The Nasdaq-listed company, which is being taken over by its UK rival Amec in a $3.3bn (£1.95bn) deal announced earlier this year, said separately that its shareholders have approved a one-time dividend of $0.40 per share, which will be paid out on 21 May.
Adjusted income for the first quarter of 2014 was $19.1m, equating to earnings per share of $0.19, compared with adjusted earnings of $18.9m in the same quarter the previous year. Analysts had estimated earnings of $0.38 per share.
The results were also below the average quarter of last year, due to a 17 per cent drop in operating earnings and a higher tax rate.
“The company’s first-quarter adjusted income was well below what we would expect to see as a quarterly run rate in 2014, a year in which we anticipate that the company’s performance will be driven by sequential-year growth in scope revenues in both of our business groups,” said chief Kent Masters. Shares closed up at $34.34.
