FOR IMMEDIATE RELEASE

3M First-Quarter Sales Increase 25 Percent; Per-Share Earnings Rise 74 Percent

— Company Raises 2010 Sales and Earnings Expectations —

ST. PAUL, Minn. — April 27, 2010 - 3M (NYSE: MMM) today reported first-quarter earnings of $1.29 per share on sales of $6.3 billion. Operating income margins were 22.8 percent, up 7 percentage points year-on-year. Sales and per-share earnings increased 24.7 percent and 74.3 percent, respectively, versus the first quarter of 2009.

Each of the company’s six business segments posted double-digit sales growth and 20 percent-plus operating income margins. Sales growth was strongest in emerging economies, where sales expanded by 47 percent versus the first quarter of 2009. Free cash flow (c) more than doubled to $925 million, a first-quarter record for the company, and free cash flow conversion was 99 percent.

Included in first-quarter 2010 earnings was a one-time, non-cash income tax charge of $84 million, or 11 cents per share, resulting from Medicare Part D changes imbedded in the recently enacted Patient Protection and Affordable Care Act. Excluding this charge, first-quarter 2010 earnings were $1.40 per share, also a record for any first quarter in 3M’s history. First-quarter 2009 earnings included restructuring-related charges of $45 million after tax, or 7 cents per share.

“By any measure, we are off to a tremendous start in 2010,” said George W. Buckley, 3M chairman, president and chief executive officer. “First-quarter sales were boosted by improved market penetration and new product flow along with significant growth in important end-markets such as electronics, automotive OEM and respiratory protection products. I thank the many 3M business teams around the world for an outstanding first-quarter effort.”

Buckley continued, “This quarter’s results clearly demonstrate the benefits of our long-term strategy of accelerating investment in higher growth programs. In addition, we are successfully driving growth in adjacent market spaces, while continuing to maintain exceptional operating returns and free cash flow. These efforts, combined with an improving economic backdrop, make me even more confident in 3M’s future.”

For the second consecutive quarter, 3M increased its full-year 2010 performance expectations. The company now expects organic sales volumes to grow 10 to 12 percent versus a prior expected range of 5 to 7 percent. Operating income margins, previously anticipated to be in the range of 21 to 22 percent, are now expected to exceed 22 percent for the year. Finally, the company expects that per-share earnings will be in the range of $5.40 to $5.60, excluding the Medicare Part D-related charge, versus a prior expected range of $4.90 to $5.10.

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, 2010 and 2009.

Adjusted Non-GAAP measure	$	1,445	$	1,014	$	1.40	$	870	$	563	$	0.81

(a)		The first quarter of 2010 includes a one-time, non-cash income tax charge of $84 million, or 11 cents per diluted share, resulting from the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010 (collectively, the “Act”). The charge is due to a reduction in the value of the Company’s deferred tax asset as a result of the Act’s change to the tax treatment of Medicare Part D reimbursements.

(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. These charges included employee-related liabilities for severance and benefits of approximately $61 million and fixed asset impairments of approximately $6 million, with all business segments impacted by these actions. These charges were recorded in cost of sales ($17 million); selling, general and administrative expenses ($47 million); and research, development and related expenses ($3 million).

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, 2010 and 2009. As discussed in more detail later in the section entitled “Business Segments,” 3M made certain product moves between its business segments in the first quarter of 2010. Segment information for all periods presented has been reclassified to reflect these changes.

(c) 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.

BUSINESS SEGMENTS

(Unaudited)

Effective in the first quarter of 2010, 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 to business segments related to product moves for the Health Care segment, Consumer and Office segment, Display and Graphics segment, or Electro and Communications segment. In addition, 3M results in total did not change. The financial information presented herein reflects for all periods presented the impact of product moves between business segments, which are summarized as follows:

Certain acoustic systems products in the Occupational Health and Environmental Safety Division (part of the Safety, Security and Protection Services business segment) were transferred to the Automotive Division within the Industrial and Transportation business segment. In addition, thermal acoustics systems products which were included in the Occupational Health and Environmental Safety Division as a result of 3M’s April 2008 acquisition of Aearo Holding Corp. were transferred to the Aerospace and Aircraft Maintenance Department within the Industrial and Transportation business segment. These product moves establish an acoustic center of excellence within the Industrial and Transportation business segment. The preceding product moves resulted in an increase in net sales for total year 2009 of $116 million for Industrial and Transportation, which was offset by a corresponding decrease in net sales for Safety, Security and Protection Services.
