**Item 2.02. Results of Operations and Financial Condition**

This Current Report on Form 8-K is being furnished to include supplemental unaudited historical information (furnished hereunder as Exhibit 99 and incorporated herein by reference) that was updated as a result of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in the measure of segment operating performance used by 3M's chief operating decision maker impacting 3M's segment reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes to non-GAAP measures - certain amounts adjusted for special items, adjusted free cash flow, adjusted free cash flow conversion, and adjusted EBITDA. The information reflects expanding the extent of special item adjustments to include the sales and estimates of income (including exit costs) and associated activity regarding manufactured PFAS products.

The Company did not operate using the new measure of segment operating performance until the first quarter of 2023 and will begin to report comparative results under this basis with the filing of its Quarterly Report on Form 10-Q for the quarter ending March 31, 2023. Until 3M's interim financial statements as of and for the quarter ending March 31, 2023 are issued, amounts on the updated basis are not in accordance with U.S. GAAP and, as a result, are considered non-GAAP measures.

The Company is furnishing this information as it believes it is useful to investors to aid in understanding, on a timely basis, the impacts of these changes on historical periods as they prepare to consider 3M's future results on the updated basis.

As used herein, the term "3M" or "Company" includes 3M Company and its subsidiaries unless the context indicates otherwise. The information contained in this Current Report shall not be deemed to be "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934 (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into a filing under the Securities Act of 1933, or the Exchange Act.

**Forward-Looking Statements**

This Current Report on Form 8-K contains forward-looking information about 3M's financial results and estimates and business prospects that involve substantial risks and uncertainties that could cause actual results to differ materially. Forward-looking statements relate to future events and typically address the Company's expected future business and financial performance.

**EXHIBIT 99**

This Current Report on Form 8-K is being furnished to include supplemental unaudited historical information that was updated as a result of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in the measure of segment operating performance used by 3M's chief operating decision maker impacting 3M's segment reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes to non-GAAP measures - certain amounts adjusted for special items, adjusted free cash flow, adjusted free cash flow conversion, and adjusted EBITDA. The information reflects expanding the extent of special item adjustments to include the sales and estimates of income (including exit costs) and associated activity regarding manufactured PFAS products.

The Company did not operate using the new measure of segment operating performance until the first quarter of 2023 and will begin to report comparative results under this basis with the filing of its Quarterly Report on Form 10-Q for the quarter ending March 31, 2023. Until 3M's interim financial statements as of and for the quarter ending March 31, 2023 are issued, amounts on the updated basis are not in accordance with U.S. GAAP and, as a result, are considered non-GAAP measures.

The Company is furnishing this information as it believes it is useful to investors to aid in understanding, on a timely basis, the impacts of these changes on historical periods as they prepare to consider 3M's future results on the updated basis.

As used herein, the term "3M" or "Company" includes 3M Company and its subsidiaries unless the context indicates otherwise. The information contained in this Current Report shall not be deemed to be "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934 (the "Exchange Act") or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into a filing under the Securities Act of 1933, or the Exchange Act.

***<u>Changes in the measure of segment operating performance used by 3M's chief operating decision maker (CODM)</u>*** 

Note 19 to 3M's consolidated financial statements in its 2022 Annual Report on Form 10-K describes 3M's business segments and measure of segment operating performance used by 3M's CODM.

Effective in the first quarter of 2023, the measure of segment operating performance used by 3M's CODM changed and, as a result, 3M's disclosed measure of segment profit/loss (business segment operating income) will be updated for all comparative periods presented. The change to business segment sales and operating income aligns with the update to how the CODM assesses performance and allocates resources for the Company's business segments. The changes included the following:

*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. In aggregate, for example relative to 2022, this change included ascribing approximately $135 million of gains previously included in the various business segments to Corporate and Unallocated as further reflected in the tables that follow.

*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 re-aligned from four divisions to the following three divisions: Home, Health and Auto Care; Construction and Home Improvement Markets; and Stationery and Office.

The tables below provide additional information with respect to the expected impact of the changes described above on previously reported segment and disaggregated revenue information. 3M discloses business segment operating income as its measure of segment profit/loss, reconciled to both total 3M operating income and income before taxes.

