Board Also Declares 49th Consecutive Annual Dividend Increase

ST. PAUL, Minn.--(BUSINESS WIRE)--3M today announced that its Board of Directors approved a new $7 billion two-year share repurchase authorization between Feb. 12, 2007, and Feb. 28, 2009, the largest in 3M’s history.

“While our first priority remains investing for growth, returning cash to our shareholders remains an integral part of our strategy,” said George W. Buckley, 3M chairman, president and CEO. “The strength of our operations and our confidence in 3M’s future continue to afford us the flexibility to do both.”

The Board also declared a quarterly dividend on 3M common stock of 48 cents per share, a 4.3 percent increase over the quarterly dividend paid in 2006. The dividend is payable March 12, 2007, to shareholders of record on Feb. 23, 2007. This marks the company’s 362nd consecutive quarterly dividend and the 49th consecutive year of 3M dividend increases.

During the calendar years 2004-2006, the company returned more than $10 billion in cash to shareholders through the combination of share repurchases and cash dividends.

As of Dec. 31, 2006, 3M had 734,362,802 common shares outstanding and 124,074 shareholders of record.

The 3M Board of Directors also set March 9, 2007 as the record date for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting of Stockholders to be held on Tuesday, May 8, 2007.
