Binding Master Supply Agreement secures a 750 MWh capacity commitment with a pathway to scale up to 2 GWh of Indensity™ deployments across Germany, Austria and Switzerland through 2031

First projects under a previously executed purchase order now in construction

PITTSBURGH and FRANKFURT AM MAIN, Germany, June 17, 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 systems sourced and manufactured in the United States, and CAPAC Energy (formerly Nala Energy GmbH), a German developer and operator of battery energy storage systems, today announced a binding Master Supply Agreement establishing an exclusive partnership across Germany, Austria and Switzerland (DACH region).

The agreement expands an existing customer relationship into a long-term commercial framework extending through 2031 and establishes a 750 MWh capacity commitment with potential to scale up to 2 GWh. It also designates CAPAC Energy as Eos’ exclusive distribution partner in the DACH region. Importantly, this marks the first international commercial framework agreement for Eos’ Indensity™ positioning the company for continued expansion across key European markets.

Germany is rapidly emerging as a critical market for long-duration energy storage. The ongoing phase-out of coal-fired generation, ambitious renewable energy targets, continued solar capacity growth, and increasing grid complexity are driving demand for flexible, multi-hour storage solutions capable of balancing supply and demand. Recent regulatory developments, including updated building code privileges for grid-scale batteries, co-location reforms, and a capacity market mechanism expected to launch in 2027, are further enhancing the long-term outlook for storage deployment in the German market.

CAPAC Energy is currently advancing construction of its first Eos projects in Germany with commercial operations targeted for late 2026. This new agreement builds on that momentum by establishing a structured framework for future deployments, enabling project-by-project execution through call-off orders under the Master Supply Agreement.

“This partnership represents more than a supply agreement, it establishes Eos’ entry into a critical international market with a customer already moving projects into construction,” said Nathan Kroeker, Chief Commercial Officer of Eos. “Germany is an attractive energy storage market in Europe, and we believe Indensity is particularly well positioned to address growing demand from data centers, industrial customers and critical infrastructure where space, flexibility and reliability are increasingly important. This agreement creates a foundation for long-term growth in the region alongside a local partner.”

“This agreement establishes the framework to scale Eos technology across one of Europe’s most important storage markets,” said Benjamin Henecka, CEO and founder of CAPAC Energy. “We have moved quickly from selecting Eos technology to project construction and are now establishing a framework that supports future growth across the DACH region. As power demand grows across industry, infrastructure and data centers, we see a clear need for storage that can deliver flexibility over multiple hours and support a more resilient power system.”

The partnership also creates an opportunity to evaluate local manufacturing and assembly capabilities in the European Union. Regional production could strengthen security of supply, support development of European supply chains and contribute to skilled industrial employment in Germany and neighboring markets.

Under the Master Supply Agreement, as purchase orders are issued, they will be included in Eos’ reported backlog.

Successful startup of Battery Line 2 supports repeatable manufacturing platform, expands production capacity, and advances path toward 4 GWh annualized capacity

PITTSBURGH, June 16, 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 the start of commercial production at its Thorn Hill manufacturing facility in Marshall Township, Pennsylvania, following the successful completion of Site Acceptance Testing (SAT) for Battery Line 2.

The launch of Battery Line 2 represents a major milestone in Eos’ evolution from proving its manufacturing model to scaling it. Following the successful deployment of Line 1, the Company has now demonstrated its ability to replicate, improve, and implement automated battery production at a second facility, helping reduce execution risk associated with future manufacturing expansion.

Eos is expanding production capacity to support growing customer demand, execute against its contracted backlog, and position the Company for the next phase of growth. Simultaneously, Line 1 surpassed its full-year 2025 production in just the first 164 days of 2026. This achievement, together with the startup of the new line, establishes a proven blueprint for future capacity additions while advancing Eos toward its goal of reaching 4 GWh of annual manufacturing capacity by the end of 2026.

Demand for Eos technology continues to build across multiple applications, supported in part by Frontier Power USA’s (FPUSA) 2 GWh capacity reservation agreement. In May 2026, FPUSA signed its first transaction to acquire a 480 MWh battery project portfolio in Texas from Bimergen Energy which was followed by FPUSA’s strategic framework agreement with Stella Energy Solutions to further advance a 2 GWh pipeline built around Eos technology.

