Accounting Policies [Abstract]

Summary of Significant Accounting Policies

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and include the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Significant estimates and assumptions made in the accompanying consolidated financial statements may include, but are not limited to, valuation of intangible asset, contingent consideration liability, collectability of receivables, recoverability of long-lived assets, valuation of inventory, operating lease right-of-use (“ROU”) assets and liabilities, other investments, fair value of stock options, recoverability of net deferred tax assets and related valuation allowance, and certain accruals. Estimates are based on historical experience and on various assumptions that the Company believes are reasonable under current circumstances. Actual results could differ materially from those estimates. Management periodically evaluates such estimates and assumptions, and they are adjusted prospectively based upon such periodic evaluation.

Cash, Cash Equivalents and Restricted Cash

The Company considers cash on hand, cash in demand deposit accounts including money market funds, and instruments with a maturity date of 90 days or less at date of purchase to be cash and cash equivalents. The Company maintains its cash and cash equivalent balances with banks. At times, the cash and cash equivalent balances may exceed federally insured limits. The Company does not believe that this results in any significant credit risk as the Company’s policy is to place its cash and cash equivalents in highly-rated financial institutions. The Company defines restricted cash as cash that is legally restricted as to withdrawal or usage. The Company’s restricted cash primarily relates to an amount in escrow related to a manufacturing contract with a supplier.

Investments in Debt and Equity Securities

Investments in debt securities have been classified as available-for-sale and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. The Company determines the appropriate classification of its investments in available-for-sale debt securities at the time of purchase. The Company considers all marketable securities available-for-sale, including those with maturity dates beyond 12 months, and therefore classifies these securities within current assets on the consolidated balance sheets, as applicable, as they are available to support current operational liquidity needs.

Unrealized gains and losses are excluded from earnings and reported as a component of comprehensive income (loss). The Company periodically evaluates whether declines in fair values of its marketable securities below their book value are other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company’s ability and intent to hold the marketable security until a forecasted recovery occurs. Additionally, the Company assesses whether it has plans to sell the security or it is more likely than not that it will be required to sell any marketable securities before recovery of its amortized cost basis. Realized gains and losses and declines in fair value judged to be other than temporary, if any, on marketable securities are included in other income (expenses), net on the consolidated statements of operations and comprehensive income (loss). The cost of investments sold is based on the specific-identification method. Interest on marketable securities is included in interest income.

The Company has strategic investments in certain privately held companies, with no readily determinable fair value. The Company elected the measurement alternative under which it measures these investments at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investments. The Company will monitor the information that becomes available from time to time and adjust the carrying values of these investments if there are identified events or changes in circumstances that have a significant adverse effect on the fair values or if there are observable changes in fair value. Impairment loss, which is generally the difference between the carrying value and the fair value of the investment, is recorded in other income (expense) in the consolidated statements of operations and comprehensive income (loss). As of December 31, 2023 and 2022, total other investments of $1.5 million and $8.3 million, respectively, were included in deposits and other assets in the consolidated balance sheets. As a result of the LimFlow acquisition, the Company recognized a gain on the pre-existing investment in LimFlow of $3.5 million. which was recorded in other income (expense) in consolidated statements of operations and comprehensive income (loss). See N ote 3. Business Combination for additional information. Additionally, during the year ended December 31, 2023, the Company recorded an impairment loss of $0.6 million in other income (expense) in the consolidated statements of operations and comprehensive income (loss) related to a strategic investment. There were no impairment losses recorded during the years ended December 31, 2022 or 2021.

Accounts Receivable, net

Trade accounts receivable are recorded at the invoiced amount, net of any allowance for credit losses. The Company evaluates the expected credit losses of accounts receivable, considering historical credit losses, current customer-specific information and other relevant factors when determining the allowance. An increase to the allowance for credit losses results in a corresponding increase in selling, general and administrative expenses (“SG&A”). The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. The allowance for credit losses was $1.3 million and $0.8 million as of December 31, 2023 and 2022, respectively.

Inventories, net

The Company values inventory at the lower of the actual cost to purchase or manufacture the inventory or net realizable value for such inventory. Cost, which includes material, labor and overhead costs, is determined on the first-in, first out method, or FIFO. The Company regularly reviews inventory quantities in process and on hand, and when appropriate, records a provision for obsolete and excess inventory. The Company writes down inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected requirements based on future demand and as compared to remaining shelf life. The estimate of excess quantities is subjective and primarily dependent on the Company’s estimates of future demand for a particular product. If the estimate of future demand is inaccurate based on actual sales, the Company may increase the write down for excess inventory for that component and record a charge to inventory impairment in cost of goods sold on the accompanying consolidated statements of operations and comprehensive income (loss).

Property and Equipment, net

Property and equipment are stated at cost. Additions and improvements that extend the lives of the assets are capitalized while expenditures for repairs and maintenance are expensed as incurred. Depreciation is provided using the straight-line method over the estimated useful lives of the assets, ranging from two to ten years. Leasehold improvements are depreciated over the shorter of the useful life of the improvement or the lease term, including renewal periods that are reasonably assured. Upon sale or disposition of property and equipment, any gain or loss is included as operating expense in the accompanying consolidated statements of operations and comprehensive income (loss).

Right-of-use Assets and Lease Liabilities

The Company determines if an arrangement contains a lease at inception and determines the classification of the lease, as either operating or finance, at commencement.

Right-of-use assets and lease liabilities are recorded based on the present value of future lease payments which factors in certain qualifying initial direct costs incurred as well as any lease incentives received. If an implicit rate is not readily determinable, the Company utilizes inputs from third-party lenders to determine the appropriate discount rate. Lease expense for operating lease payments is recognized on a straight-line basis over the lease term. Lease terms may factor in options to extend or terminate the lease.

The Company adheres to the short-term lease recognition exemption for all classes of assets (i.e. facilities and equipment). As a result, leases with an initial term of twelve months or less are not recorded on the balance sheet and are recognized on a straight-line basis over the lease term. In addition, for certain equipment leases, the Company accounts for lease and non-lease components, such as services, as a single lease component as permitted.

