THE SHARES OF COMMON STOCK ARE NOT BEING OFFERED IN ANY JURISDICTION WHERE THE OFFER IS NOT PERMITTED. THE COMPANY 3M was incorporated in 1929 under the laws of the State of Delaware to continue operations, begun in 1902, of a Minnesota corporation originally named Minnesota Mining and Manufacturing Company. In April 2002, the company's name was changed to 3M Company. 3M's principal executive offices are located at 3M Center, St. Paul, Minnesota 55144 (telephone: 651-733-1110). 3M is an integrated enterprise characterized by substantial intercompany cooperation in research, manufacturing and marketing of products. 3M's business has developed from its research and technology in coating and bonding for coated abrasives, the company's original product. Coating and bonding is the process of applying one material to another, such as 2 abrasive granules to paper or cloth (coated abrasives), adhesives to a backing (pressure-sensitive tapes), ceramic coating to granular mineral (roofing granules), glass beads to plastic backing (reflective sheeting), and low-tack adhesives to paper (repositionable notes). 3M is among the leading manufacturers of products for many of the markets it serves. In all cases, 3M products are subject to direct or indirect competition. Most 3M products involve expertise in product development, manufacturing and marketing, and are subject to competition from products manufactured and sold by other technically oriented companies. Our strategic business units have been aggregated into six reportable segments: Industrial Markets, Health Care Markets, Transportation, Graphics and Safety Markets, Consumer and Office Markets, Electro and Communications Markets and Specialty Material Markets. These segments bring together common or related 3M technologies, enhancing the development of innovative products and services and providing for efficient sharing of business resources. These segments have worldwide responsibility for virtually all 3M product lines. A few miscellaneous businesses and staff-sponsored products, as well as various corporate assets and corporate overhead expenses, are not assigned to the segments. RISK FACTORS An investment in our common stock involves a number of risks, some of which could be substantial and are inherent in our businesses. You should consider the following factors carefully before deciding to purchase shares of our common stock. Additional risks not presently known to 3M or that 3M currently deems immaterial may also impair 3M's business operations. Actual future results and trends may differ materially from historical results or those anticipated depending on a variety of factors, including, but not limited to, the following: 3M'S BUSINESS MAY BE AFFECTED BY THE EFFECTS OF, AND CHANGES IN, WORLDWIDE ECONOMIC CONDITIONS - 3M operates in more than 60 countries and derives more than half of its revenues from sales outside the United States. 3M's business may be affected by factors in other countries that are beyond its control, such as downturns in economic activity in a specific country or region; social, political or labor conditions in a specific country or region; or potential adverse foreign tax consequences. FOREIGN CURRENCY EXCHANGE RATES AND FLUCTUATIONS IN THOSE RATES MAY AFFECT 3M'S ABILITY TO REALIZE PROJECTED GROWTH RATES IN ITS SALES AND NET EARNINGS AND ITS RESULTS OF OPERATIONS. - Because 3M derives more than half of its revenues from sales outside the United States, 3M's ability to realize projected growth rates in its sales and net earnings and its results of operations could be adversely affected if the United States dollar strengthens significantly against foreign currencies. 3M'S GROWTH OBJECTIVES ARE LARGELY DEPENDENT ON THE TIMING AND MARKET ACCEPTANCE OF ITS NEW PRODUCT OFFERINGS.- 3M's growth objectives are largely dependent on its ability to renew its pipeline of new products and to bring those products to market. This ability may be adversely affected by difficulties or delays in product development, such as the inability to: o identify viable new products; o successfully complete clinical trials and obtain regulatory approvals; o obtain adequate intellectual property protection; or 3 o gain market acceptance of new products. 3M'S FUTURE RESULTS ARE SUBJECT TO FLUCTUATIONS IN THE COSTS OF PURCHASED COMPONENTS AND MATERIALS DUE TO MARKET DEMAND, CURRENCY EXCHANGE RISKS, SHORTAGES AND OTHER FACTORS. - 3M depends on various components and materials for the manufacturing of its products. Although 3M has not experienced any difficulty in obtaining components and materials, it is possible that any of its supplier relationships could be terminated in the future. Any sustained interruption in 3M's receipt of adequate supplies could have a material adverse effect on it. In addition, while 3M has a process to minimize volatility in component and material pricing, no assurance can be given that 3M will be able to successfully manage price fluctuations due to market demand, currency risks, or shortages or that future price fluctuations will not have a material adverse effect on it. 3M'S ACQUISITIONS, DIVESTITURES AND STRATEGIC ALLIANCES MAY NOT BE BENEFICIAL TO 3M. - As part of 3M's strategy for growth, it has made and may continue to make acquisitions, divestitures and strategic alliances. However, there can be no assurance that any of these will be completed or beneficial to 3M. 3M IS THE SUBJECT OF VARIOUS LEGAL PROCEEDINGS. - The current estimates of the potential impact on 3M's consolidated financial position, results of operations and cash flows for its legal proceedings are predictions made by 3M about the future and should be considered forward-looking statements. These estimates could change in the future. 