In the United Kingdom, Frontier Power Energy Holding Ltd (Frontier Power UK) acquired the rights to the Ayr and Busby projects in Scotland, which are expected to utilize approximately 2.8 GWh of Eos Z3 Indensity™ systems under an existing framework agreement that Frontier Power UK and Eos announced in April 2025. While subject to customary development milestones, project-specific agreements and closing conditions, these opportunities demonstrate the growing demand that Line 2 was built to support.

“Battery Line 2 demonstrates our ability to continuously improve as we scale,” said John Mahaz, Chief Operating Officer of Eos. “We took the lessons learned from commissioning and operating Line 1 and incorporated them directly into the design of this facility and production line. The result is a more efficient manufacturing environment with better flow and a stronger foundation for future expansion. Most importantly, it validates that our manufacturing system can be replicated and scaled with discipline.”

Battery Line 2 was designed using the operational experience and manufacturing insights gained from commissioning Line 1. The line incorporates single-piece flow architecture, enhanced process redundancy, and advanced pick-and-place gantry systems designed to improve throughput and support more efficient production at scale.

The Thorn Hill facility itself was engineered to optimize manufacturing flow and productivity. Compared to Battery Line 1, the new layout reduces raw material travel by 86% and shortens overall production line length by 40%, improving material handling, reducing complexity, and supporting higher operating efficiency.

Production operators are onsite at the Thorn Hill facility, and Line 2 has begun producing commercial batteries. The line will ramp throughout the year, with subassemblies coming online in the early third quarter and full production targeted in the fourth quarter of 2026.

Frontier Power USA is expected to be a purpose-built independent development and investment company utilizing Eos’ vertically integrated technology stack to accelerate gigawatt-scale deployment of American-made energy storage

• 2 GWh Firm Capacity Reservation Agreement: Eos entered into a 2 GWh Capacity Reservation Agreement securing dedicated manufacturing capacity for Frontier Power USA

• ~$1.5 Billion Lender-Grade Technology Performance Insurance: A 15-year non-cancellable technology performance insurance policy framework secured with Ariel Green to accelerate multi-year project bankability

• Cerberus $100 Million Commitment: Cerberus is anchoring Frontier Power USA with a $100 million equity commitment to accelerate project deployments and is extending its existing Eos lockup through year-end 2026

• Eos Investment: Eos is expected to fund its equity contribution through a pro rata rights offering targeting approximately $150 million, allowing existing shareholders to maintain proportional economic interest in Eos’ participation​​​​​​​​​​ in Frontier USA

EDISON, N.J. and NEW YORK, May 13, 2026 (GLOBE NEWSWIRE) — Eos Energy Enterprises, Inc. (NASDAQ: EOSE), America’s leading innovator in designing, manufacturing, and providing zinc-based long duration energy storage (LDES) systems sourced and manufactured in the United States, and Cerberus Capital Management, L.P. (“Cerberus”), one of the country’s largest alternative investment firms, today announced the intention to capitalize Frontier Power USA, an independent development and investment company established to build, own, and operate a diversified portfolio of long-duration battery energy storage projects deploying Eos’ proprietary zinc bromide based Z3 technology with the strategy of becoming an Independent Power Producer (IPP).

Frontier Power USA is expected to unify three core capabilities that have historically sat across multiple stakeholders: Eos’ vertically integrated technology stack, Cerberus’s institutional capital and operating experience, and a performance wrap to be provided by Ariel Green, which underwrites Z3 performance. The performance wrap underpins the structure and will allow project debt to achieve investment-grade characteristics at competitive terms. This combination is designed to compress the project lifecycle from commitment to first energy cycle and convert Eos’ opportunity pipeline or projects with secured interconnection and offtake into funded, under construction assets.

Manufacturers in capital-intensive industries, from aviation to power generation, have long used financing vehicles to accelerate customer deployment, and those platforms have generated significant value for stakeholders over time. Frontier USA is targeting to be the first application of that proven playbook to long-duration energy storage.

Accelerated Project Deployment
Eos and Frontier Power USA entered into a firm 2 GWh capacity reservation agreement, expanding Eos’ March 31, 2026 backlog. Frontier Power USA is expected to deploy this capacity across commercial and industrial applications, AI data centers, and utility-scale projects, drawing from a multi GWh project pipeline which is under active development.

Firm Technology Performance Insurance (TPI) with Ariel Green
Simplifying project bankability and accelerating asset deployment, Frontier Power USA has secured a firm Technology Performance Insurance (TPI) framework with Ariel Green, a division of Ariel Re and a leader in clean energy insurance. The framework contemplates a 15-year non-cancellable coverage, which will be sized at the project level with a multi-year total policy capacity of up to approximately $1.5 billion, written through highly rated insurance markets including syndicates at a Lloyd’s of London consortium (A+/AA-).

