PROSPECTUS SUPPLEMENT

TO THE SHORT FORM BASE SHELF PROSPECTUS DATED MAY 7, 2021

HEXO CORP.

Up to $150,000,000

COMMON SHARES

This prospectus supplement (the 'Prospectus Supplement'), together with the accompanying short form base shelf prospectus dated May 7, 2021 (the 'Shelf Prospectus'), as amended or supplemented, qualifies the distribution (the 'Offering') of common shares (the 'Offered Shares') of HEXO Corp. ('HEXO' or the 'Company'), having an aggregate sale price of up to $150,000,000 (or the equivalent in U.S. dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold). HEXO has entered into an equity distribution agreement dated May 11, 2021 (the 'Distribution Agreement') with A.G.P. / Alliance Global Partners and BMO Capital Markets Corp. (together, the 'U.S. Agents') and BMO Nesbitt Burns Inc. (the 'Canadian Agent', and together with the U.S. Agents, the 'Agents'), pursuant to which HEXO may distribute Offered Shares in the Offering from time to time through the Agents, as agents, in accordance with the terms of the Distribution Agreement. The Offered Shares offered under the Offering will also be registered in the United States under a registration statement on Form F-10(File No. 333-255264) (the 'Registration Statement') filed with the U.S. Securities and Exchange Commission (the 'SEC') under the U.S. Securities Act of 1933, as amended (the 'Securities Act'). See 'Plan of Distribution'.

Sales of Offered Shares, if any, under this Prospectus Supplement and the accompanying Shelf Prospectus are anticipated to be made in transactions that are deemed to be 'at-the-market distributions' as defined in National Instrument 44-102 - Shelf Distributions ('NI 44-102'), including sales made directly on the Toronto Stock Exchange (the 'TSX') or the New York Stock Exchange (the 'NYSE') or on any other trading market for the common shares of the Company (the 'Common Shares') in Canada or the United States. The Offered Shares will be distributed at the market prices prevailing at the time of the sale. As a result, prices at which Offered Shares are sold may vary as between purchasers and during the period of any distribution. There is no minimum amount of funds that must be raised under the Offering. This means that the Offering may terminate after raising only a portion of the offering amount set out above, or none at all. See 'Plan of Distribution'.

The outstanding Common Shares are listed on the TSX and the NYSE under the symbol 'HEXO'. On May 10, 2021, the closing prices of the Common Shares on such exchanges were $8.71 and US$7.22, respectively. The TSX has conditionally approved the listing of the Offered Shares, subject to the Company fulfilling all of the listing requirements of the TSX. The NYSE has approved the listing of the Offered Shares offered hereunder.

We will pay the Agents compensation for their services in acting as agents in connection with the sale of Offered Shares pursuant to the Distribution Agreement of up to 3.0% of the gross sales price per Offered Share sold (the

'Commission'). The Commission will be paid in the same currency in which the applicable Offered Shares were sold.

None of the Agents, nor any person or company acting jointly or in concert with any of the Agents, may, in connection with the distribution under the Offering, enter into any transaction that is intended to stabilize or maintain the price of the Offered Shares or the Common Shares, including selling an aggregate number of Offered Shares that would result in the Agent creating an over-allocation position in the securities. No underwriter or dealer involved in the distribution, no affiliate of such an underwriter or dealer and no person or company acting jointly or in concert with such an underwriter or dealer has over-allotted, or will over-allot, Common Shares in connection with the Offering or has effected, or will effect, any other transactions that are intended to stabilize or maintain the market price of the Common Shares.

Investing in the Offered Shares involves certain risks that should be carefully considered. See 'Risk Factors' in this Prospectus Supplement, 'Risk Factors' in the Shelf Prospectus, and the other documents incorporated by reference herein and therein.

The U.S. Agents will only sell Offered Shares on marketplaces in the United States and the Canadian Agent will only sell Offered Shares on marketplaces in Canada.

This Offering is being made by a Canadian issuer that is permitted, under the multi-jurisdictional disclosure system ('MJDS') adopted by the United States and Canada, to prepare this Prospectus Supplement in accordance with Canadian disclosure requirements. Purchasers of the Offered Shares should be aware that such requirements are different from those of the United States. We prepare our financial statements, which are incorporated by reference herein, in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board, and thus may not be comparable to the financial statements of United States issuers.

Purchasers of the Offered Shares should be aware that the acquisition, holding or disposition of the Offered Shares may have tax consequences both in the United States and in Canada. Such consequences for purchasers who are resident in, or citizens of, the United States or who are resident in Canada may not be described fully herein. Prospective investors should read the tax discussion under the headings 'Certain U.S. Federal Income Tax Considerations' and 'Certain Canadian Federal Income Tax Considerations' of this Prospectus Supplement and should consult their own tax advisors with respect to their own personal circumstances.

Your ability to enforce civil liabilities under U.S. federal securities laws may be affected adversely by the fact that we are incorporated under the laws of the Province of Ontario, Canada, all of our officers and directors and some of the experts named in this Prospectus Supplement and the Shelf Prospectus are non-U.S. residents, and that some or all or a substantial portion of the assets of the Company and such persons are located outside of the United States. See 'Enforceability of Civil Liabilities'.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY NOR HAS THE SEC OR ANY STATE OR CANADIAN SECURITIES COMMISSION OR REGULATORY AUTHORITY PASSED UPON THE ADEQUACY OR ACCURACY OF THIS PROSPECTUS SUPPLEMENT OR THE SHELF PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

The Company's head office is located at 3000 Solandt Road, Ottawa, Ontario, K2K 2X2. The Company's registered office is located at 1 First Canadian Place, 100 King Street West, Suite 6000, Toronto, Ontario, M5X 1E2.

Forward-looking statements contained in certain documents incorporated by reference in this Prospectus Supplement or the Shelf Prospectus are based on the key assumptions described in such documents. Certain of the forward-looking statements contained in this Prospectus Supplement, the Shelf Prospectus and the documents incorporated by reference herein and therein concerning the cannabis industry and the general expectations of HEXO concerning the cannabis industry and the Company's business and operations are based on estimates prepared by HEXO using data from publicly available governmental sources as well as from market research and industry analysis and on assumptions based on data and knowledge of the cannabis industry which HEXO believes to be reasonable. However, although generally indicative of relative market positions, market shares and performance characteristics, such data is inherently imprecise. While HEXO is not aware of any misstatement regarding any industry or government data presented herein or in the documents incorporated herein by reference, the cannabis industry involves risks and uncertainties and is subject to change based on various factors.

Forward-looking statements are subject to numerous risks and uncertainties, including those relating to the Company's ability to execute its business plan, renew required permits and licences and related regulatory compliance matters, the price at which Offered Shares are sold in the Offering and the aggregate net proceeds

received by the Company as a result of the Offering and other factors described under the heading 'Risk Factors' and elsewhere in this Prospectus Supplement, the Shelf Prospectus and the documents incorporated by reference herein and therein. A number of factors could cause actual events, performance or results to differ materially from what is projected in forward-looking statements.

Business of the Company

HEXO is in the business of producing, marketing and selling cannabis through its wholly-owned subsidiary, HEXO Operations Inc., which is a licensed producer under the Cannabis Regulations, from its facilities in Ontario and Québec, and is a leading branded cannabis producer and product innovator.

HEXO's near-term strategy is to be a vertically integrated consumer packaged goods ('CPG') company in the emerging legal adult-use and previously existing medical cannabis markets across Canada, with the intention to expand internationally where regulations allow. HEXO's primary business is to cultivate, process, package and distribute cannabis in order to serve these markets, which it currently does through (i) its 143-acre campus in Gatineau, Québec, which features 1,292,000 sq. ft. of greenhouse cultivation space and 10,000 sq. ft. of advanced automated manufacturing space, and (ii) its processing, manufacturing and distribution centre in Belleville, Ontario, which features 932,190 sq. ft. of commercial space and serves as the Company's main production facility for processing, extraction and packaging and the manufacture of cannabis derivative products.

The Company serves the legalized Canadian adult-use market through its HEXO, HEXO Plus, Up and Original Stash brands and the medical market through its HEXO brand. While the Company will continue to focus on branded cannabis products, it expects to develop its 'Powered by HEXO^®' strategy of introducing cannabinoids into consumer packaged goods, such as edibles, through partnerships with established CPG companies in Canada, the United States and globally.

HEXO's overall strategy is to establish a top global cannabis company with a leading market share in Canada through having strong standards of operational excellence, execution at scale, growing low-cost, high-quality cannabis, building targeted brands for all types of cannabis consumer segments and by partnering with large, established CPG companies to introduce Powered by HEXO^® products across their existing manufacturing and distribution infrastructure. HEXO is focused on building long-term sustainable shareholder value through consistent and profitable sales growth, careful management of selling, general and administrative expenses and maintaining a relatively low depreciable asset base and debt to equity ratio. The strategy is built upon three pillars: operational scalability, innovative products and brand leadership. In striving to achieve operational excellence, the Company's immediate focus remains on effective demand planning and production. The Company is continuously looking to implement more effective techniques to streamline operations, lower production costs, drive meaningful improvements in yields and improve inventory velocity; all as a part of the Company's renewed focus on profitability. The Company's innovation department is actively working towards developing modern, cutting edge cannabis products for the Canadian cannabis derivatives market. The Company plans to invest in even better, science-backed cannabis experiences and platform technology, as it continues to develop advanced ingredients formulations for use with its partners. The Company will continue to use its dominant position in Québec to strengthen distribution across the country with the Company's brands HEXO, HEXO Plus, Up, Original Stash and Bake Sale.

HEXO is centralizing its intellectual property and branding it 'Powered by HEXO^®' with the intention to partner with companies in different facets of the CPG market, enabling them to participate in the cannabis market beginning in Canada and subsequently around the world. Fundamentally, HEXO brings its brand value, cannabinoid isolation and delivery technology, licensed infrastructure and regulatory expertise to established companies, and in turn, HEXO plans to leverage the international distribution, base products and deep understanding of consumer markets of these partners.

Among its other activities, HEXO has entered into the Truss Limited Partnership joint venture with Molson Coors Canada to develop non-alcoholic, cannabis-infused beverages for the adult-use Canadian market. Truss Limited Partnership operates out of the Company's Belleville, Ontario facility. HEXO has also established the Keystone Isolation Technologies Inc. ('KIT') joint venture with Chroma Global Technologies Inc. to develop extraction,

S-6

refining and isolation technologies for cannabinoids found in both cannabis and hemp that is intended to enable HEXO to bring quality extracts to its partners. Through KIT, HEXO anticipates developing scalable capacity, potency and purity for distillates and isolates that will result in a consistent supply of CBD and THC for the Canadian and global market.

Following the passage of the U.S. Agricultural Improvement Act of 2018 (the '2018 Farm Bill'), the Company is actively working on expansion plans in the United States where and as permitted by applicable U.S. federal and state laws, including U.S. Food and Drug Administration requirements, to take advantage of opportunities in hemp-derived CBD products and markets. Through its wholly-owned subsidiary HEXO USA Inc., HEXO has entered into the Truss CBD USA joint venture with Molson Coors Beverage Company to develop non-alcoholic, hemp-derived CBD beverages in the State of Colorado. Truss CBD USA launched Veryvell^™, a new line of non-alcoholic, sparkling hemp-derived CBD beverages, exclusively available in the State of Colorado, in January 2021. Veryvell^™ is produced and distributed within Colorado state lines following the state's established regulatory framework for hemp-derived CBD in food and beverages and is exclusively distributed by Coors Distributing Company.

HEXO has also established the Keystone Isolation Technologies USA LLC ('KIT USA') joint venture with Chroma Global Technologies Inc. to leverage the technology developed by KIT for its U.S. expansion plans. KIT USA will allow for in state, HEXO controlled cannabis extraction activity to support the manufacturing of CBD beverages and future products in the U.S. In addition to its Truss CBD USA joint venture with Molson Coors Beverage Company in the State of Colorado, the Company is aiming to enter select U.S. states and to offer its 'Powered by HEXO^®' products to U.S. CBD markets via KIT USA and future partners, to the extent that such activities fully comply with applicable laws. The Company has recently appointed a general manager for its U.S. operations who is based in the U.S. and will be responsible for all implementation aspects of U.S. operations, starting in the State of Colorado, including stand up and commissioning of production facilities, overseeing operations, supply chain and logistics, and building the Company's U.S. team. The Company is currently seeking to acquire a facility in Colorado to use for its U.S. expansion plans, and that would be used by KIT USA in particular. The Company anticipates the acquisition costs and subsequent capital expenditures for retrofitting and improvement of this facility would cost approximately US$6.0 million and between US$16.5 million and US$49.5 million, respectively. The Company contemplates funding any acquisition costs through existing cash resources while capital expenditures for subsequent retrofitting and improvement would occur in stages over time and be funded through future financing activities.

HEXO only conducts business outside of Canada in jurisdictions where such activities are legally permissible in accordance with the laws of the applicable jurisdictions and the rules and policies of the TSX and the NYSE.

The Company is selectively seeking strategic acquisitions and commercial partnerships and is in various stages of negotiations and due diligence in respect of certain potential acquisition and joint venture, investment or other commercial partnership opportunities, including advanced stage negotiations and due diligence in respect of one possible acquisition. This particular acquisition would involve share consideration and would not be considered either a significant acquisition under the significance tests set out in Part 8 of National Instrument 51-102 -Continuous Disclosure Obligations ('NI 51-102') or a material acquisition as of the date of this Prospectus Supplement. There can be no assurance that any of these negotiations will result in acquisitions or joint ventures, investments or other commercial partnerships or, if they do, what the final terms or timing of such acquisitions or joint ventures, investments or other commercial partnerships would be. The Company expects to continue current negotiations and discussions and actively pursue other acquisition and joint venture, investment and other commercial partnership opportunities.

HEXO expects to require significant additional financing for its continued development, growth and currently contemplated or future business objectives and expansion plans, including additional anticipated contributions to its Truss Limited Partnership, Truss CBD USA, KIT and KIT USA joint ventures, contemplated U.S. expansion initiatives, potential additional expansion and improvements at its Belleville, Ontario production facility, and possible repayment of certain debts of Zenabis (as defined below) following the completion of the Zenabis Acquisition (as defined below).

Recent Developments

Share Consolidation

On December 17, 2020, the Company completed a consolidation of all of its issued and outstanding Common Shares on the basis of four (4) old Common Shares for one (1) new Common Share (the 'Share Consolidation'). As a result of the Share Consolidation, the Company's issued and outstanding Common Shares were reduced from 488,650,748 to approximately 122,162,687 (disregarding the treatment of any resulting fractional shares). In addition, the exercise or conversion price and the number of Common Shares issuable under the Company's outstanding common share purchase warrants, convertible debentures, stock options and other securities exercisable for or convertible into Common Shares were proportionately adjusted to reflect the Share Consolidation in accordance with the respective terms thereof.

The purpose of the Share Consolidation was to increase the trading price of the Common Shares and regain compliance with the NYSE's US$1.00 minimum share price continued listing standard (the 'NYSE Price Listing Standard'). HEXO had received notification from the NYSE on April 7, 2020 that it was no longer in compliance with the NYSE Price Listing Standard as a result of the average closing price of the Common Shares on the NYSE falling below US$1.00 for a consecutive 30 trading-day period. On January 4, 2021, HEXO received notification from NYSE that it has regained compliance post-Share Consolidation.

Acquisition of Zenabis Global Inc.

On February 16, 2021, HEXO entered into a definitive arrangement agreement (the 'Arrangement Agreement') with Zenabis Global Inc. ('Zenabis'), under which HEXO will acquire all of Zenabis' issued and outstanding common shares in an all-share transaction valued at approximately $235 million by way of court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the 'Zenabis Acquisition'). Under the terms of the Arrangement Agreement, Zenabis shareholders will receive 0.01772 of a Common Share in exchange for each Zenabis common share held (the 'Exchange Ratio'). Common share purchase warrants, incentive securities and convertible debt securities of Zenabis will be adjusted in accordance with their terms to ultimately become exercisable to receive Common Shares based on the Exchange Ratio. The Arrangement Agreement has been filed under the SEDAR profiles of HEXO and Zenabis on the SEDAR website at www.sedar.com.

Zenabis is a significant Canadian licensed cultivator of medical and recreational cannabis, which is a publicly listed company with its common shares listed for trading on the TSX. Zenabis employs staff coast-to-coast, across facilities in Atholville, New Brunswick; Langley, British Columbia; and Stellarton, Nova Scotia. Zenabis currently has 111,200 kg of licensed cannabis cultivation space across three licensed facilities in Canada, together with its cannabis import, export and processing joint venture, ZenPharm, operating from Birżebbuġa, Malta.

The Zenabis Acquisition needs to be approved by at least 66 2/3% of the votes cast by the shareholders of Zenabis present at a special meeting of Zenabis shareholders to be called by Zenabis to seek approval for the plan of arrangement to effect the Zenabis Acquisition. HEXO has entered into voting support agreements with Zenabis' directors and officers with respect to all Zenabis shares owned by them.

The Arrangement Agreement includes customary provisions, including non-solicitation provisions, subject to the right of Zenabis to accept a superior proposal in certain circumstances, with HEXO having a period of five business days to exercise a right to match any such superior proposal for Zenabis. The Arrangement Agreement also provides for a termination fee of $6.0 million payable by Zenabis to HEXO if the Zenabis Acquisition is terminated in certain specified circumstances, as well as reciprocal expense reimbursement fees if the Zenabis Acquisition is terminated by either party in certain other specified circumstances.

In addition to the approval by Zenabis' shareholders, the Zenabis Acquisition is subject to the receipt of certain regulatory, court and stock exchange approvals and the satisfaction of customary conditions precedent in transactions of this nature as well as the satisfaction of the following additional conditions precedent: (i) the termination and unconditional release of the guarantee provided by Zenabis in favour of Bank of Montreal in connection with the disposition of Bevo Farms Ltd. and its subsidiaries announced by Zenabis on January 4, 2021; (ii) the completion of

S-8

the Bevo Farms Ltd. sale transaction; and (iii) certain other specified conditions precedent set out in the Arrangement Agreement.

Upon completion of the Zenabis Acquisition, existing HEXO and Zenabis shareholders would respectively own approximately 88% and 12% of HEXO on a pro forma fully-diluted basis. In addition, HEXO has undertaken in the Arrangement Agreement, within 90 days of closing of the Zenabis Acquisition, to increase the size of its Board of Directors by one director and cause one of the current directors of Zenabis, selected by HEXO, to be appointed to the Board of Directors in accordance with HEXO's constating documents.

