On May 12, 2026, COSCIENS Biopharma Inc. (the "Company") issued a press release announcing its first quarter 2026 financial results. A copy of the press release is attached to this Form 6-K as Exhibit 99.1 and is incorporated by reference herein. The press release contains forward-looking statements and includes cautionary statements identifying important factors that could cause actual results to differ materially from those in the forward-looking statements.

**Forward-Looking Statements**

The information in this Report on Form 6-K and the exhibits attached hereto and incorporated herein by reference include "forward-looking statements" as well as "forward-looking information" under the provisions of Canadian securities laws. All statements, other than statements of historical fact, that address circumstances, events, activities, or developments that could or may or will occur are forward-looking statements.

Specific forward-looking information in this document includes, but is not limited to, statements relating to: the implementation of the Share Capital Amendment (as defined below), the approval of the Toronto Stock Exchange ("TSX") for the Share Capital Amendment, the timing and ability of the Corporation to complete the SEC Reporting Suspension (as defined below), the expected cost savings to the Corporation from completing the Share Capital Amendment and the SEC Reporting Suspension, the ability of the Corporation to comply with Rule 12g3-2(b) following completion of the Share Capital Amendment, the anticipated effect of the Share Capital Amendment on the price of the Corporation's Common Shares, the Corporation's ability to continue to meet its public reporting obligations as a "reporting issuer" under applicable Canadian securities laws and the Corporation's expected cost savings from the insolvency of its German subsidiaries. When used in this Report on Form 6-K and the exhibit attached hereto and incorporate herein by reference, words such as "anticipate", "assume", "believe", "could", "expect", "forecast", "future", "goal", "guidance", "intend", "likely", "may", "would" or the negative or comparable terminology as well as terms usually used in the future and the conditional are generally intended to identify forward-looking statements, although not all forward-looking statements include such words.

Forward-looking statements involve known and unknown risks and uncertainties, and other factors which may cause the actual results, performance or achievements stated herein to be materially different from any future results, performance or achievements expressed or implied by the forward-looking information. Such risks and uncertainties include those under the heading "Risk Factors" in the Company's most recent Annual Report on Form 20-F and other public disclosure filed or furnished under our profile on SEDAR+ at www.sedarplus.ca. or to the Securities and Exchange Commission ("**SEC**"), including the Rule 13e-3 Transaction Statement on Schedule 13E-3, filed by the Company with the SEC on April 4, 2026, as amended.

Many of these factors are beyond our control. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company does not undertake to update any forward-looking statements contained herein, except as required by applicable securities laws. New factors emerge from time to time, and it is not possible for the Company to predict all of these factors, or to assess in advance the impact of each such factor on the Company's business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement.

**COSCIENS Biopharma Inc. Reports Q1 2026 Results**

**TORONTO, ONTARIO, May 12, 2026** – COSCIENS Biopharma Inc. (TSX: CSCI) (OTCQB: CSCIF) ("**COSCIENS**" or the "**Company**") today reported its financial and operating results for the first quarter ended March 31, 2026. All amounts in this press release are in U.S. dollars.

**Q1 2026 Financial Highlights**

● $5.0 million in cash and cash equivalents at March 31, 2026.

● Consolidated net income of $10.8 million or $3.42 net income per common share, as compared with a consolidated net loss of $3.7 million, or $1.16 loss per common share for Q1 2025. The $14.4 million increase in net income is primarily attributable to the $10.9 million of Income from discontinued operations recognized upon the deconsolidation of the Company's German subsidiaries from the consolidated financial results (as further discussed below).

● Consolidated net loss from continuing operations of $0.2 million or $0.06 net loss per common share as compared to consolidated net loss from continuing operations of $2.7 million or $0.85 net loss per common share for Q1 2025. The $2.5 million decrease reflects a decrease in total operating expenses of $1.5 million, an increase in other income of $0.6 million, and increase in gross margin of $0.4 million.

● Total revenue of $1.9 million as compared to $1.4 million for Q1 2025, reflecting higher sales volumes during the period.

● Total operating expenses of $1.5 million as compared with $3.0 million for Q1 2025, reflecting a $1.2 million decrease in selling, general, and administrative expenses, and a $0.3 million decrease in research and development costs.

**Operational and Corporate Highlights**

*<u>German Subsidiary Insolvency and Deconsolidation</u>*

 

As previously announced, during Q1 the Company made the decision to cease funding its German subsidiaries, Aeterna Zentaris GmbH and Zentaris IVF GmbH. On March 23, 2026, the subsidiaries filed for insolvency in Germany, and on March 27, 2026, following the appointment of a preliminary insolvency administrator, the Company ceased to exercise control over the entities. Accordingly, the Company derecognized the assets and liabilities of these entities from its consolidated balance sheet which resulted in total income from discontinued operations of $10.9 million for the three months ending March 31, 2026. The results of operations and cash flows from the German subsidiaries were consolidated into the Company's financial statements up to March 27, 2026, and thereafter classified as discontinued operations.

![](ex99-1_001.jpg)

*<u>Plan to Suspend SEC Reporting Obligations</u>*

 

As previously announced, on April 20, 2026, the Company filed a Schedule 13E-3 with the U.S. Securities and Exchange Commission in connection with a proposed share reorganization (involving a share consolidation and subsequent share split) that could, if approved by regulators and Company shareholders, enable the Company to suspend its public reporting obligations under the Exchange Act. The Company has now set June 17, 2026 as the date for its annual general and special meeting, at which, among other things, Company shareholders will be asked to consider, and if appropriate, approve the transaction. The Company expects to mail shareholders a management proxy circular later this month and a copy of the circular, along with related documentation, will be available on the Company's profile on SEDAR+ at www.sedarplus.com and on EDGAR at <u>www.sec.gov/edgar</u>.

*<u>AvenActive Program Update</u>*

 

The Phase 2a study evaluating avenanthramides, for potential applications in managing conditions related to inflammation ("**AvenActive**"), concluded in Q3 2025, and the complete study results were received in late March 2026. While exploratory analyses showed some biomarker changes at higher doses, results were not statistically significant and are considered hypothesis generating only. Based on the data and development costs, the Company has decided not to advance the AvenActive program at this time.

"We have taken deliberate steps to improve our cost structure and sharpen our focus. The decision to cease funding the German subsidiaries and the plan to suspend SEC reporting obligations bring material cost savings benefits, thus putting the Company in a stronger position. We look forward to turning our attention to growth opportunities going forward." said Peter Puccetti Interim CEO and Chairman of the Board.
