CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements. All statements other than statements of historical facts contained in this Quarterly Report are forward-looking statements. In some cases, you can identify forward-looking statements by terms such as “may,” “will,”, “would”, “should,” “expect,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “contemplate,” “believe,” “estimate,” “predict,” “potential” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. All statements other than statements of historical fact contained in this Quarterly Report, including without limitation statements regarding our business model and strategic plans for our products, technologies and business, including our implementation thereof, the impact on our business, financial condition and results of operation from the ongoing and global COVID-19 pandemic, or any other pandemic, epidemic or outbreak of an infectious disease in the United States or worldwide, the timing of and our ability to obtain and maintain regulatory approvals, our commercialization, marketing and manufacturing capabilities and strategy, our expectations about the commercial success and market acceptance of our products, the sufficiency of our cash, cash equivalents and short-term investments, and the plans and objectives of management for future operations and capital expenditures are forward-looking statements.

The forward-looking statements in this Quarterly Report are only predictions and are based largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements speak only as of the date of this Quarterly Report and are subject to a number of known and unknown risks, uncertainties, and assumptions, including those described under the sections in this Quarterly Report entitled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and elsewhere in this Quarterly Report. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely upon these forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance, or achievements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise. We intend the forward-looking statements contained in this Quarterly Report to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Notes to Unaudited Condensed Consolidated Financial Statements

1. Organization

Description of Business

Inari Medical, Inc. (the “Company”) was incorporated in Delaware in July 2011 and is headquartered in Irvine, California. The Company develops, manufactures, markets and sells devices for the interventional treatment of venous diseases. The Company received initial 510(k) clearance from the U.S. Food and Drug Administration (the “FDA”) in February 2015 for its FlowTriever system, used primarily to treat pulmonary emboli, and in February 2017 for its ClotTriever system, used for the treatment of deep vein thrombosis.

Initial Public Offering

In May 2020, the Company completed an initial public offering (“IPO”) of its common stock. As part of the IPO, the Company issued and sold 9,432,949 shares of its common stock, which included 1,230,384 shares sold pursuant to the exercise of the underwriters’ over-allotment option, at a public offering price of $19.00 per share. The Company received net proceeds of approximately $163.0 million from the IPO, after deducting underwriters’ discounts and commissions of $12.6 million and offering costs of $3.7 million, of which $1.4 million was incurred as of December 31, 2019.  Upon the completion of the IPO, all shares of Series A, B, and C redeemable convertible preferred stock then outstanding were converted into 31,968,570 shares of common stock on a one-to-one basis.

In addition, on the completion of the IPO, all the Company’s outstanding preferred stock warrants were converted into warrants to purchase an aggregate of 256,588 shares of common stock, which resulted in the reclassification of the convertible preferred stock warrant liability to additional paid-in capital.

In connection with the Company’s IPO, in May 2020, the Company’s certificate of incorporation was amended and restated to provide for 300,000,000 authorized shares of common stock with a par value of $0.001 per share and 10,000,000 authorized shares of preferred stock with a par value of $0.001 per share.

Reverse Stock Splits

In March 2020, the Company’s board of directors approved an amendment to the Company’s certificate of incorporation to effect a reverse split of shares of the Company’s common stock and redeemable convertible preferred stock on a 1-for-1.19 basis.

In May 2020, the Company’s board of directors approved an amendment to the Company’s certificate of incorporation to effect a second reverse split of shares of the Company’s common stock and redeemable convertible preferred stock on a 1-for-1.20 basis. All common stock, redeemable convertible preferred stock, warrants, stock options, RSUs and per share information presented in the financial statements have been adjusted to reflect the effect of both reverse stock splits on a retroactive basis for all periods presented. Any fractional shares resulting from the reverse stock splits are rounded down to a whole share.

2. Summary of Significant Accounting Policies

COVID-19 and the Act

The global healthcare system continues to face an unprecedented challenge as a result of the novel coronavirus, or COVID-19, situation and its impact. COVID-19 is having, and may continue to have, an adverse impact on significant aspects of the Company and the business, including the demand for products, business operations, and the ability to research and develop and bring to market new products and services. The business was most acutely affected by a decline in procedural volumes during the first and second quarter of 2020, and the results for the first quarter of 2021 reflect some recovery from these declines the Company experienced in the first quarter of 2020 as a result of COVID-19. However, with cases continuing to resurge in certain areas, and hospitals at capacity in some instances due to non-COVID-19 treatments, to the extent individuals and hospital systems de-prioritize, delay or cancel deferrable medical procedures, the Company’s business, cash flows, financial condition and results of operations may continue to be negatively affected.

COVID-19 has strained hospital systems around the world, resulting in adverse financial impacts to those systems, which has resulted in and may continue to result in reduced expenditures for the Company’s products. Additionally, COVID-19’s impact on our customers may adversely affect the collectability of the Company’s current and future accounts receivable balance.

The Company continues to actively monitor the COVID-19 situation and its impact. In response to the pandemic, in March 2020 in the United States, governmental authorities recommended, and in certain cases required, that elective, specialty and other

procedures and appointments, be suspended or canceled. Similarly, in March 2020, the governor of California, where the Company’s headquarters are located, issued “stay at home” orders limiting non-essential activities, travel and business operations. Such orders or restrictions significantly decreased the number of procedures performed using the Company’s products during March and April 2020 and otherwise negatively impacted operations.

