Check out which companies are making headlines before the bell:
Regions Financial — The regional bank beat estimates by 1 cent with quarterly profit of 20 cents per share, while revenue was above forecasts as well. The company said it is seeing some success at generating new sources of revenue while controlling its costs.
Polycom — The voice and video services company agreed to be bought by mobile technology company Mitel for about $2 billion in cash and stock, or $13.65 per share. That's about 11 percent above Polycom's Thursday closing price.
Bats Global Markets — The exchange operator makes its second attempt at an initial public offering, pricing its IPO at $19 per share, at the high end of the expected range and raising $253 million. The first IPO attempt in 2012 was waylaid by technical issues.
Foot Locker — Cowen downgraded the athletic footwear and apparel maker to "market perform" from "outperform," based in part on expected increased promotional activity for Nike products. That could weight on Foot Locker's comparable store sales.
Micron Technology — Brean initiated coverage on the chipmaker's shares with a "buy" rating, saying Micron is well-positioned to take advantage of long term trends in the memory chip market.
SeaWorld Entertainment — Citi downgraded the theme park operator to "neutral" from "buy," following a recent run-up in the stock after management's change in strategy. Citi points out that SeaWorld has been losing market share to peers in recent years, particularly Universal.
Costco — The warehouse retailer raised its quarterly dividend to 45 cents per share from 40 cents, a 12.5 percent increase. The dividend is payable on May 13 to shareholders of record as of April 29.
Volkswagen — The automaker posted its 16th monthly sales drop in 18 months, although the pace of the drop slowed to 2.7 percent from February's 4.7 percent.
Viacom — Controlling shareholder Sumner Redstone will not be deposed and will not give testimony at his upcoming mental competency trial, according to a judge's ruling.
Apple — Apple component suppliers Taiwan Semiconductor and Largan Precision issued weak second quarter revenue forecasts, casting some doubt on demand for Apple products. Apple will release its own quarterly numbers on April 25.
Goldman Sachs — Goldman is heavily cutting costs, according to a Bloomberg story that said the company is cutting support staff and increasingly rejecting travel and entertainment expenses.
Yahoo — Yahoo is making it difficult for possible bidders for its assets to actually decide whether to do so, according to a New York Times DealBook story. Yahoo is said to be refusing to discuss prospects for 2017 or answer other important questions.
Dick's Sporting Goods — Dick's is among the bidders for some of rival Sports Authority's assets that are being sold at a bankruptcy auction, according to Reuters. Academy Sports, owned by private equity firm KKR, is also said to be among the bidders, while family-owned Modell's is still deciding whether to participate.
