Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	(2) Basis of Presentation and Summary of Significant Accounting Policies (a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K filed with the SEC on March 18, 2022. The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited financial statements as of that date, but may not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, stockholders' equity (deficit) and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2022 or any future period. The Company has two reporting segments which are referred to as: (1) the United States (“U.S.”) and (2) International. Foreign Operations and Comprehensive Loss The U.S. dollar (“USD”) is the functional currency for Xometry’s consolidated subsidiary operating in the U.S. The primary functional currency for the Company's consolidated subsidiaries operating in Germany and to a lesser extent Japan is the Euro ("Euro") and the Yen, respectively. For the Company’s consolidated subsidiaries whose functional currencies are not the USD, the Company translates their financial statements into USD. The Company translates assets and liabilities at the exchange rate in effect as of the financial statement date. Revenue and expense accounts are translated using an average exchange rate for the period. Gains and losses resulting from translation are included in accumulated other comprehensive income (“AOCI”), as a separate component of equity. Noncontrolling Interest In connection with the acquisition of Thomas on December 9, 2021, we assumed a 66.67 % ownership in Incom Co., LTD. As we have a controlling interest in Incom Co., LTD, we have consolidated Incom Co., LTD into our financial statements. The portion of equity in Incom Co., LTD not owned by the Company is accounted for as a noncontrolling interest. We present the portion of any equity that we do not own in a consolidated entity as noncontrolling interest and classify their interest as a component of total equity, separate from total stockholders’ equity (deficit) on our Condensed Consolidated Balance Sheets. We include net income (loss) attributable to the noncontrolling interests in net income (loss) in our Condensed Consolidated Statements of Operations and Comprehensive Loss. (b) Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. In light of the currently unknown duration and severity of the COVID-19 pandemic, we face a greater degree of uncertainty than normal in making the judgments and estimates needed to apply our significant accounting policies. As of the date these condensed consolidated financial statements were issued, the impacts of the COVID-19 pandemic did not have a significant impact on our estimates or judgments. Judgments and assumptions may change, as new events occur and additional information is obtained, as well as other factors related to COVID-19 and economic recovery that could result in a meaningful impact on our consolidated financial statements in future reporting periods. (c) Business Combinations The Company accounts for business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to the valuation of intangible assets. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are reflected in the condensed consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred. (d) Fair Value Measurements and Financial Instruments The Company measures certain assets and liabilities at fair value on a recurring basis based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis, whereby inputs used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 - Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. The carrying amounts of certain of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, prepaid expenses and other assets, accounts payable, accrued expenses and contract liabilities approximate their fair values due to their short maturities. The Company's marketable securities are recorded at fair value. (e) Marketable Securities The Company measures its marketable securities at fair value and recognizes any changes in fair value in net loss. Our marketable securities represent our investment in a short term bond fund and a money market fund. We consider our marketable securities as available for use in current operations, and therefore classify these securities as current assets on the Condensed Consolidated Balance Sheets. As of March 31, 2022 and December 31, 2021, the Company's marketable securities of $ 309.7 million and $ 30.5 million, respectively were recorded at fair value, within Level 1 of the fair value hierarchy. The fair value of the Company’s Level 1 financial instruments is based on quoted prices in active markets, total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs, discounts or blockage factors. During the three months ended March 31, 2022, the Company recorded an unrealized loss of $ 0.9 million related to these securities which is recorded in other expenses on the Condensed Consolidated Statements of Operations and Comprehensive Loss. No unrealized gains (losses) were recorded during the three months ended March 31, 2021. (f) Accounts Receivable Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. For buyers for which Xometry provides credit, the Company performs credit inquiries, including references checks, and queries credit ratings services and other publicly available information. Amounts collected on accounts receivable are included in net cash provided by operating activities in the statements of cash flows. Management provides for probable uncollectible amounts through a provision for bad debt expense and an adjustment to a valuation allowance based on its experience and judgment. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. (g) Property and Equipment and Long-Lived Assets Property and equipment are stated at cost. Equipment under finance leases is stated at the present value of minimum lease payments. Depreciation is calculated on the straight-line method over the estimated useful life of the assets, which range from three to seven years , or in the case of leasehold improvements, over the shorter of the remaining lease term or the useful life of the asset. Property and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Property and equipment includes capitalized internal-use software development costs. Eligible internal-use software development costs are capitalized subsequent to the completion of the preliminary project stage. Such costs include internal and external direct development costs totaling $ 2.2 million for the three months ended March 31, 2022 and $ 5.2 million for the year ended December 31, 2021. After all substantial testing and deployment is completed and the software is ready for its intended use, capitalization is discontinued and the internal-use software costs are placed in service and amortized using the straight-line method over the estimated useful life of the software, generally three years. (h) Revenue The Company derives the majority of its marketplace revenue in the U.S. and Europe from the sale of parts and assemblies fulfilled using a vast network of suppliers. The Company recognizes revenue from the sales to our customers pursuant to Financial Accounting Standard Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company determines that a contract exists between the Company and the customer when the customer accepts the quote and places the order, all of which are governed by the Company’s standard terms and conditions or other agreed terms with Xometry’s buyers. Upon completion of an order through Xometry’s platform, the Company identifies the performance obligation(s) within that order to complete the sale of the manufactured