[SUPPL] EUPRAXIA PHARMACEUTICALS INC. SEC Filing

Rhea-AI Filing Summary

Eupraxia Pharmaceuticals is offering common shares and other securities under a shelf prospectus for aggregate proceeds up to US$200.0 million. The supplement describes an at-the-market/underwritten offering with per-share pricing shown at US$5.50 and related totals (e.g., US$70,000,001.50 and US$65,100,001.39 depending on options). Proceeds are allocated to clinical development, scale-up and corporate purposes, with explicit estimated line items including US$28.4 million, US$5.0 million, US$7.1 million and US$3.4 million. The company is developing EP-104 family products: EP-104IAR (knee OA) and EP-104GI (EoE), with ongoing Phase 1b/2a and Phase 2/Phase 3 planning and FDA interactions described. The prospectus details securities, dilution mechanics, tax and PFIC considerations for U.S. holders, risks including regulatory, clinical trial, funding and commercialization uncertainties, and potential reliance on partners and CROs.

Positive

• Shelf capacity of up to US$200.0 million provides significant financing flexibility.
• Explicit estimated use of proceeds includes US$28.4 million for scale-up/development and other line items, showing allocation priorities.
• Regulatory engagement noted: FDA pre-IND feedback and agreement on late-phase requirements for EP-104IAR.

Negative

• Offering will cause dilution; mechanisms (warrants, convertible securities, Class B exchanges) could further increase share count.
• Development of EP-104IAR and EP-104GI requires substantial additional funding and successful late-stage trials; failure or delays would harm business.
• Material risks disclosed: reliance on CROs, regulatory approvals, reimbursement uncertainty, and potential loss of foreign private issuer status impacting compliance costs.

Insights

Biotech Financial Analyst

TL;DR: Shelf offering up to US$200M funds development but raises dilution and execution risks around EP-104 programs.

The filing shows a material financing capacity via a US$200 million shelf and a specific common share tranche priced at US$5.50 that would raise tens of millions if fully exercised. Management intends to use proceeds for clinical development, manufacturing scale-up and general corporate purposes, with explicit allocations that give near-term runway for key activities. Key investor implications include near-term dilution, dependence on further financings or partnerships for Phase 3 and commercialization, and standard biotech execution risks (regulatory, CRO reliance, enrollment). The tax and PFIC disclosures increase complexity for U.S. holders and may affect after-tax returns.

Regulatory / Clinical Development Specialist

TL;DR: EP-104 programs have completed early interactions with regulators but require significant late-stage work and resources.

The supplement documents ongoing Phase 1b/2a (EP-104GI) and Phase 2 data and Phase 3 planning (EP-104IAR), plus FDA feedback on late-phase requirements. This indicates regulatory engagement but highlights that pivotal trials, manufacturing and non-clinical packages remain necessary for NDA submissions. Material operational needs include CRO performance, cGMP/GCP compliance, patient enrollment risks, and potential post-approval obligations. These are typical but material for timing and cost of potential approvals.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights selected information contained elsewhere in this prospectus supplement. This summary does not contain all the information that you should consider before deciding to invest in our common shares. You should read the entire prospectus supplement and the shelf prospectus, including the documents incorporated by reference herein, carefully, including “Risk Factors” in this prospectus supplement and the shelf prospectus and our financial statements and notes to those financial statements, before making an investment decision.

Overview

We are a clinical-stage biotechnology company seeking to leverage our proprietary DiffuSphere^™ technology to optimize drug delivery for applications with significant unmet medical need. Each of our product candidates is designed to improve patient benefit by providing more prolonged activity than currently available treatments, combined with an improved pharmacokinetics (“PK”) and related safety profile and precisely targeted local delivery. We believe a product with this profile could offer the dual potential of providing long-lasting treatment while minimizing tolerability complications in target and non-target tissues. Our strategy is to develop a portfolio of product candidates based on this delivery technology.

We currently have two distinct clinical development programs, one targeting eosinophilic esophagitis (“EoE”) and the second targeting chronic osteoarthritis (“OA”) pain in the knee. Both programs are broadly based upon the same active pharmaceutical ingredient (“API”), fluticasone propionate. The injectable drug is dispensed together with a “vehicle” diluent specifically designed for the target delivery modality and co-administered with the API. For our ongoing clinical studies, we are using the same underlying API and extended-release formulation. In the future, we anticipate that therapeutic targets will be differentiated by dosing levels, vehicle and delivery methods and will be distinct product candidates. The product candidate that is being developed specifically for submucosal injections in the gastrointestinal (“GI”) tract with an initial indication of EoE is referred to as EP-104GI, and the product candidate that is being developed for intra-articular (“IA”) injections with an initial indication of knee OA is referred to as EP-104IAR. EP-104 is intended to refer to the extended-release fluticasone propionate encapsulated with the DiffuSphere^™ technology, which is used in the formulation of both EP-104GI and EP-104IAR.

We are currently conducting a Phase 2 clinical trial (“RESOLVE”) with EP-104GI in Canada, the Netherlands, Australia, New Zealand, the United Kingdom and Switzerland. We also received pre-Investigational New Drug (“IND”) feedback from the U.S. Food and Drug Administration (“FDA”) on December 3, 2024, to clarify early phase program requirements for conducting studies in the United States. We intend to continue development of EP-104GI through the ongoing clinical trial and any subsequent trials and other testing required by the FDA for submission of a New Drug Application (“NDA”) to obtain marketing authorization from the applicable regulatory authorities in the jurisdictions where we plan to commercialize the product. We intend to evaluate the possibility of identifying a corporate partner to help with the development of EP-104GI outside of the United States.

We have successfully completed a Phase 2b clinical trial with EP-104IAR in knee OA, and in January 2024, we held a meeting with the FDA to determine the late-phase program requirements for an NDA submission and potential approval in the United States. We reached an agreement with the FDA on the clinical and non-clinical programs required to achieve marketing authorization. We believe that the future success of the product candidate will be dependent on late phase development and commercialization expertise and will require significant resources. We are currently evaluating funding alternatives for the continued development of EP-104IAR, including potential partnership opportunities and intend to modulate investment levels pending the outcomes. We are undertaking certain preclinical and manufacturing activities as well as Phase 3 planning and preparation related to EP-104IAR to ensure continuity of the project, but we intend to wait until we have funding needs addressed before committing to additional significant spend for this program.

Table of Contents

Throughout 2025, the Company announced interim data from the RESOLVE Phase 1b/2a clinical trial evaluating the safety and efficacy of EP-104GI for the treatment of EoE. The data to date from all cohorts suggest that EP-104GI continues to be released into the esophagus at a relatively constant rate from week 2 through month 12.

In September 2025, the Company announced additional clinical data from the ongoing RESOLVE Phase 1b/2a trial, including the first results for 12 months follow-up after treatment with EP-104GI. These results showed that two of three patients in Cohort 5 (48 mg total dose; 4 mg per site) remained in clinical remission for one year. The Company observed that all dose cohorts evaluated through nine months (cohorts 5 and 6) maintained what the Company believes to be clinically meaningful improvements in tissue health, similar to that observed at 3 months as measured by the EoE Histological Scoring System (“EoEHSS”).

The Company has also observed a general trend in which patients receiving higher doses of EP-104GI and exhibiting higher plasma levels appear to show greater histologic and symptomatic improvements. This trend was also observed in the four-week data (cohorts 8 and 9) from patients receiving the 120 mg or 160 mg total dose (administered across 20 injection sites).

To date, no serious adverse events (“SAEs”), nor any reported cases of oral or gastrointestinal candidiasis, have been observed in the trial.

The Company began enrollment in the Phase 2b placebo-controlled portion of the EP-104GI RESOLVE trial in July 2025.

Forward-looking information involves known and unknown risks and uncertainties, many of which are beyond our control, that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. These risks and uncertainties include, but are not limited to, those described in greater detail under “Risks Factors” in this prospectus supplement, the shelf prospectus and the documents incorporated by reference herein and therein, including:

• we have a history of negative operating cash flow and may continue to experience negative operating cash flow;

• we have a limited operating history and have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability;

• we are substantially dependent on the success of our lead product candidates EP-104GI, which is currently being studied in an open label Phase 2 clinical study, and EP-104IAR, for which we are evaluating funding alternatives for the continued development, including potential partnership opportunities.

• our lead product candidates may not be successful for their intended use;

If any of our third-party manufacturers encounter such difficulties, our ability to provide adequate supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or prevented;

MARKETING MATERIALS

Before filing the prospectus supplement in respect of this offering, we and the underwriters held road shows from September 16, 2025 to September 22, 2025, to which potential investors in the United States and in each of the provinces of Canada, except Quebec, were able to attend. We and the underwriters provided marketing materials to those potential investors in connection with those meetings, relying on an exemption under applicable Canadian securities legislation that allows issuers in certain U.S. cross-border offerings not to file marketing materials relating to those road show meetings on the SEDAR+ website (www.sedarplus.ca) or include or incorporate them by reference in the final prospectus supplement.

In order to rely on this exemption, we and the underwriters are required to give Canadian investors certain contractual rights in the event that the marketing materials described above contain a misrepresentation. Accordingly, we and the underwriters have agreed that, in the event that the marketing materials contain a misrepresentation (as defined in applicable Canadian securities laws), a purchaser resident in each of the provinces of Canada, except Quebec, who was provided with those marketing materials in connection with the road shows and who purchased the securities offered under this prospectus supplement during the period of distribution shall have, with respect to the misrepresentation and without regard to whether the purchaser relied on it, equivalent rights against us and the underwriters as the rights provided under the securities laws of the jurisdiction of Canada in which that purchaser resides, subject to the defenses, limitations and other terms of such securities laws, as if the misrepresentation was contained in this prospectus supplement.

However, this contractual right does not apply (i) to the extent that the contents of the marketing materials relating to the road shows have been modified or superseded by a statement in this prospectus supplement, and (ii) to any “comparables” as such term is defined in National Instrument 41-101 – General Prospectus Requirements in the marketing materials provided in accordance with applicable securities legislation.

Additional risks and uncertainties of which we currently are unaware or that are unknown or that we currently deem to be immaterial could have a material adverse effect on our current and projected business operations and our financial condition and results of operations. Our Risk Factors are not guarantees that no such conditions exist as of the date of this prospectus supplement and should not be interpreted as an affirmative statement that such risks or conditions have not materialized, in whole or in part. We cannot assure you that we will successfully address any or all of these risks. For additional information in respect of the risks affecting our business, see the section “Risk Factors” of our Annual Information Form, which is incorporated herein by reference and is available under our profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov/edgar.

As a result, an investor will be relying on the judgment of management for the application of the proceeds. Our management may use the net proceeds other than as described under the heading “Use of Proceeds” if they believe it would be in our best interest to do so and in ways that an investor may not consider desirable. The results and the effectiveness of the application of the proceeds are uncertain. If the proceeds are not applied effectively, our results of operations may suffer.

New investors in our common shares will experience immediate and substantial dilution after this offering.

Since the public offering price for our common shares in this offering is substantially higher than the net tangible book value per common share outstanding prior to this offering, you will suffer immediate and substantial dilution in the net tangible book value of the common shares you purchase in this offering. If the underwriters exercise their option to purchase additional common shares, you will experience additional dilution.

The issuance of additional common shares could be dilutive to shareholders if they do not invest in future offerings. In addition, we have a significant number of outstanding stock options, outstanding warrants that are exercisable for common shares, and Series 1 Preferred Shares that are convertible into common shares to purchase our common shares. If these securities are exercised or converted, as applicable, you may incur further dilution. Moreover, to the extent that we issue additional options to purchase, or securities convertible into or exchangeable for, common shares in the future and those options or other securities are exercised, converted or exchanged, shareholders may experience further dilution.

Investors may lose their entire investment.

An investment in the common shares is speculative and may result in the loss of an investor’s entire investment in us. Only investors who are experienced in high-risk investments and who can afford to lose their entire investment should consider an investment in us.

We have no history of dividends.

To date, we have not paid any dividends on the outstanding common shares. We currently intend to retain future earnings to finance the operation, development and expansion of our business. We do not anticipate paying cash dividends on the common shares in the foreseeable future. Any decision to pay dividends on our shares will be made at the discretion of our board of directors and will depend on our earnings, financial requirements and other conditions existing at such time, including potential restrictions on paying dividends pursuant to any effective credit agreements.

Our existing executive officers and directors own a significant percentage of common shares and may have a significant impact over matters submitted to our shareholders for approval.

Our executive officers and directors own approximately 14.16% of the issued common shares as of June 30, 2025. As a result, these shareholders, if they acted together, could significantly impact all matters requiring approval by our shareholders, including the election of directors and the approval of mergers or other business combination transactions. The interests of these shareholders may not always coincide with our interests or the interests of other shareholders. This may also prevent or discourage unsolicited acquisition proposals or offers for the common shares that other shareholders may feel are in their best interest.

Future sales of common shares by our existing shareholders could cause our share price to decline.

Subject to compliance with applicable securities laws, our officers, directors and significant shareholders may sell some or all of their common shares in the future. No prediction can be made as to the effect, if any, such future sales of common shares will have on the market price of the common shares prevailing from time to time. However, the future sale of a substantial number of common shares by our officers, directors and significant shareholders or the perception that such sales could occur, could adversely affect prevailing market prices for the common shares.

We will need to raise additional financing in the future which may dilute our share capital.

Our notice of articles and articles (the “Articles”) permit the issuance of an unlimited number of common shares. Future issuances of common shares will result in dilution to the existing shareholders. Additionally, future sales of the common shares into the public market may lower the market price that may result in losses to our shareholders. We may, from time to time, issue stock options to purchase additional common shares in accordance with the policies of the TSX and Nasdaq. Most of these common shares, including the common shares to be issued upon exercise of options, are freely tradable or will be freely tradeable after a four-month restriction period. Sales of substantial amounts of the common shares into the public market, or even the perception by the market that such sales may occur, may lower the market price of common shares.

If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business or our market, or if they adversely change their recommendations regarding our common shares, the trading price or trading volume of our common shares could decline.

The trading market for common shares will be influenced in part by the research and reports that securities or industry analysts may publish about us, our business, our market or our competitors. If one or more securities analysts initiate research with an unfavorable rating or downgrade our common shares, provide a more favorable recommendation about our competitors or publish inaccurate or unfavorable research about our business, our common shares price would likely decline. If few securities analysts commence coverage of us, or if one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets and demand for our securities could decrease, which in turn could cause the price and trading volume of our common shares to decline.

The outstanding Series 1 Preferred Shares, and any issuance of preferred shares could make it difficult for another company to acquire us or could otherwise adversely affect holders of our common shares, which could depress the price of our common shares.

Our board of directors has the authority to issue preferred shares and to determine the preferences, limitations and relative rights of preferred shares and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our shareholders. The Company currently has 8,905,638 Series 1 Preferred Shares issued and outstanding, and may issue additional preferred shares in the future. Our preferred shares may be issued with liquidation, dividend and other rights superior to the rights of our common shares. The potential issuance of preferred shares may delay or prevent a change in control, discourage bids for our common shares at a premium over the market price and adversely affect the market price and other rights of the holders of our common shares.

Our constating documents permit us to issue an unlimited number of common shares without additional shareholder approval.

Our Articles permit us to issue an unlimited number of common shares. We anticipate that we will, from time to time, issue additional common shares in the future. Subject to the requirements of the TSX and Nasdaq, we will not be required to obtain the approval of shareholders for the issuance of additional common shares. Any further issuances of common shares will result in immediate dilution to existing shareholders and may have an adverse effect on the value of their shareholdings.

Raising additional capital may cause dilution to our shareholders, including purchasers of common shares in this offering, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through equity offerings, debt financings, or other capital sources, including potential collaborations, licenses and other similar arrangements. We do not have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest may be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common shareholder. We are authorized to issue an unlimited number of common shares. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Such restrictions could adversely impact our ability to conduct our operations and execute our business plan.

If we raise additional funds through future collaborations, licenses and other similar arrangements, we may be required to relinquish valuable rights to our future revenue streams, product candidates, research programs, intellectual property or proprietary technology, or grant licenses on terms that may not be favorable to us and/or that may reduce the value of our common shares. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed or on terms acceptable to us, we would be required to delay, limit, reduce or terminate our product development or future commercialization efforts, or grant rights to develop and market product candidates that we might otherwise prefer to develop and market ourselves, or on less favorable terms than we would otherwise choose.

We have warrants, Series 1 Preferred Shares convertible into common shares, and shares of a subsidiary exchangeable for common shares outstanding, which in each case, if exercised, converted or exchanged, respectively, could cause dilution to existing shareholders.

In addition, we have outstanding stock options representing a right to receive common shares upon vesting and the exercise of the stock options, outstanding warrants that are exercisable for common shares, and Series 1 Preferred Shares that are convertible into common shares. Pursuant to the terms of our amended and restated

S-23

Table of Contents

stock option plan, the number of common shares we may grant under such plan will automatically increase upon the closing of this offering such that the aggregate number of common shares that may be reserved for issuance under the stock option plan equals 18.5% of our outstanding common shares. Furthermore, Eupraxia Pharma Inc., our subsidiary, has non-voting Class B shares outstanding that are exchangeable into common shares at any time at the election of the holder. The exercise of stock options and warrants, the conversion of Series 1 Preferred Shares into common shares, and the exchange of such Class B shares and the subsequent resale of such common shares in the public market, could adversely affect the prevailing market price of the common shares and our ability to raise equity capital in the future at a time and price which we deem appropriate. We may also enter into commitments in the future which would require the issuance of additional common shares and we are expected to grant additional stock options. Any common shares issuances from our treasury will result in immediate dilution to existing shareholders’ percentage interest in us.

Our common shares may have limited liquidity.

Our shareholders may be unable to sell significant quantities of common shares into the public trading markets without a significant reduction in the price of their common shares, or at all. There can be no assurance that there will be sufficient liquidity of the common shares on the trading market, and that we will continue to meet the listing requirements of the TSX, maintain a listing on Nasdaq, or achieve or maintain a listing on any other securities exchange.

We cannot assure you that an active market will develop for common shares on Nasdaq.

Our common shares are listed on the TSX under the symbol “EPRX”, and were approved for listing on Nasdaq on April 5, 2024, under the symbol “EPRX”. Prior to this listing, there had been no prior public trading market for the common shares on Nasdaq. We cannot assure you that our listing of the common shares on Nasdaq will be maintained, or that an active trading market for the common shares will develop on Nasdaq or elsewhere or, if developed, that any market will be sustained. Accordingly, we cannot assure you of the liquidity of any trading market, your ability to sell the common shares when desired or the prices that you may obtain for your shares.

U.S. investors may not be able to obtain enforcement of civil liabilities against us.

The enforcement by investors of civil liabilities under the U.S. federal or state securities laws may be affected adversely by the fact that we are governed by the Business Corporations Act (British Columbia), that the majority of our officers and directors are residents of Canada or otherwise reside outside the United States, and that all, or a substantial portion of their assets and a substantial portion of our assets, are located outside the United States. It may not be possible for investors to effect service of process within the United States on certain of our directors and officers or enforce judgments obtained in the United States courts against us or certain of our directors and officers based upon the civil liability provisions of United States federal securities laws or the securities laws of any state of the United States.

There is some doubt as to whether a judgment of a U.S. court based solely upon the civil liability provisions of U.S. federal or state securities laws would be enforceable in Canada against us or our directors and officers. There is also doubt as to whether an original action could be brought in Canada against us or our directors and officers to enforce liabilities based solely upon U.S. federal or state securities laws.

As a foreign private issuer, we are subject to different U.S. securities laws and rules than a domestic U.S. issuer, which may limit the information publicly available to our U.S. shareholders.

We are a foreign private issuer under applicable U.S. federal securities laws and, therefore, we are not required to comply with all the periodic disclosure and current reporting requirements of the U.S. Exchange Act, and related rules and regulations, applicable to U.S. domestic issuers. We do not file all of the same reports that a U.S. domestic issuer would file with the SEC, although we are required to file with or furnish to the SEC the

S-24

Table of Contents

continuous disclosure documents that we are required to file in Canada under Canadian securities laws. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short swing” profit recovery provisions of Section 16 of the U.S. Exchange Act. Therefore, our shareholders may not know on as timely a basis when our officers, directors and principal shareholders purchase or sell common shares as the reporting periods under the corresponding Canadian insider reporting requirements are longer. In addition, as a foreign private issuer, we are exempt from the proxy rules under the U.S. Exchange Act.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses to us.

In order to maintain our current status as a foreign private issuer, a majority of our common shares must be either directly or indirectly owned by non-residents of the United States unless we also satisfy one of the additional requirements necessary to preserve this status. We may in the future lose our foreign private issuer status if a majority of the common shares are held in the United States and we fail to meet the additional requirements necessary to avoid loss of foreign private issuer status. The regulatory and compliance costs to us under U.S. federal securities laws as a U.S. domestic issuer may be significantly more than the costs we incur as a Canadian foreign private issuer eligible to use the MJDS. If we are not a foreign private issuer, we would not be eligible to use the MJDS or other foreign issuer forms and would be required to file periodic and current reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. We may lose the ability to rely upon exemptions from Nasdaq corporate governance requirements that are available to foreign private issuers.

U.S. holders of our shares may suffer adverse tax consequences if we are characterized as a passive foreign investment company.

We may be treated as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes, in which case U.S. holders would be subject to a special, generally adverse tax regime. Generally, for any taxable year in which 75% or more of our gross income is passive income, or at least 50% of the value of our assets (as determined under applicable U.S. Treasury Regulations, which may be determined in part by the market value of our shares, which is subject to change) are held for the production of, or produce, passive income, we would be characterized as a PFIC for U.S. federal income tax purposes. We will be treated as owning the proportionate share of the assets and earning the proportionate share of the income of any other corporation, the equity of which we own, directly or indirectly, 25% or more (by value). We have not completed a formal assessment of our status as a PFIC for 2024 or for the current taxable year; however, based on our gross income and gross assets, we believe that we were a PFIC for the taxable year ending December 31, 2024, and may be a PFIC for subsequent taxable years. Our status as a PFIC is a fact-intensive determination, and we cannot provide any assurance regarding our PFIC status for the current taxable year or future taxable years.

If we are a PFIC for any year, U.S. holders of our shares may suffer adverse tax consequences. If we are a PFIC in any year with respect to which a U.S. holder owns our shares, we will continue to be treated as a PFIC with respect to such U.S. holder in all succeeding years during which the U.S. holder owns our shares, whether or not we remain a PFIC unless such U.S. holder makes a qualified electing fund or mark-to-market election. Gains realized by non-corporate U.S. holders on the sale of our shares would be taxed as ordinary income, rather than as capital gain, and the preferential tax rate applicable to dividends received on our common shares would be lost. Interest charges would also be added to taxes on gains and dividends realized by all U.S. holders. U.S. holders should consult their own tax advisors with respect to their particular circumstances. In order to make either a qualified electing fund or mark-to-market election certain requirements must be met. We cannot provide any assurances that these requirements will be met in order for U.S. holders to be able to make a qualified electing fund or mark-to-market election. U.S. holders should consult their tax advisors regarding the potential application of these rules to their investment in our common shares.

The PFIC rules, including the rules governing any elections that may potentially be made by a U.S. Holder, are extremely complex. Each U.S. holder should consult its own tax advisor regarding our potential PFIC status and

S-25

Table of Contents

how the PFIC rules (including elections that may be available thereunder) would affect the U.S. federal income tax consequences of the acquisition, ownership and disposition of our common shares.

If a U.S. holder is treated as owning at least 10% of our common shares, such U.S. holder may be subject to adverse U.S. federal income tax consequences.

If a U.S. holder is treated as owning, directly, indirectly or constructively, at least 10% of the value or voting power of our common shares, such U.S. holder may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group, if any. Generally, a non-U.S. corporation is deemed as a controlled foreign corporation if more than 50% of its stock (by voting power or value) is owned (directly, indirectly or constructively) by U.S. shareholders. We will generally be classified as a controlled foreign corporation if more than 50% of our outstanding shares, measured by reference to voting power or value, are owned (directly, indirectly or by attribution) by U.S. shareholders. In addition, since our group includes one or more U.S. subsidiaries, certain of our non-U.S. subsidiaries could be treated as controlled foreign corporations, regardless of whether we are treated as a controlled foreign corporation. If we or any of our non-U.S. subsidiaries are treated as controlled foreign corporations, a U.S. shareholder would be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income,” “global intangible low-taxed income” and investments in U.S. property by the controlled foreign corporation, regardless of whether we make any distributions, and generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a U.S. shareholder of a U.S. corporation. In addition, failure to comply with certain reporting obligations may subject a U.S. shareholder to monetary penalties and may prevent the statute of limitations with respect to such shareholder’s U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist our investors in determining whether any of our non-U.S. subsidiaries are treated as a controlled foreign corporation or whether such investor is treated as a U.S. shareholder with respect to any of such controlled foreign corporations. Further, we cannot provide any assurances that we will furnish to any U.S. shareholder information that may be necessary to comply with the reporting and tax paying obligations described in this risk factor. U.S. holders should consult their tax advisors regarding the potential application of these rules to their investment in our common shares.

DESCRIPTION OF THE BUSINESS

Overview of the Company

We are a clinical-stage biotechnology company seeking to leverage our proprietary DiffuSphere^™ technology to optimize drug delivery for applications with significant unmet medical need. Each of our product candidates is designed to improve patient benefit by providing more prolonged activity than currently available treatments, combined with an improved PK and related safety profile and precisely targeted local delivery. We believe a product with this profile could offer the dual potential of providing long-lasting treatment while minimizing tolerability complications in target and non-target tissues. Our strategy is to develop a portfolio of product candidates based on this delivery technology.

We currently have two distinct clinical development programs, one targeting EoE and the second targeting chronic OA pain in the knee. Both programs are broadly based upon the same API, fluticasone propionate. The injectable drug is dispensed together with a “vehicle” diluent specifically designed for the target delivery modality and co-administered with the API. For our ongoing clinical studies, we are using the same underlying API and extended-release formulation. In the future, we anticipate that therapeutic targets will be differentiated by dosing levels, vehicle and delivery methods and will be distinct product candidates. The product candidate that is being developed specifically for submucosal injections in the GI tract with an initial indication of EoE is referred to as EP-104GI, and the product candidate that is being developed for IA injections with an initial indication of knee OA is referred to as EP-104IAR. EP-104 is intended to refer to the extended-release fluticasone propionate encapsulated with the DiffuSphere^™ technology, which is used in the formulation of both EP-104GI and EP-104IAR.

We are currently conducting a Phase 2 clinical trial with EP-104GI in Canada, the Netherlands, Australia, New Zealand, the United Kingdom and Switzerland. The first part of the RESOLVE trial is a dose-escalation study evaluating the safety, tolerability and effectiveness of EP-104GI in adults with histologically confirmed active EoE. The treatment is administered as a single dose via 4-20 injections into the esophageal wall, with dose escalations modifying either the dose per site and/or number of sites. Lower dose cohorts (4 to 30 mg total dose) were followed out to 24 weeks, while higher dose cohorts (up to 160 mg total dose) will be followed out to 52 weeks.

Throughout 2025, the Company announced interim data from the RESOLVE Phase 1b/2a clinical trial evaluating the safety and efficacy of EP-104GI for the treatment of EoE. The data to date from all cohorts suggest that EP-104GI continues to be released into the esophagus at a relatively constant rate from week 2 through month 12.

In September 2025, the Company announced additional clinical data from the ongoing RESOLVE Phase 1b/2a trial, including the first results for 12 months follow-up after treatment with EP-104GI. These results showed that two of three patients in Cohort 5 (48 mg total dose; 4 mg per site) remained in clinical remission for one year. The Company observed that all dose cohorts evaluated through nine months (cohorts 5 and 6) maintained what the Company believes to be clinically meaningful improvements in tissue health, similar to that observed at 3 months as measured by the EoEHSS.

The Company has also observed a general trend in which patients receiving higher doses of EP-104GI and exhibiting higher plasma levels appear to show greater histologic and symptomatic improvements. This trend was also observed in the four-week data from patients (cohorts 8 and 9) receiving the 120 mg or 160 mg total dose (administered across 20 injection sites). To date, no SAEs, nor any reported cases of oral or gastrointestinal candidiasis, have been observed in the trial.

On July 8, 2025, we announced dosing of the first patient in a Phase 2b, randomized, placebo-controlled, dose-optimization portion of the RESOLVE trial. The Phase 2b portion will enroll a minimum of 60 participants randomized in a 1:1:1 ratio to receive one of two doses of EP-104GI or placebo. After six months, eligible patients initially dosed with placebo may elect to receive EP-104GI. The study is currently enrolling patients with the first clinical dose of 120 mg (6 mg per site x 20 sites).

Table of Contents

We also received pre-IND feedback from the FDA on December 3, 2024, to clarify early phase program requirements for conducting studies in the United States. We intend to continue development of EP-104GI through the ongoing clinical trial and any subsequent trials and other testing required by the FDA for submission of an NDA to obtain approval for marketing in the United States. We intend to evaluate the possibility of identifying a corporate partner to help with the development of EP-104GI outside of the United States.

We have successfully completed a Phase 2b clinical trial with EP-104IAR in knee OA, and in January 2024, we held a meeting with the FDA to determine the late-phase program requirements for an NDA submission and potential approval in the United States. We reached agreement with the FDA on the clinical and non-clinical programs required to achieve marketing authorization. We believe the product candidate’s future success will depend on late-phase development and commercialization expertise and will require significant resources. We are currently evaluating funding alternatives for the continued development of EP-104IAR, including potential partnership opportunities and intend to modulate investment levels pending the outcomes. We are undertaking certain preclinical and manufacturing activities as well as Phase 3 planning and preparation related to EP-104IAR to ensure continuity of the project, but we intend to wait until we have funding needs addressed before committing to additional significant spend for this program.

