 connection with:

| ● | the accompanying notes to the unaudited pro forma consolidated combined financial statements; |

| ● | the sections entitled “Aptorum Management’s Discussion and Analysis of Financial Condition and Results of Operations of Aptorum,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations of DiamiR,” and other financial information relating to Aptorum and DiamiR. |

The unaudited pro forma condensed
combined financial information has been prepared in accordance with Article 11 of Regulation S- X as amended by the final rule, Release
No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” Release No. 33-10786 replaces the
existing pro forma adjustment criteria with simplified requirements to depict the accounting for the transaction (“Transaction Accounting
Adjustments”) and present the reasonably estimable synergies and other transaction effects that have occurred or are reasonably
expected to occur (“Management’s Adjustments”). These pro forma adjustments were presented in separate columns after
the presentation of the combined historical information of the Company and its subsidiaries and the Target Company and its subsidiaries.
The Company has elected not to present Management’s Adjustments and will only be presenting Transaction Accounting Adjustments in
the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined financial information does
not reflect future events that may occur after the Acquisition. The unaudited pro forma condensed combined financial information is provided
for informational purposes only and is not necessarily indicative of a true picture of the financial position and the results of operations
of the combined companies following the completion of the Acquisition. The pro forma adjustments are subject to material change and are
based upon currently available information and certain assumptions that the Company believes are reasonable.

There were no significant accounting
policy differences or other items which required adjustment in the accompanying unaudited pro forma condensed combined financial statements.
