The Globe and Mail reports in its Friday, Feb. 9, edition that Lightspeed Commerce's shares fell 24.4 per cent on Thursday after it said it generated $239.7-million in revenue during the third quarter ended Dec. 31, above its previously forecast range of $232-million to $237-million, and up 27 per cent from a year earlier (all figures U.S.). The Globe's Sean Silcoff writes that the market response underscores the challenges unprofitable software companies continue to have amid a continuing sector slump, as they juggle twin investor demands: to grow briskly but not lose money. For a straight second quarter, Lightspeed hit a key target: positive earnings before interest, taxes depreciation and amortization and further adjustments for items including share-based compensation and related payroll taxes. The measure, called "adjusted EBITDA," is not a recognized accounting standard, but Lightspeed has said it will achieve at least break-even results by that measure this year. Lightspeed made $3.6-million in adjusted EBITDA in the quarter, above its $2-million prediction. Its net loss was $40.2-million. Lightspeed also slightly improved its revenue forecast for the year to between $895-million and $905-million.
