Boohoo said PwC, which has been the group auditor since 2014, is still its auditor at this time and the audit committee has launched a competitive tender process for the company's audit.
Shares in Boohoo are indicated to open 3%-5% lower as per a premarket indicator.
The company last month accepted all the recommendations of an independent review, which found several failings in its supply chain.
The Financial Times newspaper had reported earlier this month that PwC has resigned due to concerns over reputational risk.
