Item 1. Fundamental Changes

On May 15, 2026, Masterworks Gallery, LLC, as agent for Series 356 ("Series 356") of Masterworks Vault 4, LLC, a Delaware limited liability company (the "Company") and the 356 Segregated Portfolio of Masterworks Cayman, SPC agreed to consign the sole artwork owned by the Company created by Cecily Brown (the "Artwork") to an unaffiliated gallery (the "Consignee"), pursuant to a Consignment Agreement (the "Consignment Agreement"). A copy of the Consignment Agreement is attached to this Form 1-U as Exhibit 6.1.

Pursuant to the Consignment Agreement, the Consignee is appointed as the exclusive selling agent of the Artwork and may sell the Artwork to a third-party through July 25, 2026 (the "Consignment Period"), provided that Company receives a minimum net proceed amount in connection with the sale (the "Floor Price"). The Floor Price, along with any commission and or profit sharing arrangements, were determined based on arm's length negotiations among the parties.

The Consignment Agreement also contains representations, warranties, and covenants of the parties that are customary for transactions of this type. The Artwork will be in the custody of the Consignee during the Consignment Period, and title of the Artwork will continue to be held by the Company unless (i) the Consignee executes a definitive sale of the Artwork and (ii) the Company receives the full amount of its net proceeds from such sale.

Exclusive consignments for a limited duration are a common method of exposing works to a segment of the market, but very often they do not result in a sale transaction. Accordingly, the Company cannot guarantee or express any opinion on the likelihood that a sale of the Artwork will be completed. If the Artwork is sold by the Consignee during the Consignment Period, in accordance with the Company's Amended and Restated Operating Agreement, Series 356 will use the proceeds of the sale of the Artwork to pay or provide for payment of Series 356's liabilities, costs and expenses and will distribute the remaining proceeds of the liquidation of the assets to Series 356's shareholders of record, after which Series 356 will wind up operations and dissolve.
