Brooks Automation Announces Preliminary Results of Tender Offer for its Common Stock

CHELMSFORD, MA, June 29, 2007 — Brooks Automation, Inc. (Nasdaq: BRKS) today announced the preliminary results of its modified “Dutch Auction” tender offer which expired at 11:59 p.m., Eastern Daylight Time, on June 28, 2007. In accordance with the terms and conditions of the tender offer, and based on the preliminary count of the depository, the Company expects to accept for purchase 6,060,000 shares of its common stock at a purchase price of approximately $18.20 per share, for a total cost of approximately $110.3 million.

Based on a preliminary count by the depository, approximately 7,400,000 common shares were properly tendered and not withdrawn at prices at or below the purchase price. In total, approximately 15 million common shares were properly tendered and not withdrawn.

The number of shares to be purchased and the purchase price per share are preliminary. Final results for the tender offer will be determined subject to confirmation by the depositary of the proper delivery of the shares validly tendered and not withdrawn. The actual number of shares to be purchased and the purchase price per share will be announced following the completion of the verification process. Payment for the shares accepted for purchase will occur promptly thereafter.

Since the offer was oversubscribed, the number of shares that Brooks will purchase from each tendering shareholder will be prorated, based upon the proration procedures described in the Offer to Purchase mailed to shareholders and certain other limited exceptions. Based upon the preliminary count, shareholders who validly deposited common shares to the Offer at a price equal to or below $18.20 per share will have approximately 80% of those shares purchased for cancellation.

The number of shares the Company expects to purchase in the tender offer represents approximately 8% of its currently outstanding common shares. In the tender offer, the Company initially offered shareholders the opportunity to tender some or all of their shares at a price not less than $16.50 per share or more than $19.00 per share, net to the seller in cash, without interest.
