NEW YORK, Jan 27 With only days remaining until it loses its grip over U.S. iPhone sales, AT&T Inc (T.N) warned of a "rocky" start to 2011.
AT&T's shares fell nearly 3 percent in response to a disappointing profit outlook for the year, further unnerving investors about its growth prospects once market leader Verizon Wireless launches an Apple Inc. (AAPL.O) iPhone next month.
Chief Executive Randall Stephenson, even while forecasting "healthy" customer growth, acknowledged that the new iPhone would make life tougher, at least initially.
"It may be rocky in the beginning of the year, kind of volatile, hard to predict, but we think as we work through it and the market stabilizes, we'll be able to grow through it," Stephenson said during the company's quarterly conference call in which he seldom takes part.
The company, heavily dependent on iPhone, forecast 2011 earnings per share growth in the mid-single-digit percentage range. Analysts expected growth of about 10 percent.
"I suspect they're coming to grips with the reality of the iPhone exclusivity wearing off," said Avian Securities analyst Gerard Hallaren. He described it as "a slow bleed" for AT&T.
Adding to negative sentiment, AT&T's net additions of 400,000 valuable contract customers in the fourth quarter compared poorly with almost 504,000, the average expectation from eight analysts contacted by Reuters.
AT&T's figure was also less than half the 872,000 new contract customers reported by Verizon Wireless, a venture of Verizon Communications (VZ.N) and Vodafone Group Plc (VOD.L).
"These results coming on the heels of Verizon's, really demonstrate Verizon's leadership position in the (contract customer) segment," Mizuho analyst Michael Nelson said.
AT&T's wireless profit margin was thinner than expected, too. The margin remained at 37.6 percent, in line with the third quarter, counter to AT&T's promise for an improvement.
The prospect of a Verizon iPhone has set the tone for the telecoms industry this earnings season.

But AT&T noted that it still managed to activate 4.1 million iPhones in the quarter on top of 5 million activations in the third quarter, despite widespread speculation about the Verizon Wireless iPhone's arrival.
"With all that hype going on, we sold over 9 million iPhones," Chief Financial Officer Rick Lindner told Reuters. "We've a very solid loyal customer base with the vast majority with long-standing family or business relations."
Piper Jaffray analyst Christopher Larsen also found some positive news in AT&T's addition of 442,000 customers using tablet computers, including Apple's iPad. AT&T also cited sales of tablets based on Google Inc's (GOOG.O) popular Android software.
"That's one of the things they're doing," Larsen said. "They're not just about iPhones. They're selling a lot of other devices."
Excluding unusual items, AT&T earned 55 cents per share compared with the average analyst estimate for 54 cents a share, according to Thomson Reuters I/B/E/S.
Operating revenue rose 2.1 percent to $31.36 billion. Analysts were expecting revenue of $31.47 billion.
AT&T said it sees consolidated revenue growing this year at a similar rate to its 1.4 percent growth in 2010. It said earnings per share growth would be helped by improvements in both wireless and wireline profit margins.
It forecast capital spending for the year would be in the low-to-mid $19 billion range and wireless spending increases would be offset by lower wireline capital expenses.
AT&T shares fell 86 cents or just under 3 percent to $27.87 on the New York Stock Exchange after the report. (Additional reporting by Ritsuko Ando; editing by Derek Caney, Dave Zimmerman and Gunna Dickson)
