3M agrees to $7.35 billion settlement covering 115,000 PFAS firefighting foam injury claims

3M has agreed to pay $7.35 billion over nine years to settle the vast majority of personal injury claims against it over PFAS 'forever chemicals' in firefighting foam — a deal covering an estimated 115,000 to 120,000 plaintiffs and representing the company's largest legal reckoning yet with the human health consequences of those compounds.

The agreement, announced November 3, 2026, resolves about 99% of current claims both inside and outside the federal Aqueous Film-Forming Foam (AFFF) multidistrict litigation (MDL) in federal district court in South Carolina. The $7.35 billion nominal figure carries a present value of $5.8 billion — the amount 3M will book as a pre-tax charge in the fourth quarter of 2026, classified as a special item that leaves the company's full-year guidance unchanged.

This settlement is a significant milestone for 3M and substantially reduces litigation uncertainty.

The lawsuits center on AFFF — a firefighting foam widely used at military bases and airports — which contained PFAS compounds including PFOS and PFOA. These chemicals persist in the environment and accumulate in the human body; plaintiffs alleged they caused illnesses and certain cancers. The most common claims accused 3M of knowing about the risks and failing to warn users, according to Yahoo Finance.

Payments are structured to ease 3M's near-term cash burden: the company will pay $50 million before the end of 2026 and nothing in 2027, with roughly 20% of the total due in the final two years of the nine-year schedule, according to 3M's announcement. The deal also includes a $680 million reserve fund — part of the overall $7.35 billion commitment — to handle remaining and future personal injury claims not captured by the primary settlement.

3M is not admitting liability under the agreement and retains the right to terminate the settlement and return to litigation if plaintiff participation falls below a threshold the company did not publicly specify. An anticipated court order from the MDL judge is also expected to establish evidentiary and timing requirements for any plaintiffs who choose to litigate rather than join the resolution.

For the thousands of victims who have sought answers and accountability for nearly a decade, 3M's $7.35 billion settlement is welcome news.— Fred Thompson and David Hoyle, Motley Rice Attorneys and MDL plaintiff counsel

This settlement follows 3M's earlier resolution with U.S. public water systems over PFAS contamination, as well as a separate settlement with the State of New Jersey. Together, the deals mark 3M's effort to draw a line under decades of PFAS liability. The company began voluntarily phasing out PFOS and PFOA compounds in 2000 under government pressure, and in 2022 announced it would stop manufacturing all PFAS globally by the end of 2025 — a goal it says it met.

For 3M, the payment structure — spread across nine years with back-loading toward the end — is designed to align with what the company describes as its other financial obligations while preserving capacity for investment. 3M said its free cash flow and capital markets access give it flexibility to meet the settlement payments alongside other priorities.

What remains open is the roughly 1% of claims not covered by the deal, as well as any future plaintiffs who may emerge. The $680 million reserve and the anticipated court order governing future litigants are the mechanisms 3M and plaintiff counsel have built to manage that tail risk.

Why it matters — The settlement is the largest resolution yet of personal injury claims tied to PFAS 'forever chemicals' and, combined with 3M's earlier water-system deal, signals a potential endpoint to one of the most expansive environmental health litigations in U.S. corporate history — while leaving open questions about future claimants and long-term PFAS health consequences.
