Check out which companies are making headlines before the bell:
Winnebago — The recreational vehicle maker earned an adjusted 53 cents per share for its latest quarter, 9 cents a share above estimates. Revenue also beat forecasts. Winnebago's results were helped by strong growth in its towable products.
Priceline Group — Barclays upgraded the travel website operator's stock to "overweight" from "equal weight," saying current valuation reflects undue pessimism about the company's prospects.
Adobe Systems — Adobe reported adjusted quarterly earnings of 71 cents per share, 3 cents a share above estimates. The software tools maker's revenue matched forecasts. However, Adobe gave a weaker-than-expected forecast for the current quarter.
FedEx — FedEx beat estimates by 2 cents a share, with adjusted quarterly profit of $3.30 per share. Revenue also came in higher than analysts' forecasts. However, FedEx reported an overall quarterly loss due to pension adjustments and costs related to its acquisition of Europe's TNT.

McDonald's — The restaurant chain has gotten more than six bids for its China and Hong Kong stores, according to Reuters, which said the sale of those stores could bring in up to $3 billion. Separately, Nomura downgraded the stock to "neutral" from "buy," based in part on slowing restaurant same-store sales trends in the U.S.