This framework is designed to meet the risk and underwriting standards of institutional lenders. By providing consistent, long-term performance protection, the structure enables projects to be financed on investment-grade terms, supporting longer tenors and a lower cost of capital. Alongside this policy, Frontier Power USA is evaluating two complementary debt financing paths under the TPI framework: investment-grade-rated debt placed with institutional investors and captive insurance platforms, and project-level facilities with traditional commercial bank lenders.

Anchored by Institutional Capital & Extensive Operating Experience
Cerberus Capital Management is anchoring Frontier Power USA with a $100 million equity commitment and is concurrently extending its existing Eos lock-up through year end 2026; Cerberus is expected to receive Eos warrants, as well as controlling equity in Frontier Power USA in exchange for its commitment. The funding of Cerberus’s equity commitment is subject to certain closing conditions. As a standalone entity, Frontier Power USA will separate project-level capital from the Eos corporate balance sheet, allowing Eos to focus on technology development, manufacturing, and project execution. Frontier Power USA is expected to be led by a CEO with a deep operating track record in energy storage development and project finance, supported by a dedicated origination and structuring team.

Rights Offering
To fund its equity contribution in Frontier Power USA, Eos intends to launch a rights offering targeting approximately $150 million. In the rights offering, existing Eos common shareholders, including retail investors, would receive a distribution of subscription rights to purchase Eos securities along with receiving expected warrants. These rights would be distributed based on how much Eos common stock an existing shareholder owns as of the record date for the distribution, providing the opportunity to maintain proportional economic interest in Eos’ participation in Frontier. The structure is designed to broaden access, preserve flexibility for non-participating holders through transferability, and limit incremental dilution for those who exercise. The terms of any distribution of rights have not yet been determined, and the distribution is subject to conditions including board declaration of a distribution, shareholder approval of the increase in our authorized shares and certain other consents under our existing debt agreements.

Strategic Rationale
Frontier Power USA is expected to be a first-of-its kind: A vertically integrated BESS developer and planned IPP with direct OEM access from cell to software. The company will have direct access to an OEM at the cell IP level, through module and system architecture to the proprietary software layer, creating end-to-end integration that reduces the risks in third party assembled supply chains. It’s a purpose-built independent developer and IPP working in direct partnership with Eos and an expected embedded fully-funded financing vehicle.

It is expected to be a self-reinforcing growth engine. Cash flow generated by operating projects will be systematically reinvested into the platform, funding new project origination, accelerating Eos equipment deployment, and compounding the value of the integrated technology stack.

Together, the platform is intended to:

• Establish a scalable capital platform for gigawatt-scale Eos Z3 deployment in markets where long-duration storage is uniquely positioned to address grid resiliency and load growth
• Optimize project economics through dedicated financing, expanded institutional capital access, and direct relationships with offtakes and infrastructure partners
• Enable Eos shareholders to participate alongside strategic and institutional partners in long-term project-level value creation

Management Commentary

“We believe that Frontier Power USA will bring the speed and ability to scale that the grid urgently needs, at a time when the opportunity set is being driven by energy security requirements and sustained growth in power demand from electrification and AI. By pairing the company’s execution and deployment platform with Eos’ differentiated long-duration storage technology and expanding U.S. manufacturing base, we believe this model creates a credible path to delivering storage capacity at scale. The platform is designed to translate proven technology into reliable, deployable assets that can keep pace with the system’s evolving needs.”
— Aaron Maczonis, Managing Director at Cerberus Capital Management.

“As energy storage projects scale, bridging the gap between technology innovation and associated liabilities becomes essential. This transaction through Frontier Power USA shows how TPI can play that role, supporting both bankability and repeatable platform growth across the U.S.”
— Jamie Daggett, Energy Storage Practice Lead, Ariel Green

“Frontier Power USA changes the speed of long-duration storage financing and deployment, allowing customers to have faster access to capital and deep expertise in project development. We feel confident that this will give Eos a new growth trajectory as we continue to expand manufacturing capacity. The platform pairs our integrated technology stack with institutional capital and a lender-ready performance framework that is designed to deliver what matters most: electrons to the grid.”

