As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive “compensation actually paid” and certain financial performance measures of the company. For information concerning the company’s pay for performance philosophy and how the company aligns executive compensation with the company’s performance, refer to the Compensation Discussion and Analysis beginning on page 59.

It is important to note that the "Total" amount set forth in the Summary Compensation Table (SCT) and the compensation actually paid (CAP) in the Pay Versus Performance (PVP) Table are not directly comparable. Each year presented in the SCT includes only the equity compensation granted during that year, whereas each year's CAP includes: (a) the year-end fair value of equity awards granted during the year, (b) the change in value during the year of unvested prior year equity awards and (c) the change in value from the beginning of the year to the vesting date for awards that vested during the year. Thus, the CAP includes both amounts paid or earned, as well as amounts derived from incremental accounting valuations for unvested equity awards that may never be earned or that could have different intrinsic values when earned.

In accordance with the SEC’s disclosure requirements, the following table sets forth information pertaining to the compensation of our principal executive officer (PEO) and our non-PEO named executive officers (collectively, the "other NEOs") and certain financial performance measures, for each of the fiscal years ended December 31, 2020, 2021, 2022 and 2023.

(1) The dollar amounts reported in this column are the amounts reported for our PEO, Mr. McKenney (the Chief Executive Officer), for each of the corresponding years in the "Total" column in the SCT above.

(2)The dollar amounts reported in this column represent the CAP to Mr. McKenney, as computed in accordance with Item 402(v) of Regulation S-K and do not reflect the total compensation actually realized or received by Mr. McKenney. In accordance with these rules, these amounts reflect the "Total" as set forth in the SCT for each year, adjusted as shown below. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

(a) Mr. McKenney's SCT Total for 2022 was corrected from what was previously reported in the 2023 Proxy Statement due to an inadvertent omission of incremental costs associated with deadhead flights for his personal use of the company aircraft in the "All Other Compensation" column of the Summary Compensation Table on page 89. This increased Mr. McKenney's 2022 SCT Total by $6,522.

(3)The dollar amounts reported in this column represent the average of the amounts reported for our other NEOs as a group (excluding Mr. McKenney) in the "Total" column of the SCT in each applicable year. The names of each of the other NEOs included for these purposes in each applicable year are as follows: (i) for 2023, 2022 and 2020, Messrs. Zabel, Simonds and Arnold and Ms. Iglesias; and (ii) for 2021, Messrs. Zabel, Simonds and Bhasin and Ms. Iglesias.

(4)The dollar amounts reported in this column represent the average CAP for the other NEOs as a group, as computed in accordance with Item 402(v) of Regulation S-K. In accordance with these rules, these amounts do not reflect the total compensation actually realized or received. In accordance with these rules, these amounts reflect the average "Total" as set forth in the SCT for each year, adjusted as shown below. Equity values are calculated in accordance with FASB ASC Topic 718, and the valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

(5) Total Shareholder Return (TSR) is calculated by dividing the sum of (i) the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and (ii) the difference between the company’s share price at the end of each fiscal year shown and the beginning of the measurement period by (b) the company’s share price at the beginning of the measurement period. The beginning of the measurement period for each year in the table is December 31, 2019.

(6)The peer group used for this purpose is the S&P 500 Life & Health Insurance Sub Industry Index, which is consistent with the disclosure required under Regulation S-K Item 201(e).

(7) The dollar amounts reported represent the amount of net income reflected in the company’s audited financial statements for the applicable year.

(8) The company-selected measure (CSM) isafter-tax adjusted operating earnings per share (EPS), which is defined as net income adjusted to exclude after-tax net investment gains or losses and amortization of the cost of reinsurance as well as certain other items specified in the reconciliation of non-GAAP financial measures in Appendix A of this proxy statement divided by dilutive outstanding weighted average shares. Investment gains or losses primarily include realized investment gains or losses, expected investment credit losses, and gains or losses on derivatives.

(9) Prior financial information has been adjusted to reflect our modified retrospective adoption, effective January 1, 2023, of the ASU 2018-12, related to targeted improvements to the accounting for long-duration contracts. Changes from this ASU were applied as of January 1, 2021, also referred to as the transition date. As a result of such adjustments, the dollar amounts reported in the PVP Table for net income and after-tax adjusted operating earnings per share (EPS) for 2021 and 2022 are different than those reported in the PVP Table in our 2023 Proxy Statement.

Relationships Between Compensation Actually Paid and Performance Measures

As described in more detail in the Compensation Discussion and Analysis section above, the company's executive compensation program reflects a variable pay-for-performance philosophy. While the company utilizes several performance measures to align executive compensation with company performance, all of those measures are not presented in the PVP table above. Moreover, as discussed above, the company generally seeks to incentivize long-term performance, and therefore does not specifically align the company's performance measures with CAP for a particular year. In accordance with SEC rules, the following information explains how the CAP to our PEO, as well as the average CAP to our other NEOs, each compares to our cumulative total shareholder return (TSR), net income, and after-tax adjusted operating earnings per share. We have also addressed how our three-year TSR compares to the three-year TSR of the S&P 500 Life & Health Insurance Sub Industry Index ("S&P Life & Health Index").