part(s) or assembly. Using Xometry’s in-house technology, the Company determines the price for the manufactured part(s) or assembly on a stand-alone basis at order initiation. The Company recognizes revenue from sales to Xometry’s customers upon shipment, at which point control over the part(s) or assembly have transferred. The Company has concluded that the Company is principal in the sale of part(s) and assemblies that use the Company’s network of third-party manufacturers because the Company controls the manufacturing by obtaining a right to direct a third-party manufacturer to fulfill the performance obligation Xometry has with the Company’s customers on Xometry’s behalf. The Company has considered the following conditions of the sale: (i) the Company has the obligation of providing the specified product to the customer, (ii) the Company has discretion with respect to establishing the price of the product and the price the Company pays the suppliers and the Company has margin risk on all of Xometry’s sales, (iii) the Company has discretion in determining how to fulfill each order, including selecting the supplier and (iv) Xometry bears certain risk for product quality to the extent the customer is not satisfied with the final product. Xometry also derives revenue from its supplier services which is a suite of services offered to our suppliers. In connection with the acquisition of Thomas on December 9, 2021, our revenue also includes the sale of advertising. This revenue is generally recognized as control is transferred to the customer, in an amount reflecting the consideration we expect to be entitled to in exchange for such product or service. A purchase order with a customer may involve multiple performance obligations, including a combination of some or all of our products. Judgment may be required in determining whether products are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation. Revenue is recognized over the period or at the point in time in which the performance obligations are satisfied. Consideration is typically determined based on a fixed unit price for the quantity of product transferred. For purchase orders involving multiple performance obligations, the transaction price is allocated to each performance obligation based on relative standalone selling price, and recognized as revenue when each individual product or service is transferred to the customer. Revenue is shown net of estimated returns, refunds, and allowances. As of March 31, 2022 and December 31, 2021, the Company has a $ 0.3 million and $ 0.2 million, respectively, provision for estimated returns, refunds or allowances. Sales tax collected from customers and remitted to governmental authorities is excluded from revenue. Contract Liabilities Contract liabilities are primarily derived from payments received in advance or at the time an order is placed, for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria described above. The following table is a summary of the contract liabilities as of December 31, 2021 and March 31, 2022 (in thousands): Contract liabilities at December 31, 2021 $ 7,863 Revenue recognized ( 36,958 ) Payments received in advance 39,103 Contract liabilities at March 31, 2022 $ 10,008 During the period ended March 31, 2022, the Company recognized approximately $ 7.2 million of revenue related to its contract liabilities at December 31, 2021. Sales Contract Acquisition Costs The Company’s incremental costs to obtain a contract may include a sales commission which is generally determined on a per order basis. For contracts in excess of one year, the Company amortizes such costs on a straight-line basis over the average customers life of two years for new customers and over the renewal period for existing customers which is generally one year . Sales commissions are included in Xometry’s sales and marketing expenses and cost of revenue in the Condensed Consolidated Statements of Operations and Comprehensive Loss. For the three months ended March 31, 2022, we recognized approximately $ 2.2 million of amortization related to deferred sales commissions. (i) Cost of Revenue Cost of revenue for marketplace primarily consists of the cost of the products that are manufactured or produced by the Company’s suppliers for delivery to buyers on the Company's platform, internal and external production costs, shipping costs, and certain internal depreciation. Cost of revenue for supplier services primarily consists of internal and external production costs and website hosting. (j) Leases The Company determines if an arrangement contains a lease and the classification of that lease, if applicable, at its inception. Operating leases are included in operating lease right-of-use ("ROU") assets, operating lease liabilities and operating lease liabilities (net of current portion) in the Condensed Consolidated Balance Sheets. The Company has finance leases as detailed in the Long-Lived Assets section above. For leases with terms of twelve months or less, the Company does not recognize a ROU assets or lease liabilities on the Condensed Consolidated Balance Sheets. Additionally, the Company elected to use the practical expedient to not separate lease and non-lease components for leases of real estate, meaning that for these leases, the non-lease components are included in the associated ROU asset and lease liability balances on the Company’s Condensed Consolidated Balance Sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments under the lease. Operating lease ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within the Company’s operating leases is generally not determinable, as such the Company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of the Company’s leases include options to extend or terminate the lease. The expected lease term includes options to extend or terminate the lease when it is reasonably certain the Company will exercise such option. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. (k) Sales and Marketing Sales and marketing expenses are expensed as incurred and include the costs of digital marketing strategies, branding costs and other advertising costs, certain depreciation and amortization expense, and compensation expenses, including stock-based compensation, to the Company’s sales and marketing employees. For the three months ended March 31, 2022 and 2021, the Company’s advertising costs were $ 7.1 million and $ 4.2 million, respectively. (l) Operations and Support Operations and support expenses are the costs the Company incurs in support of buyers and suppliers on Xometry’s platforms which are provided by phone, email and chat for purposes of resolving buyer and supplier related matters. These costs primarily consist of compensation expenses of the support staff, including stock-based compensation, certain depreciation and amortization expense and software costs used in delivering buyer and supplier services. (m) Product Development Product development costs which are not eligible for capitalization are expensed as incurred. This account also includes compensation expenses, including stock-based compensation to the Company’s employees performing these functions and certain depreciation and amortization expense. (n) General and Administrative General and administrative expenses primarily consist of professional service fees and certain depreciation and amortization expense. It also includes compensation expenses, including stock-based compensation expenses, for executive, finance, legal and other administrative personnel. (o) Stock Based Compensation All stock based compensation, including stock options and restricted stock units are measured