Synergies are a powerful concept in mergers and acquisitions (M&A). They represent the potential for two companies to come together to create greater value than they could achieve individually. The idea is that the combined entity is worth more than the sum of its parts, allowing for increased efficiency, scale, and financial benefits. In this comprehensive guide, we will explore the concept of synergies in M&A and examine the different types of synergies that can be realised. We will also discuss the importance of synergies in deal valuation and the challenges involved in capturing and estimating synergies. So, let’s dive in and unlock the secrets of synergies in M&A.
What are Synergies in M&A?
Synergies, in the context of M&A, refer to the combined value and performance of two companies that is greater than the sum of their individual parts. When two companies merge or one acquires the other, they aim to leverage the synergistic effect to create a stronger and more profitable business. The goal is to achieve greater efficiency, scale, and financial performance by combining resources, capabilities, and market presence.
The Importance of Synergies in M&A
Synergies are a crucial factor in M&A transactions as they directly impact the value and success of the deal. For buyers, understanding the potential synergies allows them to determine the maximum price they can afford to pay for the target company. On the other hand, sellers can leverage the potential synergies to negotiate a higher purchase price. By quantifying and valuing the synergies, both parties can make informed decisions and create a win-win situation.
Types of Synergies in M&A
There are several types of synergies that can be realised in M&A transactions. Let’s explore the three main types, with a focus on examples from recent tech deals where relevant, as these often highlight emerging opportunities in areas like artificial intelligence (AI):
- Revenue Synergies
Revenue synergies arise when the combined entity can generate more sales or revenue than the individual companies could achieve on their own. This can be achieved through various means, such as cross-selling products or services, accessing new markets or customers, or leveraging complementary strengths and capabilities. Revenue synergies are often considered the most desirable type of synergy as they directly contribute to top-line growth and increased market share.
In the tech sector, for instance, Hewlett Packard Enterprise’s (HPE) $14 billion acquisition of Juniper Networks in 2024 (finalised in 2025) aimed to double HPE’s networking business by integrating Juniper’s AI-native Mist platform, enabling new AI-driven services and expanded market penetration in edge-to-cloud solutions.crn.com Similarly, AI opportunities here include combining datasets and algorithms to develop innovative products, such as enhanced generative AI capabilities, as seen in IBM’s $6.4 billion purchase of HashiCorp in 2024, which bolstered hybrid cloud offerings for AI applications.crn.com
- Cost Synergies
Cost synergies involve reducing expenses and achieving cost savings by eliminating redundancies, streamlining operations, and optimising resources. This can include reducing staff headcount, consolidating offices and facilities, renegotiating supplier contracts, and leveraging economies of scale. Cost synergies aim to improve operational efficiency and profitability by eliminating duplicate functions and leveraging shared resources.
A notable example is Cisco’s $28 billion acquisition of Splunk in 2024, where synergies included integrating observability and security platforms to reduce operational redundancies and lower costs through unified data management.crn.com In tech M&A, AI can present opportunities for further cost savings via automation, such as using AI tools to optimise supply chains or automate routine processes post-integration.
- Financial Synergies
Financial synergies are related to the financial structure and capital management of the combined entity. By combining the financial resources and capabilities of two companies, there may be opportunities to reduce the cost of capital, access new funding sources, and optimise the capital structure. Financial synergies can result in lower borrowing costs, increased debt capacity, and improved financial performance. These may also encompass tax synergies, such as utilising net operating losses from one entity to offset taxable income in the other.
For example, in Alphabet’s $32 billion acquisition of Wiz in 2025, the deal enhanced Google’s cloud security offerings, potentially lowering overall capital costs through scaled infrastructure investments in AI and cybersecurity.cio.com
Estimating and Capturing Synergies
Estimating and capturing synergies in M&A transactions can be a complex and challenging task. It requires a comprehensive understanding of the businesses involved, their operations, and the potential for integration. Here are some key considerations:
Assessing Synergy Potential
Before embarking on an M&A transaction, it is essential to assess the potential for synergies. This involves evaluating the strategic fit between the two companies, identifying areas of overlap and complementarity, and quantifying the possible synergistic benefits. It is important to consider both the quantitative and qualitative aspects of synergies and their impact on the overall value proposition of the deal. In tech deals, this may include evaluating AI capabilities for new revenue streams or operational efficiencies.