Contemporaneously with the signature of the Arrangement Agreement, Zenabis entered into an agreement with HEXO for the issuance of an unsecured convertible debenture to HEXO in the principal amount of $19.5 million, evidencing both a cash advance extended by HEXO to Zenabis at the end of 2020 as well as a further advance extended to Zenabis contemporaneously with the announcement of the Zenabis Acquisition for the purpose of allowing Zenabis to pay a settlement for a dispute between Zenabis and one of its customers. The unsecured convertible debenture bears interest at a rate of 8% per annum and matures on February 15, 2023. The debenture is convertible, in whole or in part, at any time after the earlier of the termination of the Arrangement Agreement and the then applicable 'Outside Date' thereunder, at the option of HEXO, into common shares of Zenabis at a conversion price equal to the 5-day VWAP of the common shares on TSX for the five trading days prior to the date of conversion. Zenabis has the right to prepay the debenture, at its option and without penalty or premium, at any time after the earlier of the termination of the Arrangement Agreement and the then applicable 'Outside Date' thereunder, subject to HEXO's right to elect to convert the debenture into Zenabis common shares prior to the prepayment. A change of control of Zenabis, other than the Zenabis Acquisition with HEXO, shall result in the mandatory conversion of the debenture into common shares of Zenabis at a conversion price equal to the 5-day VWAP where the last day of the 5-day VWAP of the common shares on TSX shall be the trading day immediately preceding the trading day on which the first of any such change of control transactions is initially publicly announced whether by Zenabis or by the person proposing, intending or agreeing to effect the change of control transaction. The unsecured convertible debenture also contains a provision that prevents HEXO from acquiring, at any given time as a result of and upon conversion of the debenture (other than in respect of a mandatory conversion in the context of a change of control transaction), more than 9.9% of Zenabis' common shares. The listing of the Zenabis common shares issuable pursuant to the conversion of the debenture is subject to the acceptance by the TSX.

Further information regarding the Zenabis Acquisition is included in the information circular that Zenabis has prepared, filed and mailed to its shareholders in connection with its special meeting to be held to consider and seek shareholder approval for the transaction. Zenabis has obtained an interim order from the British Columbia Supreme Court approving various procedural and related matters in order to convene the special meeting, and the special meeting is currently scheduled to be held on May 13, 2021.

The Zenabis Acquisition is not considered a significant probable acquisition under the significance tests set out in Part 8 of NI 51-102 as of the date of this Prospectus Supplement.

In connection with the Zenabis Acquisition, the Company expects to incur transaction and integration costs on a post-closing consolidated basis of approximately $15.0 million, including change of control payments and legal and other professional, consulting and finder fees. The Company also anticipates repaying certain debts of Zenabis post-closing. Plans for the debt repayments are not yet finalized but are anticipated to involve the repayment of debts in a total amount ranging from approximately $13.7 million to $125.0 million. The Company expects to fund these transaction and integration costs and repayment of certain amounts of the debts through existing cash resources. Additional debt repayments will depend on HEXO's integration plans for Zenabis and the availability of funds from future financing activities. A portion of the proceeds from the Offering will be used to replenish the Company's cash resources and working capital used to pay these transaction and integration costs and the minimum amount of debt repayments, and such proceeds may be used to satisfy additional debt repayments.

S-9

Repayment of Credit Facility

On April 30, 2021, the Company repaid the total outstanding balance on its credit facility established with certain Canadian Schedule 1 chartered banks in February 2019, together with accrued interest and associated fees, in the amount of approximately $28.9 million. The Company may obtain additional debt financing in the future.

RISK FACTORS

An investment in the Offered Shares is speculative and involves certain risks. Before making an investment in the Offered Shares, you should carefully consider the risks below and the risk factors described under the heading 'Risk Factors' in the accompanying Shelf Prospectus and the AIF, which are incorporated by reference in this Prospectus Supplement, as well as the risk factors described in the other documents incorporated by reference herein. See 'Documents Incorporated by Reference'. If any of these risks occur, the Company's business, results of operations, financial condition or prospects could be materially adversely affected. In that case, the trading price of our Common Shares could decline, and you may lose all or part of your investment. The risks set out in the documents indicated above are not the only risks we face. You should also refer to the other information set forth in this Prospectus Supplement, the Shelf Prospectus and the documents incorporated by reference herein and therein.

Risks Related to the Offering and the Offered Shares

Price Volatility of the Common Shares

The market price of the Common Shares may be volatile and subject to wide fluctuations in response to numerous factors, many of which are beyond HEXO's control. Companies in the cannabis sector, including HEXO, have also been experiencing extreme volatility in their trading prices. This volatility may affect the ability of holders of Common Shares to sell their securities at an advantageous price. Market price fluctuations in the Common Shares may be due to the Company's operating results failing to meet expectations of securities analysts or investors in any period, downward revision in securities analysts' estimates, adverse changes in general market or industry conditions or economic trends, acquisitions, dispositions or other material public announcements by the Company or its competitors, the COVID-19 pandemic, or a variety of other factors. These broad market fluctuations may adversely affect the trading price of the Common Shares.

Financial markets historically at times experienced significant price and volume fluctuations that have particularly affected the market prices of equity securities of companies and that have often been unrelated to the operating performance, underlying asset values or prospects of such companies. Accordingly, the market price of the Common Shares may decline even if the Company's operating results, underlying asset values or prospects have not changed. Additionally, these factors, as well as other related factors, may cause decreases in asset values that are deemed to be other than temporary, which may result in impairment losses. Continuing fluctuations in price and volume may occur. If such increased levels of volatility and market turmoil continue, the Company's operations could be adversely impacted and the trading price of the Common Shares may be materially and adversely affected.

Return on Investment Risk

There is no guarantee that an investment in the Offered Shares will earn any positive return in the short or long term. No dividends on the Common Shares have been paid to date. A purchase of Offered Shares under the Offering involves a high degree of risk and should be undertaken only by investors whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment.

Use of Net Proceeds from the Offering

Management currently expects to apply the net proceeds of the Offering as described under 'Use of Proceeds' of this Prospectus Supplement. However, management will have broad discretion with respect to the actual application of those net proceeds as well as the timing of their expenditures, and investors will be relying on the judgment of management regarding the application of these proceeds. You will not have the opportunity, as part of your investment in the Offered Shares, to evaluate any specific allocation of the net proceeds of the Offering or to influence the manner in which the net proceeds of the Offering are used. The failure by management to apply the net proceeds effectively

S-10

could have a material adverse effect on our business. There can be no assurance as to how the net proceeds will be allocated.

Future Sales or Issuances of Securities

We may issue additional securities to finance future activities outside of the Offering. The Company's articles permit the issuance of an unlimited number of Common Shares, and shareholders will have no pre-emptive rights in connection with such further issuances. The directors of the Company have discretion to determine the price and the terms of further issuances. Moreover, additional Common Shares will be issued by the Company on any exercise of options or other security-based compensation awards outstanding or issued by the Company, upon any exercise of outstanding common share purchase warrants, and upon any conversion or repayment in Common Shares of the principal amount of the Company's outstanding convertible debentures. We cannot predict the size of future issuances of securities or the effect, if any, that future issuances and sales of securities will have on the market price of the Common Shares. Sales or issuances of substantial numbers of Common Shares, or the perception that such sales could occur, may adversely affect prevailing market prices of the Common Shares. In connection with any issuance of Common Shares, investors will suffer dilution to their voting power and we may experience dilution in our earnings per share.

Dividends

HEXO has never declared or paid any dividends on the Common Shares. We intend, for the foreseeable future, to retain our future earnings, if any, to finance our business activities. The payment of future dividends, if any, will be reviewed periodically by our board of directors and will depend upon, among other things, conditions then existing including earnings, financial conditions, cash on hand, financial requirements to fund our business activities, development and growth, and other factors that our board of directors may consider appropriate in the circumstances. In addition, the Company is currently subject to contractual restrictions on the payment of dividends if any event of default under its outstanding unsecured convertible debentures occurs.

Risks Related to the Business

COVID-19

The outbreak of the novel coronavirus, or COVID-19, which was declared a pandemic by the World Health Organization in March 2020, has spread across the globe and is impacting economic activity worldwide. In response to the outbreak, governmental authorities in Canada and internationally have introduced various recommendations and measures to try to limit the pandemic, including travel restrictions, border closures, non-essential business closures, quarantines, self-isolations, shelters-in-place and social distancing. The COVID-19 pandemic and the response of governmental authorities to try to limit it have had, and continue to have, a significant impact on the private sector and individuals, including unprecedented business, employment and economic disruptions.

Since the outbreak of the pandemic, the Company has taken various steps to mitigate the impact of COVID-19, including implementing precautionary measures at its facilities to ensure the safety of its staff and product consumers. These measures include: the formation of a COVID-19 response team which is tasked to manage the Company's information flow of COVID-19 updates, review public health and safety protocols as outlined by the appropriate governmental authorities and develop in house action plans to mitigate these risks and comply accordingly; the transfer of all functions possible to work from home; for those functions which need to remain 'on site', the implementation of precautionary measures involving social distancing, full personal protective equipment such as gloves and masks, and additional personal sanitation stations throughout our manufacturing and administrative facilities; the implementation of travel restrictions for work-related travel where deemed unnecessary; restricted visitor access to our facilities; and initiation of a 'Hero Pay' program to support our cultivation and manufacturing employees who continue to work during the pandemic.

Fortunately, the Company's operations, results and financial position have not been materially impacted by COVID-19 related issues. We have not experienced material disruptions in our labour inputs and cultivation and processing activities, there have been no indicators of material issues to our supply chain, and on the consumer side, product demand has remained stable and cannabis retail has been declared an essential service across Canada and, as such, our

S-11

provincial distribution remains relatively unimpeded. While it remains uncertain as to whether COVID-19 will ultimately increase or diminish demand and sales of cannabis across Canada, we continue to work with provincial and private entities towards the goal of penetrating deeper into all markets and allow for the public to safely and reliably consume our products. We currently do not foresee any impact to supply to the market and, therefore, any impact on our cultivation, manufacturing and producing activities. However, despite these mitigation steps and the minimal impact on the Company's business to date, the continued presence and spread of COVID-19 nationally and globally could have a material adverse impact on our business, operations, financial results, position and prospects, including through disruptions in our cultivation and processing activities, supply chains and sales channels, and a reduction in supply of, or demand for, the Company's products.

Persistent social distancing measures and restrictions imposed by the federal, provincial and territorial governments in Canada on the movement of individuals and the distribution of cannabis in the country may adversely affect the Company's cannabis sales. It is difficult for the Company to predict how the COVID-19 pandemic may affect the Company's business in the future, including the effect it may have (positive or negative; long or short term) on the price of, and demand for, cannabis. It is possible that the COVID-19 pandemic could have a material adverse effect on the Company's business, financial condition, results of operations and prospects as well as the market for its securities and/or its ability to obtain financing. The extent to which the COVID-19 pandemic impacts the Company's results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the duration of the outbreak, the severity of the virus, and the actions taken to contain its impact.

In addition, COVID-19 is impacting cannabis retail sales channels and may adversely affect the Company's ability to successfully market and sell its products. While cannabis retail has been declared an essential service by provincial governments, with retailers continuing to operate with a mix of online and in-store sales and curbside pick-up and/or delivery services, and while licensed producers can continue production, the situation is uncertain. Moreover, sales volumes of cannabis may be adversely impacted by consumer 'social distancing' behaviours. What further impact, if any, the COVID-19 pandemic may have on cannabis retail markets is unpredictable. The COVID-19 pandemic may also negatively impact service levels with Health Canada, which licences and regulates the Company's operations. The continued spread of COVID-19 nationally and globally could also lead to a deterioration of general economic conditions including a possible national or global recession.

Due to the speed with which the COVID-19 situation is developing and the uncertainty of its magnitude, outcome and duration, it is not possible to estimate its impact on our business, operations or financial results; however, the impact could be material. The Company continues to monitor the situation and work with its stakeholders, including employees, customers and suppliers, in order to assess further possible implications to its business, supply chain and customers, and, where practicable, mitigate adverse consequences and responsibly address this global pandemic.

Cash Flow from Operations and Need for Additional Financing

The Company generated negative operating cash flow for the year ended July 31, 2020 and the six months ended January 31, 2021. The Company cannot guarantee that it will attain or maintain positive operating cash flow in the future. To the extent that the Company has negative cash flows in future periods, certain of the proceeds of any offering (including the Offering) may need to be allocated to funding this negative cash flow in addition to the Company's operational expenses or other activities. Moreover, HEXO may require additional financing to fund its operations to the point where it is generating positive cash flows, and continued negative cash flow may restrict HEXO's ability to pursue its business objectives.

As at April 30, 2021, and following the Company's repayment of the total outstanding balance on its credit facility, the Company had approximately $81.0 million in cash and approximately $240.0 million in working capital. The Company's existing cash and working capital are expected to provide sufficient liquidity to meet necessary cash outflow requirements for at least the next twelve months. If additional liquidity is required, management plans to secure the necessary financing through the issuance of new public or private equity or debt instruments. There is no assurance that additional future funding will be available to the Company, or that it will be available on terms which are acceptable to management.

S-12

HEXO expects, however, to require significant additional financing for its continued development, growth and its currently contemplated or future business objectives and expansion plans, including additional anticipated contributions to its Truss Limited Partnership, Truss CBD USA, KIT and KIT USA joint ventures, contemplated U.S. expansion initiatives, potential additional expansion and improvements at its Belleville, Ontario production facility, and possible repayment of Zenabis debts following the completion of the Zenabis Acquisition. The failure to raise such capital could result in the delay or indefinite postponement of all or any of the Company's currently contemplated or future business objectives and expansion plans and impede its continued development and growth. There can be no assurance that additional capital or other types of financing will be available if needed or that, if available, the terms of such financing will be favorable to HEXO. If additional funds are raised through 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 holders of Common Shares.

In addition, from time to time, HEXO may enter into transactions to acquire assets or the shares of other companies. These transactions may be financed wholly or partially with debt, which may temporarily increase HEXO's debt levels above industry standards. 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 HEXO to obtain additional capital and to pursue business opportunities, including potential acquisitions.

Risks Relating to the Zenabis Acquisition

There can be no assurance that the Company will complete the Zenabis Acquisition. The completion of the Zenabis Acquisition is subject to the satisfaction of a number of conditions which include, among others, obtaining necessary approvals, including approval of the shareholders of Zenabis, and the performance by Zenabis and HEXO of their respective obligations and covenants in the Arrangement Agreement, as well as key third-party conditions including the termination and unconditional release of the guarantee provided by Zenabis in favour of Bank of Montreal in connection with the disposition of Bevo Farms Ltd. and its subsidiaries announced by Zenabis on January 4, 2021 and the completion of the Bevo Farms Ltd. sale transaction.

The Zenabis Acquisition may not be completed, or may not be completed on the terms currently anticipated, as a result of a number of factors, including the failure of the parties to obtain necessary approvals or satisfy one or more of the conditions to closing. There can be no assurance the approvals will be obtained or the conditions to closing will be satisfied or waived, or that other events will not intervene to delay or result in the failure to close the Zenabis Acquisition. Delays in closing the Zenabis Acquisition or the failure to close the Zenabis Acquisition may result in the Company incurring additional costs in connection with such delay, termination of the Arrangement Agreement and/or the failure to achieve the anticipated benefits of the Zenabis Acquisition. Any delay in closing or a failure to close the Zenabis Acquisition could also have a negative impact on the Company's business and the trading price of the Common Shares. For instance, the Company could experience negative reactions from the financial markets, which could cause a decrease in the market price of the Common Shares, particularly if the market price reflects market assumptions that the Zenabis Acquisition will be completed or completed on certain terms. There could also be negative impact on the Company's ability to attract future acquisition opportunities.

The business and operations of Zenabis are outside HEXO's control until completion of the Zenabis Acquisition. Although the Arrangement Agreement contains certain covenants on the part of Zenabis regarding the operation of its business prior to closing the Zenabis Acquisition, the Company will not control Zenabis until the completion of the Zenabis Acquisition, and Zenabis' business and results of operations may be adversely affected by events that are outside of the Company's control during the interim period.

The historic and current performance of Zenabis' business and operations may not be indicative of its success in future periods, and the future performance of Zenabis' business may be influenced by, among other factors, general economic conditions, unfavorable regulatory decisions, litigation, the occurrence or discovery of new liabilities and other factors beyond our and Zenabis' control. As a result of any one or more of these factors, among others, the operations and financial performance of Zenabis may be negatively affected, which may adversely affect the future financial results of both Zenabis and the Company.

There can be no assurance that HEXO will be able to successfully integrate Zenabis with its business or otherwise realize the expected benefits of the Zenabis Acquisition. Achieving the potential benefits of the acquisition of Zenabis

S-13

will depend in part on HEXO's ability to successfully integrate the functions, operations, information technology and accounting systems and personnel of Zenabis in a timely and efficient manner, as well as on HEXO's ability to realize the anticipated growth opportunities and synergies, efficiencies and cost savings from integrating Zenabis with its business following completion of the Zenabis Acquisition. Special risks related to the Zenabis Acquisition and integration of Zenabis exist, including possible unanticipated costs and liabilities, unanticipated weaknesses in internal controls, diversion of management's attention and the loss of key employees or customers, as well as potential environmental liabilities in relation to one of Zenabis' facilities which have not yet been fully investigated or determined, if at all. A variety of factors, including the risk factors set forth in this Prospectus and the documents incorporated by reference herein, may also adversely affect the likelihood of the anticipated benefits of the acquisition.

Although the completion of the Zenabis Acquisition is not currently expected to have a material impact on HEXO's revenue or expenses in 2021, the Company has incurred, and expect to continue to incur, a number of costs associated with the completion of the Zenabis Acquisition, the integration of Zenabis into the Company's operations and achieving the desired synergies. HEXO will incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Other non-recurrent transaction costs related to the Zenabis Acquisition include, but are not limited to, fees paid to legal, financial and accounting advisors, as well as other related costs. HEXO continues to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the acquisition and integration of the two companies' businesses. In addition, even if successfully integrated, Zenabis' business may prove costly to operate and result in unexpected expenses and inefficiencies. Although HEXO expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow it to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all.

The completion of the Zenabis Acquisition and the integration of Zenabis into the Company's operations could cause the attention of the Company's management to be diverted from the day-to-day operations. These disruptions could be exacerbated by a delay in the completion of the Zenabis Acquisition and could have an adverse effect on the business, operating results or prospects of the Company regardless of whether the Zenabis Acquisition is ultimately completed.

The consideration payable by us in connection with the Zenabis Acquisition will be satisfied by the issuance of Common Shares based on the Exchange Ratio. In addition, in connection with the Zenabis Acquisition, the Company expects to incur transaction and integration costs on a post-closing consolidated basis of approximately $15.0 million, including change of control payments and legal and other professional, consulting and finder fees. The Company also anticipates repaying certain debts of Zenabis post-closing. Plans for the debt repayments are not yet finalized but are anticipated to involve the repayment of debts in a total amount ranging from approximately $13.7 million to $125.0 million. The Company expects to fund these transaction and integration costs and repayment of certain amounts of the debts through existing cash resources. Additional debt repayments will depend on HEXO's integration plans for Zenabis and the availability of funds from future financing activities. A portion of the proceeds from the Offering will be used to replenish the Company's cash resources and working capital used to pay these transaction and integration costs and the minimum amount of debt repayments, and such proceeds may be used to satisfy additional debt repayments. Consequently, holders of our Common Shares will incur dilution as a result of the Zenabis Acquisition.