In response to the impact of COVID-19, the Company implemented a variety of measures to help manage through the impact and position it to resume operations quickly and efficiently once these restrictions were lifted. The Company continues to focus its efforts on the health and safety of patients, healthcare providers and employees, while executing its mission of transforming lives of VTE patients. However, the Company expects the COVID-19 pandemic will continue to negatively impact 2021 performance.

The Taxpayer Certainty and Disaster Tax Relief Act of 2020 ("the Act"), was enacted on December 27, 2020. It was a response to continued market volatility and instability resulting from the coronavirus pandemic and includes provisions to support businesses in the form of loans, grants, and tax changes, among other types of relief. The Company has reviewed and incorporated the income tax changes included in the Act, including the deductibility of meals expenses previously not deductible for tax purposes. We do not believe there will be a material effect on the Company’s income tax provision.  The Company currently does not expect to apply for loans or grants expanded by the Act.

Basis of Presentation of Unaudited Interim Condensed Consolidated Financial Statements

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Certain prior year reported amounts have been reclassified to conform with the 2021 presentation.

The interim condensed consolidated balance sheet as of March 31, 2021, the condensed consolidated statements of operations, mezzanine equity and stockholders’ deficit, and cash flows for the three months ended March 31, 2021 and 2020 are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and reflect, in the opinion of management, all adjustments of a normal and recurring nature that are necessary for the fair presentation of the Company’s consolidated financial position as of March 31, 2021 and its consolidated results of operations and cash flows for the three months ended March 31, 2021 and 2020. The financial data and the other financial information disclosed in the notes to the condensed consolidated financial statements related to the three months periods are also unaudited. The condensed consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future annual or interim period. The condensed consolidated balance sheet as of December 31, 2020 included herein was derived from the audited financial statements as of that date. These interim condensed consolidated financial statements should be read in conjunction with our audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Principles of Consolidation

In May 2020, the Company formed Inari Medical International, Inc., a wholly-owned subsidiary incorporated in Delaware. In September 2020, the Company formed Inari Medical Europe, GmbH, a wholly-owned subsidiary of Inari Medical International, Inc. organized in Switzerland. 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 financial statements include, but are not limited to the collectability of receivables, valuation of inventory, the fair value of common stock warrants, the fair value of preferred stock warrant liabilities, the fair value of stock options, recoverability of the Company’s net deferred tax assets, and related valuation allowance and certain accruals. The Company evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates.

JOBS Act Accounting Election

As an emerging growth company under the Jumpstart Our Business Startups Act of 2012 ("the JOBS Act"), the Company is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies. The Company has elected to take advantage of the extended transition period for adopting new or revised accounting standards that have different effective dates for public and private companies until such time as those standards apply to private companies.

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, cash equivalent and restricted cash balances with banks. Under the Dodd-Frank Wall Street Reform and Consumer Protection Act, deposits of up to $250,000 at FDIC-insured institutions are covered by FDIC insurance. At times, deposits may be in excess of the FDIC insurance limit; however, management does not believe the Company is exposed to any significant related credit risk.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same amounts shown in the consolidated statements of cash flows (in thousands):

Restricted cash as of December 31, 2020 consisted of a cash secured letter of credit in the amount of $338,000 representing collateral for the Company’s facility lease and a compensating balance of $50,000 to secure the Company’s corporate purchasing cards. In February 2021, the Company cancelled the $338,000 cash secured letter of credit and replaced it with a new letter of credit under its Bank of America credit facility with no required cash security.  Accordingly, as of March 31, 2021, the Company had no restricted cash.

Short-Term Investments

Short-term investments 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 debt securities at the time of purchase. Available-for-sale securities with original maturities less than 12 months at the date of purchase are considered short-term investments.

Unrealized gains and losses are excluded from earnings and are reported as a component of comprehensive 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 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, net. The cost of investments sold is based on the specific-identification method. Interest on marketable securities is included in interest income.

Accounts Receivable, net

Trade accounts receivable are recorded at the invoiced amount, net of any allowance for doubtful accounts. Any allowance for doubtful accounts, which is included in selling, general and administrative (“SG&A”) expenses, is developed based upon several factors including the customers’ credit quality, historical write-off experience and any known specific issues or disputes which exist as of the balance sheet date. Account receivable balances are written off against the allowance after appropriate collection efforts are exhausted. The allowance for doubtful accounts was $201,000 and $62,000 as of March 31, 2021 and December 31, 2020, respectively, and no accounts receivable write offs were recognized during the three months ended March 31, 2021 and 2020. Despite the Company’s efforts to minimize credit risk exposure, customers could be adversely affected if future economic and industry trends, including those related to COVID-19, change in such a manner as to negatively impact their cash flows. The full effects of COVID-19 on the Company’s customers are highly uncertain and cannot be predicted. As a result, the Company’s future collection experience can differ significantly from historical collection trends. If the Company’s clients experience a negative impact on their cash flows, it could have a material adverse effect on the Company’s results of operations and financial condition.

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

7

Inari Medical, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

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 the accompanying condensed consolidated statement of operations and comprehensive income (loss).

Property and Equipment

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 three to seven 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 in the accompanying statement of operations.

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, cash equivalents and restricted cash, 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.

See Note 3 for further information.

Convertible Preferred Stock Warrant Liability

The Company accounted for its freestanding warrants to purchase shares of the Company’s convertible preferred stock as liabilities at fair value upon issuance primarily because the preferred shares underlying the warrants contained contingent redemption features outside the control of the Company. The warrants were subject to remeasurement at each balance sheet date and any change in fair value was recognized as the change in fair value of warrant liability and recorded to other expense in the consolidated statements of operations and other comprehensive income (loss). The carrying value of the warrants continued to be adjusted until the completion of the IPO, which occurred in May 2020. At that time, the preferred stock warrant liability was adjusted to fair value and reclassified to additional paid-in capital, a component of stockholders’ equity (deficit) (see Note 3).

