3M COMPANY

ANNUAL REPORT ON FORM 10-K

For the Year Ended December 31, 2025

PART I

Item 1. Business

3M Company was incorporated in 1929 under the laws of the State of Delaware to continue operations begun in 1902. The Company’s ticker symbol is MMM. As used herein, the term “3M” or “Company” includes 3M Company and its subsidiaries unless the context indicates otherwise. In this document, for any references to Note 1 through Note 20, refer to the Notes to Consolidated Financial Statements in Item 8.

Available Information: The Securities and Exchange Commission (SEC) maintains a website that contains reports, proxy and information statements, and other information regarding issuers, including the Company, that file electronically with the SEC. The public can obtain any documents that the Company files with the SEC at https://www.sec.gov. The Company files annual reports, quarterly reports, proxy statements and other documents with the SEC under the Securities Exchange Act of 1934 (Exchange Act).

3M also makes available free of charge through its website (https://investors.3M.com) the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K, and, if applicable, amendments to those reports filed or furnished pursuant to the Exchange Act as soon as reasonably practicable after the Company electronically files such material with, or furnishes it to, the SEC.

General: 3M is a diversified technology company with a global presence in the following businesses: Safety and Industrial; Transportation and Electronics; and Consumer. 3M is among the leading manufacturers of products for many of the markets it serves. Most 3M products involve expertise in product development, manufacturing and marketing, and are subject to competition from products manufactured and sold by other technologically oriented companies.

Table of Contents

Business Segments: 3M manages its continuing operations in three business segments. The reportable segments are Safety and Industrial, Transportation and Electronics, and Consumer. 3M’s business segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. Refer to segment descriptions summarized below (Financial information and other disclosures relating to 3M’s business segments and operations in major geographic areas are provided in the Notes to Consolidated Financial Statements):

Business Segment Safety and Industrial Transportation and Electronics Consumer

Distribution: 3M products are sold through numerous distribution channels, including directly to users and through a wide range of e-commerce and traditional wholesalers, retailers, jobbers, distributors, and dealers in a wide variety of trades in many countries around the world. Management believes that the confidence of these partners in 3M and its products — a confidence developed through long association with skilled marketing and sales representatives — has contributed significantly to 3M’s position in the marketplace and to its growth. As part of 3M's ongoing commercial excellence initiative, the Company is focused on further strengthening and optimizing this go‐to‐market channel, enhancing partner engagement, and improving overall channel performance to support continued growth.

Table of Contents

Resources

Human Capital: On December 31, 2025, the Company employed approximately 60,500 people (full-time equivalents), with approximately 22,500 employed in the United States and 38,000 employed internationally. The ability to recruit, retain, develop, protect, and fairly compensate its global workforce are enablers of 3M’s success. This includes five general categories of focus: Health and Safety; Performance Culture; Development; People and Community; and Compensation and Benefits.

Health and Safety:

3M is committed to the safety, health, and well-being of its employees. The Company continuously evaluates opportunities to raise safety and health standards, training site leaders and conducting site visits to identify and manage environmental health and safety risks; evaluating compliance with regulatory requirements and 3M policy; and maintaining a global security operation for the protection of facilities and people on 3M sites. 3M also promotes a culture of health and well-being through disease prevention programs, on-site clinical services, employee assistance programs, and comprehensive health care benefits.

Performance Culture:

3M’s performance culture is grounded in five behavioral expectations that apply consistently across all levels of the organization: Deliver Results, Challenge the Status Quo, Instill Rigor and Accountability, Energize the Team to Act, and Act Responsibly and Respectfully. These behaviors guide how the Company evaluates, rewards, recognizes and develops its people to support a high-performance environment. Through clear communications to candidates and employees, these expectations serve as a foundation for how work gets done at 3M. Development programs for executive leaders, people leaders, and individual contributors are aligned to help ensure employees have the capabilities needed to demonstrate them effectively. 3M’s performance enablement process emphasizes clear goal setting, regular coaching, and feedback, and differentiated performance rewards to reinforce the Company’s “pay for performance” approach.

Development:

Developing employees contributes to growing 3M’s business. 3M maintains talent and succession planning processes, including regular reviews by the Company’s chief executive officer (CEO) and reporting up through the Board of Directors. The Company provides leadership development experiences through enterprise leadership development programs, job-based or project-based assignments, assessment and coaching, and targeted skill-development where leaders are given the opportunity to learn, apply, and share their skills. 3M also provides opportunities for all employees to learn, in addition to regular coaching and support from their supervisor. With the Company’s global online employee learning platform, employees are able to access unique, just-in-time development resources in over 15 languages to support their career aspirations and advance their skills.

People and Community:

3M is committed to developing a skilled, engaged, and innovative workforce and to strengthening the communities in which it operates. The Company supports its people through talent practices that attract, develop, and retain employees with a wide variety of expertise and experiences, and fosters a work environment that promotes collaboration, respect, and high performance. 3M also advances STEM and skilled‐trade readiness through volunteerism, charitable giving, and strategic community partnerships.

Compensation and Benefits:

3M invests in a professional and flexible work environment that promotes innovation, well-being, and rewards performance. 3M’s total compensation for employees includes a variety of components that support sustainable employment and the ability to build a strong financial future, including competitive market-based pay and comprehensive benefits. In addition to earning a base salary, eligible employees are compensated for their contributions to the Company’s goals with both short-term incentives and long-term incentives. Through its global pay philosophy, principles and consistent implementation, 3M is committed to providing fair and equitable pay for employees. Eligible full-time employees in the United States also have access to medical, dental, and vision plans; savings and retirement plans; a 3M employee stock purchase plan; and other resources. Some of these benefits can also be available to regular part-time employees who work at least 20 hours a week. Programs and benefits differ internationally for a variety of reasons, such as local legal requirements, market practices, and negotiations with works councils, trade unions, and other employee representative bodies.

Raw Materials: In 2025, persistent pricing pressure, tariffs and geopolitical uncertainty prompted producers to adjust capacity and restructure operations. Overall, these market conditions caused supply constraints and inflation, but were offset via negotiated supply contracts and leveraging scale across the supply base.

Table of Contents

Patents, Trademarks and Licenses:The Company’s products are sold around the world under various trademarks. The Company also owns, or holds licenses to use, numerous U.S. and foreign patents. The Company’s research and development activities generate a steady stream of inventions that are covered by new patents or trade secrets. Patents applicable to specific products extend for varying periods according to the date of patent application filing or patent grant and the legal term of patents in the various countries where patent protection is obtained. The actual protection afforded by a patent, which can vary from country to country, depends upon the type of patent, the scope of its coverage and the availability of legal remedies in the country.

The Company believes that its trademarks, patents, and trade secrets provide an important competitive advantage in many of its businesses, particularly in connection with new product introductions in markets around the world. In general, no single patent or group of related patents is in itself essential to the Company as a whole or to any of the Company’s business segments.

Government Regulation and Environmental Law Compliance: The Company’s business operations are subject to various governmental regulations in the U.S. and internationally, including, among others, those related to product liability; securities and corporate governance; antitrust and competition; intellectual property; environmental, health, and safety; tax; the U.S. Foreign Corrupt Practices Act (FCPA) and other anti-bribery and anti-corruption laws; international import and export requirements and trade sanctions compliance; laws and regulations that apply to industries served by the Company, including the False Claims Act, anti-kickback laws, and the Sunshine Act; and other matters.

3M’s manufacturing operations are affected by national, state and local environmental laws and regulations around the world. The Company places consistent emphasis on environmental responsibility. 3M has made and will continue to make, necessary expenditures, including capital expenditures, for compliance with these applicable laws and regulations. 3M is also involved in remediation actions relating to environmental matters from past operations at certain sites (refer to “Environmental Matters and Litigation” in Note 17, Commitments and Contingencies).

