During the nine months ended September 30, 2024 and 2023, there were no transfers between Level 1, Level 2 and Level 3. The carrying values of other current liabilities approximate fair value in the accompanying condensed consolidated financial statements due to the short-term nature of those instruments.

Valuation of Convertible Note Receivable

The convertible note receivable was received in connection with the disposition of the UltraMIST/MIST business in 2020. At any time on or after January 1, 2021, at the sole discretion of the Company, amounts outstanding under the convertible note receivable (including accrued interest) may be converted into Sanuwave common stock at a defined rate. The convertible note receivable was to be paid on or before August 6, 2021.

On December 18, 2023, the Company entered into a forbearance agreement with Sanuwave (“Sanuwave Forbearance Agreement”). Per the Sanuwave Forbearance Agreement, from the period from December 18, 2023 to the earliest of (i) February 28, 2024, (ii) the commencement of bankruptcy proceedings for Sanuwave pursuant to the U.S. Bankruptcy Code, (iii) the occurrence of an event of default other than payment default, or (iv) the failure of Sanuwave to comply with any term, condition or covenant set forth in the forbearance agreement, the Company agrees that it will not exercise any remedy available to it under the convertible note receivable, excluding the right to increase the interest rate. As collateral for payments owed to Palantir Technologies, Inc. (“Palantir”), the Company assigned to Palantir the Sanuwave convertible note receivable in the event of default (see Note 9). On May 10, 2024, the Company entered into a letter agreement with Sanuwave to extend the forbearance period from February 28, 2024 to June 3, 2024. The letter agreement increased the total note payments to $2,175. Upon executing the letter agreement, Sanuwave made an initial note payment of $100 and on June 3, 2024, made a second note payment of $2,075, fully discharging all outstanding indebtedness under the note.

The following table presents a reconciliation of the convertible note receivable measured on a recurring basis using Level 3 inputs for the nine months ended September 30, 2024:

	Balance as of January 1, 2024		Net transfers in to (out of) Level 3		Purchases, settlements and other net			Fair value adjustments		Balance as of September 30, 2024
Assets:
Convertible note receivable	$	2,072	$	—	$	(2,072	)	$	—	$	—

At December 31, 2023, the fair value of this note was based on a bond valuation which employs a credit default model. The Company utilized Level 3 inputs on a probability weighted model based on outcomes of a default, repayment and conversion of the note. The measurement is based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions.

Significant inputs for the convertible note valuation model were as follows:

	December 31, 2023
Face value	$	4,000
Coupon rate		12% - 17%
Stock price	$	0.23
Term (years)		0.51-2.45
Risk-free interest rate		5.47	%
Volatility		n/a

Valuation of Contingent Consideration

The fair value measurement of the contingent consideration obligations is determined using Level 3 inputs and is based on a probability-weighted income approach. The measurement is based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions.

The following table presents a reconciliation of contingent consideration obligations measured on a recurring basis using Level 3 inputs for the nine months ended September 30, 2024:

	Balance as of January 1, 2024		Net transfers in to (out of) Level 3		Purchases, settlements and other net		Fair value adjustments		Balance as of September 30, 2024
Liabilities:
Acquisition-related contingent consideration obligations	$	1,606	$	—	$	—	$	—	$	1,606

The fair value of the liability to make potential future milestone and earn-out payments was estimated by the Company at each reporting date based, in part, on the results of a third-party valuation using a discounted cash flow analysis based on various assumptions, including the probability of achieving specified events, discount rates, and the period of time until earn-out payments are payable and the conditions triggering the milestone payments are met. The actual settlement of contingent consideration could differ from current estimates based on the actual occurrence of these specified events.

At each reporting date, the Company revalues the contingent consideration obligation to estimated fair value and records changes in fair value as income or expense in the Company’s condensed consolidated statements of operations and comprehensive loss. Changes in the fair value of the contingent consideration obligations may result from changes in discount periods and rates, changes in the timing and amount of revenue estimates and changes in probability assumptions with respect to the likelihood of achieving the various contingent consideration obligations. The change in the fair value of the contingent consideration obligations during the nine months ended September 30, 2024 was de minimus. The Company has classified all of the contingent consideration as a long-term liability in the condensed consolidated balance sheets as of September 30, 2024 and December 31, 2023. See Note 9 for more information on contingent consideration.

