AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (In Thousands, except per share amounts) (Unaudited) 1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of the Business —The “Company” or “AtriCure” consists of AtriCure, Inc. and its wholly-owned subsidiaries. The Company is a leading innovator in surgical treatments and therapies for atrial fibrillation (Afib), left atrial appendage (LAA) management and post-operative pain management, and sells its products to medical centers globally through its direct sales force and distributors. Basis of Presentation —The accompanying interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (SEC). All intercompany accounts and transactions have been eliminated in consolidation. The accompanying interim financial statements are unaudited, but in the opinion of the Company’s management, contain all normal, recurring adjustments considered necessary to present fairly the financial position, results of operations and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States of America (GAAP) applicable to interim periods. Certain information and footnote disclosures included in annual financial statements prepared in accordance with GAAP have been omitted or condensed. The Company believes the disclosures herein are adequate to make the information presented not misleading. Results of operations are not necessarily indicative of the results expected for the full year or for any future period. 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, 2023 filed with the SEC. There have been no changes in the Company's significant accounting policies for the three months ended March 31, 2024 as compared to the significant accounting policies described in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. 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 inventories, intangible assets, valuation allowance for deferred income tax assets, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense, including share-based compensation expense. Estimates are based on historical experience, where applicable, and other reasonable assumptions. Actual results could differ from those estimates. Segments —The Company's chief operating decision maker is its Chief Executive Officer, who reviews financial information presented on a consolidated basis, accompanied only by revenue information 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 in the United States, except for $ 3,625 as of March 31, 2024 and $ 3,432 as of December 31, 2023 located primarily in Europe. Earnings Per Share —Basic and diluted net loss per share are computed by dividing the net loss by the weighted average number 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 2,615 and 1,882 shares as of March 31, 2024 and 2023 because they are anti-dilutive. Therefore, the number of shares used for basic and diluted net loss per share are the same. 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 settle 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. 7 Table of Contents ATRICURE, INC. AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (In Thousands, except per share amounts) (Unaudited) The following table represents the Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis as of March 31, 2024: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Total Assets: Money market funds $ — $ 55,411 $ — $ 55,411 Government and agency obligations 12,852 — — 12,852 Corporate bonds — 25,891 — 25,891 Asset-backed securities — 2,247 — 2,247 Total assets $ 12,852 $ 83,549 $ — $ 96,401 There were no changes in the levels or methodology of measurement of financial assets and liabilities during the three months ended March 31, 2024. The following table represents the Company’s fair value hierarchy for its financial assets measured at fair value on a recurring basis as of December 31, 2023: Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Other Unobservable Inputs (Level 3) Total Assets: Money market funds $ — $ 77,864 $ — $ 77,864 Government and agency obligations 12,711 — — 12,711 Corporate bonds — 38,033 — 38,033 Asset-backed securities — 2,231 — 2,231 Total assets $ 12,711 $ 118,128 $ — $ 130,839 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. The PMA approval milestone expired December 31, 2023. The Company assessed the projected probability of payment during the contractual achievement periods to be remote, resulting in no reported fair value as of March 31, 2024 and December 31, 2023. 8 Table of Contents ATRICURE, INC.

