Market Insider | What's Shaking | Earnings to Watch | Before the Bell

Check out which companies are making headlines before the bell on Thursday:

Campbell Soup - Depending on various inclusions and exclusions, the soup maker reported adjusted fourth quarter earnings figures of 45 cents, 43 cents, and 37 cents per share. Street analysts had estimated Campbell would earn 42 cents per share during the quarter. The company said its results were helped by better performance for its U.S. soup business, as well as its Pepperidge Farm unit.

Pall Corp.- The maker of filtration systems earned 90 cents per share, excluding certain items, for its fiscal fourth quarter, beating estimates by a cent. Sales were also better than expected, although Pall's industrial markets have seen soft demand in recent quarters.

Verizon, Vodafone - The two companies are in talks about a possible purchase by Verizon of Vodafone's 45 percent stake in their Verizon Wireless joint venture.

Guess - Guess reported second quarter profit of 52 cents per share, 16 cents above estimates. Revenue also topped consensus, but the retailer is also projecting current quarter profit below current analyst forecasts. Investors are focusing on the upbeat second quarter, which came amid better than expected sales in North America.

U.S. Airways, American Airlines parent AMR - The two airlines and the Justice Department all say they are open to negotiating a possible settlement of the DOJ suit to prevent the proposed mergerof U.S. Airways and American. But there is no indication that any sort of agreement is near.
