References to the financial position and results of operations relate to the financial position and results of operations of Flame Aggregator, LLC. References to the “Company,” “we,” “us,” or “our” in these consolidated financial statements are to Flame Aggregator, LLC, together with its consolidated subsidiaries. 2.

Flame Aggregator, LLC Notes to Consolidated Financial Statements (continued) (In Thousands, Except Share Data) 7 3. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements included herein have been prepared in accordance with accounting principles generally accepted in the U.S. (“US GAAP”) for interim reporting. The financial statements are presented on a consolidated basis. All intercompany accounts and transactions have been eliminated. Certain information and disclosures normally included in financial statements have been omitted. In management’s opinion, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The results of operations for the period ended June 30, 2025 are not necessarily indicative of the operating results expected for the entire year. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2024. Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company bases its estimates on its experience and on various assumptions that are believed to be reasonable under the circumstances at the time. Actual amounts could differ from estimates under different assumptions or conditions. Concentration of Credit Risk Financial instruments that potentially subject the Company to credit risk consist primarily of accounts receivable. Accounts receivable are stated at amounts believed by management to be the net realizable value. Credit is extended to customers based on an evaluation of credit reports, payment practices, and, in most cases, financial condition. The Company provides an allowance for doubtful accounts based upon past history and considers economic circumstances surrounding particular customers. The Company writes off accounts receivable when it becomes apparent the amounts will not be collected. Accounts receivable are considered past due when payment has not been received within the standard payment terms; however, the Company does not accrue interest on past due accounts receivable.

Flame Aggregator, LLC Notes to Consolidated Financial Statements (continued) (In Thousands, Except Share Data) 8 3. Summary of Significant Accounting Policies (continued) Four customers accounted for 66% and 71% of accounts receivable as of June 30, 2025 and December 31, 2024, respectively. During the six months ended June 30, 2025 and the six months ended June 30, 2024 the Company had three customers that accounted for 62% and 64%, respectively, of consolidated net sales. Recent Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvement to Income Tax Disclosures.” ASU 2023-09 requires additional disclosures aimed at enhancing the transparency and decision usefulness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024, on a prospective basis. The Company is required to adopt the guidance for the fiscal year ending December 31, 2025, and does not expect this ASU to have a material impact on the Company’s disclosures. In November 2024, the FASB issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income (Topic 220): Disaggregation of Income Statement Expenses.” ASU 2024- 03 requires additional disclosures aimed at enhancing the transparency and decision usefulness of income statement expenses. This ASU is effective for fiscal years beginning after December 15, 2026 as well as interim periods beginning after December 15, 2027 and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of the guidance on the related disclosures. 4. Prepaid Expenses and Other Current Assets Prepaid expenses include insurance and expenses, vendor deposits, assets held for sale, and the fair value of foreign currency derivatives. At June 30, 2025, and December 31, 2024, the Company had $1.8 million and $1.7 million, respectively, of idle equipment that was held for sale, and classified in other current assets.

Flame Aggregator, LLC Notes to Consolidated Financial Statements (continued) (In Thousands, Except Share Data) 9 5. Accrued liabilities Accrued liabilities consisted of the following (in thousands): 6. Revenue Recognition The Company enters into long-term mill service agreements with its customers in the steel manufacturing space. Revenues associated with these service contracts include a monthly fixed- fee, variable charges correlated to customer production and/or slag processing volumes that merit a higher level of service, and fees for metal recovery. The service contracts are multi-year customer agreements due to the material customer investment required. Principally all plant and equipment owned by the Company are used in revenue-generating activities under these contracts. Billings (and payables) are typically monthly. Revenue recognition is based upon the transfer of services in amounts that reflect the consideration the Company is entitled to by the exchange. The Company believes the customer benefits from these services it provides on a continuous basis and is thus earned over time. Pricing is set per formal agreements. Depending on the individual contract, some level of periodic adjustment in variable revenue may be allowed based upon changes in production cost conditions. Less than 6% of the Company’s revenue is recognized from the tangible sales of steel and/or steel by-products and is earned point in time. These sales consist of sale of slag and scrap metal on behalf of, or directly back to, the Company’s steel mill customers, mixed with minimal third-party sales for the Company’s benefit. Sales, value add, and other taxes which the Company collects concurrent with income-producing activities are excluded from revenue. June 30, December 31, 2025 2024 (Unaudited) Employee compensation, benefits, and withholdings 9,021$ 9,968$ Professional Services 5,051 2,953 Other (none of which is individually significant) 11,424 8,960 Total Accrued Expenses 25,496$ 21,881$

