©2021 3D Systems, Inc. | All Rights Reserved.24 Presentation of Information 3D Systems reports is financial results in accordance with GAAP. To facilitate a better understanding of the impact that strategic acquisitions, non-recurring charges and certain non-cash expenses had on its financial results, management reviews certain non-GAAP measures, including non-GAAP revenue, non-GAAP Cost of Sales, non- GAAP Operating Income, non-GAAP Net Income (Loss), non-GAAP Basic and Diluted Income (Loss) per Share, non- GAAP Gross Profit, non-GAAP Gross Profit Margin, non-GAAP SG&A Expenses, non-GAAP R&D, non-GAAP Other Income and Expense and non-GAAP Operating Expenses, each of which exclude the impact of amortization of intangibles, acquisition and severance expenses, stock-based compensation expense, litigation settlements and charges related to strategic decisions and portfolio realignment, and Adjusted EBITDA, defined as non-GAAP Operating Income plus depreciation, and Adjusted EBITDA Margins to better evaluate period-over-period performance. A reconciliation of GAAP to non-GAAP results is provided in the accompanying schedule. 3D Systems does not provide forward-looking guidance on a GAAP basis. The company is unable to provide a quantitative reconciliation of these forward-looking non-GAAP measures to the most directly comparable forward- looking GAAP measures without unreasonable effort because 3D Systems cannot reliably forecast legal, acquisition and divestiture expenses, restructuring expenses, product end of life adjustments and goodwill impairment, which are difficult to predict and estimate. These items are inherently uncertain and depend on various factors, many of which are beyond the company’s control, and as such, any associated estimate and its impact on GAAP performance could vary materially.
