MGE Energy Inc's stock experienced a significant pre-market decline of 5.82% on Thursday, as investors reacted to the company's announcement of a substantial equity offering.

The utility company revealed plans for an underwritten public offering of 3,300,331 shares at $75.75 per share, representing a total offering of approximately $250 million.
