"3M turned in another strong performance in 2004, and we're confident in our ability to sustain solid, broad-based growth," said W. James McNerney, Jr., chairman of the board and CEO. "Thanks to our performance -- reflected in double-digit earnings growth and strong cash flow -- we're able to continue to invest in growth, while also providing our shareholders with steady and increasing dividends," McNerney said.

In 2004, 3M generated $3.0 billion of net income, a 24.4 percent increase from 2003. Sales reached the $20 billion milestone, an increase of nearly 10 percent from 2003.
