Such factors and risks as outlined above and in such filings do not constitute all factors and risks that could cause actual results of SGH to be materially different from our forward-looking statements.

Statement Regarding Use of Non-GAAP Financial Measures:

SGH management uses non-GAAP measures to supplement SGH's financial results under GAAP. Management uses these measures to analyze its operations and make decisions as to future operational plans, and believes that this supplemental non-GAAP information is useful to investors in analyzing and assessing the Company's past and future operating performance. These non-GAAP measures exclude certain items, such as share-based compensation expense, amortization of acquisition-related intangible assets, acquisition-related inventory adjustments, acquisition-related expenses, restructure charges and integration expenses, changes in the fair value of contingent consideration, (gains) losses from changes in currency exchange rates, COVID-19 expenses, amortization of convertible debt discount and other costs and other infrequent or unusual items. While amortization of acquisition-related intangible assets is excluded, the revenues from acquired companies is reflected in our non-GAAP measures and these intangible assets contribute to revenue generation. Management believes the presentation of operating results that exclude certain items provides useful supplemental information to investors and facilitates the analysis of the Company's core operating results and comparison of operating results across reporting periods. Management also uses adjusted EBITDA, which represents GAAP net income (loss), adjusted for net interest expense, income tax expense, depreciation and amortization expense, share-based compensation expense, acquisition-related inventory adjustments, acquisition-related expenses, restructure charges and integration expenses, changes in the fair value of contingent consideration, COVID-19 expenses and other infrequent or unusual items.

Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP, as they exclude important information about our financial results, as noted above. In addition, adjusted EBITDA does not purport to represent cash flow provided by, or used for, operating activities in accordance with GAAP and should not be used as a measure of liquidity. Investors are encouraged to review the "GAAP to Non-GAAP Reconciliations" in the appendix at the end of this presentation.
