Note 1 — The Company Description of the Business Lucid Diagnostics Inc. is a commercial-stage, cancer prevention medical diagnostics company. Lucid is focused on the millions of patients with gastroesophageal reflux disease (GERD), also known as chronic heartburn, who are at risk of developing esophageal precancer and cancer. 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 an FDA 510(k) cleared and CE Mark certified noninvasive swallowable balloon capsule catheter device designed for in-office targeted sampling of surface esophageal cells in a less than two minute long office procedure. It consists of a vitamin sized semi-rigid plastic capsule tethered to a thin silicone catheter from which a soft inflatable silicone balloon with textured ridges emerges to gently swab surface esophageal cells. When 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. 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 $ 1.2 million and $ 3.2 million of revenue for the three and nine months ended September 30, 2025, respectively, however the Company expects to continue to experience recurring losses and to generate negative cash flows from operating activities in the near future. The Company incurred a net loss attributable to its common stockholders of approximately $ 54.3 million and had net cash flows used in operating activities of approximately $ 33.9 million for the nine months ended September 30, 2025. As of September 30, 2025, the Company had working capital of approximately $ 23.6 million, with such working capital inclusive of the 2024 Convertible Notes (as defined below) classified as a current liability of approximately $ 22.3 million and approximately $ 47.3 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, and increasing revenue through cash pay and contracted revenue programs that target, among others, concierge medicine practices and 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. 6 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, 2024 as filed with the SEC on March 24, 2025, 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 non-consolidated subsidiary of PAVmed, which has the ability to exercise significant influence over 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, 2024 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 nine months ended September 30, 2025 are not necessarily indicative of the consolidated results to be expected for the year ending December 31, 2025 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, 2024 included in the Company’s Annual Report on Form 10-K as filed with the SEC on March 24, 2025. 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. 7 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. 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 November 12, 2024, the Company issued Senior Secured Convertible Notes dated November 22, 2024, referred to herein as the “2024 Convertible Notes”, which are 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 2024 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 2024 Convertible Notes). See Note 9, Financial Instruments Fair Value Measurements , with respect to the FVO election; and Note 10, Debt , for a discussion of the 2024 Convertible Notes. 8 Note 3 — Summary of Significant Accounting Policies - continued Recently Adopted Accounting Pronouncements 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 guidance was adopted by the Company effective January 1, 2025, on a prospective basis. The Company does not expect the standard to have a significant impact on its consolidated financial statements in the 2025 Annual Report on Form 10-K. Recent Accounting Standards Updates Not Yet Adopted In November 2024, the FASB issued ASU No. 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This update enhances financial statement disclosures by requiring public business entities to disclose specified information about certain costs and expenses including the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, and (d) intangible asset amortization included in each relevant expense caption. The update also requires disclosure of certain amounts that are already required to be disclosed under current GAAP, disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this update may be applied either prospectively or retrospectively and are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the potential impact of this guidance on its unaudited condensed consolidated financial statements.

The convertible notes are accounted for under the fair value option (“FVO”) election, wherein, the financial instruments are initially measured at their 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. The estimated fair value of the 2024 Convertible Notes as of each September 30, 2025 and December 31, 2024 was 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 2024 Convertible Notes: September 30, 2025 2024 Convertible Notes: December 31, 2024 Fair Value $ 22,300 $ 18,600 Face value principal payable $ 21,975 $ 21,975 Required rate of return 28.70 % 29.00 % Conversion Price $ 1.00 $ 1.00 Value of common stock $ 1.01 $ 0.819 Expected term (years) 4.15 4.90 Volatility 40.00 % 40.00 % Risk free rate 3.62 % 4.28 % 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.

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 nine months ended September 30, 2025 and 2024 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 of common stock outstanding excludes common stock equivalent incremental shares, while diluted weighted average number of shares of common stock outstanding includes such incremental shares. However, as the Company was in a loss position for all periods 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 September 30, 2025 2024 Stock options 9,927,410 8,662,549 Unvested restricted stock awards 6,584,240 3,897,440 Preferred stock 49,490,593 51,682,378 Total 66,002,243 64,242,367 Note 14 — Segment Information Lucid’s Chief Executive Officer is the Chief Operating Decision Maker (“CODM”).
