Be open to the idea that the buyer would proceed to part out the company, keeping just what they wanted.
Musk has a big AI project and Sam Altman has been claiming AI needs a lot of fabs. Neither would want x86, and Apple/Microsoft/Nvidia (etc) wouldn't want that either, so likely product groups get sold off to AMD or QCOM, or that is all that remains of Intel.
Anyone obsessing over mass layoffs is stuck in some version of an IDM model and that is clearly not is going on now. Mass layoffs would support keeping the company together and scaling down to profitability.
Instead, if the company is to be broken up, then unless the various buyers can get some synergies, the layoffs would be specific to each group being sold. The acquiring companies might even ramp up headcount, if they feel Intel was not fully realizing the potential or was unable to fully capitalize some group.
Hard to imagine any buyer of the company wanting to keep it as is, so I'd expect anything but that to be where Intel is at the end of 2025.
