Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	(1) Organization and Description of Business Xometry, Inc. (“Xometry”, the “Company”, “we”, or “our”) was incorporated in the State of Delaware in May 2013 . Xometry uses proprietary technology to enable product designers, engineers, buyers, and supply chain professionals to instantly access the capacity of a global network of manufacturing facilities. The Company’s platform makes it possible for customers to quickly receive pricing, expected lead times, manufacturability feedback and place orders on the Company’s platform. The network allows the Company to provide high volumes of unique parts, including custom components and aftermarket parts for its customers. Xometry's corporate headquarters is located in Derwood, Maryland. Xometry’s seller capabilities include computer numerical control manufacturing, sheet metal manufacturing, 3D printing (including fused deposition modeling, direct metal laser sintering, PolyJet, stereolithography, selective laser sintering, binder jetting, carbon digital light synthesis and multi jet fusion), die casting, injection molding, urethane casting, as well as finishing services, rapid prototyping and high-volume production. On November 1, 2021, the Company acquired certain assets and liabilities from Big Blue Saw LLC ("Big Blue Saw"), subject to an Asset Purchase Agreement for total consideration of $ 2.5 million. The total consideration includes cash consideration at closing of $ 1.25 million, $ 250,000 of Class A common stock at closing and contingent consideration up to $ 1.0 million. Big Blue Saw extends our marketplace capabilities in water jet and laser cutting. On November 5, 2021, the Company acquired certain assets and liabilities from Fusiform, Inc. (d.b.a FactoryFour), subject to an Asset Purchase Agreement for total consideration of $ 6.3 million. The total consideration includes cash consideration at closing of $ 1.9 million, $ 1.9 million of Class A common stock at closing and contingent consideration up to $ 2.5 million. FactoryFour provides a SaaS based solution to help manufacturers in the Xometry marketplace improve lead times and make strong, data-driven decisions through real-time production tracking. On December 7, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Thomas Publishing Company, a New York corporation (“Thomas”), NAASOM Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of the Company (“Merger Sub”), and Shareholder Representative Services LLC, as the shareholders’ representative thereunder. Pursuant to the Merger Agreement, Merger Sub merged with and into Thomas, with Thomas continuing as the surviving corporation and becoming a wholly owned subsidiary of the Company (the “Acquisition”), effective December 9, 2021. The aggregate consideration payable in exchange for all of the outstanding equity interests of Thomas was $ 300 million subject to customary adjustments as set forth in the Merger Agreement, payable in cash and shares of the Company’s Class A common stock. The Company paid approximately $ 198.5 million of cash and issued 2,073,422 shares of the Company’s Class A common stock to holders of Thomas shares. The acquisition of Thomas is expected to expand Xometry’s buyer and seller base, enhancing Xometry’s global digital marketplace for manufacturers. Xometry also expects to leverage Thomas’ marketing and data services to deliver a suite of end-to-end services for sellers with additional financial services and digital marketing products. The financial results of Big Blue Saw, FactoryFour and Thomas have been included in our consolidated financial statements from the date of acquisition. See “Note 13—Acquisitions.” Initial Public Offering On July 2, 2021, the Company closed its planned initial public offering ("IPO"), in which it issued and sold 7,906,250 shares of its Class A common stock. The initial offering price was $ 44.00 per share. The Company received net proceeds of approximately $ 325.3 million from the IPO after deducting underwriting discounts and commissions of $ 22.6 million. The Company also incurred approximately $ 3.7 million of other offering costs in connection with its IPO. Upon the closing of the IPO on July 2, 2021, 8,665,797 shares of outstanding common stock were reclassified into Class A common stock, 27,758,941 shares of outstanding convertible preferred stock were converted into Class A common stock, and 2,676,154 shares of Class A common stock were exchanged by our co-founders for an equivalent number of shares of Class B common stock pursuant to the terms of the exchange agreement. Also on July 2, 2021, the Company reserved 402,658 shares of its Class A common stock, representing 1 % of the Company's fully diluted capitalization as of the date of approval by our board of directors, for charitable contributions to non-profit organizations. These shares will be issued over the next five years, in an amount not to exceed 20 % of the initial reserve amount per calendar year. During 2021, the Company donated 40,266 shares of Class A common stock to a donor advised fund and recognized an expense associated with the charitable contribution of approximately $ 2.2 million which is recorded in general and administrative expense in the Consolidated Statements of Operations and Comprehensive Loss.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies (a) Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Xometry and its subsidiaries. All intercompany transactions and balances have been eliminated. The accompanying consolidated financial statements and related disclosures are presented in accordance with U.S. generally accepted accounting principles ("GAAP"). 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 since December 9, 2021. 