Deirdre Bosa joins 'Closing Bell' to report Salesforce has bought Slack. For access to live and exclusive video from CNBC subscribe to CNBC PRO: https://cnb.cx/2NGeIvi Salesforce’s deal to buy Slack is expected to be announced Tuesday after markets close, sources told CNBC’s David Faber. The deal is expected to be about half cash and half stock, the sources said, and will price Slack at a premium. Salesforce is set to report quarterly earnings on Tuesday. Slack’s market cap was more than $24 billion as of Monday morning. Shares of Slack rose about 4% Monday on the news. Salesforce shares were down more than 3%. Talks between the two companies were first reported last week by The Wall Street Journal and confirmed by CNBC, sending Slack’s stock soaring nearly 38%. Salesforce has made several large acquisitions in recent years, including its $6.5 billion deal for MuleSoft in 2018 and its $15.3 billion deal with data visualization company Tableau. The deal with Slack could become one of the largest in the software sector. IBM bought Red Hat for $34 billion in 2019 and Microsoft purchased LinkedIn for $27 billion in 2016. It could also make Slack a more formidable competitor to Microsoft’s Teams communication product. Slack filed a complaint against Microsoft with the European Commission this summer, alleging it abused its dominant market position to eliminate competition for Teams. Microsoft has said Teams has benefited during the pandemic from videoconferencing capabilities that Slack lacks. » Subscribe to CNBC TV: https://cnb.cx/SubscribeCNBCtelevision » Subscribe to CNBC: https://cnb.cx/SubscribeCNBC » Subscribe to CNBC Classic: https://cnb.cx/SubscribeCNBCclassic Turn to CNBC TV for the latest stock market news and analysis.
