Everyone is seeing this as negative and a warning sign for DO... but they're an 8 year old privately owned company that has raised over $300m. The last time they obtained funding was a 130m credit line in 2016. It's been 4 years since then... and if they're still losing money, they likely need to either make this profitable, or they're going to need to raise more money.
If they're close to being profitable (likely given their past fund raising, and how long its been), why would they want to sell more of their business?
They may also want to finally go public. 8 years is a long time to wait for a return. And it seems to me the stock market is tired of these unprofitable unicorns doing IPOs (at the moment anyway).
