F1	Each restricted stock unit represents a contingent right to receive one share of Microchip Technology Incorporated common stock.
F2	The restricted stock units will vest in full on November 15, 2029 as long as the individual remains a service provider through the vesting date. Vested shares will be delivered to the reporting person upon vest.
F3	Each performance stock unit represents a contingent right to receive one share of Microchip Technology Incorporated common stock.
F4	Each Performance Stock Unit (PSU) granted under the Microchip Technology Incorporated (Microchip) 2004 Equity Incentive Plan represents a contingent right to receive shares of Microchip common stock based on Microchip's cumulative non-GAAP operating margin over a period of 12 quarters ending September 30, 2028. The target number of PSU shares that may be earned is reported in the table above and is based on Microchip achieving a cumulative non-GAAP operating margin of 30.0% over the 12 quarter measurement period. The actual number of shares that may be earned can be higher or lower than the target depending on Microchip's non-GAAP operating margin over the measurement period. Earned PSUs will vest on November 15, 2029 as long as the reporting person remains a service provider through the vesting date. Vested shares will be delivered to the reporting person upon vest.
F5	This Amended Form 4 is filed to accurately report the non-GAAP operating margin as 30.0%. All subsequent reports filed after this date are deemed to include the modification herein.
