NON-GAAP MEASURES

(Dollars in millions)

(Unaudited)

(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.

BUSINESS SEGMENTS

(Dollars in millions)

(Unaudited)

Effective in the first quarter of 2016, 3M made a product line reporting change involving two of its business segments in its continuing effort to improve the alignment of its businesses around markets and customers.

The change between business segments was as follows:

·                  Elements of the electronic bonding product lines were previously separately reflected in the Electronics Materials Solutions Division (Electronics and Energy business segment) and the Industrial Adhesives and Tapes Division (Industrial business segment). Effective in the first quarter of 2016, certain sales and operating income results for these electronic bonding product lines in aggregate were equally divided between the Electronics and Energy business segment and Industrial business segment. This change resulted in a decrease in net sales and operating income for total year 2015 of $33 million and $7 million, respectively, in the Industrial business segment offset by a corresponding increase in the Electronics and Energy business segment.

The financial information presented herein reflects the impact of the preceding product line reporting change between business segments for all periods presented. Refer to 3M’s Current Report on Form 8-K furnished on March 15, 2016, for additional supplemental unaudited historical business segment net sales and operating income information. In addition, these business segment changes were reflected in 3M’s Current Report on Form 8-K dated May 17, 2016, (which updated 3M’s 2015 Annual Report on Form 10-K) and 3M’s Quarterly Report on Form 10-Q for the period ended March 31, 2016.