Flame Aggregator, LLC Notes to Consolidated Financial Statements (continued) (In Thousands, Except Share Data) 10 7. Income Taxes We compute income tax expense for each quarter based on the estimated annual effective tax rate for the year, adjusted for certain discrete items. Our effective tax rate typically differs from the federal statutory tax rate due to business operations in foreign jurisdictions and the mixture of earnings attributed to those operations, Brazilian SUDENE tax holiday currently in effect, local country withholding tax obligations, and current period movement in existing uncertain tax positions. On July 4, 2025, H.R. 1, commonly known as the One Big Beautiful Bill Act (the “OBBB”), was signed into law. This includes significant changes to the federal corporate tax provisions and extends certain otherwise expiring provisions of the 2017 Tax Cuts and Jobs Act. Among other things, the legislation restores 100% bonus depreciation for eligible property, reinstates expensing for domestic research and experimental expenditures, imposes new limitations on interest expense deductibility, and expands disallowed deductions for certain employee remuneration. The OBBB also includes provisions that could impact our international business and which are still being evaluated. ASU 2023-09 Income Taxes (Topic 740) requires the effects of changes in tax rates and laws on deferred tax balances to be recognized in the period in which the relevant legislation is enacted. The OBBB was passed subsequent to the date of our financial statements and may affect the Company’s tax assets and liabilities in future periods. During the six months ended June 30, 2025 income tax expense was $1.5 million compared to $3.8 million for the same period in 2024. For the six months ended June 30, 2025, the effective tax rate was -13.9% compared to -32.6% for the same period in 2024. The change in the effective tax rate was primarily due to local country withholding tax obligations and movement in existing uncertain tax positions. 8. Derivatives The Company has operations in multiple international locations and generates income from operations in multiple currencies, principally the Brazilian real and South African rand. Therefore, the Company has risk exposure to unfavorable changes in the foreign currencies, with a resulting impact on its financial performance denominated in U.S. dollars. The Company’s risk management policy permits the use of derivatives to manage this exposure.

Flame Aggregator, LLC Notes to Consolidated Financial Statements (continued) (In Thousands, Except Share Data) 11 8. Derivatives (continued) The Company’s derivative contracts include cross-currency swap contracts that were put in place to better match the cash flows associated with the foreign operations of the Company denominated in Brazilian real and South African rand against its U.S. dollar denominated financial statements. The cross-currency swap contract effectively converted cash flows from foreign operations into USD-denominated cash flows at a fixed exchange rate. These instruments did not meet the criteria for hedge accounting, and, therefore, all changes in the market value of the financial instrument and all associated settlements are recognized as gains or losses in the period of change, in the consolidated statements of operations. As of June 30, 2025, and June 30, 2024 the Company recognized an unrealized gain for derivative mark-to-market changes of $66 and $493 respectively in other current assets in the balance sheet and other income (expense) of the consolidated statement of operations and comprehensive loss. 9. Fair Value Measurements The Company’s assets and liabilities that are recorded on the consolidated balance sheets at fair value on a recurring basis include cash and cash equivalents and derivative instruments. Financial assets and liabilities that are measured and reported at fair value are classified and disclosed in one of the following categories: • Level 1 – Quoted market prices in active markets for identical assets or liabilities • Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data • Level 3 – Unobservable inputs that are not corroborated by market data The fair value of the Company’s derivatives recognized in prepaid expenses and other current assets was $860 and $794 at June 30, 2025 and December 31, 2024 respectively. Our derivatives were measured at fair value on a recurring basis using Level 2 inputs as of June 30, 2025 and December 31, 2024.