at the grant date fair value of the award. The Company estimates grant date fair value of stock options using the Black-Scholes option-pricing model. The fair value of stock options and restricted stock units is recognized as compensation expense on a straight-line basis over the requisite service period, which is typically four years . The fair value of the restricted stock units is determined using the fair value of the Company's Class A common stock on the date of grant. Forfeitures are recorded in the period in which they occur. The Black-Scholes model considers several variables and assumptions in estimating the fair value of stock-based awards. These variables include: • expected annual dividend yield; • expected volatility over the expected term; • expected term; • risk free interest rate; • per share value of the underlying common stock; and • exercise price. For all stock options granted, the Company calculated the expected term using the simplified method for “plain vanilla” stock option awards. The risk-free interest rate is based on the yield available on U.S. Treasury issuances similar in duration to the expected term of the stock-based award. As there was no public market for the Company's common stock prior to the initial public offering (“IPO”), the Company estimates its expected share price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. The Company utilized a dividend yield of zero, as it had no history or plan of declaring dividends on its common stock. (p) Net Loss Per Share Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period. For periods in which the Company reports net losses, diluted net loss per common share is the same as basic net loss per common share, because all potentially dilutive securities are anti-dilutive. Vested RSUs that have not been settled have been included in the appropriate common share class used to calculate basic net loss per share. Subsequent to the Company's IPO on July 2, 2021, the Company computes net loss per share using the two-class method required for multiple classes of common stock and participating securities. The two-class method requires income available to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. Certain unvested share-based payment awards that contain nonforfeitable rights to dividends are treated as participating securities and therefore included in computing net income per share using the two-class method. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are substantially identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock shared proportionately in the Company’s net losses. (q) Recently Issued Accounting Standards New Accounting Pronouncements Effective in the Period Ended March 31, 2022 In August 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”) , which reduced the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that would have previously been accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. We adopted ASU 2020-06 on January 1, 2022 . As a result of the adoption of ASU 2020-06, the convertible notes issued in February 2022 were considered to be debt with no allocation to equity. New Accounting Pronouncements Effective in Future Periods In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (“Topic 326”), Measurement of Credit Losses on Financial Instruments . Topic 326 changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assets and net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowance for credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Topic 326 is effective as of January 1, 2023. Early adoption is permitted. The Company is currently evaluating the impact of Topic 326 on its consolidated financial statements and related disclosures. There are currently no other accounting standards that have been issued, but not yet adopted, that are expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows upon adoption.

Acquisitions	(7) Acquisitions Big Blue Saw On November 1, 2021, the Company acquired Big Blue Saw subject to an Asset Purchase Agreement. The acquisition of Big Blue Saw extends our marketplace capabilities in water jet and laser cutting. The Company accounted for the acquisition as a business combination. The aggregate non-contingent portion of the purchase price was $ 1.5 million and was paid in cash and Class A common stock on the acquisition date. In addition, the purchase price included a contingent consideration arrangement to the former owner of Big Blue Saw up to a maximum amount of $ 1.0 million (undiscounted) in two installments on the first and second anniversary of the acquisition and is based on client conversions. The initial fair value of the contingent consideration of $ 0.9 million was estimated by applying an income valuation approach. The measurement is based on inputs that are not observable in the market (Level 3 inputs). Key assumptions made include (a) discount rate and (b) probability weighted assumptions about client conversions. During the three months ended March 31, 2022, the Company recorded an approximate $ 31 thousand increase to the contingent consideration liability with a corresponding expense recognized in general and administrative expense on our Condensed Consolidated Statement of Operations and Comprehensive Loss. The Company re-evaluated the fair value of the contingent consideration based on current information available to the Company subsequent to our acquisition using a similar methodology as described above. As of March 31, 2022 and December 31, 2021, the total contingent consideration had a fair value of $ 0.9 million and $ 0.9 million, respectively. The Company performed a preliminary valuation analysis of the fair market value of the acquired assets and liabilities of Big Blue Saw during the fourth quarter of 2021. The final purchase price allocation will be determined when the Company has completed and fully reviewed all information necessary to finalize the fair value of the acquired assets and liabilities. The final allocation could differ materially from the preliminary allocation and may include changes in allocations to current asset, current liabilities and goodwill. No changes to the initial purchase price allocation were made during the three months ended March 31, 2022. FactoryFour On November 5, 2021, the Company acquired FactoryFour subject to an Asset Purchase Agreement. FactoryFour provides a SaaS based solution to help manufacturers improve lead times and make strong, data-driven decisions through real-time production tracking. The Company accounted for the acquisition as a business combination. The aggregate non-contingent portion of the purchase price was $ 3.3 million and was paid in cash and Class A common stock on the acquisition date. In addition, the purchase price includes a contingent consideration arrangement to the former owners of FactoryFour up to a maximum amount of $ 2.5 million (undiscounted) in three installments on the first, second and third anniversary of the acquisition and is based on gross total orders. The fair value of the initial contingent consideration of $ 1.5 million was estimated by applying an option pricing model. The measurement is based on inputs that are not observable in the market (Level 3 inputs). Key assumptions made include (a) discount rate, (b) time to expiration, (c) stock price, (d) hurdle rate, (e) risk free rate, (f) volatility, (g) dividend rate and (f) assumptions about gross total orders. During the three months ended March 31, 2022, the Company recorded an approximate $ 0.4 million increase to the contingent consideration liability with a corresponding expense recognized in general and administrative expense on