Cisco's revenue for fiscal year 2001 (ending July 28) was $22.29 billion, up 18% year over year, announced on August 7, 2001; by that time the dot-com bubble had already burst and the stock price had plunged.
In late March 2000, Cisco's market capitalization exceeded $500 billion, briefly surpassing Microsoft to become the world's most valuable company; the bubble then burst, and its market cap shrank by about $431 billion.
Cisco's revenue at the peak of the internet bubble in 2000 stood at $19 billion.
After the dot-com bubble burst, Cisco's stock price fell from $79 to $9.5 within two years, a cumulative decline of about 88%.
