EPM

Evolution Petroleum Corporation

An independent energy company based in Houston that buys, develops, and produces onshore oil and natural gas properties across the United States, using techniques like waterflooding to coax more fuel from existing wells. It was founded in 2003 as Natural Gas Systems and took its current name in 2006 through a short-form merger, when a subsidiary called Evolution Petroleum Corporation absorbed the parent company. The ticker symbol EPM has stuck ever since.