Environmental expenditures relating to existing conditions caused by past operations that do not contribute to current or future revenues are expensed. Reserves for liabilities for anticipated remediation costs are recorded on an undiscounted basis when they are probable and reasonably estimable, generally no later than the completion of feasibility studies, the Company’s commitment to a plan of action, or approval by regulatory agencies. Environmental expenditures for capital projects that contribute to current or future operations generally are capitalized and depreciated over their estimated useful lives. 3M cannot predict with certainty whether future costs of compliance with government regulations (including environmental regulations) will have a material effect on its capital expenditures, earnings or competitive position.

Table of Contents

Information about our Executive Officers: Following is a list of the executive officers of 3M, and their age, present position, the year elected to their present position and other positions they have held during the past five years. No family relationships exist among any of the executive officers named, nor is there any undisclosed arrangement or understanding pursuant to which any person was selected as an officer. This information is presented in the table below as of the date of the 10-K filing (February 3, 2026).

Item 1A. Risk Factors

Provided below is a cautionary discussion of what we believe to be the most important risk factors applicable to the Company. Discussion of these factors is incorporated by reference into and considered an integral part of Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Risks Related to the Global Economy and External Conditions

* The Company’s results are impacted by the effects of, and changes in, worldwide economic, political, regulatory, international trade, geopolitical, tariffs and retaliatory counter measures, and other external conditions.

During 2025, the Company derived approximately 56 percent of its revenues from outside the United States. Accordingly, the Company’s operations and the execution of its business strategies and plans are subject to global competition and economic and geopolitical risks that are beyond its control, such as, among other things, disruptions in financial markets, economic downturns, military conflicts, terrorism, public health emergencies, political changes and trends such as protectionism, economic nationalism resulting in government actions impacting international trade agreements or imposing trade restrictions such as tariffs and retaliatory counter measures, and government deficit reduction and other austerity measures in locations or industries in which the Company operates. Further escalation of specific trade tensions, including those between the U.S. and China, or more broadly in global trade conflict, could have a material adverse effect on the Company's business and operations around the world. The Company's business is also impacted by social, political, and labor conditions in locations in which the Company or its suppliers or customers operate; adverse changes in the availability and cost of capital; monetary policy; interest rates; inflation; recession; commodity prices; currency volatility or exchange control; ability to expatriate earnings; and other laws and regulations in the jurisdictions in which the Company or its suppliers or customers operate. For example, changes in local economic condition or outlooks, such as lower economic growth rates in China, Europe, or other key markets, impact the demand or profitability of the Company's products.

The global economy has been impacted by geopolitical tensions. The U.S. and other governments have imposed, and propose to impose additional, export controls and tariffs on certain products, and financial and economic sanctions on certain industry sectors and parties. These geopolitical tensions could result in, among other things, cyberattacks, supply chain disruptions (including limitations on access to rare earth minerals and other raw materials), higher energy and other commodity costs, lower consumer demand, and changes to foreign exchange rates and financial markets, and tariffs and trade restrictions may result in increased production costs and product pricing, further supply chain disruptions, limited access to end markets, lower profitability, and uncertainty related to planning long-term investments and strategies, and may have other competitive effects. Compliance with rapidly changing tariffs and trade restrictions may require significant time and resources, and in turn increase our cost of doing business, and could result in fines and penalties or reputational harm if we are found to not be in compliance. Any of the foregoing could have a material adverse effect on the Company’s business, financial condition, and results of operations.

Climate change and severe weather events, including related environmental and social regulations, as well as natural disasters, may negatively impact the Company or its customers and suppliers, in terms of availability and cost of natural resources, sources and supply of energy, product demand and manufacturing, compliance costs, and the health and well-being of individuals and communities in which we or our suppliers or customers operate.

* Foreign currency exchange rates and fluctuations in those rates may affect the Company’s ability to realize projected growth rates in its sales and earnings.

The Company’s financial statements are denominated in U.S. dollars and, as noted above, the Company derives a significant percentage of its revenues from outside the United States. As a result, the Company’s results of operations and its ability to realize projected growth rates in sales and earnings could be materially adversely impacted if the U.S. dollar strengthens significantly against foreign currencies, and the Company's results of operations may experience volatility related to changes in exchange rates. For a discussion of the impact of foreign currency exchange rates on the Company, see Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations."

Risks Related to Legal and Regulatory Proceedings

* The Company faces liabilities related to certain fluorochemicals, which could have a material adverse effect on our results.

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.

Table of Contents

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.

Table of Contents

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.

* The Company is subject to risks related to international, federal, state, and local treaties, laws, and regulations, as well as compliance risks related to legal or regulatory requirements, contract requirements, policies and practices, or other matters that require or encourage the Company or its customers, suppliers, vendors, or channel partners to conduct business in a certain way. The outcome of legal and regulatory proceedings related to compliance with these treaties, laws, regulations, and requirements could have a material adverse effect on the Company's reputation, ability to execute its strategy and its results of operations.

The Company operates globally, including in some jurisdictions that pose potentially elevated risks of fraud or corruption or increased risk of internal control issues, and is subject to risks related to international, federal, state, and local treaties, laws, and regulations, including those involving product liability; securities and corporate governance; antitrust and competition; intellectual property; environmental, health, and safety; tax; the FCPA and other anti-bribery and anti-corruption laws; international import and export requirements and trade sanctions compliance; laws and regulations that apply to industries served by the Company, including the False Claims Act, anti-kickback laws, and the Sunshine Act; and other matters. The Company is also subject to compliance risks related to legal or regulatory requirements, contract requirements, policies and practices, or other matters that require or encourage the Company and its suppliers, vendors, or channel parties, to conduct business in a certain way. Legal compliance risks also include third-party risks where the Company’s suppliers, vendors, or channel partners, or trade associations to which the Company belongs, have business practices that are inconsistent with 3M’s Supplier Responsibility Code, 3M performance requirements, or with legal requirements.

The Company is also subject to certain risks as a direct and indirect supplier to the U.S. government and other governments, such as those associated with compliance with procurement regulations, as well as the government’s rights to audit and conduct investigations and to terminate contracts. There is also uncertainty as to the extent and timing of funding that may be available for U.S. federal government and other government procurement activities. Failure by the Company or one of its customers, suppliers, vendors, or channel partners to comply with provisions of government contracts or related laws, regulations, executive orders, or other government actions could result in the Company being unable to fulfill its contract commitments under a government contract or inability to realize the full value of such contract. Significant administrative, civil or criminal liabilities, including under the U.S. False Claims Act or similar enforcement legislation, and suspension or debarment from business with the U.S. or other governments, and reputational harm, could also result from the risks noted above.

The failure to comply with the FCPA and other anti-bribery and anti-corruption laws and regulations could result in significant civil fines and penalties or criminal sanctions against the Company, which could have a material adverse effect on our business, reputation, operating results and financial condition. These laws and regulations prohibit corrupt payments by the Company's employees, suppliers, vendors, channel partners or agents. The Company is also required to maintain accurate books and records and adequate internal controls under the FCPA's accounting provisions. From time to time, the Company receives reports internally and externally, via various reporting channels deployed by its Ethics and Compliance function or otherwise (such as shareholder communications), about business and other activities that raise compliance or other legal or litigation issues. The Company has in the past been, and in the future could be, required to investigate such reports and cooperate with U.S. and foreign regulatory authorities in such investigations, audit, monitor compliance or alter its practices as part of such investigations, and the Company has in the past been, and in the future could be, required to pay fines or penalties related to its practices. While the Company maintains and implements U.S. and international compliance programs, including policies and procedures, training, and internal controls designed to reduce the risk of noncompliance, the Company's employees, suppliers, vendors, channel partners or agents may violate such policies and procedures and engage in practices that contravene relevant laws and regulations.

