Texas Instruments – Texas Instruments' stock fell 1% in extended trading on Wednesday after the company said its revenues declined in the fourth quarter and may do so against in the current three-month period. The semiconductor company did beat estimates, reporting earnings of $1.11 per share on revenue of $3.35 billion, while analysts expected earnings of $1.02 per share on revenue of $3.22 billion, according to Refinitiv. However, revenue decreased 10% from the same quarter a year ago, and the midpoint of its first-quarter guidance is about 9% below the first quarter of 2019.
