NEWS RELEASE
Cleveland-Cliffs Reports First-Quarter 2026 Results
CLEVELAND—April 20, 2026—Cleveland-Cliffs Inc. (NYSE: CLF) today reported first-quarter results for the period ended March 31, 2026.
First-Quarter Consolidated Results
•Steel shipments of 4.1 million net tons, a 338,000 increase from the prior quarter
•Revenues of $4.9 billion, a $600 million increase from the prior quarter
•GAAP net loss of $229 million, or $0.42 per diluted share
•Adjusted EBITDA2 of $95 million, inclusive of an $80 million one‑time energy cost impact driven by extreme cold weather
•Liquidity of $3.1 billion as of March 31, 2026
First-quarter 2026 consolidated revenues were $4.9 billion, compared to $4.6 billion in the first quarter of 2025 and $4.3 billion in the fourth quarter of 2025.
For the first quarter of 2026, the Company recorded a GAAP net loss of $229 million, or $0.42 per diluted share, with an adjusted net loss1 of $0.40 per diluted share. This compares to a first quarter 2025 GAAP net loss of $486 million, or $1.01 per diluted share, with an adjusted net loss1 of $0.93 per diluted share; and a fourth quarter 2025 GAAP net loss of $235 million, or $0.44 per diluted share, with an adjusted net loss1 of $0.43 per diluted share.
For the first quarter of 2026, the Company reported Adjusted EBITDA2 of $95 million, which included an $80 million negative one-time impact due to a cold-weather driven energy price spike. This compares to an Adjusted EBITDA2 loss of $179 million and $21 million recorded in the first and fourth quarter of 2025, respectively.
Cliffs’ Chairman, President and CEO, Lourenco Goncalves, said: “Q1 results reflected the impact of short-term headwinds like energy prices and price realization lags. As we move through the year, each quarter is expected to improve sequentially, as the momentum already visible in both our order book and pricing continues to translate into earnings and cash flow. Importantly, we expect to generate healthy positive free cash flow in the second quarter, marking a return to the earnings and cash-generation profile this company is capable of delivering."

Mr. Goncalves added: "Trade enforcement in the United States is working exactly as intended, with steel imports at their lowest levels since the global financial crisis. Recent actions related to derivative products have brought needed clarity to the market, supporting manufacturing in the United States and creating new jobs for American workers. Additionally, we continue to request the Canadian government to further enhance its own defenses toward the achievement of what we call both in Canada and the United States 'Fortress North America.' At this point we feel encouraged by the level of understanding demonstrated by key Canadian officials to the urgency of resolving the problem and preserving Canadian jobs currently at risk."
Mr. Goncalves concluded: "Ongoing disruption in the Middle East has made Cliffs' competitive position stronger and underscores why global steel producers want to partner with Cleveland-Cliffs. While the current situation has not helped the timeline of a potential deal with POSCO, we continue to negotiate in good faith within the framework of our MoU toward a transaction that is accretive for our shareholders and fully reflects the value of our assets, our market position, and the strength of the U.S. steel demand."

Forward-Looking Statements
This release contains statements that constitute "forward-looking statements" within the meaning of the federal securities laws. As a general matter, forward-looking statements relate to anticipated trends and expectations rather than historical matters. Forward-looking statements are subject to uncertainties and factors relating to our operations and business environment that are difficult to predict and may be beyond our control. Such uncertainties and factors may cause actual results to differ materially from those expressed or implied by the forward-looking statements. These statements speak only as of the date of this release, and we undertake no ongoing obligation, other than that imposed by law, to update these statements. Investors are cautioned not to place undue reliance on forward-looking statements. Uncertainties and risk factors that could affect our future performance and cause results to differ from the forward-looking statements in this release include, but are not limited to: continued volatility of steel, scrap metal and iron ore market prices, which directly and indirectly impact the prices of the products that we sell to our customers; uncertainties associated with the highly competitive and cyclical steel industry and our reliance on the demand for steel from the automotive industry; potential weaknesses and uncertainties in global economic conditions, excess global steelmaking capacity and production, prevalence of steel imports and reduced market demand; severe financial hardship, bankruptcy, temporary or permanent shutdowns or operational challenges of one or more of our major customers, key suppliers or contractors, which, among other adverse effects, could disrupt our operations or lead to reduced demand for our products, increased difficulty collecting receivables, and customers and/or suppliers asserting force majeure or other reasons for not performing their contractual obligations to us; risks related to U.S. and Canadian government actions and other countries' reactions with respect to Section 232 of the Trade Expansion Act of 1962 (as amended by the Trade Act of 1974), the United States-Mexico-Canada Agreement and/or other trade agreements, tariffs, treaties or policies, as well as the uncertainty of obtaining and maintaining effective antidumping and countervailing duty orders to counteract the harmful effects of unfairly traded imports; impacts of extensive governmental regulation, including actual and potential environmental regulations