Restrictions on U.S. Activities

HEXO only conducts business outside of Canada in jurisdictions where such activities are legally permissible in accordance with the laws of the applicable jurisdictions and the rules and policies of the TSX and the NYSE. Following the passage of the 2018 Farm Bill, the Company is actively working on expansion plans in the United States where and as permitted to take advantage of opportunities in hemp-derived CBD products and markets, such as the Truss CBD USA joint venture with Molson Coors Beverage Company in the State of Colorado and the establishment of KIT USA. The Company expects to use a portion of the proceeds from the Offering for these expansion plans.

The passage of the 2018 Farm Bill in December 2018 removed industrial hemp and hemp-derived products with a THC concentration of not more than 0.3% (dry weight basis) from Schedule I of the U.S. Controlled Substances Act (the 'CSA'). This has the effect of legalizing the cultivation of industrial hemp for commercial purposes, including the production of CBD and other cannabinoids, except for THC, subject to regulations to be developed by the U.S. Department of Agriculture. Despite cannabis having been legalized at the state level for medical use in many states

S-14

and for adult use in a number of states, cannabis containing 0.3% or more THC continues to be categorized as a Schedule I controlled substance under the CSA and subject to the U.S. Controlled Substances Import and Export Act (the 'CSIEA').

CBD is increasingly used as an ingredient in food and beverages, as an ingredient in dietary supplements and as an ingredient in cosmetics, thereby generating new investments and creating employment in the cultivation and processing of hemp and hemp-derived products. Foods and beverages, dietary supplements, pharmaceuticals, and cosmetics containing CBD are all subject to regulation under the U.S. Federal Food, Drug and Cosmetics Act (the 'FDCA'). The FDA has asserted that CBD is not a lawful ingredient in foods and beverages, supplements and pharmaceuticals (unless FDA-approved). As such, in the future if it decided to commercialize products containing CBD, and although the Company would work to maintain compliance with all applicable regulatory requirements, any potential FDA enforcement action against the Company could result in a number of negative consequences, including fines, disgorgement of profits, recalls or seizures of products, or a partial or total suspension of the Company's production or distribution of its products.

HEXO does not currently produce or distribute any cannabis products in the United States or accept payments from any party that does so. While HEXO is entering into the U.S. CBD market, it will do so in full compliance with the CSA, the CSIEA, the FCDA and all other applicable federal and state laws. Nonetheless, violations of any U.S. federal laws and regulations could result in significant fines, penalties, administrative sanctions, convictions or settlements arising from civil proceedings initiated by either the U.S. federal government or private citizens or criminal charges, including, but not limited to, disgorgement of profits, cessation of business and activities or divestiture.

HEXO's U.S. expansion plans are also subject to the rules of the TSX. On October 16, 2017, the TSX provided clarity regarding the application of Sections 306 (Minimum Listing Requirements) and 325 (Management) and Part VII (Halting of Trading, Suspension and Delisting of Securities) of the TSX Company Manual (collectively, the 'TSX Requirements') to applicants and TSX-listed issuers with business activities in the cannabis sector. In TSX Staff Notice 2017-0009, the TSX notes that issuers with ongoing business activities that violate U.S. federal law regarding cannabis are not in compliance with the TSX Requirements. These business activities may include (i) direct or indirect ownership of, or investment in, entities engaging in activities related to the cultivation, distribution or possession of cannabis in the U.S., (ii) commercial interests or arrangements with such entities, (iii) providing services or products specifically targeted to such entities, or (iv) commercial interests or arrangements with entities engaging in providing services or products to U.S. cannabis companies. The TSX reminded issuers that, among other things, should the TSX find that a listed issuer is engaging in activities contrary to the TSX Requirements, the TSX has the discretion to initiate a delisting review. Failure by the Company to comply with the requirements could have an adverse effect on its business.

HEXO does not engage in any U.S. cannabis-related activities as defined in Canadian Securities Administrators Staff Notice 51-352, and does not engage in any other activities involving cannabis or hemp with any level of THC or CBD in the United States except to the extent fully in compliance with U.S. federal law and all applicable state laws. We only conduct business in jurisdictions outside of Canada where such operations are legally permissible in accordance with all of the federal laws, and the state, provincial or similar laws, of the foreign jurisdiction, the federal, provincial and territorial laws of Canada and our regulatory obligations to the TSX. In addition, HEXO does not currently have any partnerships, joint ventures or similar arrangements with U.S.-based companies that may themselves participate in the U.S. cannabis market except in compliance with U.S. federal law and all applicable state laws.

Litigation

The Company may become party to litigation from time to time in the ordinary course of business which could adversely affect its business. Should any litigation in which the Company becomes involved be determined against the Company, such a decision could adversely affect the Company's ability to continue operating and the market price for the Common Shares and could use significant resources. Even if the Company is involved in litigation and wins, litigation can redirect significant company resources. While the Company cannot predict the outcome of any litigation that it is or may be involved in, it intends to assert all available defences and vigorously defend these proceedings. Defending litigation, whether or not meritorious, is time-consuming for management and detracts from the Company's ability to fully focus its internal resources on its business activities. In addition, legal fees and costs incurred in connection with such activities may be significant and the Company could, in the future, be subject to judgments or enter into settlements of claims for significant monetary damages. Further, the Company's Distribution Agreement with the Agents contains contractual indemnification provisions that may require the Company to indemnify the Agents with respect to the claims against them and their legal costs of defending the actions. A decision adverse to the Company's interests could result in the payment of substantial damages and could have a material adverse effect on our cash flow, results of operations and financial position, and the limits of available insurance may be insufficient to cover our eventual liability.

Investment Company Act Status

The U.S. Investment Company Act of 1940, as amended (the 'Investment Company Act'), prohibits a non-U.S. issuer that is an 'investment company' as defined therein from making public offers or sales of securities in the United States. An issuer generally will be deemed to be an 'investment company' for purposes of the Investment Company Act if it owns or proposes to acquire 'investment securities' having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis.

While we do not currently believe we are an 'investment company,' we hold assets that are investment securities, including our interests in Truss Limited Partnership and Truss CBD USA. We do not control the ability to restructure the Truss arrangement such that it is not an investment security. We also intend to enter into other joint ventures or

S-15

similar arrangements, which may involve investment securities. If the value of our interests in Truss Limited Partnership and Truss CBD USA, in other joint ventures or in other investment securities relative to our total assets were to increase, we may be deemed to be an investment company. In that case, we may not be able to raise additional funds through public offers and sales of securities in the United States and may otherwise have to substantially restrict or restructure our operations. We would not be able to avoid this outcome by registering as an investment company under the Investment Company Act because the Investment Company Act generally prohibits non-U.S. entities from registering and also imposes many restrictions on the capital structure, governance, and activities of registered investment companies, with which we would be unable to comply.

PFIC Status

Based upon the nature of the Company's current business activities, the Company does not believe it was a 'passive foreign investment company' ('PFIC') for U.S. income tax purposes for its 2020 fiscal year, and does not expect to be a PFIC in its current taxation year. However, the tests for determining PFIC status are based upon the composition of the income and assets of the Company and its subsidiaries and affiliates from time to time, and it is difficult to make accurate predictions of future income and assets. Accordingly, there can be no assurance that the Company will not become a PFIC in the future. A non-U.S. corporation generally will be considered a PFIC for any taxable year if either: (i) at least 75% of its gross income is passive income; or (ii) at least 50% of the value of its assets is attributable to assets that produce or are held for the production of passive income (which generally includes cash). If the Company were to be classified as a PFIC for any taxation year, such characterization could result in adverse U.S. income tax consequences to certain investors in the Company in the United States.

CONSOLIDATED CAPITALIZATION

There have been no changes in the consolidated capitalization of HEXO since January 31, 2021, the date of the Company's most recent financial statements, other than the following:

HEXO may, from time to time during the period that the Offering remains in effect, issue and sell Offered Shares having an aggregate sale price of up to $150,000,000 (or the equivalent in U.S. dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold). See 'Plan of Distribution'.

DESCRIPTION OF THE COMMON SHARES

We are authorized to issue an unlimited number of Common Shares, of which 122,465,534 Common Shares were issued and outstanding as of May 10, 2021. See 'Description of Securities - Common Shares' in the Shelf Prospectus for a description of the material attributes and characteristics of the Common Shares.

DIVIDEND POLICY

HEXO has never paid any dividends on the Common Shares. HEXO does not intend to pay any dividends on the Common Shares in the foreseeable future. In addition, HEXO is restricted from paying dividends pursuant to certain solvency tests prescribed under the Business Corporations Act (Ontario) and is currently subject to contractual restrictions on the payment of dividends if any event of default under its outstanding unsecured convertible debentures occurs. See 'Risk Factors'.

USE OF PROCEEDS

The net proceeds from the Offering are not determinable in light of the nature of the distribution. The net proceeds of any given distribution of Offered Shares through the Agents in an 'at-the-market distribution' will represent the gross proceeds after deducting the Commission, the expenses of the distribution and any transaction or filing fees imposed by any governmental, regulatory or self-regulatory organization in connection with the sales. The proceeds we receive

from sales will depend on the number of Offered Shares actually sold and the offering price of such Offered Shares. See 'Plan of Distribution'.

We intend to use the net proceeds from the Offering, if any, for general corporate purposes, which may include: (i) costs associated with the Company's U.S. expansion plans including the contemplated acquisition of a facility in the State of Colorado and its subsequent retrofitting and improvement; (ii) capital expenditures, including potential capital expenditures to make additional improvements to the production lines at the Company's Belleville, Ontario facility; (iii) potential future acquisitions; (iv) working capital, including replenishing existing cash resources and working capital used to pay certain transaction and integration costs and minimum debt repayments related to the Zenabis Acquisition; and (v) repayment of additional debts owed by Zenabis following the completion of the Zenabis Acquisition.

The allocation of the net proceeds will vary depending on future developments in the Company's business operations or unforeseen events, including those listed under the 'Risk Factors' section of this Prospectus Supplement. For example, the Company generated negative operating cash flow for the year ended July 31, 2020 and the six months ended January 31, 2021. The Company cannot guarantee that it will attain or maintain positive operating cash flow in the future. To the extent the Company has negative cash flows in future periods, certain of the proceeds of the Offering, if any, may be used to fund such negative operating cash flow in these periods. Our management will have broad discretion with respect to the use of the net proceeds from the sale of the Offered Shares, as well as the timing of their expenditure. See 'Risk Factors' in this Prospectus Supplement.

We may, from time to time, issue securities (including equity securities) other than pursuant to this Prospectus Supplement. See 'Risk Factors'.

PLAN OF DISTRIBUTION

We have entered into the Distribution Agreement with the Agents under which we may issue and sell from time to time Offered Shares having an aggregate sale price of up to $150,000,000 (or the equivalent in U.S. dollars determined using the daily exchange rate posted by the Bank of Canada on the date the Offered Shares are sold) in each of the provinces and territories of Canada and in the United States pursuant to placement notices delivered by us to the Agents from time to time in accordance with the terms of the Distribution Agreement. Sales of Offered Shares, if any, will be made in transactions that are deemed to be 'at-the-market distributions' as defined in NI 44-102, including sales made by the Agents directly on the TSX, the NYSE or any other trading market for the Common Shares in Canada or the United States or pursuant to any other sales method used by the Agents. Subject to the pricing parameters in a placement notice, the Offered Shares will be distributed at the market prices prevailing at the time of the sale. As a result, prices may vary as between purchasers and during the period of distribution. We cannot predict the number of Offered Shares that we may sell under the Distribution Agreement on the TSX, the NYSE or any other trading market for the Common Shares in Canada or the United States, or if any Offered Shares will be sold at all.

No minimum amount of funds must be raised under the Offering. This means that the Company could complete the Offering after raising only a small proportion of the Offering amount set out above, or none at all.

The Agents will offer the Offered Shares subject to the terms and conditions of the Distribution Agreement at such times as agreed upon by us and the Agents. In respect of any such offers, we will deliver a placement notice to the Agents or applicable Agent which will effect the sale of the Offered Shares, and will designate the number of Offered Shares to be sold in the placement notice. Subject to the terms and conditions of the Distribution Agreement, the Agents or applicable Agent will use their commercially reasonable efforts to sell, on our behalf, all of the Offered Shares requested to be sold by us. Under the Distribution Agreement, no Agent has any obligation to purchase as principal for its own account any Common Shares that we propose to sell pursuant to any placement notice delivered by us to the applicable Agent or Agents. If we sell the Offered Shares to one or more of the Agents as principal, we will enter into a separate agreement with such Agent or Agents and will describe that agreement in a separate prospectus supplement or free writing prospectus. Any such sale to the Agents as principal will require the approval of the TSX.

Either we or the Agents may suspend the Offering upon proper notice to the other party. We and each of the Agents have the right, by giving written notice as specified in the Distribution Agreement, to terminate the Distribution Agreement in each party's sole discretion at any time.

S-17

We will pay the Agents the Commission for their services in acting as agents in connection with the sale of Offered Shares pursuant to the Distribution Agreement. The amount of the Commission will be up to 3.0% of the gross sales price per Offered Share sold. The Commission will be paid in the same currency in which the applicable Offered Shares were sold. The sales proceeds remaining after payment of the Commission and after deducting any expenses payable by us and any transaction or filing fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal the net proceeds to us from the sale of such Common Shares.

The applicable Agent or Agents will provide written confirmation to us no later than the opening of the trading day immediately following the trading day on which it has made sales of the Offered Shares under the Distribution Agreement. Each confirmation will include the number of Offered Shares sold on such day (specifying the marketplace on which such Offered Shares were sold), the average price of the Offered Shares sold on such day, the gross proceeds, the Commission payable by us to the applicable Agent with respect to such sales and the net proceeds payable to us.

We will disclose the number and average price of the Offered Shares sold under this Prospectus Supplement, as well as the gross proceeds, Commission and net proceeds from sales hereunder in our annual and interim financial statements and related management's discussion and analysis filed on SEDAR and EDGAR for any quarters in which sales of Offered Shares occur pursuant to this Prospectus Supplement.

Settlement for sales of Offered Shares will occur, unless the parties agree otherwise, on the second trading day on the applicable exchange following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement. Sales of Offered Shares in the United States will be settled through the facilities of The Depository Trust Company or by such other means as we and the Agents may agree upon and sales of Offered Shares in Canada will be settled through the facilities of CDS Clearing and Depository Services Inc. or by such other means as we and the Agents may agree upon.

The U.S. Agents will only sell Offered Shares on marketplaces in the United States and the Canadian Agent will only sell Offered Shares on marketplaces in Canada.

In connection with the sales of the Offered Shares on our behalf, each of the Agents may be deemed to be an 'underwriter' within the meaning of the Securities Act, and the compensation paid to the Agents may be deemed to be underwriting commissions or discounts. We have agreed in the Distribution Agreement to provide indemnification and contribution to the Agents against certain liabilities, including liabilities under the Securities Act and Canadian securities laws. In addition, we have agreed to pay the reasonable expenses of the Agents in connection with the Offering, pursuant to the terms of the Distribution Agreement.

No underwriter of the at-the-market distribution, and no person or company acting jointly or in concert with an underwriter, may, in connection with the distribution, enter into any transaction that is intended to stabilize or maintain the price of the securities or securities of the same class as the securities distributed under the ATM prospectus, including selling an aggregate number or principal amount of securities that would result in the underwriter creating an over-allocation position in the securities.

The Agents and their affiliates have provided, and may in the future provide, various investment banking, commercial banking, fiduciary and advisory services for us from time to time for which they have received, and may in the future receive, customary fees and expenses. The Agents and their affiliates may, from time to time, engage in other transactions with and perform services for us in the ordinary course of their business. To the extent required by Regulation M under the United States Securities Exchange Act of 1934, as amended, the Agents will not engage in any market making activities involving the Common Shares while the Offering is ongoing under this Prospectus Supplement.

The total expenses related to the commencement of the Offering to be paid by us, excluding the Commission payable to the Agents under the Distribution Agreement, are estimated to be approximately $400,000.

Pursuant to the Distribution Agreement: (i) the Company has the right to terminate the Distribution Agreement with any or all of the Agents in its sole discretion at any time by giving written notice; (ii) each Agent has the right to terminate its obligations under the Distribution Agreement in its sole discretion at any time by giving written

S-18

notice; and (iii) the Distribution Agreement shall automatically terminate upon the earlier of (A) June 10, 2023; and (B) the issuance and sale of all the Offered Shares on the terms and subject to the conditions set forth in the Distribution Agreement.

The TSX has conditionally approved the listing of the Offered Shares, subject to the Company fulfilling all of the listing requirements of the TSX. In addition, the NYSE has approved the listing of the Offered Shares offered hereunder.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of DLA Piper (Canada) LLP, counsel to the Company, and Torys LLP, counsel to the Agents, the following is, as of the date of this Prospectus Supplement, a general summary of the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereunder (collectively, the 'Tax Act') generally applicable to an investor who acquires as beneficial owner Offered Shares pursuant to the Offering and who, for the purposes of the Tax Act and at all relevant times, (i) deals at arm's length with the Company and the Agents, (ii) is not affiliated with the Company or the Agents and (iii) acquires and holds the Offered Shares as capital property (a 'Holder'). Generally, the Offered Shares will be considered to be capital property to a Holder thereof provided that the Holder does not use the Offered Shares in the course of carrying on a business of trading or dealing in securities and such Holder has not acquired them in one or more transactions considered to be an adventure or concern in the nature of trade.

This summary does not apply to a Holder (i) that is a 'financial institution' for the 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 would be a 'tax shelter investment' as defined in the Tax Act, (iv) that has made a functional currency reporting election under the Tax Act to report in a currency other than the Canadian dollar, (v) that receives dividends on the Offered Shares under or as part of a 'dividend rental arrangement' as defined in the Tax Act, (vi) that has entered or will enter into a 'derivative forward agreement' or 'synthetic disposition arrangement', as each term is defined in the Tax Act, with respect to the Offered Shares, or (vii) that is exempt from tax under the Tax Act. Such Holders should consult their own tax advisors with respect to an investment in Offered Shares.

Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada, and that is or becomes, 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 event or series of transactions or events that includes the acquisition of the Offered Shares, controlled by a non-resident corporation (or pursuant to the Tax Proposals (as defined below) a non-resident person, or a group of non-resident persons (comprising any combination of non-resident corporations, non-resident individuals or non-resident trusts) not dealing with each other at arm's length for purposes of the Tax Act) for purposes of the 'foreign affiliate dumping' rules in section 212.3 of the Tax Act. Such Holders should consult their tax advisors with respect to the consequences of acquiring Offered Shares.

This summary is based upon the current provisions of the Tax Act in force as of the date hereof and counsel's understanding of the current published administrative policies and assessing practices of the Canada Revenue Agency (the 'CRA'). This summary takes into account all specific proposals to amend the Tax Act publicly 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 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 any changes in law or in the administrative policies or assessing practices of the CRA, whether by legislative, governmental or judicial decision or action, nor does it take into account or consider any provincial, territorial or foreign income tax considerations, which considerations may differ significantly from the Canadian federal income tax considerations discussed in this summary.

This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder. Holders should consult their own tax advisors with respect to their particular circumstances.

