Properties, in its own words
We currently lease approximately 2,800 square feet of office space for our executive offices in Markham, Ontario, from 1968160 Ontario Inc., an entity affiliated with Dr. Nijhawan. Pursuant to the lease, as amended and extended on December 31, 2022, the term of the lease expired on December 31, 2024. The lease was subsequently extended to November 30, 2025 and thereafter, the arrangement continues on a month-to-month basis and either party may terminate on 30 days’ notice. We believe our current offices are sufficient to meet our needs. We may seek to negotiate new leases or evaluate additional or alternate space to accommodate operations. We believe that appropriate alternative space is readily available on commercially reasonable terms.

Risk factors and legal proceedings
The risks Edesa Biotech, Inc. names in Item 1A of its 10-K filed Dec 12, 2025: 57 risks under these headings, as written.4
- Risks Related to Our Business, Financial Position and Capital Requirements
- We are a late-stage biopharmaceutical company with no products approved for commercial sale, and we have incurred significant losses since our inception and expect to continue to incur losses and may never generate profits from operations or maintain profitability.
- Our recurring losses from operations have raised substantial doubt regarding our ability to continue as a going concern.
- We will need substantial additional funding to finance our operations through regulatory approval of one or more of our product candidates. If we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our product development programs, commercialization efforts or other operations.
- Raising additional capital may cause dilution to our investors, restrict our operations or require us to relinquish rights to our technologies or product candidates.
- Changes in the U.S. political and regulatory environment could affect availability of government funding that we or our third party collaborators may rely on, which could negatively impact the development of our product candidates.
- We partially rely on government grants to contribute to our EB05 (paridiprubart) development program. If we are unable to satisfy our contractual obligations and manage our covenants or meet expected milestones, the development of EB05 may be extended, delayed, modified, or terminated and we may be required to repay all or part of the grant earlier than expected.
- We depend heavily on the success of our drug product candidates. If we are unable to obtain regulatory approval or commercialize one or more of these experimental treatments, or experience significant delays in doing so, our business will be materially harmed. We cannot give any assurance that we will receive regulatory approval for such product candidates or any other product candidates, which is necessary before they can be commercialized.
- Deterioration in general economic conditions in the U.S., Canada and globally, including the effect of prolonged periods of inflation on our suppliers, third-party service providers and potential partners, could harm our business and results of operations.
- International trade policies, including tariffs, sanctions and trade barriers may adversely affect our current and future business, financial condition, results of operations and prospects.
- Our limited operating history may make it difficult for you to evaluate the success of our business to date and to assess our future viability.
- We are exposed to risks related to currency exchange rates.
The other 46 risks
- Our operations are subject to anti-corruption laws, including the U.S. Foreign Corrupt Practices Act (“FCPA”), and other anti- corruption laws that apply in countries where we do business and may do business in the future. We are also subject to other laws and regulations governing our international operations, including regulations administered by the government of the
- If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.
- Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading, which could cause significant liability for us and harm our reputation.
- We expect to expand our capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.
- Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.
- We rely significantly on information technology and any failure, inadequacy, interruption or security lapse of that technology, including any cybersecurity incidents, could harm our ability to operate our business effectively.
- Risks Related to Clinical Development, Regulatory Approval and Commercialization
- If clinical trials of our product candidates fail to demonstrate safety and efficacy to the satisfaction of the FDA, Health Canada (“HC”) or the European Medicines Agency (“EMA”), or do not otherwise produce favorable results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization our product candidates.
- Interim results, top-line, initial data may not accurately reflect the complete results of a particular study or trial.
- Any product candidate we advance into and through clinical trials may cause unacceptable adverse events or have other properties that may delay or prevent their regulatory approval or commercialization or limit their commercial potential.
- If clinical trials for our product candidates are prolonged or delayed, we may incur additional costs, and may not be able to commercialize our product candidates on a timely basis or at all.
- The clinical trial designs, endpoints and outcomes that will be required to obtain marketing approval for our drug candidates are uncertain. We may never receive marketing approval for our drug candidates.
- If the commercial opportunity in vitiligo, chronic ACD, ARDS, or pulmonary fibrosis is smaller than we anticipate, our future revenue from our drug candidates will be adversely affected and our business will suffer.
- While we have chosen to test our product candidates in specific clinical indications based in part on our understanding of their mechanisms of action, our understanding may be incorrect or incomplete and, therefore, our product candidates may not be effective against the diseases tested in our clinical trials.
