NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (amounts in these accompanying notes are presented in thousands, except number of shares and per-share amounts.) Note 1 — The Company Description of the Business Lucid Diagnostics Inc. (“Lucid”, “Lucid Diagnostics” or the “Company”) is a commercial-stage medical diagnostics technology company focused on the millions of patients with gastroesophageal reflux disease (“GERD”), also known as chronic heartburn, acid reflux or simply reflux, who are at risk of developing esophageal precancer and cancer, specifically highly lethal esophageal adenocarcinoma (“EAC”). Lucid is a subsidiary of PAVmed Inc. (“PAVmed”). The Company believes that its flagship product, the EsoGuard Esophageal DNA Test, performed on samples collected with the EsoCheck Esophageal Cell Collection Device, constitutes the first and only commercially available diagnostic test capable of serving as a widespread testing tool for the early detection of esophageal precancer in at-risk GERD patients. EsoGuard is a bisulfite-converted next-generation sequencing (NGS) DNA assay performed on surface esophageal cells collected with EsoCheck. Cell samples, including those collected with EsoCheck, as discussed below, are sent to our laboratory, for testing and analyses using our proprietary EsoGuard NGS DNA assay. EsoCheck is a FDA 510(k) and CE Mark cleared noninvasive swallowable balloon capsule catheter device capable of sampling surface esophageal cells in a less than a five-minute office procedure. It consists of a vitamin pill-sized rigid plastic capsule tethered to a thin silicone catheter from which a soft silicone balloon with textured ridges emerges, when inflated, to gently swab surface esophageal cells. When vacuum suction is applied, the balloon and sampled cells are pulled into the capsule, protecting them from contamination and dilution by cells outside of the targeted region during device withdrawal. The Company believes that this proprietary Collect+Protect™ technology makes EsoCheck the only noninvasive esophageal cell collection device capable of such anatomically targeted and protected sampling. EsoGuard and EsoCheck are based on patented technology licensed by Lucid from Case Western Reserve University (“CWRU”). EsoGuard and EsoCheck have been developed to provide an accurate, non-invasive, patient-friendly test for the early detection of EAC and Barrett’s Esophagus (“BE”), including dysplastic BE and related precursors to EAC in patients with chronic GERD. Note 2 — Liquidity and Going Concern The Company’s management is required to assess an entity’s ability to continue as a going concern within one year of the date of the financial statements being issued. In each reporting period, including interim periods, an entity is required to assess conditions known and reasonably knowable as of the financial statement issuance date to determine whether it is probable an entity will not meet its financial obligations within one year from the financial statement issuance date. Substantial doubt about an entity’s ability to continue as a going concern exists when conditions and events, considered in the aggregate, indicate it is probable the entity will be unable to meet its financial obligations as they become due within one year after the date the financial statements are issued. The Company has financed its operations principally through public and private issuances of its common stock, preferred stock, and debt. The Company is subject to all of the risks and uncertainties typically faced by medical device and diagnostic companies that devote substantially all of their efforts to the commercialization of their initial product and services and ongoing research and development activities and conducting clinical trials. The Company generated $ 1.0 million and $ 2.0 million of revenues for the three and six month periods ended June 30, 2024, respectively, however the Company does not expect to generate positive cash flows from operating activities in the near future. The Company incurred a net loss attributable to Lucid Diagnostics Inc common stockholders of approximately $ 29.1 million and had net cash flows used in operating activities of approximately $ 24.1 million for the six month period ended June 30, 2024. As of June 30, 2024, the Company had working capital of approximately $ 12.0 million, with such working capital inclusive of the Senior Secured Convertible Note classified as a current liability of approximately $ 11.2 million and approximately $ 24.9 million of cash. The Company’s ability to continue operations 12 months beyond the issuance of the financial statements, will depend upon generating substantial revenue that is conditioned upon obtaining positive third-party reimbursement coverage for its EsoGuard Esophageal DNA Test from both government and private health insurance providers, increasing revenue through contracting directly with self-insured employers, and on its ability to raise additional capital through various potential sources including equity and/or debt financings or refinancing existing debt obligations. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the accompanying unaudited condensed consolidated financial statements are issued. 8 Note 3 — Summary of Significant Accounting Policies Significant Accounting Policies The Company’s significant accounting policies are as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on March 25, 2024, except as otherwise noted herein below. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company and its subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”), and applicable rules and regulations of the United States Securities and Exchange Commission (“SEC”), and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company is a consolidated subsidiary of PAVmed, which has financial control of the Company. The Company manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. As permitted under SEC rules, certain footnotes or other financial information normally required by U.S. GAAP have been condensed or omitted. The balance sheet as of December 31, 2023 has been derived from audited consolidated financial statements at such date. