Operating Activities

Net cash used in operating
activities for the year ended May 31, 2025 were comparable to the prior period as lower revenue was offset by lower costs. An increase
in the Company’s net loss was offset by the collection of unbilled revenue and deferred revenue. The Company’s accounts payable
and accrued expense balances increased in each year.

Financing Activities

Net cash provided by financing
activities was $300,000 for the year ended May 31, 2025, representing proceeds from a founder loan. Proceeds from founder loans amounted
to $200,000 in the year ended May 31, 2024.

Funding Requirements

DiamiR has not completed development
of any of its product candidates. DiamiR expects to continue to incur operating losses in the foreseeable future. Subject to receiving
additional financing, it anticipates that its expenses will increase substantially due to continued development of CogniMIR,
increased development activities for pipeline projects and planned commercialization efforts.

DiamiR expects that its existing
cash and cash equivalents, and anticipated interest income, will not enable it to complete its development of CogniMIR.
