BOSTON - PerkinElmer, Inc. (NYSE: PKI) today announced first quarter 2003 GAAP
earnings per share from continuing operations of $.03 on revenue of $358.4
million, compared to a GAAP loss per share from continuing operations of ($.17)
and revenue of $346.3 million in the first quarter of 2002. The first quarter
2003 results reflect intangibles amortization of $7.2 million, or approximately
$.04 per share. These earnings are consistent with the company's January 2003
estimate for the quarter of $.02 to $.05 per share on a GAAP basis.

"We were pleased to deliver earnings per share and cash flow that are
significantly improved from last year and within the range of our previous
guidance," said Gregory L. Summe, chairman and CEO of the Company. "The
integration of our Life and Analytical Sciences unit is progressing well and our
plans are on track to meet or exceed our targeted cost reductions," added Summe.

Revenue from continuing operations in the first quarter of 2003 was $358.4
million, up 4% from the same period of 2002. The comparative increase was driven
by 20% growth in Optoelectronics and 11% growth in Analytical Instruments,
offset by revenue declines in Life Sciences and Fluid Sciences.

down 11% compared to revenue of $116.8 million for the first quarter of 2002.
Strong revenue growth in genetic screening during the quarter and overall

of 2003, representing an 11% increase compared to revenue of $115.5 million for

applications and pharmaceutical QA/QC. The segment's GAAP operating profit for

OPTOELECTRONICS reported revenue of $83.3 million for the first quarter of 2003,
an increase of 20% from revenue of $69.3 million for the first quarter of 2002.
Strong double-digit growth in revenues of digital imaging and lighting products
drove the increase during the quarter. The segment's GAAP operating profit was
$8.7 million during the first quarter of 2003 versus an operating loss of $22.6
million for the comparable period of 2002. The operating profit for the first
quarter of 2003 included intangibles amortization of $.3 million. The operating

FLUID SCIENCES reported revenue of $42.9 million for the first quarter of 2003,
representing a decline of 4% compared to revenue of $44.6 million for the first
quarter in 2002. Both the aerospace and semiconductor end markets were depressed
during the quarter. The segment's GAAP operating profit for the first quarter of

million. The first quarter of 2002 results included intangibles amortization of

on our strategy of reducing costs, accelerating new products, and driving cash
flow," added Summe.
