DESCARTES REPORTS FISCAL 2017 SECOND QUARTER RESULTS

Record Revenues and Cash Provided by Operating Activities

WATERLOO, Ontario — September 8, 2016 — The Descartes Systems Group Inc. (TSX:DSG) (Nasdaq:DSGX) announced its financial results for its fiscal 2017 second quarter (Q2FY17) ended July 31, 2016. All financial results referenced are in United States (US) currency and, unless otherwise indicated, are determined in accordance with US Generally Accepted Accounting Principles (GAAP).

“This was another quarter of superior financial performance for Descartes, with record revenues and cash provided by our operations,” said Edward J. Ryan, Descartes’ CEO. “We believe that Descartes’ strong and growing margins demonstrate the leverage in our business model and Global Logistics Network to efficiently deliver quality services to our global client base. Descartes is a solid platform for continued growth and acquisitions, with the capital capacity and opportunities to continue or accelerate our pace of profitable growth.”

Q2FY17 Financial Results

As described in more detail below, key financial highlights for Descartes in Q2FY17 included:

Revenues of $50.5 million, up 12% from $45.2 million in the second quarter of fiscal 2016 (Q2FY16) and up 3% from $48.9 million in the previous quarter (Q1FY17);

Revenues were comprised of license revenues of $1.9 million and services revenues (non-license) of $48.6 million. Services revenues were up 14% from $42.8 million in Q2FY16 and up 2% from $47.5 million in Q1FY17. Services revenues comprised 96% of total revenues for the quarter;

Cash provided by operating activities of $16.6 million, up 30% from $12.8 million in Q2FY16 and up 4% from $15.9 million in Q1FY17;

Net income of $5.8 million, up 14% from $5.1 million in Q2FY16 and down from $6.0 million in Q1FY17. Net income as a percentage of revenues was 11%, compared to 11% in Q2FY16 and 12% in Q1FY17;

Earnings per share on a diluted basis of $0.08, up 14% from $0.07 in Q2FY16 consistent with Q1FY17; and

Adjusted EBITDA of $17.2 million, up 18% from $14.6 million in Q2FY16 and up 4% from $16.6 million in Q1FY17. Adjusted EBITDA as a percentage of revenues was 34%, up from 32% in Q2FY16 and consistent with Q1FY17.

Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues are non-GAAP financial measures provided as a complement to financial results presented in accordance with GAAP. We define Adjusted EBITDA as earnings before interest, taxes, depreciation, amortization, stock-based compensation (for which we include related fees and taxes) and other charges (for which we include restructuring charges and acquisition-related expenses). These items are considered by management to be outside Descartes' ongoing operational results. We define Adjusted EBITDA as a percentage of revenues as the quotient, expressed as a

percentage, from dividing Adjusted EBITDA for a period by revenues for the corresponding period. A reconciliation of Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues to net income determined in accordance with GAAP is provided later in this release.

The following table summarizes Descartes' results in the categories specified below over the past 5 fiscal quarters (unaudited; dollar amounts, other than per share amounts, in millions):

Safe Harbor Statement

This release contains forward-looking information within the meaning of applicable securities laws ("forward-looking statements") that relates to Descartes' growth in margins; continued growth and acquisitions; rate of profitable growth; demand for Descartes' solutions; growth of Descartes' Global Logistics Network; and other matters. These forward-looking statements 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; countries continuing to implement and enforce existing and additional trade restrictions and sanctioned party lists with respect to doing business with certain countries, organizations, entities and individuals; Descartes' 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 Descartes with access to capital; Descartes' continued ability to identify and source attractive and executable business combination opportunities; Descartes' ability to develop solutions that keep pace with the continuing changes in technology, and our continued compliance with third party intellectual property rights. These assumptions may prove to be inaccurate. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of Descartes, or developments in Descartes' business or industry, to differ materially from the anticipated results, performance or achievements or developments expressed or implied by such forward-looking statements. Such factors include, but are not limited to, Descartes' ability to successfully execute on acquisitions and to integrate acquired businesses and assets, and to predict expenses associated with and revenues from acquisitions; the ability to attract and retain key personnel and the ability to manage the departure of key personnel and the transition of our executive management team; changes in trade or transportation regulations that currently require customers to use services such as those offered by Descartes; the impact on Descartes' business of the global economic downturn; departures of key customers; the impact of foreign currency exchange rates; Descartes' ability to retain or obtain sufficient capital in addition to its debt facility to execute on its business strategy, including its acquisition strategy; disruptions in the movement of freight; the potential for future goodwill or intangible asset impairment as a result of other-than-temporary decreases in Descartes' market capitalization; and other factors and assumptions discussed in the section entitled, "Certain Factors That May Affect Future Results" in documents filed with the Securities and Exchange Commission, the Ontario Securities Commission and other securities commissions across Canada, including Descartes' most recently filed Management's Discussion and Analysis. If any such risks actually occur, they could materially adversely affect our business, financial condition or results of operations. In that case, the trading price of our common shares could decline, perhaps materially. Readers are cautioned not to place undue reliance upon any such forward-looking statements, which speak only as of the date made. Forward-looking statements are provided for the purpose of providing information about management's current expectations and plans relating to the future. Readers are cautioned that such information may not be appropriate for other purposes.

Reconciliation of Non-GAAP Financial Measures - Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues

We prepare and release quarterly unaudited and annual audited financial statements prepared in accordance with GAAP. We also disclose and discuss certain non-GAAP financial

information, used to evaluate our performance, in this and other earnings releases and investor conference calls as a complement to results provided in accordance with GAAP. We believe that current shareholders and potential investors in our company use non-GAAP financial measures, such as Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues, in making investment decisions about our company and measuring our operational results.

The term “Adjusted EBITDA” refers to a financial measure that we define as earnings before certain charges that management considers to be non-operating expenses and which consist of interest, taxes, depreciation, amortization, stock-based compensation (for which we include related fees and taxes) and other charges (for which we include restructuring charges and acquisition-related expenses). Adjusted EBITDA as a percentage of revenues divides Adjusted EBITDA for a period by the revenues for the corresponding period and expresses the quotient as a percentage.

Management considers these non-operating expenses to be outside the scope of Descartes’ ongoing operations and the related expenses are not used by management to measure operations. Accordingly, these expenses are excluded from Adjusted EBITDA, which we reference to both measure our operations and as a basis of comparison of our operations from period-to-period. Management believes that investors and financial analysts measure our business on the same basis, and we are providing the Adjusted EBITDA financial metric to assist in this evaluation and to provide a higher level of transparency into how we measure our own business. However, Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues are non-GAAP financial measures and may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues should not be construed as a substitute for net income determined in accordance with GAAP or other non-GAAP measures that may be used by other companies, such as EBITDA. The use of Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues does have limitations. In particular, we have completed nine acquisitions since the beginning of fiscal 2015, and may complete additional acquisitions in the future that will result in acquisition-related expenses and restructuring charges. As these acquisition-related expenses and restructuring charges may continue as we pursue our consolidation strategy, some investors may consider these charges and expenses as a recurring part of operations rather than expenses that are not part of operations.

The table below reconciles Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues to net income reported in our unaudited Consolidated Statements of Operations for Q2FY17, Q1FY17, Q4FY16, Q3FY16 and Q2FY16, which we believe is the most directly comparable GAAP measure.
