not a public company.

You're reading the chart correctly for revenue but misinterpreting that revenue is not net-income. Twitter loses an average of $500M a year after all that revenue+costs which only makes his 44B purchase all the more perplexing. He far overpaid for a historically money losing venture, and sure if he can start to make it profitable, which happened twice in twit-history for an at best $1.5B that year .. that's a long 30yr/break even
