Schlumberger - The oilfield-services company reported first-quarter profit of $0.98 per share, excluding certain items, one cent above estimates. Profits were up 38 percent from a year earlier as Schlumberger's customers ramped up production and exploration in areas like the Gulf of Mexico.

Microsoft - The software giant earned 60 cents per share for its fiscal third quarter, three cents above estimates, with revenue also beating consensus. Microsoft's results were helped by better-than-expected overall personal computer sales during the quarter.

Chipotle Mexican Grill - The restaurant chain reported first-quarter profit of $1.97 vs. Street estimates of $1.93, and also reported better-than-expected revenue. Chipotle's same-store sales topped analyst forecasts, and the bottom line was also helped by menu price increases instituted in 2011.

Advanced Micro Devices - The chipmaker earned $0.12 per share for its first quarter, three cents above estimates. Revenue registered a slight beat, as AMD joined Microsoft in benefiting from better-than-expected PC demand.

Capital One - The bank and credit-card issuer beat estimates by 17 cents with its first quarter profit of $1.56 per share. Revenue of $4.9 billion was above the consensus estimate of $4.37 billion, on better-than-anticipated loan volume.
