Toshiba Corp. on Friday finalized the sale of its chip business, releasing the embattled company from its worst-ever crisis but selling off its crown jewels. Now the scandal-hit electronics firm must ask itself a big question: What has it got left to drive growth?

Analysts say the energy and infrastructure divisions could eventually replace the chip business as core operations leading to a stable growth path, but when and to what degree this can happen remains unclear.

"With the sale of Toshiba Memory (Corp.), Toshiba has escaped a financial crisis and will move toward fiscal stabilization for now," said Mitsuo Shimizu, equity strategist at Japan Asia Securities Co.
