See “Plan of Distribution”.

The Company filed a prospectus supplement dated May 27, 2022 to its Base Prospectus with the securities commission or similar regulatory authority in each of the provinces of Canada, except Québec, and in connection therewith a prospectus supplement dated May 27, 2022 to its registration statement on Form F-10 with the United States Securities and Exchange Commission (the “SEC”) relating to the offering (the “Unit Offering”) by the Company to the public in Canada and the United States of units (“Units”), each Unit consisting of one common share of the Company (a “Unit Share”) and one Warrant. Each Warrant will entitle the holder thereof to purchase one Warrant Share at an exercise price of U.S.$3.20 per Warrant Share at any time until 5:00 p.m. (Toronto time) on the date (the “Expiry Date”) that is 36 months from the closing of the Unit Offering, subject to adjustment in accordance with the terms of the Warrant Indenture. The exercise price of the Warrants was determined by negotiation between the Company and a syndicate of underwriters for the Unit Offering (the “Underwriters”).

The Company has applied to list the Warrant Shares on the TSX and the Nasdaq. The TSX has conditionally approved the listing of the Warrant Shares issuable on exercise of the Warrants on the TSX. Listing is subject to the Company fulfilling all of the listing requirements of the TSX and the Nasdaq.

This Prospectus Supplement is filed pursuant to (i) the Base Prospectus filed in all of the provinces of Canada except Québec, and (ii) a base shelf prospectus filed as part of a registration statement on Form F-10 under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”), which became effective on March 30, 2021 upon filing with the SEC (the “Registration Statement”).

This Prospectus Supplement should be read in conjunction with, and may not be delivered or utilized without, the Base Prospectus.

No Underwriter has been involved in the preparation of, or has performed any review of, this Prospectus Supplement or the accompanying Base Prospectus.

The Company filed the Base Prospectus with the securities commissions in all Canadian provinces other than Québec (the “Canadian Qualifying Jurisdictions”) in order to qualify the offering of the securities described in the Base Prospectus in accordance with National Instrument 44-102 Shelf Distributions.

The Base Prospectus also forms part of the Registration Statement that we filed with the SEC under the U.S. Securities Act utilizing the MJDS. The Registration Statement became effective upon filing under the U.S. Securities Act on March 30, 2021. The Registration Statement incorporates the Base Prospectus with certain modifications and deletions permitted by Form F-10. This Prospectus Supplement is being filed by the Company with the SEC in accordance with the instructions to Form F-10.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Prospectus Supplement, the accompanying Base Prospectus and the documents incorporated by reference herein and therein, contain forward-looking statements and forward-looking information (collectively, “forward-looking statements”) which may not be based on historical fact. These forward-looking statements are made as of the date of this Prospectus Supplement, the accompanying Base Prospectus or the applicable document incorporated by reference herein or therein, and the Company does not intend, and does not assume any obligation, to update these forward-looking statements, except as required under applicable securities legislation. Forward-looking statements relate to future events or future performance and reflect Company management’s expectations or beliefs regarding future events. In certain cases, forward-looking statements can be identified by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved” or the negative of these terms or comparable terminology. In this document, certain forward-looking statements are identified by words including “may”, “future”, “expected”, “intends” and “estimates”. By their very nature forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. The Company provides no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Forward-looking statements in this Prospectus Supplement and the documents incorporated by reference include, but are not limited to, statements with respect to:

S-3

The above and other aspects of the Company’s anticipated future operations are forward-looking in nature and, as a result, are subject to certain risks and uncertainties. Such forward-looking statements are estimates reflecting the Company’s best judgment based upon current information and involve a number of risks and uncertainties, and there can be no assurance that other factors will not affect the accuracy of such forward-looking statements. These risks include, but are not limited to: the Company has a limited operating history and there is no assurance the Company will be able to achieve or maintain profitability; the Company operates in a highly regulated business and any failure or significant delay in obtaining applicable regulatory approvals could adversely affect its ability to conduct its business; the Company’s Canadian licenses are reliant on its established sites; the failure to maintain its licenses and remain in compliance with regulations could adversely affect the Company’s ability to conduct business; a change in the laws, regulations, and guidelines that impact the business may cause adverse effects on the Company’s operations; the Company competes for market share with a number of competitors and expects even more competitors to enter our market, and many of the Company’s current and future competitors may have longer operating histories, more financial resources, and lower costs than the Company; that management’s estimates of consumer demand in Canada and in jurisdictions where the Company exports are accurate; expectations of future results and expenses; management’s estimation that the Company will be able to maintain current SG&A expenditure levels and the SG&A will grow only in proportion to revenue growth, the yield from cannabis growing operations, product demand, changes in prices of required commodities; the selling prices and the cost of cannabis production may vary based on a number of factors outside of the Company’s control; the Company may not be able to realize our growth targets; the continuance of our contractual relations with provincial and territorial governments upon which much of the Company’s business depends cannot be guaranteed; the Company’s continued growth and ongoing operations may require additional financing, which may not be available on acceptable terms or at all; any default under the Company’s existing debt that is not waived by the applicable lenders could materially adversely impact the Company’s results of operations and financial results and may have a material adverse effect on the trading price of the Company’s Common Shares; the Company may not be able to successfully develop new products or find a market for their sale; the Company may not have supply continuity given the Company’s asset rationalization initiative; as the cannabis market continues to mature, the Company’s products may become obsolete, less competitive, or less marketable; restrictions on branding and advertising may negatively impact the Company’s ability to attract and retain customers; the cannabis business may be subject to unfavorable publicity or consumer perception, which may adversely affect the market for cannabis products generally and the Company’s products specifically; third

Readers are cautioned that the foregoing list of risk factors is not exhaustive, and it is recommended that prospective investors consult the more complete discussion of risks and uncertainties facing the Company included in this Prospectus Supplement and the accompanying Base Prospectus under the heading “Risk Factors”, as well as those set out in our 2021 AIF under the heading “Risk Factors” and in our 2021 Annual MD&A and Interim MD&A, each of which documents are incorporated by reference into this Prospectus Supplement. Readers are urged to consider the risks, uncertainties and assumptions carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on such information.

Should one or more of these risks or uncertainties materialize, or should underlying factors or assumptions prove incorrect, actual results may vary materially from those described in forward looking statements. Material factors or assumptions involved in developing forward-looking statements include, without limitation, publicly available information from governmental sources as well as from market research and industry analysis and on assumptions based on data and knowledge of the cannabis industry which the Company believes to be reasonable.

Although the Company believes that the expectations conveyed by the forward-looking statements are reasonable based on the information available to the Company on the date hereof, no assurance can be given as to future results, approvals or achievements. Forward-looking statements contained in this Prospectus Supplement, the accompanying Base Prospectus and in the documents incorporated by reference herein and therein are expressly

S-5

qualified by this cautionary statement. The Company disclaims any duty to update any of the forward-looking statements after the date of this Prospectus Supplement except as otherwise required by applicable law.

NOTE TO UNITED STATES READERS REGARDING DIFFERENCES

BETWEEN UNITED STATES AND CANADIAN FINANCIAL REPORTING PRACTICES

We prepare our financial statements in accordance with IFRS, as issued by the IASB, which differs from U.S. generally accepted accounting principles (“U.S. GAAP”). Accordingly, our financial statements and other financial information included or incorporated by reference in this Prospectus Supplement and the accompanying Base Prospectus may not be comparable to financial statements of United States companies prepared in accordance with U.S. GAAP.

NON-IFRS MEASURES

The information presented in this Prospectus Supplement and the accompanying Base Prospectus, including certain documents incorporated by reference herein and therein, may include non-IFRS measures that are used by us as indicators of financial performance. These financial measures do not have standardized meanings prescribed under IFRS and our computation may differ from similarly-named computations as reported by other entities and, accordingly, may not be comparable. These financial measures should not be considered as an alternative to, or more meaningful than, measures of financial performance as determined in accordance with IFRS as an indicator of performance. The Company believes these measures may be useful supplemental information to assist investors in assessing our operational performance and our ability to generate cash through operations. The non-IFRS measures also provide investors with insight into our decision making as we use these non-IFRS measures to make financial, strategic and operating decisions.

Because non-IFRS measures do not have a standardized meaning and may differ from similarly-named computations as reported by other entities, securities regulations require that non-IFRS measures be clearly defined and qualified, reconciled with their nearest IFRS measure and given no more prominence than the closest IFRS measure. If non-IFRS measures are included in documents incorporated by reference herein, information regarding these non-IFRS measures are presented in the sections dealing with these financial measures in such documents.

Non-IFRS measures are not audited. These non-IFRS measures have important limitations as analytical tools and investors are cautioned not to consider them in isolation or place undue reliance on ratios or percentages calculated using these non-IFRS measures.

CURRENCY PRESENTATION AND EXCHANGE RATE INFORMATION

Unless stated otherwise or as the context otherwise requires, all references to dollar amounts in this Prospectus Supplement are references to Canadian dollars. References to “C$” are to Canadian dollars and references to “U.S. dollars” or “U.S.$” are to United States dollars.

Except as otherwise noted in our 2021 AIF and the Company’s financial statements and related management’s discussion and analysis of financial condition and results of operations of the Company that are incorporated by reference into this Prospectus Supplement, the financial information contained in such documents is expressed in Canadian dollars.

Recent Developments

Global COVID-19 Pandemic

For the nine months ended March 31, 2022, the COVID-19 pandemic has impacted revenue in the Canadian consumer market, particularly in Ontario, as governments have restricted retail access to curbside pickup at certain times during the COVID-19 pandemic, and both governments and customers have changed their purchasing patterns to reflect the slow-down in the market. As at the date of this Prospectus Supplement, the production and sale of medical and consumer cannabis have been recognized as essential services across Canada and Europe. All of the Company’s facilities in Canada and internationally continue to be operational and we continue to work closely with local, national and international government authorities to ensure that we are following the required protocols and guidelines related to COVID-19 within each region. Although there have not been any significant impacts to the Company’s operations to date, the Company cannot provide assurance that there will not be disruptions to its operations in the future. Refer to the “Risk Factors” section in the 2021 Annual MD&A and the Interim MD&A for further discussion on the potential impacts of COVID-19.