Residents of Canada

The following section of this summary applies to Holders who, for the purposes of the Tax Act, are or are deemed to be resident in Canada at all relevant times ('Resident Holders'). Certain Resident Holders whose Offered Shares might not constitute capital property may make, in certain circumstances, an irrevocable election permitted by subsection 39(4) of the Tax Act to deem the Offered Shares, and every other 'Canadian security' as defined in the Tax Act, held by such persons, in the taxation year of the election and each subsequent taxation year to be capital property. Resident Holders should consult their own tax advisors regarding this election.

Dividends

S-23

Dividends received or deemed to be received on the Offered Shares are required to be included in computing a Resident Holder's income. In the case of a Resident Holder that is an individual (other than certain trusts), such dividends will be subject to the gross-up and dividend tax credit rules normally applicable in respect of 'taxable dividends' received from 'taxable Canadian corporations' (each as defined in the Tax Act). An enhanced dividend tax credit will be available to individuals in respect of 'eligible dividends' designated by the Company to the Resident Holder in accordance with the provisions of the Tax Act. There may be limitations on the ability of the Company to designate dividends as eligible dividends.

Dividends received or deemed to be received by a corporation that is a Resident Holder on the Offered Shares are required to be included in computing its income but generally will be deductible in computing its taxable income, subject to all of the rules and restrictions under the Tax Act in that regard. 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 dispositions 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' (as defined in the Tax Act) or a corporation controlled by or for the benefit of an individual (other than a trust) or related group of individuals (other than trusts) generally will be liable to pay a refundable tax under Part IV of the Tax Act on dividends received or deemed to be received on the Offered Shares to the extent such dividends are deductible in computing the Resident Holder's taxable income for the year.

Dispositions of Offered Shares

Upon a disposition (or a deemed disposition) of an Offered Share (except to the Company, other than as a result of a purchase by the Company in the open market, if the Company acquired the Offered Share in the manner in which shares would normally be purchased by any member of the public in the open market), a Resident Holder generally will realize a capital gain (or a capital loss) equal to the amount, if any, by which the proceeds of disposition of such Offered Share, net of any reasonable costs of disposition, are greater (or are less) than the adjusted cost base of such Offered Share to the Resident Holder. The tax treatment of capital gains and capital losses is discussed in greater detail below under the subheading 'Capital Gains and Capital Losses'.

The adjusted cost base to a Resident Holder of an Offered Share acquired pursuant to the Offering will be averaged with the adjusted cost base of any other Common Shares held by such Resident Holder as capital property for the purposes of determining the Resident Holder's adjusted cost base of each Offered Share.

Capital Gains and Capital Losses

Generally, a Resident Holder is required to include in computing its income for a taxation year one-half of the amount of any capital gain (a 'taxable capital gain') realized in the year. Subject to and in accordance with the provisions of the Tax Act, a Resident Holder is required to deduct one-half of the amount of any capital loss (an 'allowable capital loss') realized in a taxation year from taxable capital gains realized in the year by such Resident Holder. Allowable capital losses in excess of taxable capital gains may be carried back and deducted in any of the three preceding taxation years or carried forward and deducted in any following taxation year against net taxable capital gains realized in such year to the extent and under the circumstances described in the Tax Act.

The amount of any capital loss realized on the disposition or deemed disposition of Offered Shares by a Resident Holder that is a corporation may be reduced by the amount of dividends received or deemed to have been received by it on such shares or shares substituted for such shares to the extent and under the circumstances described in the Tax Act. Similar rules may apply where a Resident Holder that is a corporation is a member of a partnership or beneficiary of a trust that owns such shares or that itself is a member of a partnership of a beneficiary of a trust that owns such shares. Resident Holders to whom these rules may be relevant should consult their own tax advisors.

A Resident Holder that is throughout the relevant taxation year a 'Canadian-controlled private corporation' (as defined in the Tax Act) may be liable to pay a refundable tax on its 'aggregate investment income' for the year, which will include taxable capital gains.

S-24

Minimum Tax

Capital gains realized and dividends received by a Resident Holder that is an individual (other than certain trusts) may give rise to minimum tax under the Tax Act. Resident Holders should consult their own advisors with respect to the application of minimum tax.

Non-Residents of Canada

The following section of this summary is generally applicable to Holders who at all relevant times for the purposes of the Tax Act (i) are not and are not deemed to be resident in Canada, and (ii) do not use or hold and are not deemed to use or hold the Offered Shares in carrying on a business in Canada ('Non-Resident Holders'). Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on an insurance business in Canada and elsewhere or that is an 'authorized foreign bank' (as defined in the Tax Act). Such Holders should consult their own tax advisors.

Dividends

Dividends paid or credited or deemed to be paid or credited on the Offered Shares to a Non-Resident Holder are subject to Canadian withholding tax at the rate of 25% of the gross amount of the dividend unless such rate is reduced by the terms of an applicable tax treaty. For example, under the Canada-United States Tax Convention (1980), as amended (the 'Treaty'), the rate of withholding tax on dividends paid or credited or deemed to be paid or credited to a Non-Resident Holder who is resident in the U.S. for purposes of the Treaty and entitled to benefits under the Treaty (a 'U.S. Holder') is generally limited to 15% of the gross amount of the dividend (or 5% in the case of a U.S. Holder that is a company that beneficially owns at least 10% of the voting stock of the Company).

Dispositions of Offered Shares

A Non-Resident Holder generally will not be subject to tax under the Tax Act in respect of a capital gain realized on the disposition or deemed disposition of an Offered Share, nor will capital losses arising therefrom be recognized under the Tax Act, unless the Offered Share constitutes 'taxable Canadian property' to the Non-Resident Holder thereof for purposes of the Tax Act, and the gain is not exempt from tax pursuant to the terms of an applicable tax treaty.

Provided the Offered Shares are listed on a 'designated stock exchange' as defined in the Tax Act (which currently includes the TSX and the NYSE) at the time of disposition, the Offered Shares generally will 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 or deemed disposition of the Offered Shares: (i) 25% or more of the issued shares of any class or series of the share capital of the Corporation were owned by, or belonged to, one or any combination of (A) the Non-Resident Holder, (B) persons with whom the Non-Resident Holder did not deal at arm's length (within the meaning of the Tax Act), and (C) partnerships in which the Non-Resident Holder or a person referred to in (B) holds a membership interest directly or indirectly through one or more partnerships; and (ii) more than 50% of the fair market value of the Offered Shares was derived directly or indirectly from one or any combination of (A) real or immovable property situated in Canada, (B) 'Canadian resource property' (as defined in the Tax Act), (C) 'timber resource property' (as defined in the Tax Act), and (D) options in respect of, or interests in, or for civil law rights in, property described in any of (A) through (C) above, whether or not such property exists. Notwithstanding the foregoing, an Offered Share may also be deemed to be taxable Canadian property of a Non-Resident Holder for purposes of the Tax Act.

A Non-Resident Holder's capital gain (or capital loss) in respect of Offered Shares that constitute or are deemed to constitute taxable Canadian property of a Non-Resident Holder (and are not 'treaty-protected property' as defined in the Tax Act) will generally be computed in the manner described above under the subheading 'Residents of Canada - Dispositions of Offered Shares'.

Non-Resident Holders whose Offered Shares are taxable Canadian property should consult their own tax advisors.

S-25

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a general summary of certain material U.S. federal income tax considerations applicable to a U.S. Holder (as defined herein) arising from and relating to the acquisition, ownership, and disposition of Common Shares acquired pursuant to this Prospectus Supplement.

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 arising from and relating to the acquisition, ownership, and disposition of Common Shares. 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, without limitation, specific tax consequences to a U.S. Holder under an applicable income 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 U.S. Holder. This summary does not address the 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 Common Shares. In addition, except as specifically set forth below, this summary does not discuss applicable tax reporting requirements. Each prospective U.S. Holder should consult its own tax advisors regarding the U.S. federal, 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 Common Shares.

No legal opinion from U.S. 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 consequences of the acquisition, ownership, and disposition of Common Shares. 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 are based are subject to various interpretations, the IRS and the U.S. courts could disagree with one or more of the conclusions described in this summary.

Scope of this Summary

Authorities

This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the 'Code'), final, temporary, or proposed regulations thereunder ('Treasury Regulations'), published rulings of the IRS, published administrative positions of the IRS, the Treaty, and U.S. court decisions that are applicable, and, in each case, as in effect and available, as of the date of this document. Any of the authorities on which this summary is based could be 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.

U.S. Holders

For purposes of this summary, the term 'U.S. Holder' means a beneficial owner of Common Shares acquired pursuant to the Offering that is for U.S. federal income tax purposes:

U.S. Holders Subject to Special U.S. Federal Income Tax Rules Not Addressed

This summary does not address the U.S. federal income tax considerations applicable to U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders that: (a) are tax-exempt organizations, qualified retirement plans, individual retirement accounts, or other tax-deferred accounts; (b) are financial institutions, underwriters, insurance companies, real estate investment trusts, or regulated investment companies; (c) are broker-

S-26

dealers, dealers, or traders in securities or currencies that elect to apply a mark-to-market accounting method; (d) have a 'functional currency' other than the U.S. dollar; (e) own Common Shares as part of a straddle, hedging transaction, conversion transaction, constructive sale, or other arrangement involving more than one position; (f) acquire Common Shares in connection with the exercise of employee stock options or otherwise as compensation for services; (g) hold Common Shares other than as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment purposes); (h) are required to accelerate the recognition of any item of gross income with respect to Common Shares as a result of such income being recognized on an applicable financial statement; or (i) own, have owned or will own (directly, indirectly, or by attribution) 10% or more of the total combined voting power or value of the outstanding shares of the Company. This summary also does not address the U.S. federal income tax considerations applicable to U.S. Holders who are: (a) U.S. expatriates or former long-term residents of the U.S.; (b) persons that have been, are, or will be a resident or deemed to be a resident in Canada for purposes of the Tax Act; (c) persons that use or hold, will use or hold, or that are or will be deemed to use or hold Common Shares in connection with carrying on a business in Canada; (d) persons whose Common Shares constitute 'taxable Canadian property' under the Tax Act; or (e) persons that have a permanent establishment in Canada for the purposes of the Treaty and that use or hold Common Shares in connection with such permanent establishment. U.S. Holders that are subject to special provisions under the Code, including, but not limited to, U.S. Holders described immediately above, should consult their own tax advisors regarding the U.S. federal, 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 Common Shares.

If an entity or arrangement that is classified as a partnership (or other 'pass-through' entity) for U.S. federal income tax purposes holds Common Shares, the U.S. federal income tax consequences to such entity and the partners (or other owners) of such entity generally will depend on the activities of the entity and the status of such partners (or owners). This summary does not address the tax consequences to any such partner (or owner). Partners (or other owners) of entities or arrangements that are classified as partnerships or as 'pass-through' entities for U.S. federal income tax purposes should consult their own tax advisors regarding the U.S. federal income tax consequences arising from and relating to the acquisition, ownership, and disposition of Common Shares.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE PURCHASERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS THE STATE, LOCAL, AND NON-U.S. TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF COMMON SHARES.

Ownership and Disposition of Common Shares

The following discussion is subject in its entirety to the rules described below under the heading 'Passive Foreign Investment Company Rules'.

Taxation of Distributions

A U.S. Holder that receives a distribution, including a constructive distribution, with respect to a Common Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any foreign income tax withheld from such distribution) to the extent of the current or accumulated 'earnings and profits' of the Company, as computed for U.S. federal income tax purposes. To the extent that a distribution exceeds the current and accumulated 'earnings and profits' of the Company, such distribution will be treated first as a tax-free return of capital to the extent of a U.S. Holder's tax basis in the Common Shares and thereafter as gain from the sale or exchange of such Common Shares (see 'Sale or Other Taxable Disposition of Common Shares' below). However, the Company may not maintain the calculations of its earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder may have to assume that any distribution by the Company with respect to the Common Shares will constitute dividend income. Dividends received on Common Shares by corporate U.S. Holders generally will not be eligible for the 'dividends received deduction'. Subject to applicable limitations and provided the Company is eligible for the benefits of the Treaty or the Common Shares are readily tradable on a United States securities market, dividends paid by the Company to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to qualified dividends, provided certain holding period and other conditions are

S-27

satisfied, including that the Company not be classified as a PFIC in the tax year of distribution or in the preceding tax year.

For U.S. federal income tax purposes, U.S. Holders will be treated as having received the amount of any Canadian taxes withheld by the Company, and as then having paid over the withheld taxes to the Canadian taxing authorities. As a result of this rule, the amount of dividend income included in gross income for U.S. federal income tax purposes by a U.S. Holder with respect to a payment of dividends may be greater than the amount of cash actually received (or receivable) by the U.S. Holder from the Company with respect to the payment.

The dividend rules are complex, and each U.S. Holder should consult its own tax advisors regarding the application of such rules.

Sale or Other Taxable Disposition of Common Shares

A U.S. Holder will recognize gain or loss on the sale or other taxable disposition of Common Shares in an amount equal to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. Holder's tax basis in such Common Shares sold or otherwise disposed of. Any such gain or loss generally will be capital gain or loss, which will be long-term capital gain or loss if, at the time of the sale or other disposition, such Common Shares are held for more than one year. If the consideration a U.S. Holder receives for the Common Shares is not paid in U.S. dollars, the amount realized will be determined using the rules described under 'Additional Considerations-Use of Foreign Currency to Purchase Common Shares or Receipt of Foreign Currency.' A U.S. Holder's tax basis in its Common Shares generally will equal the U.S. dollar cost of such Common Shares. If a U.S. Holder uses foreign currency to purchase Common Shares, the cost of the Common Shares will be determined using the rules described under 'Additional Considerations-Use of Foreign Currency to Purchase Common Shares or Receipt of Foreign Currency.'

Preferential tax rates apply to long-term capital gains of a U.S. Holder that is an individual, estate, or trust. There are currently no preferential tax rates for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations under the Code.

Passive Foreign Investment Company Rules

If the Company were to constitute a PFIC for any year during a U.S. Holder's holding period, then certain potentially adverse rules would affect the U.S. federal income tax consequences to a U.S. Holder resulting from the acquisition, ownership and disposition of Common Shares.

The Company generally will be a PFIC if, after the application of certain 'look-through' rules with respect to subsidiaries in which the Company holds at least 25% of the value of such subsidiary, for a tax year, (a) 75% or more of the gross income of the Company for such tax year is passive income or (b) 50% or more of the value of the Company's 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. 'Gross income' generally includes all 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.

The Company believes that it was not a PFIC for the fiscal year ended July 31, 2020, and based on current business plans and financial expectations, the Company expects that it should not be a PFIC for the current fiscal year and expects that it should not be a PFIC for the foreseeable future. No opinion of legal counsel or ruling from the IRS concerning the status of the Company as a PFIC has been obtained or is currently planned to be requested. However, PFIC classification is fundamentally factual in nature, generally cannot be determined until the close of the tax year in question, and is determined annually. Additionally, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. Consequently, there can be no assurance

that the Company has never been and will not become a PFIC for any tax year during which U.S. Holders hold Common Shares.

If the Company is a PFIC for any taxable year during which a U.S. Holder held Common Shares, the Company generally will continue to be treated as a PFIC with respect to such U.S. Holder for all succeeding years during which it holds Common Shares, unless the Company ceases to be a PFIC and the U.S. Holder makes a 'deemed sale' election with respect to the Common Shares. If such election is made, the U.S. Holder will be deemed to have sold the Common Shares it holds at their fair market value on the last day of the last taxable year in which the Company qualified as a PFIC, and any gain from such deemed sale would be subject to the consequences described below. After the deemed sale election, the U.S. Holder's Common Shares with respect to which the deemed sale election was made will not be treated as shares in a PFIC unless the Company subsequently becomes a PFIC.

In any year in which the Company is 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 potential 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 annually.

If the Company were a PFIC in any tax year during which a U.S. Holder held Common Shares, such holder generally would be subject to special rules with respect to 'excess distributions' made by the Company on the Common Shares and with respect to gain from the disposition of Common Shares. An 'excess distribution' generally is defined as (a) the gain from disposition of the Common Shares, and (b) the excess of distributions with respect to the Common Shares received by a U.S. Holder in any tax year over 125% of the average annual distributions such U.S. Holder has received from the Company during the shorter of the three preceding tax years, or such U.S. Holder's holding period for the Common Shares. Generally, a U.S. Holder would be required to allocate any excess distribution or gain from the disposition of the Common Shares ratably over its holding period for the Common Shares. Such amounts allocated to the year of the disposition or excess distribution (or to years on such U.S. Holder's holding period for Common Shares that are prior to the first taxable year in which the Company became a PFIC) would be taxed as ordinary income, and amounts allocated to prior tax years would be taxed as ordinary income at the highest tax rate in effect for each such year and an interest charge at a rate applicable to underpayments of tax would apply. The tax liability for amounts allocated to taxable years prior to the year of disposition or excess distribution cannot be offset by any net operating losses for such years, and gains (but not losses) realized on the sale of the Common Shares cannot be treated as capital, even if the U.S. Holder holds the Common Shares as capital assets.

While there are U.S. federal income tax elections that sometimes can be made to mitigate these adverse tax consequences (including the 'QEF Election' under Section 1295 of the Code and the 'Mark-to-Market Election' under Section 1296 of the Code), such elections are available in limited circumstances and must be made in a timely manner.

A U.S. Holder of 'marketable stock' (as defined herein) in a PFIC may make a mark-to-market election for such stock to elect out of the tax treatment discussed above. If a U.S. Holder makes a mark-to-market election for the Common Shares, it will include in income for each year that the Company is treated as a PFIC with respect to the U.S. Holder an amount equal to the excess, if any, of the fair market value of the Common Shares as of the close of the U.S. Holder's taxable year over its adjusted basis in such Common Shares. The U.S. Holder will be allowed a deduction for the excess, if any, of the adjusted basis of the Common Shares over their fair market value as of the close of the taxable year. However, deductions will be allowable only to the extent of any net mark-to-market gains on the Common Shares included in the U.S. Holder's income for prior taxable years. Amounts included in a U.S. Holder's income under a mark-to-market election, as well as gain on the actual sale or other disposition of the Common Shares, will be treated as ordinary income. Ordinary loss treatment will also apply to the deductible portion of any mark-to-market loss on the Common Shares, as well as to any loss realized on the actual sale or disposition of the Common Shares, to the extent the amount of such loss does not exceed the net mark-to-market gains previously included for such Common Shares. A U.S. Holder's basis in the Common Shares will be adjusted to reflect any such income or loss amounts. If a U.S. Holder makes a mark-to-market election, any distributions the Company makes would generally be subject to the rules discussed under subheading 'Ownership and Disposition of Common Shares - Taxation of Distributions', except the lower rate applicable to qualified dividend income would not apply.

