Salesforce's $6.5 billion acquisition of MuleSoft was the most expensive cloud software deal in history, according to some analysts, and could raise the price for future transactions.

According to a report on Wednesday from analysts at JMP Securities, the purchase price implies an enterprise value to revenue multiple of 15.8 for 2018 and 11.9 for 2019. That tops a multiple of 9.1 that SAP paid for Concur in 2014 and is more than twice the median multiple for cloud software companies of 5.3 dating back to at least 2012.
