This Atlanta-based provider of services and equipment for the oil and natural gas industry lost money in 2009, but steadily increased revenues in the three years that followed. RPC was buoyed in 2012 by high oil prices, which drove business for the firm in North Dakota and South Texas. Increases in oil drilling came as RPC’s natural gas business fell off, largely due to low prices and a decline in drilling among the company’s customers. The low price of natural gas has continued to hurt RPC in 2013. In the second quarter, RPC made $67.9 million on revenues of $457.6 million, a 43.4% drop in profits compared to the same period a year ago. --C.G.
