Solid Power - Earnings Call - Q3 2025

Executive Summary

• Operationally constructive but financially mixed: total revenue and grant income fell sequentially to $4.6M as milestone timing shifted from equipment-heavy factory tests in Q2 to labor-focused site acceptance in Q3, while operating expenses declined to $29.0M, narrowing operating loss vs Q2.
• Liquidity strengthened to $300.4M after raising $32.9M via the ATM program; cash and cash equivalents rose to $47.3M as of 9/30/25.
• Strategic momentum: Solid Power announced a Joint Evaluation Agreement with Samsung SDI and BMW to advance all-solid-state batteries; SK On pilot line site acceptance testing remained on schedule for year-end completion.
• Guidance: 2025 cash investment outlook reduced to $85–$95M from prior expectations (prior range not previously disclosed in earnings materials), reflecting cost discipline while continuing to fund electrolyte and pilot-line progress.
• Estimate context: S&P Global consensus for Q3 2025 EPS and revenue was not available for SLDP at this time, so beat/miss vs Street cannot be assessed (S&P Global data unavailable).

What Went Well and What Went Wrong

What Went Well

• Strategic partnerships progressed: Joint Evaluation Agreement with Samsung SDI and BMW validates technology and aims to develop cells for next-gen evaluation vehicles; management called it a “meaningful advancement” toward commercialization.
• Execution milestones: SK On pilot line reached site acceptance testing, tracking for completion by year-end; electrolyte pilot line detailed design continued, with commissioning on track for 2026.
• Strengthened liquidity: Total liquidity increased to $300.4M, supported by $32.9M of ATM proceeds in Q3, enhancing funding for development while lowering 2025 cash investment guidance.

What Went Wrong

• Sequential revenue decline: Total revenue and grant income decreased to $4.6M from $7.5M in Q2 due to milestone mix shift (Q2 factory acceptance testing vs. Q3 labor-focused site acceptance); revenue recognized was primarily from SK On and government contracts.
• Continued losses: Net loss widened slightly to $(25.9)M vs. $(25.3)M in Q2, with basic/diluted loss per share at $(0.14), highlighting ongoing R&D-stage cost structure relative to limited revenue streams.
• Non-operating volatility: Change in fair value of warrant liabilities swung to a $(3.5)M expense in Q3 from a $1.6M gain in Q2, contributing to a negative non-operating result in Q3.

John Van Scoter (CEO and President)

Thank you, Charlie, and thank you all for joining us today. I am pleased to provide an update on our 2025 operational goals since our last earnings call. First, we recently announced a strategic collaboration with Samsung SDI and BMW under a joint evaluation agreement. We believe this collaboration represents a vote of confidence in our technology and the potential of solid-state batteries. Under this arrangement, Solid Power will supply sulfide-based solid electrolyte to Samsung SDI, which Samsung SDI will integrate into separator and/or catholyte and use to build cells, in each case subject to achievement of technical requirements. These cells will be evaluated based on performance parameters and requirements to be agreed between Samsung SDI and BMW Group. Ultimately, Solid Power, Samsung SDI, and BMW aim to develop and supply all solid-state battery cells for integration into a next generation of evaluation vehicles.

Together with Samsung SDI and BMW, we look forward to driving innovation in all solid-state battery technology. In addition, we believe this agreement underscores our electrolyte sampling efforts and our focus on identifying long-term customers. This quarter, we continue to execute on our agreements SK On. we conducted site acceptance testing of SK On pilot line, which remains on target for completion by the end of this year and is another key milestone under our line installation agreement SK On. during the quarter, we also made progress on our electrolyte development roadmap. We continued detailed design work for the planned installation of a continuous manufacturing pilot line for sulfide electrolyte production at SP2. We expect detailed design to be substantially complete later this year, with commissioning on track for 2026.

With that, I'll turn it over to Linda to review our financial results and provide an update on our progress towards achieving our financial discipline goal. Linda.

Linda Heller (CFO)

Thank you, John. I'll start with Q3 and year-to-date results, beginning with revenue. During the third quarter of 2025, we generated revenue of $4.6 million compared to our Q2 2025 revenue of $7.5 million. Revenue recognized this quarter was driven primarily by SK On agreements as well as our government contracts. This brings revenue year-to-date to $18.1 million and an increase of $2.4 million over the same period in 2024. Operating expenses for the third quarter were $29 million, a decrease of $4.4 million compared to our second quarter of 2025 at $33.4 million. The reduction in expenses for the third quarter was primarily due to the nature of the work performed under SK On agreement. The third quarter was labor-focused in preparation for site acceptance testing, whereas the second quarter included significant equipment purchases for factory acceptance testing.

Operating loss year-to-date was $74.3 million, and year-to-date net loss was $66.4 million or $0.37 per share. Capital expenditures totaled $0.6 million, primarily representing costs for the construction of our continuous electrolyte production pilot line. Turning to our balance sheet and liquidity during the quarter, our cash used for operations and capital expenditures was $14.9 million. This brings our total year-to-date cash investment to $61.2 million. Total liquidity increased to $300.4 million as of September 30th, 2025. This was primarily driven by proceeds from our at-the-market offering program as well as cash received from our government contracts. In addition, contract assets and contract receivables totaled $7.2 million, and total current liabilities were $16.6 million. During Q3, we remained fiscally disciplined, focused on realizing efficiencies and reducing operating costs while driving technology development and innovation.

As a result of these efforts, we are revising our expected cash investment to $85 million-$95 million in 2025. I will now turn it back to John for some final thoughts.

John Van Scoter (CEO and President)
