EDISON, N.J., May 06, 2025 (GLOBE NEWSWIRE) -- 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 first quarter ended March 31, 2025.

First Quarter Highlights

• Revenue totaled $10.5 million, a 58% increase compared to the prior year and a 44% increase compared to the prior quarter, driven by increased customer deliveries.
• Gross loss of $24.5 million, a 93-point margin improvement from the prior year, on increased production volumes and lower Z3 product costs.
• Operating expenses totaled $28.4 million, a 46% increase compared to prior year, with 26% of the total representing non-cash items. Non-cash items accounted for 48% of the increase such as stock compensation, depreciation, and loss from PP&E write-down, while the remaining 52% of the increase was driven by headcount growth across key business areas to support the Company’s scaling efforts.
• Net income attributable to shareholders of $15.1 million, largely driven by non-cash change in fair value tied to mark-to-market adjustments related to the Company’s stock price as of March 31, 2025.
• Adjusted EBITDA loss of $43.2 million, showing a 145-point margin improvement, attributable to increased customer deliveries at lower product costs partially offset by strategic headcount expansion to support the Company’s growth.
• Total cash of $111.7 million, including restricted cash, as of March 31, 2025.
• Commercial opportunity pipeline of $15.6 billion, an increase of 10% compared to prior quarter and 17% compared to March 31, 2024, with a $680.9 million orders backlog.
  

“The Eos team delivered solid operating results. We are starting to see the product cost-out benefits combined with higher manufacturing output,” said Joe Mastrangelo, Eos Chief Executive Officer. “Year-to-date, the team has already surpassed total 2024 shipments, and during Q1 the operations team set production records across all key processes showing the ability to scale operations. We continue to position the Company for long-term profitable growth and believe that American-made long duration energy storage will play a critical role in helping the country achieve energy independence.”

2025 Outlook

• For the full-year 2025, Eos continues to expect to achieve revenue between $150 million and $190 million. This projected growth is expected to be driven by increased production volume on the Company’s first state-of-the-art manufacturing line as staged sub-assembly automation comes online.
  

Recent Business Highlights

Commercial Growth
In the first quarter, Eos grew its opportunity pipeline to $15.6 billion, an increase of $1.4 billion from the prior quarter, driven by large opportunities in Puerto Rico, multiple eight-hour potential projects in CAISO, and new direct and indirect data center projects. Post quarter end, Eos signed two new memorandums of understanding (MOUs) that expand its international presence and reinforces demand for its long-duration storage solutions.

The first MOU with Trip Ventures covers approximately 400 MWh of energy storage for a utility-scale project in Puerto Rico, partially funded through the federal government. With Eos’ support, the agreement allows the customer to advance project development, with the National Environmental Policy Act (NEPA) review being the final step before the order becomes executable. This initiative aligns with Eos’ strategic focus on delivering safe, resilient, U.S.-manufactured alternatives designed to enhance grid-scale resiliency in harsh island environments prone to extreme weather and thermal risks.

Separately, Eos signed a 5 GWh MOU with Frontier Power, a leading UK-based energy developer, marking its entry into the United Kingdom and broader international markets. While not reflected in the reported pipeline as of March 31, 2025, this agreement supports Frontier’s plans to submit multiple bids utilizing Eos’ Znyth™ battery technology in the first application window of Ofgem’s new long-duration energy storage (LDES) cap and floor scheme – a novel regulatory framework designed to provide revenue certainty and accelerate the adoption of alternative, long duration technologies focusing on 8-hour discharge duration.

Cerberus Strategic Investment
The Company successfully achieved 15 out of 16 total Cerberus performance milestones with a no-penalty extension granted by Cerberus for the remaining cash receipt milestone through July 31, 2025, tied to the reduction in 2024 sales announced last November. No additional preferred stock or warrants will be issued to Cerberus at this time. Since June 2024, the Company has surpassed these milestones across four measurement periods tied to the Delayed Draw Term Loan (DDTL), highlighting strong and consistent operational execution. This performance led to the full funding of the DDTL in January in the amount of $210.5 million, supported by advancements in its first state of the art manufacturing line, material cost reduction, improvements in Z3 technology performance and backlog cash conversion. As a result of meeting these milestones, Cerberus’ maximum equity ownership in the Company is now capped at 34% of the fully diluted share count, contingent upon meeting the extension date, which is lower than the original cap of 49% at the time the investment was first announced.

Operational Capacity Expansion
The Company set manufacturing records across all key processes and delivered its highest ever quarterly revenue in the first quarter. This strong momentum has continued into the second quarter, with 2025 year-to-date shipments already surpassing the total shipments for all of 2024. To support this growth, Eos is in the process of expanding its first manufacturing line from 1.25 GWh to 2 GWh in annualized capacity by year-end, with the initial terminal sub-assembly cell having successfully passed Site Acceptance Testing. Eos expects full implementation of its subassembly automation to be complete early in the third quarter, a crucial step toward increasing throughput and reducing labor and overhead costs. The Company is also in the process of finalizing its expansion plans as it relates to subsequent lines and sites.

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 for 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 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, 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 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.
