About Cimarex Energy Co

CIMAREX ENERGY CO. (ticker XEC) was historically a U.S. independent oil and gas exploration and production company listed on the NYSE. For investors, the critical point is that Cimarex no longer exists as a standalone public company: it was formed in 2002, spun out of Helmerich & Payne, and then became part of the transaction that ultimately created Coterra Energy after Cimarex merged with Cabot Oil & Gas in 2021. SEC filings describe Cimarex as a Delaware corporation formed in 2002, with historical headquarters in Denver, Colorado, United States. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1168054/000110465906015366/a06-1998_110k.htm?utm_source=openai)) Operationally, Cimarex was an upstream E&P business focused on the exploration, development and production of hydrocarbons, especially crude oil, natural gas and natural gas liquids. Its operations were entirely located in the United States according to its SEC disclosures, with a portfolio concentrated in onshore basins and shale-related acreage. Over time, the company built exposure across key producing regions such as Texas, New Mexico and Oklahoma, and at various points highlighted the Delaware Basin as a meaningful part of its footprint. This geographic concentration in U.S. domestic basins gave the company a clear operating focus and relatively direct leverage to North American commodity pricing.

Its investment case centered on capital efficiency, reserve replacement and cash generation from a portfolio of liquids and gas assets. The company also pursued portfolio growth through acquisitions, including the announced purchase of Resolute Energy in 2018, which expanded its acreage in Reeves County. That strategic path culminated in the 2021 merger with Cabot Oil & Gas, a transaction that combined complementary oil and gas portfolios and led to the rebranding of the combined company as Coterra Energy.

Any recent SEC insider-transaction or Form 4 references to XEC should therefore be interpreted in a historical or legacy-data context. The economically relevant “current” company is Coterra Energy, which inherited the combined asset base after the merger. In short, Cimarex’s story is one of U.S. shale-era consolidation: a Denver-based upstream producer founded in 2002, active exclusively in the United States, and ultimately absorbed into a larger listed energy platform.
