    NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
    (In thousands, except share and per share amounts)

    1.Overview
    Nature of Operations
    Eos Energy Enterprises, Inc. (the “Company,” “we,” “us,” “our,” and “Eos”) designs, develops, manufactures and markets innovative energy storage solutions for utility-scale, microgrid and commercial & industrial (“C&I”) applications. Eos developed a broad range of intellectual property with multiple patents covering unique battery chemistry, mechanical product design, energy block configuration and a software operating system (Battery Management System). The Company has only one operating and reportable segment.
    Liquidity and Going Concern
    As a growth company in the early commercialization stage of its lifecycle, Eos is subject to inherent risks and uncertainties associated with the development of an enterprise. In this regard, substantially all of the Company’s efforts to date have been devoted to the development and manufacturing of battery energy storage systems and complementary products and services, recruitment of management and technical staff, deployment of capital to expand the Company’s operations to meet customer demand and raising capital to fund the Company’s development. However, as a result of these efforts, the Company has incurred significant losses and negative cash flows from operations since its inception and expects to continue to incur such losses and negative cash flows for the foreseeable future until such time that the Company can reach a scale of profitability to sustain its operations.
    In order to execute its development strategy, the Company has historically relied on outside capital through the issuance of equity, debt and borrowings under financing arrangements (collectively “outside capital”) to fund its cost structure. While the Company believes its recent entry into new credit facilities as discussed below has significantly improved its capital position and provides a path to sustainable operations and profitability, there can be no assurance the Company will be able to achieve such profitability or do so in a manner that does not require additional outside capital. Moreover, while the Company has historically been successful in raising outside capital, there can be no assurance the Company will be able to continue to obtain outside capital in the future or do so on terms that are acceptable to the Company.
    As disclosed in Note 3, Credit and Securities Purchase Transaction, on June 21, 2024, the Company entered into a financing transaction with CCM Denali Debt Holdings, LP, an affiliate of Cerberus Capital Management LP (herein after referred to as “Cerberus”, “Denali”, “Lender”, “Holder”). As a result of this transaction, Cerberus agreed to provide a $210,500 secured multi-draw facility, to be made in four installments (the “Delayed Draw Term Loan”) as well as a $105,000 revolving credit facility (“Revolving Facility”), to be made available beginning June 21, 2026, at Cerberus’ sole discretion and only if the Delayed Draw Term Loan is fully funded. As of the date the accompanying Unaudited Condensed Consolidated Financial Statements were issued (the “issuance date”), the Delayed Draw Term Loan was fully funded. As part of the Credit and Securities Purchase Transaction, Cerberus received warrants and preferred stock resulting in a 33% ownership position in the Company as of the issuance date. This ownership percentage represents $814,346 in market capitalization based on the May 01, 2025 closing share price of the Company’s common stock.

    NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

    1. Overview (cont.)
    As disclosed in Note 13, Borrowings, on November 26, 2024, the Company successfully closed on the DOE Loan Facility, which provides the Company with up to $303,450 in funding, including capitalized interest, subject to the achievement of certain funding conditions. The DOE Loan Facility provides for a multi draw term loan facility under a series of at least two tranches and, if the Company elects, up to four tranches, subject to the achievement of certain conditions. Each tranche corresponds to the production, maintenance and development, and operation of a given production line to be funded using the proceeds of such tranche. The DOE Loan Facility specifies the maximum amount subject to each tranche (Tranche 1: $101,979; Tranche 2: $117,326; Tranche 3: $71,836; and Tranche 4: $12,309), and any amounts which are not withdrawn under a specified tranche cannot be allocated to another tranche. Through March 31, 2025, the Company had drawn down $68,279 under Tranche 1.
    As of the issuance date, management evaluated the significance of the following negative financial conditions in accordance with Accounting Standard Codification 205-40, Going Concern:
    •Since its inception, the Company has incurred significant losses and negative cash from operations in order to fund its development. During the three months ended March 31, 2025, the Company had net income of $15,136. Adjustments to reconcile net income to cash used in operations are primarily from non-cash items on the Unaudited Condensed Consolidated Statements of Cash Flows. The non-cash items totaled $60,855. The Company incurred negative cash flows from operations of $28,924 and had an accumulated deficit of $1,546,580 as of March 31, 2025.
    •As of March 31, 2025, the Company had $82,553 of unrestricted cash and cash equivalents available to fund the Company’s operations and working capital of $94,806.
    •On June 21, 2024, upon closing of the Credit and Securities Purchase Transaction, Cerberus funded the Company $75,000 of the initial draw, and the Company received $71,250, net of the 5.0% original issue discount. On August 29, 2024, Cerberus funded the Company $30,000 (“August Draw”), and the Company received $28,500, net of the 5.0% original issue discount. On November 1, 2024, Cerberus funded the Company $65,000 related to the October 31, 2024 tranche (“October Draw” or “October Tranche”), and the Company received $61,750, net of the 5.0% original issue discount. On January 24, 2025, Cerberus funded the Company the final $40,500 and the Company received $38,475, net of the 5.0% original issue discount, related to the January 31, 2025 tranche (“January 2025 Draw”).

    •Through March 31, 2025, under the DOE Loan Facility, the Company drew down $68,279 for the eligible project cost that the Company had incurred through December 6, 2024. These costs are a portion of Tranche 1 of the DOE Loan Facility. Tranche 1 provides up to $101,979 for eligible costs in connection with the design, construction, installation, startup and shakedown of a battery automation line and related tools. In the event the Company does not achieve certain funding milestone conditions and the DOE chooses not to continue funding, the Company would need to seek alternative sources of capital, which may not be available on favorable terms or at all.

    1. Overview (cont.)
    •The Credit and Securities Purchase Transaction and the DOE Loan Facility contain certain quarterly financial covenants which include (a) Minimum Liquidity, (b) Minimum Consolidated EBITDA, and (c) Minimum Consolidated Revenue (collectively, the “financial covenants”). As of March 31, 2025, the only financial covenant in effect was Minimum Liquidity. As of March 31, 2025, the Company was in compliance with this covenant and non-financial covenants, and the Company expects to remain in compliance with the Minimum Liquidity covenant over the next twelve months beyond the issuance date. The Minimum Consolidated EBITDA and Minimum Consolidated Revenue financial covenants become effective beginning December 31, 2025. As of March 31, 2025, the Company expects that it may be unable to remain in compliance with the Minimum Consolidated EBITDA and Minimum Consolidated Revenue financial covenants beginning December 31, 2025, absent the Company’s ability to secure a waiver or amend the Credit and Securities Purchase Transaction and the DOE Loan Facility. The Company continues to be in regular communication with Cerberus and DOE regarding these covenants. In the event the Company is unable to comply with the financial and non-financial covenants beginning December 31, 2025, and the Company is unable to secure a waiver, Cerberus and the DOE may, at their discretion, enter into a forbearance agreement with the Company and/or exercise any and all of their existing rights and remedies, which may include, among other things, asserting their rights in the Company’s assets securing the loans. Moreover, the Company’s other lenders may exercise similar rights and remedies under the cross-default provisions of their respective borrowing agreements with the Company.
    •In the event the Company’s ongoing efforts to raise additional outside capital are unsuccessful, the Company will be unable to meet its obligations as they come due over the next twelve months beyond the issuance date. In such an event, management will be required to seek other strategic alternatives, which may include, among others, a significant curtailment in the Company’s operations, a sale of certain of the Company’s assets, a sale of the entire Company to strategic or financial investors and/or allowing the Company to become insolvent.
    These uncertainties raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared on the basis that the Company will continue to operate as a going concern, which contemplates that the Company will be able to realize assets and settle liabilities and commitments in the normal course of business for the foreseeable future. Accordingly, the accompanying Unaudited Condensed Consolidated Financial Statements do not include any adjustments that may result from the outcome of these uncertainties.
    2. Summary of Significant Accounting Policies
    Basis of Presentation
    The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of the Company and its 100% owned, direct and indirect subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). All intercompany transactions and balances have been eliminated in the preparation of the Unaudited Condensed Consolidated Financial Statements. These statements reflect all adjustments, consisting of normal recurring adjustments, which, in the opinion of management, are necessary for fair presentation of the information contained therein. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). The interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in our 2024 Annual Report on Form 10-K. These interim results are not necessarily indicative of results for the full year.
    Use of Estimates
    The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.

