The accompanying interim financial statements should be read in conjunction with the Company’s audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, ~~2020~~2021 filed with the SEC. All intercompany accounts and transactions have been eliminated in consolidation.

~~Reclassification~~—In the quarter ended September 30, 2021, the Company changed the presentation of its condensed consolidated statement of operations and comprehensive income (loss) to separately disclose the change in contingent consideration, previously reported in selling, general and administrative expenses. Amounts for comparative prior fiscal periodsThere have been ~~reclassified to conform to the current period presentation. This reclassification had~~ no ~~impact on previously reported net income or financial position.~~

~~Cash and Cash Equivalents~~—The Company considers highly liquid investments with maturities of three months or less at the date of purchase as cash equivalents. Cash equivalents include demand deposits, money market funds and repurchase agreements on deposit with financial institutions.

~~Investments~~—The Company invests primarily in government and agency obligations, corporate bonds, commercial paper and asset-backed securities and classifies all investments as available-for-sale. Investments maturing in less than one year are classified as short-term investments. Investments are recorded at fair value, with unrealized gains and losses recorded as accumulated other comprehensive income (loss). Gains and losses are recognized using the specific identification method when securities are sold and are included in interest income.

~~Revenue Recognition—~~The Company recognizes revenue when control of promised goods is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods. This generally occurs upon shipment of goods to customers. See Note 8 for further discussion on revenue.

~~Sales Returns and Allowances~~—The Company maintains a provision for potential returns of defective or damaged products and invoice adjustments. The Company adjusts the provision using the expected value method based on historical experience. Increases to the provision reduce revenue, and the provision is included in accrued liabilities.

~~Allowance for Credit Losses on Accounts Receivable~~—The Company evaluates the expected credit losses on 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. The Company charges off uncollectible receivables against the allowance when all attempts to collect the receivable have failed. The Company’s history of write-offs has not been significant.

~~Inventories~~—Inventories are stated at the lower of cost or net realizable value based on the first-in, first-out cost method (FIFO) and consist of raw materials, work in process and finished goods. The Company’s industry is characterized by rapid product development and frequent new product introductions. Uncertain timing of regulatory approvals, variability in product launch strategies and variation in product use all impact inventory reserves for excess, obsolete and expired products. An increase to inventory reserves results in a corresponding increase in cost of revenue. Inventories are written off against the reserve when they are physically disposed.

~~Inventories consist of the following:~~

September 30,
2021 December 31,
2020
Raw materials $ 13,053 $ 11,966
Work in process 3,357 2,424
Finished goods 22,177 20,636
Inventories $ 38,587 $ 35,026

~~Property and Equipment~~—Property and equipment is stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of assets. The estimated useful life by major asset category is the following:


			~~Estimated Useful Life~~
~~Generators and related equipment~~			~~1 - 3 years~~
~~Building and building under finance lease~~			~~15 - 20 years~~
~~Computers, software and office equipment~~			~~3 - 5 years~~
~~Machinery and equipment~~			~~3 - 7 years~~
~~Furniture and fixtures~~			~~3 - 7 years~~
~~Leasehold improvements~~			~~5 - 15 years~~
~~Equipment under finance leases~~			~~3 - 5 years~~

The Company assesses the useful lives of property and equipment at least annually and retires assets no longer in use. Maintenance and repair costs are expensed as incurred. The Company reviews property and equipment for impairment at least annually using its best estimates based on reasonable and supportable assumptions and expected future cash flows. Property and equipment impairments have not been significant.

The Company’s radiofrequency (RF) and cryo generators are generally placed with customers that use the Company’s disposable products. The estimated useful lives of generators are based on anticipated usage by customers and may change in future periods with changes in ~~usage or introduction of new technology. Depreciation of generators and related equipment, which is included in cost of revenue, was $532 and $613~~the Company's significant accounting policies for the three months ended ~~September 30, 2021 and 2020 and $1,735 and $1,898~~March 31, 2022 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the ~~nine months~~year ended ~~September 30, 2021 and 2020. As of September 30, 2021 and~~ December 31, ~~2020, the net carrying value of generators and related equipment included in net property and equipment was $3,609 and $3,410.~~

~~Leases~~— The Company leases office, manufacturing and warehouse facilities and computer equipment under leases that qualify as either financing or operating leases, as determined at the inception of the lease arrangement. Lease assets represent the right to use an underlying asset for the lease term, and lease liabilities represent the obligation to make lease payments arising from the lease. Lease assets and liabilities are measured and recorded at the commencement date based on the present value of lease payments over the lease term.

Lease assets and liabilities exclude lease incentives and include options to extend or terminate when it is reasonably certain the Company will exercise that option. The Company uses the implicit rate when readily determinable; however, as most leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at measurement. The Company also applies the short-term lease recognition exemption, recognizing lease payments in profit or loss, for leases that have a lease term of 12 months or less at commencement and do not include an option to extend the lease whose exercise is reasonably certain. For real estate and equipment leases, the Company accounts for the lease and non-lease components as a single lease component. Additionally, the portfolio approach is applied for the operating leases based on the terms of the underlying leases.

Operating leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities, while finance leases are included in property and equipment and finance lease liabilities. The short-term portions of both lease liabilities are included in other current liabilities and current maturities of debt and leases. Operating lease expense is recognized on a straight-line basis over the lease term. See Note 6 for further discussion.

~~Intangible Assets~~—Intangible assets with determinable useful lives are amortized on a straight-line basis over the estimated periods benefited. Intangible assets include In Process Research and Development (IPR&D), representing the value of technology acquired in business combinations that has not yet reached technological feasibility. The primary basis for determining technological feasibility is obtaining specific regulatory approvals. IPR&D is accounted for as an indefinite-lived intangible asset until completion or abandonment of the IPR&D project. Upon completion of the development project, IPR&D will be amortized over its estimated useful life. Due to the nature of IPR&D projects, the Company may experience future delays or failures to obtain regulatory approvals or market clearances, or may discontinue or abandon the project, all which may impact the estimated fair value of the IPR&D project. As a result, the Company may have a full or partial impairment charge related to the IPR&D, calculated as the excess carrying value of the IPR&D asset over the estimated fair value.

