Check out which companies are making headlines before the bell:
Boeing — The jetmaker earned an adjusted $1.60 per share for the fourth quarter, 32 cents above estimates, with revenue also above forecasts. However, Boeing's 2016 full-year forecast is shy of Street forecasts.
United Technologies — The company reported adjusted quarterly profit of $1.53 per share, beating estimates by 1 cent. However, revenue was shy of estimates, owing in large part to the negative effects of a stronger dollar.
Tupperware — The maker of household storage products missed estimates by 3 cents with adjusted profit of $1.38 per share, with revenue also short of estimates. The company also sees 2016 profit below Street forecasts, as it battles what it calls economic and political headwinds.
Fiat Chrysler — The automaker is taking a $906 million charge related to changes in its North American production schedule, with full details to be released later today.
Anthem — The health insurer earned an adjusted $1.14 per share for its latest quarter, missing estimates by 6 cents, though its revenue beat forecasts. Anthem said it had positive operating momentum heading into 2016, with more people enrolling in its Medicaid plans, and that it will be enhanced by the impending acquisition of Cigna.
Fitbit — Citi began coverage on the wearable fitness products maker with a "buy/high risk" rating, saying the company should benefit from a new product cycle later this year despite a tepid reception for its "Blaze" smartwatch introduced earlier this month.
Apple — Apple investors are focusing on the slowest growth for iPhone sales since the phone was introduced in 2007. In its quarterly earnings release, Apple also forecast the first revenue decline in 13 years. For its latest quarter, Apple did beat estimates by 5 cents with profit of $3.28 per share, though revenue was below forecasts.
AT&T — AT&T matched estimates with adjusted quarterly profit of 63 cents per share, but revenue fell short of estimates. AT&T has been hit by growing competition in the wireless area, with fewer subscriber additions than it saw a year earlier.
Capital One — Capital One earned $1.58 per share for its latest quarter, missing estimates by 3 cents, though revenue was slightly above forecasts. The credit card issuer was hurt by higher marketing and operating costs.
Citizens Financial — Citizens Financial will join the S&P 500 at the close of business on Friday. The banking company will replace Precision Castparts, which is being bought by Warren Buffett's Berkshire Hathaway.
VMWare — VMWare earned an adjusted $1.26 per share for its latest quarter, 1 cent above estimates, with revenue slightly above forecasts. The software company will also take a restructuring charge of up to $65 million as it eliminates about 800 jobs, and it also announced CFO Jonathan Chadwick is leaving the company.
U.S. Steel — The company reported an adjusted loss of 23 cents per share, much smaller than the expected loss of 83 cents. The steelmaker did say it faces "significant headwinds" for this year, amid an abundance of supply and competition from lower-priced imports.
Wells Fargo — The bank added 350 million shares to its stock buyback program, worth nearly $17 billion at current prices.
Novartis — Novartis reported a 57 percent decline in quarterly profit, hurt by poor performance in its Alcon eye-care business. The Swiss drug maker outlined plans to improve that unit's performance.
Ericsson — Ericsson reported better than expected quarterly profit, as the telecom equipment maker's China business rebounded.
Quantum Corporation — Quantum saw activist investor Starboard Value sell five million shares of the storage and data protection company. Starboard had held about 25.6 million Quantum shares as of its most recent Securities and Exchange Commission filing.
