Paoli, PA, January 26, 2005 – AMETEK Inc. (NYSE: AME) today announced fourth quarter and full-year results that established records for sales, operating income, net income and diluted earnings per share. The Company also introduced 2005 earnings guidance of $1.85 to $1.95 per diluted share, a 13% to 20% increase over 2004.

Fourth Quarter Results

AMETEK’s fourth quarter 2004 sales of $326.3 million were up 17% over the same period of 2003. Operating income for the fourth quarter of 2004 was $54.8 million, a 31% increase from the $41.9 million recorded in the same period of 2003. Net income in the fourth quarter of 2004 increased 29% to $31.4 million, or $.45 per diluted share, from fourth quarter 2003 levels of $24.4 million, or $.36 per diluted share. Sales, operating income, net income, and diluted earnings per share were quarterly records.

Full-Year Results

AMETEK achieved 2004 sales of $1.23 billion, up 13% from year 2003 results. Operating income of $196.2 million was up 25% from $156.8 million for 2003. Net income grew to $112.7 million, up 28% from the $87.8 million earned in 2003, and diluted earnings per share of $1.63 were up 25% from $1.30 per share in 2003. Sales, operating income, net income, and diluted earnings per share were full-year records.

“AMETEK had a tremendous 2004,” noted Frank S. Hermance, AMETEK Chairman and Chief Executive Officer. “Solid internal growth in each of our segments and contributions from acquired businesses enabled us to post a double-digit sales increase. Our record earnings performance benefited from an improved mix of businesses and our focused operational excellence initiatives.”

Electronic Instrument Groups (EIG)

For the 2004 fourth quarter, EIG sales increased 21% to $184.3 million. Operating income for the fourth quarter was $40.2 million, compared with $28.2 million in the fourth quarter of 2003, an increase of 42%. Operating margins for the quarter improved to 21.8% from 18.6% in the fourth quarter of 2003.

Included in EIG’s fourth quarter results were pre-tax gains totaling $3.5 million from the final settlement of insurance claims related to a flood at one of its manufacturing facilities and a gain on the sale of another facility. These gains increased operating margins 190 basis points.

“EIG sales were up in the quarter on internal growth across the group, including strong growth in our long cycle aerospace and power businesses and the contribution from the Taylor Hobson acquisition. EIG margins were up sharply as we captured the leverage in our business model,” added Mr. Hermance.

For the year, EIG sales of $667.4 million were up 19% from 2003 sales of $561.9 million. Operating income was $126.4 million for 2004, up 33% versus $95.0 million earned in 2003. Operating margins were 18.9% in 2004, up from 16.9% in 2003.

Electromechanical Group (EMG)

For the fourth quarter of 2004, EMG’s sales were $141.9 million, an 11% increase over the same period of 2003. Operating income of $21.9 million was up 15% from the $19.0 million recorded in the same period of 2003. Operating margins for the quarter were 15.4%, compared with 14.9% in the fourth quarter of 2003.

Included in the quarter’s results were higher than normal expenses of $2.5 million, primarily associated with the movement of production to low-cost manufacturing locales. These expenses reduced operating margins by 180 basis points.

“EMG fourth quarter sales were up on good internal growth in both our differentiated businesses and our cost-driven motor businesses and the contribution from Hughes-Treitler. Operating margins were up nicely, driven by operational improvements across the group and the contribution of the Hughes-Treitler acquisition,” noted Mr. Hermance.

For the year, EMG’s sales increased 7% to $564.9 million, compared with $529.7 million in 2003. Operating income was $94.3 million for 2004, up 12% from the $84.2 million earned in 2003. Operating margins increased to 16.7% in 2004, compared with 15.9% in 2003.

2005 Outlook

“For 2005 we expect revenues to be up approximately 10% on solid internal growth in each of our two groups and the full-year benefits from our Taylor Hobson and Hughes-Treitler acquisitions,” commented Mr. Hermance. “Earnings are estimated to be approximately $1.85 to $1.95 per diluted share, an increase of 13% to 20% over 2004, driven by the top-line growth and our continued focus on operational excellence, including the movement of additional manufacturing to low cost locales.”

“Our first quarter 2005 sales are expected to be up low double-digits from last year’s first quarter. We estimate our earnings to be approximately $0.43 to $0.45 per diluted share, an increase of 19% to 25% over last year’s first quarter,” concluded Mr. Hermance.
