The DOE Loan Facility is expected to fund the expansion of manufacturing capacity to 8 GWh by 2027. The company is observing accelerated customer activity in 2025 to secure eligibility for current ITC safe harbor provisions before transitioning to the technology-neutral Section 48E framework. The company is evaluating the future impact of the One Big Beautiful Bill Act (OBBBA) but does not anticipate a material impact from its material sourcing or ownership-related provisions.

Management Comments

• "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."
• "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."
• "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."
• "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 Company believes that the simplicity, flexibility, and safety of its products are key attributes desired by the market."
• "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."
• "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."
• "DawnOS represents a new standard in American-made battery energy storage software with technical excellence and national security designed into the platform."

Industry Context

Eos Energy operates in the rapidly expanding energy storage market, driven by increasing renewable energy generation and grid complexity. The company's focus on zinc-based battery technology positions it as an alternative to traditional lithium-ion and lead-acid batteries, particularly for 3to 12-hour discharge duration applications. The Inflation Reduction Act (IRA) provides significant tailwinds for domestic manufacturers like Eos, offering production tax credits (PTCs) and investment tax credits (ITCs) for projects meeting domestic content requirements. This legislative support is crucial for Eos's 'Made in America' strategy and its Project AMAZE, aiming to scale manufacturing capacity to 8 GWh by 2027. The recent 'One Big Beautiful Bill Act' introduces new material sourcing limitations, which Eos is evaluating, highlighting the evolving regulatory landscape for clean energy technologies. The company's expansion into the UK market with Frontier Power Ltd. indicates a broader international ambition, aligning with global trends in long-duration energy storage (LDES) development.

Comparison to Industry Standards

• Eos's Z3 battery module is highlighted as 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 3to 12-hour discharge duration applications.' This positions Eos uniquely against dominant lithium-ion players like Tesla, LG Energy Solution, and CATL, particularly in the domestic market and for specific discharge durations.
• The Z3 battery is stated to offer 'twice the energy density per square foot' compared to the previous Gen 2.3, while maintaining safety and reliability. This improvement is a key competitive factor against other battery technologies and manufacturers.
• The company's Znyth chemistry is noted for its ability to 'endure over 3 million cycles,' which, if validated by independent third parties, would represent a significant durability advantage over many conventional battery technologies, including some lithium-ion chemistries that typically offer 3,000-10,000 cycles over their lifetime.
• The company's 'Made in America' strategy and qualification for IRA domestic content bonuses provide a competitive edge against foreign manufacturers, particularly in securing U.S. government and utility contracts, such as the $8 million BESS order for the Naval Base of San Diego, which aligns with national security infrastructure goals.

• No material developments or changes in the status of legal proceedings as of September 30, 2025. Management does not expect ultimate costs to resolve current claims to have a material adverse effect on consolidated financial position, results of operations, or cash flows.

Related Party Transactions

• Cerberus Capital Management LP (Cerberus, Denali, Lender, Holder) and CCM Denali Equity Holdings, LP (Purchaser) are considered related parties due to the Credit and Securities Purchase Transaction.
• Incurred manufacturing costs of $528,000 (Q3 2025) and $1,902,000 (YTD Q3 2025) and advisory fees of $249,000 (Q3 2025) and $2,740,000 (YTD Q3 2025) from four vendors affiliated with Cerberus.
• As of September 30, 2025, $146,000 of these costs were included in Accounts payable.
• AE Convert LLC, managed by Russell Stidolph (a director), is an Affiliated Purchaser of AFG Convertible Notes. The Affiliated Purchaser's AFG Convertible Notes were converted into 2,863,291 shares of Common Stock on November 4, 2025, after stockholder approval.

Stakeholder Impact

• **Shareholders**: Significant dilution from recent equity offerings and convertible note conversions. Substantial net losses and going concern warning pose significant risk to investment value. Preferred stock holders (Cerberus) have significant governance rights and anti-dilution protection.
• **Employees**: Continued investment in R&D and scaling operations suggests job stability and growth opportunities, but the going concern warning indicates potential future uncertainty if profitability is not achieved.
• **Customers**: New product launches (DawnOS) and manufacturing capacity expansion (Project AMAZE) aim to meet growing demand for energy storage solutions. IRA benefits can make Eos products more attractive due to tax credits.
• **Suppliers**: New long-term supply agreements indicate continued business, but the company's financial health and reliance on external capital could pose risks to payment terms if not managed effectively.
• **Creditors**: The company has secured substantial debt financing (DDTL, DOE Loan, Convertible Notes), but the 'going concern' warning and high debt levels indicate elevated risk. Covenants deferral provides some breathing room but also signals underlying financial challenges.

Next Steps

• Continue to scale production to meet customer demand for battery energy storage systems.
• Execute Project AMAZE to expand manufacturing capacity to 8 GWh by 2027.
• Evaluate additional guidance regarding the One Big Beautiful Bill Act (OBBBA) and its future impact on material sourcing and ownership-related provisions.
• Monitor compliance with financial covenants (Minimum Liquidity, Consolidated Revenue, and EBITDA, with the latter two deferred until March 31, 2027).
• Continue efforts to raise additional outside capital to fund operations and achieve profitability, as indicated by the going concern warning.
• Recognize revenue from remaining performance obligations, with approximately 76% expected over the next twelve months.
• Cash payment of Capitalized PIK Interest on the DOE Loan Facility commences in 2028.

Key Dates

Recommendation

Despite impressive revenue growth and successful capital raises, the company's financial position is extremely precarious. The net loss attributable to common shareholders for the nine months ended September 30, 2025, was a staggering $1.49 billion, and the accumulated deficit stands at $2.42 billion. The negative cash flow from operations continues to worsen, and management explicitly states 'substantial doubt about the Company’s ability to continue as a going concern.' While strategic initiatives and new orders are positive, they are severely overshadowed by the fundamental lack of profitability and the ongoing, significant cash burn. The high total liabilities and deepening shareholder deficit indicate a company struggling to achieve financial viability, making it a high-risk investment with significant downside potential, even with recent capital injections.
