AMETEK EXPECTS TO REPORT RECORD EARNINGS WHICH ARE ABOVE PRIOR COMPANY GUIDANCE

INCREASES FIRST QUARTER EARNINGS GUIDANCE TO $0.55 — $0.56
PER DILUTED SHARE

—Raises Full Year 2011 Estimate to $2.20 to $2.25 Per Diluted Share—

Berwyn, PA, April 15, 2011 – AMETEK, Inc. (NYSE: AME) today announced it expects its first quarter results to substantially exceed its prior guidance. The Company now expects first quarter diluted earnings per share to be approximately $0.55 to $0.56, up from its previous guidance of $0.46 to $0.48 per diluted share. First quarter sales are expected to be up approximately 29% over the $556.7 million recorded in the first quarter of 2010.

“AMETEK had a strong quarter that surpassed our expectations,” stated Frank S. Hermance, AMETEK Chairman and Chief Executive Officer. “Orders in the quarter were up approximately 37% with broad-based strength evident in most of our markets. This order strength translated into strong top-line performance and, coupled with a lower cost structure, drove the excellent bottom-line performance. Earnings are expected to be significantly above our previous guidance, with diluted earnings per share up 53% to 56% over the first quarter of 2010. These results will establish quarterly records for orders, sales and diluted earnings per share.”

“Our markets overall continue to show excellent growth as evidenced by our strong order input this year. Given the strong first quarter results and our positive outlook for the balance of the year, we have raised our full year 2011 estimated earnings to a range of $2.20 to $2.25 per diluted share, up from our previous guidance of $2.00 to $2.07 per diluted share. Our revised guidance represents a 25% to 28% improvement over 2010,” commented Mr. Hermance.

Earnings for the second quarter are expected to be between $0.53 and $0.55 per diluted share.

Included in both the full year and second quarter guidance is $0.02 per diluted share of costs associated with the performance-based, accelerated vesting of restricted stock, which resulted from a doubling of our stock price since the April 23, 2009 grant date.
