Eos Energy Enterprises, Inc. — FY 2023 Form 10-K
Reporting period: Fiscal year ended December 31, 2023; comparable figures are for FY 2022. This is an annual report, and the supplied filing text does not provide separate Q4 results.
Business context
Eos designs and manufactures zinc-based battery energy storage systems for utility, microgrid, and commercial and industrial customers. Its Z3 battery targets 3–12-hour storage applications. The company began Z3 deliveries in Q3 2023, and its first semi-automated production line entered commercial production. Eos operates one manufacturing site in Turtle Creek, Pennsylvania and reports one operating segment.
Financial performance and position

|---|---|---|
| Revenue | $16.4 million | $17.9 million |
| Cost of goods sold | $89.8 million | $153.3 million |
| Gross loss | $73.4 million | $135.3 million |
| Operating loss | $152.9 million | $221.3 million |
| Net loss | $229.5 million | $229.8 million |
| Operating cash flow | $(145.0) million | $(196.9) million |
| Investing cash flow | $(29.5) million | $(17.2) million |
| Financing cash flow | $227.9 million | $139.5 million |
| Unrestricted cash | $69.5 million | $17.1 million |
| Total debt carrying value | $203.9 million | $175.8 million |
Revenue fell 9%. Cost of goods sold declined 41%, primarily because approximately 44% fewer containers were delivered, Gen 2.3 production was reduced and Z3 production ramped. Gross margin remained deeply negative (approximately -448% versus -755% in 2022). Net loss was nearly unchanged: lower operating losses were offset in part by higher interest expense and warrant-related losses. FY 2023 included $3.3 million of Inflation Reduction Act production tax credits recorded as a reduction of cost of goods sold.
Cash used in operations improved year over year but remained substantial. Capital expenditures were $29.3 million, compared with $20.1 million in 2022. At year-end, working capital was $61.5 million; total cash, cash equivalents and restricted cash was $84.7 million, including $15.2 million of restricted cash. Total liabilities were $297.3 million, exceeding total assets of $186.5 million; shareholders’ deficit was $110.8 million. Debt principal outstanding was approximately $239.0 million, with $3.3 million classified as current.
Material changes and financing
- Net operating cash outflow decreased by $51.8 million year over year, while investing outflows rose $12.3 million, largely reflecting manufacturing expansion spending.
- Interest expense, net rose to $18.8 million from $7.9 million, principally due to a full year of term-loan interest and higher variable rates. Related-party interest expense rose to $37.5 million from $10.9 million; 2023 included issuance-related costs on convertible notes.
- The company raised capital through equity, warrants and convertible notes, including $92.9 million net proceeds from its at-the-market program and a December offering with $50.0 million gross proceeds. Common shares outstanding increased from 82.7 million to 199.1 million during 2023.
- Debt includes a $100 million senior secured term loan, $2021 convertible notes and AFG convertible notes, among other borrowings. The term loan carried a 14.15% interest rate for its fourth-quarter 2023 payment and includes a quarterly minimum-liquidity covenant.
Outlook, risks and contingencies
- Going concern: Management and the auditor report substantial doubt about the company’s ability to continue as a going concern. The company states that without additional capital it may be unable to meet obligations over the next 12 months. It expects continued losses and negative operating cash flows while scaling production.
- Funding and covenant risk: The DOE issued a conditional commitment for a loan of up to $398.6 million to fund 80% of eligible expansion costs; definitive documents, conditions and funding remain outstanding. Eos expected to meet its term-loan liquidity covenant through March 31, 2024, but said it might not remain compliant beginning June 30, 2024 without additional capital.
- Expansion plans: Project AMAZE is a planned $500 million expansion targeting 8 GWh of production capacity. The company also expects a fully automated Z3 manufacturing line to be used in 2024; execution, financing, output and cost savings are uncertain.
- Commercial concentration and execution: Two customers represented 49.9% and 45.2% of FY 2023 revenue. Scaling production, reducing unit costs, converting backlog and pipeline to deliveries, supplier availability, and competition—including lithium-ion—are material risks.
- Controls: Management concluded internal control over financial reporting and disclosure controls were ineffective at year-end due to material weaknesses, including deficiencies in the control framework, segregation of duties, journal-entry review and management review. Remediation is ongoing. The auditor did not provide an internal-control opinion.
- Legal matters: A settlement term sheet for a stockholder action against former directors provides for an $8.5 million payment, including approximately $1.0 million already paid by Eos and approximately $7.5 million expected from D&O insurance; court approval remains pending. Eos denies allegations in a separate federal securities class action concerning customer relationships, backlog and pipeline, and says it will defend the case.
- Other unusual items: The company recorded $7.2 million of property and equipment write-downs, primarily for Gen 2.3 equipment that could not be repurposed. Warrant fair-value changes and convertible-note accounting also materially affected reported results.
Most important facts for investors to verify
- Whether the DOE loan reaches definitive approval and funding, and whether the company secures other capital sufficient to fund operations and satisfy liquidity covenants.
- Actual cash burn, unrestricted liquidity, debt service requirements and covenant compliance after year-end.
- Z3 production volumes, yields, delivery timing, unit costs and progress toward the planned automated line and 8 GWh expansion.
- Customer concentration, contract backlog and pipeline conversion into recognized revenue and cash collections.
- Remediation and testing of material weaknesses, and the status and potential exposure of the securities lawsuit and settlement approval.
- Potential dilution from further equity issuance, convertible notes, stock awards and outstanding warrants.
