3M CO

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products and services. Certain changes are reflective in this document for all applicable periods presented. These include:

•As discussed in Note 2, on April 1, 2024, 3M completed the previously announced 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 of the Separation, Solventum became an independent public company and 3M no longer consolidates Solventum into 3M’s financial results. In connection with the Separation, the historical net income of Solventum and applicable assets and liabilities included in the Separation are reported in 3M's consolidated financial statements as discontinued operations.

•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 as further described in Note 19. To the extent these changes impacted 3M's disclosed disaggregated revenue information, data in Note 3 has also been updated.

3M manages its continuing operations in three operating business segments: Safety and Industrial; Transportation and Electronics; and Consumer. From a geographic perspective, any references to EMEA refer to Europe, Middle East and Africa on a combined basis. References are made to organic sales change (which include both organic volume impacts and selling price impacts), which is defined as the change in net sales, absent the separate impacts on sales from foreign currency translation and acquisitions, net of divestitures. Acquisition and divestiture sales change impacts, if any, are measured separately for the first twelve months post-transaction and, beginning April 2024, include the impact of commercial agreements associated with the separation of Solventum. 3M believes this information is useful to investors and management in understanding ongoing operations and in analysis of ongoing operating trends.

3M is impacted by certain special items such as costs for significant litigation and the sales and income associated with manufactured PFAS products. See Certain amounts adjusted for special items - (non-GAAP measures) section below for additional discussion of these and other special items, including references therein to where further information is provided.

Additional information regarding certain items impacting pre-2024 periods that may also be relevant in 2024 can be found in the Overview section of Part II, Item 7 as well as in further sections of 3M’s 2023 Annual Report on Form 10-K.

Earnings (loss) from continuing operations per share attributable to 3M common shareholders – diluted: The following table provides the increases (decreases) in diluted earnings (loss) from continuing operations per share.

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.

A discussion related to the components of year-on-year changes in earnings (loss) from continuing operations per diluted share follows:

Total organic growth/productivity and other:

•For the second quarter of 2024, the following components impacted operating margins and earnings (loss) from continuing operations per diluted share year-on-year:

◦Timing of stock-based compensation grants to be incurred in the second quarter of 2024 versus the first quarter of 2023 due to Solventum spin (further discussed in "Results of Operations" section) resulted in a net year-on-year headwind of $0.18 per share.

◦Income from transition service agreements with Solventum (refer to Note 2 for additional discussion) resulted in a net year-on-year increase of $0.05 per share

◦Remaining organic growth/productivity and other impacts resulted in a net year-on-year increase of $0.31 per share which was impacted by the following:

▪Benefits from volume growth, productivity, spending discipline and restructuring

•For the first six months of 2024, the following components impacted operating margins and earnings (loss) from continuing operations per diluted share year-on-year:

◦Nonrecurring items including gain on property sales resulted in a net year-on-year increase of $0.08 per share.

◦Income from transition services agreements with Solventum (refer to Note 2 for additional discussion) resulted in a net year-on-year increase of $0.05 per share

◦Remaining organic growth/productivity and other impacts resulted in a net year-on-year increase of $0.65 per share which was impacted by the following:

▪Benefits from productivity, volume growth, sourcing actions, spending discipline and restructuring

▪Investments in growth, productivity, and sustainability

Restructuring and related charges:

•3M recorded restructuring pre-tax charges of $35 million and $138 million in the second quarter and first six months of 2024, respectively, compared to $202 million and $252 million in the same periods last year, respectively, (refer to Note 6 for additional discussion). In addition, 3M recorded certain related accelerated depreciation.

Foreign exchange impacts:

•Foreign currency impacts (net of hedging) decreased operating income from continuing operations by approximately $24 million (or a decrease of pre-tax income from continuing operations by approximately $31 million) year-on-year for the second quarter of 2024 and decreased operating income from continuing operations by approximately $73 million (or a decrease of pre-tax income from continuing operations by approximately $82 million) year-on-year for the first six months of 2024. These estimates include: (a) the effects of year-on-year changes in exchange rates on translating current period functional currency profits into U.S. dollars and on current period non-functional currency denominated purchases or transfers of goods between 3M operations, and (b) year-on-year changes in transaction gains and losses, including derivative instruments designed to reduce foreign currency exchange rate risks.

