    WALTHAM, Mass.--(BUSINESS WIRE)--July 26, 2007--PerkinElmer, Inc.
(NYSE: PKI), a global leader in Health Sciences and Photonics markets,
today reported GAAP earnings per share from continuing operations of
$.28 on revenue of $437.3 million for the second quarter ended July 1,
2007. On a non-GAAP basis, which includes the adjustments noted in the
attached reconciliation, the Company announced adjusted earnings per
share for the second quarter 2007 of $.30, which was on the upper end
of the Company's forecasted range of $.28 to $.30.

    Second quarter 2007 revenue of $437.3 million increased 16% versus
the second quarter of 2006. Revenue growth was 17% in Life and
Analytical Sciences and 13% in Optoelectronics compared to the same
period last year. From an end market perspective, second quarter 2007
revenue from Health Sciences, which represented 85% of total revenues
for the quarter, increased 18% over the same period of 2006. This
increase was driven primarily by strong growth in genetic screening,
medical imaging, environmental and service. Foreign exchange and
acquisitions contributed 7% to second quarter 2007 revenue growth.

    "We were very pleased to deliver strong revenue, earnings and cash
flow growth for the second quarter. We are continuing to see the
benefits of our increased investments in R&D, marketing, and capital
equipment. Our recent acquisitions are also performing well," said
Gregory L. Summe, Chairman and CEO of PerkinElmer, Inc. "We expect to
carry this momentum into the second half of 2007 on the strength of
our new products and market development initiatives."

    GAAP operating profit during the second quarter of 2007 was $48.1
million. On a non-GAAP basis, which includes the adjustments noted in
the attached reconciliation, second quarter 2007 adjusted operating
profit was $50.8 million, or 11.6% as a percentage of GAAP revenue for
the quarter.

    The Company generated cash flow from operations of $69.7 million
in the second quarter of 2007, while increasing capital expenditures
by 32% over the same period of 2006. In addition, the Company
repurchased 3.5 million shares of its common stock for a cost of
approximately $87 million in the second quarter of 2007. This leaves
4.0 million shares remaining on the Company's stock repurchase
authorization.

    Life and Analytical Sciences reported revenue of $326.3 million
for the second quarter of 2007, up 17% from revenue of $278.5 million

    Adjusted Gross Margin and Adjusted Gross Margin Percentage

    We use the term "adjusted gross margin" to refer to GAAP gross
margin, excluding amortization of intangible assets, inventory fair
value adjustments related to business acquisitions, and stock option
expense. We use the related term "adjusted gross margin percentage" to
refer to adjusted gross margin as a percentage of GAAP revenue. We
believe that these non-GAAP measures, when taken together with our
GAAP financial measures, allow us and our investors to better measure
the performance of our investments in technology, to evaluate the
long-term profitability trends and to assess our ability to invest in
the business. We exclude amortization of intangible assets from these
measures because intangibles amortization charges do not represent
what our management and what we believe our investors consider to be
costs of producing our products and could distort the additional value
generated over the cost of producing those products. Inventory fair
value adjustments related to business acquisitions charges also do not
represent what our management and what we believe our investors
consider to be costs used in producing our products. In addition, we
exclude stock option expense from these measures because stock-based
compensation plans and the critical assumptions used to calculate the
expense vary dramatically between us and our peers, which we believe
makes comparisons of long-term operating performance trends difficult
for management and investors, and could result in overstating or
understating to our investors the costs used in producing our
products.

    Adjusted Selling, General and Administrative (SG&A) Expense and
Adjusted SG&A Percentage

    We use the term "adjusted SG&A expense" to refer to GAAP SG&A
expense, excluding amortization of intangible assets and stock option
expense. We use the related term "adjusted SG&A percentage" to refer
to adjusted SG&A expense as a percentage of GAAP revenue. We believe
that these non-GAAP measures, when taken together with our GAAP
financial measures, allow us and our investors to better measure the
cost of the internal operating structure, our ability to leverage that
structure and the level of investment required to grow our business.
We exclude amortization of intangible assets from these measures
because intangibles amortization charges do not represent what our
management and what we believe our investors consider to be costs that
support our internal operating structure and could distort the
efficiencies of that structure. We also exclude stock option expense
from these measures because stock-based compensation plans and the
critical assumptions used to calculate the expense vary dramatically
between us and our peers, which we believe makes comparisons of
long-term operating performance trends difficult for management and
investors, and could result in overstating or understating to our
investors the costs to support our internal operating structure.

