Aug 10 (Reuters) - African e-commerce firm Jumia Technologies said on Wednesday it was past peak losses and would focus on promotions, marketing and cost cutting in its quest towards profitability, driving its shares up 16% despite a wider quarterly loss. Jumia is an online marketplace for vendors and food sellers, with associated services including logistics and payments. Jumia still expects a full-year adjusted EBITDA loss of $200 million-$220 million, but it reduced its full-year capital expenditure guidance to $10 million-$15 million from $15 million-$25 million. Its quarterly active consumers rose 25% to 3.4 million, while total revenue for the quarter reached $57.3 million, up 42.5%. "If they were to enter those markets, ... it would be a great validation of the attractiveness of e-commerce in Africa," he said.
