Sales in Industrial totaled $10.6 billion, up 6.5 percent in U.S. dollars. Organic local-currency sales increased 4.6 percent, acquisitions added 3.6 percent, and foreign currency translation reduced sales by 1.7 percent. On an organic local-currency basis, all of Industrial’s businesses experienced positive sales growth in 2013, led by aerospace, automotive OEM, 3M Purification Inc. (filtration products), and industrial adhesives and tapes. Acquisition growth related to the 2012 acquisition of Ceradyne, Inc. (Ceradyne). As disclosed in Note 2, in November 2012, 3M acquired Ceradyne, which is headquartered in Costa Mesa, California. Ceradyne is involved in the development and production of advanced technical ceramics for demanding applications in the automotive, oil and gas, solar, industrial, electronics and defense industries.

 

Geographically, organic local-currency sales increased 8 percent in Latin America/Canada, 5 percent in the United States, 4 percent in EMEA, and 3 percent in Asia Pacific.

 

Operating income was $2.3 billion in 2013, up 2.7 percent year-on-year. Operating income margins decreased by 0.8 percentage points to 21.7 percent. This decline in margins largely related to the Ceradyne acquisition, which reduced 2013 operating income margins by 0.7 percentage points.
