Analysts estimate the market value of GE Aerospace at more than $100 billion after the spinoff. It is benefiting from a surge in demand for aftermarket services because jet delivery delays by Boeing and Airbus are forcing airlines to fly older planes for longer. Last month, it forecast operating profit of about $10 billion in 2028. "We expect GE Aerospace's engine business flywheel to spin off decades of profitable growth," Nicolas Owens, equity analyst at Morningstar, wrote in a note.