    2. Summary of Significant Accounting Policies (cont.)
    Change to Prior Year Presentation
    In the Unaudited Condensed Consolidated Statements of Operations, Gross profit (loss) has been introduced, reflecting Total revenue less Cost of goods sold. This addition does not impact the reported Net income (loss).
    Series A and B Preferred Stock
    As discussed in Note 3, Credit and Securities Purchase Transaction, the Company issued shares of (1) Series A-1 Preferred Stock and Series A-2 Preferred Stock (collectively "Series A Preferred Stock") in June 2024 and August 2024, respectively, which were subsequently converted into shares of Series B-1 Preferred Stock and Series B-2 Preferred Stock, respectively, in September 2024, (2) Series B-3 Preferred Stock in November 2024 and Series B-4 Preferred Stock in January 2025 (collectively, with the Series B-1 Preferred Stock, Series B-2 Preferred Stock, Series B-3 Preferred Stock and Series B-4 Preferred Stock, the “Series B Preferred Stock” and together with Series A Preferred Stock, “the Preferred Stock”). The Preferred Stock is redeemable based upon the passage of time and therefore meets the criteria to be classified within temporary equity. Management has elected to recognize changes in the redemption value pursuant to ASC 480-10-S99-3A-15(b). As a result, the Company will remeasure the Preferred Stock to the maximum redemption value at each reporting date but will never be adjusted below its initial carrying value. Adjustments are reflected in Additional paid in capital on the Company’s Unaudited Condensed Consolidated Balance Sheets.
    Production Tax Credits under Internal Revenue Code 45X (“PTC”)
    Since the PTC is a refundable credit (i.e., a credit with a direct-pay option available), the PTC is outside the scope of ASC 740. Therefore, the Company accounts for the PTC under a government grant model. GAAP does not address the accounting for government grants received by a business entity that are outside the scope of ASC 740. The Company’s accounting policy is to analogize to IAS 20, Accounting for Government Grants and Disclosure of Government Assistance, under IFRS Accounting Standards. Under IAS 20, once it is reasonably assured that the entity will comply with the conditions of the grant, the grant money is recognized on a systematic basis over the periods in which the entity recognizes the related expenses or losses for which the grant money is intended to compensate. The Company recognizes grants once it is probable that both of the following conditions will be met: (1) the Company is eligible to receive the grant and (2) the Company is able to comply with the relevant conditions of the grant. The PTC is a non-monetary asset since the Company’s intention is to sell the tax credit to a third-party and is recorded at the value that is expected to be received from the sale in Grant Receivable, net on the Company’s Unaudited Condensed Consolidated Balance Sheets and is subsequently recognized in Cost of goods sold in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) when the inventory is sold. In the event the PTC is sold, upon the receipt of the cash payments, the Company will record offsets to Grant Receivable, net. Differences in the recorded value of the PTC and the sale price will be recognized as an adjustment to cost of goods sold in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
    Fair Value Option
    The Company has elected the option under ASC 825-10, Financial Instruments ("ASC 825"), to measure the Delayed Draw Term Loan, including all tranches of fundings received in 2024 (see Note 3, Credit and Securities Purchase Transaction) at fair value. The fair value option may be elected on an instrument-by-instrument basis and is irrevocable unless a new election date occurs. When the fair value option is elected for an instrument, unrealized gains and losses for such instrument is reported in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) at each subsequent reporting date. Upfront costs and fees related to items for which the fair value option is elected shall be recognized in earnings as incurred and not deferred. These amounts are included in Other expense in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). The gains or losses attributable to changes in instrument-specific risk are included in Change in fair value of debt - credit risk - related party in Accumulated other comprehensive loss.

    Recent Accounting Pronouncements
    In October 2023, the FASB issued ASU 2023-06, Disclosure Agreements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This amendment will impact various disclosure areas, including the statement of cash flows, accounting changes and error corrections, earnings per share, debt, equity, derivatives, and transfers of financial assets. The amendments in this ASU 2023-06 will be effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC. If the SEC has not removed the applicable disclosure requirement by June 30, 2027, these amendments will not be effective. Early adoption is prohibited. The Company is currently assessing the potential impact this amendment could have on its disclosures.
    In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which requires additional disclosures related to the effective tax rate reconciliation and taxes paid. The amendment is effective for annual periods beginning after December 15, 2024, and the Company does not anticipate a material change in the financial statements and related disclosure.
    In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update require disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. This update is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, though early adoption is permitted. The Company is currently assessing the potential impact this amendment could have on its financial statements and disclosures.

This update is effective for annual periods beginning after December 15, 2025, including interim periods within those fiscal years, though early adoption is permitted. The Company is currently assessing the potential impact this amendment could have on its financial statements and disclosures.

ASU 2025-01 is effective for fiscal years beginning after December 15, 2027. Early adoption is permitted. Entities should apply the amendments in ASU 2023-07 retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting ASU 2025-01 and does not expect it to have a material impact on the Company’s financial position, results of operations and cash flows.

    3. Credit Agreement and Securities Purchase Transaction (cont.)
    On November 26, 2024, the Company amended the Credit Agreement (the “Credit Agreement Amendment”), by and among the Company, certain of the Company’s subsidiaries as guarantors party thereto and the Lender, pursuant to which among other things, the applicability of the Consolidated Revenue and EBITDA financial covenants were deferred until December 31, 2025 and certain provisions were amended to conform with comparable provisions in the DOE Loan Facility. See Note 13, Borrowings, for further discussion.
    Securities Purchase Agreement
    On June 21, 2024, the Company entered into a Securities Purchase Agreement (the “SPA”) with CCM Denali Equity Holdings, LP (the “Purchaser”).
    SPA Warrant
    Under the SPA, the Company issued a warrant to purchase 43,276,194 shares of common stock representing a collective ownership of 19.9% (the “SPA Warrant”) of our outstanding shares of (inclusive of Series A-1 Preferred Stock – see below) common stock prior to the issuance. The SPA Warrant has a ten-year term and an exercise price of $0.01 per share. The SPA Warrant includes anti-dilutive rights, subject to certain excluded issuances, in the event any shares of common stock, options, warrants, convertible securities or other equity or equity equivalent securities payable in common stock are issued at a price per share of less than the fair market value (as defined in the Warrant) of a share of common stock on the issuance date of the Warrant, subject to adjustment. Until the Company received stockholder approval on September 10, 2024, the Company could not issue additional shares of common stock exceeding 19.99% of shares of common stock issued and outstanding as of the date of the Initial Draw (such percentage, as may be adjusted in accordance with the terms of the Warrant, the “Conversion Cap”) upon exercise of the Warrant, and would have been required to issue, at the option of the Lender, Series A Preferred Stock or additional warrants on common stock upon a draw under the Delayed Draw Term Loan. Following shareholder approval received, the Conversion Cap increased to 49.9% of the number of shares of common stock issued and outstanding as of the applicable measurement date; and the holder of the Warrant has the option to amend the Conversion Cap to any percentage less than 49.9%.
    The SPA Warrant is exercisable at the holder’s discretion for cash or on a cashless basis. The SPA Warrant is subject to automatic cashless exercise on the expiration date if the fair market value of one share is greater than the exercise price then in effect. Upon an acceleration under the Credit Agreement, the Company may be required to purchase the SPA Warrant from the holder at an amount equal to the closing sale price of underlying common stock less the SPA Warrant exercise price at the request of the holder. The SPA Warrant meets the criteria for liability classification under ASC 480 and is recognized at fair value with changes in fair value included in Change in fair value of derivatives - related parties in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
    Contingent Warrants
    Upon the achievement of performance milestones on dates specified in the Credit Agreement, the Company received additional funds and issued at the option of the Lender, Preferred Stock (Series A Preferred Stock, if prior to shareholder approval or Series B Preferred Stock if after shareholder approval) or warrants on common stock (collectively “Contingent Warrants”) under the SPA in an amount equal to the applicable percentage, up to an aggregate of 33.0% ownership limitation on a fully diluted basis at such time the Delayed Draw Term Loan is fully drawn. As of the balance sheet date the applicable percentage is subject to increase by up to 4.0% to up to 37.0% on a fully diluted basis to the extent that milestones are not met on the final measurement date on April 30, 2025, in which case additional Contingent Warrants would be issuable. See Note 22, Subsequent Events, for further discussion of the applicable percentage and final measurement date. The Contingent Warrants meet the criteria for liability classification under ASC 480. The change in fair value of the Contingent warrants is included in Change in fair value of derivatives - related parties on the Company’s Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). See Note 14, Warrants Liability, for further discussion of the SPA Warrant and Contingent Warrants.

    On June 21, 2024, the Company filed with the Secretary of State of the State of Delaware the Series A-1 Certificate of Designation and issued 59 shares of Series A-1 Preferred Stock to satisfy the terms of the Credit Agreement. Under the terms of the Series A-1 Certificate of Designation, each share of Series A-1 Preferred Stock had an original issue price of $455,822.59 (the “A-1 Original Issue Price”) and a liquidation value, payable with the common stock, as if such shares were convertible into an aggregate of 31,940,063 shares of common stock, subject to adjustment. The Series A-1 Preferred Stock was non-voting and non-convertible into common stock. Holders of the Series A-1 Preferred Stock were entitled to receive dividends or distributions on each share of Series A-1 Preferred Stock equal to dividends or distributions actually paid on each share of common stock, multiplied by the number of shares of common stock represented by the Series A-1 Preferred Stock Liquidation Value (as defined in the Series A-1 Certificate of Designation).

The Series A-2 Preferred Stock terms were substantially identical to the Series A-1 Preferred Stock.
    On August 29, 2024, in connection with the August Draw, and pursuant to the terms and conditions of the Credit Agreement between the Company and Cerberus, the applicable percentage increased by 4.9%, and as a result the Company issued to Cerberus 7 shares of Series A-2 Preferred Stock.

