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.

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.