The Company reviews intangible assets at least annually for impairment using its best estimates based on reasonable and supportable assumptions and projections. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present.

~~Through April~~ 2021 the IPR&D asset included an estimate of the fair value of the pre-market approval (PMA) that could result from the CONVERGE IDE and aMAZE™ IDE clinical trials. The Company received PMA approval for CONVERGE on April 28, 2021 and began amortizing the $44,021 technology asset over an estimated fifteen year life. During the third quarter 2021, the Company identified indicators of impairment for the IPR&D asset that represents an estimate of the fair value of the PMA that could result from the aMAZE clinical trial. As a result of the analysis performed, the Company recorded an impairment loss of $82,300. See Note 3 for further discussion.

~~Goodwill—~~Goodwill represents the excess of purchase price over the fair value of the net assets acquired in business combinations. The Company’s goodwill is accounted for in a single reporting unit representing the Company as a whole. The Company performs impairment testing annually on October 1 or more often if impairment indicators are present.

~~Contingent Consideration and Other Noncurrent Liabilities—~~This balance consists of contingent consideration from business combinations, as well as deferred payroll taxes as a result of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act), asset retirement obligations and other contractual obligations. The contingent consideration balance is included in noncurrent liabilities as any settlement is expected to be made primarily in shares of the Company’s common stock pursuant to the SentreHEART, Inc. (SentreHEART) merger agreement. See Note 2 for further discussion.

~~Other Income (Expense)~~—Other income (expense) consists primarily of foreign currency transaction gains and losses generated by settlements of intercompany balances denominated in Euros and customer invoices transacted in British Pounds.

~~Taxes~~—Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities from a change in tax rates is recognized in the period that includes the enactment date.

The Company’s estimate of the valuation allowance for deferred income tax assets requires significant estimates and judgments about future operating results. Deferred income tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more-likely-than-not that the deferred income tax asset will not be realized. Significant weight is given to evidence that can be objectively verified. The Company evaluates deferred income tax assets on an annual basis to determine if valuation allowances are required. Deferred income tax assets are realized by having sufficient future taxable income to allow the related tax benefits to reduce taxes otherwise payable. The sources of taxable income that may be available to realize the benefit of deferred income tax assets are future taxable income, future reversals of existing taxable temporary differences, carryforwards and tax planning strategies that are both prudent and feasible. In evaluating the need for a valuation allowance, the existence of cumulative losses in recent years is significant objectively verifiable negative evidence that must be overcome by objectively verifiable positive evidence to avoid the need for a valuation allowance. The Company has established a full valuation allowance against substantially all net deferred income tax assets as it is more-likely-than-not that the benefit of the deferred income tax assets will not be recognized in future periods. The Company has not reclassified income tax effects of the Tax Cuts and Jobs Act within accumulated other comprehensive income (loss) to retained earnings due to its full valuation allowance.

~~Earnings Per Share~~—Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflects net income available to common stockholders divided by the weighted average number of common shares outstanding during the period and any dilutive common share equivalents, including shares issuable upon the vesting of restricted stock awards and restricted stock units, exercise of stock options as well as shares issuable under the Company's employee stock purchase plan (ESPP).

Net income (loss) available to common stockholders $ 97,108 $ (4,949) $ 63,940 $ (29,593)
Basic weighted average common shares outstanding 45,258 44,012 44,977 41,442

Diluted net income (loss) per common share $ 2.11 $ (0.11) $ 1.39 $ (0.71)

For the three and nine months ended September 30, 2020, net loss per share excludes the effect of 2,687 shares because the effect would be anti-dilutive. The computation of diluted earnings per share in the three and nine month periods ended September 30, 2021 excludes 491 and 582 shares because the effect would be anti-dilutive.

~~Comprehensive Income (Loss) and Accumulated Other Comprehensive Income (Loss)—In addition to net income (loss), the comprehensive income (loss) includes foreign currency translation adjustments and unrealized gains (losses) on investments.~~

~~Accumulated other comprehensive income (loss) consisted of the following, net of tax:~~

~~Research and Development Costs—Research and development costs are expensed as incurred. These costs include compensation and other internal and external costs associated~~filed with the ~~development and research of new and existing products or concepts, preclinical studies, clinical trials and related regulatory activities, as well as amortization of technology assets.~~SEC.

~~Advertising Costs~~—~~The Company expenses advertising costs as incurred. Advertising costs were not significant during the three and nine months ended September 30, 2021 and 2020.~~

~~Share-Based Compensation~~—The Company records share-based compensation for all share-based payment awards, including stock options, restricted stock awards, restricted stock units, performance shares (PSAs) and stock purchases related to an employee stock purchase plan, based on estimated fair values. The value of the portion of an award that is ultimately expected to vest, net of estimated forfeitures, is recognized as expense over the service period. The Company estimates forfeitures at the time of grant and revises them, as necessary, in subsequent periods as actual forfeitures differ from those estimates. The Company recognized share-based compensation expense of $6,794 and $5,549 for the three months ended September 30, 2021 and 2020 and $20,539 and $16,126 for the nine months ended September 30, 2021 and 2020.

The Company estimates the fair value of time-based options on the date of grant using the Black-Scholes option-pricing model (Black-Scholes model). The Company’s determination of the fair value is affected by the Company’s stock price as well as several subjective assumptions, such as the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. The Company estimates the fair value of restricted stock awards and restricted stock units based upon the grant date closing market price of the Company’s common stock.

