MFA · CIK 0001055160
What MFA Financial, Inc. told the SEC could break it.
MFA's risk runs through the mortgages it owns. The loans and securities in its portfolio are geographically concentrated, with significant exposure in California, Florida, Texas, Georgia and New York, tying it to those regions' economic, regulatory, climate and catastrophe risks. Because it doesn't interface with borrowers, it relies entirely on third-party servicers to service and manage those mortgages, so its returns hinge on servicer performance and foreclosure/liquidation outcomes. And about $3.3 billion — 25% of total assets at year-end 2025 — is invested in Agency MBS, leaving it exposed to mortgage-finance reform and the uncertain future role of Fannie Mae and Freddie Mac.