USE OF PROCEEDS

We will receive all proceeds of the full issue price of U.S.$3.20 per Warrant Share upon issuance of the Warrant Shares upon any exercise of the Warrants from time to time. Assuming that all of the Warrants are exercised prior to 5:00 p.m. (Toronto time) on the Expiry Date for cash, that no adjustment based on anti-dilution provisions contained in the Warrant Indenture has taken place and that the Over-Allotment Option is exercised in full, the proceeds to the Company will be U.S.$225,308,000. There is no assurance as to how many Warrants will be exercised, if any. Accordingly, there is no assurance as to how many Warrant Shares will be issued pursuant to this Prospectus Supplement, if any, or the proceeds of such offering.

It is currently anticipated that the Company will use any proceeds from the Offering for general corporate purposes.

Although we intend to use the proceeds from the Offering as set forth above, the actual allocation of the net proceeds may vary depending on future developments, at the discretion of our board of directors and management. See “Risk Factors – The Company has discretion with respect to the use of proceeds from this Offering”.

During the fiscal year ended June 30, 2021 and the third quarter ended March 31, 2022, the Company had negative cash flow from operating activities. Although the Company anticipates it will be able to generate positive cash flow from operating activities in the future, the Company cannot guarantee it will have positive cash flow from operating activities in any future period. To the extent that the Company has negative operating cash flow in any future period, current working capital and certain of the proceeds from the Offering may be used to fund such negative cash flow from operating activities. See “Risk Factors – Negative Cash Flow from Operations”.

CONSOLIDATED CAPITALIZATION

As of May 30, 2022, the Company had 227,349,833 Common Shares issued and outstanding. Except as described below, there have been no material changes in our share and debt capital, on a consolidated basis, since

The following summary of certain anticipated provisions of the Warrant Indenture does not purport to be complete and is subject in its entirety to the detailed provisions of the executed Warrant Indenture. Reference is made to the Warrant Indenture for the full text of the attributes of the Warrants, which will be filed on SEDAR under the issuer profile of the Company at www.sedar.com and with the SEC at www.sec.gov. A register of holders of Warrants will be maintained at the principal offices of the Warrant Agent in Vancouver, British Columbia. The holders of Warrants will not, as such, have any voting right or other right attached to the Warrant Shares until and unless the Warrants are duly exercised as provided for in the Warrant Indenture.

The Warrant Indenture will provide that the number of Warrant Shares which may be acquired by a holder of Warrants upon the exercise thereof will be subject to anti-dilution provisions governed by the Warrant Indenture, including provisions for the appropriate adjustment of the class, number and price of the securities issuable under the Warrant Indenture upon the occurrence of certain events including:

The Warrant Indenture will also include provisions for the appropriate adjustment of the class, number and price of the securities issuable under the Warrant Indenture upon the occurrence of the following additional events:

S-14

The Warrant Indenture will provide that: (i) no adjustment to the exercise price for the Warrants will be required to be made unless such adjustment would result in a change of at least 1% in the exercise price for the Warrants; and (ii) no adjustment to the number of Warrant Shares issuable upon exercise of the Warrants will be required to be made unless such adjustment would result in a change of at least one one-hundredth of a Warrant Share.

The Company will covenant in the Warrant Indenture, during the period in which the Warrants are exercisable, to give notice to holders of Warrants of certain stated events, including events that would result in an adjustment to the exercise price for the Warrants or the number of Warrant Shares issuable upon exercise of the Warrants, a prescribed number of days prior to the record date or effective date, as the case may be, of such event.

The Warrant Indenture will provide that, from time to time, the Warrant Agent and the Company, without the consent of the holders of Warrants, will be able to amend or supplement the Warrant Indenture for certain purposes, including rectifying any ambiguities, defective provisions, clerical omissions or mistakes, or other errors contained in the Warrant Indenture or in any deed or indenture supplemental or ancillary to the Warrant Indenture, provided that, in the opinion of the Warrant Agent, relying on legal counsel, the rights of the holders of Warrants, as a group, are not prejudiced thereby. Subject to the voting rights set forth in the Warrant Indenture, the rights of holders of the Warrants may, in certain circumstances, be modified by way of an extraordinary resolution passed by the affirmative vote of the holders of not less than 66²⁄₃% of the aggregate number of all the then outstanding Warrants at a meeting duly called and held in accordance with the terms of the Warrant Indenture at which there are present in person or by proxy at least two holders representing at least 20% of the aggregate number of all the then outstanding Warrants.

The Warrant Indenture will also provide that in the event of an extraordinary transaction, as described in the Warrant Indenture and generally including any merger, arrangement or amalgamation of the Company with or into another entity, sale of all or substantially all of the Company’s assets, tender offer or exchange offer, or reclassification of the Common Shares, the holders of the Warrants will generally be entitled to receive upon exercise of the Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Warrants immediately prior to such extraordinary transaction.

The Warrant Indenture will include certain beneficial ownership limitations under which Warrants will not be exercisable to the extent that, after giving effect to the issuance of the Warrant Shares issuable upon such exercise of the Warrants, the holder, together with its affiliates and other persons acting as a group with the holder or any of its affiliates, would beneficially own in excess of 4.99% of the number of Common Shares outstanding immediately after giving effect to such issuance. Such beneficial ownership limitation may be increased or decreased by the holder upon notice to the Company, to a maximum of 9.99%. Except as provided in the Warrant Indenture, beneficial ownership will be calculated in accordance with Section 13(d) of the U.S. Exchange Act and the rules and regulations promulgated thereunder. To the extent the beneficial ownership limitations apply, the determination of whether a Warrant is exercisable and of which portion of a Warrant is exercisable shall be in the sole discretion and at the sole responsibility of the holder, and the submission of an exercise notice in respect of any Warrants shall be deemed to be the holder’s determination of whether the Warrants are exercisable, and neither the Warrant Agent nor the Company will have any obligation to verify or confirm the accuracy of such determination.

The Company will use commercially reasonable best efforts to maintain a registration statement effective until the earlier of the Expiry Date or such time as no Warrants remain outstanding (provided, however, that nothing

S-15

shall prevent the Company’s amalgamation, arrangement, merger or sale, including any take-over bid, and any associated delisting or deregistration or ceasing to be a reporting issuer, provided that, so long as the Warrants are still outstanding and represent a right to acquire securities of the acquiring company, the acquiring company shall assume the Company’s obligations under the Warrant Indenture), which could require the additional filing of a new registration statement and/or base shelf prospectus and prospectus supplement if the current Prospectus is no longer usable. If, at any time prior to the Expiry Date, the Company determines that no registration statement filed with the SEC is effective, or that its use is suspended, no holder of Warrants will be permitted to exercise Warrants unless an exemption from the registration requirements of the U.S. Securities Act and applicable state securities laws is available, and the holders of Warrants will receive a notice of this determination, together with written confirmation that the Warrants may, until the earlier of (x) a registration statement becoming effective or ceasing to be suspended and any prospectus supplement necessary in relation thereto having been filed and (y) the Expiry Date, if the Current Market Price (as defined in the Warrant Indenture) of the Common Shares exceeds the exercise price for the Warrants, also be exercised by means of a “cashless exercise” in which the holder of Warrants will be entitled to receive a certificate for a number of Warrant Shares determined on the basis of the excess of the current market price over the exercise price for the Warrants.

The principal transfer office of the Warrant Agent in Vancouver, British Columbia is the location at which Warrants may be surrendered for exercise or transfer.

The Company filed a prospectus supplement dated May 27, 2022 to its Base Prospectus with the securities commission or similar regulatory authority in each of the provinces of Canada, except Québec, and in connection therewith a prospectus supplement dated May 27, 2022 to the Registration Statement with the SEC relating to the offering by the Company to the public in Canada and the United States of Units. In connection with the Unit Offering, the Company has qualified the distribution by the Company of up to 61,225,000 Units at a price of U.S.$2.45 per Unit pursuant to the terms of the underwriting agreement entered into between the Company and the Underwriters on May 27, 2022 (the “Underwriting Agreement”). The Unit Offering is expected to be completed on or about May 31, 2022. The exercise price of the Warrants was determined by negotiation between the Company and the Underwriters.

The Company granted the Underwriters an option (the “Over-Allotment Option”) to purchase up to an additional 9,183,750 Units (the “Over-Allotment Units”), comprised of 9,183,750 additional Unit Shares (“Over-Allotment Unit Shares”) and 9,183,750 additional Warrants (“Over-Allotment Warrants” and, together with the Over-Allotment Units and Over-Allotment Unit Shares, the “Over-Allotment Securities”). The Over-Allotment Option is exercisable in whole or in part at any time up to 30 days after the date of closing of the Unit Offering. The Over-Allotment Option may be exercised by the Underwriters in respect of: (i) Over-Allotment Units at a price of U.S.$2.45 per Over-Allotment Unit; (ii) Over-Allotment Unit Shares at a price of U.S.$2.21 per Over-Allotment Unit Share; (iii) Over-Allotment Warrants at a price of U.S.$0.24 per Over-Allotment Warrant; or (iv) any combination of the Over-Allotment Securities, so long as the aggregate number of Over-Allotment Unit Shares and Over-Allotment Warrants which may be issued under the Over-Allotment Option does not exceed 9,183,750 Over-Allotment Unit Shares and 9,183,750 Over-Allotment Warrants.

It is a condition of closing of the Unit Offering that the Company has filed with the SEC this Prospectus Supplement registering the offering of the Warrant Shares issuable from time to time upon the exercise of the Warrants.

This Prospectus Supplement registers the offering of the securities to which it relates under the U.S. Securities Act in accordance with the MJDS. This Prospectus Supplement does not qualify in any of the provinces or territories of Canada the distribution of the Warrant Shares to which it relates.

The Warrant Shares to which this Prospectus Supplement relates will be sold directly by the Company to holders of Warrants upon any exercise of such Warrants. No underwriters, dealers or agents will be involved in these sales.

