Ingevity Corporation announced that it has secured exclusive manufacturing rights to CHASM Advanced Materials’ patented NTeC®‑E carbon‑nanotube (CNT) additive for battery applications in North America and selected European markets. The license, signed on November 11, 2025, builds on a joint development agreement from February 2024 and gives Ingevity the sole authority to produce the technology in the region.
The NTeC®‑E additive has been validated in Ingevity’s own battery laboratories, by original equipment manufacturers, and through third‑party testing. Results show higher electrical conductivity and improved capacity retention at high C‑rates, as well as extended cycle life in both lithium‑ion cathodes and silicon anodes. The technology is designed to be cost‑effective and scalable, making it attractive for the rapidly expanding electric‑vehicle gigafactory ecosystem.
Ingevity’s Q3 2025 earnings provide context for the deal. Revenue fell 4% to $333.1 million, a decline of 11.6% year‑over‑year, largely driven by a 5% drop in the Performance Materials segment, which is sensitive to macro demand for automotive components. Despite the revenue miss, adjusted earnings per share rose to $1.52, beating the consensus estimate of $1.39 by $0.13. The beat was largely attributable to disciplined cost management and a favorable mix shift toward higher‑margin performance chemicals.
The partnership is a strategic response to the company’s recent revenue challenges. By securing local production of high‑performance CNTs, Ingevity reduces dependence on overseas suppliers, mitigates supply‑chain risk, and positions itself to capture growth in the EV battery additive market. The deal also aligns with Ingevity’s broader initiative to expand its EV battery materials portfolio, following a $60 million investment in silicon‑anode developer Nexeon in 2022.
David Li, President and CEO of Ingevity, said the agreement “validates both the strength of CHASM’s technology and Ingevity’s core competencies. It accelerates our EV battery materials strategy and strengthens our supply chain across North America and Europe.” David Arthur, CEO of CHASM, added that the deal “enables battery cell producers to achieve performance and sustainability goals without relying on overseas supply.”
Investors had previously expressed concern after the Q3 earnings report, where revenue fell and the company missed analyst expectations. The new licensing agreement is viewed as a positive step toward revenue diversification and long‑term growth, providing a counterbalance to the earlier revenue shortfall.
