Luxembourg, February 5, 2026 - ArcelorMittal (referred to as "ArcelorMittal" or the "Company" or the "Group") (MT (New York, Amsterdam, Paris, Luxembourg), MTS (Madrid)), the world's leading integrated steel and mining company, today announced results¹ for the three-month and twelve-month periods ended December 31, 2025

4Q 2025 key highlights:

Safety focus is driving improved performance: Protecting employee health and safety is a core Company value. Progress is evident across all key safety KPIs, including a significant improvement in fatality prevention. The Company is now entering the second year of its three‑year safety transformation program, moving into the implementation and scale‑up phase and embedding the foundations for a consistent ‘one safety culture' across the Group

Strategy is delivering structurally improved margins: Despite facing significant headwinds in 2025, the Company delivered a resilient performance with EBITDA of $6.5bn, supported by $0.7bn from strategic growth investments. This included record Liberia iron ore shipments and the ongoing expansion of renewables capacity in India. EBITDA per tonne rose to $121, more than double previous cycle lows, reflecting continued asset optimization, diversified market exposure, and the benefits of the strategic investment program. FY 2025 net income was $3.2bn and basic EPS $4.13/sh (adjusted net income of $2.9bn and EPS $3.85/sh)⁴

Business continues to generate significant cash flow for investment and returns: Over the past 12 months, the Company generated $1.9bn in investable cash flow⁶(net cash provided by operating activities less maintenance/normative capex), broadly in line with $2.0bn generated in FY 2024. In 2025, the Company invested $1.1bn in strategic capex to build long‑term EBITDA capacity, returned $0.7bn to shareholders, and allocated $0.2bn to M&A

A solid investment grade balance sheet is our strategic foundation: In 2025, both Moody's (Baa2, stable outlook) and S&P (BBB, stable outlook) upgraded ArcelorMittal's credit ratings, reflecting the stronger credit profile, consistent cash generation and improved resilience. Year-end net debt was $7.9bn (gross debt of $13.4bn and cash and cash equivalents of $5.5bn) with total liquidity of $11.0bn⁷

Capital return policy is creating significant value for shareholders: Reflecting the continued structural improvement in earnings, the Board proposes to increase the annual base dividend to shareholders to $0.60/sh in FY 2026 (from $0.55/sh in FY 2025), to be paid in four equal quarterly installments starting March 2026.

The Company will continue to return a minimum of 50% of post-dividend free cash flow to shareholders via share buybacks. In 2025, the Company repurchased 8.8m shares for $262m, bringing the total reduction in the fully diluted share count to 38% since September 2020⁵

Strategic priorities

A balanced and fair European steel market: CBAM, together with the new tariff-rate quota (TRQ) trade tool structurally resets the outlook for the European steel industry. Lower imports will lead to higher capacity utilization, restoring profitability and returns on capital to healthy, sustainable levels. ArcelorMittal is well positioned to meet the anticipated increase in domestic demand with high-quality European steel delivered with premium service levels

Harness the economic opportunities of the energy transition to create shareholder value: Steel is central to the global energy transition, and ArcelorMittal is positioning its portfolio to capture the best opportunities across the value chain. This includes building high-quality renewable energy with a clear pipeline to 2.8GW capacity by end 2028, expanding capability to meet rising demand for low carbon-intensity steels with 3.4Mt new EAF capacity, and growing automotive electrical steels capacity to 0.4Mt NOES by end of 2028. These investments will continue to support a higher‑quality, higher‑margin earnings profile for the Group

Strategic growth delivery: The Group's strong financial position (supported by a positive free cash flow outlook for 2026 and beyond) continues to enable disciplined organic investment aimed at strengthening future profitability and cash generation