    Depreciation expense related to property, plant and equipment was $2,656 and $1,175 for the three months ended March 31, 2025, and 2024 respectively.
    The Company recorded a loss from write-down of property, plant and equipment of $561 and $65 for the three months ended March 31, 2025, and 2024. The write-downs were mainly due to design changes from the Z3™-Phase 1 to Z3™-Phase 2 production in which the Phase 1 production assets could not be utilized or repurposed for Phase 2 production. Additionally, the loss from write-down of property, plant and equipment contains costs for disposal of miscellaneous equipment and tooling that cannot be repurposed.
    On June 28, 2024, the Company successfully began commercial operations on the first manufacturing line. Accordingly, the assets classified as construction in progress were reclassified to equipment, leasehold improvements, furniture and tooling as of June 28, 2024. Included in construction in progress prior to the reclassification were capitalized interest costs of $850 for the three months ended March 31, 2024. There were no capitalized interest costs recognized for the three months ended March 31, 2025.
    8. Intangible Assets
    Intangible assets consisted of various patents valued at $400, which represents the cost to acquire the patents. These patents are determined to have useful lives and are amortized into the results of operations over ten years. The Company recorded amortization expense of $10 for the three months ended March 31, 2025, and 2024, related to patents.
    The Company capitalized $172 of costs for internal-use software. The software has a useful life and is amortized into the results of operations over three years. The Company recorded amortization expense of $14 and $12 for the three months ended March 31, 2025, and 2024, respectively, related to software.
    9. Notes Receivable, Net and Variable Interest Entities (“VIEs”) Consideration
    Notes receivable, net, relates to financing the Company offered to a customer. The Company reports the notes receivable at the principal balance outstanding less an allowance for losses. The estimate of credit losses is based on historical trends, the customer’s financial condition and current economic trends. The Company charges interest at a fixed rate and calculates interest income by applying the effective rate to the outstanding principal balance.

    9. Notes Receivable, Net and Variable Interest Entities (“VIEs”) Consideration (cont.)

    The Company had notes receivable, net, of $847 outstanding as of March 31, 2025 and December 31, 2024. These amounts are included in Other assets, net and Other current assets in the accompanying Unaudited Condensed Consolidated Balance Sheets. As of March 31, 2025 and December 31, 2024, the allowance for expected credit loss related to the notes receivable amounted to $37.
    The customer to whom the Company offers financing through notes receivable is a VIE. However, the Company is not the primary beneficiary, because the Company does not have power to direct the activities of the VIE that most significantly impact the VIE’s economic performance. Therefore, the VIE is not consolidated into the Company’s Unaudited Condensed Consolidated Financial Statements. The maximum loss exposure is limited to the carrying value of notes receivable as of the balances sheet dates.
    10. Accrued Expenses
    Accrued expenses were as follows:

    11. Government Grants
    Inflation Reduction Act of 2022 (“IRA”)
    On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 into law. The IRA has significant economic incentives for both energy storage customers and manufacturers for projects placed in service after December 31, 2022. Starting in 2023, there are PTCs, which can be claimed on battery components manufactured in the U.S. and sold to U.S. or foreign customers. The tax credits available to manufacturers include a credit for ten percent of the cost incurred to make electrode active materials in addition to credits of $35 per kWh of capacity of battery cells and $10 per kWh of capacity of battery modules. These credits are cumulative, meaning that companies will be able to claim each of the available tax credits based on the battery components produced and sold through 2029, after which the PTC will begin to gradually phase down through 2032.
    The Department of Treasury and Internal Revenue Service issued final regulations in 2024 regarding the transferability of certain energy tax credits and guidance on the PTCs established by the IRA. The Company has reviewed these regulations and believes they do not have a material impact on the financial statements.

    11. Government Grants (cont.)

    Since the PTC is a refundable credit (i.e., a credit with a direct-pay option available), the PTC is outside the scope of ASC 740. Therefore, the Company accounts for the PTC under a government grant model. GAAP does not address the accounting for government grants received by a business entity that are outside the scope of ASC 740. The Company’s accounting policy is to analogize to IAS 20, Accounting for Government Grants and Disclosure of Government Assistance, under IFRS Accounting Standards. Under IAS 20, once it is reasonably assured that the entity will comply with the conditions of the grant, the grant money is recognized on a systematic basis over the periods in which the entity recognizes the related expenses or losses for which the grant money is intended to compensate. The Company recognizes grants once it is probable that both of the following conditions will be met: (1) the Company is eligible to receive the grant and (2) the Company is able to comply with the relevant conditions of the grant.
    The PTC is recorded as the applicable items become finished goods and the conditions in the preceding paragraph are met.
    The Company recognized PTC credits of $1,799 and $1,542 for the three months ended March 31, 2025 and March 31, 2024 respectively, as a reduction of cost of goods sold on the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As of March 31, 2025, and December 31, 2024, grant receivable related to the PTC in the amount of $4,082 and $2,283, respectively, is recorded in the Unaudited Condensed Consolidated Balance Sheets.

    Delayed Draw Term Loan (“DDTL”)
    As discussed in Note 3, Credit and Securities Purchase Transaction, the Company borrowed an Initial Draw of $75,000, and received $70,075, net of the 5.0% original issue discount and lender fees paid from Delayed Draw Term Loan facility on June 21, 2024. On August 29, 2024, the Company met the first tranche milestones and submitted a borrowing request under the Credit Agreement for the scheduled $30,000, and received $28,500, net of the 5.0% original issue discount. On October 31, 2024, the Company met the second tranche milestones and submitted a borrowing request under the Credit Agreement for the scheduled $65,000, and received $61,750, net of the 5.0% original issue discount. On January 24, 2025, the Company announced the achievement of all four of the third tranche milestones previously agreed upon between Eos and Cerberus. Achieving these performance milestones enabled the Company to draw an additional $40,500 and received $38,475, net of the 5.0% original issue discount on January 24, 2025, completing the scheduled fundings under the Delayed Draw Term Loan. See Note 3, Credit Agreement and Securities Purchase Transaction for additional information on this transaction.
    Each tranche under the Delayed Draw Term Loan is subject to a 5.0% original issue discount payable at the time of each draw. Borrowings under the Credit Agreement are subject to certain fees, including (i) an exit fee equal to 5.0% of the aggregate principal amount of Loans, or Revolving Loans being paid, repaid, prepaid, refinanced or replaced in a prepayment event, (ii) a make-whole payment for certain prepayments prior to March 31, 2028, as amended on November 26, 2024 and (iii) a prepayment premium for any prepayments prior to the scheduled maturity date. The Credit and Guaranty Agreement includes a Minimum Liquidity requirement under which the Company shall not permit liquidity at any time be less than $15,000 following the Company's first indebtedness incurred through the DOE LPO in December 2024.
    Milestones
    In the event the Company failed to achieve any milestones on any predetermined tranche date or the one additional milestone measurement date, the Company would not have received the specific tranche unless waived by the Lenders, and would be subject to a penalty represented by an up to 4.0% increase in the applicable percentage in the form of additional warrants or preferred shares at each missed milestone measurement date. As a result of meeting the third performance milestones, if the Company fails to achieve the remaining milestones as of the final milestone measurement date, the applicable percentage will be subject to up to a 4.0% increase for the missed milestones or an increase in the overall applicable percentage of up to 37.0%.

    13. Borrowings (cont.)
    Covenants
    On November 26, 2024, the Company amended the Credit Agreement, by and among the Company, certain of the Company’s subsidiaries as guarantors party thereto and the Lender, pursuant to which among other things, the applicability of the Consolidated Revenue and EBITDA financial covenants were deferred until December 31, 2025 and certain provisions were amended to conform with comparable provisions in the DOE Loan Facility.
    The Credit Agreement, as amended, contains the following financial covenants, including (each as defined in the Credit Agreement, as amended):
    •Minimum Consolidated EBITDA- not applicable for March 31, 2025.
    •Minimum Consolidated Revenue- not applicable for March 31, 2025.
    •Minimum Liquidity

    As of and for the three months ended March 31, 2025, the Company was in compliance with the Minimum Liquidity financial covenant.
    The facilities are subject to certain events of default which can be triggered by, among other things, (i) breach of payment obligations and other obligations and representations in the Credit Agreement or related documents, (ii) default under other debt facilities with a principal above a predetermined amount, (iii) failure to perform or comply with certain covenants in the Credit Agreement, (iv) entry into a decree or order for relief in respect of the Company or any of its subsidiaries in an involuntary case under the Bankruptcy Code of the United States or under any other debtor relief law, (v) any money judgment, writ or warrant of attachment or similar process involving in the aggregate at any time an amount in excess of $2,500, (vi) any order, judgement or decree entered against the Company or the Guarantors decreeing the dissolution or split up of such entity, (vii) the failure of the common stock to be listed on an internationally recognized stock exchange in the United States and (viii) a change of control.
    The Company elected the fair value option to account for all draws under the Delayed Draw Term Loan for operational purposes. The financial liability was initially measured at its issue-date fair value and is subsequently remeasured at fair value on a recurring basis at each reporting period date. The Company also elected the fair value option for the August Draw, October Draw and January Draw. The Initial Draw fair value, the August Draw fair value, the October Draw fair value as well as the January Draw fair value (collectively the "DDTL"), was $25,653, $12,528, $28,340 and $17,312 respectively, at issuance. As of March 31, 2025, the fair value for the DDTL was $99,433. A loss of $5,933 was recognized for the three months ended March 31, 2025. This is included in Change in fair value of debt - related party on the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
    The Company did not separately report interest expense attributable to the DDTL because such interest was included in the determination of the fair value of the Note. See Note 15, Fair Value Measurement for the assumptions used to determine the fair value the Delayed Draw Term Loan at issuance and at March 31, 2025.
    Contractual Interest Rates - Borrowings under the Credit Agreement bear interest at an annual rate equal to 15.0% per annum, subject to the following increases: (i) an additional 5.0% per annum upon the occurrence of an event of default under the Credit Agreement. The Company may elect to add accrued and unpaid interest on the loans to the principal amount of the loans (capitalized interest).
    Maturity - The DDTL is scheduled to mature on the earlier of (i) June 15, 2034 as amended on November 26, 2024, and (ii) 91 days prior to the maturity of certain of the Company’s outstanding convertible notes. See Note 3, Credit Agreement and Securities Purchase Transaction for additional information on this transaction.

