SALES CHANGE ANALYSIS4

4Total sales change is calculated based on reported sales results. The components of sales change include organic local-currency sales, acquisitions, divestitures, and translation. Organic local-currency sales include both organic volume impacts (which excludes acquisition and divestiture impacts) and selling price changes. Acquisition and divestiture impacts are measured separately for the first 12 months post-transaction and, beginning April 2024, include the impact of commercial agreements associated with the separation of Solventum.

3M Company and Subsidiaries

3M discloses business segment operating income (loss) as its measure of segment profit loss, reconciled to both total 3M operating income (loss) and income before taxes. Business segment operating income (loss) excludes certain expenses and income that are not allocated to business segments (as described below in "Corporate and Unallocated and Other").

3M made certain changes to the composition of segment information reviewed by 3M's chief operating decision maker (CODM) effective in the second quarter of 2024 largely as a result of the separation of Solventum and changes within its business segments effective in the first quarter of 2024. Accordingly, information provided herein reflects the impact of these changes for all applicable periods presented.

Effective in the second quarter of 2024, this change included the following

Elimination of former Health Care business segment

The former Health Care business segment was eliminated in the second quarter of 2024 in connection with the separation of Solventum and reflection of its historical net income and applicable assets and liabilities included in the Separation as discontinued operations within 3M's financial statements.

Addition of Other' and update to Corporate and Unallocated'

3M added the "Other" category of information as a result of the Separation. It principally reflects

Transition arrangement agreements (e.g. fees charged by 3M, net of underlying costs) related to divested businesses, including those related to the Separation, as well as other applicable divestitures.

Operations of businesses of the former Health Care segment divested prior to the Separation and therefore not reflected as discontinued operations within 3M's financial statements, along with limited-duration supply agreements with those previous divestitures.

Activity included in 3M's existing "Corporate and Unallocated" was updated primarily to additionally reflect

Removal of costs related to separating and divesting Solventum that were not eligible to be part of discontinued operations.

Commercial activity with Solventum post-Separation and certain operations of the former Health Care business segment retained by 3M.

Costs previously allocated to Solventum prior to the Separation that were not eligible to be part of discontinued operations (and prospectively, post-spin, became additional costs allocated to remaining business segments) other than those beginning in the first quarter of 2024 included in "Other" associated with transition arrangement activity for which 3M began to charge fees in April 2024.

In addition, effective in the first quarter of 2024, 3M made certain changes within its business segments as described below. While they impacted the composition of certain divisions within business segments, they did not change the overall composition of segments or the measure of segment operating performance used by 3M's CODM.

Creation of Industrial Specialties division (within Safety and Industrial business segment) and Commercial Branding and Transportation division (within Transportation and Electronics business segment)

3M created the Industrial Specialties division within the Safety and Industrial business segment, which consists of the former Closure and Masking Systems division along with certain products formerly within the Industrial Adhesive and Tapes division and the Personal Safety division. Further, 3M created the Commercial Branding and Transportation division within the Transportation and Electronics business segment, which consists of the former Commercial Solutions division and the Transportation Safety division.

Re-alignment of divisions within Consumer business segment

Within the Consumer business segment, the business re-aligned to the following four divisions Consumer Safety and Well-Being, Home and Auto Care, Home Improvement, and Packaging and Expression.

BUSINESS SEGMENTS - (CONTINUED)

Corporate and Unallocated and Other

Outside of 3M's reportable operating segments, 3M has Corporate and Unallocated and Other which are not reportable business segments as they do not meet the segment reporting criteria. Because Corporate and Unallocated and Other include a variety of miscellaneous items, they are subject to fluctuation on a quarterly and annual basis.

Corporate and Unallocated operating income (loss) includes "corporate special items" and "other corporate expense-net".

Corporate special items include net costs for significant litigation impacting operating income (loss) associated with PFAS-related other environmental and Combat Arms Earplugs matters. In addition, during the voluntary chapter 11 bankruptcy period (which began in July 2022 and ended in June 2023), costs associated with the Aearo portion of respirator mask asbestos matters were also included in corporate special items. Prior to the bankruptcy, costs associated with Combat Arms Earplugs matters were not included in the Corporate net costs for significant litigation special item, instead being reflected in the Safety and Industrial business segment. Corporate special items for the periods presented also include divestiture costs, gain on business divestitures, and Russia exit charges benefits. Divestiture costs include costs that were not eligible to be part of discontinued operations related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture.

Other corporate expense-net includes certain enterprise and governance activities resulting in unallocated corporate costs and other activity and net costs that 3M may choose not to allocate directly to its business segments. Other corporate expense-net also includes costs previously allocated to Solventum prior to the

BUSINESS SEGMENTS - (CONTINUED)

Separation that were not eligible to be part of discontinued operations, commercial activity with Solventum post-Separation, and certain operations of the former Health Care business segment retained by 3M.

Other principally reflects activity associated with

Operations of businesses of the former Health Care segment divested prior to the Separation and therefore not reflected as discontinued operations within 3M's financial statements, along with limited-duration supply agreements with those previous divestitures.

Transition arrangement agreements (e.g. fees charged by 3M, net of underlying costs) related to divested businesses, including those related to the Separation, as well as other applicable divestitures.

SUPPLEMENTAL FINANCIAL INFORMATION

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 Unallocated, 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
