Here's what we've learned so far:

A Commercial Mortgage-Backed Security (CMBS) trust, like BBCMS Mortgage Trust 2021-C9, operates differently from a regular company. Its annual reports (called 10-Ks) focus on how loans are managed and compliance with specific rules. This structure means the reports emphasize operational details rather than traditional company financial performance or future business plans.

1. What does this trust do and how did its underlying assets perform this year?

First, know this: BBCMS Mortgage Trust 2021-C9 isn't a regular company. You can't buy its stock like Apple or Amazon. Instead, it's a special investment called a 'Mortgage Trust.' This is a Commercial Mortgage-Backed Security, or CMBS. Imagine a big pool of commercial mortgage loans. These are loans to businesses for properties like offices, hotels, or shopping centers. When you 'invest' here, you buy bonds or certificates. These are backed by mortgage payments, not company shares.

Several big financial players set up this trust. They are called 'sponsors' and a 'depositor.' Examples include Barclays Commercial Mortgage Securities LLC and KeyBank National Association. They gathered many commercial mortgage loans. Then they put them into this trust.

For the year ending December 31, 2025, the trust actively managed these mortgage assets. From this report, we learned about some big loans it holds. For example, the trust owns part of the 'Crescent Gateway Mortgage Loan' (4.0% of assets initially). It also holds parts of the 'MGM Grand & Mandalay Bay Mortgage Loan' (around 7.3%) and 'The Atlantic Mortgage Loan' (about 9.4%). It also holds parts of the 'McCarthy Ranch Mortgage Loan' (0.6%) and 'Seaport Homes Mortgage Loan' (1.8%). These percentages show the trust's initial share in these loans. They highlight how certain assets concentrate within the overall pool.

Many of these are 'loan combinations.' Our trust owns a part of the loan. Other trusts or investors hold the remaining parts, called pari passu loans. Payments from these properties split among different investors. Servicing these loans can involve agreements tied to other trusts. For instance, The Atlantic Mortgage Loan is serviced under a different trust's agreement (BBCMS 2021-C10 Transaction). This shows how interconnected these structures are. For investors, one property's performance can impact many CMBS trusts. Servicing decisions for a loan might also be influenced by other certificate holders.

Many companies help manage these loans and the trust. Midland Loan Services acts as master servicer for many loans. It's also the primary servicer for McCarthy Ranch. Midland Loan Services confirmed compliance with all important rules. These are called Regulation AB servicing criteria. An independent auditor, PricewaterhouseCoopers LLP, checked their work and agreed! This covers the year ending December 31, 2025. This means they manage loans by the book. They ensure accurate payment processing, escrow management, and investor reporting. KeyBank National Association is the primary servicer for MGM Grand & Mandalay Bay and The Atlantic loans, among others. Wells Fargo Bank, National Association is the certificate administrator. It also acts as a primary servicer and custodian for several loans. Pentalpha Surveillance LLC advises on some key loans. These servicers are crucial. They collect payments and handle daily mortgage management.

New details on who does what: We learned more about the many companies involved. They keep loans running smoothly. Their roles can be very specialized for individual loans. For instance, Wells Fargo Bank and Wilmington Trust act as "trustees" for different loans. They oversee certain aspects. Other companies also handle specific tasks. U.S. Bank National Association provides custodial services, holding loan documents. CoreLogic Solutions, LLC handles property tax payments. Even Computershare Trust Company, National Association (CTCNA) helps Wells Fargo. It assists with some servicing functions. Sometimes it acts as a "Servicing Function Participant" for the Custodian or Certificate Administrator.

Beyond the main servicers, we see more specialized roles for individual loans. For example, Park Bridge Lender Services LLC advises on the Crescent Gateway loan. It provides oversight and recommendations. Argentic Services Company LP is the 'Special Servicer' for McCarthy Ranch and Seaport Homes Mortgage Loans. This means they step in if these loans face trouble. Situs Holdings, LLC is the Special Servicer for the MGM Grand & Mandalay Bay Mortgage Loan. Rialto Capital Advisors, LLC is the Special Servicer for The Atlantic Mortgage Loan. Trimont LLC also becomes Primary Servicer for the Seaport Homes Mortgage Loan starting March 1, 2025. Different banks like Wells Fargo, Citibank, and U.S. Bank also act as "Custodians." They hold important mortgage documents for specific loans.