The Company's results of operations could experience a material adverse effect if the costs to comply with these evolving treaties, laws, regulations, and requirements are greater than projected by the Company. In addition, the outcome of legal and regulatory proceedings related to compliance with these treaties, laws, regulations, and requirements are difficult to reliably predict, may differ from the Company’s expectations, and have resulted and may in the future result in, one or more of the following: criminal or civil sanctions, including fines; limitations on the extent to which the Company can conduct business; employee and business partner terminations due to policy violations; and private rights of action that result in litigation exposure, including expenses and costs incurred in connection with settlement or court proceedings, for the Company. In addition, detecting, investigating and resolving actual or alleged violations of these acts is expensive and could consume significant time and attention of our senior management. Although the Company maintains general liability insurance to mitigate monetary exposure, the amount of the liability that may result from certain of these risks is unlikely to be fully covered by applicable insurance, and to the extent covered, will exceed the applicable limits of such insurance. Various factors or developments can lead the Company to change current estimates of liabilities and related insurance receivables, or make such estimates possible for matters previously not susceptible of reasonable estimates, such as a significant judicial ruling or judgment, a significant settlement, significant regulatory developments or changes in applicable law. A future adverse ruling, settlement, or unfavorable development could result in future charges that could have a material adverse effect on the Company’s results of operations or cash flows or its consolidated financial position. In addition, negative publicity related to the matters noted above or other matters involving the Company may negatively impact the Company’s reputation. The Company also relies on patent and other intellectual property protection, and challenges to the Company’s intellectual property rights, or claims that the Company’s activities interfere with the intellectual property rights of a third party, could cause the Company to incur significant expenses to assert or defend against such claims, could result in reduced revenue, and could damage the Company’s reputation, any of which could have a material adverse effect on the Company. For a more detailed discussion of the legal proceedings involving the Company and the associated accounting estimates, see the discussion in Note 17, “Commitments and Contingencies,” within the Notes to Consolidated Financial Statements.

Risks Related to Our Products and Customer Preferences

* The Company’s results are affected by competitive conditions and customer preferences.

Demand for the Company’s products, which impacts revenue and profit margins, is affected by, among other things: (i) the development and timing of the introduction of competitive products; (ii) the Company’s pricing strategies; (iii) changes in customer order patterns, such as changes in the levels of inventory maintained by customers, vendors, or channel partners; (iv) changes in customers’ preferences for our products, including preferences for products that do not contain third-party manufactured PFAS, the success of products offered by our competitors, and changes in customer designs for their products that can affect the demand for some of the Company’s products; and (v) changes in the business environment related to disruptive technologies, such as artificial intelligence and machine learning technologies, block-chain, expanded analytics, and other enhanced learnings from increasing volume of available data. Tariffs and other trade restrictions may also: increase the cost of raw materials and components imported from other countries, leading to higher production costs and product pricing to the extent those increased costs are offset through pricing actions; disrupt established supply chains, forcing the Company to find new suppliers or relocate production, which can be time-consuming and costly; limit the Company's access to end markets and, in turn, result in reduced sales and revenue; lower profitability; result in uncertainty related to planning long-term investments and strategies; and have other competitive effects. Any of the foregoing could have a material adverse effect on the Company’s business, financial condition, and results of operations.

* The Company’s growth objectives are largely dependent on the timing and market acceptance of its new product offerings, including its ability to continually renew its pipeline of new products and to bring those products to market.

The ability to successfully bring new products to market is subject to difficulties or delays in product development, such as the inability to identify viable new products, obtain adequate intellectual property protection, or gain market acceptance of new products. There are no guarantees that new products will prove to be commercially successful.

* The Company’s future results are subject to vulnerability with respect to materials and fluctuations in the costs and availability of purchased components, compounds, raw materials, energy, and labor due to shortages, increased demand and wages, strikes or other labor disruptions, logistics, supply chain interruptions, manufacturing site disruptions, regulatory developments, natural disasters, and other disruptive factors.

The Company depends on various components, compounds, raw materials, and energy (including oil and natural gas and their derivatives) supplied by others for the manufacturing of its products. Supplier relationships have been and could be interrupted or terminated in the future due to events such as supplier material shortages, climate impacts and severe weather events, natural and other disasters, and other disruptive events such as those noted in the first risk factor above. In addition, some of our suppliers are limited- or sole-source suppliers, and our ability to meet our obligations to customers depends on the performance, product quality, and stability of such suppliers and the Company's ability to source adequate alternatives in a cost-effective manner. Any sustained interruption in the Company’s receipt of adequate supplies, supply chain disruptions impacting the distribution of products, or disruption to key manufacturing sites’ operations due to natural and other disasters or events, such as government actions relating to discharge or emission permits, strikes or other labor disruptions, or other legal or regulatory requirements, could have a material adverse effect on the Company and its ability to fulfill supply obligations to its customers. The Company could incur contractual penalties, experience a deterioration in customer relationships, or suffer harm to its reputation if the Company is unable to fulfill its obligations to customers, any of which could have a material adverse effect on the Company. In addition, there can be no assurance that the Company's processes to minimize volatility in component and material pricing will be successful or that future price fluctuations or shortages will not have a material adverse effect on the Company.

Risks Related to Our Business

* The Company employs information including operational technology systems to support its business and to collect, store, and/or use proprietary and confidential information, including ongoing phased implementation of an enterprise resource planning (ERP) system as part of its business transformation on a worldwide basis over the next several years. Network disruptions, security and data breaches, cyberattacks, and other cybersecurity incidents involving the Company’s information technology systems, networks and infrastructure could: disrupt or interfere with the Company’s operations; result in the compromise and misappropriation of proprietary and confidential information belonging to the Company or its customers, suppliers, and employees; and expose the Company to numerous expenses, liabilities, and other negative consequences, any or all of which could have a material adverse effect on the Company’s business, reputation, and results of operations.

In the ordinary course of business, the Company relies on centralized and local information technology networks and systems, some of which are provided, hosted, or managed by vendors and other third parties, to process, transmit, and store electronic information, and to manage or support a variety of businesses. Additionally, the Company collects and stores certain data, including proprietary business information, and has access to confidential or personal information in certain of our businesses that is subject to artificial intelligence, privacy and cybersecurity laws, regulations, and customer-imposed controls. Third parties and threat actors, including organized criminals, nation-state entities, and/or nation-state supported actors, regularly attempt to gain unauthorized access to the Company’s information and operational technology networks and infrastructure, data, and other information, and many such attempts are becoming increasingly sophisticated.Despite our cybersecurity and business continuity counter measures (including employee and third-party training, monitoring of networks and systems, patching, maintenance, and backup of systems and data), the Company’s information and operational technology systems, networks and infrastructure have experienced and are expected to experience cyberattacks of various degrees of sophistication, and are susceptible to insider threat, compromise, damage, disruption, or shutdown, including as a result of the exploitation of known or unknown hardware or software vulnerabilities, or zero day attacks, in our systems or the systems of our vendors and third-party service providers, the introduction of computer viruses, malware or ransomware, service or cloud provider disruptions or security breaches, phishing attempts, employee error or malfeasance, power outages, telecommunication or utility failures, systems failures, natural disasters, or other catastrophic events. The Company’s increased adoption of remote working, initially driven by the COVID-19 health pandemic, also introduces additional threats and risk of disruptions to our information technology systems, networks and infrastructure. Despite the Company's cybersecurity counter measures, it is possible for security vulnerabilities or a cyberattack to remain undetected for an extended time, up to and including several months, and the prioritization of decisions with respect to security measures and remediation of known vulnerabilities that we and the vendors and other third parties upon which we rely make may prove inadequate to protect against these attacks. While we and third parties we utilize have experienced, and expect to continue to experience, cybersecurity incidents that could lead to other disruptions of the Company’s and the third parties' information and operational technology systems and infrastructure, we do not believe that any such cybersecurity incidents to date have had a material impact on the Company. Any cybersecurity incident or information or operational technology network disruption could result in numerous negative consequences, including the risk of: legal claims or proceedings, investigations or enforcement actions by U.S., state, or foreign regulators; liabilities or penalties under applicable laws and regulations, including privacy laws and regulations in the U.S. and other jurisdictions; interference with the Company’s operations; the incurrence of remediation costs; loss of intellectual property protection; the loss of customer, supplier, or employee relationships; and damage to the Company’s reputation, any of which could have a material adverse effect the Company’s business. Although the Company maintains insurance coverage for various cybersecurity and business continuity risks, there can be no guarantee that all costs, damages, expenses or losses incurred will be fully insured nor reimbursed through insurance recoveries.

