New Hampshire Joins Lawsuit to Protect PFAS Claims Against Dupont, Corteva Assets

Concord, NH - Attorney General John M. Formella announces that New Hampshire has joined a bipartisan coalition of 16 states and sovereign governments in a lawsuit against Indiana-based EIDP, the chemical company historically known as DuPont, its parent company Corteva, and a newly created company called Vylor. The lawsuit seeks to unwind the defendants' transfer of DuPont and Corteva's Pioneer seeds business to Vylor, which the states allege was structured to move substantial assets away from companies facing significant liabilities, including liabilities associated with PFAS contamination.

"Companies cannot simply move valuable assets out of reach and leave states, communities and taxpayers to deal with the liabilities left behind," said Attorney General Formella. "New Hampshire has a responsibility to protect its citizens and to ensure that companies are held accountable for the consequences of their conduct. We are joining our fellow states to preserve our ability to pursue these claims and to ensure that the assets necessary to resolve them remain available."

The lawsuit, filed in Marion County, Indiana, asks the court to temporarily freeze the transferred assets and prevent DuPont and Corteva from using remaining funds for dividends and stock buybacks while preventing Vylor from selling or pledging the assets it received in the transaction.

According to the states' complaint, on October 1, 2026, DuPont and Corteva transferred the Pioneer seeds business, a major corn and soybean operation, to Vylor. The states allege that Vylor received approximately three-quarters of the value previously held by DuPont and Corteva that could have been available to satisfy claims by the states and other creditors, while the companies' substantial PFAS-related liabilities remained with DuPont.

The states allege that the transaction was designed to interfere with creditors' ability to recover on those liabilities and to leave DuPont with significantly fewer assets available to address claims arising from its historic manufacture, use and release of PFAS, commonly known as "forever chemicals."

The multistate lawsuit is part of broader efforts by states to hold DuPont and related companies accountable for PFAS contamination of our natural resources and the costs associated with addressing it. The states have alleged that DuPont knew or should have known for decades about the risks associated with PFAS and failed to adequately disclose those risks to regulators, consumers and the public.

PFAS are a class of chemicals that have been widely used because of their resistance to heat, water and grease. Many PFAS persist in the environment and can contaminate drinking water, groundwater and soil, causing serious health impacts to the public and creating significant costs to investigate, contain and remediate contamination.

The lawsuit is pending, and the allegations contained in the complaint have not been adjudicated.

In addition to New Hampshire, the coalition includes Indiana, Alaska, Florida, Maine, Maryland, Massachusetts, New Mexico, Oregon, Pennsylvania, Rhode Island, Tennessee, Texas, Vermont and Washington, as well as the Government of Guam.
