Additional 402(v) Disclosure

The dollar amounts reported represent the amount of "compensation actually paid," as calculated in accordance with SEC rules. The dollar amounts do not reflect the actual amounts of compensation paid to our executives during the applicable year. In accordance with SEC rules, certain adjustments were made to the "Summary Compensation Table" total compensation to determine the amount of "compensation actually paid," including adding (i) the year-end fair value of equity awards granted during the reported year, and (ii) the change in the fair value of equity awards that were unvested at the end of the prior year, measured through the date the awards vested or were forfeited, or through the end of the reported fiscal year. For purposes of calculating "compensation actually paid," the fair value of equity awards is calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (FASB ASC Topic 718) using the same assumption methodologies used to calculate the grant date fair value of awards for purposes of the "Summary Compensation Table" (see page 50 for additional information).Effective November 18, 2024, Mr. Moorthy retired as PEO and Mr. Sanghi was appointed as PEO and Chair of the Board.

(5)Effective March 1, 2021, Mr. Sanghi transitioned from PEO and Chair of the Board of Directors to an Executive Chair role, and Mr. Moorthy was appointed as PEO and continued to serve as President.

(6)Pursuant to SEC rules, the Microchip TSR and Peer Group TSR are determined based on the value of an initial fixed investment of $100 on March 31, 2020 through the end of the listed fiscal year.

Represents GAAP net (loss) income for each of the years shown.

In accordance with SEC rules, the following table lists the financial performance measures that, in our assessment, represent the unranked, but most important financial performance measures used to link "compensation actually paid" to our NEOs to company performance for fiscal 2025, as further described in our Compensation Discussion and Analysis within the sections titled "Elements of Compensation - Base Salaries" (see page 37) and "Elements of Compensation - Equity Compensation" (see page 39).
