"Expenses" and "revenue" are rather fuzzy concepts in this case: Intel's foundry business (as in, Intel manufacturing chips for somebody else) is still mostly aspirational; almost all of the chips they make are Intel chips, and there's a lot of wiggle room for how much of the revenue from selling Intel-branded chips gets assigned to their foundry business vs eg. the Client Computing Group or the Data Center and AI division. If they were reporting Intel Foundry revenue only from outside foundry customers (they're not), then Intel Foundry would never be able to come close to profitability.