Conducting Due Diligence
Thorough due diligence is crucial in identifying and validating potential synergies. This involves assessing the financials, operations, systems, and culture of both companies to identify areas of synergy and potential challenges. It is important to involve the right stakeholders and subject matter experts to ensure a comprehensive analysis and evaluation. AI tools are increasingly used here for faster data analysis and risk identification, presenting opportunities to streamline the process.mckinsey.com
Developing a Synergy Plan
Once the potential synergies are identified, it is vital to develop a synergy plan that outlines the specific actions and initiatives required to capture the synergistic benefits. The plan should include timelines, responsibilities, and performance metrics to track the progress and ensure accountability. A well-defined synergy plan increases the likelihood of successful integration and value creation.
Managing Integration
Integration is a critical phase in capturing synergies. It involves combining the operations, systems, processes, and people of the two companies to create a cohesive and efficient organisation. Effective integration requires strong leadership, clear communication, and a well-executed plan. It is essential to manage the cultural aspects of integration and address any potential resistance or conflicts that may arise. In AI-heavy deals, integration may involve harmonising AI models and datasets, which can unlock further value but requires careful handling of intellectual property.
Monitoring and Adjusting
Once the integration is complete, it is important to continuously monitor and assess the performance of the combined entity. This includes tracking the realisation of synergies, evaluating the financial and operational metrics, and making any necessary adjustments to optimise the outcomes. Regular monitoring and adjustment ensure that the synergistic benefits are captured and sustained over the long term.
Challenges in Estimating Synergies
Estimating synergies is not without its challenges. It requires a deep understanding of the businesses, industries, and market dynamics involved. Here are some common challenges in estimating synergies:
Overestimation or Underestimation
Estimating synergies involves making assumptions and projections about the future performance of the combined entity. There is always a risk of overestimating or underestimating the synergistic benefits. Overestimation can lead to unrealistic expectations and disappointment, while underestimation may result in missed opportunities and undervaluation of the deal.
Integration Complexity
The complexity of integrating two companies can impact the realisation of synergies. Cultural differences, incompatible systems, and operational challenges can hinder the smooth integration and delay the capture of synergistic benefits. It is important to anticipate and address these complexities during the planning and execution stages. In tech M&A involving AI, additional threats include regulatory scrutiny over data privacy, antitrust concerns in AI markets, and ethical risks related to AI biases or job displacements.aoshearman.com
Time Lag
Synergies may take time to materialise. Revenue synergies, in particular, may require changes in customer behaviour, market dynamics, or sales strategies, which can take time to implement and yield results. It is essential to have realistic timelines and expectations when estimating synergies.
External Factors
External factors, such as regulatory changes, competitive pressures, or economic conditions, can impact the realisation of synergies. It is important to consider these external factors and their potential influence on the synergistic benefits. Flexibility and adaptability are key in navigating external challenges and maximising the value of synergies. For AI-related synergies, threats like evolving AI regulations (e.g., in the EU or US) could delay or alter expected benefits.aoshearman.com
Conclusion
Synergies are a powerful driver of value in M&A transactions. They represent the potential for two companies to create greater value together than they could achieve individually. By leveraging revenue synergies, cost synergies, and financial synergies, companies can unlock new growth opportunities, improve operational efficiency, and enhance financial performance. In the tech sector, AI presents significant opportunities for enhanced synergies, such as through advanced data analytics and automation, but also introduces threats like integration risks and regulatory hurdles. Estimating and capturing synergies require careful analysis, planning, and execution. It is important to assess the potential for synergies, conduct thorough due diligence, develop a synergy plan, manage integration effectively, and continuously monitor and adjust. While estimating synergies may present challenges, a strategic and thoughtful approach can unlock the full potential of synergies in M&A transactions.
