Oberhelman is also chairman of the Caterpillar board and he will relinquish that to Dave Calhoun, also on March 31.
During his time with the company Oberhelman saw both the highs and the lows. He led the company to its highest sales and revenue peak in its 91-year history in 2012 and has presided over its fall as the mining industry went into a massive downturn.
One of Oberhelman’s main moves as Caterpillar CEO was the company’s purchase of Bucyrus for $US7.6 billion in late 2010.
That deal started to look a bit sick as the industry went the downturn bit. It looked even worse this year when Komatsu lodged a bid for Joy – a similar sized company to Bucyrus with very similar offerings – of just $3.7 billion.
Oberhelman admitted, when asked by Australia’s Mining Monthly that, with the benefit of hindsight, Caterpillar probably paid too much for Bucyrus.
However, he did not regret the deal because of the extra capabilities it brought to the company and also because he believes mining will enjoy a renaissance in the not too distant future.
