Check out which companies are making headlines before the bell:
Apple—The company beat estimates by a wide margin with the biggest quarterly profit in corporate history. Apple earned $3.06 per share for its latest quarter, 46 cents above estimates, with revenue swamping forecasts as well. The quarterly was led by record sales of iPhone 6 and iPhone 6 Plus models during the holiday season.
Arm Holdings—The chip maker is seeing its shares rise this morning, along with other companies that supply parts to Apple. Arm is a provider of graphics processing chips.
Boeing—The jet maker reported adjusted quarterly profit of $2.31 per share, 20 cents above estimates. Revenue was also above estimates, although its earnings per share guidance of $8.20 to $8.40 is below estimates of $8.64. Boeing also expects 2015 commercial jet deliveries of 750 to 755, above 2014's 723.
Textron—The maker of Bell Helicopters and Cessna jets matched estimates with fourth quarter profit of 76 cents per share, while revenue fell below consensus. Amid slack demand, Textron's full-year outlook falls below current analyst estimates.
McCormick—The spice maker beat estimates by 2 cents with adjusted fourth quarter profit of $1.16 per share. However, revenue was below forecasts, as is the company's 2015 full year forecast. The company said a strong dollar is weighing on the value of its international sales.
General Dynamics—The defense contractor beat estimates by 6 cents with adjusted quarterly profit of $2.19 per share, with revenue also beating analyst forecasts. The profit rise was driven by a jump in aircraft orders.
AmerisourceBergen—The drug wholesaler reported fiscal first quarter profit of $1.14 per share on an adjusted basis, well above the 97 cents consensus estimate. Revenue also beat estimates by a healthy margin, while gross margins increased.
Tupperware Brands—The household products maker scored a 10 cent beat with fourth quarter profit of $1.63 per share, with revenue also above consensus. However, Tupperware is forecasting a bigger-than-expected decline in the current quarter and a weaker-than-expected profit forecast for the year.
AT&T—The telecommunications company earned an adjusted 55 cents per share for its latest quarter, 1 cent above estimates, with revenue scoring a slight beat as well. It added 54,000 wireless customers during the quarter, although the rate of customer defections is rising as well.
Amgen—The drug maker beat estimates by 11 cents with adjusted quarterly profit of $2.16 per share, with revenue also above consensus. Amgen's results were helped by strong sales of its Enbrel treatment for rheumatoid arthritis.
Yahoo—The company will spin off its 15-percent stake in Alibaba into a separate company in a tax-free transaction. Separately, Yahoo reported adjusted quarterly profit of 30 cents per share, 1 cent above estimates, with revenue roughly in line.

Juniper Networks—The maker of networking equipment earned an adjusted 41 cents per share for its fourth quarter, 10 cents above estimates, with revenue edging above Street forecasts as well. Juniper said it saw a "challenging" revenue environment for the first half of 2015, although it did give a more upbeat long-term outlook.
Stryker—The maker of medical devices fell a penny short of estimates with adjusted quarterly profit of $1.44 per share, while revenue was in line. Stryker saw its profit hurt by higher recall costs and the impact of foreign exchange rates.
Western Digital—The maker of hard disk drives reported adjusted quarterly profit of $2.26 per share, 16 cents above estimates, while revenue was slightly above consensus. Western Digital benefited from lower expenses.
VMWare—The software maker beat estimates by a penny with adjusted quarterly profit of $1.08 per share, while revenue was essentially in line. VMWare saw strong demand for its cloud-related products, and it also announced it is doubling its share buyback program to $2 billion. However, it also gave weaker-than-expected revenue guidance.
