STOCKHOLM ( TheStreet) -- Ericsson ( ERIC), the Swedish telecommunications maker, posted an increase in third-quarter earnings on strong demand for mobile broadband and increased services revenue. Profit rose to 3.8 billion kronor ($575.8 million) from 3.6 billion kronor a year earlier. Sales jumped 17% to 55.5 billion kronor. "Our performance year-to-date reaffirms our indications of a strengthened global market share," said Ericsson CEO Hans Vestberg, in a statement Thursday. However, Vestberg said gross margins in the quarter fell to 35% from 39% on a "higher proportion of coverage projects along with accelerating network modernization projects in Europe." Ericsson said effects from the March earthquake and tsunami in Japan on the company's supply chain have been eliminated and lead times are back to normal. But "with economic uncertainties in parts of the world, we cannot exclude somewhat more cautious short-term operator spending," the company said. -- Written by Joseph Woelfel >To contact the writer of this article, click here: Joseph Woelfel >To submit a news tip, send an email to: email@example.com.
