primarily driven by non-recurring items — in particular, a US$1.9 billion accounting gain arising from the acquisition of the remaining 50% equity interest in AMNS Calvert. The increase in net debt was principally attributable to the full consolidation of Calvert and other M&A activities. II. Segment Distribution & Operational Performance In 2025, ArcelorMittal's global operational footprint underwent significant structural reconfiguration, most notably through the full acquisition of the North American Calvert flat-rolling facility and the divestiture of non-core assets in Bosnia-Herzegovina, further optimising the Group's production and shipment mix. The following presents a detailed comparison of key segment production and shipment data for 2025 versus the prior year: North America The segment recorded growth in both output and shipments in 2025, primarily benefiting from the full consolidation of the AMNS Calvert facility in the second half of the year, and the recovery of Mexican production following the 2024 labour strike. Crude Steel Production: 7.8 Mt (2024: 7.5 Mt), up 2.9% YoY Steel Shipments: 10.3 Mt (2024: 10.1 Mt), up 2.2% YoY Key Development: The 1.5 Mtpa Electric Arc Furnace (EAF) at the Calvert facility was commissioned in June 2025, enhancing the supply capability of high value-added flat products in the region. 2026 Volume Outlook: Both production and shipments are expected to increase in line with broader regional trends. Growth Driver: The 1.5 Mtpa EAF at Calvert, consolidated in H2 2025, is currently in capacity ramp-up phase and will contribute incremental volumes in 2026. Brazil Despite margin pressure, the Brazil segment maintained highly stable production and shipment volumes, continuing to serve as a key profitability pillar for the Group. Crude Steel Production: 14.3 Mt (2024: 14.5 Mt), down 1.3% YoY Steel Shipments: 13.9 Mt (2024: 14.1 Mt), down 0.9% YoY Key Development: The Barra Mansa long products mill expansion was commissioned in H2 2025, adding 0.4 Mtpa of high value-added long steel capacity. 2026 Volume Outlook: Steel shipments are projected to reach 15.4 Mt in 2026, significantly above the 13.95 Mt recorded in 2025. Growth Driver: Despite demand headwinds in 2025 caused by elevated interest rates and a surge in Chinese imports, the Group holds an optimistic outlook for 2026 growth. Europe Affected by soft market demand and a planned major reline of Blast Furnace No. 4 at Dunkirk, European crude steel output contracted. However, the smaller decline in shipments indicates relatively resilient market penetration. Crude Steel Production: 29.2 Mt (2024: 31.2 Mt), down 6.6% YoY Steel Shipments: 28.4 Mt (2024: 28.7 Mt), down 0.9% YoY Key Development: The divestiture of the Zenica long products integrated steelworks in Bosnia-Herzegovina was completed in October, reflecting the Group's strategic transition toward lower-carbon assets. 2026 Volume Outlook: Shipments are expected to recover and grow. Growth Driver: As the EU Carbon Border Adjustment Mechanism (CBAM) and the revised Tariff Rate Quota (TRQ) regime progressively take effect in 2026, the Group anticipates European domestic steelmakers recapturing market share from import competition. India & Other Joint Ventures Focus on the strategic joint venture AMNS India (60% equity interest): Crude Steel Production: 7.2 Mt (2024: 7.5 Mt), down 4.5% YoY, impacted by market volatility in H1 and unplanned maintenance outages Steel Shipments: 7.9 Mt (2024: 7.9 Mt), shipments remained resilient Key Development: The Hazira integrated steelworks in India is being expanded to 15 Mtpa capacity. The Group has also announced a long-term greenfield project in Andhra Pradesh with an 8.2 Mtpa capacity target, with the objective of increasing hot-rolled coil (HRC) capacity to 15 Mtpa by H2 2026, providing incremental production and shipment uplift. Crude Steel Production (Other Subsidiaries): 4.3 Mt (2024: 4.6 Mt), down 6.52% YoY Mining The Mining segment was the Group's strongest growth engine in 2025, driven by the successful ramp-up of the Phase II expansion project in Liberia. Own Iron Ore Production (Mining segment only): 35.3 Mt (2024: 27.9 Mt), up 26.5% YoY Iron Ore Shipments: 36.3 Mt (2024: 26.4 Mt), up 37.5% YoY Key Development: Liberia achieved a record annual shipment of 10 Mt and is progressing steadily toward a 20 Mtpa production target. 2026 Mining Segment Outlook: Liberia (AML): Volume Target: 20 Mtpa shipment target. The Group specifically projects that by end-2026, as the Phase II expansion and the beneficiation plant continue to ramp up, annualised shipments will exceed 18 Mtpa (vs. 10 Mt in 2025). Key Progress: A blended production model combining sinter fines and concentrates from Phase II will support a significant increase in production and shipment volumes, with rail haulage capacity being expanded toward a 30 Mtpa annual throughput target. Canada (AMMC): Trend: Stable production maintained. The conversion of the high-grade iron ore pellet plant for Direct Reduced Iron (DRI) production is expected to be completed in Q2 2026. 