3M signed a private settlement of alleged PFAS personal injury claims that it says about 115,000 to 120,000 plaintiffs are eligible to join. The headline amount depends on participation, and the payment schedule calls for $50 million in 2026 and nothing in 2027.
3M, the Post-it maker, agreed in 2023 to pay public water suppliers up to $12.5 billion over 13 years for PFAS contamination claims. In its November 3 securities filing, 3M said it signed a private settlement for PFAS personal injury claims with a total nominal amount of $7.35 billion. People asserting a listed injury and PFAS exposure may qualify to enroll; those who do must give 3M a full release. The commitment runs through 2034 and depends on participation by a group 3M estimates at roughly 115,000 to 120,000 eligible plaintiffs: $50 million is scheduled in 2026, nothing in 2027, and 3M can walk away if enrollment falls short. For a legal department weighing its own mass tort exit, the structure is worth studying: the big installments begin only after the enrollment count is in and both sides’ rights to walk away have expired or been waived.
The claims concern alleged injuries from exposure to PFAS, chemicals used in firefighting foam and other products. They are the focus of a multidistrict litigation, or MDL (thousands of cases gathered before one judge), of more than 15,000 cases in federal court in South Carolina, though 3M says the agreement also addresses current claims outside that proceeding. Its filing states that 3M admits no liability or wrongdoing. The signed Master Settlement Agreement lists kidney, testicular, liver and thyroid cancer, ulcerative colitis, and thyroid disease as eligible injuries.

The payment schedule starts with $50 million due within 30 days of the November 3 signing. The agreement directs that payment into a settlement fund and permits necessary administrative costs to come from it. If either side terminates the agreement, whatever remains of that initial payment, with accrued interest, returns to 3M. For calculating claimant awards, the agreement counts it as part of the main settlement payment.
The larger payments begin much later. Six installments of $1.045 billion are scheduled from 2028 through 2033. The first is due within 30 days after both sides’ termination rights expire or are waived, but no earlier than January 15, 2028. The schedule also sets aside potential payments tied to participation and a reserve fund of up to $680 million, all within the overall commitment. According to 3M’s announcement, about 20% of payments fall in the final two years.
The P&L translation: 3M plans to record a roughly $5.8 billion pretax charge in the fourth quarter, the present value it assigns to its contributions under the agreement. The gap between that charge and the $7.35 billion nominal figure reflects discounting for payments that stretch to 2034.

The agreement requires participating claimants to give 3M a full release of their PFAS personal injury claims and certain related claims. A claims administrator will calculate both an overall participation rate and a separate rate for a defined subset of eligible claimants. Those calculations determine whether 3M can terminate and whether additional payments become due. The agreement puts the termination conditions in a confidential exhibit.
Once the administrator reports the participation numbers, 3M generally has 45 days to exercise its termination right, subject to the agreement’s challenge and extension provisions. The negotiating plaintiffs’ counsel has a termination right as well. If 3M terminates and further mediation fails, the agreement says the settlement ends and the claims administrator destroys submitted releases. Each claimant’s choice to sign or stay out feeds the count that decides both the money and whether 3M can walk away.
The agreement reaches beyond people who already have a case on file. It calls for counsel to identify eligible people they represent even if those people have not sued or do not intend to join. It also calls for participating counsel to stop advertising for PFAS personal injury claims as of the signing date. The identification requirements aim to create an initial list of eligible claimants. The agreement calculates participation later using the number of eligible claimants at that time, subject to specified exclusions.
The parties say in the agreement that they expect a South Carolina federal court identification order. As written, that anticipated order would require lawyers to identify their eligible clients within 10 days of the November 3 settlement date, pointing to November 13. For eligible people without counsel, the agreement measures the 10 days from issuance of the order instead. The November 13 date assumes the court enters the order as the parties proposed.
That is the next visible step in a deal that 3M says could address approximately 99% of current personal injury claims inside and outside the consolidated litigation. William Brown, 3M’s chairman and CEO, called the agreement a significant milestone that reduces litigation uncertainty. The first $1.045 billion installment is payable within 30 days after both parties waive their termination rights or those rights expire, but no earlier than January 15, 2028.
