As previously reported, governments in the United States and internationally have increasingly been regulating a broad group of perfluoroalkyl and polyfluoroalkyl substances, collectively known as "PFAS," including some produced by the Company prior to the end of 2025.
The PFAS group of substances contains several categories and classes of durable chemicals and materials with properties that include oil, water, temperature, chemical, and fire resistance, as well as electrical insulating properties. The strength of the carbon-fluorine bond also means that these compounds do not easily degrade. These characteristics have made PFAS substances critical to the manufacture of a wide range of products, including electronic devices such as cell phones, tablets, and semi-conductors. They are also used to help prevent contamination of medical products like surgical gowns and drapes. Commercial aircraft and low-emissions vehicles also rely on PFAS technology. 3M is just one of a number of companies that manufactured PFAS compounds prior to the end of 2025.
As science and technology evolve and advance, and in response to evolving knowledge and the understanding that certain PFAS compounds had the potential to build up over time, 3M announced in 2000 that it would voluntarily phase out production of two PFAS substances, perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) globally as a precautionary measure. Most of the phase out activities in the United States were completed by the end of 2002. The phase out included materials used to produce certain repellents and surfactant products, and products including Aqueous Film Forming Foam (AFFF) and certain coatings for food packaging, for example. Following the phase out of PFOA and PFOS production, the Company has continued to review, control, or eliminate the presence of certain PFAS in purchased materials, as intended substances in products, or as byproducts of some of 3M's current manufacturing processes, products, and waste streams.
3M announced in December 2022 it would take two further actions with respect to PFAS (2022 PFAS Announcement): exiting all PFAS manufacturing by the end of 2025, and working to discontinue the use of PFAS across its product portfolio by the end of 2025. 3M completed its exit of PFAS manufacturing at the end of 2025. 3M will continue to take actions to address PFAS manufactured prior to the exit. For example, the Company's water treatment assets at facilities that manufactured PFAS will continue to treat PFAS from historical manufacturing activities and remediate residual PFAS in waste streams from the Company's operations. 3M also will continue to work through the disposition of its assets and its interests in manufacturing facilities, which may include dismantling, cleaning and repurposing, and other dispositions of facilities or equipment. 3M remains in ongoing discussions with customers, government authorities, and other stakeholders and interested parties about customer agreements and the Company's interests in assets and facilities, which may be owned or leased from other parties that have interests and rights related to those facilities. The Company recognized a $0.8 billion pre-tax charge in the fourth quarter of 2022 associated with the 2022 PFAS Announcement related to asset impairments, and will incur additional expenses in connection with the 2022 PFAS Announcement. In addition, the 2022 PFAS Announcement involves risks, including: the actual costs and financial impact of such exit; potential governmental or regulatory actions relating to PFAS or the Company's exit; the Company's ability to identify and manufacture, or procure from third parties if possible, acceptable substitutes for PFAS-containing materials in 3M's supply chain; the possibility that such non-PFAS options are not available or that such substitutes may not achieve the anticipated or desired commercial, financial or operational results; potential litigation relating to the Company's exit or to any products that include third-party manufactured materials containing PFAS that are incorporated into the products the Company sells; and the possibility that the exit will involve greater costs than anticipated, or may otherwise have negative impacts on the Company's relationships with its customers and other parties.
As also noted, 3M has been working to discontinue the use of PFAS across its product portfolio and has made substantial progress in eliminating such use in the Company's products. With respect to PFAS-containing products not manufactured by 3M in the Company's supply chains, the Company continues to evaluate the availability and feasibility of adopting and incorporating third-party products into its product portfolio that do not contain PFAS. Depending on the availability and feasibility of such third-party products not containing PFAS, the Company continues to evaluate circumstances in which the use of PFAS-containing products manufactured by third parties and used in certain applications in 3M's product portfolios will continue beyond the end of 2025. Examples of PFAS-containing third-party products include lithium ion batteries, printed circuit boards, certain seals and gaskets, and other products widely used in commerce across a variety of industries, and in some cases required by regulatory or industry standards. In certain cases, sales and use of products manufactured before the end of 2025, and sales of products through customer transitions to new products, regulatory approvals, or customer re-certifications or re-qualifications of substitutes or replacements to eliminate the use of PFAS, were not completed by the end of 2025 and transitional efforts are ongoing.
