Intel — Intel shares dropped 10% after the bell on the back of mixed results for the company's fiscal third quarter. The chip maker reported adjusted earnings per share of $1.11, in line with a Refinitiv estimate. Intel's revenue for the quarter was slightly above expectations. However, sales for the company's Data Center Group came in at $5.91 billion, below a FactSet estimate of $6.21 billion.

Mattel reported earnings per share of 95 cents on revenue of $1.63 billion. Analysts expected a profit of 39 cents per share on revenue of $1.46 billion, according to Refinitiv. The company's results were driven in part by strong sales from its Dolls division.

Robert Half International — Shares of the human resources company ticked higher by 0.3% following the release of stronger-than-forecast quarterly earnings.
