TL;DR: Identity readiness can be as financially material as balance-sheet diligence in mergers and acquisitions because excess access, dormant accounts and toxic combinations slow cutover, inflate TSA costs and increase audit risk, according to Gathid. The control problem is not just visibility, but whether identity data is clean enough to simulate and safely change access before Day One.

Questions worth separating out
Q: How should IAM teams handle access governance during a merger or acquisition?
A: Treat access governance as part of transaction execution, not a post-close remediation project.
Q: Why do mergers and acquisitions create identity risk even when the acquirer has strong IAM controls?
A: Strong steady-state IAM controls do not remove inherited identity debt from the target company.
Q: What breaks when access relationships are only reviewed through spreadsheet exports?
A: Spreadsheet exports miss context.
Practitioner guidance
- Baseline access before Day One planning Ingest HR, directory and material system data in read-only mode, then reconcile accounts to owners so the deal team can see where access is orphaned or duplicated.
- Map toxic combinations across finance and revenue systems Identify request-and-approve conflicts, payment privileges and supplier-master rights before integration changes are scheduled, because these are the access paths most likely to create material control failures.
- Simulate role changes before pushing them live Test deprovisioning, group reassignments and entity splits in a digital twin first, then apply approved changes through systems of record so the audit trail stays intact.
What's in the full article
Gathid's full article covers the operational detail this post intentionally leaves for the source:
- The specific four metrics CFOs should ask for in the first two weeks of diligence, including reconciliation and exception measures.
- A phased 100-day roadmap showing how to sequence read-only ingest, remediation, simulation and evidence export.
- Examples of how finance, revenue, supply chain and IT/OT teams should map access into the integration plan.
- The article's board-level framing for materiality, velocity, cost to assure and residual risk.

Identity readiness is a financial control, not a back-office hygiene task. The article is right to treat access quality as material to deal value because unresolved privileges directly affect integration speed, TSA spend and audit confidence. M&A turns identity into a board-level control problem where access evidence must be current, not inferred. Practitioners should position identity readiness as part of transaction governance, not post-close cleanup.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
- Only 44% of organisations have implemented any policies to manage their AI agents, despite 92% agreeing that governing AI agents is critical to enterprise security.
A question worth separating out:
Q: Who should own identity readiness in an M&A programme?
A: Identity readiness should be jointly owned by deal leadership, IAM, finance and the business process owners who understand material systems. The control is financial, operational and technical at once, so accountability has to sit with the integration workstream rather than only with the security team.
