Deal Day! ExxonMobil closes Pioneer Resources acquisition, Sunoco closes NuStar Energy

A lot of energy-industry M&A activity lately has been focused on the acquiring company gaining scale in a shale play or region where it’s already very active, usually the Permian. The latest multibillion-dollar deal in the energy space is different: Sunoco LP (stock ticker symbol SUN), which is primarily involved in fuel distribution east of the Mississippi and in Texas, is buying NuStar Energy (ticker NS), a midstream company with a mix of pipelines (crude oil, products and ammonia) and terminals, most of them within the U.S.’s midsection. As we discuss in today’s RBN blog, the combined company will have a massive footprint, with all kinds of opportunities for synergies and growth. 

Sometimes, courtship is better the second time around. After some previous rumors and flirting with a deal in the spring of 2023, ExxonMobil, the largest international integrated oil company, reached an agreement to acquire Pioneer Natural Resources, the largest pure-play Permian producer, for $64.5 billion, the largest-ever U.S. upstream transaction. In today’s blog, we analyze the deal that would make ExxonMobil the top Permian producer, including shifts in the focus and depth of its upstream portfolio, the integration with its existing midstream and downstream infrastructure, and its energy transition goals.

For a major oil and gas producer, organic growth over time is all well and good. But if you want next-level scale — and the economies that come with it — there’s nothing like cannon-balling into the deep end of the pool with a huge, game-changing acquisition. ExxonMobil has already done that twice — first in 2010 with the $41 billion purchase of XTO Energy, then in 2017 when it bought the Bass family’s oil and gas assets for $6.6 billion. Now it’s said to be poised for another big plunge, and to be eyeing the Permian’s largest E&P, Pioneer Natural Resources. In today’s RBN blog, we analyze a potential deal that would make Exxon the dominant producer in the premier U.S. shale play.