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 consolidated entity as noncontrolling interest and classify their interest as a component of total equity, separate from total stockholders’ equity (deficit) on our Consolidated Balance Sheets. We include net income (loss) attributable to the noncontrolling interests in net income (loss) in our Consolidated Statements of Operations and Comprehensive Loss. (b) Reclassifications Certain line items on the Company’s consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have not changed the results of operations of prior periods. (c) Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with 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 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. (d) 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 consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred. (e) 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. (f) Cash and Cash Equivalents Cash and cash equivalents consist of cash held in checking accounts and investments in money market funds. The Company considers all highly liquid securities purchased with an initial maturity of three months or less to be cash equivalents. These investments are stated at cost, which approximates fair value. (g) 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 the short term bond fund. We consider our marketable securities as available for use in current operations, and therefore classify these securities as current assets on the Consolidated Balance Sheets. As of December 31, 2021, the Company's marketable securities of $ 30.5 million 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 period from August 2021 through December 31, 2021, the Company recorded an unrealized loss of $ 2.0 million related to these securities which is recorded in other expenses on the Consolidated Statements of Operations and Comprehensive Loss. (h) Accounts Receivable Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. For customers for which Xometry provides credit, the Company performs credit inquiries, including references checks, and query 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. (i) Inventory Inventory consists primarily of work-in-progress, raw materials and tools. Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory for slow-moving, damaged and discontinued items and provides allowances to reduce such items identified to their recoverable amounts, if needed. (j) 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 year s, 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 $ 5.2 million and $ 3.6 million for the years ended December 31, 2021 and 2020, respectively. 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. (k) Investment In Unconsolidated Joint Venture We account for our investment in unconsolidated joint venture using the equity method of accounting as we exercise significant influence, but do not control the entity. Under the equity method of accounting, the net equity investments of the Company are reflected in the accompanying Consolidated Balance Sheets and the Company’s share of net income from the joint venture is included in the accompanying Consolidated Statements of Operations and Comprehensive Loss. On a periodic basis, management assesses whether there are any indicators that the value of the Company’s investment in the unconsolidated joint venture may be other-than-temporarily-impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such a decline in value is deemed to be other than-temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. This evaluation consists of several qualitative and quantitative factors including recent financial results and operating trends of the investee and available information that may affect the value of our investment. No impairment loss on our investment in unconsolidated joint venture was recognized during the year ended December 31, 2021. (l) Revenue The Company derives substantially all of its revenue in the U.S. and Europe from the sale of parts and assemblies fulfilled using a vast network of manufacturers. The Company recognizes revenue from the sales to its buyers 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 customers. 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 customer 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 sellers 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 seller and (iv) Xometry bears certain risk for product quality to the extent the buyer is not satisfied with the final product. In connection with the acquisition of Thomas on December 9, 2021, our revenue also includes the sale of internet 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. A purchase order with a customer may involve multiple performance obligations, including a combination of some or all of the 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 is transferred to the customer. Revenue is shown net of estimated returns, refunds, and allowances. At December 31, 2021, the Company has a $ 0.2 million provision for estimated returns, refunds or allowances. At December 31, 2020, the Company has a $ 0.1 million 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 derived from payments received 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 (in thousands): Contract liabilities at December 31, 2019 $ 1,821 Revenue recognized ( 67,450 ) Payments received in advance 67,984 Contract liabilities at December 31, 2020 $ 2,355 Acquired contract liabilities 6,634 Revenue recognized ( 126,997 ) Payments received in advance 125,871 Contract liabilities at December 31, 2021 $ 7,863 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 customer 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 Consolidated Statements of Operations and Comprehensive Loss. For the period from December 9, 2021 through December 31, 2021, we recognized approximately $ 0.5 million of amortization related to deferred sales commissions. (m) Cost of Revenue Cost of revenue primarily consists of the cost of the products that are manufactured or produced by the Company’s sellers for delivery to buyers on the Company's platforms, internal and external production costs, shipping costs, and certain internal depreciation. (n) 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 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 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 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. (o) 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 years ended December 31, 2021 and 2020, the Company’s advertising costs were $ 20.7 million and $ 12.0 million, respectively. (p) Operations and Support Operations and support expenses are the costs the Company incurs in support of the customers and sellers on Xometry’s platforms which are provided by phone, email and