Wall Street pans AT&T’s plans to spend billions to upgrade and expand its U-verse service.

Wall Street credit ratings agencies are unhappy with AT&T’s plans to increase spending on its broadband network to upgrade U-verse speeds and provide the fiber to the neighborhood service to more customers.

First, Moody’s placed AT&T’s “ratings on review for downgrade,” because AT&T’s plan to spend $22 billion to upgrade service and repurchase its own shares would throw AT&T’s debt level too high. Now Fitch Ratings has gone further, telling clients it has “downgraded” AT&T with a “negative outlook” because the phone company will spend money to provide U-verse to customers not profitable quickly enough to make the spending worthwhile.

Several Wall Street firms question the return on investment providing Internet service in rural areas where capital costs are higher. But many investment analysts are more positive about AT&T’s wireless service, which delivers substantial profits in much shorter time periods. Fitch called AT&T’s investments in LTE 4G service positive and important as Verizon Wireless continues to build and expand its own 4G LTE network.
