Solid Power (SLDP) Q1 Revenue Falls, But EV Battery Milestones Keep Growth Story Alive

Solid Power, Inc. (NASDAQ:SLDP) is one of the best EV battery stocks to buy in 2026. On May 5, Solid Power, Inc. (NASDAQ:SLDP) reported its Q1 2026 financial results, stating that revenue and grant income combined came in at $3.1 million. This is an almost 50% year over year drop. Management explained that the Q1 2025 revenue had been propped up by active billing under the SK On line installation agreement. However, the agreement reached its final milestone in Q1 2026 and effectively closed out that revenue stream. Going forward, management said, the company’s revenue will shift toward electrolyte supply and new partnership arrangements.

Quarterly net loss narrowed to $13.0 million, or $0.06 per share, from $15.2 million, or $0.08 per share, in Q1 2025. This year over year improvement was driven by a larger non-cash gain from the change in fair value of warrant liabilities, management noted. Otherwise, operating loss actually widened slightly to $26.3 million from $24.0 million.

The company detailed that on the technology side, the quarter’s biggest milestone was completing site acceptance testing for the SK On pilot cell line.