our Condensed Consolidated Statement of Operations and Comprehensive Loss. The Company re-evaluated the fair value of the contingent consideration based on current information available to the Company subsequent to our acquisition. To estimate the current fair value we applied an income valuation approach. The measurement is based on inputs that are not observable in the market (Level 3 inputs). Key assumptions made include (a) discount rate and (b) probability weighted assumptions about gross total orders. As of March 31, 2022 and December 31, 2021, the total contingent consideration had a fair value of $ 1.9 million and $ 1.5 million, respectively. The Company performed its initial valuation analysis of the fair market value of the acquired assets and liabilities of FactoryFour during the fourth quarter of 2021. The Company finalized its valuation analysis in the first quarter of 2022. No changes to the initial purchase price allocation were made during the three months ended March 31, 2022. Thomas On December 9, 2021, the Company acquired Thomas subject to the merger agreement. Xometry leverages Thomas’ marketing and data services to deliver a suite of end-to-end services for suppliers with additional financial services and digital marketing products. The Company accounted for the acquisition as a business combination. The goodwill of $ 247.3 million arising from the acquisition of Thomas related to certain expected synergies which includes the ability to drive buyers and suppliers on to our platform and provide additional products and services. This goodwill which is included in our U.S. reporting segment is not expected to be deductible for tax purposes. The aggregate non-contingent portion of the purchase price was approximately $ 276.3 million and was paid in cash and Class A common stock on the acquisition date. The Company performed a preliminary valuation analysis of the fair market value of the acquired assets and liabilities of Thomas during the fourth quarter of 2021. The final purchase price allocation will be determined when the Company has completed and fully reviewed all information necessary to finalize the fair value of the acquired assets and liabilities. The final allocation could differ materially from the preliminary allocation and may include changes in allocations to current and long term asset, current and long term liabilities, deferred tax liabilities and goodwill. During the three months ended March 31, 2022, the Company recorded additional goodwill of approximately $ 0.6 million in connection with the identification of a deferred tax liability. This deferred tax liability was subsequently recognized into income during the three months ended March 31, 2022. The following table (in thousands) summarizes the consideration paid for Thomas and the preliminary fair value of the assets acquired and liabilities assumed on the acquisition date: Consideration: Cash $ 174,838 Fair value of Class A common stock 101,499 Fair value of consideration 276,337 Acquisition costs included in general and administrative for the three months ended March 31, 2022 — Recognized amounts of identifiable assets acquired and liabilities assumed: Current assets 18,244 Property and equipment 890 Intangible assets 40,400 Right-of-use assets 24,130 Other long term assets 250 Investment in unconsolidated joint venture 4,156 Lease liabilities ( 18,690 ) Deferred tax liability ( 559 ) Income taxes payable ( 1,647 ) Other long term liabilities ( 281 ) Contract liabilities ( 6,634 ) Current liabilities ( 30,183 ) Noncontrolling interest ( 1,036 ) Total identifiable net assets assumed 29,040 Goodwill 247,297 Total $ 276,337 The following table (in thousands) summarizes the fair value of the identifiable intangible assets: Total Estimated life Customer relationships $ 36,600 15 Database 2,400 5 Trade name 800 10 Developed technology 600 5 Total intangible assets $ 40,400 The estimated fair value of the intangible assets acquired was determined by the Company. The Company engaged a third‑party expert to assist with the valuation analysis. The Company used a relief from royalty method to estimate the fair values of the developed technology, database and tradename and a multi-period excess earnings method to estimate the fair value of the customer relationships. To measure the fair value of the noncontrolling interest, the Company used a market approach which considered historical revenues of the investee and market multiples (Level 3 inputs). Thomas’ results of operations were included in the Company's consolidated financial statements from the date of acquisition, December 9, 2021. The following unaudited pro forma condensed combined financial information gives effect to the acquisition of Thomas as if it was consummated on January 1, 2021 (the beginning of the comparable prior reporting period), and includes pro forma adjustments related to the amortization of acquired intangible assets. This unaudited data is presented for informational purposes only and is not intended to represent or be indicative of the results of operations that would have been reported had the acquisition occurred on January 1, 2021.

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	(10) Stock Based Compensation In 2014, the Company adopted a stock compensation plan (the "2014 Equity Incentive Plan") pursuant to which the Company may grant stock options, stock purchase rights, restricted stock awards, or stock awards to employees, directors and consultants (including prospective employees, directors, and consultants). This plan was terminated in February 2016 . No additional awards may be granted under the 2014 Equity Incentive Plan, however, outstanding awards continue in full effect in accordance with their existing terms. In 2016, the Company adopted a stock compensation plan (the “2016 Equity Incentive Plan”) pursuant to which the Company may grant stock options, stock purchase rights, restricted stock awards, or stock awards to employees, directors and consultants (including prospective employees, directors, and consultants). No additional awards may be granted under the 2016 Equity Incentive Plan, however, outstanding awards continue in full effect in accordance with their existing terms. In connection with the IPO on July 2, 2021, the Company's board of directors adopted the 2021 Equity Incentive Plan (the "2021 Equity Incentive Plan"). The 2021 Equity Incentive Plan provides for the grant of incentive stock options ("ISOs"), nonstatutory stock options ("NSOs"), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based awards and other awards, or collectively, awards. ISOs may be granted only to Xometry employees, including Xometry officers, and the employees of Xometry affiliates. All other awards may be granted to Xometry employees, including our officers, Xometry non-employee directors and consultants and the employees and consultants of Xometry affiliates. As of March 31, 2022, there were 5,219,760 shares available for the Company to grant under the 2021 Equity Incentive Plan. Stock Options Prior to the Company's IPO on July 2, 2021, the fair value of the Company’s common stock was estimated by management as there was no public market for the Company’s common stock. Xometry’s market-based methodology considered a number of objective and subjective factors including third-party valuations of its common stock, the valuation of comparable companies, sales of the Company’s convertible preferred stock to outside investors in arms-length transactions, the Company’s operating and financial performance, the lack of marketability, and general and industry specific economic outlook, amongst others.

