BERLIN, April 13 (Reuters) - German ecommerce investor Rocket Internet reported more progress in narrowing losses at most of its leading start-ups on Friday, and said it still had plenty of cash, although it would also consider other funding options.
Rocket Internet, which had a shaky start after listing in 2014 as its start-ups racked up big losses, has seen its share price jump 60 percent in the last year after it took its biggest holdings HelloFresh and Delivery Hero public.
In a conference call with journalists, finance chief Peter Kimpel declined to comment on reports that Rocket’s furniture site Home24 and African online shopping platform Jumia are preparing potential stock market listings.
Rocket Internet reported aggregate sales rose 28 percent in 2017 to 2.64 billion euros ($3.25 billion) at its top five start-ups, while they cut their aggregate adjusted EBITDA loss to 316 million euros from 360 million in 2016.
Rocket’s shares traded down 0.2 percent at 0713 GMT.
Rocket holdings HelloFresh, Home24 and Global Fashion Group have already reported quarterly figures.
Jumia’s sales rose 22 percent to 36.5 million euros in the quarter, but its adjusted loss more than doubled to 39.4 million as it cut commissions to encourage more sellers to use its marketplace.
Rocket said it had gross cash of 2.7 billion euros, plus 0.5 billion at individual companies, as of the end of March, adding it continued to evaluate private funding and other funding alternatives for its companies.
However, Chief Executive Oliver Samwer said he did not see an immediate investment opportunities in the next one to three months, adding he continues to look for fast-growing companies. ($1 = 0.8118 euros) (Reporting by Emma Thomasson Editing by Maria Sheahan and David Evans)