2026 Production & Shipment Outlook Summary The 2025 production and shipment profile signals ArcelorMittal's strategic pivot toward quality over pure volume. Despite marginal fluctuations in crude steel output in Europe and Brazil, the growth from high value-added assets in North America and low-cost iron ore operations in Liberia is structurally rebuilding the Group's cost and margin base. The Group projects global apparent steel consumption (ASC) ex-China to grow by 2% in 2026. Against this macro backdrop, the Group forecasts an increase in steel production and shipments across all regions in 2026 compared to 2025, underpinned by improvements in operational efficiency and the positive impact of trade protection measures. III. Production Infrastructure & Process Technology Profile ArcelorMittal operates a highly diversified asset portfolio spanning the full upstream-to-downstream value chain — from iron ore mining to downstream finishing and processing. As of end-2025, the Group's production process structure is as follows: Process Mix: Basic Oxygen Furnace (BOF) output accounts for 74% (41.2 Mt); Electric Arc Furnace (EAF) accounts for 26% (14.4 Mt). Facility Scale: The Group currently operates 30 Blast Furnaces (BF) and 27 Electric Arc Furnaces (EAF) . Capacity Distribution: Europe remains the largest production base, with an annual crude steel capacity of 39.5 Mt (53% of total), followed by Brazil (16.4 Mt) and North America (12.5 Mt). IV. Raw Material Self-Sufficiency & Supply Chain Integration The Group maintains a high degree of vertical integration upstream and downstream to hedge against market volatility — a core pillar of its industrial competitive advantage: Iron Ore Supply: Own iron ore production grew 15.1% YoY to 48.8 Mt in 2025. Canada (AMMC) contributed 25.6 Mt, while Liberia (AML) surged to 9.7 Mt. Self-Sufficiency Rates: In 2025, the Group achieved an iron ore self-sufficiency rate of 72% , a coking coal self-sufficiency rate of 91% , and a scrap steel and Direct Reduced Iron (DRI) self-sufficiency rate of 55% . Logistics Capacity: The Group operates 18 deep-water port facilities and associated rail infrastructure, handling over 51 Mt of freight annually. V. Key Asset Restructuring & Industrial Portfolio Realignment 2025 was a year of deep portfolio optimisation for the Group — divesting weaker assets and concentrating resources in high-growth, high value-added operations. Full Consolidation of Calvert (USA): In June 2025, the Group completed the acquisition of the remaining 50% equity interest in AMNS Calvert (previously a joint venture with Nippon Steel Corporation) at a nominal consideration. The facility is the most advanced flat-rolled steel finishing complex in North America. The newly constructed 1.5 Mtpa EAF produced its first slab in June 2025. Asset Divestitures & Operational Rationalisation: Bosnia-Herzegovina: Completed the sale of the Zenica integrated steelworks and the Prijedor iron ore mine. South Africa: Rationalisation of the long products business and the idling of the Newcastle steelworks were completed by end of January 2026. India Expansion: AMNS India remains a core growth engine. The Hazira integrated steelworks is on track to expand capacity to 15 Mtpa by H2 2026. VI. Major Capital Project Progress (Capex Allocation) ArcelorMittal is currently in a dual capital expenditure cycle: EAF transition and upstream iron ore capacity expansion . Total capital expenditure in 2025 amounted to US$4.34 billion . VII. Decarbonisation Pathway & Industrial Technology Upgrade ArcelorMittal is at a critical juncture in its transition from conventional blast furnace-based integrated steelmaking toward low-carbon process routes: EAF Capacity Expansion: By end-2026, the Group expects to add 3.4 Mtpa of EAF capacity, spanning Gijón and Sestao in Spain, and Calvert in the USA. Key Technology Projects: The 2.0 Mtpa EAF project at Dunkirk, France (€1.3 billion investment) is planned for commissioning in 2029 and is expected to generate carbon emissions at approximately one-third of the level of a conventional blast furnace. Energy Transition: By end-2025, the Group had commissioned 1.6 GW of renewable energy equity capacity, with a further 1.2 GW under construction, primarily in India and South America, with the objective of supplying low-cost clean electricity to steelmaking operations. Carbon Footprint: Absolute carbon emissions declined 3.1% YoY in 2025, representing a cumulative reduction of 47% from the 2018 baseline. It is noteworthy that, given the limited commercial-scale deployment of low-carbon technologies (green hydrogen, Carbon Capture and Storage), the Group's emissions reductions are currently achieved primarily through portfolio restructuring and EAF electrification . VIII. Additional Key Information Portfolio Optimisation: Full Acquisition of Calvert: By acquiring NSC's 50% equity stake, ArcelorMittal has gained full operational control of North America's most advanced flat-rolled steel finishing complex. Exit from Non-Core Assets: The divestiture of the high-carbon-intensity integrated steelworks at Zenica, Bosnia-Herzegovina, and associated iron ore mines reflects a "decarbonise first, then grow" portfolio strategy. Operational Risks: Geopolitical Risk: The Kryvyi Rih steelworks in Ukraine (AMKR) is currently operating at only 35% of rated capacity , facing significant logistics and supply chain disruption. Trade Barriers: US Section 232 tariffs were raised to 50% in 2025, increasing the cost burden on cross-regional material flows. 