Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company are prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) and pursuant to the regulations of the U.S Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The condensed consolidated financial statements include the Company’s accounts and those of its subsidiaries. In the opinion of the Company’s management, the financial information for the interim periods presented reflects all adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows. The results reported in these condensed consolidated financial statements are not necessarily indicative of results that may be expected for the entire year.

COVID-19 Pandemic

In March 2020, the World Health Organization declared the outbreak of a disease caused by a novel strain of the coronavirus (“COVID-19”) to be a pandemic. As of March 31, 2022, the impact of the COVID-19 pandemic continues to unfold and there has been uncertainty and disruption in the global economy and financial markets. The Company has considered the COVID-19 pandemic related impacts on its estimates, as appropriate, within its consolidated financial statements and there may be changes to those estimates in future periods.

The COVID-19 pandemic, as well as the response to mitigate the spread and effects of COVID-19, may impact the Company and its customers, as well as the demand for its products and services. The impact of COVID-19 on the Company’s operational results in subsequent periods will largely depend on future developments, and cannot be accurately predicted. These developments may include, but are not limited to, new information concerning the severity of COVID-19, the degree of success of actions take to contain or treat COVID-19 and the reactions by consumers, companies, governmental entities, and capital markets to such actions.

Recently Issued Accounting Standards

Recently Adopted Accounting Guidance

In October 2021, the FASB issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805) —Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, to require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. This standard is effective for calendar-year public business entities in 2023 and interim periods within that year, and early adoption is permitted. The Company has adopted this ASU as of January 1, 2021 and has retrospectively adjusted purchase accounting for the acquisition of EnvisionTEC, which is described in Note 4 to these condensed

consolidated financial statements, where deferred revenue was fair valued. As a practical expedient, the Company elected to estimate the standalone selling price for allocation purposes at the acquisition date. Upon the application of this practical expedient, the Company recognized deferred revenue as part of purchase accounting in the amount of $0.2 million and $12.5 million for the acquisitions of EnvisionTEC and ExOne, which is described in Note 4 to the financial statements, respectively.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740)—Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by eliminating some exceptions to the general approach in Accounting Standards Codification 740, Income Taxes. It also clarifies certain aspects of the existing guidance to promote more consistent application. This standard is effective for calendar-year public business entities in 2021 and interim periods within that year, and early adoption is permitted. The Company adopted the ASU as of January 1, 2021, which did not have a material effect on the Company’s condensed consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates the performance of Step 2 from the goodwill impairment test. In performing its annual or interim impairment testing, an entity will instead compare the fair value of the reporting unit with its carrying amount and recognize any impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss. The Company adopted the ASU as of January 1, 2021, which did not have a material effect on the Company’s condensed consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses. This ASU added a new impairment model (known as the current expected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses and entities will need to measure expected credit losses on assets that have a low risk of loss. The company adopted the ASU as of January 1, 2022, which did not have a material effect on the Company’s condensed consolidated financial statements.
