Cybersecurity company Darktrace, one of the U.K.’s most prominent tech names, has found itself under attack from short sellers.
The company, whose tools allow firms to combat cyberthreats with artificial intelligence, was last week targeted in a report by New York-based asset manager Quintessential Capital Management.
QCM, whose stated aim is “exposing fraud and criminal conduct in public companies around the world,” claims it has had a 100% success rate in its activist campaigns.
The company told Reuters it holds a short position of 1.3% in Darktrace shares.
London-based hedge fund Marshall Wace also shorted Darktrace, according to data site Breakout Point.
Short selling is a strategy in which investors bet on the price of a stock going down in value. A trader borrows the stock and then sells it on the assumption that it will fall, before buying it back at a discounted price and pocketing the spread.
What is Darktrace?
Darktrace, one of the U.K.’s largest cybersecurity companies, was founded in 2013 by a group of former intelligence experts and mathematicians.
The Cambridge-headquartered company says its technology uses AI to detect and respond to cyberthreats in a business’ IT systems.
The company floated on the London Stock Exchange in 2021, and its debut was seen as a key victory in the U.K.’s bid to lure more high-growth tech startups to the London market after its withdrawal from the European Union.
The stock’s performance following the listing has been underwhelming. After initially rising to an all-time high of £9.45 ($11.58) in October 2021, Darktrace shares have since plunged dramatically in tandem with a broader slump in global tech stocks.
As of Monday afternoon, Darktrace shares were trading at a price of £2.32, down 37% in the last 12 months.

In August, the firm opened takeover talks with U.S. private equity firm Thoma Bravo. However, Thoma Bravo walked away from the deal a month later after the two sides failed to reach an agreement.
Why is it under attack?
On Tuesday, U.S. hedge fund QCM said it had taken a short position out against Darktrace and published a lengthy report detailing alleged flaws in Darktrace’s accounting.
QCM said that, following an investigation into Darktrace’s business model and selling practices, it was “deeply skeptical about the validity of Darktrace’s financial statements” and believed sales and growth rates may have been overstated.
“We would like to give our strongest possible warning to investors and believe that DT’s equity is overvalued and liable to a major correction, or worse,” QCM said in the report.
Darktrace was accused by QCM of engaging in “channel stuffing” and “round-tripping” — activities that artificially inflate a company’s reported sales — involving individuals with ties to organized crime, money laundering and fraud.
Darktrace didn’t directly address those allegations. On Wednesday, the firm’s CEO Poppy Gustafsson issued a statement defending the company from what she called “unfounded inferences” made by QCM.
Separately, QCM suggested Darktrace may have inflated its revenues by booking unearned revenues as actual sales.
The company occasionally books revenue from payments for contracts it receives before delivering its service to clients as deferred revenue, according to the report.
This is not uncommon among subscription-based software companies. However, QCM noted deferred revenue as a percentage of Darktrace’s sales had dropped between 2018 and 2022, suggesting the firm “may have increasingly been booking unearned revenue as actual sales.”
In response, Darktrace said: “Rarely, customers will pay full contract values in advance but because this is infrequent, non-current deferred revenue balances will decline as these contracts run down unless there is another unusual, large, in-advance payment.”
QCM alleged Darktrace may have tried to fill gaps in its receivables left by clients dropping out of sales negotiations through marketing sponsorships with indebted resellers and using shell companies to pose as phantom clients.
“Organisations that transact with the channel will typically co-host marketing events with their partners. Partner marketing events are a normal course of business for almost all software businesses and Darktrace is no different,” Darktrace said Wednesday.
“This has been, and remains, a very small part of Darktrace’s marketing and the costs of them over the last five years has consistently been substantially below 0.5% of Darktrace’s revenue,” Darktrace added.
Darktrace was not immediately available for comment when contacted by CNBC.
Separately Wednesday, Darktrace said it would embark on a share buyback worth up to £75 million ($92 million) to be completed no later than Oct. 31, 2023.
The Lynch connection
It’s worth noting that, even before the QCM report, there were clouds hanging over Darktrace’s business. Analysts have criticized the company over an allegedly aggressive sales culture and doubts over the value of its technology.
Darktrace is also backed by Mike Lynch, the British tech tycoon.

Lynch founded the enterprise software firm Autonomy, whose sale to Hewlett-Packard was mired in scandal over accusations that Lynch plotted to inflate the value of Autonomy before it was bought by HP for almost $11 billion in 2011.
In 2022, a British judge ruled in favor of HP in a civil fraud case against Lynch. Lynch, an influential figure in the U.K.’s tech scene, faces a possible criminal trial in the U.S. after the U.K. government approved his extradition last year.
He has repeatedly denied the allegations.
Several executives at Darktrace, including Gustafsson and Chief Strategy Officer Nicole Eagan, previously worked for Autonomy.
The QCM report also raised concerns over the connections between Darktrace and Autonomy.
“Darktrace has been led or strongly influenced by many of the very same individuals that participated in the Autonomy debacle,” QCM said in its report.
“If our allegations are confirmed, we expect Darktrace to follow the same tragic destiny of its predecessor, Autonomy,” QCM said.
Meanwhile, Darktrace is also suffering from uncertainty related to the wider macroeconomic environment. The company lowered its forecast for annual recurring revenue growth for the year ending June 2023 to between 29% and 31.5%, down from an earlier forecast of 31% to 34%, citing weaker customer growth.

