GrafTech Hit with Derivative Suit over Environmental Disclosures

June 10, 2025
Carponi v. Rintoul, No. 1:25-cv-01216 (N.D. Ohio)

Shareholders have filed derivative claims on behalf of GrafTech International over the graphite electrode product manufacturer’s alleged failure to disclose environmental contamination in Mexico. The complaint alleges that GrafTech executives made false and misleading statements about its pursuit of “an environmentally conscious agenda,” while it was in fact ignoring environmental laws and regulations at its factory in Monterrey.

The derivative plaintiff contends that GrafTech contaminated the Monterrey community for decades with gases and particulate matter that cause cancer but did not disclose those practices to investors. When the environmental contamination was revealed in 2022, the company’s stock price dropped. The derivative case was filed after a shareholder class action based on similar allegations.
