As somebody else said, this is the best deal GE has done in the last 20 years, and everyone should be happy about it.
Instead of going through an IPO process that might drag out or that might not net as much cash as desired, he did a clean sale of a division to a willing strategic buyer who had the cash to pay us. Strategic buyers pay more than financial buyers, so this is better than any deal we would do with a Private Equity firm. Also with the IPO there was always the risk of a market downturn that would spoil the IPO or hurt the share price of the shares GE would have retained. Those risks are now off the table.
As for what to do with the rest of healthcare, it can still be IPO’d if desired. Alternately, it is small enough now that a sale to a strategic buyer is possible.
