On July 7, 2026 (the “Closing Date”), Morgan Stanley Capital I Inc. (the “Registrant”) is expected to cause the issuance of the BANK 2026-BNK52, Commercial Mortgage Pass-Through Certificates, Series 2026-BNK52 (the “Certificates”), pursuant to a Pooling and Servicing Agreement, attached hereto as Exhibit 4.1 and dated as of July 1, 2026 (the “Pooling and Servicing Agreement”), between the Registrant, as depositor, Trimont LLC (“Trimont”), as general master servicer, CWCapital Asset Management LLC, as general special servicer, National Cooperative Bank, N.A., as NCB master servicer and NCB special servicer, Computershare Trust Company, National Association, as certificate administrator, Deutsche Bank National Trust Company, as trustee, and Park Bridge Lender Services LLC, as operating advisor and as asset representations reviewer. Capitalized terms used but not defined herein shall have the meanings assigned to them in the Pooling and Servicing Agreement.

The Certificates will consist of the following classes (each, a “Class”), designated as (i) the Class A-1, Class A-SB, Class A-4, Class A-4-1, Class A-4-2, Class A-4-X1, Class A-4-X2, Class A-5, Class A-5-1, Class A-5-2, Class A-5-X1, Class A-5-X2, Class X-A, Class X-B, Class A-S, Class A-S-1, Class A-S-2, Class A-S-X1, Class A-S-X2, Class B, Class B-1, Class B-2, Class B-X1, Class B-X2, Class C, Class C-1, Class C-2, Class C-X1 and Class C-X2 Certificates (collectively, the “Publicly Offered Certificates”), and (ii) the Class X-D, Class X-E, Class X-F, Class X-G, Class D, Class E, Class F, Class G, Class V and Class R Certificates (collectively, the “Privately Offered Certificates”).

The Publicly Offered Certificates and the Privately Offered Certificates (together with the REMIC regular interests issued pursuant to the Pooling and Servicing Agreement and collectively designated the “VRR Interest”) will represent, in the aggregate, the entire beneficial ownership in the Issuing Entity, a common law trust to be formed on the Closing Date under the laws of the State of New York pursuant to the Pooling and Servicing Agreement. The Issuing Entity’s primary assets will be a pool of 70 commercial, multifamily and/or manufactured housing community mortgage loans (the “Mortgage Loans”). Certain of the Mortgage Loans will be acquired by the Registrant from Morgan Stanley Mortgage Capital Holdings LLC (“MSMCH”) pursuant to a Mortgage Loan Purchase Agreement, attached hereto as Exhibit 99.1 and dated as of June 12, 2026, between the Registrant and MSMCH; certain of the Mortgage Loans will be acquired by the Registrant from JPMorgan Chase Bank, National Association (“JPMCB”) pursuant to a Mortgage Loan Purchase Agreement, attached hereto as Exhibit 99.2 and dated as of June 12, 2026, between the Registrant and JPMCB; certain of the Mortgage Loans will be acquired by the Registrant from National Cooperative Bank, N.A.

The assets of the Issuing Entity will include several Mortgage Loans, each of which is a part of a Whole Loan. Each Whole Loan will be governed by a co-lender, intercreditor or similar agreement (each, an “Intercreditor Agreement”) between the holders of the promissory notes comprising such Whole Loan, the terms of which are described under “Description of the Mortgage Pool—The Whole Loans” in the Prospectus described below. Each Intercreditor Agreement is attached as an exhibit hereto as described in the following table. Moreover, certain of such Whole Loans will not be serviced pursuant to the Pooling and Servicing Agreement but will instead be serviced pursuant to a different servicing agreement (each, a “Non-Serviced PSA”). Each such Non-Serviced PSA is attached as an exhibit hereto as described in the following table. For a description of the servicing of the applicable Whole Loans under such Non-Serviced PSAs, see “Pooling and Servicing Agreement—Servicing of the Non-Serviced Mortgage Loans” in the Prospectus described below.

LLC, J.P. Morgan Securities LLC, Wells Fargo Securities, LLC, BofA Securities, Inc Academy Securities, Inc. and Drexel Hamilton, LLC (collectively, in such capacities, the “Underwriters”), pursuant to an Underwriting Agreement, attached hereto as Exhibit 1.1 and dated as of June 12, 2026, between the Registrant, the Underwriters, as underwriters, and MSMCH, (ii) the sale of the Privately Offered Certificates by the Registrant to Morgan Stanley & Co.
