Adjusted EBITDA and Distributable Cash Flow, as adjusted, are non-GAAP financial measures of performance that have limitations and should not be considered as a substitute for net income. Please refer to the discussion and tables under “Supplemental Information” later in this news release for a discussion of our use of Adjusted EBITDA and Distributable Cash Flow, as adjusted, and a reconciliation to net income.

Transaction-related expenses include certain one-time expenses incurred with acquisitions. The Partnership’s definition of Adjusted EBITDA includes transaction-related expenses. However, given the magnitude of the acquisitions during the periods presented, as well as the expenses related to those transactions, the Partnership is reporting Adjusted EBITDA excluding these expenses in order to portray the Partnership’s performance for the period without the impact of these one-time items.

Adjusted EBITDA is defined as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of asset, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, certain foreign currency transaction gains and losses and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. We define Distributable Cash Flow as Adjusted EBITDA less preferred unit distributions, cash interest expense, including the accrual of interest expense related to our long-term debt which is paid on a semi-annual basis, current income tax expense, maintenance capital expenditures and other non-cash adjustments. For Distributable Cash Flow, as adjusted, certain transaction-related adjustments and non-recurring expenses are excluded.

We believe Adjusted EBITDA and Distributable Cash Flow, as adjusted, are useful to investors in evaluating our operating performance because:

• Adjusted EBITDA is used as a performance measure under our revolving credit facility;
• securities analysts and other interested parties use such metrics as measures of financial performance, ability to make distributions to our unitholders and debt service capabilities;
• our management uses them for internal planning purposes, including aspects of our consolidated operating budget and capital expenditures; and
• Distributable Cash Flow, as adjusted, provides useful information to investors as it is a widely accepted financial indicator used by investors to compare partnership performance, and as it provides investors an enhanced perspective of the operating performance of our assets and the cash our business is generating.

Adjusted EBITDA and Distributable Cash Flow, as adjusted, are not recognized terms under GAAP and do not purport to be alternatives to net income as measures of operating performance or to cash flows from operating activities as a measure of liquidity. Adjusted EBITDA and Distributable Cash Flow, as adjusted, have limitations as analytical tools, and one should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP. Some of these limitations include:

• they do not reflect our total cash expenditures, or future requirements for capital expenditures or contractual commitments;
• they do not reflect changes in, or cash requirements for, working capital;
• they do not reflect interest expense or the cash requirements necessary to service interest or principal payments on our revolving credit facility or senior notes;
• although depreciation, amortization and accretion are non-cash charges, the assets being depreciated, amortized and accreted will often have to be replaced in the future, and Adjusted EBITDA does not reflect cash requirements for such replacements; and
• as not all companies use identical calculations, our presentation of Adjusted EBITDA and Distributable Cash Flow, as adjusted, may not be comparable to similarly titled measures of other companies.

Adjusted EBITDA reflects amounts for the unconsolidated affiliates based on the same recognition and measurement methods used to record equity in earnings of unconsolidated affiliates. Adjusted EBITDA related to unconsolidated affiliates excludes the same items with respect to the unconsolidated affiliates as those excluded from the calculation of Adjusted EBITDA, such as interest, taxes, depreciation, amortization, accretion and other non-cash items. Although these amounts are excluded from Adjusted EBITDA related to unconsolidated affiliates, such exclusion should not be understood to imply that we have control over the operations and resulting revenues and expenses of such affiliates. We do not control our unconsolidated affiliates; therefore, we do not control the earnings or cash flows of such affiliates. The use of Adjusted EBITDA or Adjusted EBITDA related to unconsolidated affiliates as an analytical tool should be limited accordingly. Inventory valuation adjustments that are excluded from the calculation of Adjusted EBITDA represent changes in lower of cost or market reserves on the Partnership's inventory. These amounts are unrealized valuation adjustments applied to fuel volumes remaining in inventory at the end of the period.

For the three months ended March 31, 2026 and 2025, excludes nil and $2 million, respectively, for our proportionate share of maintenance capital expenditures related to our investments in ET-S Permian and J.C. Nolan, as these amounts are included in “Distributable cash flow from unconsolidated affiliates.”

For the three months ended March 31, 2026 and 2025, SUN incurred $9 million and nil of transaction-related expenses, respectively.

Limited Partner units outstanding at the end of period includes 136.9 million common units and 51.5 million Class D units.

Adjusted EBITDA is defined as net income before net interest expense, income tax expense, depreciation, amortization and accretion expense, non-cash compensation expense, gains and losses on disposal of asset, non-cash impairment charges, losses on extinguishment of debt, unrealized gains and losses on commodity derivatives, inventory valuation adjustments, certain foreign currency transaction gains and losses and certain other operating expenses reflected in net income that we do not believe are indicative of ongoing core operations. We define Distributable Cash Flow as Adjusted EBITDA less preferred unit distributions, cash interest expense, including the accrual of interest expense related to our long-term debt which is paid on a semi-annual basis, current income tax expense, maintenance capital expenditures and other non-cash adjustments. On a consolidated basis, Distributable Cash Flow includes 100% of the Distributable Cash Flow of Sunoco LP; however, given the existence of noncontrolling interests in Sunoco LP, the Distributable Cash Flow generated by Sunoco LP is not available in its entirety to be distributed to SunocoCorp’s unitholders. In order to reflect the cash flows available for distribution to SunocoCorp’s unitholders, we have reported for SunocoCorp Distributable Cash Flow attributable to its common unitholders, which reflects distributions to be received by SunocoCorp from Sunoco LP.

We believe Adjusted EBITDA and Distributable Cash Flow are useful to SunocoCorp's investors in evaluating its performance because:

• Adjusted EBITDA is used as a performance measure under our revolving credit facility;
• securities analysts and other interested parties use such metrics as measures of financial performance, ability to make distributions to our unitholders and debt service capabilities;
• our management uses them for internal planning purposes, including aspects of our consolidated operating budget and capital expenditures; and
