NuStar Energy L.P. Stock: price and insider trades · United States

NuStar Energy L.P. (NYSE: NS) was a U.S.-based energy infrastructure partnership focused on the transportation, storage, and terminaling of petroleum products and specialty liquids. Headquartered in San Antonio, Texas, United States, NuStar operated as a master limited partnership listed on the NYSE. Its modern corporate history dates to 2007, when Valero L.P. adopted the NuStar Energy L.P. name following its separation from Valero Energy Corporation. Over time, NuStar expanded through acquisitions and capital projects, building a larger network of pipelines, terminals, and selected asphalt-related assets.

From an operating perspective, NuStar’s business model was built around complementary midstream assets. Its core activities included crude oil and refined-product pipelines, storage and terminal facilities, and, historically, asphalt refining and marketing operations. The strategic appeal of this model was the combination of asset-backed, fee-oriented infrastructure revenues with exposure to key U.S. energy corridors, coastal demand centers, and export-linked logistics. In practice, NuStar positioned itself as an important independent operator in the liquids terminal and pipeline space across the United States, competing with both large integrated energy groups and other midstream specialists.
