Exhibit 99.1

Sunoco LP Completes Acquisition of NuStar Energy L.P.;

Announces a 4% Increase in Quarterly Distribution

DALLAS, May 3, 2024 – Sunoco LP (NYSE: SUN) (“Sunoco”) announced the completion of the acquisition of NuStar Energy L.P. (“NuStar”) and a 4% increase in its quarterly distribution.

NuStar Energy Acquisition

Sunoco announced the completion of the acquisition of NuStar. The merger was approved by NuStar unitholders at its Special Meeting held on May 1, 2024. Effective as of the opening of markets on May 3, 2024, NuStar’s common units ceased trading on the New York Stock Exchange.

The completion of this transaction increases Sunoco’s stability and credit profile, strengthens its financial foundation, and enhances its ability to grow. Sunoco expects to realize at least $150 million of expense and commercial synergies. In addition, Sunoco expects at least $50 million per year of additional cash flow from refinancing activity. Sunoco expects the transaction to be immediately accretive to distributable cash flow per LP unit, growing to greater than 10% accretion by the third year following close.

Quarterly Distribution Increase

Sunoco also announced that the Board of Directors of its general partner declared a quarterly distribution for the first quarter of 2024 of $0.8756 per common unit or $3.5024 per common unit on an annualized basis. The distribution will be paid on May 20, 2024, to common unitholders of record on May 13, 2024 (including the former NuStar unitholders who received Sunoco common units upon the completion of the merger).

Building on the 2% increase last year, this 4% increase demonstrates Sunoco’s continued confidence in the business and in future distribution increases.

Sunoco will provide additional details about the NuStar acquisition and distribution increase on Sunoco’s first quarter 2024 conference call on May 8, 2024, at 9:00 a.m. Central Daylight Time.
