Dear Stockholder:

You are cordially invited to attend the 2026 Annual Meeting of Stockholders of Radian Group Inc. (the “Annual Meeting”), which will be held exclusively in virtual format via live audio webcast at 9:00 a.m. Eastern Daylight Time on May 21, 2026. The accompanying Notice of 2026 Annual Meeting of Stockholders and 2026 Proxy Statement describe the items to be considered and acted upon by the stockholders at the Annual Meeting. There is no physical location for the Annual Meeting.

For our Annual Meeting, we have elected to use the internet as the primary means of providing our proxy materials to stockholders. Stockholders of record on the record date will receive a Notice of Internet Availability of Proxy Materials (the “Notice”) with instructions for accessing the proxy materials. The Notice also provides information on how to vote, how to attend the Annual Meeting, and how stockholders who wish to request paper copies of our proxy materials, including a proxy card, may obtain them free of charge.

Regardless of whether you plan to attend the virtual Annual Meeting, we hope you will vote as soon as possible. Stockholders of record can vote their shares by using the internet. If you received your materials by mail, you also may vote your shares by telephone or by marking your votes on the enclosed proxy card, signing and dating it, and mailing it in the enclosed envelope. If you attend the virtual Annual Meeting, you may revoke your proxy, if you wish, and vote your shares during the meeting electronically via the internet. Because the representation of stockholders at the Annual Meeting is very important, we thank you in advance for your participation.

Sincerely,

Elizabeth A. Diffley

Senior Corporate Counsel and Corporate Secretary

NOTICE OF 2026 ANNUAL MEETING OF STOCKHOLDERS

Instead of paper copies of this notice of meeting, our 2026 Proxy Statement and our 2025 Annual Report to Stockholders, many stockholders received a Notice of Internet Availability of Proxy Materials (the “Notice”), which Notice was mailed to stockholders beginning on or about April 2, 2026. The Notice provides instructions on how to access these documents over the internet and information on how stockholders who wish to request paper copies of these proxy materials, including a proxy card, may obtain them free of charge. Electronic delivery enables us to more cost effectively provide you with the information you need while reducing the environmental impact of printing and mailing paper copies.

We have determined that it is in the best interest of Radian and its stockholders to hold the 2026 Annual Meeting of Stockholders (the “Annual Meeting”) virtually via live audio webcast.
