Chelmsford, Massachusetts August 4, 2011 — Brooks Automation, Inc. (Nasdaq: BRKS) announced financial results for the Company’s third quarter of fiscal year 2011 ended on June 30, 2011.

Revenues for the third quarter of fiscal 2011 were $186.1 million, compared to revenues of $156.8 million in the third quarter of fiscal 2010, an increase of 18.7%. Sequentially, revenues decreased 3.4% from second quarter fiscal 2011 revenues of $192.7 million. Order bookings for the third quarter of fiscal 2011 were $190.8 million, a 1.5% sequential decrease as compared to order bookings in the fiscal second quarter of $193.7 million.

Net income attributable to Brooks Automation, Inc. for the third quarter of fiscal 2011 amounted to $66.2 million, or $1.02 per diluted share. The result included the gain on sale of the contract manufacturing business which resulted in a pre-tax gain of $45.0 million with associated taxes on the gain of $2.4 million. This and other special charges and non-recurring income and their impact on comparative results are identified in the unaudited table included with this release.

Excluding special charges or non-recurring income, the adjusted net income of $23.3 million or $0.36 per diluted share compares on a sequential basis with $26.8 million or $0.41 per diluted share and improves on income of $16.9 million or $0.26 per diluted share in the third quarter of fiscal 2010. Including special charges and non-recurring income, the Net income attributable to Brooks in the second quarter of fiscal 2011 and the third quarter of fiscal 2010 was $26.6 million, or $0.41 per diluted share, and $16.6 million, or $0.26 per diluted share, respectively.

Revenues for the nine months ended June 30, 2011 were $557.2 million, a 35.5% increase over revenues of $411.3 million for the nine months ended June 30, 2010. Net income attributable to Brooks for the nine months ended June 30, 2011 was $116.3 million or $1.79 per diluted share, as compared to $34.8 million or $0.54 per diluted share for the nine months ended June 30, 2010. Excluding the impact of special charges and non-recurring income, net income increased to $73.9 million or $1.14 per diluted share for the nine months ended June 30, 2011 as compared to $25.9 million or $0.40 per diluted share, for the nine months ended June 30, 2010.

Brooks Automation Reports Third Quarter Financial Results		page two

Adjusted Earnings before Interest, Tax, Depreciation and Amortization for the third quarter of fiscal 2011 was $29.5 million, which compared to $34.1 million in the second quarter of fiscal 2011 and $22.5 million in the third quarter of fiscal 2010. A reconciliation of non-GAAP measures to the most nearly comparable GAAP measure follows the consolidated statements of operations, balance sheets and statements of cash flows included in this release. Adjusted Earnings before Interest, Tax, Deprecation and Amortization for the nine months ended June 30, 2011 was $93.5 million as compared to $45.4 million for the nine months ended June 30, 2010.

Net cash provided by operating activities for the third quarter of fiscal 2011 was $28.3 million, which together with net proceeds from the company’s M&A activities of $76.7 million and net of capital expenditures of $1.0 million resulted in an increase of total cash and marketable securities to $282.4 million at June 30, 2011. For the first nine months of the fiscal year cash from operating activities was $67.2 million and the increase in total cash and marketable securities was $139.9 million.

Steve Schwartz, Chief Executive Officer and President of Brooks stated, “We have seen a high level of uncertainty associated with our near-term revenues into semiconductor markets with significant demand adjustments from our OEM customers consistent with the public outlook they have provided. This trend had been generally negative, however our positioning into adjacent markets is cushioning Brooks from the worst of this current demand correction.”

Dr. Schwartz continued, “In the coming months we will have significant focus on the successful integration of our Nexus Biosystems and RTS Life Sciences acquisitions. The formation of Brooks Life Science Systems is intended to be a vehicle for substantial long term growth in the Life Sciences market of which our initial growth in Biobanking and Automated Sample Management Systems will be a key foundation.”

The Company additionally announced that the Board of Directors had declared a dividend of $0.08 per share payable on September 30, 2011 to stock holders of record on September 9, 2011. Future dividend declarations, as well as the record and payment dates for such dividends, are subject to the final determination of the Company’s Board of Directors.

Martin Headley, Executive Vice-President and Chief Financial Officer, observed that “The initiation of a dividend payment represents a third leg to enhancing shareholder value following the focus on higher performing components in our core business and the start of investment in a new growth platform through recent acquisitions.”

Notes on Non-GAAP Financial Measures:

The information in this press release is for: internal managerial purposes; when publicly providing guidance on future results; and as a means to evaluate period-to-period comparisons. These financial measures are used in addition to and in conjunction with results presented in accordance with GAAP and should not be relied upon to the exclusion of GAAP financial measures. Management believes these financial measures provide an additional way of viewing aspects of our operations, that, when viewed with our GAAP results and the accompanying reconciliations to the corresponding GAAP financial measures, provide a more complete understanding of our business. Management strongly encourages investors to review our financial statements and publicly-filed reports in their entirety and not rely on any single measure.

The press release includes financial measures which exclude the effects of non-recurring income and special charges such as restructuring charges and gains or losses on investments. Management believes these measures are useful to investors because it eliminates accounting charges that do not reflect Brooks’ day-to-day operations. A table reconciling income and diluted earnings per share from operations is presented below:
