ST. PAUL, Minn. – Jan. 26, 2016 – 3M (NYSE: MMM) today reported its fourth-quarter and full-year 2015 results.

“The fourth quarter capped off a year of disciplined execution from our global team with solid margin and cash flow performance,” said Inge G. Thulin, 3M’s chairman, president and chief executive officer. “Throughout 2015 we controlled the controllable, while investing in the business and also returning significant cash to shareholders.

“2015 was an important year as we prepared and positioned our company for long-term success,” Thulin continued. “We strengthened and focused our portfolio, made significant investments in the business to support growth, and made good progress in moving toward a more efficient business model through business transformation and our corporate restructuring. We are building an even stronger and more competitive company for 2016 and beyond.”

Fourth-quarter GAAP earnings were $1.66 per share, a decrease of 8.3 percent versus the fourth quarter of 2014. Sales declined 5.4 percent year-on-year to $7.3 billion. Organic local-currency sales declined 1.1 percent while acquisitions, net of divestitures, added 1.5 percent to sales. Foreign currency translation reduced sales by 5.8 percent year-on-year.

During the fourth quarter the company incurred a pre-tax charge of $114 million ($88 million after-tax), or $0.14 per share, related to the corporate restructuring it announced in October. The restructuring was primarily focused on structural overhead, largely in the U.S., along with slower-growing markets with particular emphasis on EMEA (Europe, Middle East and Africa) and Latin America. Excluding restructuring, fourth-quarter earnings were $1.80 per share, a decrease of 0.6 percent versus the prior year.

Operating income was $1.5 billion and operating income margins for the quarter were 20.5 percent, down 1.0 percentage point year-on-year. Excluding restructuring, operating income was $1.6 billion in the quarter and operating margins were 22.1 percent, up 0.6 percentage points year-on-year.

Fourth-quarter net income was $1.0 billion and the company converted 182 percent of net income to free cash flow.

3M paid $628 million in cash dividends to shareholders and repurchased $1.1 billion of its own shares during the quarter.

Organic local-currency sales growth was 4.5 percent in Health Care and 2.7 percent in Consumer with declines of 1.8 percent in Industrial, 2.5 percent in Safety and Graphics, and 7.7 percent in Electronics and Energy. On a geographic basis, organic local-currency sales growth was 1.1 percent in EMEA with declines of 0.4 percent in the U.S., 0.6 percent in Latin America/Canada and 2.7 percent in Asia Pacific.

Full-year 2015 GAAP earnings were $7.58 per share, an increase of 1.2 percent, or up 3.1 percent excluding the fourth-quarter restructuring. Sales decreased 4.9 percent to $30.3 billion with organic local-currency growth of 1.3 percent. Acquisitions, net of divestitures, increased sales 0.6 percent. Foreign currency translation reduced sales by 6.8 percent.

Full-year operating income margins were 22.9 percent, up 50 basis points versus 2014, or up 90 basis points excluding the fourth-quarter restructuring. 3M converted 103 percent of net income to free cash flow for the year and generated 22.5 percent return on invested capital.

For the full year, 3M paid $2.6 billion in cash dividends to shareholders and repurchased $5.2 billion of its own shares.

3M affirmed its 2016 full-year performance expectations. The company expects 2016 earnings to be in the range of $8.10 to $8.45 per share with organic local-currency sales growth of 1 to 3 percent. 3M also expects free cash flow conversion to be in the range of 95 to 105 percent.

CONDENSED CONSOLIDATED BALANCE SHEET

(Dollars in millions)

(Unaudited)

(a)                                 In 2015, 3M updated its methodology related to how it classifies marketable securities between current and non-current. 3M also adopted two new accounting pronouncements that impacted the classification of deferred tax assets and deferred tax liabilities between current and non-current, along with how 3M accounts for issuance costs related to long-term debt. All periods presented have been updated to reflect these changes.

(b)                                 In August 2015, 3M completed the acquisitions of Capital Safety and Polypore’s Separations Media business. In March 2015, 3M completed the acquisition of Ivera Medical Corp. The combination of these acquisitions increased goodwill and intangible assets — net by approximately $4.0 billion at Dec. 31, 2015.

(c)                                  In December 2014, 3M’s board of directors declared a first-quarter 2015 dividend of $1.025 per share (paid in March 2015). This reduced 3M’s stockholders equity and increased other current liabilities as of Dec. 31, 2014, by approximately $0.6 billion.

(d)                                 This is primarily related to the purchase of the remaining noncontrolling interest of Sumitomo 3M Limited from Sumitomo Electric Industries, Ltd. for 90 billion Japanese Yen. The transaction closed on Sept. 1, 2014, for approximately $865 million at closing date exchange rates. Approximately $694 million was recorded as a financing activity in the statement of cash flows while the remainder was recorded as a current liability (paid in October 2014).

SUPPLEMENTAL FINANCIAL INFORMATION

NON-GAAP MEASURES

(Dollars in millions)

(Unaudited)

(e)                                  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 useful measures of performance and uses these measures as an indication of the strength of the company and its ability to generate cash.

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

(g)                                  The Company uses various working capital measures that place emphasis and focus on certain working capital assets and liabilities. 3M’s net working capital index is defined as quarterly net sales multiplied by four, divided by ending net accounts receivable plus inventory less accounts payable. This measure is not recognized under U.S. GAAP and may not be comparable to similarly titled measures used by other companies.

(h)                                 The Company uses non-GAAP measures to focus on shareholder value creation. 3M uses Return on Invested Capital (ROIC), defined as annualized after-tax operating income (including interest income) divided by average operating capital. Operating capital is defined as net assets (total assets less total liabilities) excluding debt. This measure is not recognized under U.S. GAAP and may not be comparable to similarly titled measures used by other companies.
