For purposes of calculating the average amounts in each applicable year, the names of each of the Non-PEO NEOs included are as follows: (a) for 2025: Patrick Fleury, Kerri Langlais, Nazar Khan, Kenneth Deane and William Tanimoto; (b) for 2024: Patrick Fleury, Kerri Langlais, Nazar Khan and Kenneth Deane; (b) for 2023: Patrick Fleury and Kerri Langlais; (c) for 2022: Patrick Fleury and Kenneth Deane; and (d) for 2021: Nazar Khan, Kerri Langlais, Claude Piguet and Kenneth Hegman.

Adjustment To PEO Compensation, Footnote The dollar amounts reported in this column represent the amount of “compensation actually paid” to our PEO for the applicable fiscal year, as computed in accordance with Item 402(v) of Regulation S-K, which for 2025, 2024, 2023 and 2022, includes our current PEO Paul Prager, and for 2021, includes our current PEO Paul Prager and former PEO Glenn Sandgren (PEO 2). The dollar amounts do not reflect the actual amount of compensation earned by or paid to such executives during the applicable year. No adjustments were made to Mr. Prager’s compensation reported in the “Total” column of the Summary Compensation Table as no equity compensation was granted to or outstanding for Mr. Prager during 2023, 2022 and 2021. No adjustments were made to Mr. Sandgren’s compensation reported in the “Total” column of the Summary Compensation Table for the fair value at year-end of his outstanding and unvested equity awards granted in 2021 as such awards were canceled and settled/exercised in connection with the Company’s completion of its business combination, including the related mergers, with IKONICS on December 13, 2021 and, as a result, such values were already included in Mr. Sandgren’s compensation reported in the “All Other Compensation” and “Total” columns of the Summary Compensation Table for the fiscal year 2021 as disclosed in the Company’s 2022 proxy statement.The dollar amounts reported in this column represent the amount of “compensation actually paid” to the PEO and average amount of “compensation actually paid” to Non-PEO NEOs as a group in the applicable year as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the Non-PEO NEOs as a group during the applicable year.
In accordance with the requirements of Item 402(v) of Regulation S-K, the adjustments in the table below were made to the total compensation for the PEO and the average total compensation for the Non-PEO NEOs as a group for 2025 to determine the compensation actually paid.

Compensation Actually Paid vs. Total Shareholder Return
For the four-year period shown in the table above, the amount of CAP for our PEO Paul Prager is not generally aligned with our TSR because Mr. Prager did not receive any equity-related compensation during such period. By contrast, our Non-PEO NEOs receive equity awards, which vary in value year-to-year depending on our stock price. As a result, the amount of CAP for our Non-PEO NEOs is somewhat related to our TSR over time. For example, PSUs, which are an integral part of our executive compensation program for our Non-PEO NEOs, are related to Company performance, although not directly tied to TSR, because they provide value only if the price of our common stock increases, subject to the NEO’s continued employment over the applicable performance period. These PSU awards strongly align our Non-PEO NEOs’ interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our Non-PEO NEOs to continue in our employment for the long term. In addition, our CAP for our PEO and Non-PEO NEOs is generally aligned with our net loss for the years shown in the table above.
