AMETEK ANTICIPATES VERY STRONG SECOND QUARTER

INCREASES SECOND QUARTER EARNINGS GUIDANCE TO $.64 — $.65
PER DILUTED SHARE

—Raises Full Year 2006 Estimate to $2.42 to $2.46 per Diluted Share—

Paoli, PA, July 17, 2006 — AMETEK Inc. (NYSE: AME) today announced it expects its second quarter and full year 2006 results to substantially exceed its prior estimates.

The Company now expects second quarter diluted earnings per share to be approximately $.64 to $.65, up from its previous guidance of $.57 to $.59 per diluted share. Second quarter sales are expected to be in the range of $450 million, up approximately 28% from the $352.1 million for the second quarter of 2005.

“AMETEK had an outstanding quarter which surpassed our expectations,” stated Frank S. Hermance, AMETEK Chairman and Chief Executive Officer. “Strong internal growth in each of the Company’s two segments, combined with the contributions from acquired businesses drove the strong top-line growth. We translated this top-line growth into bottom-line performance, increasing diluted earnings per share 31% to 33% over last year’s second quarter,” he commented.

“Given our strong first half results and the expectation of continued strength in our markets, we have raised our full year 2006 estimated earnings to a range of $2.42 to $2.46 per diluted share, up from our previous guidance of $2.30 to $2.35 per diluted share,” commented Mr. Hermance.

Mr. Hermance also noted, “While the Department of Homeland Security’s failure to select AMETEK as a vendor for The Department’s Advanced Spectroscopic Portal Monitor program is a disappointment, AMETEK will continue to pursue other global opportunities for advanced radiation detection systems.”