*The Company’s use of artificial intelligence technologies exposes the Company to risks which could have a material adverse effect on the Company’s business, reputation and results of operations.

Artificial intelligence (AI) technologies support a range of the Company’s activities, including research and development, operational processes, customer facing tools, and other business functions. The use of AI introduces risks that could adversely affect the Company’s business, results of operations, or financial condition. AI systems may produce inaccurate, biased, or incomplete outputs, which could lead to operational errors, reduced product or service quality, or unintentional impacts on business decisions. External vendors and third party AI tools may expose the Company to additional risks, including insufficient transparency into model performance, vulnerabilities in underlying technologies, or disruptions in service availability. AI development and deployment also require security, and proper governance of the data used. Use of AI tools, including third party platforms, increases the risk of unauthorized disclosure, loss, or misuse of confidential, personal, or commercially sensitive information. In addition, there is a risk that employees or contractors could inadvertently input confidential company information or third party proprietary data into AI systems, including systems not designed for secure handling of such information. These actions could result in violations of contractual obligations, data protection requirements, or intellectual property rights, and could expose the Company to legal, regulatory, or reputational harm. Emerging and evolving regulations related to AI use, transparency, safety, and accountability may require additional investment, changes to existing processes, or limitations on the development and application of these technologies. Rapid advances in AI may also create competitive pressures or require ongoing investment to maintain effectiveness, and failures to manage, govern, or deploy AI responsibly could impair the Company’s ability to achieve expected efficiencies or strategic objectives. While the Company will seek to develop and use artificial intelligence responsibly, and will attempt to identify and mitigate ethical, privacy, legal or other issues presented by its use, there can be no assurance that the Company will be fully successful in doing so, and may be subject to data breaches, allegations of unauthorized access to, or use of, third party data, information, or intellectual property rights, or other risks, which may lead to financial losses, legal liability, regulatory scrutiny and reputational damage.

* Acquisitions, strategic alliances, divestitures, and other strategic events resulting from portfolio management actions and other evolving business strategies could affect future results.

The Company monitors its business portfolio and organizational structure and has made and may continue to make acquisitions, strategic alliances, divestitures, and changes to its organizational structure. With respect to acquisitions and strategic alliances, future results will be affected by, as applicable, the Company’s ability to integrate acquired businesses quickly and obtain the anticipated synergies and the Company's ability to operationalize and derive anticipated benefits from alliances. Divestitures may include continued involvement in the divested businesses, such as through transitional or longer-term supply or distribution arrangements, following the transaction, and may result in unexpected liabilities through indemnification or other risk-shifting mechanisms in the applicable divestiture agreement. For example, in connection with the separation of Solventum, the Company and Solventum entered into various agreements that provide for the performance of certain services or provision of goods by each company for the benefit of the other and that may result in unexpected liabilities related to indemnification obligations or non-performance by Solventum. A summary of the material terms of these agreements can be found in the section entitled “Certain Relationships and Related Party Transactions—Agreements with 3M” in Solventum’s Information Statement, dated March 13, 2024, which was included as Exhibit 99.1 to Solventum’s Current Report on 8-K filed with the SEC on March 13, 2024. Any of the foregoing could have a material adverse effect on the Company’s future results.

* The Company’s future results may be affected by its operational execution, including through organizational restructurings and scenarios where the Company generates fewer productivity improvements than planned.

The Company’s financial results depend on the successful execution of its business operating plans. The Company utilizes various tools, such as continuous improvement, to improve productivity and reduce expenses and engages in ongoing global business transformation, including restructurings from time to time, to streamline its operations, improve operational efficiency, productivity, and the speed and efficiency with which it serves customers. Workforce restructuring activities are expected to deliver benefits, but also impact business groups, functions, and geographies. There can be no assurance that we will realize the benefits of such activities, or that such activities will not result in unexpected or negative consequences, such as: a reduced ability to generate sales; a relationship impact with employees; or a reduced ability to provide the experience that our customers, suppliers, vendors, and channel partners expect from us. In addition, the ability to adapt to business model and other changes, including responding to evolving customer needs and service expectations, are important, and, if not done successfully, could negatively impact the Company’s ability to win new business and enhance revenue and 3M’s brand. Operational challenges, including those related to customer service, pace of change and productivity improvements, could have a material adverse effect on the Company’s business, financial condition, and results of operations.

Risks Related to Financial and Capital Markets and Tax Matters

* The Company's defined benefit pension and postretirement plans are subject to financial market risks that could have a material adverse effect on our results.

The performance of financial markets and discount rates impact the Company's funding obligations under its defined benefit plans. Significant changes in market interest rates, decreases in the fair value of plan assets and investment losses on plan assets, and legislative or regulatory changes relating to defined benefit plan funding may increase the Company's funding obligations and could have a material adverse effect on its results of operations and cash flows.

* Change in the Company’s credit ratings or increases in benchmark interest rates could increase cost of funding.

The Company’s credit ratings are important to 3M’s cost of capital. The major rating agencies routinely evaluate the Company’s credit profile and assign debt ratings to 3M. This evaluation is based on a number of factors, which include financial strength, business and financial risk, as well as transparency with rating agencies and timeliness of financial reporting. The Company’s credit ratings have served to lower 3M’s borrowing costs and facilitate access to a variety of lenders. As of the date of this report, 3M has a credit rating of A3, stable outlook from Moody's Investors Service, a credit rating of BBB+, stable outlook from S&P Global Ratings, and a credit rating of A-, stable outlook from Fitch Ratings. The addition of further leverage to the Company’s capital structure could impact 3M’s credit ratings in the future. Failure to maintain strong investment grade ratings and further downgrades by the ratings agencies, would adversely affect the Company’s cost of funding and could have a material adverse effect on the Company's liquidity and access to capital markets. In addition, interest expenses could increase due to a rise in interest rates.

* Changes in tax rates, laws, or regulations could adversely impact our financial results.

The Company’s business is subject to tax-related external conditions, such as tax rates, tax laws and regulations, changing political environments in the U.S. and foreign jurisdictions that impact tax examination, and assessment and enforcement approaches. In addition, changes in tax laws including further regulatory developments arising from U.S. or international tax reform legislation could result in a tax expense or benefit recorded to the Company’s Consolidated Statement of Earnings. In connection with the Base Erosion and Profit Shifting (BEPS) Integrated Framework provided by Organization for Economic Cooperation and Development (OECD), determination of multi-jurisdictional taxation rights and the rate of tax applicable to certain types of income may be subject to potential change. Due to the evolving nature of global tax laws and regulations and compliance approaches, it is currently not possible to assess the ultimate impact of these actions on our financial statements, but these actions could have a material adverse effect on the Company's financial results.

Risks Related to the Company’s Aearo Entities and Combat Arms Earplug Settlement

* The Company is subject to risks related to the Company's Aearo Entities and CAE Settlement.

As previously disclosed, and as discussed further in Note 17, “Commitments and Contingencies,” within the Notes to Consolidated Financial Statements, Aearo Technologies sold Dual-Ended Combat Arms – Version 2 earplugs starting in about 1999. 3M acquired Aearo Technologies in 2008 and sold these earplugs from 2008 through 2015, when the product was discontinued. 3M and Aearo Technologies believe the Combat Arms Earplugs were effective and safe when used properly, but nevertheless faced significant litigation relating to the earplugs. In August 2023, the Company and the Aearo Entities entered into a settlement arrangement (as amended, the “CAE Settlement”) which is structured to promote participation by claimants and is intended to resolve, to the fullest extent possible, all litigation and alleged claims involving the CAE sold or manufactured by the Aearo Entities and/or 3M. Pursuant to the CAE Settlement, 3M will contribute a total amount of $6.0 billion between 2023 and 2029. Payments to claimants are subject to certain conditions, including providing 3M with a full release of any and all claims involving the CAE. As of the final registration date for the CAE Settlement, more than 99% of claimants are participating in the settlement. The CAE Settlement is subject to risk and uncertainties, including, but not limited to, whether there will be a significant number of future claims by plaintiffs that decline to participate in the CAE Settlement, whether the CAE Settlement is appealed or challenged, or the filing and outcome of additional litigation in the United States and internationally relating to the products that are the subject of the CAE Settlement. These and other events related to the CAE Settlement, including the potential impact of the CAE Settlement on related matters, could have a material adverse effect on the Company’s results of operations, cash flows or consolidated financial position.