Revenue Recognition

The Company recognize revenue in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customer. 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.

Product sales of the FlowTriever and ClotTriever systems are made to hospitals primarily in the United States utilizing the Company’s direct sales force. Revenue is comprised of product revenue net of returns, administration fees and sales rebates.

Performance Obligation—The Company has revenue arrangements that consist of a single performance obligation, 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 that is recognized is based on the transaction price, which represents the invoiced amount and includes estimates of variable consideration such as rebate and administrative fees, where applicable. The Company provides a 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 financial statements.

Assuming all other revenue recognition criteria have been met, 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 hospital, control of the products transfers to the customer 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. As of March 31, 2021 and December 31, 2020, the Company recorded $263,000 and $498,000, respectively, of unbilled receivables, which are included in accounts receivable, net, in the accompanying balance sheets.

Revenue for ClotTriever and FlowTriever products as a percentage of total revenue was derived as follow:

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 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 and certain direct costs such as shipping costs and royalty expense.

Shipping Costs

Shipping costs billed to customers are not included in revenue and are reported as a reduction of costs of goods sold.

Advertising Costs

Advertising costs are charged to operations as incurred. Advertising costs were $71,000 and $37,000 for the three months ended March 31, 2021 and 2020, respectively. Advertising costs are included in SG&A expenses in the accompanying consolidated statements of operations.

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 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 statements of operations.

Stock-based Compensation

The Company’s employee and non-employee share-based awards result in a cost that is measured at fair value on the awards’ grant date, based on the estimated number of awards that are expected to vest. Stock-based compensation is recognized over the service period.

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. Due to the Company’s historical operating performance and the recorded cumulative net losses in prior fiscal periods, the net deferred tax assets have been 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 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 Transactions

The functional currencies of the Company’s subsidiaries are currencies other than the U.S. dollar. The Company translates assets and liabilities of the foreign subsidiaries into U.S. dollars at the exchange rate in effect on the balance sheet date. Costs and expenses of the subsidiaries are translated into U.S. dollars at the average exchange rate 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 subsidiary at which time the gains or losses will be realized and included in net income (loss).  Certain vendors are paid in currencies other than the US dollar. Transaction gains and losses are included in other expenses and have not been significant for the periods presented.

Comprehensive Income (Loss)

The Company’s  comprehensive income is comprised of net income and changes in unrealized gain and losses on available-for-sale investments 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 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, redeemable convertible preferred stock and warrants, and common stock options 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.

10

Inari Medical, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

The Company allocates no loss to participating securities because they have no contractual obligation to share in the losses of the Company. The shares of the Company’s convertible preferred stock participate in any dividends declared by the Company and are therefore considered to be participating securities.

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 - the development and commercialization of innovative and minimally invasive mechanical thrombectomy devices to treat thromboembolism in the venous system. Geographically, the Company primarily sells to hospitals in the United States. Segment information is consistent with how management reviews the business, makes investing and resource allocation decisions and assesses operating performance.

Recently Adopted Accounting Pronouncements

In June 2018, the FASB issued ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which expands guidance on accounting for share-based payment awards, which includes share-based payment transactions for acquiring goods and services from nonemployees and aligns the accounting for share-based payments for employees and non-employees. The Company adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In February 2017, the FASB issued ASU 2017-02, Leases (Topic 842) (“ASC 842”), as amended, which requires lessees to recognize “right of use” assets and liabilities for all leases with terms of more than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2017-02 requires additional quantitative and qualitative financial statement note disclosures about the leases, significant judgments made in accounting for those leases and amounts recognized in the financial statements about those leases.

The Company adopted the requirement of ASC 842 effective January 1, 2021 and elected the modified retrospective method for all lease arrangements with a cumulative-effect adjustment as of January 1, 2021. Results for reporting periods beginning on or after January 1, 2021 are presented under ASC 842, while prior period amounts were not adjusted and are reported in accordance with the Company’s historic accounting under ASC 840, Leases. For leases that commenced before the effective date of ASC 842, the Company elected the transition package of three practical expedients permitted within ASC 842, which eliminates the requirements to reassess prior conclusions about lease identification, lease classification, and initial direct costs. The Company also elected the hindsight practical expedient, which permits the use of hindsight when determining lease term and impairment of right-of-use assets. Further, the Company elected a short-term lease exception policy, permitting the Company to not apply the recognition requirements of this standard to short-term leases (i.e., leases with terms of 12 months or less) and an accounting policy to account for lease and non-lease components as a single component for certain classes of assets.  

The Company determines if an arrangement is a lease at inception. As a lessee, right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent an obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As the Company does not have any outstanding debt or committed credit facilities, the Company estimates the incremental borrowing rate based on prevailing financial market conditions, peer company credit analyses, and management judgment. Operating lease right-of-use assets also include any lease payments made at or before lease commencement and exclude any lease incentives received. The lease terms used to calculate the right-of-use asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense, while the expense for finance leases is recognized as amortization expense and interest expense using the accelerated interest method of recognition.

