Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On June 10, 2005, Brocade Communications Systems, Inc. (the “Company”) received a written Staff Determination notice from the Nasdaq Stock Market stating the Company is not in compliance with Nasdaq’s Marketplace Rule 4310(c)(14) because the Registrant has not timely filed its Report on Form 10-Q for the fiscal quarter ended April 30, 2005. Therefore, the Company’s securities are subject to delisting. A copy of the press release issued on June 13, 2005 announcing the receipt of the notice is attached hereto as Exhibit 99.1.

The Company plans to appeal this determination and to request a hearing on such appeal. Requesting a hearing will stay the delisting until the hearing panel has rendered a decision. There can be no assurances that the hearing panel will grant the Company’s request for continued listing.