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements, and in the opinion of management, include all adjustments, consisting only of routine recurring adjustments, necessary for a fair statement of the Company’s unaudited condensed consolidated financial information. The unaudited condensed consolidated results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the consolidated results to be expected for the year ending December 31, 2024 or for any other interim period or for any other future periods. The accompanying unaudited condensed consolidated financial statements and related unaudited condensed consolidated financial information should be read in conjunction with the Company’s audited consolidated financial statements and related notes thereto as of and for the year ended December 31, 2023 included in the Company’s Annual Report on Form 10-K as filed with the SEC on March 25, 2024. All amounts in the accompanying unaudited condensed consolidated financial statements and the notes thereto are presented in thousands of dollars, if not otherwise noted as being presented in millions of dollars, except for shares and per share amounts. Use of Estimates In preparing the unaudited condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and the determination of corresponding carrying value reserves, if any, and liabilities and the disclosure of contingent losses, as of the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting period. Significant estimates in these unaudited condensed consolidated financial statements include those related to the estimated fair value of debt obligations, stock-based equity awards and intangible assets. Other significant estimates include the estimated incremental borrowing rate, the provision or benefit for income taxes and the corresponding valuation allowance on deferred tax assets. Additionally, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. On an ongoing basis, the Company evaluates its estimates and assumptions. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable. Due to inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in these estimates. Revenue Recognition Revenues are recognized when the satisfaction of the performance obligation occurs, in an amount that reflects the consideration the Company expects to collect in exchange for those services. The Company’s revenue is primarily generated by its laboratory testing services utilizing its EsoGuard Esophageal DNA tests. The services are completed upon release of a patient’s test result to the ordering healthcare provider. Revenue recognized is inclusive of both variable consideration in connection with an individual patient’s third-party insurance coverage policy and fixed consideration in connection with a contracted services arrangement with an unrelated third party legal entity. To determine revenue recognition for the arrangements that the Company determines are within the scope of ASC 606, Revenue from Contracts with Customers, the Company performs the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract and (5) recognize revenue when (or as) the entity satisfies a performance obligation. 9 Note 3 — Summary of Significant Accounting Policies - continued The key aspects considered by the Company include the following: Contracts —The Company’s customer is primarily the patient, but the Company does not enter into a formal reimbursement contract with a patient. The Company establishes a contract with a patient in accordance with other customary business practices, which is the point in time an order is received from a provider and a patient specimen has been returned to the laboratory for testing. Payment terms are a function of a patient’s existing insurance benefits, including the impact of coverage decisions with Center for Medicare & Medicaid Services (“CMS”) and applicable reimbursement contracts established between the Company and payers. However, when a patient is considered self-pay, the Company requires payment from the patient prior to the commencement of the Company’s performance obligations. The Company’s consideration can be deemed variable or fixed depending on the structure of specific payer contracts, and the Company considers collection of such consideration to be probable to the extent that it is unconstrained. Performance obligations —A performance obligation is a promise in a contract to transfer a distinct good or service (or a bundle of goods or services) to the customer. The Company’s contracts have a single performance obligation, which is satisfied upon rendering of services, which culminates in the release of a patient’s test result to the ordering healthcare provider. The Company elects the practical expedient related to the disclosure of unsatisfied performance obligations, as the duration of time between providing testing supplies, the receipt of a sample, and the release of a test result to the ordering healthcare provider is far less than one year. Transaction price —The transaction price is the amount of consideration that the Company expects to collect in exchange for transferring promised goods or services to a customer, excluding amounts collected on behalf of third parties (for example, some sales taxes). The consideration expected to be collected from a contract with a customer may include fixed amounts, variable amounts, or both. If the consideration derived from the contracts is deemed to be variable, the Company estimates the amount of consideration to which it will be entitled in exchange for the promised goods or services. The Company limits the amount of variable consideration included in the transaction price to the unconstrained portion of such consideration. In other words, the Company recognizes revenue up to the amount of variable consideration that is not subject to a significant reversal until additional information is obtained or the uncertainty associated with the additional payments or refunds is subsequently resolved. When the Company does not have significant historical experience or that experience has limited predictive value, the constraint over estimates of variable consideration may result in no revenue being recognized upon delivery of patient