Check out the companies making headlines after the bell Monday:
Kohl's stock dropped after the bell on the first trading day of 2016. The apparel retailer fell 22 percent over the course of 2015, and analysts are expecting another disappointing year for department store chains like Kohl's.
Baxalta stock inched slightly higher in after-hours trading. The drugmaker jumped more than 5 percent in the regular session after inking a deal with privately held Symphogen. The potentially $1.6 billion deal allows both companies to develop immuno-oncology drugs to treat rare cancers.
