Take a look at some of the companies making headlines after the Wednesday's closing bell:

Five Below gained nearly 3 percent in after-hours trading when it reported earnings that beat estimates. The discount retailer, whose goods sell for $1 to $5 each, said in a statement that net sales increased 24.4 percent, to $263.8 million. Comparable-store sales rose by 3.2 percent. The chain ended the quarter with 366 stores in 21 states, an increase of 20 percent from the year-ago period.

Red Hat jumped more than 4 percent in extended-hours trade after reporting a 16 percent jump in quarterly revenue. The world's largest commercial distributor of the Linux operating system said it benefited from increased adoption of open-source software and its cloud-based products. The firm also announced a $500 million share buyback program.

PVH gained in after-hours trade after the owner of apparel brands Tommy Hilfiger and Calvin Klein reported a marginal increase in quarterly sales. However, the firm expects its full-year earnings per share to be negatively affected by the strong dollar and volatility in the global macroeconomic environment.

Verint Systems fell nearly 3 percent in extended-hours trade after slightly lowering guidance for the coming fiscal year. The analytics firm reported quarterly earnings slightly above estimates.

3M shares rose in after-hours trade following news that the firm filed a patent infringement lawsuit in a federal district court in Minnesota on Wednesday against Danville Materials regarding nanofiller technology.
