2As further discussed at 6 within the "Supplemental Financial Information Non-GAAP Measures" sections, 3M cannot, without unreasonable effort, forecast certain items required to develop meaningful comparable GAAP financial measures and, therefore, does not provide them on a forward-looking basis reflecting these items.

A further description of these factors is located in the Reports under “Cautionary Note Concerning Factors That May Affect Future Results” and “Risk Factors” in Part I, Items 1 and 1A (Annual Report) and in Part I, Item 2 and Part II, Item 1A (Quarterly Reports). Changes in such assumptions or factors could produce significantly different results. The Company assumes no obligation to update any forward-looking statements discussed herein as a result of new information or future events or developments.

The Consolidated Statements of Cash Flows include the results of continuing and discontinued operations and, therefore, also include cash and cash equivalents associated with Solventum through its April 2024 separation from 3M that were presented in current assets of discontinued operations in the 3M Consolidated Balance Sheet.

3Total 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 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:

•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.

•3M added the “Other” category of information as a result of the Separation. It principally reflects activity associated with:

•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 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.

•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.

•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.

Outside of 3M's 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 and Russia exit costs/ 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 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:

The table below provides disaggregated revenue information for full-year 2023 revised to reflect the changes to composition of segment information 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. Similar information relative to applicable periods will be included in 3M’s Form 10-Q filed for the second quarter of 2024. The information below should be read together with information in 3M’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024, Annual Report on Form 10-K for the year ended December 31, 2023, and Quarterly Reports on Form 10-Q during the year ended December 31, 2023 (including the consolidated financial statements, notes thereto and Management’s Discussion and Analysis included in those documents), along with information included in 3M’s Current Reports on Form 8-K filed April 4, 2024. The financial information that follows does not revise or otherwise amend or restate any previously filed financial information of 3M. This information is preliminary, unaudited, and based on current estimates, and remains subject to change.

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:

4These items represent amounts adjusted for special items. See lead-in to non-GAAP measures discussion.

5For the per share amount, this includes adjusting-out the impact of this item causing weighted average shares outstanding to be the same for both basic and diluted loss per share in periods of resulting net losses.

63M 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; projected divestiture gains; divestiture costs; divestiture-related restructuring; changes in value of Solventum ownership; 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 outlook guidance it provides until close of a transaction. Information with respect to special items for certain historical periods is included in the section entitled “Description of special items”.
