* Shares up 9 percent May 7 (Reuters) - Rowan Cos Inc's (RDC.N) first-quarter profit rose 34 percent, boosted by higher drilling revenue, but said weakening demand for drilling services and equipment continued to pressure revenue.
"While all of our jack-ups are under contract today, we are likely to have idle time on jack-ups in both the Gulf of Mexico and the Middle East in the near future," Chief Executive Matt Ralls said in a statement.
First quarter net income was $131.7 million, or $1.16 a share, including 2 cents a share gain related to asset disposals. The company earned $98.6 million, or 88 cents a share, a year earlier.
Selling, general and administrative expenses dropped 10 percent to $24.6 million.
Revenue at the company grew marginally to $494.8 million. Revenue at its drilling operations segment rose 12 percent to $380.4 million, while its manufacturing operations unit revenue rose 29 percent to $187.9 million. [ID:nWNAB5404]