S-16

The Common Shares are listed on the TSX and on the Nasdaq under the symbol “ACB” and on the FSE under the symbol “21P”. The Company has applied to list the Warrant Shares on the TSX and the Nasdaq. The TSX has conditionally approved the listing of the Warrant Shares issuable on exercise of the Warrants on the TSX. Listing is subject to the Company fulfilling all of the listing requirements of the TSX and the Nasdaq.

There is no assurance as to how many of the Warrants will be exercised, and accordingly, there is no assurance as to how many Warrant Shares will be issued pursuant to this Prospectus Supplement, if any. No party has any obligation to purchase any Warrant Shares qualified by this Prospectus Supplement.

No fractional Common Shares will be issuable upon the exercise of any Warrants, and no cash or other consideration will be paid in lieu of fractional Common Shares.

RISK FACTORS

An investment in the Warrant Shares is highly speculative and subject to a number of known and unknown risks. Only those persons who can bear the risk of loss of their investment should purchase the Warrant Shares. Investors should consider carefully the risk factors set out herein and contained in and incorporated by reference in the Base Prospectus. Discussions of certain risks affecting us in connection with our business are set out under the heading “Risk Factors” in the accompanying Base Prospectus as well as in the documents incorporated by reference therein and herein, including, specifically, under the heading “Risk Factors” in the 2021 AIF. Any of the matters highlighted in these risk factors could have a material adverse effect on our business, results of operations and financial conditions, causing an investor to lose all, or part of, its, his or her investment.

The Company has discretion with respect to the use of proceeds from this Offering.

Management will have broad discretion with respect to the use of the proceeds from this Offering, if any, and investors will be relying on the judgment of management regarding the application of these proceeds. At the date of this Prospectus Supplement, the Company intends to use the proceeds from this Offering as described under the heading “Use of Proceeds”. However, the Company’s needs may change as its business and the industry the Company addresses evolve. As a result, the proceeds to be received in this Offering may be used in a manner significantly different from the Company’s current expectations. The failure by management to apply these funds effectively could have a material adverse effect on the Company’s business.

Negative Cash Flow from Operations

The Company had negative operating cash flows for the fiscal year ended June 30, 2021 and the third quarter ended March 31, 2022. Although the Company anticipates it will be able to generate positive cash flow from operating activities in the future, the Company cannot guarantee it will have positive cash flow from operating activities in any future period. To the extent that the Company has negative operating cash flow in any future period, certain of the proceeds from the Offering may be used to fund such negative cash flow from operating activities. See “Use of Proceeds”.

Future sales or issuances of Common Shares could decrease the value of any existing Common Shares or Warrants, dilute voting power of holders of Common Shares and reduce the Company’s earnings per share.

Future issuances of equity securities by the Company could decrease the value of any existing Common Shares and Warrants, dilute voting power of holders of Common Shares, reduce the Company’s earnings per share and make future sales of the Company’s equity securities more difficult. With any additional sale or issuance of equity securities, holders of Common Shares will suffer dilution of their voting power and may experience dilution in the Company’s earnings per share. Sales of Common Shares by shareholders might also make it more difficult for the Company to sell equity securities at a time and price that it deems appropriate.

S-17

The Company may issue additional equity securities (including through the sale of securities convertible into, or exchangeable for, Common Shares) under the Company’s current equity incentive plans. In addition, the Company may issue Common Shares to finance its operations or future acquisitions. The Company cannot predict the size of future sales and issuances of debt or equity securities or the effect, if any, that future sales and issuances of equity securities will have on the market price of the Common Shares and Warrants.

Sales or issuances of a substantial number of equity securities, or the perception that such sales could occur, may adversely affect prevailing market prices for the Common Shares and the Warrants.

The Common Share price has experienced volatility and may be subject to fluctuation in the future based on market conditions, which could also affect the market price of the Warrants.

The market prices for the securities of cannabis companies, including the Company, have historically been, and may in the future be, subject to large fluctuations. The market has from time to time experienced significant price and volume fluctuations that are unrelated to the operating performance of any particular company. In addition, because of the nature of the Company’s business, certain factors such as announcements and the public’s reaction, the Company’s operating performance and the performance of competitors and other similar companies, government regulations, changes in earnings estimates or recommendations by research analysts who track the Company’s securities or securities of other companies in the cannabis industry, general market conditions, announcements relating to litigation, the arrival or departure of key personnel and the factors listed under the heading “Cautionary Note Regarding Forward-Looking Statements” can have an adverse impact on the market price of the Common Shares and Warrants.

Any negative change in the public’s perception of the Company’s prospects could cause the price of the Company’s securities, including the price of the Common Shares and Warrants, to decrease dramatically. Furthermore, any negative change in the public’s perception of the prospects of cannabis companies in general could depress the price of the Company’s securities, including the price of the Common Shares and Warrants, regardless of the Company’s results. Following declines in the market price of a corporation’s securities, securities class-action litigation could be instituted. Litigation of this type, if instituted, could result in substantial costs and a diversion of management’s attention and resources.

No public market for Warrants

Although the Company has applied to list the Warrants on the TSX, there can be no assurance that such listing will be obtained. There is currently no market through which the Warrants may be sold and purchasers may not be able to resell the Warrants. There can be no assurance that a secondary market for trading in the Warrants will develop or that any secondary market which does develop will continue and if it does develop, that it will be active. This may affect the pricing of the Warrants in the secondary market and the transparency and availability of trading prices. Without an active market, the liquidity of the Warrants will be limited and you may be unable to sell the Warrants at the prices desired or at all. The Warrants have an exercise price of U.S.$3.20 per Warrant Share (subject to adjustment in certain circumstances) and can be exercised at any time prior to the Expiry Date. In the event the market price of the Common Shares does not exceed the exercise price of the Warrants during the period when the Warrants are exercisable, the Warrants may not have any value. Holders of the Warrants will have no rights as shareholders of the Company until they exercise the Warrants in accordance with their terms. Upon exercise of the Warrants, holders of the Warrant Shares deliverable on the exercise of such Warrants will be entitled to exercise the rights of a shareholder in respect of such Warrant Shares only in respect of matters for which the record date occurs after the exercise date. See “Description of Securities Being Distributed – Warrants”.

Return on Investment Risk

There is no guarantee that an investment in Warrant Shares will earn any positive return in the short or long term. An investment in the Warrant Shares involves a high degree of risk and should be undertaken only by investors

S-18

whose financial resources are sufficient to enable them to assume such risks, who have no need for immediate liquidity in their investment and who have the financial capacity to absorb a loss of some or all of their investment.

We may be a passive foreign investment company, or “PFIC”, which could result in adverse U.S. federal income tax consequences to U.S. investors.

The Company has not made a formal determination as to whether it was a PFIC for the year ended June 30, 2021. If we are a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder (as defined in the section of this Prospectus Supplement captioned “Material U.S. Federal Income Tax Considerations”) of our Common Shares or Warrants, the U.S. Holder may be subject to certain adverse U.S. federal income tax consequences and may be subject to additional reporting requirements. The Company intends to make a formal determination concerning its PFIC status with respect to its June 30, 2021 tax year, and also promptly following the close of the current tax year, to communicate that determination to investors and will endeavor to provide information required by investors for a “qualified electing fund” or “QEF” if the Company determines that it is a PFIC. See “Material U.S. Federal Income Tax Considerations – Passive Foreign Investment Company Considerations”.

ELIGIBILITY FOR INVESTMENT

In the opinion of Stikeman Elliott LLP, counsel to the Company, based on the current provisions of the Income Tax Act (Canada) and the regulations thereunder (collectively, the “Tax Act”), and the proposals to amend the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, the Warrant Shares will be “qualified investments” under the Tax Act at a particular time for a trust governed by a registered retirement savings plan (“RRSP”), a registered retirement income fund (“RRIF”), a registered education savings plan (“RESP”), a registered disability savings plan (“RDSP”), a tax-free savings account (“TFSA”) (each, a “Registered Plan”) and a deferred profit sharing plan (“DPSP”), provided that, at that time, either the Warrant Shares are listed on a “designated stock exchange” as defined in the Tax Act (which currently includes the TSX) or the Company is otherwise a “public corporation” (other than a mortgage investment corporation) as defined in the Tax Act.

Notwithstanding that the Warrant Shares may be “qualified investments” for a Registered Plan as referenced above, if the Warrant Shares are a “prohibited investment” within the meaning of the Tax Act for a Registered Plan, the annuitant of the RRSP or RRIF, the holder of the RDSP or TFSA, or the subscriber of the RESP, as the case may be, will be subject to penalty taxes as set out in the Tax Act. The Warrant Shares will generally not be a “prohibited investment” for a Registered Plan if the annuitant, holder or subscriber, as applicable, (a) deals at “arm’s length” with the Company for the purposes of the Tax Act, and (b) does not have a “significant interest” (as defined for purposes of the prohibited investment rules in the Tax Act) in the Company. In addition, the Warrant Shares will not be a prohibited investment if such securities are “excluded property” (as defined in the Tax Act for purposes of the prohibited investment rules) for a Registered Plan.

Prospective purchasers who intend to invest within a Registered Plan or DPSP should consult their own tax advisors in advance with respect to the application of these and other tax rules in their particular circumstances.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

General

The following is a general summary, as of the date hereof, of the principal Canadian federal income tax considerations under the Tax Act generally applicable to a holder who acquires, as beneficial owner, Warrant

S-19

Shares upon exercise of the Warrants, and who, for purposes of the Tax Act and at all relevant times, (i) holds Warrant Shares and Warrants as capital property, (ii) deals at arm’s length with the Company and the Underwriters, and (iii) is not affiliated with the Company or the Underwriters. A holder who meets all of the foregoing requirements is referred to as a “Holder” herein, and this summary only addresses such Holders. Generally, the Warrant Shares and Warrants will be considered to be capital property to a Holder unless they are held or acquired in the course of carrying on a business or as part of an adventure or concern in the nature of trade.

