Why the Thesis Keeps Surviving and the Execution Keeps Failing

The global payments sector is in the midst of its most consequential consolidation wave in a decade. Deal activity has accelerated even as valuations have re-rated lower across the industry. Yet the most instructive lesson, that scale alone does not create value, keeps being relearned at enormous cost.

In payments M&A, the deal thesis is mostly accurate. What destroys value is the distance between the thesis and the operating model of the combined entity, and that distance is almost always visible before signing to anyone willing to look.

The Pattern That Keeps Repeating

The Seduction of Scale

Every major payment M&A cycle begins with the same logic: combine merchant acquiring with issuing, add software, achieve end-to-end control of the payment flow, and extract margin at every layer. It is a coherent thesis. FIS articulated it in 2019 when it paid roughly $43 billion for Worldpay[1]. Global Payments articulated it with TSYS. Fiserv did the same with First Data.

What the thesis misses is that payments businesses run on fundamentally different operating rhythms, technology architectures, and client relationships depending on which part of the stack they serve. Merchant acquiring is a volume game built on thin margins and massive operational scale. Issuer processing is a long-cycle enterprise software business built on contractual depth and switching costs. Forcing them into a single P&L does not create synergy, it creates organizational confusion and capital misallocation.

The 2025 Global Payments / FIS strategic asset swap, effectively the industry unwinding the consolidation strategy of 2019, is strong evidence that the original integration thesis failed to create value. Global Payments re-acquired Worldpay at a $24.25 billion enterprise valuation while divesting its Issuer Solutions business to FIS for $13.5 billion[2], with FIS using its Worldpay stake plus roughly $8 billion of debt to complete the exit[3]. The market reached the same conclusion well before the swap: payments-sector equities, including FIS and Global Payments, fell roughly 30–40% from early-2021 levels as the sector matured and multiples compressed.[4]

This repricing is a sector backdrop, not the core problem. Median fintech revenue multiples have compressed from roughly 7.7x at the 2021 peak to about 4.2–4.7x today, with payments names now trading around 8–12x EV/EBITDA[5] — a fraction of growth-era levels. But the lower-multiple environments only sharpen the real issue: with little multiple expansion available to rescue a deal, value has to be created operationally or not at all. That puts the entire weight of the return on whether the deal thesis is realized — and that is where diligence and integration, not valuation, decide the outcome.

Where Value Is Actually Created

Payments deals that consistently deliver returns share three characteristics that have nothing to do with headline size.

1. Strategic clarity before signing. Successful acquirers who know precisely which capability they are buying and why they cannot build it faster or more cheaply. They are not buying scale, they are buying a specific client relationship, a regulatory license, a technology architecture, or a data asset. Stripe’s $1.1 billion acquisition of Bridge was not a scale play; it was a precise bet on stablecoin infrastructure as the next payment rail.[6]
2. Integration reality is priced into the deal. Acquirers who lose money consistently underestimate the cost and timeline of technology integration, overestimate how quickly revenue synergies will materialize, and fail to account for the client attrition that occurs when two organizations in parallel sales motions begin competing for the same relationships. These risks are not unknowable, they are visible in diligence to anyone asking the right operational questions.
3. Retention of what made the target valuable. In payments, a disproportionate share of value sits with a small group of leaders and a concentrated book of customers. Best-in-class buyers explicitly price and structure around people-and-client-concentration risk, shifting consideration into earn-outs and retention tools where a handful of relationships drive a large share of revenue. Because losing even one or two key clients or executives can materially impair valuation. Leadership retention agreements and shared incentive pools should be treated not as administrative details, but as the primary mechanism for protecting deal value over the first 24 months post-close.

A Framework for Value Creation Across the Deal Lifecycle

Phase One — Pre-LOI: Quality Before Commitment

• Verify active contracted revenue — not reported client counts.
• Assess regulatory license health independently.
• Complete technology-integration scoping before exclusivity.
• Identify the key relationships the business cannot survive losing.

Phase Two — Diligence to Close: Price the Integration, Not Just the Business

• Model integration costs as a deduction from deal value, not a post-close line item.
• Stress-test revenue-synergy assumptions against historical churn data.
• Map technology-stack dependencies, including processing agreements that do not transfer.
• Negotiate leadership retention before the LOI anchors the terms.

Phase Three — Day 1 to Day 100: Protect Value Before Creating It

• Day-one client communication that is personal, specific, and senior-led.
• Freeze the sales motion. Do not reorganize until clients are stabilized.
• Establish a single, dedicated integration owner with direct CEO access.
• Set synergy milestones at 30, 60, and 90 days — not year one.

Execution Is the Strategy

The global payments consolidation wave of 2025–2026 will produce both its winners and its write-downs. The difference will not be determined by deal size, valuation discipline, or the quality of the investment-banking advice. It will be determined by whether the acquirer understands, prior to signing, exactly what they are buying, what it will cost to integrate, and how they plan to protect the value that exists before they begin creating new value on top of it.

In payments M&A, execution is not an operational detail that follows strategy. It is the strategy.

How A&M’s Corporate Transactions Group Can Help

Alvarez & Marsal’s Corporate Transactions Group works with acquirers, sellers, and investors across every phase of the payments M&A lifecycle. Our approach is built on the principle this paper describes: execution is where value is created or destroyed, and the quality of that execution is set by decisions made well before closing.

We bring senior, sector-experienced operators — not generalist advisors — to the specific moments in a transaction where the risk of value leakage is highest. We work at the intersection of strategy and operations, where the distance between thesis and execution is either closed or becomes the write-down. Whether you are evaluating your first acquisition or managing a portfolio integration, we bring sector depth and operational discipline to protect and accelerate value from pre-sign through close.
