SES AI Corporation reported Q1 2026 results showing higher revenue but continuing losses as it scales its battery and AI platforms. Revenue rose to $6.7 million from $5.8 million, driven mainly by product sales from the acquired UZ Energy ESS business, while service revenue declined.
Gross profit fell to $1.2 million as product mix shifted and cost of revenue increased. Research and development expense dropped to $11.0 million from $20.5 million, reflecting lower lab and AI infrastructure costs. Net loss was $12.1 million, similar to last year. SES ended the quarter with $46.9 million in cash and cash equivalents and $130.0 million in short-term investments, after using $19.8 million in operating cash but generating $39.1 million from net investment activity.
SES AI Corporation furnished its first quarter 2026 results and announced a Chief Financial Officer transition.
