MGE Energy 2020 Annual Meeting Update

This is an important update regarding our Annual Meeting on May 19, 2020, at 11 a.m. CST.

Since the printing of your proxy materials, we have modified the format of our Annual Meeting from an in-person meeting to a virtual meeting.

Based on restrictions and guidance from federal, state and local public health agencies concerning the COVID-19 coronavirus, MGE Energy has made this modification in the interest of the safety of our shareholders, employees and broader community.

Please use your control number included in your proxy materials to attend the meeting either online or by phone.