Further information regarding the business of the Company can be found in our Annual Information Form and Interim MD&A, and the other documents incorporated by reference into this prospectus supplement available on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

USE OF PROCEEDS

We estimate that the net proceeds of the sale of common shares in this offering will be approximately US$64.2 million, or approximately US$74.0 million if the underwriters exercise in full their option to purchase additional common shares, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

The Company intends to use the net proceeds from this offering primarily for the continued advancement of its product pipeline, including the completion of ongoing preclinical studies and clinical trials, regulatory submissions, and associated commercial preparation and manufacturing scale-up activities. A portion of the proceeds will also be allocated to research and development of additional pipeline candidates, business development initiatives, and general corporate purposes, which may include but are not limited to employee salaries, working capital, leases for facilities, administrative expenses, and capital expenditures. The Company may also use a portion of the proceeds to expand its intellectual property portfolio and strengthen its corporate infrastructure to support future growth.

We intend to allocate net proceeds of this offering as follows (without giving effect to the exercise of the option to purchase additional common shares granted to the underwriters):

Purpose		Estimated Amount (US$)
Phase 2 development of EP-104GI		US$28.4 million
Nonclinical Studies Enabling Phase 3 and NDA Patient Pool Expansion		US$5.0 million
Additional Phase 2 trial in GI Indications for EP-104GI		US$7.1 million
Pipeline		US$3.4 million

We intend to allocate the remaining net proceeds to working capital and other general corporate purposes. Based on our current plans, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will be sufficient to fund our planned operations until the second half of 2027, assuming the full exercise of the EPRX.WT.A warrants prior to their April 2026 expiry, which we believe will enable us to conduct the activities identified above. We will utilize the services of CROs to conduct clinical trials and the CROs will source vendors for various components of the trials.

The expected use of the net proceeds from the offering set out above represents our intentions based upon our current plans and business conditions. The amounts and timing of our clinical and preclinical expenditures and the extent of clinical development may vary significantly depending on numerous factors, including the status, results and timing of our current clinical trials and clinical trials we may commence in the future, the product approval process with applicable regulatory agencies, any collaborations we may enter into with third parties and any unforeseen cash needs. We could use our capital resources sooner than we currently expect. See “Risk Factors” in this prospectus supplement and the shelf prospectus and the documents incorporated by reference herein and therein.

Moreover, our estimates of the costs to fund our clinical trials are based on the current or anticipated designs of such clinical trials. If we were to modify the design of any of these trials to, for instance, increase the number of patients in the trials, our costs to fund such trials could increase. As a result, we cannot predict with any certainty all of the particular uses for the net proceeds or the amounts that we will actually spend on the uses set forth above. Accordingly, our management will have broad discretion in the application of the net proceeds, and investors will be relying on the judgment of our management regarding the application of the net proceeds of this offering. Pending these uses, we plan to invest these net proceeds in treasury bills, bonds, notes and other indebtedness issued or guaranteed by Canada, term deposits, banker’s acceptances, guaranteed investment

S-33

Table of Contents

certificates or deposit-based investments including, but not limited to, interest savings accounts. The goal with respect to the investment of these net proceeds is capital preservation and liquidity so that such funds are readily available to fund our operations.

Based on our current plans, we will require additional capital to advance EP-104GI through pivotal clinical trials, to advance development of any additional product candidates and to commercialize any of our product candidates if we receive regulatory approval, including EP-104IAR. Due to the numerous risks and uncertainties associated with product development, including risks and uncertainties with respect to successful enrollment and completion of clinical trials, at this time we cannot reasonably estimate the amount of additional funding that will be necessary to complete the clinical development of any of our product candidates. Accordingly, we will be required to obtain further funding through public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources.

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement, dated September 22, 2025, between us and Cantor Fitzgerald & Co., 110 East 59^th Street, 6^th Floor, New York, New York 10022, as representative of the underwriters named below (the “Representative”), we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the number of common shares shown opposite its name below:

Underwriter		Number of Shares
Cantor Fitzgerald & Co.			7,954,546
LifeSci Capital LLC			4,136,364
Bloom Burton Securities Inc.			636,363
Total			12,727,273

The underwriting agreement provides that the obligations of the several underwriters are subject to certain conditions precedent such as the receipt by the Representative of officers’ certificates and legal opinions and approval of certain legal matters by their counsel. The underwriting agreement provides that the underwriters will purchase all of the common shares if any of them are purchased. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the common shares subject to their acceptance of the common shares from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. In addition, the underwriters have advised us that they do not intend to confirm sales to any account over which they exercise discretionary authority.

Neither Cantor Fitzgerald & Co. nor LifeSci Capital LLC is a registered dealer in any Canadian jurisdiction and, accordingly, neither is permitted to and neither will, directly or indirectly, advertise or solicit offers to purchase any of the common shares offered hereby in Canada. Cantor Fitzgerald Canada Corporation and Bloom Burton Securities Inc. will solicit offers to purchase the common shares offered hereby in Canada.

Option to Purchase Additional Shares

We have granted to the underwriters an option, exercisable 30 days from the date of the underwriting agreement, to purchase, from time to time, in whole or in part, up to an aggregate of 1,909,090 common shares from us at the public offering price set forth on the cover page of this prospectus supplement, less underwriting discounts and commissions. If the underwriters exercise this option, each underwriter will be obligated, subject to certain conditions, to purchase a number of additional common shares proportionate to that underwriter’s initial purchase commitment as indicated in the table above. A purchaser who acquires common shares forming part of the underwriters’ over-allocation position acquires those common shares under this prospectus supplement, regardless of whether the over-allocation position is ultimately filled through the exercise of the option to purchase additional common shares or secondary market purchases.

Commission and Expenses

The underwriters have advised us that they propose to offer the common shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers, which may include the underwriters, at that price less a concession not in excess of US$0.2310 per common share. The public offering price was determined by negotiation between the Company and the underwriters.

S-36

Table of Contents

• enter into any swap, forward, hedge or other agreement or transaction that transfers, in whole or in part, the economic consequence of ownership of common shares, or securities exchangeable or exercisable for or convertible into common shares, or

• publicly announce an intention to do any of the foregoing.

The restrictions in the immediately preceding paragraph do not apply in certain circumstances, including, and subject to certain additional restrictions:

(A) with respect to us:

(i) effecting the transactions contemplated the underwriting agreement; and

(ii) issuing common shares or options to purchase common shares, or issuing common shares upon exercise of options, warrants or rights to purchase common shares pursuant to existing obligations described in this prospectus supplement or the shelf prospectus (including the documented incorporated by reference herein and therein);

(B) with respect to our executive officers and directors:

(i) the transfer of securities as a bona fide gift or gifts;

(ii) the transfer of securities to any trust for the direct or indirect benefit of the officer or director or the immediate family of the officer or director (where “immediate family” means any relationship by blood, marriage or adoption, not more remote than first cousin);

(iii) the transfer of securities pursuant to a qualified domestic order or in connection with a divorce settlement;

(iv) the transfer of securities to any nominee or custodian where there is no change in beneficial ownership for bona fide tax planning purposes including, but not limited to, transfers to a registered retirement savings plan or to an affiliate;

(v) the transfer of securities by will or intestate succession to the legal representative, heir, beneficiary or immediate family of the undersigned upon the death of the undersigned; or

(vi) the receipt of a grant of stock options and other similar issuances pursuant to the omnibus incentive plan of the Company and other share compensation arrangements described herein and outstanding as of the date hereof, or the conversion, exercise or exchange of any convertible, exercisable or exchangeable securities described in herein and outstanding as of the date hereof or upon exercise of stock options granted in accordance with the foregoing.

The Representative may, in its sole discretion and at any time or from time to time before the termination of the 90-day period release all or any portion of the securities subject to lock-up agreements.

Market Making, Stabilization and Other Transactions

The underwriters may make a market in the common shares as permitted by applicable laws and regulations. However, the underwriters are not obligated to do so, and the underwriters may discontinue any market-making activities at any time without notice in their sole discretion. Accordingly, no assurance can be given as to the liquidity of the trading market for the common shares, that you will be able to sell any of the common shares held by you at a particular time or that the prices that you receive when you sell will be favorable.

The underwriters have advised us that they, pursuant to Regulation M under the Exchange Act, may engage in short sale transactions, stabilizing transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering. These activities may have the effect of stabilizing or maintaining the market price of the common shares at a level above that which might otherwise prevail in the open market. Establishing short sales positions may involve either “covered” short sales or “naked” short sales.

S-37

Table of Contents

“Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional common shares in this offering. The underwriters may close out any covered short position by either exercising their option to purchase additional common shares or purchasing our common shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option to purchase additional shares.

“Naked” short sales are sales in excess of the option to purchase additional common shares. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common shares in the open market after pricing that could adversely affect investors who purchase in this offering.

A stabilizing bid is a bid for the purchase of common shares on behalf of the underwriters for the purpose of fixing or maintaining the price of the common shares. A syndicate covering transaction is the bid for or the purchase of common shares on behalf of the underwriters to reduce a short position incurred by the underwriters in connection with the offering. Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common shares or preventing or retarding a decline in the market price of our common shares. As a result, the price of our common shares may be higher than the price that might otherwise exist in the open market. A penalty bid is an arrangement permitting the underwriters to reclaim the selling concession otherwise accruing to a syndicate member in connection with the offering if the common shares originally sold by such syndicate member are purchased in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.

Neither we, nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common shares. The underwriters are not obligated to engage in these activities and, if commenced, may end any of these activities at any time.

Passive Market Making

The underwriters may also engage in passive market making transactions in our common shares on Nasdaq in accordance with Rule 103 of Regulation M during a period before the commencement of offers or sales of our common shares in this offering and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common shares to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriters are not required to engage in passive market making and, if commenced, may end passive market making activities at any time.

Electronic Distribution

A prospectus in electronic format may be made available by e-mail or on the websites or through online services maintained by one or more of the underwriters, selling group members (if any) or their affiliates. The underwriters may agree with us to allocate a specific number of common shares for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus in electronic format, the information on the underwriters’ web sites and any information contained in any other web site maintained by any of the underwriters is not part of this prospectus supplement, has not been approved and/or endorsed by us or the underwriters and should not be relied upon by investors.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is, as of the date hereof, a general summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations promulgated thereunder (collectively, the “Tax Act”), generally applicable to a holder who acquires common shares as beneficial owner and who for the purposes of the Tax Act and at all relevant times: (i) deals at arm’s length with the Company and each of the Underwriters; (ii) is not affiliated with the Company or any of the Underwriters; (iii) and will acquire and hold common shares as capital property (each, a “Holder”). The common shares will generally be considered to be capital property to a Holder unless the Holder holds or uses the common shares or is deemed to hold or use the common shares in the course of carrying on a business of trading or dealing in securities or has acquired them or is deemed to have acquired them in a transaction or transactions considered to be an adventure or concern in the nature of trade.

This summary is not applicable to a Holder: (i) that is a “financial institution” for purposes of the mark-to-market rules contained in the Tax Act; (ii) that is a “specified financial institution” as defined in the Tax Act; (iii) an interest in which is or would be a “tax shelter investment” as defined in the Tax Act; (iv) that has elected to report its “Canadian tax results”, as defined in the Tax Act, in a currency other than Canadian currency; (v) that has entered or will enter into, with respect to the common shares, a “derivative forward agreement” or a “synthetic disposition arrangement” (as these terms are defined in the Tax Act); (vi) that will receive dividends on common shares under or as part of a “dividend rental arrangement” (as defined in the Tax Act); or (vii) that is exempt from tax under the Tax Act. In addition, this summary does not address the deductibility of interest by a holder of common shares that has borrowed money or otherwise incurred debt in connection with the acquisition of common shares. Any such Holder to which this summary does not apply should consult their own tax advisor with respect to an investment in common shares.

Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada (or does not deal at arm’s length for purposes of the Tax Act with a corporation resident in Canada) that is, or becomes as part of a transaction or series of transactions or events that includes the acquisition of common shares, controlled by a non-resident corporation, individual, trust, or group of the foregoing that do not deal with each other at arm’s length for the purposes of the “foreign affiliate dumping” rules in section 212.3 of the Tax Act. Such Holders should consult their own tax advisors with respect to an investment in common shares.

This summary is based upon the facts set out in this prospectus supplement, the provisions of the Tax Act in force as of the date hereof, and counsel’s understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (“CRA”) published in writing and made publicly available by the CRA prior to the date hereof. This summary takes into account all specific proposals to amend the Tax Act that have been publicly and officially announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”) and assumes that the Tax Proposals will be enacted substantially in the form proposed, although no assurance can be given that the Tax Proposals will be enacted in their current form or at all.

This summary does not otherwise take into account or anticipate any changes in law or in the administrative policies or assessing practices of the CRA, whether by way of judicial, legislative or governmental decision or action. This summary is not exhaustive of all possible Canadian federal income tax considerations and does not take into account other federal or any provincial, territorial or foreign income tax legislation or considerations, which may differ materially from those described in this summary.

This summary is not exhaustive of all possible Canadian federal income tax considerations of acquiring common shares. This summary is of a general nature only and is not, and is not intended to be, and should not be construed to be, legal, business or tax advice to any particular Holder, and no representations concerning the tax consequences to any particular Holder are made. The tax consequences of acquiring,

S-44

Table of Contents

holding and disposing of common shares will vary according to the Holder’s particular circumstances. Holders should consult their own tax advisors regarding the tax considerations applicable to them having regard to their particular circumstances.

Currency Conversion

Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of our common shares (including dividends, adjusted cost base and proceeds of disposition) must be converted into Canadian dollars based on the exchange rates as determined in accordance with the Tax Act.

Taxation of Resident Holders

The following portion of the summary applies to a Holder who, for the purposes of the Tax Act and any applicable income tax treaty or convention, is, or is deemed to be, resident in Canada at all relevant times (a “Resident Holder”).

A Resident Holder whose common shares might not otherwise constitute capital property may be entitled to make, in certain circumstances, an irrevocable election permitted by subsection 39(4) of the Tax Act to have the common share, and every other “Canadian security” as defined in the Tax Act, held by such Resident Holder in the taxation year of the election and in all subsequent taxation years, treated as capital property. Resident Holders should consult their own tax advisors regarding this election.

Taxation of Dividends

Dividends received or deemed to be received on our common shares by a Resident Holder will be included in computing a Resident Holder’s income for the year. In the case of a Resident Holder who is an individual (including certain trusts) such dividends will be subject to the gross-up and dividend tax credit rules applicable to “taxable dividends” received by an individual from a “taxable Canadian corporation” (each as defined in the Tax Act), including the enhanced gross-up and dividend tax credit for “eligible dividends” (as defined in the Tax Act) properly designated as such by the Corporation in accordance with the Tax Act. There may be limitations on the ability of the Corporation to designate dividends as eligible dividends.

Dividends received or deemed to be received on the common shares by a Resident Holder that is a corporation must be included in computing its income and will generally be deductible in computing its taxable income, subject to all restrictions under the Tax Act. In certain circumstances, subsection 55(2) of the Tax Act will treat a taxable dividend received (or deemed to be received) by a Resident Holder that is a corporation as proceeds of disposition or a capital gain. Resident Holders that are corporations should consult their own tax advisors having regard to their own circumstances.

A Resident Holder that is a “private corporation” or “subject corporation” (as such terms are defined in the Tax Act) may be liable to pay a tax (refundable in certain circumstances) under Part IV of the Tax Act on dividends received or deemed to be received on our common shares to the extent that such dividends are deductible in computing the Resident Holder’s taxable income for the year. A “subject corporation” is generally a corporation (other than a private corporation) resident in Canada and controlled directly or indirectly by or for the benefit of an individual (other than a trust) or a related group of individuals (other than trusts).

Dispositions of Common Shares

A Resident Holder who disposes of, or is deemed to have disposed of, a common share (other than a disposition to the Corporation that is not a sale in the open market in the manner in which shares are normally purchased by any member of the public in the open market) will realize a capital gain (or a capital loss) equal to the amount by which the proceeds of disposition in respect of the common share exceed (or are exceeded by) the aggregate of the adjusted cost base to the Resident Holder of such common share immediately before the disposition or deemed disposition and any reasonable expenses incurred for the purpose of making the disposition. The adjusted

S-45

Table of Contents

cost base to a Resident Holder of a common share will be determined by averaging the cost of that common share with the adjusted cost base (determined immediately before the acquisition of the common share) of any other common shares which are held as capital property at that time by the Resident Holder. The tax treatment of capital gains and capital losses is discussed in greater detail below under the subheading “Capital Gains and Losses”.

Capital Gains and Losses

Generally, one-half of any capital gain (a “taxable capital gain”) realized by a Resident Holder must be included in the Resident Holder’s income for the taxation year in which the disposition occurs. Subject to and in accordance with the provisions of the Tax Act, one-half of any capital loss incurred by a Resident Holder (an “allowable capital loss”) must be deducted from taxable capital gains realized by the Resident Holder in the taxation year in which the disposition occurs. Allowable capital losses in excess of taxable capital gains for the taxation year of disposition generally may be carried back and deducted in the three preceding taxation years or carried forward and deducted in any subsequent year against taxable capital gains (but not against other income) realized in such years, in the circumstances and to the extent provided in the Tax Act.

A capital loss realized on the disposition of a common share by a Resident Holder that is a corporation may in certain circumstances be reduced by the amount of dividends which have been previously received or deemed to have been received by the Resident Holder on the common share, or a share substituted for such share, as applicable, to the extent and in the circumstances specified by the Tax Act. Similar rules may apply where a common share is owned by a partnership or trust of which a corporation, trust or partnership is a member or beneficiary, as applicable. Resident Holders to whom these rules may be relevant should consult their own tax advisors.

Additional Refundable Tax

A Resident Holder that: (i) throughout the relevant taxation year, is a “Canadian-controlled private corporation” (as defined in the Tax Act), or (ii) at any time in the relevant taxation year, is a “substantive CCPC” ( as defined in the Tax Act), may be liable to pay an additional tax (refundable in certain circumstances) on its “aggregate investment income” (as defined in the Tax Act) for the year, including any taxable capital gains and dividends or deemed dividends that are not deductible in computing the Resident Holder’s taxable income. Resident Holders to whom these rules may be relevant should consult their own tax advisors.

Minimum Tax

Individuals and trusts, other than certain specified trusts, may be subject to a minimum tax. Generally, dividends received or deemed to be received on the common shares and capital gains realized on the disposition of common shares may result in a Resident Holder who is an individual (including certain trusts) being liable for minimum tax. Such Resident Holders should consult with their own tax advisors in this regard.

Taxation of Non-Resident Holders

This portion of the summary is applicable to a Holder who, at all relevant times, is neither resident in Canada nor deemed to be resident in Canada for purposes of the Tax Act and any applicable income tax treaty or convention, and who does not use or hold (and is not deemed to use or hold) the common shares in the course of carrying on a business (including an adventure or concern in the nature of trade) in Canada, or otherwise in connection with a business carried in Canada (a “Non-Resident Holder”). The term “U.S. Holder,” for the purposes of this summary, means a Non-Resident Holder who, for purposes of the Canada-United States Tax Convention (1980), as amended (the “Convention”), is at all relevant times a resident of the United States and is a “qualifying person” within the meaning of the Convention eligible for the full benefits of the Convention. In some circumstances, persons deriving amounts through fiscally transparent entities (including limited liability

S-46

Table of Contents

companies) may be entitled to benefits under the Convention. U.S. Holders are urged to consult their own tax advisors to determine their entitlement to benefits under the Convention and related compliance requirements based on their particular circumstances.

Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on business in Canada and elsewhere or is an “authorized foreign bank” (as defined in the Tax Act). Such Non-Resident Holders should consult their own tax advisors with respect to an investment in the common shares.

Taxation of Dividends

Dividends paid or credited or deemed to be paid or credited to a Non-Resident Holder by us on any common shares will be subject to withholding tax under the Tax Act at the rate of 25% on the gross amount of the dividend unless such rate is reduced by the terms of an applicable income tax treaty or convention. Such rate is generally reduced under the Convention to 15% if the beneficial owner of such dividend is a U.S. Holder. The rate of withholding tax is generally further reduced to 5% if the beneficial owner of such dividend is a U.S. Holder that is a company that owns, directly or indirectly, at least 10% of our voting stock. The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (the “MLI”) of which Canada is a signatory, affects many of Canada’s tax treaties (but not the Convention), including the ability to claim benefits thereunder. Non-Resident Holders should consult their own tax advisors to determine their entitlement to relief under an applicable income tax treaty or convention.

Disposition of Common Shares

A Non-Resident Holder will not be subject to tax under the Tax Act in respect of any capital gain realized by such Non-Resident Holder on a disposition or deemed disposition of a common share nor will capital losses arising therefrom be recognized under the Tax Act, unless the common share constitutes “taxable Canadian property” (as defined in the Tax Act) of the Non-Resident Holder at the time of disposition and the Non-Resident Holder is not entitled to relief under an applicable income tax treaty or convention (including as a result of the application of the MLI).

Provided the common shares are listed on a “designated stock exchange”, as defined in the Tax Act (which currently includes the TSX and Nasdaq) at the time of disposition or deemed disposition, our common shares will generally not constitute taxable Canadian property of a Non-Resident Holder at that time, unless at any time during the 60-month period immediately preceding the disposition, the following two conditions are satisfied concurrently: (i) any one or combination of (a) the Non-Resident Holder; (b) persons with whom the Non-Resident Holder did not deal at arm’s length (for the purposes of the Tax Act); or (c) partnerships in which the Non-Resident Holder or a person described in (b) holds a membership interest directly or indirectly through one or more partnerships, owned 25% or more of the issued shares of any class or series of our shares; and (ii) more than 50% of the fair market value of the common shares was derived, directly or indirectly, from one or any combination of real or immovable property situated in Canada, “Canadian resource properties”, “timber resource properties” (each as defined in the Tax Act), and options in respect of, interests in, or, for civil law, rights in, any such properties (whether or not the property exists). Notwithstanding the foregoing, in certain circumstances set out in the Tax Act, our common shares could be deemed to be taxable Canadian property.

If our common shares are or are deemed to be taxable Canadian property of a Non-Resident Holder, any capital gain realized on the disposition or deemed disposition of such common shares may not be subject to tax under the Tax Act pursuant to the terms of an applicable income tax treaty or convention. Non-Resident Holders whose common shares are, or may be, taxable Canadian property should consult their own tax advisors for advice having regard to their particular circumstances.

S-47

Table of Contents

In the event that a common share constitutes taxable Canadian property of a Non-Resident Holder and any capital gain that would be realized on the disposition or deemed disposition thereof is not exempt from tax under the Tax Act pursuant to an applicable income tax convention or treaty (including as a result of the application of the MLI), the income tax consequences discussed under “Residents of Canada—Dispositions of Common Shares” and “Residents of Canada—Capital Gains and Losses” will generally apply to the Non-Resident Holder.

A Non-Resident Holder contemplating a disposition of common shares that may constitute taxable Canadian property should consult a tax advisor prior to such disposition regarding the tax and compliance considerations that may be relevant to them.

CERTAIN MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR U.S. HOLDERS

Subject to the limitations and qualifications stated herein, this discussion sets forth material U.S. federal income tax considerations relating to the ownership and disposition by U.S. Holders (as hereinafter defined) of the common shares. The discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed U.S. Treasury Regulations thereunder, published rulings and court decisions, all as currently in effect changed in a material and adverse manner at any time, and any such change could be applied retroactively. This summary does not discuss the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis.

No opinion from legal counsel or ruling from the Internal Revenue Service (the “IRS”) has been requested, or will be obtained, regarding the U.S. federal income tax considerations applicable to U.S. Holders as discussed in this summary. This summary is not binding on the IRS, and the IRS is not precluded from taking a position that is different from, and contrary to, the positions taken in this summary. In addition, because the authorities on which this summary is based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the positions taken in this summary.

This summary applies only to U.S. Holders that acquire common shares in this offering and that hold those common shares as capital assets (generally, property held for investment.) This summary is for general information purposes only and does not purport to be a complete analysis or listing of all potential U.S. federal income tax considerations that may apply to a U.S. Holder as a result of the acquisition of common shares pursuant to this offering. In addition, this summary does not take into account the individual facts and circumstances of any particular U.S. Holder that may affect the U.S. federal income tax consequences to such U.S. Holder, including specific tax consequences to a U.S. Holder under an applicable tax treaty. Accordingly, this summary is not intended to be, and should not be construed as, legal or U.S. federal income tax advice with respect to any particular U.S. Holder. This summary does not address the U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences to U.S. Holders of the acquisition, ownership, and disposition of the securities. Except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each U.S. Holder should consult its own tax advisor regarding the U.S. federal, U.S. federal net investment income, U.S. federal alternative minimum, U.S. federal estate and gift, U.S. state and local, and non-U.S. tax consequences relating to the acquisition, ownership and disposition of the common shares. In addition, this discussion does not discuss tax consequences applicable to U.S. Holders subject to special rules, such as:

• banks, insurance companies, and certain other financial institutions;

• U.S. expatriates and certain former citizens or long-term residents of the United States;

• dealers or traders in securities who use a mark-to-market method of tax accounting;

• persons holding common shares as part of a hedging transaction, “straddle,” wash sale, conversion transaction or integrated transaction or persons entering into a constructive sale with respect to common shares;

• persons whose “functional currency” for U.S. federal income tax purposes is not the U.S. dollar;

• brokers, dealers or traders in securities, commodities or currencies;

• tax-exempt entities or government organizations;

• S corporations, partnerships, or other entities or arrangements classified as partnerships for U.S. federal income tax purposes;

• regulated investment companies or real estate investment trusts;

• persons who acquired our common shares pursuant to the exercise of any employee stock option or otherwise as compensation;

S-49

Table of Contents

• persons holding our common shares in connection with a trade or business, permanent establishment, or fixed base outside the United States; and

• persons who own (directly or through attribution) 10% or more (by vote or value) of our outstanding common shares.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds common shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding common shares and partners in such partnerships are encouraged to consult their tax advisers as to the particular U.S. federal income tax consequences of holding and disposing of common shares.

A “U.S. Holder” is a holder who, for U.S. federal income tax purposes, is a beneficial owner of common shares and is:

• an individual who is a citizen or resident of United States;

• a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia;

• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust if (1) a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or (2) the trust has a valid election in effect to be treated as a U.S. person under applicable U.S. Treasury Regulations.

PERSONS CONSIDERING AN INVESTMENT IN COMMON SHARES SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES APPLICABLE TO THEM RELATING TO THE OWNERSHIP AND DISPOSITION OF THE COMMON SHARES, INCLUDING THE APPLICABILITY OF U.S. FEDERAL, STATE AND LOCAL TAX LAWS.

Passive Foreign Investment Company Rules

If we are considered a “passive foreign investment company” within the meaning of Section 1297 of the Code (a “PFIC”) at any time during a U.S. Holder’s holding period, the following sections will generally describe the potentially adverse U.S. federal income tax consequences to U.S. Holders of the acquisition, ownership, and disposition of the common shares.

In any year in which we are classified as a PFIC, a U.S. Holder will be required to file an annual report with the IRS containing such information as Treasury Regulations and/or other IRS guidance may require. In addition to penalties, a failure to satisfy such reporting requirements may result in an extension of the time period during which the IRS can assess a tax. U.S. Holders should consult their own tax advisors regarding the requirements of filing such information returns under these rules, including the requirement to file an IRS Form 8621.

We generally will be a PFIC for any tax year in which (a) 75% or more of our gross income for such tax year is passive income (the “PFIC income test”) or (b) 50% or more of the value of our assets either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets (the “PFIC asset test”). “Gross income” generally includes sales revenues less the cost of goods sold, plus income from investments and from incidental or outside operations or sources, and “passive income” generally includes, for example, dividends, interest, certain rents and royalties, certain gains from the sale of stock and securities, and certain gains from commodities transactions. Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all of a foreign corporation’s commodities are stock in trade or inventory, depreciable property used in a trade or business or supplies regularly used or consumed in the ordinary course of its trade or business, and certain other requirements are satisfied.

S-50

Table of Contents

For purposes of the PFIC income test and PFIC asset test described above, if we own, directly or indirectly, 25% or more of the total value of the outstanding shares of another corporation, we will be treated as if we (a) held a proportionate share of the assets of such other corporation and (b) received directly a proportionate share of the income of such other corporation. In addition, for purposes of the PFIC income test and PFIC asset test described above, “passive income” does not include any interest, dividends, rents, or royalties that are received or accrued by us from a “related person” (as defined in Section 954(d)(3) of the Code), to the extent such items are properly allocable to the income of such related person that is not passive income.

Under certain attribution rules, if we are a PFIC, U.S. Holders will be deemed to own their proportionate share of any of our subsidiaries which is also a PFIC (a “Subsidiary PFIC”), and will generally be subject to U.S. federal income tax under the “Default PFIC Rules Under Section 1291 of the Code” discussed below on their proportionate share of any (i) distribution on the shares of a Subsidiary PFIC and (ii) disposition or deemed disposition of shares of a Subsidiary PFIC, both as if such U.S. Holders directly held the shares of such Subsidiary PFIC. Accordingly, U.S. Holders should be aware that they could be subject to tax under the PFIC rules even if no distributions are received and no redemptions or other dispositions of the securities are made. In addition, U.S. Holders may be subject to U.S. federal income tax on any indirect gain realized on the stock of a Subsidiary PFIC on the sale or disposition of the securities.

