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 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.
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.

8.COMMITMENTS AND CONTINGENCIES
RoyaltyLicense Agreement. The Company has a royaltylicense agreement in place with terms that include payment of royalties of 5% of specified product sales. The agreement terminates the later of 2023 or upon expiration of the underlying patents or patent applications, which is expected to occur after 2023. Parties to the royaltylicense agreement have the right at any time to terminate the agreement immediately for cause. Royalty expense of $877$804 and $842$792 was recorded for the three months ended JuneSeptember 30, 2022 and 2021 and $1,670$2,474 and $1,564$2,356 for the sixnine months ended JuneSeptember 30, 2022 and 2021 as a component of Cost of Revenue in the accompanying Condensed and Consolidated Statement of Operations.
Purchase Agreements. The Company enters into standard purchase agreements with vendors in the ordinary course of business, generally with terms that allow cancellation.
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 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 various state and local governments 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. During the third quarter, the relator filed a Fourth Amended Complaint, which dropped allegations of off-label promotion and now alleges that the Company paid illegal kickbacks to healthcare providers in exchange for using or referring the Company’s products, in violation of the federal Anti-Kickback Statute and various comparable state and local laws. While the Company is vigorously contesting the case, 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.
DuringOn August 23, 2022, the first quarter,Cleveland Clinic Foundation (“Clinic”) and IDx Medical, Ltd. (“IDX”) filed a Demand for Arbitration against the Company received a notice of breach under a license agreement regarding its potential underpayment of royalties.

Clinic and IDX allege the Company did not include the revenues from sales of allcertain products in its calculation of royalty payments due under the License Agreement. Clinic and IDX also allege that were subjectthe Company did not provide related notices required under the License Agreement. The Demand for Arbitration requests a declaration that the termination of the License Agreement shall not occur until the expiration of certain patents and that the Company violated the License Agreement’s non-competition provisions. Clinic and IDX claim they are entitled to no less than $6 million plus interest and costs, fees and expenses associated with their claims and future royalties.
The Company disputesdenies the basisallegations of Clinic and IDX. The Company filed its Answering Statement and Counterclaims to the allegations in September 2022, denying each claim and any potential underpayment.counterclaiming for breach of contract, correction of inventorship, declaratory judgment, patent prosecution and legal fees. No dates have been scheduled for this arbitration. While a loss related to this claim is possible, the Company doesis contesting the case, it is not believe such loss is probablepossible to predict when this matter may be resolved or estimable atwhat impact, if any, the outcome of this time.matter might have on our consolidated financial position, results of operations, or cash flows.

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 JuneSeptember 30, 2022 and 2021 was (0.30%(0.38%) and (0.41%)0.04%. The effective tax rate for the sixnine months ended JuneSeptember 30, 2022 and 2021 was (0.34%(0.35%) and (0.29%)0.21%. The Company’s worldwide effective tax rate differs from the US statutory rate of 21% primarily due to the Company’s valuation 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 net operating losses. However, if required, the Company will recognize interest and penalties within income tax expense and within the related tax liability.

11.EQUITY COMPENSATION PLANS
The Company has 2two share-based incentive plans: the 2014 Stock Incentive Plan (2014 Plan) and the 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, restricted stock units, nonstatutory stock options, performance share awards 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 JuneSeptember 30, 2022, 12,89913,999 shares of common stock had been reserved for issuance under the 2014 Plan, and 1,0762,188 shares were available for future grants. At the Company's 2022 Annual Meeting of Stockholders, stockholders approved an amendment to the 2014 Plan increasing the shares authorized under the 2014 Plan by 1,100.
Employee Stock Purchase Plan
Under the ESPP, shares of the Company’s common stock may be purchased at a 15% discount (15%) of the lesser of the closing price of the Company’s common stock on the first or last trading days of the offering period. The offering period (currently six months) and the offering price are subject to change.

Overview
We are a leading innovator in treatments for atrial fibrillation (Afib), left atrial appendage (LAA) management and post-operative pain management. Afib affects 1-2%1% to 2% of the population in the United States and an estimated 3337 million people worldwide. 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 surgical procedures using AtriCure ablation and LAAM products with catheter ablation.

We believe that we are currently the market leader in the surgical treatment of 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 Afib concomitant to other open-heart surgical procedures. Our EPi-Sense® System is approved by FDA to treat patients with long-standing persistent Afib. All of our other ablation devices are cleared for sale in the United States under FDA 510(k) clearances, including our other radio frequency (RF) and cryoablation products, which are indicated for the ablation of cardiac tissue and/or the treatment of cardiac arrhythmias. In addition, certain of our cryoablation probes are cleared for managing pain by temporarily ablating peripheral nerves, or Cryo Nerve Block therapy. Our AtriClip® LAA Exclusion System products are 510(k)-cleared with an indication for the exclusion of the LAA, performed under direct visualization and in conjunction with other cardiac surgical procedures. Direct visualization, in this context, requires that the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope or other appropriate viewing technologies. Studies have