This summary is not applicable to (i) a Holder that is a “financial institution”, as defined in the Tax Act for purposes of the mark-to-market rules in the Tax Act, (ii) a Holder that is a “specified financial institution”, as defined in the Tax Act, (iii) a Holder an interest in which is a “tax shelter investment” as defined in the Tax Act, (iv) a Holder that makes or has made a functional currency reporting election for purposes of the Tax Act, or (v) a Holder that has entered into or will enter into a “derivative forward agreement”, a “synthetic disposition arrangement” or a “dividend rental arrangement”, each as defined in the Tax Act, with respect to the Warrants or Warrant Shares. In addition, this summary does not address the deductibility of interest by a Holder who has borrowed money or otherwise incurred debt in connection with the acquisition of Warrant Shares or Warrants. All such Holders should consult their own tax advisors.

Additional considerations, not discussed herein, may be applicable to a Holder that is a corporation resident in Canada and is, or becomes, or does not deal at arm’s length with a corporation resident in Canada that is, or becomes, controlled by a non-resident person, or a group of non-resident persons not dealing with each other at arm’s length, for purposes of the “foreign affiliate dumping” rules in section 212.3 of the Tax Act. Such Holders should consult their own tax advisors with respect to the consequences of acquiring the Warrant Shares.

This summary is based on the provisions of the Tax Act in force as of the date hereof, all specific proposals to amend the Tax Act that have been publicly and officially announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Proposed Amendments”) and our understanding of the current administrative policies and assessing practices of the Canada Revenue Agency (the “CRA”) published in writing prior to the date hereof. This summary assumes the Proposed Amendments will be enacted in the form proposed. However, no assurance can be given that the Proposed Amendments will be enacted in their current form, or at all. This summary is not exhaustive of all possible Canadian federal income tax considerations and, except for the Proposed Amendments, does not take into account or anticipate any changes in the law or any changes in the CRA’s administrative and assessing policies or practices, whether by legislative, governmental or judicial action or decision, nor does it take into account or anticipate any other federal or any provincial, territorial or foreign tax considerations, which may differ significantly from those discussed herein. Any particular Holder should consult their own tax advisors with respect to provincial, territorial or foreign tax considerations. This summary is not intended to be, nor should it be construed to be, legal or tax advice to any particular Holder, and no representations with respect to the income tax consequences to any Holder are made. Consequently, Holders should consult their own tax advisors with respect to the tax consequences applicable to them, having regard to their own particular circumstances. The discussion below is qualified accordingly.

Currency Conversion

Holders are required to compute their income and gains for Canadian tax purposes in Canadian dollars. Therefore, for purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of the Warrant Shares must be converted into Canadian dollars based on the exchange rate quoted by the Bank of Canada for the date such amounts arise or such other rate of exchange as is acceptable to the CRA.

Allocation of Cost

Holders will be required to allocate the aggregate cost of a Unit between the Unit Share and the Warrant on a reasonable basis in order to determine their respective costs for purposes of the Tax Act. The Company intends to

S-20

allocate as consideration for their issue U.S.$2.21 to each Unit Share and U.S.$0.24 to each Warrant acquired as part of a Unit. The Company believes that such allocation is reasonable but such allocation will not be binding on the CRA or a Holder, and no valuation or related opinion has been sought or obtained in this regard.

Exercise of Warrants

No gain or loss will be realized by a Holder on the exercise of a Warrant to acquire a Warrant Share. When a Warrant is exercised, the Holder’s cost of the Warrant Share acquired thereby will be equal to the aggregate of the Holder’s adjusted cost base of such Warrant and the exercise price paid for the Warrant Share. The Holder’s adjusted cost base of the Warrant Share so acquired will be determined by averaging the cost of the Warrant Share with the adjusted cost base to the Holder of all Common Shares of the Company held as capital property immediately before the acquisition of the Warrant Share.

Taxation of Resident Holders

The following portion of this summary applies to Holders (as defined above) who, for the purposes of the Tax Act, are or are deemed to be resident in Canada at all relevant times (herein, “Resident Holders”) and this portion of the summary only addresses such Resident Holders. Certain Resident Holders whose Warrant Shares might not otherwise constitute capital property may make, in certain circumstances, an irrevocable election permitted by subsection 39(4) of the Tax Act to deem such 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 with respect to whether the election is available and advisable in their particular circumstances.

Taxation of Dividends

A Resident Holder will be required to include in computing income for a taxation year any dividends received, or deemed to be received, in the year by the Resident Holder on the Warrant Shares. 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 under the Tax Act to taxable dividends received from taxable Canadian corporations, including the enhanced gross-up and dividend tax credit provisions where the Company designates the dividend as an “eligible dividend” in accordance with the provisions of the Tax Act. There may be restrictions on the ability of the Company to designate any dividend as an “eligible dividend”, and the Company has made no commitments in this regard.

A dividend received or deemed to be received by a Resident Holder that is a corporation must be included in computing its income for a taxation year but will generally be deductible in computing the corporation’s 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 disposition or a capital gain. A corporation that is a “private corporation” (as defined in the Tax Act) or any other corporation controlled (whether because of a beneficial interest in one or more trusts or otherwise) by or for the benefit of an individual (other than a trust) or a related group of individuals (other than trusts), generally will be liable to pay an additional tax (refundable under certain circumstances) under Part IV of the Tax Act on dividends received or deemed to be received on the Warrant Shares in a year to the extent such dividends are deductible in computing taxable income for the year.

Disposition of Warrant Shares

A Resident Holder who disposes or is deemed to dispose of a Warrant Share generally will realize a capital gain (or capital loss) equal to the amount, if any, by which the proceeds of disposition, net of any reasonable costs of disposition, are greater (or are less) than the adjusted cost base to the Resident Holder of such Warrant Shares immediately before the disposition or deemed disposition. The taxation of capital gains and losses is generally described below under the heading “Capital Gains and Capital Losses”.

S-21

Capital Gains and Capital Losses

Generally, a Resident Holder is required to include in computing income for a taxation year one-half of the amount of any capital gain (a “taxable capital gain”) realized by the Resident Holder in such taxation year. Subject to and in accordance with the rules contained in 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 particular taxation year against taxable capital gains realized by the Resident Holder in the year. Allowable capital losses in excess of taxable capital gains for the taxation year of disposition may, in general terms, be carried back and deducted in any of the three preceding taxation years, or in any subsequent year, against net taxable capital gains realized in such years, to the extent and under the circumstances described in the Tax Act.

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

Refundable Tax

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 an additional tax (refundable in certain circumstances) on certain “aggregate investment income”, including taxable capital gains and dividends received or deemed to be received on a Unit Share or Warrant Share to the extent that such dividends are not deductible in computing the Resident Holder’s taxable income for the taxation year. Proposed Amendments announced by the Minister of Finance (Canada) on April 7, 2022 are intended to extend this additional tax and refund mechanism in respect of aggregate investment income to “substantive CCPCs” as defined in the Proposed Amendments announced on April 7, 2022. The complete legislation for such Proposed Amendments has yet to be released. Resident Holders should consult their own tax advisors with regard to this additional tax and refund mechanism.

Alternative Minimum Tax

Capital gains realized and dividends received or deemed to be received by a Resident Holder that is an individual or a trust, other than certain specified trusts, may give rise to alternative minimum tax under the Tax Act. Resident Holders should consult their own tax advisors in this regard.

Taxation of Non-Resident Holders

The following portion of this summary is generally applicable to Holders (as defined above) who, for the purposes of the Tax Act and at all relevant times: (i) are not resident or deemed to be resident in Canada, and (ii) do not use or hold, and are not deemed to use or hold Warrants or Warrant Shares in carrying on a business in Canada. Holders who meet all of the foregoing requirements are referred to herein as “Non-Resident Holders”, and this portion of the summary only addresses such 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 business in Canada and elsewhere or an “authorized foreign bank” (as defined in the Tax Act). Such Non-Resident Holders should consult their own tax advisors.

Receipt of Dividends

Dividends paid or credited or deemed to be paid or credited to a Non-Resident Holder by the Company are generally subject to Canadian withholding tax at the rate of 25% of the gross amount of the dividend unless reduced by the terms of an applicable tax treaty between Canada and the Non-Resident Holder’s jurisdiction of

S-22

residence. Non-Resident Holders should consult their own tax advisors in this regard. For example, under the Canada-United States Tax Convention (1980) (the “Treaty”) as amended, 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 United States for purposes of the Treaty, fully entitled to benefits under the Treaty and is the beneficial owner of the dividend (a “U.S. Resident Holder”) is generally limited to 15% of the gross amount of the dividend (or 5% in the case of a U.S. Resident Holder that is a company beneficially owning at least 10% of the Company’s voting shares). Non-Resident Holders should consult their own tax advisors regarding the application of any applicable tax treaty to dividends based on their particular circumstances.

Disposition of Warrant 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 a Warrant Share unless such Warrant Share constitutes “taxable Canadian property” (as defined in the Tax Act) to the Non-Resident Holder at the time of disposition and the gain is not exempt from tax pursuant to the terms of an applicable tax treaty between Canada and the Non-Resident Holder’s jurisdiction of residence.

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

Non-Resident Holders who may hold Warrant Shares as taxable Canadian property should consult their own tax advisors.

THE ABOVE SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL CANADIAN TAX CONSIDERATIONS APPLICABLE TO HOLDERS WITH RESPECT TO THE OWNERSHIP, EXERCISE OR DISPOSITION OF THE WARRANT SHARES. ALL HOLDERS (INCLUDING NON-RESIDENT HOLDERS) SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE TAX CONSIDERATIONS APPLICABLE TO THEM IN THEIR PARTICULAR CIRCUMSTANCES.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of material U.S. federal income tax consequences of the acquisition, ownership, exercise, and disposition of the Warrant Shares that are applicable to a U.S. Holder, as defined below, that acquires the Warrant Shares pursuant to this Prospectus Supplement. This discussion is not a complete analysis or listing of all of the possible tax consequences of such transactions and does not address all tax considerations that might be relevant to particular holders in light of their personal circumstances or to persons that are subject to special tax rules. In particular, the information set forth below deals only with U.S. Holders that will hold Warrant Shares as capital assets for U.S. federal income tax purposes (generally, property held for investment) and that do not own 10 percent or more of the total combined voting power of all classes of Company stock

S-23

entitled to vote or 10 percent or more of the total value of shares of all classes of Company stock. In addition, this discussion of the U.S. federal income tax consequences does not address the tax treatment of special classes of U.S. Holders, such as: financial institutions; regulated investment companies; real estate investment trusts; tax-exempt entities; insurance companies; persons holding Warrants and the Warrant Shares as part of a hedging, integrated or conversion transaction, constructive sale or “straddle”; persons who acquired Warrants or Warrant Shares through the exercise or cancellation of employee stock options or otherwise as compensation for their services; U.S. expatriates; persons subject to the alternative minimum tax; persons that generally mark their securities to market for U.S. federal income tax purposes; dealers or traders in securities or currencies; or holders whose functional currency is not the U.S. dollar.

