BUSINESS SEGMENTS

(Unaudited)

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”).

Effective in the first and second quarters of 2026, the measure of segment operating performance and segment composition used by 3M’s chief operating decision maker (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 first quarter 2026—manufactured PFAS productsactivity 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.

•Effective second quarter 2026—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.

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),

◦business acquisition-related costs,

◦manufactured PFAS products activity,

◦(loss) gain on business divestitures, and

◦transformation program restructuring and related charges.

NON-GAAP MEASURES

(Unaudited)

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 impact 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.

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:

GAAP amounts for which a measure adjusted for special items is also provided:	Reasons 3M believes the measure is useful:
•Net sales (and sales change)	Considered in evaluating and managing operations; useful in understanding underlying business performance, provides additional transparency to special items
•Operating income (loss) and operating income (loss) margin (and expansion)
•Income before taxes
•Provision for income taxes and effective tax rate
•Net income
•EPS

Additional non-GAAP measures:
•Adjusted net cash provided by (used in) operating activities; adjusted purchases of property, plant and equipment (also referred to as adjusted capital expenditures); adjusted free cash flow and adjusted free cash flow conversion	Used as indicators of strength and ability to generate cash and as indicator of capital deployment; meaningful as measures of performance

The following provides additional information and applicable GAAP amounts reconciled to non-GAAP measures.

53M provides these forward-looking non-GAAP measures, but cannot, without unreasonable effort, forecast certain items to present or provide a reconciliation to corresponding forecasted GAAP measures. These include special items such as net costs for significant litigation and PFAS exit; business acquisition-related costs; projected divestiture gains (losses); changes in value of Solventum ownership; transformation costs; and net sales and estimates of income and associated activity of exited manufactured PFAS products all of which are subject to limitations in predictability of timing, ultimate outcome and numerous conditions outside of 3M’s control. 3M believes these limitations would result in a range of projected values so broad as to not be meaningful to investors. For these reasons, 3M believes that the probable significance of such information is low. Additionally, for similar reasons, 3M does not include the impact of potentially-divested or acquired businesses on expected operations in forecasted guidance it provides until close of a transaction, unless otherwise indicated. Information with respect to special items for certain historical periods is included in the section entitled “Description of special items”.

63M defines adjusted net cash provided by (used in) operating activities as net cash provided by operating activities, adjusted for special items. 3M defines adjusted purchases of property, plant and equipment (also referred to as adjusted capital expenditures) as purchases of property, plant and equipment (PPE) adjusted for the estimated impact of such purchases associated with manufactured PFAS products activity. 3M defines adjusted free cash flow as adjusted net cash provided by (used in) operating activities less adjusted purchases of PPE. Cash payments/receipts associated with special items in the determination of adjusted net cash provided by (used in) operating activities are reflected net of applicable tax. The cash tax impact is determined by the amount, timing, and applicable tax rates for the actual cash tax payments, which may differ from the timing of the related pre-tax cash payments or underlying transactions. 3M defines adjusted free cash flow conversion as adjusted free cash flow divided by net income attributable to 3M, adjusted for special items (used for adjusted free cash flow conversion calculation).

Description of special items:

In addition to reporting financial results in accordance with U.S. GAAP, the Company also provides various non-GAAP measures that incorporate adjustments for the impacts of special items. Special items incorporated in the preparation of these non-GAAP measures for the periods presented include the items described below:

Net costs for significant litigation and PFAS exit:

•Net costs for significant litigation relate to 3M's respirator mask/asbestos (which include Aearo and non-Aearo items), PFAS-related other environmental, and Combat Arms Earplugs matters. 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 Deduction Eligible Income ("FDDEI"), Net Controlled Foreign Corporation Tested Income ("NCTI"), foreign tax credits, and tax costs of repatriation. PFAS exit costs include amounts outside of significant litigation related to impacted site disposition and treatment post-first quarter 2026 completion of substantive PFAS product sales. 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. In the second quarter of 2026 and 2025, 3M reflected net pre-tax cash (receipts)/payments of $858 million and $2,509 million, respectively, related to net costs for significant litigation and PFAS exit. In the first six months of 2026 and 2025, 3M reflected net pre-tax cash (receipts)/payments of $960 million and $3,315 million, respectively, related to net costs for significant litigation and PFAS exit.

Business acquisition-related costs:

•These include transaction and integration costs as applicable in the respective periods.

Gain/loss on business divestitures:

•In the third quarter of 2025, 3M classified a business as held for sale. In the first half of 2026, 3M reflected an adjustment to carrying it at its selling price less cost to sell. In the second quarter of 2026, 3M recorded a loss on the divestiture of its Dyneon GmbH subsidiary. In June 2025, 3M completed a divestiture for immaterial proceeds slightly below the business’ 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.

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.

Russia exit benefits

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

Manufactured PFAS products:

•These amounts relate to sales and income (loss) and associated activity regarding manufactured PFAS products that 3M exited by the end of 2025. 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. Relative to the impact of the activity of manufactured PFAS products on cash provided by (used in) operating activities, amounts are based on estimates of associated income, depreciation, certain changes in working capital and accruals, and timing of associated payments.

Enactment/measurement period adjustments related to the Tax Cuts and Jobs Act (TCJA):

•In the second quarter of 2025, 3M made payments of $211 million related to the transition tax expense incurred as a result of the 2017 enactment of the TCJA.

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. In the second quarter and first six months of 2026, 3M made pre-tax cash payments of $41 million and $73 million, respectively, associated with transformation costs.