Business Combination

Under the acquisition method of accounting, ASC 805, Business Combinations, the Company allocates the fair value of the total consideration transferred to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the date of acquisition. Determining these fair values require the Company to make estimates and assumptions, especially with respect to the intangible asset. The Company records the excess consideration over the aggregate fair value of tangible and intangible assets, net of liabilities assumed, as goodwill. Costs that the Company incurs to complete the business combination, such as legal and other advisory fees, are expensed as they are incurred.

In an acquisition with contingent consideration which can be earned by the sellers upon the completion of certain future performance or other milestones, the acquisition-date fair value of contingent consideration liability is recorded as a component of accrued liabilities and/or other long-term liabilities. These estimates require significant management judgment, including evaluating the probability of achieving certain future milestones. Changes in the fair value of the contingent consideration subsequent to the acquisition date are recognized in SG&A in the consolidated statements of operations and comprehensive income (loss).

If the initial accounting for a business combination is incomplete by the end of a reporting period that falls within the measurement period, the Company reports provisional amounts in its financial statements. During the measurement period, the Company adjusts the provisional amounts recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. The Company records these adjustments to the provisional amounts with a corresponding offset to goodwill. Any adjustments identified after the measurement period are recorded in the consolidated statements of operations and comprehensive income (loss).

Intangible Assets and Goodwill

Assets acquired, including intangible asset, and liabilities assumed are measured at fair value as of the acquisition date. Goodwill, which has an indefinite useful life, represents the excess of cost over fair value of the net assets acquired.

In accordance with ASC 350, Intangibles-Goodwill and Other, the acquired goodwill is not amortized; however, it is reviewed for impairment at least annually during the fourth quarter, or more frequently if an event occurs indicating the potential for impairment. Goodwill is considered to be impaired if the carrying value of the reporting unit exceeds its respective fair value.

The Company performs its goodwill impairment analysis at the reporting unit level, which aligns with the Company’s reporting structure and availability of discrete financial information. During the goodwill impairment review, the Company assesses qualitative factors to determine whether it is more likely than not that the fair values of the Company’s reporting units are less than the carrying amounts, including goodwill. The qualitative factors include, but are not limited to, macroeconomic conditions, industry and market considerations, and the Company’s overall financial performance. If, after assessing the totality of these qualitative factors, the Company determines that it is not more likely than not that the fair values of the Company’s reporting units are less than the carrying amounts, then no additional assessment is deemed necessary. Otherwise, the Company proceeds to compare the estimated fair values of the reporting units with the carrying values, including goodwill. If the carrying amounts of the reporting units exceed the fair values, the Company records an impairment loss based on the difference. The Company may elect to bypass the qualitative assessment in a period and proceed to perform the quantitative goodwill impairment test.

The Company’s identifiable intangible asset with a finite life is comprised of acquired developed technology. The cost of identifiable intangible asset with finite lives is generally amortized on a straight-line basis over the assets’ respective estimated useful life of 15 years.

The Company performs regular reviews to determine if any event has occurred that may indicate that the intangible asset with finite useful lives are potentially impaired. If indicators of impairment exist, an impairment test is performed to assess the recoverability of the affected assets by determining whether the carrying amount of such assets exceeds the undiscounted expected future cash flows. If the affected assets are not recoverable, the Company estimates the fair value of the assets and records an impairment loss if the carrying value of the assets exceeds the fair value. Factors that may indicate potential impairment include a significant decline in the Company’s stock price and market capitalization compared to the net book value, significant changes in the ability of a particular asset to generate positive cash flows for the Company’s strategic business objectives, and the pattern of utilization of a particular asset.

Capitalized Software

The Company capitalizes certain development costs related to internal-use software. Costs associated with preliminary project activities and post-implementation activities are expensed as incurred. Software development costs are capitalized when the technological feasibility has been established and it is probable that the project will be completed, and the software will be used as intended. The Company capitalizes certain costs related to specific upgrades and enhancements when it is probable that such expenditures will result in additional functionality of the software to its customers. In general, such costs primarily include payroll and payroll-related costs for employees directly associated with development and enhancement of the software.

Impairment of Long-lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparing the carrying amount to the future net undiscounted cash flows which the assets are expected to generate. If such assets are considered impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset. The Company has not identified any such impairment losses to date.

Fair Value of Financial Instruments

The Company’s cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to their liquidity or short maturities.

The Company measures and records certain financial assets and liabilities at fair value on a recurring basis. U.S. GAAP provides a fair value hierarchy that distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels.

•Level 1—Adjusted quoted prices in active markets for identical assets or liabilities.

•Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of assets or liabilities.

See Note 4 . Fair Value Measurements for further information.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company sells its products primarily to hospitals in the United States through its direct sales force. The Company recognizes revenue for arrangements where the Company has satisfied its performance obligation of shipping or delivering the product. For sales where the Company’s sales representatives hand-deliver products directly to the hospitals, control of the products transfers to the customers upon such hand delivery. For sales where products are shipped, control of the products transfers either upon shipment or delivery of the products to the customer, depending on the shipping terms and conditions. Revenue from product sales is comprised of product revenue, net of product returns, discounts, administrative fees and sales rebates. The Company has elected to account for shipping and handling activities that occur after the customer has obtained control as a fulfillment activity, and not a separate performance obligation.

Performance Obligation—The Company has revenue arrangements that consist of a single performance obligation, the shipping or delivery of the Company’s products. The satisfaction of this performance obligation occurs with the transfer of control of the Company’s product to its customers, either upon shipment or delivery of the product.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods. The amount of revenue recognized is based on the transaction price, which represents the invoiced amount, net of discounts, administrative fees and sales rebates, where applicable. The Company provides a standard 30-day unconditional right of return period. The Company establishes estimated provisions for returns at the time of sale based on historical experience. Historically, the actual product returns have been immaterial to the Company’s consolidated financial statements.

