Best Practices for Team Communication in M&A

Effective communication can make or break your M&A deal. Research shows that poor communication leads to delays, increased costs, and even failed mergers. Here's how you can avoid those pitfalls and ensure success:

• Start Early: Plan communication before the deal is announced to reduce uncertainty and prevent rumors.
• Map Stakeholders: Identify everyone impacted - employees, investors, customers - and tailor your messaging to their needs.
• Align Messaging: Keep internal and external messages consistent to build trust and avoid confusion.
• Use Technology: Secure communication platforms, like Virtual Data Rooms (VDRs), protect sensitive data and streamline collaboration.
• Address Culture: Open communication about differences in work styles and values can prevent cultural clashes.
• Post-Merger Communication: Regular updates, feedback channels, and knowledge-sharing ensure long-term success.

Why this matters: Companies with strong communication strategies are 3.5 times more likely to retain employees and achieve their financial goals during M&A. Start early, stay transparent, and keep all stakeholders informed.

A People First Approach to M&A Communication

Setting Up Communication Structure Early

Begin M&A communication well before any public announcements to align teams and establish a clear communication framework. This early planning focuses on three key steps: identifying stakeholders, streamlining messaging, and complying with legal requirements.

Timing is everything - communication planning should ideally start just before the deal is signed. Why? It helps avoid the "information vacuum" that David Olsson, Managing Director of the Institute for Mergers, Acquisitions & Alliances (IMAA), warns about:

"And as soon as you have a vacuum, gossip and rumors and everything else can come into play".

Mapping Key Stakeholders Before Announcements

Stakeholder mapping is the backbone of any effective M&A communication plan. Companies that prioritize this step are 30% more likely to meet their financial objectives during mergers. The process involves building a detailed list of everyone who needs updates about the transaction.

Internal stakeholders include employees, executives, board members, and union representatives. External stakeholders range from investors and customers to suppliers, regulatory agencies, community groups, and media contacts. Each group requires tailored communication to meet their specific needs.

A practical way to approach this is by using a stakeholder map - a grid that categorizes stakeholders based on their interest in the M&A and their influence over its outcome. For example:

• High-interest, high-influence stakeholders (e.g., key executives, major investors): Require frequent, detailed updates.
• Low-interest, low-influence stakeholders: Need only occasional summaries.

"Stakeholder engagement isn't just communication - it's strategy. Mapping stakeholders clarifies where to focus energy. Targeted messaging strengthens relationships and secures commitment." – Alec Gardner, Human Resource Collective

This map should be updated regularly as new stakeholders emerge or priorities shift.

Coordinating Internal and External Messages

Aligning internal and external messaging is crucial to prevent confusion or trust issues during the M&A process. When internal and external narratives don’t match, it can lead to mistrust and derail progress.

To ensure consistency, the communication team must collaborate closely with the deal team. This partnership helps avoid situations where employees hear major news from outside sources, which can damage morale and trust.

Develop pre-approved response templates and ensure leaders deliver consistent messages across all channels. Christopher Kummer, founder and CEO of IMAA, emphasizes the value of direct leadership involvement:

"I think it's a matter of leadership to go there and deliver this message yourself, even if it's not a nice one, as sad as it is".

By crafting a unified narrative, organizations can reduce rumors and build trust among stakeholders.

Following Legal and Confidentiality Rules

Legal compliance is the foundation of any M&A communication strategy. Legal teams must review all messages, enforce non-disclosure agreements (NDAs), and centralize communications to protect sensitive information.

A small, focused communication team - comprising legal, HR, senior management, and IT representatives - should handle all M&A-related messaging. This ensures that all angles are covered without compromising confidentiality.

External parties like suppliers, consultants, and advisors must also sign NDAs before accessing any transaction-related details. This safeguards sensitive information and minimizes risks.

Striking a balance between transparency and confidentiality is critical when addressing employee concerns. Employees deserve honest answers about how the M&A might affect them, but certain details must remain confidential until the right time for disclosure. Legal counsel can help craft messages that respect both needs.

Finally, planning for the post-closing announcement is just as important. Coordinating with all involved parties ensures a unified and controlled message when the deal goes public, reducing the risk of mixed signals or market instability.