relating to climate change and carbon emissions, and related costs and liabilities, including failure to receive or maintain required operating and environmental permits, approvals, modifications or other authorizations of, or from, any governmental or regulatory authority and costs related to implementing improvements to ensure compliance with regulatory changes, including potential financial assurance requirements, and reclamation and remediation obligations; potential impacts to the environment or exposure to hazardous substances resulting from our operations; our ability to maintain adequate liquidity, our level of indebtedness and the availability of capital could limit our financial flexibility and cash flow necessary to fund working capital, planned capital expenditures, acquisitions, and other general corporate purposes or ongoing needs of our business, or to repurchase our common shares; our ability to reduce our indebtedness or return capital to shareholders within the currently expected timeframes or at all; adverse changes in credit ratings, interest rates, foreign currency rates and tax laws; risks and uncertainties related to our ability to realize the anticipated synergies or other expected benefits of any acquisitions, including the acquisition of Stelco, any potential transaction arising out of our Memorandum of Understanding with POSCO and completing any proposed asset divestiture transactions; challenges to successfully implementing our business strategy to achieve operating results in line with our guidance; the outcome of, and costs incurred in connection with, lawsuits, claims, arbitrations or governmental proceedings relating to commercial and business disputes, antitrust claims, environmental matters, government investigations, occupational or personal injury claims, property-related matters, labor and employment matters, mineral royalty disputes, or suits involving legacy operations and other matters; supply chain disruptions or changes in the cost, quality or availability of energy sources, including electricity, natural gas and diesel fuel, water, critical raw materials and supplies, including iron ore, industrial gases, graphite electrodes, scrap metal, chrome, zinc, other alloys, coke and metallurgical coal, and critical manufacturing equipment and spare parts, including as a result of geopolitical conflicts; problems or disruptions associated with transporting products to our customers, moving manufacturing inputs or products internally among our facilities, or suppliers transporting raw materials and spare parts to us; our ability to implement strategic or sustaining capital projects on time and on budget; uncertainties associated with natural or human-caused disasters, adverse weather conditions, unanticipated geological conditions, critical equipment failures, infectious disease outbreaks, tailings dam failures and other unexpected events; cybersecurity incidents relating to, disruptions in, or failures of, information technology systems that are managed by us or third parties that host or have access to our data or systems, including the loss, theft or corruption of our or third parties' sensitive or essential business or personal information and the inability to access or control systems; emerging risks related to the adoption and regulation of artificial intelligence, including our ability to achieve the expected benefits of our adoption of information technology platforms that use artificial intelligence; liabilities and costs arising in connection with business decisions to temporarily or indefinitely idle or permanently close an operating facility or mine, which could adversely impact the carrying value of associated assets and give rise to impairment charges or closure and reclamation obligations, as well as uncertainties associated with resuming production at any previously idled operating facility or mine; our level of self-insurance and our ability to obtain sufficient third-party insurance to adequately cover potential adverse events and business risks; uncertainties associated with our ability to meet customers’ and suppliers’ decarbonization goals and reduce our emissions in alignment with our own announced targets; challenges to maintaining our social license to operate with our stakeholders, including the impacts of our operations on local communities, reputational impacts of operating in a carbon-intensive industry that
4
produces greenhouse gas emissions, and our ability to foster a consistent operational and safety track record; our actual economic mineral reserves or reductions in current mineral reserve estimates, and any title defect or loss of any lease, license, option, easement or other possessory interest for any mining property; our ability to complete technical and economic studies to determine the potential for economic extraction of rare earth minerals at our mining properties, and the risk that rare-earth extraction at our properties may not be economically viable; our ability to maintain satisfactory labor relations with unions and our employees; unanticipated or higher costs associated with pension and other postretirement benefits obligations resulting from changes in the value of plan assets or contribution increases required for unfunded obligations, including for multiemployer plan withdrawal liability; uncertain availability or cost of skilled workers to fill critical operational positions and potential labor shortages caused by experienced employee attrition or otherwise, as well as our ability to attract, hire, develop and retain key personnel; and potential significant deficiencies or material weaknesses in our internal control over financial reporting.
For additional factors affecting the business of Cliffs, refer to Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2025, and other filings with the U.S. Securities and Exchange Commission.