S-29

The mark-to-market election is available only for 'marketable stock,' which is stock that is regularly traded on a qualified exchange or other market, as defined in applicable Treasury Regulations. The TSX has conditionally approved the listing of the Offered Shares offered hereunder, subject to the Company fulfilling all of the listing requirements of the TSX. The NYSE has approved the listing of the Offered Shares offered hereunder. A 'qualified exchange' includes a national securities exchange that is registered with the SEC or the national market system established pursuant to section 11A of the Exchange Act, such as the NYSE, as well as a foreign exchange that is regulated by a government authority in the jurisdiction in which the exchange is located and in respect of which certain other requirements are met, such as the TSX. The Common Shares will be considered regularly traded during any calendar year during which they are traded, other than in de minimis quantities, on at least 15 days during each calendar quarter. Any trades that have as one of their principal purposes the meeting of this requirement will be disregarded. Because a mark-to-market election cannot be made for equity interests in any lower-tier PFICs the Company owns, a U.S. Holder may continue to be subject to the PFIC rules with respect to its indirect interest in any investments held by the Company that are treated as an equity interest in a PFIC for U.S. federal income tax purposes. Once made, the election cannot be revoked without the consent of the IRS unless the Common Shares cease to be marketable. If the Company is a PFIC for any year in which the U.S. Holder owns the Common Shares but before a mark-to-market election is made, the interest charge rules described above will apply to any mark-to-market gain recognized in the year the election is made. A U.S. Holder should consult its tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any lower-tier PFICs.

Alternatively, if a non-U.S. corporation is a PFIC, a U.S. Holder of Common Shares in that corporation generally may avoid taxation under the PFIC rules described above regarding excess distributions and recognized gains by making a QEF Election to include in income its share of the corporation's income on a current basis. A QEF Election will apply to the tax year for which such QEF Election is timely 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, the Company ceases to be a PFIC, the QEF Election will remain in effect (although it will not be applicable provided that such QEF Election is made by such holder in the first year in such holder's holding period in which the Company is PFIC) during those tax years in which the Company is not a PFIC. Accordingly, if the Company becomes 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 during any subsequent tax year in which the Company qualifies as a PFIC. However, a U.S. Holder may make a QEF Election with respect to its Common Shares only if the Company furnishes the U.S. Holder with certain tax information annually.

U.S. Holders should be aware that, for each tax year, if any, that the Company is a PFIC, the Company can provide no assurances that it will satisfy the record keeping requirements or make available to U.S. Holders the information such U.S. Holders require to make a QEF Election with respect to the Company or any subsidiary that also is classified as a PFIC. U.S. Holders should consult their own tax advisors regarding the potential application of the PFIC rules to the ownership and disposition of Common Shares, and the availability of certain U.S. tax elections under the PFIC rules.

Additional Considerations

Additional Tax on Passive Income

Certain individuals, estates and trusts whose income exceeds certain thresholds will be required to pay a 3.8% Medicare surtax on 'net investment income' including, among other things, dividends and net gain from disposition of property (other than property held in certain trades or businesses). Special rules apply to PFICs. U.S. Holders should consult their own tax advisors regarding the application, if any, of this tax on their ownership and disposition of Common Shares.

Use of Foreign Currency to Purchase Common Shares or Receipt of Foreign Currency in Respect of a Sale of Common Shares or a Distribution

A U.S. Holder's tax basis in its Common Shares generally will equal the U.S. dollar cost of such Common Shares. If a U.S. Holder uses foreign currency to purchase Common Shares, the cost of the Common Shares will be the U.S. dollar value of the foreign currency purchase price determined by reference to the spot rate of exchange on the date of purchase. However, if the Common Shares are treated as traded on an established securities market and the U.S.

S-30

Holder is either a cash basis taxpayer or an accrual basis taxpayer who has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), such U.S. Holder will determine the U.S. dollar value of the cost of such Common Shares by translating the amount paid at the spot rate of exchange on the settlement date of the purchase.

The amount of any distribution paid to a U.S. Holder in foreign currency, or on the sale, exchange or other taxable disposition of 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). However, in the case of sale, exchange, or other taxable disposition of Common Shares, if the Common Shares are treated as traded on an 'established securities market' and the U.S. Holder is either a cash basis taxpayer or an accrual basis taxpayer that has made a special election (which must be applied consistently from year to year and cannot be changed without the consent of the IRS), such U.S. Holder will determine the U.S. dollar value of the amount realized in a foreign currency by translating the amount received at the spot rate of exchange on the settlement date of the sale.

A U.S. Holder will have a basis in the foreign currency equal to its U.S. dollar value on the date of receipt. Any U.S. Holder who converts or otherwise disposes of the foreign currency after the date of receipt 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.

Foreign Tax Credit

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. 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 that is subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all foreign taxes paid (whether directly or through withholding) by a U.S. Holder during a year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. Holder's U.S. federal income tax liability that such U.S. Holder's 'foreign source' taxable income bears to such U.S. Holder's worldwide taxable income. In applying this limitation, a U.S. Holder's various items of income and deduction must be classified, under complex rules, as either 'foreign source' or 'U.S. source.' Generally, dividends paid by a foreign corporation should be treated as foreign source for this purpose, and gains recognized on the sale of stock of a foreign corporation by a U.S. Holder should be treated as U.S. source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, and subject to certain exceptions, a portion of the dividends paid by a foreign corporation will be treated as U.S. source income for U.S. foreign tax credit purposes, in proportion to its U.S. source earnings and profits, if U.S. persons own, directly or indirectly, 50% or more of the voting power or value of the foreign corporation's shares. In addition, the amount of a distribution with respect to the Common Shares that is treated as a 'dividend' may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition, this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and each U.S. Holder should consult its own U.S. tax advisor regarding the foreign tax credit rules.

Backup Withholding and Information Reporting

Under U.S. federal income tax law and Treasury Regulations, 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 individuals who are 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, any financial instrument or contract held for investment that has an issuer or counterparty other than a U.S. person and any interest in a foreign

S-31

entity. U.S. Holders may be subject to these reporting requirements unless their Common Shares are held in an account at certain financial institutions. Penalties for failure to file certain of these information returns are substantial. U.S. Holders should consult their own tax advisors regarding the requirements of filing information returns, including the requirement to file an IRS Form 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, Common Shares will generally be subject to information reporting and backup withholding tax, at the rate of 24%, if a U.S. Holder (a) fails to furnish such U.S. Holder's 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 such U.S. Holder 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 generally are excluded from these information reporting and backup withholding rules. Backup withholding is not an additional tax. 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 advisor 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 Common Shares. U.S. Holders should consult their own tax advisors as to the tax considerations applicable to them in their own particular circumstances.

ELIGIBILITY FOR INVESTMENT

In the opinion of DLA Piper (Canada) LLP, counsel to the Company, and Torys LLP, counsel to the Agents, based on the current provisions of the Tax Act in force as of the date hereof and the Tax Proposals, the Offered Shares, if issued on the date hereof, would be 'qualified investments' under the Tax Act by a trust governed by a 'registered retirement savings plan', a 'registered retirement income fund', a 'registered education savings plan', a 'registered disability savings plan', a 'tax-free savings account' (each a 'Registered Plan') or a 'deferred profit sharing plan' ('DPSP') (each as defined in the Tax Act), provided that the Offered Shares are listed on a 'designated stock exchange' as defined in the Tax Act (which currently includes the TSX and the NYSE) or the Company qualifies as a 'public corporation' other than a 'mortgage investment corporation' (as each of those terms are defined in the Tax Act).

Notwithstanding the foregoing, the annuitant, holder or subscriber of a Registered Plan, as the case may be, (each, a 'Registered Holder') will be subject to a penalty tax if the Offered Shares held in a Registered Plan are a 'prohibited investment' for that Registered Plan pursuant to the Tax Act. The Offered Shares will generally be a 'prohibited investment' for a particular Registered Plan if a Registered Holder in respect thereof has a 'significant interest' (as defined in subsection 207.01 of the Tax Act) in the Company or the Registered Holder does not deal at arm's length with the Company for the purposes of the Tax Act. The Offered Shares will not be a prohibited investment if they are 'excluded property' as defined in the Tax Act for trusts governed by a Registered Plan.

Purchasers who intend to hold Offered Shares through a Registered Plan or DPSP should consult their own tax advisors in regard to the application of these rules in their particular circumstances.

AUDITORS

The independent registered public accounting firm of the Company is PricewaterhouseCoopers LLP, Chartered Professional Accountants, Ottawa, Ontario.

The Company changed its auditor to PricewaterhouseCoopers LLP from MNP LLP on January 31, 2020. In accordance with the requirements of NI 51-102, a change of auditor notice and related materials have been filed under

S-32

HEXO's profile on SEDAR. There were no 'reportable events' (within the meaning of NI 51-102) involving MNP LLP.

REGISTRAR AND TRANSFER AGENT

The registrar and transfer agent for the Common Shares is TSX Trust Company at its office in Toronto, Ontario. The co-transfer agent for the Common Shares in the United States is Continental Stock Transfer & Trust Company at its office in New York, New York.

LEGAL MATTERS

Certain legal matters relating to the Offering will be passed upon on our behalf by DLA Piper (Canada) LLP, Toronto, Ontario, with respect to certain legal matters relating to Canadian law, and by DLA Piper LLP (US), with respect to certain legal matters relating to U.S. law, and on behalf of the Agents by Torys LLP, with respect to certain matters relating to Canadian and U.S. law. As of the date hereof, the 'designated professionals' (as such term is defined in Form 51-102F2 - Annual Information Form) of each of DLA Piper (Canada) LLP, DLA Piper LLP (US) and Torys LLP, as a group, beneficially own less than 1% of the outstanding Common Shares.

INTERESTS OF EXPERTS

The Company's audited consolidated financial statements for the years ended July 31, 2020 and 2019 have been incorporated by reference in this Prospectus Supplement and in the Registration Statement of which this Prospectus Supplement forms a part, in reliance upon the reports of our independent registered public accounting firm, PricewaterhouseCoopers LLP, and our former independent registered public accounting firm, MNP LLP, incorporated by reference in this Prospectus Supplement and in the Registration Statement, and upon their authority as experts in accounting and auditing. PricewaterhouseCoopers LLP is independent of the Company within the meaning of the applicable rules and regulations adopted by the Public Company Accounting Oversight Board (United States) and the SEC. MNP LLP was independent of the Company within the meaning of the Rules of Professional Conduct of the Chartered Professional Accountants of Ontario and within the meaning of the applicable rules and regulations adopted by the Public Company Accounting Oversight Board (United States) and the SEC until January 31, 2020.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a corporation existing under the Business Corporations Act (Ontario). All of our directors and officers, and some or all of the experts named in this Prospectus Supplement, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of our and their assets are located outside the United States. We have appointed C T Corporation System, 1015 15th Street N.W., Suite 1000, Washington, DC 20005 as our agent for service of process in the United States, but it may be difficult for holders of Common Shares who reside in the United States to effect service within the United States upon our directors and officers and those experts who are not residents of the United States. It may also be difficult for holders of the Offered Shares who reside in the United States to enforce in the United States judgments of courts of the United States predicated upon our civil liability and the civil liability of our directors, officers and experts under U.S. federal securities laws.

You should not assume that Canadian courts would enforce judgments of United States courts obtained in actions against us or such persons predicated on the civil liability provisions of the U.S. federal securities laws or the securities or 'blue sky' laws of any state within the United States or would enforce, in original actions, liabilities against us or such persons predicated on the U.S. federal securities laws or any such state securities or 'blue sky' laws. We have been advised by our Canadian legal counsel, DLA Piper (Canada) LLP, that a judgment of a U.S. court predicated solely upon civil liability under U.S. federal securities laws would probably 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 by DLA Piper (Canada) LLP, however, that there is substantial doubt whether an action could be brought in Canada in the first instance on the basis of liability predicated solely upon U.S. federal securities laws.

SHORT FORM BASE SHELF PROSPECTUS

HEXO CORP.

$1,200,000,000

COMMON SHARES

WARRANTS

SUBSCRIPTION RECEIPTS

UNITS

This short form base shelf prospectus (the 'Prospectus') relates to the offering for sale by HEXO Corp. (the 'Company' or 'HEXO') from time to time, during the 25-month period that this Prospectus, including any amendments thereto, remains effective, of up to $1,200,000,000 (or the equivalent in other currencies based on the applicable exchange rate at the time of the offering) in the aggregate of: (i) common shares ('Common Shares') in the capital of the Company; (ii) warrants ('Warrants') to purchase other Securities (as defined below); (iii) subscription receipts ('Subscription Receipts') convertible into other Securities; and (iv) units ('Units') comprised of one or more of any of the other Securities, or any combination of such Securities (the Common Shares, Warrants, Subscription Receipts and Units are collectively referred to herein as the 'Securities'). The Securities may be offered in amounts, at prices and on terms to be determined based on market conditions at the time of sale and set forth in an accompanying prospectus supplement (each, a 'Prospectus Supplement'). In addition, the Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or one of its subsidiaries. The consideration for any such acquisition may consist of the Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities. One or more securityholders (each a 'Selling Securityholder') of the Company may also offer and sell Securities under this Prospectus. See 'Selling Securityholders'.

All shelf information permitted under applicable laws to be omitted from this Prospectus will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with this Prospectus except in cases where an exemption from such delivery has been obtained. 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.

The specific terms of any Securities offered will be described in the applicable Prospectus Supplement including, where applicable: (i) in the case of Common Shares, the number of Common Shares offered, the offering price, whether the Common Shares are being offered for cash, and any other terms specific to the Common Shares offered; (ii) in the case of Warrants, the number of Warrants being offered, the offering price, the designation, number and terms of the other Securities purchasable upon exercise of the Warrants, and any procedures that will result in the adjustment of those numbers, the exercise price, the dates and periods of exercise, whether the Warrants are being offered for cash, and any other terms specific to the Warrants offered; (iii) in the case of Subscription Receipts, the number of Subscription Receipts being offered, the offering price, the terms, conditions and procedures for the conversion of the Subscription Receipts into other Securities, the designation, number and

terms of such other Securities, whether the Subscription Receipts are being offered for cash, and any other terms specific to the Subscription Receipts offered; and (iv) in the case of Units, the number of Units being offered, the offering price, the number and terms of the Securities comprising the Units, whether the Units are being offered for cash, and any other terms specific to the Units offered. A Prospectus Supplement relating to a particular offering of Securities may include terms pertaining to the Securities being offered thereunder that are not within the terms and parameters described in this Prospectus. Where required by statute, regulation or policy, and where the Securities are offered in currencies other than Canadian dollars, appropriate disclosure of foreign exchange rates applicable to the Securities will be included in the Prospectus Supplement describing the Securities.

NEITHER THE U.S. SECURITIES AND EXCHANGE COMMISSION (THE 'SEC') NOR ANY U.S. STATE SECURITIES REGULATOR HAS APPROVED OR DISAPPROVED OF THESE SECURITIES OR PASSED ON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

The Company is permitted, under a multi-jurisdictional disclosure system (the 'MJDS') adopted by the securities regulatory authorities in Canada and the United States, to prepare this Prospectus in accordance with Canadian disclosure requirements, which are different from those of the United States. HEXO prepares its financial statements, which are incorporated by reference in this Prospectus, in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and they may not be comparable to the financial statements of United States issuers. The Company's financial statements are audited in accordance with the Public Company Accounting Oversight Board (United States) ('PCAOB') auditing and auditor independence standards but were previously audited in accordance with Canadian auditing and auditor independence standards.

The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely because HEXO is a corporation existing under the laws of the Province of Ontario, Canada, and all or substantially all of its executive offices, administrative activities and assets are located outside the United States. In addition, all of the directors and officers of the Company are residents of jurisdictions other than the United States and all or substantially all of the assets of those persons are or may be located outside the United States. See 'Enforceability of Civil Liabilities'.

Prospective investors should be aware that the purchase of any Securities may have tax consequences in both Canada and the United States that may not be fully described in this Prospectus or in any Prospectus Supplement, and should carefully review the tax discussion, if any, in the applicable Prospectus Supplement, and in any event consult with their own tax advisers before purchasing any of the Securities.

No underwriter or agent has been involved in the preparation of this Prospectus or performed any review of the contents of this Prospectus.

The Company and the Selling Securityholders may offer and sell the Securities to or through underwriters or dealers purchasing as principals, and may also sell directly to one or more purchasers or through agents or pursuant to applicable statutory exemptions. See 'Plan of Distribution'. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, as the case may be, engaged by the Company and/or the Selling Securityholders in connection with the offering and sale of the Securities, and will set forth the terms of the offering of such Securities, including, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents in connection with the offering, the method of distribution of the Securities, the identity of the Selling Securityholders, the initial issue price (in the event that the offering is a fixed price distribution), the proceeds that the Company and/or the Selling Securityholders will, or expect to receive and any other material terms of the plan of distribution.

The Securities may be sold from time to time in one or more transactions at a fixed price or prices or at non-fixed prices. If offered on a non-fixed price basis, the Securities may be offered at market prices prevailing at the time of sale (including, in the case of the Company but not the Selling Securityholders, sales in transactions that are deemed to be 'at-the-market distributions' as defined in National Instrument 44-102 - Shelf Distributions of the

ii

Canadian Securities Administrators ('NI 44-102'), at prices determined by reference to the prevailing price of a specified security in a specified market or at prices to be negotiated with purchasers, in which case the compensation payable to an underwriter, dealer or agent in connection with any such sale will be decreased by the amount, if any, by which the aggregate price paid for Securities by the purchasers is less than the gross proceeds paid by the underwriter, dealer or agent to the Company and/or the Selling Securityholders. The price at which the Securities will be offered and sold may vary from purchaser to purchaser and during the period of distribution.

In connection with any offering of Securities, other than an 'at-the-market distribution' (as defined under applicable Canadian securities legislation), unless otherwise specified in a Prospectus Supplement, the underwriters, dealers or agents, as the case may be, may over-allot or effect transactions which 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. A purchaser who acquires Securities forming part of the underwriters', dealers' or agents' over-allocation position acquires those securities under this Prospectus and the Prospectus Supplement relating to the particular offering of Securities, 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.

The issued and outstanding Common Shares are traded on the Toronto Stock Exchange (the 'TSX') and on the New York Stock Exchange (the 'NYSE'), in each case under the symbol 'HEXO'. On May 6, 2021, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was $8.42 and the closing price of the Common Shares on the NYSE was US$6.91.

Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of Securities (other than Common Shares) will not be listed on any securities exchange. Accordingly, there is currently no market through which the Securities (other than Common Shares) may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. See 'Risk Factors'.

Investing in the Securities is speculative and involves significant risks. Readers should carefully review and evaluate the risk factors contained in this Prospectus, the applicable Prospectus Supplement and in the documents incorporated by reference herein before purchasing any Securities. See 'Forward-Looking Information' and 'Risk Factors'.

Neither the Company nor any Selling Securityholder is making an offer of the Securities in any jurisdiction where such offer is not permitted.

Unless otherwise specified in a Prospectus Supplement relating to any Securities offered, certain legal matters relating to Canadian law in connection with the offering of the Securities will be passed upon on behalf of HEXO by DLA Piper (Canada) LLP, and certain legal matters relating to United States law in connection with the offering of the Securities will be passed upon on behalf of HEXO by DLA Piper LLP (US).

