Mergers and Acquisitions Examples: The largest company M&A deals list

Kison Patel is the Founder and CEO of DealRoom, a Chicago-based diligence management software that uses Agile principles to innovate and modernize the finance industry. As a former M&A advisor with over a decade of experience, Kison developed DealRoom after seeing first hand a number of deep-seated, industry-wide structural issues and inefficiencies.

When it comes to mergers and acquisitions, bigger doesn’t always mean better - the examples we included in our list of the biggest M&A failures is evidence of that.

In fact, all things being equal, the bigger a deal becomes, the bigger the likelihood that the buyer is overpaying for the target company. But whether you like mega deals or not, we cannot afford to ignore them. 

At DealRoom , we help companies evolve and streamline multiple large and successful M&A deals each year. In this article, we collected some of the biggest deals in history.

Biggest mergers and acquisitions examples list.

Reading this list, it can seem that the biggest deals are doomed to failure (at least from the perspective of their shareholders). But thankfully, that just isn’t the case. Some of the biggest M&A transactions of the past 30 years have been outstanding successes.

Many of these deals have achieved what they set out to do at the outset - to reshape industries on the strength of a single deal.

With that in mind, let's take a closer look at 25 companies that recorded the largest mergers and acquisitions in history.

1. Vodafone and Mannesmann (1999) - $202.8B ($373B adjusted for inflation)

As of March 2024, the takeover of Mannesmann by Vodafone in 2000 was still one of the largest acquisitions ever made. Worth ~ $203 billion at that time, Vodafone, a mobile operator based in the United Kingdom, acquired Mannesmann, a German-owned industrial conglomerate company.

This deal made Vodafone the world’s largest mobile operator and set the scene for dozens of mega deals in the mobile telecommunications space in the years that followed. This deal is still considered as the biggest acquisition in history.

2. Shenhua Group and China Guodian Corporation (2017) - $278B ($354B adjusted for inflation)

The merger between Shenhua Group and China Guodian Corporation is the biggest example of a merger of equals that happened in 2017. Shenhua Group is China’s largest coal provider, while China Guodian Corporation is one of the top five electricity producers.

This $278 billion merger created the world’s largest power utility company by installed capacity. The goal of the merger was to create a balanced energy portfolio between coal power and renewable energy. This is to align with China’s broader environmental and economic objectives .

3. AOL and Time Warner (2000) - $182B ($325B adjusted for inflation)

When we mentioned at the outset of this article that ‘ big doesn’t always mean better ’, the famous merger of AOL, a U.S.-based internet service provider, and Time Warner, an American cable television company, in 2000 is a case in point. 

In little over two decades, the deal has become cemented as the textbook example of how not to conduct mergers and acquisitions. It featured everything from overpaying to strong cultural differences and even, with the benefit of hindsight, two large media companies who just weren’t sure where the media landscape was headed. 

The merger's valuation came crashing down after the dot-com bubble burst just two months after the deal was signed. The deal, which is to be known as the largest merger in history, fell apart in 2009, 9 years later after it was originally signed.

4. ChemChina and Sinochem (2018) - $245B ($309B adjusted for inflation)

The ChemChina and Sinochem merger was part of the Chinese government’s bigger plan to strengthen their competitiveness in the global stage by reducing the overall number of its state-owned enterprises through merging its biggest companies to create a larger firm.

This specific merger created the world’s largest industrial chemicals company, known as Sinochem Holdings, which surpassed major global competitors like BASF in North America in terms of scale and market presence.

5. Gaz de France and Suez (2007) - $182B ($259B adjusted for inflation)

France loves its national champions - the large French companies that compete on a world stage, waving the tricolor. It was no surprise then, when Nicholas Sarkozy, President of France in 2007, stepped in to save this merger.

That’s right - a President playing the role of part-time investment banker. These days, Suez is one of the oil and gas ‘majors’, although the fact that the company’s share price hovers very close to where it was a decade and a half ago tells us everything of what investors thought of the deal.

The deal, one of the biggest mergers ever in energy, created the world’s fourth largest energy company and Europe’s second largest electricity and gas group. The merged companies created a diversified, flexible energy supply stream with a high-performance electricity production base.

6. Glaxo Wellcome and SmithKline Beecham merger (2000) - $107B  ($197B adjusted for inflation)

The merger of the UK’s two largest pharmaceutical firms in 2000 led to what is currently the 6th largest pharmaceutical firm in the world, and the only British firm in the top 10.

However, like several deals on this list, it wasn’t received particularly well by investors and at the time of writing is trading at about 25% less than the time of the merger.

This, and a range of bolt-on acquisitions in the consumer space over the past decade, may explain why the company is planning to split into two separate companies in the coming years.

