NEW YORK—  Eastman Kodak, the 133-year-old photography company, is warning investors thats it might not survive much longer. In its earnings report the company warned that it doesn’t have “committed financing or available liquidity” to pay its roughly $500 million in upcoming debt obligations. “These conditions raise substantial doubt about the company’s ability to continue as a going concern,”Kodak said in a filing. Kodak aims to conjure up cash by ceasing payments for its retirement pension plan. It also said that it doesn’t expect tariffs to have “material impacts” on its business because it manufactures its many of its products, includings plates , inks and film in the United States. Sales at Kodak’s print division fell and the unit made a loss last year, but the manufacture was confident that printing plate tariffs would help.
