Datavault AI Inc. Fair Value Disclosure
6. | Fair Value Measurements |
The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. Each level of input has different levels of subjectivity and difficulty involved in determining fair value.
| ● | Level 1 – Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Therefore, determining fair value for Level 1 investments generally does not require significant judgment, and the estimation is not difficult. |
| ● | Level 2 – Pricing is provided by third-party sources of market information obtained through investment advisors. The Company does not adjust for or apply any additional assumptions or estimates to the pricing information received from its advisors. |
| ● | Level 3 – Inputs used to measure fair value are unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 instruments involves the most management judgment and subjectivity. |
The Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2025 and 2024 by level within the fair value hierarchy, are as follows:

The Company’s DV Note equaled its cash payoff value as of December 31, 2025 as the balance was paid off in cash in January 2026.
There were no transfers between Level 1, 2 or 3 during the years ended December 31, 2025 or 2024.
Warrant Liabilities
On March 26, 2024, the Company amended the terms of certain warrant agreements to remove certain exercise price reset, right to reprice and/or share adjustment provisions (“Reset Provisions”) following a reverse split, in addition to other revisions to the warrants. In April 2024, the Company effected the April 2024 Reverse Stock Split thereby removing the Reset Provisions (“Reset Amendment Effective Date”) and in accordance with provisions in certain of the warrants issued warrants to purchase an additional 5,602,693 shares of common stock. Accordingly, the Company remeasured the warrant liability for each of the amended warrants following the Reset Amendment Effective Date and recorded that amount to change in fair value of warrant liabilities with a corresponding increase to warrant liabilities. Following the Reset Amendment Effective Date, such warrants were no longer deemed to be liability warrants but were now classified as equity warrants. In connection with this reclassification, the Company reclassed approximately $41.9 million from warrant liabilities to additional paid in capital.
The following table includes a summary of changes in fair value of the Company’s warrant liabilities measured at fair value using significant unobservable inputs (Level 3) as of December 31, 2025 and 2024. For December 31, 2025, we do not consider the fair value of the warrants to be material to the financial statements. For December 31, 2024, the fair value of the common warrants was determined using the Black-Scholes Model based on the following key inputs and assumptions: common stock price of $2.05; exercise price of $1.83 to $1,574; expected yield of 0.0%; expected volatility of 162.8% to 185.0%; risk-free interest rate of 4.1% to 4.3% and expected life of 2.9 to 4.4 years.

About Fair Value Disclosures
Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.
Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