As a result of adopting ASC 842 as of January 1, 2021, the Company recorded an operating lease right-of-use asset of $1.2 million and related operating lease liability of $1.3 million based on the present value of the future lease payments on the date of adoption. There was no cumulative-effect adjustment recorded to retained earnings upon adoption. Adopting ASC 842 did not have a material impact on the Company’s condensed consolidated statements of operations and cash flows. See Note 7, Commitments and Contingencies, for further discussion of the Company’s adoption of ASC 842 and related disclosures.

In December 2019, the FASB issued ASU 2019-12, Income Taxes – Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by clarifying and amending existing guidance related to the recognition of franchise tax, the evaluation of a step-up in the tax basis of goodwill and the effects of enacted changes in tax laws or rates in the effective tax rate computation, among other clarifications. ASU 2019-12 is effective for annual periods beginning after December 15, 2020, including

interim periods within those fiscal years, and early adoption is permitted. The Company adopted this guidance effective January 1, 2021 and the adoption of this standard did not have a material impact on its consolidated financial statements.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13 Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model, which requires the use of forward-looking information to calculate credit loss estimates. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in earlier recognition of credit losses. The guidance will be effective for the Company on January 1, 2023 with early adoption permitted. Management is evaluating the impact that adopting this guidance will have on the consolidated financial statements.

Capitalized Implementation Costs of a Hosting Arrangement

The Company has several software systems that are cloud based hosting arrangements with service contracts. The Company accounts for costs incurred in connection with the implementation of these various software systems under ASU 2018-15, Intangibles—Goodwill and Other-Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The Company expenses all costs (internal and external) that are incurred in the planning and post-implementation operation stages and has capitalized approximately $479,000 in implementation costs related to the application development stage. The capitalized costs are amortized on a straight-line basis over the non-cancelable contract terms, generally three years. As of March 31, 2021 and December 31, 2020, approximately $223,000 and $228,000, respectively, of the capitalized costs were classified in current assets and $99,000 and $0, respectively, were classified in noncurrent assets. The Company starts amortizing capitalized implementation costs when the systems are placed in production and ready for their intended use. Amortization expense for the three months ended March 31, 2021 and 2020 was approximately $41,000 and $23,000, respectively, and is included in SG&A expenses.

7. 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 entered into or reassessed after the adoption of ASC 842, the Company combines lease and non-lease components. See Note 2, Summary of Significant Accounting Policies for additional information.

In March 2019, the Company executed a five-year lease for a facility in Irvine, California, where substantially all operations of the Company have been located since September 2019. The lease expires in September 2024 and contains two optional extension periods of five years each. In addition to the minimum future lease commitments presented below, the lease requires the Company to pay property taxes, insurance, maintenance, and repair costs. The lease includes a one-month rent holiday concession and escalation clauses for increased rent over the lease term. Concurrent with the execution of a new ten-year lease (see below), the Company entered into a termination agreement (as amended) that releases the Company from the current facility lease obligation 12 months following the commencement date of the new lease, with options to extend the lease term for up to three periods of an additional 30 days each. The Company recognized an operating lease right-of-use asset of $828,000 and an aggregate lease liability of $921,000 on its March 31, 2021 condensed consolidated balance sheet. The remaining lease term is estimated to be 16 months.

In October 2020, the Company entered into a ten-year lease for a facility in Irvine, California (the “Oak Canyon lease”). The Company estimates that the Oak Canyon lease will have a lease commencement date in the second or third quarter of 2021. The Oak Canyon lease contains two optional extension periods of five years each. The Oak Canyon lease requires the Company to make variable lease payments for property taxes, insurance, maintenance, and repair costs. The Oak Canyon lease includes scheduled payment escalation clauses over the lease term. In connection with this lease, the Company has budgeted approximately $28 million of

tenant improvement costs, $4.5 million of which is required to be funded by the related landlord. Because a significant portion of the tenant improvements have been deemed to be assets of the landlord and were under construction as of March 31, 2021, the Company has not yet taken control of the leased facility and the lease has not yet commenced. The Oak Canyon lease requires that the Company maintain a letter of credit for the benefit of the landlord in the amount of $1.5 million, which is secured by the Company’s Credit Agreement.

The Company also leases two additional warehouse spaces located in Lake Forest, California and Irvine, California. In connection with the warehouse leases, the Company recognized an operating lease right-of-use asset of $91,000 and a lease liability of $91,000 on its March 31, 2021 condensed consolidated balance sheet. The weighted average remaining lease term is 16 months.

The Company also leases certain equipment for warehouse and office use. In connection with the equipment leases, the Company recognized an operating lease right-of-use asset of $127,000 and a lease liability of $127,000 on its March 31, 2021 condensed consolidated balance sheet. The weighted average remaining lease term is 51 months.  

The weighted average incremental borrowing rate used to measure operating lease liabilities is 2.81%.

Rent expense under the lease agreements for the three months ended March 31, 2021 and 2020 was $185,000 and $154,000, respectively. Future minimum lease payments under operating leases liabilities as of March 31, 2021 are as follows (in thousands):

The following are minimum future rental payments owed for the Oak Canyon lease which has not yet commenced as of March 31, 2021 (in thousands):

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.

9. Related Party

Licensed Patents

Certain stockholders of the Company are stockholders of Inceptus Medical, Inc. (“Inceptus”). Beginning in September 2011, the Company engaged Inceptus to develop the technology that has led to certain components used in the Company’s products, the FlowTriever and the ClotTriever systems. In October 2014, the Company, through a license agreement with Inceptus, obtained an exclusive, perpetual, fully paid-up irrevocable, worldwide license to the patents, patent applications and technology, including the right to grant and authorize sublicenses, to make, have made, use, sell, offer for sale, import and otherwise exploit products in connection with the licensed technology. The licensed technology is any and all technology involving a high wire count braid, excluding the tubular braiding subject to the sublicense agreement described below.