3M and some of its subsidiaries are named as defendants in a number of actions, governmental proceedings and claims, including environmental proceedings and products liability claims involving products now or formerly manufactured and sold by 3M. As for products liability claims, as reported in its Annual Report on Form 10-K for the year ended December 31, 2001, 3M and various other companies have been named as defendants in a number of claims and lawsuits the vast majority of which purportedly relate to the alleged use of company's mask and respirator products and seek damages from the company and other defendants for alleged personal injury from occupational exposure to asbestos or, less frequently, silica found in products manufactured by other defendants. The remaining lawsuits and claims generally allege personal injury from occupational exposure to asbestos from unspecified products claimed to have been manufactured by the company or other defendants and/or from specialty products containing asbestos manufactured by the company and/or other defendants many years ago. In some actions, the claimants seek damages as well as other relief, which, if granted, would require substantial expenditures. 3M has accrued various liabilities, which represent reasonable estimates of its probable liabilities for these matters. 3M also has recorded receivables for the probable amount of insurance recoverable with respect to these matters. For a more detailed discussion of legal proceedings involving 3M, see the discussion of "Legal Proceedings" in Part II, Item 1 of 3M's Quarterly Report on Form 10-Q for the period ended September 30, 2002, which is incorporated by reference into this prospectus.

USE OF PROCEEDS All net proceeds from the sale of the common stock covered by this prospectus will go to the selling stockholders who offer and sell their shares. We will not receive any proceeds from the sale of the common stock by the selling stockholders. PLAN OF DISTRIBUTION 3M is registering 278,979 shares of our common stock (the "Shares") on behalf of the selling stockholders who may sell the Shares from time to time. The selling stockholders will act independently of 3M in making decisions with respect to the timing, manner and size of each sale. The sales may be made on one or more exchanges or otherwise, at prices and at terms then prevailing or at prices related to the then current market price, or in negotiated transactions. The selling stockholders may effect such transactions by selling the Shares to or through broker-dealers. The Shares may be sold by one or more of, or a combination of, the following: o a block trade in which a broker-dealer will attempt to sell the Shares as agent but may position and resell a portion of the block as principal to facilitate the transaction, o purchases by a broker-dealer as principal and resale by such broker-dealer for its account, o ordinary brokerage transactions and transactions in which the broker solicits purchasers, and When selling the Shares, the selling stockholders may enter into hedging transactions. For example, the selling stockholders may: o enter into transactions involving short sales of the Shares by broker-dealers; o sell Shares short themselves and deliver the Shares registered hereby to settle such short sales or to close out stock loans incurred in connection with their short positions; o enter into option or other types of transactions that require the selling stockholder to deliver Shares to a broker-dealer or other person, who will then resell or transfer the Shares under this prospectus; or 6 o loan or pledge the Shares to a broker-dealer or other person, who may sell the loaned shares or, in the event of default, sell the pledged shares. The selling stockholders may negotiate and pay broker-dealers or other persons commissions, discounts or concessions for their services. Broker-dealers or other persons engaged by the selling shareholders may allow other broker-dealers or other persons to participate in resales. However, the selling stockholders and any broker-dealers or such other persons involved in the sale or resale of the Shares may qualify as "underwriters" within the meaning of the Section 2(a)(11) of the Securities Act. In addition, the broker-dealers' or their affiliates' commissions, discounts or concessions may qualify as underwriters' compensation under the Securities Act. If the selling stockholders qualify as "underwriters," they will be subject to the prospectus delivery requirements of Section 5(b)(2) of the Securities Act. In addition to selling their Shares under this prospectus, the selling stockholders may: o agree to indemnify any broker-dealer or agent against certain liabilities related to the selling of the Shares, including liabilities arising under the Securities Act; o transfer their Shares in other ways not involving market makers or established trading markets, including directly by gift, distribution, or other transfer; or o sell their Shares under Rule 144 of the Securities Act rather than under this prospectus, if the transaction meets the requirements of Rule 144. The selling stockholders have advised 3M that they have not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of the Shares and that there is no underwriter or coordinating broker acting in connection with the proposed sale of Shares by selling stockholders. The Shares may be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states the Shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the Shares may not simultaneously engage in market making activities with respect to our common stock for a period of one business day prior to the commencement of such distribution. In addition, each selling stockholder will be subject to applicable provisions of the Exchange Act and the associated rules and regulations under the Exchange Act, including Regulation M, which provisions may limit the timing of purchases and sales of Shares by the selling stockholders. 3M will make copies of this prospectus available to the selling stockholders and has informed them of the need for delivery of copies of this prospectus to purchasers at or prior to the time of any sale of the Shares. Additional information related to the selling stockholders and the plan of distribution may be provided in one or more supplemental prospectuses. 3M will bear all costs, expenses and fees in connection with the registration of the 7 Shares. The selling stockholders will bear all commissions and discounts, if any, attributable to the sales of the Shares. SELLING STOCKHOLDERS The following table sets forth the number of Shares owned by the selling stockholders. In the past three years, none of the selling stockholders has had a material relationship with 3M. No estimate can be given as to the number of Shares that will be held by the selling stockholders after completion of this offering because the selling stockholders may offer all or some of the Shares and because the selling stockholders have advised us that there currently are no agreements, arrangements or understandings with respect to the sale of any of the Shares. The Shares covered by this prospectus may be offered from time to time by the selling stockholders named below. ----------------------------------------------------------------------------------------------- SELLING STOCKHOLDERS SHARES SHARES WHICH BENEFICIALLY MAY BE SOLD OWNED PRIOR TO PURSUANT TO THIS THE OFFERING(1) PROSPECTUS(2) ----------------------------------------------------------------------------------------------- Richard L.

(2) The registration statement of which this prospectus forms a part also shall cover any additional shares of our common stock which become issuable in connection with the Shares by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the receipt of consideration which results in an increase in the number of 3M's outstanding shares of common stock. LEGAL MATTERS Gregg M. Larson, who is our Assistant General Counsel, or another one of our lawyers, will issue an opinion about the validity of the Shares offered in this prospectus, as well as other relevant legal matters. Mr. Larson beneficially owns, or has options to acquire, a number of shares of our common stock, which represents less than 1% of the total outstanding common stock. EXPERTS The audited financial statements incorporated into this prospectus by reference to our Annual Report on Form 10-K for the year ended December 31, 2001 have been so incorporated 8 in reliance on the report of PricewaterhouseCoopers LLP, independent accountants, given on the authority of that firm as experts in auditing and accounting. INDEPENDENT ACCOUNTANTS With respect to our unaudited interim financial information for the three-month periods ended March 31, 2002 and 2001, the three- and six-month periods ended June 30, 2002 and 2001, and the three- and nine-month periods ended September 30, 2002 and 2001, incorporated by reference in this prospectus, PricewaterhouseCoopers LLP have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However their separate reports dated April 22, 2002, July 22, 2002, and October 21, 2002, and incorporated by reference herein, state that they did not audit and they do not express an opinion on that unaudited interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. PricewaterhouseCoopers LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim financial information because that report is not a "report" or a "part" of the registration statement prepared or certified by PricewaterhouseCoopers LLP within the meaning of Sections 7 and 11 of the Securities Act.
