DESCARTES REPORTS FISCAL 2013 THIRD QUARTER FINANCIAL RESULTS

Record operating performance driven by 15% increase in year-over-year revenues

WATERLOO, Ontario — November 29, 2012 — The Descartes Systems Group Inc. announced its financial results for the fiscal 2013 third quarter (Q3FY13) ended October 31, 2012. 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).

Q3FY13 Financial Results

As described in more detail below, key financial highlights for Descartes in Q3FY13 included:

·   Revenues of $32.7 million, up 15% from $28.5 million in the third quarter of fiscal 2012 (Q3FY12) and up 7% from $30.5 million in the previous quarter (Q2FY13);

·   Services revenues of $29.7 million, up 13% from $26.2 million in Q3FY12 and up 1% from $29.3 million in Q2FY13;

·   Gross margin of 68%, up from 67% in Q3FY12 and 65% in Q2FY13;

·   Net income of $3.1 million, up 15% from $2.7 million in Q3FY12 and up 24% from $2.5 million in Q2FY13;

·   Earnings per share on a diluted basis of $0.05, up 25% from $0.04 in both Q3FY12 and Q2FY13;

·   Days-sales-outstanding (DSO) for Q3FY13 were 59 days, up from 53 days in Q3FY12 and 55 days in Q2FY13;

·   Adjusted EBITDA of $9.9 million, up 16% from $8.5 million in Q3FY12 and up 6% from $9.3 million in Q2FY13. Adjusted EBITDA as a percentage of revenues was 30%, consistent with 30% in both Q3FY12 and Q2FY13; and

·   Adjusted EBITDA per diluted share of $0.16, up 16% from $0.13 in Q3FY12 and up 7% from $0.15 in Q2FY13.

Adjusted EBITDA and Adjusted EBITDA per diluted share 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 and amortization (for which we include amortization of intangible assets, deferred compensation, stock-based compensation and related fees and taxes) and other charges (for which we include acquisition-related expenses and restructuring charges). These items are considered by management to be outside Descartes’ ongoing operational results. We define Adjusted EBITDA per diluted share as Adjusted EBITDA divided by the number of diluted shares used to calculate the GAAP measure of earnings per share. A reconciliation of Adjusted EBITDA and Adjusted EBITDA per diluted share to net income and earnings per share determined in accordance with GAAP, respectively, 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):

	Q3 FY13	Q2 FY13	Q1 FY13	Q4 FY12	Q3 FY12

Reconciliation of Non-GAAP Financial Measures - Adjusted EBITDA and Adjusted EBITDA per Diluted Share

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 per diluted share, 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 interest, taxes, depreciation and amortization (for which we include amortization of intangible assets, deferred compensation, stock-based compensation and related fees and taxes) and other charges (for which we include acquisition-related expenses and restructuring charges). Adjusted EBITDA per diluted share divides Adjusted EBITDA by the number of diluted shares used in calculating the GAAP diluted earnings per share, or diluted EPS, measure.

Management considers acquisition-related and restructuring activities 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 is a non-GAAP financial measure and may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA 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 does have limitations. In particular, we have completed ten acquisitions within the past four fiscal years, 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 non-recurring charges and expenses that are not part of operations.

The table below reconciles Adjusted EBITDA and Adjusted EBITDA per diluted share to net income and diluted earnings per share, respectively, reported in our unaudited Consolidated Statements of Operations for Q3FY13, Q2FY13, Q1FY13, Q4FY12 and Q3FY12, which we believe are the most directly comparable GAAP measures.