In particular, and without limiting the foregoing, while the Company believes that it was likely a PFIC for the taxable year ending December 31, 2024, no definitive analysis has been undertaken as to whether the Company was a PFIC for the taxable year ending December 31, 2024, or whether it will be for the current or for future taxable years. A separate determination must be made after the close of each taxable year as to whether we are a PFIC for that year, and as a result, our PFIC status may change from year to year. The total value of our assets for purposes of the asset test generally will be calculated using the market price of the common shares, which may fluctuate considerably. Fluctuations in the market price of the common shares may result in us being a PFIC for any taxable year. Because of the uncertainties involved in establishing our PFIC status, there can be no assurance regarding whether we currently are treated as a PFIC, or may be treated as a PFIC in the future. If we are classified as a PFIC in any year during which a U.S. Holder holds the common shares, we generally will continue to be treated as a PFIC as to such U.S. Holder in all succeeding years, regardless of whether we continue to meet the PFIC income test or PFIC asset test discussed above.

Default PFIC Rules Under Section 1291 of the Code

If we are a PFIC, the U.S. federal income tax consequences to a U.S. Holder of the acquisition, ownership, and disposition of the common shares will depend on whether such U.S. Holder makes a “qualified electing fund” or “QEF” election (a “QEF Election”) or makes a mark-to-market election under Section 1296 of the Code (a “Mark-to-Market Election”) with respect to the common shares. A U.S. Holder that does not make either a QEF Election or a Mark-to-Market Election (a “Non-Electing U.S. Holder”) will be taxable as described below.

A Non-Electing U.S. Holder will be subject to the rules of Section 1291 of the Code with respect to (a) any gain recognized on the sale or other taxable disposition of the securities and (b) any excess distribution received on the securities. A distribution generally will be an “excess distribution” to the extent that such distribution (together with all other distributions received in the current tax year) exceeds 125% of the average distributions received during the three preceding tax years (or during a U.S. Holder’s holding period for the common shares, if shorter).

Under Section 1291 of the Code, any gain recognized on the sale or other taxable disposition of the securities of a PFIC (including an indirect disposition of shares of a Subsidiary PFIC), and any excess distribution received on such securities (or a distribution by a Subsidiary PFIC to its shareholder that is deemed to be received by a U.S. Holder) must be ratably allocated to each day in a Non-Electing U.S. Holder’s holding period for the securities. The amount of any such gain or excess distribution allocated to the tax year of disposition or distribution of the excess distribution and to years before the entity became a PFIC, if any, would be taxed as ordinary income (and

S-51

Table of Contents

not eligible for certain preferential tax rates, as discussed below). The amounts allocated to any other tax year would be subject to U.S. federal income tax at the highest tax rate applicable to ordinary income in each such year, and an interest charge would be imposed on the tax liability for each such year, calculated as if such tax liability had been due in each such year. A Non-Electing U.S. Holder that is not a corporation must treat any such interest paid as “personal interest,” which is not deductible.

If we are a PFIC for any tax year during which a Non-Electing U.S. Holder holds the common shares, it will continue to be treated as a PFIC with respect to such Non-Electing U.S. Holder, regardless of whether it ceases to be a PFIC in one or more subsequent tax years. If we cease to be a PFIC, a Non-Electing U.S. Holder may terminate this deemed PFIC status with respect to the common shares by electing to recognize gain (which will be taxed under the rules of Section 1291 of the Code as discussed above) as if such securities were sold on the last day of the last tax year for which we were a PFIC.

QEF Election

A U.S. Holder that makes a QEF Election for the first tax year in which its holding period of its common shares begins generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to its common shares. However, a U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such U.S. Holder’s pro rata share of (a) our net capital gain, which will be taxed as long-term capital gain to such U.S. Holder, and (b) our ordinary earnings, which will be taxed as ordinary income to such U.S. Holder. Generally, “net capital gain” is the excess of (a) net long-term capital gain over (b) net short-term capital loss, and “ordinary earnings” are the excess of (a) “earnings and profits” over (b) net capital gain. A U.S. Holder that makes a QEF Election will be subject to U.S. federal income tax on such amounts for each tax year in which we are a PFIC, regardless of whether such amounts are actually distributed to such U.S. Holder by us. However, for any tax year in which we are a PFIC and have no net income or gain, U.S. Holders that have made a QEF Election would not have any income inclusions as a result of the QEF Election. If a U.S. Holder that made a QEF Election has an income inclusion, such a U.S. Holder may, subject to certain limitations, elect to defer payment of current U.S. federal income tax on such amounts, subject to an interest charge. If such U.S. Holder is not a corporation, any such interest paid will be treated as “personal interest,” which is not deductible.

A U.S. Holder that makes a timely QEF Election generally (a) may receive a tax-free distribution from us to the extent that such distribution represents “earnings and profits” that were previously included in income by the U.S. Holder because of such QEF Election and (b) will adjust such U.S. Holder’s tax basis in the common shares to reflect the amount included in income or allowed as a tax-free distribution because of such QEF Election. In addition, a U.S. Holder that makes a QEF Election generally will recognize capital gain or loss on the sale or other taxable disposition of the common shares.

The procedure for making a QEF Election, and the U.S. federal income tax consequences of making a QEF Election, will depend on whether such QEF Election is timely. A QEF Election will be treated as “timely” for purposes of avoiding the default PFIC rules discussed above if such QEF Election is made for the first year in the U.S. Holder’s holding period for the common shares in which we were a PFIC. A U.S. Holder may make a timely QEF Election by filing the appropriate QEF Election documents at the time such U.S. Holder files a U.S. federal income tax return for such year.

A QEF Election will apply to the tax year for which such QEF Election is made and to all subsequent tax years, unless such QEF Election is invalidated or terminated or the IRS consents to revocation of such QEF Election. If a U.S. Holder makes a QEF Election and, in a subsequent tax year, we cease to be a PFIC, the QEF Election will remain in effect (although it will not be applicable) during those tax years in which we are not a PFIC. Accordingly, if we become a PFIC in another subsequent tax year, the QEF Election will be effective, and the U.S. Holder will be subject to the QEF rules described above during any subsequent tax year in which we qualify as a PFIC.

Table of Contents

A U.S. Holder makes a QEF Election by attaching a completed IRS Form 8621, including a PFIC Annual Information Statement, to a timely filed U.S. federal income tax return. However, if we do not provide the required information with regard to us or any of our Subsidiary PFICs, U.S. Holders will not be able to make a QEF Election for such entity and will continue to be subject to the rules of Section 1291 of the Code discussed above that apply to Non-Electing U.S. Holders with respect to the taxation of gains and excess distributions.

Mark-to-Market Election

A U.S. Holder may make a Mark-to-Market Election with respect to the common shares only if such shares are marketable stock. The common shares generally will be “marketable stock” if the common shares are regularly traded on (a) a national securities exchange that is registered with the SEC, (b) the national market system established pursuant to Section 11A of the Exchange Act or (c) a foreign securities exchange that is regulated or supervised by a governmental authority of the country in which the market is located, provided that (i) such foreign exchange has trading volume, listing, financial disclosure, and other requirements and the laws of the country in which such foreign exchange is located, together with the rules of such foreign exchange, ensure that such requirements are actually enforced and (ii) the rules of such foreign exchange ensure active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be considered “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Provided that the common shares are “regularly traded” as described in the preceding sentence, such shares are expected to be marketable stock. There can be no assurance that the common shares will be “regularly traded” in subsequent calendar quarters. U.S. Holders should consult their own tax advisors regarding the marketable stock rules.

A U.S. Holder that makes a Mark-to-Market Election with respect to its common shares generally will not be subject to the rules of Section 1291 of the Code discussed above with respect to such common shares. However, if a U.S. Holder does not make a Mark-to-Market Election beginning in the first tax year of such U.S. Holder’s holding period for the common shares and such U.S. Holder has not made a timely QEF Election, the rules of Section 1291 of the Code discussed above will apply to certain dispositions of, and distributions on, the common shares.

A U.S. Holder that makes a Mark-to-Market Election will include in ordinary income, for each tax year in which we are a PFIC, an amount equal to the excess, if any, of (a) the fair market value of the common shares as of the close of such tax year over (b) such U.S. Holder’s tax basis in such securities. A U.S. Holder that makes a Mark-to-Market Election will be allowed a deduction in an amount equal to the excess, if any, of (i) such U.S. Holder’s adjusted tax basis in the common shares, over (ii) the fair market value of such securities (but only to the extent of the net amount of previously included income as a result of the Mark-to-Market Election for prior tax years).

A U.S. Holder that makes a Mark-to-Market Election generally also will adjust such U.S. Holder’s tax basis in the common shares to reflect the amount included in gross income or allowed as a deduction because of such Mark-to-Market Election. In addition, upon a sale or other taxable disposition of such securities, a U.S. Holder that makes a Mark-to-Market Election will recognize ordinary income or ordinary loss (not to exceed the excess, if any, of (a) the amount included in ordinary income because of such Mark-to-Market Election for prior tax years over (b) the amount allowed as a deduction because of such Mark-to-Market Election for prior tax years).

A U.S. Holder makes a Mark-to-Market Election by attaching a completed IRS Form 8621 to a timely filed U.S. federal income tax return. A timely Mark-to-Market Election applies to the tax year in which such Mark-to-Market Election is made and to each subsequent tax year, unless the securities cease to be “marketable stock” or the IRS consents to revocation of such election. Each U.S. Holder should consult its own tax advisor regarding the availability of, and procedure for making, a Mark-to-Market Election.

Although a U.S. Holder may be eligible to make a Mark-to-Market Election with respect to the common shares, no such election may be made with respect to the stock of any Subsidiary PFIC that a U.S. Holder is treated as

S-53

Table of Contents

owning because such stock is not marketable. Hence, the Mark-to-Market Election will not be effective to eliminate the interest charge and other income inclusion rules described above with respect to deemed dispositions of Subsidiary PFIC stock or distributions from a Subsidiary PFIC to its shareholder.

Other PFIC Rules

Under Section 1291(f) of the Code, the IRS has issued proposed Treasury Regulations that, subject to certain exceptions, would cause a U.S. Holder that had not made a timely QEF Election to recognize gain (but not loss) upon certain transfers of securities that would otherwise be tax-deferred (e.g., gifts and exchanges pursuant to corporate reorganizations). However, the specific U.S. federal income tax consequences to a U.S. Holder may vary based on the manner in which the securities are transferred.

If finalized in their current form, the proposed Treasury Regulations applicable to PFICs would be effective for transactions occurring on or after April 1, 1992. Because the proposed Treasury Regulations have not yet been adopted in final form, they are not currently effective, and there is no assurance that they will be adopted in the form and with the effective date proposed. Nevertheless, the IRS has announced that, in the absence of final Treasury Regulations, taxpayers may apply reasonable interpretations of the Code provisions applicable to PFICs and that it considers the rules set forth in the proposed Treasury Regulations to be reasonable interpretations of those Code provisions. The PFIC rules are complex, and the implementation of certain aspects of the PFIC rules requires the issuance of Treasury Regulations which in many instances have not been promulgated and which, when promulgated, may have retroactive effect. U.S. Holders should consult their own tax advisors about the potential applicability of the proposed Treasury Regulations.

Certain additional adverse rules will apply with respect to a U.S. Holder if we are a PFIC, regardless of whether such U.S. Holder makes a QEF Election. For example, under Section 1298(b)(6) of the Code, a U.S. Holder that uses the common shares as security for a loan will, except as may be provided in Treasury Regulations, be treated as having made a taxable disposition of such securities.

In addition, a U.S. Holder who acquires common shares from a decedent will not receive a “step up” in tax basis of such securities to fair market value.

Special rules also apply to the amount of foreign tax credit that a U.S. Holder may claim on a distribution from a PFIC. Subject to such special rules, foreign taxes paid with respect to any distribution in respect of stock in a PFIC are generally eligible for the foreign tax credit. The rules relating to distributions by a PFIC and their eligibility for the foreign tax credit are complicated, and a U.S. Holder should consult with their own tax advisor regarding the availability of the foreign tax credit with respect to distributions by a PFIC.

THE PFIC RULES ARE COMPLEX, AND EACH U.S. HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PFIC RULES (INCLUDING THE APPLICABILITY AND ADVISABILITY OF A QEF ELECTION AND MARK-TO-MARKET ELECTION) AND HOW THE PFIC RULES MAY AFFECT THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF THE COMMON SHARES.

Cash Dividends and Other Distributions

Subject to the discussion under “Passive Foreign Investment Company Rules” above, to the extent there are any distributions made with respect to the common shares, a U.S. Holder generally will be required to include in its gross income distributions received with respect to its common shares (including the amount of Canadian taxes withheld, if any) as dividend income, but only to the extent that the distribution is paid out of our current or accumulated earnings and profits (computed using U.S. federal income tax principles), with the excess treated first as a non-taxable return of capital to the extent of the holder’s adjusted tax basis in its common shares and, thereafter, as capital gain recognized on a sale or exchange on the day actually or constructively received by the

S-54

Table of Contents

holder (as described below under “Sale or Disposition of Common Shares”). There can be no assurance that we will maintain calculations of our earnings and profits in accordance with U.S. federal income tax accounting principles. U.S. Holders should therefore assume that any distribution with respect to the common shares will constitute ordinary dividend income. Dividends paid on the common shares will not be eligible for the dividends received deduction allowed to U.S. corporations.

Dividends paid to a non-corporate U.S. Holder by a “qualified foreign corporation” may be subject to reduced rates of taxation if certain holding period and other requirements are met. A qualified foreign corporation generally includes a foreign corporation if (i) its common shares are readily tradable on an established securities market in the United States or it is eligible for benefits under a comprehensive U.S. income tax treaty that includes an exchange of information program and which the U.S. Treasury has determined is satisfactory for these purposes and (ii) if such foreign corporation is not a PFIC (as discussed above) for either the taxable year in which the dividend is paid or the preceding taxable year. The Company believes that it qualifies as a resident of Canada for purposes of, and are eligible for the benefits of, the Canada-United States Income Tax Convention (1980) as amended, which the IRS has determined is satisfactory for purposes of the qualified dividend rules and that it includes an exchange of information provision, although there can be no assurance in this regard. In addition, the common shares are expected to be readily tradable on an established securities market, the TSX and Nasdaq. However, whether our common shares are regularly traded on a qualified exchange is an annual determination based on facts that, in part, are beyond our control. In addition, we may be eligible for the benefits of the Treaty. Accordingly, subject to the PFIC rules discussed above, we expect that a non-corporate U.S. Holder should qualify for the reduced rate on dividends so long as the applicable holding period requirements are met. U.S. Holders should consult their own tax advisors regarding the availability of the reduced tax rate on dividends in light of their particular circumstances.

The amount of any distribution paid to a U.S. Holder in foreign currency or on the sale, exchange or other taxable disposition of the common shares generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is converted into U.S. dollars at that time). If the foreign currency received is not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a tax basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who receives payment in foreign currency and engages in a subsequent conversion or other disposition of the foreign currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally will be U.S. source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders who use the accrual method of tax accounting. Each U.S. Holder should consult its own U.S. tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Subject to the PFIC rules discussed above, a U.S. Holder that pays (whether directly or through withholding) Canadian income tax with respect to dividends paid on the common shares generally will be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such Canadian income tax paid. Generally, a credit will reduce a U.S. Holder’s U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder’s income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid or accrued (whether directly or through withholding) by a U.S. Holder during a year. The foreign tax credit rules are complex and involve the application of rules that depend on a U.S. Holder’s particular circumstances. Accordingly, each U.S. Holder should consult its own tax advisor regarding the foreign tax credit rules.

Sale or Disposition of Common Shares

A U.S. Holder generally will recognize gain or loss on the taxable sale or exchange of the common shares in an amount equal to the difference between the U.S. dollar amount realized on such sale or exchange (determined in the case of the common shares sold or exchanged for currencies other than U.S. dollars by reference to the spot exchange rate in effect on the date of the sale or exchange or, if the common shares sold or exchanged are traded

S-55

Table of Contents

on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, which election must be applied consistently from year to year and cannot be changed without the consent of the IRS, the spot exchange rate in effect on the settlement date) and the U.S. Holder’s adjusted tax basis in the common shares determined in U.S. dollars. The initial tax basis of the common shares to a U.S. Holder will be the U.S. Holder’s U.S. dollar purchase price for the common shares (determined by reference to the spot exchange rate in effect on the date of the purchase, or if the common shares purchased are traded on an established securities market and the U.S. Holder is a cash basis taxpayer or an electing accrual basis taxpayer, which election must be applied consistently from year to year and cannot be changed without the consent of the IRS, the spot exchange rate in effect on the settlement date). An accrual basis U.S. Holder that does not make the special election will recognize exchange gain or loss to the extent attributable to the difference between the exchange rates on the sale date and the settlement date, and such exchange gain or loss generally will constitute ordinary income or loss.

Subject to the discussion under “Passive Foreign Investment Company Rules” above, such gain or loss will be capital gain or loss and will be long-term gain or loss if the common shares have been held for more than one year. Under current law, long-term capital gains of non-corporate U.S. Holders generally are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations. Capital gain or loss, if any, recognized by a U.S. Holder generally will be treated as U.S. source income or loss for U.S. foreign tax credit purposes. U.S. Holders are encouraged to consult their own tax advisors regarding the availability of the U.S. foreign tax credit in their particular circumstances.

Information Reporting and Backup Withholding

Under U.S. federal income tax laws certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement in, a foreign corporation. For example, U.S. return disclosure obligations (and related penalties) are imposed on U.S. Holders that hold certain specified foreign financial assets in excess of certain threshold amounts. The definition of specified foreign financial assets includes not only financial accounts maintained in foreign financial institutions, but also, unless held in accounts maintained by a financial institution, any stock or security issued by a non-U.S. person. U. S. Holders may be subject to these reporting requirements unless the securities are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders paying more than US$100,000 for our common shares generally may be required to file IRS Form 926 reporting the payment of the offer price for our common shares to us. Substantial penalties may be imposed upon a U.S. Holder that fails to comply. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns, including the requirement to file IRS Forms 926 and 8938.

Payments made within the U.S., or by a U.S. payor or U.S. middleman, of dividends on, and proceeds arising from the sale or other taxable disposition of the securities generally may be subject to information reporting and backup withholding tax, currently at the rate of 24%, if a U.S. Holder (a) fails to furnish its correct U.S. taxpayer identification number (generally on Form W-9), (b) furnishes an incorrect U.S. taxpayer identification number, (c) is notified by the IRS that such U.S. Holder has previously failed to properly report items subject to backup withholding tax, or (d) fails to certify, under penalty of perjury, that it has furnished its correct U.S. taxpayer identification number and that the IRS has not notified such U.S. Holder that it is subject to backup withholding tax. However, certain exempt persons, such as U.S. Holders that are corporations, generally are excluded from these information reporting and backup withholding tax rules. Any amounts withheld under the U.S. backup withholding tax rules will be allowed as a credit against a U.S. Holder’s U.S. federal income tax liability, if any, or will be refunded, if such U.S. Holder furnishes required information to the IRS in a timely manner.

The discussion of reporting requirements set forth above is not intended to constitute a complete description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax and, under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting

requirement. Each U.S. Holder should consult its own tax advisors regarding the information reporting and backup withholding rules.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO U.S. HOLDERS WITH RESPECT TO THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF THE COMMON SHARES. U.S. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR OWN PARTICULAR CIRCUMSTANCES.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a company incorporated under the Business Corporations Act (British Columbia). Most of our directors and officers are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets may be, and a substantial portion of our assets are, located outside the United States. We have appointed an agent for service of process in the United States, but it may be difficult for holders of securities who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States. It may also be difficult for holders of securities who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors, officers and experts under the United States federal securities laws. We have been advised that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws or the securities or “blue sky” laws of any state within the United States, would likely be enforceable in Canada if the U.S. court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. We have also been advised, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of the liability predicated solely upon U.S. federal securities laws.

We filed with the SEC, concurrently with our registration statement on Form F-10 of which this prospectus supplement is a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, we have appointed Corporation Service Company as our agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving us in a U.S. court arising out of or related to or concerning the offering of securities under this prospectus supplement.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE U.S. SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION OR ANY U.S. REGULATORY AUTHORITY NOR HAVE THESE AUTHORITIES PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

This prospectus constitutes a public offering of the Securities only in those jurisdictions where they may be lawfully offered for sale and only by persons permitted to sell the Securities in such jurisdiction. All applicable information permitted under securities legislation to be omitted from this prospectus that has been so omitted will be contained in one or more prospectus supplements that will be delivered to purchasers together with this prospectus, except that delivery is not required where an exemption from the delivery requirements in the legislation is available. Each prospectus supplement will be incorporated by reference into this prospectus for the purposes of securities legislation as of the date of the prospectus supplement and only for the purposes of the distribution of the Securities to which the prospectus supplement pertains. You should read this prospectus and any applicable prospectus supplement carefully before you invest in any Securities issued pursuant to this prospectus. Our Securities may be sold pursuant to this prospectus through underwriters or dealers or directly or through agents designated from time to time at amounts and prices and other terms determined by us.

In connection with any underwritten offering of Securities, other than an “at-the-market distribution” (as defined in National Instrument 44-102 – Shelf Distributions (“NI 44-102”)), unless otherwise specified in the relevant prospectus supplement the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered. Such transactions, if commenced, may be discontinued at any time. A purchaser who acquires Securities forming part of the underwriters’ over-allocation position acquires those Securities under this prospectus, regardless of whether the over-allocation position is ultimately filled through the exercise of the over-allotment option or secondary market purchases. See “Plan of Distribution”.

No underwriter or dealer involved in an “at-the-market distribution” under this prospectus, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such underwriter or dealer will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities.

We or any selling securityholder may offer and sell the Securities issued under this prospectus to or through underwriters, dealers, placement agents or other intermediaries or directly to one or more purchasers, subject in each case to obtaining any required exemptions under applicable securities laws. The distribution of Securities under this prospectus may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed from time to time, at market prices prevailing at the time of sale, or at prices related to such prevailing market prices, or at other negotiated prices, in each case as set forth in the applicable prospectus supplement.

The prospectus supplement relating to a particular offering of Securities will identify each selling securityholder, underwriter, dealer or agent engaged in connection with an offering and sale of Securities pursuant to this prospectus and will set forth the terms of the offering of such Securities, including our proceeds and, to the extent applicable, any fees, discounts, concessions or other compensation payable to the underwriters, dealers or agents, the method of distribution, the initial issue price (in the event that the offering is a fixed price distribution) and any other material terms of the plan of distribution. This prospectus may qualify an “at-the-market distribution”, as defined in NI 44-102. See “Plan of Distribution”.

Investment in the Securities being offered is highly speculative and involves significant risks that you should consider before purchasing such Securities. You should carefully review the risks outlined in this prospectus (including any prospectus supplement) and in the documents incorporated by reference as well as the information under the heading “Cautionary Note Regarding Forward-Looking Statements” and consider such risks and information in connection with an investment in the Securities. See “Risk Factors”.

We have not authorized anyone to provide you with different or additional information. If anyone provides you with different or additional information, you should not rely on it. We are not making an offer to sell or seeking an offer to buy the Securities offered pursuant to this prospectus in any jurisdiction where the offer or sale is not permitted. You should assume that the information contained in this prospectus and any applicable prospectus supplement is accurate only as of the date on the front of such document and that information contained in any document incorporated by reference is accurate only as of the date of that document, regardless of the time of delivery of this prospectus or any applicable prospectus supplement or of any sale of our Securities pursuant thereto. Our business, financial condition, results of operations and prospects may have changed since those dates.

Market data and certain industry forecasts used in this prospectus and any applicable prospectus supplement, and the documents incorporated by reference in this prospectus and any applicable prospectus supplement, were obtained from market research, publicly available information and industry publications. We believe that these sources are generally reliable, but the accuracy and completeness of this information is not guaranteed. We have not independently verified such information, and we do not make any representation as to the accuracy of such information.

All regulatory filings to-date and communication from the Company have been made referencing EP-104IAR. In the interest of greater clarity for investors, the Company will use EP-104IAR when referring to the product candidate that is intended for intra-articular injections for indications such as osteoarthritis (“OA”), EP-104GI when referring to the product candidate that is intended for submucosal injections in the gastrointestinal (“GI”) tract for indications such as eosinophilic esophagitis (“EoE”), and simply refer to the product candidate as EP-104 in conjunction with topics that are related to both EP-104IAR and EP-104GI.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The Company cautions readers regarding forward-looking statements found in this prospectus (including the documents incorporated by reference herein). This prospectus, including the documents incorporated by reference herein, contains “forward-looking statements” within the meaning of U.S. securities laws and “forward-looking information” within the meaning of Canadian securities laws (collectively, “forward-looking information”). Such forward-looking information includes, but is not limited to, information with respect to our objectives and the strategies to achieve these objectives, as well as information with respect to our beliefs, plans, expectations, anticipations, estimates and intentions. This forward-looking information is identified by the use of terms and phrases such as may,” “might,” “will,” “likely”, “could,” “would,” “should,” “expect,” “intend,” “plan,” “objective,” “goal,” “outlook,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “forecast,” “estimate,” “potential,” “target,” “seek,” “contemplate,” “continue,” “design,” and “ongoing,” the negative of these terms and similar terminology, including references to assumptions, although not all forward-looking information contains these terms and phrases. In addition, any statements in this prospectus or in the documents incorporated by reference herein that refer to expectations, intentions, projections or other characterizations of future events or circumstances, contain forward-looking information.

Forward-looking information involves known and unknown risks and uncertainties, many of which are beyond our control, that could cause actual results to differ materially from those that are disclosed in or implied by such forward-looking information. These risks and uncertainties include, but are not limited to, those described in greater detail under “Risk Factors” below and in the Annual Information Form, including:

• we have a limited operating history and have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability;

• we will require substantial additional financing to achieve our goals and a failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development or commercialization efforts;

• we are substantially dependent on the success of our lead product candidate EP-104IAR, which is currently in clinical trials and EP-104GI, and if we are unable to complete development of, obtain approval for and commercialize EP-104IAR and EP-104GI in a timely manner, our business will be harmed;

• if we breach any of the agreements under which we license rights to our product candidates or technology from third parties, we could lose license rights that are important to our business. Our current license agreement may not provide an adequate remedy for its breach by the licensor;

• adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect the Company’s current and projected business operations and its financial condition and results of operations;

• clinical trials are expensive, time consuming and difficult to design and implement and may fail to demonstrate adequate safety and efficacy of our product candidates;

• the results of previous preclinical studies and clinical trials may not be predictive of future results, and the results of our current and planned clinical trials may not satisfy the requirements of the U.S. Food and Drug Administration (the “FDA”) or comparable non-U.S. regulatory authorities or provide the basis for regulatory approval;

• our lead product candidate may not be successful for its intended use;

• our current and future product candidates will require regulatory approval, which is costly, and we may not be able to obtain it and we may fail to obtain regulatory approvals or only obtain approvals for limited uses or indications;

8

Table of Contents

• the clinical trials of our product candidates may not demonstrate safety and efficacy to the satisfaction of the FDA, European Medicine Agency (“EMA”) or other comparable foreign regulatory authorities or otherwise produce positive results;

• we completely rely on third parties to provide supplies and inputs required for our products;

• we rely on external contract research organizations (“CROs”) to provide clinical and non-clinical research services; if such CROs do not successfully carry out their contractual duties including to comply with applicable laws and regulations or meet expected deadlines, our business could be substantially harmed;

• the manufacture of drugs is complex and our third-party manufacturers may encounter difficulties in production. If any of our third-party manufacturers encounter such difficulties, our ability to provide adequate supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or prevented;

• the outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA, EMA or other comparable foreign regulatory authorities. Terminating the development of any of our product candidates could materially harm our business and the market price of our common shares;

• interim, initial, “top-line”, and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data;

• any safety concerns observed in any one of our clinical trials in our targeted indications could limit the prospects for regulatory approval of our product candidates in those and other indications, which could seriously harm our business;

• our current or future product candidates may cause significant adverse events, toxicities or other undesirable side effects when used alone or in combination with other products that may result in a safety profile that could inhibit regulatory approval, prevent market acceptance, limit their commercial potential or result in significant negative consequences;

• where appropriate and applicable, we may seek approval from the FDA or comparable foreign regulatory authorities through the use of expedited approval pathways, such as Fast Track designation or orphan drug designation; even if we receive Fast Track designation or other designation, we can provide no assurance that we will be able to obtain FDA approval sooner or if at all;

• if we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our drug candidates, if approved, we may be unable to generate any product revenue;

• we have a novel technology with uncertain market acceptance, if approved;

• if we experience delays or difficulties in the enrollment and/or maintenance of patients in clinical trials, our clinical development activities could be delayed or otherwise adversely affected;

• the FDA, EMA and other comparable foreign regulatory authorities may not accept data from trials conducted in locations outside of their jurisdiction;

• obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions;

• if the market opportunity for any product candidate that we or our strategic partners develop is smaller than we believe, our revenue may be adversely affected and our business may suffer;

• even if our product candidates receive regulatory approval, they will be subject to significant post marketing regulatory requirements and oversight;

9

Table of Contents

• the FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off label uses;

• disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business;

• we rely on key personnel;

• we may not be able to successfully execute our business strategy;

• we are in a highly competitive industry which is continuously evolving with technological changes;

• our future success will depend on our ability to continually enhance and develop our product candidates;

• we may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success;

• changes in methods of product candidate manufacturing or formulation may result in additional costs or delay;

• if we are unable to differentiate EP-104IAR from existing therapies for treatment of OA, or if the FDA or other applicable regulatory authorities approve generic products that compete with EP-104IAR, our ability to successfully commercialize EP-104IAR would be adversely affected;

• a variety of risks associated with potential international business relationships could materially adversely affect our business;

• collaboration arrangements we may enter into in the future may not be successful;

• we may acquire businesses or products, or form strategic alliances in the future, and we may not realize the benefits of such acquisitions or alliances;

• we have traditionally relied on key collaborations and grants;

• our business and operations could suffer in the event of an actual or perceived information security incident such as a cybersecurity breach, system failure, or other compromise of our systems or those of a third-party or other contractor or vendor;

• we may fail to manage our growth successfully, which may adversely impact our operating results;

• we rely on the protection of our intellectual property rights;

• we may not be able to enforce our intellectual property rights throughout the world;

EUPRAXIA PHARMACEUTICALS INC.

