It plans to license its technology and supply electrolyte materials to major battery manufacturers and automotive partners.

This summary outlines Solid Power, Inc.'s performance for the fiscal year ended December 31, 2025:

Financial Performance – Still in Investment Mode

As a development-stage company, Solid Power heavily invests in research and infrastructure before widespread commercialization. Its financials reflect this investment phase:

• Revenue: Total revenue increased modestly by 10%, rising from $10 million in 2024 to $11 million in 2025. New government contracts generated this $1 million increase, while core revenue from partner collaborations held steady at $10 million.
• Net Loss: As is typical for a company at this stage, Solid Power reported a significant net loss of $100 million in 2025, an increase from $95 million in 2024. This resulted in a loss per share of approximately $0.50 in 2025.
• Research & Development (R&D): R&D remained the largest expense, holding steady at a substantial $100 million in both 2024 and 2025. This investment fuels technology development and facility build-out.
• Selling, General & Administrative (SG&A): SG&A costs, including selling and marketing, totaled $10 million in both 2024 and 2025.
• Cost of Sales: In 2025, cost of sales reached $11 million, resulting in a gross profit of $0 for the year. This indicates that current revenues barely covered the direct costs of generating them.

Risk Factors

Investors in Solid Power face several significant risks:

• Technology Development & Commercialization Risk: Solid-state battery technology remains an emerging field. There is no guarantee Solid Power's technology will successfully scale to mass production, meet automotive performance and cost targets, or achieve widespread adoption. Manufacturing complex solid-state cells at high volumes presents significant technical and operational challenges.
• Customer Concentration: Three customers generated approximately 90% of Solid Power's total revenue in 2025, and two customers accounted for nearly all of its accounts receivable. This represents a major concern. Losing or reducing business from any of these key partners would severely impact Solid Power's financial performance.
• Continuous Need for Capital & Dilution: As a pre-revenue, R&D-intensive company, Solid Power will likely require additional future funding to continue operations and scale up. Frequent capital raises, such as the recent offering, can dilute existing share value.
• Competition: The battery technology landscape is highly competitive. Numerous companies, including other solid-state developers like QuantumScape and SES, as well as traditional battery giants, vie for market share. Solid Power must continuously innovate to maintain its competitive edge.
• Intellectual Property: Protecting its patents and proprietary technology is crucial. Any challenges to its intellectual property (IP) could undermine its competitive position.

Management's Discussion and Analysis (MD&A) Highlights

Management's discussion highlights the company's financial condition, operational results, liquidity, capital resources, and significant operational developments.

• Operational Progress: Solid Power continued refining its proprietary sulfide-based solid electrolyte material, focusing on improving performance, manufacturability, and cost-effectiveness. Its "Electrolyte Innovation Center" became fully operational in early 2025, enhancing R&D capabilities. The "Cell Safety Abuse Lab" is now fully equipped for advanced safety testing. Significant R&D spending reflects the company's commitment to achieving key technical milestones for future commercialization.
• Key Partnerships:
  • BMW of North America: Solid Power continues its joint development agreement with BMW, focusing on developing and delivering A-sample solid-state battery cells for automotive qualification. BMW also purchases electrolyte materials from Solid Power for its internal development.
  • Ford Motor Company: Ford remains a strategic investor and partner, collaborating on solid-state battery technology development for future EV applications.
  • These partnerships are critical for validating Solid Power's technology and paving the way for commercialization within the automotive industry.
• Pilot Production: Its pilot production lines for electrolyte and full-cell manufacturing are operational. They produce larger quantities of materials and cells for internal testing and partner evaluation, essential for scaling up.
• Results of Operations: New government contracts primarily drove the revenue increase, while core collaborative R&D revenue remained stable. The net loss grew due to continued high R&D investments, which management deems necessary for long-term technology development.
• Critical Accounting Policies: The filing discusses critical accounting policies, including revenue recognition, research and development expenses, and stock-based compensation. These policies involve significant management judgments and estimates.

Financial Health

Solid Power concluded 2025 with $300 million in cash, cash equivalents, and marketable securities. This healthy cash position is crucial for funding ongoing R&D and operations. The company manages its liquidity by holding a diversified investment portfolio, including U.S. Treasury securities, municipal bonds, corporate bonds, and commercial paper.

• Recent Funding: To bolster cash reserves and extend its operational runway, the company completed a Registered Direct Offering in January 2026, raising approximately $100 million in gross proceeds. This offering involved selling 20 million shares of common stock and warrants to purchase an additional 10 million shares.
• Dilution: This offering, combined with existing public and private placement warrants, means more shares could enter the market in the future. The recent offering immediately increased the outstanding share count by approximately 5%. Further warrant exercises could lead to additional dilution for existing shareholders.
• Debt: The filing does not indicate significant long-term debt. The company primarily relies on equity financing and cash from operations (currently negative) to fund its activities.

Future Outlook

Solid Power's strategy is clear: continue heavy R&D investment to advance its solid-state battery technology, achieve key performance milestones (such as energy density, cycle life, and safety targets), and progress through the rigorous automotive qualification process (A-sample, B-sample, C-sample). The company aims to transition from a development company to a materials supplier and technology licensor.

The company anticipates continued high R&D spending in 2026 as it works towards achieving these milestones and scaling up pilot production capabilities. Its success is closely tied to the continued growth of the EV market and the industry's demand for next-generation battery solutions. It actively monitors market trends and potential regulatory changes that could impact advanced battery technology adoption. The past year saw no significant changes in leadership or overall corporate strategy.

Competitive Position

Solid Power differentiates itself by focusing on a sulfide-based solid electrolyte and a unique cell design approach, aiming for compatibility with existing lithium-ion battery manufacturing processes where possible. Its strong partnerships with major automotive OEMs like BMW and Ford provide a significant advantage for validation and potential market entry. However, it faces competition from other solid-state battery developers pursuing different chemistries (e.g., oxide-based, polymer-based) and from advancements in traditional lithium-ion technology. Scaling manufacturing and achieving cost parity with existing solutions remain key competitive challenges.
