Change in Reporting Entity

SunocoCorp was previously named NuStar GP Holdings, LLC and was a consolidated subsidiary of Sunoco. SunocoCorp’s name was changed in 2025 in anticipation of the restructuring changes that occurred in connection with the Parkland Acquisition. Upon the consummation of the Parkland Acquisition, SunocoCorp became the primary beneficiary of Sunoco based on (i) SunocoCorp’s rights to appoint and remove the directors of Sunoco GP Board and (ii) SunocoCorp’s economic interest in Sunoco held via 100% of the Sunoco Class D Units; accordingly, management concluded that SunocoCorp should consolidate Sunoco. Given SunocoCorp’s consolidation of its previous parent (Sunoco) upon the consummation of the Parkland Acquisition, management of the Company concluded that the restructuring constituted a change in reporting entity under Accounting Standards Codification Topic 250 (“ASC 250”), because the consolidated financial statements of the Company are, in effect, the statements of a different reporting entity. Accordingly, the Company’s consolidated financial statements prior to the Parkland Acquisition have been retrospectively restated to reflect the consolidation of Sunoco for all periods, and Sunoco’s equity prior to the Parkland Acquisition is reflected as “predecessor equity” in the Company’s consolidated financial statements for those periods. Accordingly, the results of operations included herein also reflect the consolidation of Sunoco for all periods.

Net Income. For the three months ended March 31, 2026 compared to the same period last year, net income increased by$398 million, or approximately 192%, primarily due to higher Segment Adjusted EBITDA from multiple segments, with the most significant increases driven by the Parkland Acquisition and other acquisitions; these increases were partially offset by increases in depreciation, amortization and accretion and interest expense. These increases and decreases are discussed further below.

Adjusted EBITDA (consolidated). For the three months ended March 31, 2026 compared to the same period last year, Adjusted EBITDA increased primarily due to the Parkland Acquisition and other acquisitions.

Additional information on changes impacting net income and comprehensive income (loss) and Adjusted EBITDA for the three months ended March 31, 2026 compared to the same period last year is available below and in “Segment Operating Results.”

Depreciation, Amortization and Accretion. For the three months ended March 31, 2026 compared to the same period last year, depreciation, amortization and accretion increased primarily due to additional depreciation and amortization from assets recently placed in service and from recent acquisitions.

Interest Expense, net. For the three months ended March 31, 2026 compared to the same period last year, interest expense increased primarily due to an increase in average total long-term debt, including debt assumed in the Parkland Acquisition.

Unreal ized (Gains) Losses on Commodity Derivatives. The unrealized gains and losses on our commodity derivatives represent the changes in fair value of our commodity derivatives. The change in unrealized gains and losses between periods is impacted by the notional amounts and commodity price changes on our commodity derivatives. Additional information on commodity derivatives is included in “Item 3. Quantitative and Qualitative Disclosures about Market Risk” below.

Inventory Valuation Adjustments. Inventory valuation adjustments represent changes in lower of cost or market reserves using the LIFO method 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, the Partnership's cost of sales included favorable LIFO inventory valuation adjustments of $444 million and $61 million, respectively, which increased net income.

Adjusted EBITDA Related to Unconsolidated Affiliates and Equity in Earnings of Unconsolidated Affiliates. See additional information in “Supplemental Information on Unconsolidated Affiliates” and “Segment Operating Results.”

Income Tax Expense (Benefit). For the three months ended March 31, 2026 compared to the same period last year, income tax expense increased primarily due to increased corporate earnings from recent acquisitions.

Supplemental Information on Unconsolidated Affiliates

The following table presents financial information related to unconsolidated affiliates:

(1)These amounts represent our proportionate share of the Adjusted EBITDA of our unconsolidated affiliates and are based on our equity in earnings or losses of our unconsolidated affiliates adjusted for our proportionate share of the unconsolidated affiliates’ interest, depreciation, amortization, accretion, non-cash items and taxes.

Segment Operating Results

We evaluate segment performance based on Segment Adjusted EBITDA, which we believe is an important performance measure of the core profitability of our operations. This measure represents the basis of our internal financial reporting and is one of the performance measures used by senior management in deciding how to allocate capital resources among business segments.

The following tables identify the components of Segment Adjusted EBITDA, which is calculated as follows:

•Segment profit, operating expensesand selling, general and administrative expenses. These amounts represent the amounts included in our consolidated financial statements that are attributable to each segment.

•Adjusted EBITDA related to 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 Segment 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 following analysis of segment operating results includes a measure of segment profit. Segment profit is a non-GAAP financial measure and is presented herein to assist in the analysis of segment operating results and particularly to facilitate an understanding of the impacts that changes in sales revenues have on the segment performance measure of Segment Adjusted EBITDA. Segment profit is similar to the GAAP measure of gross profit, except that segment profit excludes charges for depreciation, amortization and accretion. The most directly comparable measure to segment profit is gross profit.

The following table presents a reconciliation of segment profit to gross profit:

In addition, for the Fuel Distribution segment, the following section includes information on the components of segment profit by sales type, which components are included in order to provide additional disaggregated information to facilitate the analysis of segment profit and Segment Adjusted EBITDA. These components of segment profit are calculated consistent with the calculation of segment profit; therefore, these components also exclude charges for depreciation, amortization and accretion.
