Shares of RPC Inc. tumbled 10% in morning trade Wednesday, enough to pace all NYSE decliners, after the oil and gas services company slashed its dividend in half and missed first-quarter earnings and revenue expectations. The company said the new dividend of 5 cents a share, down from 10 cents, will be payable June 10 to shareholders of record on May 10. "In light of the uncertainty in the oilfield market, this reduced dividend strengthens our capital structure and enhances our ability to maintain a conservative balance sheet," RPC said in a statement. The dividend cuts lowers the implied dividend yield to 1.74% from 3.48%, compared with the implied yield for the S&P 500 of 1.95%. Separately, the company reported a first-quarter net loss of $739,000, or $0.00 on a per-share basis, compared with earnings of $13.4 million, or 6 cents a share, a year ago, as revenue fell to $334.7 million from $376.8 million amid lower pricing and activity levels. The FactSet consensus was for earnings per share of 3 cents and revenue of $350.4 million. Cost of revenue increased to 75.4% of revenue from 67.7% or revenue a year ago. The stock has shed 38% over the past 12 months, while the VanEck Oil Services ETF has lost 32% and the S&P 500 has gained 11%.
