Citigroup Commercial Mortgage Trust 2016-GC37 Reports Special Servicer Change

What Happened
The registrant filed an 8-K (Item 8.01) reporting that the 79 Madison Avenue mortgage loan—an asset of Citigroup Commercial Mortgage Trust 2016-GC37—has a new special servicer. Effective September 1, 2026, Greystone Servicing Company LLC sold substantially all assets of its special servicing division to C‑IV Asset Management LLC, and C‑IV Asset Management LLC has assumed Greystone’s duties and responsibilities as special servicer under the CGCMT 2016‑P3 pooling and servicing agreement (PSA). An Assignment and Assumption Agreement (Special Servicing), dated September 1, 2026, is filed as Exhibit 20.1 to the report.

Key Details

• Asset: 79 Madison Avenue mortgage loan, part of Citigroup Commercial Mortgage Trust 2016‑GC37.
• Effective date: September 1, 2026.
• Parties: Greystone Servicing Company LLC sold the special servicing division’s assets to C‑IV Asset Management LLC (both Delaware LLCs).

Why It Matters
A change in special servicer affects who handles workout, enforcement, and other problem‑loan decisions for the 79 Madison Avenue mortgage. The filing does not report any change to loan ownership, master servicer, trustee, or certificate administration—only the party responsible for special servicing has changed. Investors should note the new servicer and review the Assignment and Assumption Agreement (Exhibit 20.1) if they want details on the transfer of servicing responsibilities and any related terms.