ADDITIONAL INFORMATION

HEXO has filed with the SEC a registration statement on Form F-10 under the United States Securities Act of 1933, as amended, relating to the Securities. This Prospectus, including the documents incorporated by reference into this Prospectus, which forms a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC. Statements included or incorporated by reference in this Prospectus about the contents of any contract, agreement or other documents referred to are not necessarily complete, and in each instance, readers should refer to the exhibits for a complete description of the matter involved. Each such statement is qualified in its entirety by such reference. Each time the Company sells Securities under the registration statement, it will provide a Prospectus Supplement that will contain specific information about the terms of that offering.

HEXO is subject to certain informational requirements of the U.S. Securities Exchange Act of 1934, as amended (the 'U.S. Exchange Act'), in addition to applicable Canadian requirements. Consequently, HEXO files reports and other information with the SEC, in addition to securities regulatory authorities in Canada. Under the MJDS adopted by the United States and Canada, documents and other information that the Company files with the SEC may be prepared in accordance with the disclosure requirements of Canada, which are different from those of the United States. As a 'foreign private issuer' ('FPI') (as defined under United States securities laws), the Company is exempt from the rules under the U.S. Exchange Act prescribing the furnishing and content of proxy statements, and the Company's officers, directors and principal shareholders are exempt from the reporting and short-swing profit recovery provisions contained in Section 16 of the U.S. Exchange Act.

In addition, all of the directors and officers of the Company are residents of jurisdictions other than the United States and all or substantially all of the assets of those persons are or may be located outside the United States.

3

As a result, investors who reside in the United States may have difficulty serving legal process in the United States upon the Company or its directors or officers, as applicable, or enforcing judgments obtained in United States courts against any of them or the assets of any of them located outside the United States, or enforcing against them in the appropriate Canadian court judgments obtained in United States courts, including, but not limited to, judgments predicated upon the civil liability provisions of the federal securities laws of the United States, or bringing an original action in the appropriate Canadian courts to enforce liabilities against the Company or any of its directors or officers, as applicable, based upon United States federal securities laws.

In the United States, the Company has filed with the SEC, concurrently with HEXO's registration statement on Form F-10, an appointment of agent for service of process on Form F-X.

DESCRIPTION OF THE BUSINESS

The following is a summary of information about HEXO and does not contain all the information about HEXO that may be important to prospective investors. Prospective investors should read the more detailed information including, but not limited to, the AIF, financial statements and management's discussion and analysis, that are incorporated by reference into and are considered to be a part of this Prospectus. See 'Documents Incorporated by Reference'.

HEXO is in the business of producing, marketing and selling cannabis through its wholly-owned subsidiary, HEXO Operations Inc., which is a licensed producer under the Cannabis Regulations, from its facilities in Ontario and Québec, and is a leading branded cannabis producer and product innovator.

HEXO's near-term strategy is to be a vertically integrated consumer packaged goods ('CPG') company in the emerging legal adult-use and previously existing medical cannabis markets across Canada, with the intention to expand internationally where regulations allow. HEXO's primary business is to cultivate, process, package and distribute cannabis in order to serve these markets, which it currently does through (i) its 143-acre campus in Gatineau, Québec, which features 1,292,000 sq. ft. of greenhouse cultivation space and 10,000 sq. ft. of advanced automated manufacturing space, and (ii) its processing, manufacturing and distribution centre in Belleville, Ontario, which features 932,190 sq. ft. of commercial space and serves as the Company's main production facility for processing, extraction and packaging and the manufacture of cannabis derivative products.

The Company serves the legalized Canadian adult-use market through its HEXO, HEXO Plus, Up and Original Stash brands and the medical market through its HEXO brand. While the Company will continue to focus on branded cannabis products, it expects to develop its 'Powered by HEXO^®' strategy of introducing cannabinoids into consumer packaged goods, such as edibles, through partnerships with established CPG companies in Canada, the United States and globally.

HEXO's overall strategy is to establish a top global cannabis company with a leading market share in Canada through having strong standards of operational excellence, execution at scale, growing low-cost, high-quality cannabis, building targeted brands for all types of cannabis consumer segments and by partnering with large, established CPG companies to introduce Powered by HEXO^® products across their existing manufacturing and distribution infrastructure. HEXO is focused on building long-term sustainable shareholder value through consistent and profitable sales growth, careful management of selling, general and administrative expenses and maintaining a relatively low depreciable asset base and debt to equity ratio. The strategy is built upon three pillars: operational scalability, innovative products and brand leadership. In striving to achieve operational excellence, the Company's immediate focus remains on effective demand planning and production. The Company is continuously looking to implement more effective techniques to streamline operations, lower production costs, drive meaningful improvements in yields and improve inventory velocity; all as a part of the Company's renewed focus on profitability. The Company's innovation department is actively working towards developing modern, cutting edge cannabis products for the Canadian cannabis derivatives market. The Company plans to invest in even better, science-backed cannabis experiences and platform technology, as it continues to develop advanced ingredients formulations for use with its partners. The Company will continue to use its dominant position in Québec to strengthen distribution across the country with the Company's brands HEXO, HEXO Plus, Up, Original Stash and Bake Sale.

HEXO is centralizing its intellectual property and branding it 'Powered by HEXO^®' with the intention to partner with companies in different facets of the CPG market, enabling them to participate in the cannabis market beginning in Canada and subsequently around the world. Fundamentally, HEXO brings its brand value, cannabinoid isolation and delivery technology, licensed infrastructure and regulatory expertise to established companies, and in turn, HEXO plans to leverage the international distribution, base products and deep understanding of consumer markets of these partners.

Among its other activities, HEXO has entered into the Truss Limited Partnership joint venture with Molson Coors Canada to develop non-alcoholic, cannabis-infused beverages for the adult-use Canadian market. Truss Limited Partnership operates out of the Company's Belleville, Ontario facility. HEXO has also established the Keystone Isolation Technologies Inc. ('KIT') joint venture with Chroma Global Technologies Inc. to develop extraction, refining and isolation technologies for cannabinoids found in both cannabis and hemp that is intended to enable HEXO to bring quality extracts to its partners. Through KIT, HEXO anticipates developing scalable capacity, potency and purity for distillates and isolates that will result in a consistent supply of CBD and THC for the Canadian and global market.

Following the passage of the U.S. Agricultural Improvement Act of 2018 (the '2018 Farm Bill'), the Company is actively working on expansion plans in the United States where and as permitted by applicable U.S. federal and state laws, including U.S. Food and Drug Administration requirements, to take advantage of opportunities in hemp-derived CBD products and markets. Through its wholly-owned subsidiary HEXO USA Inc., HEXO has entered into the Truss CBD USA joint venture with Molson Coors Beverage Company to develop non-alcoholic, hemp-derived CBD beverages in the State of Colorado. Truss CBD USA launched Veryvell^™, a new line of non-alcoholic, sparkling hemp-derived CBD beverages, exclusively available in the State of Colorado, in January 2021. Veryvell^™ is produced and distributed within Colorado state lines following the state's established regulatory framework for hemp-derived CBD in food and beverages and is exclusively distributed by Coors Distributing Company.

HEXO has also established the Keystone Isolation Technologies USA LLC ('KIT USA') joint venture with Chroma Global Technologies Inc. to leverage the technology developed by KIT for its U.S. expansion plans. KIT USA will allow for in state, HEXO controlled cannabis extraction activity to support the manufacturing of CBD beverages and future products in the U.S. In addition to its Truss CBD USA joint venture with Molson Coors Beverage Company in the State of Colorado, the Company is aiming to enter select U.S. states and to offer its 'Powered by HEXO^®' products to U.S. CBD markets via KIT USA and future partners, to the extent that such activities fully comply with applicable laws. The Company has recently appointed a general manager for its U.S. operations who is based in the U.S. and will be responsible for all implementation aspects of U.S. operations, starting in the State of Colorado, including stand up and commissioning of production facilities, overseeing operations, supply chain and logistics, and building the Company's U.S. team. The Company is currently seeking to acquire a facility in Colorado to use for its U.S. expansion plans, and that would be used by KIT USA in particular. The Company anticipates the acquisition costs and subsequent capital expenditures for retrofitting and improvement of this facility would cost approximately US$6.0 million and between US$16.5 million and US$49.5 million respectively. The Company contemplates funding any acquisition costs through existing cash resources while capital expenditures for subsequent retrofitting and improvement would occur in stages over time and be funded through future financing activities.

HEXO only conducts business outside of Canada in jurisdictions where such activities are legally permissible in accordance with the laws of the applicable jurisdictions and the rules and policies of the TSX and the NYSE.

The Company is selectively seeking strategic acquisitions and commercial partnerships and is in various stages of negotiations and due diligence in respect of certain potential acquisition and joint venture, investment or other commercial partnership opportunities, including advanced stage negotiations and due diligence in respect of one possible acquisition. This particular acquisition would involve share consideration and would not be considered either a significant acquisition under the significance tests set out in Part 8 of National Instrument 51-102 -

7

Continuous Disclosure Requirements or a material acquisition as of the date of this Prospectus. There can be no assurance that any of these negotiations will result in acquisitions or joint ventures, investments or other commercial partnerships or, if they do, what the final terms or timing of such acquisitions or joint ventures, investments or other commercial partnerships would be. The Company expects to continue current negotiations and discussions and actively pursue other acquisition and joint venture, investment and other commercial partnership opportunities.

HEXO expects to require significant additional financing for its continued development, growth and current contemplated or future business objectives and expansion plans, including additional anticipated contributions to its Truss Limited Partnership, Truss CBD USA, KIT and KIT USA joint ventures, contemplated U.S. expansion initiatives, potential additional expansion and improvements at its Belleville, Ontario production facility, and possible repayment of certain debts of Zenabis (as defined below) following the completion of the Zenabis Acquisition (as defined below).

Recent Developments

Changes to Board of Directors and Management Team

On November 9, 2020, HEXO announced that Trent MacDonald's security clearance request under the Cannabis Act had been granted by Health Canada, and consequently that he was moving from his acting role of Chief Financial Officer to the permanent role of Chief Financial Officer.

On January 14, 2021, Rose Marie Gage was appointed to HEXO's Board of Directors.

On February 8, 2021, Charles Bowman was appointed General Manager of HEXO's U.S. operations. Mr. Bowman is based in the U.S. and will be responsible for all implementation aspects of HEXO's U.S. operations, starting in the State of Colorado, including stand up and commissioning of production facilities, overseeing operations, supply chain and logistics, and building the Company's U.S. team.

Share Consolidation

On December 17, 2020, the Company completed a consolidation of all of its issued and outstanding Common Shares on the basis of four (4) old Common Shares for one (1) new Common Share (the 'Share Consolidation'). As a result of the Share Consolidation, the Company's issued and outstanding Common Shares were reduced from 488,650,748 to approximately 122,162,687 (disregarding the treatment of any resulting fractional shares). In addition, the exercise or conversion price and the number of Common Shares issuable under the Company's outstanding common share purchase warrants, convertible debentures, stock options and other securities exercisable for or convertible into Common Shares were proportionately adjusted to reflect the Share Consolidation in accordance with the respective terms thereof.

The purpose of the Share Consolidation was to increase the trading price of the Common Shares and regain compliance with the NYSE's US$1.00 minimum share price continued listing standard (the 'NYSE Price Listing Standard'). HEXO had received notification from the NYSE on April 7, 2020 that it was no longer in compliance with the NYSE Price Listing Standard as a result of the average closing price of the Common Shares on the NYSE falling below US$1.00 for a consecutive 30 trading-day period. On January 4, 2021, HEXO received notification from NYSE that it has regained compliance post-Share Consolidation.

Truss CBD USA Product Launch

On January 13, 2021, HEXO announced that Truss CBD USA, a joint venture between HEXO and Molson Coors Beverage Company, had launched Veryvell^™, a new line of non-alcoholic, sparkling hemp-derived CBD beverages, exclusively available in the State of Colorado. Veryvell^™ is produced and distributed within Colorado

8

state lines following the state's established regulatory framework for hemp-derived CBD in food and beverages and is exclusively distributed by Coors Distributing Company. Truss CBD USA is distinct from Truss Beverages, the joint venture between Molson Coors Beverage Company and HEXO in Canada that focuses on non-alcoholic, cannabis-infused beverages.

International Trademark Registration

On January 21, 2021, HEXO announced that following a two-year process, its trademark 'Powered by HEXO^®' was registered by the European Union Intellectual Property Office.

Acquisition of Zenabis Global Inc.

On February 16, 2021, HEXO entered into a definitive arrangement agreement (the 'Arrangement Agreement') with Zenabis Global Inc. ('Zenabis'), under which HEXO will acquire all of Zenabis' issued and outstanding common shares in an all-share transaction valued at approximately $235 million by way of court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the 'Zenabis Acquisition'). Under the terms of the Arrangement Agreement, Zenabis shareholders will receive 0.01772 of a Common Share in exchange for each Zenabis common share held (the 'Exchange Ratio'). Common share purchase warrants, incentive securities and convertible debt securities of Zenabis will be adjusted in accordance with their terms to ultimately become exercisable to receive Common Shares based on the Exchange Ratio. The Arrangement Agreement has been filed under the SEDAR profiles of HEXO and Zenabis on the SEDAR website at www.sedar.com.

Zenabis is a significant Canadian licensed cultivator of medical and recreational cannabis, which is a publicly listed company with its common shares listed for trading on the TSX. Zenabis employs staff coast-to-coast, across facilities in Atholville, New Brunswick; Langley, British Columbia; and Stellarton, Nova Scotia. Zenabis currently has 111,200 kg of licensed cannabis cultivation space across three licensed facilities in Canada, together with its cannabis import, export and processing joint venture, ZenPharm, operating from Birżebbuġa, Malta.

The Zenabis Acquisition needs to be approved by at least 66 2/3% of the votes cast by the shareholders of Zenabis present at a special meeting of Zenabis shareholders to be called by Zenabis to seek approval for the plan of arrangement to effect the Zenabis Acquisition. HEXO has entered into voting support agreements with Zenabis' directors and officers with respect to all Zenabis shares owned by them.

The Arrangement Agreement includes customary provisions, including non-solicitation provisions, subject to the right of Zenabis to accept a superior proposal in certain circumstances, with HEXO having a period of five business days to exercise a right to match any such superior proposal for Zenabis. The Arrangement Agreement also provides for a termination fee of $6.0 million payable by Zenabis to HEXO if the Zenabis Acquisition is terminated in certain specified circumstances, as well as reciprocal expense reimbursement fees if the Zenabis Acquisition is terminated by either party in certain other specified circumstances.

In addition to the approval by Zenabis' shareholders, the Zenabis Acquisition is subject to the receipt of certain regulatory, court and stock exchange approvals and the satisfaction of customary conditions precedent in transactions of this nature as well as the satisfaction of the following additional conditions precedent: (i) the termination and unconditional release of the guarantee provided by Zenabis in favour of Bank of Montreal in connection with the disposition of Bevo Farms Ltd. and its subsidiaries announced by Zenabis on January 4, 2021; (ii) the completion of the Bevo Farms Ltd. sale transaction; and (iii) certain other specified conditions precedent set out in the Arrangement Agreement.

Upon completion of the Zenabis Acquisition, existing HEXO and Zenabis shareholders would respectively own approximately 88% and 12% of HEXO on a pro forma fully-diluted basis. In addition, HEXO has undertaken in the Arrangement Agreement, within 90 days of closing of the Zenabis Acquisition, to increase the size of its Board of Directors by one director and cause one of the current directors of Zenabis, selected by HEXO, to be appointed to the Board of Directors in accordance with HEXO's constating documents.

9

Contemporaneously with the signature of the Arrangement Agreement, Zenabis entered into an agreement with HEXO for the issuance of an unsecured convertible debenture to HEXO in the principal amount of $19.5 million, evidencing both a cash advance extended by HEXO to Zenabis at the end of 2020 as well as a further advance extended to Zenabis contemporaneously with the announcement of the Zenabis Acquisition for the purpose of allowing Zenabis to pay a settlement for a dispute between Zenabis and one of its customers. The unsecured convertible debenture bears interest at a rate of 8% per annum and matures on February 15, 2023. The debenture is convertible, in whole or in part, at any time after the earlier of the termination of the Arrangement Agreement and the then applicable 'Outside Date' thereunder, at the option of HEXO, into common shares of Zenabis at a conversion price equal to the 5-day VWAP of the common shares on TSX for the five trading days prior to the date of conversion. Zenabis has the right to prepay the debenture, at its option and without penalty or premium, at any time after the earlier of the termination of the Arrangement Agreement and the then applicable 'Outside Date' thereunder, subject to HEXO's right to elect to convert the debenture into Zenabis common shares prior to the prepayment. A change of control of Zenabis, other than the Zenabis Acquisition with HEXO, shall result in the mandatory conversion of the debenture into common shares of Zenabis at a conversion price equal to the 5-day VWAP where the last day of the 5-day VWAP of the common shares on TSX shall be the trading day immediately preceding the trading day on which the first of any such change of control transactions is initially publicly announced whether by Zenabis or by the person proposing, intending or agreeing to effect the change of control transaction. The unsecured convertible debenture also contains a provision that prevents HEXO from acquiring, at any given time as a result of and upon conversion of the debenture (other than in respect of a mandatory conversion in the context of a change of control transaction), more than 9.9% of Zenabis' common shares. The listing of the Zenabis common shares issuable pursuant to the conversion of the debenture is subject to the acceptance by the TSX.

Further information regarding the Zenabis Acquisition is included in the information circular that Zenabis has prepared, filed and mailed to its shareholders in connection with its special meeting to be held to consider and seek shareholder approval for the transaction. Zenabis has obtained an interim order from the British Columbia Supreme Court approving various procedural and related matters in order to convene the special meeting, and the special meeting is currently scheduled to be held on May 13, 2021.

The Zenabis Acquisition is not considered a significant probable acquisition under the significance tests set out in Part 8 of National Instrument 51-102 - Continuous Disclosure Requirements as of the date of this Prospectus.

In connection with the Zenabis Acquisition, the Company expects to incur transaction and integration costs on a post-closing consolidated basis of approximately $15.0 million, including change of control payments and legal and other professional, consulting and finder fees. The Company also anticipates repaying certain debts of Zenabis post-closing. Plans for the debt repayments are not yet finalized but are anticipated to involve the repayment of debts in a total amount ranging from approximately $13.7 million to $125.0 million. The Company expects to fund these transaction and integration costs and repayment of certain amounts of the debts through existing cash resources. Additional debt repayments will depend on HEXO's integration plans for Zenabis and the availability of funds from future financing activities.

Repayment of Credit Facility

On April 30, 2021, the Company repaid the total outstanding balance on its credit facility established with certain Canadian Schedule 1 chartered banks in February 2019, together with accrued interest and associated fees, in the amount of approximately $28.9 million.

SHARE STRUCTURE

The authorized capital of the Company consists of an unlimited number of Common Shares and an unlimited number of special shares issuable in series. As of the date of this Prospectus, there are 122,465,534 Common Shares issued and outstanding.