Business of the Company

Eupraxia is a clinical stage biotechnology company focused on the development of locally delivered, extended-release alternatives to existing pharmaceuticals to create novel products that are “first-time” uses for the molecule or drug class, or “best-in-class” products for indications where efficacy has already been established. Leveraging our proprietary and innovative Diffusphere^TM delivery technology, Eupraxia’s goal is to provide the right dose of drug, in the right place, for the right amount of time in indications with a high unmet medical need. Each of Eupraxia’s product candidates are designed to achieve improved patient benefit by providing more prolonged activity than currently available treatments, combined with an improved pharmacokinetics (“PK”) and related safety profile and combined with precisely targeted local delivery. We believe products with this profile offer the dual potential of providing long-lasting treatment while minimizing tolerability complications in target and non-target tissues. The Company’s strategy is to develop a portfolio of product candidates based on this delivery technology.

Eupraxia currently has two distinct clinical development programs, one targeting chronic osteoarthritis (“OA”) pain in the knee and the second targeting GI indications, with an initial focus on Eosinophilic Esophagitis (“EoE”). Currently, both programs are based upon injectable fluticasone microspheres that use Eupraxia’s Diffusphere^TM Technology. The injectable drug is dispensed together with a “vehicle” specifically designed for the target and co-administered with the active pharmaceutical ingredient (“API”). For our ongoing clinical studies we are using the same underlying API, differentiated by vehicle and delivery methods. In the future, we anticipate that products intended for different therapeutic indications and modes of administration (for example, IAR and submucosal) will be differentiated by dosing levels, vehicle and delivery methods and will be distinct product candidates. The product candidate that is being developed specifically for IAR injections with an initial indication of knee OA is referred to as EP-104IAR, whereas the product candidate that will be developed for submucosal injections in the GI tract with an initial indication of EoE is referred to as EP-104GI.

RISK FACTORS

Before making an investment decision, prospective purchasers of Securities should carefully consider the information described in this prospectus, any applicable prospectus supplement and the documents incorporated by reference herein and therein. Additional risk factors relating to a specific offering of Securities may be described in the applicable prospectus supplement. Some of the risk factors described herein, in any applicable prospectus supplement and in the documents incorporated by reference herein and therein, are interrelated and, consequently, investors should treat such risk factors as a whole. If any event arising from these risks occurs, our business, prospects, financial condition, results of operations and cash flows, and your investment in the Securities could be materially adversely affected. Additional risks and uncertainties of which we currently are unaware or that are unknown or that we currently deem to be immaterial could have a material adverse effect on our business, financial condition and results of operation. Our Risk Factors are not guarantees that no such conditions exist as of the date of this report and should not be interpreted as an affirmative statement that such risks or conditions have not materialized, in whole or in part. We cannot assure you that we will successfully address any or all of these risks. For additional information in respect of the risks affecting our business, see the section “Risk Factors” of our Annual Information Form, which is incorporated herein by reference and available under our profile on SEDAR+ at www.sedarplus.ca.

Risks Relating to New Securities

Investing in the Securities is speculative, and investors could lose their entire investment.

An investment in the Securities is speculative and may result in the loss of an investor’s entire investment. Only potential investors who are experienced in high-risk investments and who can afford to lose their entire investment should consider an investment in the Securities.

Any issuance of preferred shares could make it difficult for another company to acquire us or could otherwise adversely affect holders of our Common Shares, which could depress the price of our Common Shares.

Our board of directors (the “Board”) has the authority to issue preferred shares and to determine the preferences, limitations and relative rights of preferred shares and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by our shareholders. Our preferred shares may be issued with liquidation, dividend and other rights superior to the rights of our Common Shares. The potential issuance of preferred shares may delay or prevent a change in control of the Company, discourage bids for our Common Shares at a premium over the market price and adversely affect the market price and other rights of the holders of our Common Shares.

Our constating documents permit us to issue an unlimited number of Common Shares without additional shareholder approval.

Our notice of articles and articles (the “Articles”) permit us to issue an unlimited number of Common Shares. We anticipate that we will, from time to time, issue additional Common Shares in the future. Subject to the requirements of the TSX and, if applicable, the Nasdaq Capital Market, we will not be required to obtain the approval of shareholders for the issuance of additional Common Shares. Any further issuances of Common Shares will result in immediate dilution to existing shareholders and may have an adverse effect on the value of their shareholdings.

We have a history of negative operating cash flow and may continue to experience negative operating cash flow.

Since its incorporation in May 2011, the Company has generated negative operating cash flows. The Company anticipates that it will continue to have negative cash flow and it expects to continue to incur losses for the

18

Table of Contents

foreseeable future as the Company continues to research and develop, and seek regulatory clearances for, its current product candidate and other potential product candidates. To the extent that the Company has negative operating cash flow in future periods, it may need to allocate a portion of its cash reserves to fund such negative cash flow. The Company may also be required to raise additional funds through the issuance of equity or debt securities. There can be no assurance that the Company will be able to generate a positive cash flow from its operations, that additional capital or other types of financing will be available when needed or that these financings will be on terms favourable to the Company.

Issuance of securities of the Company could cause dilution.

The Company may sell additional equity securities (including through the sale of Securities convertible into Common Shares) and may issue additional debt or equity securities to finance its research & development, evaluation, manufacturing, operations, acquisitions, or other projects. The Company is authorized to issue an unlimited number of Common Shares. The Company cannot predict the size of future sales and issuances of debt or equity securities or the effect, if any, that future sales and issuances of debt or equity securities will have on the market price of the Common Shares. Sales or issuances of a substantial number of equity securities, or the perception that such sales could occur, may adversely affect prevailing market prices for the Common Shares. With any additional sale or issuance of equity securities, investors may suffer dilution of their voting power and it could reduce the value of their investment.

The exercise of stock options could cause dilution.

The Company has outstanding stock options representing a right to receive Common Shares upon vesting and the exercise of the stock options. The exercise of stock options, and the subsequent resale of such Common Shares in the public market, could adversely affect the prevailing market price of the Common Shares and the Company’s ability to raise equity capital in the future at a time and price which it deems appropriate. The Company may also enter into commitments in the future which would require the issuance of additional Common Shares and the Company is expected to grant additional stock options. Any Common Shares issuances from the Company’s treasury will result in immediate dilution to existing shareholders’ percentage interest in the Company.

The Company has warrants, convertible debt, and shares of a subsidiary exchangeable for Common Shares outstanding, which in each case, if exercised, converted or exchanged, respectively, could cause dilution to existing shareholders.

The Company has outstanding warrants that are exercisable for Common Shares. In addition, the Company has outstanding convertible debt that are convertible into Common Shares. Furthermore, Eupraxia Pharma Inc., the Company’s subsidiary, has non-voting Class B shares (the “Class B Shares”) outstanding that are exchangeable into Common Shares. The exercise of such warrants, conversion of such convertible debt and exchange of such Class B Shares and the subsequent resale of such Common Shares, issuable thereunder in each case, in the public market could adversely affect the prevailing market price and the Company’s ability to raise equity capital in the future at a time and price which it deems appropriate. The Company may also enter into commitments in the future which would require the issuance of additional Common Shares and the Company may grant additional share purchase warrants or stock options. Any share issuances from the Company’s treasury will result in immediate dilution to existing shareholders’ percentage interest in the Company.

Our Common Shares may have limited liquidity.

Shareholders of the Company may be unable to sell significant quantities of Common Shares into the public trading markets without a significant reduction in the price of their Common Shares, or at all. There can be no assurance that there will be sufficient liquidity of the Common Shares on the trading market, and that the Company will continue to meet the listing requirements of the TSX, achieve and maintain a listing on the Nasdaq Capital Market, or achieve or maintain a listing on any other securities exchange.

19

Table of Contents

There is no established market for certain securities, and the Company does not know whether an active market will develop for Common Shares on the Nasdaq Capital Market if the Common Shares are listed.

There is no public market for the preferred shares, debt securities, warrants, subscription receipts or units contemplated by this prospectus and, unless otherwise specified in the applicable prospectus supplement, the Company does not intend to apply for listing of the preferred shares, debt securities, warrants, subscription receipts or units on any securities exchanges. If the preferred shares, debt securities, warrants, subscription receipts or units are traded after their initial issuance, they may trade at a discount from their initial offering prices depending on prevailing interest rates (as applicable), the market for similar securities and other factors, including general economic conditions and our financial condition. There can be no assurance as to the liquidity of the trading market for the preferred shares, debt securities, warrants, subscription receipts or units, or that a trading market for these securities will develop at all.

Further, the Company has applied to list the Common Shares on the Nasdaq Capital Market, under the symbol “EPRX.” However, there has been no prior public trading market for the Common Shares on the Nasdaq Capital Market. The Company cannot assure you that it will complete its listing of the Common Shares on the Nasdaq Capital Market, if it completes its listing of the Common Shares on the Nasdaq Capital Market that such listing is maintained, or that an active trading market for the Common Shares will develop on the Nasdaq Capital Market or elsewhere or, if developed, that any market will be sustained. Accordingly, the Company cannot assure you of the liquidity of any trading market, your ability to sell the Common Shares when desired or the prices that you may obtain for your shares.

Our debt securities may be unsecured.

Unless otherwise indicated in the applicable prospectus supplement, the debt securities may be unsecured and will rank equally in right of payment with all our other existing and future unsecured debt. Any unsecured debt securities will be effectively subordinated to all our existing and future secured debt to the extent of the assets securing such debt. If we are involved in any bankruptcy, dissolution, liquidation or reorganization, the secured debt holders would, to the extent of the value of the assets securing the secured debt, be paid before the holders of unsecured debt securities, including the debt securities. In that event, a holder of debt securities may not be able to recover any principal or interest due to it under the debt securities. See “Description of Debt Securities”.

Prevailing interest rates may affect the market price or value of any debt securities of the Company.

Prevailing interest rates may affect the market price or value of any debt securities. The market price or value of any debt securities may decline as prevailing interest rates for comparable debt instruments rise and increase as prevailing interest rates for comparable debt instruments decline.

Fluctuations in foreign currency markets may affect the market price or value of any debt securities of the Company.

Debt securities denominated or payable in foreign currencies may entail significant risk. These risks include, without limitation, the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential liquidity restrictions in the secondary market. These risks will vary depending upon the currency or currencies involved and will be more fully described in the applicable prospectus supplement.

United States investors may not be able to obtain enforcement of civil liabilities against us.

The enforcement by investors of civil liabilities under the United States federal or state securities laws may be affected adversely by the fact that we are governed by the Business Corporations Act (British Columbia), that the majority of our officers and directors are residents of Canada or otherwise reside outside the United States, and

20

Table of Contents

that all, or a substantial portion of their assets and a substantial portion of our assets, are located outside the United States. It may not be possible for investors to effect service of process within the United States on certain of our directors and officers or enforce judgments obtained in the United States courts against us or certain of our directors and officers based upon the civil liability provisions of United States federal securities laws or the securities laws of any state of the United States.

There is some doubt as to whether a judgment of a United States court based solely upon the civil liability provisions of United States federal or state securities laws would be enforceable in Canada against us or our directors and officers. There is also doubt as to whether an original action could be brought in Canada against us or our directors and officers to enforce liabilities based solely upon United States federal or state securities laws.

As a foreign private issuer, we are subject to different U.S. securities laws and rules than a domestic U.S. issuer, which may limit the information publicly available to our U.S. shareholders.

We are a foreign private issuer under applicable U.S. federal securities laws and, therefore, we will not be required to comply with all the periodic disclosure and current reporting requirements of the Exchange Act, as amended, and related rules and regulations, should we become subject to such requirements in the future. As a result, we will not file the same reports that a U.S. domestic issuer would file with the SEC, although we will be required to file with or furnish to the SEC the continuous disclosure documents that we are required to file in Canada under Canadian securities laws. In addition, our officers, directors and principal shareholders will be exempt from the reporting and “short swing” profit recovery provisions of Section 16 of the Exchange Act. Therefore, our shareholders may not know on as timely a basis when our officers, directors and principal shareholders purchase or sell Common Shares as the reporting periods under the corresponding Canadian insider reporting requirements are longer. In addition, as a foreign private issuer, we will be exempt from the proxy rules under the Exchange Act.

We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses to us.

In order to maintain our current status as a foreign private issuer, a majority of our Common Shares must be either directly or indirectly owned by non-residents of the United States unless we also satisfy one of the additional requirements necessary to preserve this status. We may in the future lose our foreign private issuer status if a majority of the Common Shares are held in the United States and we fail to meet the additional requirements necessary to avoid loss of foreign private issuer status. The regulatory and compliance costs to us under U.S. federal securities laws as a U.S. domestic issuer may be significantly more than the costs we incur as a Canadian foreign private issuer eligible to use the multijurisdictional disclosure system. If we are not a foreign private issuer, we would not be eligible to use the multijurisdictional disclosure system or other foreign issuer forms and would be required to file periodic and current reports and registration statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign private issuer. In addition, should we become listed on the Nasdaq Capital Market, we may lose the ability to rely upon exemptions from Nasdaq corporate governance requirements that are available to foreign private issuers.

We will have broad discretion over the use of proceeds from sales of the Securities, and we may not use the proceeds in the desired manner.

Management will have discretion concerning the use of the proceeds from sales of the Securities as well as the timing of their expenditure. As a result, an investor will be relying on the judgment of management for the application of the proceeds from sales of the Securities. Management may use the net proceeds from sales of the Securities other than as described under the heading “Use of Proceeds” if they believe it would be in our best interest to do so and in ways that an investor may not consider desirable. The results and the effectiveness of the application of the proceeds are uncertain. If the proceeds are not applied effectively, our results of operations may suffer.

Risks Relating to the Company’s Business

We have a limited operating history and have no products approved for commercial sale, which may make it difficult for you to evaluate our current business and predict our future success and viability.

We are a clinical stage biotechnology company with limited operating history and in particular, no history of earnings; we have not paid any dividends and we are unlikely to pay any dividends in the immediate or foreseeable future. Our success will depend to a large extent on the expertise, ability, judgement, discretion, integrity and good faith of our management.

We have no products approved for commercial sale in any jurisdiction and have not generated any revenue from product sales. To date, we have devoted substantially all of our resources and efforts to organizing and staffing our company, business planning, discovering, identifying and developing potential product candidates, securing related intellectual property rights and conducting preclinical studies and clinical trials of our product candidates. We have not yet demonstrated our ability to obtain marketing approvals, manufacture a commercial-scale product or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful product commercialization. As a result, it may be more difficult for you to accurately predict our future success or viability.

In addition, we may encounter unforeseen expenses, difficulties, complications, delays and other known and unknown factors and risks frequently experienced by clinical stage pharmaceutical companies in rapidly evolving fields. We also may need to transition from a company with a research focus to a company capable of supporting commercial activities. If we do not adequately address these risks and difficulties or successfully make such a transition, our business will suffer.

We expect to spend a significant amount of capital to fund research and development. As a result, we expect that our operating expenses will increase significantly and, consequently, we will need to generate significant revenues to become profitable. Even if we do become profitable, we may not be able to sustain or increase profitability on a quarterly or annual basis. We cannot predict when, if ever, we will be profitable. There can be no assurances that we will be capable of producing our products in commercial quantities at reasonable costs or that we will successfully market them.

We will require substantial additional financing to achieve our goals and a failure to obtain this necessary capital when needed could force us to delay, limit, reduce or terminate our product development or commercialization efforts.

As of September 30, 2023, we had C$33.2 million of cash and cash equivalents. Based upon our current operating plan, we estimate that our cash and cash equivalents as of September 30, 2023 are insufficient for us to fund operating, investing, and financing cash flow needs for twelve months following September 30, 2023, the date of our unaudited condensed interim consolidated financial statements for the most recently completed financial period, and accordingly, we have determined that there is substantial doubt about our ability to continue as a going concern. We believe that we will continue to expend substantial resources for the foreseeable future as we continue the development of EP-104, develop additional product candidates, if any, and launch clinical trials for such product candidates and pursue commercialization of product candidates, if approved. In addition, other unanticipated costs may arise. Because the outcome of our planned and anticipated clinical trials are highly uncertain, we cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of product candidates. Our costs will increase if we suffer any delays in our planned clinical trials for our current product candidates. Our forecast of the period of time through which our financial reserves will adequately support our operations is a forward-looking statement and involves risks and uncertainties, and actual results could vary as a result of a number of factors, including the factors discussed elsewhere in this “Risk Factors” section. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect.

22

Table of Contents

Our future capital requirements will depend on many factors, including:

• the timing of, and the costs involved in, obtaining regulatory approvals for product candidates if clinical trials are successful;

• the scope, progress, results and costs of developing and advancing product candidates through clinical trials and researching and discovering new product candidates;

• our ability to establish and maintain strategic partnerships, licensing or other arrangements and the financial terms of such agreements;

• the cost of manufacturing product candidates for clinical trials in preparation for regulatory approval and in preparation for commercialization;

• the amount of revenue from an approved product candidate, if any; and

• the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome of such litigation.

The ongoing economic slowdown and downturn of global capital markets has generally made the raising of capital by equity or debt financing more difficult. Access to financing has been negatively impacted by ongoing global economic risks. We will require substantial additional funds for further research and development, and the marketing and sale of its technology. We may attempt to raise additional funds for these purposes through public or private equity or debt financing, collaborations with other therapeutic companies, government grants or other sources. There can be no assurance that additional funding or partnerships will be available on terms acceptable to us and which would foster the successful commercialization of our technologies. If additional funds are raised through further issuances of equity or convertible debt securities, existing shareholders could suffer significant dilution, and any new equity securities issued could have rights, preferences and privileges superior to those of the Common Shares. Any debt financing secured in the future could involve restrictive covenants relating to capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital or to pursue business opportunities, including potential acquisitions. If adequate funds are not obtained, we may be required to reduce, curtail or discontinue operations.

We are substantially dependent on the success of our lead product candidate EP-104IAR, which is currently in clinical trials, and EP-104GI. If we are unable to complete development of, obtain approval for and commercialize EP-104IAR and EP-104GI in a timely manner, our business will be harmed.

Our future success is dependent on our ability to timely complete clinical trials, obtain marketing approval for and successfully commercialize EP-104IAR, our lead product candidate, and EP-104GI. We are investing significant efforts and financial resources in the research and development of EP-104IAR and EP-104GI. We have conducted a Phase 2 clinical trial for the proposed indication of OA and are conducting a Phase 1b/2a clinical trial for the proposed indication of EoE. Both indications will require additional clinical development, evaluation of clinical, preclinical and manufacturing activities, marketing approval from government regulators, substantial investment and significant marketing efforts before we can generate any revenues from sales of any approved products. We are not permitted to market or promote EP-104IAR, EP-104GI or any other product candidate, before we receive marketing approval from the FDA and/or comparable foreign regulatory authorities, and we may never receive such marketing approval.

Our ability to generate revenue and achieve profitability depends significantly on several factors, including but not limited to the following:

• successful and timely completion of nonclinical and clinical development of our product candidates and any future product candidates, as well as the associated costs, including any unforeseen costs we may incur as a result of nonclinical study or clinical trial delays due to public health crises or other causes;

23

Table of Contents

• the initiation and successful patient enrollment and completion of additional clinical trials on a timely basis;

• establishing and maintaining relationships with CROs and clinical sites for the clinical development, both in the United States and internationally, of our product candidates and any future product candidates;

• the frequency and severity of adverse events in the clinical trials;

• the efficacy, safety and tolerability profiles that are satisfactory to the FDA, EMA, or any comparable foreign regulatory authority for obtaining marketing approval;

• timely receipt of marketing approvals from applicable regulatory authorities for any product candidates for which we successfully complete clinical development;

• making any required post-marketing approval commitments to applicable regulatory authorities;

• developing an efficient and scalable manufacturing process for our product candidates, including obtaining finished products that are appropriately packaged for sale;

• establishing and maintaining commercially viable supply and manufacturing relationships with third parties that can provide adequate, in both amount and quality, products and services to support clinical development and meet the market demand for product candidates that we develop, if approved;

• successful commercial launch following any marketing approval, including the development of a commercial infrastructure, whether in-house or with one or more collaborators;

• a continued acceptable safety profile following any marketing approval of our product candidates;

• commercial acceptance of our product candidates by patients, the medical community and third-party payors;

• identifying, assessing and developing new product candidates;

• obtaining, maintaining and expanding patent protection, trade secret protection and/or regulatory exclusivity;

• protecting our rights in our intellectual property portfolio;

• defending against third-party interference or infringement claims, if any;

• negotiating favorable terms in any collaboration, licensing or other arrangements that may be necessary or desirable to develop, manufacture or commercialize our product candidates;

• obtaining coverage and adequate reimbursement by hospitals, government and third-party payors for product candidates that we develop and receive regulatory approval;

• addressing any competing therapies and technological and market developments; and

• attracting, hiring and retaining qualified personnel.

We do not have complete control over many of these factors, including certain aspects of clinical development and the regulatory submission process, potential threats to our intellectual property rights and the manufacturing, marketing, distribution and sales efforts of any future collaborator. We may never be successful in achieving our objectives and, even if we do, may never generate revenue that is significant or large enough to achieve profitability. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable may decrease the value of our company and could impair our ability to maintain or further our research and development efforts, raise additional necessary capital, grow our business and continue our operations.

We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process or transferring that process to commercial partners, which may prevent us from completing our clinical trials or

24

Table of Contents

commercializing our product candidates on a timely or profitable basis, if at all. Changes in the manufacturing process or facilities will require further comparability analysis and approval by the FDA before implementation, which could delay our clinical trials and product candidate development, and could require additional clinical trials, including bridging studies, to demonstrate consistent and continued safety and potency.

We have not previously submitted a new drug application (“NDA”) to the FDA or similar approval filings to a comparable foreign regulatory authority, for any product candidate. An NDA or other relevant regulatory filing must include extensive nonclinical and clinical data and supporting information to establish that the product candidate is safe and effective for each desired indication. The NDA or other relevant regulatory filing must also include significant information regarding the chemistry, manufacturing and controls for the product. We cannot be certain that our current or future product candidates will be successful in clinical trials or receive regulatory approval. Further, even if such product candidates are successful in clinical trials, our product candidates or any future product candidates may not receive regulatory approval. If we do not receive regulatory approvals for current or future product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approval to market a product candidate, our revenue will depend, in part, upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights, as well as the availability of competitive products, whether there is sufficient third-party reimbursement and adoption by physicians.

If we breach any of the agreements under which we license rights to our product candidates or technology from third parties, we could lose license rights that are important to our business. Our current license agreement may not provide an adequate remedy for its breach by the licensor.

The Company is developing its Licensed Products (as defined in the Annual Information Form) pursuant to the amended and restated license agreement dated effective October 9, 2018 (the “Amended and Restated License Agreement”) with Auritec Pharmaceuticals Inc. (“Auritec”). The Company is subject to a number of risks associated with its collaboration with Auritec, including the risk that Auritec may terminate the Amended and Restated License Agreement upon the occurrence of certain specified events. The Amended and Restated License Agreement requires, among other things, that the Company make certain payments and use reasonable commercial efforts to meet certain clinical and regulatory milestones. If it fails to comply with any of these obligations or otherwise breaches this or similar agreements, Auritec or any future licensors may have the right to terminate the license in whole.

The Company could also suffer the consequences of non-compliance or breaches by licensors in connection with its license agreements. Such non-compliance or breaches by such third parties could in turn result in the Company’s breaches or defaults under its agreements with its other collaboration partners, and it could be found liable for damages or lose certain rights, including rights to develop and/or commercialize a product or product candidate. Loss of its rights to the Amended and Restated License Agreement or any similar license granted to the Company in the future, or the exclusivity rights provided therein, could harm the Company’s financial condition and operating results.

Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect the Company’s current and projected business operations and its financial condition and results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank (“SVB”) was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (“FDIC”) as receiver. Similarly, on March 12, 2023,

25

Table of Contents

Signature Bank and Silvergate Capital Corp. were each swept into receivership. Although a statement by the U.S. Department of the Treasury, the Federal Reserve and the FDIC indicated that all depositors of SVB would have access to all of their money after only one business day of closure, including funds held in uninsured deposit accounts, borrowers under credit agreements, letters of credit and certain other financial instruments with SVB, Signature Bank or any other financial institution that is placed into receivership by the FDIC may be unable to access undrawn amounts thereunder. In addition, if any of the Company’s suppliers or other parties with whom the Company conducts business are unable to access funds pursuant to such instruments or lending arrangements with such a financial institution, such parties’ ability to pay their obligations to us or to enter into new commercial arrangements requiring additional payments to us could be adversely affected. The Company currently is a borrower under the contingent convertible debt agreement with SVB with the facility being fully drawn. The Company, and any suppliers or other parties that are counterparties to SVB credit agreements and arrangements, and third parties such as beneficiaries of letters of credit (among others), may experience direct impacts from the closure of SVB and uncertainty remains over liquidity concerns in the broader financial services industry. Similar impacts have occurred in the past, such as during the 2008-2010 financial crisis.

Inflation and rapid increases in interest rates have led to a decline in the trading value of previously issued government securities with interest rates below current market interest rates. Although the U.S. Department of Treasury, FDIC and Federal Reserve Board announced a program to provide up to US$25 billion of loans to financial institutions secured by certain of such government securities held by financial institutions to mitigate the risk of potential losses on the sale of such instruments, widespread demands for customer withdrawals or other liquidity needs of financial institutions for immediately liquidity may exceed the capacity of such program. Additionally, there is no guarantee that the U.S. Department of Treasury, FDIC and Federal Reserve Board will provide access to uninsured funds in the future in the event of the closure of other banks or financial institutions, or that they would do so in a timely fashion.

Although the Company assesses its banking and customer relationships as it believes necessary or appropriate, the Company’s access to funding sources and other credit arrangements in amounts adequate to finance or capitalize the Company’s current and projected future business operations could be significantly impaired by factors that affect the Company, the financial institutions with which the Company has credit agreements or arrangements directly, or the financial services industry or economy in general. These factors could include, among others, events such as liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets, or concerns or negative expectations about the prospects for companies in the financial services industry. These factors could involve financial institutions or financial services industry companies with which the Company has financial or business relationships, but could also include factors involving financial markets or the financial services industry generally.

The results of events or concerns that involve one or more of these factors could include a variety of material and adverse impacts on the Company’s current and projected business operations and the Company’s financial condition and results of operations. These could include, but may not be limited to, the following:

• Delayed access to deposits or other financial assets or the uninsured loss of deposits or other financial assets;

• Delayed or lost access to, or reductions in borrowings available under revolving existing credit facilities or other working capital sources and/or delays, inability or reductions in the Company’s ability to refund, roll over or extend the maturity of, or enter into new credit facilities or other working capital resources;

• Potential or actual breach of contractual obligations that require the Company to maintain letters of credit or other credit support arrangements;

• Potential or actual breach of financial covenants in the Company’s credit agreements or credit arrangements;

26

Table of Contents

• Potential or actual cross-defaults in other credit agreements, credit arrangements or operating or financing agreements; or

• Termination of cash management arrangements and/or delays in accessing or actual loss of funds subject to cash management arrangements.

In addition, investor concerns regarding the U.S., Canadian, or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for the Company to acquire financing on acceptable terms or at all. Any decline in available funding or access to the Company’s cash and liquidity resources could, among other risks, adversely impact the Company’s ability to meet its operating expenses, financial obligations or fulfill its other obligations, result in breaches of the Company’s financial and/or contractual obligations or result in violations of federal or state wage and hour laws. Any of these impacts, or any other impacts resulting from the factors described above or other related or similar factors not described above, could have a material adverse effect on the Company’s liquidity and its current and/or projected business operations and financial condition and results of operations.

In addition, any further deterioration in the macroeconomic economy or financial services industry could lead to losses or defaults by the Company’s counterparties, which in turn, could have a material adverse effect on the Company’s current and/or projected business operations and results of operations and financial condition. For example, counterparties may fail to make payments when due, default under their agreements with us, become insolvent or declare bankruptcy, or a supplier may determine that it will no longer deal with us as a customer. In addition, a counterparty could be adversely affected by any of the liquidity or other risks that are described above as factors that could result in a material adverse effect on the Company, including but not limited to delayed access or loss of access to uninsured deposits or loss of the ability to draw on existing credit facilities involving a troubled or failed financial institution. Any counterparty bankruptcy or insolvency, or the failure of any counterparty to make payments when due, or any breach or default by a counterparty, or the loss of any significant supplier relationships, could result in material losses to the Company and may have a material adverse effect on the Company’s business.

Clinical trials are expensive, time consuming and difficult to design and implement and may fail to demonstrate adequate safety and efficacy of our product candidates. Furthermore, the results of previous preclinical studies and clinical trials may not be predictive of future results, and the results of our current and planned clinical trials may not satisfy the requirements of the FDA or comparable foreign regulatory authorities or provide the basis for regulatory approval.

