ITEM 5. OTHER EVENTS.

     1.   On August 11, 2003, the Board of Directors of 3M Company ("Company")
          declared a two-for-one stock split ("Stock Split") of the issued
          shares of common stock having a par value of $0.01 per share ("Common
          Stock"). The Stock Split will be in the form of a stock dividend of
          one additional share for each share owned by shareholders of record
          and each share held in treasury as of the close of business on
          September 22, 2003 and will be distributed to such holders on
          September 29, 2003.

          The Board of Directors also declared a cash dividend on the pre-split
          shares of $0.66 per share, payable on September 12, 2003 to the
          holders of record of shares of Common Stock as of the close of
          business on August 22, 2003.


     2.   Pursuant to Rule 416 of the Securities Act of 1933, as amended,
          effective on the September 22, 2003 record date for the Stock Split,
          all effective registration statements of Common Stock shall be deemed
          to cover the additional securities resulting from the Stock Split. The
          following are among the registration statements covered by Rule 416:
          Registration Nos. 333-103234, 333-98163, 333-49830, 333-42660,
          333-101751, 333-101727, 333-44692, 333-44760, 333-30691, 333-30689,
          333-26957, 33-58767, and 33-49842.

     3.   The Company also indicated in the press release that the third quarter
          of 2003 earnings per share, scheduled to be announced on October 20,
          2003, will be reported on a split-adjusted basis. Reflecting the Stock
          Split, the Company's previously announced third quarter earnings
          outlook of $1.56 to $1.60 per share will now be $0.78 to $0.80 per
          share. Accordingly, the Company's previously stated earnings
          expectation for full-year 2003 of $5.75 to $5.90 per share on a
          reported basis will now be $2.88 to $2.95 per share. Excluding special
          items (a), 2003 earnings expectations of $5.90 to $6.05 per share will
          now be $2.95 to $3.02 per share, again reflecting the Stock Split.

               (a) As previously announced by 3M on March 26, 2003, a court
               issued an adverse ruling associated with a lawsuit filed against
               3M in 1997 by LePage's Inc. During the first quarter of 2003, 3M
               recorded pretax charges of $93 million ($58 million after-tax)
               related to this proceeding.

     4.   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 has provided 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. 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.

                                                                      Exhibit 99


FOR IMMEDIATE RELEASE

3M Declares Two-For-One Stock Split, Quarterly Dividend

ST. PAUL, MINN. -- Aug. 11, 2003 -- 3M (NYSE MMM) today announced that its Board
of Directors has declared a two-for-one split of the company's common stock. The
stock split will be in the form of a stock dividend to be distributed Sept. 29,
2003 to shareholders of record at the close of business on Sept. 22, 2003.

The company's Board of Directors also declared a quarterly cash dividend of 66
cents per share on a presplit basis, payable Sept. 12, 2003 to shareholders of
record on Aug. 22, 2003, the 348th consecutive quarterly dividend on 3M stock.

"The stock split reflects 3M's confidence in the company's ability to continue
to deliver solid results despite an ongoing cautious view of global markets,"
said W. James McNerney, Jr., chairman of the board and chief executive officer.
Prior to this action, the most recent 3M stock splits occurred in 1994, 1987 and
1972.

Third-quarter earnings per share, scheduled to be announced Oct. 20, will be
reported on a split-adjusted basis. Reflecting the split, the company's
previously announced Q3 earnings outlook of $1.56 to $1.60 per share will now be
$0.78 to $0.80 per share. Accordingly, the company's previously stated earnings
expectation for full-year 2003 of $5.75 to $5.90 per share on a reported basis
will now be $2.88 to $2.95 per share. Excluding special items (a), 2003 earnings
expectations of $5.90 to $6.05 per share will now be $2.95 to $3.02 per share,
again reflecting the split.

As of June 30, the company had 391,503,430 common shares outstanding and 123,745
shareholders of record.

(a) As previously announced by 3M on March 26, 2003, a court issued an adverse
ruling associated with a lawsuit filed against 3M in 1997 by LePage's Inc.
During the first quarter of 2003, 3M recorded pretax charges of $93 million ($58
million after-tax) related to this proceeding.
