Peer Group Issuers, Footnote | The pay versus performance table above and the graph below compare the cumulative total shareholder return (TSR) on our common stock against the cumulative TSR of the stocks making up an industry peer group from December 31, 2019 through December 31, 2024. The industry peer group, which is consistent with the peer group used by the Company for its S-K Item 201(e) disclosures within the 2024 Annual Report on Form 10-K, is comprised of the following companies: CRA International, Inc. (CRAI), FTI Consulting, Inc. (FCN), ICF International, Inc. (ICFI), Premier, Inc. (PINC) and Resources Connection, Inc. (RGP). The graph and table assume a $100 investment in Huron Consulting Group Inc. common stock and an index of the industry peer group on December 31, 2019. The annual TSR for each member of the peer group assumes all dividends are reinvested and was weighted based on its stock market capitalization at the beginning of each year presented. |  |  |  |

Adjustment To PEO Compensation, Footnote | CAP was calculated by subtracting from the summary compensation total the grant date fair value of awards included in the summary compensation total, adding/(subtracting) the year-over-year change in fair value of unvested equity, adding/(subtracting) the year-over- year change in fair value of prior years' unvested equity that vested in the current year (valued as of the vest date), and adding the fair value of equity compensation granted in the current year (valued as of year-end). No dividends were paid in any year presented. (4)The Compensation Committee determined revenues before reimbursable expenses to be the most important financial performance measure used to link company performance to CAP to our PEO and Non-PEO NEOs for 2024 because, in its view, it was most consistent with our primary near-term objective of driving revenue growth. Please note that in 2024, the Company revised the line item description of revenues to rename revenues as revenues before reimbursable expenses. The change in line item description had no impact on the value of the company-selected measure in any period. Below is additional information on the total amount of equity compensation included in CAP for the PEO and the average amount of equity compensation included in CAP for the non-PEO NEOs for 2024:

Tabular List, Table | Financial Performance Measures The Compensation Committee uses the following four financial performance measures when determining actual compensation paid to the named executive officers: •Revenues before reimbursable expenses; •Organic revenues; •Adjusted EBITDA margin; and •Adjusted diluted earnings per share (“EPS”). |  |  |  |

Additional 402(v) Disclosure | The increase in the PEO and average Other NEO CAP in 2022 as compared to 2021 and 2020 is primarily due to the increase in the fair value of equity awards. From December 31, 2021 to December 31, 2022, our stock price increased from $49.90 to $72.60 and the expected funding of the 2020 and 2021 performance-based awards tied to performance against Adjusted Diluted EPS and Revenue Growth metrics increased from 0% to 19% for the 2020 awards and 100% to 153% for the 2021 awards. The increase in the PEO and average Other NEO CAP in 2023 also related to the increase in the fair value of equity awards. From December 31, 2022 to December 31, 2023, our stock price increased from $72.60 to $103.80 and the expected funding of the 2021 and 2022 performance-based awards tied to performance against Adjusted Diluted EPS and Revenue Growth metrics increased from 153% to 194% for the 2021 awards and 100% to 182% for the 2022 awards. The increase in the PEO CAP in 2024 related to the increase in the fair value of equity awards; and the decrease in the average Other NEO CAP in 2024 is primarily related to the departure of Mr. Torain effective March 15, 2024, partially offset by the increase in the fair value of equity awards outstanding with the other NEOs. The increase in the fair value of equity awards relates to the increase in our stock price from $103.80 to $124.26 from December 31, 2023 to December 31, 2024 and the expected funding of the 2022 and 2023 performance-based awards tied to performance against Adjusted Diluted EPS and Revenue Growth metrics increased from 194% to 200% for the 2022 awards and 100% to 168% for the 2023 awards. |  |  |  |
