Forward Looking Statements
This presentation contains forward-looking information about 3M’s financial results and estimates
and business prospects that involve substantial risks and uncertainties. You can identify these
statements by the use of words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,”
“believe,” “will,” “target,” “forecast” and other words and terms of similar meaning in connection with
any discussion of future operating or financial performance or business plans or prospects. Among
the factors that could cause actual results to differ materially are the following: (1) worldwide
economic conditions; (2) competitive conditions and customer preferences; (3) foreign currency
exchange rates and fluctuations in those rates; (4) the timing and acceptance of new product
offerings; (5) the availability and cost of purchased components, compounds, raw materials and
energy (including oil and natural gas and their derivatives) due to shortages, increased demand or
supply interruptions (including those caused by natural and other disasters and other events); (6) the
impact of acquisitions, strategic alliances, divestitures, and other unusual events resulting from
portfolio management actions and other evolving business strategies, and possible organizational
restructuring; (7) generating fewer productivity improvements than estimated; and (8) legal
proceedings, including significant developments that could occur in the legal and regulatory
proceedings described in the company’s Annual Report on Form 10-K for the year ended December
31, 2007 and its subsequent Quarterly Reports on Form 10-Q (the “Reports”). Changes in such
assumptions or factors could produce significantly different results. A further description of these
factors is located in the Reports under “Risk Factors” in Part I, Item 1A (Annual Report) and in Part
II, Item 1A (Quarterly Report). The information contained in this presentation is as of the date
indicated. The company assumes no obligation to update any forward-looking statements contained
in this presentation as a result of new information or future events or developments.
