During fiscal year 2023, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $368,000 at inception through June 2027. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. The present value of the minimum future obligations of $368,000 was calculated based on an interest rate of 3.5%. Depreciation and amortization expense related to this finance lease was $19,000 and $18,000 for the three months ended July 31, 2025 and 2024. Interest on the related finance lease liability was less than $1,000 and approximately $1,000 for the three months ended July 31, 2025 and 2024, respectively.

During fiscal year 2022, the Company recognized a finance lease for laboratory equipment. This equipment was obtained as the result of a laboratory supplies purchase commitment with costs of approximately $370,000 at inception through December 2025. Cash payments for this lease are in the form of consideration for purchasing lab supplies under a purchase commitment agreement. At the commencement of the commitment, the present value of the minimum future obligations of $370,000 was calculated based on an interest rate of 3.25%. Depreciation and amortization expense related to this finance lease was $19,000
and $19,000 for the three months ended July 31, 2025 and 2024, respectively. Interest on the related finance lease liability was approximately $1,300 and $2,000 for the three months ended July 31, 2025 and 2024, respectively.

As noted above, the Company's financing leases are for laboratory equipment.