Income Taxes	(11) Income Taxes A full valuation allowance has been established against our net U.S. federal and state deferred tax assets and foreign deferred tax assets, including net operating loss carryforwards. During the three months ended March 31, 2022, the Company has a $ 0.6 million income tax benefit in the U.S. The Company had no current or deferred income tax benefit or expense in the U.S. or outside the U.S. for the three months ended March 30, 2021. This effective tax rate of 0 % differs from the U.S. federal statutory rate primarily due to the effects of certain permanent items, foreign tax rate differences, and increases in the valuation allowance against deferred tax assets. Net Operating Loss and Credit Carryforwards As of December 31, 2021, the Company has net operating loss (“NOL”) carryforwards for U.S. federal income tax purposes, and similar state amounts, of approximately $ 195.7 million available to reduce future income subject to income taxes before limitations. As of December 31, 2021, the Company had a net operating loss carryforward for tax purposes related to its foreign subsidiary of $ 20.5 million. U.S. federal net operating carryforwards generated prior to 2018 in the approximate amount of $ 71.9 million will begin to expire, if no t utilized, in 2022. Our non-U.S. net operating loss and U.S. federal net operating losses post 2017 have an indefinite life. The Company expects $ 128.4 million of legacy Xometry U.S. federal net operating losses to be available to offset future taxable income. Management has not yet completed its evaluation of any limitations on the ability to use the acquired Thomas subsidiary net operating loss carryforward of $ 67.3 million. The Company plans to complete this analysis during the second quarter of 2022 and the results may impact the net operating loss deferred tax asset, acquisition accounting and income tax provision.

Debt Disclosure [Abstract]
Debt Commitments and Contingencies	(13) Debt Commitments and Contingencies 2027 Convertible Notes In February 2022, we entered into a purchase agreement with certain counterparties for the sale of an aggregate of $ 287.5 million principal amount of convertible senior notes due in 2027 (the “2027 Notes”) in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The 2027 Notes consisted of a $ 250 million initial placement and an over-allotment option that provided the initial purchasers of the 2027 Notes with the option to purchase an additional $ 37.5 million aggregate principal amount of the 2027 Notes, which was fully exercised. The 2027 Notes were issued pursuant to an indenture dated February 4, 2022 . The net proceeds from the issuance of the 2027 Notes were $ 278.2 million, net of debt issuance costs. The debt issuance costs are amortized to interest expense using the effective interest rate method. The 2027 Notes are unsecured obligations which bear regular interest at 1 % per annum and for which the principal balance will not accrete. The 2027 Notes will mature on February 1, 2027 unless repurchased, redeemed, or converted in accordance with their terms prior to such date. The 2027 Notes are convertible into cash, shares of our Class A common stock, or a combination of cash and shares of our Class A common stock, at our election, at an initial conversion rate of 17.8213 shares of Class A common stock per $ 1,000 principal amount of 2027 Notes, which is equivalent to an initial conversion price of approximately $ 56.11 per share of our Class A common stock. The conversion rate is subject to customary adjustments for certain events as described in the indenture governing the 2027 Notes. We may redeem for cash all or any portion of the 2027 Notes, at our option, on or after February 5, 2025 if the last reported sale price of our Class A common stock has been at least 130 % of the conversion price then in effect for at least 20 trading days at a redemption price equal to 100 % of the principal amount of the 2027 Notes to be redeemed, plus accrued and unpaid interest or additional interest, if any. Holders of the 2027 Notes may convert all or a portion of their 2027 Notes at their option prior to November 1, 2026, in multiples of $ 1,000 principal amounts, only under the following circumstances: • if the last reported sale price of our Class A common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter is greater than or equal to 130 % of the applicable conversion price of the 2027 Notes on each such trading day; • during the five business day period after any ten consecutive trading day period in which the trading price per $ 1,000 principal amount of the 2027 Notes for each day of that ten consecutive trading day period was less than 98 % of the product of the last reported sale price of our Class A common stock and the applicable conversion rate of the 2027; • on a notice of redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, in which case we may be required to increase the conversion rate for the 2027 Notes so surrendered for conversion in connection with such redemption notice; or • on the occurrence of specified corporate events. On or after November 1, 2026, the 2027 Notes are convertible at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Holders of the 2027 Notes who convert the 2027 Notes in connection with a make-whole fundamental change, as defined in the indenture governing the 2027 Notes, or in connection with a redemption are entitled to an increase in the conversion rate. Additionally, in the event of a fundamental change, holders of the 2027 Notes may require us to repurchase all or a portion of the 2027 Notes at a price equal to 100 % of the principal amount of 2027 Notes, plus any accrued and unpaid special interest, if any. We accounted for the issuance of the 2027 Notes as a single liability measured at its amortized cost, as no other embedded features require bifurcation and recognition as derivatives. The following table presents the outstanding principal amount and carrying value of the 2027 Notes as of the dates indicated (in thousands): March 31, 2022 Principal $ 287,500 Unamortized debt discount ( 8,338 ) Unamortized debt issuance costs ( 651 ) Net carrying value $ 278,511 The annual effective interest rate for the 2027 Notes was approximately 1.6 %.

