The merger is virtually certain to be approved given Huen's voting control. Existing APM shareholders face massive dilution to 30% ownership in a combined entity with no revenue and a going concern. The stock may trade down toward the implied value of the combined entity. Monitor for any termination of the merger agreement before June 30, 2026, which would likely trigger a termination fee and further downside.

Executive Summary
Aptorum Group filed Pre-Effective Amendment No. 4 to its S-4 registration statement, providing the definitive proxy statement/prospectus for the special meeting on June 9, 2026, to approve the merger with DiamiR Biosciences. The merger will result in existing Aptorum shareholders owning approximately 30% of the combined company, while DiamiR stockholders will own approximately 70%. The filing confirms that CEO Ian Huen, who controls 86.71% of voting power, has already committed to vote in favor of all proposals, making shareholder approval a foregone conclusion. The merger is a condition to Aptorum's continued viability, as the company has a going concern warning, no revenue, and limited cash.