10

The holders of the Common Shares are entitled to one vote per share at all meetings of the shareholders of the Company either in person or by proxy. The holders of Common Shares are also entitled to dividends, if and when declared by the directors of the Company and the distribution of the residual assets of the Company in the event of a liquidation, dissolution or winding up of the Company. The Common Shares rank equally as to all benefits which might accrue to the holders thereof, including the right to receive dividends, voting powers, and participation in assets and in all other respects, on liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, or any other disposition of the assets of the Company among its shareholders for the purpose of winding up its affairs after the Company has paid out its liabilities. The Common Shares are not subject to call or assessment rights or any pre-emptive or conversion rights.

The use of proceeds from the sale of Securities will be described in the applicable Prospectus Supplement relating to a specific offering and sale of Securities. Among other potential uses, the Company may use the net proceeds from the sale of Securities for general corporate purposes, including funding ongoing operations and/or working capital requirements, to repay indebtedness outstanding from time to time, expansion plans in the United States, capital projects and potential future acquisitions, including in relation to international expansion. All expenses relating to an offering of Securities and any compensation paid to underwriting dealers or agents as the case may be, will be paid out of the proceeds from the sale of Securities, unless otherwise stated in the applicable Prospectus Supplement.

The allocation of the net proceeds of any offering will vary depending on future developments in the Company's business operations or unforeseen events, including those listed under the 'Risk Factors' section of this Prospectus and in the documents incorporated herein by reference. For example, the Company generated negative operating cash flow for the year ended July 31, 2020 and the six months ended January 31, 2021. The Company cannot guarantee that it will attain or maintain positive operating cash flow in the future. To the extent the Company has negative cash flows in future periods, certain of the proceeds of any offering may be used to fund such negative operating cash flow in these periods. Management of the Company will retain broad discretion in allocating the net proceeds of any offering of Securities under this Prospectus, as well as the timing of their expenditure, and the Company's actual use of the net proceeds will vary depending on the availability and suitability of investment opportunities and its operating and capital needs from time to time. See 'Risk Factors - Discretion in the Use of Proceeds'.

The Company may, from time to time, issue securities (including Securities) other than pursuant to this Prospectus. The Company will not receive any proceeds from any sale of Securities by a Selling Securityholder.

11

PLAN OF DISTRIBUTION

The Company and the Selling Securityholders may from time to time during the 25-month period that this Prospectus, including any amendments hereto, remains effective, offer for sale and issue up to an aggregate of $1,200,000,000 (or the equivalent in other currencies based on the applicable exchange rate at the time of the offering) in Securities hereunder.

The Company and the Selling Securityholders may offer and sell the Securities to or through underwriters or dealers purchasing as principals, and may also sell directly to one or more purchasers or through agents or pursuant to applicable statutory exemptions. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent, as the case may be, engaged by the Company or any Selling Securityholder in connection with the offering and sale of the Securities, and will set forth the terms of the offering of such Securities, including, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents in connection with the offering, the method of distribution of the Securities, the identity of the Selling Securityholders, the initial issue price, the proceeds that the Company will receive and any other material terms of the plan of distribution. Any initial offering price and discounts, concessions or commissions allowed or re-allowed or paid to dealers may be changed from time to time.

In addition, the Securities may be offered and issued in consideration for the acquisition of other businesses, assets or securities by the Company or one of its subsidiaries. The consideration for any such acquisition may consist of the Securities separately, a combination of Securities or any combination of, among other things, Securities, cash and assumption of liabilities. In addition, one or more Selling Securityholders may sell Securities to or through underwriters or dealers purchasing as principals and may also sell Securities to one or more purchasers directly, through statutory exemptions, or through agents designated from time to time. See 'Selling Securityholders'.

The Securities may be sold from time to time in one or more transactions at a fixed price or prices or at 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, the NYSE or other existing trading markets for the Common Shares. The price at which the Securities will be offered and sold may vary from purchaser to purchaser and during the period of distribution.

In connection with the sale of the Securities, underwriters, dealers or agents may receive compensation from the Company, any Selling Securityholder or from other parties, including in the form of underwriters', dealers' or agents' fees, commissions or concessions. Underwriters, dealers and agents that participate in the distribution of the Securities may be deemed to be underwriters for the purposes of applicable Canadian and/or U.S. securities legislation and any such compensation received by them from the Company or any Selling Securityholder and any profit on the resale of the Securities by them may be deemed to be underwriting commissions.

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.

Underwriters, dealers or agents who participate in the distribution of the Securities may be entitled, under agreements to be entered into with the Company and/or any Selling Securityholder, to indemnification by the Company and/or any Selling Securityholder against certain liabilities, including liabilities under Canadian and/or U.S. securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. Such underwriters, dealers and agents may be customers of, engage in transactions with, or perform services for, the Company in the ordinary course of business.

12

Unless otherwise specified in the applicable Prospectus Supplement, each series or issue of Securities (other than Common Shares) will be a new issue of Securities with no established trading market. Accordingly, there is currently no market through which the Securities (other than Common Shares) may be sold and purchasers may not be able to resell such Securities purchased under this Prospectus. This may affect the pricing of such Securities in the secondary market, the transparency and availability of trading prices, the liquidity of such Securities and the extent of issuer regulation. See 'Risk Factors'.

SELLING SECURITYHOLDERS

This Prospectus may also, from time to time, relate to the offering of the Securities by way of a secondary offering by certain Selling Securityholders.

The terms under which the Securities may be offered by Selling Securityholders will be described in the applicable Prospectus Supplement. The Prospectus Supplement for or including any offering of Securities by Selling Securityholders will include, without limitation, where applicable: (i) the names of the Selling Securityholders; (ii) the number and type of Securities owned, controlled or directed by each Selling Securityholder; (iii) the number of Securities being distributed for the accounts of each Selling Securityholder; (iv) the number of Securities to be owned, controlled or directed by each Selling Securityholder after the distribution and the percentage that number or amount represents out of the total number of outstanding Securities; (v) whether the Securities are owned by the Selling Securityholders, both of record and beneficially, of record only or beneficially only; (vi) if a Selling Securityholder purchased any of the Securities held by him, her or it in the 12 months preceding the date of the Prospectus Supplement, the date or dates the Selling Securityholder acquired the Securities; (vii) if a Selling Securityholder acquired the Securities held by him, her or it in the 12 months preceding the date of the Prospectus Supplement, the cost thereof to the Selling Securityholder in the aggregate and on a per security basis; and (viii) the disclosure required by Item 1.11 of Form 44-101F1 - Short Form Prospectus and Selling Securityholders will file a non-issuer's submission to jurisdiction form with the applicable Prospectus Supplement.

The Common Shares are currently listed on the TSX and on the NYSE, in each case under the trading symbol 'HEXO'. Trading price and volume of the Common Shares will be provided, as required, in each Prospectus Supplement.

DIVIDENDS

HEXO has never paid any dividends on its Common Shares. HEXO does not intend to pay any dividends on the Common Shares in the foreseeable future. In addition, HEXO is restricted from paying dividends pursuant to certain solvency tests prescribed by applicable corporate law and is currently subject to contractual restrictions on the payment of dividends if any event of default under its outstanding convertible unsecured debentures occurs. Any decision to pay dividends on the Common Shares in the future will be at the discretion of the Company's Board of Directors and will depend on, among other things, the Company's results of operations, current and anticipated cash requirements and surplus, financial condition, any contractual restrictions and financing agreement covenants, the solvency tests imposed by corporate law and other factors that the Board of Directors may deem relevant.

CERTAIN CANADIAN AND UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

Owning any of the Securities may subject holders to tax consequences. The applicable Prospectus Supplement may describe certain Canadian federal income tax consequences to an initial investor who is a resident of Canada or a non-resident of Canada of acquiring, owning and disposing of any of the Securities offered thereunder. The applicable Prospectus Supplement may also describe certain United States federal income tax consequences of the acquisition, ownership and disposition of any of the Securities offered thereunder by an initial investor who is a U.S. Person (within the meaning of the U.S. Internal Revenue Code of 1986, as amended). Prospective investors should consult their own tax advisers prior to deciding to purchase any of the Securities.

16

RISK FACTORS

Before deciding to invest in any Securities, prospective investors of the Securities should consider carefully the risk factors and the other information contained and incorporated by reference in this Prospectus and the applicable Prospectus Supplement relating to a specific offering of Securities before purchasing the Securities, including those risks identified and discussed under the heading 'Risk Factors' in the AIF, which is incorporated by reference herein. See 'Documents Incorporated by Reference'.

An investment in the Securities offered hereunder is speculative and involves a high degree of risk. The risks and uncertainties described or incorporated by reference herein are not the only ones the Company may face. Additional risks and uncertainties, including those that the Company is unaware of or that are currently deemed immaterial, may also become important factors that affect the Company and its business. If any such risks actually occur, the Company's business, financial condition and results of operations could be materially adversely affected.

Prospective investors should carefully consider the risks below and in the AIF and the other information elsewhere in this Prospectus and the applicable Prospectus Supplement and consult with their professional advisors to assess any investment in the Company.

Risks Related to the Securities

Return on Securities is not Guaranteed

There is no guarantee that the Securities will earn any positive return in the short term or long term. A holding of Securities is speculative and involves a high degree of risk and should be undertaken only by holders whose financial resources are sufficient to enable them to assume such risks and who have no need for immediate liquidity in their investment. A holding of Securities is appropriate only for holders who have the capacity to absorb a loss of some or all of their holdings.

Discretion in the Use of Proceeds

Management of the Company will have broad discretion with respect to the application of net proceeds received by the Company from the sale of Securities under this Prospectus or a future Prospectus Supplement and may spend such proceeds in ways that do not improve the Company's results of operations or enhance the value of the Common Shares or its other securities issued and outstanding from time to time. Any failure by management to apply these funds effectively could result in financial losses that could have a material adverse effect on the Company's business or cause the price of the securities of the Company issued and outstanding from time to time to decline.

Dilution

The Company may sell additional Common Shares or other Securities that are convertible or exchangeable into Common Shares in subsequent offerings or may issue additional Common Shares or other Securities to finance future acquisitions. The Company cannot predict the size or nature of future sales or issuances of securities or the effect, if any, that such future sales and issuances will have on the market price of the Common Shares. Sales or issuances of substantial numbers of Common Shares or other Securities that are convertible or exchangeable into Common Shares, or the perception that such sales or issuances could occur, may adversely affect prevailing market prices of the Common Shares. With any additional sale or issuance of Common Shares or other Securities that are convertible or exchangeable into Common Shares, investors will suffer dilution to their voting power and economic interest in the Company. Furthermore, to the extent holders of the Company's stock options or other convertible securities convert or exercise their securities and sell the Common Shares they receive, the trading price of the Common Shares on the TSX and the NYSE may decrease due to the additional amount of Common Shares available in the market.

17

Volatile Market Price of the Common Shares

The market price of the Common Shares may be volatile and subject to wide fluctuations in response to numerous factors, many of which are beyond the Company's control. This volatility may affect the ability of holders of Common Shares to sell their securities at an advantageous price. Market price fluctuations in the Common Shares may be due to the Company's operating results failing to meet expectations of securities analysts or investors in any period, downward revision in securities analysts' estimates, adverse changes in general market conditions or economic trends, acquisitions, dispositions or other material public announcements by the Company or its competitors, along with a variety of additional factors. These broad market fluctuations may adversely affect the market price of the Common Shares.

Financial markets historically at times experienced significant price and volume fluctuations that have particularly affected the market prices of equity securities of companies and that have often been unrelated to the operating performance, underlying asset values or prospects of such companies. Accordingly, the market price of the Common Shares may decline even if the Company's operating results, underlying asset values or prospects have not changed. Additionally, these factors, as well as other related factors, may cause decreases in asset values that are deemed to be other than temporary, which may result in impairment losses. There can be no assurance that continuing fluctuations in price and volume will not occur. If such increased levels of volatility and market turmoil continue, the Company's operations could be adversely impacted and the trading price of the Common Shares may be materially adversely affected.

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 and the NYSE or achieve listing on any other public listing exchange.

There is currently no market through which the Securities, other than the Common Shares, may be sold and, unless otherwise specified in the applicable Prospectus Supplement, none of the Warrants, Subscription Receipts or Units will be listed on any securities or stock exchange or any automated dealer quotation system. As a consequence, purchasers may not be able to resell Warrants, Subscription Receipts or Units purchased under this Prospectus or any Prospectus Supplement. This may affect the pricing of the Securities, other than the Common Shares, in the secondary market, the transparency and availability of trading prices, the liquidity of these securities and the extent of issuer regulation. There can be no assurance that an active trading market for the Securities, other than the Common Shares, will develop or, if developed, that any such market, including for the Common Shares, will be sustained.

Risks Related to the Company and its Business

COVID-19

The outbreak of the novel coronavirus, or COVID-19, which was declared a pandemic by the World Health Organization in March 2020, has spread across the globe and is impacting economic activity worldwide. In response to the outbreak, governmental authorities in Canada and internationally have introduced various recommendations and measures to try to limit the pandemic, including travel restrictions, border closures, non-essential business closures, quarantines, self-isolations, shelters-in-place and social distancing. The COVID-19 pandemic and the response of governmental authorities to try to limit it have had, and continue to have, a significant impact on the private sector and individuals, including unprecedented business, employment and economic disruptions.

Since the outbreak of the pandemic, the Company has taken various steps to mitigate the impact of COVID-19, including implementing precautionary measures at its facilities to ensure the safety of its staff and product

18

consumers. These measures include: the formation of a COVID-19 response team which is tasked to manage the Company's information flow of COVID-19 updates, review public health and safety protocols as outlined by the appropriate governmental authorities and develop in house action plans to mitigate these risks and comply accordingly; the transfer of all functions possible to work from home; for those functions which need to remain 'on site', the implementation of precautionary measures involving social distancing, full personal protective equipment such as gloves and masks, and additional personal sanitation stations throughout our manufacturing and administrative facilities; the implementation of travel restrictions for work-related travel where deemed unnecessary; restricted visitor access to our facilities; and initiation of a 'Hero Pay' program to support our cultivation and manufacturing employees who continue to work during the pandemic.

Fortunately, the Company's operations, results and financial position have not been materially impacted by COVID-19 related issues. We have not experienced material disruptions in our labour inputs and cultivation and processing activities, there have been no indicators of material issues to our supply chain, and on the consumer side, product demand has remained stable and cannabis retail has been declared an essential service across Canada and, as such, our provincial distribution remains relatively unimpeded. While it remains uncertain as to whether COVID-19 will ultimately increase or diminish demand and sales of cannabis across Canada, we continue to work with provincial and private entities towards the goal of penetrating deeper into all markets and allow for the public to safely and reliably consume our products. We currently do not foresee any impact to supply to the market and, therefore, any impact on our cultivation, manufacturing and producing activities. However, despite these mitigation steps and the minimal impact on the Company's business to date, the continued presence and spread of COVID-19 nationally and globally could have a material adverse impact on our business, operations, financial results, position and prospects, including through disruptions in our cultivation and processing activities, supply chains and sales channels, and a reduction in supply of, or demand for, the Company's products.

Persistent social distancing measures and restrictions imposed by the federal, provincial and territorial governments in Canada on the movement of individuals and the distribution of cannabis in the country may adversely affect the Company's cannabis sales. It is difficult for the Company to predict how the COVID-19 pandemic may affect the Company's business in the future, including the effect it may have (positive or negative; long or short term) on the price of, and demand for, cannabis. It is possible that the COVID-19 pandemic could have a material adverse effect on the Company's business, financial condition, results of operations and prospects as well as the market for its securities and/or its ability to obtain financing. The extent to which the COVID-19 pandemic impacts the Company's results will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the duration of the outbreak, the severity of the virus, and the actions taken to contain its impact.

In addition, COVID-19 is impacting cannabis retail sales channels and may adversely affect the Company's ability to successfully market and sell its products. While cannabis retail has been declared an essential service by provincial governments, with retailers continuing to operate with a mix of online and in-store sales and curbside pick-up and/or delivery services, and while licensed producers can continue production, the situation is uncertain. Moreover, sales volumes of cannabis may be adversely impacted by consumer 'social distancing' behaviours. What further impact, if any, the COVID-19 pandemic may have on cannabis retail markets is unpredictable. The COVID-19 pandemic may also negatively impact service levels with Health Canada, which licences and regulates the Company's operations. The continued spread of COVID-19 nationally and globally could also lead to a deterioration of general economic conditions including a possible national or global recession.

Due to the speed with which the COVID-19 situation is developing and the uncertainty of its magnitude, outcome and duration, it is not possible to estimate its impact on our business, operations or financial results; however, the impact could be material. The Company continues to monitor the situation and work with its stakeholders, including employees, customers and suppliers, in order to assess further possible implications to its business, supply chain and customers, and, where practicable, mitigate adverse consequences and responsibly address this global pandemic.

19

Reliance on Licences and Licence Renewals

HEXO's business operations are dependent on being licensed under the Cannabis Act. All licences must be renewed annually or as otherwise provided in each licence. HEXO currently holds four licences having expiry dates ranging between December 6, 2022 and October 25, 2024. Prior to the expiry of each licence, HEXO must submit to Health Canada an application for renewal of the licence containing information prescribed by the Cannabis Act. Failure to comply with the requirements of the licences or any failure to renew all or any of the licences would have a material adverse impact on the business, financial condition, results of operations and prospects of HEXO.

HEXO believes it is complying in all material respects with the terms of its licences and it is not aware of any reason why it would not be able to renew its licences upon their expiry. However, there can be no guarantee that Health Canada will renew all or any of the licences, or that any renewals will occur in a timely fashion or on terms similar to HEXO's existing licences or otherwise acceptable to HEXO and its business. Should Health Canada not renew HEXO's licences, delay the renewal of the licences or renew the licences on different terms, the business, financial condition, results of operations and prospects of HEXO would be materially adversely affected.

Regulatory Risks

The adult-use and medical cannabis industries and markets are subject to a variety of laws in Canada, the United States and elsewhere.

In Canada, the Cannabis Act came into force on October 17, 2018, legalizing the sale of cannabis for adult recreational use. Prior to the Cannabis Act coming into force, only the sale of medical cannabis was legal. The Cannabis Act and regulations thereunder provides a licensing and regulatory scheme governing the production, importation, exportation, testing, packaging, labelling, delivery, transportation, sale, possession and disposal of cannabis for non-medical (i.e., adult use) use, and medical use. Further, on October 17, 2019, targeted amendments to the Cannabis Act and Cannabis Regulations came into force, adding three new authorized classes of cannabis for sale: edibles, extracts and topicals.

In the United States, despite cannabis having been legalized at the state level for medical use in many states and for adult use in a number of states, cannabis containing 0.3% or more THC continues to be categorized as a Schedule I controlled substance under the Controlled Substances Act (the 'CSA') and subject to the Controlled Substances Import and Export Act (the 'CSIEA'). HEXO does not currently produce or distribute any cannabis products in the United States or accept payments from any party that does so. While HEXO is entering into the U.S. CBD market, it will only do so in full compliance with the CSA, the CSIEA and all other applicable federal and state laws. Therefore, HEXO believes that it is not and will not become subject to the CSA or CSIEA. Nonetheless, violations of any U.S. federal laws and regulations, such as the CSA and the CSIEA, could result in significant fines, penalties, administrative sanctions, convictions or settlements arising from civil proceedings initiated by either the U.S. federal government or private citizens or criminal charges, including, but not limited to, disgorgement of profits, cessation of business and activities or divestiture.

