3M CEO Introduces Priorities for the Future, Sets Five-Year Financial Targets

3M also releases full-year guidance for 2019

ST. PAUL, Minn. - (Nov. 15, 2018) - Speaking today at the company’s Investor Day in St. Paul, 3M CEO Mike Roman will lay out new five-year financial objectives while introducing his priorities for the future. The four priorities — focused around Portfolio, Innovation, Transformation, and People and Culture — are positioning 3M for long-term growth and value creation.

These priorities are a key component of the 3M value model, and Roman will detail how that unique model will drive performance today and into the future. He will discuss 3M’s plans to continue actively managing its portfolio to maximize value, and how the company’s transformation initiative will enable greater productivity and continued margin expansion. The company will also emphasize how 3M science and technologies are being applied to high-growth areas such as automotive electrification, advanced wound care, connected safety, biopharma filtration, and data centers.

“As we work to deliver a strong close to 2018, we are positioning our company for success in 2019 and beyond — which includes taking actions around our four priorities,” said Mike Roman, 3M chief executive officer. “Our team is focused on growth, operational execution, and delivering for our customers and shareholders.”

3M’s new five-year financial objectives — covering 2019 through 2023 — are:

·                  3 to 5 percent organic local currency sales growth

·                  8 to 11 percent growth in earnings per share

·                  20 percent return on invested capital

·                  100 percent free cash flow conversion

In addition to its five-year goals, 3M will also outline its expectations for 2019:

·                  1 to 3 percent total sales growth

·                  2 to 4 percent organic local currency sales growth

·                  Earnings per share of $10.60 to $11.05

·                  20 to 25 percent EPS growth, on a GAAP basis

·                  7 to 11 percent EPS growth, adjusting for certain 2018 items

·                  22 to 25 percent return on invested capital

·                  95 to 105 percent free cash flow conversion (based on operating cash flow of $7.9 to $8.5 billion).

Refer to section entitled “Supplemental Financial Information, Non-GAAP Measures” for more detail.

In 2019, 3M plans to invest $2 billion in research and development — or approximately 6 percent of sales — along with $1.7 to $2 billion in capital expenditures. The company also plans gross share repurchases in the range of $2 to $4 billion for the year.

(a)                                 In February 2018, 3M reached an agreement with the State of Minnesota that resolved the previously disclosed Natural Resource Damages (NRD) lawsuit filed by the State against the Company related to certain PFCs present in the environment. Under the terms of the settlement, 3M agreed to provide an $850 million grant to the State for a special “3M Water Quality and Sustainability Fund.” This Fund will enable projects that support water sustainability in the Twin Cities East Metro region, such as continued delivery of water to residents and enhancing groundwater recharge to support sustainable growth. The projects will also result in habitat and recreation improvements, such as fishing piers, trails, and open space preservation. 3M recorded a pre-tax charge of $897 million, inclusive of legal fees and other related obligations, in the first quarter of 2018 associated with the resolution of this matter. 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). 3M’s provisional accounting continues to be subject to adjustment during the measurement period of up to one year following the December 2017 enactment of TCJA. In the second quarter of 2018, 3M completed the sale of substantially all of its Communication Markets Division and reflected a pre-tax gain of $494 million as a result of this divestiture. During the second quarter of 2018, management approved and committed to undertake certain restructuring actions related to addressing corporate functional costs following the Communication Markets Division divestiture. These actions resulted in a second quarter 2018 pre-tax charge of $105 million.

In addition to providing full-year estimated 2018 financial results in accordance with U.S. GAAP, the Company also provides non-GAAP measures that adjust for the impacts of the NRD resolution, measurement period adjustment to the impact of enactment of the TCJA, and the impact of the Communication Markets Division divestiture gain, net of restructuring actions. These items represent significant charges/benefits that impacted the Company’s financial results. Income before taxes, provision for income taxes, net income, earnings per share, and the effective tax rate are all measures for which 3M provides the estimated 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 this item 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.

(b)                                 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.

(c)                                  Return on Invested Capital (ROIC) is not defined under U.S. generally accepted accounting principles. Therefore, ROIC 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 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.
