Take a look at some of the companies making headlines after the bell:

CSX gained nearly 3 percent in extended-hours trade after reporting earnings that beat on both the top and bottom lines. The railroad operator reported revenue of $3 billion for the quarter, driven by market growth and the ability to charge higher prices.

Intel traded up more than 2 percent in the after-hours when the chipmaker forecast a 3 percent jump in current-quarter revenue. The firm expects to benefit from gains in its personal computer chips and its data center business. However, the tech company reported quarterly results that were in-line with estimates on revenue that slightly missed expectations.

Pinnacle Entertainment rose more than 2.5 percent in extended-hours trade on a Dow Jones report that Gaming and Leisure Properties raised its bid for Pinnacle's real estate holdings. The real estate investment trust for casino properties fell more than 1 percent in after-hours trade.

Starwood Property Trust fell nearly 2 percent in extended trade after announcing it would offer 12 million shares. The firm said it plans to use the funds to purchase additional commercial mortgage loans, including funding of some properties in Dublin, Ireland.

Biogen shares gained more than 2 percent in after-hours trade following positive results in a drug study.
