Fair Isaac shares extended their sell-off Wednesday after Federal Housing Finance Agency Director Bill Pulte said Fannie Mae and Freddie Mac would replace separate mortgage pricing structures with one grid, giving VantageScore 4.0 the same treatment as Classic FICO. TransUnion extended its $0.99 VantageScore 4.0 pricing through December 2028, while adoption reached more than 1,100 mortgage lenders, including nine of the 15 largest U.S. originators. BofA Securities downgraded Fair Isaac from Buy to Neutral and cut its price target from $1,400 to $700. Rocket Mortgage has selected VantageScore 4.0 as its preferred model for eligible loans. Fair Isaac has fallen approximately 60% in 2026, and Levi & Korsinsky, LLP is investigating whether the company made materially false or misleading statements about regulatory and competitive risks, without establishing wrongdoing or liability.
