About Lonestar Resources US Inc.

Lonestar Resources US Inc. (ticker: LONE) was an independent U.S. oil and natural gas exploration and production company, historically listed on the Nasdaq Global Select Market in the United States before being removed from the public markets following restructuring and a subsequent merger transaction. For equity investors, Lonestar should be viewed as a classic small-cap upstream energy name rather than a diversified oilfield services platform: its business was directly exposed to commodity prices, drilling economics, and regional differentials in U.S. shale. The company was incorporated in Delaware in 2013 and built its operating base in Fort Worth, Texas. SEC disclosures are the clearest source for its corporate history and listing status. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1661920/000110465915087515/a15-25620_11012b.htm?utm_source=openai)) Operationally, Lonestar focused on the exploration, development, production, acquisition, and sale of crude oil, natural gas liquids (NGLs), and natural gas. Its core asset base was centered on the Eagle Ford Shale in South Texas, with older filings also referencing conventional properties in North Texas and Bakken assets in Montana. That profile gave the company a concentrated upstream footprint, meaning performance depended heavily on well productivity, drilling efficiency, and the economics of a single major shale basin rather than a broad multi-basin portfolio.

The company’s strategic strengths were its basin focus and operational flexibility, but those were offset by the usual mid-sized E&P challenges: balance-sheet sensitivity, dependence on hedging and capital discipline, and significant earnings volatility linked to oil and gas price swings. In that sense, Lonestar represented a leveraged way to access U.S. shale exposure, with upside tied to commodity cycles and downside amplified by financial and operational leverage. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1661920/000166192019000075/R7.htm?utm_source=openai)) A key recent milestone was Lonestar’s Chapter 11 filing in 2020, followed by a 2021 acquisition by Penn Virginia Corporation. Penn Virginia later changed its name to Ranger Oil Corporation after completing the transaction, which effectively ended Lonestar’s life as an independent listed company. For investors tracking insider activity or legacy SEC Form 4 references, this historical context matters: any insider transaction record around LONE sits inside a company that was ultimately restructured and absorbed, not a continuing standalone NYSE/Nasdaq issuer.
