Business Segments
Note 16. Business Segments
3M’s businesses are organized and managed in three business segments: Safety and Industrial; Transportation and Electronics; and Consumer — based on differences in markets, products, technologies and services. These segments bring together related 3M technologies, enhance innovation and provide efficient resource sharing. As an integrated enterprise, 3M has substantial intersegment cooperation, cost allocations and inventory transfers. Accordingly, management does not represent that these segments, if operated independently, would report the operating income information shown.
3M discloses business segment operating income as its measure of segment profit, which is reconciled to both total 3M operating income and income before taxes. This measure excludes certain expenses and income not allocated to business segments (as described below in “Corporate”). Business segment disclosures consider information used by/provided to 3M's CODM, who is the chief executive officer. The CODM uses business segment operating income to allocate resources in the planning and forecasting process and in reviews of results and overall market activity.
In 2026, the measure of segment operating performance and segment composition used by the CODM changed. As a result, 3M’s disclosed measure of segment profit and other segment-related amounts were updated to reflect these changes for all periods presented. The changes include the following items now reflected within Corporate:
•Effective third quarter 2026 - acquired intangible asset amortization: This is now reflected as a Corporate special item rather than within reportable business segment operating income.
•Effective earlier in 2026:
◦Manufactured PFAS products activity and net costs for respirator mask/asbestos litigation special items: These special items were moved into Corporate from the Transportation and Electronics segment and Safety and Industrial segment, respectively.
◦Business acquisition-related costs: These costs are now reflected as a Corporate special item rather than within reportable business segment operating income. There were no such material costs in prior periods presented.

"Business segment assets" represent inventories, based on the extent of business segment information regularly provided to 3M's CODM.
Business segment depreciation reflected above is based on the underlying usage of assets and allocated depreciation.
Corporate: Outside of 3M's reportable segments, 3M has Corporate which is not a reportable business segment as it does not meet the segment reporting criteria. Because Corporate includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis.
Corporate operating income (loss) includes:
•Corporate-level (expense) income includes:
◦certain enterprise and governance activities resulting in unallocated corporate costs and other activity or costs that 3M may choose not to allocate directly to its business segments,
◦commercial activity with Solventum following its April 2024 spin-off from 3M, as well as certain operations of 3M’s former health care business segment that were retained by 3M, and
◦transition arrangement agreements (e.g., fees charged by 3M, net of underlying costs) related to divested businesses, including those related to Solventum.
•Corporate special items include, for the periods presented:
◦net costs for significant litigation and PFAS exit impacting operating income (loss),
◦acquired intangible asset amortization and business acquisition-related costs,
◦manufactured PFAS products activity,
◦(loss) gain on business divestitures (see Note 3), and
◦transformation program restructuring (see Note 5) and related charges.