    The DOE Loan Facility provides for a multi draw term loan facility under a series of at least two tranches and, if the Company elects, up to four tranches of the loan (each, a “Tranche”), subject to the achievement of certain funding conditions. Each Tranche corresponds to the production, maintenance, development, and operation of a given production line to be funded using the proceeds of such Tranche. The principal amount of each Tranche consists of a maximum principal amount designated for such Tranche in the DOE Loan Facility. Each Tranche provides the Company funding for 80% of the Eligible Project Costs. Eligible Project Costs means Project Costs that satisfy each of the following conditions: (a) DOE has determined the Project Costs to be eligible costs in accordance with Sections 609.2 and 609.10 of the Applicable Regulations; (b) the Project Costs have not been paid and are not expected to be paid any time after the First Advance Date with: (i) any federal grants, assistance, or loans (excluding the DOE Loan Facility); or (ii) other funds guaranteed by the Federal Government; (c) the Project Costs are identified in the Construction Budget; (d) the Project Costs do not constitute Cost Overruns; and (e) the Project Costs were incurred after the Eligibility Effective Date.) associated with the corresponding production line, with the Company responsible for funding the remaining 20% of the Project Costs.
    The DOE Loan Facility specifies the maximum amount subject to each tranche (Tranche 1: $101,979; Tranche 2: $117,326; Tranche 3: $71,836; and Tranche 4: $12,309), and any amounts not withdrawn under a specified tranche cannot be allocated to another tranche.
    Through March 31, 2025, the Company had drawn down $68,279 under the DOE Loan Facility, at an interest rate of 4.791%, for eligible project costs incurred through December 6, 2024. These costs are a portion of Tranche 1 of the DOE Loan Facility. Tranche 1 provides up to $101,979 for eligible costs in connection with the design, construction, installation, startup and shakedown of a battery automation line and related tools, with a projected annual production capacity of approximately 1.25 GWh ("Line 1"), as defined in the DOE Loan Facility.
    Interest expense recognized on the DOE Loan Facility is as follows:
    For the Three Months Ended March 31, 2025
    Contractual interest expense$808

    AFG Convertible Notes - Related Party
    On January 18, 2023, the Company entered into the Investment Agreement with the AFG Convertible Notes Purchasers relating to the issuance and sale to the AFG Convertible Notes Purchasers of $13,750 in aggregate principal amount of the Company’s AFG Convertible Notes. The AFG Convertible Notes bear interest at a rate of 26.5% per annum, which is entirely paid-in-kind (“PIK Interest”) semi-annually in arrears on June 30 and December 30. It is expected that the Notes will mature on June 30, 2026, subject to earlier conversion, redemption or repurchase. The AFG Convertible Notes are convertible into shares of the Company’s common stock, par value $0.0001 per share, based on an initial conversion price of approximately $1.67 per share subject to customary anti-dilution and other adjustments. The Company has the right to settle conversions in shares of common stock, cash, or any combination thereof.
    The Conversion Option includes an exercise contingency, which requires the Company to obtain stockholder approval for conversions subject to the Exchange Cap. If stockholder approval of the issuance of additional shares of Common Stock is not obtained, following commercially reasonable efforts, the Company will be required to settle the conversion in excess of the Exchange Cap in cash. Since settlement in cash may be required in absence of stockholder approval, the embedded conversion feature fails the equity classification guidance in ASC 815 and is thus precluded from being classified in equity. Therefore, the embedded conversion feature is required to be bifurcated from the AFG Convertible Notes and accounted for at fair value at each reporting date, with changes in fair value recognized on the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). The embedded derivative is presented on the Unaudited Condensed Consolidated Balance Sheets as a component of Notes payable - related party. The fair value of the embedded derivative was $27,202 and $43,124 as of March 31, 2025 and December 31, 2024, respectively.
    Interest expense recognized on the AFG Convertible Notes is as follows:

    Senior Secured Term Loan
    On July 29, 2022, the Company entered into a $100,000 Senior Secured Term Loan Credit Agreement with Atlas Credit Partners (ACP) Post Oak Credit I LLC, as administrative agent for the lenders and collateral agent for the secured parties. The Senior Secured Term Loan was scheduled to mature on the earlier of (i) July 29, 2026 and (ii) 91 days prior to the current maturity date of the 2021 Convertible Note of June 30, 2026.
    The outstanding principal balance of the Senior Secured Term Loan bore interest, at the applicable margin plus, at the Company’s election, either (i) the benchmark secured overnight financing rate (“SOFR”), which is a per annum rate equal to (y) the Adjusted Term SOFR plus 0.2616%, or (ii) the alternate base rate (“ABR”), which is a per annum rate equal to the greatest of (x) the U.S. Prime Lending Rate, (y) the NYFRB Rate (as defined in the agreement) plus 0.5% and (z) the SOFR. The applicable margin under the Credit Agreement was 8.5% per annum with respect to SOFR loans and 7.5% per annum with respect to ABR loans. Interest on the Senior Secured Term Loan accrued at a variable interest rate and interest payments were due quarterly.
    Termination of the Senior Secured Term Loan
    On June 21, 2024, the Atlas Credit Agreement, and the subsequent commitment increase agreements thereto, which provided for a $100,000 Senior Secured Term Loan Credit Agreement, were terminated pursuant to the terms of the Atlas Payoff Letter and the Insurer Letter Agreement, and all security interests and other liens granted to or held by the Atlas Lenders were terminated and released.
    In accordance with the Atlas Payoff Letter, the Company agreed to payoff the Senior Secured Term Loan for (a) approximately $11,900 (which was released from the interest escrow account maintained pursuant to the Atlas Credit Agreement and (b) $1,000 for the account of Atlas; provided that Atlas agreed to accept a participation in the Credit Agreement in lieu of such $1,000 payment, and (c) $8,000. In accordance with the Insurer Letter Agreement, the Company shall pay to the Atlas Insurers (i) on December 31, 2024, subject to the absence of certain events of default under the Credit Agreement, $3,000 and (ii) on June 30, 2025, subject to the absence of certain events of default under the Credit Agreement, $4,000.
    Absent termination, the Senior Secured Term Loan would have matured on the earlier of (i) July 29, 2026 and (ii) 91 days prior to the maturity of certain of the Company’s outstanding convertible notes. The aggregate principal amount of the Senior Secured Term Loan outstanding was $100,000 at the time of termination.

    Warrants liability
    The Company issued private placement warrants to B. Riley Financial, Inc. in conjunction with its initial public offering 2020 (“IPO warrants”). During the three months ended March 31, 2025, 50,000 IPO warrants that were issued to various counterparties became public warrants.
    In April 2023, the Company issued 16,000,000 shares of common stock and 16,000,000 private placement warrants to purchase shares of common stock. In May 2023, the Company issued another 3,601,980 shares of common stock and 3,601,980 private placement warrants to purchase shares of common stock (the “April 2023 warrants” and “May 2023 warrants”, respectively).
    In December 2023, the Company issued in a combined public offering 34,482,759 shares of common stock and 34,482,759 accompanying common warrants to purchase shares of common stock (the "December 2023 warrants"). For the three months ended March 31, 2025, 4,393,102 of the December 2023 warrants were exercised.
    The 2023 warrants do not qualify for equity classification guidance in ASC 815-40 and are measured at fair value at each reporting period.
    Warrants liability - related party
    SPA Warrant
    As discussed in Note 3, Credit Agreement and Securities Purchase Transaction, the Company issued to the Purchaser, one warrant to purchase 43,276,194 shares of common stock. The warrant has a ten-year term, a $0.01 per share exercise price, and is exercisable at the Purchaser’s discretion for cash or on a cashless basis. Upon an acceleration under the Credit Agreement, the Company could be required to purchase the warrant from the holder at an amount equal to the most recently quoted price. Following stockholder approval on September 10, 2024, the Warrant Conversion Cap increased to 49.9%. See Note 3, Credit Agreement and Securities Purchase Transaction for additional information on this transaction.
    Contingent Warrants
    Following the Initial Draw, on three separate predetermined draw dates upon the achievement of the corresponding performance milestone for each such draw date, the Company received additional funds under the Credit Agreement and issued securities under the SPA in an amount equal to the applicable percentage, up to an aggregate of 33.0% ownership limitation on a fully-diluted basis at such time the Delayed Draw Term Loan was fully drawn. Although these contingent warrants were not issued or exercisable until additional draws occurred, they meet the guidance under ASC 480 and are recognized at fair value with changes in fair value reported in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As of the balance sheet date the applicable percentage is subject to increase by 4.0% up to 37.0% on a fully diluted basis to the extent that milestones are not met on the final measurement date on April 30, 2025, in which case additional Contingent Warrants would be issuable. See Note 22, Subsequent Events, for further discussion of the applicable percentage and final measurement date.
    15. Fair Value Measurement
    Accounting standards establish a hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
    Level 1 - Quoted prices in active markets for identical assets or liabilities.
    Level 2 - Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

