| (4) | The Peer Group TSR set forth in this table utilizes the NASDAQ Biotechnology Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 29, 2024. The comparison assumes $100 was invested for the period starting December 29, 2019, through the end of the listed year in the Company and in the NASDAQ Biotechnology Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.
| (5) | We determined Core Illumina Revenue to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2024. Core Illumina Revenue is defined, for purposes of the variable compensation program, as set forth above in the “Compensation Discussion and Analysis” section. This performance measure may not have been the most important financial performance measure for prior years and we may determine a different financial performance measure to be the most important financial performance measure in future years.
