Check out which companies are making headlines after the bell Wednesday:
Yum Brands - The restaurant chain said its same-store sales tumbled nearly 13 percent for its China division. This included an estimated decline of 16 percent at KFC. Shares dropped in extended-hours trading.
"Within the past week, publicity associated with Avian flu in China has had a significant, negative impact on KFC sales," said the company in an SEC filing. "Historically in these situations, we have educated consumers that properly cooked chicken is perfectly safe to eat, and we will continue to do so. We do not anticipate providing any further updates regarding China Division same-store sales until our scheduled first-quarter earnings release on April 23, 2013."
Bed Bath & Beyond - The retailer posted earnings of $1.68 a share, in line with expectations, while revenue edged past expectations at $3.40 billion versus projections for $3.39 billion. Meanwhile, the company handed in current-quarter earnings estimates that missed Wall Street forecasts but said it expects mid-single digit to low double-digit earnings growth for the full year. Shares climbed in extended-hours trading.