EsoGuard test results to the ordering healthcare provider. As such, the Company recognizes revenue up to the amount of variable consideration not subject to a significant reversal until additional information is obtained or the uncertainty associated with additional payments or refunds, if any, is subsequently resolved. Differences between original estimates and subsequent revisions, including final settlements, represent changes in estimated expected variable consideration, with the change in estimate recognized in the period of such revised estimate. With respect to a contracted service arrangement, the fixed consideration revenue is recognized on an as-billed basis upon delivery of the laboratory test report with realization of such fixed consideration deemed probable based upon actual historical experience. Allocate transaction price —The transaction price is allocated entirely to the performance obligation contained within the contract with a customer on the basis of the relative standalone selling prices of each distinct good or service. Practical Expedients —The Company does not adjust the transaction price for the effects of a significant financing component, as at contract inception, the Company expects the collection cycle to be one year or less. Fair Value Option (“FVO”) Election Under a Securities Purchase Agreement dated March 13, 2023, the Company issued a Senior Secured Convertible Note dated March 21, 2023, referred to herein as the “March 2023 Senior Convertible Note”, which is accounted under the “fair value option election” as discussed below. Under Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 815, Derivative and Hedging , (“ASC 815”), a financial instrument containing embedded features and/or options may be required to be bifurcated from the financial instrument host and recognized as separate derivative asset or liability, with the bifurcated derivative asset or liability initially measured at estimated fair value as of the transaction issue date and then subsequently remeasured at estimated fair value as of each reporting period balance sheet date. Alternatively, FASB ASC Topic 825, Financial Instruments , (“ASC 825”) provides for the “fair value option” (“FVO”) election. In this regard, ASC 825-10-15-4 provides for the FVO election (to the extent not otherwise prohibited by ASC 825-10-15-5) to be afforded to financial instruments, wherein the financial instrument is initially measured at estimated fair value as of the transaction issue date and then subsequently remeasured at estimated fair value as of each reporting period balance sheet date, with changes in the estimated fair value recognized as other income (expense) in the statement of operations. The estimated fair value adjustment of the March 2023 Senior Convertible Note, including the component related to accrued interest, is presented in a single line item within other income (expense) in the accompanying unaudited condensed consolidated statement of operations (as provided for by ASC 825-10-50-30(b)). Further, as required by ASC 825-10-45-5, to the extent a portion of the fair value adjustment is attributed to a change in the instrument-specific credit risk, such portion would be recognized as a component of other comprehensive income (“OCI”) (for which there was no such adjustment with respect to the March 2023 Senior Convertible Note). See Note 9, Financial Instruments Fair Value Measurements , with respect to the FVO election; and Note 10, Debt , for a discussion of the March 2023 Senior Convertible Note. 10 Note 3 — Summary of Significant Accounting Policies - continued Reclassifications Certain prior-year amounts have been reclassified to conform to the current year presentation, which includes presenting costs of revenue within operating expenses on the statements of operations, in the unaudited condensed consolidated financial statements and accompanying notes to the unaudited condensed consolidated financial statements. The impact of the reclassifications made to prior year amounts is not material and did not affect net loss. Recent Accounting Standards Updates Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740)—Improvements to Income Tax Disclosures (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively to all annual periods beginning after December 15, 2024. Early adoption is permitted. The Company does not expect the standard to have a significant impact on its unaudited condensed consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280)—Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which require public companies disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The guidance is effective for public entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance is applied retrospectively to all periods presented in the financial statements, unless it is impracticable. The Company does not expect the standard to have a significant impact on its unaudited condensed consolidated financial statements. In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. This update modifies the disclosure or presentation requirements of a variety of topics in the Accounting Standards Codification to conform with certain SEC amendments in Release No. 33-10532, Disclosure Update and Simplification. The amendments in this update should be applied prospectively, and the effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or S-K becomes effective. However, if the SEC has not removed the related disclosure from its regulations by June 30, 2027, the amendments will be removed from the Codification and not become effective. Early adoption is prohibited. The Company is currently evaluating the impact this update will have on its unaudited condensed consolidated financial statements and disclosures. Note 4 — Revenue from Contracts with Customers Revenue Recognized In the three and six month periods ended June 30, 2024, the Company recognized revenue of $ 976 and $ 1,977 , respectively, resulting from the delivery of patient EsoGuard test results. Revenue recognized from customer contracts deemed to include a variable consideration transaction price is limited to the unconstrained portion of the variable consideration.

