Fair Isaac shareholders who lost money after the company’s stock fell following a Federal Housing Finance Agency announcement may be eligible to seek recovery, according to an investigation by Levi & Korsinsky, LLP. FICO stock opened down more than $172 per share, or over 20%, after the FHFA said changes could allow a competing credit score to be used in mortgage underwriting. The announcement came after market close on September 28, 2026. A few hours later, Rocket Mortgage said it would become the first mortgage lender to use VantageScore 4.0 as its preferred scoring model for all eligible loans, following four months of testing. The investigation is examining whether Fair Isaac made materially false or misleading statements about regulatory and competitive risks before the FHFA announcement, causing investors to buy FICO securities at inflated prices. Investors do not need to still own their shares, and there is no cost or minimum loss required to have losses evaluated. The firm says investors may submit brokerage records showing purchase dates, quantities, prices and any later sales for a no-cost, no-obligation review. Any resulting legal action would generally be handled on a contingency basis, with attorneys’ fees and expenses subject to court approval. Participation does not require court appearances or depositions.
