AT&T keeps getting bigger but still is managing to execute on all cylinders. It is earning accolades from financial analysts and seeing its stock price rise (buoyed by a potential 10% dividend increase and a $10 billion stock buyback). ________________________________________ New! Watch this Network World Webcast - Optimize your WAN, save cash, and simplify your life: Case studies from the real world ________________________________________ During the last nine months, AT&T's wireline business revenue exceeded $43 billion. The last nine months' revenue for Cingular Wireless, which AT&T expects to own fully after it acquires BellSouth, exceeded $27 billion. Projecting revenue for this last calendar quarter at $16 billion for AT&T and $10 billion for Cingular results in a staggering $96 billion annual run-rate. Voice revenues (54.5%) still drive AT&T's balance sheet, but data revenue (28.5%) is growing from quarter to quarter. Look at these statistics for perspective on AT&T's stature: Its global backbone network comprises more than 535,000 fiber route-miles handling 7.6 petabytes of data traffic per business day; it hosts 30 Internet data centers on four continents, five global network operations centers and 10 global customer-support centers; and it has almost 100,000 access points in 150 countries, as well as strategic relationships with 190 carriers.