The Company estimates the fair value of PSAs with a performance condition based on the closing stock price on the date of grant assuming the performance goal will be achieved and may adjust expense over the performance period based on changes to estimates of performance target achievement. If such goals are not met or service is not rendered for the requisite service period, no compensation cost is recognized, and any recognized compensation cost will be reversed. For PSAs with a market condition, a Monte Carlo simulation is performed to estimate the fair value on the date of grant, and compensation cost is recognized over the requisite service period as the employee renders service, even if the market condition is not satisfied. The Company’s determination of the fair value is affected by the Company and the peer group’s stock price, as defined by the award agreement, at the beginning of the service period and grant date, the expected volatility of the Company and peer group’s stock price over the performance period and the correlation coefficient of the daily returns for the Company and peer group over the performance period.

The Company also has an employee stock purchase plan (ESPP) which is available to all eligible employees as defined by the plan document. Under the ESPP, shares of the Company’s common stock may be purchased at a discount. The Company estimates the number of shares to be purchased under the ESPP at the beginning of each purchase period based upon the fair value of the stock at the beginning of the purchase period using the Black-Scholes model and records estimated compensation expense during the purchase period. Expense is adjusted at the time of stock purchase.

Use of Estimates—The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, including intangible assets, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting period. Estimates are based on historical experience, where applicable, and other assumptions believed to be reasonable by management. Actual results could differ from those estimates.

Segments—The chief operating decision maker for the Company is the Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis, accompanied only by information about revenue by product type and geographic area, for purposes of allocating resources and evaluating financial performance. Accordingly, the Company has determined that it has a single operating segment. The Company’s long-lived assets are located primarily in the United States, except for $1,321 as of March 31, 2022 and $1,399 as of December 31, 2021 located primarily in Europe.

Net Loss Per Share—Basic and diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common shares outstanding during the period. Since the Company has experienced net losses for all periods presented, net loss per share excludes the effect of 1,567 and 1,955 stock options, restricted shares, restricted stock units and performance award shares as of March 31, 2022 and 2021 because they are anti-dilutive. Therefore, the number of shares calculated for basic net loss per share is also used for the diluted net loss per share calculation.

2.FAIR VALUE

The Financial Accounting Standards Board’s (FASB) Accounting Standards Codification (ASC) 820, “Fair Value Measurements and Disclosures” (ASC 820), defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three

~~Table of Contents~~

~~ATRICURE, INC. AND SUBSIDIARIES~~

~~NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS~~

~~(In Thousands, except per share amounts)~~

~~(Unaudited)~~

levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value:

•Level 1—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.

(In Thousands, except per share amounts)

(Unaudited)

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

The Company classifies cash and investments in government and agency obligations, accounts receivable, short-term other assets, accounts payable and accrued liabilities as Level 1 within the fair value hierarchy. The carrying amounts of these assets and liabilities approximate their fair value due to their relatively short-term nature. Cash equivalents and investments in corporate bonds, commercial paper and asset-backed securities are classified as Level 2 within the fair value hierarchy. The fair value of fixed term debt is estimated by calculating the net present value of future debt payments at current market interest rates and is classified as Level 2. The book value of the Company’s fixed term debt approximates its fair value because the interest rate varies with market rates.

Contingent Consideration. The Company’s contingent consideration arrangements arising from the SentreHEART acquisition obligate the Company to pay certain defined amounts to former shareholders of SentreHEART if specified milestones are met related to the aMAZE IDE clinical trial, including PMA approval and reimbursement for the therapy involving SentreHEART’s devices. ~~As of December 31, 2020, the terms of the contingent consideration arrangements under the nContact merger agreement expired.~~

The Company measures contingent consideration liabilities using unobservable inputs by applying the probability-weighted scenario method, an income approach. Various key assumptions, such as the probability and timing of achievement of the agreed milestones, are significant to the determination of fair value of contingent consideration arrangements and are not observable in the market, thus representing a Level 3 measurement within the fair value hierarchy. Contingent consideration liabilities are periodically measured, with changes in the estimated fair value reflected in operating expenses. Changes in the discount rate, projected time until payment and probability of payment may result in materially different fair value measurements. A decrease in the discount rate would result in a higher fair value measurement, while a decrease in the probability of payment would result in a lower fair value measurement. Movement in the forecasted timing of achievement to later in the milestone periods would cause a decrease in the fair value measurement.

In July 2021, the Company was informed that data from the aMAZE clinical trial did not achieve statistical superiority. Specifically, while the trial met the safety endpoint, the trial did not meet the primary efficacy endpoint. As the contingent consideration arrangements were success-based milestone payments, the fair value of the SentreHEART contingent consideration was remeasured as of September 30, 2021 resulting in a decrease in fair value due to changes in estimates related to both the forecasted timing and probability of achievement of the regulatory and reimbursement milestones. Specifically, the Companyhas assessed the projected probability of payment during the contractual achievement periods to be remote, ~~as of September 30, 2021,~~ resulting in no remaining fair ~~value. Accordingly, the Company recorded a credit to operating expenses~~value as of ~~$189,900 in the third quarter 2021, reflecting the change in fair value of the contingent consideration during the three months ended September 30,~~March 31, 2022 and December 31, 2021.

Estimated Useful Life Cost Accumulated
Amortization Cost Accumulated
Amortization
Technology 5 - 15 years $ 55,712 $ 11,749 $ 11,691 $ 9,813
IPR&D — — 126,321 —
Total $ 55,712 $ 11,749 $ 138,012 $ 9,813

~~Following PMA approval of the EPi-Sense~~® System in the second quarter 2021, the related IPR&D asset with a value of $44,021 was determined to have a finite useful life. The intangible asset is now included in technology assets and is amortized over an estimated fifteen year life.