In 2025, EBITDA benefited from key strategic projects, including the Vega CMC expansion in Brazil (completed in 2024), the 1GW renewables project in India, Liberia iron ore capacity expansion, and contributions from recent M&A including the 100% consolidation of Calvert in the US (from June 2025)
Recently completed and ongoing projects are expected to add a further $1.6bn of EBITDA potential ($0.7bn in 2026 and $0.9bn from 2027 onward). Growth in 2026 will be supported by: start-up of the 4.5Mtpa DRI-quality pellet feed plant at Serra Azul (Brazil); ramp up of the new 400kt sections and bar mill in Barra Mansa (Brazil); continued progress towards 20Mtpa iron ore capacity in Liberia (expected to be completed by the end of 2026); and ongoing ramp‑up of the 1.5Mtpa EAF in Calvert toward full utilization, and the full impacts of recently completed M&A
From 2027 onward, further potential uplift is expected to come from: the AMNS India expansion to 15Mtpa (2H 2026); the Las Truchas (Mexico) concentrate capacity increase and Mardyck (France) electrical steels project, both expected to start up in 1H 2027; the non-grain oriented electrical steel (NOES) facility in the US (2H 2027) and the completion of the new 1GW India renewables program in 2028

Outlook

Demand expected to increase in 2026: The Company expects world ex-China apparent steel demand to grow by +2% in FY 2026. The Company forecasts steel production and shipments to increase across all regions in 2026 versus 2025, supported by operational improvements and the impact of trade protections. In Europe in particular, ArcelorMittal is expecting to benefit as domestic mills progressively regain market share from imports with the combined effect of CBAM and the new TRQ mechanism strengthening through the year

Capex in support of growth: ArcelorMittal's global asset base positions the Company to capture medium‑ and long‑term growth in steel demand, driven by investments in the energy transition, new infrastructure and mobility systems, defence security and data‑center capacity. The Company's capex in 2026 is projected to be within the range of $4.5-$5.0bn

Commenting, Aditya Mittal, ArcelorMittal Chief Executive Officer, said:

"2025 was a pivotal year for the global steel industry and ArcelorMittal. While the ongoing geopolitical volatility brought significant challenges, important foundations were also laid for a more supportive operating environment moving forwards.

On safety, there is a visible improvement in our results, reflecting the foundations for change we have embedded across all operations. Through consistent and tangible actions, we are fundamentally transforming our approach to health and safety globally.

The global economy has seen a shift towards greater domestic supply resilience, including the introduction of widespread tariffs. This led to an increasing number of countries finally taking steps to address the competitiveness of their manufacturing industries. Nowhere was this more necessary than in Europe, where ArcelorMittal has significant, high-quality operations. One of the most important developments was the proposal for new trade measures in Europe and the enhancements to the CBAM, to level the playing field on carbon costs. Combined, this will enable European producers to recover to sustainable utilization levels, and generate healthy returns on capital. And while the full benefits of the changes in the regulatory environment will emerge over time - more visibly in the second half and into 2027 - we are very well positioned to benefit from this direction.

Globally the outlook is also more favorable, including in India where we are growing our presence and enhancing our product offering. With $0.7bn of additional EBITDA generated already from strategic growth projects in 2025, a further $1.6bn is anticipated in the coming years as other projects are commissioned. We are also uniquely exposed to emerging macro growth drivers such as the energy transition, defence, data centers and infrastructure. Overall, this combination of positive regulatory developments, structurally supportive macro trends and an improved operating environment leave us well placed to continue delivering on our long-term commitment to achieve consistent returns for shareholders."

Safety and sustainable development

Health and safety:

Protecting employee health and safety is a core value of the Company. Progress is evident across all key safety KPIs, including a significant improvement in fatality prevention and an improvement in the LTIF rate to 0.65x in 2025 (compared with 0.70x in 2024).

The Company has completed the first year of its three‑year safety transformation program, supporting ArcelorMittal's journey toward zero fatalities and zero serious injuries. Key highlights from 2025 include:

Governance and safety leadership strengthened through an enhanced assurance model and completion of new safety leadership training, strengthening the ‘one safety culture' across the Group
Operational and process safety advanced supported by clearer risk-management guidance and the launch of the new Process Safety Management framework, including 12 global pilot sites
Safety embedded across processes, including updated HR practices such as H&S competences for leaders model

In 2026, safety transformation moves into the implementation and scale‑up phase. This stage focuses on embedding the foundations needed to establish a consistent ‘one safety culture' across the Group. Roadmaps have now been established at both the Corporate and site level to guide this work. These roadmaps are designed to drive consistency, strengthen discipline, and deliver measurable results as the core elements of our safety approach are integrated into everyday operations.

