COSCIENS Biopharma (CSCIF) Risk Analysis

Our Common Shares are currently listed on both the NASDAQ and the TSX under the symbol "AEZS". We must meet continuing listing requirements to maintain the listing of our Common Shares on the NASDAQ and the TSX. For continued listing, the NASDAQ requires, among other things, that listed securities maintain a minimum closing bid price of not less than $1.00 per share, as set forth in Nasdaq Listing Rule 5450(a)(1) (the "Bid Price Rule"). Although we are in compliance with the Bid Price Rule as of the date of this Annual Report, we have previously fallen out of compliance and there is no guarantee that we will be able to maintain it going forward. If we were to fall out of compliance with the Bid Price Rule or Nasdaq's other continued listing requirements, we would consider all options to remain in compliance with the Nasdaq's continued listing requirements, including a consolidation of our Common Shares.

We have a history of operating losses. Our revenues and expenses have fluctuated in the past and may continue to do so in the future. These fluctuations could cause our share price of Common Shares or the value of our other securities to decline. Some of the factors that could cause our revenues and expenses to fluctuate include, but are not limited to, the following: - the timing and willingness of any current or future collaborators to invest the resources necessary to commercialize Macrilen™ (macimorelin);         - not obtaining necessary regulatory approvals from the United States Food & Drug Administration ("FDA"), the European Medicines Agency ("EMA"), the European Commission ("EC") or other agencies that may delay or prevent us from obtaining approval of a pediatric indication for Macrilen™ (macimorelin), which may affect the share price of our Common Shares;         - the timing of regulatory submissions and approvals;         - the nature and timing of licensing fee revenues;         - the outcome of future litigation;         - foreign currency fluctuations;         - the effects of COVID-19, including the effects of intensified efforts to contain the spread of the virus, which included, among other things, quarantines and travel restrictions;         - the timing of the achievement and the receipt of milestone payments from current or future licensing partners; and         - failure to enter into new or the expiration or termination of current agreements with suppliers who manufacture Macrilen™ (macimorelin). Due to fluctuations in our revenues and expenses, we believe that period-to-period comparisons of our results of operations are not necessarily indicative of our future performance. It is possible that in some future periods, our revenues and expenses will be above or below the expectations of securities analysts or investors. In this case, the share price of our Common Shares and the value of our other securities could fluctuate significantly or decline.

Aeterna Zentaris is a holding company and a substantial portion of our non-cash assets is the share capital of our subsidiaries. AEZS Germany, our principal operating subsidiary, based in Frankfurt, Germany, holds most of our intellectual property rights. Because Aeterna Zentaris is a holding company, our obligations to our creditors are structurally subordinated to all existing and future liabilities of our subsidiaries, which may incur additional or other liabilities and/or obligations. As a result, our rights and the rights of our creditors to participate in any distribution of the assets of any subsidiary in the event that such subsidiary were to be liquidated or reorganized or in the event of any bankruptcy or insolvency proceeding relating to or involving such subsidiary, and, therefore, the rights of the holders of our securities to participate in those assets, are subject to the prior claims of such subsidiary's creditors. To the extent that we may be a creditor with recognized claims against any such subsidiary, our claims would still be subject to the prior claims of our subsidiary's creditors to the extent that they are secured or senior to those held by us. Holders of our securities are not creditors of our subsidiaries. Claims to the assets of our subsidiaries will derive from our own ownership interest in those operating subsidiaries. Claims of our subsidiaries' creditors will generally have priority as to the assets of such subsidiaries over our own ownership interest claims and, therefore, will have priority over the holders of our securities. Our subsidiaries' creditors may from time to time include general creditors, trade creditors, employees, secured creditors, taxing authorities and creditors holding guarantees. Accordingly, in the event of any foreclosure, dissolution, winding-up, liquidation or reorganization, or a bankruptcy, insolvency or creditor protection proceeding relating to us or our property, or any subsidiary, there can be no assurance as to the value, if any, that would be available to holders of our securities. In addition, any distributions to us by our subsidiaries could be subject to monetary transfer restrictions in the jurisdictions in which our subsidiaries operate. German law, which governs our principal operating subsidiary AEZS Germany, imposes an obligation on the managing director(s) of AEZS Germany to institute insolvency proceedings of that subsidiary if the managing director(s) concludes that AEZS Germany is insolvent because it is either illiquid or "over-indebted" in accordance with the provisions of German law.

We are a company existing under the laws of Canada. A number of our directors and officers are residents of Canada or otherwise reside outside the U.S., and all or a substantial portion of their assets, and a substantial portion of our assets, are located outside the U.S. Consequently, although we have appointed an agent for service of process in the U.S., it may be difficult for investors in the U.S. to bring an action against such directors or officers or to enforce against those persons or us a judgment obtained in a U.S. court predicated upon the civil liability provisions of federal securities laws or other laws of the U.S. Investors should not assume that foreign courts (i) would enforce judgments of U.S. courts obtained in actions against us or such directors, officers or experts predicated upon the civil liability provisions of the U.S. federal securities laws or the securities or "blue sky" laws of any state within the U.S. or (ii) would enforce, in original actions, liabilities against us or such directors, officers or experts predicated upon the U.S. federal securities laws or any such state securities or "blue sky" laws.