Detailed documents lay out these relationships and responsibilities. These include Pooling and Servicing Agreements (PSAs) and Trust and Servicing Agreements (TSAs). Co-Lender Agreements are also included. These are essentially the rulebooks for loan management. They also define how different investors share in them. All these players must report on following the rules. These are called "servicing criteria" under Regulation AB. This ensures correct payment collection and escrow management. This complex web of servicers is typical for CMBS trusts. Their compliance reports are a big part of these annual filings. Strong compliance reports from key servicers, like Midland Loan Services, show good operational management. They indicate underlying assets were managed by established standards throughout 2025.

2. Major wins and challenges this year

The report highlights important points:

• No single big borrower: A positive sign for diversification: "No single borrower represents 10% or more of the pool assets." The trust isn't overly reliant on any one borrower or property. If one borrower struggles or defaults, the impact would spread across many smaller loans, reducing risk for investors.
• Strong Servicing Compliance: Midland Loan Services confirmed compliance with all important servicing rules. This is a big win for the trust's operations. Midland manages many of these loans. This covers Regulation AB for the year ending December 31, 2025. For our trust, BBCMS Mortgage Trust 2021-C9, Midland certified its obligations. It acted as both Master Servicer and Special Servicer throughout 2025. An independent auditor, PricewaterhouseCoopers LLP, checked their work and agreed! This means daily loan management is correct and by the book. This includes collecting payments, managing escrow accounts, and handling reporting. They also took responsibility for other vendors. They confirmed these vendors' compliance for specific tasks. This careful operation is crucial. It maintains the trust's integrity. It also ensures timely payments to certificate holders.
• No major lawsuits: The trust reported no major pending lawsuits. This excludes routine legal matters related to parties' duties. This is good news. Legal battles can be costly and distracting. They could also impact the trust's cash flow or reputation. No significant lawsuits suggest a stable operation.

3. Key risks that could affect the value of the trust's certificates/bonds

The report gives clear insights into the risks:

• No external safety net: It states: "No entity provides external credit enhancement or other support for the certificates." This applies to this transaction. This is critical for investors. No extra guarantees, insurance, or third-party backing exist. These would protect investors if mortgages don't perform as expected. Your investment's value ties directly to commercial mortgage payments. There is no extra protection.
• No derivative support: Similarly, "No entity provides derivative instruments or other support for the certificates." This applies to this transaction. The trust isn't using complex financial tools. These include interest rate swaps or credit default swaps. They would hedge against risks like interest rate changes or boost returns. This keeps the structure simpler. But it means no extra financial engineering exists. This would absorb shocks or reduce specific market risks.

The trust's performance and certificate value rely solely on cash flow. This cash flow comes from commercial mortgage loans. If loans default or payments delay, or property values drop, there's no external buffer. This means no protection for certificate holders. Investors bear the direct risk of these commercial mortgage loans.

4. Leadership or strategy changes

The main Pooling and Servicing Agreement (the trust's rulebook) was amended on October 25, 2024. This indicated K-Star Asset Management LLC would become the overall Special Servicer. K-Star would serve the entire trust, replacing Midland Loan Services.

Midland Loan Services issued a formal compliance statement for the entire calendar year 2025 (dated February 22, 2026). Midland explicitly certified it fulfilled all obligations. It acted as both Master Servicer and Special Servicer for BBCMS Mortgage Trust 2021-C9. This indicates that while K-Star was designated as the new overall Special Servicer in late 2024, Midland continued to be responsible for Special Servicer duties for this specific trust throughout 2025, or for its designated period.

Why does this matter? The Special Servicer acts as the trust's 'troubleshooter'. The Master Servicer handles all regular, performing loans. The Special Servicer steps in when a loan faces trouble. This happens if a borrower misses payments, nears default, or needs a loan modification. They work out these troubled loans. Their goal is to recover as much money as possible for the trust. A change in this role could mean a different approach to problem loans. This might impact trust performance if more loans face difficulties. This is a significant operational change to watch. The Special Servicer's expertise and strategy directly affect recovery rates on defaulted loans.

Also, K-Star was the overall Special Servicer. But some individual mortgage loans within the trust have their own specific Special Servicers. For instance, Argentic Services Company LP is Special Servicer for McCarthy Ranch and Seaport Homes Mortgage Loans. Situs Holdings, LLC serves the MGM Grand & Mandalay Bay Mortgage Loan. Rialto Capital Advisors, LLC is the Special Servicer for The Atlantic Mortgage Loan. This shows a layered approach to managing troubled assets. Some specific loans might have dedicated troubleshooters. This happens even if the main trust has an overarching Special Servicer. This structure allows specialized expertise for particular assets.

When considering an investment in BBCMS Mortgage Trust 2021-C9, focus on the quality and performance of the underlying commercial mortgage loans, the expertise of the servicers, and the specific risks outlined.