7. Verizon and Vodafone (2013) - $130B ($173B adjusted for inflation)

Vodafone has been involved in so many transactions over the past 20 years that they should be getting quite efficient at the process at this stage. The $130B deal in 2013 allowed Verizon to pay for its US wireless division.

At the time, the deal was the third largest in history - two of which Vodafone had partaken in. From Verizon’s perspective, it gave the company full control over its wireless division, ending an often fraught relationship with Vodafone that lasted for over a decade, and also allowed it to build new mobile networks and contend with an increasingly competitive landscape at the time.

From Vodafone's point of view, the acquisition cut the company value roughly in half, to $100 billion. The business acquisition also moved Vodafone from the second largest phone company in the world down to fourth, behind China Mobile, AT&T, and Verizon.

8. Dow Chemical and DuPont merger (2015) - $130B ($166B adjusted for inflation)

When Dow Chemical and DuPont announced they were merging in 2015, everyone sat up and took notice; the merger of equals would create the largest chemicals company by sales in the world, as well as eliminate the competition between them, making it a picture-perfect example of horizontal merger.

Shortly after the deal was completed, in 2018, the company was already generating revenue of $86B a year - but it didn’t last long: In 2019, management announced that the merged company would spin off into three separate companies, each with a separate focus.

9. United Technologies and Raytheon (2019) - $121B ($147B adjusted for inflation)

The merger between United Technologies Corporation (UTC) and Raytheon Company created Raytheon Technologies, an aerospace and defense giant. The new legal entity is expected to be the leader in aerospace and defense industries, with a broadened portfolio and enhanced market reach.

Now that the deal went through, Raytheon can leverage United Technologies' expertise in high temperature materials for jet engines; and in directed energy weapons, United Technologies has relevant power generation and management technology.

So far, however, investors seem less convinced with the company’s share price taking a dip of around 25% straight after the deal closed.

10. AB InBev and SABMiller merger (2015) - $107B  ($138B adjusted for inflation)

If stock price is any indication of whether a deal was successful or not, then the creation of AmBev through the merger of InBev and SABMiller in 2015 certainly wasn’t.

On paper, the deal looked good - two of the world’s biggest brewers bringing a host of the world’s favorite beers into one stable.

There was just one problem - they didn’t foresee the rise of craft beers and how it would disrupt the brewing industry. Several bolt-on acquisitions of craft brewers later and the new company may finally be on track again.

11. AT&T and Time Warner (2018) - $108B ($134B adjusted for inflation)

Not only did the proposed merger of AT&T and Time Warner draw criticism from antitrust regulators when it was announced, it also brought back memories of the previous time Time Warner had been involved in a megadeal.

With the best part of two decades to learn from its mistake, and AT&T a much bigger cash generator than AOL, this deal looks like it has been better thought through than the deal that preceded it.

12. Heinz and Kraft merger (2015) - $100B  ($131B adjusted for inflation)

The merger of Heinz and Kraft - to create the Kraft Heinz Company - is yet another megadeal that has a detrimental effect on stock.

The deal has been called a “ mega-mess ,” with billions knocked off the stock price since the deal closed. One of the reasons has been allegations made about accounting practices at the two firms before the merger.

Another reason has been zero-based budgeting (ZBB), a strict cost cutting regime that came at a time when old brands needed to be refreshed rather than have their budgets cut back.

13. BMO Financial Group and Bank of the West (2021) - $105B ($119.5B adjusted for inflation)

On December 20, 2021, BMO Financial Group announced the acquisition of BNP Paribas SA unit Bank of the West and its subsidiaries with assets worth approximately $105B. This merger is expected to significantly expand BMO’s presence in the U.S.

Through this acquisition, BMO can expand their customer base, increase their market presence in new regions, and enhance their existing capabilities with complementary products and services offered by Bank of the West.

14. Bristol-Myers Squibb and Celgene merger (2019) - $95B  ($115B adjusted for inflation)

Despite the massive size of the transaction, this 2019 megadeal wasn’t a “merger of equals.” Instead, Celgene became a subsidiary of Bristol-Myers Squibb. The deal brings together two of the world’s largest cancer drug manufacturers, so hopefully the deal amounts to something much greater than the sum of the parts.

15. Energy Transfer Equity and Energy Transfer Partners (2018) - $90B  ($111B adjusted for inflation)

This deal is part of a strategic initiative to simplify Energy Transfer Equity’s corporate structure and streamlining their operations.​

Each ETP unit was converted into 1.28 ETE units, resulting in a major redistribution of shares but keeping the business essentially continuous under a new name. 

ETE was renamed Energy Transfer LP and began trading under the ticker symbol "ET" on the New York Stock Exchange. On the other hand, ETP was renamed Energy Transfer Operating L.P.