    Adjusted Research and Development (R&D) Expense and Adjusted R&D
Percentage

    We use the term "adjusted R&D expense" to refer to GAAP R&D
expense, excluding amortization of intangible assets and stock option
expense. We use the related term "adjusted R&D percentage" to refer to
adjusted R&D expense as a percentage of GAAP revenue. We believe that
these non-GAAP measures, when taken together with our GAAP financial
measures, allow us and our investors to better understand and evaluate
our internal technology investments. We exclude amortization of
intangible assets from these measures because intangibles amortization
charges do not represent what our management and what we believe our
investors consider to be internal investments in R&D activities and
could distort our R&D investment level. In addition, we exclude stock
option expense from these measures because stock-based compensation
plans and the critical assumptions used to calculate the expense vary
dramatically between us and our peers, which we believe makes
comparisons of long-term operating performance trends difficult for
management and investors, and could result in overstating or
understating to our investors the amount of our internal investments
in R&D activities.

    Adjusted Operating Profit and Adjusted Operating Profit Percentage

    We use the term "adjusted operating profit" to refer to GAAP
operating profit, excluding amortization of intangible assets,
inventory fair value adjustments related to business acquisitions,
gains on the settlement of insurance claim, restructuring and lease
charges and stock option expense. Adjusted operating profit is
calculated by subtracting adjusted R&D expense and adjusted SG&A
expense from adjusted gross margin. We use the related term "adjusted
operating profit percentage" to refer to adjusted operating profit as
a percentage of GAAP revenue. We believe that these non-GAAP measures,
when taken together with our GAAP financial measures, allow us and our
investors to analyze the costs of the different components of
producing and selling our products, to better measure the performance
of our internal investments in technology and to evaluate the
long-term profitability trends of our core operations. Adjusted
operating profit also provides for easier comparisons of our
performance and profitability with prior and future periods and
relative comparisons to our peers. We believe our investors do not
consider the items that we exclude from adjusted operating profit to
be costs of producing our products, investments in technology and
production, and costs to support our internal operating structure, and
so we present this non-GAAP measure to avoid overstating or
understating to our investors the performance of our operations. In
addition, we exclude gains on the settlement of insurance claim and
restructuring and lease charges because they tends to occur due to an
acquisition, divestiture, repositioning of the business or other
unusual event that could distort the performance measures of our
internal investments and costs to support our internal operating
structure.

    Adjusted Earnings per Share

    We use the term "adjusted earnings per share" to refer to GAAP
earnings per share, excluding discontinued operations, amortization of
intangible assets, inventory fair value adjustments related to
business acquisitions, gains on settlement of insurance claim,
restructuring and lease charges and stock option expense. Adjusted
earnings per share is calculated by subtracting adjusted R&D expense,
adjusted SG&A expense, other income / expense and provision for taxes
from adjusted gross margin. We believe that this non-GAAP measure,
when taken together with our GAAP financial measures, allows us and
our investors to analyze the costs of producing and selling our
products and the performance of our internal investments in technology
and our internal operating structure, to evaluate the long-term
profitability trends of our core operations and to calculate the
underlying value of the core business on a dilutive share basis, which
is a key measure of the value of the company used by our management
and we believe used by investors as well. Adjusted earnings per share
also facilitates the overall analysis of the value of the company and
the core measure of the success of our operating business model as
compared to prior and future periods and relative comparisons to our
peers. We exclude discontinued operations, amortization of intangible
assets, inventory fair value adjustments related to business
acquisitions, gains on the settlement of insurance claim,
restructuring and lease charges and stock option expense as these
items do not represent what our management and what we believe our
investors consider to be costs of producing our products, investments
in technology and production, and costs to support our internal
operating structure, which could result in overstating or understating
to our investors the performance of our operations.

                                 ****

    The non-GAAP financial measures described above are not meant to
be considered superior to, or a substitute for, our financial
statements prepared in accordance with GAAP. There are material
limitations associated with non-GAAP financial measures because they
exclude charges that have an effect on our reported results and,
therefore, should not be relied upon as the sole financial measures to
evaluate our financial results. Management compensates and believes
that investors should compensate for these limitations by viewing the
non-GAAP financial measures in conjunction with the GAAP financial
measures. In addition, the non-GAAP financial measures included in
this earnings announcement may be different from, and therefore may
not be comparable to, similar measures used by other companies.

    Each of the non-GAAP financial measures listed above are also used
by our management to evaluate our operating performance, communicate
our financial results to our Board of Directors, benchmark our results
against our historical performance and the performance of our peers,
evaluate investment opportunities including acquisitions and
discontinued operations, and determine the bonus payments for senior
management and employees.