Sustainable development highlights:

The EU Commission's proposed TRQ trade tool sets import quotas at close to 50% of 2024 levels. It is estimated that this can reduce imports of flat and long products by ~10Mt, which would support higher domestic capacity utilization and restore profitability and ROCE to healthy, sustainable levels.

ArcelorMittal has the capacity to meet anticipated market demand. Existing furnaces can operate at higher utilization rates, while idled units can be brought back online as demand recovers. In addition, new capacity is expected to come online in 2026 with the start-up of the 1Mt Gijon EAF for long products and the expansion of the Sestao EAF to increase flat-steel output.

The energy transition continues to present an attractive opportunity for ArcelorMittal, enabling the Group and its customers to decarbonize through investments in renewables, electrical steels for EVs, and low-carbon building solutions.

In December 2025, the Company announced three new renewable energy projects in India totaling 1GW of solar and wind capacity, projected to deliver $0.2 billion annual non-cyclical EBITDA for the Group. Once completed, these projects will double ArcelorMittal's renewable energy capacity in India
ArcelorMittal announced in December 2025 that commissioning is underway on the annealing and varnishing lines (ACL) at its new electrical steels facilities in Mardyck, France. This development represents a key milestone in the Company's plan to expand electrical steels production capacity across Europe and the US, positioning ArcelorMittal to capture high-margin demand from the electrification of the automotive sector. Completion of the reversing mill ("REV") and annealing and pickling line ("APL") is expected in 2027.

Analysis of results for the twelve months ended December 31, 2025 versus results for the twelve months ended December 31, 2024

Sales for 12M 2025 decreased by 1.7% to $61.4 billion as compared with $62.4 billion for 12M 2024, primarily driven by a 2.3% reduction in average steel selling prices.

Operating income for 12M 2025 of $3.6 billion was 9.6% higher as compared to $3.3 billion in 12M 2024, primarily reflecting a positive year-on-year impact of $1.0 billion from exceptional items and impairments (a $0.7 billion benefit in 12M 2025 versus a $0.3 billion negative impact in 12M 2024), partly offset by lower EBITDA and higher depreciation.

EBITDA decreased by 7.3% to $6,541 million in 12M 2025 as compared to $7,053 million in 12M 2024. The decline was primarily driven by weaker results in North America (impacted by Section 232 tariffs and maintenance in Mexico), and lower contributions from India and JVs and Brazil segments due to weaker prices. These impacts were partly offset by improved performance in Europe, supported by a positive price-cost effect, and contributions from project ramp-ups, notably India renewables and Liberia Phase 2.

Depreciation cost for 12M 2025 of $2.9 billion was higher as compared to $2.6 billion in 12M 2024 primarily reflecting the capitalization of new assets coming online including Liberia iron ore, India (renewables), and the Vega and Serra Azul expansions in Brazil. 12M 2026 depreciation is estimated at approximately $3.0 billion.

Interest costs for 12M 2025 were $296 million, up from $110 million in 12M 2024, primarily due to higher average gross debt levels and lower interest income.

Foreign exchange and other net financing charges were $413 million in 12M 2025 as compared to $981 million in 12M 2024. The 12M 2025 result includes non-recurring cost of $0.1 billion related to the extension of the mandatory convertible bond¹¹, and reflects a $256 million foreign exchange gain (primarily driven by the depreciation of the US dollar against the euro and the Brazilian real), as compared to a $565 million loss in 12M 2024 (impacted by hyperinflation in Argentina and the appreciation of the US dollar against major currencies).

Current tax expense was $0.6 billion in 12M 2025, down from $1.0 billion in 12M 2024, reflecting lower proportion of earnings generated in high‑tax jurisdictions, such as Canada.

Net income increased to $3,152 million (EPS of $4.13/sh) in 12M 2025, up from $1,339 million ($1.70/sh) in 12M 2024. Adjusted net income was $2,938 million (adjusted EPS of $3.85/sh⁴) versus $2,326 million ($2.95/sh) in 12M 2024. The year-on-year increase in adjusted net income primarily reflects lower foreign exchange and other net financing charges and reduced tax expense, partially offset by lower EBITDA and higher interest costs.