For both the years ended December 31, 2023 and 2022, the Company recorded $1.2 million of unbilled receivables, which are included in accounts receivable, net, in the accompanying consolidated balance sheets.

The Company disaggregates revenue between Venous Thromboembolism (“VTE”) and Emerging Therapies. Revenue from VTE and Emerging Therapies is as follows:


	Years Ended December 31,
	2023		2022		2021
VTE	$	476,275	$	381,431	$	276,984
Emerging Therapies	17,357		2,040		—
Total Revenue	$	493,632	$	383,471	$	276,984

Revenue from the Company's products by geographic area, based on the location where title transfers, is as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
United States	$	469,864	$	374,040	$	274,402
International	23,768		9,431		2,582
Total revenue	$	493,632	$	383,471	$	276,984

The Company offers payment terms to its customers of less than three months and these terms do not include a significant financing component. The Company excludes taxes assessed by governmental authorities on revenue-producing transactions from the measurement of the transaction price.

The Company offers its standard warranty to all customers. The Company does not sell any warranties on a standalone basis. The Company’s warranty provides that its products are free of material defects and conform to specifications, and includes an offer to repair, replace or refund the purchase price of defective products. This assurance does not constitute a service and is not considered a separate performance obligation. The Company estimates warranty liabilities at the time of revenue recognition and records it as a charge to cost of goods sold.

Costs associated with product sales include commissions and are recorded in SG&A expenses. The Company applies the practical expedient and recognizes commissions as an expense when incurred because the amortization period is less than one year.

Cost of Goods Sold

Cost of goods sold consists primarily of the cost of raw materials, components, direct labor and manufacturing overhead. Overhead costs include the cost of quality assurance, material procurement, inventory control, facilities, equipment and operations supervision and management, including stock-based compensation. Cost of goods sold also includes depreciation expense for production equipment, inventory impairment charges, and certain direct costs such as shipping and handling costs.

Advertising Costs

Advertising costs are charged to operations as incurred. Advertising costs were $1.2 million, $1.0 million and $0.3 million for the years ended December 31, 2023, 2022 and 2021, respectively. Advertising costs are included in SG&A expenses in the accompanying consolidated statements of operations and comprehensive income (loss).

Research and Development

Research and development costs are expensed as incurred and include the costs to design, develop, test, deploy and enhance new and existing products. Research and development costs also include expenses associated with the purchase of intellectual property relating to a particular research and development project that has no alternative future use, clinical studies, registries and sponsored research. These costs include direct salary and employee benefit related costs for research and development personnel, costs for materials used and costs for outside services.

Patent-related Expenditures

Expenditures related to patent research and applications, which are primarily legal fees, are expensed as incurred and are included in SG&A expenses in the accompanying consolidated statements of operations and comprehensive income (loss).

Stock-based Compensation

The Company's stock based compensation arises from restricted stock units (“RSU”), stock options and the Company's Employee Stock Purchase Plan (“ESPP”).

The fair value of RSUs are determined by the closing stock price of the Company’s common stock on the awards’ grant date and the expense is recognized based on the estimated number of awards that are expected to vest. The fair value of the stock options and stock purchased under the ESPP is calculated using the Black-Scholes option pricing model, which requires valuation assumptions of expected term, expected volatility, risk-free interest rate, and expected dividend yield. For the purposes of utilizing the Black-Scholes valuation model for the stock options, the Company uses the simplified method for determining the expected term of the granted options. The simplified method is used since the Company does not have adequate historical data to utilize in calculating the expected term of options.

Stock-based compensation is recognized over the service period. The Company estimates and adjusts forfeiture rates based on a periodic review of recent forfeiture activity. Adjustments in the estimated forfeiture rates could cause changes in the amount of expense that is recognized in future periods.

Income Taxes

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Management assesses the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. As of December 31, 2023, the net deferred tax assets have been partially offset by a valuation allowance. As of December 31, 2022, the net deferred tax assets were fully offset by a valuation allowance.

The Company recognizes uncertain income tax positions at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. The Company’s policy is to recognize interest and penalties related to the underpayment of income taxes as a component of provision for income taxes.

Foreign Currency Translation

When the functional currencies of the Company’s foreign subsidiaries are currencies other than the U.S. dollar, the assets and liabilities of the foreign subsidiaries are translated into U.S. dollars at the exchange rate in effect on the balance sheet date. Income and expense items of the subsidiaries are translated into U.S. dollars at the average exchange rates prevailing during the period. Gains or losses from these translation adjustments are

reported as a separate component of stockholders’ equity in accumulated other comprehensive income (loss) until there is a sale, or complete or substantially complete liquidation of the Company’s investment in the foreign subsidiaries, at which time the gains or losses will be realized and included in consolidated net income (loss). Transaction gains and losses are included in other income (expense) and have not been significant for the years presented.

For the Company's intercompany accounts that are denominated in the functional currency of a foreign subsidiary, gains and losses resulting from the remeasurement of such intercompany transactions that the Company considers to be of a long-term investment nature are recorded in accumulated other comprehensive income (loss) as a separate component of stockholders’ equity. Additionally, gains and losses resulting from the remeasurement of such intercompany transactions from those foreign subsidiaries for which the Company anticipates settlement in the foreseeable future are recorded in the consolidated statements of operations and comprehensive income (loss).

Comprehensive Income (Loss)

The Company’s comprehensive income (loss) is comprised of net income (loss) and changes in unrealized gain and losses on available-for-sale debt securities and gains or losses from foreign currency translation adjustments.

Net Income (Loss) per Share of Common Stock

Basic net income (loss) per share is computed by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period, without consideration for potential dilutive common shares. Diluted net income (loss) per share is computed using the treasury stock method by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock and potentially dilutive securities outstanding for the period. For purposes of the diluted net income (loss) per share calculation, shares from common stock options, RSUs and ESPP are potentially dilutive securities. For the periods the Company is in a net loss position, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential dilutive common shares would have been anti-dilutive.