Debt The Company’s debt consists of the following: First Lien Exit Facility Credit Agreement On June 30, 2023, the Company borrowed $45,000 principal amount in new money term loans (“New Money Exit Loans”) and converted the aggregate principal amount, plus accrued and unpaid obligations, of the initial term loans under the DIP Credit Facility into $60,919 principal amount of term loans (“Takeback Loans” and, together with the New Money Exit Loans, the “First Lien Exit Facility”). The New Money Exit Loans generated cash proceeds for the Company, whereas the Takeback Loans satisfied certain obligations under the DIP Credit Facility. The First Lien Exit Facility matures in 2028, amortizes at a rate of 0.25% per quarter, has a (non-cash) paid in-kind (“PIK”) interest feature at an annual rate of 4% and has a cash interest rate of either ABR plus 5% or Adjusted Term SOFR plus 6%.

The Company’s obligations under the First Lien Exit Facility are guaranteed by the Company and are secured by liens on substantially all assets of the Company. The First Lien Exit Facility contains certain affirmative and negative covenants, including limitations on, among other things, liens, acquisitions, consolidations, sales of assets, and incurrence of debt. If an event of default were to occur under the First Lien Exit Facility, the lenders would be entitled to declare all amounts borrowed under it immediately due and payable. The Company is required to maintain at least $10 million in cash and cash equivalents at the end of each month to satisfy the debt covenant.

Equity Incentive Plan (continued) a cumulative adjustment recorded to compensation expense. Unvested units are forfeited at termination for any reason. The Company has elected to recognize the effect of forfeitures in compensation expense when they occur.

The fair value was $11.89 per share for time-based awards and $7.95 per share for performance-based awards as of December 31, 2023. The fair value was materially consistent at December 31, 2024. The fair value at June 30, 2025 (unaudited) was $19.73 per share for time-based awards and performance- based awards, consistent with the fair value at the closing of the acquisition of the Company by SunCoke.

Equity Incentive Plan (continued) The Company utilizes estimates and assumptions in determining the fair value of each award on the date of grant. The Company estimated their fair value using the Monte Carlo Simulation approach. Estimates and assumptions that require the Company’s judgment include several objective and subjective factors, including probability weighting of events, volatility, time to an exit event, a risk-free interest rate, and a discount for lack of marketability. Changes to the key assumptions used in the valuations could result in different fair values at each valuation date. For the time-based restricted stock unit awards, the Company recorded $2,446 and $461 of compensation expense for the six months ended June 30, 2025, and the six months ended June 30, 2024, respectively, which is included in General and administrative expenses on the accompanying consolidated statement of operations and comprehensive income (loss). As of June 30, 2025 and December 31, 2024, there was $1,702 and $2,100, respectively of unrecognized compensation expense for the time-based awards, which is expected to be recognized over an estimated period of 1.0 years and 1.5 years, respectively. For the restricted stock unit awards where vesting is dependent upon achieving certain performance conditions, the Company has determined that it is not probable that the performance conditions will be achieved and, as such, has not recognized any compensation expense during the six months ended June 30, 2025, and the six months ended June 30, 2024. As of June 30, 2025, and December 31, 2024, there was approximately $7.3 million and $3.0 million of unrecognized compensation expense. 17.

Commitments and Contingencies (continued) The Company closed on the sale of its former French businesses in 2023. Due to the inherent complexity of multiple French entities, including the timing for completion of liquidation, the ultimate cash proceeds from the sale cannot be precisely estimated at this time nor does the Company anticipate any additional obligations from the divestiture. Accordingly, no amounts for the proceeds or additional obligations have been reflected in the accompanying consolidated financial statements, as such amounts are not both probable and reasonably estimated. 18. Subsequent Events The Company evaluated, for potential recognition and disclosure, events that occurred prior to the issuance of the accompanying consolidated financial statements through October 16, 2025.
