Solid Power, Inc. (NASDAQ: SLDP) saw its stock soar 5.08% in pre-market trading on Wednesday, following the release of its third-quarter 2025 financial results and the announcement of a strategic partnership. The solid-state battery technology company delivered a mixed but generally positive report that seems to have bolstered investor confidence.

Solid Power reported a narrower-than-expected loss for Q3 2025, posting an adjusted loss of 14 cents per share, beating analysts' expectations of a 17-cent loss. While revenue fell 19.8% year-over-year to $3.73 million, missing the $5.70 million forecast, investors appeared to focus on the company's progress in technology development and strategic initiatives.

The primary catalyst for the stock's upward movement was the announcement of a Joint Evaluation Agreement with Samsung SDI and BMW to advance the development of all-solid-state batteries. This partnership is seen as a significant step towards commercialization and validation of Solid Power's technology. Additionally, the company reported that its SK On pilot cell line remains on schedule for completion by year-end, and its continuous electrolyte production pilot line is on track for commissioning in 2026.

Despite the revenue decline, Solid Power maintained a strong liquidity position with $300.4 million as of September 30, 2025. The company also revised its 2025 cash investment outlook to a range of $85 million to $95 million, reflecting its focus on operational efficiencies and cost reductions while continuing to invest in technology development. This fiscal discipline, combined with progress in its strategic objectives, appears to have resonated positively with investors, contributing to the stock's significant pre-market rise.