Term Loan Facility The Company was party to an amended and restated loan and security agreement ("Amended Loan and Security Agreement") with Hercules Capital, Inc. (“Hercules”) for a term loan ("the Term Loan Facility"). Under the Amended Loan and Security Agreement, effective January 30, 2020, the Company could borrow up to $ 15 million under the Term Loan Facility, all of which became available to the Company immediately on the agreement date. On July 9, 2021, the Company repaid the full amount of its term loan with Hercules with proceeds from the IPO. In connection with the debt extinguishment, the Company paid Hercules $ 16.1 million and recorded a loss on debt extinguishment of approximately $ 0.3 million. Prior to its repayment, the term loan accrued interest at the greater of (i) 8.7 % per annum or (ii) 8.7 % per annum plus the prime rate minus 4.75 % per annum. The term loan agreement required a maximum $ 1.2 million end of term fee due and payable on the maturity date of May 1, 2022 , however, if the term loan was repaid prior to November 1, 2021, the amount owed would be $ 0.9 million. As part of the initial term loan agreement with Hercules, the Company issued a warrant to purchase 87,784 shares of the Company’s Series B Convertible Preferred Stock with a strike price of $ 5.13 per share that expires in May 2025 . Upon closing of the IPO on July 2, 2021, the warrant held by Hercules may only be exercised for shares of Class A common stock. Contingencies The Company from time to time may be subject to various claims and legal proceedings covering a range of matters that arise in the ordinary course of its business activities. In the opinion of the Company, although the outcome of any legal proceedings cannot be predicted with certainty, the ultimate liability of the Company in connection with its legal proceedings is not expected to have a material adverse effect on the Company’s financial position or operations.

Segment Reporting [Abstract]
Segments	(14) Segments Xometry is organized in two segments referred to as: (1) the U.S. and (2) International (formerly referred to as Europe). Xometry’s operating segments are also the Company’s reportable segments. Xometry’s reportable segments, whose products and offerings are generally the same, are managed separately based on geography. Xometry’s two segments are defined based on the reporting and review process used by the chief operating decision maker (“CODM”), the Chief Executive Officer. The Company evaluates the performance of the operating segments primarily based on revenue and segment “profits/loss” which is largely the results of the segment before income taxes. The Company has not allocated certain general and administrative expenses to the International segment. The Company’s CODM monitors assets of the consolidated Company, but does not use assets, by operating segment when assessing performance or making operating segment resource decisions. The following tables reflect certain segment information for the three months ended March 31, 2022 and 2021 (in thousands): Three Months Ended March 31, 2022 2021 Revenue U.S. $ 77,209 $ 41,299 International 6,462 2,623 Total $ 83,671 $ 43,922 Three Months Ended March 31, 2022 2021 Segment Losses U.S. $ ( 16,296 ) $ ( 8,162 ) International ( 3,699 ) ( 2,339 ) Total $ ( 19,995 ) $ ( 10,501 )

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	(a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company's Annual Report on Form 10-K filed with the SEC on March 18, 2022. The condensed consolidated balance sheet as of December 31, 2021, included herein, was derived from the audited financial statements as of that date, but may not include all disclosures including certain notes required by U.S. GAAP on an annual reporting basis. In the opinion of management, the accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss, stockholders' equity (deficit) and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year 2022 or any future period. The Company has two reporting segments which are referred to as: (1) the United States (“U.S.”) and (2) International. Foreign Operations and Comprehensive Loss The U.S. dollar (“USD”) is the functional currency for Xometry’s consolidated subsidiary operating in the U.S. The primary functional currency for the Company's consolidated subsidiaries operating in Germany and to a lesser extent Japan is the Euro ("Euro") and the Yen, respectively. For the Company’s consolidated subsidiaries whose functional currencies are not the USD, the Company translates their financial statements into USD. The Company translates assets and liabilities at the exchange rate in effect as of the financial statement date. Revenue and expense accounts are translated using an average exchange rate for the period. Gains and losses resulting from translation are included in accumulated other comprehensive income (“AOCI”), as a separate component of equity. Noncontrolling Interest In connection with the acquisition of Thomas on December 9, 2021, we assumed a 66.67 % ownership in Incom Co., LTD. As we have a controlling interest in Incom Co., LTD, we have consolidated Incom Co., LTD into our financial statements. The portion of equity in Incom Co., LTD not owned by the Company is accounted for as a noncontrolling interest. We present the portion of any equity that we do not own in a consolidated entity as noncontrolling interest and classify their interest as a component of total equity, separate from total stockholders’ equity (deficit) on our Condensed Consolidated Balance Sheets. We include net income (loss) attributable to the noncontrolling interests in net income (loss) in our Condensed Consolidated Statements of Operations and Comprehensive Loss.
Use of Estimates	(b) Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates. In light of the currently unknown duration and severity of the COVID-19 pandemic, we face a greater degree of uncertainty than normal in making the judgments and estimates needed to apply our significant accounting policies. As of the date these condensed consolidated financial statements were issued, the impacts of the COVID-19 pandemic did not have a significant impact on our estimates or judgments. Judgments and assumptions may change, as new events occur and additional information is obtained, as well as other factors related to COVID-19 and economic recovery that could result in a meaningful impact on our consolidated financial statements in future reporting periods.
Business Combinations	(c) Business Combinations The Company accounts for business combinations using the acquisition method of accounting, which requires, among other things, allocation of the fair value of purchase consideration to the tangible and intangible assets acquired and liabilities assumed at their estimated fair values on the acquisition date. The excess of the fair value of purchase consideration over the values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair value of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to the valuation of intangible assets. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed, with a corresponding offset to goodwill if new information is obtained related to facts and circumstances that existed as of the acquisition date. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are reflected in the condensed consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred.
Fair Value Measurements and Financial Instruments	(d) Fair Value Measurements and Financial Instruments The Company measures certain assets and liabilities at fair value on a recurring basis based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis, whereby inputs used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Inputs reflect quoted prices for identical assets or liabilities in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 - Unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. The carrying amounts of certain of the Company’s financial instruments, which include cash and cash equivalents, accounts receivable, prepaid expenses and other assets, accounts payable, accrued expenses and contract liabilities approximate their fair values due to their short maturities. The Company's marketable securities are recorded at fair value.
