- Underestimated Charge-Off Rates: SoFi reported a personal loan net charge-off rate of 2.80%, yet Muddy Waters claims this figure does not account for delinquent loans sold within 120 days, suggesting the actual charge-off rate could be closer to 6%, raising concerns about credit risk assessment.
- Management Incentive Issues: Muddy Waters alleges that SoFi's management has engaged in financial engineering to boost performance for bonuses, with CEO and CFO extracting over $58 million through prepaid variable forward contracts, potentially impacting corporate governance and transparency.
- Allegations of Financial Misrepresentation: Muddy Waters asserts that SoFi employs excessively low charge-off and discount rates in calculating fair value gains on its loan portfolios, which artificially inflates its EBITDA by hundreds of millions, undermining investor confidence in the company's financial health.

- Termination of SAVE Plan: A federal appeals court has ordered the end of the SAVE plan, leaving over 7.2 million borrowers facing increasing debt, as they have been in forbearance since July 2024 without progress towards loan forgiveness.

- Challenges in Applying for New Plans: With the U.S. Department of Education's limited capacity to process applications, borrowers who wait until the end of the SAVE plan to apply for new income-driven repayment options may face longer wait times, increasing their financial risks.
- Cost of Switching Repayment Plans: While the Income-Based Repayment (IBR) plan is viewed as a better option, borrowers switching from SAVE could see their monthly payments double, adding further financial burden to those already under stress.
