Check out which companies are making headlines before the bell on Tuesday:
DuPont - The chemical giant earned $0.11 per share, excluding certain items, for the fourth quarter, four cents above estimates, despite flat sales and higher costs. Its 2013 outlook, however, was above current estimates.
Verizon Communications - Verizon earned $0.38 per share for the fourth quarter, excluding certain items, 12 cents short of estimates. Its results were impacted by super storm Sandy and the introduction of Apple's iPhone 5.
Travelers - The insurance company scored a big beat by reporting fourth-quarter profit of $0.72 per share, excluding certain items, compared to estimates of 14 cents. Despite the impact of Sandy, it also saw a significant improvement in underwriting margins.
