Updated from Jan. 27MicroStrategy ( MSTR) surged 15% Friday morning after blowing out fourth-quarter estimates. For its quarter ended Dec. 31, the McLean, Va., business-process software maker earned $24.5 million, or $1.43 a share, up from the year-ago continuing operations profit of $17.5 million, or 98 cents a share. Revenue jumped to $71.6 million from $51.7 million a year earlier. The numbers blew the Wall Street consensus estimates out of the water. Analysts surveyed by Thomson First Call had projected an 88-cent profit on sales of $61 million. "MicroStrategy delivered another strong quarter, with record revenues, excellent operating margins, and outstanding license revenue growth," said CEO Michael Saylor. "With the scheduled release next week of MicroStrategy 8, we believe we are well positioned for another solid year in 2005." The company said it wouldn't provide quarterly guidance in the future. "The Company believes that it is in the best interests of shareholders to avoid engaging in predictions of short-term financial performance, which are inherently uncertain," MicroStrategy said. "We believe that this will allow the management team to more effectively run operations and build long-term shareholder value." After rising 5% in regular trading Thursday, MicroStrategy jumped $10.04 to $75.05 in premarket action.