    15. Fair Value Measurement (cont.)
    Level 3 - Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.
    The carrying value of cash and cash equivalents, restricted cash, accounts receivable and accounts payable are considered to be representative of their fair value due to the short maturity of these instruments.
    The following tables set forth the Company's financial liabilities measured at fair values based on the fair value hierarchy, as described above. These should also be read with Note 2, Summary of Significant Accounting Policies, in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

    Each of the following recurring level 2 and level 3 instruments’ valuation model used to determine fair value is disclosed in the Company’s Annual Report on the Form 10-K for the year ended December 31, 2024.
    IPO Warrants
    The IPO warrants are valued on the basis of the quoted price of the Company’s public warrants, adjusted for insignificant difference between the public warrants and the private placement warrants.
    April 2023 warrants, May 2023 warrants and December 2023 warrants
    The April 2023 warrants, May 2023 warrants and December 2023 warrants all are valued using the Black-Scholes model at inception and on subsequent valuation dates. This model incorporates inputs such as the stock price of the Company, risk-free interest rate, volatility and time to expiration. The volatility is a significant unobservable input classified as Level 3 of the fair value hierarchy.
    The inputs used to determine the fair value of the April 2023 warrants, May 2023 warrants, and the December 2023 warrants are as follows:

    15. Fair Value Measurement (cont.)
    Accounting for instruments resulting from the Credit and Securities Purchase Transaction
    The Loan commitment assets were measured at fair value as of June 21, 2024 (see Note 3, Credit and Securities Purchase Transaction). The fair value was $76,091 at issuance calculated using the discounted cash flow model. They will not be subsequently remeasured at fair value.
    The following table summarizes instruments that were initially and subsequently measured at fair value. (see Note 3, Credit and Securities Purchase Transaction):
    InstrumentInitial measurement dateInitial Fair Value
    Initial Draw of the Delayed Draw Term Loan6/21/2024$25,653 
    SPA Warrant6/21/2024$32,903

    January Draw of the Delayed Draw Term Loan
    1/24/2025$17,312 
    The fair value of each draw of the Delayed Draw Term Loan was estimated using a discounted cash flow (“DCF”) method, based on the contractual cash flows discounted at a debt yield and considering the probability of achieving certain milestones.
    The fair value for the SPA warrant is estimated based on its intrinsic value, using the Eos common stock closing price adjusted by a discount for lack of marketability (“DLOM”), less the exercise price of $0.01 for the SPA Warrant. A DLOM was applied considering the underlying shares of the SPA Warrants are unregistered.
    The fair value of the Contingent Warrants is estimated based on the underlying Eos common stock closing price adjusted by a DLOM using Black-Scholes option pricing model, considering the probability of achieving certain milestones. A DLOM was applied considering the underlying shares of the Contingent Warrants are unregistered.
    The fair values for all the above instruments are designated as level 3 measurements as they rely on significant unobservable inputs. The significant unobservable inputs for each of these instruments are disclosed in the tables below. All other inputs used are observable.

    16. Commitments and Contingencies
    Minimum Volume Commitment
    In June 2022, the Company entered into a long-term supply agreement with a minimum volume commitment with a third party which provides services to process certain raw materials. Any purchase order issued under this supply agreement will be non-cancellable. To the extent the Company fails to order the guaranteed minimum volume defined in the contract at the end of the term, the Company is required to pay the counterparty an amount equal to the shortfall, if any, multiplied by a fee. The Company is currently negotiating a new long-term supply agreement with the counterparty. As part of the ongoing negotiations, during the fourth quarter of 2024, the Company paid the counterparty $1,250 as a shortfall penalty and transferred equipment with a net book value of approximately $600. As a result, the Company has been released of any minimum volume commitments as part of the original agreement.
    Legal Proceedings
    Class Action Complaints
    On August 1, 2023, a class action lawsuit (the “Houck Complaint”) was filed in the United States District Court of New Jersey by plaintiff William Houck (the “Houck Plaintiff”) against the Company and three individual officers: the Company’s Chief Executive Officer, its former Chief Financial Officer, and its current Chief Financial Officer (with the Company, the “Houck Defendants”). The Houck Complaint alleges that the Houck Defendants violated federal securities laws by making knowingly false or misleading statements about the Company’s contractual relationship with a customer and about the size of the Company’s order backlog and commercial pipeline. On November 8, 2024, the District Court granted the renewed motion to dismiss filed by the Houck Defendants. On March 13, 2025, the District Court entered the Final Judgment and Order of Dismissal.
    On November 5, 2024, a shareholder derivative lawsuit (the “Hyung Complaint”) was filed in the United States District Court of the District of New Jersey by plaintiff Jung Jae Hyung (the “Hyung Plaintiff”) against certain defendants including the Company’s current Chief Executive Officer, the Company’s current Chief Financial Officer, and five of the Company’s current Directors and one former Director (the “Hyung Defendants”). The Hyung Complaint alleges that the Hyung Defendants breached their fiduciary duties to the Company by allowing the Company to make knowingly false or misleading statements about the Company’s contractual relationship with a customer and about the size of the Company’s order backlog and commercial pipeline. The Company intends to vigorously contest this matter.

    17. Stock-Based Compensation
    Stock-based compensation expense included in the Unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) was as follows:

    The stock compensation expense has been recorded in cost of goods sold, research and development expenses and selling, general and administrative expenses.
    Restricted Stock Units (“RSU”)
    As of March 31, 2025, there was $24,150 of unrecognized compensation expense attributable to unvested RSUs, expected to be recognized over a weighted-average remaining vesting period of 2.2 years.
    Performance-Based Restricted Stock Units (“PRSU”)
    During the third quarter of 2024, the Company granted contingent shares to select key executives that may be earned based on the Company’s total shareholder return (“TSR”) over a two and three-year period following the grant date. TSR awards are paid out in stock at the end of the vesting period based on the Company’s stock performance. The performance is measured by determining the percentile rank of the total shareholder return of the Company’s common stock relative to the TSR of the Russell 2000 index peer group for the two and three-year period following the grant date. This peer group includes the entire Russell 2000 index as it existed at the beginning of the performance period, excluding any companies that were removed from the index during the performance period. The payment of awards following the two and three-year award period is based on performance achieved in accordance with the scale set forth in the plan agreement and may range from 0% to 200% of the initial grant. The fair value of the TSR awards is estimated using a Monte Carlo simulation in an option pricing framework.
    The following summarizes the key assumptions used to estimate the fair value of the TSR awards that were granted, and the resulting weighted average grant date fair value.

    17. Stock-Based Compensation (cont.)
    During the third quarter of 2024, the Company also granted shares contingent upon the achievement of certain performance milestones related to the Credit Agreement that may be earned over the performance period following the grant date. The contingent share awards (“Milestone PRSU”) are paid out in stock at the end of the vesting period based on the Company’s achievement of the performance milestones.
    As of March 31, 2025, there was $3,821 of unrecognized compensation expense attributable to unvested PRSUs, expected to be recognized over a weighted-average remaining vesting period of 1.2 years.
    18. Income Taxes
    Income tax expense was $5 and $25 for the three months ended March 31, 2025 and 2024, respectively, related to taxable earnings from foreign operations. The 2024 expense also includes state margin tax adjustments. The income tax expense differs from the amount computed by applying the statutory U.S. federal income tax rate of 21% to the loss before income taxes. This is due to fair value adjustments - debt and warrants, derecognition of loan commitment asset, foreign operations and pre-tax losses for which no tax benefit can be recognized for U.S. income tax purposes.
    The Company estimates and applies the annual effective tax rate to its ordinary earnings each interim period. Any significant unusual or infrequent items are not included in the estimation of the annual effective tax rate; instead, these items and their related income tax expense are separately stated in the interim period in which they occur. The quarterly estimate of the annual effective tax rate and related tax expense is subject to variation due to a multitude of factors, including, but are not limited to, the inability to accurately predict the Company’s pre-tax and taxable income and loss.
    At each balance sheet date, management assesses the likelihood that the Company will be able to realize its deferred tax assets. Management considered all available positive and negative evidence in assessing the need for a valuation allowance. The realization of deferred tax assets depends on the generation of sufficient taxable income of the appropriate character and in the appropriate taxing jurisdiction during the future periods in which the related temporary differences become deductible. Management has determined that it is unlikely that the Company will be able to utilize its U.S. deferred tax assets at March 31, 2025 and December 31, 2024 due to cumulative losses. Therefore, the Company has a valuation allowance against its net U.S. deferred tax assets.
    As of March 31, 2025 and December 31, 2024, the Company has unrecognized tax benefits associated with uncertain tax positions that, if recognized, would not affect the effective tax rate on income from continuing operations. The Company is currently under examination by the IRS related to tax year 2022. The Company is not under examination by any other taxing jurisdictions and none of the unrecognized tax benefits are expected to reverse within the next 12 months.
    The Company files income tax returns in U.S. federal and various state jurisdictions, as well as in Italy and India. The open tax years for federal returns are 2021 and forward and open tax years for state returns are generally 2019 and forward. In addition, net operating losses generated in closed years and utilized in open years are subject to adjustment by the tax authorities.
    19. Shareholders’ Deficit
    Preferred Stock
    The Company is authorized to issue 1,000,000 shares of preferred stock with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s Board of Directors. The preferred stock has a par value of $0.0001 As of March 31, 2025 and December 31, 2024, there were no shares of preferred stock issued or outstanding.

