FOR IMMEDIATE RELEASE

3M Reports First-Quarter Results

- Company Updates Sales and Earnings Outlook -

ST. PAUL, Minn. — April 24, 2009 - 3M (NYSE: MMM) today announced first-quarter sales of $5.1 billion, a decrease of 21.3 percent from the first quarter of 2008. Net income was $518 million, or $0.74 per share, versus $1.0 billion, or $1.38 per share in the corresponding period last year (a). Excluding special items in 2009 (b), per share earnings were $0.81, down 41 percent year-on-year.

“As expected, the global economic slowdown dramatically affected our businesses in the first quarter,” said George W. Buckley, 3M chairman, president and CEO. “Substantial end-market declines and continued inventory takedowns in major industries, including automotive, consumer electronics and general industrial manufacturing, resulted in significantly lower sales and profits. Accordingly, we aggressively reduced our cost structure, lowered manufacturing output and intensified our attention to operational improvement. The combination of these actions drove strong operating income margins of more than 17 percent.”

Buckley continued, “In these extraordinary times, 3M employees around the world are energized by the challenges, remain keenly focused on our customers and are steadfastly committed to building for the future. In 2009, we will enhance our balance sheet by improving our free cash flow while still maintaining a significant investment in R&D. Our strategy will strengthen the company and position us for even greater success when global economies recover.”

The company adjusted its 2009 sales and earnings expectations to reflect ongoing global economic uncertainty. 3M now expects 2009 organic sales volume to decline between 11 percent and 15 percent, versus a previous planning assumption of negative 5 percent to negative 9 percent. The company also expects 2009 full-year earnings to be in the range of $3.90 to $4.30 per share, down from a previous range of $4.30 to $4.70. All estimates quoted exclude special items.

Key Financial Highlights

First-quarter worldwide sales totaled $5.1 billion, a decrease of 21.3 percent versus last year. Local-currency sales including acquisitions decreased 13.9 percent, and foreign exchange impacts reduced sales by an additional 7.1 points in the quarter.

SUPPLEMENTAL CONSOLIDATED STATEMENT OF INCOME INFORMATION

RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

(Millions, except per-share amounts)

(Unaudited)

In addition to reporting financial results in accordance with U.S. generally accepted accounting principles (GAAP), the company also discusses non-GAAP measures that exclude special items. Operating income, net income attributable to 3M (hereafter referred to as “net income”), and diluted earnings per share attributable to 3M common shareholders (hereafter referred to as “diluted earnings per share”) are all measures for which 3M provides the reported GAAP measure and an adjusted measure (excluding special items). Special items are not in accordance with, nor are they a substitute for, GAAP measures. Special items represent significant charges or credits that are important to an understanding of the company’s ongoing operations. The company uses these non-GAAP measures to evaluate and manage the company’s operations. The company believes that discussion of results excluding special items provides a useful analysis of ongoing operating trends. The determination of special items may not be comparable to similarly titled measures used by other companies.

The reconciliation provided below reconciles the non-GAAP financial measures with the most directly comparable GAAP financial measures for the three months ended March 31, 2009.

(b) During the first quarter of 2009, management approved and committed to undertake certain restructuring actions, which resulted in a pre-tax charge of $67 million. This charge related to employee-related liabilities for severance and benefits of approximately $61 million and fixed asset impairments of approximately $6 million. All business segments were impacted by these actions.

The reconciliation provided below reconciles the non-GAAP operating income measure by business segment with the most directly comparable GAAP financial measure for the three-months ended March 31, 2009. As discussed in more detail later in the section entitled “Business Segments,” 3M made certain changes to its business segments in the first quarter of 2009. Segment information for all periods presented has been reclassified to reflect these changes.

(e) Free cash flow is not defined under U.S. generally accepted accounting principles (GAAP). Therefore, it 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 believes free cash flow is a useful measure of performance and uses this measure as an indication of the strength of the company and its ability to generate cash.

(f) 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. generally accepted accounting principles and may not be comparable to similarly titled measures used by other companies.

BUSINESS SEGMENTS

(Dollars in millions)

(Unaudited)

Effective in the first quarter of 2009, 3M made certain product moves between its business segments in its continuing effort to drive growth by aligning businesses around markets and customers. There were no changes related to product moves for the Health Care segment, Display and Graphics segment or Electro and Communications segment, or 3M in total. The product moves between business segments are summarized as follows:

· Certain 3M window films, such as 3M™ Scotchtint™ Window Film for buildings and 3M™ Ultra Safety and Security Window Film for property and personal protection during destructive weather conditions, were previously part of the Building and Commercial Services Division within the Safety, Security and Protection Services business segment. These window films were transferred to the newly created Renewable Energy Division, which is part of the Industrial and Transportation business segment. The Renewable Energy Division consists of current 3M solar energy creation and management products and solutions, as well as products focused on the renewable energy markets. Renewable Energy’s portfolio includes various 3M products for solar energy production and solar energy management (such as window films) and also includes responsibility for wind, geothermal and biofuel oriented products. The preceding product moves resulted in an increase in net sales for total year 2008 of $152 million for Industrial and Transportation, which was offset by a corresponding decrease in net sales for Safety, Security and Protection Services.

· 3M acquired Aearo Holding Corp., the parent company of Aearo Technologies Inc. (hereafter referred to as Aearo), in April 2008. Aearo manufactures and sells personal protection and energy absorbing products through both the Industrial and Consumer retail channels. The consumer retail portion of Aearo’s business manufactures and markets personal safety products, including safety glasses and hearing protectors, among other products, to the do-it-yourself consumer retail markets. The do-it-yourself retail market portion of 3M’s Aearo business (previously in the Occupational Health and Environmental Safety Division within the Safety, Security and Protection Services business segment) was transferred to the Construction and Home Improvement Division within the Consumer and Office business segment. The preceding product moves resulted in an increase in net sales for total year 2008 of $49 million for Consumer and Office, which was offset by a corresponding decrease in net sales for Safety, Security and Protection Services.

Also, during the first quarter of 2009, 3M changed its segment reporting measures to include dual credit to business segments for certain U.S. sales and related operating income. Management now evaluates each of its six operating business segments based on net sales and operating income performance, including dual credit U.S. reporting. This change was made to further incentivize U.S. sales growth. As a result, 3M now provides additional (“dual”) credit to those business segments selling products in the U.S. to an external customer when that segment is not the primary seller of the product. For example, certain respirators are primarily sold by the Occupational Health and Environmental Safety Division within the Safety, Security and Protection Services business segment; however, the Industrial and Transportation business segment also sells this product to certain customers in its U.S. markets. In this example, the non-primary selling segment (Industrial

and Transportation) would also receive credit for the associated net sales it initiated and the related approximate operating income. The assigned operating income related to dual credit activity may differ from operating income that would result from actual costs associated with such sales. The offset to the dual credit business segment reporting is reflected as a reconciling item entitled “Elimination of Dual Credit,” such that sales and operating income for the U.S. in total are unchanged. Segment information for all periods presented has been reclassified to reflect this new segment structure.
