CALCULATION OF REGISTRATION FEE

The proposed maximum initial offering price per security will be determined, from time to time, by the Registrant. In no event will the aggregate initial offering price of all securities issued from time to time pursuant to this registration statement exceed U.S. $750,000,000.

(2)

Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(o) under the Securities Act of 1933, as amended.

(3)

Subject to footnote (1), there are being registered hereunder an indeterminate number of common shares, preferred shares, debt securities, subscription receipts, warrants and units in any combination as may be sold from time to time by the Registrant and/or certain selling securityholders.

           The Registrant hereby amends this registration statement on such date or dates as may be necessary to delay its effective date until the registration statement shall become effective as provided in Rule 467 under the Securities Act of 1933 or on such date as the Commission, acting pursuant to Section 8(a) of the Act, may determine.

        This Prospectus does not qualify for issuance debt securities in respect of which the payment of principal and/or interest may be determined, in whole or in part, by reference to one or more underlying interests including, for example, an equity or debt security, a statistical measure of economic or financial performance including, but not limited to, any currency, consumer price or mortgage index, or the price or value of one or more commodities, indices or other items, or any other item or formula, or any combination or basket of the foregoing items. For greater certainty, this Prospectus may qualify for issuance debt securities, including debt securities convertible into other Securities, in respect of which the payment of principal and/or interest may be determined, in whole or in part, by reference to published rates of a central banking authority or one or more financial institutions, such as a prime rate or bankers' acceptance rate, or to recognized market benchmark interest rates.

        The outstanding Common Shares are listed on the Toronto Stock Exchange (the "TSX") under the stock symbol "DSG" and listed on the NASDAQ Stock Market ("NASDAQ") under the symbol "DSGX". On May 23, 2018, the last reported sales price of our Common Shares on the TSX was C$39.09 per Common Share and on NASDAQ was US$30.45 per Common Share. Unless otherwise specified in the applicable Prospectus Supplement, the Preferred Shares, Debt Securities, Subscription Receipts, Warrants and Units will not be listed on any securities exchange. There is no market through which these Securities may be sold and purchasers may not be able to resell any Preferred Shares, Debt Securities, Subscription Receipts, Warrants or Units 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. See "Risk Factors" as well as the "Risk Factors" section of the applicable Prospectus Supplement.

        The Securities may be sold to or through underwriters or dealers purchasing as principals, by the Company or, in the case of Common Shares, by the Company and/or the Selling Securityholders or to one or more purchasers, directly pursuant to applicable statutory exemptions or through agents designated by the Company and/or the Selling Securityholders, as the case may be, 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. See "Plan of Distribution". Each Prospectus Supplement will identify the person offering Securities (the Company and/or, in the case of Common Shares, the Selling Securityholders) and each underwriter, dealer or agent engaged in connection with the offering and sale of those Securities to which the Prospectus Supplement relates, and will also set forth the method of distribution and the terms of the offering of such Securities including the net proceeds to the Company or, in the case of Common Shares, to the Company and/or the Selling Securityholders, as the case may be, and, to the extent applicable, any fees, discounts or other compensation payable to the underwriters, dealers or agents. Unless otherwise specified in a Prospectus Supplement, the offerings are subject to approval of certain legal matters by Blake, Cassels & Graydon LLP and Morgan, Lewis & Bockius LLP on behalf of the Company and/or the Selling Securityholders.

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

        Descartes' head office and registered office is located at 120 Randall Drive, Waterloo, Ontario, N2V 1C6.

        We are permitted, as a Canadian issuer, under the multi-jurisdictional disclosure system adopted by the United States ("U.S."), to prepare this Prospectus in accordance with Canadian disclosure requirements. You should be aware that such requirements are different from those of the U.S.

        The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP"). Accordingly, the presentation of consolidated financial statements may vary in a material way from consolidated financial statements prepared in accordance with International Financial Reporting Standards.

        You should be aware that the acquisition of the Securities described herein may have tax consequences both in the U.S. and in Canada. Such tax consequences for investors who are residents in, or citizens of, the U.S. may not be described fully herein or in any applicable Prospectus Supplement. You should read the tax discussion in any applicable Prospectus Supplement; however, this Prospectus or any applicable Prospectus Supplement may not fully describe these tax consequences, and you should consult your tax adviser prior to making any investment in the Securities.

