Roblox is the largest game in the world with over 380 million monthly users, but despite its massive scale and growth, the company is unprofitable due to high costs, including App Store fees, developer revenue shares, and infrastructure expenses. Roblox's revenue has grown significantly, but its losses have increased even more, with a -38% profit margin over the last four quarters. The company's costs are largely outside of its control, and its R&D investments are enormous, taking up 44% of revenues. Despite being unprofitable, Roblox has been cash-positive for at least twenty-four quarters, with operating cash flow of $650MM over the last twelve months.
