Citigroup Commercial Mortgage Trust 2016-P4 Reports Special Servicer Change

What Happened Citigroup Commercial Mortgage Trust 2016-P4 filed an 8-K (Item 8.01) announcing that, effective September 1, 2026, Greystone Servicing Company LLC sold substantially all assets of its special servicing division to C‑IV Asset Management LLC. C‑IV Asset Management LLC has assumed all duties and responsibilities previously held by Greystone as the special servicer under the pooling and servicing agreement (the CGCMT 2016-P3 PSA) that governs servicing of the Marriott Midwest Portfolio mortgage loan. The filing includes an Assignment and Assumption Agreement (Special Servicing) dated September 1, 2026 as Exhibit 20.1.

For investors in the trust, this is primarily an administrative change documented in the servicing agreement; it signals a new firm (C‑IV Asset Management LLC) will carry out special servicing duties previously performed by Greystone. Investors should monitor future filings or notices for any additional material developments about the loan’s performance or cash flows.
