Regulation FD Disclosure (Form 8-K)

On March 23, 2026, the Society of Lloyd's ("Lloyd's") posted on its investor relations website the syndicate annual accounts for the year ended 31 December 2025 for syndicates participating in the Lloyd's market, including Syndicate 1301, the Lloyd's syndicate through which Inigo Limited ("Inigo") writes insurance and reinsurance business through its subsidiaries.

Inigo, which Radian Group Inc. ("Radian") acquired on February 2, 2026, is the parent company of both Inigo Managing Agent Limited, which manages Syndicate 1301, and Inigo Corporate Member Limited, which provides capital and underwriting capacity for Syndicate 1301. The Syndicate 1301's annual accounts for the year ended 31 December 2025 (the "Syndicate 1301 Accounts"), which can also be found at https://www.radian.com/-/media/650F6F163C0E4CEFAF5B77F14D51263A.ashx?rev=df270b5f-aadf-4d5e-b575-a8219ad54e67, are prepared on a UK GAAP basis and present the results of the syndicate on a standalone basis, not the full consolidated financial statements of Inigo. As a result, the Syndicate 1301 Accounts are not directly translatable to the financial statements and financial information that will be filed by Radian and should be reviewed only in the context in which they are presented.

Financial statements and pro forma financial information required by Items 9.01(a) and (b) of Form 8-Kwith respect to Radian's acquisition of Inigo will be filed by amendment to Radian's Current Report on Form 8-Kfiled on February 3, 2026. We plan to file these financial statements, which will include the audited 2025 consolidated financial results for Inigo on a US GAAP basis, no later than April 17, 2026.

We use our investor relations website, radian.com/for-investors,as a means of disclosing information which may be of interest or material to our investors and for complying with disclosure obligations under the SEC's Regulation FD, which in the future is expected to include certain Inigo reports and other information. Accordingly, investors should monitor our investor relations website, in addition to following our press releases, SEC filings, public conference calls and webcasts.