Segment Reporting

Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company has determined it operates in one segment. Segment information is consistent with how management reviews the business, makes investing and resource allocation decisions and assesses operating performance.

Recently Issued Not Yet Adopted Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting, Topic 280, which requires enhanced disclosures primarily around segment expenses for all public entities, including public entities with a single reportable segment. On an annual and interim basis, entities are required to disclose significant segment expenses that are regularly provided to the CODM. The ASU is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact of the new standard on its consolidated financial statements and related disclosures.

In December 2023, FASB issued ASU 2023-09, Income Tax, Topic 740, which requires public companies to disclose specific categories in the rate reconciliation, disaggregate information related to income taxes paid, income or loss from operations before income tax expense or benefit, and income tax expense or benefit from operations. The ASU is effective for annual fiscal years beginning after December 15, 2024, with early adoption permitted. Amendments are applicable on a prospective basis with retrospective application permitted. The Company is currently evaluating the impact of the new standard on its consolidated financial statements and related disclosures.

Provision for income taxes as a percentage of income (loss) before taxes	138.5		%	(11.8		%)	7.9		%

Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards.

The tax effects of significant items comprising the Company’s deferred taxes are as follows (in thousands):


	December 31,
	2023		2022
Deferred tax assets
Capitalized R&D expenses	$	33,528	$	14,250

ASC 740, Income Taxes requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not”. Realization of the future tax benefits is dependent on the Company's ability to generate sufficient taxable income within the carryforward periods. Based on its evaluation, including projected taxable losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly has provided for a partial valuation allowance in the US and certain foreign jurisdictions. The Company will continue to assess its position on the realizability of its deferred tax assets, until such time as sufficient positive evidence may become available to allow the Company to reach a conclusion that a significant portion of the valuation allowance will no longer be needed. Any release of the valuation allowance will result in a material benefit recognized in the quarter of release. The valuation allowance increased by approximately $23.5 million during the year ended December 31, 2023. Additionally, the Company recorded $0.4 million and nil of deferred tax assets within deposits and other assets in the consolidated balance sheets as of December 31, 2023 and 2022, respectively.

The effective tax rate of the Company’s provision (benefit) for income taxes differs from the federal statutory rate as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
Statutory rate	$	892	$	(5,499)	$	2,244
State taxes, net of federal benefit	(683)		(1,060)		(317)

Total	$	5,882	$	3,082	$	845

For tax years beginning after December 31, 2021, certain research and development expenses are required to be capitalized and amortized over a five year or fifteen year period under the Tax Cuts and Jobs Act, which was signed into law December 22, 2017. The Company has reviewed and incorporated this change which impacts the expected U.S. federal and state tax expense and cash taxes to be paid for the tax years ending December 31, 2022 and December 31, 2023.

As a result of losses incurred in the past, the Company has net operating loss (“NOL”) carry-forwards that are available to offset future taxable income and subject to expiration rules and to Internal Revenue Code of 1986, as amended (“IRC”) §382. In general, IRC §382 may impact the amount of NOLs that can be utilized each year after certain ownership changes occur. An ownership change occurs, generally, if the percentage of stock of the loss corporation owned by one or more 5% shareholders has increased by more than 50 percentage points relative to the lowest percentage of stock of the loss corporation owned by the same 5% shareholders at any time during the testing period (generally, the three-year period preceding a testing date).

Net operating losses and tax credit carryforwards as of December 31, 2023 are as follows (in thousands):


	Amount		Expiration Years
Net operating losses, federal - expiring	$	7,997	2036-2037
Net operating losses, federal - indefinite	$	1,774	Indefinite
Net operating losses, state - expiring	$	25,484	2032-2043
Net operating losses, state - indefinite	$	1,625	Indefinite
Net operating losses, foreign - expiring	$	47,233	2028-2030
Net operating losses, foreign - indefinite	$	5,041	Indefinite
Tax credits, federal	$	9,781	2031-2043
Tax credits, state	$	13,346	Indefinite

Pursuant to an IRC §382 limitation analysis performed by the Company, it was noted that an ownership change, as defined under IRC §382, occurred on March 29, 2018 and December 31, 2021. Usage of NOL’s generated prior to March 29, 2018 will be limited to $3.0 million for calendar years 2019 through 2022, $0.7 million for 2023, $0.6 million from 2024 through 2039, and $0.2 million for 2040 for both federal and state purposes. The IRC §382 ownership change that occurred on December 31, 2021 did not further limit the use of the Company's NOL's generated prior to December 31, 2021. Of the federal net operating loss and the state net operating loss carryforward amounts, $9.8 million and $19.5 million are subject to the IRC §382 limitation, respectively.

In the ordinary course of its business the Company incurs costs that, for tax purposes, are determined to be qualified research expenditures within the meaning of IRC §41 and are, therefore, eligible for the Increasing Research Activities credit under IRC §41. Research & Development credit carryovers generated prior to March 29, 2018 are limited under IRC §383 to $0.3 million a year for both federal and state purposes. Additionally, R&D credit carryovers acquired as part of the LimFlow acquisition are limited under IRC §383 for all credits generated prior to November 15, 2023. The limitation is expected to be immaterial. The Company has adjusted the deferred tax assets related to Federal R&D credit carryover to account for any tax credits that will expire unused due to the IRC §383 limitations.

