**COSCIENS Biopharma Inc. Reports Fourth Quarter and Full Year 2025 Financial Results and Provides Corporate Update**

 

**TORONTO, ONTARIO, March 25, 2026** – COSCIENS Biopharma Inc. (TSX: CSCI) (OTCQB: CSCIF) ("**COSCIENS**" or the "**Company**"), a life science company focused on the development of natural, plant-based active ingredients, today reported its financial and operating results for the fourth quarter and full year ended December 31, 2025. All amounts in this press release are in U.S. dollars.

**Corporate Update**

Following the reconstitution of the Company's board of directors (the "**Board**") on May 30, 2025, the Company has undertaken a series of initiatives designed to follow through on the commitment of the reconstituted Board to actively review COSCIENS' prospects and opportunities, and to take the actions necessary to best position COSCIENS to create value for shareholders. Notably, during the second half of 2025, the Company executed a comprehensive restructuring plan designed to streamline operations and enhance efficiency. Through this restructuring, combined with disciplined cost management and targeted cost reduction initiatives, the Company has meaningfully reduced its burn rate and right sized the organization to better align with current market conditions and growth opportunities.

More recently, on March 5, 2026, the Company announced that it had made the strategic decision to cease funding its German subsidiaries, through which it has historically pursued the development of its pharmaceutical therapeutic assets, including its main pharmaceutical asset, Macrilen® (macimorelin), (collectively, the "**Biopharmaceutical Business**"). As a result of the Company's decision, on March 23, 2026, an application was filed in a German court to open insolvency proceedings in respect of the German subsidiaries. The Company anticipates these developments will generate approximately $1.9 million in annualized cost savings by eliminating ongoing operating losses at the subsidiary level and reducing administrative costs at the corporate level. It is also expected that the German subsidiaries will cease to be consolidated entities in the Company's financial statements, and that their liabilities, (including the liability for employee future benefits resulting from unfunded pension liabilities, which were $11.0 million at December 31, 2025) will cease to be reflected on the Company's future financial statements.

The Company also continues to advance its efforts to further reduce administrative costs by terminating or suspending its public reporting obligations under the Securities Exchange Act of 1934 ("**Exchange Act**") and expects to submit a related proposal to shareholders at the annual shareholder meeting to be held this June. Further information will be provided in due course, but for greater certainty, the Company intends to continue to meet its public reporting obligations as a "reporting issuer" under applicable Canadian securities laws, and for its Common Shares to remain listed on the TSX and traded on the OTC market.

"We have taken a number of critical steps over the past year to strengthen our foundation and better position the Company financially. Looking ahead to the remainder of 2026, we remain committed to pursuing additional cost-savings, to achieving profitability, and to evaluating opportunities to enhance shareholder value through both organic growth initiatives and strategic transactions," said Peter Puccetti, Interim CEO and Chairman of the Board.

**Financial Summary**

● $7.3 million in cash and cash equivalents at December 31, 2025.

● Consolidated net loss for Q4 2025 of $2.2 million, or $0.69 loss per common share, as compared with $6.7 million and $2.15, respectively, for Q4 2024. The $4.5 million decrease in net loss is primarily due to decreases in impairment expenses (of $2.8 million), in R&D costs (of $2.3 million), in income tax expense (of $1.0 million), and in SG&A expenses (of $0.3 million); which factors were partially offset by decreases in gross margin (of $1.4 million) and in other income (of $0.5 million).

● Consolidated net loss for FY 2025 of $10.4 million, or $3.27 loss per common share, as compared with $15.3 million and $5.93, respectively, for FY 2024. The $4.9 million decrease in net loss is primarily due to a decrease in impairment expense of $4.0 million, a decrease in R&D costs of $5.4 million, and a decrease in SG&A expenses of $0.4 million; offset by a decrease in other income of $2.7 million, a decrease in gross margin of $2.1 million, and a write-down of inventory of $0.1 million.

● Total revenue for Q4 2025 was $1.8 million as compared to $3.3 million for Q4 2024, a decrease of $1.5 million. This decrease was primarily due to decreases in pharmaceutical revenue (of $0.9 million, primarily as a result of $0.7 million in recognized breakage revenue in Q4 2024, following the unexpected results of the pediatric trial) and in sales of active ingredients (of $0.6 million due largely to the timing of shipments).

![](ex99-1_001.jpg)

● Total revenue for FY 2025 was $7.5 million as compared to $9.6 million for FY 2024, a decrease of $2.1 million. This decrease was primarily due to a decrease of $1.5 million in sales of active ingredients, as well as a decrease in pharmaceutical revenue (of $0.6 million, primarily as a result of $0.7 million in recognized breakage revenue in 2024, following the unexpected results of the pediatric trial).

● Total operating expenses for Q4 2025, were $3.0 million as compared with $8.4 million in Q4 2024. This decrease of $5.4 million was primarily due to decreases in impairment expenses (of $2.8 million), in R&D costs (of $2.3 million) and in SG&A expenses (of $0.3 million).

● Total operating expenses for FY 2025, were $13.3 million as compared with $23.0 million for FY 2024, a decrease of $9.7 million. This decrease was primarily due decreases in R&D costs (of $5.4 million), in impairment expenses (of $4.0 million), and in SG&A expenses (of $0.4 million); offset by a write-down of inventory of $0.1 million.
