FOR IMMEDIATE RELEASE

3M Reports Net Income of $988 Million; Sales Increase 9 Percent to $6.5 Billion

- Company Reaffirms 2008 EPS Growth of Greater Than 10 Percent -

ST. PAUL, Minn. — April 24, 2008 - 3M (NYSE: MMM) today announced first-quarter sales of $6.5 billion, an increase of 8.9 percent over last year. Net income was $988 million, or $1.38 per share, versus $1.4 billion, or $1.85 per share in the first quarter of 2007. Included in first quarter 2007 results are net gains of $422 million, or $0.57 per share, from the sale of the company’s branded pharmaceuticals business in Europe, net of other various special items (a-c). Excluding the impact of these items, first quarter 2008 earnings per share increased 7.8 percent.

“Our first-quarter results demonstrate the strength of 3M’s global presence and the power of our diverse business portfolio,” said George W. Buckley, 3M chairman, president and CEO. “Two-thirds of our sales came from our international subsidiaries, and growth in many developing economies enabled us to overcome economic challenges in the U.S. and to fund investments to secure the future of our enduring franchises. I applaud the efforts and dedication of 3M employees worldwide for delivering these results.”

Four of the company’s six global businesses achieved double-digit profit growth in the quarter, namely Industrial and Transportation, Health Care, Safety Security and Protection Services, and Electro and Communications, which more than offset profit declines in 3M’s Consumer and Office and Display and Graphics businesses.

Buckley continued. “While economic conditions are uncertain, we remain focused on critical growth drivers including 3M’s world-renowned research and development capability, continued investment in our many enduring franchises, strategic acquisitions and new manufacturing plants that will improve our ability to serve customers. We will continue to balance growth and operational excellence in order to meet our commitments to our shareholders and to our customers around the world.”

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, and diluted earnings per share measures that exclude 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. 3M had no special items for the three months ended March 31, 2008.

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, 2007.

	Three-months ended Mar. 31, 2007
	Operating income			Net income			Diluted earnings per share
Reported GAAP measure	$	2,101		$	1,368		$	1.85

Special items:
Gain on sale of pharmaceuticals business in Europe (a)	(786		)	(506		)	(0.68		)
Restructuring actions (b)	12			9			0.01
Environmental liabilities (c)	121			75			0.10
Adjusted Non-GAAP measure	$	1,448		$	946		$	1.28

(a) In January 2007, 3M completed the sale of its global branded pharmaceuticals business in Europe. 3M received proceeds of $817 million from this transaction and recognized a pre-tax gain of $786 million in the first quarter of 2007.

(b) During the fourth quarter of 2006 and first six months of 2007, management approved and committed to undertake restructuring actions. In the first quarter of 2007 the Company recorded a net pre-tax restructuring charge of $12 million. The Company incurred pre-tax restructuring expenses, primarily fixed and intangible asset impairments related to the Electro and Communications segment of $19 million. In the Health Care segment, employee-related restructuring liabilities were adjusted to reflect current estimates of Health Care employee-related restructuring costs that were recorded in 2006, resulting in a pre-tax benefit of $7 million.

(c) The Company increased its accrued environmental liabilities by $121 million pre-tax in the first quarter of 2007 to address remediation activities associated with perfluoronated compounds. This expense was recorded in selling, general and administrative expenses.

No adverse human health effects are caused by perfluoronated compounds at current levels of exposure. This conclusion is supported by a large body of research including laboratory studies and epidemiology studies of exposed employees. This research has been published in peer-reviewed scientific journals and shared with the EPA and global scientific-community.

In summary, special items on a combined basis benefited the three months ended March 31, 2007 reported GAAP operating income by $653 million, primarily related to the gain on sale of businesses. The gain on sale of businesses of $786 million (reported on a separate line of the Consolidated Statement of Income) and a special item benefit of $5 million for research, development and related expenses were partially offset by special items related to selling, general and administrative expenses ($128 million) and cost of sales ($10 million). Refer to 3M’s Annual Report on Form 10-K dated February 15, 2008, for further discussion of these previously disclosed items.

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, 2007. 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 2008. Segment information for all periods presented has been reclassified to reflect this new segment structure.

NON-GAAP MEASURES

Free Cash Flow:
Net cash provided by operating activities	$	997		$	580
Purchases of property, plant and equipment	(298		)	(304		)

Free Cash Flow (d)	$	699		$	276

(d) 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.

“Net cash provided by operating activities” and “Free Cash Flow” were negatively impacted in 2007 by the timing of cash tax payments associated with special items. Tax payments related to the sale of our global branded pharmaceuticals business negatively impacted total year 2007 net cash provided by operating activities and Free Cash Flow by $628 million, with the impacts by quarter as follows: fourth-quarter 2007 ($87 million), third-quarter 2007 ($37 million), second-quarter 2007 ($110 million) and first-quarter 2007 ($394 million).

OTHER NON-GAAP MEASURES:
Net Working Capital Turns (e)	4.9	5.0

(e) 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.
