Item 9. Other Events

The Class A shares of each series of Masterworks Vault 5, LLC (the "Company") that have been outstanding for 90 days (the "Shares") are currently eligible to trade on the "PPEX ATS", an alternative trading system registered with the U.S. Securities and Exchange Commission and operated by North Capital Private Securities Corporation ("North Capital").

On June 17, 2026, Masterworks delivered written notice to North Capital terminating the agreements pursuant to which secondary trading in the Shares is facilitated on the PPEX ATS, effective on or about December 14, 2026 (the "ATS Termination Date").

Following the ATS Termination Date, the Shares will no longer be available for trading on the PPEX ATS, and holders will not be able to buy or sell Shares through that venue. The Company currently intends to arrange for an alternative means of secondary liquidity for holders of the Shares following the ATS Termination Date, which may take the form of a bulletin board, a matching service, or another trading or liquidity mechanism.

However, no assurance can be given that the Company will implement any such alternative, that any such alternative will be available on or after the ATS Termination Date, or that any such alternative, if implemented, will provide liquidity comparable to that historically available through the PPEX ATS, or any liquidity at all.

There is no established public trading market for the Shares, and the Shares are illiquid. Following the ATS Termination Date, holders may be unable to sell their Shares at the time they wish to do so, at a price they consider acceptable, or at all, and should be prepared to hold their Shares for an indefinite period. The Company will provide additional information regarding any alternative liquidity arrangements as and when such information becomes available.