chat for purposes of resolving customer and seller 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 customer and seller service. (q) 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. (r) 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. (s) 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 issues 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 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. (t) Net Loss Per Share Attributable to Common Stockholders 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 year. The diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the year. For the years 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 year to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the year 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 share proportionately in the Company’s net losses. (u) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. To the extent that it is not considered to be more likely than not that a deferred tax asset will be realized, a valuation allowance is established. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained and are measured at the largest amount that is greater than 50% likely of being realized. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. Changes in recognition or measurement are reflected in the year in which the change in judgment occurs. (v) Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. (w) Intangible Assets Intangible assets are carried at cost and amortized on a straight-line basis over their estimated useful lives, which range from one to 15 years . Xometry reviews definite-lived intangible assets for impairment under the long-lived asset model described in Property and Equipment and Long-Lived Assets above. (x) Goodwill Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is not amortized. The Company test goodwill for impairment annually in the fourth quarter, or more frequently, if needed, and when there is a triggering event (e.g., a deterioration in general economic conditions or in the environment in which Xometry operates). When impairment indicators are identified the Company compares each reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between each reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. Xometry determines the fair value of each reporting unit using an income approach. Under the income approach, the Company based fair value on estimated discounted future cash flows of each reporting unit. Determining the fair value of each reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates and EBITDA margins, discount rates and future market conditions, among others (Level 3). (y) Recently Issued Accounting Standards New Accounting Pronouncements Effective in the Year Ended December 31, 2021 In October 2021, the FASB issued a new accounting standard on the topic of business combinations, accounting for contract assets and contract liabilities from contracts with customers, Accounting Standard Update ("ASU") 2021-08, Business Combinations (Topic 805). The amendment in this update improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency. This update requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. The guidance is effective for interim and annual periods beginning after December 15, 2022 with early adoption permitted. The Company adopted ASU 2021-08 on November 1, 2021 . In connection with the Company's business combinations during the fourth quarter of 2021, the Company recognized its acquired contract asset and liabilities in accordance with ASC 606. 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.

Equity [Abstract]
Common Stock	(7) Common Stock Prior to the Company's IPO on July 2, 2021, holders of common stock were entitled to one vote per share , receive dividends and, upon liquidation or dissolution, were entitled to receive all assets available for distribution to stockholders. The holders had no preemptive or other subscription rights and there were no redemption or sinking fund provisions with respect to such shares. Common stock was subordinate to the preferred stock with respect to dividend rights, rights upon liquidation, and dissolution of the Company. In connection with the Company's IPO on July 2, 2021, the 8,665,797 shares of common stock outstanding on June 30, 2021 were reclassified to Class A common stock. Of those 8,665,797 shares of common stock, 2,268,846 were exchanged for Class B common stock. On July 2, 2021, the Company amended and restated its certificate of incorporation to provide for two classes of common stock: Class A common stock and Class B common stock. The Company's authorized capital stock consists of 805 million shares, all with a par value of $ 0.000001 per share, of which: • 750,000,000 are designated Class A common stock; • 5,000,000 are designated Class B common stock; and • 50,000,000 are designated preferred stock. Shares of Class A common stock and Class B common stock have the same rights and privileges and rank equally, share ratably and are identical in all respects, including but not limited to dividends and distributions, liquidation rights, change of control transactions, subdivisions and combinations, no preemptive or similar rights, and conversion.

Of those 27,758,941 shares of Convertible Preferred Stock, 407,308 were exchanged for Class B common stock. During 2020, certain Series A-2, B, C and D Convertible Preferred stockholders planned to sell their Convertible Preferred Stock to a third party. The Company exercised its right of first refusal to reacquire these shares of Convertible Preferred Stock from these certain stockholders at the same price the third party was willing to pay for such shares of Convertible Preferred Stock. In conjunction with the Series E offering, the Company sold the same shares of Series A-2, B, C and D Convertible Preferred Stock to the Series E investors for the same price that the Company paid to acquire such shares of Convertible Preferred Stock. The Company recorded an $ 8.8 million deemed dividend to the selling stockholders, which represents the excess of the purchase price of the shares of Convertible Preferred Stock purchased by the Company over the original cost of the shares and was recorded in additional paid-in-capital and accumulated deficit.

