Navigating Compliance Risk in Financial Services Acquisitions

Mergers and acquisitions (“M&A”) are a powerful lever for financial services firms — offering a route to scale, innovation and market expansion. But amid the promise of growth, there’s a persistent and often underestimated risk ─ compliance. Whether acquiring a traditional bank or a FinTech disruptor, firms must address regulation and conduct risks head-on if they want to protect value, gain approval and integrate successfully.

Why Financial Services Firms Pursue M&A and Where Compliance Risk Creeps In

Strategic drivers of M&A in financial services are varied. Market consolidation remains a major theme, especially as the fixed costs of compliance, digital transformation, and risk management outpace the ability of smaller firms to absorb them. Larger institutions are pursuing deals to gain scale and cut duplication. For regional or community banks, consolidation is often a question of survival.

At the same time, technology is reshaping the sector. Established players are acquiring FinTechs to fast-track digital capabilities and reach younger or underserved segments. These deals are less about balance sheet strength and more about accessing talent, platforms and customer experience innovation.

Private equity and venture investors are also driving activity, particularly in payments and digital lending. For many targets, valuations have stabilised, making acquisition a cheaper path to capability than building in-house.

But beneath these strategic objectives lies a complex web of compliance considerations — ranging from regulatory permissions to financial crime risk and cultural fit. If ignored, these can derail a deal or undermine its value post-acquisition.

Understanding the Compliance Risks That Can Derail a Deal

Every acquisition involves absorbing the target’s risk profile and that includes its compliance history. Often, the most material issues are not headline-grabbing breaches, but subtler signs of misalignment ─ outdated systems, underdeveloped governance or a culture that deprioritises compliance.

One of the most immediate risks is regulatory non-compliance. A target may have unresolved findings, ongoing supervisory scrutiny or legacy issues such as mis-selling or poor data handling. These can lead to unexpected remediation costs or affect customer retention.

Consumer protection is another key area. Products that don’t meet current standards on fairness, transparency or accessibility can expose the acquiring firm to conduct risk — particularly if customer journeys are disrupted post-merger.

Financial crime compliance must also be scrutinised. Weak anti-money laundering (“AML”) or sanctions controls, an unusual customer base or opaque ownership structures can all introduce significant legal and reputational risk. This is especially true when acquiring FinTechs, where controls may be less mature.

Cybersecurity and data privacy are increasingly high-risk areas. Merging systems without full visibility of security standards or data handling processes can leave vulnerabilities open to exploitation or breach regulatory requirements.

Cultural incompatibility, while less tangible, often proves decisive. Different attitudes to compliance, governance and accountability can make integration harder, slow down decision-making and weaken control environments.

With growing regulatory focus on operational resilience and consumer outcomes, any delay in addressing these risks can draw the attention of supervisors, damage trust or even block a deal outright.

Mitigating Risk Through Intelligent Due Diligence and Integration Planning

Mitigating compliance risk in M&A begins long before a deal is signed. It requires a clear-eyed view of the acquiring firm’s own risk appetite, strong due diligence, and careful integration planning. But how do you do this in practice? What steps can be taken?

Start with Internal Readiness. Before assessing a target, firms should ensure their own compliance function is equipped to manage integration. This includes having a defined risk appetite, clear escalation channels and sufficient bandwidth to oversee change.

Design Focused Due Diligence. Compliance reviews must go beyond just checklists or tick box exercises. Acquirers should tailor their approach based on the target’s profile and known risks. Key areas of focus include:

Financial Crime: Evaluate AML and sanctions policies, customer screening processes and transaction monitoring effectiveness. Where appropriate, sample high-risk customer files.
Consumer Protection: Review product governance, complaints trends and controls around fair treatment and vulnerable customers.
Data and Technology: Assess the cybersecurity position, privacy compliance and any third-party vendor risks.
Governance and Culture: Examine board reporting, compliance testing results, internal audit coverage and staff experience.
Litigation and Enforcement: Check for outstanding investigations, regulatory warnings, or pending legal action.

Engaging independent advisers for targeted reviews, particularly on financial crime or technology, can add credibility and depth.

Structure Deals with Compliance in Mind. If risks are identified, they should influence deal pricing, warranties and conditions. In some cases, remediation may be required as a condition precedent. Early, transparent engagement with regulators can streamline approvals and reduce post-deal scrutiny.

Plan for Integration Early. Once a deal closes, the acquiring firm becomes responsible for the target’s compliance status. Integration plans should be developed in parallel with due diligence and include:

Post-acquisition compliance risk assessment.
Harmonisation of policies and controls.
Alignment of reporting, training, and governance.
Cultural integration and talent retention, particularly of key risk and compliance staff.
System and data integration, with attention to cybersecurity and regulatory reporting.

In FinTech deals, firms may choose to preserve the target’s autonomy to retain innovation capability. But over time, regulatory standards must converge — requiring a roadmap to align policies, training, and oversight.

Integration isn’t just about risk avoidance; it’s an opportunity to enhance compliance maturity, simplify frameworks and build a stronger risk culture across the combined business.

Buy the Business, Inherit the Risk

Too often, compliance is treated as a blocker to growth rather than a strategic enabler. But in a sector defined by regulation, customer trust and digital transformation, firms that embed compliance into their M&A playbook are more likely to succeed.

They execute deals faster, gain regulator confidence and avoid costly surprises. They retain key staff, integrate systems more smoothly and preserve customer experience. Ultimately, they protect and grow the value they’ve acquired.

M&A can be transformative — but only if compliance risk is seen not as a burden, but as a core dimension of deal success.
