Vodafone’s German unit may see a “slight dip” in sales in its next fiscal year, its chief executive told Dow Jones Newswires. Vodafone Germany is currently presenting itself as an integrated telecoms company for the first time at this year’s CeBIT show in Germany. Last year Vodafone bought the remaining 26.4 percent stake in DSL provider Arcor it didn’t already own, for EUR474 million.