(b) Dividends The holders of the Convertible Preferred Stock and the holders of the shares of common stock were entitled to receive dividends, when, as and if declared by the Board of Directors of the Company, out of any assets legally available therefore, on an as-converted basis. Prior to the payment of any dividend to the holders of common stock (other than dividends of common stock), the Company was required to pay a dividend on each outstanding share of Convertible Preferred Stock equal to 8 % of the applicable original issue price of such share of Convertible Preferred Stock, having accrued from the date the first share of Series E Convertible Preferred Stock was issued. Dividends are not mandatory or cumulative and no rights or interest shall accrue to the holders of Convertible Preferred Stock and common stock, unless declared. (c) Conversion Each share of Convertible Preferred Stock was convertible, at the option of the holder, into one share of common stock, as determined by dividing its issuance price per share by the applicable conversion price, subject to adjustments. Each share of Convertible Preferred Stock would automatically convert into common stock upon either (i) closing of a public offering with gross proceeds of at least $ 50 million and the purchase price of such shares is at least $ 20.43 per share or (ii) written consent of the holders of a majority of the outstanding shares of Convertible Preferred Stock electing such a conversion, provided, however, that the conversion of the Series D Convertible Preferred Stock and Series E Convertible Preferred Stock required the vote or written consent of a majority of the outstanding shares of Series D Convertible Preferred Stock and Series E Convertible Preferred Stock, respectively. (d) Liquidation and Share Preference In the event of any liquidation, dissolution or winding up of the Company, either voluntary or involuntary, the holders of the Convertible Preferred Stock, on a pari passu basis, were entitled to liquidation preference equal to the original purchase price plus declared and unpaid dividends. After payment of the amounts above, if assets or funds remain in the Company, all remaining assets and funds were to be distributed pro rata among holders of common stock. (e) Redemption The holders of Convertible Preferred Stock had no voluntary rights to redeem their shares. The Convertible Preferred Stock had deemed liquidation provisions which require the shares to be redeemed upon a change in control or other deemed liquidation events. Although the Convertible Preferred Stock was not mandatorily or currently redeemable, a deemed liquidation event would constitute a redemption event outside the Company’s control. As a result of these liquidation features, all shares of Convertible Preferred Stock were classified outside of stockholders’ deficit as temporary equity on the Consolidated Balance Sheets. The carrying values of the Company’s Convertible Preferred Stock have not been accreted to their redemption values as these events are not considered probable of occurring. Subsequent adjustments of the carrying values to redemption values would be made only if and when it became probable the preferred shares would become redeemable.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock Based Compensation	(9) 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"), non-statutory 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. The maximum number of shares of common stock that may be issued under the Company's 2021 Plan is 4,026,588 shares. As of December 31, 2021, there were 3,838,154 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. The weighted average assumptions for the year ended December 31, 2021 and December 31, 2020 are provided in the following table.

In the second quarter of 2021, the Company assessed the fair value of the Company's April 2021 stock option grant, giving consideration to the Company's initial public offering price of $ 44.00 per share. The Company assumed a $ 28.00 per share fair value, which was based on a 30 % discount from the midpoint of our initial price range, in order to determine the appropriate stock-based compensation expense for financial reporting purposes. The Company estimated that the fair value of the April 2021 grants approximated $ 25.6 million which is being recognized over 4 years from the grant date. The total intrinsic value of options exercised during the years ended December 31, 2021 and 2020 was $ 19.0 million and $ 1.6 million, respectively. At December 31, 2021 and 2020, there was $ 21.4 million and $ 2.4 million, respectively, of total unrecognized compensation cost related to unvested stock options granted under the 2016 Equity Incentive Plan.

