Check out which companies are making headlines before the bell:
PepsiCo — The snack and beverage giant matched estimates with adjusted quarterly profit of $1.06 per share. Revenue beat forecasts despite the negative impact of a strong dollar, and Pepsi made upbeat comments about the current year despite a "challenging" environment. It also increased its annual dividend to $3.01 per share from $2.81.
Nielsen — The ratings company came in 2 cents above estimates with adjusted quarterly profit of 82 cents per share, with revenue scoring a beat as well. The company said it benefited from the rollout of new products as well as winning new clients.
Avon Products — The cosmetics maker reported a breakeven quarter, missing estimates by 8 cents, with revenue also below forecasts as sales fell for a 16th straight quarter. Avon was hurt by continuing declines in its key Latin American market.
Twitter — Twitter reported adjusted quarterly profit of 16 cents per share, 4 cents above estimates, with revenue matching forecasts. However, Twitter shares are under pressure as the key metric of monthly average users posted a decline, and the company gave current quarter revenue guidance that falls below Street forecasts.
Tesla — Tesla lost 87 cents per share for its latest quarter, compared to forecasts of a 10 cent per share profit, with revenue slightly below forecasts. However, the automaker gave a forecast for deliveries of its Model X that topped analyst estimates, and also said it expected to be profitable this year.
Time Inc. — The magazine publisher missed estimates by 8 cents with adjusted quarterly profit of 58 cents per share, though revenue exceeded forecasts. Time did make upbeat comments about 2016 revenue, predicting growth after a 2015 decline.
TripAdvisor — The travel website operator reported adjusted quarterly profit of 45 cents per share, 12 cents above estimates, and revenue was also well above Street consensus. TripAdvisor benefited from higher ad sales and an increase in subscriptions.
SolarCity — The solar equipment maker's Chief Financial Officer Brad Buss resigned, replaced by SolarCity President Tanguy Serra.
Amazon.com — Amazon announced a $5 billion stock buyback program, replacing a $2 billion program that had been announced in 2010 and had $763 million remaining.
Whole Foods — Whole Foods came in 6 cents above estimates with quarterly profit of 46 cents per share, while the grocery chain's revenue was slightly above forecasts. The company also forecast fiscal 2016 comparable sales would fall into a range of down 2 percent to flat.
Expedia — Expedia missed forecasts by 23 cents with adjusted quarterly profit of 77 cents per share, with revenue roughly in line. The travel website operator did give an upbeat 2016 profit forecast.
Zynga — Zynga matched analyst forecasts by reporting a breakeven quarter, but its current quarter forecast comes in below projections. The creator of the "Farmville" online game expects to release just one new game in the current quarter, pressuring its results.
Yahoo — Yahoo announced the first round of layoffs in its planned move to eventually trim 15 percent of its workforce. 107 employees will be laid off as of April 11. (Disclosure: CNBC has a content-sharing partnership with Yahoo's finance site.)
UPS — UPS increased its quarterly dividend to 78 cents per share from 73 cents, and also named CEO David Abney as its chairman, replacing former CEO Scott Davis in that position.
Cisco Systems — Cisco reported adjusted quarterly profit of 57 cents per share, 3 cents above estimates, while revenue came in slightly above Street consensus. The networking equipment maker also increased its quarterly dividend to 26 cents per share from 21 cents, and increased its stock buyback program by $15 billion.
iRobot — iRobot beat estimates by 8 cents with quarterly earnings of 65 cents per share, while the vacuum cleaner's revenue also exceeded forecasts. But iRobot's current quarter guidance is below estimates, as is its full-year forecast.
Skechers — Skechers saw earnings miss by a penny at 19 cents per share, but revenue for the footwear maker's latest quarter was well above forecasts. The company also said 2016 sales were off to a strong start and that comparable sales are growing in the mid-to-high single digit range.
Pilgrim's Pride — Pilgrim's Pride earned an adjusted 26 cents per share for its latest quarter, falling 14 cents shy of estimates, with revenue slightly below forecasts. The poultry producer's results were impacted by a bird flu outbreak that led to export restrictions.
Mylan — Mylan is buying Swedish drug maker Meda For $7.2 billion in cash in stock. Separately, Mylan also reported quarterly profit of $1.22 per share on an adjusted basis, falling 6 cents below estimates.
Rio Tinto — The company scrapped its policy of never cutting its dividend payout from year to year, because of a challenging environment for the mining company.
Nokia — Nokia reported a better than expected profit for its latest quarter, but the telecom equipment maker warned of a negative impact from a slowdown in the key China market.
Boeing — Boeing will cut jobs at its commercial airplane unit, in an effort to cut costs and better compete with Europe's Airbus.
KeyCorp — KeyCorp's deal to buy rival regional bank First Niagara would be rejected by federal regulators if New York Governor Andrew Cuomo has his way. He is urging that the deal be blocked, saying it would cost thousands of jobs and reduce retail banking competition.
