LONDON — Cyber ​​security company Darktrace on Monday said it has appointed accounting firm EY to review its “key financial processes and controls”, in a bid to calm investor fears after a short seller accused the firm of manipulating its accounts.

“The board has full confidence in the robustness of Darktrace’s financial processes and controls. As a sign of that confidence, we have commissioned this independent third-party review of E&Y,” Geoffrey Hurst, chairman of the board, said in a statement. “We look forward to the outcome of this review.”

EY will report to the chair of Darktrace’s audit and risk committee, Paul Harrison, Darktrace said. Darktrace said it did not expect to be in a position to update markets on the review by the time of its first-half earnings report on March 8 and did not provide a timeline or when it would release the results.

Darktrace shares rose more than 2% on Monday following the announcement. The stock is up 4% so far this year despite a sharp fall in late January.

Darktrace, whose tools enable companies to fight cyber threats with artificial intelligence, was targeted last month in a report by New York-based asset manager Quintessential Capital Management, which investigated Darktrace’s business model and sales practices.

QCM said it found alleged flaws in Darktrace’s accounting, including “round-tripping” and “channel stuffing” practices that seek to boost revenue. The company said it was “deeply skeptical of the validity of Darktrace’s financial statements” and believed sales and growth rates may have been overstated.

Darktrace pushed back at the claims, with its CEO Poppy Gustafsson defending the company from what she called “unfounded conclusions” by QCM, saying it had “robust processes in our business.” She added: “I stand by my team and the business I represent.”