Valuation of Contingent Stock Consideration

The contingent stock consideration liability at September 30, 2024, is comprised of the fair value of potential future issuance of Class A common stock to CariCord participating shareholders pursuant to a settlement agreement signed during the year ended December 31, 2021. The fair value measurement of the contingent stock consideration obligation is determined using Level 3 inputs and is based on a probability weighted expected return methodology (“PWERM”). The measurement is largely based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions.

The following table presents a reconciliation of the contingent stock consideration obligation measured on a recurring basis using Level 3 inputs for the nine months ended September 30, 2024:

	Balance as of January 1, 2024		Net transfers in to (out of) Level 3		Purchases, settlements and other net		Fair value adjustments		Balance as of September 30, 2024
Liabilities:
Contingent stock consideration	$	27	$	—	$	—	$	—	$	27

The fair value of the liability to issue future shares of Class A common stock was estimated by the Company at each reporting date using a PWERM based on various inputs and assumptions, including the Company’s common share price, discount rates, and the probability of achieving specified future operational targets. The actual settlement of contingent stock consideration could differ from current estimates based on the actual achievement of these specified targets and movements in the Company’s common share price.

At each reporting date, the Company revalues the contingent stock consideration obligation to estimated fair value and records changes in fair value as income or expense in the Company’s condensed consolidated statements of operations and comprehensive loss. Changes in the fair value of the contingent stock consideration obligation may result from changes in discount rates, changes in the Company’s common share price, and changes in probability assumptions with respect to the likelihood of achieving specified operational targets. The change in the fair value of the contingent stock consideration obligation during the nine months ended September 30, 2024 was de minimus. The Company has classified all of the contingent stock consideration as a current liability in the condensed consolidated balance sheets as of September 30, 2024 and December 31, 2023.

Valuation of Short-Term Debt - Yorkville

The Company elected the fair value option to account for the Yorkville PPA signed on September 15, 2022 (see Note 7). As of December 31, 2023, due to the short-term nature of the debt, the fair value of the Yorkville PPA approximated the settlement amount, which was fully paid on January 17, 2024. The Company also elected the fair value option to account for the Yorkville convertible promissory note signed on March 13, 2024 (see Note 7). The fair value measurement of the debt is determined using Level 3 inputs and assumptions unobservable in the market. Changes in the fair value of debt that is accounted for at fair value, inclusive of related accrued interest expense, are presented as gains or losses in the accompanying condensed consolidated statements of operations and comprehensive loss under change in fair value of debt. The portion of total changes in fair value of debt attributable to changes in instrument-specific credit risk are determined through specific measurement of periodic changes in the discount rate assumption exclusive of base market changes and are presented as a component of comprehensive loss in the accompanying condensed consolidated statements of operations and comprehensive loss. The actual settlement of the short-term debt could differ from current estimates based on the timing of when and if Yorkville elects to convert amounts into common shares, potential cash repayment by the Company prior to maturity, and movements in the Company’s common share price.

The following table presents a reconciliation of short-term debt obligations measured on a recurring basis using Level 3 inputs for the nine months ended September 30, 2024:

Liabilities:
Balance as of January 1, 2024	$	17,223
Principal repayments		(17,374	)
Issuance of convertible promissory note		3,150
Fair value adjustment through earnings		694
Fair value adjustment through accumulated other comprehensive income		2
Balance as of September 30, 2024	$	3,695

The fair value of the Yorkville convertible promissory note is based on a valuation which employs a Monte Carlo model and a credit default model. The Company utilized Level 3 inputs in a probability weighted model based on outcomes of a default, repayment and conversion of the note. The measurement is based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions. The fair value of the Yorkville convertible promissory note on March 13, 2024, the date of issuance, was $2,993.