Income Tax Disclosure [Abstract]
Income Taxes	(10) Income Taxes The Company had no current or deferred income tax benefit or expense in the U.S. or outside the U.S. for the years ended December 31, 2021, 2020 and 2019. The reconciliation of the statutory federal income tax rate to the Company’s effective tax rate was as follows: Year Ended December 31, 2021 2020 2019 Federal tax statutory rate 21 % 21 % 21 % Foreign rate difference 1 3 — Permanent difference: stock based compensation 1 — — Permanent difference: other ( 1 ) — — Goodwill impairment — ( 2 ) ( 1 ) Valuation allowance ( 22 ) ( 22 ) ( 20 ) — % — % — % Under GAAP, changes in tax rates and tax law are accounted for in the period of enactment and deferred tax assets and liabilities are measured at the enacted tax rate. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities at December 31, 2021 and 2020 are presented below (in thousands): December 31, 2021 2020 Deferred tax assets: Deferred compensation $ 2,403 $ 698 Leases 3,587 509 Sec. 163(j) interest limitation carryforward 526 390 Allowance for doubtful accounts 424 141 Fixed assets 240 — Charitable contributions 548 — Unrealized losses 501 — Other 530 16 Net operating loss 54,570 25709 Total deferred tax assets 63,329 27,463 Less valuation allowance ( 47,310 ) ( 26,148 ) Total deferred tax assets, net $ 16,019 $ 1,315 Deferred tax liabilities: Fixed assets $ — $ ( 227 ) Leases ( 4,729 ) ( 457 ) Deferred sales commissions ( 1,406 ) — Acquisition costs and intangibles ( 9,884 ) ( 631 ) Total deferred tax liabilities ( 16,019 ) ( 1,315 ) Net deferred tax asset/liability $ — $ — Tax Valuation Allowance In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible. Management considers scheduled reversals of deferred tax liabilities, projecting future taxable income, and tax planning strategies that can be implemented by the Company in making the assessment. As of December 31, 2021, and 2020, the Company had a valuation allowance of $ 47.3 million and $ 26.1 million, respectively, against certain deferred tax assets. The valuation allowance relates to the deferred tax assets of the Company’s U.S. entities, including federal and state tax attributes and timing differences, as well as the deferred tax assets of its foreign subsidiaries. The increase in the valuation allowance during 2021 is primarily related to the pre-tax losses generated in the U.S and non-U.S. operations. The Company has a full valuation allowance against its net deferred tax assets as a result of cumulative losses as of December 31, 2021 and 2020. 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 subsidiaries 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. Under the provisions of U.S. Internal Revenue Code Section 382, certain substantial changes in the Company’s ownership may result in a limitation in the amount of U.S. net operating loss carryforwards that can be utilized annually to offset future taxable income . As of December 31, 2021 the $ 195.7 million of U.S. federal net operating losses excludes $ 14.7 million of Maketime Inc. acquired net operating losses that the Company expects to be substantially limited by Section 382 of the U.S. Internal Revenue Code and does not expect to claim on a U.S. Tax Return. As of December 31, 2021, the Company completed its analysis on Xometry's legacy $ 128.4 million U.S. federal net operating losses, pursuant to Section 382 of the U.S. Internal Revenue Code, to determine the impact ownership changes have had on the ability of the Company to utilize net operating losses it has generated. Based on the results of this analysis, 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 2022 and the results could have a significant impact on the net operating loss deferred tax asset, acquisition accounting and income tax provision. Uncertain Tax Positions For uncertain tax positions, the Company uses a more-likely-than-not recognition threshold based on the technical merits of the tax position taken. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefits determined on a cumulative probability basis, which are more-likely-than-not to be realized upon ultimate settlement in the financial statements. Our gross unrecognized tax benefits related to uncertain tax positions as of December 31, 2021 and 2020 were $ 1.1 million and zero , respectively, which were included in income taxes payable on our consolidated balance sheets. If recognized, the resulting tax benefit would impact our effective tax rates in future effected periods. The aggregate changes in the gross unrecognized tax benefits related to uncertain tax positions were as follows (in thousands): 2021 2020 Balance as of January 1: $ — $ — Increase for tax positions due to acquisition 1,145 — Net tax position as of December 31, $ 1,145 $ — The Company’s federal and state income tax returns are subject to examination by income taxing authorities, generally for three years after the returns are filed. However, tax attribute carryforwards may still be adjusted upon examination by tax authorities. The Company is not currently under examination by any tax jurisdiction. As of December 31, 2021 and 2020, we had accrued interest expense related to uncertain tax positions of $ 0.4 million and zero , respectively. As of December 31,2021 and 2020, we have accrued penalty expense of $ 0.4 million and zero , respectively.

Debt Commitments and Contingencies	(12) Debt Commitments and Contingencies 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 (see Note 1). 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 of December 31, 2020, the Company owed $ 15.8 million on this term loan, including principal borrowings and accrued end of term fee. 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. The Term Loan Facility contained customary affirmative and negative covenants, including covenants that required Hercules consent to, among other things, merge or consolidate or acquire assets outside the ordinary course of business, make investments, incur additional indebtedness or guarantee indebtedness of others, pay dividends and redeem and repurchase the Company’s capital stock, enter into transactions with affiliates outside the ordinary course of business, and create liens on Company assets. Xometry was in compliance with covenants at the time the term loan was repaid and as of December 31, 2020. Paycheck Protection Program In April 2020, the Company received loan proceeds in the amount of approximately $ 4.8 million under the Paycheck Protection Program (“PPP”). The PPP, established as part of the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) enacted March 27, 2020, provides for loans to qualifying businesses for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business. The Company paid back the loan principal with interest on July 8, 2020. 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.

