Shortly before 7 a.m. Pacific time on Oct. 6, the chief executive of GT Advanced Technologies Inc. called an Apple Inc. vice president with bad news: GT, which was to supply Apple with superhard sapphire screens for its new iPhones, had filed for bankruptcy 20 minutes earlier.
The filing surprised Apple, because the companies had been negotiating changes in their contract to ease GT’s financial strain, according to a letter Apple later sent to GT’s creditors. Executives of the companies had planned to meet the next day at Apple’s headquarters.
