The M&A Checklist for Sustainable Growth

When talking about keeping a company growing and relevant in changing times executives can pick from one of three options. 

Obviously there won’t be one single company that picks only one of the three and they will go for a mix between the three but there is always going to be a question of resource allocation. Where do we focus most of the efforts? To which one of the three options is the opinion of the board the resources that come with that option are going to be skewed.

The first option is optimizing the existing business model by investing in tech that will streamline operations and have a direct impact on the bottom line. Basically there CAPEX and OPEX expenditure for the sake of cost reduction and OPEX optimization. In other words, continuous improvement and digital transformation. This option is the most popular as it is also the most urgent and the one which has the most predictable and short term outcomes. However this is not an option that will impact the top line, prevent disruption or add new revenue streams. This is, if you want the hygiene option. And in some industries like banking, telco, logistics or air travel, this option leads to a zero sum game. 

At the opposite end of spectrum boards have another option: innovation-led growth. Done right, this option creates new revenue streams, adds to top line growth and prevents disruption. But it is risky, has unpredictable and long term returns, hence it’s easy to see why this is not the darling of the options as it is OPEX intensive with unknown upside. 

However there is a third option that boards consider when wanting to grow the company. That is the M&A option. Yes it is resource intensive but it offers the promise (if done right) of predictable returns, adding of new revenue streams and disruption prevention. Also the stock market might not agree with the decision and the stock price will drop immediately after the acquisition is announced like it happened with Bayer when it announced the acquisition of Monsanto seeing its value plunge by $18 billion. 

As you can see the M&A option is not risk free, it’s not a silver bullet for growth, and data shows us that 70 to 75% of deals fail. But to increase the chances of success of an M&A it is advisable to be mindful of the following basic checklist:

1. Validate Strategic Fit Against Core Investment Themes. Every acquisition must reinforce your existing strategic direction. Evaluate whether the target aligns with your investment themes, core markets, or future growth vectors. Scrutinize the logic behind the deal—especially the assumptions around synergies. If the integration story feels optimistic or disconnected from reality, challenge it. Be brutally honest: does this deal deepen your competitive advantage, or simply create the illusion of growth?
2. Pursue M&A to Accelerate Competitive Strategy, Not Inflate Numbers. Use M&A as a tool to accelerate or deepen your existing competitive edge—not as a mechanism to bulk up revenue or earnings. Strategic alignment must always come before financial engineering. Avoid deals that look attractive on a spreadsheet but offer no clear path to reinforcing your long-term positioning. Opportunistic acquisitions that don’t clearly tie into your core strategy tend to under-perform over time.
3. Avoid Complexity That Dilutes Focus and Alienates Customers. Steer clear of acquiring companies with overly complex product portfolios or bloated organizational structures. These deals often result in long, expensive integration processes that confuse customers and distract your teams. Make sure to assess how the acquisition impacts your customer experience—will it improve your capabilities and service, or risk churn? Additionally, audit the target’s ESG profile and brand reputation; you’re inheriting their legacy, for better or worse.
4. Don’t Acquire a Peer—Avoid Power Struggles. Acquiring a company of equal size often triggers power struggles that stall momentum and delay value creation. Integration becomes a political battle over leadership, culture, and control. To avoid this, ensure the post-merger leadership structure is defined clearly within the first 90 days. Without clarity, the organization risks descending into strategic paralysis.
5. Prioritize Cultural Alignment from Day One. Culture clashes are one of the most common—and costly—reasons deals fail. Conduct a culture diagnostic during due diligence and integrate the findings into your M&A planning. Consider appointing a dedicated culture integration lead, empowered to make real decisions. Without alignment on how people operate and make decisions, no amount of financial or operational planning will save the deal.
6. Develop the Integration Plan Early—Not After the Deal Closes. Integration planning should start during the due diligence phase, not after the ink dries. Define clear milestones and timelines so both sides know what success looks like on Day 1, Day 90, and beyond. A deal without an execution roadmap is a strategy in name only.
7. Set Measurable Synergy Targets—and Own Them. Define specific, quantifiable targets for both cost synergies and revenue uplift. These should be more than headline figures—they must be owned by accountable leaders with timelines, KPIs, and real consequences for under-performance. Execution discipline is what separates high-performing deals from value-destroying ones.
8. Lock in Key Talent Before You Lose Them. People are your most fragile asset post-acquisition. Identify key individuals early and put retention strategies in place—particularly in businesses where IP, client relationships, or institutional knowledge drive value. Communicate clearly about roles, career paths, and what the future looks like. Ambiguity breeds attrition.
9. Evaluate IT Integration Complexity and Tech Debt. Technology integration is a common stumbling block. Assess the compatibility and scalability of systems during diligence. Mismatched infrastructure or legacy tech can delay integration and inflate OPEX. Unless there’s a clear modernization path, don’t absorb tech debt that drags down your innovation velocity.
10. Define the Brand Architecture Post-Deal. Your brand strategy matters as much as your financial strategy. Will the acquired company be integrated into your master brand, operate as a standalone, or carry an endorsed identity? Confusion here leads to diluted messaging, customer skepticism, and internal misalignment.
11. Preempt Regulatory and Antitrust Risks. Regulatory friction can derail even the most strategically sound deal. In regulated industries such as healthcare, finance, and telecom, anticipate challenges early. Conduct a thorough risk assessment and factor in potential delays and concessions. Don’t underestimate the time and cost of navigating regulatory approvals.

To ensure M&A decisions are well-vetted and strategically sound, consider instituting a “Go/No-Go” discipline. Create a deal review committee that includes internal skeptics—such as CFOs, risk officers, or board members—who are empowered to challenge assumptions and rigorously test the deal’s validity before moving forward. In the committee’s first meeting, conduct a “pre-mortem” analysis. Pose the question: If this deal fails, what will have gone wrong? This proactive exercise is invaluable for identifying potential blind spots and mitigating risks early in the process.