16. Unilever plc and Unilever N.V. (2020) - $81B  ($97B adjusted for inflation)

The M&A deal between Unilever plc and Unilever N.V. in 2020 was essentially a unification strategy. The primary goal was to create a more cohesive organization with streamlined operations and increased strategic flexibility. 

During this process, they made sure nothing will change in their operations, locations, activities or staffing levels in either The Netherlands or the United Kingdom.

17. Walt Disney and 21st Century Fox (2017) - $52.4B ($83.7B adjusted for inflation)

In December 2017, The Walt Disney Company acquired 21st Century Fox. Walt Disney’s goal was to boost their global presence and content diversity, adding to its strong franchise and streaming service portfolio. This acquisition enhanced Disney’s entertainment library and direct-to-consumer streaming offerings, bringing franchises like X-Men and Deadpool under one roof.

18. Bayer and Monsanto (2018) - $63B ($78B adjusted for inflation)

The deal between Bayer and Monsanto worth approximately $63B created one of the world's biggest agrochemical and agricultural biotechnology corporations. Bayer was known widely for its pharmaceutical division, but it also has a substantial crop science division, where they offer chemical and crop protection. 

Through the Monsanto acquisition, Bayer has strengthened their agricultural business using Monsanto’s expertise, which ultimately made them a global leader in seeds, traits, and agricultural chemicals.

After the completion of the deal in 2018, the integration has been complex due to the legacy issues inherited from the acquisition of Monsanto, such as culture, reputation, and legal and regulatory issues.

19. Microsoft and Activision Blizzard (2023) - $75.4B ($76.5B adjusted for inflation)

On January 18, 2022, Microsoft announced its intent to acquire Activision Blizzard, initially valued at $68.7B. The goal of this strategic acquisition was to significantly boost its gaming segment across various platforms including mobile, PC, console, and cloud. 

Microsoft can do this by integrating Activision Blizzard's strong portfolio of popular gaming franchises like Call of Duty, World of Warcraft, and Candy Crush. After overcoming numerous regulatory challenges, the deal was finalized on October 13, 2023. 

This acquisition, with the total cost amounting to $75.4 billion, represents one of the largest deals in the video game industry.

20. Broadcom and VMWare (2023) - $61B ($62B adjusted for inflation)

In November 2023, Broadcom acquired VMWare to strengthen its infrastructure software business by integrating VMWare’s extensive multi-cloud services capabilities. 

Due to the large scale of both companies’ operations, the deal had to go through a massive regulatory scrutiny and review. It involved multiple jurisdictions across the globe to assess its impact on competition and market dynamics within the tech industry.

21. Exxon Mobil and Pioneer Natural Resources (2023) - $59.5B ($60B adjusted for inflation)

As part of their strategy to enhance their production capabilities and market presence in the oil and gas industry, Exxon Mobil merged with Pioneer Natural Resources. 

They announced this deal in October 2023, with the goal to achieve a partnership that would combine their strengths in terms of resources and strengthen their portfolio in the global energy market. 

ExxonMobil’s Senior Vice President, Niel Chapman, reaffirms that the deal is still on track and is set to close in the second quarter of 2024.

22. S&P Global and IHS Markit (2020) - $44B ($52.8B adjusted for inflation)

S&P Global announced an all-stock merger with IHS Markit worth $44 billion in November 2020. Through this deal, S&P Global will gain access to a data provider that supplies financial information to 50,000 customers across business and governments. Both companies expected a generated annual free cash flow of exceeding $5bn by 2023.

23. Discovery, Inc. and WarnerMedia (2022) - $43B ($46B adjusted for inflation)

On April 8, 2022, Discovery Inc. and WarnerMedia finalized a merger that would enhance their global media and entertainment footprint. The goal was to combine Warnermedia’s extensive entertainment assets with Discovery's non-fiction and international entertainment.

This $43B deal formed a new entity called Warner Bros. Discovery, which now has a vast portfolio that includes networks such as CNN, HBO, and Discovery Channel, as well as streaming services like HBO Max and Discovery+.

This horizontal merger boosted the newly formed company to compete with other major players like Netflix and Disney+ by providing a richer diversity of content across genres.

24. Pfizer and Seagen (2023) - $43B ($43.7B adjusted for inflation)

Pfizer’s acquisition of Seagen for $43B in March 2023 marked one of the largest deals in the biopharmaceutical sector since 2019.

Since Seagen is a biotech company known for its expertise in developing antibody-drug conjugates (ADCs) and other innovative cancer therapies, this acquisition will strengthen Pfizer’s oncology portfolio and expand their presence in the cancer treatment market.

25. Altimeter and Grab Holdings (2021) - $40B ($46.7B adjusted for inflation)

Altimeter’s stock-for-stock merger with Grab Holdings marked as the largest de-SPAC transaction at that time, worth approximately $40B. 