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 goodwill of $ 2.1 million arising from the acquisition of Big Blue Saw related to certain expected synergies which includes improved pricing capabilities. This goodwill which is included in our U.S. reporting segment is expected to be deductible for tax purposes. 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 includes 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 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) probably weighted assumptions about client conversions. The Company has performed a preliminary valuation analysis of the fair market value of the acquired assets and liabilities of Big Blue Saw. 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. The following table (in thousands) summarizes the consideration paid for Big Blue Saw and the preliminary fair value of the assets acquired and liabilities assumed on the acquisition date: Consideration: Cash $ 1,201 Fair value of Class A common stock 250 Fair value of contingent consideration 859 Fair value of consideration 2,310 Acquisition costs included in general and administrative 17 Recognized amounts of identifiable assets acquired and liabilities assumed: Current assets 125 Property and equipment 206 Right-of-use asset 105 Lease liability ( 105 ) Current liabilities ( 109 ) Total identifiable net assets assumed 222 Goodwill 2,088 Total $ 2,310 On November 5, 2021, the Company acquired FactoryFour subject to an Asset Purchase Agreement.

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 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. The Company has performed a preliminary valuation analysis of the fair market value of the acquired assets and liabilities of FactoryFour. 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. The following table (in thousands) summarizes the consideration paid for Factory Four and the preliminary fair value of the assets acquired and liabilities assumed on the acquisition date: Consideration: Cash $ 2,167 Fair value of Class A common stock 1,139 Fair value of contingent consideration 1,470 Fair value of consideration 4,776 Acquisition costs included in general and administrative 18 Recognized amounts of identifiable assets acquired and liabilities assumed: Current assets 234 Property and equipment 28 Intangible asset - developed technology 140 (1) Right-of-use asset 1,044 Lease liability ( 1,044 ) Current liabilities ( 658 ) Total identifiable net assets assumed ( 256 ) Goodwill 5,032 Total $ 4,776 (1) The useful life of the acquired developed technology is 3 years. The acquisitions of Big Blue Saw and FactoryFour were not considered material individually or in the aggregate to the Company for the periods presented, and therefore, proforma information has not been presented. On December 9, 2021, the Company acquired Thomas subject to the Merger Agreement. Xometry expects to leverage Thomas’ marketing and data services to deliver a suite of end-to-end services for sellers with additional financial services and digital marketing products. The Company accounted for the acquisition as a business combination. The goodwill of $ 246.7 million arising from the acquisition of Thomas related to certain expected synergies which includes the ability to drive buyers and seller onto 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 has performed a preliminary valuation analysis of the fair market value of the acquired assets and liabilities of Thomas. 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. 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 5,661 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 ) 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 29,599 Goodwill 246,738 Total $ 276,337 The following table (in thousands) summarizes the fair value of th e 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. For the year ended December 31, 2021, Thomas contributed revenue of $ 4.1 million, which is reflected in the accompanying Consolidated Statement of Operations and Comprehensive Loss. Of the $ 5.7 million of transaction costs, $ 4.5 million of underwriters fees are included in accounts payable as of December 31, 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, 2020 (the beginning of the comparable prior reporting period), and includes pro forma adjustments related to the amortization of acquired intangible assets, direct and incremental transaction costs reflected in the historical financial statements. Specifically, the following adjustments were made: • For the year ended December 31, 2021, the Company's direct and incremental transaction costs of $ 5.7 million are excluded from the pro forma condensed combined net loss. 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, 2020. It should not be taken as representative of future results of operations of the combined company.

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 Europe 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. As of December 31, 2019, the Company only had one segment. For the year ended December 31, 2019, our International segment had revenue of approximately $ 0.1 million, a net loss of approximately $ 0.4 million, property and equipment of $ 42,000 , depreciation and amortization of $ 0.1 million, and expenditures for property and equipment of $ 13,000 .