As of December 31, 2023 and 2022, the Company has total uncertain tax positions of $10.6 million and $5.5 million respectively. The Company estimates that these liabilities would be reduced by $10.6 million and $5.5 million, respectively, from offsetting tax benefits associated with the correlative effects of net operating losses and other timing adjustments. The net amounts of all years, if not required, would favorably affect the Company's effective tax rate. No interest or penalties have been recorded related to the uncertain tax positions. A reconciliation of the beginning and ending balances of unrecognized tax benefits is as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
Balance at the beginning of the year	$	5,526	$	2,679	$	882
Additions based on tax positions related to the current year	4,254		2,348		1,352
Additions based on tax positions related to prior years	803		499		445
Deductions based on tax positions related to prior years	—		—		—
Balance at the end of the year	$	10,583	$	5,526	$	2,679

It is not expected that there will be a significant change in uncertain tax position in the next 12 months. The Company is subject to U.S. federal and state income tax in multiple state jurisdictions, and various foreign jurisdictions. In the normal course of business, the Company is subject to examination by tax authorities. As of the date of the financial statements, there are no income tax examinations in progress. The statute of limitations for tax years ended December 31, 2020, December 31, 2019, and December 31, 2020, are open for federal, state, and foreign tax purposes, respectively.

COMMITMENTS AND CONTINGENCIES

Operating Leases

The Company has operating leases for facilities and certain equipment. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. Lease expense for operating leases is recognized on a straight-line basis over the lease term. For lease agreements, other than long-term real estate leases, the Company combines lease and non-lease components (see Note 2. Summary of Significant Accounting Policies). The variable lease payments primarily relate to common area maintenance, property taxes, and insurance. The operating leases for facilities expire at various dates through July 2041 and some contain renewal options, the longest of which is for five years. The ROU asset and lease liability includes renewal options if the Company is reasonably certain to exercise such renewal options.

The interest rate implicit in lease agreements is typically not readily determinable, and as such the Company used the incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The incremental borrowing rate is defined as the interest rate the Company would incur to borrow on a collateralized basis, considering factors such as length of lease term. The following table presents the weighted average remaining lease term and discount rate:


	Years Ended December 31,
	2023		2022		2021
Weighted average remaining term	17.8 years		17.1 years		19.2 years
Weighted average discount rate	6.1	%	6.1	%	6.0	%

Cash paid for amounts included in the measurement of operating leases were as follows (in thousands):


	Years Ended December 31,
	2023		2022		2021
Cash paid for amounts included in the measurement of operating lease liabilities	$	3,445	$	2,700	$	14,600

Total lease costs were as follows (in thousands):


	Years Ended December 31,

Variable lease cost	723		622		473
Total lease costs	$	5,756	$	5,138	$	2,241

Future minimum lease payments under operating leases liabilities as of December 31, 2023 are as follows (in thousands):


Year ending December 31:	Amount
2024	$	3,560
2025	3,046

The Company signed a ten-year lease for real estate in October 2023, with total undiscounted contractual payments of the lease of $7.2 million, which are expected to commence in October 2024.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and may provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future but have not yet been made. To date, the Company has not been subject to any claims or required to defend any action related to its indemnification obligations.

The Company’s amended and restated certificate of incorporation contains provisions limiting the liability of directors, and its amended and restated bylaws provide that the Company will indemnify each of its directors to the fullest extent permitted under Delaware law. The Company’s amended and restated certificate of incorporation and amended and restated bylaws also provide its board of directors with discretion to indemnify its officers and employees when determined appropriate by the board. In addition, the Company has entered and expects to continue to enter into agreements to indemnify its directors and executive officers.

Legal Proceedings

In December 2023, the Company received a civil investigative demand (“CID”) from the U.S. Department of Justice, Civil Division, in connection with an investigation under the federal Anti-Kickback Statute and Civil False Claims Act (the “Investigation”). The CID requests information and documents primarily relating to meals and consulting service payments provided to health care professionals (“HCPs”). The Company is cooperating with the Investigation. The Company is unable to express a view at this time regarding the likely duration, or ultimate outcome, of the Investigation or estimate the possibility of, or amount or range of, any possible financial impact. Depending on the outcome of the Investigation, there may be a material impact on the Company’s business, results of operations, or financial condition. For more information, please refer to “Item 3. Legal Proceedings” in this Annual Report on Form 10-K.

Licensed Technology

In December 2021, the Company entered into an exclusive, perpetual, royalty free, technology license agreement (the “Licensed Technology”) for use in a particular research and development project that requires total payments of approximately $4.2 million payable in three installments due in 2022 and 2023. The Company accounted for the license as a research and development expense as it was determined not to have an alternative future use. As of December 31, 2023, there was no outstanding balance as the Company satisfied its last installment payment during the year ended December 31, 2023. As of December 31, 2022, the outstanding balance was approximately $1.3 million which was included in accrued expenses and other current liabilities on the consolidated balance sheets.

Sublicense Agreement

In August 2019, the Company entered into a sublicense agreement with Inceptus Medical, LLC (“Inceptus”), pursuant to which Inceptus granted to the Company a non-transferable, worldwide, exclusive sublicense to its licensed intellectual property rights related to the tubular braiding for the non-surgical removal of clots and treatment of embolism and thrombosis in human vasculature other than carotid arteries, coronary vasculature and cerebral vasculature.

Under the sublicense agreement, the Company is required to pay an ongoing quarterly administration fee, which amounted to $87,750, $116,000, and $116,000 for the years ended December 31, 2023, 2022 and 2021, respectively. Additionally, the Company is obligated to pay an ongoing royalty ranging from 1% to 1.5% of the net sales of products utilizing the licensed intellectual property, subject to a minimum royalty quarterly fee of $1,500. In June 2023, the sublicense agreement was terminated and the Company is no longer required to pay any ongoing administration and royalty fees beginning in July 2023.

The Company recorded royalty expense to cost of goods sold of $5,000, $215,000, and $769,000 for the years ended December 31, 2023, 2022, and 2021, respectively.

