Expects first quarter 2026 revenue of $6.3 million to $6.5 million

Affirms full year 2026 revenue guidance of $30 million to $35 million

Plans to report first quarter 2026 results on April 23, 2026

SES AI Corporation ("SES AI", the "Company," "we" or "us") (NYSE:SES), a global leader in the development and manufacturing of AI-enhanced high-performance Li-Metal and Li-ion batteries, today provided a business update for the first quarter of 2026, including expected revenue for the quarter and affirmed its previously issued full year 2026 revenue guidance.

First Quarter 2026 Business Update

Based on preliminary results, the Company expects first quarter 2026 revenue to be in the range of $6.3 million to $6.5 million, above published consensus estimates. The first quarter revenue is largely due to ESS product revenue from UZ Energy, reflecting continued momentum in the Company's largest near-term revenue generating business, as well as smaller contributions from drones and subscription revenue. First quarter results also include approximately $1.5 million in revenue from orders that were previously disclosed as having been delayed from the fourth quarter of 2025 due primarily to logistics constraints.

The Company is affirming its previously issued full year 2026 revenue guidance of $30 million to $35 million, with contributions expected from all three revenue generating business units: ESS, drones, and advanced materials. SES AI continues to execute on its capex-light business model and expects to provide additional details on its full year outlook when it reports first quarter results.

Qichao Hu, Founder and CEO of SES AI, commented, "We are pleased to start 2026 with strong momentum in our ESS business. Our first quarter results are expected to come in above expectations, driven by the continued execution of UZ Energy and growing demand for our commercial and industrial energy storage solutions."

"As we look ahead to the remainder of the year, we are confident in our full year guidance and excited about the pipeline of opportunities across our three revenue generating businesses. We remain focused on financial discipline, our capex-light model, and creating value for our shareholders through commercial execution and the continued development of the Molecular Universe platform," Hu added.
