Eos Energy Enterprises Reports Second Quarter 2026 Financial Results and Tightens Full-Year Revenue Guidance

(Positive)
Tags

Eos Energy Enterprises (NASDAQ: EOSE) reported second quarter 2026 revenue of $68.8 million, up 351% year over year, driven by 207% higher cube deliveries and a large related-party project. Gross loss was $48.8 million with gross margin of -71%, an improvement of 132 percentage points year over year.

Net loss attributable to shareholders was $275.7 million, largely from fair value adjustments on liabilities. Adjusted EBITDA loss was $71.4 million. Eos ended the quarter with $364.1 million in total cash, including restricted cash, and a record $807 million backlog (3.4 GWh), up 25% sequentially, supported by orders from four new and two repeat customers.

The company tightened its full-year 2026 revenue guidance to $300–$350 million. Post quarter end, it booked a $100 million purchase order from Frontier Power USA (FPUSA) for Phase I of the Blanquilla project and announced a strategic defense partnership under the Golden Dome for America initiative. FPUSA raised approximately $263 million in gross equity proceeds, giving it access to more than $1 billion of expected deployable project capital. Eos also launched commercial production on Line 2 at its Thorn Hill facility, reporting initial battery line cycle times about 10% faster than Line 1, and is evaluating consolidating manufacturing into this site to improve efficiency and margins.

News Explained

The August 4 closing shifts a pre-existing project into FPUSA, changing where that project sits within Eos’s reported business.

FPUSA closed on August 4, 2026, and Eos contributed a pre-existing project to the joint venture, changing which entity holds and executes that project.

Eos defines a booked order as a legally binding purchase order or master supply agreement executed by both parties; it says the Redbird purchase order transferred to FPUSA at closing and became part of the parties’ 2 GWh capacity reservation agreement.

The contributed project generated $55.0 million of second-quarter revenue and represented approximately 80% of the quarter’s total revenue, so the closing also changes the ownership context for a large disclosed revenue item.

Key Terms

long-duration energy storage, gross margin, adjusted EBITDA, rights offering, +1 more
5 terms
long-duration energy storage technical
"American-made long-duration energy storage for critical defense infrastructure"
Long-duration energy storage is technology that can store large amounts of electricity for many hours to days and release it when needed, like a very large rechargeable battery that can power a neighborhood through the night or during multi-day cloudy periods. It matters to investors because it enables more reliable use of wind and solar, reduces the need for backup power plants, creates new revenue opportunities from capacity and grid services, and can change the economics of energy projects and utilities.
gross margin financial
"Gross margin was negative 71%, improving 132 percentage points year over year"
Gross margin is the difference between how much money a company makes from selling its products and how much it costs to produce them, expressed as a percentage of sales. It shows how efficiently a company is turning sales into profit before other expenses like marketing or salaries. Higher gross margin means the company keeps more money from each sale, which is a good sign of financial health.
View in glossary
adjusted EBITDA financial
"Adjusted EBITDA loss was $71.4 million"
Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.
rights offering financial
"With Eos’ Rights Offering now complete"
A rights offering is a way for a company to raise additional money by giving existing shareholders the opportunity to buy more shares at a discounted price before they are offered to the public. It’s similar to a special sale where current owners get the first chance to buy extra items at a lower cost, allowing them to increase their investment if they choose. This process matters to investors because it can affect the value of their holdings and their ability to buy new shares at favorable terms.
View in glossary
site acceptance testing technical
"Eos completed Site Acceptance Testing and commissioning"
Site acceptance testing is the final, on-location check that equipment, systems or installations perform as promised after they are delivered and set up at a facility. It matters to investors because passing this test is often required before a company can start operations, recognize revenue or meet regulatory conditions; a failed test can delay production, increase costs and push back cash flow—like taking a newly installed car for a test drive before signing off and driving it regularly.

  • Surpassed 6.5 GWh of cumulative energy discharged by Eos technology, up nearly half a gigawatt-hour over the past three months, with projects totaling more than 200 MWh of incremental energy expected to begin operations by year-end 2026
  • Tightened full-year 2026 revenue guidance to $300 million to $350 million, from the prior range of $300 million to $400 million, and is evaluating the timing of consolidating manufacturing operations into its Thorn Hill facility to drive efficiencies, enhance margins, and support long-term profitability

PITTSBURGH, Aug. 05, 2026 (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 second quarter ended June 30, 2026.

