The Securities May Not Be a Suitable Investment for You

The securities offered by this Term Sheet are not suitable investments for all investors. In particular, you should not purchase any class of securities unless you understand and are able to bear the prepayment, credit, liquidity and market risks associated with that class of securities. For those reasons and for the reasons set forth under the headings “Summary of Risk Factors” and “Risk Factors” in the Preliminary Prospectus, the yield to maturity of, the aggregate amount and timing of distributions on and the market value of the offered securities are subject to material variability from period to period and give rise to the potential for significant loss over the life of those securities. The interaction of these factors and their effects are impossible to predict and are likely to change from time to time. As a result, an investment in the offered securities involves substantial risks and uncertainties and should be considered only by sophisticated institutional investors with substantial investment experience with similar types of securities and who have conducted appropriate due diligence on the mortgage loans and the securities. Potential investors are advised and encouraged to review the Preliminary Prospectus in full and to consult with their legal, tax, accounting and other advisors prior to making any investment in the offered securities described in this Term Sheet.

Allocation Between
Combined VRR Interest
and Non-Vertically
Retained

The “Vertically Retained Percentage” is a fraction, expressed as a percentage, the numerator of which is the initial principal balance of the Combined VRR Interest, and the denominator of which is the sum of (x) the aggregate initial certificate balance of all classes of Non-Vertically Retained Principal Balance Certificates and (y) the initial principal balance of the Combined VRR Interest.

The “Non-Vertically Retained Percentage” is the difference between 100% and the Vertically Retained Percentage.

any unreimbursed losses on the mortgage loans that were previously allocated to reduce the certificate balance of that class, together with interest at its pass-through rate.

Prepayment Premiums

and Yield Maintenance

If a prepayment premium (calculated as a percentage of the amount prepaid) is imposed in connection with a prepayment rather than a yield maintenance charge, then the prepayment premium so collected will be allocated as described above. For this purpose, the discount rate used to calculate the Base Interest Fraction will be the discount rate used to determine the yield maintenance charge for mortgage loans that require payment at the greater of a yield maintenance charge or a minimum amount equal to a fixed percentage of the principal balance of the mortgage loan or, for mortgage loans that only have a prepayment premium based on a fixed percentage of the principal balance of the mortgage loan, such other discount rate as may be specified in the related loan documents.

After the notional amounts of the Class X-A, Class X-B and Class X-D certificates and the certificate balances of the Class A-1, Class A-4, Class A-5, Class A-SB, Class A-S, Class B, Class C and Class D certificates have been reduced to zero, the Non-Vertically Retained Percentage of all prepayment premiums and yield maintenance charges with respect to the mortgage loans will be allocated to the holders of the Class E, Class F and Class G-RR certificates as provided in the Benchmark 2026-B43 pooling and servicing agreement. No yield maintenance charges or prepayment premiums will be distributed to the holders of the Class X-E, Class X-F and Class R certificates. For a description of prepayment premiums and yield maintenance charges required on the mortgage loans, see Annex A to the Preliminary Prospectus. See also “Certain Legal Aspects of the Mortgage Loans—Default Interest and Limitations on Prepayments” in the Preliminary Prospectus.

any advances, provided that, in an urgent or emergency situation requiring the making of a property protection advance, the special servicer may, in its sole discretion, make a property protection advance and will be entitled to reimbursement from the master servicer for such advance. The master servicer, the special servicer and the back-up advancing agent will each be entitled to receive interest on advances they make at the prime rate (and, solely with respect to the master servicer, subject to a floor rate of 2.0% per annum), compounded annually.