As a result of data from the aMAZE clinical trial not achieving statistical superiority, the Company identified indicators of impairment for the IPR&D asset that represents an estimate of the fair value of the PMA that could result from the aMAZE clinical trial. During the third quarter 2021, an impairment test was performed using estimates based on reasonable and supportable assumptions and projections of expected future cash flows, and the Company recorded an impairment charge of $82,300, reducing the carrying value of the aMAZE IPR&D asset to $0 at September 30, 2021. This impairment charge is reflected as a component of operating expenses.

Amortization expense of intangible assets with definite lives, which excludes IPR&D assets, was $971 and $467 for the three months ended September 30, 2021 and 2020 and $1,936 and $1,444 for the nine months ended September 30, 2021 and 2020.

~~Future amortization expense is projected as follows:~~

Parties to the royalty ~~agreements~~agreement have the right at any time to terminate the agreement immediately for cause. Royalty expense of ~~$792~~$794 and ~~$699~~$722 was recorded as a component of Cost of Revenue in the accompanying Condensed and Consolidated Statement of Operations for the three months ended ~~September 30, 2021~~March 31, 2022 and ~~2020 and $2,356 and $1,880 for the nine months ended September 30, 2021 and 2020.~~2021.

Purchase Agreements. The Company enters into standard purchase agreements with vendors in the ordinary course of business, generally with terms that allow cancellation. The Company is committed to funding renovation of a recently purchased building for additional manufacturing capacity. The Company estimates the cost of the construction project to be approximately $5,500.

Legal. The Company may, from time to time, become a party to legal proceedings. Such matters are subject to many uncertainties and to outcomes of which the financial impacts are not predictable with assurance and that may not be known for extended periods of time. A liability is established once management determines a loss is probable and an amount ~~that~~ can be reasonably estimated.

The Company received a Civil Investigative Demand (CID) from the U.S. Department of Justice (USDOJ) in December 2017 stating that it is investigating the Company to determine whether the Company has violated the False Claims Act, relating to the promotion of certain medical devices related to the treatment of atrial fibrillation for off-label use and submitted or caused to be submitted false claims to certain federal and state health care programs for medically unnecessary healthcare services related to the treatment of atrial fibrillation. The CID covers the period from January 2010 to December 2017 and required the production of documents and answers to written interrogatories. The Company had no knowledge of the investigation prior to receipt of the CID. The Company maintains rigorous policies and procedures to promote compliance with the False Claims Act and other applicable regulatory requirements. The Company provided the USDOJ with documents and answers to the written interrogatories. In March 2021, USDOJ informed the Company that its investigation was based on a lawsuit brought on behalf of the United States and the various state and local ~~governments~~government under the qui tam provisions of federal and certain state and local False Claims Acts. Although the USDOJ and all of the state and local governments declined to intervene, the relator continues to pursue the case. ~~The~~While the Company is vigorously contesting the case, ~~however,~~ it is not possible to predict when this matter may be resolved or what impact, if any, the outcome of this matter might have on our consolidated financial position, results of operations, or cash flows.

The Company acquired nContact Surgical, Inc. pursuant to a merger agreement dated October 4, 2015. The merger agreement provided for contingent consideration or “earnout” to be paid upon attaining specified regulatory approvals and clinical and revenue milestones. The merger agreement’s earnout provisions requiredDuring the ~~Company to deliver periodic earnout reports to a designated representative of former nContact stockholders. In response to the reports delivered in and after February 2018,~~first quarter, the Company received ~~letters from representatives purporting~~a notice of breach under a license agreement regarding its potential underpayment of royalties. The notice asserts that the Company's calculation of royalties payable under the license agreement throughout the agreement term did not include sales of all products that were subject to ~~serve~~royalties. The Company disputes the basis of the claim and any potential underpayment. While a loss related to this claim is possible, the Company does not believe such loss is probable or estimable at this time.

9.REVENUE

The Company develops, manufactures and sells devices designed primarily for the surgical ablation of cardiac tissue, the exclusion of the left atrial appendage, and blocking pain by temporarily ablating peripheral nerves. These devices are developed and marketed to a broad base of medical centers globally. The Company recognizes revenue when control of promised goods is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods.

In the quarter ended March 31, 2022, the Company changed the presentation of its disaggregated revenue within the notes to the Condensed Consolidated Financial Statements to align with current product line offerings. Specifically, pain management revenue, representing sales of the cryoSPHERE® product, was historically presented within open ablation revenue and is now a separately stated revenue product type. Valve revenue, historically presented as ~~“earnout objection statements” (as that term~~a separate product type revenue, is ~~defined~~now included in open ablation revenue. Revenue amounts for comparative prior fiscal periods have been reclassified to conform to the ~~merger agreement) and claim that for purposes of determining the commercial milestone payment, the~~current period presentation.

8.~~REVENUE~~

Revenue is generated primarily from the sale of medical devices. The Company recognizes revenue in an amount that reflects the consideration the Company expects to be entitled to in exchange for those devices when control of promised devices is transferred to customers. At contract inception, the Company assesses the products promised in its contracts with customers and identifies a performance obligation for each promise to transfer to the customer a product that is distinct. The Company’s devices are distinct and represent performance obligations. These performance obligations are satisfied, and revenue is recognized at a point in time upon shipment or delivery of products. Sales of devices are categorized as follows: open ablation, minimally invasive ablation, appendage management and valve tools. Shipping and handling activities performed after control over products transfers to customers are considered activities to fulfill the promise to transfer the products rather than as separate promises to customers.

Products are sold primarily through a direct sales force and through distributors in certain international markets. Terms of sale are generally consistent for both end-users and distributors except that payment terms are generally net 30 days for end-users and net 60 days for distributors, with some exceptions. The Company does not maintain any post-shipping obligations to customers. No installation, calibration or testing of products is performed by the Company subsequent to shipment in order to render products operational.

