Check out which companies are making headlines before the bell:
Corrections Corporation of America — The prison operator said it was "disappointed" in the Justice Department's recommendation that the Federal Bureau of Prisons reduce reliance on privately operated prison facilities. The stock plunged about 35 percent Thursday on nearly 28 times this month's average daily volume.
Hibbett Sports — The sporting goods retailer earned 29 cents per share for its latest quarter, 2 cents a share above estimates. Revenue was short of analysts' projections, however. Hibbett is seeing particular strength in footwear and also said it might see a slight improvement in profit margins for the year.
Deere — The farm equipment maker earned $1.55 per share for its latest quarter, well above estimates of 94 cents a share. Revenue was slightly below forecasts, but Deere raised its full-year profit forecast by more than it had cut it back in May. Deere was able to draw higher prices and also benefited from cutting costs.
Foot Locker — The athletic apparel and footwear retailer earned 94 cents per share for the second quarter, beating estimates by 4 cents a share. Revenue beat forecasts, as well. Foot Locker also saw a better-than-expected 4.7 percent increase in same-store sales.
Estee Lauder — The cosmetics maker reported adjusted quarterly profit of 43 cents per share, 3 cents a share above estimates. Revenue was essentially in line with estimates. Estee Lauder's bottom line was helped by stronger sales of its various makeup products.
Gap — The apparel retailer reported adjusted quarterly profit of 60 cents a share, 1 cent a share above estimates. However, the parent of Gap, Banana Republic, and Old Navy gave lower-than-expected full-year guidance and said it was still unsatisfied with the pace of improvement.
Applied Materials — Applied Materials came in 2 cents a share above estimates with adjusted quarterly profit of 50 cents per share. Revenue was essentially in line. The maker of semiconductor manufacturing equipment gave better-than-expected current-quarter guidance, after orders reached a record high last quarter.
Ross Stores — Ross Stores earned 71 cents per share for its latest quarter, 4 cents a share above estimates. The discount retailer saw revenues come in slightly above Street forecasts. Its 4 percent rise in comparable-store sales was also above estimates, and Ross raised its annual earnings guidance.
Viacom — Viacom continues to move closer to a settlement with founder Sumner Redstone, according to multiple reports. Much of the information contained in the latest reports was out previously, but more details are emerging and sources say the announcement is imminent.
Cintas — Cintas shares are under pressure following news that a Louisiana law firm is conducting an investigation into the uniform maker's proposed acquisition of G&K Services for $97.50 per share. The firm is investigating whether the deal undervalues G&K.