    19. Shareholders’ Deficit (cont.)
    Common Stock
    The Company is authorized to issue 600,000,000 shares of common stock at $0.0001 par value as of March 31, 2025. The holders of the Company’s common stock are entitled to one vote for each share held. At March 31, 2025 and December 31, 2024, there were 227,049,683 and 221,791,205 shares of common stock issued and outstanding, respectively.
    Treasury Stock
    The Company recorded treasury stock of $488 and $308 for the three months ended March 31, 2025 and 2024, for shares withheld from employees to cover the payroll tax liability of RSUs vested. The treasury stock was immediately retired.
    Public Warrants
    The Company sold warrants to purchase 9,075,000 shares of the Company’s common stock in a public offering on May 22, 2020 (the “Public Warrants”). Each Public Warrant entitles the holder to purchase a share of common stock at a price of $11.50 per share. There were no Public Warrants exercised during the three months ended March 31, 2025 and 2024. During the three months ended March 31, 2025, 50,000 IPO warrants that were issued to various counterparties became public warrants. As of March 31, 2025 and December 31, 2024, there were 7,102,254 and 7,052,254 public warrants outstanding for both periods, respectively.
    At-the-Market Offering Program
    The Company has a sales agreement with Cowen and Company, LLC (“Cowen”), with respect to an at-the-market offering (“ATM”) program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, having an aggregate offering price of up to $200,000 through Cowen as its sales agent and/or principal.
    During the three months ended March 31, 2024, the Company sold 7,239,982 shares raising proceeds of $7,206, net of fees paid to Cowen, at an average selling price of $1.03 per share.

    Generally, basic earnings per share (“EPS”) is computed by dividing earnings available to common shareholders by the weighted average number of shares of common stock outstanding during the period. The SPA Warrant, Preferred Series B and 2023 Warrants are participating securities that do not have the obligation to share in the losses of the Company. Therefore, the more dilutive of the “if-converted” and “two-class” method must be applied when calculating EPS for the common shares.

    20. Earnings Per Share (cont.)
    Management has elected to recognize changes in the redemption value of the Series B Preferred Stock. At each balance sheet date, the redemption value of the Series B Preferred Stock will be calculated, and if the redemption value is greater than the carrying value, the carrying value will be accreted to the redemption value. The remeasurement is recorded as a deemed dividend, which, in the absence of Retained earnings, reduces additional paid in capital and earnings available to common shareholders in computing basic and diluted EPS. Other potentially dilutive common shares and the related impact to earnings are considered when calculating EPS on a diluted basis.
    Since the Company incurred a net loss for the three months ended March 31, 2024, the potential dilutive shares from stock options, restricted stock units, warrants, and convertible notes were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented. Therefore, basic and diluted EPS are computed using the same number of weighted-average shares for the three months ended March 31, 2024. The following potentially dilutive shares were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive for the three months ended March 31, 2024:

    21. Segment Reporting
    The Company’s chief operating decision-maker (“CODM”) is its Chief Executive Officer and President. Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the CODM in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one operating and one reportable segment.
    The Company designs, develops, manufactures, and markets innovative zinc-based energy storage solutions for utility-scale, microgrid and commercial & industrial (C&I) applications. The Company operates and holds long-lived assets in a single geographical region, with nearly all of its revenue coming from customers in the United States.
    The CODM reviews financial information on a consolidated basis and uses Gross profit (loss) and Net income (loss) to assess financial performance considering budget-to-actual variances when making key decisions on how to allocate company resources.

    22. Subsequent Events (cont.)

    On April 30, 2025, the Company entered into that certain First Amendment to Credit and Guaranty Agreement, by and among the Company, certain of the Company’s subsidiaries as guarantors thereto and the Lenders, pursuant to which, the measurement period for achieving Sales Milestone 4 (as defined in the Credit Agreement) was extended until July 31, 2025. On April 30, 2025, the Company and Cerberus mutually agreed that the Company achieved three of the four Fourth Milestone Components (as defined in the Credit Agreement) related to the Company’s materials cost, Z3 technology and automated line. No additional Preferred Stock or Warrants will be issued to Cerberus related to the three Fourth Milestone Components achieved by the Company. With this achievement, the Company has achieved, to date, a total of fifteen of the sixteen possible Milestone Components (as defined in the Credit Agreement). If the Company fails to meet Sales Milestone 4 on July 31, 2025, then the Applicable Percentage is subject to up to a final 1% increase, and as a result Cerberus would be entitled to receive Preferred Stock or Warrants aggregating to a maximum aggregate Applicable Percentage of 34% (as compared to the original maximum adjustment for all four Milestones of up to 49%), or assuming the number of the Company’s outstanding shares of common stock on a fully diluted basis does not change after April 30, 2025, Preferred Stock and Warrants with respect to an aggregate of 166,645,514 shares of common stock, including the securities already issued to Cerberus.

    MANAGEMENT’S DISCUSSION AND ANALYSIS OF
    FINANCIAL CONDITION AND RESULTS OF OPERATIONS
    The following discussion should be read in conjunction with the accompanying Unaudited Condensed Consolidated Financial Statements for the three months ended March 31, 2025 and 2024 and the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, including the financial statements and notes thereto.
    Overview
    The Company offers an innovative Znyth™ technology battery energy storage system ("BESS") designed to provide the operating flexibility to manage increased grid complexity and price volatility resulting from an overall increase in renewable energy generation and a congested grid coming from an increase in electricity demand growth. The Company’s BESS utilizes a validated chemistry with accessible non-precious earth components in a durable design that is intended to deliver results in even the most extreme temperatures and conditions. The system is designed to be safe, flexible, scalable, sustainable and manufactured in the United States using raw materials primarily sourced in the United States. We believe the Company’s Z3™ battery module is the core of its innovative systems. The Z3 battery module is the only US designed and manufactured battery module that today provide utilities, independent power producers, renewables developers and C&I customers with an alternative to lithium-ion and lead-acid monopolar batteries for critical 3- to 12-hour discharge duration applications. We believe the Z3 battery will transform how utility, industrial and commercial customers store power.
    In addition to its BESS, the Company currently offers: (a) a Battery Management System (“BMS”) which provides a remote asset monitoring capability and service to track the performance and health of the Company’s BESS and to proactively identify future system performance issues through predictive analytics; (b) project management services to ensure the process of implementing the Company’s BESS are coordinated in conjunction with the customer’s overall project plans; (c) commissioning services that ensure the customer’s installation of the BESS meets the performance expected by the customer; and (d) long-term maintenance plans to maintain optimal operating performance of the Company’s systems.
    The Company’s growth strategy contemplates increasing sales of battery energy storage systems and related software and services through a direct sales team and sales channel partners. The Company’s current and target customers include utilities, project developers, independent power producers and commercial and industrial companies.
    Strategy
    The Company continues to invest in the design, development, and production of its next-generation product, the Eos Z3 battery. This new battery builds upon the same electrochemistry that has remained largely unchanged for nearly a decade. The Eos Z3 is engineered to reduce costs and weight while enhancing manufacturability and overall system performance. Compared to the previous Gen 2.3, the Z3 features a more cost-effective design with a simplified tub structure, 50% fewer cells, and 98% fewer welds per battery module. We believe that the Eos Z3 will offer customers twice the energy density per square foot, while maintaining the same level of safety and reliability as the previous generation.
    The transition to the Eos Z3 is progressing as planned, with the first fully-automated battery manufacturing line now installed and in commercial production. The Z3 uses the same chemistry, known for its ability to endure over 3 million cycles, but introduces a new mechanical design aimed at improving performance, reducing costs, and enhancing manufacturability. The Company began delivering Z3 battery modules in the third quarter of 2023. The Z3 incorporates valuable lessons learned from the past fifteen years, which the Company expects will drive efficiencies as it scales its state-of-the-art manufacturing capabilities.
    The Company believes that the simplicity, flexibility, and safety of its products are key attributes desired by the market. Moreover, the Company recognizes the competitive advantage offered by the Inflation Reduction Act, which provides production tax credits (PTC) for domestically manufactured battery components, as well as tax credits for customers involved in projects meeting domestic content requirements. The Company also plans to collaborate with a consortium of community leaders, universities, and supply chain partners to pursue funding opportunities under the Bipartisan Infrastructure Law of 2021.

