ST. PAUL, Minn. — Apr. 25, 2019 - 3M (NYSE: MMM) today reported first-quarter 2019 results.

“The first quarter was a disappointing start to the year for 3M,” said Mike Roman, 3M chief executive officer. “We continued to face slowing conditions in key end markets which impacted both organic growth and margins, and our operational execution also fell short of the expectations we have for ourselves. As a result, we have stepped up additional actions — including restructuring — to drive productivity, reduce costs, and increase cash flow as we manage through challenges in some of our end markets.

“While we take actions to manage through the near-term, we also continue to invest in growth to position 3M for the future,” Roman continued. “We recently implemented a significant portfolio realignment from five to four business groups, which will enable us to better serve our customers and global markets. Moving forward, I am confident that we are making the necessary changes and focused on the right priorities to accelerate 3M into a stronger future.”

First-Quarter Results

Sales were down 5.0 percent to $7.9 billion. Organic local-currency sales declined 1.1 percent while divestitures, net of acquisitions, decreased sales by 0.5 percent. Foreign currency translation decreased sales by 3.4 percent year-on-year.

Total sales grew 0.3 percent in Health Care, with declines of 1.9 percent in Consumer, 4.2 percent in Safety and Graphics, 6.6 percent in Industrial, and 11.8 percent in Electronics and Energy. Organic local-currency sales increased 0.9 percent in Consumer and 0.7 percent in Health Care, with decreases of 0.1 percent in Safety and Graphics, 2.8 percent in Industrial, and 3.0 percent in Electronics and Energy.

On a geographic basis, total sales grew 0.1 percent in the U.S., with declines of 6.5 percent in Latin America/Canada, 7.4 percent in Asia Pacific, and 9.4 percent in EMEA (Europe, Middle East and Africa). Organic local-currency sales increased 0.8 percent in Latin America/Canada and 0.7 percent in EMEA, with decreases of 0.4 percent in the U.S. and 3.6 percent in Asia Pacific.

First-quarter 2019 GAAP earnings were $1.51 per share, an increase of 54.1 percent versus the first quarter of 2018. During the first quarter of 2019, the company recorded significant litigation-related pre-tax charges of $548 million, or $0.72 per share, as referenced in the “Significant Litigation-Related Update” section below. First-quarter 2018 GAAP earnings were $0.98 per share which included a $0.36 per share impact for an expense related to the enactment of the Tax Cuts and Jobs Act (TCJA) and a $1.16 per share impact for significant litigation-related charges.

Excluding the above items, first-quarter 2019 adjusted earnings were $2.23 per share versus $2.50 per share in the first-quarter 2018, as referenced in the “Supplemental Financial Information Non-GAAP Measures” section.

First-quarter operating income was $1.1 billion with operating margins of 14.4 percent. Excluding significant litigation-related charges, operating income was $1.7 billion with operating margins of 21.4 percent.

The company’s operating cash flow was $1.0 billion, contributing to conversion of 74 percent of net income to free cash flow, as referenced in the “Supplemental Financial Information Non-GAAP Measures” section.

3M paid $830 million in cash dividends to shareholders and repurchased $701 million of its own shares during the quarter.

Significant Litigation-Related Update

Two significant litigation issues impacted 3M’s first-quarter results. The company established a reserve of $235 million to resolve certain environmental matters and litigation, in which 3M is a defendant, related to its historical manufacture and disposal of PFAS-containing waste. 3M manufactured or used PFAS at five manufacturing plants globally, including in Alabama, Illinois and Minnesota in the United States, as well as in Belgium and Germany. The company also increased its respirator reserve by $313 million to address the cost of resolving all current and expected future coal mine dust lawsuits in Kentucky and West Virginia. These actions resulted in a total significant litigation-related pre-tax charge of $548 million. 3M’s upcoming Form 10-Q filing will include additional details.

(a)Free cash flow and free cash flow conversion are not defined under U.S. generally accepted accounting principles (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 free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. The Company defines free cash flow conversion as free cash flow divided by net income attributable to 3M. The Company believes free cash flow and free cash flow conversion are meaningful to investors as they function as 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.

(b)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.

The Company defines ROIC as adjusted net income (net income including non-controlling interest plus after-tax interest expense) divided by average invested capital (equity plus debt). The Company believes ROIC is meaningful to investors as it focuses on shareholder value creation.

(d)In the first quarter of 2019, the Company recorded significant litigation-related charges of $548 million ($424 million after tax) related to historical PFAS (certain perfluorinated compounds) manufacturing operations and coal mine dust respirator mask lawsuits. In the first quarter of 2018, the Company recorded significant litigation-related charges of $897 million ($710 million after tax) from the previously disclosed agreement reached with the State of Minnesota that resolved the Natural Resource Damages (NRD) lawsuit. Also during the first quarter of 2018, 3M recorded a tax expense of $217 million related to a measurement period adjustment to the provisional amounts recorded in December 2017 from the enactment of the Tax Cuts and Jobs Act (TCJA).

In addition to providing financial results in accordance with U.S. GAAP, the Company also provides non-GAAP measures that adjust for the impacts of significant litigation-related charges and enactment/measurement period adjustments to the impact of the enactment of the TCJA. These items represent significant charges/benefits that impacted the Company’s financial results. Operating income, operating income margin, effective tax rate, net income, and earnings per share are all measures for which 3M provides the GAAP measure and an adjusted measure. 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 the Company’s operations. The Company believes that discussion of results adjusted for these items is meaningful to investors as it provides a useful analysis of ongoing underlying operating trends. The determination of these items may not be comparable to similarly titled measures used by other companies.

·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 largely impacted the amount of dual credit certain business segments receive as a result of sales district attribution. 3M business segment reporting measures include dual credit to business segments for certain sales and operating income. This dual credit is based on which business segment provides customer account activity with respect to a particular product sold in a specific country.

Creation of Closure and Masking Systems Division and Medical Solutions Division

·3M created the Closure and Masking Systems Division, which combines the masking tape, packaging tape and personal care portfolios formerly within Industrial Adhesives and Tapes Division in the Industrial business segment into a separate division also within the Industrial business segment. 3M created the Medical Solutions Division in the Health Care business segment, which combines the former Critical and Chronic Care Division and Infection Prevention Division (which were also both within the Health Care business segment).

Additional actions impacting business segment reporting

·The business associated with certain safety products sold through retail channels in the Asia Pacific region was realigned from the Personal Safety Division within the Safety and Graphics Business segment to the Construction and Home Improvement Division within the Consumer Business segment. Additionally, certain previously non-allocated costs related to manufacturing and technology of centrally managed material resource centers of expertise within Corporate and Unallocated are now reflected as being allocated to the business segments.

The financial information presented herein reflects the impact of the preceding changes for all periods presented. Refer to 3M’s Current Report on Form 8-K furnished on March 8, 2019, for additional supplemental unaudited historical business segment net sales and operating income information.
