Revenue is how much you sold stuff for. Profit is how much did you make after paying for everything to run your business. They got $544M but spent $668M, so they didn’t make a profit.
It’s a bit more complicated than that. There are a lot of accounting tricks to be constantly making losses but end up cash flow positive.
I don’t work or invest in Unity so I don’t have a great understanding of their metrics but companies I worked at would constantly capitalize new projects to add expenses in the future. You can structure sales deals so a new feature is added late in the contract. That pushes revenue out, but you can collect more cash early.
If unity didn’t do share buy backs this quarter, they would have a positive cash flow. Which points to they should be a profitable company but instead are using accounting tricks to post losses to lower tax bills.
They didn’t earn $544M, they had $544M in revenue. They lost $124M but it’s all due to their decisions. They have a great operating margin in the 60s and spent all the money elsewhere.