As discussed in Note 10, Debt , the Company issued a Senior Secured Convertible Note dated March 21, 2023 with a $ 11.1 million face value principal (“March 2023 Senior Convertible Note”). The convertible note is accounted for under the ASC 825-10-15-4 fair value option (“FVO”) election, wherein, the financial instrument is initially measured at its issue date estimated fair value and subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. The estimated fair value of the financial instruments classified within the Level 3 category was determined using both observable inputs and unobservable inputs. Unrealized gains and losses associated with liabilities within the Level 3 category include changes in fair value attributable to both observable (e.g., changes in market interest rates) and unobservable (e.g., changes in unobservable long- dated volatilities) inputs. 1 There were no transfers between the respective Levels during the six months ended June 30, 2024. 14 Note 9 — Financial Instruments Fair Value Measurements - continued The estimated fair value of the March 2023 Senior Convertible Note as of each of June 30, 2024 and December 31, 2023 were computed using a Monte Carlo simulation of the present value of its cash flows using a synthetic credit rating analysis and a required rate-of-return, using the following assumptions: Schedule of Fair Value Assumption Used March 2023 Senior Convertible Note: June 30, 2024 March 2023 Senior Convertible Note: December 31, 2023 Fair Value $ 11,200 $ 13,950 Face value principal payable $ 9,811 $ 11,019 Required rate of return 10.00 % 10.00 % Conversion Price $ 5.00 $ 5.00 Value of common stock $ 0.82 $ 1.41 Expected term (years) 0.72 1.22 Volatility 60.00 % 60.00 % Risk free rate 5.09 % 4.56 % Dividend yield — % — % The estimated fair values reported utilized the Company’s common stock price along with certain Level 3 inputs (as discussed in the table above), in the development of Monte Carlo simulation models, discounted cash flow analyses, and /or Black-Scholes valuation models. The estimated fair values are subjective and are affected by changes in inputs to the valuation models and analyses, including the Company’s common stock price, the Company’s dividend yield, the risk-free rates based on U.S. Treasury security yields, and certain other Level-3 inputs including, assumptions regarding the estimated volatility in the value of the Company’s common stock price and the volatility of similar entities within the medical device industry. Changes in these assumptions can materially affect the estimated fair values.

The holders of Series B Preferred Stock will be entitled to dividends payable as follows: (i) a number of shares of Common Stock equal to 20% of the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock then held by such Holder on March 13, 2025, and (ii) a number of shares of Common Stock equal to 20% of the number of shares of Common Stock issuable upon conversion of the Series B Preferred Stock then held by such Holder on March 13, 2026. A holder that voluntarily converts its Series B Preferred Stock prior to March 13, 2025 or March 13, 2026, as the case may be, will not receive the dividend that accrues on such date with respect to such converted Series B Preferred Stock. The holders of the Series B Preferred Stock also will be entitled to dividends equal, on an as-if-converted to shares of Common Stock basis, to and in the same form as dividends actually paid on shares of the Common Stock when, as, and if such dividends are paid on shares of the Common Stock . In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company (or any Deemed Liquidation Event as defined in the Certificate of Designation), the holders of shares of Series B Preferred Stock then outstanding will be entitled to be paid out of the assets of the Company available for distribution to its stockholders, before any payment shall be made to the holders of Common Stock by reason of their ownership thereof, an amount per share equal to the greater of (i) the Stated Value, plus any dividends accrued but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series B Preferred Stock been converted into Common Stock immediately prior to such event. The Series B Preferred Stock is a voting security (subject to applicable ownership limitations). The Company will not effect any conversion of the Series B Preferred Stock, and a holder will not have the right to receive dividends or convert any portion of the Series B Preferred Stock, to the extent that, after giving effect to the receipt of dividends or the conversion, the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of the holder’s affiliates) would beneficially own in excess of 4.99% of the Company’s outstanding common stock (or, upon election of the holder, 9.99% of the Company’s outstanding common stock). The Company and the investors in the offering also executed a registration rights agreement (the “Series B Registration Rights Agreement”), pursuant to which the Company agreed to file a registration statement covering the resale of the shares of Common Stock issuable pursuant to the Series B Preferred Stock. The Company filed such registration statement on Form S-3 with the SEC (file number 333-280650), which filing became effective on July 18, 2024, covering the resale of the shares of Common Stock issuable pursuant to the Series B and Series B-1 Preferred Stock. 20 Note 12 — Stockholders’ Equity - continued Series B-1 Preferred Stock Offering On May 6, 2024, the Company issued approximately 11,634 shares of newly designated Series B-1 Convertible Preferred Stock (the “Series B-1 Preferred Stock”).

