“Gross profit” is a meaningless number in this context. Their net income was $15.5B. If you do the same math to try to determine profit per location, ($15.5B/10500) it’s about $1.48M. Not bad, but still about 90% lower than your estimate.
Since I was already estimating seemingly random profit ratios, I also looked at their profit per employee, which came out to $7380/person ($15.5B/2.1M employees).
Unfortunately these numbers are also inclusive of, for example, Walmart’s e-commerce program, so calculating the profit per location doesn’t indicate anything meaningful to me, though I’m morbidly curious about what insights you are hoping to get from it?
ACKTUALLY, whether or not you can get fired is a state issue, and some states such as California provide statutory protection for employees who use cannabis. It’s true that there are some states where you can get in trouble, but the federal laws are not being enforced by the Biden administration, who has given the green light on cannabis consumption and rescheduling, so there’s really no single answer that applies to the whole United States, and your mileage may vary.
