Mizuho analyst Dan Dolev on Tuesday publicly rebutted allegations made in a Muddy Waters short seller report dated March 17 that criticized SoFi Technologies’ accounting and credit reporting. The short seller claimed, among other things, that a $312 million loan sale should be treated as unrecorded debt, that SoFi used too low a discount rate on student loans in 2025, and that the company’s reported personal loan charge-off figures were understated.
The Muddy Waters piece, titled "SOFI: A Financial Engineering Treadmill Leaving Management Fat, Shareholders the Biggest Loser," argued that the $312 million transaction was not a true third-party sale, but rather a refinancing or borrowing that left at least $312 million of debt effectively off SoFi’s balance sheet. The report also flagged a 3.89% discount rate used for student loans in 2025 - described as 27 basis points below the 10-year U.S. Treasury yield - and produced an alternative calculation of personal loan charge-offs that suggested a materially higher rate than SoFi’s public reporting.
Dolev acknowledged the short seller’s report contained extensive detail and analysis, but said that SoFi’s public disclosures provide counterarguments that could refute the key points. On the $312 million item specifically, Dolev said his read is that the transaction was a sale of a senior secured loan. He pointed to remarks from SoFi’s CFO on the third quarter 2024 call in which management stated the company sold $312 million of senior secured loans at par execution.
According to Dolev, a regulated bank like SoFi would be expected to obtain a true sale opinion when representing a loan transfer as a sale. He cited the treatment of true sale criteria in SoFi’s 10-K filings for both 2023 and 2024, where the company discusses these issues under the Variable Interest Entities header in Note 1. SoFi also addresses sale versus secured borrowing criteria under the Transfers of Financial Assets header in both Note 1 and Note 4 of the 10-K, noting that transfers that do not qualify for sale accounting are reported as secured borrowings and that accounting depends on facts and circumstances.
Further documentary support is available in SoFi’s third quarter 2024 10-Q. The filing notes that the company sold a secured loan at par during the three and nine months ended September 30, 2024, and that the loan had an unpaid principal balance and accrued interest of $312.5 million. Dolev used these disclosures to frame his contention that the loan sale characterization in public filings differs from the short seller’s interpretation.
On the student loan discount-rate criticism, Muddy Waters argued SoFi used 3.89% for 2025 discounting, which the short seller described as 27 basis points below the 10-year Treasury yield. Dolev countered that SoFi’s student loan portfolio has a weighted-average life of roughly four years, and therefore the company’s use of a four-year SOFR-based benchmark would be reasonable rather than employing the 10-year Treasury as a discount-rate comparator.
Charge-offs were another focal point of the short seller report. Muddy Waters calculated a personal loan charge-off rate of roughly 6.1%, versus the 2.89% rate reported by SoFi, asserting that the company may be disposing of loans just before charge-off thresholds and that some delinquent loans were parked off balance sheet. Dolev noted that SoFi’s management has itself referenced a higher adjusted figure - 4.4% - when excluding approximately $90 million of late-stage delinquent personal loans, and the short seller also pointed to a 4.7% annualized charge-off rate.
Dolev said his own calculations show a result closer to management’s adjusted number. He cited a methodology that starts with an 8.4% Fitch cumulative gross loss, applies a 0.90 recovery factor, and divides by a 1.8 weighted average life for the loan, producing a figure around 4.2% - which Dolev described as supportive of a roughly 4.4% working estimate rather than the 6.1% Muddy Waters suggested.
The analyst suggested the short seller’s approach might be conflating different measures - including charge-offs for loans remaining on the balance sheet with 30-day delinquencies for loans that SoFi originated, later transferred, but for which it retained servicing involvement. Dolev said he believes SoFi does not publish 30-day delinquency data for loans that remain on the balance sheet, a distinction that could influence headline comparisons.
Muddy Waters framed SoFi as operating a "financial engineering treadmill," arguing the company is not building an organically healthy origination business but is instead relying on structures and loan marks that dilute shareholders while enabling management to meet bonus targets. The short seller alleged that off-balance-sheet arrangements disguised borrowings as revenue.
Mizuho, in response, maintained an Outperform rating on SoFi and kept a $38 price target. The firm’s rebuttal focuses on publicly available disclosures, management commentary and accounting notes that the analyst says undercut the short seller’s central assertions.
Summary - Mizuho analyst Dan Dolev rebutted a March 17 Muddy Waters short seller report that alleged SoFi misclassified a $312 million loan sale as a true sale rather than a borrowing, used an inappropriately low discount rate for student loans in 2025, and understated personal loan charge-off rates. Dolev cited SoFi’s public filings, management comments and accounting notes that he said support the company’s positions. Mizuho retained an Outperform rating and a $38 price target.
Key points
- Mizuho disputes Muddy Waters’ claim that a $312 million secured loan sale was effectively unrecorded debt, pointing to management commentary and 10-Q/10-K disclosures that describe the transaction as a sale at par.
- On student loan discounting, Mizuho argues SoFi’s use of a shorter-term benchmark is reasonable given the portfolio’s roughly four-year weighted-average life.
- Charge-off math is contested: Muddy Waters presented a higher charge-off estimate, while Mizuho highlights management’s adjusted 4.4% figure and produces a calculation that yields roughly 4.2%.
Risks and uncertainties
- Accounting interpretation - Disputes over whether a loan transfer qualifies as a true sale versus a secured borrowing could materially change reported leverage and liabilities; this primarily affects banking and financial reporting sectors.
- Credit metric transparency - Differing methods to calculate charge-offs and delinquency measures create uncertainty for credit assessment and valuation models in consumer lending and fintech sectors.
- Investor perception - Short seller allegations about off-balance-sheet financing and management incentives can influence market sentiment and share price volatility in the financial services and fintech space.