As a public company, we are required to comply with Section 404 of the U.S. Sarbanes-Oxley Act of 2002 ("Section 404") and National Instrument 52-109 - Certification of Disclosure in Issuers' Annual and Interim Filings of the Canadian securities administrators. In any given year, we cannot be certain as to the time of completion of our internal control evaluation, testing and remediation actions or of their impact on our operations. Upon completion of this process, we may identify control deficiencies of varying degrees of severity under applicable SEC and Public Company Accounting Oversight Board (U.S.) rules and regulations. As a public company, we are required to report, among other things, control deficiencies that constitute material weaknesses or changes in internal controls that, or that are reasonably likely to, materially affect internal controls over financial reporting. A "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. If we fail to comply with the requirements of Section 404 or similar Canadian requirements, or if we report a material weakness, we might be subject to regulatory sanction and investors may lose confidence in our consolidated financial statements, which may be inaccurate if we fail to remedy such material weakness.

Any additional or future issuance of securities or convertible securities, including the issuance of securities upon the exercise of stock options and upon the exercise of warrants or other convertible securities or securities pursuant to which Common Shares are issuable, could dilute the interests of our existing shareholders, and could substantially decrease the trading share price of our Common Shares. We may issue equity securities in the future for a number of reasons, including to finance our operations and business strategy, to satisfy our obligations upon the exercise of options or warrants, or for other reasons. Our stock option plans generally permit us to have outstanding, at any given time, stock options that are exercisable for a maximum number of Common Shares equal to 11.4% of all then issued and outstanding Common Shares. In addition, the share price of our Common Shares could also be affected by possible sales of securities by investors who view other investment vehicles as more attractive means of equity participation in us and by hedging or arbitrage trading activity that may develop involving our securities. This hedging or arbitrage could, in turn, affect the trading share price of our Common Shares.

In order to maintain our current status as a foreign private issuer, either (1) a majority of our Common Shares must not be either directly or indirectly owned of record by residents of the U.S. or (2) (a) a majority of our executive officers and of our directors must not be U.S. citizens or residents, (b) more than 50 percent of our assets cannot be located in the U.S. and (c) our business must be administered principally outside the U.S. In 2023, our management conducted its annual assessment of the various facts and circumstances underlying the determination of our status as a foreign private issuer and based on the foregoing, our management has determined that, as of the date of such determination and as of June 30, 2023, we continued to be a foreign private issuer. There can be no assurance, however, that we will remain a foreign private issuer either in 2024 or in future financial years. If we were to lose our foreign private issuer status as of June 30 of any given financial year, we would be required to comply with the Securities Exchange Act of 1934 reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC rules and the NASDAQ listing standards. The regulatory and compliance costs to us of complying with the reporting requirements applicable to a U.S. domestic issuer under U.S. securities laws may be higher than the cost we have historically incurred as a foreign private issuer. As a result, we would expect that a potential loss of foreign private issuer status at some future point in time could increase our legal, financial reporting and accounting compliance costs, and it is difficult at this time to estimate by how much our legal, financial reporting and accounting compliance costs may increase in such eventuality.

Our articles of incorporation, as amended, authorize the issuance of an unlimited number of "blank check" preferred shares, which could be issued by our Board without shareholder approval and which may contain liquidation, dividend and other rights equivalent or superior to our Common Shares. In addition, we have implemented in our constating documents an advance notice procedure for shareholder approvals to be brought before an annual meeting of our shareholders, including proposed nominations of persons for election to our Board. These provisions, among others, whether alone or together, could delay or impede hostile takeovers and changes in control or changes in our management. Any provision of our constating documents that has the effect of delaying or deterring a change in control could limit the opportunity for our shareholders to receive a premium for their Common Shares and could also affect the price that some investors are willing to pay for our Common Shares.

Proxy contests have been waged against many companies in the biopharmaceutical industry over the last few years. If faced with a proxy contest, we may not be able to successfully respond to the contest, which would be disruptive to our business. Even if we are successful, our business could be adversely affected by a proxy contest because: - responding to proxy contests and other actions by activist shareholders may be costly and time-consuming, and may disrupt our operations and divert the attention of management and our employees; - perceived uncertainties as to the potential outcome of any proxy contest may result in our inability to consummate potential acquisitions, collaborations or in-licensing opportunities and may make it more difficult to attract and retain qualified personnel and business partners; and - if individuals that have a specific agenda different from that of our management, or other members of our board of directors are elected to our Board as a result of any proxy contest, such an election may adversely affect our ability to effectively and timely implement our strategic plan and to create value for our shareholders.
