**Item 6.04 Failure to Make a Required Distribution.**

The Certificate Administrator made distributions to the Certificateholders on the February 18, 2026 Distribution Date. The Certificate Administrator was subsequently notified by the Master Servicer on March 2, 2026 of a payment revision to the Class D, Class E, Class F and Class G Certificateholders. The payment revision was due to the special servicer providing updated reporting regarding the release of $55,300,000 in funds previously withheld in relation to certain litigation matters. This resulted in an additional principal payment to the Class D Certificateholders in an amount equal to $3,712.50, an additional interest payment to the Class D Certificateholders in an amount equal to $118,790.27, an additional interest payment to the Class E Certificateholders in an amount equal to $19,356,149.13, an additional interest payment to the Class F Certificateholders in an amount equal to $9,672,108.34 and an additional interest payment to the Class G Certificateholders in an amount equal to $25,149,239.76. The additional payments were made to the impacted Certificateholders on March 3, 2026. An additional $1,000,000 is being withheld from the released funds by the Certificate Administrator for anticipated future litigation expenses.
