Named Executive Officers, Footnote |  |  | Mr. Maheswaran ("CEO #1") was our CEO for all of fiscal years 2021, 2022 and 2023 and during fiscal year 2024 from January 30, 2023 through June 29, 2023. Mr. Pickle ("CEO #2") was our CEO during fiscal year 2024 from June 30, 2023 through January 28, 2024. For fiscal year 2021, 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. |  |  |
Adjustment To PEO Compensation, Footnote |  |  | 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 following table provides a reconciliation of the Summary Compensation Table Total to Compensation Actually Paid for our CEO#1.

Compensation Actually Paid vs. Total Shareholder Return |  |  | Semtech TSR represents cumulative total shareholder return on a fixed investment of $100 in the Company’s common stock for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. Philadelphia Semiconductor Index TSR represents cumulative total shareholder return on a fixed investment of $100 in the Philadelphia Semiconductor Index (“PHLX”) for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last four fiscal years against the Company’s total shareholder return and the total shareholder return for the Philadelphia Semiconductor Index (each calculated as described above) over that period of time. |  |  |
Compensation Actually Paid vs. Net Income |  |  | This column shows the Company’s net income for each fiscal year covered by the table. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last four fiscal years against the Company’s net income for each of those years. |  |  |
Compensation Actually Paid vs. Company Selected Measure |  |  | This column shows the Company’s non-GAAP operating income for each fiscal year covered by the table. See Exhibit A for a reconciliation of non-GAAP operating income for fiscal years 2023 and 2024 to the most directly comparable GAAP measures (and the corresponding exhibit to our proxy statement for prior fiscal years). We consider non-GAAP operating income to be a key metric in our executive compensation program, used in determining the fiscal year 2024 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 four fiscal years against the Company’s non-GAAP operating income for each of those years. |  |  |
Total Shareholder Return Vs Peer Group |  |  | Semtech TSR represents cumulative total shareholder return on a fixed investment of $100 in the Company’s common stock for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. Philadelphia Semiconductor Index TSR represents cumulative total shareholder return on a fixed investment of $100 in the Philadelphia Semiconductor Index (“PHLX”) for the period beginning on the last trading day of fiscal year 2020 through the end of the applicable fiscal year, and is calculated assuming the reinvestment of dividends. The following chart illustrates the CAP for our CEO and the average CAP for our Non-PEO NEOs for each of the last four fiscal years against the Company’s total shareholder return and the total shareholder return for the Philadelphia Semiconductor Index (each calculated as described above) over that period of time. |  |  |