Early, structured communication sets the stage for navigating the entire M&A process smoothly.

Creating Cross-Department Communication Teams

Cross-department teams are a cornerstone of successful mergers and acquisitions (M&A). These teams ensure that all business functions remain aligned and connected throughout the process. Jessica Ciccozzi, Founder and Director of East Executive, highlights the importance of prioritizing people in M&A:

"In 2025, the true value of M&As won't lie solely in tech synergies - people synergies will be the key to capitalizing on deal investments. Only by prioritizing people can organizations fully realize the true strategic deal value and achieve long-term success."

By fostering collaboration across departments, organizations can create a structure that keeps everyone informed and working toward shared goals.

Including Representatives from All Departments

To build effective cross-department teams, it's vital to include representatives from key areas like HR, legal, IT, senior management, and operations. Each department brings unique perspectives and expertise, ensuring that no critical aspect is overlooked. Clearly defining roles within the team helps prevent duplication of effort while addressing all communication needs. For example, during one merger, 1,500 employees collaborated to co-create a unified mission, paving the way for a smooth integration process.

Controlling Access to Sensitive Information

When dealing with sensitive information, strong security measures are non-negotiable. Role-based access controls tailored to each team member's responsibilities can help limit exposure to confidential data. Virtual data rooms (VDRs) equipped with controlled access provide a secure environment for sharing sensitive documents. A lack of proper access controls in a high-profile case once resulted in severe financial penalties, underscoring the importance of robust protocols. Regularly monitoring and auditing data access adds another layer of security and accountability.

Using Secure Collaboration Platforms

Technology plays a key role in ensuring both security and efficiency in cross-department communication. Collaboration platforms with strong encryption and multi-factor authentication minimize the risk of unauthorized access. Features like detailed audit trails, which track document access and edits, enhance transparency and support compliance efforts. Secure "clean rooms", where independent parties can safely analyze sensitive data, have also become essential in reducing cyber risks. As PwC notes:

"Clean rooms, where independent parties can analyze key data and sensitive information, have become increasingly important for minimizing cyber risks."

To maintain secure and effective communication, team members should adhere to established file-sharing protocols and utilize clear communication channels. Regular check-ins, updates, and escalation procedures help ensure everyone stays on the same page. With the right combination of tools, training, and security measures, cross-department teams can focus on strategic goals without compromising sensitive information.

Using Technology for Secure and Efficient Communication

In mergers and acquisitions (M&A), technology plays a critical role in ensuring secure and streamlined communication. Choosing the right tools isn't just a nice-to-have - it's a necessity. Consider this: 62% of companies encounter cybersecurity risks during M&A, and 53% report major security incidents. On top of that, data breaches in 2023 cost an average of $4.45 million, marking a 15% increase over three years.

Beyond security, poor technology integration can lead to disastrous outcomes. Take Banco Sabadell's 2018 acquisition of TSB, for example. A failed data migration caused widespread system outages and significant financial losses. As McKinsey analysts highlighted:

"Executives from IT and operations often aren't included in the due diligence process, preventing them from offering valuable input on the costs and practical realities of integration."

The following sections dive into key strategies for leveraging technology to secure and optimize M&A communication.

Encryption and Data Protection Tools

Virtual Data Rooms (VDRs) are a go-to solution for managing sensitive documents securely. These platforms use encryption to protect files, and two-factor authentication adds an extra layer of security when external advisors or legal teams need temporary access.

Role-based access control (RBAC) is another essential tool, ensuring team members can only access data relevant to their roles. Pair this with Data Loss Prevention (DLP) strategies, which monitor for unusual activity - like large file downloads or suspicious email attachments - to prevent unauthorized data transfers.

Integrating with Existing Business Systems

Security is just one piece of the puzzle - smooth integration is equally important. Cloud-based integration platforms (iPaaS) allow companies to connect different systems without disrupting daily operations. For instance, when Company M acquired a tech startup, they used an iPaaS solution to integrate their sales, marketing, and customer service platforms. The result? Enhanced efficiency and security.

In another case, Company Z faced data inconsistencies after acquiring a smaller firm. By implementing a data integration platform and conducting thorough data cleansing, they created a unified customer database. This not only improved sales forecasting but also enabled more targeted marketing efforts. Cloud-based platforms simplify scaling by automating data exchange and coordinating workflows, making them invaluable during M&A.

