The proprietary technology developed at the Company is based on quantitative analysis of circulating organ-enriched microRNAs in plasma. Short-term objectives of the Company include the development of Lab-Developed tests (LDTs) under CLIA guidelines based on the identified miRNA signatures. The tests will be used for screening, patient stratification, as well as disease and treatment monitoring. The Company’s patent portfolio includes United States patents, issued between 2014 and 2024 and set to expire between 2030 and 2038, and certain foreign counterparts, in seven patent families.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">The Company was incorporated in 2014 and also operates through its wholly-owned subsidiary, DiamiR, LLC, which was incorporated as a limited liability company in Delaware in 2009.

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company performs research and development activities of its own and for others substantially in one location using resources common to internal research activities and revenue-producing services, which have been limited to date.

The Company performs research and development activities of its own and for others substantially in one location using resources common to internal research activities and revenue-producing services, which have been limited to date.

The result of this accounting treatment could be that the fair value of a financial instrument is classified as a derivative instrument and is marked-to-market at each balance sheet date and recorded as a liability. Financial instruments that are initially classified as equity that become subject to reclassification under ASC Topic 815-40 are reclassified to a liability account at the fair value of the instrument on the reclassification date. The Company has no financial instruments meeting the criteria for derivative accounting as of May 31, 2025 and 2024.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b>Stock Based Compensation</b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">The Company accounts for share-based compensation arrangements with employees and non-employees using a fair value method which requires the recognition of compensation expense for costs related to all share-based payments including share options. The fair value method requires the Company to estimate the fair value of share-based payment awards on the date of grant using an option-pricing model. The Company uses the Black-Scholes option-pricing model to estimate the fair value of options granted that are expensed on a straight-line basis over the requisite service period, which is generally the vesting period. The Company accounts for forfeitures as they occur.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b>Leases</b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">The Company accounts for its operating leases under ASC 842, <i>Leases</i>. Accordingly, the Company determines whether a contract is, or contains, a lease at inception. Right-of-use assets represent the Company’s right to use an underlying asset during the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at lease commencement based upon the estimated present value of unpaid lease payments over the lease term. The Company uses an estimated incremental borrowing rate based on the information available at lease commencement in determining the present value of unpaid lease payments.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b>Convertible Notes Payable</b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">Debt issuance costs and discounts (premiums) related to notes payable are reported as direct deductions (increases) to the outstanding debt and amortized over the term of the debt using the effective interest method as an addition (reduction) to interest expense.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">In August 2020, the FASB issued ASU No. 2020-06, <i>Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) — “Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity”</i>, which simplifies the accounting for convertible instruments by removing major separation models currently required. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. The standard also simplifies the diluted net income per share calculation in certain areas. The amendments in this update were effective for public entities that are smaller reporting companies, as defined by the Securities and Exchange Commission (“SEC”), for the fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The Company adopted the pronouncement early on a fully retrospective basis prior to the year ended May 31, 2024 and has not recognized calculated beneficial conversion features in its notes payable.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b>Segment Information</b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">FASB ASC 280, Segment Reporting (“ASC 280”), establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company performs research and development activities of its own and for others substantially in one location using resources common to internal research activities and revenue-producing services, which have been limited to date. Accordingly, the Company’s chief operating decision maker (“CODM”), the Executive Chairman, manages the Company’s business activities as a single operating and reportable segment at the consolidated level using cash flow and EBITDA measures to allocate resources and assess performance. Further, the CODM reviews and utilizes functional expenses (personnel, other research and development, and general and administrative) at the consolidated level to manage the Company’s operations. Other segment items included in consolidated net income are depreciation and amortization, stock based compensation, interest expense and the provision for income taxes.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><b>Recently Issued Accounting Pronouncements</b></p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses (“ASU 2024-03”). ASU 2024-03 requires additional disclosure of certain amounts included in the expense captions presented on the condensed consolidated statement of operations as well as disclosures about selling expenses.

The Company is currently evaluating the impact on its consolidated financial statements of the provisions of the OBBBA, which may result in a significant reduction of recorded income tax liabilities. The provisions were not effective as of May 31, 2025 and their effects, if any, are expected to be recorded in the Company’s consolidated financial statements for the year ending May 31, 2026.</p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in"> </p> <p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.25in">On July 7, 2025, DiamiR entered into a financial advisory agreement with H.C.