Before obtaining marketing approval from regulatory authorities for the sale of our product candidates, we must conduct preclinical development and then extensive clinical trials to demonstrate their safety and efficacy. Preclinical and clinical testing is expensive and difficult to design and implement. Preclinical and clinical testing can take many years to complete, and its ultimate outcome is uncertain.

A failure of one or more preclinical or clinical trials can occur at any stage of the process. We will be required to demonstrate with substantial evidence through well-controlled clinical trials that our product candidates are safe and effective for use in a diverse patient population before we can seek regulatory approvals for their commercial sale. Our preclinical or clinical trials may produce negative or inconclusive results, and we may decide, or regulators may require us, to conduct additional and expansive preclinical or clinical testing.

Positive or timely results from preclinical or early-stage trials do not ensure positive or timely results in future clinical trials or registrational clinical trials because product candidates in later-stage clinical trials may fail to demonstrate sufficient safety and efficacy to the satisfaction of the FDA and comparable foreign regulatory authorities, despite having progressed through preclinical studies or initial clinical trials. Product candidates that have shown promising results in early clinical trials may still suffer significant setbacks in subsequent clinical trials or registration clinical trials. For example, a number of companies in the pharmaceutical industry, including

27

those with greater resources and experience than us, have suffered significant setbacks in advanced clinical trials, even after obtaining promising results in earlier clinical trials.

Our lead product candidate may not be successful for its intended use.

The Company’s primary drug candidate, EP-104IAR, is intended as a long-acting pain relief for OA knee pain. The active pharmaceutical ingredient is an anti-inflammatory corticosteroid fluticasone propionate (“FP”) that reduces the pain associated with inflammation. Inflammation is not the only contributor to knee pain, and EP-104IAR may not provide sufficient pain relief for other sources of pain, such as bone-on-bone interactions. EP-104IAR is the first extended release FP-based product candidate to be tested in the knee and the effective dose has not been determined. To achieve regulatory approval in North America, EP-104IAR must show significant benefit over placebo. This is complicated by the “placebo effect” in pain-related trials, whereby patients perceive pain relief despite having received no active pharmaceutical.

We have not received FDA approval for EP-104IAR and cannot be certain that our approach will lead to the development of an approvable or marketable product. We may not succeed in demonstrating safety and efficacy of EP-104IAR in our ongoing clinical trials or in larger-scale clinical trials.

Advancing EP-104IAR creates significant challenges for us, including:

• obtaining marketing approval, as the FDA, EMA or other regulatory authorities have never approved an FP-based product for OA knee pain;

• if EP-104IAR is approved, educating medical personnel regarding the potential benefits, as well as the challenges, of incorporating our EP-104IAR into existing treatment regimens, including in combination with other treatments for OA; and

• establishing the sales and marketing capabilities upon obtaining any marketing approvals to gain market acceptance.

Our current and future product candidates will require regulatory approval, which is costly, and we may not be able to obtain it and we may fail to obtain regulatory approvals or only obtain approvals for limited uses or indications.

Marketing authorization of EP-104IAR and other product candidates will fall under the regulatory purview of the FDA and other equivalent regulatory bodies worldwide. We are not permitted to commercialize, market, promote or sell any product candidate in the United States without obtaining marketing approval from the FDA. Foreign regulatory authorities impose similar requirements. The time required to obtain approval by the FDA, EMA and other comparable foreign regulatory authorities is unpredictable, typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the type, complexity and novelty of the product candidates involved. In addition, approval policies, regulations or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions or change over time, which may cause delays in the approval or the decision not to approve an application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical or other data. Even if we eventually complete clinical testing and receive approval of any regulatory filing for our product candidates, the FDA, EMA and other comparable foreign regulatory authorities may approve our product candidates for a more limited indication, a narrower patient population than we originally requested or with a Risk Evaluation and Mitigation Strategy (“REMS”). Further, regulatory authorities may not approve the price we intend to charge for products we may develop, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. We have not submitted for, or obtained, regulatory approval for any product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain regulatory approval.

28

Table of Contents

Further, development of our product candidates and/or regulatory approval may be delayed for reasons beyond our control. For example, a U.S. federal government shutdown or budget sequestration, may result in significant reductions to the FDA’s budget, employees and operations, which may lead to slower response times and longer review periods, potentially affecting our ability to progress development of our product candidates or obtain regulatory approval for our product candidates. Applications for our product candidates could fail to receive regulatory approval for many reasons, including the following:

• the FDA, EMA or other comparable foreign regulatory authorities may disagree with the design, implementation or results of our clinical trials;

• the FDA, EMA or other comparable foreign regulatory authorities may determine that our product candidates are not safe and effective, only moderately effective or have undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use;

• the population studied in the clinical trial may not be sufficiently broad or representative to assure efficacy and safety in the full population for which we seek approval;

• the FDA, EMA or other comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;

• the data collected from clinical trials of our product candidates may not be sufficient to support the submission of an NDA or other submission or to obtain regulatory approval in the United States or elsewhere;

• we may be unable to demonstrate to the FDA, EMA or other comparable foreign regulatory authorities that a product candidate’s risk-benefit ratio for its proposed indication is acceptable;

• the FDA, EMA or other comparable foreign regulatory authorities may fail to approve the manufacturing processes, test procedures and specifications or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and

• the approval policies or regulations of the FDA, EMA or other comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.

The clinical trials of our product candidates may not demonstrate safety and efficacy to the satisfaction of the FDA, EMA or other comparable foreign regulatory authorities or otherwise produce positive results.

Before obtaining marketing approval from the FDA, EMA or other comparable foreign regulatory authorities for the sale of our product candidates, we must complete preclinical development and extensive clinical trials to demonstrate the safety and efficacy of our product candidates. Clinical testing is expensive, difficult to design and implement, can take many years to complete and its ultimate outcome is uncertain. A failure of one or more clinical trials can occur at any stage of the process. The outcome of preclinical studies and early stage clinical trials may not be predictive of the success of later clinical trials. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their drugs. The outcome of preclinical studies and early-stage clinical trials may not be predictive of the success of later clinical trials.

In addition, we may rely in part on preclinical, clinical and quality data generated by CROs and other third parties for regulatory submissions for our product candidates. While we have or will have agreements governing these third parties’ services, we have limited influence over their actual performance. If these third parties do not make data available to us, or, if applicable, make regulatory submissions in a timely manner, in each case pursuant to our agreements with them, our development programs may be significantly delayed, and we may need to conduct additional studies or collect additional data independently. In either case, our development costs would increase.

Table of Contents

We do not know whether our future clinical trials will begin on time or enroll patients on time, or whether our ongoing and/or future clinical trials will be completed on schedule or at all. Clinical trials can be delayed for a variety of reasons, including delays related to:

• the FDA or comparable foreign regulatory authorities disagreeing as to the design or implementation of our clinical studies;

• obtaining regulatory authorizations to commence a trial or reaching a consensus with regulatory authorities on trial design;

• any failure or delay in reaching an agreement with CROs and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

• obtaining approval from one or more institutional review boards (“IRBs”);

• IRBs refusing to approve, suspending or terminating the trial at an investigational site, precluding enrollment of additional subjects, or withdrawing their approval of the trial;

• changes to clinical trial protocol;

• clinical sites deviating from trial protocol or dropping out of a trial;

• manufacturing sufficient quantities of product candidate or obtaining sufficient quantities of combination therapies for use in clinical trials;

• subjects failing to enroll or remain in our trial at the rate we expect, or failing to return for post- treatment follow-up;

• subjects choosing an alternative treatment for the indication for which we are developing our product candidates, or participating in competing clinical trials;

• lack of adequate funding to continue the clinical trial;

• subjects experiencing severe or unexpected drug-related adverse effects;

• occurrence of serious adverse events in trials of the same class of agents conducted by other companies;

• selection of clinical end points that require prolonged periods of clinical observation or analysis of the resulting data;

• a facility manufacturing our product candidates or any of their components being ordered by the FDA or comparable foreign regulatory authorities to temporarily or permanently shut down due to violations of current good manufacturing practice (“cGMP”), regulations or other applicable requirements, or infections or cross-contaminations of product candidates in the manufacturing process;

• any changes to our manufacturing process that may be necessary or desired;

• third-party clinical investigators losing the licenses or permits necessary to perform our clinical trials, not performing our clinical trials on our anticipated schedule or consistent with the clinical trial protocol, good clinical practices (“GCPs”) or other regulatory requirements;

• third-party contractors not performing data collection or analysis in a timely or accurate manner; or

• third-party contractors becoming debarred or suspended or otherwise penalized by the FDA or other government or regulatory authorities for violations of regulatory requirements, in which case we may need to find a substitute contractor, and we may not be able to use some or all of the data produced by such contractors in support of our marketing applications.

We could also encounter delays if a clinical trial is suspended or terminated by us, by the IRBs of the institutions in which such trials are being conducted, by a Data Safety Monitoring Board for such trial or by the FDA or

30

Table of Contents

comparable foreign regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. In addition, changes in regulatory requirements and policies may occur, and we may need to amend clinical trial protocols to comply with these changes. Amendments may require us to resubmit our clinical trial protocols to IRBs for reexamination, which may impact the costs, timing or successful completion of a clinical trial.

Further, conducting clinical trials in foreign countries, as we may do for our product candidates, presents additional risks that may delay completion of our clinical trials. These risks include the failure of enrolled patients in foreign countries to adhere to clinical protocol as a result of differences in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory schemes, as well as political and economic risks relevant to such foreign countries.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us from time to time and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable foreign regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates.

If we experience delays in the completion of, or termination of, any clinical trial of our product candidates, the commercial prospects of our product candidates will be harmed, and our ability to generate product revenues from any of these product candidates will be delayed. Moreover, any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenues.

In addition, many of the factors that cause, or lead to, termination or suspension of, or a delay in the commencement or completion of, clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate. Any delays to our clinical trials that occur as a result could shorten any period during which we may have the exclusive right to commercialize our product candidates and our competitors may be able to bring products to market before we do, and the commercial viability of our product candidates could be significantly reduced. Any of these occurrences may harm our business, financial condition and prospects significantly.

We completely rely on third parties to provide supplies and inputs required for our products.

We currently outsource all product manufacturing. The field of manufacturers capable of manufacturing the EP-104 API powder is narrow and not easily replaced. Although we depend heavily on these parties, we do not control them and, therefore, cannot be assured that these third parties will adequately perform all of their contractual obligations to us. If our third-party service providers cannot adequately fulfill their obligations to us in a timely and satisfactory basis, development plans may be delayed or terminated.

We expect to continue to rely on third-party manufacturers for the commercial supply of any of our product candidates for which we obtain marketing approval. We may be unable to maintain or establish required agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish

31

Table of Contents

agreements with third-party manufacturers, reliance on third-party manufacturers entails additional risks, including:

• the failure of the third party to manufacture our product candidates according to our schedule, or at all, including if our third-party contractors give greater priority to the supply of other products over our product candidates or otherwise do not satisfactorily perform according to the terms of the agreements between us and them;

• the reduction or termination of production or deliveries by suppliers, or the raising of prices or renegotiation of terms;

• the termination or nonrenewal of arrangements or agreements by our third-party contractors at a time that is costly or inconvenient for us;

• the breach by the third-party contractors of our agreements with them;

• the failure of third-party contractors to comply with applicable regulatory requirements;

• the failure of the third party to manufacture our product candidates according to our specifications;

• the mislabeling of clinical supplies, potentially resulting in the wrong dose amounts being supplied or active drug or placebo not being properly identified;

• clinical supplies not being delivered to clinical sites on time, leading to clinical trial interruptions, or of drug supplies not being distributed to commercial vendors in a timely manner, resulting in lost sales; and

• the misappropriation of our proprietary information, including our trade secrets and know-how.

We do not have complete control over all aspects of the manufacturing process of, and are dependent on, our contract manufacturing partners for compliance with cGMP regulations for manufacturing both active drug substances and finished drug products. Third-party manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements internationally. If our contract manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA, EMA or others, they will not be able to secure and/or maintain marketing approval for their manufacturing facilities. In addition, we do not have control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel. If the FDA, EMA or a comparable foreign regulatory authority does not approve these facilities for the manufacture of our product candidates or if it withdraws any such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain marketing approval for or market our product candidates, if approved. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our product candidates or drugs and harm our business and results of operations. Our current and anticipated future dependence upon others for the manufacture of our product candidates or drugs may adversely affect our future profit margins and our ability to commercialize any product candidates that receive marketing approval on a timely and competitive basis.

We rely on CROs to provide clinical and non-clinical research services; if such CROs do not successfully carry out their contractual duties including to comply with applicable laws and regulations or meet expected deadlines, our business could be substantially harmed.

The Company anticipates engaging CROs for most aspects of the Company’s clinical trials, including trial conduct, data management, study management and managing, statistical analysis and electronic compilation of the Company’s regulatory submissions. The Company may enter into agreements with CROs to obtain resources

32

Table of Contents

and expertise in an attempt to accelerate the Company’s progress on new or ongoing clinical and non-clinical programs. Typically entering into relationships with CROs involves substantial cost and requires extensive management time and focus. In addition, typically there is a transition period between engagement of a CRO and the time the CRO commences work. As a result, delays may occur, which may materially impact the Company’s ability to meet desired non-clinical and clinical development timelines and ultimately have a material adverse effect on the Company’s operating results, financial condition or future prospects.

As CROs are not the Company’s employees, the Company cannot control whether or not they devote sufficient time and resources to the Company’s clinical trials for which they are engaged to perform, and whether they comply with the applicable GCPs and Good Laboratory Practices (“GLPs”) for the Company’s product candidates, which include requirements related to the conduct of the study, subject informed consent, and research ethics board’s approval among others. Regulatory authorities, including the FDA, monitor compliance with Good Manufacturing Practices, GLPs, and GCPs (collectively, “GxPs”) through periodic inspections of trial sponsors, principal investigators and trial sites. Although the Company may rely on third parties for the execution of the Company’s clinical trials and non-clinical research, the Company is nevertheless responsible for ensuring that each of the Company’s studies is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and the Company’s reliance on CROs does not relieve the Company of the Company’s regulatory responsibilities. If the Company or any of the Company’s CROs fail to comply with applicable GCPs and GLPs, the data generated in the Company’s studies may be deemed unreliable and the applicable regulatory authorities may take regulatory action against the Company and/or require the Company to perform additional studies before approving the Company’s marketing applications. The Company cannot assure you that, upon inspection by a given regulatory authority, such regulatory authority will determine that any of the Company’s clinical trials complies with GCP regulations. In addition, the Company’s clinical trials must be conducted with product candidate materials produced under GMP regulations. the Company’s failure to comply with these regulations may require the Company to discontinue or repeat clinical trials, which would delay the regulatory approval process. If the CROs that the Company engages do not successfully carry out their contractual duties or obligations, conduct the studies in accordance with all regulatory requirements, or meet expected deadlines, or if they need to be replaced, or the quality or accuracy of the data they provide is compromised due to the failure to adhere to regulatory requirements or for other reasons, then the Company’s development programs may be extended, delayed or terminated, or the Company may not be able to obtain marketing approval for or successfully commercialize the Company’s product candidates. Failure to comply with clinical trial regulatory requirements may further subject the Company to significant penalties potentially including imprisonment or an injunction against manufacture or distribution and debarment.

The manufacture of drugs is complex and our third-party manufacturers may encounter difficulties in production. If any of our third-party manufacturers encounter such difficulties, our ability to provide adequate supply of our product candidates for clinical trials or our products for patients, if approved, could be delayed or prevented.

Manufacturing drugs, especially in large quantities, is complex and may require the use of innovative technologies. Each lot of an approved drug product must undergo thorough testing for identity, strength, quality, purity, potency, and stability. Manufacturing drugs requires facilities specifically designed for and validated for this purpose, and sophisticated quality assurance and quality control procedures are necessary. Slight deviations anywhere in the manufacturing process, including filling, labeling, packaging, storage and shipping and quality control and testing, may result in lot failures, product recalls or spoilage. When changes are made to the manufacturing process, we may be required to provide preclinical and clinical data showing the comparable identity, strength, quality, purity or potency of the products before and after such changes. If microbial, viral or other contaminations are discovered at the facilities of our manufacturer, such facilities may need to be closed for an extended period of time to investigate and remedy the contamination, which could delay clinical trials and adversely harm our business, including exposure to liabilities arising from any GxP non-compliance. If our manufacturers and suppliers are unable to produce sufficient quantities for clinical trials or for commercialization as a result of these challenges, or otherwise, our development and commercialization efforts would be impaired,

33

Table of Contents

which would have an adverse effect on our business, financial condition, results of operations and growth prospects.

The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and the results of our clinical trials may not satisfy the requirements of the FDA, EMA or other comparable foreign regulatory authorities. Terminating the development of any of our product candidates could materially harm our business and the market price of our common shares.

Our clinical product candidates, along with product candidates we expect to enter clinical development, are in varying stages of development and will require substantial clinical development, testing and regulatory approval prior to commercialization. Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive pre-clinical testing and clinical trials that each product candidate is both safe and effective for use in each target indication. Failure can occur at any time during the clinical trial process. Clinical trials often fail to demonstrate safety and efficacy of the product candidate studied for the target indication. Most product candidates that commence clinical trials are never approved as products. A number of companies in the pharmaceutical industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials. In some instances, there can be significant variability in safety and efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in trial protocols, differences in size and type of the patient populations, differences in and adherence to the dosing regimen and other trial protocols and the rate of dropout among clinical trial participants. Patients treated with our product candidates may also be undergoing other treatments and may be using other approved products or investigational new drugs, which can cause side effects or adverse events that are unrelated to our product candidate. As a result, assessments of efficacy can vary widely for a particular patient, and from patient to patient and site to site within a clinical trial. This subjectivity can increase the uncertainty of, and adversely impact, our clinical trial outcomes.

In addition to the safety and efficacy trials of any product candidate, clinical trial failures may result from a multitude of factors including flaws in trial design, dose selection, statistical analysis plan, placebo effect, patient enrollment criteria, patient compliance and trial execution. Data obtained from trials and studies are susceptible to varying interpretations, and regulators may not interpret our data as favorably as we do, which may delay, limit or prevent regulatory approval. Failure of a clinical trial due to any of these reasons could materially harm our business and the market price of our common shares. In the case of some of our product candidates, we may seek to develop treatments for certain diseases or disorders for which there is relatively limited clinical experience, and clinical trials may use novel endpoints and measurement methodologies or subjective patient feedback, which adds a layer of complexity to these clinical trials and may delay regulatory approval. Negative or inconclusive results from our clinical trials could lead to a decision or requirement to conduct additional pre-clinical testing or clinical trials or result in a decision to terminate the continued development of a product candidate. Any of the foregoing outcomes would materially and adversely impact our business, product candidate pipeline and future prospects.

If our product candidates are not shown to be both safe and effective in clinical trials, such product candidates will be unable to obtain regulatory approval or be successfully commercialized. In addition, our failure to demonstrate positive results in clinical trials in any indication for which we are developing clinical product candidates could adversely affect development efforts in other indications. In such case, we would need to develop other compounds and conduct associated pre-clinical testing and clinical trials, as well as potentially seek additional financing, all of which would have a material adverse effect on our business, growth prospects, operating results, financial condition and results of operations.

Interim, initial, “top-line”, and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary or top-line data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the top-line or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, top-line data should be viewed with caution until the final data are available.

Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available or as patients from our clinical trials continue other treatments for their disease. Adverse differences between preliminary or interim data and final data could significantly harm our business prospects. Further, disclosure of interim data by us or by our competitors could result in volatility in the price of our Common Shares.

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line, or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or financial condition.

Any safety concerns observed in any one of our clinical trials in our targeted indications could limit the prospects for regulatory approval of our product candidates in those and other indications, which could seriously harm our business.

Preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA, EMA or comparable foreign regulatory authority approval. We cannot guarantee that the FDA or foreign regulatory authorities will interpret trial results as we do, and more trials could be required before we are able to submit applications seeking approval of our product candidates. To the extent that the results of the trials are not satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, we may be required to expend significant resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates. Even if regulatory approval is secured for any of our product candidates, the terms of such approval may limit the scope and use of our product candidate, which may also limit its commercial potential. Furthermore, the approval policies or regulations of the FDA, EMA or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval, which may lead to the FDA, EMA or comparable foreign regulatory authorities delaying, limiting or denying approval of our product candidates.

Our current or future product candidates may cause significant adverse events, toxicities or other undesirable side effects when used alone or in combination with other products that may result in a safety profile that could inhibit regulatory approval, prevent market acceptance, limit their commercial potential or result in significant negative consequences.

As is the case with pharmaceuticals generally, it is likely that there may be side effects and adverse events associated with our product candidates’ use. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities. The drug-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

If our product candidates are associated with undesirable side effects or have unexpected characteristics in preclinical studies or clinical trials when used alone or in combination with other approved products or investigational new drugs we may need to interrupt, delay or abandon their development or limit development to more narrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Treatment-related side effects could also affect patient recruitment or the ability of enrolled subjects to complete the trial, or result in potential product liability claims. Any of these occurrences may prevent us from achieving or maintaining market acceptance of the affected product candidate and may harm our business, financial condition and prospects significantly.

Patients in our ongoing and planned clinical trials may in the future suffer significant adverse events or other side effects not observed in our preclinical studies or previous clinical trials. Some of our product candidates, may be used as chronic therapies or be used in pediatric populations, for which safety concerns may be particularly scrutinized by regulatory agencies. In addition, if our product candidates are used in combination with other therapies, our product candidates may exacerbate adverse events associated with the therapy. Patients treated with our product candidates may also be undergoing other medical procedures or treatments, which can cause side effects or adverse events that are unrelated to our product candidate, but may still impact the success of our clinical trials.

If significant adverse events or other side effects are observed in any of our current or future clinical trials, we may have difficulty recruiting patients to the clinical trials, patients may drop out of our trials, or we may be required to abandon the trials or our development efforts of that product candidate altogether. We, the FDA, EMA, other comparable regulatory authorities or an IRB may suspend clinical trials of a product candidate at any time for various reasons, including a belief that subjects in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics developed in the biotechnology industry that initially showed therapeutic promise in early-stage trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance due to its tolerability versus other therapies. Any of these developments could materially harm our business, financial condition and prospects.

Further, if any of our product candidates obtains marketing approval, toxicities associated with such product candidates and not seen during clinical testing may also develop after such approval and lead to a requirement to conduct additional clinical safety trials, additional contraindications, warnings and precautions being added to the drug label, significant restrictions on the use of the product or the withdrawal of the product from the market. We cannot predict whether our product candidates will cause toxicities in humans that would preclude or lead to the revocation of regulatory approval based on preclinical studies or early-stage clinical trials.

Where appropriate and applicable, we may seek approval from the FDA or comparable foreign regulatory authorities through the use of expedited approval pathways, such as Fast Track designation or orphan drug designation. Even if we receive Fast Track designation or other designation, we can provide no assurance that we will be able to obtain FDA approval sooner or if at all.

Where possible, we may pursue accelerated development strategies in areas of high unmet need for one or more of our product candidates. In June 2023, we announced that the FDA has granted Fast Track designation for EP-104IAR in treatment of OA. Fast Track designation is designed to facilitate the development and expedite the review of therapies for serious conditions and fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communications with the FDA, potential priority review and the ability to submit a rolling application for regulatory review. Fast Track designation applies to both the product candidate and the specific indication for which it is being studied. If any of our product candidates receive Fast Track designation but do not continue to meet the criteria for Fast Track designation, or if our clinical trials are delayed, suspended or terminated, or put on clinical hold due to unexpected adverse events or issues with clinical supply, we will not receive the benefits associated with the Fast Track program. Furthermore, Fast Track designation does not change the standards for approval. Fast Track designation alone does not guarantee qualification for the FDA’s priority review procedures.

If we are unable to establish sales and marketing capabilities or enter into agreements with third parties to market and sell our drug candidates, if approved, we may be unable to generate any product revenue.

To successfully commercialize EP-104IAR, if approved, or any future product candidate that may result from our development programs, we will need to build out our sales and marketing capabilities, either on our own or with others. The establishment and development of our own commercial team or the establishment of a contract field force to market any product candidate we may develop will be expensive and time-consuming and could delay any drug launch. Moreover, we cannot be certain that we will be able to successfully develop this capability. We may seek to enter into collaborations with other entities to use their established marketing and distribution capabilities, but we may be unable to enter into such agreements on favorable terms, if at all. If any current or future collaborators do not commit sufficient resources to commercialize our product candidates, or we are unable to develop the necessary capabilities on our own, we may be unable to generate sufficient revenue to sustain our business. We may compete with many companies that currently have extensive, experienced and well-funded marketing and sales operations to recruit, hire, train and retain marketing and sales personnel. We will likely also face competition if we seek third parties to assist us with the sales and marketing efforts any future product candidates. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

We have a novel technology with uncertain market acceptance.

Even if any of our product candidates receive regulatory approval, the approved products may not achieve broad market acceptance among physicians, patients, the medical community and third-party payors, in which case revenue generated from their sales would be limited. Our delivery platform is at an early stage of development and uses novel technology, with uncertain market acceptance if our product candidates are approved. Product approval, should this be achieved, does not infer that the product will garner a good market price or be reimbursed by public or private insurers. Further, there are no guarantees that the product will be positively received by the target patient population. If any of our product candidates is approved but does not achieve an adequate level of acceptance by physicians, healthcare payors and patients, we may not generate or derive sufficient revenue from that product candidate and our financial results could be negatively impacted. The degree of market acceptance of any of our approved product candidates will depend on a number of factors, including, but not limited to:

• the efficacy and safety profile as demonstrated in clinical trials compared to alternative treatments;

• the timing of market introduction of the product candidate as well as competitive products;

37

Table of Contents

• the clinical indications for which the product candidate is approved;

• restrictions on the use of our product candidates, such as boxed warnings or contraindications in labeling, or a REMS, if any, which may not be required of alternative treatments and competitor products;

• the potential and perceived advantages of product candidates over alternative treatments;

• the cost of treatment in relation to alternative treatments;

• the availability of coverage and adequate reimbursement, as well as pricing, by third-party payors, including government authorities;

• the availability of the approved product candidate for use as a combination therapy;

• relative convenience and ease of preparation and administration;

• the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies;

• the effectiveness of sales and marketing efforts;

• unfavorable publicity relating to our products or product candidates or similar approved products or product candidates in development by third parties; and

• the approval of other new therapies for the same indications.

If we experience delays or difficulties in the enrollment and/or maintenance of patients in clinical trials, our clinical development activities could be delayed or otherwise adversely affected.

Patient enrollment is a significant factor in the timing of clinical trials, and the timing of our clinical trials depends, in part, on the speed at which we can recruit patients to participate in our trials, as well as completion of required follow-up periods. We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials to such trial’s conclusion as required by the FDA, EMA or other comparable foreign regulatory authorities. Additionally, certain clinical trials for future product candidates may be focused on indications with relatively small patient populations, which may further limit enrollment of eligible patients or may result in slower enrollment than we anticipate. The eligibility criteria of our clinical trials, once established, may further limit the pool of available trial participants.

Patient enrollment may also be affected if our competitors have ongoing clinical trials for product candidates that are under development for the same indications as our product candidates, and patients who would otherwise be eligible for our clinical trials instead enroll in clinical trials of our competitors’ product candidates. Patient enrollment for any of our clinical trials may be affected by other factors, including:

• size and nature of the patient population;

• severity of the disease under investigation;

• availability and potency of approved drugs for the disease under investigation;

• patient eligibility criteria for the trial in question as defined in the protocol;

• perceived risks and benefits of the product candidate under study;

• clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new products that may be approved for the indications we are investigating;

• efforts to facilitate timely enrollment in clinical trials;

38

Table of Contents

• patient referral practices of physicians;

• the ability to monitor patients adequately during and after treatment;

• proximity and availability of clinical trial sites for prospective patients;

• continued enrollment of prospective patients by clinical trial sites; and

• the risk that patients enrolled in clinical trials will drop out of the trials before completion.

Our inability to enroll a sufficient number of patients for our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates and jeopardize our ability to obtain marketing approval for the sale of our product candidates. Furthermore, even if we are able to enroll a sufficient number of patients for our clinical trials, we may have difficulty maintaining enrollment of such patients in our clinical trials.

The FDA, EMA and other comparable foreign regulatory authorities may not accept data from trials conducted in locations outside of their jurisdiction.

We may choose to conduct international clinical trials in the future. The acceptance of study data by the FDA, EMA or other comparable foreign regulatory authority from clinical trials conducted outside of their respective jurisdictions may be subject to certain conditions. In cases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (1) the data are applicable to the United States population and United States medical practice; (2) the trials are performed by clinical investigators of recognized competence and pursuant to current GCP requirements; and (3) the FDA is able to validate the data through an on-site inspection or other appropriate mean. Additionally, the FDA’s clinical trial requirements, including the adequacy of the patient population studied and statistical powering, must be met. In addition, such foreign trials would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA, EMA or any applicable foreign regulatory authority will accept data from trials conducted outside of its applicable jurisdiction. If the FDA, EMA or any applicable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may result in our product candidates not receiving approval for commercialization in the applicable jurisdiction.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of our product candidates in other jurisdictions.

Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction. For example, even if the FDA or EMA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion and reimbursement of the product candidate in those countries. However, a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States, including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval.

Obtaining foreign regulatory approvals and establishing and maintaining compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our products in certain countries. If we or any future collaborator fail to comply with the

39

Table of Contents

regulatory requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed.

If the market opportunity for any product candidate that we or our strategic partners develop is smaller than we believe, our revenue may be adversely affected and our business may suffer.