Self-Insured Health Plan

As of January 1, 2023, the Company implemented a self-insurance program to cover employees and their dependent health benefits, including medical, dental, and vision. As part of the program, the Company also has stop-loss coverage from a third party which limits exposure to large claims. The Company records a liability associated with these benefits that includes an estimate of both claims filed and losses incurred but not yet reported based on historical claims experience. In estimating this accrual, the Company utilizes an independent third-party broker to estimate a range of expected losses, which are based on analyses of historical data. The assumptions are closely monitored and adjusted when necessary by changing circumstances. If the liability generated from incurred claims exceeds the expense recorded, the Company may record an additional expense. As of December 31, 2023, the Company's self-insurance liability, inclusive of administrative fees, was $1.4 million, which is included in accrued expenses and other current liabilities on the consolidated balance sheets.

Equity Incentive Plans

14. EQUITY INCENTIVE PLANS

In 2011, the Company adopted the 2011 Equity Incentive Plan (the “2011 Plan”) to permit the grant of share-based awards, such as stock grants and incentives and non-qualified stock options to employees and directors. The Board has the authority to determine to whom awards will be granted, the number of shares, the term and the exercise price.

In March 2020, the Company adopted the 2020 Incentive Award Plan (the “2020 Plan”), which became effective in connection with the Company's initial public offering in May 2020 (“IPO”). As a result, the Company may not grant any additional awards under the 2011 Plan. The 2011 Plan will continue to govern outstanding equity awards granted thereunder. The Company has initially reserved 3,468,048 shares of common stock for the issuance of a variety of awards under the 2020 Plan, including stock options, stock appreciation rights, awards of restricted stock and awards of restricted stock units. In addition, the number of shares of common stock reserved for issuance under the 2020 Plan will automatically increase on the first day of January for a period of up to ten years, commencing on January 1, 2021, in an amount equal to 3% of the total number of shares of the Company’s capital stock outstanding on the last day of the preceding year, or a lesser number of shares determined by the Company’s board of directors. As of December 31, 2023, there were 6,476,157 shares available for issuance under the 2020 Plan, including 1,620,650 additional shares reserved effective January 1, 2023.

2011 Equity Incentive Plan

Restricted Stock Units

In March 2019, the Company granted, under the 2011 Plan, restricted stock unit awards (“RSUs”) to certain employees that vest only upon the satisfaction of both a time-based service condition and a performance-based condition that was satisfied on the effective date of the IPO of the Company's common stock. The RSUs were subject to four-year cliff vesting and vested in full in March 2023. The vesting was also subject to a market-based condition related to the value of the Company's common stock as of the vesting date. As a result of exceeding the value of the Company's common stock as set forth in the grant agreement, the maximum amount of RSUs were earned and vested during the year ended December 31, 2023.

RSU activity under the 2011 Plan is set forth below:


	Number of Awards	Weighted Average Fair Value
Outstanding, December 31, 2022	2,712,674	$	0.17
Vested	(2,712,674)	(a)
Outstanding, December 31, 2023	—	$	—

_____________

The total fair value of RSUs vested under the 2011 Plan was $170.6 million for the year ended December 31, 2023. No RSUs had vested under the 2011 Plan for the year ended December 31, 2022.

Stock Options

A summary of stock option activities under the 2011 Plan is as follows (intrinsic value in thousands):


	Number of Awards	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Intrinsic Value
Outstanding, December 31, 2020	3,436,785	$	1.36	8.05	$	295,331

Vested and expected to vest at December 31, 2023	937,692	$	2.24	5.20	$	58,777

The aggregate intrinsic values of options outstanding, vested and exercisable, and vested and expected to vest were calculated as the difference between the exercise price of the options and the estimated fair value of the Company’s common stock.

2020 Incentive Award Plan

Restricted Stock Units

RSUs are share awards that entitle the holder to receive freely tradable shares of the Company’s common stock upon vesting. The RSUs cannot be transferred and the awards are subject to forfeiture if the holder’s employment terminates prior to the release of the vesting restrictions. The RSUs generally vest over a four-year period with straight-line vesting and a 25% one-year cliff or over a three-year period in equal amounts on a quarterly basis, provided the employee remains continuously employed with the Company. The fair value of the RSUs is equal to the closing price of the Company’s common stock on the grant date.

RSU activities under the 2020 Plan is set forth below:


	Number of Awards	Weighted Average Fair Value
Outstanding, December 31, 2020	222,564	$	58.86
Granted	515,880	98.98
Vested	(99,758)	78.15
Cancelled	(27,481)	86.41
Outstanding, December 31, 2021	611,205	88.34
Granted	696,111	73.22
Vested	(257,198)	84.15
Cancelled	(50,903)	82.92
Outstanding, December 31, 2022	999,215	79.16
Granted	892,939	59.12
Vested	(458,632)	73.85
Cancelled	(125,524)	73.24
Outstanding, December 31, 2023	1,307,998	$	67.91

In 2021, the Company accelerated the vesting of 8,947 RSUs for a director and accounted for the vesting acceleration as a modification under ASC 718. The Company recognized a one-time stock-based compensation expense as a result of this modification of approximately $0.4 million, which was determined based on the fair value of the Company’s shares of common stock at the time of the modification and was included in SG&A expenses on the consolidated statements of operations and comprehensive income (loss).

The total fair value of RSUs vested under the 2020 Plan during the years ended December 31, 2023, 2022 and 2021, was $28.5 million, $20.2 million and $17.7 million, respectively.

Stock Options

During the year ended December 31, 2023, the Company granted non-qualified stock options to certain employees with vesting over a four-year period on a quarterly basis. The fair value of options granted was calculated using the following weighted average assumptions:



			Year ended December 31, 2023
Expected term (in years)			4.56
Expected volatility			50.35%
Expected dividends			0.00%
Risk free interest rate			4.05%
Weighted-average fair value of options granted			$25.98 per share

Expected term. Due to lack of the Company’s historical share option exercise information, the expected term for options granted was determined using the simplified method. The Company calculated the expected term as the average of the vesting period and the contractual term of the option as the Company believes this represents the best estimate of the expected terms of the stock options.

Expected volatility. Due to lack of the Company’s historical stock price volatility data, the Company used the historical daily changes in the market price of its comparable companies to determine the expected volatility during the equivalent period of the expected term of the stock options.