        Your ability to enforce civil liabilities under U.S. federal securities laws may be affected adversely by the fact that the Company is incorporated under the laws of Canada, that some or all of our officers and directors may be residents of Canada, that some or all of the experts named in this Prospectus may be residents of Canada and that all or a substantial portion of our assets and the assets of such persons are located outside the U.S.

        Mr. David I. Beatson, Mr. Dennis Maple and Mr. John J. Walker, three of the Company's directors, as well as Edward J. Ryan, the Chief Executive Officer and a director of the Company, reside outside of Canada and each has appointed The Descartes Systems Group Inc., 120 Randall Drive, Waterloo, Ontario, N2V 1C6, as agent for service of process. Purchasers are advised that it may not be possible for investors to enforce judgments obtained in Canada against any person that resides outside of Canada, even if such person has appointed an agent for service of process. See "Service of Process and Enforceability of Civil Liabilities".

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

CAUTION REGARDING FORWARD-LOOKING INFORMATION AND STATEMENTS

        Certain statements made in this Prospectus, including the documents incorporated by reference herein, contain forward-looking information within the meaning of applicable securities laws ("forward-looking statements"). These forward-looking statements are presented for the purpose of assisting the Company's securityholders in understanding management's views regarding those future outcomes and may not be appropriate for other purposes. When used in this Prospectus, the words "may", "would", "could", "will", "intend", "plan", "anticipate", "believe", "seek", "propose", "estimate", "expect", and similar expressions, as they relate to the Company, are intended to identify forward-looking statements. Specific forward-looking statements in this Prospectus, including the documents incorporated by reference herein, include, but are not limited to: statements relating to business trends; the basis for any future growth and for our financial performance; the changing regulatory environment and its impact on our business; seasonality of our business; potential loss of recurring revenues; research and development and related expenditures; product and solution developments, enhancements and releases and the timing thereof; our building, development and consolidation of our network infrastructure; competition and changes in the competitive landscape; our management and protection of intellectual property and other proprietary rights; foreign sales and exchange rate fluctuations; cyclical or seasonal aspects of our business; our dividend policy; capital expenditures; potential legal proceedings; provisions of any Trust Indenture (as defined herein) or Debt Securities; and the creation and issuance of Preferred Shares.

        The forward-looking statements contained herein are based on certain assumptions including the following: global shipment volumes continuing to increase at levels consistent with the average growth rates of the global economy; countries continuing to implement and enforce existing and additional customs and security regulations relating to the provision of electronic information for imports and exports; our continued operation of a secure and reliable business network; the stability of general economic and market conditions, currency exchange rates, and interest rates; equity and debt markets continuing to provide us with access to capital; our continued ability to identify and source attractive and executable business combination opportunities; and our continued compliance with third party intellectual property rights. While management believes these assumptions to have been reasonable on the date of the forward-looking statements, they may prove to be inaccurate.

        Inherent in the forward-looking statements are known and unknown risks, uncertainties and other factors beyond the Company's ability to control or predict, that may cause the actual results, performance or achievements of the Company, or developments in the Company's business or in its industry, to differ materially from the anticipated results, performance, achievements or developments expressed or implied by such forward-looking statements. Some of the risks and other factors, some of which are beyond Descartes' control, which could cause results to differ materially from those expressed in the forward-looking statements and information contained in this Prospectus, including the documents incorporated by reference herein, include, but are not limited to: difficulties identifying, successfully integrating or maintaining or growing acquired businesses; failure to identify certain risks in connection with investments in acquisitions and other business initiatives; general global economic conditions which may affect our results of operations and financial condition; our existing customers might cancel contracts with us, fail to renew contracts on their renewal dates, and/or fail to purchase additional services and products and we may be unable to attract new customers; we may be unable to continue to innovate and to create new solutions and enhancements to our existing products; we may not remain competitive, and competition may increase; alternative sources for trade data may emerge or there may be increased adoption of such alternative sources; changes in the value of the U.S. dollar, as compared to the currencies of other countries where we transact business, could harm our operating results and financial conditions; system or network failures or information security breaches in connection with our services and products, and those of third parties on which we rely, could reduce our sales, impair our reputations, increase costs or result in liability claims, and seriously harm our

Table of Contents

business; failure to attract and retain key personnel would adversely affect our ability to develop and effectively manage our business; changes in government filing requirements for global trade may adversely impact our business; disruptions in the movement of freight could negatively affect our revenues; we have a substantial accumulated deficit and a history of losses and may incur losses in the future; our Common Share price has in the past been volatile and may also be volatile in the future; the fact that the market for Securities may be volatile and subject to wide fluctuations in response to numerous factors; we may need additional capital in the future and may be unable to obtain it or to obtain it on favorable terms; as we increase our international operations, we increase our exposure to international business risks; and there is currently no trading market for any Preferred Shares, Debt Securities, Subscription Receipts, Warrants or Units that may be offered pursuant to this Prospectus.