We intend to initially focus our product candidate development on treatments for OA and EoE indications. Our projections of addressable patient populations that may benefit from treatment with our product candidates are based on our estimates. These estimates, which have been derived from a variety of sources, including scientific literature, surveys of clinics, patient foundations and market research, may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of OA or EoE. Additionally, the potentially addressable patient population for our product candidates may not ultimately be amenable to treatment with our product candidates. FDA, EMA, or other regulatory agencies may also limit our proposed indication or target population. Our market opportunity may also be limited by future competitor treatments that enter the market. If any of our estimates prove to be inaccurate, the market opportunity for any product candidate that we or our strategic partners develop could be significantly diminished and have an adverse material impact on our business.

Even if our product candidates receive regulatory approval, they will be subject to significant post marketing regulatory requirements and oversight.

Any regulatory approvals that we may receive for our product candidates will require the submission of reports to regulatory authorities and surveillance to monitor the safety and efficacy of the product candidate, may contain significant limitations related to use restrictions for specified age groups, warnings, precautions or contraindications, and may include burdensome post-approval study or risk management requirements. For example, the FDA may require a REMS in order to approve our product candidates, which could entail requirements for a medication guide, physician training and communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or foreign regulatory authorities approve our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion, import, export and recordkeeping for our product candidates will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as on-going compliance with cGMPs and GCP for any clinical trials that we conduct post-approval. In addition, manufacturers of drug products and their facilities are subject to continual review and periodic, unannounced inspections by the FDA and other regulatory authorities for compliance with cGMP regulations and standards. If we or a regulatory agency discover previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facilities where the product is manufactured, a regulatory agency may impose restrictions on that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing.

In addition, failure to comply with FDA, EMA and other comparable foreign regulatory requirements may subject our company to administrative or judicially imposed sanctions, including:

• delays in or the rejection of product approvals;

• restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;

• restrictions on the products, manufacturers or manufacturing process;

• warning or untitled letters;

• civil and criminal penalties;

• injunctions;

40

Table of Contents

• suspension or withdrawal of regulatory approvals;

• product seizures, detentions or import bans;

• voluntary or mandatory product recalls and publicity requirements;

• total or partial suspension of production; and

• imposition of restrictions on operations, including costly new manufacturing requirements.

The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue and could require us to expend significant time and resources in response and could generate negative publicity.

FDA’s and other regulatory authorities’ policies may change, and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates.

If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, and we may not achieve or sustain profitability. We also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. If government regulation arises that puts constraints on FDA’s or other regulatory authorities’ ability to exercise their respective regulatory authority, including engaging in oversight and implementation activities in the normal course, our business may be negatively impacted.

The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses.

If any of our product candidates are approved and we are found to have improperly promoted off-label uses of those products, we may become subject to significant liability. The FDA and other regulatory agencies strictly regulate the promotional claims that may be made about prescription products, such as our product candidates, if approved. In particular, a product may not be promoted for uses that are not approved by the FDA or such other regulatory agencies as reflected in the product’s approved labeling. If we receive marketing approval for a product candidate, physicians may nevertheless prescribe it to their patients in a manner that is inconsistent with the approved label. If we are found to have promoted such off-label uses, we may become subject to significant liability. The U.S. federal government has levied large civil and criminal fines against companies for alleged improper promotion of off-label use and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. If we cannot successfully manage the promotion of our product candidates, if approved, we could become subject to significant liability, which would materially adversely affect our business and financial condition.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes, and other events that may otherwise affect the FDA’s ability to perform routine functions. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of other government agencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

41

Table of Contents

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, in 2018 and 2019, the U.S. government shut down several times and certain regulatory agencies, such as the FDA, had to furlough critical employees and stop critical activities. Separately, in response to the COVID-19 pandemic, the FDA temporarily postponed certain inspections before resuming normal operations.

If a prolonged government shutdown occurs, or if global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

We rely on key personnel.

The Company’s success depends in large measure on certain key personnel, including our executive officers. The loss of the services of such key personnel could have a material adverse effect on the Company. The contributions of these individuals to the Company’s immediate operations are likely to be of central importance. In addition, the competition for qualified personnel in the biotech industry is intense and there can be no assurance that the Company will be able to continue to attract and retain all personnel necessary for the development and operation of the Company’s business. Investors must rely upon the ability, expertise, judgment, discretion, integrity and good faith of the Company’s management. Other biotechnology companies with which the Company competes for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than the Company does. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates than those that the Company has to offer. If the Company is unable to continue to attract and retain high-quality personnel, the rate of and success with which the Company can develop and commercialize product candidates would be limited.

As a technology-driven company, intellectual input from key management and personnel is critical to achieve our business objectives. Consequently, our ability to retain these individuals and attract other qualified individuals is critical to our success. The loss of the services of key individuals might significantly delay or prevent achievement of our business objectives. In addition, because of a relative scarcity of individuals with the high degree of education and scientific achievement required for our business, competition among biotech companies for qualified employees is intense, and as a result we may not be able to attract and retain such individuals on acceptable terms, or at all.

We also have relationships with scientific collaborators at academic and other institutions, some of whom conduct research at our request or assist us in formulating our research and development strategies. These scientific collaborators are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us. In addition, even though our collaborators are required to sign confidentiality agreements prior to working with us, they may have arrangements with other companies to assist such other companies in developing technologies that may prove competitive to us.

Incentive provisions for our key executives include the granting of stock options that vest over time, designed to encourage such individuals to stay with us. However, a low share price could render such agreements of little value to our key executives. In such event, our key executives could be susceptible to being hired away by our competitors who could offer a better compensation package. If we are unable to attract and retain key personnel our business, financial conditions and results of operations may be adversely affected.

We may not be able to successfully execute our business strategy.

The execution of our business strategy poses many challenges and is based on several assumptions. If we experience significant regulatory delays, supply chain disruptions, cost overruns on our programs, or if our

42

Table of Contents

business plan is more costly than we anticipate, certain research and development activities may be delayed or eliminated, resulting in changes or delays to our commercialization plans, or we may be compelled to secure additional funding (which may or may not be available) to execute our business strategy. We cannot predict with certainty our future revenues or results from our operations. If the assumptions on which our revenue or expenditure forecasts are based change, the benefits of our business strategy may change as well.

We are in a highly competitive industry which is continuously evolving with technological changes.

The Company is engaged in an industry that is highly competitive, evolving and characterized by technological change. As a result, it is difficult for it to predict whether, when and by whom new competing technologies or new competitors may enter the market. The Company faces competition from companies with strong positions in certain markets it is currently targeting, and in new markets and regions it may enter. Some of these companies have significantly greater financial, technical, human, research and development, and marketing resources than the Company. The Company cannot assure that it will be able to compete effectively against current and future competitors who may discover and develop products in advance of the Company that are more effective than those developed by the Company. As a consequence, the Company’s current and future technologies may become obsolete or uncompetitive, resulting in adverse effects on revenue, margins and profitability. In addition, competition or other competitive pressures may result in price reductions, reduced margins or loss of market share, any of which could have a material adverse effect on the Company’s business, financial condition or results of operations. To the extent that new or improved oral or other systemically administered pain medications are introduced that demonstrate better long-term efficacy and safety, patients and physicians may further delay the introduction of injectable therapies, such as EP-104IAR, if approved, in the OA treatment continuum. EP-104IAR could also face competition from other formulations or devices that deliver pain medication on an extended basis, such as transdermal delivery systems or implantable devices.

Many of the Company’s competitors have substantially greater financial, technical and other resources, such as larger research and development staffs and experienced commercial and manufacturing organizations. Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated in the Company’s competitors. As a result, these companies may obtain regulatory approval more rapidly than the Company is able and may be more effective in selling and marketing their products as well. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Competitors may succeed in developing, acquiring or licensing on an exclusive basis drug products or drug delivery technologies that are more effective or less costly than EP-104IAR or any other product candidate that the Company is currently developing or may develop.

The Company believes that its ability to compete effectively depends upon many factors both within and beyond the Company’s control, including:

• the usefulness, ease of use, performance and reliability of the Company’s technology compared to its competitors;

• the activity and tolerability of EP-104IAR and the Company’s other product candidates, including relative to marketed products and product candidates in development by third parties;

• the ability to distinguish safety and efficacy from existing, alternative therapies;

• the timing for product candidates to complete clinical development and receive market approval;

• acceptance of EP-104IAR and any of the Company’s other product candidates that receive regulatory approval by patients, physicians and other health providers;

• the Company’s ability to monetize its technology;

43

Table of Contents

• the selection of licensing partners for its technology with the necessary skills and resources to drive uptake;

• the Company’s marketing and selling efforts;

• the Company’s financial condition and results of operations;

• the ability to maintain a good relationship with regulatory authorities;

• the price of the Company’s future products, including in comparison to branded or generic competitors;

• whether coverage and adequate levels of reimbursement are available under private and governmental health insurance plans;

• acquisitions or consolidations within the Company’s industry, which may result in more formidable competitors;

• the Company’s ability to protect its intellectual property rights;

• the Company’s ability to attract, retain and motivate talented employees;

• the Company’s ability to cost-effectively manage and grow its operations; and

• the Company’s reputation and brand strength relative to that of its competitors.

Our future success will depend on our ability to continually enhance and develop our product candidates.

There is a broad pipeline of potential new therapies for OA pain. The OA market is characterized by rapid technological change and the possibility of frequent new product introductions. Accordingly, the Company’s future success depends upon its ability to enhance its current product candidates and to develop, introduce and sell the most accurate products at competitive prices. The development of new technologies and products involves time, substantial costs and risks. The Company’s ability to successfully develop new technologies depends in large measure on its ability to maintain a technically skilled research and development staff and to adapt to technological changes and advances in the industry.

The success of new product introductions depends on a number of factors including the efficacy and safety as demonstrated in clinical trials, the ability to demonstrate the impact of real world evidence, timely and successful product development, the timing and market introduction of competitive products, market acceptance, the effective management of purchase commitments and inventory levels in line with anticipated product demand, the availability of pharmaceutical components in appropriate quantities and costs to meet anticipated demand, the risk that new products may have quality or other defects in the early stages of introduction and the Company’s ability to manage distribution and production issues related to new product introductions, the clinical indications for which the product is approved, acceptance by physicians, the medical community and patients of the product as a safe and effective treatment, the ability to distinguish safety and efficacy from existing, less expensive alternative therapies, the convenience of prescribing, administrating and initiating patients on the product, the potential and perceived advantages and/or value of the product over alternative treatments, the cost of treatment in relation to alternative treatments, including any similar generic treatments, the availability of coverage and adequate reimbursement by third-party payors and government authorities to support the product’s pricing, the prevalence and severity of adverse side effects and the effectiveness of sales and marketing efforts.

If the Company is unable, for any reason, to enhance, develop, introduce and sell new products in a timely manner, or at all, in response to changing market conditions or customer requirements or otherwise, its business would be harmed.

Even if the Company successfully advances any other product candidates into clinical development, their success will be subject to all of the clinical, regulatory and commercial risks described elsewhere in this “Risk Factors” section. Accordingly, the Company cannot assure you that it will ever be able to discover, develop, obtain regulatory approval of, commercialize or generate significant revenue from its product candidates.

We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we focus on research programs, therapeutic platforms and product candidates that we identify for specific indications. As a result, we may forgo or delay pursuit of opportunities with other therapeutic platforms or product candidates or for other indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs, therapeutic platforms and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights.

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay.

As product candidates progress through preclinical and clinical trials to marketing approval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize yield and manufacturing batch size, minimize costs and achieve consistent quality and results. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the altered materials. This could delay completion of clinical trials, require the conduct of bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates and jeopardize our ability to commercialize our product candidates, if approved, and generate revenue.

If we are unable to differentiate EP-104IAR from existing generic therapies for treatment of OA, or if the FDA or other applicable regulatory authorities approve generic products that compete with EP-104IAR, our ability to successfully commercialize EP-104IAR would be adversely affected.

Immediate-release triamcinolone acetonide (“TCA”) and other injectable immediate-release steroids, which are the current intra-articular standard of care for OA pain, are available in generic form and are therefore relatively inexpensive compared to the potential pricing for EP-104IAR. Although we believe our Phase 2 study provides preliminary evidence of extended pain relief, it is possible that we will receive data from additional clinical trials or in a post marketing setting from physician and patient experiences with the commercial product that does not continue to support such interpretations. It is also possible that the FDA, physicians and healthcare payors will not agree with our interpretation of our existing and future clinical trial data. If we are unable to demonstrate the value of EP-104IAR based on our clinical data, patient experience, as well as real world evidence, our opportunity for EP-104IAR to obtain premium pricing and be commercialized successfully would be adversely affected.

In addition to existing generic steroids, such as immediate-release TCA, the FDA or other applicable regulatory authorities may approve other generic products that could compete with EP-104IAR if we cannot adequately protect it with our patent portfolio. For example, in the United States, once an NDA, including a Section 505(b)(2) application, is approved, the product covered thereby becomes a “listed drug” which can, in turn, be cited by potential competitors in support of approval of an abbreviated new drug application (“ANDA”). The Federal Food, Drug, and Cosmetic Act, FDA regulations and other applicable regulations and policies provide incentives to manufacturers to create modified, non-infringing versions of a drug to facilitate the approval of an ANDA or other application for generic substitutes. These manufacturers might only be required to conduct a relatively inexpensive study to show that their product has the same active ingredient(s), dosage form,

45

Table of Contents

strength, route of administration, conditions of use, or labeling as our product candidate and that the generic product is bioequivalent to ours, meaning it is absorbed in the body at the same rate and to the same extent as EP-104IAR. These generic equivalents, which must meet the same quality standards as branded pharmaceuticals, would be significantly less costly than ours to bring to market and companies that produce generic equivalents are generally able to offer their products at lower prices. Thus, after the introduction of a generic competitor, a significant percentage of the sales of any branded product is typically lost to the generic product. Accordingly, competition from generic equivalents to our products would materially adversely impact our ability to successfully commercialize EP-104IAR.

A variety of risks associated with potential international business relationships could materially adversely affect our business.

The Company may enter into agreements with third parties for the development and commercialization of EP-104IAR and other product candidates in international markets. If the Company does so, the Company would be subject to additional risks related to entering into international business relationships, including:

• differing regulatory requirements in other countries including, among others, marketing approval, pricing, reimbursement and sales and marketing practices;

• potentially reduced protection for intellectual property rights;

• potential for so-called parallel importing, which is when a local seller, faced with higher local prices, opts to import goods from a foreign market with lower prices, rather than buying them locally;

• unexpected changes in tariffs, trade barriers and regulatory requirements;

• economic weakness, including inflation, or political instability in foreign economies and markets;

• compliance with tax, employment, immigration and labor laws for employees traveling and working abroad;

• foreign taxes;

• foreign currency fluctuations, which could result in increased operating expenses and reduced revenues, and other risks incident to doing business in another country;

• workforce uncertainty in countries where labor unrest is more common than in Canada or the United States;

• production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad or supply chain disruptions; and

• business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters, including earthquakes, volcanoes, typhoons, floods, tsunamis, hurricanes and fires.

These and other risks may materially adversely affect the Company’s ability to develop and commercialize products in international markets and may harm the Company’s business.

Collaboration arrangements we may enter into in the future may not be successful.

The Company may seek future partnerships, collaborations and other strategic transactions to maximize the commercial potential of EP-104IAR and our other product candidates. The Company may enter into such arrangements on a selective basis depending on the merits of retaining commercialization rights for itself as compared to entering into selective collaboration arrangements with leading pharmaceutical or biotechnology companies for EP-104IAR and other product candidates, both in the United States and internationally. The Company faces competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time consuming to negotiate, document and implement. The Company may not be successful in its

46

Table of Contents

efforts to establish and implement collaborations or other alternative arrangements should the Company choose to enter into such arrangements. The terms of any collaborations or other arrangements that the Company may establish may not be favorable to the Company.

Any future collaborations that the Company enters into may not be successful. The success of the Company’s collaboration arrangements will depend heavily on the efforts and activities of the Company’s collaborators. Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations.

Disagreements between parties to a collaboration arrangement regarding clinical development and commercialization matters could lead to delays in the development process or commercialization of the Company’s product candidates and in some cases, termination of the collaboration arrangement. These disagreements can be difficult to resolve if neither of the parties has final decision-making authority.

Collaborations with pharmaceutical or biotechnology companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration could adversely affect the Company financially and could harm the Company’s business reputation.

We may acquire businesses or products, or form strategic alliances in the future, and we may not realize the benefits of such acquisitions or alliances.

The Company may acquire additional businesses or products, form strategic alliances or create joint ventures with third parties that the Company believes will complement or augment the Company’s existing business. If the Company acquires businesses with promising markets or technologies, the Company may not be able to realize the benefit of acquiring such businesses if the Company is unable to successfully integrate them with the Company’s existing operations and company culture. The Company may encounter numerous difficulties in developing, manufacturing and marketing any new products resulting from a strategic alliance or acquisition that delay or prevent the Company from realizing their expected benefits or enhancing the Company’s business. The Company cannot assure you that, following any such acquisition, the Company will achieve the expected synergies to justify the transaction. In addition, the Company may require significant additional funds to either acquire such businesses or products or to commercialize them, which may result in significant dilution to shareholders or the incurrence of significant indebtedness by the Company.

We have traditionally relied on key collaborations and grants.

The development programs of the Company may require substantial additional cash. Traditionally, the Company has received funds under grant reward programs to fund portions of such development. The Company cannot provide assurance that it will continue to receive all or any of the grant funding that it applies for, that such grants if received will provide sufficient funding or that it will be able to establish future collaborations on commercially reasonable terms or at all. Inability to obtain grant funding and establish collaboration agreements may result in product development delays or cancellation, particularly in regard to pipeline programs. In addition, the success of collaboration agreements will depend heavily on the efforts and activities of the third-party collaborators, which are outside the control of the Company.

We are subject to evolving global laws and regulations relating to privacy, data protection and information security, which may require us to incur substantial compliance costs, and any failure or perceived failure by us to comply with such laws and regulations may harm our business and operations.

In the ordinary course of business, we process personal data and other sensitive information, including our proprietary and confidential business data, trade secrets, intellectual property, data about trial participants collected in connection with clinical trials, and other sensitive data. Our data processing activities subject us to numerous data privacy and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, contracts, and other obligations that govern the processing of personal data by us and on our behalf.

47

Table of Contents

In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, including data breach notification laws, personal data privacy laws, and consumer protection laws. For example, the U.S. federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH”), imposes specific requirements relating to the privacy, security, and transmission of individually identifiable health information. At the state level, the California Consumer Privacy Act of 2018 (“CCPA”), as amended and supplemented by the California Privacy Rights Act, imposes obligations on businesses to which it applies. The CCPA allows for statutory fines for noncompliance. Although the CCPA exempts some data processed in the context of clinical trials, the CCPA, to the extent applicable to our business and operations, may increase compliance costs and potential liability with respect to other personal information we may maintain about California residents. Other states have also enacted data privacy laws. Additional data privacy and security laws have been proposed at the federal, state, and local levels in recent years, which could further complicate compliance efforts.

Outside the U.S., the European Union’s general data protection regulation (“European Union GDPR”) and the United Kingdom’s general data protection regulation impose strict requirements for processing the personal data of individuals. For example, under the European Union GDPR, government regulators may impose temporary or definitive bans on data processing, as well as fines of up to 20 million euros or 4% of annual global revenue, whichever is greater. Further, individuals may initiate litigation related to our processing of their personal data. Certain foreign jurisdictions have enacted data localization laws and cross-border personal data transfer laws, which could make it more difficult to transfer information across jurisdictions, such as transferring or receiving personal data that originates in the EU.

Although we endeavor to comply with all applicable data privacy and security obligations, these obligations are quickly changing in an increasingly stringent fashion, creating some uncertainty as to how to comply, and potentially requiring us to modify our policies and practices, which may be costly and may divert the attention of management and technical personnel. Further, we may at times fail, or be perceived to have failed, to have complied and could face significant consequences. These consequences may include, but are not limited to, government enforcement actions, investigations and other proceedings; additional reporting requirements and/or oversight; bans on processing personal data; orders to destroy or not use personal data; and imprisonment of company officials. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: interruptions or stoppages in our business operations, including our clinical trials; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or revision or restructuring of our operations.

Our business and operations could suffer in the event of an actual or perceived information security incident such as a cybersecurity breach, system failure, or other compromise of our systems or those of a third-party or other contractor or vendor.

We rely on both internal information technology systems and networks, and those of third parties and their vendors and contractors, to transmit, store and otherwise process information in connection with our business activities. We are increasingly dependent upon our technology systems to operate our business and our ability to effectively manage our business depends on the security, reliability and adequacy of our and our third-party or other contractors’ or vendors’ technology systems and data. Any cyberattack including phishing, business email compromise, social engineering, ransomware or other malware, or any security breach, security incident, or other destruction, loss, or unauthorized use or other processing of data maintained or otherwise processed by us or on our behalf could result in a loss of intellectual property or misappropriation of trade secrets, disruptions to our business and operations, subject us to increased costs and require us to expend time and resources to address the matter, may subject us to claims, demands, and proceedings by private parties, regulatory investigations and other proceedings, and fines, penalties, and other liability and have a material adverse effect on our business. In addition, the loss, alteration or other damage to or other unavailability of pre-clinical data or clinical trial data from completed or ongoing clinical trials for our product candidates could result in delays in our development

48

Table of Contents

and regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Any cyber-attack, security breach or incident, or other destruction, loss or unauthorized processing of data maintained or otherwise processed by us or on our behalf, or the perception any such matter has occurred, could result in actual or alleged violations of applicable U.S. and international privacy, data protection, information security and other laws and regulations, harm our reputation and subject us to litigation and governmental investigations and proceedings by federal, state and local regulatory entities in the U.S. and by international regulatory entities, resulting in exposure to material civil and/or criminal proceedings and liability. In addition, we may incur significant additional expense to implement further measures relating to privacy, data protection and information security, whether in response to an actual or perceived security breach or incident or otherwise.

To date, we have not experienced any material impact to our business, financial position or operations resulting from cyberattacks or other information security incidents; however, because of frequently changing attack techniques, along with the increased volume and sophistication of such attacks, our business, financial position or operations could be adversely impacted in the future. Moreover, the prevalent use of mobile devices that access confidential information, widespread use of cloud-based applications with remote data centers, and ability to work remotely all increase the risk of security breaches and incidents. These risks may be heightened due to the increasing number of our and our vendors’ and contractors’ personnel working remotely. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate information security vulnerabilities. While we have implemented security measures, our computer systems and the external systems and services used by our third-party contract manufacturers and CROs and their vendors and contractors remain potentially vulnerable to these events and there can be no assurance that we will be successful in preventing cyber-attacks or successfully mitigating their effects. Our liability insurance may not be sufficient in type or amount to cover us against claims related to security breaches, cyberattacks and other related breaches. In addition, regulators are considering new cybersecurity regulations. These proposed regulations may impact the manner in which we operate.

We may fail to manage our growth successfully which may adversely impact our operating results.

The Company’s failure to manage its growth successfully may adversely impact its operating results. The Company’s ability to manage growth will require it to continue to build its operational, financial and management controls, contracting relationships, marketing and business development plans and controls and reporting systems and procedures. The Company’s ability to manage its growth will also depend in large part upon a number of factors, including the ability for it to rapidly:

• expand its internal and operational and financial controls significantly so that it can maintain control over operations;

• attract and retain qualified technical personnel in order to continue to develop its product candidates; and

• build commercial infrastructure following any approval of product candidates.

An inability to achieve any of these objectives could harm the business, financial condition and results of operations of the Company.

We rely on the protection of our intellectual property rights.

The Company’s commercial success depends to a significant degree upon its ability to develop new or improved technologies, instruments and products, and to obtain patents or other intellectual property rights or statutory protection for these technologies and products in Canada, the United States and other countries, such as the countries in the European Union and Asia. The Company intends to patent concepts, components, processes, industrial designs and methods, and other inventions and technologies that it considers to have commercial value or that will likely give it a competitive advantage. Despite devoting resources to the research and development of

49

Table of Contents

proprietary technology, the Company may not be able to develop new technology that is patentable or protectable. Further, patents issued to the Company, if any, could be challenged, held invalid or unenforceable, or be circumvented and may not provide the Company with necessary or sufficient protection or a competitive advantage.

In addition, despite its efforts to protect and maintain its patents, competitors and other third parties may be able to design around the Company’s patents, if so awarded, or develop products similar to its products that are not within the scope of such patents. Finally, patents provide certain statutory protection for a limited period of time that varies depending on the jurisdiction and type of patent. The statutory protection term of the Company’s material patents will expire at some time and thereafter the underlying technology of such patents will be allowed to be used by any third party, including its competitors. Moreover, the inventions covered by patents may be free to be used in countries for which there is no patent protection. A number of the Company’s competitors and other third parties have been issued patents, or may have filed patent applications, or may obtain additional patents or other intellectual property rights for technologies similar to those that the Company has developed, used or commercialized, or may develop, use or commercialize in the future. As certain patent applications in the United States and other countries are maintained in secrecy for a period of time after filing, and as publication or public awareness of new technologies often lags behind actual discoveries, the Company cannot be certain that it has been the first to develop the technology covered by its pending patent applications. In addition, the disclosure in its patent applications, including in respect of the utility of its claimed inventions, may not be sufficient to meet the statutory requirements for patentability in all cases. As a result, the Company cannot assure that its patent applications will result in valid or enforceable patents.

Prosecution and protection of the rights sought in patent applications and patents can be costly and uncertain, often involve complex legal and factual issues and consume significant time and resources. In addition, the breadth of claims allowed in the Company’s future patents, their enforceability and its ability to protect and maintain them cannot be predicted with any certainty. The laws of certain countries may not protect intellectual property rights to the same extent as the laws of Canada or the United States. Even if its patents are held to be valid and enforceable in a certain jurisdiction, any legal proceedings that the Company may initiate against third parties to enforce such patents will likely be expensive, take significant time and divert management’s attention from other business matters. The Company cannot assure that any of its pending patent applications will provide any protectable, maintainable or enforceable rights or competitive advantages to it.

In addition to patents, the Company relies on a combination of industrial designs, trademarks, trade secrets and other related laws and confidentiality procedures and contractual provisions to protect, maintain and enforce its proprietary technology and intellectual property rights in the United States, Canada and other countries. However, the Company’s ability to protect its brand by registering certain trademarks may be limited. In addition, while the Company generally enters into confidentiality and non-disclosure agreements with its employees, consultants and contractors to attempt to limit access to and distribution of its proprietary and confidential information, it is possible that:

• misappropriation of its proprietary and confidential information, including technology, will nevertheless occur;

• its confidentiality agreements will not be honored or may be rendered unenforceable;

• third parties will independently develop equivalent, superior or competitive technology or products;

• disputes will arise concerning the ownership, validity, enforceability, use patentability or registrability of intellectual property; or

• unauthorized disclosure of its know-how, trade secrets or other proprietary or confidential information will occur.

The Company cannot assure that it will be successful in protecting, maintaining or enforcing its intellectual property rights. If it is not successful in protecting, maintaining or enforcing its intellectual property rights, then the Company’s business, operating results and financial condition could be materially adversely affected.

We may not be able to enforce our intellectual property rights throughout the world.

The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of Canada and the United States. Many companies have encountered significant problems in protecting and defending intellectual property rights in certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favour the enforcement of patents and other intellectual property protection, especially those relating to life sciences. To the extent that the Company has obtained or is able to obtain patents or other intellectual property rights in any foreign jurisdictions, it may be difficult for the Company to stop the infringement of the Company’s patents or the misappropriation of other intellectual property rights. For example, some foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. In addition, many countries limit the availability of certain types of patent rights and enforceability of patents against third parties, including government agencies or government contractors. In these countries, patents may provide limited or no benefit.

Proceedings to enforce the Company’s patent rights in foreign jurisdictions could result in substantial costs and divert the Company’s efforts and attention from other aspects of the Company’s business. Accordingly, the Company’s efforts to protect the Company’s intellectual property rights in such countries may be inadequate.

Guidelines and recommendations published by various organizations can reduce the use of products that we may commercialize.

Government agencies promulgate regulations and guidelines directly applicable to us and to our product candidates and any future products. In addition, professional societies, such as the American College of Rheumatology, practice management groups, private health and science foundations and organizations involved in various diseases from time to time may also publish guidelines or recommendations to the healthcare and patient communities with respect to specific products. Recommendations of government agencies or these other groups or organizations may relate to such matters as usage, dosage, route of administration and use of concomitant therapies. Recommendations or guidelines that do not recognize the Company’s future products, suggest limitations or inadequacies of the Company’s future products, or suggest the use of competitive or alternative products as the standard of care to be followed by patients and healthcare providers, could result in decreased use or adoption of the Company’s future products.

Patent reform legislation in the United States could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

On September 16, 2011, the Leahy-Smith America Invents Act (the “Leahy-Smith Act”) was signed into law. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications will be prosecuted and may also affect patent litigation. In particular, under the Leahy-Smith Act, the United States transitioned in March 2013 to a “first to file” system in which the first inventor to file a patent application will be entitled to the patent. Third parties are allowed to submit prior art before the issuance of a patent by the United States Patent and Trademark Office (“USPTO”) and may become involved in post-grant proceedings including opposition, derivation, re-examination, inter partes review or interference proceedings challenging the Company’s patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope or enforceability of, or invalidate, the Company’s patent rights, which could adversely affect the Company’s competitive position.

The USPTO has developed regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act and in particular the first to file provisions, did not become effective until March 16, 2013. However, the full impact that the Leahy-Smith Act will have on the operation of the Company’s business is not clear. The Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of the Company’s patent applications and the enforcement or defense of the Company’s issued patents, as well as the Company’s ability to bring about timely favourable resolution of any disputes involving the Company’s patents and the patents of others.

