Cyber threats erode Energy M&A value during integration

The energy sector is experiencing unprecedented mergers and acquisitions (M&A) activity, with deal value surging 38 percent in the second half of 2025 as larger, portfolio-defining transactions reshape the industry landscape. However, this trend of consolidation is exposing a key weakness: cybersecurity threats that emerge during integration can potentially undermine the value these deals are meant to deliver. As energy companies rush to complete complex transactions faster than traditional diligence processes can support, they are inheriting hidden cyber exposures in legacy operational technology systems never designed for the rapid changes demanded by modern M&A integration.

The hidden threat to your deal success:

• Short timelines and restricted access during due diligence leave acquirers blind to embedded vulnerabilities across legacy infrastructure. When integration begins, these hidden "gotchas" surface as operational disruption, regulatory scrutiny, and eroded deal value.
• Energy sector operational technology platforms were built for isolation, not integration. M&A transactions disrupt these assumptions, creating new access paths and expanding attack surfaces precisely when cybersecurity controls are in flux.
• Vendor connections extend trust beyond enterprise boundaries through remote access and outsourced administration. Contractual assurances can't replace comprehensive technical evaluation of these critical vulnerabilities.