Expected dividends. The Company has not declared or paid any dividends.

Risk-free interest rates. The Company applies the risk-free interest rate based on the U.S. Treasury yield for the expected term of the option.

The Company uses its historical rate of cancelled or expired unvested shares since inception of the plan as the expected forfeiture rate.

A summary of stock option activities under the 2020 Plan for the year ended December 31, 2023 is as follows (intrinsic value in thousands):


	Number of Awards	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)	Intrinsic Value
Outstanding, December 31, 2022	—	$	—	—	$	—
Granted	181,870	$	56.00
Exercised	(2,720)	$	56.00		$	21
Cancelled	(12,947)	$	56.00
Outstanding, December 31, 2023	166,203	$	56.00	6.10	$	1,483
Vested and exercisable at December 31, 2023	30,348	$	56.00	6.00	$	271
Vested and expected to vest at December 31, 2023	155,278	$	56.00	6.10	$	1,385

Employee Stock Purchase Plan

In May 2020, the Company adopted the 2020 Employee Stock Purchase Plan (“ESPP”), which became effective on the date the ESPP was adopted by the Company’s board of directors. Each offering to the employees to purchase stock under the ESPP will begin on each August 1 and February 1 and will end on the following January 31 and July 31, respectively. The first offering period began on August 1, 2020. On each purchase date, which falls on the last date of each offering period, ESPP participants will purchase shares of common stock at a price per share equal to 85% of the lesser of (1) the fair market value per share of the common stock on the offering date or (2) the fair market value of the common stock on the purchase date. The occurrence and duration of offering periods under the ESPP are subject to the determinations of the Company’s Compensation Committee, in its sole discretion.

The fair value of the ESPP shares is estimated using the Black-Scholes option pricing model with the following assumptions:


	Years Ended December 31,
	2023	2022	2021
Expected term (in years)	0.5	0.5	0.5
Expected volatility	42.08% - 49.89%	56.09% - 72.78%	51.47% - 51.91%
Dividend yield	0.00%	0.00%	0.00%
Risk free interest rate	4.79% - 5.54%	0.48% - 2.96%	0.06% - 0.08%

Total shares of common stock purchased under the ESPP for the years as of December 31, 2023, 2022, and 2021 were 204,545, 133,515 and 85,049, respectively. As of December 31, 2023 and 2022, there were 2,103,629 and 1,767,957 shares, respectively, reserved for future purchases.

Credit Facility

Debt Disclosure [Abstract]

Credit Facility

CREDIT FACILITY

Bank of America Credit Facility

On December 16, 2022, the Company amended its senior secured revolving credit facility with Bank of America (the “Previously Amended Credit Agreement”) under which the Company may borrow loans up to a maximum principal amount of $40.0 million and increases the optional accordion to $120.0 million. The Amended Credit Agreement matures on December 16, 2027.

Advances under the Previously Amended Credit Agreement will bear interest at a base rate per annum (“the Base Rate”) plus an applicable margin (‘the Margin”). The Base Rate equals the greater of (i) the Prime Rate, (ii) the Federal funds rate plus 0.50%, or (iii) the Bloomberg Short-Term Bank Yield Index (“the BSBY”) rate based upon an interest period of one month plus 1.00%, in any case has a floor of 0%. The Margin ranges, depending on average daily availability, from 0.50% to 1.00% in the case of Prime Rate and the Federal funds rate loans, and 1.50% to 2.00% in the case of BSBY Rate loans. As a condition to entering into the Previously Amended Credit Agreement, the Company was obligated to pay a nonrefundable fee of $10,000. The Company is also required to pay an unused line fee at an annual rate of 0.25% per annum of the average daily unused portion of the aggregate revolving credit commitments under the Previously Amended Credit Agreement.

The Previously Amended Credit Agreement also includes the LC Facility of up to $5.0 million. In February 2023, the Company amended the LC Facility to increase the limit to up to $10.0 million. The Company is required to pay the following fees under the LC Facility are as follows: (a) a fee equal to the applicable margin in effect for BSBY loans (currently 2.25%) times the average daily stated amount of outstanding letter of credits; (b) a fronting fee equal to 0.125% per annum on the stated amount of each letter of credit outstanding.

On November 1, 2023, the Company further amended its credit facility (the “Amended Credit Agreement”) to, among other things, increase the amount available for borrowing to up to a maximum principal amount of $75.0 million. Additionally, advances under the amended credit agreement will bear interest at the Base Rate or the BSBY rate, plus the Margin. The Margin ranges from 0.60% to 1.10% in the case of the Base Rate loans and 1.60% to 2.10% in the case of the BSBY rate loans depending on average daily availability, in each case with a floor of 0%. As a condition of entering into the amended credit agreement, the Company was obligated to pay a nonrefundable fee of $88,000. Lastly, the Company amended the LC Facility to increase the limit up to $18.8 million. This amendment was accounted for as a debt modification in accordance ASC 470, Debt.

The Amended Credit Agreement contains certain customary covenants subject to certain exceptions, including, among others, the following: a fixed charge coverage ratio covenant, and limitations of indebtedness, liens, investments, asset sales, mergers, consolidations, liquidations, dispositions, restricted payments, transactions with affiliates and prepayments of certain debt. The Amended Credit Agreement also contains certain events of default subject to certain customary grace periods, including, among others, payment defaults, breaches of any representation, warranty or covenants, judgment defaults, cross defaults to certain other contracts, bankruptcy and insolvency defaults, material judgment defaults and a change of control default.

As of December 31, 2023, the amount available to borrow under the Amended Credit Agreement is approximately $56.1 million, and the Company had four letters of credit in the aggregated amount of $2.4 million outstanding under the LC Facility and as a result, the Company had $16.4 million of unused line of credit. The aggregate stated amount outstanding of letter of credits reduces the total borrowing base available under the Amended Credit Agreement.

