United Technologies’ Sikorsky Split Is Just the Beginning

United Technologies Corp.’s plan to part with Black Hawk helicopters may be only the beginning.

The $110 billion industrial conglomerate announced Wednesday that it will sell or spin off Sikorsky Aircraft, a unit valued on average by analysts at about $8 billion as a stand-alone. Cutting ties with Sikorsky -- its lowest-margin business -- may help United Technologies bridge the 13 percent gap between its stock price and the roughly $137-a-share value that some analysts assign to its underlying assets.