Second Quarter Highlights

  • Revenue totaled $68.8 million, a 351% year-over-year increase, driven by 207% higher cube deliveries.
  • Gross loss was $48.8 million, compared to $31.0 million in the prior-year period. Gross margin was negative 71%, improving 132 percentage points year over year and 7 percentage points sequentially. The improvement reflects increased production volumes and lower conversion costs, partially offset by temporary manufacturing underutilization as operations ramped across two facilities and higher project costs to support a growing installed base.
  • Adjusted gross loss, excluding stock-based compensation and depreciation, was $42.9 million.
  • Net loss attributable to shareholders totaled $275.7 million, primarily driven by mark-to-market fair value adjustments on certain liabilities, reflecting changes in the Company’s end-of-quarter stock price.
  • Adjusted EBITDA loss was $71.4 million, compared to an adjusted EBITDA loss of $51.6 million in the prior-year period. Adjusted EBITDA margin improved by 235 percentage points year over year and 16 percentage points sequentially, reflecting continued operational efficiencies and increased leverage on higher revenue.
  • Total cash of $364.1 million, including restricted cash, as of June 30, 2026.
  • Backlog of $807 million, representing 3.4 GWh, up 25% sequentially, with a commercial opportunity pipeline of $24.6 billion, as of June 30, 2026.

“We delivered more revenue in the first half of 2026 than in all of 2025,” said Joe Mastrangelo, Chief Executive Officer of Eos. “The market wants a U.S. supplier of long-duration energy storage that can deliver at scale. Our focus now is converting that demand into profitable growth. The decisions we are making today, including the consolidation of manufacturing into Thorn Hill, are about building a lower-cost operation that can support that demand.”

2026 Revenue Outlook

Eos is tightening its full-year 2026 revenue guidance to $300 million to $350 million, from its prior range of $300 million to $400 million. The revised outlook reflects the Company's evaluation of the timing associated with consolidating its production lines into a single manufacturing footprint in Thorn Hill. The consolidation initiative is expected to improve manufacturing efficiency, optimize capacity utilization, enhance margins, and strengthen the Company's long-term operating profile.

Recent Business Highlights

Frontier Power USA

FPUSA exceeded its initial $250 million equity target, with approximately $263 million of gross proceeds raised from Eos, Cerberus Capital Management, and Hudson Bay Capital Management. With Eos’ Rights Offering now complete, the platform has secured the equity needed to advance its next phase of growth. These commitments, including the gross proceeds of the Rights Offering, are dedicated to FPUSA and will be used to fund project development at the joint venture. FPUSA is expected to have access to more than $1 billion of deployable project capital and has established a development pipeline totaling approximately 16 GWh. Approximately 5.0 GWh of projects have been acquired, selected, or are under active diligence, including approximately 1.8 GWh that are under construction or approaching notice to proceed.

In anticipation of the formation of FPUSA, Eos generated $55.0 million of revenue in the second quarter from a pre-existing project executed using financing provided by an affiliate of Cerberus prior to the closing of the joint venture. The project contributed approximately 80% of total second quarter revenue and was contributed to FPUSA upon closing, which occurred on August 4, 2026. As of June 30, 2026, this project and FPUSA represented 49% of Eos' backlog volume.

Commercial Momentum
Commercial momentum remained strong during and after the quarter. Backlog increased to a record $807 million, up 25% sequentially and 20% year over year, driven by orders from four new customers and two repeat customers. During the quarter, Eos received the first purchase order supporting the 100 MW / 400 MWh Redbird project. Upon FPUSA closing on August 4, 2026, this purchase order was transferred to FPUSA, where it became part of the parties’ 2 GWh Capacity Reservation Agreement.

Eos also expanded its international presence through a binding Master Supply Agreement with CAPAC Energy, establishing an exclusive distribution partnership across Germany, Austria, and Switzerland with an initial 750 MWh commitment and the potential to scale to 2 GWh through 2031.

Subsequent to quarter end, Eos announced a strategic partnership with the Department of War and was awarded a contract supporting the Golden Dome for America initiative to deploy its Eos Z3™ zinc-based long-duration energy storage technology at a critical defense installation. The Company also received a $100 million purchase order from FPUSA for Phase I of the Blanquilla project. These milestones reflect continued commercial execution, expanding market opportunities, and growing demand for Eos' safe, American-made energy storage technology, further strengthening the Company's long-term growth outlook.

Launch of Commercial Production at Eos’ New Thorn Hill Facility
Eos launched commercial production on Battery Line 2 at its Thorn Hill facility in mid-June, on schedule and in line with prior expectations, expanding manufacturing capacity to support growing customer demand. The Company is currently operating one partial production shift as part of its planned ramp strategy and remains on track to reach full production capacity in the fourth quarter. During the quarter, Eos completed Site Acceptance Testing and commissioning across all sub-assembly operations, bringing the full automation online. Line 2 continues to demonstrate strong initial operational performance, with cycle times running approximately 10% faster on the battery line and 11% faster on the bipolar line compared to Line 1, reflecting continued improvements in manufacturing efficiency and throughput.

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 U.S. 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 and adjusted gross profit (loss), which are non-GAAP financial measures as defined under the rules of the SEC. These non-GAAP financial measures should be considered supplemental to, and 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 gross profit (loss) 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 our 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 its 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.