“TSMC is not engaged in any discussion with other companies regarding any joint venture, technology licensing or technology,” CEO C.C. Wei said on the company’s first-quarter earnings call on Wednesday, dispelling rumors about a collaboration with Intel.
Intel and TSMC were said to have been looking to form a JV as recently as this month. On April 3, The Information reported that the two firms discussed a preliminary agreement to form a tie-up to operate Intel’s chip factories with TSMC owning a 21% stake.
Intel was not immediately available for comment when contacted by CNBC on Wei’s comments on Thursday. The company previously said it doesn’t comment on rumors, when asked by CNBC about the reported discussions.
TSMC’s denial of tie-up talks with Intel comes as President Donald Trump is pushing to address global trade imbalances and reshore manufacturing in the U.S. through tariffs. The Department of Commerce recently kicked off an investigation into semiconductor imports — a move that could result in new tariffs for the chip industry.
TSMC reported a profit beatfor the first quarter thanks to a continued surge in demand for AI chips. However, the company contends with potential headwinds from Trump’s tariffs — which target Taiwan — and stricter export controls on TSMC clients Nvidia and AMD.

Here are TSMC’s first-quarter results versus LSEG consensus estimates:
Revenue: $839.25 billion New Taiwan dollars, vs. NT$835.13 billion expected
Net income: NT$361.56 billion, vs. NT$354.14 billion
TSMC’s reported net income increased 60.3% from a year ago to NT$361.56 billion, while net revenue in the March quarter rose 41.6% from a year earlier to NT$839.25 billion.
The world’s largest contract chip manufacturer has benefited from the AI boom as it produces advanced processors for clients such American chip designer Nvidia.
However, the company faces headwinds from the trade policy of U.S. President Donald Trump, who has placed broad trade tariffs on Taiwan and stricter export controls on TSMC clients Nvidia and AMD.
Semiconductor export controls could also be expanded next month under the “AI diffusion rules” first proposed by the Biden administration, further restricting the sales of chipmakers that use TSMC foundries.
Taiwan currently faces a blanket 10% tariff from the Trump administration and that could rise to 32% after the President’s 90-day pause of his “reciprocal tariffs” ends unless it reaches a deal with the U.S.
As part of efforts to diversify its supply chains, TSMC has been investing billions in overseas facilities, though the lion’s share of its manufacturing remains in Taiwan.
In an apparent response to Trump’s trade policy, TSMC last month announced plans to invest an additional $100 billion in the U.S. on top of the $65 billion it has committed to three plants in the U.S.
On Monday, AMD said it would soon manufacture processor chips at one of the new Arizona-based TSMC facilities, marking the first time that its chips will be manufactured in the U.S.
The same day, Nvidia announced that it has already started production of its Blackwell chips at TSMC’s Arizona plants. It plans to produce up to half a trillion dollars of AI infrastructure in the U.S. over the next four years through partners, including TSMC.
Taiwan-listed shares of TSMC were down about 0.4%. Shares have lost about 20% so far this year.

A day after Nvidia revealed it would incur $5.5 billion in costs related to canceled orders for the H20 chip, which the government said this week requires a license to export to China, the company said it abides by rules on where it can sell its artificial intelligence processors.
“The U.S. government instructs American businesses on what they can sell and where — we follow the government’s directions to the letter,” an Nvidia representative said in a statement.
Nvidia said the statement was in response to a House Select Committee focused on national security threats from China, which opened an investigation into Nvidia’s sales on Wednesday. The H20 was introduced by Nvidia after the Biden administration restricted AI chip exports in 2022. It’s a slowed-down version intended to comply with U.S. export controls.
Nvidia’s brief comment is an indication of how the company is going to defend its business in Washington, D.C., as its technology draws increased scrutiny related to national defense and security. The company’s stock price tumbled almost 7% on Wednesday.
Nvidia’s chips have the vast majority of the market for AI applications, and some were used by China’s DeepSeek to build R1, which upended markets in January.
On Wednesday, the chipmaker touted the taxes it paid, its U.S.-based workforce, and its role as a technology leader.
The company’s exports even help the U.S. fix its trade deficit, the statement said, directly addressing President Trump’s stated reason for introducing tariffs earlier this month.
“NVIDIA protects and enhances national security by creating U.S. jobs and infrastructure, promoting U.S. technology leadership, bringing billions of dollars of tax revenue to the U.S. treasury, and alleviating the massive U.S. trade deficit,” according to the statement.
One challenge for Nvidia is that the H20 was legal for export to China until last week, under previous Biden administration rules. But the House Select Committee said on Wednesday the sale of H20 chips for the past year was effectively a “loophole.”
“The technology industry supports America when it exports to well-known companies worldwide – if the government felt otherwise, it would instruct us,” Nvidia said in its statement.
The government is also investigating whether shipments of restricted chips to China went through Singapore, Nvidia’s second-largest market by billing address with just under $24 billion in sales in the company’s past fiscal year, according to filings.
Nvidia clarified on Wednesday that its Singapore revenue indicates sales with a billing address in the country, often for subsidiaries of U.S. customers.
“The associated products are shipped to other locations, including the United States and Taiwan, not to China,” Nvidia said.
In addition to Chinese export controls and the congressional investigation, Nvidia also faces additional restrictions on what it can export starting next month, under “AI diffusion rules” first proposed by the Biden administration.
