Shares of biopharmaceutical company Baxalta dipped briefly after the bell when it announced a $2.34 billion stock offering. The shares, held by former parent company Baxter International, will be exchanged toward debt with lenders like JPMorgan, Bank of America Merrill Lynch, and Credit Suisse, according to a company statement. After the debt-for-equity exchange, Baxter will hold just over 5 percent of Baxalta, the statement said.
Footwear company Caleres's stock sank despite it reporting earnings that exceeded Wall Street's expectations. The company behind Famous Footwear, Sam Edelman and Naturalizer posted net income of 26 cents a share, the AP reported, higher than the 22 cents per share predicted.
