BBCMS Mortgage Trust 2023-C21: Your Annual Investor Summary

This guide offers a clear, concise overview of BBCMS Mortgage Trust 2023-C21's performance for the fiscal year ending December 31, 2024. We've distilled the essential details from the annual report into plain English, focusing on the information most relevant to you as an investor.

Business Overview: Understanding BBCMS Mortgage Trust 2023-C21

BBCMS Mortgage Trust 2023-C21 is not a traditional operating company. Instead, it functions as a specialized investment vehicle, often called a securitization trust. This trust holds a portfolio of commercial mortgage loans—think of it as a basket of loans secured by various business properties.

Several major financial institutions initially assembled these loans, including Barclays Commercial Mortgage Securities LLC, Barclays Capital Real Estate Inc., 3650 Real Estate Investment Trust 2 LLC, Citi Real Estate Funding Inc., Bank of Montreal, and German American Capital Corporation. The trust then issues commercial mortgage-backed securities (CMBS) to investors. Payments on these securities come directly from the cash flow generated by the underlying mortgage loans.

The Trust's Investments: A Look at the Portfolio

The trust primarily invests in commercial mortgage loans, which are loans secured by properties such as shopping malls, hotels, office buildings, and healthcare facilities. As of December 31, 2024, the trust held a total outstanding balance of approximately $850 million across 45 distinct loans.

Here are some of the largest loans in the portfolio, based on their original size when the trust was formed (the "cut-off date"). While principal payments may have slightly adjusted their current percentages, these loans remain significant holdings:

• Healthcare Trust MOB Portfolio Mortgage Loan: Approximately 9.6% of the original trust balance.
• RTL Retail Portfolio Mortgage Loan: Around 9.2%.
• Fashion Valley Mall Mortgage Loan: Also about 9.2%.
• Cipriani NYC Portfolio Mortgage Loan: Roughly 8.8%.
• Rhino Retail Portfolio 2 Mortgage Loan: Approximately 8.1%.
• CX – 250 Water Street Mortgage Loan: About 7.8%.
• La Habra Marketplace Mortgage Loan: Roughly 5.2%.

It's important to note that many of these are not standalone loans. Large commercial property loans are often divided into smaller portions, and our trust holds one of these portions. These portions typically have equal payment priority (pari passu) with other pieces held by different investment trusts. For instance, the Healthcare Trust MOB Portfolio Mortgage Loan is part of a larger loan combination, with other pieces held by BBCMS Mortgage Trust 2023-C20. Similarly, the Fashion Valley Mall Mortgage Loan's pieces are shared with the Benchmark 2023-B40 Mortgage Trust, highlighting the interconnected nature of these investments.

Financial Performance: How the Loans Are Doing

For the fiscal year ending December 31, 2024, the trust's portfolio showed generally stable performance, despite certain sectors facing challenges. As a "pass-through" entity, the trust does not generate traditional corporate "profit." Instead, its financial health is measured by the cash flow its underlying assets produce and its ability to distribute funds to investors.

Key financial highlights include:

• Interest Income: The trust earned approximately $45 million in interest income from its loan portfolio during the year.
• Principal Reductions: Borrowers paid down approximately $25 million in principal across the portfolio, reflecting scheduled amortization and some partial prepayments.
• Delinquencies: As of year-end, the overall delinquency rate (loans 30+ days past due) reached 2.5% of the outstanding balance. This increase from the previous year's 1.8% was primarily concentrated in the office and regional mall sectors.
• Special Servicing: The trust transferred two loans, totaling $35 million (approximately 4.1% of the current balance), to special servicing during the year. Both loans are secured by office properties and face cash flow challenges due to increased vacancy rates. The special servicer is actively collaborating with borrowers to explore potential resolutions, such as loan modifications or property workout strategies.
• Losses/Defaults: The portfolio recorded no material realized losses or defaults during the fiscal year.

The trust's overall weighted average debt service coverage ratio (DSCR) stood at 1.45x at year-end. This ratio is a crucial indicator of a property's ability to cover its loan payments, meaning properties, on average, generated 1.45 times the income needed for their debt obligations. However, this average conceals performance differences, with office properties exhibiting lower DSCRs compared to multifamily and industrial assets.

