Salesforce (CRM) - Get Report snapped up Tableau (DATA) - Get Report , a maker of data analytics and visualization software, in a deal announced on Monday, the biggest in Salesforce's history.

The $15.7 billion, all-stock transaction was heralded by the CEOs of both firms as a match made in heaven as Salesforce deepens its reach into data analytics. Salesforce shares were down 4.7% on the news, while shares of Tableau surged 34.6%.

"It's hard to get the stars to align; we were fortunate that we got there," said Salesforce co-CEO Marc Benioff on a call with investors on Monday morning, in response to a question about why now was the right time to seal the deal. "When I talk to some of our largest customers, we're talking about Salesforce, then they start talking about how they're using Tableau. [I thought] wow, if this was more deeply integrated as one movement, we could satisfy a great customer need."

Here are three takeaways from Salesforce's investor call today discussing the purchase of Tableau, a company that Benioff dubbed a "brother from another mother."

1. Think Mulesoft

Benioff and Salesforce's chief product officer, Bret Taylor, likened the acquisition to that of Mulesoft, which Salesforce bought in 2018 in a deal worth about $6.5 billion. The executives pointed out that much like Mulesoft, Tableau's software draws data from multiple sources: Amazon (AMZN) - Get Report , Microsoft (MSFT) - Get Report , Workday (WDAY) - Get Report  and ServiceNow (NOW) - Get Report , among others. Benioff said that Salesforce doesn't get "draconian" in cutting off such data pipelines: "We always maintain a beginners mind...we've not only maintained the Mulesoft acquisition, we've added to it."

2. A 'Broad Brush' 

Tableau has 86,000 customers, which include big names like Verizon

(VZ) - Get Report

, Charles Schwab

(SCHW) - Get Report

and Netflix

(NFLX) - Get Report

. The deal, which is set to close in the fiscal third quarter, will add between $350 million and $400 million to Salesforce's overall top line next year, Salesforce said in a press release. For evidence of the breadth of Tableau's customer touch points, calling it a "broad brush," Benioff urged investors to check out Tableau's

3. Earnings Will Dip, With Better Days Ahead

Salesforce lowered its profit forecast for fiscal 2020 owing to the deal, estimating a decrease of 37 to 39 cents non-GAAP diluted EPS in fiscal 2020, resulting in profits on $2.51 to $2.53. However, on the call with investors, Salesforce executives offered reassurance that the company is committed to growing profits over time.
