M&A in 2026: When Merging Makes Sense

In 1994, Congress passed the Riegle-Neal Interstate Banking and Branching Efficiency Act, effectively dismantling the last big barriers to interstate bank mergers. What followed was one of the most consequential waves of banking consolidation in US history. Between 1985 and 2000, the number of commercial banks fell from 14K to under 8K due mostly to mergers. A similar window may be opening today, but it may not stay open long. After a multi-year lull driven by rising interest rates, depressed asset valuations, and regulatory friction, bank M&A shot up in 2025. According to S&P Global Market Intelligence, 181 US bank deals were announced last year, up 45% from 2024. Meanwhile, the Federal Reserve Bank of Kansas City reported 127 completed community bank mergers in 2025, the highest total since 2021.Finally, the Federal Reserve noted it is actively reviewing "merger and acquisition and de novo chartering processes for community banks, including streamlining applications and updating our competitive analysis framework." Indeed, recent bank mergers have been approved in half the time compared to the previous regime.For community financial institutions (CFIs) weighing M&A in 2026 and beyond, the current environment is as favorable as it has ever been. However, favorable conditions alone don't make a merger successful. Here are the key questions to ask if you’re considering a merger or a sale.Question 1: Why a Merger?The most common mistake in banking M&A is pursuing a deal without a strategic rationale. Scale alone is not a strategy. Institutions that consistently extract value from mergers enter with a clear thesis, such as a specific geography they want, a talent gap they're trying to fill, a tech capability they need, or a deposit base that complements their own.According to analysis from Reed Smith, the most active M&A catalysts in 2025 and 2026 include scaling for digital transformation and AI, accessing broader customer data, and geographic footprint expansion. Kansas City Fed data support the geographic factor: in over 50% of completed bank mergers, the acquirer expanded into new operating markets via the purchase.Before engaging an advisor or approaching a target, articulate your strategic rationale in a single paragraph. What does this deal give you that organic growth cannot provide quickly enough? If the answer is vague, that's a signal to slow down and sharpen the thesis first.Question 2: Does the Culture Fit Make Sense?The financial due diligence behind a CFI merger is rigorous: loan book quality, CRE concentrations, deposit composition, interest rate risk, capital adequacy, and tech compatibility all require careful review. Yet, integration failures (e.g., a deal that closed successfully but quietly underperformed) always trace back to cultural issues rather than balance sheet problems.For CFIs, culture is not a soft concept. It includes how lending decisions get made, how staff are managed, how exceptions are handled, how the institution relates to its community, and whether leadership styles are compatible. A merger between two institutions with fundamentally different credit cultures can create more risk than either institution would carry independently.Staff attrition during regulatory review and integration periods is a documented cost — one that Fed Vice Chair Bowman noted as a consequence of delayed approvals that "run two institutions in parallel" for long periods.Build cultural assessment into early-stage diligence, not as an afterthought. This means structured conversations with target leadership about decision-making, staff retention, community involvement, and credit philosophy before a term sheet is signed. Where big cultural gaps exist, factor in integration costs and timelines into your deal model.Question 3: Do We Have a Full Picture of the New Regulatory Environment?The recent shift in the banking regulatory climate is well-documented. The 2024 merger review guidelines that added friction to the approval process have been rescinded. The FDIC also withdrew its more stringent M&A policy statement. Since then, the OCC and Fed have been processing applications faster. As noted above, recent deals have cleared in half the time similar transactions required under the prior administration.Yet, streamlined does not mean rubber-stamped. The core statutory review factors remain: competitive effects, financial and managerial resources, future prospects of the combined institution, convenience and needs of the communities served, and compliance with BSA/AML requirements. Institutions with unresolved supervisory issues, weak CRA performance, or meaningful CRE concentrations will still face scrutiny.As industry observers have noted, the current pro-merger regulatory stance may not last indefinitely. The political window is most favorable through 2026–2027, before election dynamics reintroduce uncertainty. CFIs that have been considering a deal have reason to act quickly and with intention.Engage regulatory counsel early, ideally before approaching a target, to understand your institution's standing with your primary federal regulator. A less-than-satisfactory exam rating or an open Matter Requiring Attention (MRA) can complicate or delay approval even in a favorable environment. Knowing your regulatory posture in advance allows you to address issues proactively rather than mid-process.Question 4: Could We Build This Ourselves?The conventional wisdom in banking M&A has often been to pursue scale. However, Kansas City Fed data tells a different story. Bank sellers in 2025 had median annual loan growth of 0.5% and core deposit growth of 0.4%, compared with 4.7% and 3.8% for acquirers.The gap in profitability was equally striking, with sellers averaging just 0.6% ROAA, compared to 1.2% for buyers. In many cases, the most valuable thing a smaller institution offers isn't size; it's a niche commercial portfolio, a strong SBA lending practice, digital infrastructure that would take years to build organically, or a geographic presence in a key underserved market.The banking tech stack is more important than ever. As Reed Smith noted, banks are actively pursuing acquisitions to accelerate digital transformation and build out AI capabilities, spreading tech investment costs across a larger base while accessing broader customer data.For a CFI weighing a smaller target, the question worth asking is what it would cost us to build this ourselves and how long it would take? A smaller target with a strong book and low CRE concentration may be a better risk-adjusted value than a bigger bank with overlapping geography and a weaker deposit franchise.Question 5: Are We M&A-Ready Right Now?Whether a CFI is actively pursuing a deal or simply keeping its options open, M&A readiness is worth investing in. Institutions with clean data, documented procedures, strong governance, and up-to-date compliance move through due diligence faster, are more credible to potential partners, and close on better terms.Meanwhile, banks that scramble to organize financials, resolve open audit findings, or document core processes mid-diligence signal operational risk, which acquirers also price into their offers. M&A readiness that makes a CFI an attractive acquirer also makes it a more attractive acquisition target, which matters for boards.Either way, the M&A groundwork is the same on either side of the table: clean data, strong governance, well-documented processes, and a clear picture of the institution's financial position and risk profile.Conduct an internal M&A readiness assessment even if no deal is imminent. Are your call report data and financial records audit-ready? Do you have documented credit policies, underwriting standards, and risk management procedures? Are there any open supervisory matters that need to be resolved? Institutions that invest in readiness now are better positioned to act quickly.Are We Ready to Act with Clarity?The Riegle-Neal era of the 1990s is instructive because it shows us what happens when a regulatory window opens, and institutions aren’t prepared to act. The mergers and acquisitions that thrived were not necessarily the ones that moved fastest, either. They were the ones who moved with clarity about what they wanted, discipline in how they evaluated it, and rigor in their integration. The current environment creates a genuine opportunity for CFIs to expand, acquire capabilities, find a stronger partner, or simply review their options. That begins with an honest internal assessment of strategy, readiness, and whether a merger is actually the right path forward. For some institutions, the answer will be yes. For others, the most valuable outcome may simply be greater clarity about what real, lasting growth requires.
