Vesting of Performance Share Units under 2012 Equity Incentive Plan

On September 9, 2013 and September 20, 2013, the Compensation Committee of the Board of Directors (the “Committee”) of Seagate Technology Public Limited Company (the “Company”) granted performance-vesting restricted share units (“PSUs”) to certain of the Company’s executive officers, including the named executive officers listed in the table below, under the terms of the Company’s 2012 Equity Incentive Plan, as amended. The PSUs were eligible to vest after the end of a three-year performance period, subject to continued employment and the achievement of average annual return on invested capital (“ROIC”) over the performance period, modified by a factor based on the Company’s relative total shareholder return (“TSR”) percentile compared with a selected peer group, as generally described under the heading “Compensation Discussion and Analysis— Long-Term Equity Incentives—Share Awards—Performance Share Units” on pages 67 and 68 of our proxy statement for our fiscal year ended June 27, 2014, filed with the Securities and Exchange Commission on September 3, 2014.

On September 26, 2016, the Committee certified the level of achievement of the financial performance metrics for the three-year performance period ended July 1, 2016. The PSUs will vest at 98% of target, on the basis of a three-year average annual ROIC of 54%, and relative TSR at the 18th percentile over the performance period.

The actual number of shares to be issued to the named executive officers listed in our 2016 proxy statement pursuant to the PSU vesting is shown in the table below.
