Exhibit 99.1 FOR IMMEDIATE RELEASE CONTACT: Investor Relations John Eldridge (206) 272-6571 j.eldridge@f5.com Public Relations Alane Moran (206) 272-6850 a.moran@f5.com F5 Networks Announces Fiscal Third Quarter Results 16 percent operating margin on record quarterly revenue, up 52 percent year over year SEATTLE, WA -- JULY 21, 2004 -- F5 Networks today announced net income of $7.4 million ($0.20 per diluted share) on record revenue of $44.2 million for the third quarter of fiscal 2004, up from $6.0 million ($0.16 per diluted share) on revenue of $40.6 million in the second quarter. In the third quarter of fiscal 2003 the company reported net income of $1.4 million ($0.05 per diluted share) on revenue of $29.2 million. F5 president and chief executive officer John McAdam said sales in North America rebounded during the quarter and combined with strong sales in Europe and Asia Pacific to boost overall revenue 9 percent sequentially and 52 percent year over year. Strength in North America was led by product revenue, which grew 32 percent sequentially and contributed to 24 percent sequential growth of North American product and service revenue combined. As expected, Japan revenue was down sequentially following exceptionally strong sales in the prior quarter and reflecting the seasonality that typically characterizes the first quarter of Japan's fiscal year. McAdam said sales of the company's FirePass SSL VPN products also grew during the third quarter. FirePass revenue of $3.8 million was up from $2.7 million in the prior quarter, pushing revenue for the first three quarters of fiscal 2004 to $8.0 million. Steady growth of FirePass sales since the technology was acquired from uRoam in July 2003 is reflected in a recent Infonentics report which ranked FirePass second in global SSL VPN market share. In line with management's guidance, the company did not report any revenue from its newest security offering, TrafficShield, acquired with the purchase of MagniFire on May 31 of this year. McAdam said the company will continue to focus on training and integration during the current quarter, ending September 30, and expects to generate its first material revenue from TrafficShield in the first quarter of fiscal 2005, with a target of $8 to $12 million for the year. Even with the additional operating expenses resulting from the acquisition of MagniFire, the company's revenue growth enabled it to realize further improvements in its operating margin, which increased to 16 percent from 14 percent in the prior quarter. In addition, the company continued to strengthen its balance sheet, with days sales outstanding (DSO) of 40 days, contributing to positive cash flow of $10.6 million from operations. Following $26.9 million in cash payments related to the purchase of MagniFire, the company had $210 million in cash and investments at June 30. With the launch of its new traffic management products -- code-named "Buffalo Jump" -- scheduled for early September, McAdam said he is confident the new products will have a positive impact on the company's core business and will help drive solid revenue growth in fiscal 2005. For the fourth quarter of fiscal 2004, ending September 30, he said management believes the company will continue to grow sequentially and has set a target range of $45 million to $47 million in revenue. Following F5's strong performance during the past three quarters, management expects to begin recording additional U.S. income taxes and expects to reverse the valuation allowance on the company's U.S. deferred tax assets, resulting in an estimated net tax benefit of approximately $5.7 to $6.1 million in the fourth quarter. The estimated net tax benefit includes U.S. federal, state and international taxes. Earnings calculated in a manner consistent with prior quarters are expected to be $0.20 to $0.22 per share. Earnings per share including tax adjustments are expected to be $0.37 to $0.39 per share for the fourth quarter. A reconciliation of the difference between expected earnings before and after the tax adjustment is shown in the following table: RECONCILIATION OF EXPECTED FOURTH QUARTER EARNINGS Low High --- ---- Income before income taxes $ 7,800 $ 8,800 Provision for international and state taxes (400) (400) -------- -------- Net income after international and state taxes $ 7,400 $ 8,400 Net U.S. tax benefit 6,500 6,100 -------- -------- Net income after tax $ 13,900 $ 14,500 Net income after international and state taxes per share-diluted $ 0.20 $ 0.22 Net income after tax-diluted $ 0.37 $ 0.39 Weighted average shares-diluted 37,500 37,500 ABOUT F5 NETWORKS F5 enables organizations to successfully deliver business-critical applications and gives them the greatest level of agility to stay ahead of growing business demands.
