Preferred Units, Description |  |  |  |  |  |  |  |  |  |  |  |  |  | In September 2025, the Partnership closed a private offering of 1.5 million of its 7.875% Series A Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units (the “Series A Preferred Units”) at an offering price of $1,000 per unit. The Partnership received net proceeds of approximately $1.47 billion from the sale of the Series A Preferred Units after deducting the initial purchasers' discount and other estimated offering expenses. The Partnership used the net proceeds from this private offering (i) on the closing date of the Parkland Acquisition to fund a portion of the cash consideration for the Parkland Acquisition, and (ii) prior to the closing date of the Parkland Acquisition, to temporarily reduce the borrowings outstanding under the Partnership's Credit Facility and to pay interest and fees in connection therewith.Distributions on the Series A Preferred Units will be cumulative from the date of original issuance and will be payable semi-annually in arrears commencing on March 18, 2026, when, as, and if declared by Sunoco GP LLC out of legally available funds for such purpose. An initial distribution on the Series A Preferred Units will be paid on March 18, 2026 in an amount equal to approximately $39.38 per Series A Preferred Unit. |  |