INDEBTEDNESS On January 5, 2024, the Company entered into a credit agreement (Credit Agreement) with JPMorgan Chase Bank, N.A., as administrative agent, and JPMorgan Chase Bank, N.A., as bookrunner and lead arranger (JPMCB), and Silicon Valley Bank, a Division of First-Citizens Bank & Trust Company, as Joint Lead Arrangers and Joint Bookrunners, and the lenders party thereto (Lenders). The Credit Agreement provides for an asset based revolving credit facility (ABL Facility) in an amount of up to $ 125,000 . Borrowing availability under the ABL Facility is based on the lesser of $ 125,000 or a borrowing base calculation as defined by the Credit Agreement. The Company may request an increase in the revolving commitment by up to $ 40,000 (not to exceed a total of $ 165,000 ). A portion of the ABL Facility, limited to $ 5,000 , is available for the issuance of letters of credit by JPMCB or other financial institutions. JPMCB in its sole discretion, may create swingline loans by advancing floating rate revolving loans requested. Any such swingline loans will reduce availability under the ABL Facility on a dollar-for-dollar basis. 10 Table of Contents ATRICURE, INC. AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (In Thousands, except per share amounts) (Unaudited) At closing, the Company borrowed $ 61,865 . The proceeds of the ABL Facility were used to terminate the Company’s outstanding indebtedness and final fee under the Loan and Security Agreement with Silicon Valley Bank (SVB Loan Agreement). Certain prepayment and early termination fees under the SVB Loan Agreement were waived at termination. The termination of the SVB Loan Agreement was treated as a debt extinguishment and the resulting loss on debt extinguishment is $ 1,362 . As of March 31, 2024, the Company had borrowings of $ 61,865 and had borrowing capacity of $ 61,885 under the ABL facility. The Credit Agreement has a three-year term, and all outstanding borrowings are due upon maturity of the Credit Agreement on January 5, 2027. Through January 2025, the Company's required minimum utilization of the ABL facility is 40 % of the aggregate revolving commitment or $ 50,000 . Subject to customary exceptions and restrictions, the Company may voluntarily prepay outstanding amounts under the ABL Facility at any time thereafter without premium or penalty. Any voluntary prepayments made will not reduce commitments under the ABL Facility. The Credit Agreement contains mandatory prepayment provisions which require prepayment of amounts outstanding under the ABL Facility upon specified events or Availability shortfall. Future maturities of long-term debt are projected as follows: 2024 (excluding the three months ended March 31, 2024) $ — 2025 — 2026 — 2027 61,865 2028 — Total long-term debt, of which $ 61,865 is noncurrent $ 61,865 The ABL Facility is subject to a facility fee of 0.37 % per annum of the daily available revolving commitment and paid on a quarterly basis. Outstanding amounts under the Credit Agreement bear interest at a rate per annum equal to, at the Company's election: (i) an alternate base rate (ABR) plus an applicable margin or (ii) an adjusted term secured overnight financing rate (SOFR) plus an applicable margin. All swingline loans bear interest at a rate per annum equal to the ABR plus the applicable margin under the Credit Agreement. Alternate base rate is equal to the greater of Prime, the NYFRB Rate plus 0.50 % or Adjusted Term SOFR Rate plus 1.00 %. The applicable margin on borrowings will adjust ranging 1.50 % to 1.75 % per annum for ABR borrowings and from 2.50 % to 2.75 % per annum for SOFR term borrowings determined by the average historical excess availability. Participation and fronting fees are accrued and paid on a quarterly basis. The ABL Facility is secured by the assets of the Company, consisting of personal, tangible or intangible property, including certain outstanding equity interests of the Company’s direct subsidiaries, subject to limitations specified in the Credit Agreement. The Credit Agreement contains customary representations and warranties, events of default and financial, affirmative and negative covenants for facilities of this type, including but not limited to financial covenants relating to a fixed charge coverage ratio, a minimum liquidity requirement and a minimum excess availability requirement, and restrictions on indebtedness, liens, investments and acquisitions, asset dispositions, specified agreements, restricted payments and prepayment of certain indebtedness. 8. LEASES The Company has operating and finance leases for office, manufacturing and warehouse facilities and automobiles. The Company’s leases have remaining lease terms of less than one year to nine years . Options to renew or extend leases beyond their initial term have been excluded from measurement of the right-of-use (ROU) assets and lease liabilities as exercise is not reasonably certain. 11 Table of Contents ATRICURE, INC.

COMMITMENTS AND CONTINGENCIES License Agreement. The Company had been a party to a license agreement that required royalty payments of 5 % of specified product sales. In May 2023, the Company entered into an agreement that terminated the license agreement and the Company's obligations to make royalty payments under the license agreement. Royalty expense of $ 0 and $ 901 was recorded for the three months ended March 31, 2024 and 2023 as a component of Cost of Revenue in the accompanying Condensed Consolidated Statement of Operations. Purchase Agreements. The Company enters into standard purchase agreements with suppliers 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 recognizes income from a favorable resolution of legal proceedings when the associated cash or assets are received. 13 Table of Contents ATRICURE, INC. AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (In Thousands, except per share amounts) (Unaudited) 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 of 2022, the relator filed a Fourth Amended Complaint, which dropped allegations of off-label promotion and 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 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. During the first quarter of 2023, the Company entered into a legal settlement for $ 7,500 in connection with the settlement of claims filed against a competitor. The Company recorded a $ 4,000 gain for the three months ended March 31, 2023 for the proceeds received as a reduction to selling, general and administrative expenses. 10. REVENUE The Company develops, manufactures and sells devices designed primarily for surgical ablation of cardiac tissue, exclusion of the left atrial appendage, and temporarily blocking pain by ablating peripheral nerves. These devices are marketed to a broad base of medical centers globally.

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 March 31, 2024 and 2023 was ( 1.4 %) and ( 1.2 %). The Company’s worldwide effective tax rate differs from the US statutory rate of 21% primarily due to valuation allowances. The Company's federal, state, local and foreign tax returns 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. 12. EQUITY COMPENSATION PLANS The Company has two share-based incentive plans: the 2023 Stock Incentive Plan (2023 Plan) and the 2018 Employee Stock Purchase Plan (ESPP). Stock Incentive Plan Under the 2023 Plan, the Board of Directors may grant restricted stock awards or restricted stock units (collectively RSAs), nonstatutory stock options, performance share awards (PSAs) or stock appreciation rights to Company employees, directors and consultants, and may grant incentive stock options to Company employees. The Compensation Committee of the Board of Directors, as the administrator of the 2023 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 March 31, 2024, 2,287 shares of common stock have been reserved for issuance under the 2023 Plan, and 869 shares were available for future grants. The Company issues registered shares of common stock for stock option exercises, restricted stock grants and performance share award payments. Employee Stock Purchase Plan Under the ESPP, shares of the Company’s common stock may be purchased at a discount ( 15 %) to the lesser of the closing price of the Company’s common stock on the first or last trading day of the offering period. The offering period (currently six months ) and the offering price are subject to change. Participants may not purchase more than $ 25 of the Company’s common stock in a calendar year or more than 3 shares during an offering period.
