Accenture's stock fell by 20% while the company acquired $4.18 billion worth of cybersecurity.

      Accenture experienced its most challenging day on the stock market on Thursday, largely due to concerns that AI could significantly impact the consulting sector. Shares plummeted by as much as 20 percent, marking the steepest one-day decline in the company's history, after it projected lower revenue for the current quarter. The stock has now decreased by over 50 percent this year.

      The immediate factors behind this drop included a disappointing outlook and the ongoing conflict in the Middle East, which Accenture attributed to a loss of approximately $400 million in sales for the quarter, with further losses anticipated. However, the more profound concern is of a structural nature.

      Bloomberg Intelligence indicated that "AI is disrupting demand across consulting and managed services." Scott Kleinman of Apollo recently stated that professional services, including law firms, accounting firms, and consultancies, are the next industry likely to be affected by AI, following the software sector.

      For a company that specializes in AI transformation, the concern is that this same technology might render much of its workforce obsolete.

      Other competitors also faced declines, with Capgemini and Infosys seeing drops of over 30 percent this year, while Cognizant and IBM also fell on the same day.

      Examining the drop's context: the quarterly performance wasn’t disastrous; revenue increased by 6 percent to $18.7 billion, and earnings per share rose by 9 percent to $3.80. The issue that unsettled investors was the forward guidance. New bookings declined by about 2 percent, Accenture projected current-quarter revenue below analysts’ expectations, and it adjusted its full-year growth forecast down to 3 to 4 percent.

      On the same day, Accenture explicitly clarified its strategic shift by agreeing to acquire a majority stake in Dragos and the entirety of runZero and NetRise for a total of $4.18 billion, aiming to strengthen its position in operational technology security.

      The three companies focus on securing operational technologies that are critical for power grids, pipelines, factories, and data centers. Accenture argues that this sector is severely underfunded, especially as AI increases the interconnectivity and vulnerability of critical infrastructure.

      These acquisitions are expected to add around $208 million in annual recurring revenue and enhance a cybersecurity division that expanded from $700 million in 2016 to $10 billion in the previous year. This is part of a broader strategy: Accenture has announced plans to invest $9 billion on acquisitions this year, an increase from $5 billion, and it has also made smaller purchases, including the Siemens-focused software firm IndX and the Italian digital health company Alfahealth.

      The rationale mirrors the drivers of the stock selloff, in a reversed manner. As AI risks automating many white-collar tasks central to Accenture’s business, the company is proactively investing in areas of technology that are expanding and less susceptible to replacement, such as safeguarding critical infrastructure against increasingly AI-driven attacks.

      The lingering question for the consulting industry is whether a $4.18 billion investment in cybersecurity will be sufficient to mitigate the disruptions affecting stock values.
