Check out which companies are making headlines before the bell:
Twitter — Twitter remains on today's watch list amid the continuing speculation that it is moving closer to being sold. Walt Disney and Microsoft are the latest companies to be mentioned as possible Twitter suitors.
Volkswagen — The Justice Department is evaluating how much it could fine the automaker for its diesel emissions scandal without putting it out of business, according to a Bloomberg report.
Kite Pharma — Kite reported upbeat results in a mid-stage clinical trial for its non-Hodgkins lymphoma treatment, with more than 40 percent of patients showing complete remission.
American Express — American Express can bar merchants from steering customers toward other cheaper credit cards from competitors like MasterCard and Visa, according to a ruling from a federal appeals court. That ruling reversed a lower court decision that said AmEx had violated antitrust rules.
JM Smucker — Credit Suisse downgraded the food producer's stock to "neutral" from "outperform," saying it underestimated the level of reinvestment needed to boost the company's pet food division. Credit Suisse said it also underestimated the hit to sales due to difficult comparisons to last year, when an array of new products were launched.
AutoZone — The autoparts retailer was upgraded to "overweight" from "equal-weight" at Morgan Stanley, which pointed to an increase in the number of older vehicles. That traditionally correlates with improved sales of auto parts.
Eli Lilly — The drugmaker was raised to "buy" from "neutral" at Goldman Sachs, citing the potential of significant revenue and earnings growth as well as margin expansion due to its diversified late-stage product pipeline.
Rockwell Collins — Rockwell Collins is partnering with Stellar Labs to develop a cloud-based flight operations management platform. The news is boosting the avionics maker's stock, several days after it announced that Boeing had selected it to provide touchscreen controls for the 777X aircraft.
Boston Scientific — The medical products maker announced the acquisition of EndoChoice Holding for $8 a share, or $210 million in cash. EndoChoice is a maker of imaging systems and other medical technology devices.
FactSet Research Systems — The financial information services provider matched estimates with adjusted quarterly profit of $1.69 per share, but revenue fell below forecasts. FactSet CEO Phil Snow is highlighting the company's ongoing increase in market share.
Carnival Corp. — Carnival is adding to Monday's gains this morning, following the cruise line operator's latest earnings report which saw it both beat Street estimates and raise its full-year forecast.
Wells Fargo — The Labor Department launched what it calls a "top-to-bottom" review off all complaints the department has received in recent years. That follows a congressional hearing last week into the controversy surrounding the bank's sales practices and subsequent settlement with the government.
Autodesk — The company announced a new 30 million share stock buyback program. The new program is in addition to the 1.5 million shares remaining in the software maker's prior buyback program.
Deutsche Bank — The bank's stock remains under pressure, after falling to an all-time low Monday on fears it would have to raise more capital to cover an anticipated $14 billion U.S. fine. The stock slump comes despite reassurances from bank officials that it doesn't anticipate a capital-raising issue and has not asked the German government for any financial assistance.
