ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

         On October 20, 2003, 3M Company issued a press release reporting its
earnings for the quarter ended September 30, 2003 (furnished hereunder as
Exhibit 99.1).

         The information contained in this Current Report shall not be deemed to
be "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934
(the "Exchange Act") or otherwise subject to the liabilities of that section,
nor shall it be incorporated by reference into a filing under the Securities Act
of 1933, or the Exchange Act, except as shall be expressly set forth by specific
reference in such a filing.

         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. The company will continue
to provide reconciliations of its disclosed 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.
Special items represent significant charges or credits that are important to an
understanding of the company's ongoing operations. Earnings per share and other
amounts before special items are not measures recognized under U.S. generally
accepted accounting principles. The determination of special items may not be
comparable to similarly titled measures used by other companies.


                                    SIGNATURE

         Pursuant to the requirements of the Securities Exchange Act of 1934,
the Registrant has duly caused this report to be signed on its behalf by the
undersigned thereunto duly authorized.

                                                         3M COMPANY
