The entrenched strategy of reckless capacity expansion is one of the things that Dave and others have said they are trying to change. The company may ultimately have to shed some fabs and associated headcount for that effort to better align with the realistic projections of (very slow) external customer growth.
Presently the company would have a hard time getting any other company to buy Foundry, due to the ongoing capital requirements. Every company that has considered a takeover has so far passed.
Foundry will have to get smaller to be viable, as part of Intel or as part of a takeover.
Keep in mind that only 4% of the total wafer volume is EUV, and it will take a number of years before 10nm ramps down enough for EUV to be the dominant node.
That is a big part of the high cost structure and keep in mind that there is 0% interest by external customers for 10nm, and 7nm is basically a failed node as well due to cost of being non-EUV.
Note to BK: passing on EUV for 10nm is going to drive the company into a ditch.
Other than suddenly getting a lot of 18A customers (it takes YEARS to onboard regardless of tariffs or any other incentives), the only way to really speed up the transition is to sell 7nm and 10nm fabs to Global Foundries, Samsung or some smaller fab companies.
Absent one of those two things, the next few years will be a race to insolvency, because the company can not generate enough cash flow to feed the pig. And no other company would want to take that on either, unless they too would have a plan to sell off the legacy node fabs.
