Check out which companies are making headlines before the bell:

Abercrombie & Fitch–The teen apparel retailer earned $1.34 per share for the fourth quarter, excluding certain items, beating estimates of $1.03, but sales fell below estimates. Comparable store sales fell 8 percent during the quarter, slightly better than estimates.

Delta Air Lines–Delta is revamping its SkyMiles program, effective in January 2015, awarding points based on dollars spent rather than miles flown.

LinkedIn–RBC Capital upgraded the stock to "outperform" to "sector perform", with analyst Mark Mahaney saying the stock's underperformance has created a buying opportunity. The stock had jumped yesterday following news that it introduced a Chinese language website.

Humana–Citi downgraded the health insurer's stock to "sell" from "neutral", based on a recent run-up in the stock's price and concerns about an emphasis on membership over profit margins.

First Solar–The solar equipment maker missed estimates by 10 cents with fourth quarter profit of 89 cents per share, excluding certain items.
