TORONTO, ONTARIO, Oct. 19, 2026 (GLOBE NEWSWIRE) -- COSCIENS Biopharma Inc. (TSX: CSCI) (OTCQB: CSCIF) (“COSCIENS” or the “Company”) is pleased to announce the publication of a new corporate presentation, now available on its website at www.cosciensbio.com.

The presentation provides an overview of the Company and its operating subsidiaries, following the recent acquisition of Nualtis Corp. (“Nualtis“) and includes information relating to the ongoing private placement (the “Offering”) of 15% unsecured convertible debentures (the “Debentures”).

To date, COSCIENS has issued approximately US$12 million aggregate principal amount of Debentures and based on investor feedback and engagement, management is optimistic about the ability of the Company to raise additional funds in the coming weeks, subject to the maximum principal amount of US$20 million. Unless the maximum amount is issued sooner, the Company intends to continue marketing the Debentures through mid-November.

Funds raised to date in the Offering, along with COSCIENS’ pre-existing cash balance, are already sufficient to pay the remaining US$6 million due to AtaiBeckley in March 2027 as a deferred purchase price payment (the “Deferred Payment”) for the acquisition of Nualtis. However, COSCIENS strives to be well-capitalized with excess cash at all times. If the full US$20 million is raised in the aggregate and COSCIENS’ shareholders approve the conversion of the Debentures into common shares of COSCIENS at a shareholders’ meeting expected to be held in December, COSCIENS estimates that its pro forma market capitalization would be approximately US$27 million and the Company would have over US$7 million of cash-on-hand with no outstanding indebtedness (assuming conversion in full), after making the Deferred Payment in March.