Sublicense Agreement

In August 2019, the Company entered into a sublicense agreement with 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; such rights were originally granted to Inceptus pursuant to an intellectual property license agreement with Drexel University, or Drexel License, under which Drexel retained certain rights to use, and to permit other non-commercial entities to use, the sublicensed intellectual property for educational and non-commercial research purposes. The Company is obligated to comply with, and to avoid acts or omissions that would reasonably be likely to cause a breach of the Drexel License. The sublicense agreement will continue until the expiration of the sublicensed patent, unless terminated earlier pursuant to the terms of the agreement. The Company may terminate the sublicense agreement at any time by providing prior written notice.

Under the sublicense agreement, the Company is required to pay an ongoing quarterly administration fee, which amounted to $29,000 and $18,000 for the three months ended March 31, 2021 and 2020, respectively. Additionally, the Company is obligated to pay Inceptus 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 $1,000. For the three months ended March 31, 2021 and 2020, the Company recorded royalty expense of $190,000 and $90,000, respectively.

Other Services

The Company utilizes MRI The Hoffman Group (“MRI”), a recruiting services company owned by the brother of the Chief Executive Officer and President and member of the board of directors of the Company.

10. Debt

Bank of America Credit Facility

In September 2020, the Company entered into a senior secured revolving credit facility with Bank of America (the “Credit Agreement”), as amended, under which the Company may borrow loans up to a maximum principal amount of $30 million. The amount available to borrow under the Credit Agreement is comprised of a) 85% of eligible accounts receivable, plus b) pledged cash (up to $10 million).  There was no principal amount outstanding and no cash was pledged under the Credit Agreement as of March 31, 2021 and December 31, 2020.

Advances under the 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 LIBOR rate based upon an interest period of 30 days plus 1.00%. The Margin was 1.25% until March 31, 2021 and thereafter, will range from 1.00% to 1.50% based on the Company’s applicable fixed charge coverage ratio. Advances under the Credit Agreement designated as “LIBOR Loans” will bear interest at a rate per annum equal to the LIBOR rate plus the applicable Margin of 2.25% until March 31, 2021 and thereafter, ranging from 2.00% to 2.50% based on the Company’s applicable fixed charge coverage ratio.  Interest on loans outstanding under the Credit Agreement is payable monthly. Loan principal balances outstanding under the Credit Agreement are due at maturity in September 2023. The Company may prepay any loans under the Credit Agreement at any time without any penalty or premium. The Company is also required to pay an unused line fee at an annual rate ranging from 0.25% to 0.375% per annum of the average daily unused portion of the aggregate revolving credit commitments under the Credit Agreement.

The Credit Agreement also includes a Letter of Credit subline facility (the “LC Facility”) of up to $5 million. The aggregate stated amount outstanding of letter of credits reduces the total borrowing base available under the Credit Agreement.  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 LIBOR 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.  As of March 31, 2021, the Company had two letters of credit in the aggregate amount of $1.8 million outstanding under the LC Facility. As of December 31, 2020, the Company had one letter of credit in the amount of $1.5 million outstanding under the LC Facility.

The Company paid Bank of America a closing fee of $150,000 and incurred approximately $290,000 in legal and other fees directly related to the Credit Agreement.  The Credit Agreement contains certain customary covenants and events of default, including: payment defaults, breaches of any representation, warranty or covenants, judgment defaults, cross defaults to certain other contracts, certain events with respect to governmental approvals if such events could cause a material adverse change, a material impairment in the perfection or priority of the lender's security interest or in the value of the collateral, a material adverse change in the business, operations, or condition of us or any of our subsidiaries, and a material impairment of the prospect of repayment of the loans. Upon the occurrence of an event of default, a default increase in the interest rate of an additional 2.0% could be applied to the outstanding loan balance and the lender could declare all outstanding obligations immediately due and payable and take such other actions as set forth in the loan and security agreement. The Company was in compliance with its covenant requirements as of March 31, 2021. Obligations under the Credit Agreement are secured by substantially the Company’s assets, excluding intellectual property.  

Signature Bank Credit Facility

In December 2019, the Company entered into a $40 million credit facility with Signature Bank (the “SB Credit Facility”) and concurrently repaid and extinguished its term loan with East West Bank. The SB Credit Facility consisted of a term loan of up to $25 million and a revolving line of credit of $15 million. The term loan was available in two tranches: a $15 million tranche that was fully funded on the closing date, and a $10 million tranche that was available through December 2020. In March 2020, the Company borrowed an additional $10 million which was available under the term loan.

The maturity date of the term loan was in December 2024. Under the agreement, the Company was required to make monthly interest payments through December 2021. The term loan bore interest at an annual rate equal to the greater of 5.50% or the Prime Rate plus 0.50%. Under the revolving line of credit, the Company could borrow, repay and re-borrow up to 80% of eligible accounts receivable up to a maximum of $15 million. The revolving line of credit bore interest at an annual rate equal to the greater of 5.00% or the prime rate.

In August 2020, the Company repaid the SB Credit Facility in full.

Deferred Financing Costs

As of March 31, 2021 and December 31, 2020, costs incurred directly related to debt are presented in other assets and are being amortized over the three-year life of the Credit Agreement on the straight-line basis as follows (in thousands):

11. Stockholder’s Equity

Redeemable Convertible Preferred Stock

In connection with the IPO in May 2020, the 31,968,570 shares of redeemable convertible preferred stock then outstanding were converted into 31,968,570 shares of common stock.

