SAP's stock climbed 6% in premarket trading in New York after the company reported strong revenue growth in its cloud business. The company's current cloud backlog grew 26% on a constant-currency basis to EUR22.93 billion in the second quarter, above analysts' forecasts of 24%. SAP cut its outlook for the year, citing a EUR100 million impact from the acquisition of data platforms Prior Labs and Dremio, and trimmed its guidance for non-IFRS operating profit. CEO Christian Klein joined The Opening Trade to talk with Bloomberg's Anna Edwards and Guy Johnson.
