Delivering Strong Sales Volume Growth

Reaffirming Full-Year Volume and Cost Expectations

Executing Pricing Actions and Other Strategic Initiatives to Support Long-term Value

GrafTech International Ltd. (NYSE: EAF) ("GrafTech," the "Company," "we," or "our") today announced its unaudited financial results for the quarter ended March 31, 2026.

First Quarter 2026 Summary

• Sales volume of 28.1 thousand MT, an increase of 14% year-over-year
• Net sales of $125 million, an increase of 12% year-over-year
• Net loss of $43 million, or $1.66 per share⁽¹⁾
• Adjusted EBITDA⁽²⁾ of negative $14 million

CEO Comments

"We delivered 14% year-over-year sales volume growth in the first quarter and remain on track to meet our full-year volume expectation," said Timothy Flanagan, Chief Executive Officer and President. "However, supply-side imbalance, driven by overcapacity that has been built in both China and India, translates into a current pricing environment that remains unsustainably weak. Our focus on commercial execution and disciplined cost management, combined with our $329 million liquidity position, allows us to maintain stability while we take actions to address these conditions."

"We are taking decisive steps to restore more sustainable market dynamics and support the long-term viability of our business and our industry," continued Mr. Flanagan. "These include implementing price increases on uncommitted volume and actively supporting trade cases in key jurisdictions. We believe these actions are necessary to correct market imbalances. We remain committed to providing reliable supply to our customers while improving our financial performance and delivering long-term shareholder value."

First Quarter 2026 Financial Performance

Net sales for the first quarter of 2026 were $125 million, an increase of 12% compared to $112 million for the first quarter of 2025, reflecting higher sales volume partially offset by a year-over-year decrease in our weighted-average realized price.

Net loss for the first quarter of 2026 was $43 million, or $1.66 per share, compared to a net loss of $39 million, or $1.52 per share, for the first quarter of 2025. Adjusted EBITDA⁽²⁾ was negative $14 million for the first quarter of 2026, compared to adjusted EBITDA⁽²⁾ of negative $4 million for the first quarter of 2025, with the year-over-year change primarily reflecting the decline in the weighted-average realized price.

For the first quarter of 2026, net cash used in operating activities was $15 million and adjusted free cash flow⁽²⁾ was negative $27 million, compared to net cash used in operating activities of $32 million and adjusted free cash flow⁽²⁾ of negative $40 million for the first quarter of 2025. The year-over-year improvement primarily reflected changes in working capital, including a planned inventory build in the first quarter of 2025.

Operational and Commercial Update

Sales volume for the first quarter of 2026 was 28.1 thousand MT, an increase of 14% compared to the first quarter of 2025. For the first quarter of 2026, our weighted-average realized price was approximately $3,900 per MT, representing a 5% decrease compared to the first quarter of 2025. The year-over-year pricing decline reflected persistent competitive pressures across most of our principal commercial regions, partially mitigated by favorable mix as we achieved 37% sales volume growth in the United States, which remains the strongest region for graphite electrode pricing.

Production volume was 29.4 thousand MT for the first quarter of 2026, resulting in a capacity utilization rate of 65% for the quarter.

Capital Structure and Liquidity

As of March 31, 2026, we had total liquidity of $328.7 million, consisting of cash and cash equivalents of $120.2 million, $108.5 million of availability under our revolving credit facility and $100.0 million of availability under our senior secured first lien delayed draw term loans, which continues to support our ability to manage through the near-term, industry-wide challenges. As of March 31, 2026, we had gross debt⁽⁶⁾ of $1,125 million, with substantially no maturities until December 2029, and net debt⁽⁷⁾ of approximately $1,005 million.

Outlook

Demand for graphite electrodes is expected to improve modestly in 2026, supported by stable-to-improving steel production trends outside of China. While steel market conditions remain mixed, in the United States, demand has been relatively stable and is expected to increase modestly, with steel production further supported by favorable trade policies. In Europe, steel industry conditions have been more challenged, though there are early signs of recovery, including expected demand growth and recently approved increases in trade protections. For GrafTech, we continue to expect a 5–10% year-over-year increase in graphite electrode sales volume for 2026, with more than 85% of our anticipated volume already committed in our order book.

While volume trends are stable, current industry-wide pricing levels do not reflect the indispensable nature of graphite electrodes for electric arc furcnace steelmaking. As a result, we are taking deliberate actions to restore more sustainable pricing and improve our profitability. These include implementing price increases of $600 to $1,200 per metric ton on uncommitted volume, actively supporting graphite electrode trade cases in key jurisdictions, including the United States and Brazil, continuing to optimize our order book by prioritizing higher-value regions and foregoing volume opportunities where margins are unacceptably low.