Authorized Stock

As of March 31, 2021, the Company had authorized 310,000,000 shares of stock, of which 300,000,000 shares are designated as common stock and 10,000,000 shares are designated as preferred stock. All stock has a par value of $0.001 per share.  There were no shares of preferred stock outstanding as of March 31, 2021 and December 31, 2020.

Warrants

There were no warrants outstanding as of March 31, 2021 and December 30, 2020. The Company had previously issued common stock warrants and redeemable convertible preferred stock warrants (“Preferred Warrants”) allowed the holders to obtain shares of redeemable convertible preferred stock that contain a liquidation preference. Because this liquidation preference may have been payable in cash upon a change in control of the Company or upon exercise of redemption rights and because such a transaction was considered to be outside of the control of the Company, the Preferred Warrants were classified as liabilities in the Company’s consolidated balance sheets and were presented at their estimated fair values at each reporting date.  On the completion of the IPO, all the outstanding Preferred Warrants were converted into warrants to purchase an aggregate of 256,588 shares of common stock, which resulted in the reclassification of the convertible preferred stock warrant liability to additional paid-in capital.

In June 2020, 27,810 common stock warrants were exercised for cash.  In addition, 77,030 warrants were net exercised and the Company issued 74,723 shares of common stock. In November 2020, the remaining 179,558 warrants were net exercised and the Company issued 174,776 shares of common stock.

The fair value of the Preferred Warrants was determined using the Black Scholes option pricing model with the following assumptions:

12. Equity Incentive Plans

2011 Equity Incentive Plan and 2020 Incentive Award Plan

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, directors, consultants and advisors. 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 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 March 31, 2021, there were 4,762,853 shares available for issuance under the 2020 Plan, including 1,477,548 additional shares reserved effective January 1, 2021.

Stock Options

A summary of stock option activity under the 2011 Plan for the three months ended March 31, 2021 is as follows (intrinsic value in thousands):

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.

The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

Restricted Stock Units

In March 2019, the Company granted, under the 2011 Plan, 2,867,326 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. The performance-based condition is a liquidity event requirement that was satisfied on the effective date of the IPO of the Company’s common stock. The RSUs are subject to a four-year cliff vesting and will vest in March 2023. If the RSUs vest, the actual number of RSUs that will vest will be dependent on the per share value of the Company’s common stock, which is a market-based condition, determined based on the average closing price of the Company’s common stock for the three-month period immediately preceding the satisfaction of the service condition.

2020 Plan

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 activity under the 2020 Plan is set forth below (intrinsic value in thousands):

Total compensation cost for all share-based payment arrangements recognized, including $597,000 and $0 of stock-based compensation expense related to the ESPP for three months ended March 31, 2021 and 2020, respectively, was as follows (in thousands):

Total compensation costs as of March 31, 2021 related to all non-vested awards to be recognized in future periods was $42,033,000 and is expected to be recognized over the remaining weighted average period of 3.6 years.

Employee Share Purchase Plan (ESPP)

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. The Company has initially reserved 990,870 shares of common stock for purchase under the ESPP. 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 and ended on January 31, 2021. 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:

Inari Medical, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

As of March 31, 2021, 36,881 shares of common stock have been purchased under the ESPP and 1,446,505 shares are reserved for future purchases.

13. Income Taxes

The following table reflects the Company’s provision (benefit) for income taxes for the periods indicated (in thousands):

The Company’s effective tax was 2.6% and 0% for the three months ended March 31, 2021 and 2020, respectively. The Company’s effective tax rate for all periods is driven by pre-tax income, business credits, equity compensation, state taxes, and the change in valuation allowance. Tax provision expense of $198,000 and $0 was recorded for the three months ended March 31, 2021 and 2020, respectively.

Valuation Allowance

ASC 740 requires that the tax benefit of net operating losses, or NOLs, 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 carryback or carryforward periods.  As of December 31, 2020, the Company maintained a full valuation allowance of $11.9 million against the Company's net deferred tax assets. As of March 31, 2021, the Company believes that the deferred tax assets are currently not considered more likely than not to be realized and, accordingly, has maintained a full valuation allowance against its net deferred tax assets.  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 would result in the recognition of certain deferred tax assets and a decrease to income tax expense for the period the release is recorded. However, the timing and amount of the valuation allowance release, if any, is uncertain and based on various factors.

Uncertain Tax Positions

The Company has recorded uncertain tax positions related to its federal and California research and development credit carryforwards. No interest or penalties have been recorded related to the uncertain tax positions due to available NOLs to offset the uncertain tax positions. 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 as well as to 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 tax examinations in progress. The statute of limitations for tax years ended after December 31, 2015 and December 31, 2016 are open for state and federal tax purposes, respectively.

Taxpayer Certainty and Disaster Tax Relief Act of 2020

The Taxpayer Certainty and Disaster Tax Relief Act of 2020 ("the Act"), was enacted on December 27, 2020. It was a response to continued market volatility and instability resulting from the coronavirus pandemic and includes provisions to support businesses in the form of loans, grants, and tax changes, among other types of relief. The Company has reviewed and incorporated the income tax changes included in the Act, including the deductibility of meals expenses previously not deductible for tax purposes. The Company does not believe there will be a material effect on the its income tax provision.  The Company currently does not expect to apply for loans or grants expanded by the Act.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes included in this Quarterly Report on Form 10-Q and our audited financial statements and related notes thereto for the year ended December 31, 2020, included in our Annual report on form 10-K.