***<u>Changes to Non-GAAP Measures - Certain Amounts Adjusted for Special Items, Adjusted Free Cash Flow, Adjusted Free Cash Flow Conversion, and Adjusted EBITDA</u>***

In 2023, 3M is changing 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 record 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 involves 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 discussion and tables below include information with respect to historical amounts adjusted for special items (non-GAAP measures) reflective of the changes in measure of segment operating performance and non-GAAP measures described above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) &nbsp;&nbsp;&nbsp;&nbsp;In addition to reporting financial results in accordance with U.S. GAAP, 3M also provides non-GAAP measures that 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". Net sales (and sales change), operating income, segment operating income, operating income margin, income before taxes, provision for income taxes, effective tax rate, net income, and earnings per share are all measures for which 3M provides the reported GAAP measure and a measure adjusted for special items. The adjusted measures are not in accordance with, nor are they a substitute for, GAAP measures. The Company considers these non-GAAP measures in evaluating and managing its operations. The Company believes that discussion of results adjusted for special items is useful to investors in understanding underlying business performance, while also providing additional transparency to the special items. The determination of these items may not be comparable to similarly titled measures used by other companies.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) &nbsp;&nbsp;&nbsp;&nbsp;Total 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) &nbsp;&nbsp;&nbsp;&nbsp;Adjusted net cash provided by (used in) operating activities, adjusted free cash flow and adjusted free cash flow conversion are not defined under U.S. GAAP. Therefore, they should not be considered a substitute for income or cash flow data prepared in accordance with U.S. GAAP and may not be comparable to similarly titled measures used by other companies. The Company defines adjusted net cash provided by (used in) operating activities as net cash provided by operating activities, adjusted for special items. The Company defines adjusted free cash flow as adjusted net cash provided by (used in) operating activities less purchases of property, plant and equipment (PPE) adjusted for the estimated impact of such purchases associated with manufactured PFAS products activity. Cash payments associated with special items in the determination of adjusted net cash provided by (used in) operating activities are reflected net of applicable tax using the U.S. statutory corporate tax rate during the period of payment. It should not be inferred that the entire adjusted free cash flow amount is available for discretionary expenditures. The Company defines adjusted free cash flow conversion as adjusted free cash flow divided by net income attributable to 3M, adjusted for special items. Special items for the periods presented include the items described in the section entitled "Description of Special Items". The Company believes adjusted net cash provided by (used in) operating activities, adjusted free cash flow and adjusted free cash flow conversion all are meaningful to investors as they are useful measures of performance and the Company uses these measures as an indication of the strength of the Company and its ability to generate cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) &nbsp;&nbsp;&nbsp;&nbsp;Adjusted EBITDA and adjusted EBITDA margin are not defined under U.S. GAAP. Therefore, adjusted EBITDA and adjusted EBITDA margin should not be considered a substitute for other measures prepared in accordance with U.S. GAAP and may not be comparable to similarly titled measures used by other companies. The Company defines adjusted EBITDA as net income attributable to 3M, adjusted for net income/(loss) attributable to noncontrolling interest, (income)/loss from unconsolidated subsidiaries, provision for income taxes, other expense/(income), depreciation and amortization expense, and special items. The Company defines adjusted EBITDA margin as adjusted EBITDA divided by net sales, adjusted for special items. Special items for the periods presented include the items described in the section entitled "Description of Special Items". The Company considers these non-GAAP measures in evaluating and managing the Company's operations. The Company believes adjusted EBITDA and adjusted EBITDA margin are meaningful to investors as they provide useful analyses of ongoing underlying operating trends.

***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. These items align with those included in the section "Supplemental Financial Information — Non-GAAP Measures, Description of Special Items" within the Form 8-K dated January 24, 2023 which is largely repeated below, with the exception of the expansion of the extent of adjustment relative to PFAS manufactured products 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.

*Net costs for significant litigation:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• These relate to 3M's respirator mask/asbestos, PFAS-related other environmental, and Combat Arms Earplugs matters. Net costs include the impacts of changes in accrued liabilities, external legal fees, and insurance recoveries, along with the associated tax impacts. Prior to initiating voluntary chapter 11 bankruptcy proceedings in July 2022, net costs related to Combat Arms Earplugs and Aearo-respirator mask/asbestos matters along with non-Aearo respirator mask/asbestos matters were reflected as special items in the Safety and Industrial business segment. During the bankruptcy period, net costs related to Combat Arms Earplugs and Aearo-respirator mask/asbestos matters are reflected as corporate special items in Corporate and Unallocated. In 2022, 3M made payments of approximately $907 million related to net costs for significant litigation.

*Divestiture costs:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• These include costs related to separating and divesting substantially an entire business segment of 3M following public announcement of its intended divestiture.