Net cash provided by operating activities was $4.8 billion in 12M 2025 (including a $0.5 billion working capital release) as compared to $4.9 billion in 12M 2024 (including a working capital release of $0.1 billion). Capex totalled $4.3 billion in 12M 2025 (including $1.1 billion on strategic growth projects) as compared to $4.4 billion for 12M 2024 (including $1.3 billion on strategic growth projects). The Company generated free cash flow of $0.4 billion in 12M 2025 (versus $0.3 billion in the prior year). Following shareholder returns of $0.7 billion and M&A of $1.9 billion ($0.2 billion in cash plus debt consolidated), net debt increased to $7.9 billion as at December 31, 2025, as compared to $5.1 billion as at December 31, 2024.

Analysis of results for 4Q 2025 versus 3Q 2025

Sales decreased by 4.4% to $15.0 billion in 4Q 2025 as compared to $15.7 billion in 3Q 2025 primarily due to lower shipments.

Depreciation cost for 4Q 2025 was $856 million, higher than $736 million in 3Q 2025, primarily due to new assets in operation and certain assets reaching end of life.

Operating income of $0.3 billion in 4Q 2025 includes exceptional charges of $194 million which reflect $133 million of restructuring costs in Europe and a $61 million final non-cash charge on the sale of ArcelorMittal Zenica and Prijedor (Bosnia). This compares to operating income of $0.5 billion in 3Q 2025 which included $97 million in exceptional charges related to the purchase price adjustment for the acquisition of Nippon Steel's 50% stake in AM/NS Calvert.

EBITDA in 4Q 2025 of $1,593 million was 5.6% higher as compared to $1,508 million in 3Q 2025, primarily driven by higher results in the Mining segment, as well as improved results in the India and JV segment, partly offset by the North America segment.

Foreign exchange and other net financial charges of $450 million in 4Q 2025 were higher than the $86 million recorded in 3Q 2025, primarily reflecting higher foreign exchange charges ($120 million loss in 4Q 2025 versus $21 million gain in 3Q 2025) and non-recurring cost of $0.1 billion related to the extension of the mandatory convertible bond¹¹.

Net income of $177 million in 4Q 2025 (EPS of $0.23/sh) compares to net income of $377 million ($0.50/sh) in 3Q 2025. Adjusted net income was $654 million ($0.86/sh) in 4Q 2025 versus $474 million ($0.62/sh⁴) in 3Q 2025.

Net cash provided by operating activities during 4Q 2025 amounted to $3.0 billion and includes a $2.4 billion release of working capital. Capex totalled $1.2 billion for 4Q 2025 (including $0.3 billion spent on strategic projects), resulting in free cash flow of $1.7 billion. Net debt declined to $7.9 billion as of December 31, 2025, as compared to $9.1 billion on September 30, 2025.

Note: Mining segment comprises iron ore operations of ArcelorMittal Mines Canada (AMMC) and ArcelorMittal Liberia.

Sales in 4Q 2025 increased by 24.0% to $908 million as compared to $732 million in 3Q 2025, primarily due to 22.7% higher iron ore shipments, and a 3.5% increase in iron ore reference prices.

Iron ore production increased to 10.1Mt in 4Q 2025 as compared to 8.5Mt in 3Q 2025. During 4Q 2025 and 12M 2025, Liberia achieved record iron ore production and shipments, supported by operational improvements and the ongoing ramp-up of the Phase 2 capacity expansion. Liberia delivered 10Mt of iron ore shipments and generated $0.2 billion in EBITDA in 12M 2025. The operation is now progressing toward 20Mt annual capacity, with shipments expected to exceed 18Mt by end‑2026 as sinter‑feed output rises and the concentrator continues to ramp up, supporting improved price realization.

Operating income in 4Q 2025 increased to $198 million as compared to $142 million in 3Q 2025, driven by higher iron ore shipments, higher iron ore reference prices and lower costs.

As a result, EBITDA in 4Q 2025 of $314 million was 50.2% higher as compared to $209 million in 3Q 2025.

India and JVs

Income from associates, joint ventures and other investments increased to $206 million in 4Q 2025, as compared to $131 million in 3Q 2025, reflecting improved performance from various investees. Income from associates, joint ventures and other investments was lower in FY 2025 at $635 million, as compared to $779 million in FY 2024, reflecting lower earnings from AMNS India offset in part by incremental contribution from Vallourec which was acquired in August 2024.

