-- Actions Reflect Confidence in Long-Term Growth Strategy --

The Board of Directors of 3M (NYSE: MMM) today declared a dividend on the company’s common stock of 55 cents per share for the first quarter of 2011, a 5 percent increase over the quarterly dividend paid in 2010. The dividend is payable on March 12, 2011, to shareholders of record at the close of business on February 18, 2011.

The board also authorized the repurchase of up to $7 billion of 3M’s outstanding common stock, replacing the company’s existing repurchase program. The authorization has no pre-established closing date.

“Today’s announcement reflects the strength of our business model and our confidence in the future,” said George W. Buckley, 3M chairman, president and CEO. “Our strong balance sheet and outstanding free cash flow allow us to fund growth investments and continue our legacy of returning significant cash to shareholders.”

Over the past five years, the company has returned over $15 billion to shareholders through a combination of dividends and share repurchases. 3M has paid dividends to its shareholders without interruption for more than 94 years.

The 3M Board of Directors also set March 11, 2011, 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 10, 2011.
