KBRA Downgrades Four Ratings and Affirms Three Ratings for GSMS 2015-GC34
11 Sep 2026 | New York
KBRA downgrades the ratings of four classes of certificates and affirms three ratings for GSMS 2015-GC34, a CMBS conduit transaction. The transaction has been reduced to five assets with an aggregate balance of $217.3 million, from 56 loans totaling $848.4 million at securitization. The ratings actions are based on our identification of all remaining assets as KBRA Loans of Concern (K-LOCs), our estimated losses of $174.1 million (which, if realized, would impact the class B certificates and below) and corresponding recoveries; realized losses totaling $22.6 million, which were allocated to the non-rated class G certificates; and cumulative interest shortfalls of $22.7 million affecting all outstanding certificates.
As of the August 2026 remittance period, all remaining assets in the pool are specially serviced and have been determined to be non-recoverable by the servicer. Among the remaining assets, two (43.3%) are REO. All K-LOCs have estimated losses and are highlighted below.
Illinois Center ($92.1 million, 42.4%, Foreclosure)
- The asset of the trust comprises two adjacent LEED Silver-certified, Class-A office towers containing 2.1 million sf, located in the East Loop submarket of Chicago, Illinois. The two 32-story towers, 111 East Wacker and 233 North Michigan Avenue, are situated on a 3.4-acre site and were originally constructed in 1969 and 1972, respectively.
- The loan transferred to the special servicer in April 2024 due to delinquency. The special servicer initially filed for foreclosure in November 2024 and filed for a summary judgment in May 2026, which went unopposed by the borrower. According to the most recent servicer commentary, parties were waiting for the foreclosure sale judgment to be entered by the court. According to the March 2026 rent roll, the property was 33.0% leased; 111 East Wacker was 49.0% leased and 233 North Michigan was 17.4% leased.
- An updated March 2026 appraisal valued the property at $66.5 million ($32 per sf), which was 82.9% below the $390.0 million ($186 per sf) appraisal value at issuance. The loan was deemed non-recoverable by the servicer in May 2025, and cumulative non-recoverable interest totals $5.6 million for this transaction. Additionally, a total of $5.0 million in non-recoverable servicer advances has been reimbursed by the trust to date. KBRA’s analysis resulted in an estimated loss of $196.5 million (82.0% estimated loss severity) on the aggregate outstanding debt of $239.5 million, of which $75.6 million of the estimated loss is allocated to this transaction. The estimated loss is based on a liquidation value of $63.2 million ($30 per sf) and projected total exposure of $259.7 million. The liquidation value considers a distressed non-stabilized disposition of the asset.
750 Lexington Avenue ($79.9 million, 36.8%, REO)
- The asset of the trust consists of fee and leasehold interests in a 31-story 382,256 sf office property located in the Midtown neighborhood Manhattan, New York. The collateral includes 22,680 sf of ground-floor retail space. A portion of the property is subject to a ground lease that expires in 2041, with three 12-year renewal options remaining. The ground lease rent was previously reset in 2018 and will reset every 12 years thereafter.
- The loan was most recently transferred to the special servicer in October 2023 due to delinquency. A foreclosure action was filed in May 2024, summary judgment was granted in June 2025, and the trust ultimately took title to the asset in March 2026. In May 2024, the property’s largest tenant, WeWork, assumed and amended its lease through the tenant’s bankruptcy proceedings to reduce the lease term, reduce base rent, convert to a gross lease, add revenue sharing, and reduce the tenant’s guaranty. According to the May 2026 rent roll, WeWork is the second-largest tenant by base rent (18.7%) and largest tenant by physical footprint (22.8% of collateral sf) with a lease expiration in February 2029.
- An updated January 2026 appraisal valued the property at $39.0 million ($102 per sf), which was 87.0% below the $300.0 million ($785 per sf) appraisal value at issuance. The asset was deemed non-recoverable by the servicer in March 2024, and cumulative non-recoverable interest totaled $8.9 million. Additionally, a total of $10.8 million of non-recoverable servicer advances has been reimbursed by the trust to date. KBRA’s analysis resulted in an estimated loss of $114.4 million (93.2% estimated loss severity) on the aggregate outstanding balance of $122.9 million, of which $74.4 million of the estimated loss is allocated to this transaction. The estimated loss is based on a liquidation value of $26.6 million ($70 per sf) and projected total exposure of $141.0 million. The liquidation value is based on an income capitalization approach using stabilized KNCF of $3.5 million, a capitalization rate of 9.00%, and a downward adjustment to account for TI/LC costs and income lost during the stabilization period.
Woodlands Corporate Center and 7049 Williams Road Portfolio ($20.7 million, 9.5%, REO)
- The asset of the trust is a portfolio consisting of three office and industrial properties that total 212,032 sf, located within eight miles of each other in the MSA of Buffalo, New York. The properties were constructed between 1999 and 2007.
- The loan transferred to special servicing in December 2019 due to imminent monetary default and the asset became REO in September 2022. Weak financial performance is largely the result of low collateral occupancy. According to the May 2026 rent rolls, the portfolio was 59.7% leased, down from 70.6% at last review and 92.3% at closing. According to the servicer, the assets were not listed for sale as of August 2026.
- A November 2025 appraisal valued the portfolio at $11.4 million ($54 per sf), which is 65.7% below the $33.2% million ($157 per sf) appraisal value at issuance. The asset was determined to be non-recoverable by the servicer in June 2025, and cumulative non-recoverable interest totaled $1.3 million. Additionally, a total of $1.1 million of non-recoverable servicer advances has been reimbursed by the trust to date. KBRA’s analysis resulted in an estimated loss of $15.4 million (74.4% estimated loss severity). The estimated loss is based on a liquidation value of $7.0 million ($33 per sf) and projected total exposure of $22.5 million. The liquidation value is derived from KNCF of $704,000 and a capitalization rate of 10.00%.
The remaining two loans account for 11.3% of the pool balance:
- Bluejay Grocery Portfolio ($17.7 million, 8.2%, Matured Non-Performing) is collateralized by two big-box retail properties that total 128,614 sf and are located in Wisconsin. At issuance, the loan was collateralized by four properties located across three states; however, two properties were sold and released, resulting in principal curtailments from the sales proceeds. One of the remaining properties, located in Madison, was under contract to be sold as of the current review. The loan was deemed non-recoverable in December 2025, and cumulative non-recoverable interest totaled $400,770. KBRA’s analysis resulted in an estimated loss of $6.2 million (35.1% estimated loss severity) based on a liquidation value of $12.2 million ($94 per sf) and projected total exposure of $18.4 million.
- 222 East 59th Street ($6.9 million, 3.2%, Foreclosure) is collateralized by the borrower’s leasehold interest in a six-story 33,995 sf multi-tenant design center and showroom building located in the Plaza District submarket of Manhattan, New York. Built in 2001, the asset was developed as the annex property to the adjacent Decoration & Design Building situated on 979 Third Avenue. The loan transferred to the special servicer in August 2025 for delinquency before defaulting at maturity in October 2025. Foreclosure was filed in March 2026, and a motion to appoint a receiver was filed in May 2026. The property is subject to a ground lease that expires in December 2049. The loan was deemed non-recoverable in January 2026, and cumulative non-recoverable interest totaled $215,200. Additionally, a total of $640,448 of non-recoverable servicer advances has been reimbursed by the trust to date. KBRA’s analysis resulted in an estimated loss of $2.5 million (36.7% estimated loss severity) based on a liquidation value of $4.9 million ($144 per sf) and projected total exposure of $7.4 million.
