Check out which companies are making headlines before the bell:

Big Lots–The discount retailer beat estimates by one cent with second quarter earnings of 31 cents per share, excluding certain items. Revenue was below estimates, and a same-store sales increase of 1.7 percent was short of the 2.4 percent consensus forecast. However, Big Lots did raise the lower end of its yearly earnings forecast.

NXP SemiconductorsApple is reportedly working with the Dutch chipmaker on technology to enable pay-by-touch in the next iPhone.

AstraZeneca–The drug maker moved one of its new cancer drugs into a mid-stage study, boosting hopes for its success. The drug currently known as MEDI-4736 is designed to help the body's immune system ward off tumors.

Splunk —The data analytics software maker posted a surprise profit of one cent per share, excluding certain items. Analysts had thought the company would lose two cents per share, and its revenue and forward guidance were also better than expected, as its customer base continues to expand.

Veeva Systems–Veeva beat estimates by two cents with second quarter profit of nine cents per share, excluding certain items. Revenue also beat estimates, with the life-sciences software company saying its sales are running well ahead of its own forecasts.

Pacific Sunwear–The teen retailer matched estimates with a quarterly loss of three cents per share, though revenue and PacSun's same-store sales were better than analysts had forecast. The company had issued a warning back in May about the negative impact of discounting and weakness in its women's division. PacSun also forecast a bigger than expected loss for the current quarter.

Avago Technologies–Avago earned $1.26 per share, excluding certain items, beating estimates by 18 cents. Its revenue nearly doubled from a year earlier, on increasing demand for its smartphone chips.