    U.S. Department of Energy (“DOE”)
    On November 26, 2024, the Company entered into the DOE Loan Facility. The DOE Loan Facility is a key step in advancing the Company's Project American Made Zinc Energy ("AMAZE") and is expected to fund the expansion of Eos’ manufacturing capacity to 8 GWh by 2027 to meet the growing demand for longer duration battery energy storage systems. The DOE Loan Facility provides for up to $303.5 million in funding, including capitalized interest.
    The DOE Loan Facility provides for a multi draw term loan facility under a series of at least two and, if the Company elects, up to four tranches of the loan (each, a “Tranche”), subject to the achievement of certain funding conditions, with each Tranche corresponding to the production, maintenance and development, and operation of a given production line to be funded using the proceeds of such Tranche and the principal amount of each Tranche consisting of a maximum principal amount designated for such Tranche in the DOE Loan Facility. Each Tranche provides the Company funding for 80% of the Eligible Project Costs (as defined in the DOE Loan Facility) associated with the corresponding production line, with the Company responsible for funding the remaining 20% of the Eligible Project Costs.
    Through March 31, 2025, the Company has received funding under the DOE Loan Facility for an aggregate amount of $68.3 million, at an interest rate of 4.791% for eligible project costs incurred through December 6, 2024. These costs are a portion of Tranche 1 of the DOE Loan Facility. Tranche 1 provides up to $102.0 million for eligible costs in connection with the design, construction, installation, startup and shakedown of a battery automation line and related tools, with a projected annual production capacity of approximately 1.25 GWh ("Line 1").
    Inflation Reduction Act of 2022 (“IRA”)
    On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022 into law. The IRA has significant economic incentives for both energy storage customers and manufacturers for projects placed in service after December 31, 2022. One of the most important features of the IRA is that it offers a 10-year term tax credit, whereas historically similar industrial credits have been shorter in duration. Customers placing new energy storage facilities in service, which include our Gen 2.3 and Z3™ BESS, could qualify for an investment tax credit (“ITC”). In December 2024, the IRS and U.S. Department of the Treasury published final regulations that clarified certain investment tax credit eligibility requirements for Section 48 energy investment tax credits that were enacted as part of the IRA. The IRA offers an extra ten percent credit if the project is in an “energy community” and another ten percent credit if the project satisfies domestic content requirements. The ten percent bonus for domestic content could represent a strategic advantage for the Company resulting from the Company’s near-sourcing and Made in America strategy, and we believe that projects utilizing Eos batteries qualify for the bonus and meet safe harbor requirements. The Company is observing accelerated customer activity in 2025 as customers seek to commence construction and incur qualifying costs prior to the end of 2025 in order to secure eligibility for the current ITC safe harbor provisions, before fully transitioning to the technology-neutral Section 48E framework effective for projects initiated thereafter.
    Production Tax Credits under Internal Revenue Code 45X (“PTC”) can be claimed on battery components manufactured in the U.S. and sold to U.S. or foreign customers. These tax credits available to manufacturers include a credit for ten percent of the cost incurred to make electrode active materials in addition to credits of $35 per kWh of capacity of battery cells and $10 per kWh of capacity of battery modules. These credits are cumulative, meaning that companies will be able to claim each of the available tax credits based on the battery components produced and sold through 2029, after which the PTC will begin to gradually phase down through 2032. In April 2024, the IRS issued final regulations related to applicable tax credit transferability and direct pay provisions of the Inflation Reduction Act. The Company has reviewed these regulations and believes they do not have a material impact on the financial statements.
    Company Highlights
    •In January 2025, the Company successfully achieved all operational milestones that guaranteed the final $40.5 million under the fully funded $210.5 million Delayed Draw Term Loan ("DDTL") to further solidify its position as a leader in American energy storage systems. Successfully meeting these performance milestones will enable the Company to fuel its ongoing operations, U.S. production expansion, and the creation of an American energy storage powerhouse, without the need to raise additional capital via debt or additional equity offerings.

    •With the Delayed Draw Term Loan fully funded, combined with DOE Loan Facility's first disbursement in December 2024, Eos has a strong foundation and sufficient capital to continue implementing Project AMAZE. The Company is executing its strategy to scale production into strong customer demand for long duration energy storage. Cash from customer projects now play an important role in funding working capital and our American-made system can play a critical role in America achieving energy independence. The $210.5 million Delayed Draw Term Loan is now fully funded, driven by the Company consistently achieving key operational milestones related to the Company’s state-of-the-art manufacturing line, raw materials cost-out, Z3 technology performance improvement and orders backlog cash conversion. The Company surpassed its January raw materials cost-out target by 6% while delivering manufacturing cycle times below 10 seconds to further demonstrate continued operational efficiency and progress.
    •In March 2025, the Company announced an $8 million standalone BESS order for the Naval Base of San Diego. Fully funded by a grant from the California Energy Commission (“CEC”), this order highlights Eos’ critical role in supporting U.S. national security infrastructure with American-made energy storage.
    •In March 2025, the Company announced Nathan Kroeker’s transition from Chief Financial Officer role to become Eos' Chief Commercial Officer. In conjunction with this strategic transition, the Company has appointed Eric Javidi as its new Chief Financial Officer, bringing extensive investing, operating and organizational leadership experience in the energy and energy infrastructure spaces. Nathan's background as Chief Financial Officer gives him a unique advantage in understanding both the financial and commercial landscapes of the industry, allowing him to create customer-centric solutions that are not only impactful, but also financially sustainable.
    •In March 2025, the Company announced that Joseph Nigro, former CFO of Exelon Corporation (NADSDAQ: EXC) and CEO of Constellation Energy (then operating division of Exelon), joined the Company’s Board of Directors.

    Liquidity and Going Concern
    As a growth company in the early commercialization stage of its lifecycle, Eos is subject to inherent risks and uncertainties associated with the development of an enterprise. In this regard, substantially all of the Company’s efforts to date have been devoted to the development and manufacturing of battery energy storage systems and complementary products and services, recruitment of management and technical staff, deployment of capital to expand the Company’s operations to meet customer demand and raising capital to fund the Company’s development. However, as a result of these efforts, the Company has incurred significant losses and negative cash flows from operations since its inception and expects to continue to incur such losses and negative cash flows for the foreseeable future until such time that the Company can reach a scale of profitability to sustain its operations.
    In order to execute its development strategy, the Company has historically relied on outside capital through the issuance of equity, debt and borrowings under financing arrangements (collectively “outside capital”) to fund its cost structure. While the Company believes its recent entry into new credit facilities as discussed below has significantly improved its capital position and provides a path to sustainable operations and profitability, there can be no assurance the Company will be able to achieve such profitability or do so in a manner that does not require additional outside capital. Moreover, while the Company has historically been successful in raising outside capital, there can be no assurance the Company will be able to continue to obtain outside capital in the future or do so on terms that are acceptable to the Company.
    As disclosed in Note 3, Credit and Securities Purchase Transaction, on June 21, 2024, the Company entered into a financing transaction with CCM Denali Debt Holdings, LP, an affiliate of Cerberus Capital Management LP (herein after referred to as “Cerberus”, “Denali”, “Lender”, “Holder”). As a result of this transaction, Cerberus agreed to provide a $210.5 million secured multi-draw facility to be made in four installments (the “Delayed Draw Term Loan”) as well as a $105.0 million revolving credit facility (“Revolving Facility”), to be made available beginning June 21, 2026, at Cerberus’ sole discretion and only if the Delayed Draw Term Loan is fully funded. As of the date the accompanying Unaudited Condensed Consolidated Financial Statements were issued (the “issuance date”), the Delayed Draw Term Loan was fully funded. As part of the Credit and Securities Purchase Transaction, Cerberus received warrants and preferred stock resulting in a 33% ownership position in the Company as of the issuance date. This ownership percentage represents $814.3 Million in market capitalization based on the May 01, 2025 closing share price of the Company’s common stock.
    As disclosed in Note 13, Borrowings, on November 26, 2024, the Company successfully closed on the DOE Loan Facility, which provides the Company with up to $303.5 million in funding, including capitalized interest, subject to the achievement of certain funding conditions. The DOE Loan Facility provides for a multi draw term loan facility under a series of at least two tranches and, if the Company elects, up to four tranches, subject to the achievement of certain conditions. Each tranche corresponds to the production, maintenance and development, and operation of a given production line to be funded using the proceeds of such tranche. The DOE Loan Facility specifies the maximum amount subject to each tranche (Tranche 1: $102.0 million; Tranche 2: $117.3 million; Tranche 3: $71.8 million; and Tranche 4: $12.3 million), and any amounts which are not withdrawn under a specified tranche cannot be allocated to another tranche. Through March 31, 2025, the Company had drawn down $68.3 million under Tranche 1.
    As of the issuance date, management evaluated the significance of the following negative financial conditions in accordance with Accounting Standard Codification 205-40, Going Concern:
    •Since its inception, the Company has incurred significant losses and negative cash from operations in order to fund its development. During the three months ended March 31, 2025, the Company had net income of $15.1 million, Adjustments to reconcile net income to cash used in operations are primarily from non-cash items on the Unaudited Condensed Consolidated Statements of Cash Flows. The non-cash items totaled $60.9 million. The Company incurred negative cash flows from operations of $28.9 million and had an accumulated deficit of $1,546.6 million as of March 31, 2025.
    49

