Forge Nano announced the successful close of $40 million in new funding. The funding was co-led by RockCreek, a global investment firm managing more than $15 billion in assets with a strong focus on energy innovation, critical supply chains and advanced manufacturing, and Ascent Funds, a US-based global energy technology fund.

Additional participants include Top Material, Orion Infrastructure Capital and Forge Nano’s existing investors.

With this latest raise, Forge Nano’s total capital investment now exceeds $140 million, adding RockCreek to a shareholder roster that includes GM Ventures, Volkswagen, LG Technology Ventures, Hanwha, Mitsui Kinzoku, Sumitomo Corporation of Americas, Air Liquide Catalus Capital and SBI Investment.

Forge Nano operates two high-growth business units that can directly impact the United States’ advanced manufacturing competitiveness:

• US-made, high-performance lithium-ion batteries: Forge Battery, the commercial lithium-ion battery production subsidiary of Forge Nano, designs and manufactures lithium-ion cells with industry-leading energy density that incorporate critical minerals coated using Forge Nano’s Atomic Armor technology. Manufactured using a predominately US material supply chain, the company’s battery products are tailored to provide a secure supply chain and industry leading performance for defense, aerospace and specialty applications. In January 2025, Forge Battery was awarded $100 million by the US Department of Energy to expand domestic cell manufacturing at its North Carolina facility.

• Advanced semiconductor ALD capital equipment: Forge Nano’s TEPHRA platform, launched in mid-2024, is the world’s fastest single-wafer semiconductor ALD coating tool with commercial throughput for 200mm wafers. TEPHRA produces nano-coatings that can unlock chips with 40% faster processing speeds with 50% reduced power consumption, addressing the industry’s growing demand for next-gen devices, sensors, and edge AI computing. The company’s atomic layer deposition (ALD) tools are engineered and built in the US, bolstering America’s domestic semiconductor capabilities.

Forge Nano recently installed a new battery manufacturing line and a cleanroom production facility for semiconductor ALD tool production, both located at its Colorado headquarters. Forge Nano expects the $40 million investment will be utilized for further domestic manufacturing expansion, as well as to bolster its workforce to support the company’s growing network of strategic partners and customers.