Significant inputs for the Yorkville convertible promissory note valuation model were as follows:

	September 30, 2024			March 13, 2024
				(issuance)
Common share price	$	2.97		$	5.79
Credit spread		8.00	%		8.50	%
Dividend yield		0	%		0	%
Term (years)		0.45			1.00
Risk-free interest rate		4.30	%		4.90	%
Volatility		50.0	%		50.0	%

Valuation of Warrant Liability

The warrant liability at September 30, 2024 is comprised of the fair value of warrants to purchase shares of Class A common stock. The Public Warrants are recorded at fair value based on the period-end publicly stated close price, which is a Level 1 input. The January 2024 Bridge Loan - Tranche #2 Warrants were recorded at fair value based on a Monte Carlo simulation model and the Registered Direct, PIPE and Sponsor Warrants are recorded at their respective closing date fair values based on a Black-Scholes option pricing model that utilizes inputs for: (i) value of the underlying asset, (ii) the exercise price, (iii) the risk-free rate, (iv) the volatility of the underlying asset, (v) the dividend yield of the underlying asset and (vi) maturity, which are Level 3 inputs. The Black-Scholes option pricing model’s primary unobservable input utilized in determining the fair values of the warrant liabilities is the expected volatility of the Class A common stock. Prior to the merger, Legacy Celularity was a private company and lacked company-specific historical and implied volatility information for its stock. Therefore, the Company estimates its expected stock price volatility using its volatility since the merger and the historical volatility of publicly traded peer companies. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the estimated remaining term of the warrants. Inputs to the Monte Carlo and Black-Scholes option pricing models for the warrants are updated each reporting period to reflect fair value.

The following table presents a reconciliation of the warrant liabilities measured on a recurring basis using Level 3 inputs for the nine months ended September 30, 2024:

Balance as of January 1, 2024	$	3,784
January 2024 Bridge Loan - Tranche #2 warrant issuance		1,858
Gain recognized in earnings from change in fair value		1,587
Reclassification of warrants from liability classified to equity classified		(2,970	)
Balance as of September 30, 2024	$	4,259

Significant inputs for the May 2022 PIPE Warrants and the 2023 Registered Direct Warrants were as follows:

	September 30, 2024			December 31, 2023
Common share price	$	2.97		$	2.47
Exercise price	$	3.50 - 7.50		$	3.50 - 7.50
Dividend yield		0	%		0	%
Term (years)		4.03 - 4.34			4.78 - 5.09
Risk-free interest rate		3.58	%		3.84	%
Volatility		97.1% - 98.1	%		100.1% - 100.7	%

Significant inputs for the January 2024 Bridge Loan - Tranche #2 Warrants were as follows:

	July 15, 2024			January 16, 2024
	(reclassification)			(issuance)
Common share price	$	3.19		$	2.00
Term to initial exercise date (years)(1)		N/A			0.50
Dividend yield		0	%		0	%
Term (years)		5.0			5.0
Risk-free interest rate		4.00	%		3.90	%
Volatility		112.5	%		107.5	%

(1) As discussed further in Note 7, the warrants were not exercisable and the exercise price was not set until certain conditions were met. As of July 15, 2024, the warrants became exercisable and no longer contain adjustment provisions to the exercise price that are not indexed to the Company’s own stock. As such, the warrants were marked to fair value as of the initial exercise date and then reclassified from liability classified to equity classified.

Significant inputs for the Sponsor Warrants were as follows:

	September 30, 2024			December 31, 2023
Common share price	$	2.97		$	2.47
Exercise price	$	115.00		$	115.00
Dividend yield		0	%		0	%
Term (years)		1.8			2.5
Risk-free interest rate		3.66	%		4.12	%
Volatility		105.9	%		100.7	%

	$	1,006	$	—	$	146,326	$	147,332

During the years ended December 31, 2023 and 2022, there were no transfers between Level 1, Level 2 and Level 3.

The Company’s cash equivalents consisted of a money market funds. The money market fund was valued using inputs observable in active markets for similar securities, which represents a Level 1 measurement in the fair value hierarchy. The carrying values of accounts receivable, accounts payable, deferred revenue and other current liabilities approximate fair value in the accompanying consolidated financial statements due to the short-term nature of those instruments.

Valuation of Contingent Consideration

The fair value measurement of the contingent consideration obligations is determined using Level 3 inputs and is based on a probability-weighted income approach. The measurement is based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions.