    Table of Contents
    •As of March 31, 2025, the Company had $82.6 million of unrestricted cash and cash equivalents available to fund the Company’s operations and working capital of $94.8 million.
    •On June 21, 2024, upon closing of the Credit and Securities Purchase Transaction, Cerberus funded the Company $75.0 million of the initial draw, and the Company received $71.3 million, net of the 5.0% original issue discount. On August 29, 2024, Cerberus funded the Company $30.0 million (“August Draw”), and the Company received $28.5 million, net of the 5.0% original issue discount. On November 1, 2024, Cerberus funded the Company $65 million related to the October 31, 2024 tranche (“October Draw” or “October Tranche”), and the Company received $61.8 million, net of the 5.0% original issue discount. On January 24, 2025, Cerberus funded the Company the final $40.5 million and the Company received $38.5 million, net of the 5.0% original issue discount, related to the January 31, 2025 tranche (“January 2025 Draw”). Subsequent to the January 2025 Draw, the Delayed Draw Term Loan has been fully funded.
    •Through March 31, 2025, under the DOE Loan Facility, the Company drew down $68.3 million for the eligible project cost that the Company had incurred through December 6, 2024. These costs are a portion of Tranche 1 of the DOE Loan Facility. Tranche 1 provides up to $102.0 million for eligible costs in connection with the design, construction, installation, startup and shakedown of a battery automation line and related tools. In the event the Company does not achieve certain funding milestone conditions and the DOE chooses not to continue funding, the Company would need to seek alternative sources of capital, which may not be available on favorable terms or at all.
    •The Credit and Securities Purchase Transaction and the DOE Loan Facility contain certain quarterly financial covenants, which include (a) Minimum Liquidity, (b) Minimum Consolidated EBITDA, and (c) Minimum Consolidated Revenue (collectively, the “financial covenants”). As of March 31, 2025, the only financial covenant in effect was Minimum Liquidity. As of March 31, 2025, the Company was in compliance with this covenant and non-financial covenants, and the Company expects to remain in compliance with the Minimum Liquidity covenant over the next twelve months beyond the issuance date. The Minimum Consolidated EBITDA and Minimum Consolidated Revenue financial covenants become effective beginning December 31, 2025. As of March 31, 2025, the Company expects that it may be unable to remain in compliance with the Minimum Consolidated EBITDA and Minimum Consolidated Revenue financial covenants beginning December 31, 2025, absent the Company’s ability to secure a waiver or amend the Credit and Securities Purchase Transaction and the DOE Loan Facility. The Company continues to be in regular communication with Cerberus and DOE regarding these covenants. In the event the Company is unable to comply with the financial and non-financial covenants beginning December 31, 2025, and the Company is unable to secure a waiver, Cerberus and the DOE may, at their discretion, enter into a forbearance agreement with the Company and/or exercise any and all of their existing rights and remedies, which may include, among other things, asserting their rights in the Company’s assets securing the loans. Moreover, the Company’s other lenders may exercise similar rights and remedies under the cross-default provisions of their respective borrowing agreements with the Company.
    •In the event the Company’s ongoing efforts to raise additional outside capital are unsuccessful, the Company will be unable to meet its obligations as they come due over the next twelve months beyond the issuance date. In such an event, management will be required to seek other strategic alternatives, which may include, among others, a significant curtailment in the Company’s operations, a sale of certain of the Company’s assets, a sale of the entire Company to strategic or financial investors and/or allowing the Company to become insolvent.
    These uncertainties raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared on the basis that the Company will continue to operate as a going concern, which contemplates that the Company will be able to realize assets and settle liabilities and commitments in the normal course of business for the foreseeable future. Accordingly, the accompanying Unaudited Condensed Consolidated Financial Statements do not include any adjustments that may result from the outcome of these uncertainties.
    Financing Arrangements
    The Company has historically relied on outside capital to fund its cost structure and expects this reliance to continue for the foreseeable future until the Company reaches profitability through its planned revenue generating activities. During the three months ended March 31, 2025, the Company closed on the following capital transactions:
    •In 2024, the Company secured a strategic investment of up to $315.5 million from Cerberus. The investment by Cerberus is structured as a $210.5 million Delayed Draw Term Loan to be made in four installments. On June 21, 2024 the first installment of $75.0 million was funded, and on August 29, 2024, the second draw of $30.0 million was funded, on October 31, 2024 the third draw of $65.0 million was funded, and on January 24, 2025, the final draw of $40.5 million was funded. As part of the strategic investment, a $105.0 million Revolving Facility can be made available to the Company at the Lenders’ sole discretion and only if the Delayed Draw Term Loan is fully funded.

    Capital Expenditures
    The Company expects capital expenditures and working capital requirements to increase as it seeks to execute its growth strategy, total capital expenditures for the three months ended March 31, 2025 and March 31, 2024 were $4.9 million and $4.0 million, respectively. See Note 7, Property, Plant and Equipment for further discussion.
    Discussion and Analysis of Cash Flows
    The Company relies heavily on private placement of convertible notes, term loans, equipment financing and issuance of common stock and warrants. Our short-term working capital needs are primarily related to funding of debt interest payments, repayment of debt principal, product manufacturing, research and development and general corporate expenses. The Company’s long-term working capital needs are primarily related to repayment of long-term debt obligations and capital expenses for capacity expansion and maintenance, equipment upgrades and repair of equipment.
    The following table summarizes the Company’s cash flows from operating, investing and financing activities for the periods presented.

    Critical Accounting Estimates (“CAE”)
    The Company’s Unaudited Condensed Consolidated Financial Statements are prepared in conformity with U.S. generally accepted accounting principles (U.S. GAAP). In preparing the Company’s Unaudited Condensed Consolidated Financial Statements, management makes assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. We regularly reevaluate our assumptions, judgments and estimates. The Company’s significant accounting policies are described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.
    Critical accounting estimates are those estimates that involve a significant level of estimation uncertainty and could have a material impact on our financial condition or results of operations.

    Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, have evaluated our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) under the Exchange Act as of the end of the period covered by this report. Based upon that evaluation and consistent with the evaluations previously reported in prior periods, the CEO and CFO have concluded that, as of the end of the period covered by this Report our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

    Item 1. Legal Proceedings
    From time to time, the Company may be involved in litigation relating to claims arising out of the Company’s operations.

The Houck Complaint alleges that the Houck Defendants violated federal securities laws by making knowingly false or misleading statements about the Company’s contractual relationship with a customer and about the size of the Company’s order backlog and commercial pipeline. On November 8, 2024, the District Court granted the renewed motion to dismiss filed by the Houck Defendants. On March 13, 2025, the District Court entered the Final Judgment and Order of Dismissal.

The Hyung Complaint alleges that the Hyung Defendants breached their fiduciary duties to the Company by allowing the Company to make knowingly false or misleading statements about the Company’s contractual relationship with a customer and about the size of the Company’s order backlog and commercial pipeline. The Company intends to vigorously contest this matter.

    Amendment to Cerberus Credit Agreement
    As previously disclosed, on June 21, 2024, the Company entered into a credit and guaranty agreement (the “Credit Agreement”), and was subsequently amended by that certain omnibus amendment entered into on November 26, 2024 (the “Credit Agreement Amendment”), by and among the Company, certain of the Company’s subsidiaries as guarantors party thereto, CCM Denali Debt Holdings, LP, acting through Cerberus Capital Management II, L.P. (“Cerberus”), as administrative agent and collateral agent and the lenders party thereto from time to time (the “Lenders”), pursuant to which the Lenders have provided a $210.5 million secured multi-draw facility (the “Delayed Draw Term Loan”) that was made in four installments and a $105 million revolving credit facility, to be made available at the Lenders’ sole discretion and only if the Delayed Draw Term Loan is fully funded, on terms and subject to conditions set forth in the Credit Agreement.
    On April 30, 2025, the Company entered into that certain First Amendment to Credit and Guaranty Agreement, by and among the Company, certain of the Company’s subsidiaries as guarantors thereto and the Lenders, pursuant to which, the measurement period for achieving Sales Milestone 4 (as defined in the Credit Agreement) was extended until July 31, 2025.

With this achievement, the Company has achieved, to date, a total of fifteen of the sixteen possible Milestone Components (as defined in the Credit Agreement). If the Company fails to meet Sales Milestone 4 on July 31, 2025, then the Applicable Percentage is subject to up to a final 1% increase, and as a result Cerberus would be entitled to receive Preferred Stock or Warrants aggregating to a maximum aggregate Applicable Percentage of 34% (as compared to the original maximum adjustment for all four Milestones of up to 49%), or assuming the number of the Company’s outstanding shares of common stock on a fully diluted basis does not change after April 30, 2025, Preferred Stock and Warrants with respect to an aggregate of 166,645,514 shares of common stock, including the securities already issued to Cerberus.
