<p>Profit at EarthLink Inc., the Internet service provider, more than tripled in the fourth quarter, but revenue fell as subscribers moved to high-speed services.</p><p>The Atlanta-based company Tuesday posted net income of $35.6 million, or 23 cents a share, for the quarter, compared with $10.7 million, or 7 cents a share, a year earlier.</p><p>Earnings were helped by improved efficiencies and lower telecommunications costs, the company said.</p><p>Results for the latest quarter include a reversal of previous estimates for closing down a number of customer contact centers by $597,000. EarthLink closed a number of these facilities in 2003 and 2004 in order to improve efficiency and cut costs.</p><p>The average estimate of analysts surveyed by Thomson First Call was for fourth-quarter earnings, excluding items, of 22 cents a share.</p><p>Revenue slipped 3 percent in the quarter to $338.1 million from $348.6 million. Revenue from dial-up access and Web hosting services fell while revenue from broadband access and from advertising and other services rose.</p><p>Analysts were on average expecting a smaller revenue decline in the latest quarter, to $344.7 million.</p><p>In morning trading, shares of EarthLink fell 88 cents, or 8.6 percent, to $9.40 on the Nasdaq Stock Market.</p><p>EarthLink had 5.4 million total subscribers at the end of the quarter, up 3.5 percent from the same time a year ago.
