Xilinx CEO Victor Peng

Xilinx (XLNX - Get Report) shares were lower after hours Wednesday, after the chipmaker reported fiscal-first-quarter results that exceeded expectations, but gave weaker-than-expected revenue guidance for its current quarter.

The stock was trading 5.6% down at $124.69.

For the quarter ended June 29, Xilinx earned 94 cents a share, up 27% from 74 cents in the year-earlier period, on revenue of $849.6 million. Those figures beat analyst estimates of earnings of 93 cents a share and revenue of $847.4 million, according to FactSet.

On an adjusted basis, earnings of 97 cents per share beat estimates of 95 cents

For the fiscal second quarter, however, Xilinx expects revenue of between $800 million to $850 million, lower than consensus estimates of $853 million. The company said its gross-profit margin should come in at 65% to 66%.