Risks Related to the Spin-off of Solventum, the Company’s Former Health Care Business

* The Company is subject to risks related to the separation of Solventum, the Company's former Health Care business, into an independent public company.

On April 1, 2024, the Company completed the planned spin-off of its health care business, which is known as Solventum Corporation, as an independent company. There can be no assurance that the anticipated benefits of the transaction will be realized, or that the costs or dis-synergies of the transaction (including costs of related restructuring transactions) will not exceed the anticipated amounts, in each case in the amounts or within the timeframes that were anticipated. The separation may also impose challenges on the Company and its business, including potential impacts on the Company’s relationships with its customers, employees, regulators, and other counterparties.

In connection with the separation, the Company and Solventum entered into various agreements that provide for the performance of certain services or provision of goods by each company for the benefit of the other, including a separation and distribution agreement, a transition services agreement, a tax matters agreement, an employee matters agreement, a transition distribution services agreement, a transition contract manufacturing agreement, a stockholder’s and registration rights agreement, an intellectual property cross license agreement, a master supply agreement, and a reverse master supply agreement. Performance under these agreement or other related conditions outside of the Company’s control could materially affect our operations and future financial results.

Following the separation, the Company is a smaller, less diversified company than it was prior to the separation, which could make the Company more vulnerable to factors impacting its performance, such as changing market conditions and market volatility. In addition, the Company may be unable to find suitable alternatives for goods and services that Solventum temporarily provides to the Company pursuant to the agreements noted above, or such alternative goods and services may be more expensive than provided by Solventum to the Company.

The Company retained an equity interest in Solventum in connection with the spin-off. The Company cannot predict the trading price of shares of Solventum’s common stock and the market value of the Solventum shares is subject to market volatility and other factors outside of the Company’s control. The Company intends to divest its ownership interest in Solventum within five years from the spin-off, but there can be no assurance regarding the timing of, or timeframe over which, such divestiture or divestitures may occur, or the amount of proceeds received by the Company in connection with any such divestitures.

In addition, while it is intended that the transaction be tax-free to the Company’s stockholders for U.S. federal income tax purposes, there is no assurance that the transactions will qualify for this treatment. If the spin-off is ultimately determined to be taxable, the Company, Solventum, or the Company’s stockholders could incur income tax liabilities that could be significant. Any of these factors could have a material adverse effect on our business, financial condition, results of operations, cash flows, and the price of our common stock.

Item 1C. Cybersecurity

Risk Management and Strategy

The Company has processes for assessing, identifying, and managing material risks from cybersecurity threats. These processes are integrated into the Company’s overall risk management systems, as overseen by the Company’s board of directors, primarily through its audit committee. These processes also include overseeing and identifying risks from cybersecurity threats associated with the use of third-party service providers. The Company conducts security assessments of certain third-party providers before engagement and has established monitoring procedures in its effort to mitigate risks related to data breaches or other security incidents originating from third parties. The Company from time to time engages third-party consultants, legal advisors, and audit firms in evaluating and testing the Company’s risk management systems and assessing and remediating certain cybersecurity incidents. The Company also continues to provide its employees with cybersecurity and data protection training to support its risk mitigation efforts.

Governance

Board of Directors

The audit committee of the Company’s board of directors oversees, among other things, the adequacy and effectiveness of the Company’s internal controls, including internal controls designed to assess, identify, and manage material risks from cybersecurity threats. The audit committee is informed of material risks from cybersecurity threats pursuant to the escalation criteria as set forth in the Company’s disclosure controls and procedures. Further, at least bi-annually, the Company’s Chief Information and Digital Officer (“CIDO”), and/or the Company’s Chief Information Security Officer (“CISO”), reports on cybersecurity matters, including material risks and threats, to the Company’s audit committee, and the audit committee provides updates to the Company’s board of directors at regular board meetings. The CIDO also provides updates annually or more frequently as appropriate to the Company’s board of directors.

Management

Under the oversight of the audit committee of the Company’s board of directors, and as directed by the Company’s Chief Executive Officer, the CIDO and CISO are primarily responsible for the assessment and management of material cybersecurity risks.The CIDO has more than 20 years of experience with global technology organizations across multiple industries. The CISO has over 25 years of experience in information security, risk management, and compliance, has served as the chief information security officer at other organizations and, among other things, is a certified information systems security professional. The CIDO and CISO are also supported by a Cybersecurity & Privacy Executive Oversight Committee, which is comprised of certain members of senior management and provides cross-functional support for cybersecurity risk management and facilitates the response to any cybersecurity incidents.

The Company’s CISO oversees the Company’s cybersecurity incident response plan and related processes that are designed to assess and manage material risks from cybersecurity threats. The Company’s CISO also coordinates with the Company’s legal counsel and third parties, such as consultants and legal advisors, to assess and manage material risks from cybersecurity threats. The Company’s CISO is informed about and monitors the prevention, detection, mitigation, and remediation of cybersecurity incidents pursuant to criteria set forth in the Company’s incident response plan and related processes.

The Company’s Disclosure Committee, with the assistance of its Cybersecurity Subcommittee, is responsible for overseeing the establishment and effectiveness of controls and other procedures, including controls and procedures related to the public disclosure of material cybersecurity matters. The Company’s Disclosure Committee is comprised of, among others, the Company’s Corporate Controller and Chief Accounting Officer (“CAO”), Treasurer, Chief Legal Affairs Officer (“CLAO”), Assistant Corporate Secretary, General Auditor, and most senior members of the investor relations, external reporting, financial planning and analysis, and tax functions. The Cybersecurity Subcommittee of the Company’s Disclosure Committee is comprised of, among others, the Company’s CAO, Treasurer, CLAO, Assistant Corporate Secretary, and General Auditor, as well as the CIDO and CISO and Chief Privacy Officer.

The Company’s CISO, or a delegate, informs the Disclosure Committee’s Cybersecurity Subcommittee of certain cybersecurity incidents that may potentially be determined to be material pursuant to escalation criteria set forth in the Company’s incident response plan and related processes. The Disclosure Committee’s Cybersecurity Subcommittee is also responsible for advising the Disclosure Committee and the Company’s Chief Executive Officer and Chief Financial Officer regarding cybersecurity disclosures in public filings. The CIDO and CISO, with the CLAO in attendance, also notifies the audit committee chair of any material cybersecurity incident.

As of the date of this Form 10-K, the Company is not aware of any cybersecurity incidents that have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition and that are required to be reported in this Form 10-K. For further discussion of the risks associated with cybersecurity incidents, see the cybersecurity risk factor in the section entitled “Item 1A. Risk Factors” in this Form 10-K.

Overview

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products and services. As discussed in Note 1, certain changes are reflective in this document for all applicable periods presented.

As discussed in Note 2, on April 1, 2024, 3M completed the separation of its Health Care business (the Separation) through a pro rata distribution of 80.1% of the outstanding shares of Solventum Corporation (Solventum) to 3M stockholders. As a result, Solventum became an independent public company, 3M no longer consolidated Solventum into 3M’s financial results and the historical net income of Solventum, and applicable assets and liabilities included in the Separation were reported in 3M's consolidated financial statements as discontinued operations.

3M manages its continuing operations in three operating business segments: Safety and Industrial; Transportation and Electronics; and Consumer. From a geographic perspective, EMEA refers to Europe, the Middle East, and Africa on a combined basis.

