(1)

Our principal executive officer (“PEO”) in all reporting years is Chris Diorio, Ph.D. Our non-PEO named executive officers (“Non-PEO NEOs”) for the 2025 reporting year are Cary Baker, Hussein Mecklai and Cathal Phelan. Our Non-PEO NEOs for the 2024 and 2023 reporting years are Cary Baker, Jeffrey Dossett, Hussein Mecklai and Cathal Phelan. Our Non-PEO NEOs for the 2022 reporting year are Cary Baker, Jeffrey Dossett and Hussein Mecklai. Our Non-PEO NEOs for the 2021 reporting year are Cary Baker and Jeffrey Dossett.

(2)

CAP does not mean that our PEO was actually paid those amounts in the listed year, but this is a dollar amount derived from the starting point of SCT total compensation under the methodology prescribed under the SEC’s rules, as shown in the adjustment table below:

(3) The fair value of stock options reported for CAP purposes is estimated using a Black-Scholes option pricing model for the purposes of this PVP calculation in accordance with the SEC rules. Stock options were a component of CAP in 2024, 2023, 2022 and 2021. We estimate the fair value of options using the Black-Scholes option-pricing model with the following assumptions for the periods presented:


Grant Year	2025	2024	2023	2022	2021
Volatility		69.19-71.94%	68.3 - 78.41%	66.64 - 77.33%	67.05 - 80.73%
Expected life in years		3.04-3.27 years	3.04 - 3.78 years	2.98 - 4.29 years	3.10 - 4.94 years
Expected dividend yield		0.00%	0.00%	0.00%	0.00%
Risk-free rate		4.01-4.77%	3.54 - 5.44%	1.00 - 4.57%	0.06 - 1.44%

(4) This figure is the average of compensation actually paid for the Non-PEO NEOs in each covered year. CAP does not mean that these Non-PEO NEOs were actually paid those amounts in the listed year, but this is a dollar amount derived from the starting point of SCT total compensation under the methodology prescribed under the SEC’s rules, as shown in the adjustment table below:

(5) TSR is determined based on the value of an initial fixed investment of $100 in our common stock on December 31 of the year prior to the earliest year for which disclosure is required, assuming the reinvestment of any dividends. The peer group is made up of the PHLX Semiconductor Sector Index, which is the peer group we used for the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report on Form 10-K for the year ended December 31, 2025.

(6) The dollar amounts reported represent our net loss as reflected in our audited financial statements.

(7) The dollar amounts reported represent our revenue as reflected in our audited financial statements.

(8) Adjusted EBITDA is a non-GAAP financial measure. For a reconciliation of non-GAAP financial measures, see Appendix A.

Annual grants are typically made in the first quarter of the fiscal year. The Compensation Committee (or the Board when appropriate) typically grant equity awards during an open trading window. We do not make equity grants in anticipation of the release of material, nonpublic information, and, we have not taken, nor do we intend to take, material nonpublic information into account when determining the terms of equity grants.
