Salesforce deal to buy Slack expected to be announced tomorrow after market close

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 to its current price. Salesforce is set to report quarterly earnings on Tuesday.

Talks between the two companies were first reported last week by The Wall Street Journal and confirmed by CNBC, sending Slack’s stock soaring 38%.

Salesforce has made several large acquisitions in recent years, including its $6.5 billion deal for MuleSoft in 2018 and $15.3 billion deal with data visualization company Tableau.
