AT&T reached a key milestone in the third quarter. Gains from the company’s next-generation fiber network offset losses from its legacy non-fiber footprint, generating net gains for the consumer broadband business. Excluding DSL and AT&T’s nascent fixed-wireless access service, the company eked out a net consumer broadband gain of 15,000, including fiber gains of 296,000. That propelled AT&T’s broadband revenues almost 10% higher, lifted by a nearly 27% gain in consumer fiber revenue. The company raises its full-year broadband revenue growth outlook to at least 7%, up from at least 5%.
