Results

SEATTLE--(BUSINESS WIRE)--April 25, 2000--F5 Networks,
Inc. (Nasdaq:FFIV - news), the leading provider of integrated
content delivery and traffic management solutions that improve the availability and scalability of
Internet infrastructure, today announced results for the second quarter of fiscal 2000, which ended
March 31, 2000.

Second Quarter Highlights:

    Year-to-date net revenue increased 562 percent over the prior year and 23 percent sequentially
    to $23.6 million for the second quarter.
    Net income was $4.1 million, or $0.18 per diluted share, compared to a net loss of $(3.0) million
    or $(0.45) per diluted share for the second quarter of 1999.
    Cash flow from operations totaled $2.8 million in the quarter, $5.8 million year-to-date
    Announced an OEM agreement with Dell Computer to sell F5's products

``Our second quarter results demonstrate that we are on track for a solid performance in 2000,'' said
Jeffrey S. Hussey, chairman, president and chief executive officer of F5 Networks. ``We continue to
execute on our strategies of investing in technology to anticipate our customers' needs and to grow our
customer base, expanding sales and marketing efforts globally, building on and enhancing our
relationships with strategic partners, leveraging the F5 brand and evaluating strategic acquisitions.''

Net revenue for the second quarter of fiscal 2000 totaled $23.6 million, up 527 percent from $3.8
million in the prior year second quarter, and up 23 percent from the first quarter. Net revenue growth
was driven by increased sales of all of the company's products, to both new and existing customers,
and by a significant increase in service revenue and sales internationally.

Net income was $4.1 million, or $.18 per diluted share, in the second quarter of fiscal 2000 compared
to a loss of $(3.0) million, or $(0.45) per share, in the prior-year second quarter. For the fiscal year to
date, net revenue totaled $42.8 million, up 562 percent from the first six months of fiscal 1999. Net
income for the first six months of fiscal 2000 totaled $8.4 million, or $0.36 per diluted share, compared
to $(5.2) million, or $(0.82) per diluted share in the prior-year same period.

``Sales growth momentum and strong margins have enabled F5 to sustain profitability despite a
continuing ramp-up in infrastructure to support our growth,'' added Mr. Hussey. ``We expect that F5
will deliver sequential quarterly sales growth in the low to mid teens, and continue to post profits and
positive cash flow in the second half of fiscal 2000.''

On April 5, 2000, F5 announced a major OEM agreement with server manufacturer Dell Computer to
bring to market F5 Networks' suite of products, commencing with the Company's BIG-IP software, on
Dell's PowerApp appliance server. This appliance server product will be targeted for service providers,
dot-coms, brick-to-click businesses and other organizations building out their Internet infrastructure.

During the second quarter, F5 announced that Carlton G. Amdahl was named Chief Technical Officer.
Mr. Amdahl brings more than 20 years of experience as a senior executive and consultant in the
computer and networking industry and will be instrumental in driving F5's technology to the next level.
