Schlumberger rises after long-term profit guidance beats expectations
Schlumberger (SLB) and its peers are rising after the oil and gas services company provided long-term profit guidance. WHAT'S NEW: At an investor conference earlier today, Schlumberger predicted that its earnings per share would increase at a compound annual growth rate of 17%-20%. In a note to investors earlier today, RBC Capital analyst Kurt Hallead wrote that the Street was expecting the company's EPS to grow at an annualized rate of 15%. Schlumberger predicted that its 2017 EPS would be $9-$10. The company said it could achieve its guidance through revenue growth, margin expansion, and share repurchases. Sclhumberger added that it expects oil markets to be "well-balanced" through 2017. It predicted that spending on exploration would be "subdued" in 2015, but it expects a renewed focus on exploration in 2016-2017. WHAT'S NOTABLE: Before Schlumberger announced its guidance today, Hallead predicted that the company's EPS would reach $8 in 2016. He kept an Outperform rating on the shares.
