Valeant Pharmaceuticals — Valeant struck in agreement with loan holders to amend the terms of its debt, according to Dow Jones. The drugmaker's shares are coming off their best two-day percentage gain in 20 years, although they are still down more than 80 percent over the past 12 months.
Costco — The warehouse retailer reported a 1 percent increase in March comparable-store sales, below the consensus Thomson Reuters estimate of a 1.9 percent increase.
Apple — BTIG cut earnings estimates and its price target for Apple, although it is keeping a "buy" rating. BTIG is basing its call on a more conservative outlook for Apple's iPhone upgrade cycle.

ConAgra — The foodmaker reported adjusted quarterly profit of 68 cents per share, 10 cents a share above estimates, while revenue was also above analysts' forecast. A significant increase in profit margins for ConAgra's consumer foods business was among the positive factors for the quarter.
