MGIC INVESTMENT CORPORATION

NOTICE OF CHANGE OF LOCATION AND NOTICE OF CHANGE IN VOTING INSTRUCTIONS FOR

THE ANNUAL MEETING OF SHAREHOLDERS TO BE HELD ON APRIL 23, 2020

To our Shareholders or Record and Participants in our Profit Sharing and Savings Plan:

Due to the ongoing public health impact of the coronavirus disease 2019 ("COVID-19") outbreak and to support the health and well-being of our associates and shareholders, NOTICE IS HEREBY GIVEN that the location of the Annual Meeting of Shareholders of MGIC Investment Corporation (the “Company”) has been changed. As previously announced, the Annual Meeting of Shareholders (the “Annual Meeting”) will be held on Thursday, April 23, 2020 at 9:00 a.m., Central Time; however, the Annual Meeting will now be held in a virtual meeting format only, via live webcast. You will not be able to attend the Annual Meeting physically. It is the Company's current intent to return to an in-person format for its future annual meetings of shareholders.

As described in the proxy materials for the Annual Meeting previously distributed, you are entitled to participate in the Annual Meeting if you were a shareholder as of the close of business on March 6, 2020, the record date, or hold shares as a participant in the MGIC Profit Sharing and Savings Plan.

Voting Your Shares

The attached proxy card (the “Replacement Proxy Card”) contains new instructions to be used for voting your shares. For your vote to be counted, you must use the new instructions to vote your shares, even if you have already voted using the instructions on the original proxy card that was mailed to you. We apologize for any inconvenience. If you hold shares as a participant in our Profit Sharing and Savings Plan, the plan trustee will vote shares held in your account in accordance with your instructions and the plan terms. The plan trustee will only vote the shares for you if your instructions are received at least three business days before the Annual Meeting date.

Attending the Virtual Meeting

You may attend the Annual Meeting by accessing https://www.virtualshareholdermeeting.com/MTG2020. You must enter the control number found on the Replacement Proxy Card. Because of the change in the format of the meeting due to the COVID-19 outbreak, management will not report on our performance during the last year. However, to the extent feasible, management will answer questions submitted during the meeting that are pertinent to the business of the meeting. The rules of the meeting will provide additional information on our question and answer process. Once admitted to the meeting, you may submit questions, vote (if you were a shareholder of record) and view our list of shareholders during the Annual Meeting by following the instructions that will be available on the meeting website. Registration will begin 15 minutes before the start time of the meeting. A telephone number that you may call for technical assistance will be available on the meeting website. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting by one of the methods described on your Replacement Proxy Card.
