. (NSR) said its fourth-quarter profit rose slightly as a double-digit revenue gain was partly offset by higher operating expenses.
Shares fell 26% to $32.20 in after-hours trading, shortly after the results were announced, as the company's 2014 per-share earnings guidance missed expectations.
The company said that in October it submitted a request for all bidders to have an opportunity to submit additional revised proposals, along with its own revised proposal to be selected as the local number portability administrator. NeuStar said it recently was notified that its October request won't be considered.
For the year, the data and analytics provider forecast per-share earnings of $3.64 to $3.80 and revenue of $945 million to $970 million. Analysts polled by Thomson Reuters expected per-share profit of $3.82 and revenue of $968 million.
The company's board also authorized as much as $200 million in addition stock buybacks.
NeuStar reported a profit of $38.1 million, or 59 cents a share, up from $37.8 million, or 56 cents a share, a year earlier. Excluding stock-based compensation, acquisition-related costs and other items, adjusted earnings rose to 94 cents from 75 cents. Revenue increased 11% to $237.6 million.
Analysts polled by Thomson Reuters expected per-share profit of 86 cents and revenue of $233.9 million.
