 pursuant to the Disposition that were also taxed under the PFIC rules. The Proposed Regulations also provide rules intended to coordinate the PFIC rules with the rules of Code section 367(b), discussed above under “Effect of Section 367 on the Domestication for U.S. Holders of Aptorum Shares”. Under these coordinating rules, if the gain recognition rule of the Proposed Regulations applied to a disposition of PFIC stock that was also subject to the rules of Section 367(b) — because the foreign corporation had an all earnings and profit amount — the gain realized on the transfer would first be taxable under Section 1291(f) and any gain not taxable under Section 1291(f) would then be taxable as provided under Section 367(b). As with distributions pursuant to the Disposition, The foregoing tax effects of PFIC status on the Domestication would be different if any U.S. Holder has, during his ownership of Aptorum shares, made an election (a so -called“mark -to-market” election) to include in income for each of the years that he has owned his Aptorum shares an amount of income representing the increase in the value of his shares during the year. Any U.S. Holder who has made such an election should consult with his own tax advisor about the tax ramifications of having done so. Aptorum intends to take the position that it is not and has never been a PFIC with respect to any U.S. Holder but cannot provide any assurances that its position will be upheld. The PFIC rules are complex and are affected by various factors in addition to those described above. Accordingly, U.S. holders of Aptorum shares are urged to consult their own tax advisors concerning the application of the PFIC rules to their shares. ALL U.S. HOLDERS ARE STRONGLY URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE DOMESTICATION AND ITS APPLICATION TO THEM. 253 UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION On July 14, 2025, Aptorum Group Limited (the “Company”), entered into a Merger Agreement with DiamiR Biosciences Corp. encompassing a license agreement, management agreement and merger agreement for the purchase and sale of DiamiR Biosciences Corp.
