Check out which companies are making headlines before the bell:
Fiat Chrysler Automobiles (FCAU)—The stock makes its Wall Street debut today, marking the return of a Chrysler-related stock to the U.S. market. Chrysler traded under its own name until 1998, when it was sold to Mercedes parent Daimler. It was then sold to Cerberus Capital Management in 2007, followed by a 2009 bankruptcy filing and Fiat's first purchase of a stake in 2011.
Danaher —The company will combine its communications business with NetScout in a tax-free transaction. Danaher shareholders will receive about 60 percent of NetScout's shares once the transaction is complete.
J.C. Penney—The retailer's shares were downgraded to "sell" from "neutral" at UBS, which said the company's earnings targets were too optimistic and that Penney is not debuting enough new merchandise.