The following table presents a reconciliation of contingent consideration obligations measured on a recurring basis using Level 3 inputs as of December 31, 2023 and 2022:

	Balance as of December 31, 2022		Net transfers in to (out of) Level 3		Purchases, settlements and other net		Fair value adjustments			Balance as of December 31, 2023
Liabilities:
Acquisition-related contingent consideration obligations	$	105,945	$	—	$	—	$	(104,339	)	$	1,606

	Balance as of December 31, 2021		Net transfers in to (out of) Level 3		Purchases, settlements and other net		Fair value adjustments			Balance as of December 31, 2022
Liabilities:
Acquisition-related contingent consideration obligations	$	232,222	$	—	$	—	$	(126,277	)	$	105,945

The fair value of the liability to make potential future milestone and earn-out payments was estimated by the Company at each reporting date based, in part, on the results of a third-party valuation using a discounted cash flow analysis based on various assumptions, including the probability of achieving specified events, discount rates, and the period of time until earn-out payments are payable and the conditions triggering the milestone payments are met. The actual settlement of contingent consideration could differ from current estimates based on the actual occurrence of these specified events.

At each reporting date, the Company revalues the contingent consideration obligation to estimated fair value and records changes in fair value as income or expense in the Company’s consolidated statements of operations. Changes in the fair value of the contingent consideration obligations may result from changes in discount periods and rates, changes in the timing and amount of revenue estimates and changes in probability assumptions with respect to the likelihood of achieving the various contingent consideration obligations. The Company has classified all of the contingent consideration as a long-term liability in the consolidated balance sheets as of December 31, 2023 and 2022. See Note 11, “Commitment and Contingencies”, for more information on contingent consideration.

Valuation of Warrant Liability

The warrant liability at December 31, 2023 is composed of the fair value of warrants to purchase shares of Class A Common Stock. The Liability Warrants were recorded at their respective closing date fair values based on a Black-Scholes option pricing model that utilizes inputs for: (i) value of the underlying asset, (ii) the exercise price, (iii) the risk-free rate, (iv) the volatility of the underlying asset, (v) the dividend yield of the underlying asset and (vi) maturity. The Black-Scholes option pricing model’s primary unobservable input utilized in determining the fair value of the Liability Warrants is the expected volatility of the Class A Common Stock. Prior to the Mergers, Legacy Celularity was historically a private company and lacks company-specific historical and implied volatility information for its stock. Therefore, it estimates its expected stock price volatility based on the historical volatility of publicly traded peer companies. Inputs to the Black-Scholes option pricing model for the warrants are updated each reporting period to reflect fair value. The public warrants (the “Public Warrants”) were recorded at the closing date fair value based on the close price of such warrants. Each subsequent reporting period, the Public Warrants are marked-to-market based on the period-end close price.

As of December 31, 2023 and 2022, the fair value of the warrant liabilities was $4,359 and $3,598, respectively. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve for time periods approximately equal to the estimated remaining term of the warrants.

The following table provides a roll-forward of the aggregate fair values of the Company’s warrant liabilities for which fair values are determined using Level 3 inputs:

Valuation of the Note Receivable

The convertible note receivable was received in connection with the disposition of the UltraMIST/MIST business in 2020. At any time on or after January 1, 2021, at the sole discretion of the Company, amounts outstanding under the convertible note receivable (including accrued interest) may be converted into Sanuwave common stock at a defined rate. The convertible promissory note was to be paid on or before August 6, 2021, however, remains outstanding in full as of December 31, 2023 and 2022. The fair value of this note was based on a bond valuation which employs a credit default model. The Company utilized Level 3 inputs on a probability weighted model based on outcomes of a default, repayment and conversion of the note. The measurement is based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions.

