Excluding restructuring charges, net income rose to $161 million, or $1.03 a share, from $99 million, or 68 cents a share. On that basis, analysts had expected the company to earn $1.02 a share.
Sales rose 19% to $2.4 billion, as revenue was stronger than expected in the hydraulics and truck markets as well as the residential electrical market. Although the company anticipates this strength to continue, nonresidential construction and European markets segments are "not expecting significant growth" until next year.
However, the company boosted third-quarter earnings guidance to $1.05 to $1.15 a share and full-year guidance to between $4 and $4.15 a share.
Analysts had been expecting the company to earn $1.03 in the third quarter and $3.99 for the year.