Over the period from 2020 to 2023, like many other companies, we have faced challenges as the COVID-19 pandemic caused significant disruption to global markets, employment and business. During 2020 and 2021, we experienced significant increases in COVID-based claims incidence in our group life and disability lines, as well as leaves administered through our leave management business. During 2022 and continuing in 2023, the impacts of COVID-19 lessened and we returned to pre-pandemic operating levels, resulting in record earnings and strong growth.

Compensation actually paid to our PEO and other NEOs directionally aligns with our financial performance as summarized below.

•2023: The CAP to our PEO and other NEOs decreased relative to 2022, by 8.6% and 12.5%, respectively. There was an 8.8%(1) decrease in net income over 2022, as a result of unfavorable reserve assumption updates and increased operating expenses. Overall, the company experienced a strong financial year with a 19.7%(1) increase in after-tax adjusted operating earnings per share. Our TSR increased 13.7% in 2023 and we outperformed other peer companies in the S&P Life & Health Index.

•2022: The CAP to our PEO and other NEOs increased relative to 2021 and 2020, which was reflective of an excellent year for the company in 2022, as evidenced by 42.9%(1) growth in after-tax adjusted operating earnings per share, 43.4%(1) growth in net income, and TSR well above the S&P Life & Health Index and other peer companies. Other key factors driving the increase in CAP were the increase in achievement of our 2020 performance share unit (PSU) grant as well as the increase in our stock price during 2022.

•2021: The CAP to our PEO was 5.4% lower, and the average CAP for other NEOs was 5.5% higher, than 2020. We had solid financial results despite negative impacts of the COVID-19 pandemic, with after-tax adjusted operating earnings per share 9.1%(1)lower and net income higher than 2020. Our TSR, though still lagging the S&P Life & Health Index TSR, was up 11.8% relative to 2020.

•2020: With the onset of the pandemic during the year, we experienced lower after-tax adjusted operating earnings per share and net income levels than historical performance. Our TSR was more negatively impacted than the S&P Life & Health Index and other peer companies due in part to the impact of historically

low interest rates and investor perceptions surrounding the long-term care industry. The CAP to our PEO and other NEOs was impacted by a one-time special performance grant during the year that was designed to encourage the achievement of critical business outcomes and to incent executives to continue employment with the company over the long term.

(1) Prior financial information has been adjusted to reflect our modified retrospective adoption, effective January 1, 2023, of the ASU 2018-12, related to targeted improvements to the accounting for long-duration contracts. Changes from this ASU were applied as of January 1, 2021, also referred to as the transition date. As a result of such adjustments, the dollar amounts reported in the PVP Table for net income and after-tax adjusted operating earnings per share (EPS) for 2021 and 2022 are different than those reported in the PVP Table in our 2023 Proxy Statement.

Financial Performance Measures

The metrics that the company uses for both short- and long-term incentive awards are selected based on an objective of incentivizing NEOs to increase the value of our enterprise for our shareholders. The most important financial performance measures used by the company to link executive compensation actually paid to the PEO and other NEOs, for the most recently completed fiscal year, to the company’s performance are as follows:

Most Important Performance Measures

After-tax adjusted operating earnings per share(1)

Consolidated adjusted operating return on equity(2)

Earned premium(3)

Sales

Relative total shareholder return

(1) After-tax adjusted operating earnings per share is defined as net income adjusted to exclude after-tax net investment gains or losses, amortization of the cost of reinsurance, non-contemporaneous reinsurance, and reserve assumption updates, as well as certain other items specified in the reconciliation of non-GAAP financial measures in Appendix A of the proxy statement divided by dilutive outstanding weighted average shares. Information about the non-GAAP financial measures used in this proxy statement is set forth in “A Note About Non-GAAP Financial Measures” on page 2. For a reconciliation of the most directly comparable GAAP financial measures to the non-GAAP financial measures, refer to Appendix A of this proxy statement.

(2) Consolidated adjusted operating return on equity is calculated by dividing after-tax adjusted operating income by the average of the beginning- and end-of-year stockholders’ equity adjusted to exclude the net unrealized gain or loss on securities and the net gain or loss on hedges. Information about the non-GAAP financial measures used in this proxy statement is set forth in “A Note About Non-GAAP Financial Measures” on page 2. For a reconciliation of the most directly comparable GAAP financial measures to the non-GAAP financial measures, refer to Appendix A of this proxy statement.

(3) Earned premium is calculated for our core operations (Unum US, Unum International, and Colonial Life).