This discussion does not address estate and gift tax, any U.S. federal tax other than income tax, or tax consequences under any state, local or foreign laws.

For purposes of this section, a “U.S. Holder” is a beneficial owner of the Warrants and Warrant Shares that is: (1) an individual citizen of the United States or a resident alien of the United States as determined for U.S. federal income tax purposes; (2) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia; (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source; or (4) a trust (A) if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have authority to control all substantial decisions of the trust or (B) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If a partnership or other pass-through entity is a beneficial owner of the Warrant and Warrant Shares, the tax treatment of a partner or other owner will generally depend upon the status of the partner (or other owner) and the activities of the entity. A U.S. Holder that is a partner (or other owner) of a pass-through entity that acquires Warrants or Warrant Shares is urged to consult its own tax advisor regarding the tax consequences of acquiring, owning and disposing of Warrants or Warrant Shares.

The following discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the “Code”), existing and proposed U.S. Treasury regulations, U.S. judicial decisions and administrative pronouncements, all as in effect as of the date hereof. All of the preceding authorities are subject to change, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those discussed below. The Company has not requested, and will not request, a ruling from the IRS with respect to any of the U.S. federal income tax consequences described below, and as a result there can be no assurance that the IRS will not disagree with or challenge any of the conclusions described herein.

As discussed below, the Company has not made a formal determination as to whether it was a PFIC for the year ended June 30, 2021. This discussion assumes that the Company is not a PFIC, as discussed below under “Passive Foreign Investment Company Considerations”.

The following discussion is for general information only and is not intended to be, nor should it be construed to be, legal or tax advice to any holder or prospective holder of Warrants or Warrant Shares and no opinion or representation with respect to the U.S. federal income tax consequences to any such holder or prospective holder is made. Prospective purchasers are urged to consult their own tax advisors as to the particular consequences to them under U.S. federal, state and local, and applicable foreign, tax laws of the acquisition, ownership and disposition of Warrants or Warrant Shares.

Exercise, Disposition or Expiration of Warrants

Exercise of Warrants

A U.S. Holder generally should not recognize gain or loss on the exercise of a Warrant and related receipt of a Warrant Share. A U.S. Holder’s initial tax basis in the Warrant Share received on the exercise of a Warrant

S-24

should be equal to the sum of (a) such U.S. Holder’s tax basis in such Warrant plus (b) the exercise price paid by such U.S. Holder on the exercise of such Warrant. Subject to the discussion under “Passive Foreign Investment Company Considerations” below, a U.S. Holder’s holding period for the Warrant Share received on the exercise of a Warrant should generally begin on the date following the date of exercise of the Warrant, and should not include any period for which the U.S. Holder held the Warrant. The U.S. federal income tax treatment of a cashless exercise of a Warrant is uncertain. Each U.S. Holder should consult its own tax advisor regarding the proper treatment of any cashless exercise of a Warrant and the tax basis in, and the holding period for, the Warrant Share received on such exercise.

Ownership and Disposition of Warrant Shares

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

Distributions

Subject to the PFIC rules discussed below, the gross amount of any distribution made by the Company (without reduction for any Canadian income tax withheld from such distribution) will generally be subject to U.S. federal income tax as dividend income to the extent paid out of the Company’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Such amount will be includable in gross income by a U.S. Holder as ordinary income on the date that the U.S. Holder actually or constructively receives the distribution in accordance with its regular method of accounting for U.S. federal income tax purposes. The amount of any distribution made by the Company in property other than cash will be the fair market value of such property on the date of the distribution. Dividends paid by the Company will not be eligible for the dividends received deduction allowed to corporations.

Subject to applicable exceptions with respect to short-term and hedged positions, certain dividends received by non-corporate U.S. Holders from a “qualified foreign corporation” may be eligible for reduced rates of taxation. A qualified foreign corporation includes a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that the U.S. Treasury Department determines to be satisfactory for these purposes and that includes an exchange of information provision. The U.S. Treasury Department has determined that the income tax treaty between the United States and Canada meets these requirements, and the Company believes that it is eligible for the benefits of this treaty. A foreign corporation is also treated as a qualified foreign corporation with respect to dividends paid by that corporation on ordinary shares that are readily tradable on an established securities market in the United States. U.S. Treasury guidance indicates that the Company’s securities will be readily tradable on an established securities market in the United States; however, there can be no assurance that the Warrant Shares will be considered readily tradable on an established securities market in the United States in future years. Dividends received by U.S. investors from a foreign corporation that was a PFIC in either the taxable year of the distribution or the preceding taxable year will not constitute dividends eligible for the reduced rates of taxation described above. Instead, such dividends would be subject to tax at ordinary income rates and to additional rules described below under “Passive Foreign Investment Company Considerations”.

To the extent that a distribution exceeds the amount of the Company’s current and accumulated earnings and profits, as determined under U.S. federal income tax principles, it will be treated first as a tax-free return of capital, causing a reduction in the U.S. Holder’s adjusted tax basis in the Warrant Shares held by such U.S. Holder (thereby increasing the amount of gain, or decreasing the amount of loss, to be recognized by such U.S. Holder upon a subsequent disposition of the Warrant Shares), with any amount that exceeds the adjusted tax basis being treated as a capital gain recognized on a sale, exchange or other taxable disposition (as discussed below). However, the Company does not intend to maintain calculations of its earnings and profits in accordance with U.S. federal income tax principles, and a U.S. Holder should therefore assume that any distribution by the Company with respect to the Warrant Shares will be treated as dividends for U.S. federal income tax purposes.

S-25

In general, any Canadian withholding tax imposed on dividend payments in respect of the Warrant Shares will be treated as a foreign income tax eligible for credit against a U.S. Holder’s U.S. federal income tax liability (or, at a U.S. Holder’s election, may, in certain circumstances, be deducted in computing taxable income). Dividends paid on the Warrant Shares will be treated as foreign-source income, and generally will be treated as “passive category income” for U.S. foreign tax credit purposes. The Code applies various complex limitations on the amount of foreign taxes that may be claimed as a credit by U.S. taxpayers. Accordingly, U.S. Holders are urged to consult their own tax advisors regarding the availability of the foreign tax credit under their particular circumstances.

Sale, Exchange or Other Taxable Disposition of Warrant Shares

A U.S. Holder generally will recognize gain or loss upon the sale, exchange or other taxable disposition of Warrant Shares in an amount equal to the difference between (i) the amount realized upon the sale, exchange or other taxable disposition and (ii) such U.S. Holder’s adjusted tax basis in the Warrant Shares. Generally, subject to the application of the PFIC rules discussed below, such gain or loss will be capital gain or loss and will be long-term capital gain or loss if, on the date of the sale, exchange or other taxable disposition, the U.S. Holder has held the Warrant Shares for more than one year. For individual U.S. Holders, long-term capital gains are subject to taxation at favorable rates. The deductibility of capital losses is subject to limitations under the Code. Gain or loss, if any, realized upon a sale, exchange or other taxable disposition of the Warrant Shares will be treated as having a United States source for U.S. foreign tax credit limitation purposes. Consequently, a U.S. Holder may not be able to use any foreign tax credits arising from any Canadian tax imposed on the sale, exchange or other taxable disposition of the Warrant Shares unless such credit can be applied (subject to applicable limitations) against tax due on other income treated as derived from foreign sources or unless an applicable treaty provides otherwise.

Passive Foreign Investment Company Considerations

Special, generally unfavorable, U.S. federal income tax rules apply to U.S. persons owning stock of a PFIC. A foreign corporation will be considered a PFIC for any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable “look through” rules, either (1) at least 75 percent of its gross income is “passive” income (the “income test”) or (2) at least 50 percent of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income (the “asset test”). For purposes of determining whether a foreign corporation will be considered a PFIC, such foreign corporation will be treated as holding its proportionate share of the assets and receiving directly its proportionate share of the income of any other corporation in which it owns, directly or indirectly, more than 25 percent (by value) of the stock. PFIC status is fundamentally factual in nature. It generally cannot be determined until the close of the taxable year in question and is determined annually.

The Company has not made a formal determination as to whether it was a PFIC for the year ended June 30, 2021. The determination of PFIC status for any year is very fact specific, being based on the types of income the Company earns and the types and value of the Company’s assets from time to time, all of which are subject to change, as well as, in part, the application of complex U.S. federal income tax rules, which are subject to differing interpretations. As a result, there can be no assurance in this regard, and the IRS may challenge the Company’s classification. Accordingly, it is possible that the Company may be classified as a PFIC in a past year, in its current taxable year, or in future years. If the Company is classified as a PFIC in any year during which a U.S. Holder holds the Warrant Shares, the Company generally will continue to be treated as a PFIC as to such U.S. Holder in all succeeding years, regardless of whether the Company continues to meet the income or asset test discussed above. The Company intends to make a formal determination concerning its PFIC status for its June 30, 2021 tax year, and also promptly following the close of the current tax year, to communicate that determination to investors and endeavor to provide information required by investors for a QEF election (described below) if the Company determines that it is a PFIC.

