SoFi Technologies (SoFi)

SoFi Technologies spent years as one of the most debated growth stories in American fintech. The investment thesis was straightforward and credible: build a full-stack digital bank with no branches, cross-sell aggressively into a growing member base, use a banking licence to fund loans with cheap deposits rather than expensive wholesale capital, and let the revenue compound until the sceptics ran out of arguments. In 2025, the revenue arrived. By Q1 2026, the company was posting its best results in its history by every measurable standard. The stock, trading on the NASDAQ under the ticker SOFI, is down approximately 51% from its all-time high of $32.73 set in November 2025. Understanding why those two things coexist is the entire analytical task here.

What SoFi Actually Does

SoFi operates as a fully digital, FDIC-insured bank in the United States. Its business spans three reportable segments: Lending, Financial Services, and the Technology Platform.

The Lending segment generates revenue from personal loans, student loan refinancing, and home loans. Personal loans are the largest component, with $8.3 billion originated in Q1 2026 alone, representing 51% growth year on year. Student loan refinancing originated $2.6 billion in the same quarter, up 119% year on year, and home loans added $1.2 billion, up 137%. Total loan originations reached a record $12.2 billion in Q1 2026, a 68% jump compared with the same period in 2025.

The Financial Services segment includes SoFi Money, a high-yield checking and savings account, SoFi Invest, a brokerage and automated investing product, a credit card, and SoFi Protect, which covers insurance. This segment generated $428.5 million in net revenue in Q1 2026, up 41% year on year. The segment is growing quickly because each new member represents multiple potential products, and SoFi’s cross-sell rate is improving: 43% of new products opened in Q1 2026 came from existing members, up from 36% in Q1 2025.

The Technology Platform segment, which operates under the Galileo and Technisys brands, provides financial infrastructure to third-party financial institutions and enterprise clients. Galileo processes payments and provides card issuance infrastructure. Technisys is a core banking system platform acquired in 2022. Together, the Financial Services and Technology Platform segments generated $503.6 million in net revenue in Q1 2026, an increase of 24% from the prior year period. The Technology Platform has been the weakest part of the business recently, with a large client transitioning off the platform creating headwinds. Management has guided for approximately $325 million in Technology Platform net revenue for the full year 2026.

The Banking Licence: Why It Changed the Economics

SoFi received its bank charter in early 2022, and the financial impact of that decision continues to compound. With a banking licence, SoFi can accept retail deposits directly, which gives it access to a funding source that is substantially cheaper than the wholesale capital markets it previously relied on. This matters because a neobank funding its loan book at the interbank rate is structurally disadvantaged against a licensed bank that pays depositors 4 to 5 percent while lending at 10 to 15 percent.

Total deposits reached $40.2 billion by the end of Q1 2026, an increase of $2.7 billion in a single quarter. Approximately 96% of SoFi’s funding is now deposit-based, up from 78% in 2023. This structural shift has reduced SoFi’s estimated funding expenses by approximately $622 million annually compared with its pre-bank funding costs. The net interest margin of 5.94% in Q1 2026 is meaningfully above what most regional banks achieve, which typically operate in the 3 to 4 percent range. That margin reflects both the higher-yielding nature of consumer loans and the disciplined management of funding costs that the deposit franchise enables.

SoFi operates with no branch network. The implications for the cost structure are significant. The cost-to-serve per member is dramatically lower than that of branch-dependent incumbents, and scale benefits are visible in the numbers: adjusted EBITDA margins reached 31% in Q1 2026, a level that most traditional banks would consider aspirational.

The Headline Numbers

Full-year 2025 adjusted net revenue was $3.6 billion, up 38% year on year. Adjusted EBITDA for 2025 was $1.1 billion, up 58% year on year, at a margin of 29%. This was the first time the company exceeded $1 billion of EBITDA in a calendar year.

Q4 2025 broke the $1 billion quarterly revenue threshold for the first time in the company’s history, with adjusted net revenue of $1.013 billion, up 37% year on year. Q1 2026 extended that record, delivering $1.1 billion in GAAP net revenue, up 43% year on year, and $1.087 billion in adjusted net revenue, up 41%. Adjusted EBITDA grew 62% in Q1 2026 to $340 million. Net income was $166.7 million, more than double the $71.1 million reported in Q1 2025. Diluted earnings per share reached $0.12, up from $0.06 in the prior year period.

The membership base grew 35% year on year to reach 14.7 million members by the end of Q1 2026. Total products used by members reached 22.2 million, up 39% year on year, with approximately 1.8 million new products added in Q1 alone. This is the metric that most directly validates the cross-sell thesis: members are not just joining, they are adopting multiple SoFi products over time, which increases their lifetime value and reduces the effective customer acquisition cost on a per-product basis.

The Disconnect Between the Business and the Stock

The core tension in the SoFi thesis in 2026 is that the company is performing at or above its own projections while the stock is approximately 51% below its November 2025 all-time high of $32.73.

Several distinct pressures have weighed on the share price since the peak. In December 2025, the company raised $1.5 billion through a share offering priced at $27.50, creating a visible group of underwater investors at that level. In March 2026, short-seller firm Muddy Waters Research published a report that described SoFi as a “financial engineering treadmill.” The report’s primary allegations centred on three claims: that SoFi’s adjusted EBITDA was significantly inflated relative to accounting adjustments; that the company’s personal loan charge-off rate was materially understated because delinquent loan sales were not fully captured in the headline metric; and that student loan portfolios carried overvalued assumptions in their fair value models. SoFi’s management responded immediately and aggressively, characterising the report as “factually inaccurate and misleading” and indicating the company was exploring legal action. The Muddy Waters claims deserve serious engagement rather than dismissal, because the firm has a credible track record and the specific accounting questions it raised, particularly around charge-off rate methodology and off-balance-sheet loan structures, are technically complex enough to leave genuine analytical uncertainty.