Overview

We are a commercial-stage medical device company focused on developing products to treat and transform the lives of patients suffering from venous diseases. Our primary product offering consists of two minimally-invasive, novel catheter-based mechanical thrombectomy devices. We purpose-built our products for the specific characteristics of the venous system and the treatment of the two distinct manifestations of venous thromboembolism, or VTE – deep vein thrombosis and pulmonary embolism. Our ClotTriever product is FDA-cleared for the treatment of DVT. Our FlowTriever product is the first thrombectomy system FDA-cleared for the treatment of pulmonary embolism, or PE, and is also FDA-cleared for clot in transit in the right atrium.

We believe the best way to treat VTE and improve the quality of life of patients suffering from this disease is to safely and effectively remove the blood clot. With that in mind, we designed and purpose-built our ClotTriever and FlowTriever products to remove large clots from large vessels and eliminate the need for thrombolytic drugs. We believe our products are transformational and could be the catalyst to drive an evolution of treatment for venous diseases, establishing our products as the standard of care for DVT and PE.

We believe our venous-focused commercial organization provides a significant competitive advantage. Our most important relationships are between our sales representatives and our treating physicians, which include interventional cardiologists, interventional radiologists and vascular surgeons. We have developed systems and processes to harness the information gained from these relationships and we leverage this information to rapidly iterate products, introduce and execute physician education and training programs and scale our sales organization. We market and sell our products to hospitals, which are reimbursed by various third-party payors. We have dedicated meaningful resources to building a direct sales force in the United States, and we continue to expand our sales organization through additional sales representatives and territories.

On May 27, 2020, we completed our IPO, which resulted in the issuance and sale of 9,432,949 shares of common stock, including 1,230,384 shares sold pursuant to the exercise of the underwriters’ over-allotment option, at the IPO price of $19.00 per share. We received net proceeds of approximately $163.0 million from the IPO, after deducting underwriters’ discounts and commissions of $12.6 million and offering costs of $3.7 million.

Prior to our IPO, our primary sources of capital were private placements of preferred stock, debt financing arrangements and revenue from sales of our products. Since inception, we had raised a total of approximately $54.2 million in net proceeds from private placements of preferred stock. As of March 31, 2021, we had cash, cash equivalents, and short-term investment of $174.1 million, no long-term debt outstanding and an accumulated deficit of $20.0 million.

For the three months ended March 31, 2021, we generated revenue of $57.4 million, with a gross margin of 91.9% and net income of $7.5 million, compared to revenue of $27.0 million, with a gross margin of 90.0% and net income of $4.1 million for the three months ended March 31, 2020.

COVID-19

In December 2019, a novel strain of coronavirus, SARS-CoV-2, was identified in Wuhan, China. Since then, SARS-CoV-2, and the resulting disease, COVID-19, has spread to most countries, including all 50 states in the United States. The global healthcare system continues to face an unprecedented challenge as a result of the COVID-19 situation and its impact. COVID-19 has had and may continue to have an adverse impact on aspects of our Company and business, including the demand for our products, our operations, and the ability to research and develop and bring to market new products and services.

In response to the pandemic, in March 2020, many governmental authorities suspended or canceled elective, specialty and other procedures and appointments, and some states and countries issued “stay at home” orders limiting non-essential activities, travel and business operations. These orders significantly decreased the number of procedures performed using our products during March and April 2020 and otherwise negatively impacted our operations.  In response to the impact of COVID-19, we implemented a variety of measures to help manage through the impact and position us to resume operations quickly and efficiently once these restrictions were lifted. The results for the first quarter of 2021 reflect some recovery from the declines we experienced in the first quarter of 2020. However, with cases continuing to resurge in certain areas, and hospitals at capacity in some instances due to non-COVID-19 treatments, to the extent individuals and hospital systems de-prioritize, delay or cancel deferrable medical procedures, our business, cash flows, financial condition and results of operations may continue to be negatively affected.

In addition, COVID-19 has strained hospital systems around the world, resulting in adverse financial impacts to those systems, which has resulted in and may continue to result in reduced expenditures for the products we provide and may adversely affect the

collectability of our current and future accounts receivable balance. We continue to actively monitor the COVID-19 situation and its impact.

While we are encouraged by our first quarter results, we are aware that the actual and perceived impact of COVID-19 is changing and cannot be predicted. As a result, we cannot assure you that our recent procedure volumes are indicative of future results or that we will not experience additional negative impacts associated with COVID-19, which could be significant. We continue to focus our efforts on the health and safety of patients, healthcare providers and employees, while executing our mission of transforming lives of VTE patients. While we expect the COVID-19 pandemic may continue to negatively impact 2021 performance, we believe the long-term fundamentals remain strong and we will continue to effectively manage through these challenges.

Procedure Volume

We regularly review various operating and financial metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate our business plan and make strategic decisions. We believe the number of procedures performed to treat DVT and PE using our products is an indicator of our ability to drive adoption and generate revenue. We believe this is an important metric for our business; however, we anticipate that additional metrics may become important as our business grows. The following table lists the number of procedures performed in each of the three-month periods as indicated:

Components of our Results of Operations

Revenue

We currently derive all our revenue from the sale of our ClotTriever and FlowTriever products to hospitals primarily in the United States. Our customers typically purchase an initial stocking order of our products and then reorder replenishment product as procedures are performed. No single customer accounted for 10% or more of our revenue during the three months ended March 31, 2021 and 2020. For the three months ended March 31, 2021, approximately 61% of our customers used both of our products, 30% used ClotTriever only and 9% used FlowTriever only. We expect revenue to increase in absolute dollars as we expand our sales organization and sales territories, add customers, expand the base of physicians that are trained to use our products, expand awareness of our products with new and existing customers and as physicians perform more procedures using our products. Revenue for ClotTriever and FlowTriever products as a percentage of total revenue is as follows:

For the three months ended March 31, 2021 and 2020, our blended revenue per procedure was approximately $9,300 and $9,100. Blended revenue per procedure represents the average of the average selling price per ClotTriever and the average price per FlowTriever procedure.