        This is not an exhaustive list of the factors that may affect any of the Company's forward-looking statements. Some of these and other factors are discussed in more detail in the section entitled "Certain Factors That May Affect Future Results" in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" contained in our 2018 Annual Report (as defined herein). Investors and others should carefully consider these and other factors and not place undue reliance on the forward-looking statements. Further information regarding these and other risk factors is included in the Company's public filings with provincial securities regulatory authorities which can be found on the System for Electronic Document Analysis and Retrieval ("SEDAR") website at www.sedar.com and with the United States Securities and Exchange Commission (the "SEC") which can be found on the Electronic Data-Gathering, Analysis and Retrieval ("EDGAR") website at www.sec.gov/edgar.shtml.

        The forward-looking statements contained in this Prospectus represent the Company's views only as of the date such statements were made. Forward-looking statements contained in this Prospectus are based on management's plans, estimates, projections, beliefs and opinions as at the time such statements were made and the assumptions related to these plans, estimates, projections, beliefs and opinions may change. Although Descartes believes that the expectations reflected in the forward-looking statements were reasonable at the time such statements were made, there can be no assurance that such expectations will prove to be correct. Descartes cannot guarantee future results, levels of activity, performance or achievements and actual results or developments may differ materially from those contemplated by the forward-looking statements. While the Company anticipates that subsequent events and developments may cause the Company's views to change, the Company does not undertake to update any forward-looking statements, except to the extent required by applicable securities laws.

        Consistent with past practice and in the normal course, the Company may have outstanding non-binding letters of intent and/or conditional agreements or may otherwise be engaged in discussions with respect to possible acquisitions and/or investments which may or may not be material.

The Company expects to continue to actively pursue acquisition and investment opportunities during the period that this Prospectus remains valid.

PURCHASERS' STATUTORY AND CONTRACTUAL RIGHTS

        Securities legislation in certain of the provinces of Canada provides purchasers with the right to withdraw from an agreement to purchase securities. This right may be exercised within two business days after receipt or deemed receipt of a prospectus and any amendment. In several of the provinces, the securities legislation further provides a purchaser with remedies for rescission or, in some jurisdictions, revision of the price or damages if the prospectus and any amendment contains a misrepresentation or is not delivered to the purchaser, provided that the remedies for rescission, revision of the price or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of these rights or consult with a legal adviser.

        In addition, original purchasers of convertible or exchangeable Preferred Shares, Subscription Receipts, Warrants (unless the Warrants are reasonably regarded by the Company as incidental to the applicable offering as a whole) or convertible or exchangeable Debt Securities (or Units comprised partly thereof) will have a contractual right of rescission against the Company in respect of the conversion, exchange or exercise of the convertible or exchangeable Preferred Share, Subscription Receipt, Warrant or the convertible or exchangeable Debt Security. The contractual right of rescission will be further described in any applicable Prospectus Supplement, but will, in general, entitle such

11

Table of Contents

original purchasers to receive the amount paid for the applicable convertible, exchangeable or exercisable security upon surrender of the underlying securities acquired thereby, in the event that this Prospectus (as supplemented or amended) contains a misrepresentation, provided that: (i) the conversion, exchange or exercise takes place within 180 days of the date of the purchase of the convertible, exchangeable or exercisable security under this Prospectus; and (ii) the right of rescission is exercised within 180 days of the date of the purchase of the convertible, exchangeable or exercisable security under this Prospectus.

        In an offering of convertible or exchangeable Preferred Shares, Subscription Receipts, Warrants or convertible or exchangeable Debt Securities (or Units comprised partly thereof), investors are cautioned that the statutory right of action for damages for a misrepresentation contained in the prospectus is limited, in certain provincial securities legislation, to the price at which convertible or exchangeable Preferred Shares, Subscription Receipts, Warrants or convertible or exchangeable Debt Securities (or Units comprised partly thereof) are offered to the public under the prospectus offering. This means that, under the securities legislation of certain provinces, if the purchaser pays additional amounts upon the conversion, exchange or exercise of the security, those amounts may not be recoverable under the statutory right of action for damages that applies in those provinces. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the particulars of this right of action for damages or consult with a legal adviser.

