DOVER REPORTS FIRST QUARTER 2006 RESULTS

New York, New York, April 27, 2006 — Dover Corporation (NYSE: DOV) announced that for the first quarter ended March 31, 2006, it had earnings from continuing operations of $133.5 million or $0.65 diluted earnings per share (“EPS”), compared to $95.4 million or $0.47 EPS from continuing operations in the prior-year period, representing an increase of 40%. Revenue for the first quarter of 2006 was a record $1,668.4 million, an increase of 22% over the prior-year period. Earnings from continuing operations for the first quarter of 2006 included $0.025 EPS related to the expensing of stock options and appreciation rights.

Net earnings for the first quarter of 2006 were $203.8 million or $0.99 EPS, including earnings from discontinued operations of $70.3 million or $0.34 EPS, compared to net earnings of $98.1 million or $0.48 EPS for the same period of 2005, which included earnings from discontinued operations of $2.7 million or $0.01 EPS. The increase in earnings from discontinued operations for the first quarter of 2006 included a gain on the previously announced sale of Tranter PHE of approximately $85.1 million, net of tax, partially offset by impairments related to businesses discontinued during the quarter of approximately $14.4 million, net of tax, and a loss related to a business sold in the Electronics segment of $2.2 million, net of tax.

During the three months ended March 31, 2006, the Company discontinued and sold one business in the Electronics segment and discontinued one operating company in the Resources segment, which is comprised of two businesses. For the quarter ended March 31, 2006, these businesses had revenue of $14.7 million and no impact on operating earnings, excluding gains/losses on sales and write-offs. All continuing operations information has been restated to reflect the discontinuance of these companies.

Commenting on the Company’s results and the current outlook, Dover’s Chief Executive Officer and President, Ronald L. Hoffman, said: “Dover had a great first quarter as all of our segments showed positive improvements in revenue, earnings and margins. The internal performance improvements and increased sales resulted in 24.2% operating leverage. We are particularly pleased with our strong organic revenue growth of 16.3%, with acquisitions contributing 7.4% towards the total revenue increase. Record bookings and backlog were both up double digits compared to last year and were very broadly dispersed among all our segments. Quarterly free cash flow of $73.5 million was much improved over the prior year period, reflecting our emphasis on “Performance Counts” and the five metrics. Based on continued strength in the broad industrial markets we serve, as well as our acquisition pipeline, we feel good about the second quarter and optimistic about 2006 being another year of strong performance.”
