One or more securityholders of the Company may also offer and sell Securities under this Prospectus (the "Selling Securityholders" and each a "Selling Securityholder"). See "Secondary Offering by Selling Securityholders". This Prospectus constitutes a public offering of Securities only in those jurisdictions where they may be lawfully offered for sale, and therein only by persons permitted to sell the Securities. The Company, or any Selling Securityholders, may offer and sell the Securities to or through underwriters purchasing as principal and may also sell the Securities to one or more purchasers directly, through applicable statutory exemptions, or through agents designated by the Company from time to time. The Securities may be sold from time to time in one or more transactions at fixed prices or not at fixed prices, such as market prices prevailing at the time of sale, prices related to such prevailing market prices or prices to be negotiated with purchasers, which prices may vary as between purchasers and during the period of distribution of the Securities. The Prospectus Supplement relating to a particular offering of Securities will identify each underwriter, dealer or agent engaged in connection with the offering and sale of such Securities, as well as the method of distribution and the terms of the offering of such Securities, including the initial offering price (in the event the offering is a fixed price distribution), the manner of determining the offering price(s) (in the event the offering is not a fixed price distribution), the net proceeds to the Company and, to the extent applicable, any fees, discounts or any other compensation payable to underwriters, dealers or agents and any other material terms. See "Plan of Distribution". This Prospectus may qualify as an "at-the-market distribution". The Securities may be offered and sold pursuant to this Prospectus through underwriters, dealers, directly or through agents designated from time to time at amounts and prices and other terms determined by us or any selling securityholders. In connection with any underwritten offering of Securities other than an "at-the-market distribution" (as defined in National Instrument 44-102 – Shelf Distributions ("NI 44-102")), unless otherwise specified in the relevant Prospectus Supplement, the underwriters may over-allot or effect transactions which stabilize or maintain the market price of the Securities offered at levels other than those that might otherwise prevail on the open market. Such transactions, if commenced, may be commenced, interrupted or (iii) 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 underwriter or dealer will over-allot Securities in connection with such distribution or effect any other transactions that are intended to stabilize or maintain the market price of the Securities. The Common Shares are listed and posted for trading on the Toronto Stock Exchange (the "TSX") under the symbol "HUT" and quoted on the OTCQX market under the symbol "HUTMF". On March 8, 2021, the last trading day prior to the date of this Prospectus, the closing price of the Common Shares on the TSX was $9.19 and on the OTCQX market was US$7.29. Unless otherwise specified in the applicable Prospectus Supplement, Debt Securities, Subscription Receipts, Warrants, Convertible Securities and Units will not be listed on any securities exchange. There is currently no market through which Securities other than Common Shares may be sold, and purchasers may not be able to resell such Securities purchased under this Prospectus. This may affect the pricing of the Securities in the secondary market, the transparency and availability of trading prices, the liquidity of the Securities, and the extent of issuer regulation.
