This happened to industrial company Coherent (NYSE: COHR) this week, and happy shareholders reacted by pushing the stock up in value. On Tuesday, Coherent divulged that a pair of Japanese industrial companies, Mitsubishi Electric (OTC: MIELY) and Denso, will together invest $1 billion into its silicon carbide operation. The news comes several months after Coherent announced it was conducting a strategic review of the silicon carbide unit.
