Compensation Actually Paid vs. Total Shareholder Return |  | The charts below illustrate the relationship between compensation actually paid and the total shareholder return of Myriad and the IXHC for the periods presented which shows what the cumulative value of $100 would be, including the reinvestment of dividends, if such amount were invested on June 30, 2019. (1) PEO data for fiscal years 2024, 2023, 2022, and 2021 represent the compensation actually paid to Mr. Diaz only in those years. 2020 transition period PEO data reflects the sum of Messrs. Diaz’s and Riggsbee's compensation actually paid in this period. PEO data for fiscal year 2020 reflects the sum of Messrs. Riggsbee's and Capone's compensation actually paid in this fiscal year. |  |  |  |

Additional 402(v) Disclosure |  | Effective January 1, 2021, the Company transitioned from a fiscal year ending June 30 to December 31. Therefore, there was a six-month transition period in 2020 representing the period from July 1, 2020 to December 31, 2020. Equity values are calculated in accordance with FASB ASC Topic 718. For PSUs, the grant date fair value of PSUs used for SCT calculations assumes target performance for the 2024, 2023, 2022 and 2021 fiscal years and assumes the maximum level of performance for the 2020 transition period and 2020 fiscal year. To determine the year-end fair values used in the "compensation actually paid" calculations, we have updated the performance expectations to reflect the latest performance estimates for unvested and outstanding PSUs at each fiscal year end date. For options awards, updated market input assumptions (stock price, risk free interest rate, volatility, expected term, and future dividend yield expectations) have been used to determine the fair values of outstanding awards as of the identified vesting dates and the relevant fiscal year end dates using the Black Scholes Merton option pricing model.As required under Item 201(e) of Regulation S-K, total shareholder return measures the cumulative value of $100 invested on the last trading day before the earliest fiscal year in the table, or June 30, 2019, including the reinvestment of dividends, through and including the end of the applicable fiscal year for which total shareholder return is calculated, or June 30, 2020, December 31, 2020, December 31, 2021, December 31, 2022, December 31, 2023 and December 31, 2024, respectively. Revenue is a GAAP financial measure and does not exclude revenue from divested businesses.Engagement score and Customer NPS are non-financial quantitative metrics designed to support our efforts to retain employees and improve employee engagement and enhance customer experiences. As discussed above in our "Compensation Discussion and Analysis" section of this proxy statement, our compensation program seeks to align compensation with Company performance and reward our executive officers for their contribution to our growth, profitability and increased stockholder value. Additional details on the elements of our executive compensation program and our pay-for-performance compensation philosophy are set forth above in the "Compensation Discussion and Analysis" section. The compensation actually paid to our PEO and the other NEOs in each of the periods reported above and over the 5.5 year cumulative period shows how the compensation actually paid fluctuated year-over-year. The fluctuations in compensation actually paid were primarily due to changes in our stock price measured as of the last day of each listed period, which we believe demonstrates the "pay-for-performance" nature of our executive compensation program. As the tables above illustrate, the compensation actually paid to our PEO and the other NEOs was higher when our stock price performed well and lower when our stock price did not perform well. We believe this correlation between compensation actually paid and total shareholder return over the applicable measurement periods also shows that our performance-based equity incentives builds alignment between executive compensation and stockholder returns. |  |  |  |
