Eos Energy Enterprises Reports Fourth Quarter and Full Year 2025 Financial Results; Delivers More than 7x Year-Over-Year Revenue Growth and Initiates 2026 Revenue Guidance • $58.0 million in record quarterly revenue with Q4 exceeding the first three 2025 quarters combined • Secured over $240 million with nearly 1.1 GWh of new orders in Q4 from eight customers spanning U.S. and international markets, highlighting diversified market demand • Successfully executed a $600 million senior convertible notes issuance and registered direct common stock offering, ending the year with a record cash balance of $624.6 million • Current liquidity and operational funding plan support ongoing operations and substantial doubt no longer exists about Company’s ability to continue as a going concern • Launched Indensity™, a next-generation architecture built with Spatial Intelligence that targets up to 1 GWh per acre while delivering industry-leading flexibility and safety • Initiates 2026 revenue guidance of $300 million to $400 million EDISON, N.J. – Feb. 26, 2026 - Eos Energy Enterprises, Inc. (NASDAQ: EOSE) (“Eos” or the “Company”), America’s leading innovator in designing, manufacturing, and providing zinc-based long duration energy storage (LDES) systems sourced and manufactured in the United States, today announced its financial results for the fourth quarter and full year ended December 31, 2025. Fourth Quarter Highlights • Record quarterly revenue of $58.0 million, a 90% increase compared to the prior quarter and approximately 8x year-over-year, driven by efficiency and quality improvements in multiple operations and implementation of subassembly automation. • Gross loss of $54.4 million, a 230-point margin improvement over the prior year period, driven by improved product margins. Adjusted gross loss, which excludes stock-based compensation and depreciation, was $49.1 million. • Net loss attributable to shareholders totaled $120.5 million. On a non-GAAP basis, adjusted EBITDA loss was $71.5 million compared to $44.6 million in the prior year period, a 492-point margin improvement, reflecting stronger operational performance. • Total cash of $624.6 million, including restricted cash, as of December 31, 2025. • Order backlog totaled $701.5 million, representing 2.8 GWh, up 9% sequential quarter, reflecting strong commercial momentum and growing demand. • Commercial opportunity pipeline of $23.6 billion, a 4% increase compared to prior quarter and 64% compared to December 31, 2024. Full Year 2025 Highlights • Revenue of $114.2 million, more than 7x 2024, driven by scaled production of the company’s first generation highly automated manufacturing process and a 609% increase in customer deliveries. • Gross loss of $143.8 million, improving margins by 408 points, as manufacturing volumes increased and Z3 production costs declined. Adjusted gross loss was $128.5 million. • Net loss attributable to shareholders of $969.6 million, driven primarily by $746.8 million or 77% non-cash items related to fair value accounting, capital structure optimization, and other items such as stock-based compensation and depreciation. • Adjusted EBITDA loss of $219.1 million, compared to $156.6 million in 2024, an 812-point margin improvement, driven by ongoing operational efficiencies, leverage, and cost reductions.
“2025 was a structural turning point for Eos. We accelerated production, expanded annual capacity to 2 GWh, delivered record quarterly revenue, strengthened our cash position to over $600 million, and secured more than $240 million in fourth quarter bookings across diversified markets,” said Joe Mastrangelo, Eos Chief Executive Officer. “While disappointed in not meeting revenue expectations, execution improved significantly as 2025 progressed, and we exited the year with clear operational momentum.” Mastrangelo continued, “In 2026, our focus is on disciplined scale and margin improvement — driving manufacturing efficiency, improving unit economics quarter-over-quarter, and converting our backlog into high-quality revenue. With a strengthened balance sheet and improving cost profile, we believe we are positioned to transition from accelerated growth to sustainable value creation.” 2026 Outlook • For the full year 2026, Eos expects to achieve revenue between $300 million and $400 million. Recent Business Highlights Record Operational Performance Eos exited 2025 with 2 GWh of annualized production capacity achieved through continued automation, subassembly integration, and manufacturing process optimization. Although the capacity milestone was reached 5 weeks later than initially planned, the Company accelerated operational execution throughout the second half of the year, achieving production records across all operations. While full year’s revenue was below expectations, execution accelerated significantly with record fourth quarter revenue and year- over-year shipments increasing 659%. IndensityTM Launch The Company continued to advance its technology and market positioning with the launch of Eos Indensity™, a next-generation stackable energy storage architecture engineered to deliver up to 1 GWh of storage per acre, or roughly four times the density of many incumbent battery technologies. Indensity applies Spatial Intelligence configurations to provide both horizontal and vertical site layouts, enhancing site flexibility, safety, and adaptability to meeting diverse load profiles. On an installed $/kWh basis, Indensity is designed to be cost competitive with incumbent storage technologies while delivering long- duration performance and non-flammable chemistry advantages. Commercial Growth In 2025, Eos continued to build momentum, laying the groundwork and establishing strategic commercial relationships with leading entities across the energy, infrastructure, and hyperscale sectors. The Company ended the year with a backlog of $701.5 million, booking over $240 million in new orders in the fourth quarter across 8 customers and 9 projects representing nearly 1.1 GWh of contracted volume. Demand was broad based across commercial and industrial, distributed generation portfolios, and large front of the meter utility scale projects. The 9% increase from the end of the third quarter includes shipments, new order bookings, and backlog adjustments. Strengthened Balance Sheet In the fourth quarter, the Company significantly strengthened its liquidity and capital structure through the completion of a convertible senior notes offering and a concurrent registered direct common stock offering, generating approximately $580.5 million and $458.2 million in proceeds.
