3M Delivers Second-Quarter Earnings of $1.60 per Share;

Sales Rise 14 Percent to a Record $7.7 Billion

ST. PAUL, Minn. — July 26, 2011 - 3M (NYSE: MMM) today reported record second-quarter sales of $7.7 billion, up 14.1 percent year-on-year. Earnings rose 3.9 percent to $1.60 per share and operating margins were 21.6 percent. The company generated $1.2 billion in free cash flow during the quarter, equal to 100 percent of net income.

Sales increased in all geographic regions, with Europe up 24.1 percent, Latin America/Canada up 20.2 percent, Asia Pacific up 11.0 percent and the U.S. up 8.7 percent. Five of the company’s six business segments expanded sales in the quarter, with particular strength in Industrial and Transportation at 24.6 percent and Safety, Security and Protection Services at 19.7 percent.

The company estimates that combined direct and indirect business disruption resulting from the March earthquake in Japan reduced second-quarter sales growth by 2.4 percentage points, operating margins by 50 basis points and earnings by $0.07 per share. Without these estimated impacts, second-quarter sales growth was 16.5 percent, operating margins were 22.1 percent and earnings per share growth was 8.4 percent. For the full year 2011, 3M estimates that the Japan earthquake impacts will reduce sales growth by approximately one percentage point, operating margins by 30 basis points and earnings by $0.11 to $0.12 per share.

On a worldwide basis, second-quarter organic sales volumes rose 3.2 percent (5.6 percent excluding Japan earthquake impacts) and selling prices increased 0.8 percent. Acquisitions added 4.0 percent and foreign exchange impacts added 6.1 percent to second-quarter sales growth.

“We posted record second-quarter sales and earnings per share and generated significant free cash flow in the quarter, and we did so in the face of some sizable headwinds,” said George W. Buckley, 3M chairman, president and chief executive officer. “Most significant was the impact of the Japan earthquake, which was in line with our projections. In addition, a larger-than-anticipated contraction in LCD TV end-market demand affected our sales, reflecting a tighter consumer electronics market as OEMs work to reduce channel inventories and lower their unit costs. Without these two impacts, organic sales growth would have been 8 percent, so underlying strength remains.”

Buckley continued, “3M’s innovation engine continues to accelerate, and we expect further growth in new products this year. While economic growth moderated a bit in the second quarter, we believe that the global economy will continue to expand and 3M is well-positioned to capitalize on that growth.”

3M refined its previous guidance and now expects that 2011 full-year earnings will be in the range of $6.10 to $6.25 per share versus a prior expectation of $6.05 to $6.25 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 $6.32 to $6.47 per share, an increase of 12 to 15 percent year-over-year. The company affirmed its

expectation for full-year organic sales volume growth in the range of 6.0 to 7.5 percent. 3M expects that currency effects will add 3.5 to 4.5 percent to sales for the year and acquisitions will add another 3 to 4 percent.

Key Financial Highlights

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 six-months ended June 30, 2010.  There were no special items for the three-months and six-months ended June 30, 2011, or for the three-months ended June 30, 2010.

(a)         The first six months of 2010 includes a one-time, non-cash income tax charge of $84 million, or 12 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.

These immaterial revisions increased cash used in financing activities and decreased cash used in investing activities by the amounts indicated above for the respective periods.

(c)          Free cash flow is not defined under U.S. GAAP. Therefore, it should not be considered a substitute for income or cash flow data prepared in accordance with 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.

(d)         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.

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.
