While Toshiba appears to have averted the risk of immediate delisting from the Tokyo Stock Exchange by submitting its annual financial results with sign-off by an auditor ahead of the deadline, the Japanese conglomerate's prospects of maintaining its listing remain far from certain.

On Thursday, Toshiba handed its financial results for the business year ended March 2017 to the Kanto Local Finance Bureau after missing the original deadline in June. The report came with a "qualified opinion" from auditor PricewaterhouseCoopers Aarata LLC, which means that while the results contain minor problems, overall they are presented fairly.

PwC Aarata gave an "adverse" statement on the company's internal controls, however, saying it had overlooked massive losses related to the company's now-bankrupt U.S. unit.
