⁽¹⁾Use of Non-GAAP Financial Information

In addition to the financial results presented in accordance with GAAP, SYNNEX also uses adjusted selling, general and administrative expenses, non-GAAP operating income, non-GAAP operating margin, non-GAAP income from continuing operations income, non-GAAP net income, and non-GAAP diluted earnings per share, which are non-GAAP financial measures that exclude transaction-related and integration expenses, the amortization of intangible assets, share-based compensation expense and the related tax effects thereon. The Company also uses adjusted earnings before interest, taxes, depreciation, and amortization (“Adjusted EBITDA”) which excludes other income (expense), net, transaction-related and integration expenses, and income from discontinued operations. In prior periods, SYNNEX has excluded other items relevant to those periods for purposes of its non-GAAP financial measures.

Transaction-related expenses typically consist of acquisition, integration, and divestiture related costs and are expensed as incurred. These expenses primarily represent costs for legal, banking, consulting and advisory services, and debt extinguishment fees. From time to time, this category may also include transaction-related gains/losses on divestitures/spin-off of businesses.

SYNNEX’ acquisition activities have resulted in the recognition of intangible assets which consist primarily of customer relationships and vendor lists. Definite-lived intangible assets are amortized over their estimated useful lives and are tested for impairment when events indicate that the carrying value may not be recoverable. The amortization of intangible assets is reflected in the Company’s statements of operations. Although intangible assets contribute to the Company’s revenue generation, the amortization of intangible assets does not directly relate to the sale of the Company’s products and the services performed for the Company’s clients. Additionally, intangible asset amortization expense typically fluctuates based on the size and timing of the Company’s acquisition activity. Accordingly, the Company believes excluding the amortization of intangible assets, along with the other non-GAAP adjustments which neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, enhances the Company’s and investors’ ability to compare the Company’s past financial performance with its current performance and to analyze underlying business performance and trends. Intangible asset amortization excluded from the related non-GAAP financial measure represents the entire amount recorded within the Company’s GAAP financial statements, and the revenue generated by the associated intangible assets has not been excluded from the related non-GAAP financial measure. Intangible asset amortization is excluded from the related non-GAAP financial measure because the amortization, unlike the related revenue, is not affected by operations of any particular period unless an intangible asset becomes impaired or the estimated useful life of an intangible asset is revised.

Share-based compensation expense is a non-cash expense arising from the grant of equity awards to employees based on the estimated fair value of those awards. Although share-based compensation is an important aspect of the compensation of our employees, the fair value of the share-based awards may bear little resemblance to the actual value realized upon the vesting or future exercise of the related share-based awards and the expense can vary significantly between periods as a result of the timing of grants of new stock-based awards, including grants in connection with acquisitions. Given the variety and timing of awards and the subjective assumptions that companies can use when calculating share-based compensation expense, SYNNEX believes this additional information allows investors to make additional comparisons between our operating results from period to period.

Additionally, SYNNEX refers to revenue at constant currency or adjusting for the translation effect of foreign currencies so that certain financial results can be viewed without the impact of fluctuations in foreign currency exchange rates, thereby facilitating period-to-period comparisons of SYNNEX’ business performance. Financial results adjusted for currency are calculated by translating current period activity in the transaction currency using the comparable prior year periods’ currency conversion rate. Generally, when the dollar either strengthens or weakens against other currencies, revenue at constant currency rates or adjusting for currency will be higher or lower than revenue reported at actual exchange rates.

Trailing fiscal four quarters ROIC is defined as the last four quarters’ tax effected operating income divided by the average of the last five quarterly balances of borrowings (excluding book overdraft) and equity, net of surplus cash. Adjusted ROIC is calculated by excluding the tax effected impact of non-GAAP adjustments from operating income and by excluding the cumulative tax effected impact of current and prior period non-GAAP adjustments on equity.

SYNNEX also uses free cash flow, which is cash flow from operating activities, reduced by purchases of property and equipment. SYNNEX uses free cash flow to conduct and evaluate its business because, although it is similar to cash flow from operations, SYNNEX believes it is an additional useful measure of cash flows since purchases of fixed assets are a necessary component of ongoing operations. Free cash flow reflects an additional way of viewing SYNNEX’ liquidity that, when viewed with its GAAP results, provides a more complete understanding of factors and trends affecting its cash flows. Free cash flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. For example, free cash flow does not incorporate payments for business acquisitions. Therefore, SYNNEX believes it is important to view free cash flow as a complement to its entire consolidated statements of cash flows.

SYNNEX management uses non-GAAP financial measures internally to understand, manage and evaluate the business, to establish operational goals, and in some cases for measuring performance for compensation purposes. These non-GAAP measures are intended to provide investors with an understanding of SYNNEX’ operational results and trends that more readily enable investors to analyze SYNNEX’ base financial and operating performance and to facilitate period-to-period comparisons and analysis of operational trends, as well as for planning and forecasting in future periods. Management believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision-making. As these non-GAAP financial measures are not calculated in accordance with GAAP, they may not necessarily be comparable to similarly titled measures employed by other companies. These non-GAAP financial measures should not be considered in isolation or as a substitute for the comparable GAAP measures and should be read only in conjunction with SYNNEX’ consolidated financial statements prepared in accordance with GAAP. A reconciliation of SYNNEX’ GAAP to non-GAAP financial information is set forth in the supplemental tables at the end of this press release.
