Proactive Initiatives Drive Strong Quarterly Financial Results Raises Full-Year Adjusted EPS Guidance

ST. PAUL, Minn. - July 25, 2023 3M (NYSE MMM) today reported second quarter 2023 results.

"In the second quarter, the actions we took to strengthen our supply chain and restructure the company led to improved service for customers, reduced costs across 3M, and better than expected margins and cash flow, said Mike Roman, 3M chairman and chief executive officer. "As we execute our strategy, we are positioning 3M for long-term performance, including progressing the planned spin of our Health Care business and addressing a significant portion of PFAS litigation."

Second Quarter Highlights

GAAP loss per share of $12.35 and operating margin of minus 107.6% include the previously announced proposed settlement agreement with PWS in the United States regarding PFAS resulting in a pre-tax charge of $10.3 billion payable over 13 years, negatively impacting earnings per share by $14.19.

Adjusted earnings per share of $2.17 includes pre-tax restructuring charges of $212 million, or negative $0.31 per share.

Adjusted operating income margin of 19.3% includes a 2.7 percentage point headwind from pre-tax restructuring charges.

Sales of $8.3 billion, down 4.3 percent year-on-year, with organic sales decline of 2.2 percent year-on-year.

Adjusted sales of $8.0 billion, down 4.7 percent year-on-year with adjusted organic sales decline of 2.5 percent year-on-year.

Operating cash flow of $1.5 billion, up 34 percent year-on-year adjusted free cash flow of $1.5 billion, up 44 percent year-on-year.

3M returned $828 million to shareholders via dividends.

The above includes reference to certain non-GAAP measures. See the "Supplemental Financial Information Non-GAAP Measures" section for applicable information.

Full-Year 2023 Outlook

Given the company's strong operational execution and cost discipline, 3M raises its full-year adjusted EPS2 expectations for 2023 to $8.60 to $9.10 vs. $8.50 to $9.00 prior.

Adjusted total sales growth2 in the range of -5 to -1 percent, reflecting adjusted organic sales growth of -3 percent to flat, which remains unchanged.

Adjusted operating cash flow2 of $5.9 to $6.3 billion is contributing to 90% to 100% adjusted free cash flow conversion2,which is also unchanged.

2As further discussed at 6 within the Supplemental Financial Information Non-GAAP Measures section, 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.

3M Resolves Claims by PWS in the United States

On June 22, 2023, 3M issued a press release announcing a proposed settlement agreement with PWS in the United States regarding PFAS. As a result of this agreement, 3M recorded a pre-tax charge of $10.3 billion in the second quarter of 2023. The charge reflects the present value of the expected $12.5 billion nominal value of 3M's payments over 13 years under the agreement.

SALES CHANGE ANALYSIS3

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.

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 (loss) 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").

Effective in the first quarter of 2023, the measure of segment operating performance and segment composition used by 3M's chief operating decision maker (CODM) changed and, as a result, 3M's disclosed measure of segment profit loss (business segment operating income (loss)) was updated. The change to business segment operating income (loss) aligns with the update to how the CODM assesses performance and allocates resources for the Company's business segments. The changes included the items described below. The financial information presented herein reflects the impact of these business segment reporting changes for all periods presented.

Reflecting gains losses from sale of property, plant and equipment (PPE) and other assets within Corporate and Unallocated Change

3M updated its business segment operating performance measure to reflect all gains losses from sales of PPE and other assets within Corporate and Unallocated. Previously, certain of these gains losses were included in 3M's business segments' operating performance.

Movement of certain businesses between segments

The businesses associated with two groups of products (each with approximately $25 million in sales) were realigned with one moving from the Consumer business segment to the Health Care business segment and the other moving from the Health Care business segment to the Consumer business segment.

Also effective in the first quarter of 2023, the Consumer business segment re-aligned from four divisions to the following three divisions Home, Health and Auto Care Construction and Home Improvement Markets and Stationery and Office.

BUSINESS SEGMENTS - (CONTINUED)

Corporate and Unallocated

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 also include divestiture costs, gain loss on business divestitures, divestiture-related restructuring costs, and Russia exit costs benefits. Divestiture costs include costs related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture. Other corporate expense-net includes items such as net costs related to limited unallocated corporate staff and centrally managed material resource centers of expertise costs, corporate philanthropic activity, gains losses from sales of PPE and other assets, and other net costs that 3M may choose not to allocate directly to its business segments. Other corporate expense-net also includes costs and income from transition supply, manufacturing, and service arrangements with Neogen Corporation following the 2022 split-off of 3M's Food Safety business. Items classified as revenue from this activity are included in Corporate and Unallocated net sales. Because Corporate and Unallocated includes a variety of miscellaneous items, it is subject to fluctuation on a quarterly and annual basis.

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.

In 2023, 3M changed certain of its non-GAAP measures by adjusting for the results of manufactured PFAS products in arriving at results, adjusted for special items. In the fourth quarter of 2022, 3M recorded a charge for PFAS manufacturing exit costs and included it as an adjustment in arriving at results, adjusted for special items. The 2023 non-GAAP measure change involved expanding the extent of adjustment to include the sales and estimates of income (including exit costs) and associated activity regarding manufactured PFAS products that 3M plans to exit by the end of 2025. This change also impacts other non-GAAP measures such as adjusted free cash flow, adjusted free cash flow conversion and adjusted EBITDA to similarly include relevant special item adjustments for manufactured PFAS products. The information herein reflects the impacts of these changes for all periods presented.

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

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

SUPPLEMENTAL FINANCIAL INFORMATION

NON-GAAP MEASURES (CONTINUED)

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 Russia exit charges benefits, divestiture-related restructuring 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".
