Texas Instruments posted fourth-quarter earnings that beat analyst estimates, but its guidance for the first quarter was below estimates.

The chip maker expects to earn 24 to 32 cents per share in the first quarter, below Street estimates for 34 cents per share, as the company exits the wireless business. Revenue is expected to be between $2.69 billion to $2.91 billion compared with a forecast of $2.89 billion, according to a consensus estimate from Thomson Reuters.
