Mr. Maheswaran ("CEO #1") was our CEO for all of fiscal years 2022 and 2023 and during fiscal year 2024 from January 30, 2023 through June 29, 2023. Mr. Pickle ("CEO #2") was our CEO for fiscal year 2024 and 2025 from June 30, 2023 through June 6, 2024. Dr. Hou (“CEO #3”) was our CEO during fiscal year 2025 and 2026 from June 6, 2024 through January 25, 2026. For fiscal year 2022, our Non-PEO NEOs were Messrs. Chukwu, Beauchamp, Fulton and Silberstein. For fiscal year 2023, our Non-PEO NEOs were Messrs. Chukwu, Ammann, Beauchamp, Silberstein, Fulton and Chang. For fiscal year 2024, our Non-PEO NEOs were Messrs. Lin, Rodensky, Silberstein, Wilson, Chukwu and Ammann and Ms. McGee. For fiscal year 2025, our Non-PEO NEOs were Messrs. Lin, Silberstein, Rayabhari and Russel. For fiscal year 2026, our Non-PEO NEOs were Messrs. Lin, Silberstein, Green, Rayabhari and Wilson.

(2)
The average compensation for the CEOs and the Non-PEO NEOs for fiscal year 2026 was calculated from the Summary Compensation Table above. The average compensation for the CEO and the Non-PEO NEOs for each of the prior fiscal years was calculated from the Summary Compensation Table as disclosed in the Company’s Proxy Statement filed with the SEC in the calendar year in which that fiscal year ended.

(3)
For purposes of this table, the compensation actually paid (also referred to as “CAP”) to each of our NEOs (including, for purposes of this table, former named executive officers who are included in the Non-PEO NEO group for the applicable year) means the NEO’s total compensation as reflected in the Summary Compensation Table for the applicable fiscal year and adjusted for the following with respect to each NEO:

• Less the amounts reported in the “Stock Awards” and “Option Awards” columns of the Summary Compensation Table for the applicable fiscal year,

• Plus the fiscal year-end value of Semtech option and stock awards granted in the covered fiscal year which were outstanding and unvested at the end of the covered fiscal year,

• Plus/(less) the change in value as of the end of the covered fiscal year as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and were outstanding and unvested at the end of the covered fiscal year,

• Plus the vesting date value of Semtech option and stock awards which were granted and vested during the same covered fiscal year,

• Plus/(less) the change in value as of the vesting date as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and vested in the covered fiscal year,

• Less, as to any Semtech option and stock awards which were granted in prior fiscal years and were forfeited during the covered fiscal year, the value of such awards as of the end of the prior fiscal year,

• Plus the dollar value of any dividends or other earnings paid during the covered fiscal year on outstanding and unvested Semtech stock awards (no dividends or dividend equivalents were paid or credited with respect to Semtech options or stock awards during the applicable fiscal years),

• Plus, as to a Semtech option or stock award that was materially modified during the covered fiscal year, the amount by which the value of the award as of the date of the modification exceeds the value of the original award on the modification date (none of the Semtech option or stock awards held by the NEOs were materially modified during the fiscal years covered by the table).

In making each of these adjustments, the “value” of an option or stock award is the fair value of the award on the applicable date determined in accordance with FASB ASC Topic 718 using the valuation assumptions we then used to calculate the fair value of our equity awards. For more information on the valuation of our equity awards, please see the notes to our financial statements that appear in our Annual Report on Form 10-K each fiscal year and the footnotes to the Summary Compensation Table that appears in our annual Proxy Statement.

The Pay Versus Performance table above reflects the CAP (determined as noted above) for our CEO and, for our Non-PEO NEOs, the average of the CAPs determined for the Non-PEO NEOs for each of the fiscal years shown in the table.

For purposes of this table, the compensation actually paid (also referred to as “CAP”) to each of our NEOs (including, for purposes of this table, former named executive officers who are included in the Non-PEO NEO group for the applicable year) means the NEO’s total compensation as reflected in the Summary Compensation Table for the applicable fiscal year and adjusted for the following with respect to each NEO:

• Less the amounts reported in the “Stock Awards” and “Option Awards” columns of the Summary Compensation Table for the applicable fiscal year,

• Plus the fiscal year-end value of Semtech option and stock awards granted in the covered fiscal year which were outstanding and unvested at the end of the covered fiscal year,

• Plus/(less) the change in value as of the end of the covered fiscal year as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and were outstanding and unvested at the end of the covered fiscal year,

• Plus the vesting date value of Semtech option and stock awards which were granted and vested during the same covered fiscal year,

• Plus/(less) the change in value as of the vesting date as compared to the value at the end of the prior fiscal year for Semtech option and stock awards which were granted in prior fiscal years and vested in the covered fiscal year,

• Less, as to any Semtech option and stock awards which were granted in prior fiscal years and were forfeited during the covered fiscal year, the value of such awards as of the end of the prior fiscal year,

• Plus the dollar value of any dividends or other earnings paid during the covered fiscal year on outstanding and unvested Semtech stock awards (no dividends or dividend equivalents were paid or credited with respect to Semtech options or stock awards during the applicable fiscal years),

Tabular List, Table

Following is an unranked list of the Company’s financial performance measures we consider most important in linking the compensation actually paid to our NEOs for fiscal year 2026 with the Company’s performance.

• Relative TSR (used to determine vesting in our PSUs)

• Non-GAAP Adjusted Operating Income (used in both our PSUs and our Executive Bonus Plan)

• Net Sales (used in both our PSUs and our Executive Bonus Plan)

See the Compensation Discussion and Analysis section of this Proxy Statement for more information regarding the use of these performance measures in our executive compensation program.

Non-GAAP Adjusted Operating Income

Non-GAAP Measure Description

(6)
This column shows the Company’s non-GAAP adjusted operating income for each fiscal year covered by the table. See Exhibit A for a reconciliation of non-GAAP adjusted operating income for fiscal years 2025 and 2026 to the most directly comparable GAAP measures (and the corresponding exhibit to our proxy statement for prior fiscal years). We consider non-GAAP adjusted operating income to be a key metric in our executive compensation

program, used in determining the fiscal year 2026 annual bonuses for our NEOs. See the Compensation Discussion and Analysis section of this Proxy Statement for more information regarding the use of this performance measure in our executive compensation program. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last five fiscal years against the Company’s non-GAAP adjusted operating income for each of those years.