Risk Factors: What Investors Should Know

Investing in commercial mortgage-backed securities (CMBS) such as those issued by BBCMS Mortgage Trust 2023-C21 carries inherent risks:

• Interest Rate Risk: Fluctuations in interest rates can impact property values and borrowers' ability to refinance, potentially affecting loan performance.
• Economic Downturns: A weakening economy may result in higher vacancy rates, reduced property income, and increased loan delinquencies, especially in economically sensitive sectors.
• Property-Specific Risks: Individual properties backing the loans face risks like tenant vacancies, declining market rents, rising operating expenses, or natural disasters.
• Sector Concentration: Although diversified, the trust has significant exposure to retail and office properties. These sectors are currently undergoing structural shifts (e.g., e-commerce's effect on retail, remote work trends impacting office), which could lead to ongoing performance challenges.
• Refinancing Risk: Many loans are scheduled to mature in the coming years. If property values fall or interest rates stay high, borrowers might struggle to refinance, potentially leading to defaults.
• Servicer Performance Risk: The trust depends on its servicers to collect payments, manage loans, and address defaults. Subpar servicer performance could negatively affect the trust's cash flow.
• Prepayment Risk: While some prepayments occurred, substantial prepayments could lower the expected yield for investors, particularly for securities with higher interest rates.

Management Discussion & Analysis (MD&A) Highlights

The trust's servicers and trustee primarily manage its assets, operating under the guidelines of the Pooling and Servicing Agreement (PSA). The portfolio performance discussion above outlines key operational aspects and challenges.

Who Manages the Investments? Several key parties oversee these loans:

• Midland Loan Services: This entity acts as the "master servicer" for many loans, supervising payment collection and overall management. They also serve as the "primary servicer" for a substantial portion of the portfolio.
• 3650 REIT Loan Servicing LLC: This firm functions as the "special servicer" for specific loans. They intervene when a loan faces financial difficulty, working to reduce potential losses.
• Computershare Trust Company, National Association: This organization serves as the "custodian," securely holding all loan documents and records.

During the year, Wells Fargo Bank, National Association and Trimont LLC also served as primary servicers for a few specific loans (such as the CX – 250 Water Street Mortgage Loan) for certain periods before their servicing responsibilities were consolidated or transitioned.

Operational Oversight: Servicer Compliance Regulators regularly review Midland Loan Services, a critical manager, to ensure they fulfill their responsibilities correctly. For the fiscal year ending December 31, 2024, Midland Loan Services reported that they complied with all established SEC rules and guidelines for managing loans in these trusts "in all material respects." This means their processes for collecting payments, maintaining records, handling funds, and managing troubled loans are robust and compliant.

Additionally, an independent accounting firm, PricewaterhouseCoopers LLP, reviewed Midland's operations and confirmed their compliance with these rules. This provides assurance that the operational aspects of managing the trust's assets are handled diligently and according to industry standards. It is crucial to remember that this report confirms the quality of the servicing process, not the financial performance of the underlying loans themselves.

Financial Health: Debt, Cash, and Liquidity

The financial health of BBCMS Mortgage Trust 2023-C21 directly depends on the performance and cash flow generated by its underlying commercial mortgage loans.

• Debt: The trust does not take on traditional corporate debt. Instead, it issues classes of commercial mortgage-backed securities (CMBS) to investors, which represent ownership stakes in the pool of mortgage loans. The total outstanding balance of the loans held by the trust, approximately $850 million as of year-end, serves as the primary asset from which investor payments originate.
• Cash Flow: The trust primarily receives cash from scheduled principal and interest payments from borrowers on the mortgage loans. It then uses this cash flow to pay trust expenses and make distributions to the various classes of investors, following the priorities detailed in the pooling and servicing agreement.
• Liquidity: The trust does not maintain substantial cash reserves for operational liquidity beyond what is needed for immediate distributions and trust expense payments. Its ability to meet its obligations to investors (i.e., make timely distributions) relies entirely on the timely receipt of payments from the underlying mortgage loans. Any disruptions in loan payments, such as delinquencies or defaults, directly affect the cash available for distribution and, consequently, the trust's liquidity for its investors.

Future Outlook: Guidance and Strategy

The trust's management team, working through its servicers, actively monitors the portfolio, with a specific focus on loans in challenging sectors and those nearing maturity. Their strategy involves proactive engagement with borrowers, exploring workout options for troubled loans, and ensuring timely payment collection.

While the commercial real estate market faces ongoing uncertainties, especially in the office segment, the portfolio's diversified nature and active management by experienced servicers aim to mitigate potential risks and preserve investor value. The trust will continue to provide updates on portfolio performance and any significant developments in subsequent filings. Ultimately, the trust's outlook is intrinsically linked to broader commercial real estate market conditions and the specific performance of its underlying collateral.

Competitive Position

As a passive investment vehicle created solely to hold a pool of commercial mortgage loans and issue securities backed by their cash flow, BBCMS Mortgage Trust 2023-C21 does not engage in competitive activities or hold a "competitive position" in the market like an operating company. Its performance and standing are instead determined by the quality and performance of its underlying mortgage loan collateral, the structure of its issued securities, and the efficiency of its servicing operations, rather than by market share or competitive strategy.

Understanding these details about BBCMS Mortgage Trust 2023-C21's structure, portfolio performance, and risk factors is key to evaluating its suitability for your investment goals.
