Like most growth-phase startups from SV, Doordash are not profitable at the moment and have no profit to speak of with an EPS of _negative_ $2.41. Please correct your "$700m in gross profit a quarter" to "$1.7b in revenue a quarter" or "$296m in net loss a quarter" [1].
Doordash is making something like $700m in gross profit a quarter.
Just remember this when a company calls you a family.
