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.
Hidden among the majestic canyons of the Utah desert, about 7 miles from the nearest town, is a small research facility meant to prepare humans for life on Mars.
The Mars Society, a nonprofit organization that runs the Mars Desert Research Station, or MDRS, invited CNBC to shadow one of its analog crews on a recent mission.
“MDRS is the best analog astronaut environment,” said Urban Koi, who served as health and safety officer for Crew 315. “The terrain is extremely similar to the Mars terrain and the protocols, research, science and engineering that occurs here is very similar to what we would do if we were to travel to Mars.”
SpaceX CEO and Mars advocate Elon Musk has said his company can get humans to Mars as early as 2029.
The 5-person Crew 315 spent two weeks living at the research station following the same procedures that they would on Mars.
David Laude, who served as the crew’s commander, described a typical day.
“So we all gather around by 7 a.m. around a common table in the upper deck and we have breakfast,” he said. “Around 8:00 we have our first meeting of the day where we plan out the day. And then in the morning, we usually have an EVA of two or three people and usually another one in the afternoon.”
An EVA refers to extravehicular activity. In NASA speak, EVAs refer to spacewalks, when astronauts leave the pressurized space station and must wear spacesuits to survive in space.
“I think the most challenging thing about these analog missions is just getting into a rhythm. … Although here the risk is lower, on Mars performing those daily tasks are what keeps us alive,” said Michael Andrews, the engineer for Crew 315.

Apple had two major launches last month. They couldn’t have been more different.
First, Apple revealed some of the artificial intelligence advancements it had been working on in the past year when it released developer versions of its operating systems to muted applause at its annual developer’s conference, WWDC. Then, at the end of the month, Apple hit the red carpet as its first true blockbuster movie, “F1,” debuted to over $155 million — and glowing reviews — in its first weekend.
While “F1” was a victory lap for Apple, highlighting the strength of its long-term outlook, the growth of its services business and its ability to tap into culture, Wall Street’s reaction to the company’s AI announcements at WWDC suggest there’s some trouble underneath the hood.
“F1” showed Apple at its best — in particular, its ability to invest in new, long-term projects. When Apple TV+ launched in 2019, it had only a handful of original shows and one movie, a film festival darling called “Hala” that didn’t even share its box office revenue.
Despite Apple TV+being written off as a costly side-project, Apple stuck with its plan over the years, expanding its staff and operation in Culver City, California. That allowed the company to build up Hollywood connections, especially for TV shows, and build an entertainment track record. Now, an Apple Original can lead the box office on a summer weekend, the prime season for blockbuster films.
The success of “F1” also highlights Apple’s significant marketing machine and ability to get big-name talent to appear with its leadership. Apple pulled out all the stops to market the movie, including using its Wallet app to send a push notification with a discount for tickets to the film. To promote “F1,” Cook appeared with movie star Brad Pitt at an Apple store in New York and posted a video with actual F1 racer Lewis Hamilton, who was one of the film’s producers.