ArcelorMittal has investments in various joint ventures and associate entities globally. The Company considers AMNS India (60% equity interest) joint venture to be of particular strategic importance, warranting more detailed disclosures to improve the understanding of its operational performance and value to the Group.

EBITDA (100% basis)	166	217	133	684	844

Sales increased by 6.5% to $1.6 billion in 4Q 2025 as compared to $1.5 billion in 3Q 2025, driven by a 16.9% increase in steel shipment volumes to a record high, partially offset by lower average steel selling prices.

EBITDA decreased by 23.7% to $166 million in 4Q 2025 as compared to $217 million in 3Q 2025, primarily due to a negative price-cost effect, partially offset by higher steel shipment volumes.

Dividend

The Board of Directors will submit to a shareholders' vote, at the next annual general meeting, a proposal to increase the dividend to $0.60 per share. The dividend payments would occur on a quarterly basis (to be paid in equal installments in March, June, September and December) taking into account that the first quarter dividend payment to be paid in March 2026 shall be an interim dividend.

Other recent developments

On December 04, 2025, Moody's Ratings upgraded the long-term issuer ratings of ArcelorMittal to Baa2 from Baa3. They also changed the outlook on ArcelorMittal to stable from positive.
On November 21, 2025, ArcelorMittal announced that 77,809,772 treasury shares had been cancelled the day before. Post cancellation, the Company held approximately 13.9 million treasury shares as of December 31, 2025, which will be used to service its commitments relating to its Long-Term Incentive Plan. As a result of this cancellation, ArcelorMittal now has 775,000,000 shares in issue.
On January 30, 2026, the Government of the Republic of Liberia and ArcelorMittal announced that they have signed an amendment to the existing Mineral Development Agreement (MDA), which was ratified on January 29, 2026, via the Liberian legislative process, extending the duration of the agreement to 2050, with a right to renew for a further 25 years. The Company is undertaking feasibility studies for further expansion of its iron ore asset beyond the current phase 2 capacity of 20Mtpa. The railway infrastructure is being expanded so it can transport up to 30Mt of iron ore annually. This railway capacity will be reserved for ArcelorMittal's use. Under the terms of the agreement ArcelorMittal will pay $200 million to the Government of Liberia for certain rights it acquires per the agreement, namely the mining rights extension and reserved access to railroad capacity the Company is investing in.

Impairment charges of $204 million in 12M 2025 primarily relates to announced divestment of Zenica integrated steel plant and Prijedor iron ore mining business in Bosnia for $194 million in 2Q 2025.
For 12M 2025, the Company reported an exceptional net gain of $871 million, which includes a $1,645 million net gain from the acquisition of Nippon Steel's 50% stake in ArcelorMittal Calvert partially offset by a $0.4 billion charge related to settling the purchase‑price dispute concerning Votorantim's long steel business in Brazil, exceptional charges totalling $194 million ($105 million of restructuring costs in Europe, $28 million related to Sustainable Solutions, and a non‑cash loss of $61 million arising from the sale of ArcelorMittal Zenica and Prijedor in Bosnia). For adjusted net income calculations, the Company also treated certain deferred tax asset and related deferred tax expense impacts as exceptional items: 4Q 2025 in the amount of $273 million; 2Q 2025 in the amount of $228 million.
See Appendix 4 for the reconciliation of adjusted net income and adjusted basic earnings per share.
September 2020 was the inception date of the ongoing share buyback programs. Under the new 10 million share buyback program launched in April 2025, the Company has repurchased 2 million shares (20% of the tranche) up to the end of 4Q 2025.
The estimate of potential additional contribution to EBITDA is based on assumptions once ramped up to full capacity and assuming prices/spreads generally in line with the averages of 2015-2020. Other projects under development include the construction of a new high added value finishing line (cold rolling mill) and a continuous coating line at Tubarão facility. The project is undergoing internal approvals, and ArcelorMittal Brasil is currently moving forward with detailed engineering (full feasibility study). As of December 31, 2025, last twelve-months investable cash flow of $1.9 billion consisting of cash flow from operations of $4.8 billion less normative/maintenance capex of $2.9 billion. As of December 31, 2025, last twelve-month capex of $4.3 billion included strategic capex of $1.1 billion and decarbonization capex of $0.3 billion.
Liquidity at the end of December 31, 2025, of $11.0 billion consisted of cash and cash equivalents of $5.5 billion (including cash and cash equivalents held as part of assets held for sale) and $5.5 billion of available credit lines. On April 30, 2025, the facility agent confirmed that all Revolving Credit Facility (RCF) lenders have agreed to our one-year extension request dated February 2, 2025. Consequently, the maturity of the ArcelorMittal $5.5 billion RCF is extended by one year to May 29, 2030.
Assets and liabilities held for sale are related to the announced divestment of Tubular subsidiary.
The acquisition of Votorantim's long steel business in Brazil in 2018 significantly strengthened ArcelorMittal's market position, adding approximately 2Mt of annual production capacity, increasing market share, and unlocking cost efficiencies alongside substantial operational, logistics, and procurement synergies. As part of the original deal structure, Votorantim and ArcelorMittal retained certain put and call option rights. In March 2022, Votorantim exercised its put option, resulting in a valuation dispute that proceeded to arbitration in Brazil. Following hearings in October 2024, the parties reached a settlement in June 2025, under which ArcelorMittal Brasil will pay approximately $546 million over three years.