Key outcomes: • Retired $200 million of the 2030 convertible notes • Reduced annual interest expense by approximately $3 million • Added approximately $474 million of new net cash • Extended all corporate debt maturities to 2030 and beyond Given the Company’s current cash position and ongoing margin improvements, management has concluded that substantial doubt regarding the Company’s ability to continue as a going concern no longer exists.

Contacts Investors: ir@eose.com Media: media@eose.com Forward Looking Statements Except for the historical information contained herein, the matters set forth in this press release are forward- looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include, but are not limited to, statements regarding our expected revenue, for the fiscal year ended December 31, 2026, our path to profitability and strategic outlook, statements regarding orders backlog and opportunity pipeline, statements regarding our expectation that we can continue to increase product volume on our state-of-the-art manufacturing line, statements regarding our future expansion and its impact on our ability to scale up operations and increase margins, statements regarding the expected impact of DawnOSTM on efficiency operating costs, and grid- coordination, statements regarding the launch of IndensityTM and our expectations for the architecture and its expected energy density, statements regarding our expectation that we can continue to strengthen our overall supply chain, statements that refer to outlook, projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions. The words "anticipate," "believe," "continue," "could," "estimate," "expect," "intends," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "would" and similar expressions may identify forward-looking statements, but the
absence of these words does not mean that a statement is not forward-looking. Forward-looking statements are based on our management’s beliefs, as well as assumptions made by, and information currently available to, them. Because such statements are based on expectations as to future financial and operating results and are not statements of fact, actual results may differ materially from those projected. Factors which may cause actual results to differ materially from current expectations include, but are not limited to: changes adversely affecting the business in which we are engaged; our ability to forecast trends accurately; our ability to generate cash, service indebtedness and incur additional indebtedness; our ability to raise financing in the future; risks associated with the credit agreement with Cerberus, including risks of default, and dilution of outstanding common stock; consequences for failure to meet milestones and contractual lockup of shares; our customers’ ability to secure project financing; the amount of final tax credits available to our customers or to Eos pursuant to the Inflation Reduction Act, including potential impacts from any repeal or modifications of the legislation; the timing and availability of future funding under the Department of Energy Loan Facility; our ability to continue to develop efficient manufacturing processes to scale and to forecast related costs and efficiencies accurately; fluctuations in our revenue and operating results; competition from existing or new competitors; our ability to convert firm order backlog and pipeline to revenue; risks associated with security breaches in our information technology systems; risks related to legal proceedings or claims; risks associated with evolving energy policies in the United States and other countries and the potential costs of regulatory compliance; risks associated with changes to the U.S. trade environment; our ability to maintain the listing of our shares of common stock on NASDAQ; our ability to grow our business and manage growth profitably, maintain relationships with customers and suppliers and retain our management and key employees; risks related to adverse changes in general economic conditions, including inflationary pressures and increased interest rates; risk from supply chain disruptions and other impacts of geopolitical conflict; changes in applicable laws or regulations; the possibility that Eos may be adversely affected by other economic, business, and/or competitive factors; other factors beyond our control; and other risks and uncertainties. The forward-looking statements contained in this press release are also subject to additional risks, uncertainties, and factors, including those more fully described in the Company’s most recent filings with the Securities and Exchange Commission, including the Company’s most recent Annual Report on Form 10-K and subsequent reports on Forms 10-Q and 8-K. Further information on potential risks that could affect actual results will be included in the subsequent periodic and current reports and other filings that the Company makes with the Securities and Exchange Commission from time to time. Moreover, the Company operates in a very competitive and rapidly changing environment, and new risks and uncertainties may emerge that could have an impact on the forward-looking statements contained in this press release. Forward-looking statements speak only as of the date they are made. Should one or more of these risks or uncertainties materialize or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Readers are cautioned not to put undue reliance on forward-looking statements, and, except as required by law, the Company assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Key Metrics Backlog. Our backlog represents the amount of revenue that we expect to realize from existing agreements with our customers for the sale of our battery energy storage systems and performance of services. The backlog is calculated by adding new orders in the current fiscal period to the backlog as of the end of the prior fiscal period and then subtracting the shipments in the current fiscal period. If the amount of an order is modified or cancelled, we adjust orders in the current period and our backlog accordingly, but do not retroactively adjust previously published backlogs. There is no comparable US-GAAP financial measure to backlog. We believe that the backlog is a useful indicator regarding the future revenue of our Company.
