3M CEO: Core Businesses Continue to Drive Sales and Profit Growth.

ST. PAUL, Minn. -- At a meeting in St. Paul today, 3M chairman, president and CEO George Buckley told institutional investors and investment analysts that the company's strategy to innovate and invest in 3M's core is succeeding and delivering results.

"Our core businesses are strong and getting stronger," Buckley said. "We are rejuvenating them through consistent investment in technology development, acquisitions and international expansion."

Buckley highlighted 3M ventures in markets such as solar energy, industrial air and water filtration, mining and minerals extraction, oil and gas, and food safety.

"We will capitalize on these emerging opportunities by acquiring new-to-3M technologies and businesses to complement our technology and product portfolio," he said.
