CG Power is a 90-year-old electrical franchise that was nearly destroyed by fraud and then rebuilt into one of the best turnarounds the Indian market has seen, a 50-bagger from its lows, with a brand-new semiconductor leg the previous owner never imagined. Here is the journey, year by year.
The pattern is the point
The Avantha era nearly destroyed a 90-year-old industrial franchise; the Murugappa Group bought the asset at a distressed price, restructured it to net cash, and bolted on a semiconductor leg the previous owner never imagined. The best turnarounds are not merely operational, they pair a cleaned-up balance sheet with a genuinely new growth engine, which is exactly what re-rated CG Power.