Significant judgments and estimates involved in the Company’s recognition of revenue include the estimation of a provision for returns. The Company estimates the provision for sales returns and allowances using the expected value method based on historical experience and other factors that we believe could impact our expected returns, including defective or damaged products and invoice adjustments. In the normal course of business, the Company generally does not accept product returns unless a product is defective as manufactured. The Company does not provide customers with the right to a refund.

The Company expects to be entitled to the total consideration for the products ordered by customers as product pricing is fixed according to the terms of customer contracts and payment terms are short. Payment terms fall within the one-year guidance for the practical expedient which allows the Company to forgo adjustment of the promised amount of consideration for the effects of a significant financing component. The Company excludes taxes assessed by governmental authorities on revenue-producing transactions from the measurement of the transaction price.

Costs associated with product sales include commissions and royalties. Considering that product sales are performance obligations in contracts that are satisfied at a point in time, commission expense associated with product sales and royalties paid based on sales of certain products is incurred at that point in time rather than over time. Therefore, the Company applies the practical expedient and recognizes commissions and royalties as expense when incurred because the expense is incurred at a point in time and the amortization period is less than one year. Commissions are included in selling expense while royalties are included in cost of revenue.

~~See Note 11 for disaggregated revenue by geographic area and by product category.~~

9.10.INCOME TAX PROVISION

The Company files federal, state and foreign income tax returns in jurisdictions with varying statutes of limitations. The Company uses the asset and liability method to determine its provision for income taxes. The Company’s provision for income taxes in interim periods is computed by applying the discrete method and is based on financial results through the end of the interim period. The Company determined that using the discrete method is more appropriate than using the annual effective tax rate method. The Company is unable to estimate the annual effective tax rate with sufficient precision to use the effective tax rate method, which requires a full-year projection of income. The effective tax rate for the three months ended ~~September 30,~~March 31, 2022 and 2021 was (0.37%) and ~~2020 was 0.04% and 0.08%~~(0.18%). ~~The effective tax rate for the nine months ended September 30, 2021 and 2020 was 0.21% and (0.05%)~~ The Company’s worldwide effective tax rate differs from the US statutory rate of 21% primarily due to the Company’s valuation ~~allowance in the United States and Netherlands.~~

allowance.

Federal, state and local returns of the Company are routinely subject to review by various taxing authorities. The Company has not accrued any interest and penalties related to unrecognized income tax benefits as a result of offsetting of net operating losses. However, if required, the Company will recognize interest and penalties within income tax expense and within the related tax liability.

~~10.~~11.EQUITY COMPENSATION PLANS

The Company has 2 share-based incentive plans: the 2014 Stock Incentive Plan (2014 Plan) and the ~~2018~~2019 Employee Stock Purchase Plan (ESPP).

Stock Incentive Plan

Under the 2014 Plan, the Board of Directors may grant incentive stock options to Company employees and may grant restricted stock awards, or restricted stock units, ~~(collectively RSAs),~~ nonstatutory stock options, performance share awards ~~(PSAs) or~~and stock appreciation rights to Company employees, directors and consultants. The Compensation Committee of the Board of Directors, as the administrator of the 2014 Plan, has the authority to determine the terms of any awards, including the number of shares subject to each award, the exercisability of the awards and the form of consideration. As of ~~September 30, 2021,~~March 31, 2022, 12,899 shares of common stock had been reserved for issuance under the 2014 Plan, and ~~1,471~~1,152 shares were available for future grants.

Stock options, restricted stock awards and restricted stock units granted generally vest at a rate of 33.3% on the first, second and third anniversaries of the grant date. Stock options generally expire ten years from the date of grant.

The award agreements for the PSAs provide that each PSA that vests represents the right to receive 1 share of the Company’s common stock at the end of the performance period. With respect to the PSAs, the number of shares that vest and are issued to the recipient is based upon the Company’s performance with respect to specified targets at the end of the three year performance period. Payout opportunities range from 0% to 100% of the target amount for awards granted prior to 2021, while awards granted in 2021 have payout opportunities ranging from 0% to 200% of the target amount. These ranges are used to calculate the number of shares that will be issuable when the award vests. All or a portion of the PSAs may vest following a change of control or a termination of service by reason of death or disability. PSAs granted prior to 2021 have performance targets based on the Company’s revenue compound annual growth rate (CAGR) over the three year performance period. PSAs granted in 2021 have two equally weighted performance targets measured at the end of the three year performance period: (i) the Company’s revenue CAGR; and (ii) relative total shareholder return (TSR). TSR is measured against the Nasdaq Health Care Index constituents and the 20-trading-day average stock price prior to the end of the performance period over the 20- trading-day average stock price prior to the beginning of the performance period. The performance and market condition payouts will be determined independently and accumulated to determine the total payout for the three year performance period, subject to the maximum payout defined in the PSA agreements.

Employee Stock Purchase Plan

Under the ESPP, shares of the Company’s common stock may be purchased at a discount (15%) of the lesser of the closing price of the Company’s common stock on the first ~~trading day~~ or ~~the~~ last trading ~~day~~days of the offering period. The offering period (currently six months) and the offering price are subject to change. Participants may not purchase a value of more than $25 of the Company’s common stock in a calendar year and may not purchase ~~a value of~~ more than 3 shares during an offering period. As of ~~September 30, 2021,~~March 31, 2022, there were ~~338~~305 shares available for future issuance under the ESPP.

Overview

We are a leading innovator in treatments for atrial fibrillation (Afib) ~~and~~, left atrial appendage (LAA) management and post-operative pain management. According to the American Heart Association, Afib affects 1-2% of the population in the United States. It is the most common cardiac arrhythmia, or irregular heartbeat, encountered in clinical practice and results in high utilization of healthcare services. Patients often progress from being in Afib intermittently (paroxysmal) to being in Afib continuously. The continuous Afib patient population includes persistent Afib, which lasts seven days to one year, and long-standing persistent Afib, which lasts longer than one year. Afib often occurs in conjunction with other cardiovascular diseases, including hypertension, congestive heart failure, left ventricular dysfunction, coronary artery disease and valvular disease. Our ablation and left atrial appendage management (LAAM) products are used by physicians during both open-heart and minimally invasive procedures. In open-heart procedures, the physician is performing heart surgery for other conditions, and our products are used in conjunction with (“concomitant” to) such a procedure. Minimally invasive procedures are performed on a standalone basis, and often include multi-disciplinary or “hybrid” approaches, combining both surgical procedures using AtriCure ablation and LAAM products and catheter ablation.