Pipeline. Our pipeline represents projects for which we have submitted technical proposals or non-binding quotes plus letters of intent (“LOI”) or firm commitments from customers. Pipeline does not include lead generation projects. Booked Orders. Booked orders are orders where we have legally binding agreements with a Purchase Order (“PO”), or Master Supply Agreement (“MSA”) executed by both parties. Non-GAAP Financial Measures To provide investors with additional information regarding our financial results, we have disclosed in this earnings release non-GAAP financial measures, including adjusted EBITDA, adjusted gross profit (loss), and adjusted EPS, which are non-GAAP financial measures as defined under the rules of the SEC. These non-GAAP financial measures should be considered supplemental to, not a substitute for, or superior to, the financial measures of the Company’s calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company believes adjusted EBITDA, adjusted gross profit (loss), and adjusted EPS are useful measures in evaluating its financial and operational performance distinct and apart from financing costs, certain non-cash expenses and non-operational expenses. We believe that non-GAAP financial information, when taken collectively may be helpful to our investors in assessing its operating performance. There are a number of limitations related to the use of these non- GAAP financial measures and their nearest GAAP equivalents. For example, the Company’s definitions of non-GAAP financial measures may differ from non-GAAP financial measures used by other companies. Below is a description of the non-GAAP financial information included herein as well as reconciliations to the most directly comparable GAAP measure. You should review the reconciliations below but not rely on any single financial measure to evaluate our business. Adjusted EBITDA is defined as earnings (net loss) attributable to Eos adjusted for interest expense, income tax, depreciation and amortization, non-cash stock-based compensation expense, change in fair value of debt and derivatives, debt extinguishment, and other non-cash or non-recurring items as determined by management which it does not believe to be indicative of its underlying business trends. Adjusted gross profit (loss) is defined as gross profit (loss) adjusted to exclude stock-based compensation, depreciation and amortization. Adjusted EPS is defined as GAAP net loss per common share as adjusted for non-cash stock-based compensation expense change in fair value of debt and derivatives and debt extinguishment per common share.

Eos ended 2025 with $624.6 million in total cash, including restricted cash, after a large convertible notes issuance and equity offering. Despite this liquidity, total liabilities were $1,762.517 million and shareholders’ deficit was $2,238.862 million, reflecting a highly leveraged capital structure.
What 2026 revenue guidance did Eos Energy Enterprises provide?
For 2026, Eos expects revenue between $300 million and $400 million. This guidance implies substantial growth over 2025’s $114.2 million, assuming the company converts its $701.5 million backlog and broader $23.6 billion commercial pipeline into shipments and recognized revenue.
Has the going concern risk changed for Eos Energy Enterprises?
Management now states that substantial doubt about Eos’s ability to continue as a going concern no longer exists. This conclusion follows improved liquidity, including a $600 million senior convertible notes issuance, equity capital raise, and extended debt maturities to 2030 and beyond.
What operational and commercial milestones did Eos achieve in 2025?
Eos reached 2 GWh of annualized production capacity, improved manufacturing efficiency, and launched its Indensity architecture. It closed 2025 with a $701.5 million backlog (2.8 GWh) and booked over $240 million in new Q4 orders across eight customers and nine projects.
