As previously announced by Juniper Networks, Inc. (the “Company”), the Audit Committee of the Board of Directors has been conducting an investigation into the Company's stock option practices and has reached a preliminary conclusion that the actual measurement dates for financial accounting purposes of certain stock option grants issued in the past differ from the recorded grant dates of such awards. On August 9, 2006, upon the recommendation of management and the Audit Committee, the Board of Directors of the Company concluded that financial statements and all earnings press releases and similar communications issued by the Company relating to periods beginning on or after January 1, 2003 should no longer be relied upon, including the Company's financial statements for fiscal years 2003, 2004 and 2005, the interim periods contained therein, and the quarter ended March 31, 2006. The Company intends to restate its financial statements as a result of the independent investigation as necessary, but has not determined the amount of such charges, the resulting tax and accounting impact, or which specific periods require restatement. The independent investigation is ongoing, and there can be no assurance that additional adjustments will not be required. As a result of the ongoing investigation, the Company was unable to prepare restated financials prior to the prescribed due date of August 9, 2006 for the Form 10-Q for the quarter ended June 30, 2006. Consequently, the Company is unable to file its Quarterly Report on Form 10-Q for the quarter ended June 30, 2006 within the prescribed period without unreasonable effort or expense.