We ~~have several product lines for~~believe that we are currently the ~~ablation~~market leader in the surgical treatment of ~~cardiac tissue, including our~~Afib. Our Isolator® Synergy™ Ablation System is approved by the United States Food and Drug Administration (FDA) for the treatment of persistent and long-standing persistent ~~forms of~~ Afib concomitant to other open-heart surgical procedures. The EPi-Sense® ~~system~~System is approved by FDA to treat patients with long-standing persistent Afib. All of our other ablation devices are ~~approved~~cleared for sale in the United States under FDA 510(k) clearances, including our other RFradio frequency (RF) and cryoablation products, which are indicated for the ablation of cardiac tissue and/or the treatment of cardiac arrhythmias.

Recent Developments

~~Throughout 2020 and the beginning of the first quarter of 2021,~~During early 2022, we experienced ~~a significant decrease in~~variability and intermittent demand for our products asnon-emergent procedures were ~~being indeterminately~~ deferred in order to preserve resources for COVID-19 patients and caregivers and hospital staffing was impacted by the pandemic and related factors. We expect this variability to ~~protect patients from potential exposure to COVID-19. While~~continue as we ~~have seen~~operate in many geographic regions with diverse restrictions that are impacted as new COVID-19 variants emerge. However, we saw many regions ~~begin to~~ stabilize at the end of the first quarter of 2022 with improvements in procedure volumes, there continues to be variability throughout our markets and uncertainty as variants of the virus emerge. We can make no assurance regarding any future level of demand for our products, and COVID-19 may adversely impact our results of operations and financial condition.

We are continuing to serve our customers while taking every precaution to provide a safe work environment for our employees and customers. Field-based sales and clinical employees continue to support cases, using technology to engage with customers in virtual settings when physical access is prohibited. We are maintaining manufacturing and fulfillment operations to continue providing products to our customers. We continue to modify our remote working protocols and evaluate hybrid work models for our office-based employees, and we will take further actions in the best interests of our employees or as required by law.

volumes. Despite the challenging environment resulting from the pandemic, we continue to build on our strategic initiatives of product innovation, investing in clinical science and expanding awareness and adoption by providing superior training and education. ~~We remain confident in our liquidity position, which includes cash and investments of $224,843 as of September 30, 2021, and access to additional funding through our credit facility.~~

PRODUCT INNOVATION. ~~In July 2021,~~Recently, we ~~received~~announced the launch of the new EnCompass Clamp®, following the receipt of 510(k) clearance for ~~the new ENCOMPASS~~® ~~clamp, and we have initiated a limited product launch.~~ablation of cardiac tissue during cardiac surgery in July 2021. The ~~ENCOMPASS~~EnCompass clamp marks innovation in our core open ablation market and is designed to make concomitant surgical ablations more efficient. It is expected to drive deeper penetration of cardiac surgery procedures.

~~TRAINING~~. Our professional education and marketing teams have adapted to the pandemic by conducting online and mobile trainings for physicians and our sales team. These adaptations expanded our training methods and ensured invaluable access to continuing education and awareness of our products and related procedures. The recent FDA approval of the EPi-Sense system has enabled us to educate and train physicians on the benefits of Hybrid AF™ therapy in treating long-standing persistent Afib patients. The first of several training courses planned for 2021 was held in June.

CLINICAL SCIENCE. We continue to invest in studies to expand labeling claims or support indications for the treatment of Afib, and we also conduct various studies to gather clinical data regarding our products.

HEAL-IST. In February 2022, FDA approved the protocol for the Hybrid Epicardial and Endocardial Sinus Node Sparing Ablation Therapy for Inappropriate Sinus Tachycardia, (HEAL-IST) clinical trial. The HEAL-IST clinical trial is designed to study the safety and efficacy of a hybrid sinus node sparing ablation procedure using the Isolator Synergy Surgical Ablation System for the treatment of symptomatic, drug refractory or drug intolerant IST. The trial is a prospective, multicenter, single arm trial that evaluates safety 30 days post-procedure and evaluates primary effectiveness of freedom from IST at 12 months post-procedure. The trial provides for enrollment of up to 142 patients at up to 40 sites in the United States, United Kingdom and European Union. The Company anticipates enrollment to begin this year.

LeAAPS. In April 2022, FDA approved the protocol for the Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction (LeAAPS) IDE clinical trial. The trial is designed to evaluate the effectiveness of prophylactic LAA exclusion using the AtriClip LAA Exclusion System for the prevention of ischemic stroke or systemic arterial embolism in cardiac surgery patients without pre-operative AF diagnosis who are at risk for these events. The trial is a prospective, multicenter, randomized trial that evaluates safety at 30 days post-procedure to demonstrate no increased risk with LAA exclusion during cardiac surgery. The trial provides for enrollment of up to 6,500 subjects at up to 250 sites worldwide. The Company anticipates enrollment to begin this year.

