Graphene stocks
Siemens AG (ETR: SIE) and energy storage manufacturer Skeleton Technologies announced on October 14, 2026, a nine--figure strategic investment round led by Siemens that values Skeleton at over $1 billion. The transaction is paired with an exclusive commercial partnership to supply graphene--based power systems to artificial intelligence data centers.
Key strategic highlights include:
- Exclusive Commercial Channel: Siemens secures exclusive global distribution rights to commercialize and integrate Skeleton's high--power supercapacitors into its electrical infrastructure portfolio for AI data--center operators and hyperscalers.
- Proprietary Curved Graphene Core: The systems utilize Skeleton's patented Curved Graphene material to handle rapid millisecond power swings and harmonics in high--load GPU clusters, cutting energy consumption by up to 40% while enhancing compute efficiency.
- U.S. Manufacturing Expansion: Supported by the financing, Skeleton plans to allocate more than $200 million toward expanding Silicon Valley R&D and establishing domestic U.S. cell and system manufacturing operations.