S-26

If the Company were classified as a PFIC for any taxable year during which a U.S. Holder holds the Warrants or Warrant Shares, such U.S. Holder would be subject to increased tax liability (generally including an interest charge) upon the sale, exchange or other disposition of the Warrants or Warrant Shares or upon the receipt of certain distributions treated as “excess distributions”, regardless of whether such income was actually distributed. An excess distribution generally would be the portion of any distributions to a U.S. Holder with respect to the Warrants or Warrant Shares during a single taxable year that are in total greater than 125% of the average annual distributions received by such U.S. Holder with respect to the Warrants or Warrant Shares during the three preceding taxable years or, if shorter, during such U.S. Holder’s holding period for such Warrants or Warrant Shares. Generally, a U.S. Holder would be required to allocate any excess distribution or gain from the sale or other disposition of the Warrants or Warrant Shares rateably over its holding period for such Warrants or Warrant Shares. Such amounts would be taxed as ordinary income at the highest applicable rate in effect for each taxable year of the holding period, and amounts allocated to prior taxable years would be subject to an interest charge at a rate applicable to underpayments of tax. As described below under “Information Reporting and Backup Withholding”, if the Company were classified as a PFIC, such U.S. Holders would generally be required to file IRS Form 8261.

If the Company were classified as a PFIC, certain elections could be available to mitigate the consequences described above. If the Warrant Shares are regularly traded on a registered national securities exchange or certain other exchanges or markets, then such Warrant Shares will constitute “marketable stock” for purposes of the PFIC rules. The Company expects that the Warrant Shares will constitute “marketable stock” for purposes of the PFIC rules. U.S. Holders that make a “mark-to-market election” with respect to such marketable stock would not be subject to the foregoing PFIC rules. After making such an election, a U.S. Holder generally would include as ordinary income each year during which the election is in effect and during which the Company is a PFIC the excess, if any, of the fair market value of the Warrant Shares at the end of the taxable year over the U.S. Holder’s adjusted tax basis in such Warrant Shares. These amounts of ordinary income would not be eligible for the favourable tax rates applicable to qualified dividend income or long-term capital gains. A U.S. Holder with a mark-to-market election in effect also would be allowed to take an ordinary loss in respect of the excess, if any, of its adjusted tax basis in the Warrant Shares over their fair market value at the end of the taxable year (but only to the extent of the net amount of income that was previously included as a result of the mark-to-market election). A U.S. Holder’s tax basis in the Warrant Shares would be adjusted to reflect any income or loss amounts resulting from a mark-to-market election. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the Warrant Shares ceased to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consented to the revocation of the election. In the event that the Company is classified as a PFIC, U.S. Holders are urged to consult their own tax advisor regarding the availability of the mark-to-market election, and whether the election would be advisable in their particular circumstances.

The PFIC tax rules outlined above also would not apply, and different rules would apply, to a U.S. Holder that elected to treat the Company as a “qualified electing fund” or “QEF”. An election with respect to Warrant Shares to treat the Company as a QEF will not be available, however, if the Company does not provide the information necessary to make such an election. A QEF election may not be made with respect to the Warrants. U.S. Holders are urged to consult their own tax advisor regarding the manner and consequences of making a QEF election.

As discussed above in “Distributions”, notwithstanding any election made with respect to the Warrants or Warrant Shares, if the Company is a PFIC in either the taxable year of the distribution or the preceding taxable year, dividends received with respect to the Warrants or Warrant Shares will not qualify for reduced rates of taxation.

Receipt of Foreign Currency

The gross amount of any payment in a currency other than U.S. dollars will be included by each U.S. Holder in income in a U.S. dollar amount calculated by reference to the exchange rate in effect on the day such U.S. Holder

S-27

actually or constructively receives the payment in accordance with its regular method of accounting for U.S. federal income tax purposes regardless of whether the payment is in fact converted into U.S. dollars at that time. If the foreign currency is converted into U.S. dollars on the date of the payment, the U.S. Holder should not be required to recognize any foreign currency gain or loss with respect to the receipt of foreign currency. If, instead, the foreign currency is converted at a later date, any currency gains or losses resulting from the conversion of the foreign currency will be treated as U.S. source ordinary income or loss for U.S. foreign tax credit purposes. U.S. Holders are urged to consult their own U.S. tax advisors regarding the U.S. federal income tax consequences of receiving, owning, and disposing of foreign currency.

Additional Tax on Passive Income

U.S. Holders that are individuals, estates or trusts are required to pay an additional 3.8% tax on the lesser of (1) the U.S. Holder’s “net investment income” for the relevant taxable year and (2) the excess of the U.S. Holder’s modified adjusted gross income for the taxable year over a certain threshold. A U.S. Holder’s “net investment income” generally includes, among other things, dividends and net gains from disposition of property (other than property held in the ordinary course of the conduct of a trade or business). Accordingly, dividends on and capital gain from the sale, exchange or other taxable disposition of the Warrants or Warrant Shares may be subject to this additional tax. U.S. Holders are urged to consult their own tax advisors regarding the additional tax on passive income.

Information Reporting and Backup Withholding

In general, dividends paid to a U.S. Holder in respect of the Warrants or Warrant Shares and the proceeds received by a U.S. Holder from the sale, exchange or other disposition of the Warrants or Warrant Shares within the United States or through certain U.S.-related financial intermediaries will be subject to U.S. information reporting rules, unless a U.S. Holder is a Company or other exempt recipient and properly establishes such exemption. Backup withholding may apply to such payments if a U.S. Holder does not establish an exemption from backup withholding and fails to provide a correct taxpayer identification number and make any other required certifications.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against U.S. federal income tax liability, provided that the required information is timely furnished to the IRS.

In addition, U.S. Holders should be aware of reporting requirements with respect to the holding of certain foreign financial assets, including stock of foreign issuers which is not held in an account maintained by certain financial institutions, if the aggregate value of all of such assets exceeds U.S.$50,000. U.S. Holders must attach a complete IRS Form 8938, Statement of Specified Foreign Financial Assets, with their return for each year in which they hold our Warrants or Warrant Shares. U.S. Holders should also be aware that if the Company were a PFIC, they would generally be required to file IRS Form 8261, Information Return by a Shareholder of a Passive Foreign Investments Company or Qualified Electing Fund, during any taxable year in which such U.S. Holder recognizes gain or receives an excess distribution or with respect to which the U.S. Holder has made certain elections. U.S. Holders are urged to consult their own tax advisors regarding the application of the information reporting rules to the Warrants, the Warrant Shares and their particular situations.

ENFORCEABILITY OF CIVIL LIABILITIES BY U.S. INVESTORS

The Company is a corporation existing under the Business Corporations Act (British Columbia). Other than Martin Miguel, Margaret Shan Atkins and Lance Friedmann, all of our directors and officers, and all of the experts named in this Prospectus Supplement or the accompanying Base Prospectus, are residents of Canada or otherwise reside outside the United States, and all or a substantial portion of their assets, and a majority of the Company’s assets, are located outside the United States. The Company has appointed an agent for service of process in the United States, but it may be difficult for holders of Warrant Shares who reside in the United States to effect service within the United States upon those directors, officers and experts who are not residents of the United States. It may also be difficult for holders of the Securities who reside in the United States to realize upon judgments of courts of the United States predicated upon the Company’s civil liability and the civil liability of its directors, officers and experts under the United States federal securities laws.

The Company has been advised by its Canadian counsel, Stikeman Elliott LLP, that there is doubt as to the enforceability in Canada by a court in original actions, or in actions to enforce judgments of United States courts, of civil liabilities predicated upon United States federal securities laws.

The Company filed with the SEC, concurrently with our Registration Statement, an appointment of agent for service of process on Form F-X. Under the Form F-X, the Company appointed Puglisi & Associates as our agent for service of process in the United States in connection with any investigation or administrative proceeding

This offering is made by a Canadian issuer that is permitted, under a multijurisdictional disclosure system adopted by the United States and Canada, to prepare this Prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are different from those of the United States. Financial statements included or incorporated by reference herein have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and may not be comparable to financial statements of United States companies. Our financial statements are audited in accordance with the standards of the Public Company Accounting Oversight Board (United States).

The enforcement by investors of civil liabilities under the United States federal securities laws may be affected adversely by the fact that the Company is incorporated under the laws of British Columbia, Canada, that the majority of its officers and directors are residents of Canada, that all of the experts named in the registration statement are not residents of the United States, and that a substantial portion of the assets of the Company and said persons are located outside the United States.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION NOR HAS THE SEC PASSED UPON THE ACCURACY OR THE ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENCE.

You should carefully review the risks outlined in this Prospectus (together with any Prospectus Supplement) and in the documents incorporated by reference in this Prospectus and any Prospectus Supplement and consider such risks in connection with an investment in such Securities. See “Risk Factors”.

Prospective investors should be aware that the acquisition of the Securities described herein may have tax consequences both in the United States and in Canada. Such consequences for investors who are resident in, or citizens of, the United States may not be described fully herein. Prospective investors should read the tax discussion contained in the applicable Prospectus Supplement with respect to a particular offering of Securities.

The specific terms of the Securities with respect to a particular offering will be set out in one or more Prospectus Supplements and may include, where applicable: (i) in the case of Common Shares, the number of Common Shares offered, the offering price and any other specific terms; (ii) in the case of Warrants or Options, the number of Warrants or Options offered, the offering price, the designation, number and terms of the Common Shares issuable upon exercise of the Warrants or Options, any procedures that will result in the adjustment of these numbers, the exercise price, dates and periods of exercise, the currency in which the Warrants or Options are issued and any other specific terms; (iii) in the case of Subscription Receipts, the number of Subscription Receipts offered, the offering price, the procedures for the exchange of the Subscription Receipts for Common Shares or Warrants, as the case may be, and any other specific terms; (iv) in the case of Debt Securities, the specific designation, aggregate principal amount, the currency or the currency unit for which the Debt Securities may be purchased, the maturity, interest provisions, authorized denominations, offering price, covenants, events of default, any terms for redemption, any exchange or conversion terms, whether the debt is senior, senior subordinated or subordinated, whether the debt is secured or unsecured and any other terms specific to the Debt Securities being offered; and (v) in the case of Units, the designation, number and terms of the Common Shares, Warrants, Options, Subscription Receipts or Debt Securities comprising the Units. Where required by statute, regulation or policy, and where 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.

