3M has agreed to pay up to $7.35 billion over nine years to settle personal-injury claims from people who say they were sickened by PFAS "forever chemicals" in firefighting foam and other products, the company announced on Tuesday, November 3, 2026. The 3M PFAS settlement would resolve about 99 percent of the personal-injury lawsuits now pending against the company, covering an estimated 115,000 to 120,000 plaintiffs. It is the largest personal-injury settlement in PFAS litigation history.

Key Points

• 3M will pay up to $7.35 billion over nine years to settle PFAS personal-injury claims (present value $5.8 billion).
• The deal covers about 99 percent of current claims, with 115,000 to 120,000 plaintiffs eligible.
• Payments start with $50 million in 2026, nothing is due in 2027, and over $1 billion is payable each year from 2028 to 2033.
• 3M did not admit liability and can withdraw if too few plaintiffs join the settlement.
• The deal is separate from 3M's 2023 settlement of $10.3 billion with US public water systems.

What Happened

The settlement was announced on Tuesday, November 3, 2026. It covers people who say they developed illnesses after exposure to groundwater contaminated by PFAS, the synthetic chemicals in aqueous film-forming foam, the firefighting foam sprayed at military bases, airports and industrial sites. The claims sit inside and outside the federal multidistrict litigation over the foam in South Carolina.

The payment schedule is heavily backloaded: $50 million this year, nothing in 2027, and more than $1 billion in each year from 2028 to 2033. 3M put the present value at $5.8 billion and said it would take a $5.8 billion pretax charge in the fourth quarter of 2026. The charge will weigh on reported earnings for the quarter, though the cash leaves the company gradually over most of a decade.

Background and Context

PFAS, short for per- and polyfluoroalkyl substances, are thousands of man-made chemicals prized for resisting water, grease and heat. They are called "forever chemicals" because they barely break down in the environment or the human body. Studies have linked them to some cancers, liver damage, thyroid problems and reduced immune response, and they have been found in the blood of most Americans.

The contamination came largely from firefighting foam. For decades, military bases, airports and fire-training sites sprayed the foam in drills and emergencies, and the chemicals seeped into soil and groundwater. People living nearby, including service members, firefighters and their families, say they drank and bathed in contaminated water for years before the danger was widely understood.

3M was one of the main makers of the foam and the PFAS chemicals inside it. It has faced thousands of lawsuits from individuals, plus separate claims from states, cities and water utilities. In 2023 it agreed to pay up to $10.3 billion over 13 years to settle claims from US public water systems, covering the cost of filtering PFAS out of drinking water but not the personal-injury claims now being settled.

3M PFAS Settlement: What the $7.35 Billion Deal Covers

The new deal is aimed squarely at the people, not the water systems. It covers personal-injury claims from plaintiffs who say PFAS exposure made them ill, and is designed to bring near-total closure to that part of the litigation, covering about 99 percent of the claims now filed. An estimated 115,000 to 120,000 plaintiffs are eligible, and the settlement sets out how the money will be divided among them.

The structure gives 3M an exit if participation falls short: it can withdraw if too few plaintiffs agree to join, a standard walk-away clause in mass settlements. It also admitted no liability, saying it was prepared to keep defending itself in court. For plaintiffs, the trade-off is certainty: a defined payout over nine years instead of years of individual trials with uncertain outcomes.

Reactions and Quotes

3M chairman William Brown called the settlement a "significant milestone" that removes a long-running source of uncertainty over 3M's future. The company says the deal lets it move past a legal overhang that has weighed on its shares for years, even as it insists it did nothing wrong.

For the plaintiffs, the settlement brings the prospect of compensation after years of litigation, though the money will arrive slowly and must be divided among a very large group. Lawyers have not yet said how much individual plaintiffs can expect, and the final value depends on how many people join. The deal still needs court approval, and the details of who qualifies will be worked out in the months ahead.

Why It Matters

The settlement matters because it is the largest resolution yet of the human cost of PFAS contamination. The 2023 water-system deal addressed the cost of cleaning drinking water. This deal addresses the people who say the chemicals made them sick, and its size reflects how many Americans were exposed and for how long.

It also matters for what it signals to other companies. PFAS litigation is still spreading, with cases against other chemical makers, foam manufacturers and users working through the courts. A settlement of this scale sets a benchmark for resolving the personal-injury side of the crisis, and may push other defendants toward their own deals rather than years of trials.

What Happens Next

The next step is court approval. The settlement must be approved by the court overseeing the federal multidistrict litigation in South Carolina, and plaintiffs will be given the chance to join or opt out. If enough join, payments begin on schedule, with the first $50 million due this year and the large annual payments starting in 2028.

Investors will be watching how the $5.8 billion charge affects 3M's fourth-quarter results and whether the settlement truly closes the book on its PFAS liability. State and local claims, and lawsuits from people who do not join, remain outside it. The wider PFAS cleanup, from filtering drinking water to remediating contaminated land, will continue for years.
