Fair Value Measurement | Note 3 — Fair Value Measurement Assets and liabilities recorded at fair value on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at 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 authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. As of March 31, 2025 and December 31, 2024, the Company had no financial assets measured at fair value on a recurring basis. As of March 31, 2025, the Company’s financial liabilities measured at fair value on a recurring basis, were as follows (in thousands):
The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial instruments for the three months ended March 31, 2025 and 2024 (in thousands):
The Company elected to measure its Tasly convertible debt at fair value (Note 5) with changes in fair value reported in earnings as they occur. The Convertible Debt fair values were determined using the discounted cash flow methodology based on probability weighted scenarios of the convertible notes conversion. At issuance of the first $1 million on June 26, 2023 the time to event was .28 years and the discount rate applied was 14.54%. At issuance of the next $0.3 million on July 20, 2023, the time to event was .22 years and the discount rate applied was 13.82%. At issuance of the additional $0.3 million on August 15, 2023, the time to event was .15 years and the discount rate applied was 13.70%. The final amount which was less than $0.02 million was issued on February 6, 2024; the time to event was .66 years and the discount rate applied was 13.69%. On March 31, 2025, the time event was .25 years and the discount rate applied was 13.21%. Based on this method, the fair value of the convertible debt at the date of inception was $1,616,490, and the fair value at March 31, 2025 was $2,010,545. |

Fair Value Measurement | Note 8 — Fair Value Measurements Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The Company’s financial instruments are classified as either Level 1, Level 2 or Level 3. These tiers include: • Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets; • Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and • Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The following tables present information about the Company’s assets and liabilities that are measured at fair value on March 31, 2025 and December 31, 2024, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:
The Public Warrants, the Private Placement Warrants and the Representative’s Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented within liabilities on the condensed consolidated balance sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the condensed consolidated statements of operations. The Company utilized a Monte Carlo simulation model for the initial valuation of the Public Warrants. The subsequent measurement of the Public Warrants at March 31, 2025 and December 31, 2024 was classified as Level 2 due to the lack of an active market. As of March 31, 2025 and December 31, 2024, the aggregate value of Public Warrants was $569,250 and $379,500, respectively. The Company uses a Monte Carlo simulation model to value the Private Placement Warrants and the Representative’s Warrants. The Private Placement Warrants and the Representative’s Warrants were classified within Level 3 of the fair value hierarchy due to the use of unobservable inputs. Inherent in pricing models are assumptions related to expected share-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The key inputs into the Monte Carlo simulation model for the warrant liabilities were as follows at March 31, 2025 and December 31, 2024:
The key inputs into the Monte Carlo simulation model for the convertible promissory note were as follows at March 31, 2025 and December 31, 2024:
The key inputs into the Monte Carlo simulation model for the securities purchase agreement were as follows at March 31, 2025 and December 31, 2024:
The following table provides a summary of the changes in the fair value of the Company’s Level 3 financial instruments that are measured at fair value on a recurring basis for the three months ended March 31, 2025 and 2024:
The fair value of the Company’s convertible promissory note is valued using a compound option formula on the convertible feature and a present value of the host contract. The valuation technique requires inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumption about the assumptions a market participant would use in pricing the working capital loan. The convertible promissory note was classified within Level 3 of the fair value hierarchy due to the use of unobservable inputs. Inherent in pricing models are assumptions related to expected share-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of its common stock based on historical volatility that matches the expected remaining life of the note. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the note. The expected life of the note is assumed to be equivalent to their remaining contractual term.
The Company utilizes a Monte Carlo model to estimate the fair value of the conversion feature within the securities purchase agreement, which is required to be recorded at its initial fair value on the date of issuance, and each balance sheet date thereafter. Changes in the estimated fair value of the conversion feature are recognized as non-cash gains or losses in the accompanying condensed consolidated statements of operations. The key assumptions in the model relate to expected share-price volatility, risk-free interest rate, exercise price, expected term and the probability of occurrence of the transaction. The expected volatility was based on the average volatility of special purpose acquisition companies that are searching for an acquisition target. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the note. The expected life of the note is assumed to be equivalent to their remaining contractual term. |
