Niall White – $10B in Deals: Post-Acquisition Reality Check

In this episode, James Kennedy sits down with Niall White, corporate finance expert and founder at Capstack, to unpack what really determines success after the deal closes. Drawing on a career spanning BDO (Dublin & London), Barclays Capital (funding marquee PE buyouts), and in-house M&A at an Irish PLC, Niall explains why most value is won – or lost – during integration, not at the signing ceremony. They cover how to prepare a founder-led company for sale, structure earn-outs that actually work, and the people/controls you must have in place before, during, and after a transaction.

James Kennedy sits down with Niall White, corporate finance expert and founder at Capstack, to unpack what really determines success after the deal closes. Drawing on a career spanning BDO (Dublin & London), Barclays Capital (funding marquee PE buyouts), and in-house M&A at an Irish PLC, Niall explains why most value is won – or lost – during integration, not at the signing ceremony. They cover how to prepare a founder-led company for sale, structure earn-outs that actually work, and the people/controls you must have in place before, during, and after a transaction.

About Niall White

A chartered accountant with 25+ years in mid-market and large-cap transactions, Niall has advised and financed billions in deals across Europe, served on in-house corporate development teams, and now provides fractional CFO & M&A readiness support through Capstack. His sweet spot: helping owner-operators professionalize, navigate diligence, and integrate smoothly so both buyer and seller realize the value they negotiated.

What You’ll Learn

  • Post-Acquisition Integration that Works: How to bolt on founder-led businesses to PLC/PE platforms and hit the synergy case.
  • “Value & Control” Test: Shifting dependency from the founder to the company (contracts, systems, management depth).
  • Earn-outs without Regret: When to use them, how to avoid misaligned incentives, and why many founders rush for early exit.
  • Sale-Readiness Playbook: From handshake revenues to signed service contracts, MI/BI upgrades, and CFO function uplift.
  • Buyer Lenses: Trade vs. private equity – what each overpays for, and why scale (e.g., €5m EBITDA) is inherently more defensible.
  • Hidden Asset: Your Data: Monetization lessons (e.g., EV-charging datasets) beyond classic EBITDA × multiple valuation.

Episode Highlights

  • Businesses are about people. If you don’t have the right people and controls, the spreadsheet won’t save you.”
  • “Buyers pay for autonomy – a company that runs without the founder, not because of the founder.”
  • “If cash comes in wrong at the start – no contracts, weak MI – the trickle-down pain is massive in diligence and integration.”
  • “Bigger isn’t just vanity: scale absorbs shocks and expands your buyer universe.”
  • “Earn-outs work only when the vision and incentives are genuinely aligned.”

More about Niall’s role

Through Capstack’s CFO Solutions, Niall embeds as a fractional CFO to:

  • Prepare businesses for sale or investment (commercial contracts, KPIs, dashboards, close cadence).
  • Run finance workstreams during diligence (QoE support, data rooms, buyer Q&A triage).
  • Lead the first 100-day integration (reporting, controls, synergy tracking, team design).
