         BROOKS AUTOMATION REPORTS RESULTS FOR FISCAL 2005 FIRST QUARTER
                             ENDED DECEMBER 31, 2004

    CHELMSFORD, Mass., Feb. 1 /PRNewswire-FirstCall/ -- Brooks Automation,
Inc. (Nasdaq: BRKS), which develops and produces hardware, software and
systems that enable manufacturing efficiencies for the semiconductor and other
complex manufacturing industries, today announced results for its fiscal 2005
first quarter ended December 31, 2004.

    Revenues for the first quarter of fiscal 2005 were $117.8 million, a 42.8
percent increase from $82.5 million in the same quarter a year ago and a 28.2
percent sequential decline from the preceding quarter revenues of $164.0
million. New orders during the quarter were $101.7 million.

    Net income for the first quarter of fiscal 2005 on a GAAP ("Generally
Accepted Accounting Principles") basis was a loss of $0.9 million, which
included a charge of $2.7 million for restructuring, $0.9 million for
amortization of acquired intangible assets, and $0.5 million write-off of
inventory from the Life Sciences division. The GAAP loss per share of $0.02 per
share was within the guidance provided by management in the preceding quarter's
conference call. The first quarter 2005 GAAP net income compares to a net loss
in the first quarter 2004 of $8.9 million or $0.23 loss per share on the same
basis.

    Edward C. Grady, president and chief executive officer of Brooks Automation,
said "As expected, our revenues were down from the preceding quarter's record
high level as the industry adjusted to fluctuating supply and demand, but our
results show that we continue to react quickly to market conditions and manage
our expenses effectively. Many industry watchers have anticipated that the
weakening end market demand in the latter part of 2004 and heading into 2005
would cause a slowdown in our sector. Historically, inflection points in the
industry cycles have had a magnified effect on Brooks' OEM business over a short
term period of one to two quarters before our business stabilizes. We continue
to make good progress with our primary target markets in tool automation and
factory automation software. An industry slowdown is the best time to capture
design-in wins with OEMs, and we are involved in what we believe is the highest
level of new opportunities in Company history, and the most ever with tier one
OEM customers. Software bookings were again strong in the quarter, driven
primarily by the semiconductor and FPD markets. We have recently announced
several new solutions as part of our Real Time Enterprise initiative that are
attracting interest in their target markets. These new offerings include a
comprehensive manufacturing RFID solution for discrete industries, our Lean
Manufacturing solution for the Aerospace and Defense industry, and an eDHR
(electronic device history record) solution for track-and-trace requirements.
Our software division is planning a number of new solution launches in 2005 that
we expect will further expand our served available market."



    "Looking forward, we expect to see a slight improvement next quarter,"
continued Mr. Grady. "Revenues for Brooks should be flat to up 5 percent in the
March quarter compared to the December quarter, and bookings should increase
approximately 5 to 10 percent sequentially. This guidance reflects near term
recovery in our OEM tool automation segment but does not suggest that the rest
of the industry will be up. We are proactively managing our business during this
period of industry softness and are taking more restructuring actions in the
March quarter to continue our emphasis on cost control. The earnings per share
on a GAAP basis for the March quarter are anticipated to be in the range of a
loss of $0.05 per share to breakeven. We expect restructuring and other charges
to impact EPS by approximately $0.10 per share. We remain focused on managing
our business through all cycles of the semiconductor industry to deliver value
to our customers, shareholders and employees."

    Q1 Fiscal 2005 Highlights
     * Captured 13 new design-in wins at OEM customers in Q1.

       Taiwanese DRAM manufacturers and one new Japanese customer for their
       300mm fabs.
     * Won new order for Advance Productivity Family (APF) Suite software from a
       major high tech industry customer for its magnetic head manufacturing
       facility, after detailed ROI analysis showing cycle time variability
       improvement, through-put optimization and improved equipment utilization.
     * Announced comprehensive RFID solution for discrete manufacturers; Lean
       Manufacturing solution for Aerospace and Defense; and tracking and
       traceability solution for eDHR requirements especially in the medical
       device manufacturing industry.
     * Announced partnership with AssurX to joint develop, market and deliver
       software solutions such as eDHR for enterprise quality tracking, as well
       as membership in EPCglobal, which develops and oversees commercial and
       technical standards such as for electronic product code (EPC) technology

    "Safe Harbor" Statement under Section 21E of the Securities Exchange Act
of 1934:
    Some statements in this release are forward-looking statements made under
Section 21E of the Securities Exchange Act of 1934. These statements are neither
promises nor guarantees but involve risks and uncertainties, both known and
unknown, that could cause Brooks' financial and business results to differ
materially from our expectations. They are based on the facts known to
management at the time they are made. These forward-looking statements include
statements regarding our bookings, revenues, and profit and loss expectations,
gross margin and operating margin expectations, expected restructuring charges,
our future business strategy and market opportunities, level of capital
expenditures and bookings expectations in the semiconductor and discrete
manufacturing industries, demand for our products, and the outlook of the
semiconductor and discrete manufacturing industries. Factors that could cause
results to differ from our expectations include the following: our dependence on
the cyclical semiconductor industry; the possibility of downturns in market
demand for electronics; our possible inability to meet increased demand for our
products due to difficulties in obtaining components and materials from our
suppliers in required quantities and of required quality; our ability to
continue to effectively implement our flexible manufacturing model and our
supply chain consolidation; the highly competitive nature and rapid
technological change that characterizes the



industries in which we compete; decisions by customers to accelerate delivery
under or to cancel or defer orders that previously had been accepted; decisions
by customers to reject the products we ship to them; the possibility that we may
not be able to fulfill customer orders within a period of time acceptable to
them; the acceptance of our software products and services in industries outside
of the semiconductor industry; the fact that design-in wins do not necessarily
translate to significant revenue; the timing and effectiveness of restructuring,
cost-cutting and expense control measures; intense price competition; possible
disputes concerning intellectual property; continuing uncertainties in global
political and economic conditions, especially arising out of conflict in the
Middle East; and other factors and other risks that we have described in our
filings with the Securities and Exchange Commission, including but not limited
to Brooks' Annual Report on Form 10-K and our quarterly reports on Form 10-Q. As
a result we can provide no assurance that our future results will not be
materially different from those projected. Brooks expressly disclaims any
obligation or undertaking to release publicly any updates or revisions to any
such statement to reflect any change in our expectations or any change in
events, conditions or circumstances on which any such statement is based. Brooks
undertakes no obligation to update the information contained in this press
release.
