    Brooks Automation Reports Results for Fiscal 2004 Third Quarter Ended
                                June 30, 2004

   Company exceeds earnings guidance and delivers record-level revenues and
                                   bookings

    CHELMSFORD, Mass., July 29 /PRNewswire-FirstCall/ -- Brooks Automation,
Inc. (Nasdaq: BRKS), which delivers hardware and software systems that enable
semiconductor and other complex industries to improve manufacturing
efficiencies, today announced results for its fiscal 2004 third quarter ended
June 30, 2004.
    Revenues for the third quarter 2004 were $155.2 million, a sequential
increase of 12.5 percent from the preceding quarter revenues of $138.0
million, and an 84.7 percent increase from the third quarter 2003 revenues of
$84.0 million.  Bookings for the quarter were $155.7 million, a sequential
increase of 2 percent from the preceding quarter bookings of $152.7 million,
and an increase of 112 percent over the third quarter 2003 bookings of $73.4
million.
    The net income for the third quarter 2004 on a GAAP ("Generally Accepted
Accounting Principles") basis was $12.3 million, or $0.27 per diluted share,
ahead of guidance, compared to a net income of $6.2 million, or $0.14 per
diluted share in the immediately preceding quarter, and a net loss in the
third quarter 2003 of $36.4 million or $0.99 loss per share.  Included in GAAP
net income were restructuring charges totaling $0.9 million and amortization
of acquired intangibles totaling $0.9 million.  These charges reduced earnings
in the third quarter by $0.04 per diluted share.
    Commenting on the results of fiscal Q3, Brooks Automation chairman and
chief executive officer Robert J. Therrien said, "I am extremely proud of the
Company's performance both financially and operationally during this growth
cycle of our industry.  GAAP earnings of $0.27 per share exceeded our guidance
for the quarter.  Our ongoing earnings for the quarter were better than the
Thomson FirstCall consensus estimates which exclude the restructuring charges
and amortization of acquired intangibles.  Brooks continued to improve its
revenues and bookings from the preceding quarter, but just as importantly, we
were able to meet customer commitments while maintaining good control over
expenses and working capital.  As a result the net change in cash and
securities for the period was an increase of $11.6 million even while we
continued to ramp our business to meet demand.  Revenues of $155.2 million
exceeded the high end of our guidance of $150 million entering the quarter,
helped by the completion of some long standing contracts for our legacy AMHS
product installations.  These above-plan AMHS revenues added to top-line
growth but carried lower gross margins, impacting the progress we are making
in improving gross margin leverage.  A more balanced mix in Q4 should be more
representative of the progress we have made in improving the gross margin of
the Company.  Bookings increased to $155.7 million for the quarter, driven by
a continued stream of orders from a broad base of OEM and end user customers.
I believe that the Company is well-positioned for continued market share gains
and profitable growth through the current industry growth cycle.  Longer term,
our emphasis at Brooks is on building a sustainable business model that has
the potential to grow significantly from peak-to-peak of our industry cycles,
independent of this industry's secular peak-to-peak growth rate.  We believe
that key industry trends such as accelerating OEM outsourcing of automation
components and subsystems and increased build-out of 300mm fabs put Brooks at
the sweet spot of growth."
    Edward C. Grady, president and chief operating officer, said "Brooks is
committed to manufacturing and operational excellence as a core competency.
This capability coupled with engineering expertise and domain knowledge is
important to have in-house because of the high-mix, low-volume nature of our
business.  Our flex factory model enabled us to ramp production the past few
quarters without significant increase in fixed cost and allows us to reduce or
eliminate production bottlenecks.  We have standardized on a common
manufacturing and planning system for our production lines that helps us
manage our capacity and measure performance.  Another important area of focus
is the streamlining of supply and sourcing.  Our aggressive consolidation of
our supply chain has resulted in incremental cost savings and helped us reduce
potential bottlenecks in obtaining parts.  Many of our remaining cost
reduction initiatives, such as redesigning of products and better leveraging
of our global supply chain, should further drive gross margin improvements
over the next several quarters.  We are seeing strong operational results and
earnings leverage due to the ability of our world class team to execute our
business strategy.  It is clear that our operational performance has
contributed to significant gains in the market.  Importantly, we have gained
the confidence of customers by satisfying their requirements for quality,
cost, delivery, and need for flexibility through this period of industry
growth.  The Brooks organization remains focused on continuously improving
operational performance throughout all cycles of the industry."
    Mr. Therrien commented on Brooks' business outlook.  "The market
indicators are mixed for the next 3 to 6 months, reflecting both the continued
investment plans of the semiconductor industry for new 300mm fabs as well as
the need for some segments of the market to right-size their inventory.  We
continue to see orders and revenues staying at the current level in fiscal Q4.
Further improvements in gross margin should offset the impact of higher
variable compensation in Q4.  As a result, net income for Q4 is projected to
roughly match that of Q3.  We remain focused on what we can control at Brooks
- - building a culture of excellence and staying committed to delivering
positive results for our customers, our shareholders and our employees."

    "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 revenue and profit and loss expectations,
gross margin and operating margin expectations, our future business strategy
and market opportunities, the quality and effectiveness of our manufacturing
processes, continuing improvements in our ability to manage expenses and to
meet customer expectations and demand, level of capital expenditures and
bookings expectations in the semiconductor industry, demand for our products,
and the outlook of the general economy and the semiconductor industry.
Factors that could cause results to differ from our expectations include the
following:  our dependence on the cyclical semiconductor industry; the
possibility of future downturns in market demand for electronics; the
possibility that the upturn in market demand for electronics will not be
sustained; 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 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.
