Change Management Insights From Recent Mergers

M&A activity is accelerating in 2025 with deals like Aviva 's £3.7bn Direct Line takeover and the $22.5B ConocoPhillips Marathon Oil merger reshaping industries. But did you know that 33% of acquired employees leave post-acquisition, and culture misalignment is the #1 reason acquisitions fail? AI ALPI analyzed 75+ major acquisitions this quarter and found that HR involvement from day one of M&A discussions increases success rates by 40%. The most successful deals all shared one thing: CHROs were equal partners with CFOs during due diligence. Key insights for HR leaders: → Pre-merger involvement is crucial: It makes good business sense to involve HR earlier because we provide a different point of view and will ask different questions → Culture fit predicts success: Companies with high employee-engagement scores are 3x more likely to achieve post-merger synergies. Smart acquirers review Glassdoor scores before making offers ↳ 65% of 2025's healthcare M&A deals focus on therapeutic specialization rather than scale, requiring careful talent retention strategies → Speed matters: The integration timeline should be as short as possible.

I've led 17 M&A integrations. Here are the 5 critical lessons I've learned: 1. 𝐋𝐞𝐚𝐝𝐞𝐫𝐬𝐡𝐢𝐩 𝐚𝐭 𝐭𝐡𝐞 𝐓𝐨𝐩 𝐑𝐞𝐪𝐮𝐢𝐫𝐞𝐬 𝐚 𝐃𝐢𝐟𝐟𝐞𝐫𝐞𝐧𝐭 𝐌𝐢𝐧𝐝𝐬𝐞𝐭 Traditional leadership development fails during integration. Why? Because uncertainty demands a different kind of leader. Through these integrations, I learned to identify leaders who: • Thrive in ambiguity • Adapt their style instantly • Read situations before they escalate • Drive change without losing people 2. 𝐋𝐢𝐬𝐭𝐞𝐧 𝐚𝐧𝐝 𝐋𝐞𝐚𝐫𝐧 𝐁𝐞𝐲𝐨𝐧𝐝 𝐭𝐡𝐞 𝐍𝐮𝐦𝐛𝐞𝐫𝐬 The true value isn't just in products and revenue. Some of the best discoveries can come from understanding what made the acquired company exceptional in their: • Human resource strategies • Cultural dynamics • Inclusion practices These are often the hidden gems that should reshape the acquiring company, not just the other way around. 3. 𝐈𝐧𝐭𝐞𝐠𝐫𝐚𝐭𝐞 𝐰𝐢𝐭𝐡 𝐇𝐞𝐚𝐫𝐭 𝐚𝐧𝐝 𝐌𝐢𝐧𝐝 Success isn't just about systems integration. It's about: • Seeing the faces behind the spreadsheets • Understanding transferable skills • Creating meaningful roles that honor expertise • Walking in their shoes through the transition 4. 𝐁𝐞 𝐚 𝐒𝐭𝐫𝐚𝐭𝐞𝐠𝐢𝐜 𝐏𝐚𝐫𝐭𝐧𝐞𝐫 𝐭𝐨 𝐋𝐞𝐚𝐝𝐞𝐫𝐬𝐡𝐢𝐩 I've watched great managers crumble during integration. And seen unexpected leaders emerge from the chaos. Here’s what differentiates: • Challenge assumptions constructively with market intelligence • Balance short-term wins with long-term strategic goals • Support decision-making with clear risk/benefit analysis • Act as a bridge between acquired and acquiring leadership teams 5. 𝐋𝐢𝐦𝐢𝐭 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐃𝐢𝐬𝐫𝐮𝐩𝐭𝐢𝐨𝐧 While integration is complex, maintaining business momentum is critical. Focus on: • Preserving customer relationships • Maintaining operational excellence • Protecting revenue streams • Keeping top talent engaged Through these integrations, I've learned that success isn't written in manuals. It's carved out in moments of uncertainty. The best strategies emerge when we dare to look beyond traditional playbooks. And see the full picture: products, people, and possibilities. 👉 To my fellow Corporate Development and M&A experts: What crucial lessons would you add from your integration experiences? Share them below so we can keep learning from each other.

When doing any M&A - are you purchasing the intellectual property or the business? Because if you're buying ANYTHING more than the intellectual property, trust is at the core of the integration. You can (maybe) integrate systems in 90 days. Integrating trust takes a whole lot longer. One of the most overlooked risks in M&A? The human one. I’ve been through multiple integrations, due diligence cycles, and post-close transitions. And I can tell you: spreadsheets may win the deal, but it's trust, communication, and culture that determine whether the value actually materializes. Circling back to one of my previous posts - it is also making sure the "say" and the "do" match - ALL the way back to the initial due diligence. Here's what often gets missed: 🔹 People interpret silence as threat - and in the absence of information will create their own story - which is often significantly worse than the truth! Communication isn't just a courtesy—it's risk mitigation. 🔹 Culture is an operating system. Every team has embedded ways of working. If you force alignment without understanding those patterns, you may inadvertently shut down what made them successful in the first place. 🔹 Integration is emotional. Titles shift. Power moves. Identities blur. Benefits change. The process isn’t just technical—it’s deeply personal. And without a strategy for that, and a proactive change plan (that is HEAVY on the communication) you’re leaving value on the table. The most successful integrations I’ve supported had three things in common: 🧩 A shared leadership narrative grounded in purpose and clarity. 🧩 Early identification of cultural hotspots—not just red flags, but areas of pride and strength. Coupled with the understanding that the acquired organization may often have things to teach the buying organization! 🧩 A deliberate, empathetic, and transparent approach to change management—because speed without humanity breeds resistance. M&A is an incredible opportunity to reset, refocus, and rebuild stronger. But only if the people inside the business believe they have a future in the new version. The real synergy? It’s not just in the balance sheet. It’s in the belief system. I'd love to hear from others—what’s something you’ve seen work (or not) when two organizations become one?
