Sunnyvale, CA - July 13, 2004 -- Juniper Networks, Inc. (NASDAQ: JNPR) today
reported its results for the quarter ending June 30, 2004.

Net revenues for the second quarter were $306.9 million, compared with $165.1
million for the same period last year, an increase of 86 percent.

GAAP net loss for the second quarter was $12.6 million or $0.02 per share,
compared with a GAAP net income of $13.6 million or $0.03 per share in the
second quarter of 2003. Non-GAAP net income was $42.7 million or $0.08 per
share, compared with non-GAAP net income of $10.3 million or $0.03 per share in
the second quarter of 2003. See the table at the bottom of the Non-GAAP

non-GAAP net income to the GAAP net loss.

Cash provided by operations was $119.0 million for the second quarter, compared
to cash provided by operations of $60.3 million for the same period last year.
Capital expenditures and depreciation during the second quarter were $12.1
million and $10.1 million, respectively.

In a separate announcement, Juniper today announced that its Board of Directors
authorized a stock repurchase program of up to $250 million.

"The key to Juniper's strong second quarter results was our simultaneous
execution," said Scott Kriens, chairman and CEO of Juniper Networks. "We met our
financial objectives, exceeded our goals for integration of the NetScreen
acquisition, expanded our partner and channel relationships, all while remaining
intensely focused on our customers and their needs for secure high performance
network solutions. As a result, our momentum and the confidence of our customers
put us in an incredible position as we enter the second half of 2004."
