Item 7. Departure of Certain Officers

On September 1, 2026, Nigel Glenday resigned as Chief Executive Officer, Chief Financial Officer and a manager of the Company, and he also resigned from all other officer, manager and director positions held with other affiliates of Masterworks, effective as of 11:59 p.m. Eastern time on that date (the “Transition Date”). Mr. Glenday’s resignation was not the result of any disagreement with the Company, Masterworks, or their respective affiliates on any matter relating to the Company’s operations, policies, or practices.

Effective simultaneously with, and so as to avoid any vacancy resulting from, Mr. Glenday’s resignation, Scott Lynn was appointed to fill all roles vacated by Mr. Glenday, including serving as Chief Executive Officer, Chief Financial Officer, and as a manager of the Company. Mr. Lynn is the founder and Chief Executive Officer of Masterworks, LLC, the parent company that owns the Masterworks investment platform. There is no arrangement or understanding between Mr. Lynn and any other person pursuant to which Mr. Lynn was appointed to these positions, other than as described in this Item 7.

Following the Transition Date, it is expected that Mr. Glenday will continue to serve as a senior adviser to Masterworks, LLC and its affiliates.
