COSCIENSBiopharma Inc. Reports Second Quarter 2025 Financial Results and Provides Strategic Initiatives Update
COSCIENS Board of Directors approves a plan to voluntarily delist from Nasdaq, while retaining the Company’s listing on the TSX
TORONTO,ONTARIO, August 14, 2025 – COSCIENS Biopharma Inc. (NASDAQ: CSCI) (TSX: CSCI) (“COSCIENS” or the “Company”), a life science company focused on natural ingredients and pharmaceutical solutions, today reported its financial and operating results for the second quarter ended June 30, 2025 and provided a corporate update following significant operational and strategic developments during the quarter.
Q2 2025 Highlights
| ● | Revenue increased by 17% compared to Q2 2024 |
|---|---|
| ● | Q2 Gross profit increased by 19% compared to Q2 2024 |
| ● | Operating expenses reduced by 28% compared to Q2 2024 |
| ● | Completed a strategic reconstitution of the Board of Directors and onboarded new CEO |
| ● | Initiated a corporate restructuring during and continuing after Q2 2025 that resulted in a 27% workforce reduction to support leaner operations |
| ● | Progress made across three<br> strategic pillars: base business optimization, cost structure realignment, and portfolio growth evaluation |
Board of Directors and Management Commentary
“The newly reconstituted Board of Directors is working closely with management of COSCIENS to identify and execute upon operational and strategic priorities.” said Peter Puccetti, Chairman of the Board of Directors of COSCIENS. “While early in the tenure of this Board, we are encouraged by the significant steps recently taken.”
“Q2 2025 marks a foundational realignment of the Company’s strategic focus and cost structure,” said Anna Biehn, Chief Executive Officer of COSCIENS. “Management and the Board have worked quickly to reshape the business to focus on operational discipline, cost control and product portfolio optimization intended to position us for long-term sustainable growth.”

Strategic and Operational Updates
Leadershipand Board Reconstitution
During Q2 2025, the Company welcomed a new CEO and reconstituted its Board of Directors. The six-member Board, consisting of directors: Anthony J. Giovinazzo, Ulrich Kosciessa, Ronald W. Miller, Peter H. Puccetti, Robert A. Seager and David Spear (the “Reconstituted Board”), has provided strategic oversight and guided a comprehensive review of COSCIENS’ operational and financial priorities.
Focuson Revenue-Generating Base Business
During the quarter, management undertook a detailed operational review to identify areas for improvement across commercial execution, supply chain operations, and margin structure. Initiatives were implemented to increase discipline in the management of the base business, improve sales forecasting, and explore new business development opportunities within the Company’s existing portfolio of active ingredients.
CostStructure Reset and Zero-Based Budgeting
The Company launched a zero-based budgeting (ZBB) initiative to improve the efficiency of the organizational structure. The restructuring plan included a 27% reduction in headcount and was implemented shortly after quarter-end to further align costs with strategic priorities. Operating expenses declined by 27% compared to Q2 2024 and full run-rate savings are expected to materialize in early 2026.
NasdaqDelisting – Continued Listing on TSX
The Company’s common shares are currently traded on both the TSX and the Nasdaq Capital Market. The external audit, legal and listing costs incurred to maintain dual listing have continued to grow and require significant internal resources. In the last year, the opportunities for biotech companies to conclude financings on Nasdaq have deteriorated further thereby reducing cost benefit ratio to the Company of being listed on two exchanges. Therefore, as part of the cost savings agenda and to provide the Company with the opportunity to focus its resources on its core business needs to remain competitive in the biotechnology and pharmaceutical industry, the Board has approved, and today, the Company notified Nasdaq of its decision to voluntarily delist from the Nasdaq Stock Market. The Company will continueto maintain its listing on the Toronto Stock Exchange (TSX).
The Company intends to file a Form 25 with the U.S. Securities and Exchange Commission (the “SEC”) on or about August 25, 2025, and provide a copy thereof to the Nasdaq to effect the delisting. The delisting is expected to be effective on or about September 5, 2025, ten (10) days after the filing of the Form 25. If the delisting is effective on September 5, 2025, the Company anticipates that the last day of trading of its ordinary shares on Nasdaq will be on or about September 4, 2025.

