Laboratory Acquisition and Intangible Assets On April 15, 2021, pursuant to an Asset Purchase Agreement, DiamiR acquired certain laboratory assets, facilities and operations from Interpace, a provider of molecular diagnostic tests. The total purchase consideration consisted of 42,820 shares DiamiR common stock with an estimated fair value of $300,000.At acquisition, $197,761 of the purchase price was allocated to laboratory certifications and licenses. At acquisition, the laboratory was in active operation, providing services to third-parties, and DiamiR accounted for the acquisition as the purchase of a business in accordance with FASB ASC Topic 805 Business Combinations. Accordingly, DiamiR recorded the assets acquired at their estimated fair values. The following table summarizes the purchase price allocation:

| Assets acquired:            |     | Estimated  
 fair value |         |
|:----------------------------|:----|:-----------|--------:|
| Property and equipment      |     | $          | 102,239 |
| Certifications and licenses |     |            | 197,761 |
| Total assets acquired       |     | $          | 300,000 |

Certifications and licenses represent the laboratory’s CLIA certification and its state operating licenses and intangible assets, which are transferable together with other related acquired assets and operations under certain conditions. DiamiR intends to use the certification and licenses to provide future proprietary and other testing services and have not identified any plans, regulatory restrictions, competition, significant maintenance costs or other factors that would limit their useful lives. Accordingly, DiamiR considers them to be indefinite-lived assets and do not amortize them. It will periodically evaluate the assets for impairment and may record charges, if and when an impairment is identified based on changes in the factors described above or on future economic or operating developments. The estimated useful lives of the property and equipment is three to seven years. 155 Income Taxes DiamiR