Unless otherwise noted, any sales change analysis compares 2025 with 2024, year-on-year (YoY).

Financial highlights for 2025 and 2024:

GAAP Adjusted(a) GAAP Adjusted(a)

Total sales change 1.5 % 2.7 % (0.1) % 1.3 %

Organic sales change(b) 0.9 % 2.1 % (0.2) % 1.2 %

(a) The Company refers to various "adjusted" amounts or measures on an “adjusted" basis. These exclude special items. These non-GAAP measures are further described and reconciled to the most directly comparable GAAP financial measures in the Certain amounts adjusted for special items - (non-GAAP measures) section below.

(b) Organic sales change (which includes both organic volume and selling price impacts), is defined as the change in net sales, absent the impacts from foreign currency translation and acquisitions, net of divestitures. 3M believes this information is useful to investors and management in understanding ongoing operations and in analysis of ongoing operating trends.

Net sales change was driven by strength in safety and general industrial and supported by commercial excellence and new product introductions. These were partially offset by known softness in auto aftermarket, roofing granules, commercial vehicles, and consumer, and the YoY impact of the manufactured PFAS products special item.

GAAP Adjusted(a) GAAP Adjusted(a)

YoY change in operating income margin (1.0) ppts 2.0 ppts 63.0 ppts 2.8 ppts

GAAP operating margins were affected by the YoY impact of special items. These primarily included an increase in net costs for significant litigation impacting operating income from the 2025 PFAS-related New Jersey Settlement and updates to site remediation obligations (discussed in Note 17), partially offset by increased insurance recoveries; manufactured PFAS products impacts; a 2025 charge associated with divestiture activity (discussed in Note 4); and 2025 transformation costs.

Outside of special items, both GAAP and adjusted operating margins reflect benefits from growth, productivity, and lower restructuring costs (apart from the transformation costs special item), partially offset by growth investments and tariff impacts. Additionally, margins YoY were impacted by cost dis-synergies (from the exit of PFAS manufacturing and 2024 spin of Solventum); by transition service agreement reimbursement from Solventum, which began in the second quarter of 2024; and by the lower extent of stock-based compensation grants (see the Certain Expenses Impacting Multiple Line Items within Results of Operation discussion below).

GAAP Adjusted(a) GAAP Adjusted(a)

GAAP EPS YoY was affected by the net impact of special items. In addition to special items relative to operating income discussed above, this primarily included the YOY impact of the change in value of Solventum ownership, a $0.8 billion pre-tax pension settlement charge in 2024 (as discussed in Note 13), and the YOY impact of imputed interest associated with obligations resulting from significant litigation.

Outside of special items, both GAAP and adjusted EPS reflect the impact of the other operating income items discussed above, as well as a 2025 gain on the sale of an investment (see the Income from Unconsolidated Subsidiaries, Net of Taxes discussion below) and the impact of lower share count. These were partially offset by higher non-operating net interest expense and pension expense (both apart from special items).

Table of Contents

3M completed its exit of PFAS manufacturing at the end of 2025 as discussed in Part I, Item 1A, “Risk Factors” of this document. Decisions or circumstances associated with the extent and type of remaining activity at particular locations and impacts on assets and potential obligations, among other factors, could result in additional expenses.

Results of Operations

Net Sales: Percent change information compares 2025 and 2024, unless otherwise indicated. Discussion of business segment results is provided in the Performance by Business Segment section. Information regarding sales by geographic area is included below.

Americas Asia Pacific EMEA Worldwide

Components of net sales change:

Organic sales(b) 1.3 % 1.7 % (1.7) % 0.9 %

Total sales change 1.3 % 1.4 % 2.4 % 1.5 %

Americas Asia Pacific EMEA Worldwide

Components of net sales change:

Organic sales(b) 0.1 % 1.2 % (3.1) % (0.2) %

Acquisitions(c) 0.3 — — 0.2

Total sales change 1.0 % (1.0) % (2.3) % (0.1) %

(c)Acquisition and divestiture sales change impacts are measured separately for the first twelve months post-transaction and, beginning April 2024, include, within divestitures, the impact of commercial agreements associated with the separation of Solventum.

Operating Expenses:

Selling, general and administrative expenses (SG&A) 16.0 17.2 (1.2)

Research, development and related expenses (R&D) 4.7 4.4 0.3

Loss on business divestitures 0.6 — 0.6

Operating income margin 18.6 % 19.6 % (1.0) %

Cost of Sales measured as a percent of sales:Increases in 2025 were primarily due to foreign currency impacts; tariffs; the exit of manufactured PFAS products; and net costs for significant litigation for updates to site remediation obligations partially, offset by ongoing procurement and logistics savings; and quality cost improvement. Additionally, cost of sales in 2025, was impacted by cost dis-synergies (from the exit of PFAS manufacturing and 2024 spin of Solventum). Decreases in 2024 were primarily due to ongoing manufacturing productivity, procurement and logistics savings net of inflation, along with lower YoY restructuring charges compared to 2023. See also Certain Expenses Impacting Multiple Line Items within Results of Operations subsection further below.

SG&Ameasured as a percent of sales: Decreases in 2025 were primarily impacted by lower YoY restructuring charges, ongoing cost discipline and productivity, and benefits from insurance recoveries in 2025. These were partially offset by net costs for significant litigation impacting operating income from the 2025 PFAS-related New Jersey Settlement. Additionally, in 2025, SG&A was impacted by the transition service agreement reimbursement, and cost dis-synergies (from the exit of PFAS manufacturing and 2024 spin of Solventum). Decreases in 2024 were primarily driven by lower YoY net costs for significant litigation and restructuring charges compared to 2023. See also Certain Expenses Impacting Multiple Line Items within Results of Operations subsection further below.

R&Dmeasured as a percent of sales: 3M continues to invest in a range of R&D activities from application development, product and manufacturing support, product development and technology development aimed at disruptive innovations. R&D spending also reflects the Company's continued focus on innovation through growth investments and new product introduction. See also Certain Expenses Impacting Multiple Line Items within Results of Operations subsection further below.

Table of Contents

Loss on Business Divestitures measured as a percent of sales: Applicable information is discussed in Note 4, including a write-down for a business classified as held for sale in 2025.

Other Expense (Income), Net: See Note 7 for a detailed breakout of this line item.

Interest expense (net of interest income): decreased in 2025 compared to the same period YoY and increased in 2024 compared to the same period YoY.

•The decrease in 2025 was impacted by reduced imputed interest associated with obligations resulting from significant litigation (discussed in Note 17) partially offset by lower interest income.

•The increase in 2024 was primarily driven by the addition of imputed interest associated with the obligations resulting from the PWS Settlement and the CAE Settlement in the second and third quarters of 2023, respectively (discussed in Note 17), partially offset by additional interest income.

The non-service pension and postretirement net cost: decreased by approximately $0.7 billion in 2025 and increased by approximately $0.9 billion in 2024.

•These changes were largely due to the $0.8 billion pension settlement charge in 2024, which occurred as a result of transferring a portion of U.S. pension payment obligations and related plan assets to an insurance company (see Note 13). See also Certain Expenses Impacting Multiple Line Items within Results of Operations subsection further below.

Solventum ownership - change in value: decreased by approximately $1.2 billion in 2025 and increased by approximately $1.6 billion in 2024.

Provision for Income Taxes:

Effective tax rate 23.8 % 16.7 %

Adjusted effective tax rate(a) 19.9 19.6

The primary factors that increased the Company's 2025 effective tax rate when compared to 2024 were the tax impact of 3M's retained ownership interest in Solventum and net costs of significant litigation. The primary factors impacting 2024 were the effective tax rate benefit on the change in value of 3M's retained ownership interest in Solventum, offset by the effective tax rate on the PWS Settlement and the CAE Settlement (discussed in Note 17).

