Check out which companies are making headlines before the bell:

First Solar — Goldman Sachs upgraded the solar equipment maker's stock to "buy" from "neutral" and increased its target price to $100 per share from $60. Goldman considers First Solar one of its top ideas for 2016 and offers the most substantial upside in the sector over the next 12 months, citing a "best-in-class balance sheet" and added production capacity.
Willis Towers Watson — Towers Watson and Willis Group Holdings have successfully completed their merger, with the consulting firm beginning combined operations and trading under its new name and ticker symbol ("WLTW").