SERVICE OF PROCESS AND ENFORCEABILITY OF CIVIL LIABILITIES

        We are a Canadian company. Some of our directors and executive officers live outside the United States. Some of the assets of our directors and executive officers and some of our assets are located outside the United States. As a result, it may be difficult or impossible to serve process on us or on such persons in the United States or to obtain or enforce judgments obtained in U.S. courts or Canadian courts against them or us based on the civil liability provisions of the federal securities laws of the United States. There is doubt as to whether Canadian courts would enforce the civil liability claims brought under U.S. federal securities laws in original actions and/or enforce claims for punitive damages.

WHERE TO FIND MORE INFORMATION

        We have filed with the SEC a registration statement on Form F-10 relating to the Securities. This Prospectus, which constitutes a part of the registration statement, does not contain all of the information contained in the registration statement, certain items of which are contained in the exhibits to the registration statement as permitted by the rules and regulations of the SEC.

Indemnification

        Under the Canada Business Corporations Act (the "CBCA"), the Registrant may indemnify its current or former directors or officers or another individual who acts or acted at the Registrant's request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of his or her association with the Registrant or another entity, and the individual seeking indemnity shall have a right to such indemnity if such individual was not judged by the court or other competent authority to have committed any fault or omitted to do anything that such individual ought to have done.

        The CBCA also provides that the Registrant may advance monies to such an individual for the costs, charges and expenses of such a proceeding, provided that, such individual must repay the monies advanced if the individual does not fulfill the conditions in the following paragraph. The CBCA also provides that the Registrant may, with the approval of a court, indemnify such an individual or advance monies against all costs, charges and expenses reasonably incurred by the individual in connection with an action by or on behalf of the Registrant or other entity to procure a judgment in its favor, to which the individual is made a party because of the individual's association with the Registrant or other entity at the Registrant's request.

        However, indemnification under any of the foregoing circumstances is prohibited under the CBCA unless the individual:

•

acted honestly and in good faith with a view to the Registrant's best interests, or the best interests of the other entity for which the individual acted as director or officer or in a similar capacity at the Registrant's request; and



•

in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that his or her conduct was lawful.

        The Registrant's by-laws provide that the Registrant will indemnify a director or officer, a former director or officer or another individual who acts or acted at the Registrant's request as a director or officer (or an individual acting in a similar capacity) of another entity, and their heirs and legal representatives, against all costs, charges and expenses, including, without limitation, an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the Registrant or other entity.

        The Registrant's by-laws provide that the Registrant may advance monies to a director, officer or other individual for the costs, charges and expenses of a proceeding referred to above. That person must repay the monies if the person does not fulfill the conditions in the following paragraph.

        The Registrant's by-laws provide that the Registrant will not indemnify a person referred to above unless the person: (a) acted honestly and in good faith with a view to the best interests of the Registrant or, as the case may be, to the best interests of the other entity for which the person acted as a director or officer or in a similar capacity at the Registrant's request; and (b) in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the person had reasonable grounds for believing that the person's conduct was lawful.

        The Registrant's by-laws provide that the Registrant also has the right to indemnify a person referred to above in such other circumstances as the CBCA or law permits or requires. The Registrant's by-laws do not limit the right of any person entitled to indemnity to claim indemnity apart from the provisions of the Registrant's by-laws.

Table of Contents

        Subject to the CBCA, the Registrant may purchase and maintain insurance for the benefit of any individual referred to above as the board of directors of the Registrant may from time to time determine. The Registrant has purchased and maintains such an insurance policy. The Registrant has entered into standard indemnification agreements with its directors and executive officers.

        Under agreements which may be entered into by the Registrant, underwriters, dealers and agents who participate in the distribution of the Securities may be entitled to indemnification by Registrant against certain liabilities, including liabilities arising out of any misrepresentation in this Registration Statement and the documents incorporated by reference herein, other than liabilities arising out of any misrepresentation made by underwriters, dealers or agents who participate in the offering of the Securities.

        Insofar as indemnification for liabilities under the United States Securities Act of 1933, as amended, may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the U.S. Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is therefore unenforceable.