As of December 31, 2023, there was no principal amount outstanding, and no cash was pledged under the Amended Credit Agreement, and the Company was in compliance with its covenant requirement. Obligations under the Amended Credit Agreement are secured by substantially all of the Company’s assets, excluding intellectual property.

Deferred Financing Costs

As of December 31, 2023 and 2022, costs incurred directly related to debt are presented in other assets and are being amortized over the five-year life of the Credit Agreement on the straight-line basis as follows (in thousands):

Business Combination and Asset Acquisition [Abstract]

BUSINESS COMBINATION

Acquisition of LimFlow S.A.

On November 15, 2023, the Company completed its acquisition of LimFlow, a medical device company focused on limb salvage for patients with CLTI. The acquisition is expected to accelerate access and adoption of LimFlow’s products into U.S. and other regions providing care to patients worldwide suffering from the most severe form of peripheral artery disease – CLTI and who are facing the prospect of amputation. As a result of the acquisition, LimFlow’s stockholders received as consideration (i) cash, and (ii) contingent consideration related to certain commercial and reimbursement milestones. The results of operations of LimFlow have been included in the consolidated financial statements from the date of the acquisition.

Purchase Price

The total purchase price consisted of the following (in thousands):


	As of November 15, 2023
Cash	$	242,001
Fair value of contingent consideration	65,931
Fair value of previously held investment	10,235
Total purchase price	$	318,167

Contingent Consideration

The LimFlow stockholders can achieve up to $165.0 million of additional contingent consideration if certain commercial and reimbursement milestones are achieved, as outlined under the Contingent Payments of the share purchase agreement with LimFlow. Such payments include (i) up to $140.0 million based on net revenue generated from the sale of the LimFlow System for the year 2024 through 2026 and (ii) up to $25.0 million based on the achievement of certain reimbursement milestones related to the LimFlow System.

The acquisition-date fair value of the contingent consideration was measured using a Monte Carlo simulation which represents Level 3 measurements because they are supported by little or no market activity and reflect the Company’s assumptions in measuring fair value. Estimates and assumptions used in the fair value assessment included forecasted revenues for LimFlow, revenue risk premium, revenue volatility, operational leverage ratio, counterparty credit spread, and weighted average cost of capital. The Company has determined that the range of the potential payments on such contingencies is $65.9 million to $165.0 million.

The fair value of the contingent consideration as of the acquisition was $65.9 million recorded within other long-term liabilities. As of December 31, 2023, the Company did not record any changes in fair value of contingent consideration as none of the underlying assumptions significantly changed.

Previously Held Investment

Prior to the acquisition, the Company held an investment in LimFlow, which represented approximately 3.7% of LimFlow's outstanding equity, and was recorded at cost minus impairment. Authoritative guidance on accounting for business combinations requires that an acquirer remeasure its previously held equity investment in the acquiree at its acquisition-date fair value and recognize the resulting gain or loss in earnings. In connection with acquiring the remaining 96.3% equity interest of LimFlow, the Company remeasured its previously held equity investment to its fair value, as of the date of acquisition, based on the fair value of total consideration transferred. Estimates and assumptions used in the remeasurement represent a Level 3 measurement because they are supported by little or no market activity and reflect the Company’s assumptions in measuring the fair value. As a result of the remeasurement, the Company valued its previously held equity investment in LimFlow at $10.2 million and recognized a gain of $3.5 million, included in other income (expense) in the consolidated statements of operations and comprehensive income (loss) during the year ended December 31, 2023.

The transaction costs associated with the acquisition of LimFlow consisted primarily of legal and financial advisory fees of approximately $8.7 million in addition to $1.7 million of severance and integration related costs, which were expensed as incurred as SG&A expense during the year ended December 31, 2023.

Net assets acquired and liabilities assumed

The preliminary fair values of assets acquired and liabilities assumed were (in thousands):


	As of November 15, 2023
Cash and cash equivalents	$	1,582
Accounts receivable	919
Inventories	2,635
Property and equipment	266
Goodwill	207,800
Intangible asset	146,000
Other current and noncurrent assets	2,155
Accounts payable	(2,509)
Deferred tax liability	(36,500)
Other current and noncurrent liabilities	(4,181)
Total net assets acquired	$	318,167

The Company is still finalizing the allocation of the purchase price, therefore, the fair value estimates assigned to intangible asset, goodwill and the related tax impacts of the acquisition, among other items, are subject to change as additional information is received to complete the analysis including final adjustments to net working capital. The Company expects to finalize the valuation as soon as practicable, but no later than one year after the acquisition date.

The preliminary fair value assigned to the intangible asset acquired was as following (in thousands, except for estimated useful life which are in years):


	Fair value		Useful life
Developed technology	$	146,000	15 years

The preliminary fair value assigned to identifiable intangible asset, the developed technology, acquired as part of the LimFlow acquisition, was estimated using the multi-period excess earnings method. Under this method, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. The estimated fair value was developed by discounting future net cash flows to their present value at market-based rates of return. Such assumptions included forecasted revenues, cost of sales and operating expenses, technology obsolescence, and weighted average cost of capital. The useful life of the developed technology for amortization purposes was determined by considering the period of expected cash flows used to measure the fair values of the intangible asset adjusted as appropriate for entity-specific factors including competitive, economic and other factors that may limit the useful life. The developed technology asset will be amortized on a straight-line basis over its estimated useful life.

Unaudited pro forma financial information


	Years Ended December 31,
	2023		2022
Revenue	$	495,247	$	383,737
Net Loss	$	(40,458)	$	(59,372)

The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved had the acquisition been completed at the beginning of the fiscal year 2022. In addition, the unaudited pro forma financial information is not a projection of future results of operations of the combined company nor does it reflect the expected realization of any synergies or cost savings associated with the acquisition. The unaudited pro forma financial information includes adjustments to reflect the elimination of intercompany transactions, incremental amortization of the identifiable intangible assets and elimination of the remeasurement the Company’s previously held investment in LimFlow
