Rocket Internet posted a much higher profit in the first quarter than a year earlier. The German start-up investor benefited from upgrades of companies in which it had interests. Earnings in the first quarter increased by 86 percent to 139 million euros. The African web store Jumia, for example, which went to the New York stock exchange in April, contributed to the higher result, as did the fashion platform Global Fashion Group. In the first quarter, Rocket Internet also had an interest in the deliverer of fresh packages HelloFresh. These shares have since been disposed of.
