NXP (NASDAQ:NXPI) +4.3% after beating Q1 estimates and issuing healthy guidance. The chipmaker expects Q2 revenue of $1.12B-$1.18B and EPS of $0..62-$0.70, generally favorable to a consensus of $1.14B and $0.62. A 60% Y/Y increase in identification chip sales to $300M (now 28% of revenue, fueled by NFC chips) contributed to the beat. 20% Y/Y growth for high-performance mixed signal chips also didn't hurt. Portable & Computing (PC/mobile chips) was a weak spot, declining 12% Q/Q (though up 9% Y/Y). Gross margin rose to 50% from Q4's 46% and Q1 2012's 44%, and buybacks totaled $35M. Opex rose 1%, well below rev. growth of 15%. (PR)
