3M Reports Record First-Quarter Sales and Earnings;
Company Again Raises Guidance for 2004

ST. PAUL, Minn. — April 19, 2004 — 3M (NYSE: MMM) today announced its sales and earnings results for first quarter 2004.

The company reported net income of $722 million, or $0.90 per share, versus $502 million, or $0.63 per share, in the first quarter of 2003. Excluding special items (a) in the first quarter of 2003, net income increased 29 percent from $560 million last year, and earnings per share increased nearly 27 percent from $0.71 per share in last year’s first quarter.

“The 3M team again delivered outstanding results in the first quarter,” said W. James McNerney, Jr., 3M chairman and CEO. “Worldwide sales in local currencies increased in all seven of our businesses, and we generated double-digit increases in operating income and earnings per share. We are off to a great start in 2004.”

Worldwide sales in the first quarter totaled $4.94 billion, 14.4 percent higher than in the year-earlier quarter, driven by an 8.7 percent increase in sales volume. Currency effects increased sales by 6.1 percent while selling prices declined 0.4 percent. Local-currency sales (which excludes the impact of currency translation on sales) increased 20.4 percent in Display and Graphics, 9.2 percent in Safety, Security and Protection Services, 8.5 percent in Industrial, 8.1 percent in Transportation, 7.4 percent in Consumer and Office, 2.5 percent in Electro and Communications and 2.2 percent in Health Care.

Sales outside the United States totaled $3.06 billion, an increase of 21.6 percent versus last year’s comparable quarter. Volumes increased 11.9 percent, while selling prices declined 0.8 percent. Changes in the value of the U.S. dollar increased international sales by 10.5 percent. Local-currency sales increased 22.4 percent in Asia Pacific, 11.5 percent in the combined Latin America, Africa and Canada region and 1.2 percent in Europe.

In the United States, sales totaled $1.88 billion, up 4.2 percent from the same quarter of 2003. Volumes increased 4.0 percent, while selling prices improved by 0.2 percent.

“While the strength of the global economic recovery remains uneven and uncertain,” McNerney said, “we continue to work at improving all of our businesses. The combination of a strong and deep leadership team, a broad and diverse business portfolio, continued commitment to sustained operational excellence, and an improving organic growth engine positions us well to deliver sustainable increases in sales, earnings and cash flow.”

3M also increased its earnings outlook for 2004. For the year, the company now expects reported earnings will be within a range of $3.60 to $3.70 per share, versus a previous expectation of $3.52 to $3.62 per share. Second-quarter earnings are expected to be in the range of $0.94 to $0.96 per share.




Patrick D. Campbell, senior vice president and chief financial officer, will conduct an investor teleconference at 9 a.m. Eastern Time (8 a.m. Central) today. Investors can access a webcast of this conference, along with related charts and materials, at http://investor.3M.com.

(a) In addition to disclosing results that are determined in accordance with U.S. generally accepted accounting principles (GAAP), the company also discloses non-GAAP results that exclude special items. Special items represent significant charges or credits that are important to an understanding of the company’s ongoing operations. The company provides reconciliations of its non-GAAP financial reporting to the most comparable GAAP reporting. The company believes that discussion of results excluding special items provides a useful analysis of ongoing operating trends. Earnings per share and other amounts before special items are not measures recognized under GAAP. The determination of special items may not be comparable to similarly titled measures used by other companies. During the first quarter of 2003, 3M recorded pretax charges of $93 million ($58 million after-tax) related to an adverse court ruling in a lawsuit filed against 3M in 1997 by LePage’s Inc.

*Free cash flow is not defined under GAAP. Therefore, it is considered a non-GAAP measure. Non-GAAP measures 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.

**The company also uses non-GAAP 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, fourth quarter at year-end, 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.
