Jaguar Health, Inc. Fair Value Disclosure

3. Fair Value Measurements

ASC 820 defines fair value, establishes a framework for measuring fair value under US GAAP and enhances disclosures about fair value measurements. Fair value is defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value under ASC 820 must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

The fair value of the Streeterville Note recognized as a Level 3 liability at the date of issuance and as of December 31, 2025 amounted to $7.8 million and $8.2 million, respectively. The fair value of the remaining Level 3 liabilities at the extinguishment date and as of December 31, 2025 amounted to $23.7 million and $23.5 million. The fair values were based on the weighted average discounted expected future cash flows representing the terms of the notes, discounting them to their present value equivalents. The notes were classified as Level 3 fair values in the fair value hierarchy due to the use of unobservable inputs, including the Company’s own credit risk.

The Company determined and performed the valuations with the assistance of an independent valuation service provider. On a quarterly basis, the Company considers the main Level 3 inputs for hybrid instruments used derived as follows:

The fair value of the Convertible Notes recognized as a Level 3 liability at the date of issuance and as of December 31, 2025, amounted to $2.5 million. The fair value was determined based on the discounted expected future cash flows representing the terms of the notes, including their short-term maturity and conversion features, and was discounted to present value equivalents. The notes were classified as Level 3 within the fair value hierarchy due to the use of unobservable inputs, including the Company’s own credit risk.

The Company determined and performed the valuation with the assistance of an independent valuation service provider. On a quarterly basis, the Company considers the main Level 3 input for these freestanding financial instruments to be the discount rate, which was determined using a comparison of various effective yields on bonds as of the valuation date.

For the additional notes designated at FVO that are freestanding, the Company considers only the discount rate which was determined using a comparison of various effective yields on bonds as of valuation date.

The fair value of the derivative asset recognized as a Level 3 liability at the date of issuance and as of December 31, 2025, amounted to $322,000. The fair value was determined using a Black-Derman-Toy ("BDT") binomial lattice model in conjunction with a discounted cash flow methodology. The valuation incorporates a discount rate derived from the risk-free rate, based on the US Treasury Daily Treasury Par Yield Curve, plus a weighted option-adjusted spread ("OAS"). The weighted OAS reflects a blended credit profile of the Company and the financial institution holding the related collateral.

Fair Value Option

The Company elected to apply the FVO accounting to certain freestanding instruments and to the entire class of hybrid instruments, including structured notes, of which there are assessed embedded derivatives that would be eligible for bifurcation, to align the measurement attributes of those instruments under US GAAP and to simplify the accounting model applied to these financial instruments.

The valuations of these instruments were predominantly driven by the discount rate and the derivative features embedded within the instruments. The Company determined and performed the valuations of the freestanding and hybrid instruments with the assistance of an independent valuation service provider. The valuation methodology utilized is consistent with the income approach for estimating the fair value of the interest-bearing portion of the instruments and the related derivatives. Cash flows of the financial instruments in their entirety, including the embedded derivatives, are discounted at an appropriate rate for the applicable duration of the instrument. Interests on the interest-bearing portion of the instruments held to maturity and mark-to-market adjustments are aggregated in the changes in fair value of freestanding and hybrid financial instruments designated at FVO in the consolidated statements of operations. For the year ended December 31, 2025 and 2024, the Company did not note any fair value movement on FVO liabilities attributable to any instrument-specific credit risk, which should be recorded in other comprehensive income (loss).
