UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM 8-K CURRENT REPORT Pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 Date of Report: May 23, 2003 (Date of earliest event reported) 3M COMPANY (Exact name of registrant as specified in its charter) File No. 1-3285 (Commission File Number) Delaware 41-0417775 (State of Incorporation) (I.R.S. Employer Identification Number) 3M Center 55144-1000 St. Paul, Minnesota (Zip Code) (Address of principal executive offices) Registrant's telephone, including area code: (651) 733-1110 ITEM 5. OTHER EVENTS 3M announced in September 2002 a strategic realignment of its organization, designed to achieve faster growth and a closer focus on its markets and customers. This realignment resulted in seven reportable business segments compared to the previous structure of six reportable business segments. These structural changes were driven by 3M's strategic planning process and represent an important step toward access to its larger and faster-growing markets. Internal management reporting for the new reportable business segments commenced January 1, 2003. On April 4, 2003, 3M in a Current Report on Form 8-K, furnished supplemental unaudited financial information on both an annual and quarterly basis for the years ended December 31, 2002, 2001 and 2000, reflecting the realigned segments. The company reported comparative results under this new structure in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2003 (the "Quarterly Report"). This Current Report on Form 8-K provides an update to 3M's Annual Report on Form 10-K for the year ended December 31, 2002 (the "Annual Report"). This update relates only to segments and non-GAAP financial measures. Since this update relates only to these items, this document should be read with reference to the Quarterly Report, which describes significant developments since the preparation of the Annual Report. The segment information provided in Item 1, "Business", Item 8, Note 4, "Goodwill and Indefinite-Lived Intangible Assets", and Item 8, Note 12, "Business Segments" contained in 3M's Annual Report has been reclassified to reflect 3M's realigned segments. 3M has also updated its Management Discussion and Analysis (MD&A) to reflect this realignment. In addition, 3M has updated information, primarily in MD&A, to be consistent with the new requirements of Item 10 of Regulation S-K that became effective on March 28, 2003. New Item 10(e) of Regulation S-K regulates the use of non-GAAP financial measures in filings with the Securities and Exchange Commission on or after March 28, 2003. The company will now be able to incorporate the updated information by reference into future registration statements or post-effective amendments to existing registration statements. The updated information is included in Item 7 of this Current Report on Form 8-K. ITEM 7.
