Coconut Software Releases M&A Playbook to Help Banks Navigate Mergers Without Losing Clients, Staff, or Deal Value

FOR IMMEDIATE RELEASE | Saskatoon, SK  — Coconut Software, a leading provider of Intelligent Branch Solutions for banks and credit unions, today announced the release of M&A Without Disruption: A Modern Banker’s Launch Guide—a new executive e-book designed to help financial institutions address the operational, human, and customer experience challenges that most often cause M&A deals to underperform or fail outright.

Banking M&A activity is accelerating. 86% of bank executives now cite credit union acquisitions as their top competitive concern for 2026. And yet despite high deal volume, the integration outcomes remain troubling: over 83% of practitioners involved in failed M&A deals cite poor integration—not deal structure, pricing, or market conditions—as the primary cause of failure. Over 60% of M&A transactions miss their synergy targets, and the average bank loses 2–5% of its combined customer base post-merger, with losses exceeding 30% in cases of significant branch closures or service disruption.

“Mergers and acquisitions are exciting opportunities for growth, but they are also periods of intense risk,” says Katherine Regnier, CEO of Coconut Software. “Too often, banks and credit unions focus on financials and regulatory requirements while underestimating the human and operational impacts. The institutions that emerge stronger are the ones that treat people and experience as strategic assets, not operational afterthoughts.”

The Front End Is the Blind Spot Banks Can’t Afford

Most merger integration plans are built around back-end consolidation: core system migration, data mapping, security and API alignment. These are essential. But M&A Without Disruption argues that the customer-facing experience layer ( the tools members and branch staff interact with every day) is almost always addressed last, creating the gap where trust disappears, staff burn out, and customers quietly leave.

Bain & Company’s 2025 research shows NPS scores dropped 55% in a single quarter at one large bank merger, as customers experienced delays accessing accounts, online banking failures, and poor support response times. Meanwhile, McKinsey reports that banks standardizing the member experience pre-merger reduce post-merger service complaints by 20–30%.

“The experience layer isn’t a nice-to-have during a merger—it’s a risk mitigation strategy,” adds Regnier. “Deploy it first. Before your core goes live. That’s the playbook the most successful institutions are using.”

What’s Inside the Guide

M&A Without Disruption: A Modern Banker’s Launch Guide addresses the full scope of integration risk across three dimensions — and gives financial institution leaders actionable frameworks for each:

• The Tech Challenge: How to evaluate every vendor in the customer-facing tech stack before consolidation begins, including five critical questions every bank should be asking right now. The guide introduces the concept of the “experience layer” — technology that sits above the core, decouples from backend dependencies, and maintains member-facing continuity while migrations are underway.
• The Staff Challenge: Why culture clash, talent exodus, and employee experience disruption are the costs most integration plans underestimate — and how cross-functional governance, standardized workflows, and structured change enablement protect frontline performance when it matters most.
• The Customer Challenge: How to deploy a unified member experience from Day One, proactively manage branch transitions with lead time and clarity, and protect the advisor-client relationships that are the institution’s most valuable retention asset.

The guide also includes a phase-by-phase M&A playbook (pre, during, and post), and guiding principles for institution leadership.
