What the 14% Who Succeed Do Differently

MERGERS & ACQUISITIONS SERIES
While 86% of acquisitions fail to deliver value, 14% achieve remarkable success. Here are the five disciplines that separate winners from losers.
In our last post, we revealed how acquisitions silently bleed value through information silos (30% of revenue), trust breakdowns (50% higher attrition), and cultural misalignment ($200-600M annually). The hidden tax that compounds daily while steering committees show green.
But here's what gives me hope: this isn't inevitable.
PwC's analysis of Fortune 1000 companies found that 14% achieved significant success across strategic, operational, AND financial goals. While everyone else was explaining away "integration headwinds" to their boards, these companies were actually capturing the value they promised.
So what are they doing that the other 86% aren't?
The answer isn't more sophisticated synergy models or better project management tools. It's five fundamental disciplines that sound simple but require relentless execution.
1. They Protect the Base Business Like Their Deal Depends On It
Because it does.
Here's a stat that should be tattooed on every integration leader's forehead: 72% of successful deals avoided the "year-one revenue dip" versus only 33% of unsuccessful deals.
The principle is unforgiving: no amount of synergies compensates for top-line disruption.
Yet most integration plans treat "maintain current business performance" as a given while pouring all their energy into transformation initiatives. Then act surprised when customers defect and revenue slips.
The 14% flip this script. They start every synergy meeting with a core business performance update. One healthcare integration leader made this her non-negotiable: "Before we discuss any integration topic, we review this week's performance metrics."
This simple practice does two things:
- It keeps everyone focused on what actually matters (business outcomes, not project milestones)
- It surfaces problems while they're still small enough to fix
They use a stakeholder lens instead of functional swim lanes. Not "How's the IT integration going?" but "Can our customers still get served effectively? Can our employees still do their jobs? Are our partners still confident in us?"
Every integration decision gets tested against one question: "Will this help or hurt current business performance?" If you can't answer clearly, you're probably creating risk.
2. They Build Trust as a Strategic Weapon
High-trust workers are 1.8x more motivated to work harder and deliver 2.3x higher efficiency. But trust doesn't transfer with the stock certificates—it has to be rebuilt from scratch.
The successful integrators understand this. They map the trust landscape within the first 100 days, before friction emerges. Not with annual engagement surveys that arrive too late. Real-time pulse checks that identify where trust is breaking down by role, region, and team.
But here's the critical part most leaders miss: they use closed-loop feedback to demonstrate that employee voices lead to visible action.
Not quarterly action. Not "we're taking this under advisement." Visible changes within days that show people their input matters.
One company using this approach identified an impending attrition wave in their sales organization. They immediately adjusted comp plans, clarified territories, and assigned executive sponsors. Result: millions saved in retention costs and a prevented customer crisis.
The winners also recognize that managers are "trust multipliers." A high-trust relationship with your manager can compensate for organizational uncertainty. A low-trust relationship accelerates attrition. So they invest accordingly—ensuring managers have the information, authority, and support to build trust with their teams.
3. They Communicate Relentlessly (And Still Think They're Under-Communicating)
If you feel like you're overwhelming employees with communication, you're probably doing it right.
Over 50% of merger integration difficulties have roots in communication problems—making this the highest-leverage intervention available. Yet most integration leaders dramatically undercommunicate.
The 14% provide weekly updates through multiple channels. They maintain high visibility throughout the pre-close "dark period" when competitors attack and employees get nervous. They ensure Day 1 includes high executive touch at every level—not "we'll get to your team in a few weeks."
They also do something most don't: they create closed-loop feedback mechanisms. Each week, they publish:
- The top 3 concerns or questions raised by employees
- The specific actions being taken in response
- Who owns each action and when it will be complete
This does two things simultaneously: it shows you're listening, and it demonstrates that feedback leads to action. Both are essential for maintaining trust when everything else feels uncertain.