Marketable Securities	(e) Marketable Securities The Company measures its marketable securities at fair value and recognizes any changes in fair value in net loss. Our marketable securities represent our investment in a short term bond fund and a money market fund. We consider our marketable securities as available for use in current operations, and therefore classify these securities as current assets on the Condensed Consolidated Balance Sheets. As of March 31, 2022 and December 31, 2021, the Company's marketable securities of $ 309.7 million and $ 30.5 million, respectively were recorded at fair value, within Level 1 of the fair value hierarchy. The fair value of the Company’s Level 1 financial instruments is based on quoted prices in active markets, total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs, discounts or blockage factors. During the three months ended March 31, 2022, the Company recorded an unrealized loss of $ 0.9 million related to these securities which is recorded in other expenses on the Condensed Consolidated Statements of Operations and Comprehensive Loss. No unrealized gains (losses) were recorded during the three months ended March 31, 2021.
Accounts Receivable	(f) Accounts Receivable Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. For buyers for which Xometry provides credit, the Company performs credit inquiries, including references checks, and queries credit ratings services and other publicly available information. Amounts collected on accounts receivable are included in net cash provided by operating activities in the statements of cash flows. Management provides for probable uncollectible amounts through a provision for bad debt expense and an adjustment to a valuation allowance based on its experience and judgment. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.
Property and Equipment and Long-Lived Assets	(g) Property and Equipment and Long-Lived Assets Property and equipment are stated at cost. Equipment under finance leases is stated at the present value of minimum lease payments. Depreciation is calculated on the straight-line method over the estimated useful life of the assets, which range from three to seven years , or in the case of leasehold improvements, over the shorter of the remaining lease term or the useful life of the asset. Property and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary. Property and equipment includes capitalized internal-use software development costs. Eligible internal-use software development costs are capitalized subsequent to the completion of the preliminary project stage. Such costs include internal and external direct development costs totaling $ 2.2 million for the three months ended March 31, 2022 and $ 5.2 million for the year ended December 31, 2021. After all substantial testing and deployment is completed and the software is ready for its intended use, capitalization is discontinued and the internal-use software costs are placed in service and amortized using the straight-line method over the estimated useful life of the software, generally three years.
Revenue	(h) Revenue The Company derives the majority of its marketplace revenue in the U.S. and Europe from the sale of parts and assemblies fulfilled using a vast network of suppliers. The Company recognizes revenue from the sales to our customers pursuant to Financial Accounting Standard Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”). The Company determines that a contract exists between the Company and the customer when the customer accepts the quote and places the order, all of which are governed by the Company’s standard terms and conditions or other agreed terms with Xometry’s buyers. Upon completion of an order through Xometry’s platform, the Company identifies the performance obligation(s) within that order to complete the sale of the manufactured part(s) or assembly. Using Xometry’s in-house technology, the Company determines the price for the manufactured part(s) or assembly on a stand-alone basis at order initiation. The Company recognizes revenue from sales to Xometry’s customers upon shipment, at which point control over the part(s) or assembly have transferred. The Company has concluded that the Company is principal in the sale of part(s) and assemblies that use the Company’s network of third-party manufacturers because the Company controls the manufacturing by obtaining a right to direct a third-party manufacturer to fulfill the performance obligation Xometry has with the Company’s customers on Xometry’s behalf. The Company has considered the following conditions of the sale: (i) the Company has the obligation of providing the specified product to the customer, (ii) the Company has discretion with respect to establishing the price of the product and the price the Company pays the suppliers and the Company has margin risk on all of Xometry’s sales, (iii) the Company has discretion in determining how to fulfill each order, including selecting the supplier and (iv) Xometry bears certain risk for product quality to the extent the customer is not satisfied with the final product. Xometry also derives revenue from its supplier services which is a suite of services offered to our suppliers. In connection with the acquisition of Thomas on December 9, 2021, our revenue also includes the sale of advertising. This revenue is generally recognized as control is transferred to the customer, in an amount reflecting the consideration we expect to be entitled to in exchange for such product or service. A purchase order with a customer may involve multiple performance obligations, including a combination of some or all of our products. Judgment may be required in determining whether products are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation. Revenue is recognized over the period or at the point in time in which the performance obligations are satisfied. Consideration is typically determined based on a fixed unit price for the quantity of product transferred. For purchase orders involving multiple performance obligations, the transaction price is allocated to each performance obligation based on relative standalone selling price, and recognized as revenue when each individual product or service is transferred to the customer. Revenue is shown net of estimated returns, refunds, and allowances. As of March 31, 2022 and December 31, 2021, the Company has a $ 0.3 million and $ 0.2 million, respectively, provision for estimated returns, refunds or allowances. Sales tax collected from customers and remitted to governmental authorities is excluded from revenue. Contract Liabilities Contract liabilities are primarily derived from payments received in advance or at the time an order is placed, for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria described above. The following table is a summary of the contract liabilities as of December 31, 2021 and March 31, 2022 (in thousands): Contract liabilities at December 31, 2021 $ 7,863 Revenue recognized ( 36,958 ) Payments received in advance 39,103 Contract liabilities at March 31, 2022 $ 10,008 During the period ended March 31, 2022, the Company recognized approximately $ 7.2 million of revenue related to its contract liabilities at December 31, 2021. Sales Contract Acquisition Costs The Company’s incremental costs to obtain a contract may include a sales commission which is generally determined on a per order basis. For contracts in excess of one year, the Company amortizes such costs on a straight-line basis over the average customers life of two years for new customers and over the renewal period for existing customers which is generally one year . Sales commissions are included in Xometry’s sales and marketing expenses and cost of revenue in the Condensed Consolidated Statements of Operations and Comprehensive Loss. For the three months ended March 31, 2022, we recognized approximately $ 2.2 million of amortization related to deferred sales commissions.
