On
May 31, 2026, VSee Health, Inc., a Delaware corporation (the “Company”) entered into a Stock Purchase Agreement (the “Purchase
Agreement”) with Milton Chen, the Company’s co-Chief Executive Officer and Chairman of the Board and the Chief Executive
Officer of VSee Lab, Inc., a Delaware Corporation and wholly-owned subsidiary of the Company (“VSee Lab”). Pursuant to the
Purchase Agreement, Mr. Chen agreed to purchase, and the Company agreed to sell to Mr. Chen, on the May 31, 2026 (the “Closing
Date”), all of the equity securities of VSee Lab (the “VSee Lab Stock”), free and clear of all liens and encumbrances.
Under the Purchase Agreement, Mr. Chen is solely responsible for causing the Company to satisfy any and all indebtedness and other liabilities
of VSee Lab that are not paid as of the closing contemplated by the Purchase Agreement (the “Closing”) and the Company will
have no obligation with respect thereto. Notwithstanding, the Company will retain, pay, perform and discharge and remain solely responsible
for, any and all liabilities, obligations or commitments of VSee Lab or relating to the ownership or operation of VSee Lab related to
any period, event, circumstance or condition occurring prior to the Closing Date, including any liabilities relating to taxes for any
and all taxes attributable to any taxable period ending on or before the Closing Date and the portion through the Closing Date for any
taxable period that includes, but does not end, on the Closing Date, other than sales and use taxes accrued at the company level, which
will remain an obligation of VSee Lab, regardless of the time period of when such obligation were incurred and except to the extent expressly
assumed by Mr. Chen pursuant to the Purchase Agreement.
In
consideration for the VSee Lab Stock and the mutual release of liability set forth in the Purchase Agreement, Mr. Chen has agreed to
transfer to the Company all of the common stock, par value $0.0001 per share (the “Common Stock”), of the Company that he
currently owns, or 2,870,069 shares of Common Stock. In connection with the execution of the Purchase Agreement, Mr. Chen resigned as
co-Chief Executive Officer and chairman of the board of directors of the Company, effective as of the Closing Date.