Significant inputs for the convertible note valuation model are as follows:

	December 31, 2023			December 31, 2022
Face value	$	4,000		$	4,000
Coupon rate		12% - 17%			12% - 17%

Volatility		n/a			n/a

On December 18, 2023, the Company entered into a forbearance agreement with Sanuwave (“Sanuwave Forbearance Agreement”). Per the agreement, from the period from December 18, 2023 to the earliest of (i) February 28, 2024, (ii) the commencement of bankruptcy proceeds for Sanuwave pursuant to the U.S. Bankruptcy Code, (iii) the occurrence of an event of default other than payment default, (iv) the failure of Sanuwave to comply with any term, condition or covenant set forth in the agreement, the Company agrees that it will not, exercise any remedy available to it under the Convertible Note Receivable, excluding the right to increase the interest rate. As collateral for payments owed to Palantir, the Company assigned the Sanuwave convertible note in the event of default (see Note 11). On May 10, 2024, the Company entered into a letter agreement with Sanuwave to extend the forbearance period from February 28, 2024 to June 3, 2024. The letter agreement increased the total note payments to $2,175. Upon executing the letter agreement, Sanuwave made an initial note payment of $100 and on June 3, 2024 made a second note payment of $2,075 fully discharging all outstanding indebtedness under the note.

Valuation of the Contingent Stock Consideration

The contingent stock consideration liability at December 31, 2023, is comprised of the fair value of potential future issuance of Class A Common Stock to CariCord participating shareholders pursuant to a settlement agreement signed during the year ended December 31, 2021 (see Note 11). The fair value measurement of the contingent stock consideration obligation is determined using Level 3 inputs and is based on a probability-weighted expected return methodology (“PWERM”). The measurement is largely based upon unobservable inputs supported by little or no market activity based on the Company’s own assumptions. As of December 31, 2021, the applicable procurement targets were not probable of being achieved.

The following table presents a reconciliation of the contingent stock consideration obligation measured on a recurring basis using Level 3 inputs as of December 31, 2023 and 2022:

	Balance as of December 31, 2022		Net transfers in to (out of) Level 3		Purchases, settlements and other net		Fair value adjustments			Balance as of December 31, 2023
Liabilities:
Contingent stock consideration	$	186	$	—	$	—	$	(159	)	$	27

The fair value of the liability to issue future shares of Class A Common Stock was estimated by the Company at each reporting date using a PWERM based on various inputs and assumptions, including the Company’s common share price, discount rates, and the probability of achieving specified future operational targets. The actual settlement of contingent stock consideration could differ from current estimates based on the actual achievement of these specified targets and movements in the Company’s common share price.

At each reporting date, the Company revalues the contingent stock consideration obligation to estimated fair value and records changes in fair value as income or expense in the Company’s consolidated statements of operations. Changes in the fair value of the contingent stock consideration obligation may result from changes in discount rates, changes in the Company’s common share price, and changes in probability assumptions with respect to the likelihood of achieving specified operational targets. The Company has classified all of the contingent stock consideration within accrued expenses and other current liabilities in the consolidated balance sheets as of December 31, 2023. See Note 11, “Commitments and Contingencies”, for more information on contingent stock consideration.

Valuation of Short-Term Debt - Yorkville

The Company elected the fair value option to account for the financial instrument with Yorkville signed on September 15, 2022 (see Note 9). As of December 31, 2023, due to the short term nature of the debt, the fair value approximates the settlement amount which was fully paid on January 17, 2024. As of December 31, 2022, the estimate of the fair value was determined using a binomial lattice model. The fair value measurement of the debt is determined using Level 3 inputs and assumptions unobservable in the market. Changes in the fair value of debt that is accounted for at fair value, inclusive of related accrued interest expense, are presented as gains or losses in the accompanying consolidated statements of operations and comprehensive income (loss) under change in fair value of debt. The portion of total changes in fair value of debt attributable to changes in instrument-specific credit risk are determined through specific measurement of periodic changes in the discount rate assumption exclusive of base market changes and are presented as a component of comprehensive income (loss) in the accompanying consolidated statements of operations and comprehensive income (loss). The actual settlement of the short-term debt could differ from current estimates based on the timing of when and if Yorkville elects to convert amounts into common shares, potential cash repayment by the Company prior to maturity, and movements in the Company’s common share price.

The following table presents a reconciliation of the Yorkville debt measured on a recurring basis using Level 3 inputs as of the initial valuation date of September 15, 2022 and as of December 31, 2023:
