Shares of SES AI jumped 7.9% to $0.77 on October 19 after the company said its Chungju, South Korea plant has reached one million NDAA-compliant drone battery cells per year — and that it plans to triple capacity to three million cells by mid-2027. CEO Qichao Hu called customer demand "stronger than we expected," saying that is "the sole reason" the company is accelerating expansion. The announcement lands at a critical moment for a company fighting to keep its stock exchange listing and translate technology into dollars.
• A Real Factory Milestone, but Revenue Is Still Tiny. The Chungju plant scaled from roughly 330,000 cells annually to one million — a meaningful operational achievement. Yet SES reported just $5.1 million in Q2 2026 revenue , and management acknowledged energy storage — not drones — remains the largest revenue source.
During the Q2 earnings call, the company said it expects "meaningful drone revenue to begin in the fourth quarter" and accelerate into early 2027. Until cell shipments convert to purchase orders, capacity is a promise, not profit.
• U.S. Defense Rules Are Creating a Supply Shortage SES Could Fill. The FY2026 National Defense Authorization Act bars the Pentagon from buying batteries sourced from Chinese entities.
Compliant battery options exist, but supply hasn't caught up to demand. Rival Enovix is also expanding in South Korea, doubling its own drone cell capacity by mid-2027, with identified drone and naval battery opportunities exceeding $100 million in Q2 alone. SES has a head start shipping cells today, but competition is intensifying fast.
• The Listing Clock Is Ticking. In July 2026, the NYSE warned SES that its stock had averaged below $1.00 for 30 straight trading days.
The company has six months to sustain a close at or above $1.00 with a 30-day average above that mark. At $0.77, SES is still short. The stock's wild swings — from $0.49 near its 52-week low to $1.00 just days ago — show a thin, speculative market. A reverse stock split remains a backstop, but that fixes the ticker, not the business.
• Cash Runway Buys Time, Not Certainty. SES exited Q2 with roughly $163 million in cash and short-term investments , enough to fund operations and the expansion without an immediate capital raise. Full-year 2026 revenue guidance stands at $30–$35 million. Even at the high end, the company carries a market cap of about $265 million on barely break-even gross margins — a valuation that bets heavily on drone revenue materializing at scale next year.