Although Apple services chief Eddy Cue said in a recent interview that Apple needs the its film business to be profitable to “continue to do great things,” “F1” isn’t just about the bottom line for the company.
Apple’s Hollywood productions are perhaps the most prominent face of the company’s services business, a profit engine that has been an investor favorite since the iPhone maker started highlighting the division in 2016.
Films will only ever be a small fraction of the services unit, which also includes payments, iCloud subscriptions, magazine bundles, Apple Music, game bundles, warranties, fees related to digital payments and ad sales. Plus, even the biggest box office smashes would be small on Apple’s scale — the company does over $1 billion in sales on average every day.
But movies are the only services component that can get celebrities like Pitt or George Clooney to appear next to an Apple logo — and the success of “F1” means that Apple could do more big popcorn films in the future.
“Nothing breeds success or inspires future investment like a current success,” said Comscore senior media analyst Paul Dergarabedian.
But if “F1” is a sign that Apple’s services business is in full throttle, the company’s AI struggles are a “check engine” light that won’t turn off.
Replacing Siri’s engine
At WWDC last month, Wall Street was eager to hear about the company’s plans for Apple Intelligence, its suite of AI features that it first revealed in 2024. Apple Intelligence, which is a key tenet of the company’s hardware products, had a rollout marred by delays and underwhelming features.
Apple spent most of WWDC going over smaller machine learning features, but did not reveal what investors and consumers increasingly want: A sophisticated Siri that can converse fluidly and get stuff done, like making a restaurant reservation. In the age of OpenAI’s ChatGPT, Anthropic’s Claude and Google’s Gemini, the expectation of AI assistants among consumers is growing beyond “Siri, how’s the weather?”
The company had previewed a significantly improved Siri in the summer of 2024, but earlier this year, those features were delayed to sometime in 2026. At WWDC, Apple didn’t offer any updates about the improved Siri beyond that the company was “continuing its work to deliver” the features in the “coming year.” Some observers reduced their expectations for Apple’s AI after the conference.
“Current expectations for Apple Intelligence to kickstart a super upgrade cycle are too high, in our view,” wrote Jefferies analysts this week.
Siri should be an example of how Apple’s ability to improve products and projects over the long-term makes it tough to compete with.
It beat nearly every other voice assistant to market when it first debuted on iPhones in 2011. Fourteen years later, Siri remains essentially the same one-off, rigid, question-and-answer system that struggles with open-ended questions and dates, even after the invention in recent years of sophisticated voice bots based on generative AI technology that can hold a conversation.
Apple’s strongest rivals, including Android parent Google, have done way more to integrate sophisticated AI assistants into their devices than Apple has. And Google doesn’t have the same reflex against collecting data and cloud processing as privacy-obsessed Apple.
Some analysts have said they believe Apple has a few years before the company’s lack of competitive AI features will start to show up in device sales, given the company’s large installed base and high customer loyalty. But Apple can’t get lapped before it re-enters the race, and its former design guru Jony Ive is now working on new hardware with OpenAI, ramping up the pressure in Cupertino.
“The three-year problem, which is within an investment time frame, is that Android is racing ahead,” Needham senior internet analyst Laura Martin said on CNBC this week.
Apple’s services success with projects like “F1” is an example of what the company can do when it sets clear goals in public and then executes them over extended time-frames.
Its AI strategy could use a similar long-term plan, as customers and investors wonder when Apple will fully embrace the technology that has captivated Silicon Valley.
Wall Street’s anxiety over Apple’s AI struggles was evident this week after Bloomberg reported that Apple was considering replacing Siri’s engine with Anthropic or OpenAI’s technology, as opposed to its own foundation models.
The move, if it were to happen, would contradict one of Apple’s most important strategies in the Cook era: Apple wants to own its core technologies, like the touchscreen, processor, modem and maps software, not buy them from suppliers.
Using external technology would be an admission that Apple Foundation Models aren’t good enough yet for what the company wants to do with Siri.
“They’ve fallen farther and farther behind, and they need to supercharge their generative AI efforts” Martin said. “They can’t do that internally.”
Apple might even pay billions for the use of Anthropic’s AI software, according to the Bloombergreport. If Apple were to pay for AI, it would be a reversal from current services deals, like the search deal with Alphabet where the Cupertino company gets paid $20 billion per year to push iPhone traffic to Google Search.
The company didn’t confirm the report and declined comment, but Wall Street welcomed the report and Apple shares rose.
In the world of AI in Silicon Valley, signing bonuses for the kinds of engineers that can develop new models can range up to $100 million, according to OpenAI CEO Sam Altman.
“I can’t see Apple doing that,” Martin said.
Earlier this week, Meta CEO Mark Zuckerberg sent a memo bragging about hiring 11 AI experts from companies such as OpenAI, Anthropic, and Google’s DeepMind. That came after Zuckerberg hired Scale AI CEO Alexandr Wang to lead a new AI division as part of a $14.3 billion deal.
Meta’s not the only company to spend hundreds of millions on AI celebrities to get them in the building. Google spent big to hire away the founders of Character.AI, Microsoft got its AI leader by striking a deal with Inflection and Amazon hired the executive team of Adept to bulk up its AI roster.
Apple, on the other hand, hasn’t announced any big AI hires in recent years. While Cook rubs shoulders with Pitt, the actual race may be passing Apple by.

Tesla CEO Elon Musk, who bombarded President Donald Trump‘s signature spending bill for weeks, on Friday made his first comments since the legislation passed.
Musk backed a post on X by Sen. Rand Paul, R-Ky., who said the bill’s budget “explodes the deficit” and continues a pattern of “short-term politicking over long-term sustainability.”
The House of Representatives narrowly passed the One Big Beautiful Bill Act on Thursday, sending it to Trump to sign into law.
Paul and Musk have been vocal opponents of Trump’s tax and spending bill, and repeatedly called out the potential for the spending package to increase the national debt.
The independent Congressional Budget Office has said the bill could add $3.4 trillion to the $36.2 trillion of U.S. debt over the next decade. The White House has labeled the agency as “partisan” and continuously refuted the CBO’s estimates.

The bill includes trillions of dollars in tax cuts, increased spending for immigration enforcement and large cuts to funding for Medicaid and other programs.
It also cuts tax credits and support for solar and wind energy and electric vehicles, a particularly sore spot for Musk, who has several companies that benefit from the programs.
“I took away his EV Mandate that forced everyone to buy Electric Cars that nobody else wanted (that he knew for months I was going to do!), and he just went CRAZY!” Trump wrote in a social media post in early June as the pair traded insults and threats.
Shares of Tesla plummeted as the feud intensified, with the company losing $152 billion in market cap on June 5 and putting the company below $1 trillion in value. The stock has largely rebounded since, but is still below where it was trading before the ruckus with Trump.
