Closing of the Parkland Acquisition is subject to customary conditions, including, among other things, regulatory and stock exchange listing approvals. No assurance can be given that the Parkland Acquisition will be completed on the timeline currently contemplated or at all.

Item 7.01	Regulation FD Disclosure.

On September 4, 2025, the Partnership issued a press release announcing the pricing of the previously announced private offering of senior notes (the “Notes Offering”). A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated in this Item 7.01 by reference.

On September 4, 2025, the Partnership issued a press release announcing the pricing of the previously announced private offering of Series A Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units (the “Series A Preferred Units” and such offering, the “Preferred Offering”). A copy of the press release is furnished as Exhibit 99.2 to this Current Report on Form 8-K and is incorporated in this Item 7.01 by reference.

The information included herein (including the exhibits) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act except as shall be expressly set forth by specific reference in such a filing.

Neither the Notes Offering nor the Preferred Offering is contingent on the completion of the Parkland Acquisition, and neither the Notes Offering nor the Preferred Offering is contingent on the completion of the other.

However, if (x) the consummation of the Parkland Acquisition does not occur on or before May 5, 2026 (the “Special Mandatory Redemption Date”); or (y) prior thereto, the Partnership notifies the trustee or the paying agent, as applicable, in writing that (a) the Arrangement Agreement has been terminated, (b) the Partnership will not pursue the consummation of the Parkland Acquisition or (c) the Partnership has determined in its sole discretion that the Parkland Acquisition cannot or is not reasonably likely to be completed by the Special Mandatory Redemption Date, (i) the senior notes issued in the Notes Offering will be subject to a special mandatory redemption at a price equal to 100% of the initial issue price plus accrued and unpaid interest to, but not including, the Special Mandatory Redemption Date and (ii) the Series A Preferred Units issued in the Preferred Offering will be subject to a special mandatory redemption at a price equal to $1,000 per Series A Preferred Unit plus, in each case, an amount equal to all accumulated but unpaid distributions thereon to, but not including, the Special Mandatory Redemption Date, whether or not declared.

Forward Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act and Section 21E of the Exchange Act. In this context, forward-looking statements often address future business and financial events, conditions, expectations, plans or ambitions, and often include, but are not limited to, words such as “believe,” “expect,” “may,” “will,” “should,” “could,” “would,” “anticipate,” “estimate,” “intend,” “plan,” “seek,” “see,” “target” or similar expressions, or variations or negatives of these words, but not all forward-looking statements include such words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the

consummation of the proposed transaction and the anticipated benefits thereof. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of Sunoco and Parkland, that could cause actual results to differ materially from those expressed in such forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: the completion of the proposed transaction on the anticipated terms and timing, or at all, including obtaining regulatory approvals, court approvals and approval of the listing of the common units of SunocoCorp on the New York Stock Exchange; and the anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, prospects, business and management strategies for the management, expansion and growth of the combined company’s operations, including the possibility that any of the anticipated benefits of the proposed transaction will not be realized or will not be realized within the expected time period; the ability of Sunoco and Parkland to integrate the business successfully and to achieve anticipated synergies and value creation; potential litigation relating to the proposed transaction that could be instituted against Sunoco, Parkland or their directors; the risk that disruptions from the proposed transaction will harm Sunoco’s or Parkland’s business, including current plans and operations and that management’s time and attention will be diverted on transaction-related issues; potential adverse reactions or changes to business relationships, including with employees, suppliers, customers, competitors or credit rating agencies, resulting from the announcement or completion of the proposed transaction; the potential for modification or adjustment of the Arrangement Agreement; the parties’ ability to satisfy their respective conditions and consummate the transaction; rating agency actions and Sunoco and Parkland’s ability to access short-and long-term debt markets on a timely and affordable basis; potential business uncertainty, including the outcome of commercial negotiations and changes to existing business relationships during the pendency of the proposed transaction that could affect Sunoco’s and/or Parkland’s financial performance and operating results; certain restrictions during the pendency of the arrangement that may impact Parkland’s ability to pursue certain business opportunities or strategic transactions or otherwise operate its business; dilution caused by Sunoco’s issuance of additional units representing limited partner interests in connection with the proposed transaction; fees, costs and expenses and the possibility that the transaction may be more expensive to complete than anticipated; and those risks described (i) under the heading “Risk Factors” in the management information circular and proxy statement with respect to the Parkland Acquisition, as filed on the System for Electronic Data Analysis and Retrieval + in Canada (SEDAR+) and available on Parkland’s website at http://www.parkland.ca, (ii) under the headings “Cautionary Statement Regarding Forward-Looking Information” and “Risk Factors” in Parkland’s current Annual Information Form dated March 5, 2025, and under the headings “Forward-Looking Information” and “Risk Factors” included in the Q4 2024 Management’s Discussion and Analysis dated March 5, 2025, in the Q1 2025 Management’s Discussion and Analysis dated May 5, 2025 and in the Q2 2025 Management’s Discussion and Analysis dated August 5, 2025, each as filed on the System for Electronic Data Analysis and Retrieval + in Canada (SEDAR+) and available on Parkland’s website at http://www.parkland.ca, (iii) in Item 1A of Sunoco’s Annual Report on Form 10-K, filed with the U.S. Securities and Exchange Commission (“SEC”) on February 14, 2025, and (iv) in Item 1A of Sunoco’s Quarterly Reports on Form 10-Q, filed with the SEC on May 8, 2025 and August 7, 2025. Those disclosures are incorporated by reference in this Current Report on Form 8-K. While the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Readers are cautioned not to place undue reliance on this forward-looking information, which is as of the date of this Current Report on Form 8-K. Sunoco and Parkland do not intend to update these statements unless required by the securities laws to do so, and Sunoco and Parkland undertake no obligation to publicly release the result of any revisions to any such forward-looking statements that may be made to reflect events or circumstances after the date of this Current Report on Form 8-K.
