Silicon Labs Slides As Q4 Revenue Guidance Disappoints

Silicon Laboratories (SLAB) shares are trading lower this morning on disappointing Q4 guidance.

For Q3, the chip maker posted revenue of $120.2 million and non-GAAP profits of 53 cents a share; that’s about in line with the Street at $120.4 million and 52 cents.

For Q4, however, the company sees a sequential decline to a range of $105 million to $111 million, falling short of the previous Street consensus of $121.6 million.

“We believe the fourth quarter represents a trough, and the composition of the business that will emerge in 2011 will be even more growth oriented,” CEO Necip Sayiner said in a statement.

SLAB this morning is down $2.27, or 5.8%, to $36.75.
