This would IMHO be a way of Ford deleting debt and liabilities.
on splitting shares, it could be arranged so that the ICE company would carry the debt, old factories and the majority of the employees, with the new EV business relatively debt free. EV company will then hold most of the IP, brand and patents, much of which would then be licensed back to the ICE company (sucking more money out of the old ICE business)
The ICE business would then become unprofitable over time and ultimately go into bankruptcy, taking with it its debts, the unprofitable factories, and the costs of laying off staff - leaving the EV business clean and debt free and holding the valuable assets.
Should there be a share split, look to see who owns the debt, brand and the IP. This will tell the true story of what's really going on.