Cost of Revenue	(i) Cost of Revenue Cost of revenue for marketplace primarily consists of the cost of the products that are manufactured or produced by the Company’s suppliers for delivery to buyers on the Company's platform, internal and external production costs, shipping costs, and certain internal depreciation. Cost of revenue for supplier services primarily consists of internal and external production costs and website hosting.
Leases	(j) Leases The Company determines if an arrangement contains a lease and the classification of that lease, if applicable, at its inception. Operating leases are included in operating lease right-of-use ("ROU") assets, operating lease liabilities and operating lease liabilities (net of current portion) in the Condensed Consolidated Balance Sheets. The Company has finance leases as detailed in the Long-Lived Assets section above. For leases with terms of twelve months or less, the Company does not recognize a ROU assets or lease liabilities on the Condensed Consolidated Balance Sheets. Additionally, the Company elected to use the practical expedient to not separate lease and non-lease components for leases of real estate, meaning that for these leases, the non-lease components are included in the associated ROU asset and lease liability balances on the Company’s Condensed Consolidated Balance Sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments under the lease. Operating lease ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within the Company’s operating leases is generally not determinable, as such the Company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of the Company’s leases include options to extend or terminate the lease. The expected lease term includes options to extend or terminate the lease when it is reasonably certain the Company will exercise such option. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.
Sales and Marketing	(k) Sales and Marketing Sales and marketing expenses are expensed as incurred and include the costs of digital marketing strategies, branding costs and other advertising costs, certain depreciation and amortization expense, and compensation expenses, including stock-based compensation, to the Company’s sales and marketing employees. For the three months ended March 31, 2022 and 2021, the Company’s advertising costs were $ 7.1 million and $ 4.2 million, respectively.
Operations and Support	(l) Operations and Support Operations and support expenses are the costs the Company incurs in support of buyers and suppliers on Xometry’s platforms which are provided by phone, email and chat for purposes of resolving buyer and supplier related matters. These costs primarily consist of compensation expenses of the support staff, including stock-based compensation, certain depreciation and amortization expense and software costs used in delivering buyer and supplier services.
Product Development	(m) Product Development Product development costs which are not eligible for capitalization are expensed as incurred. This account also includes compensation expenses, including stock-based compensation to the Company’s employees performing these functions and certain depreciation and amortization expense.
General and Administrative	(n) General and Administrative General and administrative expenses primarily consist of professional service fees and certain depreciation and amortization expense. It also includes compensation expenses, including stock-based compensation expenses, for executive, finance, legal and other administrative personnel.
Stock Based Compensation	(o) Stock Based Compensation All stock based compensation, including stock options and restricted stock units are measured at the grant date fair value of the award. The Company estimates grant date fair value of stock options using the Black-Scholes option-pricing model. The fair value of stock options and restricted stock units is recognized as compensation expense on a straight-line basis over the requisite service period, which is typically four years . The fair value of the restricted stock units is determined using the fair value of the Company's Class A common stock on the date of grant. Forfeitures are recorded in the period in which they occur. The Black-Scholes model considers several variables and assumptions in estimating the fair value of stock-based awards. These variables include: • expected annual dividend yield; • expected volatility over the expected term; • expected term; • risk free interest rate; • per share value of the underlying common stock; and • exercise price. For all stock options granted, the Company calculated the expected term using the simplified method for “plain vanilla” stock option awards. The risk-free interest rate is based on the yield available on U.S. Treasury issuances similar in duration to the expected term of the stock-based award. As there was no public market for the Company's common stock prior to the initial public offering (“IPO”), the Company estimates its expected share price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. The Company utilized a dividend yield of zero, as it had no history or plan of declaring dividends on its common stock.
Net Loss Per Share	(p) Net Loss Per Share Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. The diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the period. For periods in which the Company reports net losses, diluted net loss per common share is the same as basic net loss per common share, because all potentially dilutive securities are anti-dilutive. Vested RSUs that have not been settled have been included in the appropriate common share class used to calculate basic net loss per share. Subsequent to the Company's IPO on July 2, 2021, the Company computes net loss per share using the two-class method required for multiple classes of common stock and participating securities. The two-class method requires income available to common stockholders for the period to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the period had been distributed. Certain unvested share-based payment awards that contain nonforfeitable rights to dividends are treated as participating securities and therefore included in computing net income per share using the two-class method. The rights, including the liquidation and dividend rights, of the Class A common stock and Class B common stock are substantially identical, other than voting rights. Accordingly, the Class A common stock and Class B common stock shared proportionately in the Company’s net losses.
Recently Issued Accounting Standards	Recently Issued Accounting Standards New Accounting Pronouncements Effective in the Period Ended March 31, 2022 In August 2020, the FASB issued Accounting Standards Update (“ASU”) 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”) , which reduced the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that would have previously been accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. We adopted ASU 2020-06 on January 1, 2022 . As a result of the adoption of ASU 2020-06, the convertible notes issued in February 2022 were considered to be debt with no allocation to equity. New Accounting Pronouncements Effective in Future Periods In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (“Topic 326”), Measurement of Credit Losses on Financial Instruments . Topic 326 changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assets and net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowance for credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Topic 326 is effective as of January 1, 2023. Early adoption is permitted. The Company is currently evaluating the impact of Topic 326 on its consolidated financial statements and related disclosures. There are currently no other accounting standards that have been issued, but not yet adopted, that are expected to have a significant impact on the Company’s consolidated financial position, results of operations or cash flows upon adoption.