claims or to support indications specifically for the treatment of Afib, prophylactic stroke reduction or other arrhythmias. Our Isolator Synergy clamps, Isolator Synergy pens, Coolrail® linear pen, cryoablation devices, cryoSPHERE® probe, certain products of the AtriClip LAA Exclusion System, the EPi-Sense® system and LARIAT Suture Delivery Devicesystem bear the CE mark and may be commercially distributed throughout the member states of the European Union and other countries that comply with or mirror the Medical Device Directive. Our Isolator Synergy clamps, Isolator Synergy pens, Coolrail linear pen, cryoablation devices and certain products of the AtriClip LAA Exclusion System are available in select Asia-Pacific countries. We anticipate that substantially all of our revenue for the foreseeable future will relate to products we currently sell or are in the process of developing.
We sell our products to medical centers through our direct sales force in the United States and in certain international markets, such as Germany, France, the United Kingdom, the Benelux region and Australia. We also sell our products through distributors who in turn sell our products to medical centers in other international markets. Our business is primarily transacted in U.S. Dollars, with certain exceptions. DirectDollars; direct sales transactions outside the United States are transacted in Euros, British Pounds or Australian Dollars.
Recent Developments
During 2022, we continued to experience variability and intermittent demand for our products as non-emergent procedures were deferred in order to preserve resources for COVID-19 patients and caregivers and hospital staffing was impacted by the pandemic and related factors. We sawBeginning in the second quarter many regions began to stabilize through the quarter with overall improvements in procedure volumes. However, we expect some variability to continue as we operate in many geographic regions with diverse restrictions that are impacted as new COVID-19 variants emerge. Despite the challenging environment resulting from the pandemic, our worldwide revenue in the sixnine months ended JuneSeptember 30, 2022 was $159,105,$242,351, representing an increase of $28,454,$41,240, or 21.8%20.5%, over the first sixnine months of 2021, driven by growing adoption across key product lines. 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.
PRODUCT INNOVATION. During the first half ofIn April 2022 we launched our ENCOMPASSEnCompass® clamp, following the receipt of 510(k) clearance for ablation of cardiac tissue during cardiac surgery in July 2021. The ENCOMPASSEnCompass 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. During September 2022, the Company received final labeling approval for the next generation EPi-Sense ST device that will be launched in the fourth quarter.
CLINICAL SCIENCE. We continue to invest in studies to expand labeling claims, or support various indications for our products, 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 (IST) clinical trial (HEAL-IST) . 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 (as specified) 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. We announced theThe first patient enrollment in the trial occurred in June 2022; site initiation and enrollment is ongoing.
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 aThis 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 later this year.
TRAINING. Our professional education and marketing teams conduct virtual, in-person and mobile training for physicians and other healthcare professionals, as well as our sales teams. These training methods ensure invaluable access to continuing education and awareness of our products and related procedures. The 2021 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. Our Hybrid Training Course and Advanced Hybrid Ablation Training Course are co-sponsored by the Hearth Rhythm Society (HRS).

Worldwide revenue increased 18.4%18.1% (19.8% on a constant currency basis). In the United States, we experienced growth in most of ourall key product lines. Physician acceptanceStrong physician adoption of our cryoSPHERE® probe for post-operative pain management and expanded sales efforts drove growth in pain management revenue. Appendage management sales were driven by continuing adoption of our AtriClip®AtriClip® Flex⋅V® device drove increased pain management and Pro⋅V® devices, whileappendage management sales. Open ablation revenue increased as a result of both procedure volume and additional revenue per procedure from the launchEnCompass clamp. Growth in Epi-Sense System sales, reflecting continuing adoption of the new ENCOMPASS clamp accelerated growthConvergent Hybrid AF Therapy in our open ablation revenue. Whilea growing number of accounts, was offset by a decline in sales of all other legacy minimally invasive devices. Minimally invasive procedures, which are the most elective of our therapies, continue to experience some residual impactsimpact from the pandemic and staffing we saw growing adoption of the EPi-Sense® System in an increasing customer base. The increase in EPi-Sense revenue was largely offset by a decline in revenue from all other minimally invasive ablation products.constraints. International sales increased 17.3% (26.3%4.2% (13.5% on a constant currency basis), primarily a result of rebounding procedure volumes in Europe, primarily in the Netherlands and United Kingdom, and growth in Australia.Australia and Japan. The increase in international revenue was driven mainly by our appendage management business which grew 35.1%19.5%.

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 on a constant currency basis provides an additional and meaningful assessment of revenue to both management and investors.
Cost of revenue and gross margin. Cost of revenue increased $3,712,$3,299, while gross margin remained flat, reflecting the benefit of higher sales volumes while gross margin decreased approximately 70 basis points, reflecting changes in U.S. product mix and cost increases drivenoffset by inflationary and supply chain pressures.cost pressures and shift in product mix to lower margin products.

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; costs to develop and support our products, including professional training; future expenses to expand and support our sales and marketing efforts; operating and filing costs relating to changes in regulatory policies or laws; costs for clinical trials and to secure regulatory approval for new products; costs to prosecute, defend and enforce our intellectual property rights; maintenance and enhancements to our information systems and security; and possible acquisitions and joint 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.COVID-19 and other macroeconomic conditions including, but not limited to, inflationary pressures, rising interest rates and fluctuations in currency exchange rates. Our principal cash requirements include costs of operations, capital expenditures, debt service costs and other 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, inventories, share-based compensation and 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, 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 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 JuneSeptember 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