3M has noticed several global regulatory trends related to PFAS, including decreasing emission standards and limits set for the presence of certain PFAS in various media, and the inclusion in regulatory activity of a broadening group of PFAS. Developments in these and other global regulatory trends may require additional actions by 3M, including investigation, remediation and compliance actions, and may result in additional litigation and enforcement action-related costs.
Under certain environmental laws, including the United States Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA") and similar state laws, the Company may be jointly and severally liable, sometimes with other potentially responsible parties, for the costs of investigation and remediation of environmental contamination at current or former facilities and at off-site locations where substances designated as "hazardous substances" have been released or disposed of. The Company has identified numerous locations, many of which are in the United States, at which it may have some liability for remediation of contamination under applicable environmental laws. As a result of the CERCLA designation of PFOA and PFOS as hazardous substances in 2024, and to the extent EPA finalizes additional proposals related to PFAS, 3M may be required to undertake additional investigative or remediation activities, including where 3M conducts operations or where 3M has disposed of waste. 3M may also face additional litigation from other entities that have liability under these laws for claims seeking contribution for clean-up costs other entities might have.
The Company has been voluntarily cooperating with various local, state, federal (primarily the U.S. Environmental Protection Agency (EPA)), and international agencies in their reviews of the environmental and health effects of certain PFAS produced by the Company prior to the end of 2025. 3M currently is defending lawsuits concerning various PFAS-related products and chemistries, and is subject to unasserted and asserted claims and governmental regulatory proceedings and inquiries related to the production and use of PFAS in a variety of jurisdictions, as discussed in Note 17, "Commitments and Contingencies," within the Notes to Consolidated Financial Statements. 3M has seen increased public and private lawsuits being filed on behalf of states, counties, cities, and utilities alleging, among other things, harm to the general public and damages to natural resources, some of which are pending in the AFFF multi-district litigation and some of which are pending in other jurisdictions, including internationally. Various factors or developments in these and other disclosed actions could result in future charges that could have a material adverse effect on 3M. For example, as described in greater detail in Note 17, "Commitments and Contingencies," within the Notes to Consolidated Financial Statements, in June 2023, the Company entered into a class-action settlement ("PWS Settlement") to resolve a wide range of drinking water claims by public water suppliers in the United States regarding PFAS. The court approved that settlement in March 2024. 3M will pay $10.5 billion to $12.5 billion in total to resolve the claims released by the PWS Settlement, with payments to be made from 2024 through 2036, in exchange for a release of certain claims, as described further in Note 17. Unexpected events related to the PWS Settlement, including the potential impact of the PWS Settlement on other PFAS-related matters, could have a material adverse effect on the Company's results of operations, cash flows or consolidated financial position. In addition, as previously disclosed, in connection with the separation of Solventum, the Company agreed to retain liabilities related to PFAS for certain products sold by the Company's health care businesses prior to the separation and by Solventum for a limited period of time following the separation.
Governmental inquiries, lawsuits, or laws and regulations involving PFAS could lead to the Company incurring liability for damages or other costs, civil or criminal proceedings, the imposition of fines and penalties, or other remedies, including orders to conduct remediation, as well as restrictions on or added costs for business operations going forward, including in the form of restrictions on discharges at manufacturing facilities, requiring the installation of control technologies, suspension or shutdown of facility operations, switching costs in seeking alternative sources of supply, potential customer damage claims due to supply disruptions or otherwise, restoration of and/or compensation for damages to natural resources, personal injury and property damages, and reporting requirements or bans on PFAS and PFAS-containing products manufactured by the Company. The Company may also record charges relating to ongoing asset use, retirement or disposition, some of which may be material, depending in part on how the Company manages related assets in connection with these activities. Any of the foregoing could have a material adverse effect on the Company's results of operations, cash flows or consolidated financial position.
