Check out which companies are making headlines before the bell on Tuesday:
DuPont – The company reported third-quarter profit of 45 cents per share, excluding certain items, four cents above estimates. Revenue was essentially in line. Dupont's results were helped by strong performances for solar panel sales, among other products.
Delta Air Lines – Delta beat estimates by five cents, reporting third quarter profit of $1.41 per share, excluding certain items.
Travelers – The insurer earned $2.35 per share for the third quarter, beating estimates by 28 cents, as underwriting margins improved. Travelers also announced a $5 billion addition to its stock buyback program.
United Technologies – United Technologies beat estimates by one cent with third quarter profit of $1.55 per share. Revenue was short, however, due to weakness in military aerospace markets and the slow pace of recovery in Europe. The company did, however, raise the lower end of its earnings forecast for the full year.
Apple – Apple will hold a media event in San Francisco today at which it's expected to introduce new versions of its iPad and iPad mini.
Whirlpool – The appliance maker earned $2.72 per share, excluding certain items, for the third quarter, beating estimates by 11 cents, and also raised its full year forecast because of strong sales.
Lexmark–Lexmark earned 95 cents per share for the third quarter, excluding certain items, beating estimates by four cents. Revenue was well above estimates as well for the provider of printing-related services.
Coach – Coach earned 77 cents per share for the fiscal first quarter, beating estimates by a penny. Revenue was below estimates, as sales remained weak in North America.
RadioShack – The electronics retailer lost $1.11 per share the third quarter, wider than the 35 cent loss analysts were expecting. Revenue was also far short of analyst forecasts, as the company said it continues to address "significant legacy issues". However, it says it's received commitments for new financing as it remakes its stores.
Lockheed Martin – The defense contractor reported third quarter profit of $2.57 per share, excluding certain items, beating estimates of $2.26. Revenue also beat estimates, and Lockheed raised its full year forecast as well.
Netflix – The video service reported third quarter profit of 52 cents per share, three cents above estimates. Netflix also predicted current quarter profit would come in above current Street consensus, and also said it expected to add more than two million domestic subscribers during this quarter.
J.C. Penney – J.C. Penney has announced a revised partnership agreement with Martha Stewart Living, in an effort to resolve an ongoing legal dispute with Macy's, which is suing Martha Stewart for allegedly violating an exclusive merchandising agreement.
VMWare – VMWare earned 84 cents per share for the third quarter, excluding certain items, two cents above estimates. The maker of cloud software also said it is seeing strong licensing revenue growth, and that it expects this trend to continue into 2014.
Discover Financial– Discover reported third quarter profit of $1.20 per share, one cent short of estimates. The credit card issuer's results were impacted by an increase in money reserved to cover defaults.
Rent-A-Center – The company fell 11 cents short of estimates by reporting third quarter profit of 51 cents per share, and its revenue was below Street consensus as well. The equipment rental company cut its full year revenue growth forecast, and predicted full year earnings below analyst estimates.
Texas Instruments – The chipmaker beat estimates by three cents with third quarter profit of 56 cents per share, but its current quarter forecast falls short of consensus. The shortfall comes amid flagging demand for chips used in cars, appliances, and industrial products.
TJX - The discount retailer raised its third quarter outlook above Street estimates, with the company also predicting a quarterly comp store sales increase of four percent. TJX had previously seen same-store sales growth at 2-3 percent.
CIT Group – CIT has reinstated its dividend, with the financing company declaring a quarterly payout of 10 cents per share.
QEP Resources – The oil producer now has hedge fund Jana Partners as its largest shareholder, with an SEC filing indicating Jana has taken a 7.5 percent stake in the company.
Activision Blizzard - CEO Bobby Kotick and co-chairman Brian Kelly now hold a more than 25 percent stake in the videogame maker. That follows completion of the $8.2 billion deal to buy back most of the shares held by France's Vivendi.
