Litigation related to Corteva’s current businesses

Inari Disputes

On September 27, 2023, Corteva filed a lawsuit in Delaware federal court against Inari Agriculture, Inc. and Inari Agriculture. N.V. (collectively “Inari”) asserting claims of Plant Variety Protection infringement, indirect patent infringement, breach of contract, and civil conversion. Corteva’s lawsuit alleges Inari illegally obtained various varieties of seed technologies from a seed depository and illegally transported them abroad for the purpose of performing gene editing on the technologies and then filing a patent for such technologies. In August 2024, the court denied Inari's motion to dismiss the complaint. In September 2024, Corteva amended its complaint to include additional infringement claims with respect to soybean and corn technologies. In May 2025, the federal court dismissed Inari’s claims of sham litigation, patent misuse, and state-based deceptive trade practices claims. This May 2025 order was amended to reinstate Inari’s estoppel defense. The trial is expected to begin in the second half of 2026.

Divested Neoprene Facility, La Place, Louisiana - EPA Compliance Inspection

In 2016, the EPA conducted a focused compliance investigation at the Denka Performance Elastomer LLC (“Denka”) neoprene manufacturing facility in La Place, Louisiana. EIDP sold the neoprene business, including this manufacturing facility, to Denka in the fourth quarter of 2015. In the spring of 2017, the EPA, the DOJ, the Louisiana Department of Environmental Quality, EIDP and Denka began discussions relating to the inspection conclusions and allegations of noncompliance arising under the Clean Air Act, including leak detection and repair. In March 2025, the EPA and DOJ dismissed the action against Denka and EIDP. Following the dismissal, a private action mirroring the government’s original claims was filed, as well as adding allegations of violations of the U.S. Resource Conservation and Recovery Act and U.S. Clean Water Act. Under the Separation Agreement, DuPont is defending and indemnifying the company in this matter.

EPA CERCLA Claim

In April 2024, the EPA also designated PFOA and PFAS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"). In November 2024, the EPA issued a letter to DuPont, EIDP and Corteva asserting CERCLA claims related to alleged PFAS contamination from six historical and present DuPont and Chemours sites and providing a demand for cleanup and restoration costs. In September 2025, the EPA announced its intent to retain the designation of PFOA and PFOS as CERCLA hazardous substances. Discussions among the parties are ongoing.