During 2021 and 2020, no impairments were recorded on our property and equipment and tangible and intangible long-lived assets. During 2021, no impairments were recorded on our intangible assets. During 2020, we recognized $ 0.1 million of impairment related to an intangible asset (a tradename) that Xometry ceased using in our U.S. reporting unit and wrote down the tradename to zero , its estimated fair value. The Company’s estimate of fair value considered discounted future cash flows associated with future use of the tradename. The following tables provides a roll forward of the carrying amount of goodwill (in thousands): 2021 2020 Balance as of January 1: Gross goodwill $ 3,907 $ 3,907 Accumulated impairments ( 3,074 ) ( 1,719 ) Net goodwill as of January 1, 833 2,188 Goodwill acquired during the year 253,839 — Impact of foreign exchange — 154 Impairment expense — ( 1,509 ) Net goodwill as of December 31, $ 254,672 $ 833 During 2020 our goodwill impairment analysis indicated that a certain reporting unit with goodwill attributed to it had a carrying amount which exceeded its fair value. The underperformance of the reporting unit relative to its expected performance drove the decline in the fair value of the reporting unit. As a result, during the year ended December 31, 2020, Xometry recorded a pretax charge to reduce the carrying value of goodwill by $ 1.5 million. As of December 31, 2021 and 2020, Xometry’s goodwill of $ 254.7 million is part of Xometry’s U.S. operating segment. Aggregate amortization expense for amortizing intangibles assets was $ 0.5 million and $ 0.8 million for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, estimated amortization expense for the next five years is: $ 3.4 million in 2022, $ 3.3 million in 2023, $ 3.2 million in 2024, $ 3.2 million in 2025, and $ 3.2 million in 2026.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	(a) Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of Xometry and its subsidiaries. All intercompany transactions and balances have been eliminated. The accompanying consolidated financial statements and related disclosures are presented in accordance with U.S. generally accepted accounting principles ("GAAP"). 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 since December 9, 2021. 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 consolidated entity as noncontrolling interest and classify their interest as a component of total equity, separate from total stockholders’ equity (deficit) on our Consolidated Balance Sheets. We include net income (loss) attributable to the noncontrolling interests in net income (loss) in our Consolidated Statements of Operations and Comprehensive Loss.
Reclassifications	(b) Reclassifications Certain line items on the Company’s consolidated financial statements have been reclassified to conform to the current period presentation. These reclassifications have not changed the results of operations of prior periods.
Use of Estimates	(c) Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with 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 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	(d) 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 consolidated statements of operations. Acquisition costs, such as legal and consulting fees, are expensed as incurred.
Fair Value Measurements and Financial Instruments	(e) 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.
Cash and Cash Equivalents	(f) Cash and Cash Equivalents Cash and cash equivalents consist of cash held in checking accounts and investments in money market funds. The Company considers all highly liquid securities purchased with an initial maturity of three months or less to be cash equivalents. These investments are stated at cost, which approximates fair value.
Marketable Securities	(g) 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 the short term bond fund. We consider our marketable securities as available for use in current operations, and therefore classify these securities as current assets on the Consolidated Balance Sheets. As of December 31, 2021, the Company's marketable securities of $ 30.5 million 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 period from August 2021 through December 31, 2021, the Company recorded an unrealized loss of $ 2.0 million related to these securities which is recorded in other expenses on the Consolidated Statements of Operations and Comprehensive Loss.
Accounts Receivable	(h) Accounts Receivable Accounts receivable are stated at the amount the Company expects to collect from outstanding balances. For customers for which Xometry provides credit, the Company performs credit inquiries, including references checks, and query 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.
Inventory	(i) Inventory Inventory consists primarily of work-in-progress, raw materials and tools. Inventory is stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out (“FIFO”) method. The Company periodically reviews its inventory for slow-moving, damaged and discontinued items and provides allowances to reduce such items identified to their recoverable amounts, if needed.
Property and Equipment and Long-Lived Assets	(j) 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 year s, 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 $ 5.2 million and $ 3.6 million for the years ended December 31, 2021 and 2020, respectively. 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.
Investment In Unconsolidated Joint Venture	(k) Investment In Unconsolidated Joint Venture We account for our investment in unconsolidated joint venture using the equity method of accounting as we exercise significant influence, but do not control the entity. Under the equity method of accounting, the net equity investments of the Company are reflected in the accompanying Consolidated Balance Sheets and the Company’s share of net income from the joint venture is included in the accompanying Consolidated Statements of Operations and Comprehensive Loss. On a periodic basis, management assesses whether there are any indicators that the value of the Company’s investment in the unconsolidated joint venture may be other-than-temporarily-impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such a decline in value is deemed to be other than-temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. Evidence of a loss in value might include, but would not necessarily be limited to, absence of an ability to recover the carrying amount of the investment or inability of the investee to sustain an earnings capacity that would justify the carrying amount of the investment. This evaluation consists of several qualitative and quantitative factors including recent financial results and operating trends of the investee and available information that may affect the value of our investment. No impairment loss on our investment in unconsolidated joint venture was recognized during the year ended December 31, 2021.
