An investor in Tableau Software Inc. has accused the business analytics firm’s board of hiding the affect that competition from Amazon, IBM and Microsoft would have on the company’s bottom line.

The lawsuit, filed Tuesday in Delaware federal court, comes just over a month after a Manhattan judge terminated the company’s motion to dismiss a securities class action stemming from a nearly 50 percent drop in Tableau’s stock in 2016 after the market caught wind of the toll new competition was taking on its business.