In addition, the Debt Securities that may be offered may be guaranteed by certain direct and indirect subsidiaries of Aurora with respect to the payment of the principal, premium, if any, and interest on the Debt Securities. The Company expects that any guarantee provided in respect of senior Debt Securities would constitute a senior and unsecured obligation of the applicable guarantor. For a more detailed description of the Debt Securities that may be offered, see “Description of Securities – Debt Securities - Guarantees”, below.

All information permitted under applicable securities legislation to be omitted from the Prospectus will be contained in one or more Prospectus Supplements that will be delivered to purchasers together with the Prospectus. Each Prospectus Supplement will be incorporated by reference into the Prospectus for the purposes of applicable 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. Investors should read the Prospectus and any applicable Prospectus Supplement carefully before investing in the Securities.

This Prospectus constitutes a public offering of the Securities only in those jurisdictions where they may be lawfully offered for sale and only by persons permitted to sell the Securities in such jurisdictions. We may offer and sell Securities to, or through, underwriters, dealers or selling securityholders, directly to one or more other purchasers, or through agents pursuant to exemptions from registration or qualification under applicable securities laws. A Prospectus Supplement relating to each issue of Securities will set forth the names of any underwriters, dealers, agents or selling securityholders involved in the offering and sale of the Securities and will

set forth the terms of the offering of the Securities, the method of distribution of the Securities, including, to the extent applicable, the proceeds to us and any fees, discounts, concessions or other compensation payable to the underwriters, dealers or agents, and any other material terms of the plan of distribution. This Prospectus may qualify an at-the-market distribution through a stock market or stock exchange outside of Canada. In connection with any offering of the Securities, other than an “at-the-market distribution” (as defined under National Instrument 44-102—Shelf Distributions (“NI 44-102”) of the Canadian Securities Administrators) unless otherwise specified in a Prospectus Supplement, the underwriters or agents may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a higher level than that which might exist in the open market. Such transaction, if commenced, may be interrupted or discontinued at any time. 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 an underwriter or dealer will over-allot securities in connection with such distribution or effect any other transactions that are intended to stabilise or maintain the market price of the Securities sold in the at-the-market distribution.

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

The Company’s outstanding Common Shares are listed for trading on the Toronto Stock Exchange (the “TSX”) and on the New York Stock Exchange (“NYSE”) under the trading symbol “ACB” and on the Frankfurt Stock Exchange (“FSE”) under the symbol “21P”. The closing price of the Company’s Common Shares on the TSX, NYSE and FSE on March 26, 2021 was $11.48 per Common Share, U.S.$9.11 per Common Share and €7.65 per Common Share, respectively. Unless otherwise disclosed in any applicable Prospectus Supplement, the Debt Securities, the Warrants, the Options, the Subscription Receipts and the Units will not be listed on any securities exchange. Unless the Securities are disclosed to be listed, there will be no market through which these Securities may be sold and purchasers may not be able to resell these 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.

We have filed an undertaking with the Alberta Securities Commission (the “ASC”) that we will not distribute in the local jurisdiction under this Prospectus specified derivatives or asset-backed securities that, at the time of distribution, are novel without pre-clearing with the ASC the disclosure to be contained in the Prospectus Supplement pertaining to the distribution of such securities.

Miguel Martin, the Chief Executive Officer and a director of the Company, and Margaret Shan Atkins and Lance Friedmann, directors of the Company, reside outside of Canada.

Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any such person, even though they have each appointed an agent for service of process.

The corporate head office of the Company is located at 4818 31 Street East, Edmonton International Airport, Alberta, Canada, T9E 0V6. The registered office of the Company is located at Suite 1500, 1055 West Georgia Street, Vancouver, British Columbia, V6E 4N7.

FORWARD LOOKING STATEMENTS

The Prospectus, including the documents incorporated by reference, contain forward-looking statements and forward-looking information (collectively, “forward-looking statements”) which may not be based on historical fact. These forward-looking statements are made as of the date of this Prospectus or the applicable document incorporated by reference herein. Forward-looking statements relate to future events or future performance and reflect Company management’s expectations or beliefs regarding future events. In certain cases, forward-looking statements can be identified by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved” or the negative of these terms or comparable terminology. In this document, certain forward-looking statements are identified by words including “may”, “future”, “expected”, “intends” and “estimates”. Although the Company believes that the expectations reflected in these forward-looking statements are reasonable, by their very nature forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. The Company provides no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. Forward-looking statements in this Prospectus and the documents incorporated by reference include, but are not limited to, statements with respect to:

The above and other aspects of the Company’s anticipated future operations are forward-looking in nature and, as a result, are subject to certain risks and uncertainties.

the Company’s continued growth and ongoing operations may require additional financing, which may not be available on acceptable terms or at all; any default under the Company’s existing debt that is not waived by the applicable lenders could materially adversely impact the Company’s results of operations and financial results and may have a material adverse effect on the trading price of the Company’s common shares; the Company may not be able to successfully develop new products or find a market for their sale; the Company may not have supply continuity given the Company’s asset rationalization initiative; as the cannabis market continues to mature, the Company’s products may become obsolete, less competitive, or less marketable;

the Company may have challenges in accessing banks and/or financial institutions in jurisdictions where cannabis is not yet federally regulated, which may adversely affect the Company’s growth plans; the business may be affected by political and economic instability; failure to comply with the Corruption of Foreign Public Officials Act (Canada) and the Foreign Corrupt Practices Act (United States), as well as the anti-bribery laws of the other nations in which the Company conducts business, could subject the Company to penalties and other adverse consequences;

Readers are cautioned that the foregoing list of risk factors is not exhaustive, and it is recommended that prospective investors consult the more complete discussion of risks and uncertainties facing the Company included in this Prospectus under the heading “Risk Factors”, as well as those set out in our 2020 AIF under the heading “Risk Factors” and in our 2020 Annual MD&A and Interim MD&A, each of which documents are incorporated by reference into this Prospectus. Readers are urged to consider the risks, uncertainties and assumptions carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on such information.

Should one or more of these risks or uncertainties materialize, or should underlying factors or assumptions prove incorrect, actual results may vary materially from those described in forward looking statements. Material factors or assumptions involved in developing forward-looking statements include, without limitation, publicly available information from governmental sources as well as from market research and industry analysis and on assumptions based on data and knowledge of the cannabis industry which the Company believes to be reasonable.

Although the Company believes that the expectations conveyed by the forward-looking statements are reasonable based on the information available to the Company on the date hereof, no assurance can be given as to future results, approvals or achievements. Forward-looking statements contained in this Prospectus and in the documents incorporated by reference herein are expressly qualified by this cautionary statement. The Company disclaims any duty to update any of the forward-looking statements after the date of this Prospectus except as otherwise required by applicable law.

NOTE TO UNITED STATES READERS REGARDING DIFFERENCES BETWEEN UNITED STATES AND CANADIAN FINANCIAL REPORTING PRACTICES

We prepare our financial statements in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (the “IASB”), which differs from U.S. generally accepted accounting principles (“U.S. GAAP”). Accordingly, our financial statements and other financial information included or incorporated by reference in this Prospectus may not be comparable to financial statements of United States companies prepared in accordance with U.S. GAAP.

NON-IFRS MEASURES

The information presented in this Prospectus, including certain documents incorporated by reference herein, may include non-IFRS measures that are used by us as indicators of financial performance. These financial measures do not have standardized meanings prescribed under IFRS and our computation may differ from similarly-named computations as reported by other entities and, accordingly, may not be comparable. These financial measures should not be considered as an alternative to, or more meaningful than, measures of financial performance as determined in accordance with IFRS as an indicator of performance. We believe these measures may be useful supplemental information to assist investors in assessing our operational performance and our ability to generate cash through operations. The non-IFRS measures also provide investors with insight into our decision making as we use these non-IFRS measures to make financial, strategic and operating decisions.

Because non-IFRS measures do not have a standardized meaning and may differ from similarly-named computations as reported by other entities, securities regulations require that non-IFRS measures be clearly defined and qualified, reconciled with their nearest IFRS measure and given no more prominence than the closest IFRS measure. If non-IFRS measures are included in documents incorporated by reference herein, information regarding these non-IFRS measures are presented in the sections dealing with these financial measures in such documents.

Non-IFRS measures are not audited. These non-IFRS measures have important limitations as analytical tools and investors are cautioned not to consider them in isolation or place undue reliance on ratios or percentages calculated using these non-IFRS measures.

The Company’s principal strategic business lines are focused on the production, distribution, and sale of cannabis and cannabis-derivative products in Canada and internationally. The Company’s primary market opportunities are:

Recent Developments

Global COVID-19 Pandemic

As at the date of this Prospectus, the production and sale of medical and consumer cannabis have been recognized as essential services across Canada and Europe. All of the Company’s facilities in Canada and internationally continue to be operational and we continue to work closely with local, national and international government authorities to ensure that we are following the required protocols and guidelines related to COVID-19 within each region. Although there have not been any significant impacts to the Company’s operations to date, the Company cannot provide assurance that there will not be disruptions to its operations in the future. Refer to the “Risk Factors” section in the 2020 Annual MD&A and the Interim MD&A for further discussion on the potential impacts of COVID-19.

10

January 2021 Public Offering

On January 26, 2021, the Company completed a bought deal public offering of units for total gross proceeds of U.S.$137.9 million. The Company issued a total of 13,200,000 units. Each unit consisted of one Common Share and one-half of one Common Share purchase warrant. Each whole warrant is exercisable for a period of 36 months and entitles the holder to purchase one Common Share at a price of U.S.$12.60 per common share.

Sale of Facilities

In January 2021, the Company entered into agreements to sell two of its production facilities for an aggregate of up to $24.6 million, subject to certain closing conditions. Upon closing, the Company will receive approximately 50% of the proceeds with the remaining 50% receivable upon, and subject to, the purchaser obtaining certain licenses.

Second Amended and Restated Credit Facility

On December 17, 2020, the Company entered into a second amended and restated credit facility (the “Second Amended Credit Facility”) with Bank of Montreal, as administrative agent, lead arranger and sole bookrunner (“BMO”) and certain lenders party thereto from time to time (collectively, the “Lenders”). The Second Amended Credit Facility replaced the Amended and Restated Credit Facility dated September 4, 2020, as amended. No changes were made to the commitment amounts under the facility, and the maturity date for the facility was extended to December 31, 2022. Seconded Amended Credit Facility provides for a minimum liquidity covenant rather than the minimum EBITDA covenants provided for under the prior facility.

