FICO stock plunges 26% after regulator moves to erase its mortgage-scoring edge

Shares of Fair Isaac Corporation, the company behind the FICO score that has anchored American mortgage underwriting for more than three decades, fell as much as 26 percent on Tuesday after the federal regulator overseeing Fannie Mae and Freddie Mac said the two mortgage giants would merge a rival credit-scoring model into the same pricing grid that FICO has effectively controlled alone. The announcement, posted late Monday on social media by Federal Housing Finance Agency Director Bill Pulte, marks the sharpest escalation yet in a year-long regulatory campaign to break FICO's grip on conventional mortgage pricing.

Pulte said Fannie Mae and Freddie Mac would move to "one pricing grid," with VantageScore, a credit model jointly owned by Equifax, TransUnion and Experian, joining what he called the existing "FICO Classic" grid. He did not give an effective date or publish a replacement pricing matrix, but the message was enough to send Fair Isaac's stock to a fresh 52-week low.

The numbers

Fair Isaac shares briefly touched $595.19, a new 52-week low, before recovering slightly to trade around $624, down roughly $217, or about 26 percent, on the day. That left the company with a market capitalization near $13.5 billion, down about 63 percent from the 52-week high of $1,998.01 the stock reached last October, according to trading data reviewed on stockanalysis.com. The three credit bureaus that jointly own VantageScore also moved on the news, though far less dramatically: Equifax fell about 6.7 percent, TransUnion dropped roughly 4 percent and Experian slipped about 1.2 percent, according to a Tuesday roundup of the day's trading.

How the fight over mortgage scoring got here

The immediate trigger was Pulte's late-Monday post, but the underlying dispute dates to April, when FHFA and the Department of Housing and Urban Development jointly announced that Fannie Mae and Freddie Mac would accept VantageScore 4.0 for the first time, ending FICO's status as the sole credit model accepted on loans backed by the two government-sponsored enterprises. That rollout began as a limited pilot with roughly 21 large lenders, including Rocket Mortgage and PennyMac.

On September 9, Fannie Mae and Freddie Mac widened access considerably. Fannie's Lender Letter and Freddie's companion bulletin, described on Fannie Mae's newsroom and detailed further on Freddie Mac's credit-score models page, opened VantageScore 4.0 to every approved seller without prior approval. But the two enterprises kept separate pricing grids for the two scores, with loan-level price adjustments for VantageScore calibrated roughly 20 points more conservatively than for an equivalent FICO score — treating a 750 VantageScore, in effect, like a 730 FICO score. An analysis by mortgage-analytics firm Milliman found that only about a quarter of loans priced better under VantageScore, while roughly 40 percent would have been cheaper on Classic FICO, and as of August VantageScore accounted for just 5.6 percent of loans the enterprises securitized despite months of availability.

Monday's announcement proposes to erase that 20-point buffer altogether, putting the two scores on equal footing for pricing purposes — a move Pulte said followed complaints from lenders and consumers about a two-grid system he described as one that "makes zero sense." It also builds on a broader dispute this year between FHFA and FICO, which has separately clashed with the agency over wholesale royalty-fee increases that contributed to a 16 percent single-day drop in Fair Isaac shares in May, part of a decline that has made FICO the worst-performing stock in the S&P 500 this year, according to earlier analyst commentary on the stock's slide.

Who is affected

Roughly 70 percent of the U.S. mortgage market flows through loans eligible for purchase by Fannie Mae and Freddie Mac, meaning the pricing-grid change touches nearly every conventional home loan originated going forward. For borrowers, the enterprises and VantageScore's backers argue the shift widens access to credit for people with thin or no traditional credit files — VantageScore has said its model can score tens of millions of consumers that Classic FICO cannot, in part by using rental, utility and telecom payment history. For lenders, a single grid removes an operational headache but also raises the prospect of "score shopping," in which loan officers steer applicants toward whichever model produces a lower rate. For Fair Isaac, which derives a large share of its Scores segment revenue from per-loan royalties on mortgage originations, equalized pricing lowers the barrier for lenders to substitute a cheaper rival score — VantageScore has been offered at promotional prices as low as roughly a dollar, against FICO Classic and FICO's newer 10T model priced around $10.

What analysts and executives are saying

Reaction on Wall Street split along familiar lines. Craig Maurer of FT Partners said that with pricing now aligned, "VantageScore could see increased adoption, with a lower hurdle for more favorable LLPA pricing," according to the Yahoo Finance analyst roundup. Jaret Seiberg of TD Cowen was more skeptical, noting what he called a regulatory inconsistency: FHFA had previously concluded that VantageScore overstated borrower credit quality by roughly 20 points relative to FICO, yet the new grid now treats the two scores as interchangeable.

"Our longer-term worry is that this creates an incentive for FICO and Vantage to compete on producing scores that result in the lowest LLPAs rather than on the risk of default," Seiberg wrote, according to Yahoo Finance's compilation of analyst reaction.

RBC Capital's Ashish Sabadra maintained an Outperform rating on Fair Isaac despite flagging the same risks, pointing to continued demand for FICO scores in the private-label mortgage-securities market as a partial floor under the company's business. On the lender side, Rocket Companies chief executive Jay Bray, whose firm began offering VantageScore 4.0 as an option earlier this year, framed the shift as overdue competition: "The mortgage industry has relied on one credit scoring model for decades. Competition is healthy," Bray said, adding that Rocket "chose the one that helped more qualified clients," a remark included in coverage of Tuesday's selloff.

Fair Isaac did not immediately issue a public statement responding to Monday's post. In earlier rounds of its dispute with FHFA, the company has defended its Direct License program, which lets lenders buy FICO scores at alternative price points, arguing that credit bureaus' own processing fees — not FICO's pricing — are what raise costs for borrowers.

What happens next

The practical effect of Monday's announcement remains unsettled. Pulte's post did not specify when a unified grid would take effect or what the new loan-level price adjustments would look like, leaving lenders, investors and rating analysts to wait for formal selling-guide updates from Fannie Mae and Freddie Mac before the change is binding. Until then, lenders retain the option to run loans through either scoring model, and the roughly 20-point pricing gap that has limited VantageScore's uptake so far will remain in place.

Investors are likely to look for clarity in Fair Isaac's next quarterly report, filed as always with the Securities and Exchange Commission, for management's response to a policy shift that, taken together with this year's earlier moves, has erased close to two-thirds of the company's market value since last fall. Congressional aides and housing-policy analysts, meanwhile, have noted that the underlying legal basis for opening the door to rival scores — the Credit Score Competition Act of 2018 — anticipated exactly this kind of multi-model competition, even if the pace and manner of FHFA's rollout under Pulte has drawn criticism from both the company being displaced and some economists who warn that pricing scores to match rather than to reflect default risk could reintroduce the kind of mispricing that regulators have spent years trying to stamp out of the mortgage market.
