Fair Value of Financial Instruments

11. Fair Value of Financial Instruments

The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. The Company uses the exit price method for estimating the fair value of loans for disclosure purposes. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy are described in Note 1 – Description of Business and Significant Accounting Policies.

The carrying amounts reported in the condensed consolidated financial statements for cash, accounts receivable, accounts payable, and accrued expenses and other current liabilities (excluding the Milestone Rights liability) approximate their fair value due to their relatively short maturities. The carrying value of the Company's Blackstone term loans approximates fair value because the loans bear interest at variable rates that are reflective of current market conditions. The fair value of the senior convertible notes, Milestone Rights liability, Financing liability, Liability for sale of future royalties and Contingent consideration liability are disclosed below.

Financial Liabilities — The following tables set forth the fair value of the Company’s financial instruments (Level 3 in the fair value hierarchy) (in millions):

Fair value was determined by applying a Monte Carlo simulation method for the calculation of the potential payment and the Geometric Brownian Motion forecasting model to estimate the underlying revenue. Market based inputs and other Level 3 inputs were used to forecast future revenue. The key inputs used included a risk-free rate of 4.27%, dividend yield of 0%, volatility of 43.0%, period of 7 years and credit risk of 12.5%.
(2)
Fair value was determined by applying a discounted cash flow analysis with a hypothetical yield of 9.5%. A change in yield of + or – 2% would result in a fair value of $93.0 million and $118.1 million, respectively.
(3)
Fair value was determined by applying a discounted cash flow analysis with a hypothetical yield of 10.5%. A change in yield of + or – 2% would result in a fair value of $85.1 million and $101.5 million, respectively.
(4)
Fair value was determined to be $28.9 million for Milestone 1 using a probability weighted expected return methodology based on the Company's estimate of probability of achievement of regulatory approval which was 95% across various timepoints and a discount rate of 11.7%. A change in estimate of probability and discount rate for Milestone 1 of + or – 2% would result in a fair value of $28.0 million and $29.8 million, respectively. Fair value was determined to be $5.1 million for Milestone 2 using a Monte Carlo simulation method based on a 56.7% volatility and 11.7% discount rate. Market based inputs and other Level 3 inputs were used to forecast future revenue. A change in discount rate on Milestone 2 of + or – 2% would result in a fair value of $5.1 million and $5.2 million, respectively.

Fair value was determined by applying a discounted cash flow analysis to the straight note with a hypothetical yield of 5.0%, volatility of 40.3% and a Monte Carlo simulation for the value of the conversion feature. A change in yield of + or – 2% would result in a fair value of $39.0 million and $39.5 million, respectively.

Fair value was determined by applying a Monte Carlo simulation method for the calculation of the potential payment and the Geometric Brownian Motion forecasting model to estimate the underlying revenue. Market based inputs and other Level 3 inputs were used to forecast future revenue. The key inputs used included a risk-free rate of 3.94%, dividend yield of 0%, volatility of 43.0%, period of 7 years and credit risk of 10%.
(3)
Fair value was determined by applying a discounted cash flow analysis with a hypothetical yield of 7.0%. A change in yield of + or – 2% would result in a fair value of $106.7 million and $140.6 million, respectively.
(4)
Fair value was determined by applying a discounted cash flow analysis with a hypothetical yield of 8.0%. A change in yield of + or – 2% would result in a fair value of $148.3 million and $192.3 million, respectively.
(5)
Fair value was determined to be $23.7 million for Milestone 1 using a probability weighted expected return methodology based on the Company's estimate of probability of achievement of regulatory approval which was 85% across various timepoints and a discount rate of 10%. A change in estimate of probability and discount rate for Milestone 1 of + or – 2% would result in a fair value of $24.7 million and $22.7 million, respectively. Fair value was determined to be $2.6 million for Milestone 2 using a Monte Carlo simulation method based on a 25.2% volatility and 10% discount rate. Market based inputs and other Level 3 inputs were used to forecast future revenue. A change in discount rate on Milestone 2 of + or – 2% would result in a fair value of $2.6 million and $2.7 million, respectively.

Milestone Rights Liability — The fair value measurement of the Milestone Rights liability is sensitive to the discount rate and the timing of achievement of milestones. The Company utilized a Monte-Carlo Simulation Method to simulate the Afrezza net sales under a neutral framework to estimate the potential payments and the Geometric Brownian Motion forecasting model to estimate the underlying revenue. The Company then discounted the future expected payments at cost of debt with a term equal to the simulated time to payout based on cumulative sales. See Note 15 – Commitments and Contingencies.

Financing Liability — The Sale-Leaseback Transaction in November 2021 resulted in a financing liability. See Note 15 – Commitments and Contingencies.

Liability for Sale of Future Royalties — The sale of a portion of our royalty rights in December 2023 resulted in a liability for sale of future royalties. See Note 15 – Commitments and Contingencies.

Contingent Consideration Liability — The acquisition of scPharma in October 2025 resulted in a contingent consideration liability. See Note 2 – Business Combinations.