Serviced Mortgage

One or more whole loans may be identified in the Preliminary Prospectus as a “servicing shift whole loan”, in which case the related mortgage loan constitutes a “servicing shift mortgage loan” and each related companion loan constitutes a “servicing shift companion loan”. Any servicing shift whole loan will initially be serviced pursuant to the Benchmark 2026-B43 pooling and servicing agreement during which time such mortgage loan, such whole loan and each related companion loan will be a serviced mortgage loan, a serviced whole loan and a serviced companion loan (each as defined below), respectively. However, upon the inclusion of the related controlling pari passu companion loan in a future securitization transaction, the servicing of such mortgage loan will shift to the servicing agreement governing such securitization transaction, and such mortgage loan, such whole loan and each related companion loan will be an outside serviced mortgage loan, an outside serviced whole loan and an outside serviced companion loan, respectively.

All of the mortgage loans transferred to the issuing entity (other than any outside serviced mortgage loan) are sometimes referred to in this Term Sheet as the “serviced mortgage loans” and, together with any related companion loans, as the “serviced loans” (which signifies that they are being serviced by the master servicer and the special servicer under the Benchmark 2026-B43 pooling and servicing agreement); each related whole loan constitutes a “serviced whole loan”; and each related companion loan constitutes a “serviced companion loan.” See “Description of the Mortgage Pool—The Whole Loans” in the Preliminary Prospectus.

Appraisal Reduction

For purposes of determining the identity of the Controlling Class and the existence of a Control Termination Event or an Operating Advisor Consultation Trigger Event, as well as the allocation and/or exercise of voting rights for certain purposes, the Non-Vertically Retained Percentage of any Appraisal Reduction Amounts in respect of or allocated to the mortgage loans will be allocated to notionally reduce the certificate balances of the Non-Vertically Retained Principal Balance Certificates as follows: first, to the Class G-RR, Class F, Class E, Class D, Class C, Class B and Class A-S certificates, in that order, in each case until the related certificate balance is notionally reduced to zero; and then to the Class A-1, Class A-4, Class A-5 and Class A-SB certificates, pro rata based on certificate balance.

Cumulative Appraisal

“Collateral Deficiency Amount” means, with respect to any AB Modified Loan as of any date of determination, the excess of (i) the stated principal balance of such AB Modified Loan (taking into account the related junior note(s) included therein), over (ii) the sum of (in the case of a whole loan, solely to the extent allocable to the subject mortgage loan) (x) the most recent appraised value for the related mortgaged property or mortgaged properties, plus (y) solely to the extent not reflected or taken into account in such appraised value and to the extent on deposit with, or otherwise under the control of, the lender as of the date of such determination, any capital or additional collateral contributed by the related borrower at the time the mortgage loan, became (and as part of the modification related to) such AB Modified Loan for the benefit of the related mortgaged property or mortgaged properties (provided, that in the case of an outside serviced mortgage loan, the amounts set forth in this clause (y) will be taken into account solely to the extent relevant information is received), plus (z) any other escrows or reserves (in addition to any amounts set forth in the immediately preceding clause (y)) held by the lender in respect of such AB Modified Loan as of the date of such determination. For purposes of determining the identity of the Controlling Class and the existence of a Control Termination Event or an Operating Advisor Consultation Trigger Event, the Non-Vertically Retained Percentage of any Collateral Deficiency Amounts will be allocable to the respective classes of Control Eligible Certificates (as defined below) (or for purposes of determining an Operating Advisor Consultation Trigger Event, the HRR Certificates), in reverse alphabetical order of class designation, in a manner similar to the allocation of Appraisal Reduction Amounts to such classes.

“AB Modified Loan” means any mortgage loan (1) that became a corrected loan (which includes for purposes of this definition any outside serviced mortgage loan that became a “corrected” mortgage loan (or any term substantially similar thereto) pursuant to the related outside servicing agreement) due to a modification thereto that resulted in the creation of an A/B note structure (or similar structure) and as to which the new junior note(s) did not previously exist or the principal amount of the new junior note(s) was previously part of either an A note held by the trust or the original unmodified mortgage loan and (2) as to which an Appraisal Reduction Amount is not in effect.

provided, that with respect to any serviced whole loan, the rights of the Directing Holder will be subject to and may be limited by the terms and provisions of any related co-lender agreement.

The applicable directing holder (or equivalent party) with respect to any outside serviced mortgage loan will be, in general, (i) in the event the related Controlling Note is included in the subject outside securitization transaction, the controlling class representative (or equivalent entity) under the related outside servicing agreement, and (ii) in all other cases, the third party holder of the related Controlling Note or its representative (which may be a controlling class representative (or equivalent entity) under a separate securitization transaction to which such note has been transferred (if any)), as provided in the related co-lender agreement.

An “excluded mortgage loan” is a mortgage loan or whole loan with respect to which the Controlling Class Representative or the holder(s) of more than 50% of the Controlling Class (by certificate balance) is (or are) a Borrower Party (as defined in the Preliminary Prospectus).

Controlling Class

On the Closing Date, (i) BREC Securities Holdings, LLC, a Delaware limited liability company, or an affiliate, is expected to purchase each Class of the HRR Certificates, and (ii) BREC Securities Holdings, LLC, a Delaware limited liability company, will appoint itself or an affiliate as the initial Controlling Class Representative. BREC Securities Holdings LLC, a Delaware limited liability company or one of its affiliates may purchase additional Certificates.

Control Termination

The holders of Certificates representing the majority of the certificate balance of the most senior class of Control Eligible Certificates whose certificate balance is notionally reduced to less than 25% of the initial certificate balance of that class as a result of an allocation of an Appraisal Reduction Amount or a Collateral Deficiency Amount, as applicable, to such class will have the right to challenge the Special Servicer’s Appraisal Reduction Amount determination or a Collateral Deficiency Amount determination, as applicable, and, at their sole expense, obtain a second appraisal for any serviced loan for which an Appraisal Reduction Event has occurred or as to which there exists a Collateral Deficiency Amount, under the circumstances described in the Preliminary Prospectus.

Consultation Termination

Control/Consultation

After the occurrence and during the continuance of a Control Termination Event, the consent rights of the Controlling Class Representative with respect to the applicable serviced loans will terminate, and the Controlling Class Representative will retain non-binding consultation rights under the Benchmark 2026-B43 pooling and servicing agreement with respect to certain major decisions and other matters with respect to the serviced mortgage loans, other than (i) any excluded mortgage loan, and (ii) any serviced outside controlled whole loan.

After the occurrence and during the continuance of a Consultation Termination Event, all of these rights of the Controlling Class Representative with respect to the applicable serviced loans will terminate.

With respect to any serviced outside controlled whole loan (including any servicing shift whole loan for so long as it is serviced under the Benchmark 2026-B43 pooling and servicing agreement), the holder of the related Controlling Note or its representative (which holder or representative will not be the Controlling Class Representative) will instead be entitled to exercise the above-described consent and consultation rights, to the extent provided under the related co-lender agreement.

With respect to each outside serviced whole loan, the applicable outside controlling class representative or other related controlling noteholder pursuant to, and subject to the limitations set forth in, the related outside servicing agreement and the related co-lender agreement will have consent, consultation, approval and direction rights with respect to certain major decisions (including with respect to assumptions, waivers, loan modifications and workouts) regarding such outside serviced whole loan, as provided for in the related co-lender agreement and in the related outside servicing agreement. To the extent permitted under the related co-lender agreement, the Controlling Class Representative (so long as a Consultation Termination Event does not exist) may have certain consultation rights with respect to each outside serviced whole loan.

See “Description of the Mortgage Pool—The Whole Loans” in the Preliminary Prospectus.

Risk Retention

With respect to any risk retention consultation party, an “excluded RRCP mortgage loan” is a mortgage loan or whole loan with respect to which such risk retention consultation party, or the person(s) entitled to appoint such risk retention consultation party, is a Borrower Party.

Termination of

Except in the case of a serviced outside controlled whole loan, and solely if a Control Termination Event has occurred and is continuing, the special servicer under the Benchmark 2026-B43 pooling and servicing agreement may be terminated and replaced pursuant to a vote of applicable certificateholders, with or without cause, in accordance with the procedures described under “The Pooling and Servicing Agreement—Removal of the Special Servicer by Certificateholders Following a Control Termination Event” in the Preliminary Prospectus, upon the affirmative vote of (a) the holders of Certificates evidencing at least 66-2/3% of the voting rights allocable to the Certificates of those holders that voted on such matter (provided that holders representing the applicable Certificateholder Quorum vote on the matter) or (b) the holders of Non-Reduced Certificates entitled to vote on the matter evidencing more than 50% of the voting rights allocable to each class of such Non-Reduced Certificates.

At any time, the special servicer under the Benchmark 2026-B43 pooling and servicing agreement may be terminated and replaced with respect to all the serviced loans, if (i) the operating advisor (A) determines, in its sole discretion exercised in good faith, that the special servicer has failed to comply with the Servicing Standard and a replacement of the special servicer would be in the best interest of the holders of the Certificates and the Uncertificated VRR Interest owners (as a collective whole), and (B) recommends the replacement of the special servicer with respect to such serviced loans, and (ii) the holders of Certificates evidencing at least a majority of the aggregate outstanding principal balance of the Certificates of those holders that voted on the matter (provided that holders representing the applicable Certificateholder Quorum vote on the matter) affirmatively vote to remove the special servicer in such capacity in accordance with the procedures set forth under “The Pooling and Servicing Agreement—Removal of the Special Servicer by Certificateholders Based on the Recommendation of the Operating Advisor” in the Preliminary Prospectus.

“Non-Reduced Certificates” means each class of Principal Balance Certificates that has an outstanding certificate balance as may be notionally reduced by any Appraisal Reduction Amounts allocated to that class, equal to or greater than 25% of an amount equal to the initial certificate balance of that class of certificates minus all principal payments made on such class of certificates.

Notwithstanding the foregoing, but subject to the discussion in the next paragraph, solely with respect to a serviced outside controlled whole loan (including any servicing shift whole loan, for so long as it is serviced pursuant to the Benchmark 2026-B43 pooling and servicing agreement), only the holder of the related Controlling Note or its representative may terminate the special servicer without cause (solely with respect to the related whole loan) and appoint a replacement special servicer for that whole loan.

“Certificateholder Quorum” means a quorum that: (a) for purposes of a vote to terminate and replace the special servicer or the asset representations reviewer at the request of the holders of Certificates evidencing not less than 25% of the voting rights (without regard to the application of any Appraisal Reduction Amounts), consists of the holders of Certificates evidencing at least 50% of the voting rights (taking into account the allocation of any Appraisal Reduction Amounts to notionally reduce the certificate balances of the respective classes of Principal Balance Certificates) of all of the Certificates, on an aggregate basis; and (b) for purposes of a vote to terminate and replace the special servicer based on a recommendation of the operating advisor, consists of the holders or beneficial owners of Certificates evidencing at least

20% of the aggregate outstanding principal balance of all the Principal Balance Certificates, with such quorum including at least three Certificateholders or Certificate Owners that are not Risk Retention Affiliated with each other.

The related outside special servicer under each outside servicing agreement generally may be (or, if the applicable outside servicing agreement has not yet been executed, it is anticipated that such outside special servicer may be) replaced by the related outside controlling class representative (or an equivalent party), or the vote of the requisite holders of certificates issued, under the applicable outside servicing agreement (depending on whether or not the equivalent of a control termination event or a consultation termination event exists under that outside servicing agreement) or by any applicable other controlling noteholder under the related co-lender agreement in a manner generally similar to the manner in which the special servicer may be replaced under the Benchmark 2026-B43 pooling and servicing agreement as described above in this “Termination of Special Servicer” section (although there will be differences, in particular as regards certificateholder votes and the timing of when an outside special servicer may be terminated based on the recommendation of an operating advisor).

If the special servicer, to its knowledge, becomes a Borrower Party with respect to a mortgage loan, the special servicer will not be permitted to act as special servicer with respect to that mortgage loan. Subject to certain limitations described in the Preliminary Prospectus, any applicable Directing Holder will be entitled to appoint a replacement special servicer for that mortgage loan. If there is no applicable Directing Holder or if the applicable Directing Holder does not take action to appoint a replacement special servicer within the requisite time period, a replacement special servicer will be appointed in the manner specified in the Benchmark 2026-B43 pooling and servicing agreement.

provided, that in certain circumstances described under “The Pooling and Servicing Agreement” in the Preliminary Prospectus, voting rights will only be exercisable by holders of the Non-Reduced Certificates and/or may otherwise be exercisable or allocated in a manner that takes into account the allocation of Appraisal Reduction Amounts.

The voting rights of any class of Certificates are required to be allocated among certificateholders of such class in proportion to their respective percentage interests.

The Class R certificates and the Uncertificated VRR Interest will not be entitled to any voting rights.

Servicing

All excess modification fees earned by the special servicer will be required to offset any future workout fees or liquidation fees payable with respect to the related serviced mortgage loan or related REO property; provided, that if the serviced mortgage loan ceases being a corrected loan, and is subject to a subsequent modification, any excess modification fees earned by the special servicer prior to such serviced mortgage loan ceasing to be a corrected loan will no longer be offset against future liquidation fees and workout fees unless such serviced mortgage loan ceased to be a corrected loan within 18 months of it becoming a modified mortgage loan.

Penalty Fees: All late fees and default interest will first be used to reimburse certain expenses previously incurred with respect to the related mortgage loan (including special servicing fees, workout fees and liquidation fees) but not yet reimbursed to the trust, the master servicer or the special servicer or to pay certain expenses (including special servicing fees, workout fees and liquidation fees) that are still outstanding on the related mortgage loan, and any excess received with respect to a serviced loan will be paid to the master servicer (for penalty fees accrued while a non-specially serviced loan) and the special servicer (for penalty fees accrued while a specially serviced loan). To the extent any amounts reimbursed out of penalty charges are subsequently recovered on a related serviced loan, they will be paid to the master

servicer or special servicer who would have been entitled to the related penalty charges that were previously used to reimburse such expense.

Liquidation / Workout Fees: Liquidation fees will be calculated at the lesser of (a) 1.0% or (b) with respect to any serviced mortgage loan (or related serviced whole loan, if applicable) or related REO Property, such lesser rate as would result in a liquidation fee of $1,000,000, for each serviced loan that is a specially serviced loan and any REO property, subject in any case to a minimum liquidation fee of $25,000. For any serviced loan that is a corrected loan, workout fees will be calculated at the lesser of (a) 1.0% and (b) such lower rate as would result in a workout fee of $1,000,000 when applied to each expected payment of principal and interest (other than (i) default interest and (ii) any “excess interest” accrued after the related anticipated repayment date on any mortgage loan with an anticipated repayment date) on the related serviced loan (or related serviced whole loan, if applicable) from the date such serviced loan becomes a corrected loan through and including the then related maturity date, subject in any case to a minimum workout fee of $25,000.

Notwithstanding the foregoing, in connection with a maturity default, no liquidation or workout fee will be payable in connection with a payoff or refinancing of the related serviced loan within 90 days of the maturity default, but the special servicer may collect from the related borrower and retain (x) a liquidation fee or workout fee, as applicable, and (y) such other fees as are provided for in the related loan documents.

In the case of an outside serviced whole loan, calculation of the foregoing amounts payable to the related outside servicer or outside special servicer may be different than as described above. For example, the extent to which modification fees and penalty fees are applied to offset expenses may be different and liquidation fees and workout fees may be subject to different caps or no caps.

An “Operating Advisor Consultation Trigger Event” will occur when the aggregate outstanding certificate balance of the HRR Certificates (as notionally reduced by any Cumulative Appraisal Reduction Amounts then allocable to the HRR Certificates) is 25% or less of the initial aggregate certificate balance of the HRR Certificates. With respect to excluded mortgage loans, an Operating Advisor Consultation Trigger Event will be deemed to exist.

Notwithstanding the foregoing, the operating advisor will generally have no obligations or consultation rights as operating advisor under the Benchmark 2026-B43 pooling and servicing agreement with respect to any outside serviced mortgage loan or any related REO property.

The operating advisor will be subject to termination and replacement if the holders of at least 15% of the voting rights of Non-Reduced Certificates vote to terminate and replace the operating advisor and such termination and replacement is affirmatively voted for by the holders of more than 50% of the voting rights allocable to the Non-Reduced Certificates of those holders that exercise their right to vote (provided that holders entitled to exercise at least 50% of the voting rights allocable to the Non-Reduced Certificates exercise their right to vote within 180 days of the initial request for a vote). The holders initiating such vote will be responsible for the fees and expenses in connection with the vote and replacement.

See “The Pooling and Servicing Agreement—Operating Advisor” in the Preliminary Prospectus.

Asset Representations

delinquent in respect of their related monthly payments or balloon payment, if any (for purposes of this paragraph, “delinquent loans”) or (2) at least 15 mortgage loans are delinquent loans as of the end of the applicable collection period and the aggregate outstanding principal balance of such delinquent loans constitutes at least 20% of the aggregate outstanding principal balance of all of the mortgage loans (including any REO mortgage loans) held by the issuing entity as of the end of the applicable collection period.

The asset representations reviewer may be terminated and replaced without cause. Upon (i) the written direction of holders of the Certificates (other than the Class R certificates) evidencing not less than 25% of the voting rights requesting a vote to terminate and replace the asset representations reviewer with a proposed successor asset representations reviewer that is an eligible asset representations reviewer, and (ii) payment by such holders to the certificate administrator of the reasonable fees and expenses to be incurred by the certificate administrator in connection with administering such vote, the certificate administrator will promptly provide notice of such request to all certificateholders and the asset representations reviewer by posting such notice on its internet website, and by mailing such notice to all certificateholders and the asset representations reviewer. Upon the affirmative vote of the holders of Certificates evidencing at least 75% of the voting rights allocable to those holders that exercise their right to vote (provided that holders representing the applicable Certificateholder Quorum exercise their right to vote within 180 days of the initial request for a vote), the trustee will be required to terminate all of the rights and obligations of the asset representations reviewer under the Benchmark 2026-B43 pooling and servicing agreement by written notice to the asset representations reviewer, and the proposed successor asset representations reviewer will be appointed. See “The Pooling and Servicing Agreement—The Asset Representations Reviewer” in the Preliminary Prospectus.

Dispute Resolution

Generally, in the event that a Repurchase Request (as defined in the Preliminary Prospectus) with respect to a mortgage loan is not “Resolved” (as defined below) within 180 days after the related mortgage loan seller receives such Repurchase Request, then the enforcing servicer will be required to send a notice to the “Initial Requesting Certificateholder” (if any) indicating the enforcing servicer’s intended course of action with respect to the Repurchase Request. If (a) the enforcing servicer’s intended course of action with respect to the Repurchase Request does not involve pursuing further action to exercise rights against the applicable mortgage loan seller with respect to the Repurchase Request and the Initial Requesting Certificateholder, if any, or any other holder or beneficial owner of Certificates (other than a holder of the Class VRR certificates) wishes to exercise its right to refer the matter to mediation (including nonbinding arbitration) or arbitration, or (b) the enforcing servicer’s intended course of action is to pursue further action to exercise rights against the related mortgage loan seller with respect to the Repurchase Request but the Initial Requesting Certificateholder, if any, or any other holder or beneficial owner of Certificates (other than a holder of Class VRR certificates) does not agree with the dispute resolution method selected by the enforcing servicer, then the Initial Requesting Certificateholder, if any, or such other holder or beneficial owner of Certificates (other than a holder of Class VRR certificates) may deliver a written notice to the enforcing servicer indicating its intent to exercise its right to refer the matter to either mediation or arbitration. In addition, any other holder or beneficial owner of Certificates may deliver, within the time frame provided in the Benchmark 2026-B43 pooling and servicing agreement, a written notice requesting the right to participate in any dispute resolution consultation that is conducted by the enforcing servicer following the enforcing servicer’s receipt of the notice described in the preceding sentence.

“Resolved” means, with respect to a Repurchase Request in connection with a mortgage loan, (i) that any material breach of representations and warranties or a material document defect has been cured, (ii) the related mortgage loan has been repurchased in accordance with the related mortgage loan purchase agreement, (iii) a mortgage loan has been substituted for the related mortgage loan in accordance with the related mortgage loan purchase agreement, (iv) the applicable mortgage loan seller has made a “loss of value payment”, (v) a contractually binding agreement has been entered into between the enforcing servicer, on behalf of the issuing entity, and the related mortgage loan seller that settles the related mortgage loan seller’s obligations under the related mortgage loan purchase agreement, or (vi) the related mortgage loan is no longer property of the issuing entity as a result of a sale or other disposition in accordance with the Benchmark 2026-B43 pooling and servicing agreement.

The Loan.  The largest mortgage loan (the “NOVA Retail 2-Pack Mortgage Loan”) is part of a whole loan (the “NOVA Retail 2-Pack Whole Loan”) which is comprised of eight pari passu promissory notes with an aggregate outstanding principal balance as of the Cut-off Date of $165,000,000. The NOVA Retail 2-Pack Whole Loan is secured by the borrowers’ fee simple interest in two grocery-anchored retail centers located in Virginia, totaling 840,643 SF (the “NOVA Retail 2-Pack Portfolio”). The NOVA Retail 2-Pack Whole Loan was co-originated on February 20, 2026 by Goldman Sachs Bank USA (“GSBI”) and JPMorgan Chase Bank, National Association (“JPMCB”). The NOVA Retail 2-Pack Mortgage Loan is evidenced by the non-controlling Notes A-3-1, A-4, A-5, and A-6 contributed by GSBI’s affiliate, Goldman Sachs Mortgage Company, with an original principal balance of $67,000,000. The NOVA Retail 2-Pack Whole Loan has a ten-year term, is interest-only for the full term and accrues interest at a rate of 6.09300% per annum on an Actual/360 basis. The scheduled maturity date of the NOVA Retail 2-Pack Whole Loan is March 1, 2036.

The relationship between the holders of the NOVA Retail 2-Pack Whole Loan is governed by a co-lender agreement as described under “Description of the Mortgage Pool—The Whole Loans—The Outside Serviced Pari Passu Whole Loans” in the Preliminary Prospectus. The NOVA Retail 2-Pack Whole Loan will be serviced pursuant to the pooling and servicing agreement for the WFCM 2026-C66 securitization trust. See “The Pooling and Servicing Agreement—Servicing of the Outside Serviced Mortgage Loans” in the Preliminary Prospectus.

The Properties. The NOVA Retail 2-Pack Portfolio consists of a 437,273 SF anchored retail center located in Alexandria, Virginia (the “Plaza at Landmark Property”) and a 403,370 SF anchored retail center located in Fairfax, Virginia (the “Fair City Mall Property”). The NOVA Retail 2-Pack Portfolio was most recently renovated in 2020, which included general infrastructure upgrades, tenant space improvements and landscaping. According to the appraisals, both the Plaza at Landmark Property and the Fair City Mall Property are located in affluent, high-growth submarkets with nearby access to I-495, I-395 and major regional employment centers. The NOVA Retail 2-Pack Portfolio is served by public transit and are proximate to major residential neighborhoods and demand generators, including George Mason University and Inova Alexandria Hospital.