Mastrangelo concluded, “We believe the planned structure maintains shareholder alignment by allowing Eos investors to participate pro rata in Frontier’s Power USA’s growth via Eos ownership while ensuring project capital is governed independently and on arm’s-length commercial terms.”
— Joe Mastrangelo, Chief Executive Officer Eos Energy

Recent Business Highlights

Frontier Power USA
Eos and Cerberus today announced the formation of Frontier Power USA, an independent development and investment company established to build, own, and operate a diversified portfolio of long-duration battery energy storage projects deploying Eos’ proprietary zinc bromide Z3™ technology with the strategy of becoming an Independent Power Producer (IPP).

Frontier Power USA is expected to unify three capabilities that have historically required separate counterparties: Eos’ vertically integrated technology stack, Cerberus’ institutional capital and operating experience, and a Technology Performance Insurance (TPI) policy arranged with specialty insurer Ariel Green that wraps Z3 system performance for the benefit of project lenders.

The platform is anchored by a $100 million equity commitment from Cerberus, subject to closing conditions, alongside a targeted contribution by Eos of approximately $150 million, subject to the ability to raise funding and certain other third-party approvals. Concurrently Cerberus is extending its existing Eos lock-up through year end 2026. Frontier Power USA is also evaluating complementary debt financing paths under the TPI framework, including institutional placements targeting investment-grade ratings and project-level facilities with commercial bank lenders.

Frontier Power USA will be overseen by an independent investment committee, and transactions between Eos and Frontier Power USA will be negotiated on arm’s-length commercial terms. Frontier Power USA is targeting a multi-GWh project pipeline across data center, utility, and industrial end markets.

Commercial Growth
During the quarter, Eos expanded its commercial pipeline to $24.3 billion and ended with a $644.6 million backlog. The pipeline increased 56% year-over-year, reflecting increasing demand across energy, infrastructure, and hyperscale customers.

Subsequent to quarter end, Eos and Frontier Power USA entered into a 2 GWh firm Capacity Reservation Agreement, expanding Eos’ March 31, 2026 backlog. This agreement provides Frontier Power USA with a capacity planning mechanism to accelerate project timelines. Eos also announced a Joint Development Agreement with TURBINE-X Energy Inc. to deliver a fully integrated energy solution combining gas-fired generation with Eos’ Indensity™ battery technology. The partnership targets deployments of up to 2 GWh of storage across accelerated demand driven by high powered computing.

Capacity Expansion at Eos New Thorn Hill Facility
Eos continues to expand its manufacturing capacity with its second battery module line on schedule for initial production by the end of the second quarter. Following successful Factory Acceptance Testing at its automation supplier, the equipment has been delivered to the Thorn Hill facility, where installation and power-on activities are underway. The line is now entering debugging in preparation for Site Acceptance Testing and initial production.

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 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, 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 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.

Joint Development Agreement establishes integrated gas-fired generation and Indensity™ storage architecture to meet accelerating power demands of AI infrastructure

PITTSBURGH and HOUSTON, April 15, 2026 (GLOBE NEWSWIRE) — Eos Energy Enterprises, Inc. (NASDAQ: EOSE) (“Eos” or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS), and TURBINE‑X Energy, Inc. (“TURBINE‑X”), a developer and integrator of large-scale, behind-the-meter gas-fired power infrastructure, today announced a Joint Development Agreement (JDA) to develop and deploy private power infrastructure for AI, a new model designed to deliver firm, dispatchable energy for hyperscale data centers and other mission-critical loads on accelerated timelines.

As AI infrastructure scales, power has moved onto the critical path. Hyperscale developers increasingly require capacity on timelines measured in months, not years—a need that is not aligned with traditional grid development cycles. The Eos and TURBINE-X solution is purpose-built for this shift, integrating gas-fired generation with Eos’ Indensity™ battery architecture to deliver reliable, on-site power at the speed and scale AI infrastructure demands.

This integrated system combines simple-cycle turbine generation with high-density, fast-response energy storage, creating a fully engineerable power solution designed specifically for constrained, high-load environments such as AI campuses. With millisecond-class storage response and high energy density within a compact footprint, the platform supports both immediate power availability and the dynamic load profiles associated with AI training and inference workloads.

Commercial Pipeline and Deployment Scale
Under the JDA, TURBINE-X is targeting up to 2 GWh of Eos storage systems across a defined project pipeline over the next 36 months, with initial deployments targeted for 2027.

“Our customers need power delivered on accelerated timelines,” said Michael Warneboldt, CEO of X-Group of Companies. “By integrating our generation capabilities with Eos storage, we can deliver a fully dispatchable, engineered solution that meets the scale and reliability requirements of hyperscale infrastructure. The JDA provides the structure and accountability to move quickly and execute.”

