Reports Third Quarter 2025 Financial Results and Provides Strategic Initiatives Update COSCIENS voluntarily delists from Nasdaq, while retaining the Company’s listing on the TSX COSCIENS restructuring results in significantly lower cash outflow with operating expenses down 59% vs. Q3 2024. TORONTO, ONTARIO, November 11, 2025 – COSCIENS Biopharma Inc. (FINRA: CSCIF) (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 third quarter ended September 30, 2025 and provided a corporate update regarding operational and strategic developments during the quarter. “Our focus in Q3 was to ensure the zero-based budgeting and restructuring plans we designed were executed successfully to establish our go forward cost structure,” said Anna Biehn, Chief Executive Officer of COSCIENS. “Management and the Board are encouraged with the early results and have made significant progress in an assessment of the existing projects, business development efforts and future growth opportunities.” Focus on Revenue-Generating Base Business Stabilizing the core business continues to be a strong priority and management implemented measures to drive discipline in base business management, forecasting and an end-to-end procurement to manufacturing review. As a result, Q3 gross margins showed an improvement of 700 basis points over the previous quarter, driven by both cost cuts and operational improvements. Cost Structure Reset and Zero-Based Budgeting The Company launched a zero-based budgeting (ZBB) initiative in Q2 to improve the efficiency of the organizational structure. The initiative included reduction in headcount and was implemented to further align costs with strategic priorities. The cost reset and restructuring initiative began showing results in Q3 with overall operating expenses down 59% vs. Q3 2024 resulting in significantly lower cash outflow for the quarter. The business will continue to seek lower operating costs as the discipline continues.

Nasdaq Delisting – Continued Listing on TSX– Application for quotation on the OTCQB® Venture Market As previously announced, during the quarter, the Company voluntarily delisted from Nasdaq effective as of September 5, 2025, while maintaining its listing on the TSX. Following the Nasdaq delisting, FINRA’s Department of Market Operations assigned the trading symbol “CSCIF” to the Company’s common shares for quoting and trading on the informal OTC market in the United States as of September 4, 2025. On November 3, 2025 the Company applied to the OTC Markets Group Inc. for its common shares to be quoted for trading on the OTCQB® Venture Market, however, there can be no assurance that its application will be approved or the timing thereof or that any broker will make, or continue to make, a market in the Company’s common shares in the U.S. either on the informal OTC market or, if approved, on the OTCQB® Venture Market. The Company’s voluntary delisting from Nasdaq marked the first step in the Company’s broader strategy to seek 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 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. Once 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 reduce costs, with efforts designed to elevate competitiveness and maintain the Company’s viability. Portfolio Growth Assessment During the quarter, the Company undertook a strategic assessment of its key segments. Certain key results of which are summarized below: ● Active Ingredients: ○ In addition to the ongoing sales of beta glucan, avenanthramides and oat oil continue across cosmeceutical, personal care, and veterinary health markets, the Company is exploring new category expansion opportunities in food and beverage, dermatology and pharmaceutical markets. ○ As part of the same review, management evaluated the business plans for the nutraceuticals products and made the strategic decision not to enter the consumer products market given the high cost of entry, cost competitiveness, need for strong brand marketing and lack of a direct-to-consumer distribution route to market. Alternatively, the concepts are being discussed with potential customers who are interested in buying active ingredients for the business to generate revenue within the Company’s current portfolio. ● Suspension of Juvente Cosmeceuticals Line of Business ○ As part of the strategic growth review, the Company has made the decision to suspend operations and is taking steps to wind down operations for the cosmeceutical line, JuventeDC due to limited success in the direct-to-consumer e- commerce channels. ● Pharmaceuticals: ○ Macrilen – Although the Company previously announced that the Phase 3 DETECT trial evaluating Macrilen for the diagnosis of Childhood Onset Growth Hormone Deficiency (CGHD) did not achieve its predefined primary endpoints, the results still provided valuable insights to guide future development efforts. The Company began a strategic assessment of options in consultation with key opinion leaders and requested a Type C meeting with the FDA which aimed to evaluate the viability of approving the pediatric program based on the post-hoc analysis of the Phase III P02 DETECT study. Considering the known limitations in the established procedures to diagnose CGHD, the Company proposed to modify the ground truth determination, as a basis to assess the diagnostic performance of the Macrilen test. The FDA acknowledged the limitations of the current diagnostic framework which generates a high rate of false positives, but stated that redefining diagnostic thresholds is not within the FDA’s remit. The agency declined to accept the proposed alternative analysis, citing deviation from established diagnostic guidelines and concern about excluding patients from treatment eligibility. Consequently, full pediatric approval by the FDA under the current analytical proposal is unlikely at this time in the US market. The Company is evaluating its options for advancing the possible expansion of Macrilen into the US market including the possibility of submitting data for a subgroup of the pediatric population to the FDA. Additionally, the Company is evaluating seeking EMA Scientific Advice. The result of these actions could determine a possible path forward for the pediatric indication in the US and European markets. Simultaneously the Company continues to evaluate all options, including additional licensing, sale and partnership opportunities in other key markets as it pertains to the adult indication.

● Technology ○ The Company has a license for Pressurized Gas eXpanded (PGX) Technology. PGX is a patented, unique technology with several key advantages over conventional drying and purification technologies that can be used to process biopolymers into high-value and novel biocomposites. Construction of the PGX unit in Edmonton was completed in Q4 of 2024 and the PGX unit in Austria was completed in 2025 with technical validation for both units ongoing through Q3 of 2025. The Company is to reach out to potential industry partners with the capability to commercialize specialty materials such as yeast beta glucan or to leverage the technology in their own operations. Summary of Third Quarter 2025 Financial Results All amounts are in U.S. dollars. Cash and cash equivalents The Company had $8.5 million in cash and cash equivalents on September 30, 2025. Results of operations for the three-month period ended September 30, 2025 For the three-month period ended September 30, 2025, the Company reported a consolidated net loss of $1.8 million, or $0.57 in net loss per common share, as compared with a consolidated net loss of $5.8 million, or $1.85 in net loss per common share for the same period in 2024. The $4.0 million decrease in net loss is attributable to the movements described below and a recognition of impairment expense on intangible assets in the amount of $1.5 million in 2024, offset by a recognition of impairment expense on property and equipment in the amount of $0.2 million in 2025 and a write-down of inventory in the amount of $0.1 million in 2025. Revenues ● Total revenue for the three-month period ended September 30, 2025, was $1.5 million as compared to $1.9 million for the same period in 2024, a decrease of $0.4 million. This decrease was primarily due to a decrease of $0.2 million in sales of Avenanthramides, Beta Glucan and Oat Oil from prior period and $0.2 million in Macrilen due to the timing of shipments.

Operating Expenses ● Total operating expenses for the three-month period ended September 30, 2025, were $2.9 million as compared with $7.3 million for the same period in 2024.

The $0.4 million decrease in net loss is mainly attributable to the merger in 2024 and the associated professional service fees which were not repeated in 2025 as well as management’s cost cutting measures which began in 2025. Revenues ● Total revenue for the nine-month period ended September 30, 2025, was $5.7 million as compared to $6.2 million for the same period in 2024, a decrease of $0.5 million.

Operating expenses ● Total operating expenses for the nine-month period ended September 30, 2025, were $10.3 million as compared with $14.5 million for the same period in 2024.