2026 Outlook: Global apparent steel consumption (ASC) ex-China is projected to grow 2% . The Group's capital expenditure plan for 2026 is budgeted in the range of US$4.5–5.0 billion , with continued focus on the Liberia iron ore expansion and the electrification of process technology in Europe. Summary: 2025 was a year of "deepening asset quality" for ArcelorMittal. By converting its core North American joint venture Calvert into a wholly-owned subsidiary, and achieving successful delivery milestones at the Liberia iron ore mine and India's green energy projects, the Group further consolidated its vertically integrated competitive advantages. For investors, the sustainability of free cash flow generation and the recovery of market share under the EU CBAM framework remain the key monitoring indicators over the next one to two years.

[SMM Global Steel Enterprise Special Report] A Detailed Analysis of US "Steel King" Nucor: 100% Electric Arc Furnace Forging High Profits, Vertical Integration Mitigating Cost Fluctuations Nucor Corporation is a company incorporated in Delaware in 1958. The company and its subsidiaries are engaged in the manufacture of steel and steel products. It also produces and procures ferrous and non-ferrous metal materials, primarily for use in its steelmaking operations. Most of its operating facilities and clients are located in North America. Its operations include international trading and sales companies responsible for buying and selling steel and steel products manufactured by the company and others. Nucor is also the largest recycler in North America, using steel scrap as the primary raw material for producing steel and steel products. In 2025, it recycled approximately 20 million gross tons of steel scrap. Operating Performance Data source: Nucor Corporation Annual Report、SMM Reasons behind the performance changes: ① Decline in gross profit: The primary reason for the decline in gross profit in 2025 was the compression of profit margins in the steel products segment. Due to lower average selling prices, gross profits from the grating and decking, building systems, and rebar fabrication businesses under this segment all experienced significant declines. ② Steel mill segment growth: In contrast, gross profit in the steel mill segment increased, primarily driven by higher sales and improved steel industry spreads. ③ Investment expenditures: Over the past three years, Nucor invested approximately $9.73 billion in capital expenditures and acquisitions, aiming to expand its product portfolio and enhance operational flexibility. Segments, Major Products, and Marketing Nucor reports its results in three segments: the steel mills segment, the steel products segment, and the raw materials segment. The steel mills segment is Nucor's largest segment, accounting for 62% of the company's sales to external clients for the fiscal year ended 2025. It primarily sells its products to steel service centers, manufacturers, and fabricating enterprises located in the US, Canada, and Mexico. In 2025, the steel mills segment sold approximately 19,848 kt of products to external clients. Data source: Nucor Corporation Annual Report、SMM The Steel Products segment primarily produces high-value-added downstream construction and industrial components, holding leading positions across the U.S. in multiple sub-segments including steel joists, prefabricated metal buildings, and insulated metal panels. It accounted for 29% of the Company's net sales to external clients for the year ended 2025. In 2025, total sales of major products in the Steel Products segment were approximately 1.478 million mt, including approximately 658,000 mt of steel joists and joist girders, approximately 436,000 mt of steel deck, and approximately 384,000 mt of metal building systems. Although physical sales volume (tonnage) was far below that of the Steel Mills segment, the per-mt selling price and profit margin were much higher than those of basic steel, and the segment also ranked first in market share across the U.S. in multiple areas. Data source: Nucor Corporation Annual Report、SMM The Raw Materials segment is the cornerstone of Nucor's vertical integration strategy, primarily operated through its wholly-owned subsidiary The David J. Joseph Company (DJJ), and manages DRI production facilities in Louisiana and Trinidad. By blending DRI with steel scrap, it supports electric arc furnace (EAF) production of higher-grade sheets & plates while ensuring cost advantages and supply security of raw