The business and activities of the Company are heavily regulated in all jurisdictions where it carries on business. The Company's operations are subject to various laws, regulations and guidelines by governmental authorities, particularly Health Canada, relating to the manufacture, marketing, management, transportation, storage, sale and disposal of cannabis, and also including laws and regulations relating to health and safety, the conduct of operations and the protection of the environment. Laws and regulations, applied generally, grant government agencies and self-regulatory bodies broad administrative discretion over the activities of the Company, including the power to limit or restrict business activities as well as impose additional disclosure requirements on the Company's products and services.

The Company is dependent upon regulatory approvals and licences for its ability to grow, process, package, store and sell its products. Achievement of the Company's business objectives are contingent, in part, upon ongoing

20

compliance with regulatory requirements implemented by these governmental authorities and obtaining all regulatory approvals, where necessary, for the production and sale of its products. The Company cannot predict the time required to secure all appropriate regulatory approvals for its products, or the extent of testing and documentation that may be required by governmental authorities. Any delays in obtaining, or failure to obtain regulatory approvals would significantly delay the development of markets and products and could have a material adverse effect on the business, financial condition, results of operations and prospects of the Company.

Further, HEXO is subject to ongoing inspections by Health Canada to monitor HEXO's compliance with its licencing requirements. HEXO's existing licences and any new licences that it may obtain in the future in Canada or other jurisdictions may be revoked or restricted at any time in the event that HEXO is found not to be in compliance. Should HEXO fail to comply with the applicable regulatory requirements or with conditions set out under its licences or should its licences be revoked, HEXO may not be able to continue producing or distributing cannabis in Canada. Failure to comply with the laws and regulations applicable to its operations may lead to possible sanctions including the revocation or imposition of additional conditions on licences to operate the Company's business; the suspension or expulsion from a particular market or jurisdiction or of its key personnel; product recalls or seizures; and, the imposition of fines and censures or criminal charges.

In addition, we may be subject to enforcement proceedings resulting from a failure to comply with applicable regulatory requirements in Canada or other jurisdictions, which could result in:

These enforcement actions could delay or entirely prevent the Company from continuing the production, testing, marketing, sale or distribution of its products and divert management's attention and resources away from its business operations. In addition, changes in regulations, government or judicial interpretation of regulations, or more vigorous enforcement thereof or other unanticipated events could require extensive changes to our operations, increase compliance costs or give rise to material liabilities or a revocation of our licences and other permits. Furthermore, governmental authorities may change their administration, application or enforcement procedures at any time, which may adversely impact our ongoing regulatory compliance costs. There is no assurance that we will be able to comply or continue to comply with applicable regulations.

To the extent that there are changes to the existing or the enactment of future laws and regulations that affect the sale or offering of the Company's product or services in any way, the Company's revenues may be adversely affected.

Regulatory Developments

The commercial adult-use and medical cannabis industry is a relatively new industry in Canada. The effect of Health Canada's application, administration and enforcement of the regime established by it to regulate the industry on HEXO and its business in Canada, or the application, administration and enforcement of the laws of other countries by the applicable regulators in those countries, may significantly delay or impact HEXO's ability to participate in the Canadian adult-use and medical cannabis markets or, potentially, adult-use and medical cannabis markets outside Canada, to develop, produce and sell cannabis products.

21

Further, Health Canada or other applicable regulatory authorities may change their application, administration or interpretation of the applicable regulations or their compliance or enforcement procedures at any time. Any such changes could require HEXO to revise its ongoing compliance procedures, requiring it to incur increased compliance costs and expend additional resources. There is no assurance that HEXO will be able to comply or continue to comply with applicable regulations.

Development of Canadian Adult-Use Recreational Market

The Cannabis Act and Cannabis Regulations came into effect on October 17, 2018 and govern the federal legalization and regulation of adult-use cannabis in Canada. The Cannabis Act sets out broad prohibitions on the promotion of cannabis. Under the Cannabis Act, subject to certain limited exceptions, it is prohibited to promote cannabis, cannabis accessories or any service related to cannabis, including: (i) by means of a testimonial or endorsement; (ii) doing so in a manner where there are reasonable grounds to believe it could be appealing to young persons; and (iii) presenting it or any of its brand elements in a manner that associates it or the brand element with or evokes a positive or negative emotion about or image of a way of life, such as one that includes glamour, recreation, excitement, vitality, risk or daring. The Cannabis Act also sets out strict requirements for packaging.

Further, on October 17, 2019, targeted amendments to the Cannabis Act and Cannabis Regulations came into force, adding three new authorized classes of cannabis for sale: edibles, extracts and topicals. The amendments introduced new regulatory controls to address sale of the new product classes, content and product specifications, packaging and licensing requirements. The effect of Health Canada's administration, application and enforcement of this new regulatory regime on the Company is unknown and the interpretation and application of the regulations may change at any time, or their implementation may be delayed. There is no assurance that the Company will be able to comply with these new regulations.

In addition, the governments of every Canadian province and territory have enacted and implemented their respective regulatory regimes for the distribution and sale of cannabis for adult-use purposes within those jurisdictions. Various different models for distribution and sale have been implemented in each jurisdiction across Canada including government-operated retail and/or distribution models, privately operated retail and/or distribution models and hybrid approaches. These provincial or territorial legislation and regulatory regimes may change in ways that impact our ability to continue our business as currently conducted or proposed to be conducted. There is no guarantee that provincial or territorial regulatory regimes governing the distribution and sale of cannabis for adult-use purposes in each jurisdiction will remain as currently enacted or that any such legislation and regulation will create the growth opportunities that the Company currently anticipates. The federal and provincial or territorial legislation and regulatory regimes for cannabis products also include excise duties payable by licensed cannabis producers on adult-use cannabis products, in addition to goods and services tax/harmonized sales tax in certain provinces and territories. The rate of the excise duties for cannabis products varies by province and territory. Any significant increase in the rate of excise duties on cannabis products in the future could reduce consumer demands for cannabis products and adversely impact the adult-use cannabis industry and market in general. In addition, any increase in the rate of excise duties on cannabis products in the future could reduce the Company's margins and profitability in the event that the Company could not or chose not to pass along such increases to consumers. Any of the foregoing could result in a material adverse effect on the Company's business, financial condition, results of operations and prospects.

Cash Flow from Operations and Need for Additional Financing

The Company generated negative operating cash flow for the year ended July 31, 2020 and the six months ended January 31, 2021. The Company cannot guarantee that it will attain or maintain positive operating cash flow in the future. To the extent that the Company has negative cash flows in future periods, certain of the proceeds of any offering may need to be allocated to funding this negative cash flow in addition to the Company's operational expenses or other activities. Moreover, HEXO may require additional financing to fund its operations to the point where it is generating positive cash flows, and continued negative cash flow may restrict HEXO's ability to pursue its business objectives.

22

As at April 30, 2021, and following the Company's repayment of the total outstanding balance on its credit facility, the Company had approximately $81.0 million in cash and approximately $240.0 million in working capital. The Company's existing cash and working capital are expected to provide sufficient liquidity to meet necessary cash outflow requirements for at least the next twelve months. If additional liquidity is required, management plans to secure the necessary financing through the issuance of new public or private equity or debt instruments. There is no assurance that additional future funding will be available to the Company, or that it will be available on terms which are acceptable to management.

However, HEXO expects to require significant additional financing for its continued development, growth and current contemplated or future business objectives and expansion plans, including additional anticipated contributions to its Truss Limited Partnership, Truss CBD USA, KIT and KIT USA joint ventures, contemplated U.S. expansion initiatives, potential additional expansion and improvements at its Belleville, Ontario production facility, and possible repayment of Zenabis debts following the completion of the Zenabis Acquisition. The failure to raise such capital could result in the delay or indefinite postponement of all or any of the Company's current contemplated or future business objectives and expansion plans and impede its continued development and growth. There can be no assurance that additional capital or other types of financing will be available if needed or that, if available, the terms of such financing will be favorable to HEXO. If additional funds are raised through 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 holders of Common Shares.

In addition, from time to time, HEXO may enter into transactions to acquire assets or the shares of other corporations. These transactions may be financed wholly or partially with debt, which may temporarily increase HEXO's debt levels above industry standards. 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 HEXO to obtain additional capital and to pursue business opportunities, including potential acquisitions.

Restrictions on U.S. Activities

HEXO only conducts business outside of Canada in jurisdictions where such activities are legally permissible in accordance with the laws of the applicable jurisdictions and the rules and policies of the TSX and the NYSE. Following the passage of the 2018 Farm Bill, the Company is actively working on expansion plans in the United States where and as permitted to take advantage of opportunities in hemp-derived CBD products and markets, such as the Truss CBD USA joint venture with Molson Coors Beverage Company in the State of Colorado and the establishment of KIT USA. The Company expects to use a portion of the proceeds from the Offering for these expansion plans.

The passage of the 2018 Farm Bill in December 2018 removed industrial hemp and hemp-derived products with a THC concentration of not more than 0.3% (dry weight basis) from Schedule I of the U.S. Controlled Substances Act (the 'CSA'). This has the effect of legalizing the cultivation of industrial hemp for commercial purposes, including the production of CBD and other cannabinoids, except for THC, subject to regulations to be developed by the U.S. Department of Agriculture. Despite cannabis having been legalized at the state level for medical use in many states and for adult use in a number of states, cannabis containing 0.3% or more THC continues to be categorized as a Schedule I controlled substance under the CSA and subject to the U.S. Controlled Substances Import and Export Act (the 'CSIEA').

CBD is increasingly used as an ingredient in food and beverages, as an ingredient in dietary supplements and as an ingredient in cosmetics, thereby generating new investments and creating employment in the cultivation and processing of hemp and hemp-derived products. Foods and beverages, dietary supplements, pharmaceuticals, and cosmetics containing CBD are all subject to regulation under the U.S. Federal Food, Drug and Cosmetics Act (the 'FDCA'). The FDA has asserted that CBD is not a lawful ingredient in foods and beverages, supplements

23

and pharmaceuticals (unless FDA-approved). As such, in the future if it decided to commercialize products containing CBD, and although the Company would work to maintain compliance with all applicable regulatory requirements, any potential FDA enforcement action against the Company could result in a number of negative consequences, including fines, disgorgement of profits, recalls or seizures of products, or a partial or total suspension of the Company's production or distribution of its products.

HEXO does not currently produce or distribute any cannabis products in the United States or accept payments from any party that does so. While HEXO is entering into the U.S. CBD market, it will do so in full compliance with the CSA, the CSIEA, the FCDA and all other applicable federal and state laws. Nonetheless, violations of any U.S. federal laws and regulations could result in significant fines, penalties, administrative sanctions, convictions or settlements arising from civil proceedings initiated by either the U.S. federal government or private citizens or criminal charges, including, but not limited to, disgorgement of profits, cessation of business and activities or divestiture.

HEXO's U.S. expansion plans are also subject to the rules of the TSX. On October 16, 2017, the TSX provided clarity regarding the application of Sections 306 (Minimum Listing Requirements) and 325 (Management) and Part VII (Halting of Trading, Suspension and Delisting of Securities) of the TSX Company Manual (collectively, the 'TSX Requirements') to applicants and TSX-listed issuers with business activities in the cannabis sector. In TSX Staff Notice 2017-0009, the TSX notes that issuers with ongoing business activities that violate U.S. federal law regarding cannabis are not in compliance with the TSX Requirements. These business activities may include (i) direct or indirect ownership of, or investment in, entities engaging in activities related to the cultivation, distribution or possession of cannabis in the U.S., (ii) commercial interests or arrangements with such entities, (iii) providing services or products specifically targeted to such entities, or (iv) commercial interests or arrangements with entities engaging in providing services or products to U.S. cannabis companies. The TSX reminded issuers that, among other things, should the TSX find that a listed issuer is engaging in activities contrary to the TSX Requirements, the TSX has the discretion to initiate a delisting review. Failure by the Company to comply with the requirements could have an adverse effect on its business.

HEXO does not engage in any U.S. cannabis-related activities as defined in Canadian Securities Administrators Staff Notice 51-352, and does not engage in any other activities involving cannabis or hemp with any level of THC or CBD in the United States except to the extent fully in compliance with U.S. federal law and all applicable state laws. We only conduct business in jurisdictions outside of Canada where such operations are legally permissible in accordance with all of the federal laws, and the state, provincial or similar laws, of the foreign jurisdiction, the federal, provincial and territorial laws of Canada and our regulatory obligations to the TSX. In addition, HEXO does not currently have any partnerships, joint ventures or similar arrangements with U.S.-based companies that may themselves participate in the U.S. cannabis market except in compliance with U.S. federal law and all applicable state laws.

Investment Company Act Status

The U.S. Investment Company Act of 1940, as amended (the 'Investment Company Act'), prohibits a non-U.S. issuer that is an 'investment company' as defined therein from making public offers or sales of securities in the United States. An issuer generally will be deemed to be an 'investment company' for purposes of the Investment Company Act if it owns or proposes to acquire 'investment securities' having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis.

While we do not currently believe we are an 'investment company,' we hold assets that are investment securities, including our interests in Truss Limited Partnership and Truss CBD USA. We do not control the ability to restructure the Truss arrangement such that it is not an investment security. We also intend to enter into other joint ventures or similar arrangements, which may involve investment securities. If the value of our interests in Truss Limited Partnership and Truss CBD USA, in other joint ventures or in other investment securities relative to our total assets were to increase, we may be deemed to be an investment company. In that

24

case, we may not be able to raise additional funds through public offers and sales of securities in the United States. We would not be able to avoid this outcome by registering as an investment company under the Investment Company Act because the Investment Company Act generally prohibits non-U.S. entities from registering and also imposes many restrictions on the capital structure, governance, and activities of registered investment companies, which we would be unable to comply with.

PFIC Status

Based upon the nature of the Company's current business activities, the Company does not believe it was a 'passive foreign investment company' ('PFIC') for U.S. income tax purposes for its 2020 fiscal year, and does not expect to be a PFIC in its current taxation year. However, the tests for determining PFIC status are based upon the composition of the income and assets of the Company and its subsidiaries and affiliates from time to time, and it is difficult to make accurate predictions of future income and assets. Accordingly, there can be no assurance that the Company will not become a PFIC in the future. A non-U.S. corporation generally will be considered a PFIC for any taxable year if either: (i) at least 75% of its gross income is passive income; or (ii) at least 50% of the value of its assets is attributable to assets that produce or are held for the production of passive income (which generally includes cash). If the Company were to be classified as a PFIC for any taxation year, such characterization could result in adverse U.S. income tax consequences to certain investors in the Company in the United States.

Risks Relating to the Zenabis Acquisition

There can be no assurance that the Company will complete the Zenabis Acquisition. The completion of the Zenabis Acquisition is subject to the satisfaction of a number of conditions which include, among others, obtaining necessary approvals, including approval of the shareholders of Zenabis, and the performance by Zenabis and HEXO of their respective obligations and covenants in the Arrangement Agreement.

The Zenabis Acquisition may not be completed, or may not be completed on the terms currently anticipated, as a result of a number of factors, including the failure of the parties to obtain necessary approvals or satisfy one or more of the conditions to closing. There can be no assurance the approvals will be obtained or the conditions to closing will be satisfied or waived, or that other events will not intervene to delay or result in the failure to close the Zenabis Acquisition. Delays in closing the Zenabis Acquisition or the failure to close the Zenabis Acquisition may result in the Company incurring additional costs in connection with such delay, termination of the Arrangement Agreement and/or the failure to achieve the anticipated benefits of the Zenabis Acquisition. Any delay in closing or a failure to close the Zenabis Acquisition could also have a negative impact on the Company's business and the trading price of the Common Shares. For instance, the Company could experience negative reactions from the financial markets, which could cause a decrease in the market price of the Common Shares, particularly if the market price reflects market assumptions that the Zenabis Acquisition will be completed or completed on certain terms. There could also be negative impact on the Company's ability to attract future acquisition opportunities.

The business and operations of Zenabis are outside HEXO's control until completion of the Zenabis Acquisition. Although the Arrangement Agreement contains certain covenants on the part of Zenabis regarding the operation of its business prior to closing the Zenabis Acquisition, the Company will not control Zenabis until the completion of the Zenabis Acquisition, and Zenabis' business and results of operations may be adversely affected by events that are outside of the Company's control during the interim period.

The historic and current performance of Zenabis' business and operations may not be indicative of its success in future periods, and the future performance of Zenabis' business may be influenced by, among other factors, general economic conditions, unfavorable regulatory decisions, litigation, the occurrence or discovery of new liabilities and other factors beyond our and Zenabis' control. As a result of any one or more of these factors, among others, the operations and financial performance of Zenabis may be negatively affected, which may adversely affect the future financial results of both Zenabis and the Company.

25

There can be no assurance that HEXO will be able to successfully integrate Zenabis with its business or otherwise realize the expected benefits of the Zenabis Acquisition. Achieving the potential benefits of the acquisition of Zenabis will depend in part on HEXO's ability to successfully integrate the functions, operations, information technology and accounting systems and personnel of Zenabis in a timely and efficient manner, as well as on HEXO's ability to realize the anticipated growth opportunities and synergies, efficiencies and cost savings from integrating Zenabis with its business following completion of the Zenabis Acquisition. Special risks related to the Zenabis Acquisition and integration of Zenabis exist, including possible unanticipated costs and liabilities, unanticipated weaknesses in internal controls, diversion of management's attention and the loss of key employees or customers. A variety of factors, including the risk factors set forth in this Prospectus and the documents incorporated by reference herein, may also adversely affect the likelihood of the anticipated benefits of the acquisition.

Although the completion of the Zenabis Acquisition is not currently expected to have a material impact on HEXO's revenue or expenses in 2021, the Company has incurred, and expect to continue to incur, a number of costs associated with the completion of the Zenabis Acquisition, the integration of Zenabis into the Company's operations and achieving the desired synergies. HEXO will incur transaction fees and costs related to formulating and implementing integration plans, including facilities and systems consolidation costs and employment-related costs. Other non-recurrent transaction costs related to the Zenabis Acquisition include, but are not limited to, fees paid to legal, financial and accounting advisors, as well as other related costs. HEXO continues to assess the magnitude of these costs, and additional unanticipated costs may be incurred in the acquisition and integration of the two companies' businesses. In addition, even if successfully integrated, Zenabis' business may prove costly to operate and result in unexpected expenses and inefficiencies. Although HEXO expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow it to offset integration-related costs over time, this net benefit may not be achieved in the near term, or at all.

The completion of the Zenabis Acquisition and the integration of Zenabis into the Company's operations could cause the attention of the Company's management to be diverted from the day-to-day operations. These disruptions could be exacerbated by a delay in the completion of the Zenabis Acquisition and could have an adverse effect on the business, operating results or prospects of the Company regardless of whether the Zenabis Acquisition is ultimately completed.

The consideration payable by us in connection with the Zenabis Acquisition will be satisfied by the issuance of Common Shares based on the Exchange Ratio. Consequently, holders of our Common Shares will incur dilution as a result of the Zenabis Acquisition.