TRAINING. Our professional education and marketing teams conduct virtual, in-person and mobile training for physicians and our sales team. These training methods ensure invaluable access to continuing education and awareness of our products and related procedures. The 2021 ~~we announced the PMA~~FDA approval of the EPi-Sense system ~~for treatment~~has enabled us to educate and train physicians on the benefits of ~~symptomatic, drug-refractory, long-standing persistent atrial fibrillation, when augmented with an endocardial ablation catheter. We believe the Convergent procedure, or~~ Hybrid AFAF™ therapy ~~provides the only compelling treatment option for a large and vastly underpenetrated patient population. The CONVERGE™ trial demonstrated superiority~~ in ~~the hybrid therapy arm compared to endocardial catheter ablation alone. In patients diagnosed with~~treating long-standing persistent Afib the hybrid therapy arm showed a 29% absolute difference in efficacy at 12 months (78% relative improvement) and an absolute difference of 35% at 18 months (110% relative improvement). There was also a 33% absolute difference in Afib burden reduction in favor of the hybrid AF therapy at 12 months, which increased to 37% at 18 months.

~~aMAZE.~~ ~~Enrollment was completed in December 2019. Patient follow-up for twelve months post pulmonary vein isolation catheter ablation~~patients. Our Hybrid Training Course is ~~required~~co-sponsored by the ~~study protocol and was completed in April 2021.~~ In January 2020, we received approval for a Continued Access Protocol (CAP) for the aMAZE study. The aMAZE CAP provides for additional enrollment of up to 85 patients at existing aMAZE trial sites, with the opportunity to further expand to 250 patients while the PMA application is under review. In July 2021, the Company was informed that data from the aMAZE clinical trial did not achieve statistical superiority. Specifically, while the trial met the safety endpoint, the trial did not meet the primary efficacy endpoint. The Company has paused enrollment in the aMAZE CAP, and is in the process of further analyzing aMAZE trial data and determining next steps for the trial, PMA application and any related future development activities.Hearth Rhythm Society (HRS).

Worldwide revenue increased 28.7% (28.6% on a constant currency basis) reflecting an upturn in activity within each franchise and across our key markets globally from an improvement in cardiac surgery procedure volumes over 2020 as well as increasing adoption of our products. Revenue from customers in the United States increased $12,836, or 28.7% while revenue from international customers increased $2,867 or 28.5% (27.9%25.8% (26.7% on a constant currency basis). In the United States, we experienced growth across key product lines and franchises. Appendage management and pain management sales increases were driven by sales of the AtriClip® Flex⋅V® device and cryoSPHERE® probe.

Revenue reported on a constant currency basis is a non-GAAP measure and is calculated by applying previous period foreign currency (Euro) exchange rates, which are determined by the average daily Euro to Dollar exchange rate, to each of the comparable periods. Revenue is analyzed on a constant currency basis to better measure the comparability of results between periods. Because changes in foreign currency exchange rates have a non-operating impact on revenue, we believe that evaluating growth in revenue ~~growth~~ on a constant currency basis provides an additional and meaningful assessment of revenue to both management and ~~our~~ investors.

~~Cost of revenue and gross margin.~~ Cost of revenue increased $8,333, reflecting higher sales volumes, while gross margin increased more than 300 basis points.

~~Research and development expenses.~~ Research and development expenses increased $2,499 or 7.8%. Personnel costs grew $3,979 driven by additional variable compensation and headcount as we continue to build our product development, regulatory, and clinical teams.

~~Table of Contents~~

~~Selling, general and administrative expenses.~~ Selling, general and administrative expenses increased $44,682, or 42.1%. Additional headcount, variable compensation, and travel expenses totaling $32,646 was the largest driver of the increase in expenses.

As a result, training expenses increased $3,975, while tradeshow and marketing activities increased $1,189 as compared to the prior year. Other changes included a $3,212 increase in share-based compensation and a $2,605 increase in legal, professional and consulting expenses.

Liquidity and Capital Resources

As of ~~September 30, 2021,~~March 31, 2022, the Company had cash, cash equivalents and investments of ~~$224,843~~$181,911 and outstanding debt of ~~$58,333.~~$60,000. We had unused borrowing capacity of approximately ~~$10,000~~$28,750 under our revolving credit facility. Most of our operating cash and all cash equivalents and investments are held by United States financial institutions. We had net working capital of ~~$141,753~~$152,232 and an accumulated deficit of ~~$266,412~~$295,336 as of ~~September 30, 2021.~~March 31, 2022.

Cash flows used in operating activities.We Net cash used ~~$14,081 of net cash~~ in operating activities ~~during~~increased $15,316 in 2022 compared to 2021. This change is driven by the nine months ended September 30, 2021. The net cash outflow from operating activities reflects our net income of $63,940, offset by $70,914 of non-cash adjustments, as well as $7,107 net cash used for operatingfluctuation in working capital and other assets and ~~liabilities. Non-cash adjustments reflect~~liabilities of $15,815, driven by the $12,500 reduction in accrued liabilities primarily as a result of higher annual variable compensation payments due to improved operating performance and a $1,254 increase in accounts receivable as a result of sales growth. The remaining fluctuation is a decrease in the net loss of $1,734, driven by a decrease in non-cash expenses of $1,235. Fluctuation in non-cash expenses is largely the $2,500 non-cash impact for the fair value adjustment of the ~~aMAZE trial results contributing to a $184,800 change in value of the~~SentreHEART contingent consideration liability in 2021, offset partially by ~~an $82,300 impairment charge on~~amortization of the ~~aMAZE IPR&D~~CONVERGE technology asset. Other non-cash expenses included $20,539 share-based compensation, as well as $7,608 of depreciation and amortization. Net cash used for operating assets and liabilities was driven by higher customer receivables in the first nine months of 2021 due to the increase in revenue and continued investment in inventories, offset by increases to both accounts payable and accrued liabilities balances, reflecting the increase in inventories, operating expenses and variable compensation as of September 30, 2021.

