Solid Power, Inc. (SLDP) released an updated investor presentation outlining its strategy as a developer of sulfide-based solid electrolytes for next-generation all-solid-state batteries, supplying materials to OEMs and battery manufacturers rather than competing as a cell maker.
The company highlights a capital-light, partner-driven model with global collaborators including BMW, SK On, and Samsung SDI, supported by $419 in liquidity, a debt-free balance sheet, and a $582 market capitalization as of June 30, 2026. Pilot electrolyte capacity is 30 MT per year across two lines, with expectations to reach 75 MT annual capacity and announce a Korea-based joint venture for commercial-scale electrolyte production by year-end 2026. Longer term, Solid Power describes a roadmap toward a 2,000-plus-MT commercial electrolyte plant (equating to about 4 GWh of battery production) and an illustrative pathway to 20,000 MT supporting roughly 40 GWh, with cost per kilogram expected to decline as volume scales. Management also notes planned 2026 cash investment of $85–$100 million, Department of Energy grant support, and approximately 235 employees, emphasizing disciplined spending and external funding to advance commercialization.
CVI Investments, Inc. and Heights Capital Management, Inc. jointly report beneficial ownership of 25,218,311 shares of Solid Power, Inc. common stock through warrants. This position represents 9.9% of the company’s common stock as of June 30, 2026.

The percentage is based on 227,217,240 shares outstanding as reported in Solid Power’s Form 10-Q. Heights Capital Management acts as investment manager to CVI and may share voting and dispositive power, while both parties disclaim beneficial ownership except for their pecuniary interest.
Solid Power, Inc., a development-stage solid-state battery company, reported second-quarter 2026 revenue and grant income of a net $(0.3) million, down from $7.5 million a year earlier, mainly because of milestone timing and a $1.2 million reversal of previously recognized non-government revenue under its SK On R&D license.
Operating expenses fell to $30.0 million from $33.4 million, driven by lower direct project costs, while research and development and selling, general and administrative spending were broadly stable to higher. The net loss narrowed to $23.8 million (loss per share $0.11) from $25.3 million (loss per share $0.14), helped by higher interest income and an $2.3 million gain from remeasuring warrant liabilities.
For the first half of 2026, net loss was $36.8 million versus $40.5 million a year earlier. Liquidity strengthened, with cash, cash equivalents, and available-for-sale securities totaling $419.3 million at June 30, 2026, up from $336.5 million, largely due to a January registered direct offering that raised $121.3 million net. The company remains debt-free and is investing heavily in a continuous electrolyte production pilot line, with related construction-in-progress of $11.0 million.
Solid Power, Inc. reported second-quarter 2026 results, highlighting progress on its solid-state battery roadmap and partnerships. The company improved electrolyte performance under its joint evaluation agreement with Samsung SDI and BMW, advanced joint venture discussions for commercial-scale electrolyte production in the Republic of Korea, and kept installation of its continuous manufacturing pilot line on schedule, targeting equipment acceptance testing in the third quarter and plant validation and startup in the fourth quarter of 2026. It completed Stage 1 of ISO 9001 certification, received a milestone payment under the Line Installation Agreement with SK On, and remains on track to deliver 2026 cash investments within prior guidance of $85 to $100 million.
Financially, total revenue and grant income were ($0.3) million in the quarter, reflecting a $1.2 million reversal of previously recognized revenue due to updated milestone assumptions. Operating expenses were $30.0 million, leading to an operating loss of $30.3 million and a net loss of $23.8 million, or $0.11 per share. Liquidity remained strong, with total liquidity of $419.3 million as of June 30, 2026, including cash and cash equivalents and available-for-sale securities, and the company reported no debt.