Automated Record Keeping for Legal Compliance

Automation takes the burden out of maintaining compliance. Contract Lifecycle Management (CLM) software, for example, centralizes agreements and creates audit trails to meet legal requirements.

Automated systems also track every communication touchpoint - from emails to document edits - providing a detailed transaction history. These records are critical for regulatory reviews or resolving disputes post-merger. A robust audit trail should go beyond basic logs, capturing document edits, changes to permissions, and system configurations. Clear policies for system usage further ensure consistent and tamper-proof record keeping across all platforms.

Managing Company Culture Differences Through Open Communication

When it comes to mergers and acquisitions (M&A), cultural differences can be the deciding factor between success and failure. The statistics are striking: 95% of executives consider cultural fit critical to integration success, yet a lack of cultural cohesion is cited as the primary reason for failure in 25% of cases.

Successfully managing these differences is essential to achieving synergy targets. In fact, companies that address culture as part of their integration planning are 50% more likely to meet or exceed their goals. The secret? Open and honest communication that tackles cultural challenges directly, rather than ignoring them in the hope they’ll resolve on their own.

"Culture is to humans collectively what personality is to an individual." - Hofstede

This insight highlights why merging two organizations requires the same care as introducing two very different people who must work closely together. Building on this understanding allows for deliberate actions to measure, align, and adapt leadership and communication strategies across the business.

Measuring Employee Concerns and Feedback

The first step in addressing cultural differences is identifying them. Following an M&A deal, nearly 70% of employees and 74% of leaders report significant stress and uncertainty. Without proper tools to measure these concerns, they can fester and escalate into larger challenges.

A thorough culture assessment should include three elements: organization-wide surveys, focus groups across departments, and interviews with key leaders. This approach helps uncover how well the merging organizations align culturally and pinpoints potential areas of conflict.

Beverly Goulet, former executive vice president and chief integration officer at American Airlines, reflected on the importance of this step:

"One thing I wish we had done was [to create] a culture diagnostic right at the start of our planning process. That would have eliminated some of the misperceptions about both company cultures. It would have established an objective set of criteria around which we could have had conversations based on facts rather than anecdotes or beliefs."

Regular surveys are vital to track cultural integration over time, focusing on key areas like decision-making and risk-taking - aspects where alignment is often critical. A feedback loop ensures that issues identified in these surveys are addressed promptly.

For example, one assessment revealed that employees from an acquired company consistently showed lower engagement compared to legacy staff, which hindered integration efforts. This finding underscored the importance of ongoing measurement rather than relying on a one-time evaluation.

Aligning Leadership Teams

Leadership sets the tone for cultural integration. A KPMG study found that 91% of M&A deals with strong leadership alignment met or exceeded their financial targets. When leaders from both organizations present a unified front, it reassures employees and provides clarity about the merger’s direction.

Achieving this alignment requires leaders to reflect on how they’ve traditionally operated and whether those methods are suitable for the new organization. Beverly Goulet emphasized this point:

"To really get at the essence of the challenge, the leadership team needs to understand how they have worked traditionally and to consider whether that's the right way to work going forward. It has to be an introspective process that says, 'What have we done well? What might we do better? And, frankly, does the culture we want to drive going forward even match the culture we've brought into this?'"

Sometimes, this process leads to transformative changes. Bill Kozy, former executive vice president and COO at Becton, Dickinson and Company, shared his experience:

"To the credit of our CEO and senior-management team, they decided, as this process started, that 'NewCo' needed a new purpose. Of course, everybody on the buyer's side said, 'You can't change the purpose of a 117-year-old company.' But our CEO and our board said, 'Yes, we can, and it's in the best interest of the new company to do so!' They changed the purpose, and they recrafted the values to fit together nicely with this. This was thoughtfully done by our senior-management team. And the organization, particularly on the buyer's side, was really taken by this. You could hear people saying, 'This really is going to be a new place.'"

To ensure consistency, leadership workshops and regular alignment meetings are essential. These sessions should involve leaders at all levels from both organizations, working together to build a shared vision and an actionable integration plan. The goal is to go beyond surface-level agreement and achieve true alignment on values, strategic goals, and management styles.