- A successful sPLA2, anti-TLR4 or anti-CXCL10 drug has not been developed to date and we can provide no assurances that we will be successful or that there will be no adverse side effects.
- Even if one of our product candidates receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.
- If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and any of our other current or future product candidates, we may not be successful in commercializing the applicable product candidate if it receives marketing approval.
- We face substantial competition, which may result in others discovering, developing or commercializing products to treat our target indications or markets before or more successfully than we do.
- Even if we are able to commercialize one of our product candidates, the product may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare reform initiatives, which would harm our business.
- Product liability lawsuits against us could cause us to incur substantial liabilities and limit commercialization of any products that we may develop.
- We will be dependent on third parties for manufacturing, including optimization, technology transfers and scaling up of clinical scale quantities of all of our product candidates.
- The manufacturing of our monoclonal antibody candidates is complex and subject to a multitude of risks. These manufacturing risks could substantially increase our costs and limit supply of these drug candidates for clinical development, and commercialization.
- We rely on third parties to conduct our clinical trials and those third parties may not perform satisfactorily, including failing to meet deadlines for the completion of such clinical trials.
- If we are not able to establish or maintain additional partnerships or collaborations, we may have to alter our development and commercialization plans.
- Even if we complete the necessary clinical trials, the marketing approval process is expensive, time consuming and uncertain. If we are not able to obtain, or if there are delays in obtaining, required marketing approvals, we will not be able to commercialize our product candidates, and our ability to generate revenue will be materially impaired.
- Even if we obtain marketing approval for our product candidates, the terms of approvals and ongoing regulation of our products may limit how we manufacture and market our products, and compliance with such requirements may involve substantial resources, which could materially impair our ability to generate revenue.
- We may not be able to obtain or maintain orphan drug designation or exclusivity for our product candidates.
- Increasing use of social media platforms could give rise to liability, breaches of data security and privacy laws, or reputational damage.
- Risks Related to Our Intellectual Property
- We are dependent on license relationships with third parties for our key drug development programs.
- If we are unable to obtain and maintain patent protection for our licensed technology and products, or if the scope of the patent protection is not sufficiently broad, our competitors could develop and commercialize technology and products similar or identical to ours, and our ability to successfully commercialize our licensed technology and products may be adversely affected.
- We may become involved in lawsuits or other enforcement proceedings to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and potentially unsuccessful.
- Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a material adverse effect on the success of our business.
- Intellectual property litigation could cause us to spend substantial resources and could distract our personnel from their normal responsibilities.
- If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
- Risks Related to Owning Our Securities
- The price of our common shares may continue to be volatile.
- Our common shares are listed on The Nasdaq Capital Market. We must satisfy the continued listing requirements of Nasdaq, to maintain the listing of our common shares on The Nasdaq Capital Market.
- We do not currently intend to pay dividends on our common shares in the foreseeable future, and consequently, any gains from an investment in our common shares will likely depend on appreciation in the price of our common shares.
- A sale of a substantial number of our common shares in the public market could cause the market price of our common shares to drop significantly, even if our business is doing well.
- If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our common shares, the price of our common shares could decline.
- Our directors, executive officers and certain other holders of our securities have control over us and could delay or prevent a change of corporate control.
- Our Articles allow for our board of directors to create new series of preferred shares without further approval by the shareholders, which could adversely affect the rights of the holders of our common shares.
- Our common shares rank junior to our preferred shares in the event of a liquidation, dissolution or winding-up of the Company.
- Any issuance of our common shares upon conversion of our preferred shares will cause dilution to our then existing stockholders and may depress the market price of our common shares.
- We may incur future indebtedness that will rank senior to our preferred shares or issue additional series of preferred shares that rank on a parity with, or senior to, the preferred shares as to dividend payments and liquidation preference.
- Failure to maintain effective internal control over financial reporting could have a material adverse effect on our share price.
- The ownership of our common shares is highly concentrated, which may prevent you and other shareholders from influencing significant corporate decisions and may result in conflicts of interest that could cause our common shares price to decline.
- We may be deemed a passive foreign investment company, and as a result, U.S. shareholders may be subject to special taxation rules that restrict capital gains treatment, unless the shareholders make a timely tax election to treat the company as a qualified electing fund.
Legal proceedings
From time to time, we may be involved in legal proceedings, claims and litigation arising in the ordinary course of business, including contract disputes, employment matters and intellectual property disputes. We are not currently a party to any material legal proceedings or claims outside the ordinary course of business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
