Santander Drive Auto Receivables Trust 2023-4 Annual Report: A Simple Breakdown

I’m here to help you understand the annual report for the Santander Drive Auto Receivables Trust 2023-4. Think of this as a plain-English guide to your investment, without the confusing financial jargon.

1. What does this trust do and how did it perform?

This isn't a typical company like Apple or Amazon. It is a "securitization trust"—a financial vehicle created by Santander Consumer USA to hold a pool of auto loans. You invest in this trust to receive payments as car buyers pay off their loans. In 2025, the trust continued its primary job: collecting payments and passing them to investors. It started with about $1.26 billion in subprime auto loans, which back the investments you hold.

2. Financial performance

Because this trust only holds specific loans, it doesn't have "revenue" or "profit" like a normal business. Its success depends on collecting loan payments and distributing cash as promised. The trust follows a set payment schedule, or "waterfall," to pay investors. As of 2025, the trust has successfully paid all noteholders on time. The system is working as planned, with loan losses staying within the expected range.

3. Major wins and challenges

Wins: The trust followed all servicing rules required by Regulation AB. This is a big win for investors because it proves Santander Consumer USA is handling collections and reporting correctly.

Challenges: A new legal issue has emerged. In February 2026, investors sued Wilmington Trust (the indenture trustee) regarding their role in other loan pools. While this doesn't involve your specific loans, it involves the same trustee. Keep an eye on this; legal distractions for a trustee can sometimes complicate administration or increase costs.

4. Financial health

The trust acts as a "pass-through" entity. It doesn't carry corporate debt or worry about liquidity like a regular business; it simply manages cash flow from car loans. Audits by PricewaterhouseCoopers confirm that the assets are being handled properly. The trust also keeps a reserve account—funded at 1% of the initial pool—to cover any gaps in monthly collections.

5. Key risks

• Legal Risks: The lawsuit against the trustee is a red flag. If the trustee faces major issues, it could create administrative hurdles or force a change in management.
• Loan Performance: Your investment depends on car buyers making their payments. Because these are subprime loans, the portfolio is sensitive to the economy. If unemployment rises or inflation hurts borrowers, more people may miss payments. This could drain the reserve account and hurt the value of lower-rated investments.

6. Leadership and strategy

The trust follows the original 2023 agreements. The roles of the servicer and trustees remain the same, ensuring consistency in how payments are collected and distributed.

7. Future outlook

The trust is in "run-off" mode. It will collect payments until the loans are paid off or the trust closes. As the pool matures, the loan balance will shrink. Eventually, the balance will be small enough for the servicer to buy the remaining loans and end the trust.

8. Market trends and regulations

The trust follows SEC reporting rules for asset-backed securities. It is currently in full compliance, providing monthly and annual reports to keep you informed.

Investor Tip: Since this trust is in "run-off" mode, your primary focus should be monitoring the monthly payment reports. Look for any significant spikes in loan defaults or changes in the reserve account balance, as these are the most direct indicators of whether your investment will continue to pay out as expected.
