DESCARTES REPORTS FISCAL 2018 THIRD QUARTER FINANCIAL RESULTS

Global Logistics Network Drives Record Revenues

WATERLOO, Ontario — November 29, 2017 — The Descartes Systems Group Inc. (TSX:DSG) (Nasdaq:DSGX) announced its financial results for its fiscal 2018 third quarter (Q3FY18) ended October 31, 2017. 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).

“Our growth is driven by new customers and businesses joining the Global Logistics Network (GLN) and existing customers expanding their use of the GLN’s growing solution-set to manage the lifecycle of their shipments,” said Edward J. Ryan, Descartes’ CEO. “We continue to see opportunities to do even more with our customers to help isolate them from the complexities of the ever-changing global trade landscape, and demanding consumer and business buying environment. We believe we have a solid platform for continued growth and acquisitions, with the experience and capital capacity to continue to increase the GLN’s influence.”

Q3FY18 Financial Results

As described in more detail below, key financial highlights for Descartes’ three-month period ended October 31, 2017 (Q3FY18) included:

· Revenues of $62.0 million, up 20% from $51.5 million in the third quarter of fiscal 2017 (Q3FY17) and up 8% from $57.3 million in the previous quarter (Q2FY18);

· Revenues were comprised of license revenues of $2.3 million (4% of total revenues) and services revenues (non-license) of $59.7 million (96% of total revenues). Services revenues were up 21% from $49.4 million in Q3FY17 and up 8% from $55.1 million in Q2FY18;

· Cash provided by operating activities of $18.9 million, down from $20.5 million in Q3FY17 and up 11% from $17.1 million in Q2FY18;

· Net income of $6.2 million, up 5% from $5.9 million in Q3FY17 and down from $7.2 million in Q2FY18. Net income as a percentage of revenues was 10%, compared to 11% in Q3FY17 and 13% in Q2FY18;

· Earnings per share on a diluted basis of $0.08, consistent with $0.08 in Q3FY17 and down from $0.09 in Q2FY18; and

· Adjusted EBITDA of $20.6 million, up 16% from $17.8 million in Q3FY17 and up 4% from $19.8 million in Q2FY18. Adjusted EBITDA as a percentage of revenues was 33%, compared to 35% in Q3FY17 and 35% in Q2FY18.

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):

Cash Position

At October 31, 2017, Descartes had $33.3 million in cash. Cash decreased $54.2 million in Q3FY18 primarily due to cash used to acquire MacroPoint (described further below) and $4.8 million in 9MFY18 primarily due to cash used to acquire ShipRush, PCSTrac and MacroPoint  and, in both comparative periods, partially offset by proceeds from borrowing on the credit facility and cash provided by operating activities

The table set forth below provides a summary of cash flows for Q3FY18 and 9MFY18 in millions of dollars:

	Q3FY18			9MFY18
Cash provided by operating activities		18.9			52.5
Additions to property and equipment		(2.2	)		(3.9	)

Acquisition of MacroPoint

On August 14, 2017, Descartes acquired MacroPoint LLC (“MacroPoint”), an electronic transportation network providing location-based truck tracking and predictive freight capacity data content. US-based MacroPoint runs a connected network helping transportation brokers, logistics service providers and shippers track the locations of deliveries in trucks as well as predictive freight capacity to help identify early opportunities for additional freight moves. The purchase price for the acquisition was approximately $106.2 million, net of cash acquired, which was funded using $20.0 million of Descartes common shares, $80.0 million from drawing on Descartes’ existing credit facility and the balance using cash on hand.

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 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 a global economic downturn; changes in customer behaviour and expectations; Descartes’ ability to successfully design and develop enhancements to our products and solutions; 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.

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.

5

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 seven acquisitions since the beginning of fiscal 2017 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 Q3FY18, Q2FY18, Q1FY18, Q4FY17 and Q3FY17, which we believe is the most directly comparable GAAP measure.
