Check out which companies are making headlines before the bell:
General Electric — The company reported adjusted first quarter profit of 21 cents per share, 2 cents a share above estimates, while revenue was essentially in line. However, investors are expressing concern about a 1 percent drop in organic revenue.
Caterpillar — Caterpillar earned an adjusted 67 cents per share for the first quarter, 1 cent a share below estimates, while revenue beat forecasts. The heavy equipment maker did lower the midpoint of its 2016 sales outlook, on the continuing slump in demand.
Carnival — The cruise line's Fathom brand announced it would begin cruises to Cuba on May 1.
Honeywell — Honeywell came in 3 cents a share above estimates with profit of $1.53 per share, while revenue also beat forecasts. The industrial products maker also raised the low end of its 2016 full-year earnings target.
SunTrust Banks — The bank reported quarterly profit of 84 cents per share, 9 cents above estimates, and revenue also beat analysts' projections. SunTrust was helped by an increase in interest income.
AutoNation — The auto retailer missed estimates by 3 cents a share with adjusted quarterly profit of 90 cents per share, with revenue also missing. AutoNation was impacted by storms in Texas late in the quarter as well as higher costs for deal incentives.
Alphabet — The Google parent reported adjusted quarterly profit of $7.50 per share, short of the $7.97 a share consensus estimate. Revenue also missed forecasts, as the company increased its investments in new projects.
Microsoft — Microsoft earned an adjusted 62 cents per share for its latest quarter, 2 cents a share shy of forecasts, with revenue for the software giant essentially in line with estimates. Microsoft is being hurt by continued weakness in the personal computer market even as it grows its newer businesses.
Starbucks — Starbucks matched estimates with quarterly profit of 39 cents per share, with revenue just slightly shy of consensus forecasts. That revenue miss is weighing on shares despite increased mobile business and higher domestic demand.
Visa — Visa came in 1 cent a share above estimates with adjusted quarterly profit of 68 cents per share, while revenue was slightly above forecasts. The credit card issuer did lower its full-year revenue growth forecast, saying it is not seeing material improvements in economic trends and that cross border spending has been weak.
Schlumberger — Schlumberger reported adjusted quarterly profit of 40 cents per share, a penny a share above estimates, with revenue essentially in line. The oilfield services company did see profit cut by nearly half compared to a year earlier as oil prices dropped, but that fall was cushioned by cost cuts.
Norfolk Southern — Norfolk Southern trounced estimates by 32 cents with quarterly profit of $1.29 per share, while the railroad operator's revenue also came in above forecasts. Cost cuts and other streamlining measures helped the company's results, amid a 6 percent decline in freight volume.
Hanesbrands — Hanesbrands beat estimates by 4 cents a share with adjusted quarterly profit of 26 cents per share, with revenue slightly above consensus forecasts. The apparel maker was helped by better activewear sales and savings from acquisitions.
Advanced Micro Devices — AMD lost 12 cents per share, 1 cent a share less than analysts had been expecting. The chipmaker's revenue exceeded forecasts, and it also sees extremely strong current-quarter revenue.
Boston Beer — Earnings fell substantially short of Street forecasts, with quarterly profit of 53 cents per share compared to the 96 cent a share consensus estimate. The beer brewer's revenue also fell short, as does its latest fiscal year forecast. Increasing competition for the brewer of Sam Adams beer has hurt the company's results.
Skechers — The company saw its quarterly results come in 9 cents a share above estimates at 63 cents per share, and the shoe maker's revenue was well above estimates, as well. Its results were helped by international growth, although its current-quarter revenue projection is less than analysts had been expecting.
Sears — Sears will close 78 Sears and Kmart stores over the next few months, amounting to about 5 percent of its current stores. The retailer has been moving to shrink its operations, and had said in February it was seeking faster staff cuts and store closings.
Charles Schwab — The discount broker raised its quarterly dividend by 1 cent a share to 7 cents per share, payable on May 27 to shareholders of record as of May 13.
Volkswagen — The automaker has increased its provision for costs related to its emissions scandal to up to $19.2 billion, according to Reuters, nearly three times its prior provision.
Sony — Sony is delaying its earnings forecasts while it assess the impact of recent earthquakes on its sensor image plant in southern Japan.
