FOR IMMEDIATE RELEASE

3M First-Quarter Sales Rise 15 Percent to a Record $7.3 Billion;

Earnings Rise 16 Percent to $1.49 Per Share

– Company Raises 2011 Earnings Expectations —

ST. PAUL, Minn. — April 26, 2011 – 3M (NYSE: MMM) today reported record first-quarter sales of $7.3 billion, up 15.2 percent year-on-year, including an 8.9 percent increase in organic sales volumes. Earnings rose 15.5 percent to $1.49 per share and operating margins for the quarter were 21.6 percent. All six of the company’s business segments posted operating margins above 21 percent in the quarter.

The company estimates that combined direct and indirect business disruption resulting from events in Japan reduced first-quarter sales growth by 70 basis points, operating margins by 40 basis points and earnings by $0.03 per share.

Sales increased at a double-digit rate in all geographic regions, with Asia Pacific up 21.0 percent, Latin America/Canada up 19.5 percent, Europe up 13.1 percent and the United States up 10.2 percent. All six of 3M’s business segments expanded sales in the quarter, with particular strength in Electro and Communications at 20.5 percent, Industrial and Transportation at 20.3 percent and Safety, Security and Protection Services at 14.4 percent.

Sales in emerging markets grew by 24 percent in the first quarter and now comprise 34 percent of 3M’s worldwide sales. Sales grew by 30 percent in India, 27 percent in China/Hong Kong and 25 percent in Brazil.

“We are off to a tremendous start in 2011 with first-quarter organic sales growth of 9 percent — or 10.5 percent adjusting for Japan and H1N1 impacts,” said George W. Buckley, 3M chairman, president and chief executive officer. “New product flow is accelerating, boosted by higher investment in laboratory, sales and marketing and manufacturing capacity. Sales are growing faster as a result and our businesses are growing most everywhere in the world.” The company noted that its new product vitality index, which measures the percent of sales attributed to new products, is projected to rise again in 2011, on top of a record 31 percent in 2010.

“In addition, we were able to more than overcome the impact of the terrible earthquake in Japan and its tragic aftermath in the tsunami and nuclear power plant issues,” Buckley continued. “I would like to thank all our employees for their outstanding execution in the first quarter, with special heartfelt thanks to our courageous Japanese team for selflessly responding to this challenge. Our hearts go out to all of them and to their nation.”

3M estimates that combined direct and indirect business disruption resulting from events in Japan will reduce full year sales growth by approximately one percentage point, operating margins by 30 basis points and earnings by $0.10 to $0.13 per share.

Despite these headwinds, 3M increased its 2011 performance expectations. The company now expects full-year earnings will be in the range of $6.05 to $6.25 per share versus a prior expectation of $5.95 to $6.20 per share. Included in this estimate is a $0.22 per share year-on-year increase in pension

and postretirement benefit expense. Excluding the pension and postretirement expense increase, 2011 earnings would be in the range of $6.27 to $6.47 per share, an increase of 11 to 15 percent year-over-year. The company also updated its expectation for organic sales volume growth to a range of 6.0 to 7.5 percent versus a prior range of 5.5 to 7.5 percent. 3M expects that currency effects will add 2 to 3 percent to sales for the year and acquisitions will add another 4 to 6 percent.

Key Financial Highlights

First-quarter worldwide sales totaled $7.3 billion, up 15.2 percent compared to the first quarter of 2010. Organic volumes grew 8.9 percent, selling prices rose 0.1 percent, acquisitions added 3.2 percent and foreign exchange added 3.0 percent to sales in the quarter.

Local-currency sales including acquisitions grew in all six of the company’s business segments, with Electro and Communications up 17.1 percent, Industrial and Transportation up 16.9 percent, Safety, Security and Protection Services up 11.3 percent, Health Care up 9.7 percent, Consumer and Office up 7.0 percent and Display and Graphics up 6.4 percent.

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. There were no special items for the three-months ended March 31, 2011.

	Three-months ended March 31, 2010
	Operating income		Net income		Diluted earnings per share
Reported GAAP measure	$	1,445	$	930	$	1.29

Special items:
Medicare tax change (a)	—		84		0.11
Adjusted Non-GAAP measure	$	1,445	$	1,014	$	1.40

(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.

BUSINESS SEGMENTS

(Dollars in millions)

(Unaudited)

Effective in the first quarter of 2011, 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 impacting business segments related to product moves for the Display and Graphics segment or the Consumer and Office 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 pressure sensitive adhesives products within the Industrial Adhesives and Tapes Division and shock absorption and vibration dampening products used in electronics within the Aerospace and Aircraft Maintenance Department (both within the Industrial and Transportation business segment) were transferred to the Electronic Markets Materials Division (part of the Electro and Communications business segment). In addition, certain medical respirator products within the Infection Prevention Division (part of the Health Care business segment) were transferred to the Occupational Health and Environmental Safety Division (within the Safety, Security and Protection Services business segment). The preceding product moves resulted in decreases in net sales for the total year 2010 of $152 million in the Industrial and Transportation business segment and $8 million in the Health Care business segment. These decreases were offset by increases in net sales for the total year 2010 of $121 million for the Electro and Communications business segment and $8 million for the Safety, Security and Protection Services business segment along with a $31 million change in the elimination of dual credit sales and corporate and unallocated.