One integration leader told me: "I thought we were over-communicating. Then we did a pulse survey and found that 60% of employees still didn't understand the integration timeline. We doubled our communication frequency after that."
The absence of information gets filled with anxiety, rumors, and worst-case scenarios. The winners fill that vacuum with truth.
4. They Make Synergy Capture a Line Responsibility
Here's where most integrations go wrong: they treat synergy capture as a corporate function responsibility instead of a line operating accountability.
Successful integrators do the opposite. They maintain value-based governance with dedicated teams tracking synergies through P&L for the full two-year window. They don't pivot responsibility to corporate functions prematurely. They hold line leaders accountable in annual operating plans and budgets.
And they move fast. The best deliver 50%+ of public synergy targets in year one.
Why does this matter? Because the longer you take to capture synergies, the more the organization starts to question whether they're real. Momentum stalls. People start protecting their turf. The integration becomes "that thing we're still working on" instead of "the transformation that's already delivering results."
One tech company created a simple rule: every synergy on the master list had an owner, a timeline, and a monthly review with the CEO. No exceptions. If a synergy wasn't tracking to plan, the owner had to present the recovery plan or take it off the list.
This level of accountability feels intense. But that's what separates the 14% from everyone else—they treat synergy capture with the same rigor they bring to running the business.
5. They Invest in Cultural Integration Like the Deal Depends On It
Because it does.
Companies with aligned corporate cultures deliver total shareholder returns 3x higher than those with misaligned cultures. Yet 60% of practitioners admit they wish they'd spent MORE on culture and change management.
The winners don't make this mistake. They conduct cultural assessments during due diligence—not after close when the damage is done. They identify "non-negotiable" behaviors from day one and make them explicit. Not vague values statements like "we value collaboration." Specific behaviors like "we make decisions in 48 hours or escalate."
Then they hard-wire those behaviors into the operating model:
- Compensation and incentives reward the right behaviors
- Training and resources help people adapt
- Progress is measured as rigorously as financial synergies
- Leaders who can't or won't model the culture are removed
One enterprise software company did something brilliant: they created "culture champions" in each business unit—respected leaders who modeled the target behaviors and helped their teams navigate the transition. Not HR consultants. Line leaders with credibility.
The investment paid off. Their attrition rate in year one was 12% versus an industry average of 33%. And employee engagement scores actually improved during integration—something almost unheard of.
The Pattern That Connects Everything
Look at these five disciplines and you'll notice something: they're all about reality over rhetoric.
The 14% who succeed don't rely on org charts and dashboards showing green. They create mechanisms to surface what's actually happening:
- Real-time trust metrics, not annual surveys
- Weekly performance reviews, not quarterly retrospectives
- Closed-loop feedback, not one-way announcements
- Line accountability, not staff function ownership
- Cultural behaviors, not values posters
They understand that integration doesn't fail because of inadequate planning. It fails because of inadequate information about what's really happening when the plan meets reality.
The distance between what you're hearing in steering committee meetings and what's happening on the ground—that's where $1.5 trillion in value disappears every year.
What This Means for Your Integration
If you're leading an integration right now, ask yourself:
- Do you actually know where trust is breaking down? Not in aggregate scores, but specific teams, specific managers, specific friction points?
- Can your people tell you the truth about what's blocking them without fear of consequences?
- Are you learning about problems from your steering committee dashboard, or are you hearing about them while they're still fixable?
- Is synergy capture owned by line leaders who wake up thinking about it, or is it a corporate function tracking a spreadsheet?
- Did you invest as much in cultural integration as you did in IT systems integration?
The answers to these questions separate the 14% from the 86%. The difference isn't luck or market conditions. It's discipline, focus, and relentless commitment to surfacing reality.
In our final post in this series, we'll give you the specific playbook for the next 100 days—the actions that separate preserving value from watching it evaporate. Because this isn't about understanding the problem. It's about actually doing something different.
The ground truth is there. Your people know what's really happening, what's blocking them, what would make them stay. The question is: are you creating the channels to hear it before it's too late?
