(1)	The dollar amounts reported are the amounts of total compensation reported in the Summary Compensation Table (“SCT”) for our CEO (“Principal Executive Officer” or “PEO”).

(2)

The dollar amounts reported represent the amount of CAP for the PEO, as computed in accordance with SEC rules. The dollar amounts do not reflect the actual amount of compensation earned by or paid to an executive during the applicable year. CAP includes year-over-year changes in the value of unvested equity awards, and therefore may not reflect the value ultimately realized upon vesting of the awards. In accordance with SEC rules, the following adjustments were made to total compensation to determine the CAP:


Year	SCT Total ($)	Less SCT Stock Awards ($)^(a)	Less SCT Pension Value ($)^(b)	Plus CAP Equity Adjustment ($)^(c)	Plus CAP Pension Adjustment ($)^(d)	Compensation Actually Paid ($)

applicable year; and (iii) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows:

Compensation Actually Paid vs. Total Shareholder Return [Text Block]

Compensation Actually Paid and TSR

As detailed under “Executive Compensation – Compensation Discussion and Analysis” in this Proxy Statement, equity awards comprise a significant portion of SCT compensation for our executives (slightly more than 50% for the CEO and approximately 40% for other NEOs). Accordingly, positive TSRs for 2020 and 2021 resulted in higher CAP. Higher year-over-year stock prices drove higher values

realized upon vesting of awards, and, for unvested awards, higher year-end valuations. In 2022, negative TSR resulted in negative CAP equity adjustments and significantly lower CAP for all NEOs.

The following chart compares CAP to the Company’s TSR. The cumulative total return shown in the chart below assumes an initial investment of $100 on the last trading day of the year ended December 31, 2019, including reinvestment of dividends, at each fiscal year end and measures the performance of this investment as of the last trading day in the month of December for each of the three years ended December 31, 2020, December 31, 2021 and December 31, 2022. The graph is a historical representation of past performance only and is not necessarily indicative of future performance.

CAP and TSR

Cumulative value of $100 invested in Matson common stock on December 31, 2019, including reinvestments of dividends

As described under “Executive Compensation – Compensation Discussion and Analysis – Components of Executive Compensation – Equity-Based Compensation” in this Proxy Statement, relative TSR is the metric for a portion of the Performance Shares granted to our executives. Changes in equity value attributed to share price applies to both Performance Shares and Restricted Stock Units whereas the relative TSR metric only applies to Performance Shares.

Compensation Actually Paid vs. Net Income [Text Block]

Compensation Actually Paid and Net Income

Net income is not a specific performance metric in the Company’s compensation program. As described under “Compensation Actually Paid and TSR” above, the Company uses EBITDA as an earnings metric under the annual cash incentive plan. In 2022, while Matson reported an extraordinary level of net income, CAP was down significantly, as discussed above under “Compensation Actually Paid and TSR”. The chart below compares CAP to net income.

Compensation Actually Paid vs. Company Selected Measure [Text Block]

Compensation Actually Paid and EBITDA

Earnings before interest, income taxes, depreciation, and amortization (“EBITDA”) is Matson’s company-selected performance measure. For 2020, 2021 and 2022, the Company achieved extraordinary results as determined by pre-established goals of the performance plan, which resulted in maximum payouts under the corporate portion of the Company’s annual cash incentive plan. For 2022, CAP was down compared to prior years due to the impact of share price declines (see “Compensation Actually Paid and TSR” below for more information). The following chart compares compensation actually paid to EBITDA.

The cumulative total return shown in the chart below assumes an initial investment of $100 on the last trading day of the year ended December 31, 2019, including reinvestment of dividends, at each fiscal year end and measures the performance of this investment as of the last trading day in the month of December for each of the three years ended December 31, 2020, December 31, 2021 and December 31, 2022. The graph is a historical representation of past performance only and is not necessarily indicative of future performance.