On costs, geopolitical developments continue to impact key input costs, including oil-based raw materials, energy and logistics. In response, we are expanding initiatives to improve our cost structure, including enhancing production efficiency and optimizing production schedules. Factoring all of this in, we continue to expect a low single-digit percentage-point decline in our cash cost of goods sold per MT for 2026 compared to 2025.

We are also maintaining disciplined capital and working capital management. For 2026, we expect a modest increase in working capital for the full year to support higher volume. We continue to anticipate our full-year capital expenditures will be approximately $35 million, consistent with maintaining our assets at current utilization levels.

Longer term, we remain confident in the structural drivers of demand growth for graphite electrodes. The ongoing shift toward electric arc furnace steelmaking and growing demand for petroleum needle coke in battery applications are expected to support sustained industry growth. We believe the actions we are taking, combined with our vertical integration and a leading competitive position, will enable GrafTech to benefit as market conditions normalize.

Non‑GAAP Financial Measures

In addition to providing results that are determined in accordance with GAAP, we have provided certain financial measures that are not in accordance with GAAP. EBITDA, adjusted EBITDA, adjusted net loss, adjusted loss per share, free cash flow, adjusted free cash flow, net debt and cash cost of goods sold per MT are non-GAAP financial measures.

We define EBITDA, a non‑GAAP financial measure, as net loss plus interest expense, minus interest income, plus income taxes and depreciation and amortization. We define adjusted EBITDA, a non-GAAP financial measure, as EBITDA adjusted by any pension and other post-employment benefit ("OPEB") expenses, non‑cash gains or losses from foreign currency remeasurement of non‑operating assets and liabilities in our foreign subsidiaries where the functional currency is the U.S. dollar, stock-based compensation expense, gains on asset sales and Tax Receivable Agreement adjustments. Adjusted EBITDA is the primary metric used by our management and our Board of Directors to establish budgets and operational goals for managing our business and evaluating our performance.

We monitor adjusted EBITDA as a supplement to our GAAP measures, and believe it is useful to present to investors, because we believe that it facilitates evaluation of our period‑to‑period operating performance by eliminating items that are not operational in nature, allowing comparison of our recurring core business operating results over multiple periods unaffected by differences in capital structure, capital investment cycles and fixed asset base. In addition, we believe adjusted EBITDA and similar measures are widely used by investors, securities analysts, ratings agencies, and other parties in evaluating companies in our industry as a measure of financial performance and debt‑service capabilities.

We define adjusted net loss, a non‑GAAP financial measure, as net loss, excluding the items used to calculate adjusted EBITDA and further excluding debt modification costs, less the tax effect of those adjustments and non-cash income tax expense related to the establishment of a deferred tax valuation allowance. We define adjusted loss per share, a non‑GAAP financial measure, as adjusted net loss divided by the weighted average diluted common shares outstanding during the period. We believe adjusted net loss and adjusted loss per share are useful to present to investors because we believe that they assist investors’ understanding of the underlying operational profitability of the Company.

We define free cash flow, a non-GAAP financial measure, as net cash provided by or used in operating activities less capital expenditures. We define adjusted free cash flow, a non-GAAP financial measure, as free cash flow adjusted by payments made for debt modification costs. We use free cash flow and adjusted free cash flow as critical measures in the evaluation of liquidity in conjunction with related GAAP amounts. We also use these measures when considering available cash, including for decision-making purposes related to dividends and discretionary investments. Further, these measures help management, the Board of Directors, and investors evaluate the Company's ability to generate liquidity from operating activities.

We define net debt, a non-GAAP financial measure, as gross debt minus cash and cash equivalents. We believe this is an important measure as it is more representative of our financial position.

We define cash cost of goods sold per MT, a non-GAAP financial measure, as cost of goods sold less depreciation and amortization and less cost of goods sold associated with the portion of our sales that consists of deliveries of by-products of the manufacturing processes, with this total divided by our sales volume measured in MT. We believe this is an important measure as it is used by our management and Board of Directors to evaluate our costs on a per MT basis.

In evaluating these non-GAAP financial measures, you should be aware that in the future, we may incur expenses similar to the adjustments in the reconciliations presented below. Our presentations of these non-GAAP financial measures should not be construed as suggesting that our future results will be unaffected by these expenses or any unusual or non‑recurring items. When evaluating our performance, you should consider these non-GAAP financial measures alongside other measures of financial performance and liquidity, including our net loss, loss per share, cash flow from operating activities, cost of goods sold and other GAAP measures.
