**Comment for Type of Reporting Person:** (1) The number reported in Rows 5, 7 and 9 represents an aggregate of 10,788,390 ordinary shares of Epsium Enterprise Limited (the "Issuer"), consisting of (i) 14,390 Class A ordinary shares and (ii) 10,774,000 Class B ordinary shares, each with a par value of $0.00002 per share (collectively, the "Ordinary Shares"). On August 22, 2025, pursuant to shareholder resolutions, the Issuer re-designated its share capital into Class A and Class B Ordinary Shares. Mr. Tam exchanged 10,800,000 Class A ordinary shares for an equal number of Class B ordinary shares. Each Class B ordinary share shall be convertible into Class A ordinary share at any time on a one-for-one basis at the option of the holder thereof. Class A ordinary shares shall not be convertible into Class B ordinary shares under any circumstances. On September 30, 2025, Mr. Tam converted 26,000 Class B ordinary shares into 26,000 Class A ordinary shares. On the same date, Mr. Tam filed a Form 144 in connection with the removal of restrictions on certain Class A ordinary shares.

(2) The percentage reported in Row 11 is based on 13,438,034 Ordinary Shares outstanding as of April 21, 2026, being the sum of (i) 2,664,034 Class A ordinary shares, and (ii) 10,774,000 Class B ordinary shares, as provided by the Issuer.

(3) The percentage of voting power, 98.79%, is calculated by dividing the voting power beneficially owned by the reporting person by the voting power beneficially owned by all of the Issuer's holders of Class A ordinary shares and Class B ordinary shares as a single class as of April 21, 2026. Each Class A ordinary share is entitled to one vote per share, and each Class B ordinary share is entitled to twenty votes per share.
