Mergers and acquisitions (M&A) are back on the corporate agenda. Private equity firms are sitting on record levels of dry powder. AI-driven deals are heating up. And more companies are hiring for corporate development roles. In short: the market is stirring after years of stagnation.
But here’s the harsh truth, up to 80% of mergers still fail to deliver their promised results.
So what’s going wrong?
The answer isn’t just in the numbers. It’s in the people.
The Overlooked Factor in Deal Success
Despite decades of data, deal failure rates have remained stubbornly high. Yet firms that focus on cultural integration and people strategy are 70% more likely to hit their revenue goals and 30% more likely to reach synergy targets.
The implication is clear: culture isn’t just a soft concept. It’s a business driver.
So why do so many organizations still get it wrong?
Too often, the financial and legal mechanics dominate the deal room, while the human side is treated as an afterthought.
“Listen Before You Lose Them”
One of the most actionable strategies for improving M&A outcomes is deceptively simple: listen.
Listening doesn’t always mean scheduling interviews. Start with what’s already available…employee reviews on platforms like Glassdoor, for example, can give early clues about what matters most to a workforce.
Leaders can also listen through managers. Conducting “stay interviews” with critical talent helps surface key motivators and potential flight risks before integration stress sets in.
And don’t stop listening once the deal is done. Follow-up culture surveys, manager check-ins, and office hours can help sustain trust throughout the post-merger phase.
But listening without action is worse than not listening at all. If people share concerns and nothing changes, it erodes trust. Even small actions, such as clear communication around benefit changes, can demonstrate to employees that their voices matter.
Middle Managers: The Forgotten Linchpins
Middle managers are often the glue between strategic intent and frontline execution. Yet in many deals, they’re left in the dark until announcement day and forced to manage both their own uncertainty and the emotional fallout of their teams.
That’s a mistake.
When middle managers aren’t empowered, they can’t help others. They become bottlenecks instead of bridges. But when they’re included early and equipped with the right tools and talking points, they become amplifiers of clarity and stability.
Give them a 30-minute preview before major announcements. Provide change management resources (like the Bridges Transition Model or the Kübler-Ross curve). And offer spaces, both formal or informal, where they can ask their own questions without judgment.
Three Critical Questions on Announcement Day
When a merger is announced, employees don’t care about your go-to-market strategy, at least not right away. They’re asking three simple, deeply human questions:
- Do I still have a job?
- Will my job be as good as before?
- Will I be treated fairly?
Failing to answer these clearly and transparently creates anxiety, and anxiety leads to attrition. If people are unsure whether they can pay their rent or keep their health coverage, they’ll start updating their résumés before the day is done.
And please: don’t say “nothing’s going to change.” It’s never true. Even if day-to-day tasks remain the same, the ownership, the strategy, and the emotional contract with the employer have shifted. Respect your people enough to be honest with them.
What’s Next for M&A?
Looking ahead, we’re likely to see more deals driven by talent, not just tech. AI-related “acquihires,” distressed business roll-ups, and founder retirements will continue to reshape the landscape.
Buyers who understand that talent is a value multiplier and not just a cost center, will have the upper hand. But they’ll need to prove they can manage that talent well, especially in times of uncertainty.
In the end, successful integrations aren’t about spreadsheets. They’re about people. And the most effective leaders are those who act like they care.
Act Like You Give a Damn
This isn’t just a catchy phrase; it’s the most important advice any leader can follow during an integration. Be visible. Be human. Be honest.
Hold office hours. Walk the halls. Say things like, “I care about how this affects you.” Because no matter how well a deal looks on paper, it’s people who determine whether it succeeds in real life.
