A number of telecom equipment providers are climbing after AT&T (T) announced that it would spend about $22B annually over the next three years on capital projects. The company will increase its capital expenditures by about 15% in 2013 compared with 2012. Over the next three years, AT&T intends to spend $14B to expand its wireless and wireline broadband networks, the company added. In a note to investors earlier today, Citigroup analyst Kevin Dennean wrote that the telecom giant will spend about 18% more on capital expenditures over the next three years than research firms' average forecast. Dennean identifies Ciena (CIEN), Juniper (JNPR), Cisco (CSCO) and Adtran (ADTN) as key beneficiaries of AT&T's larger than expected spending increases. Also benefiting will be JDS Uniphase (JDSU), Finisar (FNSR) and Oclaro (OCLR), the analyst wrote. Moreover, Dennean predicts that other telecom carriers may follow AT&T's lead and exploit low costs of capital by significantly enhancing their networks. The analyst maintains Outperform ratings on Ciena, Cisco, Adtran, JDS Uniphase, Finisar, and Oclaro. He maintains a Neutral rating on Juniper. In early afternoon trading, Ciena climbed 8.50% to $14.30, Juniper added 1.08% to $17.73, Adtran rose 3.08% to $18.06 and JDS Uniphase advanced 5.97% to $11.27. However, Cisco dropped 1.60% to $17.20, Finisar lost 0.49% to $12.13 and Oclaro fell 1.86% to $1.58.
