DOWNERS GROVE, IL – Dover Corp. said first-quarter revenue was $2 billion, up 24% over the prior-year period.

Net earnings were $194.9 million, up 80.3% compared to the same period of 2010.

Earnings from continuing operations were $183.3 million, up 51% year-over-year.

“Revenue, earnings, bookings and backlog were all up significantly over the prior year. Revenue growth of 24% was above our expectations and largely driven by improving end-markets served by Industrial Products and a very strong energy market. We closed four acquisitions during the quarter, the largest being Harbison-Fischer, and our companies continued to record solid order rates through the first quarter, resulting in a strong book-to-bill of 1.15,” said president and CEO Robert A. Livingston.

The firm expects full-year 2011 revenue growth of 12% to 14%.

Dover provides components, equipment, specialty systems and support services for applications in the industrial products, engineered systems, fluid management and electronic technologies markets.
