I'd love to see an explanation of what went wrong from those guys.
I worked for GE for a couple of years. They are a conglomerate. They acquired other companies. I worked for a company where GE was the largest customer, and GE acquired it. If a company started to perform poorly, it wouldn't be long before it would either be sold or split apart. The company I was working at probably would have failed anyway due to rapid competition, but since GE used a lot of its products it was sort of a no brainer until an alternative was found.
Acquiring and sunsetting companies is not uncommon now, but back then it wasn't received well and backlash accumulated over time. They had/have a huge part of the jet engine market. Due to their size and executive connections, they were capable of landing large contracts, such as defense and aerospace.
They aren't successful if compared to Meta for example, that nets $70 billion per year.
GE acquired the power grid component of Alstom, a French company in 2014. That company was previously fined by the US DOJ for $772 million for FCPA violations (bribes). (This was back in the US World Police days).
