Eos Energy Enterprises Announces Independent Fire Testing Results For Eos Z3 Battery System And Achieves ISO 14001 Certification Eos Energy Enterprises, Inc. announced the results of independent destructive testing of its Eos Z3 battery modules. Energy Safety Response Group (ESRG), an independent energy storage safety and fire testing organization, conducted testing equivalent to large-scale fire testing (LSFT). Under the conditions tested, the modules exhibited no thermal runaway, no sustained fire, and no propagation to adjacent live modules. The 2026 edition of NFPA 855, the standard governing the installation of stationary energy storage systems, now requires large-scale fire testing to confirm that a system failure does not spread between units at specified spacing. To address these evolving requirements, Eos subjected modules to two severe abuse scenarios: direct flame impingement and overcharge. Even with active flame applied, the modules did not enter thermal runaway, did not sustain fire, and did not propagate to adjacent modules. The tests also showed no ignition of off-gas. The results reflect the inherent safety advantages of Eos’ water-based electrolyte and flame-retardant polymer architecture, which give long-duration storage a fundamentally different fire and thermal runaway risk profile than conventional chemistries. ESRG evaluated the modules under conditions more severe than those typically expected in real-world applications. High-voltage, large-scale energy storage systems carry inherent electrical risks similar to those found in any type of power plant. Testing equivalent to large-scale fire testing is essential to understanding how these systems behave under failure conditions. In such destructive testing, the Eos battery module demonstrated a distinct safety profile, with no evidence of thermal runaway or propagation, outcomes that are highly relevant for effective risk mitigation, informed project siting, and ensuring long-term asset reliability. Separately, Eos announced it has achieved ISO 14001 certification, the globally recognized standard for environmental management systems (EMS), following a comprehensive third-party evaluation. This certification confirms that Eos maintains robust environmental management practices that strengthen operational performance, risk management, and cost efficiency. The achievement reflects the maturity of Eos’ environmental practices across its operations and manufacturing facilities. ESRG’s independent test results and the ISO 14001 certification provide third-party validation of Eos’ core technology and manufacturing operations, reinforcing the differentiated safety profile of Eos’ zinc-based chemistry as Eos scales toward 4 GWh of annual production capacity across its Turtle Creek and recently commercialized Thorn Hill facilities.

Glancy Prongay Wolke & Rotter LLP Files Securities Fraud Lawsuit on Behalf of Eos Energy Enterprises Investors Glancy Prongay Wolke & Rotter LLP announced that it has filed a class action lawsuit in the United States District Court for the District of New Jersey, captioned Yung v. Eos Energy Enterprises, Inc., et al., Case No. 2:26-cv-02372, on behalf of persons and entities that purchased or otherwise acquired Eos Energy Enterprises securities between November 5, 2025 and February 26, 2026, inclusive. Plaintiff pursues claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. On February 26, 2026, Eos Energy announced fourth quarter and full year 2025 results, reporting, among other things, full year 2025 revenue of $114.2 million, falling far short of the Company’s previously issued guidance of $150 to $160 million. Management attributed these results to, in part, that battery line downtime ran well above industry norms and the ability for the automated bipolar production to hit quality targets took longer than expected. The Company further disclosed it had uncovered inefficiencies that result in longer end-to-end production times. On this news, Eos Energy’s stock price fell $4.39, or 39.4%, to close at $6.74 per share on February 26, 2026, thereby injuring investors. The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) the Company was unable to achieve the ramp in production and capacity utilization required to achieve its previously set guidance; (2) the Company’s battery line downtime was running well above industry norms, the design intent of the line, and internal forecasts; (3) the Company was experiencing delays in the ability for its automated bipolar production to hit quality targets; (4) the Company’s inadequate systems and processes prevented it from ensuring reasonably accurate guidance and that its public disclosures were timely, accurate, and complete; and (5) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.

New major risk - Shareholder dilution The company's shareholders have been substantially diluted in the past year. Increase in shares outstanding: 32% This is considered a major risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-US$246m free cash flow). Shares are highly illiquid. Negative equity (-US$1.1b). Shareholders have been substantially diluted in the past year (32% increase in shares outstanding). Minor Risk Significant insider selling over the past 3 months (Mex$7.4m sold). Buy Or Sell Opportunity • Nov 07
