FTI Consulting Study Reveals Cybersecurity Attacks Are an Increasing Threat to M&A
Third Installment of CISO Redefined Series Highlights Correlation between Cyber Attacks and Transactions, an Emerging Risk for Dealmakers as M&A Volumes Rebound
WASHINGTON, March 17, 2026 (GLOBE NEWSWIRE) -- FTI Consulting, Inc.’s (NYSE: FCN) Cybersecurity and Data Privacy Communications practice today released the third installment of its “CISO Redefined” series, , which looks at the increasing correlation between cybersecurity incidents and corporate transactions.
According to the findings, nearly 1 in 4 executives has experienced a cyber incident during or shortly after a transaction, with nearly half of respondents (42%) experiencing significant deal value reduction. More than half (58%) said financial targets were impaired, while 20% said their deals were either delayed or paused due to a cyber incident.
“Threat actors are smart; they read the news and know companies tend to be vulnerable when they’re trying to close or right after when they’re integrating systems — and that’s when they try to break in,” said , Global Head of the Cybersecurity and Data Privacy Communications practice at FTI Consulting. “The incident ends up costing the acquirer big time, and most often, the target and acquirer haven’t even begun to think about how to integrate their security plans, let alone how they’ll work together to respond to a cyber crisis if it occurs right after a deal closes. That lack of coordination can have serious blowback on reputation.”
According to , which was released in 2024, the vast majority of CISOs feel their role is misunderstood by company leadership, and they struggle to communicate in a non-technical way that other executives can understand. This sentiment explains the results of the latest survey, which show that the CISO’s voice and opinions — and therefore cyber risk — are not being prioritized.
Going further, 67% of heads of M&A and 76% of general counsel said the CISO is very critical during a transaction. However, 34% of CISOs said they are not heavily involved in contributing to decisions when executing transactions, and 1 in 3 CISOs do not believe they have the authority or are unsure of whether they can stop a transaction if cybersecurity risks are too high.
Other key findings:
- One in 4 CISOs say their leaders push to close deals quickly over conducting thorough cybersecurity due diligence.
- Only 17% of CISOs said that collaboration between cybersecurity and corporate development teams significantly increased during the transaction period. By contrast, 34% of general counsel felt collaboration significantly increased — showing a notable disconnect.
- Only 23% of executives say they manage cybersecurity risks proactively post-close. This decline in vigilance creates a meaningful exposure point for the organization, which coincides with when attacks tend to occur.
“Deal teams need to account for cyber risk much the same way we think about leak risk. These unexpected disruptions can create confusion, shift value and slow negotiations,” said , Americas Head of M&A and Activism at FTI Consulting. “It is essential that dealmakers recognize that transactions are increasingly becoming highly visible targets for threat actors. If deal value is going to be successfully realized, this risk needs to be mitigated more effectively.”