Specifically, the milestone targets for each quarter ending December 31, 2020 through June 30, 2021, the adjusted EBITDA covenant for the trailing 12-month period ending June 30, 2021, and the maximum senior funded debt to Adjusted EBITDA ratio covenant have been eliminated. The Company agreed to: (A) increase the amount of unrestricted cash it will hold at all times to an amount equal to the lesser of (i) $75 million and (ii) two hundred and twenty-five percent of the outstanding principal amount under the term loan less the cash collateral posted by the Company, (B) introduce additional cash collateral of $50 million and (C) amend the amortization schedule to provide for principal payments of $6.25 million each fiscal quarter until maturity. There are no changes to the commitment amounts under the facility. The Second Amended Credit Facility has a first ranking general security interest in the assets of the Company and can be repaid without penalty at the Company’s discretion. In addition, the amended credit facility relieves the Company of the obligation to repay the credit facility with funds generated from future equity issuances.

The Second Amended Credit Facility contains customary representations and warranties, affirmative and negative covenants, and events of default. In addition, the Second Amended Credit Facility contains a negative covenant which restricts the Company from making or acquiring any Investments (as defined in the Second Amended Credit Facility) that, among other things, do not satisfy the definition of a Permitted Acquisition, as that term is defined in the Second Amended Credit Facility.

Effect of Reduction of Operations on Financial Results

In November 2020, the Company formally terminated construction activity and closed its Aurora Sun facility, and in December 2020 the Company reduced production at its Aurora Sky facility by 75%, consistent with previous public statements by the Company about aligning production to current demand. Aurora Sky is currently testing new processes and methodologies proven successful at other cultivation sites in Aurora’s network, with an increased focus on innovation led by deep plant science and genetics expertise. These decisions are designed to improve Aurora’s product quality, innovation and agility and improve working capital cycles to drive positive operating cash flow.

Cybersecurity Incident

In December 2020, the Company was the target of a cybersecurity incident that involved the theft of company information. The subsequent investigation identified that certain personally identifiable information of its employees and consumers was compromised. It also confirmed that the Company’s patient database was not compromised, and the Company’s performance and financial information was not impacted. All impacted individuals have been notified, as have all required government privacy offices. It is possible that further analysis will identify additional individuals affected or additional types of data accessed, which could result in additional notifications and negative publicity. Globally, cybersecurity incidents have increased in number and severity and it is expected that these external trends will continue. In response to this incident, or any potential future incident, the Company may incur substantial costs which may include:

THE SELLING SECURITYHOLDERS

Securities may be sold under this Prospectus by way of secondary offering by or for the account of certain of our securityholders. The Prospectus Supplement that we will file in connection with any offering of Securities by selling securityholders will include the following information:

USE OF PROCEEDS

Information regarding the use of the net proceeds from each offering of the Securities will be set forth in the Prospectus Supplement relating to the offering of the Securities. This information will include the net proceeds to the Company from the sale of the Securities, the use of those proceeds and the specific business objectives that the Company expects to accomplish with such proceeds.

All expenses relating to an offering of Securities and any compensation paid to underwriters, dealers or agents, as the case may be, will be paid out of our general funds, unless otherwise stated in the applicable Prospectus Supplement.

During the fiscal year ended June 30, 2020 and the second quarter ended December 31, 2020, the Company had negative cash flow from operating activities. Although the Company anticipates it will be able to generate positive cash flow from operating activities in the future, the Company cannot guarantee it will have positive cash flow from operating activities in any future period. To the extent that the Company has negative operating cash flow in any future period, current working capital and certain of the proceeds from the Offering may be used to fund such negative cash flow from operating activities. See “Risk Factors – Risks Related to Future Offerings – Negative Cash Flow from Operations”.

PLAN OF DISTRIBUTION

We may offer and sell Securities directly to one or more purchasers, through agents, or through underwriters or dealers designated by us from time to time. We may distribute the Securities from time to time in one or more transactions at fixed prices (which may be changed from time to time), at market prices prevailing at the times of sale, at varying prices determined at the time of sale, at prices related to prevailing market prices or at negotiated prices, including sales in transactions that are considered at-the-market distributions made through the facilities of a stock exchange or stock market outside of Canada, including the NYSE. A description of such pricing will be disclosed in the applicable Prospectus Supplement. No at-the-market offering as defined in NI 44-102 will be made under this Prospectus in Canada or through the facilities of a stock exchange or stock market in Canada. We may offer different classes of Securities in the same offering, or we may offer different classes of Securities in separate offerings.

This Prospectus may also, from time to time, relate to the offering of our Securities by certain selling securityholders. The selling securityholders may sell all or a portion of our Securities beneficially owned by them and offered thereby from time to time directly or through one or more underwriters, broker-dealers or agents. Our Securities may be sold by the selling securityholders in one or more transactions at fixed prices (which may be changed from time to time), at market prices prevailing at the time of the sale, at varying prices determined at the time of sale, at prices related to prevailing market prices or at negotiated prices.

A Prospectus Supplement will describe the terms of each specific offering of Securities, including: (i) the terms of the Securities to which the Prospectus Supplement relates, including the type of Security being offered; (ii) the name or names of any agents, underwriters or dealers involved in such offering of Securities; (iii) the name or names of any selling securityholders; (iv) the purchase price of the Securities offered thereby and the proceeds to, and the portion of expenses borne by, the Company from the sale of such Securities; (v) any agents’ commission, underwriting discounts and other items constituting compensation payable to agents, underwriters or dealers; and (vi) any discounts or concessions allowed or re-allowed or paid to agents, underwriters or dealers.

If Securities sold pursuant to a Prospectus Supplement are acquired by underwriters for their own account, they may be resold from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The obligations of the underwriters to purchase Securities will be subject to the conditions precedent agreed upon by the parties and the underwriters will be obligated to purchase all Securities under that offering if any are purchased. Any public offering price and any discounts or concessions allowed or re-allowed or paid to agents, underwriters or dealers may be changed from time to time.

Underwriters, dealers and agents who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Company to indemnification by the Company against certain liabilities, including liabilities under the U.S. Securities Act and Canadian 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.

In connection with any offering of Securities, other than an “at-the-market distribution”, the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time.

The Securities may also be sold: (i) directly by the Company or the selling securityholders at such prices and upon such terms as agreed to; or (ii) through agents designated by the Company or the selling securityholders from time to time. Any agent involved in the offering and sale of the Securities in respect of which this Prospectus is delivered will be named, and any commissions payable by the Company and/or selling

securityholder to such agent will be set forth, in the Prospectus Supplement. Unless otherwise indicated in the Prospectus Supplement, any agent is acting on a “best efforts” basis for the period of its appointment.

We and/or the selling securityholders may agree to pay the underwriters or agents a commission for various services relating to the issue and sale of any Securities offered under any Prospectus Supplement. In addition, underwriters or agents may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or agents and/or commissions from the purchasers for which they may act as agent. Agents, underwriters or dealers who participate in the distribution of the Securities may be entitled under agreements to be entered into with the Company and/or the selling securityholders to indemnification by the Company and/or the selling securityholders against certain liabilities, including liabilities under securities legislation, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof.

Each class or series of Warrants, Options, Subscription Receipts, Debt Securities and Units will be a new issue of Securities with no established trading market. Unless otherwise specified in the applicable Prospectus Supplement, Warrants, Options, Subscription Receipts, Debt Securities or Units will not be listed on any securities or stock exchange. Unless otherwise specified in the applicable Prospectus Supplement, there is no market through which the Warrants, Options, Subscription Receipts, Debt Securities or Units may be sold and purchasers may not be able to resell Warrants, Options, Subscription Receipts, Debt Securities or Units purchased under this Prospectus or any Prospectus Supplement. This may affect the pricing of the Warrants, Options, Subscription Receipts, Debt Securities or Units in the secondary market, the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer regulation. Subject to applicable laws, certain dealers may make a market in the Warrants, Options, Subscription Receipts, Debt Securities or Units, as applicable, but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given that any dealer will make a market in the Warrants, Options, Subscription Receipts or Units or as to the liquidity of the trading market, if any, for the Warrants, Options, Subscription Receipts, Debt Securities or Units.

In connection with any offering of Securities, unless otherwise specified in a Prospectus Supplement, underwriters or agents may over-allot or effect transactions which stabilize, maintain or otherwise affect the market price of Securities offered at levels other than those which might otherwise prevail on the open market. Such transactions may be commenced, interrupted or discontinued at any time.

The Securities may be issued alone or in combination and for such consideration determined by our board of directors.

Common Shares

The holders of Common Shares are entitled to receive notice of any meeting of the shareholders of the Company and to attend and vote thereat, except those meetings at which only the holders shares of another class or of a particular series are entitled to vote. Each Common Share entitles its holder to one vote. The holders of Common Shares are entitled to receive on a pro-rata basis such dividends as the board of directors may declare out of funds legally available therefor. In the event of the dissolution, liquidation, winding-up or other distribution of our assets, such holders are entitled to receive on a pro-rata basis all of assets of the Company remaining after payment of all of liabilities. The Common Shares carry no pre-emptive or conversion rights.

Warrants

This section describes the general terms that will apply to any Warrants for the purchase of Common Shares. To the extent required under applicable law, we will not offer Warrants for sale separately to any member of the public in Canada unless the offering of such Warrants is in connection with and forms a part of the consideration for an acquisition or merger transaction, or unless the applicable Prospectus Supplement containing the specific terms of the Warrants to be offered separately is first approved, in accordance with applicable laws, for filing by the securities commissions or similar regulatory authorities in each of the jurisdictions where the Warrants will be offered for sale.

Warrants may be issued directly by us to the purchasers thereof or under one or more warrant indentures or warrant agency agreements to be entered into by us and one or more banks or trust companies acting as warrant agent. Warrants, like other Securities that may be sold, may be listed on a securities exchange subject to exchange listing requirements and applicable legal requirements.
