I found this on Cisco's site.
Kinda goes with what Suresh was saying about there tier-one USA customer. Bold is mine
Cisco has continued to be one of the world’s largest and most successful networking companies. The company's growth of its product and services portfolio is primarily based on strong outside acquisitions to help Cisco go after the cloud and software market. Net income: : US$110 million (2018)
$50 Billion a year in revenue but it says only $110 million net income, must have a pretty good accountant.