Income from Unconsolidated Subsidiaries, Net of Taxes:

Income from unconsolidated subsidiaries, net of taxes $ 52 $ 9

Income from unconsolidated subsidiaries, net of taxes, is attributable to the Company’s accounting under the equity method for ownership interests in certain entities. In 2025, 3M sold its interest in one of these investments, resulting in a pre-tax gain of $47 million. Because this was an ownership disposition, the impact of taxes thereon was reflected separately in provision for income taxes.

Net Income Attributable to Noncontrolling Interest:

Net income attributable to noncontrolling interest $ 12 $ 15

Net income attributable to noncontrolling interest represents the elimination of the income or loss attributable to non-3M ownership interests in 3M consolidated entities. The primary noncontrolling interest relates to 3M India Limited, of which 3M’s effective ownership is 75 percent.

Certain Expenses Impacting Multiple Line Items within Results of Operations:

Stock compensation is discussed in Note 19 and impacts cost of sales, SG&A, and R&D. YoY stock compensation expense was impacted by the lower extent of the 2025 annual grant.

Pre-tax defined benefit pension and postretirement service cost expense impacts cost of sales, SG&A, and R&D while the non-service cost component of pension and postretirement benefits impacts the other expense (income), net line item. Refer to Note 13 for additional information.

On a continuing operations basis, pre-tax stock compensation expense and defined benefit pension and postretirement expense for the periods presented were the following:

Stock compensation expense $ 225 $ 268

Defined benefit pension and postretirement benefit expense

Non-service cost (benefit) 104 828

Total defined pension and postretirement expense $ 272 $ 1,022

In 2024, 3M recorded a non-cash pension settlement charge, part of non-service cost above, as a result of transferring a portion of its U.S. pension payment obligations and related plan assets to an insurance company (as discussed in Note 13).

The Company continues to make investments in the implementation of new business systems and solutions, including enterprise resource planning, with the amortization relating to these investments impacting cost of sales, SG&A, and R&D.

Managing currency risks: 3M utilizes a number of tools to manage the impact of changes in foreign currency exchange rates including natural hedges such as pricing, productivity, hard currency, hard currency-indexed billings, and localizing source of supply. 3M also uses certain derivative instruments (with a tenor up to ten years) and non-derivative instruments to mitigate currency risk. As described in Note 15, these include instruments designated as cash flow hedges, net investment hedges or not designated in formal hedge relationships.

3M’s hedging approach is designed to mitigate a portion of foreign currency risk and reduce volatility, ultimately allowing time for 3M’s businesses to respond to changes in the marketplace.

Raw materials: Refer to the section entitled Raw materials in Item 1 for discussion of 3M's sources and availability of raw materials in 2025.

Pension and postretirement defined benefit plans: On a worldwide basis, 3M’s pension and postretirement plans were 98 percent funded at year-end 2025. The primary U.S. qualified pension plan, which is approximately 62 percent of the worldwide pension obligation, was 94 percent funded and the international pension plans were 124 percent funded. The U.S. non-qualified pension plan is not funded due to tax considerations and other factors. 3M strategically invests in both growth assets and fixed income matching assets to manage its funded status. For the primary U.S. qualified pension plan, the expected long-term rate of return for 2026 is 8.0 percent. The U.S. pension plans' year-end 2025 discount rate was 5.41%, a decrease from the year-end 2024 discount rate of 5.64%. The decrease in U.S. discount rates resulted in an increased valuation of the projected benefit obligation (PBO). Additional detail and discussion of international plan asset returns and discount rates is provided in Note 13 (Pension and Postretirement Benefit Plans).

In 2026, the Company expects to contribute an amount in the range of $100 million to $150 million of cash to its U.S. and international retirement plans. Refer to “Critical Accounting Estimates” within MD&A and Note 13 (Pension and Postretirement Benefit Plans) for additional information concerning 3M’s pension and post-retirement plans.

Performance by Business Segment

Disclosures relating to 3M’s business segments are provided in Note 20. 3M manages its continuing operations in three business segments. The reportable segments are Safety and Industrial; Transportation and Electronics; and Consumer.

Safety and Industrial Business (45.6% of consolidated sales):

Sales change analysis:

Organic sales(b) 3.2 % 0.7 %

Translation 0.7 (0.7)

Total sales change 3.9 % — %

Business segment operating income (millions) $ 2,836 $ 2,491

Percent change 13.9 % 7.2 %

Year 2025 results: Sales in Safety and Industrial were up 3.9 percent in U.S. dollars.

Organic sales increased in electrical markets, industrial adhesives and tapes, personal safety, abrasives and industrial specialties, driven by demand in key underlying markets and commercial excellence; challenges in roofing granules and automotive aftermarket resulted in decreased sales.

Business segment operating income margins increased year-on-year primarily driven by benefits from growth, productivity and lower restructuring costs. These benefits were partially offset by continued growth investments in the business and cost dis-synergies due to the exit of PFAS manufacturing and 2024 spin of Solventum.

Adjusting for special item costs for significant litigation (non-GAAP measure) related to respirator mask/asbestos, business segment operating income margins increased YoY from 23.1 percent to 25.4 percent. Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section below for additional details.

Year 2024 results: Sales in Safety and Industrial were flat in U.S. dollars.

Organic sales increased in roofing granules, industrial adhesives and tapes and in electrical markets due to strong demand for bonding solutions and residential roof replacements, were flat in automotive aftermarket and personal safety, and decreased in industrial specialties and abrasives as industrial end-market demand remained mixed and cautious, including weaker EMEA industrial and manufacturing conditions.

Business segment operating income margins increased year-on-year primarily driven by benefits from growth, productivity and spending discipline partially offset by translation, growth investments and dis-synergies due to the spin of Solventum.

Adjusting for special item costs for significant litigation (non-GAAP measure) related to respirator mask/asbestos, business segment operating income margins increased YoY from 22.0 percent to 23.1 percent. Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section below for additional details.

Table of Contents

Transportation and Electronics Business (33.2% of consolidated sales):

Sales change analysis:

Organic sales(b) (1.5) % (1.0) %

Acquisitions(c) — 0.6

Divestitures(c) (0.1) —

Translation 0.3 (1.0)

Total sales change (1.3) % (1.4) %

Business segment operating income (millions) $ 1,436 $ 1,578

Percent change (9.0) % 20.2 %

Year 2025 results: Sales in Transportation and Electronics were down 1.3 percent in U.S. dollars.

Organic sales increased in commercial branding and transportation and decreased in advanced materials, electronics, and automotive and aerospace, driven by commercial excellence, while growth was negatively impacted by headwinds related to PFAS manufactured products (impacting electronics and advanced materials), the automotive OEM business, and commercial vehicles.

Divestitures:

• Impact relates to the lost sales year-on-year from a divestiture discussed in Note 4.

Business segment operating income margins decreased YoY due to challenging comparison against last year's strong share gains from spec-in wins and new product introductions in automotive and consumer electronics, continued growth investments in the business, and cost dis-synergies due to the exit of PFAS manufacturing and 2024 spin of Solventum, partially offset by benefits from growth, productivity and lower restructuring costs. PFAS manufacturing losses increased YoY as manufacturing concluded in 2025. PFAS manufacturing results were also negatively impacted by updates to depreciable lives and salvage values of remaining treatment-related assets based on site disposition activities.

Adjusted for special item PFAS manufacturing products (non-GAAP measure), sales of $7,603 million were up 2.3 percent YoY in U.S. dollars, or up 2.0 percent organically; while business segment operating income margins decreased YoY from 23.2 percent to 22.7 percent. Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section below for additional details.

Year 2024 results:Sales in Transportation and Electronics were down 1.4 percent in U.S. dollars.

Organic sales increased in electronics driven by new product launches and spec-wins that supported share gains, were flat in commercial branding and transportation, and decreased in advanced materials due to headwinds in PFAS manufactured products (which also negatively impacted electronics) and in automotive and aerospace from lower automotive OEM build rates.

Acquisitions/divestitures:

•Divestiture and acquisition impacts relate to lost/gained Transportation and Electronics sales year-on-year from the Aearo Entities. In the third quarter of 2022, 3M deconsolidated the Aearo Entities and, in the second quarter of 2023, reconsolidated those entities. For each of the 12-months post-deconsolidation and post-reconsolidation, impacts are each reflected separately as divestiture and acquisition, respectively.

