Accenture Plummets 20% in Stock Market, Its Worst Day Ever: AI Scares the Consulting Market

On June 18, 2026, Accenture recorded the worst stock decline in its history: shares fell by 20% in a single session, already down over 50% since the beginning of the year. The quarterly numbers triggered the sell-off: revenues grew by 6% to $18.7 billion, slightly below expectations of around $18.78 billion; new contracts decreased by 2% year-on-year and 13% compared to the previous quarter; annual guidance cut from 3-5% to 3-4% in local currency. The war in the Middle East has taken away about $400 million in sales for the quarter. Morgan Stanley lowered the rating to Equal Weight from Overweight, citing flat IT budgets in 2026 despite the growing priority of AI.

Investors' deepest fear concerns the long-term outlook: AI could automate a significant portion of the clerical work that is the core of the consulting business, reducing demand for the large system integrations that Accenture is known for. Capgemini and Infosys have also lost over 30% since the beginning of the year, and Cognizant and IBM (which already had a rough day a few months ago) lost ground on the same day.

$4 Billion in Industrial Cybersecurity
On the same day as the crash, Accenture announced acquisitions worth $4.18 billion, focused on critical infrastructure security: a controlling stake in Dragos and the complete acquisition of runZero and NetRise. The three companies are expected to collectively generate about $208 million in annual recurring revenues by June 2026, with an annual growth rate of 53%.

Dragos is a platform specialized in threat detection for operational technology (OT) environments: industrial control systems that govern power plants, pipelines, factories, and data centers. runZero focuses on network resource discovery and attack surface assessment. NetRise provides firmware-level analysis and visibility into the software supply chain. The logic is to shift towards segments considered more resistant to automation. Accenture's cybersecurity division has already grown from $700 million in 2016 to $10 billion in fiscal 2025, with a compound annual growth rate of 35%. The transactions are expected to close between August and September 2026, subject to regulatory approvals.

The acquisition plan for the current fiscal year is worth a total of $9 billion, compared to $5 billion the previous year. In the same week, Accenture also announced the acquisition of IndX, specializing in software for Siemens environments, and Alfahealth, an Italian digital health company.