Following the Nasdaq delisting, COSCIENS expects that its common shares will begin trading in the over-the-counter (OTC) marketplace in the U.S., however, there can be no assurance that any broker will make, or continue to make, a market in the Company’s ordinary shares in the U.S., and continue trading in Canada on the TSX. Delisting from Nasdaq marks the first step in the Company’s broader strategy to cease its public reporting obligations in the U.S. Accordingly, the Company intends to file a Form 15-F with the SEC in the future once it is able to do so pursuant to the SEC’s rules to deregister from, and terminate its reporting obligations under, the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), including its obligations to file and submit annual reports on Form 20-F and reports on Form 6-K in the U.S. with the SEC. If the Company files a Form 15-F with the SEC, its U.S. reporting obligations with the SEC will be immediately suspended at that time, and deregistration from the Exchange Act would be effective 90 days after the filing of the Form 15-F, at which time the Company’s U.S. reporting obligations thereunder would be fully terminated.
As a life science company, it is important for the Company to continue to focus on both short term and future growth. Given the current economic environment and ecosystem, the Company believes this strategic decision will position COSCIENS to enhance efficiency and reduced costs, with efforts designed to elevate competitiveness and maintain the Company’s viability.
PortfolioGrowth Assessment
The Company completed a strategic assessment of its key product segments:
| ● | Active Ingredients: |
|---|---|
| ○ | Ongoing sales of beta glucan and<br> avenanthramides continue across cosmeceutical, personal care, and veterinary health markets. The Company is exploring new category<br> expansion opportunities. |
| --- | --- |
| ○ | COSCIENS has developed beta glucan-based bars and immune-boosting<br> yeast beta glucan capsules using its proprietary processing technology, PGX, and active ingredients. The Company is exploring how<br> these products could be commercialized, given the Company does not currently have a direct-to-consumer platform. |
| ● | Pharmaceuticals: |
| --- | --- |
| ○ | Macrilen<br> – Although the Company previously announced that the Phase 3 DETECT trial evaluating Macrilen for the diagnosis of Childhood<br> Onset Growth Hormone Deficiency (CGHD) did not achieve its predefined primary endpoints, the results still provided valuable insights<br> to guide future development efforts. The Company began a strategic assessment of options, including a post hoc analysis in consultation<br> with key opinion leaders and have confirmed a Type C meeting with the FDA expected in the second half of the year to determine the<br> feasibility of a possible path forward for that pediatric indication. Simultaneously the Company continues to evaluate all options,<br> including additional licensing, sale and partnership opportunities. |
| --- | --- |
| ○ | The Company’s inflammation-related program (“AvenActive”)<br> completed its Phase 1 study without significant safety concerns. A 20-patient Phase 2a study is now underway and expected to conclude<br> in Q3 2025. The Company will determine the next phase based on efficacy insights and regulatory discussions. |

Revenues
| ● | Total<br> revenue for the three-month period ended June 30, 2025, was $2.7 million as compared to $2.3 million for the same period in 2024,<br> an increase of $0.4 million. This increase was primarily due to a $0.1 million increase in sales of Avenanthramides, Beta Glucan,<br> and Oat Oil from prior period and the inclusion of $0.3 million Macrilen revenue in the combined results due to the timing of the<br> merger completed in June 2024. |
|---|
OperatingExpenses
| ● | Total<br> operating expenses for the three-month period ended June 30, 2025, were $3.3 million as compared with $4.6 million for the same period<br> in 2024. This decrease of $1.3 million was due primarily to the merger completed in June 2024, as well as a decrease in research<br> and development costs of $0.8 million related to activities associated with the AVA trial. |

The $3.2 million increase in net loss is mainly attributable to the timing of the merger in 2024 and a decrease of the change in fair value of warrant and DSU liabilities.
Revenues
| ● | Total<br> revenue for the six-month period ended June 30, 2025, was $4.2 million as compared to $4.4 million for the same period in 2024, a<br> decrease of $0.2 million. This decrease was primarily due to a decrease of $0.6 million in sales of Avenanthramides, Beta Glucan<br> and Oat Oil from prior period, offset in part by the inclusion of a $0.4 million increase in Macrilen revenue in the combined results<br> due to the timing of the merger in 2024. |
