NuStar Energy (US63050T1060) remains tied to Sunoco after the sale of its 24-acre headquarters on September 22, 2026, as Yahoo Finance reported. The property transaction adds a concrete asset event to the story of NSS stock, which is now linked to Sunoco's broader energy infrastructure structure.

Headquarters sale adds a tangible asset

Yahoo Finance reported that Sunoco sold the former NuStar headquarters outside San Antonio to Security Service Federal Credit Union. The site covers 24 acres and includes 319,000 square feet of office space, giving the transaction a measurable operating and real-estate dimension.

The property was assessed at USD 44.0 million, according to the same September 22, 2026 report from Yahoo Finance. For investors tracking the former standalone pipeline operator, the figure separates the headquarters asset from the value of the underlying transportation and storage network.

Sunoco ownership remains the key context

The corporate connection is larger than the property sale. A September 30, 2026 report from IT Boltwise described a USD 7.3 billion transaction involving NuStar Logistics and Sunoco and identified NSS as a New York Stock Exchange security.

The same report compared that figure with Sunoco's USD 6.5 billion stock acquisition of NuStar in June 2024. The USD 0.8 billion difference between the two cited transaction values is a historical comparison, not a current market price, but it shows why NSS is analyzed through Sunoco's ownership structure rather than as a fully independent operating company.

NSS identity and business profile

NSS is listed as NuStar Logistics, L.P. SB NT FX/FL 43 and operates in the energy sector, specifically oil and gas midstream infrastructure. Its business profile centers on pipelines and terminals handling crude oil and refined petroleum products, while the recent headquarters sale shows how the former NuStar platform is being integrated into Sunoco's wider corporate system.