Credit facility. Our Loan and Security Agreement, as amended and modified effective November 1, 2021 (Loan Agreement) with Silicon Valley Bank (SVB)~~, as amended, (Loan Agreement),~~ provides for a $60,000 term loan, ~~and~~ a ~~$20,000~~$30,000 revolving line of ~~credit. The term loan~~credit, and revolving credit facility both mature or expire, as applicable, on August 1, 2024. The term loan accrues interest at the greater of the Prime Rate or 5.00%, plus 0.75% and is subject to an additional 3.00% fee on the $60,000 term loan principal amount, payable at maturity or upon acceleration or prepayment of the term loan. Our borrowing availability under the revolving credit facility is based on the lesser of $20,000 or a borrowing base calculation as defined by the Loan Agreement. Borrowing availability under the revolving credit facility is further limited by a cap on total debt outstanding under the Loan Agreement, including outstanding letters of credit, of $70,000. As of September 30, 2021 we had no borrowings under the revolving credit facility, and we had borrowing availability approximately of $10,000. The Loan Agreement also provides for certain prepayment and early termination fees if the term loan is repaid before maturity and establishes a minimum liquidity ratio and dividend restrictions, along with other customary terms and conditions. Specified assets have been pledged as collateral. Principal payments on the term loan commenced September 1, 2021 and were made through October 2021.

Uses of liquidity and capital resources. Our executive officers and Board of Directors review our funding sources and future capital requirements in connection with our annual operating plan and periodic updates to the plan. Our future capital requirements depend on a number of factors, including, without limitation: market acceptance of our current and future products; ~~the resources we devote~~costs to ~~developing~~develop and ~~supporting~~support our products, including professional ~~training costs;~~training; future expenses to ~~support~~expand and ~~expand~~support our sales and marketing efforts; operating and filing costs relating to changes in regulatory policies or ~~laws that affect our operations and cost of filings;~~laws; costs ~~associated with~~for clinical trials and ~~securing~~to secure regulatory approval for new products; costs ~~associated with acquiring~~to prosecute, defend and ~~integrating businesses; costs associated with prosecuting, defending and enforcing~~enforce our intellectual property rights; maintenance and enhancements to our information systems and security; and possible acquisitions and joint ~~ventures.~~ventures, including potential business integration costs. We continue to evaluate additional measures to maintain financial flexibility, and we will continue to closely monitor our liquidity and capital resources through the recovery from, and any further disruptions caused by, COVID-19.

~~We have on file with the SEC a shelf registration statement which allows us to sell any combination~~ Our principal cash requirements include costs of senior or subordinated debt securities, common stock, preferred stock, warrants, depository shares and units in one or more offerings should we choose to do so in the future. We expect to maintain the effectiveness of this shelf registration statement for the foreseeable future.

~~We believe that our current cash, cash equivalents and investments, along with the cash we expect to generate or use for~~ operations, ~~or access via our credit facility agreement with SVB, will be sufficient to meet our anticipated cash needs for working capital and~~ capital expenditures, for at least the next twelve months. The SentreHEART acquisition provides for contingent consideration to be paid upon PMA approval before December 2023 and CPT reimbursement before December 2026. Subject to the terms and conditions of the SentreHEART merger agreement, such contingent consideration must be paid primarily in AtriCure common stock, up to a specified maximum number of shares. We do not expect our cash requirements to include significant cash payments for contingent consideration based on likelihood and progress towards achievement of the related success-based milestones and terms of the acquisition agreement over the next twelve months.

~~If our sources of cash are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or~~ debt securities or obtain a revised or additional credit facility. The sale of additional equity or convertible debt securities could result in dilution to our stockholders. If additional funds are raised through the issuance of debt securities, these securities could have rights senior to those associated with our common stock and could contain covenants that would restrict our operations. Finally, our term loan agreement and revolving line of credit require compliance with certain financialservice costs and other covenants. If we are unable to maintain these financing arrangements, we may be required to reduce the scope of our planned research and development, clinical activities and selling, training, education and marketing efforts.contractual obligations.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The preparation of financial statements requires management to make estimates and judgments that affect the reported amounts of assets and liabilities, revenue and expenses and disclosures of contingent assets and liabilities at the date of the financial statements. On a periodic basis, we evaluate our estimates, including those related to sales returns and allowances, ~~accounts receivable,~~ inventories, ~~intangible assets including goodwill, contingent liabilities~~share-based compensation and ~~share-based compensation.~~income taxes. We use authoritative pronouncements, historical experience and other assumptions as the basis for making estimates. Actual results could differ from those estimates under different assumptions or conditions. Our Annual Report on Form 10-K for the fiscal

year ended December 31, ~~2020~~2021 includes additional information about the Company, our operations, our financial position and our critical accounting policies and estimates and should be read in conjunction with this Quarterly Report on Form 10-Q.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the President and Chief Executive Officer (the Principal Executive Officer) and Chief Financial Officer (the Principal Accounting and Financial Officer), has evaluated the effectiveness of the Company’s disclosure controls and procedures, as defined in Rules 13(a)-15(e) and 15(d) -15(e) of the Securities Exchange Act of 1934 as amended (Exchange Act), as of the end of the period covered by this report. Based on this evaluation, we concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in providing reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s forms and rules, and the material information relating to the Company is accumulated and communicated to management, including the President and Chief Executive Officer and the Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures.

Control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that control objectives are met. Because of inherent limitations in all control systems, no evaluation of controls can provide assurance that all control issues and instances of fraud, if any, within a company will be detected. Additionally, controls can be circumvented by individuals, by collusion of two or more people or by management override. Over time, controls can become

Table of Contents

inadequate because of changes in conditions or the degree of compliance may deteriorate. Further, the design of any system of controls is based in part upon assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all future conditions. Because of the inherent limitations in any cost-effective control system, misstatements due to errors or fraud may occur and not be detected.

Changes in Internal Control Over Financial Reporting

In the ordinary course of business, we routinely enhance our information systems by either upgrading current systems or implementing new ones. There were no changes in our internal control over financial reporting that occurred during the three months ended ~~September 30, 2021~~March 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
