From pre-acquisition technical due diligence through Day 1 readiness to full post-merger integration — we de-risk the technology workstream so the deal delivers what the model promised.
NDA signed before any briefing · Fully confidential · Available pre-LOI
Poor technical integration is the most common reason M&A deals fail to realise their projected synergies. These are the outcomes we consistently deliver.
Results reflect typical engagement outcomes. Deal complexity, target maturity, and scope affect individual timelines.
Every engagement we run achieves operational continuity on Day 1 — employees connected, systems accessible, and communications functional from the moment the deal closes.
Technical due diligence consistently surfaces material risks — legacy debt, licensing exposure, security gaps — before they become post-close liabilities.
Structured integration planning and execution compresses the synergy timeline — cost savings and revenue enablement realised months earlier than unmanaged integration.
Application rationalisation, licence consolidation, and infrastructure deduplication typically delivers 25–35% reduction in combined technology spend post-integration.
Technical integration complexity is consistently underestimated by deal teams. We exist to ensure the technology workstream keeps pace with the legal and financial close — and delivers the synergies the model projected.
From pre-LOI due diligence through to full post-merger integration and carve-out execution — a complete technical programme managed by experienced integration architects.
Pre-deal assessment of the target's technology estate — infrastructure, applications, security posture, technical debt, licensing, and team capability. Findings mapped to deal risk and synergy impact.
Detailed planning for operational continuity from the moment the deal closes — email, identity, network access, communications, and critical applications all functional on Day 1 regardless of integration progress.
A dedicated technical IMO to plan, track, and govern the technology integration programme — workstream ownership, dependency mapping, risk management, and status reporting to deal leadership.
Merging Active Directory and Entra ID tenants, resolving UPN conflicts, migrating mailboxes and calendars, harmonising group policies, and establishing a unified identity platform across the combined entity.
WAN, LAN, and SD-WAN integration across sites. Firewall policy harmonisation, IP addressing conflicts, VPN consolidation, and data centre rationalisation — mapped to a defined consolidation roadmap.
Migration of critical data assets — files, email, structured databases, and SharePoint/intranet — from target to acquirer systems. Data mapping, cleansing, and governance throughout.
Unified security baseline across the combined entity — endpoint protection, SIEM integration, vulnerability management, and compliance posture (ISO 27001, Cyber Essentials, GDPR) for the merged organisation.
Audit and rationalisation of duplicate and redundant applications across the combined estate. Build/buy/retire/consolidate decisions, licence optimisation, and decommissioning roadmap with cost savings quantified.
For divestitures and carve-outs: separation of shared infrastructure, TSA (Transition Service Agreement) management, data segregation, and standing up an independent technology environment for the carved-out entity.
Technical due diligence is not a checkbox exercise. It is a structured investigation into every dimension of the target's technology estate — designed to surface material risks, validate synergy assumptions, and inform price and structure negotiation.
On-premises and cloud infrastructure assessment. Server estate, networking, DR/BCP capability, hosting costs, and scalability headroom. Cloud readiness and migration cost modelling.
Full application inventory — ERP, CRM, bespoke systems, SaaS subscriptions, integrations, and APIs. Identifying duplication with acquirer estate and flagging sunset or unsupported systems.
Vulnerability assessment, patch currency, endpoint protection, access controls, incident history, and exposure to common attack vectors. Quantifying remediation cost and residual risk.
Software licence compliance review — Microsoft, Oracle, SAP, and custom vendors. Open-source licence exposure. GDPR data processing practices and any outstanding regulatory findings.
Assessing the cost and risk of deferred technology investment — legacy systems, unsupported platforms, absent documentation, and unresolved architectural decisions that will require post-close investment.
Evaluating the target's IT function — team structure, capability, key person dependencies, contractor reliance, and cultural fit with the acquirer's technology operating model.
Illustrative examples of the risk categories and severity levels surfaced during technical due diligence engagements.
| Finding | Area | Severity | Deal implication |
|---|---|---|---|
| Microsoft SQL Server licences non-compliant — 40% under-licensed | Licensing | High | Estimated £180k remediation liability — price adjustment warranted |
| No functioning disaster recovery — RTO undefined, last test 3 years ago | Infrastructure | High | Material operational risk; DR build required within 90 days post-close |
| Bespoke ERP integration — undocumented, single-developer dependency | Applications | Medium | Key person retention risk; documentation and knowledge transfer required |
| GDPR data processing register absent; cross-border transfers undocumented | Compliance | Medium | Regulatory exposure; warranty language recommended; 60-day remediation plan |
| End-of-life Windows Server 2012 on 8 production systems | Infrastructure | Medium | Security exposure; upgrade programme estimated at £45k; 6 months post-close |
| No MDM solution — 60% of endpoints unmanaged BYOD | Security | Medium | Intune deployment required; cost and timeline factored into integration plan |
| SaaS spend fragmented — 140 subscriptions with no central governance | Licensing / Cost | Low | Rationalisation opportunity; estimated £60k annual saving post-integration |
Technology integration is not a single event — it is a programme of interdependent workstreams that must be sequenced, resourced, and governed. Our playbook has been refined across 60+ completed integrations.
Our Integration Management Office tracks progress, dependencies, and risks across every technical workstream — giving deal leadership a single, accurate view of integration status at all times.
Carve-outs demand everything that integrations do — but in reverse, under TSA clock pressure, and with the added complexity of establishing a fully independent technology environment for an entity that has never stood alone.
Identifying every technology service the carve-out entity currently receives from the parent — ERP, email, network, helpdesk, security tooling — and defining the separation scope for each.
Structuring Transition Service Agreements that are specific, time-bound, and technically deliverable. Managing service consumption and exit against TSA milestones to minimise exit costs.
Building the carve-out entity's independent technology environment — cloud tenancy, network, security, and end-user computing — on a timeline aligned to TSA exit obligations.
Identifying, extracting, and transferring the data assets belonging to the carved-out entity — with clean separation from parent data, full chain of custody, and GDPR-compliant transfer mechanics.
Managing the TUPE transfer or redeployment of IT staff, knowledge transfer from parent IT function, and establishing the carve-out entity's independent IT operating model and governance.
Outcomes from M&A technical integration, due diligence, and carve-out engagements across private equity, corporate, and public sector deals.
Technical risk identified during pre-deal due diligence for a PE acquirer — comprising £1.1M of undisclosed licensing liability, £800k of infrastructure remediation, and £500k of GDPR exposure — resulting in a successful price renegotiation.
Technical Due DiligenceFull operational continuity achieved on close day for a 600-user cross-border acquisition — email, identity, network access, and communications live across 3 countries before the ink was dry, with zero service interruption reported.
Day 1 ReadinessAnnual technology cost reduction realised 4 months post-close following application rationalisation (38 systems decommissioned), M365 licence consolidation, and infrastructure deduplication across two merged entities.
Post-Merger IntegrationComplete technology carve-out for a 350-user entity divested from a FTSE 250 business — independent M365 tenant, network, security, and ERP environment stood up within 90 days, exiting all parent TSAs ahead of the contractual deadline.
Carve-Out ExecutionEvery M&A engagement is different. We offer fixed-scope due diligence engagements, full integration programme delivery, and advisory retainers for deal teams that need embedded technical expertise throughout the transaction lifecycle.