Accommodating Different Languages

Language differences can become major hurdles during M&A integration, particularly in global deals. When employees struggle to understand communications about the merger, their anxiety and uncertainty can skyrocket. Transparent, multilingual communication can help ease these concerns.

However, effective multilingual communication isn’t just about translating words - it’s about adapting messages to resonate with different audiences. Cultures vary in how they process information, so what works for one group might not connect with another. The communication strategy should respect these differences while delivering consistent core messages.

Early opportunities for cross-organizational collaboration can also help bridge language and cultural divides. These interactions give employees from different backgrounds a chance to share experiences and build mutual understanding.

Flexibility is key. Some teams may need extra time and support to overcome language barriers, while others might adapt more quickly. One expert highlights the importance of tailoring the integration process to the level of cultural difference.

Mid-level managers play a pivotal role here. They need clear guidance on their decision-making authority and responsibilities during the integration. When equipped with the right tools and training, these managers can act as connectors, helping to facilitate smoother communication and cultural alignment across the organization.

Ultimately, investing in multilingual communication pays off. Companies that communicate effectively during M&A are 3.5 times more likely to retain employees. This makes language accommodation not just a courtesy, but a critical factor in retaining talent and maintaining engagement during the integration process.

Maintaining Communication After the Merger

Once the initial integration efforts are underway, keeping the lines of communication open becomes essential. This phase is where progress is reinforced, operations stabilize, and the merger’s long-term success is shaped. Research highlights that in the past two years, 30% of major acquisitions faced delays due to communication breakdowns, which can erode value, stall momentum, and hurt morale.

The challenges of the post-merger period are real. According to Gallup, global employee engagement dropped from 23% to 21% in 2024. Without consistent communication, even the early wins from integration can quickly unravel.

Monitoring Progress and Key Milestones

Tracking progress post-merger isn’t just about occasional updates. It requires a structured system to assess whether schedules, budgets, and targets are on track. Regular updates not only celebrate achievements but also help keep stakeholders aligned.

These updates should be tailored to the needs of different groups. For instance, IT teams may focus on system integrations, while sales teams prioritize customer retention. A one-size-fits-all approach won’t work here.

Equally important is establishing two-way communication. Tools like pulse surveys, integration barometers, town halls, focus groups, and feedback channels via email or websites can help ensure that messages are understood and gaps are quickly addressed.

Here’s how feedback methods can be customized for different stakeholders:

Stakeholder Group	Feedback Gathering Methods
Employees	Pulse surveys, Q&A sessions, One-on-one meetings
Customers	Feedback forms, Dedicated support lines, Customer surveys
Suppliers and Partners	Workshops, Account manager check-ins, Regular meetings
Media and Public	Media monitoring, Briefings

Leaders also need to be realistic about how much valid feedback they can gather. Collecting accurate data requires honesty about the organization’s capabilities.

Iliana Garcia, employer brand and strategy director at Renuity Home, underscores the importance of transparency during this phase:

"The most important thing managers can do during the process is address employee concerns with the best clarity they can provide".

This clarity becomes especially critical as the initial excitement of the merger gives way to the everyday challenges of integration.

Recording Knowledge Transfer Processes

Knowledge transfer is one of the most vital aspects of post-merger communication. When done poorly, it can lead to productivity losses, employee dissatisfaction, increased costs, and even reputational harm. The challenge lies in transferring not just explicit information but also tacit knowledge - the expertise and insights that live in employees’ heads.

A systematic approach is key. Leadership should form a steering committee to oversee the transfer process. This group can conduct a knowledge audit to identify what needs to be shared, eliminate outdated information, and address any gaps.

For example, Royal Dutch Shell Corporation’s Retention of Critical Knowledge (ROCK) methodology is designed specifically to capture tacit knowledge. Methods like training sessions, mentorship programs, and informational interviews - especially when recorded for future use - can help make this knowledge accessible.

Another critical step is creating a centralized repository for all essential information. This prevents knowledge from being scattered across different systems and ensures that everyone has access to the same resources.

As Ikujiro Nonaka, a renowned scholar, once said:

"In an economy where the only certainty is uncertainty, the one sure source of lasting competitive advantage is knowledge".

