NEW YORK ( TheStreet) -- AT&T ( T) beat analysts' topline forecast in its second-quarter results, released after market close, although the company's earnings dipped below consensus expectations. The telecom giant brought in revenue of $32.1 billion, up from $31.58 billion in the prior year's quarter and above Wall Street's consensus estimate of $31.8 billion. Excluding special items, however, AT&T earned 67 cents a share, up from 66 cents in the same period last year, but below the consensus estimate of 68 cents a share. AT&T's operating expenses rose to $26 billion from $24.8 billion in the second quarter of 2012. Investors were underwhelmed by the numbers, pushing AT&T's shares down 1% to $35.5 in extended trading. AT&T nonetheless cited strong growth in second-quarter wireless revenue, which 5.7% compared from a year earlier. The Apple ( AAPL) and Samsung partner also added 1.2 million new smartphone subscribers. During the second quarter, AT&T added 551,000 new postpaid wireless subscribers, its best second-quarter postpaid net adds in four years. Rival Verizon ( VZ), however, added 941,000 new postpaid subscribers when it reported its own second-quarter results last week. --Written by James Rogers in New York.
