Operating income margins were 29.6 percent, compared to 30.2 percent in 2010, with this decrease due in part to growth investments in the health information systems and infection prevention businesses. 3M also invested in emerging markets to improve market penetration levels.

Year 2012 results:

 

Sales in Consumer and Office totaled $4.3 billion, up 3.9 percent in U.S. dollars. Organic local-currency sales increased 3.8 percent, acquisitions added 2.0 percent, and foreign currency translation reduced sales by 1.9 percent. Organic local-currency sales growth was led by the consumer health care and construction and home improvement businesses.

The addition of GPI’s products expands 3M’s product portfolio in core and complementary categories in the construction and home improvement markets.