The aggregate gross proceeds from the sale of shares in such offering were $ 13.6 million. As noted above, on March 13, 2024, 100% of the then-outstanding shares of Series A Preferred Stock were exchanged for shares of Series B Preferred Stock in the Series B Preferred Stock Offering and Exchange.

An amendment effecting such change was filed with the Secretary of State of Delaware on July 23, 2024. Additionally and also subsequent to June 30, 2024, the Company’s shareholders approved, for purposes of Listing Rule 5635 of The Nasdaq Stock Market LLC (“Nasdaq”) the issuance of shares of the Company’s common stock under the Series B Convertible Preferred Stock (“Series B Preferred Stock”) sold by the Company in a private offering in March 2024 and the Series B-1 Convertible Preferred Stock (“Series B-1 Preferred Stock”) sold by the Company in a private offering in May 2024. Each of the Series B and Series B-1 Preferred Stock is a voting security. On any matter to be acted upon or considered by the stockholders of the Company, each holder shall be entitled to vote on an “as converted” basis after applying the beneficial ownership limitations described in the Series B and B-1 Preferred Stock Offering above. As of June 30, 2024 and December 31, 2023, there were 49,344,945 and 42,329,864 shares of common stock issued and outstanding, respectively. As of June 30, 2024, PAVmed holds 31,302,444 shares and maintains a controlling financial and voting interest in the Company.

The Company intends to consider all available options to regain compliance with the Nasdaq listing standards. Committed Equity Facility and ATM Facility On March 28, 2022, the Company entered into a committed equity facility with an affiliate of Cantor Fitzgerald (“Cantor”). Under the terms of the committed equity facility, Cantor has committed to purchase up to $ 50 million of the Company’s common stock from time to time at the request of the Company. While there are distinct differences, the facility is structured similarly to a traditional at-the-market equity facility, insofar as it allows the Company to raise primary equity capital on a periodic basis at prices based on the existing market price. Cumulatively a total of 680,263 shares of Lucid Diagnostics’ common stock were issued for net proceeds of approximately $ 1.8 million, after a 4 % discount, as of June 30, 2024. In November 2022, the Company entered into an “at-the-market offering” (“ATM”) for up to $ 6.5 million of its common stock that may be offered and sold under a Controlled Equity Offering Agreement between the Company and Cantor. Cumulatively a total of 230,068 shares of Lucid Diagnostics’ common stock were issued through the at-the-market equity facility for net proceeds of approximately $ 0.3 million, after payments of 3 % commissions, as of June 30, 2024. Note 13 — Net Loss Per Share The Net loss per share basic and diluted for the respective periods indicated is as follows: Schedule of Net Loss Per Share Basic and Diluted Three Months Ended June 30, Six Months Ended June 30, 2024 2023 2024 2023 Numerator Net loss $ ( 11,005 ) $ ( 11,381 ) $ ( 21,617 ) $ ( 27,628 ) Deemed dividend on Series A and Series A-1 Convertible Preferred Stock — — ( 7,496 ) — Net loss attributable to Lucid Diagnostics Inc. common stockholders $ ( 11,005 ) $ ( 11,381 ) $ ( 29,113 ) $ ( 27,628 ) Denominator Weighted average common shares outstanding, basic and diluted 48,212,040 41,833,823 46,613,362 41,404,547 Net loss per share (1) Net loss per share - basic and diluted $ ( 0.23 ) $ ( 0.27 ) $ ( 0.62 ) $ ( 0.67 ) (1) - Convertible Preferred Stock would potentially be considered a participating security under the two-class method of calculating net loss per share. However, the Company has incurred net losses to-date, and as such holders are not contractually obligated to share in the losses, there is no impact on the Company’s net loss per share calculation for the periods indicated. Basic weighted-average number of shares of common stock outstanding for the six month periods ended June 30, 2024 and 2023 include the shares of the Company issued and outstanding during such periods, each on a weighted average basis. The basic weighted average number of shares common stock outstanding excludes common stock equivalent incremental shares, while diluted weighted average number of shares outstanding includes such incremental shares. However, as the Company was in a loss position for all years presented, basic and diluted weighted average shares outstanding are the same, as the inclusion of the incremental shares would be anti-dilutive. The common stock equivalents excluded from the computation of diluted weighted average shares outstanding are as follows: Schedule of Common Stock Equivalents Excluded from Computation of Diluted Earnings Per Share June 30, 2024 2023 Stock options 8,744,626 4,949,962 Unvested restricted stock awards 3,897,440 1,872,100 Preferred stock 51,682,378 13,695,850 Total 64,324,444 20,517,912 22