Then on 29 April 2026, Q1 earnings arrived with record numbers across every major metric. The stock fell 13% on earnings day, not because the results were poor but because management declined to raise its full-year guidance. Investors had priced in a guidance upgrade after a quarter where the word “record” appeared more times than any previous earnings release. The guidance remained unchanged at approximately $4.655 billion in adjusted net revenue and $825 million in adjusted net income for the full year 2026. Management cited elevated interest rates, tighter credit conditions, and conservative consumer behaviour as reasons for maintaining rather than raising the outlook.

One notable counter-signal emerged shortly after earnings: CEO Anthony Noto purchased approximately 15,878 shares personally on 9 May for roughly $250,000. Insider buying at a meaningful dollar value, particularly from a CEO in the immediate aftermath of a stock decline driven partly by his own guidance decision, carries informational content. It does not resolve the Muddy Waters claims, but it is a data point that belongs in the analysis.

Valuation Context

At approximately $16 as of early May 2026, SoFi trades at roughly 4.3 times its guided 2026 revenue of $4.655 billion. On a forward earnings basis, the stock trades at approximately 26.7 times the company’s guided $0.60 in adjusted earnings per share for 2026. For comparison, traditional bank peers such as Ally Financial trade at approximately 7.6 times forward earnings, and LendingClub trades at approximately 8.3 times. SoFi carries a premium to those peers because it is not purely a lender. The Galileo and Technisys technology platform businesses, which serve approximately 158 million enabled accounts across enterprise clients, carry higher multiple characteristics than a straightforward consumer lender.

Management has provided medium-term guidance of at least 30% compounded annual revenue growth and 38% to 42% compounded annual EPS growth from 2025 through 2028. If those targets hold, the current multiple, on a price-to-growth basis, does not look expensive for a financial technology company. The question is whether those targets hold, and that question cannot be separated from the Muddy Waters allegations about how the company accounts for credit losses in its lending book.

The Primary Risk

SoFi’s lending book is concentrated in personal loans and student loan refinancing to prime and near-prime borrowers. The reported annualised net charge-off rate on personal loans in Q4 2025 was 2.80%, down 57 basis points year on year, which management presents as evidence of strong credit quality in its existing book. Muddy Waters disputes the methodology of that calculation, arguing that when delinquent loan sales are factored into the denominator appropriately, the true charge-off rate on the total serviced portfolio is materially higher, and that Fitch and Morningstar DBRS independently corroborate charge-off assumptions closer to the Muddy Waters estimates than to SoFi’s reported figures. SoFi disputes this characterisation entirely. Until independent analysis or subsequent disclosures provide more clarity, the credit quality of the personal loan book is a genuine risk variable, not a resolved one.

The second risk is macro-driven. A sustained period of elevated unemployment in the United States, in which consumers with personal loans begin defaulting at higher rates, would compress both net interest income and provision expenses simultaneously. The 5.94% net interest margin looks attractive in the current rate environment. It becomes a structurally different number in a recession where the denominator of that margin is experiencing significant credit stress.

What This Means for South African Investors

SoFi is listed on the NASDAQ and is not available on the JSE, but it is accessible to South African retail investors through EasyEquities via the USD account. For an SA investor, a position in SoFi provides two overlapping exposures: the specific thesis around US digital banking disruption, and pure US dollar exposure, which functions as a rand hedge. Every rand that moves into a USD-denominated asset benefits if the rand weakens against the dollar, which is a structural consideration for South African investors with a long investment horizon.

The stock’s decline from its $32.73 all-time high to approximately $16 means that investors entering today are doing so at a materially better price than those who bought at the peak or at the December 2025 capital raise price of $27.50. Whether that discount is justified by the Muddy Waters allegations, the unchanged guidance, or genuine macro risk is the question each investor must evaluate independently.

The Technology Platform guidance of $325 million for 2026 is the most important near-term data point to monitor. A stabilisation or improvement in that segment removes one of the legitimate concerns from the post-Muddy Waters narrative. The Q2 2026 earnings release, expected around 27 July 2026, will be the next significant opportunity for management to update full-year guidance. A guidance raise at that point would be the single most direct catalyst for re-rating the stock.

The Analytical Conclusion

SoFi is delivering results it did not consistently deliver for most of its public company history: $1.1 billion in quarterly revenue, 35% member growth, 41% top-line expansion, a net interest margin above 5.9%, and ten consecutive profitable quarters. The stock is approximately 51% below its all-time high because a short-seller raised specific and technically substantive questions about accounting methodology, because management held guidance flat against strong Q1 results, and because a macro environment characterised by higher interest rates and cautious consumer behaviour creates legitimate uncertainty about the personal loan book.

The business has structural advantages that are not in dispute: the banking licence, the deposit franchise, the improving cross-sell rate, and the cost structure of a branchless bank at scale. The open questions, principally around credit quality accounting and the Technology Platform trajectory, are not minor footnotes. They are the variables that determine whether the current multiple reflects fair value or a persistent discount.

For an investor with a three to five year horizon who believes that digital banking continues to take share from branch-based incumbents, that the deposit franchise and cross-sell economics will compound at the rates management projects, and that the Muddy Waters credit quality concerns are overstated, the risk-reward at current prices is more compelling than it was at $32.73. The personal loan credit quality is the variable that most directly determines whether that assessment holds.
