Explanation of responses 2 footnotes

Footnote F1

Each Restricted Stock Unit granted under the Plexus Corp. 2024 Omnibus Incentive Plan, which qualifies under Rule 16b-3, represents a contingent right to receive one share of Plexus Corp. common stock. The Restricted Stock Units vest on February 9, 2029.

Footnote F2

Each Performance Stock Unit ("PSU") granted under the Plexus Corp. 2024 Omnibus Incentive Plan, which qualifies under Rule 16b-3, represents a contingent right to receive one share of Plexus Corp. common stock if certain conditions are satisfied. Vesting of 450 PSUs is dependent on the relative total shareholder return ("TSR") of Plexus Corp.'s common stock as compared to companies in the S&P 400 Index and vesting of the remainder is based on goals related to economic return ("ER") during the three-year performance period. The target number of PSUs that may be earned is reported above. The reporting person may earn up to 150% of the targeted amount that is based on TSR and up to 200% of the targeted amount that is based on ER.
