Financial Highlights

   Financing

• During the quarter ended October 31, 2025, the Company successfully completed $2.7 million of financing with issuance of units (common shares and warrants) through private placements, strengthening its liquidity. Cash and cash equivalents of $6.6 million at the end of the period, modestly lower than the $7.0 million reported as of July 31, 2025. The Company is debt free.

   Distribution revenues

• Distribution revenues for the three-month period ended October 31, 2025 were $1.05 million, an 83% decrease from $6.12 million in the comparable period, reflecting the expiry of the Dexlansoprazole distribution agreement in April 2025.

   Net loss

• The Company reported a net loss during the quarter of $1.6 million as compared to a net loss of $0.6 million for the same period in 2024. The comparative period increases in net loss of nearly $1 million relates to the distribution revenues decline which reduced the gross margin by $1.5 million. This reduction was partially offset by a $0.5 million savings in selling and administrative as well as financial expenses.

   Cash flows

• The Company used $2.3 million in operating activities cash flows, compared with generating $2.6 million in the same period last year. The $4.9 million decrease in operating cash flows is mainly due to the net change in non-cash working capital items for an amount of nearly $3.5 million related to the payments of accounts payable, as well as the $1.4 million higher comparative net loss net of items not affecting cash.