Acquisitions/divestitures:

•Impacts relate to:

◦Divestiture impacts include the effect of new commercial agreements associated with the April 2024 separation of Solventum.

◦Reconsolidation of Aearo entities - in the third quarter of 2022, 3M deconsolidated the Aearo Entities and, in the second quarter of 2023, reconsolidated those entities (discussed in Note 17). For each of the 12-months post-deconsolidation and post-reconsolidation, impacts are each reflected separately as divestiture and acquisition, respectively.

Other expense (income), net:

•Interest expense (net of interest income) included in other expense (income), net as presented above decreased for the second quarter and first six months of 2024 compared to the same period year-on-year.

•Lower income related to non-service cost components of pension and postretirement expense increased expense year-on-year for the second quarter and first six months of 2024.

Income tax rate:

•Certain items above reflect specific income tax rates associated therewith. Overall, the effective tax rate for the second quarter of 2024 was 14.4 percent on a pre-tax income, compared to 24.0 percent on pre-tax loss in the prior year. The effective tax rate for the first six months of 2024 was 18.1 percent, compared to 24.6 percent in the prior year. The primary factors that impacted the comparison of these rates year-over -year were the second quarter 2023 charge related to the settlement agreement with public water systems in the United States regarding PFAS (see Note 17) and the tax rate associated with second quarter 2024 benefit related to the change in value of the retained ownership interest in Solventum.

•On an adjusted basis (as discussed below), the effective tax rate for the second quarter and first six months of 2024 was 19.1% and 19.9%, respectively, a decrease of 0.4 percentage points and an increase of 1.2 percentage points, respectively, compared to the same period year-on-year.

Shares of common stock outstanding:

•Shares outstanding did not significantly impact earnings (loss) from continuing operations per share year-on-year for the second quarter and first six months of 2024.

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 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:

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), external legal fees, 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), and foreign tax credits. 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 Unallocated. In addition, during the voluntary chapter 11 bankruptcy period (which began in July 2022 and ended in June 2023—see Note 17), costs associated with the Aearo portion of respirator mask/asbestos matters were reflected in corporate special items in Corporate and Unallocated. Prior to the bankruptcy, costs associated with Combat Arms Earplugs matters were reflected as part of special items in the Safety and Industrial business segment.

Divestiture costs:

•These include certain 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 update to 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 plans to exit by the end of 2025 included within the Transportation and Electronics business segment. Along with other costs in arriving at this associated income, these amounts include estimates of costs of sales of $186 million and $233 million for the three months ended June 30, 2024 and 2023, respectively, and $416 million and $509 million for the six months ended June 30, 2024 and 2023, respectively. 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 charges/benefits:

•In the second quarter of 2023, 3M recorded a gain on final disposal of net assets in Russia. Previously, in the third quarter of 2022, 3M recorded a charge primarily related to impairment of these assets in connection with management's committed exit and disposal plan.

Pension risk transfer charge:

•In the second quarter of 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.

3 For 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.

Sales and operating income (loss) by business segment: The following tables contain sales and operating income (loss) results by business segment for the three and six months ended June 30, 2024 and 2023. Refer to the section entitled Performance by Business Segment later in MD&A for additional discussion concerning 2024 versus 2023 results, including Corporate and Unallocated and Other. Corporate and Unallocated and Other are not reportable business segments as they do not meet the segment reporting criteria. Refer to Note 19 for additional information on business segments.

Refer to the Certain amounts adjusted for special items - (non-GAAP measures) section for additional details on the impact of special items on sales (and sales change) and operating income (loss) by business segment.

Sales by geographic area: Percent change information compares the three and six months ended June 30, 2024 with the same prior year period, unless otherwise indicated. Additional discussion of business segment results is provided in the Performance by Business Segment section.

In November 2018, 3M’s Board of Directors replaced the Company’s February 2016 repurchase program with a new repurchase program. This new program authorizes the repurchase of up to $10 billion of 3M’s outstanding common stock, with no pre-established end date. In the first six months of 2024, the Company purchased $421 million of its own stock, compared to $29 million of stock purchases in the first six months of 2023. As of June 30, 2024, approximately $3.8 billion remained available under the authorization. In February 2024, 3M’s Board of Directors declared a first-quarter 2024 dividend of $1.51 per share.