Forward-Looking Statements

This document contains forward-looking information and statements about ArcelorMittal and its subsidiaries. These statements include financial projections and estimates and their underlying assumptions, statements regarding plans, objectives and expectations with respect to future operations, products and services, and statements regarding future performance. Forward-looking statements may be identified by the words "believe", "expect", "anticipate", "target", "projected", "potential", "intend" or similar expressions. Although ArcelorMittal's management believes that the expectations reflected in such forward-looking statements are reasonable, investors and holders of ArcelorMittal's securities are cautioned that forward-looking information and statements are subject to numerous risks and uncertainties, many of which are difficult to predict and generally beyond the control of ArcelorMittal, that could cause actual results and developments to differ materially and adversely from those expressed in, or implied or projected by, the forward-looking information and statements. These risks and uncertainties include those discussed or identified in the filings with the Luxembourg Stock Market Authority for the Financial Markets (Commission de Surveillance du Secteur Financier) and the United States Securities and Exchange Commission (the "SEC") made or to be made by ArcelorMittal, including ArcelorMittal's latest Annual Report on Form 20-F on file with the SEC. ArcelorMittal undertakes no obligation to publicly update its forward-looking statements, whether as a result of new information, future events, or otherwise.

Non-GAAP/Alternative Performance Measures

This press release also includes certain non-GAAP financial/alternative performance measures. ArcelorMittal presents EBITDA and EBITDA/tonne, free cash flow (FCF), adjusted net income and adjusted basic earnings per share which are non-GAAP financial/alternative performance measures, as additional measures to enhance the understanding of its operating performance. The definition of EBITDA includes income from share of associates, JVs and other investments (excluding impairments and exceptional items if any, of associates, JVs and other investments) because the Company believes this information provides investors with additional information to understand its results, given the increasing significance of its joint ventures. ArcelorMittal believes such indicators are relevant to provide management and investors with additional information. ArcelorMittal also presents net debt, liquidity and change in working capital as additional measures to enhance the understanding of its financial position, changes to its capital structure and its credit assessment. Investable cash flow is defined as net cash provided by operating activities less maintenance/normative capex, and the Company thus believes that it represents a cash flow that is available for allocation at management's discretion. The Company's guidance as to free cash flow and additional EBITDA estimated to be generated from certain projects is based on the same accounting policies as those applied in the Company's financial statements prepared in accordance with IFRS. ArcelorMittal is unable to reconcile, without unreasonable effort, such guidance to the most directly comparable IFRS financial measure, due to the uncertainty and inherent difficulty of predicting the occurrence and the financial impact of items impacting comparability. For the same reasons, ArcelorMittal is unable to address the significance of the unavailable information. Non-GAAP financial/alternative performance measures should be read in conjunction with, and not as an alternative to, ArcelorMittal's financial information prepared in accordance with IFRS. Comparable IFRS measures and reconciliations of non-GAAP financial/alternative performance measures are presented herein.
