The current effort should enable the company to create the option of spinning off (an at least marginally profitable) IFS and/or selling what then would be more profitable Product groups.
Strategy seems to be to clean up the leftover efforts from when the company dominated client and server markets, and become a more focused conglomerate.
Then the option to stop being a conglomerate becomes a real thing. IFS losses make it difficult to get a decent valuation if it were spun off or sold now, and IFS is also not yet set up to operate under industry standard design rules and PDK (until 18A-P), so no other foundry would have much interest in IFS at the moment.
Because of the ongoing IFS losses, the company needs ProdCo profits to remain solvent, so getting IFS profitable is Job #1. Absent external customer growth, the only other option is to reduce (labor) cost, so expect outsourcing in the near future.
Cash burn can also be reduced by selling off the older fabs or some entire sites, and I expect something to happen on that front as well. Maybe something big.
There is also room to make ProdCo more profitable and that is happening, by removing all the unprofitable groups which were providing products that were not considered to be the core business.
These ongoing efforts seem to have LBT aligned with the Board and any ELT opposition solved by pushing them out of the company, so expect a continued, steady stream of changes as the company makes decisions about how much products it will continue to offer, and then acts on those decisions instead of the usual procrastination.
Then in a few years many options become possible, but that is because the business has been right-sized. At that point, there would be little motivation to break up the company. Breaking it up only seems to make sense right now, because of the IFS losses.
TLDR: It can't be broken up right now and once it can, there will be little reason to do so.