51

Table of Contents

Non-compliance with regulatory requirements may reduce or eliminate our patent protection.

Periodic maintenance fees on any issued patent are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent. The USPTO and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which non-compliance can result in unenforceability, invalidity, abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in unenforceability, invalidity, abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If the Company or any future licensors fail to maintain the patents and patent applications covering the Company’s product candidates, the Company’s competitive position would be adversely affected.

We may infringe the intellectual property rights of others.

The Company’s commercial success depends, in part, upon it not infringing or violating intellectual property rights owned by others. The industry in which the Company competes has participants that own, or claim to own, intellectual property. The Company cannot determine with certainty whether any existing third-party patents, or the issuance of any new third-party patents, would require it to alter its technologies or products, obtain licenses or cease certain activities, including the sale of certain products.

The Company may in the future receive claims from third parties asserting infringement and other related claims. Litigation may be necessary to determine the scope, enforceability and validity of third-party intellectual property rights or to protect, maintain and enforce the Company’s intellectual property rights. Some of the Company’s competitors have, or are affiliated with companies having, substantially greater resources than it has, and these competitors may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than the Company can. Regardless of whether claims that it is infringing or violating patents or other intellectual property rights have any merit, those claims could:

• adversely affect the Company’s relationships with current or future counterparties;

• adversely affect its reputation with suppliers, payors or customers;

• be time-consuming and expensive to evaluate and defend;

• divert management’s attention and resources;

• subject the Company to significant liabilities and damages;

• require it to enter into royalty or licensing agreements; or

• require it to cease certain activities, including the sale of products.

If it is determined that the Company has infringed upon, violated or is infringing upon or violating a patent or the intellectual property right of any other person, or if it is found liable in respect of any other related claim, then in addition to being liable for potentially substantial damages, the Company may be prohibited from developing, using, distributing, selling or commercializing certain of its technologies and products unless it obtains a license from the holder of the patent or other intellectual property right. The Company cannot assure that it will be able to obtain any such license on a timely basis or on commercially favourable terms, or that any such licenses will be available, or that workarounds will be feasible and cost-efficient. If it does not obtain such a license or find a cost-efficient workaround, the Company’s business, operating results and financial condition could be materially adversely affected and it could be required to cease related business operations in some markets and restructure its business to focus on its continuing operations in other markets.

52

Table of Contents

We may be subject to claims arising from consultants or contractors misappropriating intellectual property.

Many of the Company’s consultants and contractors were previously or are concurrently employed at or engaged by biotechnology companies, and/or other pharmaceutical companies, including the Company’s competitors or potential competitors, or academic research institutions. Some of these consultants and contractors, including each member of the Company’s senior management or the Company’s other employees, may have executed proprietary rights, nondisclosure and non-competition agreements in connection with such previous or concurrent employment. The Company may be subject to claims that the Company or its consultants and contractors have used or disclosed the intellectual property and other proprietary information or know-how or trade secrets of others in their work for the Company. Litigation may be necessary to defend against these claims. The Company is not aware of any threatened or pending claims related to these matters or concerning agreements with the Company’s senior management, or other of the Company’s employees, consultants, and contractors, but litigation may be necessary in the future to defend against such claims. If the Company fails in defending any such claims, in addition to paying monetary damages, the Company may lose valuable intellectual property rights, or personnel or access to consultants and contractors. Even if the Company is successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while the Company’s policy is to require the Company’s consultants and contractors who may be involved in the development of intellectual property to execute agreements assigning such intellectual property to the Company, the Company may be unsuccessful in executing such an agreement with each party who in fact develops intellectual property that the Company regards as the Company’s own, which may result in claims by or against the Company related to the ownership of such intellectual property. If the Company fails in prosecuting or defending any such claims, in addition to paying monetary damages, the Company may lose valuable intellectual property rights. Even if the Company is successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to the Company’s management and scientific personnel.

We use hazardous chemicals and biological materials in our business. Any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.

Our product manufacturing, research and development, and testing activities involve the controlled use of hazardous materials, including chemicals and biological materials. We cannot eliminate the risks of accidental contamination or the accidental discharge of these materials, or any resulting injury from such an event. We may be subjected to litigation for any injury that results from our use or the use by third parties of these materials, and our liability may exceed our insurance coverage and our total assets. Our use, manufacture, storage, handling and disposal of these hazardous materials and specified waste products, as well as the discharge of pollutants into the environment and human health and safety matters, are governed by federal, state, provincial and local legislation. We are also subject to various laws and regulations relating to safe working conditions, laboratory and manufacturing practices. Our operations may require that environmental permits and approvals be issued by applicable government agencies, which can be costly and time-consuming to attain. These regulations and legislation can change, or new ones come into place, due to future legislative or administrative actions. These events could cause us to incur additional expense or restrict our operations. Compliance with environmental laws and regulations, current or future, may be expensive and prohibitive for our research, development, or production efforts. Failure to comply could incur substantial costs and liabilities, including civil or criminal fines and penalties, clean-up costs or capital expenditures to achieve and maintain compliance.

If product liability lawsuits are brought against us, then we may incur substantial liabilities and may be required to limit commercialization of EP-104IAR, if approved, and any other future products.

The Company faces a potential risk of product liability as a result of distribution of its product candidates for testing and commercialization of EP-104IAR and other pipeline products, if approved. For example, the Company may face claims if use of EP-104IAR allegedly causes injury or is found to be otherwise unsuitable

53

Table of Contents

during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in product quality, a failure to warn of dangers inherent in the product candidate or product, negligence, strict liability or a breach of warranties. Claims could also be asserted under state consumer protection acts. If the Company cannot successfully defend itself against product liability claims, the Company may incur substantial liabilities or be required to limit commercialization of the product subject to such claims. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

• decreased demand for any current and future approved product candidates;

• injury to the Company’s reputation;

• costs to defend any related litigation;

• diversion of management’s time and the Company’s resources;

• product recalls, withdrawals or labeling, marketing or promotional restrictions;

• loss of revenue;

• inability to commercialize EP-104IAR and other products, if approved;

• decline in the Company’s stock price; and

• exposure to adverse publicity.

Although the Company currently has product liability insurance in place, the Company does not know whether the limits of the insurance will be sufficient to satisfy any claims should they arise. We may not have sufficient resources to pay for any liabilities resulting from a claim excluded from or beyond the limits of, our insurance coverage. If we cannot successfully defend ourselves against a product liability claim, we may incur substantial liabilities.

Our employees, independent contractors, principal investigators, consultants, commercial partners and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading, which could significantly harm our business.

The Company is exposed to the risk that employees, independent contractors, principal investigators, consultants, commercial partners and vendors may engage in fraudulent or other illegal activity, fraud or other misconduct. Misconduct by these parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to the Company that violates: (i) the law and regulations of the FDA and non-US regulators, including those laws that require the reporting of true, complete and accurate information to the FDA and non-US regulators, (ii) healthcare fraud and abuse laws and regulations in the United States and elsewhere, and (iii) laws that require the true, complete and accurate reporting of financial information or data. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct in violation of these laws may also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to the Company’s reputation. It is not always possible to identify and deter misconduct by the Company’s executives, employees, consultants and other third parties, and any precautions the Company takes to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting the Company from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against the Company, and the Company is not successful in defending itself or asserting the Company’s rights, those actions could have a significant impact on the Company’s business, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in

54

Table of Contents

national healthcare programs, contractual damages, reputational harm, diminished profits and future earnings and curtailment of the Company’s operations, any of which could adversely affect the Company’s ability to operate the business and the Company’s results of operations.

We may be subject to securities litigation, which is expensive and could divert management attention.

The market price of the Common Shares may be volatile, and in the past companies that have experienced volatility in the market price of their shares have been subject to securities class action litigation. The Company may be the target of this type of litigation in the future. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could adversely impact the Company’s business. Any adverse determination in litigation could also subject the Company to significant liabilities.

We may be unable to adequately prevent disclosure of trade secrets and other proprietary information.

The Company relies on trade secrets to protect the Company’s proprietary technological advances and know-how, especially where the Company does not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. The Company relies in part on confidentiality agreements with the Company’s consultants, contractors, outside scientific collaborators, sponsored researchers and other advisors, including the third parties the Company relies on to manufacture the Company’s product candidates, to protect the Company’s trade secrets and other proprietary information. However, any party with whom the Company has executed such an agreement may breach that agreement and disclose the Company’s proprietary information, including the Company’s trade secrets. Accordingly, these agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Costly and time-consuming litigation could be necessary to enforce and determine the scope of the Company’s proprietary rights. In addition, others may independently discover the Company’s trade secrets and proprietary information. Failure to obtain or maintain trade secret protection could enable competitors to use the Company’s proprietary information to develop products that compete with the Company’s products or cause additional, material adverse effects upon the Company’s competitive business position and financial results.

Lawsuits relating to intellectual property infringement would be costly and time consuming.

The Company may be required to initiate litigation to enforce or defend the Company’s intellectual property rights. These lawsuits can be very time consuming and costly. There is a substantial amount of litigation involving patent and other intellectual property rights in the pharmaceutical industry generally. Such litigation or proceedings could substantially increase the Company’s operating expenses and reduce the resources available for development activities or any future sales, marketing or distribution activities.

In infringement litigation, any award of monetary damages the Company receives may not be commercially valuable. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of the Company’s confidential information and trade secrets could be compromised by disclosure during litigation. Moreover, there can be no assurance that the Company will have sufficient financial or other resources to file and pursue such infringement claims, which typically last for years before they are resolved. Further, any claims the Company asserts against a perceived infringer could provoke these parties to assert counterclaims against the Company alleging that the Company has infringed their patents. Some of the Company’s competitors may be able to sustain the costs of such litigation or proceedings more effectively than the Company can because of their greater financial resources. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on the Company’s ability to compete in the marketplace.

In addition, the Company’s patents and patent applications could face other challenges, such as interference proceedings, opposition proceedings, reissue, inter partes review, re-examination proceedings, third-party

55

Table of Contents

submissions of prior art, and other forms of post-grant review. Any of these challenges, if successful, could result in the invalidation of, or in a narrowing of the scope or preventing the issuance of, any of the Company’s patents and patent applications subject to challenge. Any of these challenges, regardless of their success, would likely be time consuming and expensive to defend and resolve and would divert the Company’s management and scientific personnel’s time and attention.

In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the market price of the Common Shares. Such litigation or proceedings could substantially increase the Company’s operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. The Company may not have sufficient financial or other resources to adequately conduct such litigation or proceedings.

Even if resolved in the Company’s favour, litigation or other legal proceedings relating to intellectual property claims may cause the Company to incur significant expenses and could distract the Company’s technical and management personnel from their normal responsibilities, which could have a material adverse effect on the Company’s financial position and results of operations.

Our directors and executive officers may be affiliated with other biotech companies and may have conflicts of interest.

Certain of the directors and executive officers of the Company may, from time to time, be employed by or affiliated with organizations which have entered into agreements or will enter into agreements with the Company. As disputes may arise between these organizations and the Company, or certain of these organizations may undertake or have undertaken research with the Company’s competitors, there exists the possibility for such persons to be in a position of conflict. The Company cannot assure that any decision or recommendation made by these persons involving the Company will be made in accordance with his or her duties and obligations to deal fairly and in good faith with the Company and such other organizations.

Our business may be affected by macroeconomic conditions.

Various macroeconomic factors could adversely affect the Company’s business and the results of the Company’s operations and financial condition, including changes in inflation, interest rates and foreign currency exchange rates, and overall economic conditions and uncertainties, including those resulting from political instability and the current and future conditions in the global financial markets. For instance, if inflation or other factors were to significantly increase the Company’s business costs, it may not be feasible to pass through price increases to patients. Interest rates, the liquidity of the credit markets and the volatility of the capital markets could also affect the value of the Company’s investments and the Company’s ability to liquidate the Company’s investments in order to fund the Company’s operations, if necessary.

Interest rates and the ability to access credit markets could also adversely affect the ability of payors and distributors to purchase, pay for and effectively distribute the Company’s products if and when approved. Similarly, these macroeconomic factors could affect the ability of the Company’s current or potential future contract manufacturers, sole-source or single-source suppliers, or licensees to remain in business or otherwise manufacture or supply the Company’s product candidates. Failure by any of them to remain in business could affect the Company’s ability to manufacture product candidates.

Our business may be affected by global geopolitical risks.

In addition to the risks specific to the countries in which the Company operates, global events such as war and occupation, terrorism and related geopolitical risks may lead to increased market volatility and may have adverse short-term and long-term effects on world economies and markets generally. For example, in late February 2022,

Russian military forces launched significant military action against Ukraine, and conflict and disruption in the region is ongoing. This conflict has the potential to affect our clinical trial operations in Poland, Czech Republic and Denmark. The impact to Ukraine, as well as actions taken by other countries, including new and stricter sanctions by Canada, the United Kingdom, the European Union, the United States and other countries and organizations against officials, individuals, regions, and industries in Russia, Ukraine and Belarus, and each country’s potential response to such sanctions, tensions, and military actions could have an adverse effect on the Company’s operations. These countries may impose further sanctions or other restrictive actions against governmental or other individuals or organizations in Russia or elsewhere. The effects of disruptive events could affect the global economy and financial and commodities markets in ways that cannot necessarily be foreseen at the present time. These events could also exacerbate other pre-existing political, social and economic risks, including those described elsewhere in this prospectus.

We may be responsible for corruption and anti-bribery law violations.

The Company’s business activities are subject to the to the United States Foreign Corrupt Practices Act (the “FCPA”) and other anti-bribery and anti-corruption laws of the United States and other countries in which the Company operates, as well as U.S. and certain foreign export controls and trade sanctions which generally prohibit companies and company employees from engaging in bribery or other prohibited payments to foreign officials for the purpose of obtaining or retaining business. The Company’s employees or other agents may, without its knowledge and despite its efforts, engage in prohibited conduct under the Company’s policies and procedures and the FCPA or other anti-bribery laws for which the Company may be held responsible. If the Company’s employees or other agents are found to have engaged in such practices, the Company could suffer severe penalties and other consequences that may have a material adverse effect on its business, financial condition and results of operations.

We are subject to foreign exchange risks.

As the Company grows and does business in foreign markets, including the United States and Europe, it is quite possible that transactions will take place in foreign currencies. At this point the Company does not participate in hedging activities. Although the Company cannot predict the effect of possible foreign exchange losses in the future, if such losses occurred, they could have a material adverse effect on the Company’s business, results of operation, and financial condition. In addition, fluctuations in exchange rates could affect the pricing of the Company’s products and negatively influence customer demand.

We are subject to taxation risks and changing rules by different tax authorities.

Tax examinations are often complex as tax authorities may disagree with the treatment of items reported by the Company, the result of which could have a material adverse effect on the Company’s financial condition and results of operations.

We are subject to a number of risks and hazards and may not be sufficiently insured for all of them.

The Company’s business is subject to a number of general risks and hazards, including general liability. Such occurrences could result in damage to property, inventory or facilities, personal injury or death to end-customers or operators, damage to the properties of the Company or the properties of others, monetary losses and possible legal liability. Although the Company maintains insurance to protect against certain risks in such amounts as it considers to be reasonable, its insurance may not cover all the potential risks associated with its operations. The Company may also be unable to maintain insurance to cover these risks at economically feasible premiums. Insurance coverage may not continue to be available or may not be adequate to cover any resulting liability. The Company might also become subject to liability which may not be insured against or which the Company may elect not to insure against because of premium costs or other reasons. Losses from these events may cause the Company to incur significant costs that could have a material adverse effect upon the Company’s financial performance and results of operations.

We will devote significant resources to regulatory compliance as a public entity.

As a public company, the Company incurs significant legal, accounting and other expenses. Legal, accounting and other expenses associated with public company reporting requirements have increased significantly in recent years. The Company anticipates that costs may continue to increase with corporate governance related requirements, including, without limitation, requirements under National Instrument 52-109—Certification of Disclosure in Issuers’ Annual and Interim Filings, National Instrument 52-110 - Audit Committees and National Instrument 58-101—Disclosure of Corporate Governance Practices.

The Company’s management and other personnel will devote a substantial amount of time to regulatory compliance initiatives. Moreover, these rules and regulations will increase the Company’s legal and financial compliance costs and make some activities more time-consuming and costly. For example, these rules and regulations may make it more difficult and more expensive for the Company to obtain director and officer liability insurance.

The Company’s testing, or any subsequent testing by the Company’s independent auditor, has in the past and may in the future reveal deficiencies in the Company’s internal control over financial reporting that are deemed to be material weaknesses. The Company will incur substantial accounting expense and expend significant management efforts to comply with internal control over financial reporting requirements. The Company currently does not have an internal audit group, and the Company anticipates hiring additional accounting and financial staff with appropriate public company experience and technical accounting knowledge. Moreover, if the Company is not able to comply with these requirements in a timely manner or if the Company or the Company’s independent auditor identifies deficiencies in the Company’s internal control over financial reporting that are deemed to be material weaknesses, the market price of the Common Shares could decline, and the Company could be subject to sanctions or investigations by applicable securities regulatory authorities, which would require additional financial and management resources.

In the past, we have had to restate our previously issued consolidated financial statements and as part of that process identified a material weakness in our disclosure controls and procedures and internal control over financial reporting as of December 31, 2022. If we are unable to develop and maintain effective disclosure controls and procedures and internal control over financial reporting, we may not be able to accurately report our financial results in a timely manner, which may adversely affect investor confidence in us and may adversely affect our business, financial condition and results of operations.

Under the supervision and with the participation of management, including our chief executive officer and chief financial officer, and in conjunction with the reaudit of our consolidated financial statements by our new auditor, KPMG LLP, we determined that there were a number of areas where our historical consolidated financial statements for the periods ending December 31, 2022 and 2021 required adjustment largely related to the accounting treatment of select financial instruments (notably convertible debt instruments and warrant valuations) and their classification as liabilities versus shareholders equity. As a result of this restatement, our management re-evaluated the effectiveness of our disclosure controls and procedures and internal control over financial reporting as of December 31, 2022. Management concluded that our disclosure controls and procedures were not effective as of December 31, 2022, and that our internal control over financial reporting was not effective as of December 31, 2022 due to a material weakness.

A material weakness is a deficiency, or a combination of deficiencies, in disclosure controls and procedures and internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Effective disclosure controls and procedures and internal control over financial reporting is necessary for us to provide reliable financial reporting and prevent fraud. Specifically, there was insufficient review of the classification of liabilities and equity under IAS 32 and the valuation of instruments in accordance with IFRS 13. We are working to remediate the material weakness, but we cannot be certain that we will be able to do so in a timely or efficient

58

Table of Contents

manner. Even if we are able to successfully remediate the material weakness, we may identify additional material weaknesses in the future.

As a company that intends to list securities in the United States, we will be required to comply with the requirements of the Exchange Act, Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and the listing standards of the Nasdaq Capital Market, including, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we will file with the SEC is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and that information required to be disclosed in reports under the Exchange Act is accumulated and communicated to our management, including our principal executive and financial officers.

We are also continuing to improve our internal control over financial reporting. Pursuant to the SEC rules that implement Section 404 of the Sarbanes-Oxley Act, beginning with our second annual report on Form 40-F after we become subject to the reporting requirements of the Exchange Act, we will be required to make a formal assessment of the effectiveness of our internal control over financial reporting. To achieve compliance with this requirement within the prescribed time period, we will be engaging in a process to document and evaluate our internal control over financial reporting under such rules, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of our internal control over financial reporting, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting. Despite our efforts, there is a risk that we will not be able to conclude, within the prescribed time period or at all, that our internal control over financial reporting is effective as required by Section 404 of the Sarbanes-Oxley Act. Moreover, our testing, or the subsequent testing by our independent registered public accounting firm, has in the past and may in the future reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses.

Any failure to implement and maintain effective disclosure controls and procedures and internal control over financial reporting, including the identification of one or more material weaknesses, could adversely impact our ability to report our financial condition and results of operations on a timely and accurate basis and could cause investors to lose confidence in the accuracy and completeness of our financial statements and reports, which would likely adversely affect the market price of our Common Shares. In addition, we could be subject to sanctions or investigations by Nasdaq, the SEC and other regulatory authorities. We also face potential for litigation or other disputes which may include, among others, claims invoking the securities laws, contractual claims or other claims arising from the restatement and the material weakness in our disclosure controls and procedures and internal control over financial reporting and the preparation of our financial statements. As of the date of this prospectus, we have no knowledge of any such litigation or dispute. However, we can provide no assurance that such litigation or dispute will not arise in the future. Any such litigation or dispute, whether successful or not, could adversely affect our business, financial condition and results of operations.

Risks Relating to Marketing, Reimbursement, Healthcare Regulations and Ongoing Regulatory Compliance

Coverage and reimbursement may be limited or unavailable in certain market segments for our product candidates, if approved, which could make it difficult for us to sell any product candidates or therapies profitably.

The success of our product candidates, if approved, depends on the availability of adequate coverage and reimbursement from third-party payors, including government agencies. There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. Coverage may be more limited than the purposes for which a therapeutic is approved by the FDA or comparable regulatory authorities in other jurisdictions.

59

Table of Contents

In the United States and some other jurisdictions, patients who are provided medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment. Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the United States, and commercial payors are critical to new product acceptance.

Government authorities and other third-party payors, such as private health insurers and health maintenance organizations, decide which drugs and treatments they will cover and the amount of reimbursement. In the United States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services (“CMS”) an agency within the U.S. Department of Health and Human Services (“HHS”). CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare, and private payors often follow CMS’ coverage decisions. Other jurisdictions have agencies, such as the National Institute for Health and Care Excellence in the UK, that evaluate the use and cost-effectiveness of therapies, which impact the utilization and price of the medicine in such jurisdiction.

In the United States, no uniform policy of coverage and reimbursement for products exists among third-party payors. As a result, obtaining coverage and reimbursement approval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our products on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate for us to maintain pricing sufficient to achieve or sustain profitability or may require co-payments that patients find unacceptably high.

We intend to seek approval to market our product candidates in different jurisdictions, which could include the United States, Canada and other selected foreign jurisdictions. If we obtain approval in any of these jurisdictions for our product candidates, we will be subject to rules and regulations in those jurisdictions. Market acceptance and sales of our product candidates will depend significantly on the availability of adequate coverage and reimbursement from third-party payors for our product candidates and may be affected by existing and future health care reform measures. Thus, even if favorable coverage and reimbursement status is attained for a product for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Our relationships with healthcare providers and physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States, Canada, and elsewhere play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our current and future arrangements with healthcare providers, third-party payors, customers, and others may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations. In particular, the research of our product candidates, as well as the promotion, sales and marketing of healthcare items and services and certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business or financial arrangements.

The applicable U.S. federal, state and other healthcare laws and regulations laws that may affect our ability to operate include, but are not limited to:

• the federal Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual, or the purchase, lease, order, arrangement,

60

Table of Contents

or recommendation of any good, facility, item or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person or entity can be found guilty of violating the statute without actual knowledge of the statute or specific intent to violate it. The term remuneration has been interpreted broadly to include anything of value. Further, courts have found that if “one purpose” of renumeration is to induce referrals, the federal Anti-Kickback Statute is violated. Violations are subject to significant civil and criminal fines and penalties for each violation, plus up to three times the remuneration involved, imprisonment, and exclusion from government healthcare programs. In addition, a claim submitted for payment to any federal healthcare program that includes items or services that were made as a result of a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act (“FCA”). The Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers, purchasers, and formulary managers, among others, on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution;

• the federal civil and criminal false claims laws, including the FCA, and civil monetary penalty laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, false, fictitious or fraudulent claims for payment to, or approval by Medicare, Medicaid, or other federal healthcare programs; knowingly making, using, or causing to be made or used, a false record or statement material to a false, fictitious or fraudulent claim or an obligation to pay or transmit money or property to the federal government; or knowingly concealing or knowingly and improperly avoiding, decreasing or concealing an obligation to pay money to the federal government. A claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim under the FCA. Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims. The FCA also permits a private individual acting as a “whistleblower” to bring qui tam actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery or settlement. When an entity is determined to have violated the FCA, the government may impose civil fines and penalties for each false claim, plus treble damages, and exclude the entity from participation in Medicare, Medicaid and other federal healthcare programs;

• HIPAA, which created additional federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or private), and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false, fictitious or fraudulent statement or representation, or making or using any false writing or document knowing the same to contain any materially false fictitious or fraudulent statement or entry in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters. Similar to the federal Anti-Kickback Statute, a person or entity can be found guilty of violating HIPAA fraud provisions without actual knowledge of the statute or specific intent to violate it;

• HIPAA, as amended by HITECH, and their respective implementing regulations, which impose, among other things, certain requirements relating to the privacy, security and transmission of individually identifiable health information on certain covered healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, as well as their respective “business associates,” those independent contractors or agents of covered entities that create, receive, maintain, transmit or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and their covered subcontractors, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to

61

Table of Contents

enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, there are additional federal, state and non-U.S. laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts;

• the federal Physician Payments Sunshine Act, created under the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the “ACA”), and its implementing regulations, which require manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to CMS information related to direct or indirect payments and other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), certain non-physician providers such as physician assistants and nurse practitioners, and teaching hospitals, as well as ownership and investment interests held by the physicians and their immediate family members.

• federal price reporting laws, which require manufacturers to calculate and report complex pricing metrics to government programs, where such reported prices may be used in the calculation of reimbursement and/or discounts on approved products;

• federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and

• analogous U.S. state, local and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers and may be broader in scope than their federal equivalents; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and other relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers and other potential referral sources, including the April 2003 Office of Inspector General Compliance Program Guidance for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America’s Code on Interactions with Healthcare Professionals; state and foreign laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures or drug pricing; state and local laws that require the registration of pharmaceutical sales representatives; and state and foreign laws governing the privacy and security of health information, some of which may be more stringent than those in the United States (such as the European Union, which adopted the General Data Protection Regulation, which became effective in May 2018) in certain circumstances, and may differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The scope and enforcement of each of the aforementioned laws are uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming, costly, and can divert a company’s attention from the business.

It is possible that governmental and enforcement authorities will conclude that our business practices, including our arrangements with physicians and other healthcare providers, may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If our

62

Table of Contents

operations are found to be in violation of any of the laws described above or any other government regulations that apply to us, we may be subject to significant sanctions, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, reputational harm, exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Further, if any of the physicians or other healthcare providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to similar penalties. Any action for violation of these laws, even if successfully defended, could cause a pharmaceutical manufacturer to incur significant legal expenses and divert management’s attention from the operation of the business. In addition, the approval and commercialization of any product candidate in other countries will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws. All of these could harm our ability to operate our business and our financial results.

Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs, suppliers and vendors may engage in misconduct or other improper activities. Misconduct by these parties could include failures to comply with FDA regulations, provide accurate information to the FDA, comply with federal and state health care fraud and abuse laws and regulations, accurately report financial information or data or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the health care industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct by these parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, integrity oversight and reporting obligations, contractual damages, reputational harm, diminished profits and future earnings and the curtailment or restructuring of our operations.

Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.

Certain laws and regulations require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted, delayed or become more expensive.

Ongoing healthcare legislative and regulatory reform measures may have a material adverse effect on our business and results of operations.

Changes in U.S., Canadian, and foreign regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements;

63

Table of Contents

(ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

In the United States and in some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative initiatives and regulatory changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare. For example, in March 2010, the ACA was enacted, which substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, expands the types of entities eligible for the 340B drug discount program; introduced a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations; established annual fees and taxes on manufacturers of certain branded prescription drugs; created a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; and provided incentives to programs that increase the federal government’s comparative effectiveness research.

Since its enactment, there have been numerous judicial, administrative, executive, and legislative challenges to certain aspects of the ACA, and we expect there will be additional challenges and amendments to the ACA in the future. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Other legislative changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011, which began in 2013 and, due to subsequent legislative amendments will remain in effect through 2032. Moreover, there has recently been heightened governmental scrutiny over the manner in which drug manufacturers set prices for their marketed products, which has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted, including:

• On January 2, 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

• On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.

• On May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try Act.

• On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020.

• On December 20, 2019, former President Trump signed into law the Further Consolidated Appropriations Act (H.R. 1865), which repealed the Cadillac tax, the health insurance provider tax, and the medical device excise tax. It is impossible to determine whether similar taxes could be instated in the future.

Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates than it receives on the sale of products, which could have a material impact on our business. In August 2022, Congress passed the Inflation Reduction Act of 2022 (the “IRA”), which includes prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal government to negotiate a maximum fair price for certain high-priced single source Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for beneficiaries, among other changes. The IRA permits the Secretary of HHS to implement many of these provisions through guidance, as opposed to regulation, for the initial years. HHS has and will continue to issue and update guidance as these programs are implemented, although the IRA may be subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. The IRA also extends enhanced subsidies for individuals purchasing health insurance coverage in ACA marketplaces through plan year 2025, and eliminates the “donut hole” under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and through a newly established manufacturer discount program. Further, in response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. The impact of these legislative, executive, and administrative actions and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is unclear. The implementation of cost containment measures, including the prescription drug provisions under the Inflation Reduction Act, as well as other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our product candidates if approved. Complying with any new legislation and regulatory changes could be time-intensive and expensive, resulting in a material adverse effect on our business.