materials. It accounted for 9% of the Company's net sales to external clients for the year ended 2025. In 2025, approximately 20 million gross tons of steel scrap were recycled and processed. Data source: Nucor Corporation Annual Report、SMM Clients and Markets Data source: Nucor Corporation Annual Report、SMM Major Development Projects in Recent Years The vast majority (91%) of Nucor's capital was allocated to internal construction (CapEx), strengthening core competitiveness through technology upgrades (such as electric arc furnaces and micro mills); a small portion was used for strategic acquisitions to achieve "outward expansion" into high-margin downstream areas. Through acquisitions such as SWDP, the company quickly entered high-barrier, high-growth sub-segments including data centers and green energy, making its business structure more resilient to cyclical downturns. Data source: Nucor Corporation Annual Report、SMM Core Logic of Vertical Integration for Cost Reduction: Raw Material Supply Structure Data source: Nucor Corporation Annual Report、SMM Core Risk Factors The greatest risk facing Nucor is a combination of internal and external challenges — internally, cost fluctuations in steel scrap and energy; externally, the impact of low-priced imported steel resulting from global (especially China's) overcapacity. Specifically: 1. Core Industry Risks ① Severe global supply-demand imbalance: Global steel surplus capacity reached 704 million net mt in 2025 (8 times US annual production). It is expected to further increase to 795 million mt by 2027. ② Regional impact: China's annual production has exceeded 1 billion mt in each of the past 8 years, and Chinese steelmakers continue to invest in new capacity in Southeast Asia and Africa. ② Import shock: This surplus leads to a flood of low-priced steel into the US market, creating significant downward pressure on Nucor's product prices, sales, and profit margins. 2. Production Cost Risks ① Steel scrap price sensitivity: Nucor uses 100% electric arc furnaces (EAF), with steel scrap being the largest cost item. Steel scrap prices fluctuate significantly and are beyond Nucor's control. ② Supply chain uncertainty: Although Nucor has achieved a degree of self-sufficiency through its DRI plants and DJJ recycling system, pig iron and iron ore pellets still rely on international procurement, facing geopolitical risks (e.g., Ukraine, Russia, Brazil). 3. Operational Challenges ① Energy-intensive nature: Steelmaking relies on large amounts of electricity (for melting) and natural gas (for heating and DRI production). ② Cost pass-through: Energy prices are affected by demand, the regulatory environment, and transmission infrastructure (pipelines/power grid), and cost surges may erode profits. 4. Compliance and ESG Risks ① Emission reduction pressure: The steel industry faces intense scrutiny due to greenhouse gas (GHG) emissions. ② Policy risk: Although Nucor's emission intensity is far lower than its blast furnace peers, increasingly stringent environmental protection laws and regulations may increase capital expenditures or restrict operations at existing facilities. 5. End-Use Market Risks ① Industry cyclicality: The steel industry is highly correlated with the macro economy. ② End-use market fluctuations: Nucor's largest market is non-residential construction. If this sector (e.g., commercial offices, industrial facilities) contracts due to high interest rates or economic recession, it will directly impact Nucor's performance severely.

Strategic Resources Inc. announced on March 12, 2026, the acceleration of its BlackRock Project in Quebec to address global pellet scarcity. Phase 1 of the project is designed to deliver 4 million tonnes per year of high-purity iron ore pellets. The project is currently in the provincial environmental authorization phase and targets North American and European steelmakers.

On February 10, 2026, Swedish mining giant LKAB reported that its iron ore pellet production rose by 14% year-on-year in the final quarter of 2025. The company continues to prioritize high-grade, carbon-efficient pellets for the European market. This increase comes as SSAB’s fossil-free steel project in Luleå was officially recognized as a "strategic zero-emission project," further integrating the Swedish mining-to-steel value chain.

【SMM Steel】UK-based company Binding Solutions has reached an agreement with Mitsui Iron Ore Development to produce low-carbon iron ore pellets in Western Australia's Pilbara region. The company's technology significantly reduces energy consumption and CO2 emissions compared to conventional pellet production processes. The partnership will utilize a low-energy cold agglomeration process to transform lower-grade iron ore fines into higher-value pellets. These pellets are suitable for electric arc furnace steelmaking, supporting steelmakers' decarbonization efforts. Binding Solutions has previously conducted industrial trials with producers such as British Steel and aims to build an industrial-scale production plant.