Revenue	(l) Revenue The Company derives substantially all of its revenue in the U.S. and Europe from the sale of parts and assemblies fulfilled using a vast network of manufacturers. The Company recognizes revenue from the sales to its buyers 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 customers. 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 customer 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 sellers 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 seller and (iv) Xometry bears certain risk for product quality to the extent the buyer is not satisfied with the final product. In connection with the acquisition of Thomas on December 9, 2021, our revenue also includes the sale of internet 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. A purchase order with a customer may involve multiple performance obligations, including a combination of some or all of the 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 is transferred to the customer. Revenue is shown net of estimated returns, refunds, and allowances. At December 31, 2021, the Company has a $ 0.2 million provision for estimated returns, refunds or allowances. At December 31, 2020, the Company has a $ 0.1 million 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 derived from payments received 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 (in thousands): Contract liabilities at December 31, 2019 $ 1,821 Revenue recognized ( 67,450 ) Payments received in advance 67,984 Contract liabilities at December 31, 2020 $ 2,355 Acquired contract liabilities 6,634 Revenue recognized ( 126,997 ) Payments received in advance 125,871 Contract liabilities at December 31, 2021 $ 7,863 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 customer 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 Consolidated Statements of Operations and Comprehensive Loss. For the period from December 9, 2021 through December 31, 2021, we recognized approximately $ 0.5 million of amortization related to deferred sales commissions.
Cost of Revenue	(m) Cost of Revenue Cost of revenue primarily consists of the cost of the products that are manufactured or produced by the Company’s sellers for delivery to buyers on the Company's platforms, internal and external production costs, shipping costs, and certain internal depreciation.
Leases	(n) 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 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 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 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	(o) 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 years ended December 31, 2021 and 2020, the Company’s advertising costs were $ 20.7 million and $ 12.0 million, respectively.
Operations and Support	(p) Operations and Support Operations and support expenses are the costs the Company incurs in support of the customers and sellers on Xometry’s platforms which are provided by phone, email and chat for purposes of resolving customer and seller 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 customer and seller service.
Product Development	(q) 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	(r) 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	(s) 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 issues 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 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 Attributable to Common Stockholders	(t) Net Loss Per Share Attributable to Common Stockholders 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 year. The diluted net loss per share is computed by giving effect to all potentially dilutive securities outstanding for the year. For the years 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 year to be allocated between common stock and participating securities based upon their respective rights to receive dividends as if all income for the year 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 share proportionately in the Company’s net losses.
Income Taxes	(u) Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. To the extent that it is not considered to be more likely than not that a deferred tax asset will be realized, a valuation allowance is established. The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained and are measured at the largest amount that is greater than 50% likely of being realized. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. Changes in recognition or measurement are reflected in the year in which the change in judgment occurs.
Commitments and Contingencies	(v) Commitments and Contingencies Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.
Intangible Assets	(w) Intangible Assets Intangible assets are carried at cost and amortized on a straight-line basis over their estimated useful lives, which range from one to 15 years . Xometry reviews definite-lived intangible assets for impairment under the long-lived asset model described in Property and Equipment and Long-Lived Assets above.
Goodwill	(x) Goodwill Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is not amortized. The Company test goodwill for impairment annually in the fourth quarter, or more frequently, if needed, and when there is a triggering event (e.g., a deterioration in general economic conditions or in the environment in which Xometry operates). When impairment indicators are identified the Company compares each reporting unit’s fair value to its carrying amount, including goodwill. An impairment loss is recognized as the difference, if any, between each reporting unit’s carrying amount and its fair value to the extent the difference does not exceed the total amount of goodwill allocated to the reporting unit. Xometry determines the fair value of each reporting unit using an income approach. Under the income approach, the Company based fair value on estimated discounted future cash flows of each reporting unit. Determining the fair value of each reporting unit is judgmental in nature and requires the use of significant estimates and assumptions, including revenue growth rates and EBITDA margins, discount rates and future market conditions, among others (Level 3).
Recently Issued Accounting Standards	(y) Recently Issued Accounting Standards New Accounting Pronouncements Effective in the Year Ended December 31, 2021 In October 2021, the FASB issued a new accounting standard on the topic of business combinations, accounting for contract assets and contract liabilities from contracts with customers, Accounting Standard Update ("ASU") 2021-08, Business Combinations (Topic 805). The amendment in this update improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency. This update requires entities to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606. The guidance is effective for interim and annual periods beginning after December 15, 2022 with early adoption permitted. The Company adopted ASU 2021-08 on November 1, 2021 . In connection with the Company's business combinations during the fourth quarter of 2021, the Company recognized its acquired contract asset and liabilities in accordance with ASC 606. 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.