This insight is particularly relevant during mergers, where preserving and sharing knowledge can define the organization’s future success.

Creating Long-Term Accountability Systems

To ensure communication improvements last, accountability systems need to be in place. A well-crafted communication plan aligns employees, suppliers, and stakeholders with the merger’s goals, reducing uncertainty and minimizing disruptions. However, this plan shouldn’t remain static - it must evolve as the organization transitions into steady-state operations.

Consistent messaging is a cornerstone of long-term success. Sherry Duda of Korn Ferry emphasizes this point:

"CEOs often mention how exhausted they feel saying the same thing over and over again, but that this messaging consistency is also critical for keeping people engaged and focused".

Regular updates are especially important during the post-merger phase when attention starts shifting to other priorities. A strong accountability framework ensures that top leaders and middle managers stay informed weekly. Middle managers play a crucial role in translating high-level strategies into actionable steps, so they need clear guidance on decision-making and regular progress updates.

Feedback collection should remain a priority, with leaders acting on it to demonstrate that employees’ voices are heard. Aligning leadership, middle managers, and customer-facing teams ensures that communication remains effective and cohesive.

Brittany LaBovick, vice president of employee experience at Renuity Home, highlights the importance of maintaining morale:

"It can be a tough process to navigate sometimes - I think bringing a little levity or humor to the table with your reports as a manager can really improve morale".

This human touch becomes even more important as the formal integration phase winds down.

A strategic communication plan doesn’t just guide the early days of integration - it’s a long-term tool. Regular reviews and updates keep the plan relevant as the merged organization evolves.

The numbers back this up. A 2024 study by WTW found that 72% of companies implement retention strategies to address employee concerns during M&A transitions. In the healthcare sector, nearly 50% of employees reconsider their roles after a merger, and only 20% feel fully supported during the process. These statistics highlight the importance of robust communication and accountability systems in navigating the complexities of post-merger integration.

Conclusion: Key Points for Effective Team Communication in M&A

Strong team communication is the backbone of successful mergers and acquisitions. Companies that emphasize clear and effective communication during these transitions are far more likely to see positive outcomes. In fact, a 2019 Deloitte study found that organizations with solid communication strategies are 3.5 times more likely to retain employees during M&A events.

Start Early and Strategically
Planning communication efforts well before any public announcements is crucial. Early preparation helps map out key stakeholders, align messaging, and ensure compliance with legal requirements from the outset. This approach is especially important given that 73% of employees view M&A communication as critical in reducing anxiety and uncertainty during the process. Establishing this clarity early on sets the stage for leveraging the right technological tools to keep communication secure and efficient.

The Role of Technology in Communication
Technology plays a pivotal role in ensuring smooth collaboration. A 2024 Gartner survey revealed that 56% of employees feel unprepared for M&A changes due to inefficient processes. Tools that offer encryption, data protection, and automated record-keeping not only safeguard sensitive information but also simplify the overall communication workflow.

Addressing Cultural Challenges
Cultural alignment is another key factor. Mismanaged cultural differences account for roughly 30% of failed mergers and acquisitions. However, organizations that actively address cultural integration are about 50% more likely to surpass their synergy goals. Focusing on culture alongside operational goals can significantly improve the likelihood of success.

Post-Merger Communication and Trust
Communication doesn’t end with the announcement or initial integration - it’s an ongoing process. Honest, transparent messaging fosters trust, even when the news isn’t what employees want to hear. As Joanna Hall from Afire Consulting states:

"Employees will trust and respect leadership more if the comms are honest, even if they don't like the message".

Maintaining consistent updates, monitoring progress, and ensuring effective knowledge transfer are essential to sustaining the integration process. These efforts build accountability and reinforce the groundwork laid during the early stages.

The stakes in M&A are undeniably high. McKinsey reports that only 38% of deals meet their objectives when change management is neglected. However, with thoughtful communication strategies, organizations can navigate the complexities of mergers and acquisitions and emerge stronger.

For businesses looking to streamline their M&A communication efforts, platforms like Kumo offer a practical starting point, equipping teams with the tools needed to execute comprehensive and effective strategies for successful integrations.

FAQs

What are the best ways to communicate effectively with stakeholders during an M&A process?
