What types of M&A situations do you cover?

Card portfolio acquisitions and transfers, full bank or EMI acquisitions requiring core banking consolidation, issuer platform migrations following processor or servicer changes triggered by M&A, and post-merger rationalisation of duplicate payment infrastructure. The common thread is that a regulated technology estate needs to move, and the timeline and compliance constraints are non-negotiable.

How early in the process should we engage?

Before the integration workplan is signed off — ideally before the technical schedule in the sale and purchase agreement is agreed. The technical sequencing assumptions baked into deal timelines are frequently optimistic in ways that are only visible to someone who has run the migration. Engaging post-signing is workable; engaging post-SPA is harder.

Can you work alongside our existing system integrator or vendor?

Yes. We typically operate as the client-side technical authority — the counterpart who can interrogate the vendor's delivery plan, identify sequencing risks, and escalate with specificity. We are not a system integrator and are not competing with one. We hold the client's interest in a programme where multiple vendors have their own.

Service

M&A Technology Integration

Technology integration leadership for financial institutions following mergers, acquisitions, and portfolio transfers — from target architecture and day-one readiness through platform consolidation, scheme re-certification, and regulatory continuity. Senior architects with production experience on the systems that need to be joined together.

Get in touch

Financial services M&A is technically harder than it looks from a deal sheet. Acquired entities run on different core banking platforms, different card switches, and different scheme certifications. Data models diverge in ways that matter — for reconciliation, for regulatory reporting, for risk — and the integration timeline is set by a signed agreement, not by engineering readiness. The failure modes are well-documented: parallel-run overruns, scheme certification delays, regulatory breaches during the migration window, and customer incidents at cutover that become regulatory findings. What is less well-documented is how to avoid them.

We have led card portfolio migrations, core banking consolidations, and payment platform cutovers at tier-one scale — including a programme spanning issuing platform re-platforming, scheme re-certification, and regulated cutover across a live production estate. That background is not decorative. It shapes how we scope, sequence, and de-risk every engagement.

What You Get

Integration diagnostic and risk register

A structured assessment of both estates — platforms, integration layers, data models, scheme positions, regulatory permissions, and operational dependencies. The output is not a gap list; it is a sequenced risk register with ownership, mitigation paths, and the minimum viable decisions that must be made before engineering can begin. Completed in weeks, not quarters, because the timeline rarely allows otherwise.

Target architecture and consolidation design

Definition of the consolidated state — which platform survives, which is decommissioned, which components are retained from each side, and how the migration is sequenced to preserve regulatory continuity and scheme compliance throughout. Architecture designed by engineers who have run the platforms in question, not by analysts who have read the vendor documentation.

Card portfolio migration

End-to-end technical leadership for card portfolio transfers — issuing and acquiring — including platform configuration, BIN and card product mapping, authorisation routing, settlement file reconciliation, and the cutover choreography that determines whether the migration is invisible to cardholders or becomes a major incident. Scheme certification managed in parallel, not sequentially.

Core banking and payment platform consolidation

Technical design and delivery oversight for consolidating two entities onto a single core banking or payment processing platform. Data migration strategy, dual-run sequencing, reconciliation framework, and the regulatory reporting continuity that acquisition agreements rarely address with sufficient precision.

Scheme re-certification and compliance continuity

Visa, Mastercard, and domestic scheme certifications do not transfer with an acquisition. We support the re-certification workload — scheme registration, testing environment access, test case execution, and scheme sign-off — as a parallel workstream to platform migration, not an afterthought. PCI DSS scope redefinition and DORA operational resilience obligations during the integration period are addressed as part of the same programme, not separately.

Programme governance and cutover management

Integration Management Office design, dependency mapping across workstreams, milestone governance, and the cutover command structure that manages a live banking migration on the night. Stakeholder communication to board, regulator, and scheme levels where the engagement warrants it.

Our Approach

Integration diagnostic

Structured assessment of both technology estates within the first weeks of engagement. Platforms, data models, scheme positions, regulatory permissions, and operational dependencies mapped. Risk register and sequencing plan delivered before engineering commitments are made.

Target architecture

Consolidated state defined — platform selection, migration sequencing, data consolidation approach, and the regulatory continuity model that governs the programme. Architecture options developed with commercial and technical trade-offs made explicit.

Parallel workstream design

Programme structured with platform migration, scheme re-certification, regulatory notification, and data migration running in parallel under a unified dependency model — not sequentially, which is where programmes typically lose six to twelve months.

Delivery leadership

Senior architects embedded in delivery — in workstream governance, in vendor management, in scheme and regulator conversations. Weekly dependency resolution rather than monthly programme reporting.

Cutover and stabilisation

Live cutover managed with a defined command structure, real-time reconciliation monitoring, and pre-agreed rollback criteria. Post-cutover hypercare until the consolidated estate is stable and decommissioning of the legacy platform can proceed safely.
