Exhibit 99.1

 Brooks Automation Reports Results for Fiscal 3rd Quarter Ended June 30, 2003



    CHELMSFORD, Mass., July 23 /PRNewswire-FirstCall/ -- Brooks Automation,

Inc. (Nasdaq: BRKS), which delivers total automation for semiconductor

manufacturing and other industries, today announced results for the fiscal

third quarter ended June 30, 2003.

    Revenues for the third quarter were $84.0 million, a 9.6 percent

sequential decline from the preceding quarter revenues of $92.9 million.

Bookings for the quarter were $73.4 million, a sequential decline of 14.4

percent from the preceding quarter bookings of $85.7 million.  The company had

estimated in its second quarter earnings report on April, 24, 2003 that in the

third quarter both revenues and bookings would decline in the range of 10 to

15 percent from second quarter results.

    The net loss for the third quarter on a GAAP ("Generally Accepted

Accounting Principles") basis was $36.4 million, or $0.99 per share, compared

to a net loss on the same basis of $28.8 million, or $0.79 per share in the

immediately preceding quarter.  The GAAP loss included a restructuring charge

of $20.7 million consisting of previously anticipated items of $7.0 million

for severance and $3.2 million for divestiture of the company's Swiss

subsidiary as well as an additional charge of $10.5 million taken after re-

evaluation of lease obligations.

    The net loss for the third quarter on a "pro forma" basis, defined as net

loss before amortization of acquired intangible assets and other acquisition

and disposition related charges, net of income taxes, was $10.9 million or

$0.29 per share, compared to the preceding quarter pro forma loss of $12.7

million or $0.34 per share, and better than the guidance of $0.35 to $0.40

loss per share.  It has been the practice of Brooks and of many other

companies as well to report pro forma financial results since management

believes that presenting the operating results before taking into account such

charges provides useful information to aid in understanding ongoing, recurring

operations.  As in previous earnings reports, a reconciliation of GAAP to pro

forma losses for the quarter is included in the attached exhibits.

    The net cash balance at the end of the third quarter was $209.6 million,

including cash, cash equivalents, short-term and long-term marketable

securities, compared to a balance of $212.9 million in the immediately

preceding quarter.

    Robert J. Therrien, chairman and chief executive officer of Brooks

Automation, said: "The company continued to make good progress during the June

quarter in achieving near term objectives for restructuring and managing the

cash flow.  The pro forma operating expenses for the third quarter decreased

to $37.0 million, a $4.2 million reduction from the preceding quarter, as we

again realized the benefits of our cost reduction efforts.  The decline in the

company's cash for the quarter was only $3 million despite significant cash

expenditures of $11 million related to restructuring and $4 million for a

semi-annual interest payment.  We were able to achieve this by continuing to

focus on reducing our working capital.  Since finishing the December 2002

quarter with a cash balance of $215 million, the decline in cash for the March

and June quarters combined was less than $6 million.  We will complete

essentially all the workforce reductions as well as the facilities

consolidations by the end of the September quarter, leaving us with fewer than

2,000 employees worldwide and 3 main manufacturing sites -- down from 3,300

employees and 14 sites one year ago -- as we drive towards our goal of

reaching operating profitability by the end of the calendar year.  We continue

to leverage our world class manufacturing capability as a competitive

advantage for the company.  As a result, Brooks has successfully positioned

itself as a leading provider of systems and custom manufacturing for its OEM

customers, who are increasingly outsourcing their automation."

    Mr. Therrien reviewed some of the highlights of the third quarter:

"Brooks introduced a number of new and enhanced products at SEMICON West

earlier this month, including the OneFab(TM) AMHS (automated material handling

system).  We believe this new system is the most advanced fourth generation

AMHS available today and when combined with industry-leading factory

management and logistics software from Brooks, provides the most complete and

robust factory automation solution for 300mm semiconductor manufacturers.  The

introduction of OneFab significantly improves Brooks' competitive position in

several AMHS opportunities in the second half of this year.  We hope to

sustain the momentum from the excitement and interest generated by the recent

launches of products such as the OneFab AMHS, the new iReticles(TM) software

for managing critical reticle data, the enhanced equipment front end module

FabExpress(TM) with high throughput 5-axis robot and industry-leading

FixLoad(TM) loadport, the Particle Detection System for 100 percent inspection

of reticles, the CleanFlow(TM) fan filter unit for mini-environments and a

number of other offerings.  The new flow of products and technology is

essential for the company to maintain its number one position in semiconductor

automation, as most recently reported by Dataquest in April 2003."

    Mr. Therrien commented on Brooks' business environment.  "Even though

visibility is still limited, we have reason to believe that bookings have

bottomed in the June quarter and are likely to increase by as much as 10 to 15

percent in the next quarter as a number of semiconductor fabs begin investing

in capital equipment.  We expect revenues for the September quarter to be down

3 to 5 percent sequentially from the June quarter based on the lower bookings

number in the preceding quarter.  The GAAP loss for the September quarter is

estimated to be in the range of $0.45 to $0.50 per share and pro forma loss to

be in a range of $0.24 to $0.29 per share.  While there are signs of a

recovery for the semiconductor device sector in the second half of the year,

capital equipment spending will likely lag the chip recovery and therefore we

remain conservative in our planning and are staying focused on improving the

operating leverage of the company and managing our cash for the next quarter."

    Pro Forma Results

    In addition to disclosing results that are determined in accordance with

Generally Accepted Accounting Principles (GAAP), Brooks also discloses pro

forma, or "non-GAAP", results of operations.  These pro forma results are

comprised of net income or net loss before the amortization of acquired

intangible assets and other acquisition and disposition related charges, net

of income taxes.  Pro forma results are provided as a complement to the

results provided in accordance with GAAP on the basis of management's belief

that presenting the Company's operating results before taking such charges

into account provides useful information to aid in understanding ongoing,

recurring operations.

    "Safe Harbor" Statement under the Private Securities Litigation Reform Act

of 1995:

    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 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, future

level and sufficiency of our cash position, our future business strategy and

market opportunities, improvements in our business, our restructuring and cost

reduction activities, our integration of acquired businesses, demand for our

products, bookings, backlog and design-ins and the general economic outlook.

Factors that could cause results to differ from our expectations include the

following:  our dependence on the cyclical semiconductor industry; the

possibility of further or future downturns in market demand for electronics

(including especially the market for semiconductor products); further downturn

in the economy of the United States and other countries brought about by the

war in the Iraq or political tensions arising between Western nations and

North Korea; the highly competitive nature and rapid technological change that

characterizes the industries in which we compete; decisions by customers to

cancel or defer orders that previously had been accepted; the fact that

certain of the company's orders are non-binding; the timing and effectiveness

of restructuring, cost-cutting and expense control measures, including

activities such as facility consolidations and staffing reductions; the

possibility of intense price competition and the possible resulting need to

lower our prices to our customers and thereby possibly our revenue; the effect

of being required to account for stock options as an expense; our ability to

manage the effects of past or future acquisitions or divestitures, including

the  need to integrate acquired businesses successfully; our ability to

protect our intellectual property; the possibility that the value of certain

acquired assets or businesses may have to be written down in light of

prevailing market conditions; the impact of the outbreak of SARS in various

parts of the world; 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 there can be 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.