Cost of Goods Sold and Gross Margin

We manufacture and/or assemble all our products at our facility in Irvine, California. 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 and certain direct costs such as shipping costs and royalty expense. Shipping costs billed to customers are reported as a reduction of cost of goods sold. We expect cost of goods sold to increase in absolute dollars as our revenue grows and more of our products are sold, however, we also expect to realize opportunities to increase operating leverage in our manufacturing operations.

24

We calculate gross margin as gross profit divided by revenue. Our gross margin has been and will continue to be affected by a variety of factors, including average selling prices, product sales mix, production and ordering volumes, manufacturing costs, product yields, headcount and cost-reduction strategies. Our gross margin could fluctuate from quarter to quarter as we introduce new products, adopt new manufacturing processes and technologies, and as we expand internationally.

Treatments using the FlowTriever may involve one or more Triever aspiration catheters and one or more FlowTriever catheters. We charge customers the same price for each FlowTriever procedure, regardless of the number of components used. As a result, changes in the number of components used, the cost of these components and the introduction of additional components can impact our gross margin.

Research and Development Expenses

Research and development, or R&D, expenses consist primarily of engineering, product development, clinical studies to develop and support our products, regulatory expenses, and other costs associated with products that are in development. These expenses include employee compensation, including stock-based compensation, supplies, consulting, prototyping, testing, materials, travel expenses, depreciation and an allocation of facility overhead expenses. Additionally, R&D expenses include costs associated with our clinical trials and registries, including clinical study design, clinical study site initiation and study costs, data management, and internal and external costs associated with our regulatory compliance, including the costs of outside consultants and contractors that assist in the process of submitting and maintaining regulatory filings. We expense R&D costs as incurred. We expect R&D expenses as a percentage of revenue to vary over time depending on the level and timing of our new product development efforts, as well as our clinical development, clinical trials and registries and other related activities.

Selling, General and Administrative Expenses

Selling, general and administrative, or SG&A, expenses consist primarily of compensation for personnel, including stock-based compensation, related to selling and marketing functions, physician education programs, commercial operations and analytics, finance, information technology and human resource functions. Other SG&A expenses include sales commissions, travel expenses, promotional activities, marketing initiatives, market research and analysis, conferences and trade shows, physician training, professional services fees (including legal, audit and tax fees), insurance costs, general corporate expenses and facilities-related expenses. We expect SG&A expenses to continue to increase in absolute dollars as we expand our sales and marketing organization and infrastructure to both drive and support the anticipated growth in revenue and due to additional legal, accounting, insurance and other expenses associated with being a public company.

Interest Income

Interest income consists primarily of interest income earned on our cash, cash equivalents and short-term investments.

Interest Expense

Interest expense consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to the amortization of debt discount and issuance costs associated with our indebtedness.

Change in Fair Value of Warrant Liabilities

Change in fair value of warrant liabilities consists of gains and losses resulting from the remeasurement of the fair value of our preferred stock warrant liabilities at each balance sheet date. Upon the closing of our IPO, our outstanding preferred stock warrants automatically converted into warrants to purchase shares of our common stock. At such time, the final fair value of the warrant liability was reclassified to stockholders’ equity (deficit). We will no longer record any related periodic fair value adjustments.

Results of Operations

Comparison of the three months ended March 31, 2021 and 2020

The following table sets forth the components of our unaudited statements of operations in dollars and as percentage of revenue for the periods presented (dollars in thousands):

Revenue. Revenue increased $30.4 million, or 113%, to $57.4 million during the three months ended March 31, 2021, compared to $27.0 million during the three months ended March 31, 2020. The increase in revenue was due primarily to an increase in the number of products sold. The increase in revenue was offset in part by the negative impact of the COVID-19 pandemic on procedure volume and new orders during the three months ended March 31, 2021.Revenue for the three months ended March 31, 2020 was also negatively impacted by a rapid deceleration in the number of products sold in March due to the COVID-19 pandemic.

Cost of Goods Sold and Gross Margin. Cost of goods sold increased $1.9 million, or 71%, to $4.6 million during the three months ended March 31, 2021, compared to $2.7 million during the three months ended March 31, 2020. This increase was due to the increase in the number of products sold and additional manufacturing overhead costs incurred as we invested significantly in our operational infrastructure to support anticipated future growth. Gross margin for the three months ended March 31, 2021 increased to 91.9%, compared to 90.0% for the three months ended March 31, 2020, due to an increase in the average selling prices of our products and improved operating leverage.

Research and Development Expenses. R&D expenses increased $5.2 million, or 170%, to $8.2 million during the three months ended March 31, 2021, compared to $3.0 million during the three months ended March 31, 2020. The increase in R&D expenses was primarily due to increases of $3.5 million of personnel-related expenses, $0.9 million in materials and supplies, $0.5 million of clinical study and registry expenses, and $0.1 million in professional fees, in support of our growth drivers to increase our new product pipeline and build the clinical evidence base.
