SES AI
CPS 33Lithium-metal battery cells for drones with AI-optimized performance. NDAA-compliant manufacturing in South Korea
SES AI is an early-revenue enabling technology company pivoting from EV development services to drone batteries, ESS solutions, and AI-accelerated materials discovery. While the ~10x revenue growth to $21M in 2025 and liquidity runway into 2028 are encouraging, the company remains pre-scale with no disclosed production deployments, unproven manufacturing yields for Li-metal cells, and significant execution risk across all three business units. It offers a 'picks-and-shovels' angle for autonomous systems investors but requires substantial proof points before warranting a higher conviction rating.
Revenue grew approximately 10x from ~$2M in 2024 to $21M in 2025, with 2026 guidance of $30-35M implying 43-67% further growth
Molecular Universe Ai4Science platform has produced six materials breakthroughs now being tested by 40+ customers across EVs, drones, ESS, and consumer electronics — suggesting broad market interest
Strategic pivot to drone/UAS batteries targets a faster-adoption market than automotive EVs, with NDAA compliance positioning SES for U.S. defense procurement opportunities
UZ Energy acquisition adds ESS hardware+software capabilities enabling a potentially sticky, solutions-focused revenue model with recurring analytics/maintenance services
Strong balance sheet with management-stated liquidity into 2028 provides runway to execute the commercial transition without near-term dilution pressure
JV with Hisun providing 150,000-ton annual capacity offers potential manufacturing scale for materials commercialization without heavy capex
No named production deployments disclosed — all customer traction remains at testing/evaluation stage with unknown conversion rates to paid orders
2025 revenue was substantially driven by concluding one-time EV development services with Honda and Hyundai, making the underlying organic run-rate unclear
Li-metal battery manufacturing at production scale remains unproven — yields, safety, cycle life, and quality consistency are critical unknowns for drone/defense applications
No segment revenue breakdowns or profitability metrics disclosed, making it impossible to assess unit economics or margin trajectory across the three business units
Intense competition in advanced batteries (QuantumScape, Solid Power, CATL, etc.) and AI-materials discovery (multiple well-funded startups and incumbents) threatens differentiation
Policy and supply chain risks including NDAA compliance, tariffs, trade restrictions, and dependence on third-party manufacturing could disrupt the SE Asia expansion and defense market access
Manufacturing scale-up risk: Converting Chungju facility from EV to drone cell formats while maintaining Li-metal quality and safety standards
Revenue concentration and mix shift: 2025 revenue heavily influenced by concluding Honda/Hyundai services; unclear if ESS and drone revenue can replace this
Customer conversion risk: 40+ customers testing materials but no disclosed conversion to commercial orders or production contracts
Competitive displacement: Well-capitalized battery incumbents (CATL, Samsung SDI) and solid-state peers could outpace SES in drone/ESS markets
Regulatory and trade policy risk: NDAA compliance, tariffs, and geopolitical tensions affecting SE Asia manufacturing expansion and JV with Hisun
Cash burn trajectory: No profitability metrics disclosed; even with liquidity into 2028, sustained losses could require dilutive financing
First commercial drone cell shipments from converted Chungju facility — would validate manufacturing pivot and Li-metal production capability
Conversion of any of the 40+ materials testing customers to paid commercial agreements or licensing deals
Full-year ESS revenue contribution from UZ Energy acquisition in 2026, demonstrating recurring solutions revenue model
Securing a named U.S. defense/government UAS battery contract leveraging NDAA-compliant positioning
Announcement of Southeast Asia manufacturing capacity for drone cells, expanding production footprint