The current pipeline includes multiple large-scale projects in active development, each designed to support multi-hundred-megawatt deployments per site, with additional opportunities under evaluation. Projects will advance under jointly defined milestones, performance criteria, and customer requirements, governed by a Development Advisory Committee established under the agreement.

A New Model for Power Infrastructure
Private power infrastructure, sometimes described as “Bring Your Own Power” (BYOP), is emerging as a new category within energy markets, as large-load customers increasingly prioritize speed, control, and reliability in how power is sourced and deployed.

By combining TURBINE-X’s experience in complex behind-the-meter gas-fired generation with Eos’ Indensity architecture, engineered for high-density deployment in space-constrained environments, the platform establishes a repeatable model for delivering large-scale power capacity independent of traditional development timelines.

Engineering, siting, and customer engagement efforts are already underway across multiple projects, reflecting a shared focus on execution and near-term delivery.

“Power is now on the critical path,” said Justin Vagnozzi, Eos SVP of Technical Sales & Commercial Operations. “This partnership establishes a new model for private power infrastructure, purpose-built for AI. TURBINE-X brings proven execution capability in gas-fired generation, and our Indensity architecture delivers more energy in less space with the response speed these environments require. We are actively developing projects and advancing a shared commercial pipeline.”

Forward-looking statements include, but are not limited to, 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 the 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 achieve the operational milestones on the delayed draw term loan; our ability to raise financing in the future; risks associated with the credit agreement with Cerberus, including risks of default, 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; 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 the 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; risks related to adverse changes in general economic conditions; 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.

PITTSBURGH, April 09, 2026 (GLOBE NEWSWIRE) — Eos Energy Enterprises, Inc. (NASDAQ: EOSE) (“Eos” or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS), today announced that it expects to report preliminary first quarter 2026 revenue of $56 – $57 million, as record shipments and manufacturing output demonstrated continued progress in the Company’s operational scaling.

Following its most recent earnings update, the Company is providing a preliminary revenue range to offer additional visibility into first quarter performance. The expected results reflect continued operational improvements and increased manufacturing consistency.

Building on fourth quarter of 2025 operational improvements, Eos delivered meaningful first quarter of 2026 gains in manufacturing performance. Targeted operational initiatives focused on supplier quality control, lean process discipline, and equipment optimization are now delivering measurable throughput, repeatability, and overall execution. Shipments remain on track with customer contractual commitments, reinforcing strong alignment between manufacturing output and project delivery timelines.

Key first quarter achievements include:

• Record quarterly shipments, increasing 17% quarter-over-quarter
• Record quarterly battery output, increasing 10.4% quarter-over-quarter
• Record quarterly bipolar output, increasing 10.6% quarter-over-quarter
• 22% sequential improvement in bi-polar automation yields, signaling increased process stability and manufacturing consistency

Strong execution drove unit shipment growth during the quarter. Quarterly revenue reflected a higher mix of DC-system projects versus AC-coupled projects which include additional equipment sales that vary by customer configuration.

Eos has also recently achieved a key milestone in the development of its second production line (“Line 2”). The Company successfully completed Factory Acceptance Testing for its second battery line. Following site acceptance testing, initial production is targeted for the end of the second quarter.

Line 2 was purpose-built to expand manufacturing capacity while increasing efficiency. Enhancements incorporated into the battery line include a single-piece flow configuration, increased process redundancy, and advanced pick-and-place gantry systems to enable faster cycle times and repeatability. Combined with the optimized Thorn Hill facility layout, these enhancements are expected to drive meaningful performance gains.

• ~86% reduction in raw material travel distance across end-to-end operations
• ~40% reduction in battery line length driven by a single-piece flow design

As demand grows and customer requirements evolve, Eos is focused on converting that demand into executed projects, reliably, and at scale. Achieving this requires more than just manufacturing capacity; it requires strong project execution from inquiry to system operation. In support of this, Eos is adding industry veterans with proven experience in delivering complex projects.

Erik Todd joined Eos as Executive Vice President, Sales, bringing more than 20 years of experience leading large-scale energy and infrastructure sales organizations where he managed a global $1B+ industrial infrastructure business. Cristi Thomas joined Eos as Senior Vice President, Projects & Delivery, with experience leading complex, infrastructure scale energy projects across development, construction, commissioning, and operations. These additions strengthen Eos’ ability to convert capacity into executed projects and deliver on customer commitments.

Eos will report its full first quarter of 2026 financial results in May.
