Ensign Energy Services (ESI.TO) Stock Analysis & Winston Score
Ensign Energy Services is a Canadian company that drills oil and gas wells for energy producers. It operates large drilling rigs that bore deep into the ground so that oil and gas companies can extract fossil fuels. Its main customers are exploration and production companies in Canada, the United States, and international markets including Australia and the Middle East. Ensign makes money by charging customers a daily rate to use its drilling rigs and crews. It is one of the larger contract drillers in North America, with a fleet of over 200 rigs. The company carries a significant debt load, which makes it vulnerable when oil prices fall and customers cut drilling budgets. Its thin margins — as shown by a gross margin below 6% — reflect how competitive and capital-intensive the contract drilling business is. The key risk going forward is that prolonged low oil prices or an energy transition away from fossil fuels could reduce demand for its services.