Business segment operating income margins increased year-on-year driven by benefits from non-PFAS manufacturing growth and productivity, spending discipline, and restructuring partially offset by dis-synergies due to the spin of Solventum. Margins were also impacted by decreased PFAS manufacturing.

Adjusting for special item PFAS manufactured products (non-GAAP measure), sales of $7,435 million were up 3.1 percent YoY in U.S. dollars, or up 3.4 percent organically; while business segment operating income margins increased YoY from 21.0 percent to 23.2 percent. Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section below for additional details.

Table of Contents

Consumer Business (19.7% of consolidated sales):

Sales change analysis:

Organic sales(b) (0.3) % (1.2) %

Translation 0.1 (0.7)

Total sales change (0.2) % (1.9) %

Business segment operating income (millions) $ 996 $ 932

Percent change 6.9 % 3.1 %

Year 2025 results: Sales in Consumer were down 0.2 percent in U.S. dollars.

Organic sales increased in consumer safety and well-being and home and auto care, driven by new product launches, service improvements, and increased advertising and merchandising investment; while soft consumer discretionary spending contributed to flat sales in home improvement and decreased sales in packaging and expression.

Business segment operating income margins increased YoY driven by benefits from growth, productivity, and lower restructuring costs partially offset by continued growth investments in the business and cost dis-synergies due to the exit of PFAS manufacturing and 2024 spin of Solventum.

Year 2024 results:Sales in Consumer were down 1.9 percent in U.S. dollars.

Organic sales increased in home improvement, and decreased in home and auto care, packaging and expression and consumer safety and well-being, driven by softness in consumer discretionary spending along with product portfolio and geographic prioritization.

Business segment operating income margins increased year-on-year driven by benefits from productivity actions, portfolio initiatives, and spending discipline partially offset by organic decline and dis-synergies due to the spin of Solventum.

Corporate and Other: Outside of 3M's reportable segments, 3M has Corporate and Other which is not a reportable business segment as it does not meet the segment reporting criteria. Because Corporate and Other includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis. Corporate and Other is further described in Note 20.

Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section below and Note 20 for details on the components of corporate special items and their impact. Corporate-level income, net, increased YoY in 2025, primarily due to the extent of transition arrangement income from divested businesses (and associated costs) largely related to Solventum's April 2024 Separation as well as the extent of non-discontinued operations-eligible former Solventum-allocated costs included in Corporate and Other prior to the Separation. Corporate-level expense, net, decreased YoY in 2024, primarily due to the extent of non-discontinued operations-eligible former Solventum-allocated costs included in Corporate and Other prior to Solventum's April 2024 Separation.

Performance by Geographic Area

While 3M manages its businesses globally and believes its business segment results are the most relevant measure of performance, the Company also utilizes geographic area data as a secondary performance measure. Export sales are generally reported within the geographic area where the final sales to 3M customers are made. A portion of the products or components sold by 3M’s operations to its customers are exported by these customers to different geographic areas. As customers move their operations from one geographic area to another, 3M’s results will follow. Thus, net sales in a particular geographic area are not indicative of end-user consumption in that geographic area. Financial information related to 3M operations in various geographic areas is provided in Note 3 and Note 20.

Refer to the Overview section for a summary of net sales by geographic area and business segment.

Table of Contents

Geographic Area Supplemental Information

Employment: Employment decreased in 2025 when compared to 2024. The above table, as applicable, includes the impact of acquisitions, net of divestitures, and other actions.

Capital Spending/Property, Plant and Equipment - Net: Amounts relative to these items in the above table relate to 3M's continuing operations and do not include amounts associated with discontinued operations (refer to Note 2 for the amount attributed to discontinued operations).YoY changes in capital spending primarily reflect the timing of project execution and the scale of underlying initiatives. Capital spending is also discussed later in MD&A in the section entitled Cash Flows from Investing Activities.

Certain amounts adjusted for special items - (non-GAAP measures)

In addition to reporting financial results in accordance with U.S. GAAP, 3M also provides certain non-GAAP measures. These measures are not in accordance with, nor are they a substitute for GAAP measures, and may not be comparable to similarly titled measures used by other companies.

Certain measures adjust for the impacts of special items. Special items for the periods presented include the items described in the section entitled “Description of special items”. Because 3M provides certain information with respect to business segments, it is noteworthy that special items impacting operating income (loss) are reflected in Corporate and Other, except as described with respect to net costs for significant litigation and manufactured PFAS products items in the “Description of special items” section. The reconciliations below, therefore, also include impacted segments as applicable.

This document contains measures for which 3M provides the reported GAAP measure and a non-GAAP measure adjusted for special items. The document also contains additional measures which are not defined under U.S. GAAP. These measures and reasons 3M believes they are useful to investors (and, as applicable, used by 3M) include:

•Income from continuing operations before taxes

•Provision for income taxes and effective tax rate

•Net income from continuing operations

•EPS from continuing operations

Special items for the periods presented include:

Net costs for significant litigation:

•These relate to 3M's respirator mask/asbestos (which include Aearo and non-Aearo items), PFAS-related other environmental, and Combat Arms Earplugs matters (as discussed in Note 17). Net costs include the impacts of changes in accrued liabilities (including interest imputation on applicable settlement obligations), legal costs, and insurance recoveries, along with the associated tax impacts. Associated tax impacts of significant litigation include impacts on Foreign Derived Intangible Income (FDII), Global Intangible Low Taxed Income (GILTI), foreign tax credits, and tax costs of repatriation. 3M does not consider the elements of the net costs associated with these matters to be normal, operating expenses related to the Company’s ongoing operations, revenue generating activities, business strategy, industry, and regulatory environment. Net costs related to respirator mask/asbestos are reflected as special items in the Safety and Industrial business segment while those impacting operating income (loss) associated with PFAS-related other environmental and Combat Arms Earplugs matters are reflected as corporate special items in Corporate and Other.

Table of Contents

Gain/loss on business divestitures:

•In 2025, 3M reflected a net write-down for a business classified as held for sale and completed a divestiture for immaterial proceeds slightly below the business's book value. In 2023, 3M recorded a gain related to the sale of its dental local anesthetic business partially offset by a loss associated with a contingent indemnification obligation from an earlier divestiture. See Note 4 for additional information.

Divestiture costs:

•These include limited costs that were not eligible to be included within discontinued operations related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture. As a result of completion of the April 2024 separation of Solventum, this includes the tax cost of updating 3M’s previous indefinite reinvestment plans on past unrepatriated earnings through the period of the Separation’s close and to tax positions retained by 3M.

Manufactured PFAS products:

•These amounts relate to sales and estimates of income (loss) regarding manufactured PFAS products that 3M exited by the end of 2025, included within the Transportation and Electronics business segment. Estimated income does not contemplate impacts on non-operating items such as net interest income/expense and the non-service cost components portion of defined benefit plan net periodic benefit costs.

Russia exit benefits:

•In 2023, 3M recorded a gain on final disposal of net assets in Russia.

Pension risk transfer charge:

•In 2024, 3M recorded a non-cash pension settlement charge reflected in other expense (income), net as a result of transferring a portion of its U.S. pension payment obligations and related plan assets to an insurance company (as discussed in Note 13).

Solventum ownership - change in value:

•This amount relates to the change in value of 3M's retained ownership interest in Solventum common stock reflected in other expense (income), net.

Transformation costs:

•These represent net costs associated with 3M's transformation program, intended as a structural redesign of longer-term manufacturing, distribution, and business process services and locations. Accordingly, 3M does not consider the nature or effect of this program to be normal, operating expenses related to the Company’s ongoing operations, revenue generating activities, and day-to-day business strategy. Net costs include restructuring and other related items such as site closure, sale, moving and set-up, accelerated depreciation, and program management.

Amounts from continuing operations

Safety and Industrial
