Full-Year 2021 Outlook

3M’s full-year 2021 guidance remains unchanged with earnings expected to be in the range of $9.20 to $9.70 per share. The company expects its full-year total sales growth in the range of 5 to 8 percent with organic local-currency growth between 3 to 6 percent. 3M also expects its full-year free cash flow conversion to be in the range of 95 to 105 percent, as referenced in the “Supplemental Financial Information Non-GAAP Measures” section.

Committed to Leadership in Sustainability

In February, 3M announced plans to invest approximately $1 billion over the next 20 years to accelerate its new environmental goals: achieve carbon neutrality by 2050, reduce water use by 25% at its facilities, and return higher quality water to the environment after use in manufacturing operations.

Achieving Carbon Neutrality

•

By applying science and technological expertise, 3M expects to further reduce carbon emissions 50% by 2030, 80% by 2040, and achieve 100% carbon neutrality in its operations by 2050.^1,2

Reducing Water Use

•

3M is targeting water use reductions of 10% by 2022, 20% by 2025, and 25% by 2030.^1,3 Through various efforts, 3M expects to reduce its overall water usage by 2.5 billion gallons per year. The new commitments build upon the company's existing 2025 goal of engaging with all of the water-stressed/scarce communities where it manufactures on community-wide approaches to water management.

Returning Higher Quality Water

•

3M expects to install state-of-the-art water purification technology by the end of 2023 and be fully operational in 2024 at all of its largest water-using locations. This will enable the company to return even higher quality water to the environment after its use in manufacturing operations. The company will use its expertise and advanced technology to remove impurities from the water it uses.

In addition, 3M announced last week it expects to reduce its dependence on virgin fossil-based plastics by 125 million pounds by 2025.⁴To achieve this new goal, 3M is innovating the products and packaging in its Consumer Business Group with advancements focused on the use of recycled content and bio-based plastics, as well as more sustainable product and packaging designs to decrease overall plastic use.⁴

Over the last two decades 3M has reduced its emissions by 70 percent, while doubling its revenues. The company’s headquarters in Saint Paul, Minnesota, is powered by renewable electricity, and 40 percent of 3M’s global electricity use is renewable, on its way to 100 percent. Sustainability is embedded in every new 3M product, and over the last five years the company’s innovations have helped customers avoid 75 million tons of emissions. The company will provide its annual sustainability report in early May which will provide further details.

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.

Net Debt (non-GAAP measure)	2021		2020
Total debt	$	18,187	$	18,795
Less: Cash, cash equivalents and marketable securities		5,168		5,068
Net debt ^(e)	$	13,019	$	13,727

(e)

Net debt is not defined under U.S. GAAP and may not be computed the same as similarly titled measures used by other companies. The Company defines net debt as total debt less the total of cash, cash equivalents and current and long-term marketable securities. 3M believes net debt is meaningful to investors as 3M considers net debt and its components to be an important indicator of liquidity and a guiding measure of capital structure strategy.

SUPPLEMENTAL FINANCIAL INFORMATION

NON-GAAP MEASURES – (CONTINUED)

(Unaudited)

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:

Significant litigation-related charges/benefits:

•

In the first quarter of 2020, 3M recorded a net pre-tax charge of $17 million ($13 million after tax) related to PFAS (certain perfluorinated compounds)matters. The charge was more than offset by a reduction in tax expense of $52 million related to resolution of tax treatment with authorities regarding the previously disclosed 2018 agreement reached with the State of Minnesota that resolved the Natural Resources Damages lawsuit. These items, in aggregate, resulted in a $39 million after-tax benefit. In the first quarter of 2021 and 2020, 3M made payments of approximately $4 million and $63 million, respectively, related to significant litigation-related matters.

Gain/loss on sale of businesses:

•

In the first quarter of 2020, 3M recorded a pre-tax gain of $2 million ($1 million loss after tax) related to the sale of its advanced ballistic-protection business and recognition of certain contingent consideration.

Divestiture-related restructuring actions:

•

In the first quarter of 2021, 3M made payments of approximately $1 million associated with divestiture-related restructuring actions.

Enactment/measurement period adjustments related to the Tax Cuts and Jobs Act (TCJA)

•

In the first quarter of 2021, 3M made payments of approximately $9 million related to the transition tax expense incurred as a result of the 2017 enactment of the TCJA.

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.

BUSINESS SEGMENTS

(Unaudited)

3M discloses business segment operating income as its measure of segment profit/loss, reconciled to both total 3M operating income and income before taxes. Note 19 to 3M’s consolidated financial statements in its 2020 Annual Report on Form 10-K describes 3M’s business segments and measure of segment operating performance used by 3M’s chief operating decision maker (CODM). As discussed therein, the measure of segment operating performance includes dual credit for certain related operating income and excludes certain expenses and income that are not allocated to business segments and instead reflected in Corporate and Unallocated.

Additionally, the following special items are excluded from business segment operating income and, instead, are included within Corporate and Unallocated: significant litigation-related charges/benefits, gain/loss on sale of businesses, and divestiture-related restructuring actions.

Effective in the first quarter of 2021, 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) was updated. The change to business segment operating income aligns with the update to how the CODM assesses performance and allocates resources for the Company’s business segments. The change included the following:

Changes in cost attribution

The extent of allocation and method of attribution of certain net costs were updated to result in fewer items remaining in Corporate and Unallocated and, instead, including them in 3M’s business segments’ operating performance. Previously, a larger portion of ongoing corporate staff costs and costs associated with centrally managed material resource centers was retained in Corporate and Unallocated. In addition, portions of pension costs and costs associated with certain centrally managed but ongoing business-related legal matters, along with certain insurance-related costs, were retained in Corporate and Unallocated.

Continued alignment of customer account activity

As part of 3M’s regular customer-focus initiatives, the Company realigned certain customer account activity (“sales district”) to correlate with the primary divisional product offerings in various countries and reduce complexity for customers when interacting with multiple 3M businesses. This impacted the amount of dual credit certain business segments receive as a result of sales district attribution.

Also effective in the first quarter of 2021, within 3M’s Consumer business segment, certain safety products formerly within the Construction and Home Improvement Division and the Stationery and Office Division were moved to the newly-named Consumer Health and Safety Division (formerly the Consumer Health Care Division).

The financial information presented herein reflects the impact of the preceding changes for all periods presented.