These laws and regulations may result in additional reductions in Medicare and other healthcare funding and otherwise affect the prices we may obtain for any of our product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and biologic product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions on coverage or access could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates that we successfully commercialize or put pressure on our product pricing.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the extent to which state and federal governments cover particular healthcare products and services and could limit the amounts that the federal and state governments will pay for healthcare products and services. This could result in reduced demand for any product candidate we develop or could result in additional pricing pressures.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the United States. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

Risks Relating to our Securities

The market price of the Common Shares may be volatile.

The market price of the Common Shares may fluctuate due to a variety of factors relative to our business, including the following:

• announcements by us or our competitors of new products, product candidates or new uses for existing products, significant contracts, commercial relationships or capital commitments and the timing of these introductions or announcements;

• actions by any of our collaborators regarding our product candidates they are developing, including announcements regarding clinical or regulatory decisions or developments of our collaboration;

• unanticipated serious safety concerns related to the use of any of our products and product candidates;

• negative or inconclusive results from clinical trials of our product candidates, leading to a decision or requirement to conduct additional pre-clinical testing or clinical trials or resulting in a decision to terminate the continued development of a product candidate;

• delays of clinical trials of our product candidates;

• failure to obtain or delays in obtaining or maintaining product approvals or clearances from regulatory authorities;

• adverse regulatory or reimbursement announcements;

• announcements by us or our competitors of significant acquisitions, strategic collaborations, licenses, joint ventures or capital commitments;

• the results of our efforts to discover or develop additional product candidates;

• our dependence on third parties, including our collaborators, CROs, clinical trial sponsors and clinical investigators;

• regulatory or legal developments in Canada, the U.S. or other countries;

• developments or disputes concerning patent applications, issued patents or other proprietary rights;

• the recruitment or departure of key personnel;

• the level of expenses related to any of our product candidates or clinical development programs;

• actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts;

• actual or anticipated quarterly variations in our financial results or those of our competitors;

• sales of common shares by us, our insiders or our shareholders in the future, as well as the overall trading volume of the Common Shares;

• changes in the structure of healthcare payment systems;

• commencement of, or our involvement in, litigation;

• general economic, industry and market conditions;

66

Table of Contents

• market conditions in the pharmaceutical and biotechnology sectors and other factors that may be unrelated to our operating performance or the operating performance of our competitors, including changes in market valuations of similar companies; and

• the other factors described in this “Risk Factors” section.

The effect of these and other factors on the market price of the Common Shares on the TSX or any other exchange that we list securities on in the future, such as the Nasdaq Capital Market if the Common Shares are listed on such exchange, cannot be predicted. There can be no assurance that the market price of the Common Shares will not experience significant fluctuations in the future, including fluctuations that are unrelated to our performance.

Investors may lose their entire investment.

An investment in the Common Shares is speculative and may result in the loss of an investor’s entire investment in the Company. Only investors who are experienced in high-risk investments and who can afford to lose their entire investment should consider an investment in the Company.

We have no history of dividends.

To date, the Company has not paid any dividends on the outstanding Common Shares. We currently intend to retain future earnings to finance the operation, development and expansion of our business. We do not anticipate paying cash dividends on the Common Shares in the foreseeable future. Any decision to pay dividends on its shares will be made at the discretion of the Board and will depend on the Company’s earnings, financial requirements and other conditions existing at such time.

Our existing executive officers and directors own a significant percentage of Common Shares and may have a significant impact over matters submitted to the Company’s shareholders for approval.

The Company’s executive officers and directors own approximately 9.68% of the issued Common Shares as of September 30, 2023. As a result, these shareholders, if they acted together, could significantly impact all matters requiring approval by the Company’s shareholders, including the election of directors and the approval of mergers or other business combination transactions. The interests of these shareholders may not always coincide with the Company’s interests or the interests of other shareholders. This may also prevent or discourage unsolicited acquisition proposals or offers for the Common Shares that other shareholders may feel are in their best interest.

Future sales of Common Shares by our existing shareholders could cause the Company’s share price to decline.

Subject to compliance with applicable securities laws, the Company’s officers, directors and significant shareholders may sell some or all of their Common Shares in the future. No prediction can be made as to the effect, if any, such future sales of Common Shares will have on the market price of the Common Shares prevailing from time to time. However, the future sale of a substantial number of Common Shares by the Company’s officers, directors and significant shareholders or the perception that such sales could occur, could adversely affect prevailing market prices for the Common Shares.

We will need to raise additional financing in the future which may dilute our share capital.

The Company’s Articles permit the issuance of an unlimited number of Common Shares. Future issuance of Common Shares will result in dilution to the existing shareholders. Additionally, future sales of the Common Shares into the public market may lower the market price that may result in losses to the Company’s shareholders. The Company may, from time to time, issue stock options to purchase additional Common Shares

67

Table of Contents

in accordance with the policies of the TSX and, if applicable, the Nasdaq Capital Market. Most of these Common Shares, including the Common Shares to be issued upon exercise of options, are freely tradable or will be freely tradeable after a four-month restriction period. Sales of substantial amounts of the Common Shares into the public market, or even the perception by the market that such sales may occur, may lower the market price of Common Shares.

If securities or industry analysts either do not publish research about us or publish inaccurate or unfavorable research about us, our business or our market, or if they adversely change their recommendations regarding our Common Shares, the trading price or trading volume of our Common Shares could decline.

The trading market for Common Shares will be influenced in part by the research and reports that securities or industry analysts may publish about us, our business, our market or our competitors. If one or more securities analysts initiate research with an unfavorable rating or downgrade our Common Shares, provide a more favorable recommendation about our competitors or publish inaccurate or unfavorable research about our business, our Common Shares price would likely decline. If few securities analysts commence coverage of us, or if one or more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets and demand for our securities could decrease, which in turn could cause the price and trading volume of our Common Shares to decline.

DESCRIPTION OF DEBT SECURITIES

The following description of the terms of debt securities sets forth certain general terms and provisions of debt securities in respect of which a prospectus supplement may be filed. The particular terms and provisions of debt securities offered by any prospectus supplement, and the extent to which the general terms and provisions described below may apply thereto, will be described in the prospectus supplement filed in respect of such debt securities. Prospective investors should rely on information in the applicable prospectus supplement if it is different from the following information.

Debt securities may be offered separately or in combination with one or more other securities of the Company. The Company may, from time to time, issue debt securities and incur additional indebtedness other than through the issue of debt securities pursuant to this prospectus.

The debt securities will be issued under one or more indentures (each, a “Trust Indenture”), in each case between the Company and a financial institution or trust company organized under the laws of Canada or any province or territory thereof and authorized to carry on business as a trustee (each, a “Trustee”). Such indenture will be subject to and governed by the United States Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following description sets forth certain general terms and provisions of the debt securities and is not intended to be complete. The particular terms and provisions of the debt securities and a description of how the general terms and provisions described below may apply to the debt securities will be included in the applicable prospectus supplement. The following description is subject to the detailed provisions of the applicable Trust Indenture. Accordingly, reference should also be made to the applicable Trust Indenture, a copy of which will be filed by the Company with the securities commissions or similar regulatory authorities in applicable Canadian offering jurisdictions, after it has been entered into, and will be available electronically at www.sedarplus.ca and www.sec.gov/edgar.

General

The applicable Trust Indenture will not limit the aggregate principal amount of debt securities that may be issued under such Trust Indenture and will not limit the amount of other indebtedness that the Company may incur. The applicable Trust Indenture will provide that the Company may issue debt securities from time to time in one or more series and may be denominated and payable in U.S. dollars, Canadian dollars or any foreign currency. Unless otherwise indicated in the applicable prospectus supplement, the debt securities will be unsecured obligations of the Company.

The Company may specify a maximum aggregate principal amount for the debt securities of any series and, unless otherwise provided in the applicable prospectus supplement, a series of debt securities may be reopened for issuance of additional debt securities of such series. The applicable Trust Indenture will also permit the Company to increase the principal amount of any series of the debt securities previously issued and to issue that increased principal amount.

• the date or dates, or the methods by which such dates will be determined or extended, on which the Company may issue the debt securities and the date or dates, or the methods by which such dates will be determined or extended, on which the Company will pay the principal and any premium on the debt securities and the portion (if less than the principal amount) of debt securities to be payable upon a declaration of acceleration of maturity;

• whether the debt securities will bear interest, the interest rate (whether fixed or variable) or the method of determining the interest rate, the date from which interest will accrue, the dates on which the Company will pay interest and the record dates for interest payments, or the methods by which such dates will be determined or extended;

• the place or places the Company will pay principal, premium, if any, and interest, if any, and the place or places where debt securities can be presented for registration of transfer or exchange;

• whether and under what circumstances the Company will be required to pay any additional amounts for withholding or deduction for Canadian taxes with respect to the debt securities, and whether and on what terms the Company will have the option to redeem the debt securities rather than pay the additional amounts;

• whether the Company will be obligated to redeem or repurchase the debt securities pursuant to any sinking or purchase fund or other provisions, or at the option of a holder, and the terms and conditions of such redemption;

• whether the Company may redeem the debt securities at its option and the terms and conditions of any such redemption;

• the denominations in which the Company will issue any registered and unregistered debt securities;

• the currency or currency units for which debt securities may be purchased and the currency or currency units in which the principal and any interest is payable (in either case, if other than Canadian dollars) or if payments on the debt securities will be made by delivery of Common Shares or other property;

• whether payments on the debt securities will be payable with reference to any index or formula;

• if applicable, the ability of the Company to satisfy all or a portion of any redemption of the debt securities, any payment of any interest on such debt securities or any repayment of the principal owing upon the maturity of such debt securities through the issuance of securities of the Company or of any other entity, and any restriction(s) on the persons to whom such securities may be issued;

The Company reserves the right to include in a prospectus supplement specific terms pertaining to the debt securities which are not within the options and parameters set forth in this prospectus. In addition, to the extent that any particular terms of the debt securities described in a prospectus supplement differ from any of the terms described in this prospectus, the description of such terms set forth in this prospectus shall be deemed to have been superseded by the description of such differing terms set forth in such prospectus supplement with respect to such debt securities.

Unless stated otherwise in the applicable prospectus supplement, no holder of debt securities will have the right to require the Company to repurchase the debt securities and there will be no increase in the interest rate if the Company becomes involved in a highly leveraged transaction or has a change of control.

The Company may issue debt securities bearing no interest or interest at a rate below the prevailing market rate at the time of issuance, and offer and sell these debt securities at a discount below their stated principal amount. The Company may also sell any of the debt securities for a foreign currency or currency unit, and payments on the debt securities may be payable in a foreign currency or currency unit. In any of these cases, the Company will describe certain Canadian federal and U.S. federal income tax consequences and other special considerations in the applicable prospectus supplement.

Unless otherwise indicated in the applicable prospectus supplement, the Company may issue debt securities with terms different from those of debt securities previously issued and, without the consent of the holders thereof, reopen a previous issue of a series of debt securities and issue additional debt securities of such series.

Ranking and Other Indebtedness

Unless otherwise indicated in an applicable prospectus supplement, the debt securities will be direct unsecured obligations of the Company. The debt securities will be senior or subordinated indebtedness of the Company as described in the applicable prospectus supplement. If the debt securities are senior indebtedness, they will rank equally and ratably with all other unsecured indebtedness of the Company from time to time issued and outstanding which is not subordinated. If the debt securities are subordinated indebtedness, they will be subordinated to senior indebtedness of the Company as described in the applicable prospectus supplement, and they will rank equally and ratably with other subordinated indebtedness of the Company from time to time issued and outstanding as described in the applicable prospectus supplement. The Company reserves the right to specify in a prospectus supplement whether a particular series of subordinated debt securities is subordinated to any other series of subordinated debt securities.

The Board of Directors may establish the extent and manner, if any, to which payment on or in respect of a series of debt securities will be senior or will be subordinated to the prior payment of our other liabilities and obligations and whether the payment of principal, premium, if any, and interest, if any, will be guaranteed by any other person and the nature and priority of any security.

Registration of Debt Securities

Debt Securities in Book Entry Form

Unless otherwise indicated in an applicable prospectus supplement, debt securities of any series may be issued in whole or in part in the form of one or more global securities (“Global Securities”) registered in the name of a designated clearing agency (a “Depositary”) or its nominee and held by or on behalf of the Depositary in accordance with the terms of the applicable Trust Indenture. The specific terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a Global Security will, to the extent not described herein, be described in the prospectus supplement relating to such series. The Company anticipates that the provisions described in this section will apply to all depositary arrangements.

Upon the issuance of a Global Security, the Depositary or its nominee will credit, in its book-entry and registration system, the respective principal amounts of the debt securities represented by the Global Security to the accounts of such participants that have accounts with the Depositary or its nominee (“Participants”). Such accounts are typically designated by the underwriters, dealers or agents participating in the distribution of the debt securities or by the Company if such debt securities are offered and sold directly by the Company. Ownership of beneficial interests in a Global Security will be limited to Participants or persons that may hold beneficial interests through Participants. With respect to the interests of Participants, ownership of beneficial interests in a Global Security will be shown on, and the transfer of that ownership will be effected only through records maintained by the Depositary or its nominee. With respect to the interests of persons other than Participants, ownership of beneficial interests in a Global Security will be shown on, and the transfer of that ownership will be effected only through records maintained by Participants or persons that hold through Participants. The laws of some states in the United States may require that certain purchasers of securities take physical delivery of such securities in definitive form.

So long as the Depositary for a Global Security, or its nominee, is the registered owner of such Global Security, such Depositary or such nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by such Global Security for all purposes under the applicable Trust Indenture and payments of principal, premium, if any, and interest, if any, on the debt securities represented by a Global Security will be made by the Company to the Depositary or its nominee. The Company expects that the Depositary or its nominee, upon receipt of any payment of principal, premium, if any, or interest, if any, will credit Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the Global Security as shown on the records of such Depositary or its nominee. The Company also expects that payments by Participants to owners of beneficial interests in a Global Security held through such Participants will be governed by standing instructions and customary practices and will be the responsibility of such Participants.

Conveyance of notices and other communications by the Depositary to direct Participants, by direct Participants to indirect Participants and by direct and indirect Participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial owners of debt securities may wish to take certain steps to augment transmission to them of notices of significant events with respect to the debt securities, such as redemptions, tenders, defaults and proposed amendments to the Trust Indenture.

Owners of beneficial interests in a Global Security will not be entitled to have the debt securities represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of such debt securities in certificated non-book-entry form, and will not be considered the owners or holders thereof under the applicable Trust Indenture, and the ability of a holder to pledge a debt security or otherwise take action with respect to such holder’s interest in a debt security (other than through a Participant) may be limited due to the lack of a physical certificate.

No Global Security may be exchanged in whole or in part for debt securities registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any person other than the Depositary for

75

Table of Contents

such Global Security or any nominee of such Depositary unless: (i) the Depositary is no longer willing or able to discharge properly its responsibilities as depositary and the Company is unable to locate a qualified successor; (ii) the Company at its option elects, or is required by law, to terminate the book-entry system through the Depositary or the book-entry system ceases to exist; or (iii) if provided for in the Trust Indenture, after the occurrence of an event of default thereunder (provided the Trustee has not waived the event of default in accordance with the terms of the Trust Indenture), Participants acting on behalf of beneficial holders representing, in aggregate, a threshold percentage of the aggregate principal amount of the debt securities then outstanding advise the Depositary in writing that the continuation of a book-entry system through the Depositary is no longer in their best interest.

If one of the foregoing events occurs, such Global Security shall be exchanged for certificated non-book-entry debt securities of the same series in an aggregate principal amount equal to the principal amount of such Global Security and registered in such names and denominations as the Depositary may direct.

The Company, any underwriters, dealers or agents and any Trustee identified in an accompanying prospectus supplement, as applicable, will not have any liability or responsibility for (i) records maintained by the Depositary relating to beneficial ownership interests in the debt securities held by the Depositary or the book-entry accounts maintained by the Depositary, (ii) maintaining, supervising or reviewing any records relating to any such beneficial ownership interests, or (iii) any advice or representation made by or with respect to the Depositary and contained in this prospectus or in any prospectus supplement or Trust Indenture with respect to the rules and regulations of the Depositary or at the direction of Participants.

Unless otherwise stated in the applicable prospectus supplement, CDS Clearing and Depository Services Inc. or its successor will act as Depositary for any debt securities represented by a Global Security.

Debt Securities in Certificated Form

A series of the debt securities may be issued in definitive form, solely as registered securities, solely as unregistered securities or as both registered securities and unregistered securities. Unless otherwise indicated in the applicable prospectus supplement, unregistered securities will have interest coupons attached.

In the event that the debt securities are issued in certificated non-book-entry form, and unless otherwise indicated in the applicable prospectus supplement, payment of principal, premium, if any, and interest, if any, on the debt securities (other than a Global Security) will be made at the office or agency of the Trustee or, at the option of the Company, by the Company by way of cheque mailed or delivered to the address of the person entitled at the address appearing in the security register of the Trustee or electronic funds wire or other transmission to an account of the person entitled to receive such payments. Unless otherwise indicated in the applicable prospectus supplement, payment of interest, if any, will be made to the persons in whose name the debt securities are registered at the close of business on the day or days specified by the Company.

At the option of the holder of debt securities, registered securities of any series will be exchangeable for other registered securities of the same series, of any authorized denomination and of a like aggregate principal amount and tenor. If, but only if, provided in an applicable prospectus supplement, unregistered securities (with all unmatured coupons, except as provided below, and all matured coupons in default) of any series may be exchanged for registered securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. In such event, unregistered securities surrendered in a permitted exchange for registered securities between a regular record date or a special record date and the relevant date for payment of interest shall be surrendered without the coupon relating to such date for payment of interest, and interest will not be payable on such date for payment of interest in respect of the registered security issued in exchange for such unregistered security, but will be payable only to the holder of such coupon when due in accordance with the terms of the Trust Indenture. Unless otherwise specified in an applicable prospectus supplement, unregistered securities will not be issued in exchange for registered securities.

Table of Contents

The applicable prospectus supplement may indicate the places to register a transfer of the debt securities in definitive form. Except for certain restrictions to be set forth in the Trust Indenture, no service charge will be payable by the holder for any registration of transfer or exchange of the debt securities in definitive form, but the Company may, in certain instances, require a sum sufficient to cover any tax or other governmental charges payable in connection with these transactions.

DESCRIPTION OF WARRANTS

General

This section describes the general terms that will apply to any warrants for the purchase of Common Shares, or equity warrants, or for the purchase of debt securities, or debt warrants.

We may issue warrants independently or together with other Securities, and warrants sold with other Securities may be attached to or separate from the other Securities. Warrants will be issued under one or more warrant agency agreements to be entered into by us and one or more banks or trust companies acting as warrant agent.

The Company will deliver an undertaking to the securities regulatory authority in each of the provinces and territories of Canada that it will not distribute warrants that, according to their terms as described in the applicable prospectus supplement, are “novel” specified derivatives within the meaning of Canadian securities legislation, separately to any member of the public in Canada, unless the offering is in connection with and forms part of the consideration for an acquisition or merger transaction or unless such prospectus supplement containing the specific terms of the warrants to be distributed separately is first approved by or on behalf of the securities commissions or similar regulatory authorities in each of the provinces and territories of Canada where the warrants will be distributed.

This summary of some of the provisions of the warrants is not complete. The statements made in this prospectus relating to any warrant agreement and warrants to be issued under this prospectus are summaries of certain anticipated provisions thereof and do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all provisions of the applicable warrant agreement. You should refer to the warrant indenture or warrant agency agreement relating to the specific warrants being offered for the complete terms of the warrants. A copy of any warrant indenture or warrant agency agreement relating to an offering or warrants will be filed by the Company with the securities regulatory authorities in the applicable Canadian offering jurisdictions and the United States after we have entered into it, and will be available electronically on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov/edgar.

The applicable prospectus supplement relating to any warrants that we offer will describe the particular terms of those warrants and include specific terms relating to the offering.

Original purchasers of warrants (if offered separately) in Canada will have a contractual right of rescission against us in respect of the exercise of such warrant. The contractual right of rescission will entitle such original purchasers to receive, upon surrender of the underlying securities acquired upon exercise of the warrant, the total of the amount paid on original purchase of the warrant and the amount paid upon exercise, in the event that this prospectus (as supplemented or amended) contains a misrepresentation, provided that: (i) the exercise takes place within 180 days of the date of the purchase of the warrant under the applicable prospectus supplement; and (ii) the right of rescission is exercised within 180 days of the date of purchase of the warrant under the applicable prospectus supplement. This contractual right of rescission will be consistent with the statutory right of rescission described under section 131 of the Securities Act (British Columbia), and is in addition to any other right or remedy available to original purchasers under section 131 of the Securities Act (British Columbia) or otherwise at law.

In an offering of warrants, or other convertible securities, original purchasers are cautioned that the statutory right of action for damages for a misrepresentation contained in the prospectus is limited, in certain provincial and territorial securities legislation, to the price at which the warrants, or other convertible securities, are offered to the public under the prospectus offering. This means that, under the securities legislation of certain provinces and territories, if the purchaser pays additional amounts upon conversion, exchange or exercise of such securities, those amounts may not be recoverable under the statutory right of action for damages that applies in those provinces or territories. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for the particulars of these rights, or consult with a legal advisor.

Subscription receipts will be issued pursuant to one or more subscription receipt agreements (each, a “Subscription Receipt Agreement”), the material terms of which will be described in the applicable prospectus supplement, each to be entered into between the Company and an escrow agent (the “Escrow Agent”) that will be named in the relevant prospectus supplement. Each Escrow Agent will be a financial institution organized under the laws of Canada or a province or territory thereof and authorized to carry on business as a trustee. If underwriters or agents are used in the sale of any subscription receipts, one or more of such underwriters or agents may also be a party to the Subscription Receipt Agreement governing the subscription receipts sold to or through such underwriter or agent.

The following description sets forth certain general terms and provisions of subscription receipts that may be issued hereunder and is not intended to be complete. The statements made in this prospectus relating to any Subscription Receipt Agreement and subscription receipts to be issued thereunder are summaries of certain anticipated provisions thereof and are subject to, and are qualified in their entirety by reference to, all provisions of the applicable Subscription Receipt Agreement. Prospective investors should refer to the Subscription Receipt Agreement relating to the specific subscription receipts being offered for the complete terms of the subscription receipts.

PLAN OF DISTRIBUTION

New Issue

We may issue our Securities offered by this prospectus for cash or other consideration (i) to or through underwriters, dealers, placement agents or other intermediaries, (ii) directly to one or more purchasers, (iii) in connection with acquisitions of assets or shares or another entity or company or (iv) in connection with the exercise or conversion of Securities outstanding as of the date hereof, including, without limitation, outstanding warrants to purchase Common Shares. The consideration for an acquisition of assets or shares of another entity or company may consist of any of the Securities covered hereby separately, a combination of such Securities, or any combination of, among other things, Securities, cash or the assumption of liabilities.

The issuer has applied to list the Common Shares on the Nasdaq Capital Market. Listing will be subject to the Company fulfilling all of the listing requirements of the Nasdaq Capital Market and such listing may not occur or may be abandoned by the Company.

Each prospectus supplement with respect to our Securities being offered will set forth the terms of the offering, including:

• the name or names of any underwriters, dealers or other placement agents;

• the number and the purchase price of, and form of consideration for, our Securities;

• any proceeds to the Company from such sale; and

• any commissions, fees, discounts and other items constituting underwriters’, dealers’ or agents’ compensation.

Our Securities may be sold, from time to time, in one or more transactions at a fixed price or prices which may be changed or at market prices prevailing at the time of sale, at prices related to such prevailing prices or at negotiated prices, including sales in transactions that are deemed to be “at-the-market distributions” as defined in NI 44-102, including sales made directly on the TSX or other existing trading markets for the Securities. The prices at which the Securities may be offered may vary as between purchasers and during the period of distribution. If, in connection with the offering of Securities at a fixed price or prices, the underwriters have made a bona fide effort to sell all of the Securities at the initial offering price fixed in the applicable prospectus supplement, the public offering price may be decreased and thereafter further changed, from time to time, to an amount not greater than the initial offering price fixed in such prospectus supplement, in which case the compensation realized by the underwriters will be decreased by the amount that the aggregate price paid by purchasers for the Securities is less than the gross proceeds paid by the underwriters to the Company.

Only underwriters named in the prospectus supplement are deemed to be underwriters in connection with our Securities offered by that prospectus supplement.

Under agreements which may be entered into by the Company, underwriters, dealers and agents who participate in the distribution of our Securities may be entitled to indemnification by the Company against certain liabilities, including liabilities under the U.S. Securities Act and applicable Canadian securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. The underwriters, dealers and agents with whom we enter into agreements may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

Each class or series of preferred shares, debt securities, subscription receipts, warrants and units will be a new issue of Securities with no established trading market. Unless otherwise specified in the applicable prospectus supplement, the preferred shares, debt securities, warrants, subscription receipts or units will not be listed on any securities or stock exchange. Unless otherwise specified in the applicable prospectus supplement, there is no market through which the preferred shares, debt securities, warrants, subscription receipts or units may

86

Table of Contents

be sold and purchasers may not be able to resell preferred shares, debt securities, warrants, subscription receipts or units purchased under this prospectus or any prospectus supplement. This may affect the pricing of the preferred shares, debt securities, warrants, subscription receipts or units in the secondary market, the transparency and availability of trading prices, the liquidity of the securities, and the extent of issuer regulation. Subject to applicable laws, certain dealers may make a market in the preferred shares, debt securities, warrants, subscription receipts or units, as applicable, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any dealer will make a market in the preferred shares, debt securities, warrants, subscription receipts or units or as to the liquidity of the trading market, if any, for the preferred shares, debt securities, warrants, subscription receipts or units.

No underwriter or dealer involved in an “at-the-market” distribution, no affiliate of such underwriter or dealer and no person acting jointly or in concert with such underwriter or dealer has over-allotted, or will over allot, our securities in connection with an “at-the-market” distribution of our securities or effect any other transactions that are intended to stabilize the market price of our securities during an “at-the-market” distribution. In connection with any offering of Securities, except as otherwise set out in a prospectus supplement relating to a particular offering of Securities and other than in relation to an “at-the-market” distribution, the underwriters, dealers or agents, as the case may be, may over-allot or effect transactions intended to fix, stabilize, maintain or otherwise affect the market price of the Securities at a level other than those which otherwise might prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any time.

Secondary Offering

This prospectus may also, from time to time, relate to the offering of Securities by certain selling securityholders.

The selling securityholders may sell all or a portion of the Securities beneficially owned by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If Securities are sold through underwriters or broker-dealers, the selling securityholders will be responsible for underwriting discounts or commissions or agent’s commissions. Securities may be sold by the selling securityholders in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, as follows:

• on any national securities exchange or quotation service on which the Securities may be listed or quoted at the time of sale;

• in the over-the-counter market;

• in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

• through the writing of options, whether such options are listed on an options exchange or otherwise;

• ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

• block trades in which the broker-dealer will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

• privately negotiated transactions;

• an exchange distribution;

• short sales;

• broker-dealers may agree with the selling securityholders to sell a specified number of such shares at a stipulated price per share;

• a combination of any such methods of sale; and

• any other method permitted pursuant to applicable law.

87

Table of Contents

If the selling securityholders effect such transactions by selling the Securities to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling securityholders or commissions from purchasers of our Securities for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the Securities or otherwise, the selling securityholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the Securities in the course of hedging in positions they assume. The selling securityholders may also sell the Securities short and deliver the Securities covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling securityholders may also loan or pledge the Securities to broker-dealers that in turn may sell such shares.

As a foreign private issuer, we are exempt from the rules under the Exchange Act prescribing the furnishing and content of proxy statements, and our officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the Exchange Act. In addition, we are not required to publish financial statements as promptly as U.S. companies.

Table of Contents

You may read any document we file with or furnish to the securities commissions and authorities of the provinces and territories of Canada through SEDAR+ and any document we file with, or furnish to, the SEC on EDGAR, and may be accessed at www.sec.gov/edgar. Please note that the SEC’s website and the website containing Canadian securities regulatory filings are included in this prospectus and any applicable prospectus supplement as inactive textual references only. The information contained on such websites is not incorporated by reference in this prospectus and any applicable prospectus supplement and should not be considered part of this prospectus or any applicable prospectus supplement, except as explicitly described in the section titled “Documents Incorporated by Reference”.

AGENT FOR SERVICE OF PROCESS

Certain directors of the Company reside outside of Canada. As a result of the persons named below residing outside of Canada, each of them has appointed the following agent for service of process:

Name of Person or Company		Name and Address of Agent
Michael Wilmink		Blakes Vancouver Services Inc., c/o Blake, Cassels & Graydon LLP, located at Suite 3500, The Stack, 1133 Melville Street, Vancouver, British Columbia, V6E 4E5.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a company incorporated under the Business Corporations Act (British Columbia). Most of our directors and officers are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets may be, and a substantial portion of the Company’s assets are, located outside the United States. We have appointed an agent for service of process in the United States, but it may be difficult for holders of securities who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States. It may also be difficult for holders of securities who reside in the United States to realize in the United States upon judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors, officers and experts under the United States federal securities laws. We have been advised that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws or the securities or “blue sky” laws of any state within the United States, would likely be enforceable in Canada if the United States court in which the judgment was obtained has a basis for jurisdiction in the matter that would be recognized by a Canadian court for the same purposes. We have also been advised, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of the liability predicated solely upon U.S. federal securities laws.

We will file with the SEC, concurrently with our registration statement on Form F-10 of which this prospectus is a part, an appointment of agent for service of process on Form F-X. Under the Form F-X, we will appoint Corporation Service Company as our agent for service of process in the United States in connection with any investigation or administrative proceeding conducted by the SEC, and any civil suit or action brought against or involving us in a U.S. court arising out of or related to or concerning the offering of securities under this prospectus.