Instead of a traditional IPO process, Altimeter helped Grab go public through a reverse merger. The primary motive of the deal was to boost Grab's dominance in Southeast Asia by providing them with additional capital to propel their expansion and face their fierce competition, particularly Gojek.

It's a win-win move for Altimeter because the merger carved an opportunity for them to invest in a fast-growing tech company with a solid market presence in a rapidly developing region.

Merger examples

A merger is a transaction of two companies, usually of similar size, mutually agreeing to combine their businesses into one entity. 

This is distinct from an acquisition , where one company (the buyer) buys the outstanding shares of a target company, and the target company’s shareholders receive the proceeds from selling those shares.

Here are a few examples of mergers that have happened in the M&A landscape:

Exxon Mobil and Pioneer Natural Resources (2023) - $59.5B ($60B adjusted for inflation)

This is a great example of a merger of equals where no payment was made from one company to another. This was an all-stock transaction, where Pioneer shareholders will receive 2.3234 shares of ExxonMobil for each Pioneer share at closing.

United Technologies and Raytheon (2019) - $121B ($147B adjusted for inflation)

Another classic example of a so-called “ merger of equals .” The United Technologies and Raytheon merger is also an all-stock transaction, where Raytheon shareholders receive shares in the new company, while UTC shareholders maintain a majority stake.

Discovery, Inc. and WarnerMedia (2022) - $43B ($46B adjusted for inflation)

Despite the first two examples mentioned above, not all mergers involve two equal-sized companies. When AT&T owned WarnerMedia, they merged it with a smaller company, Discovery Inc. This special kind of deal is called a Reverse Morris Trust. So even though it's a merger, AT&T got $40.4 billion in cash as a payment. 

This payment was part of the deal to help balance things out between what AT&T was giving up and what they were getting in return. AT&T shareholders also ended up owning a big part of the combined company.

Acquisition example

An acquisition is a transaction whereby companies, organizations, and/or their assets are acquired for some consideration by another company. The motive for one company to acquire another is nearly always growth. 

In the next section, let’s take a look at great acquisitions examples that have happened in M&A history.

Microsoft and Activision Blizzard (2022) - $75.4B ($76.5B adjusted for inflation)

This is an example of an outright acquisition. In December 2021, Blizzard faced allegations and a lawsuit regarding workplace misconduct, specifically discrimination against women employees. Their reputation and business operations were taking a hit, and they wanted an out. 

Meanwhile Microsoft wanted Activision's iconic franchises like “Call of Duty” and “World of Warcraft” to increase their presence in the gaming industry. Activision saw Microsoft’s acquisition as a way to address internal issues under new leadership, while Microsoft potentially expanding its footprint in the gaming industry.

Walt Disney and 21st Century Fox (2017) - $52.4B ($83.7B adjusted for inflation)

Another classic example of an acquisition is the Walt Disney and 21st Century Fox deal. During this time, the media landscape was rapidly changing and traditional media companies like 21st Century Fox were facing significant competition from new digital entrants like Netflix and Amazon. Fox wanted to sell their company to focus on their core strengths, primarily news and sports. 

On the other hand, Walt Disney had better content creation and distribution, which allowed them to benefit from this transaction.

Amazon and Whole Foods (2017) - $13.7B ($17B adjusted for inflation)

Though this deal did not make our top 25, it’s certainly a great example of a successful acquisition. Amazon bought Whole Foods in 2017 for approximately $13.7B to have greater control of their supply chain and broaden their reach into new markets. 

Before this deal, Amazon was more focused on e-commerce. This strategic move allowed them to expand into the brick-and-mortar grocery sector, through Whole Foods. Amazon was able to integrate its e-commerce capabilities with Whole Foods' physical store network and achieved economies of scale in several areas, especially in distribution and logistics.

Lessons from successful and failed mergers and acquisitions 

Whether it’s a success or failure, there are always lessons to be learned in the world of mergers & acquisitions. Here are some of the best lessons we want to emphasize and share.

Don’t overlook culture 

In the past, culture was one of the most underrated aspects of M&A. No one cared about it, and deal makers were only focused on the numbers and synergies. Today, practitioners are catching on, and they tend to focus more on culture during due diligence. But for those who are still not believers, you can always look up the Daimler Benz and Chrysler deal back on May 7, 1998. 

Daimler was aggressive during integration and Chrysler didn’t want to be told what to do. They didn’t get along and continued to run as separate operations. The entire deal was a disaster, which eventually led to Daimler Benz selling Chrysler to the Cerberus Capital Management firm.

Don’t take due diligence for granted

M&A teams must never take due diligence for granted and turn every possible stone. One mistake can cause massive headaches, and potentially destroy the acquiring company.  HP learned this the hard way when they acquired Autonomy back in 2011. The plan was to transform HP from a computer and printer maker into a software-focused enterprise services firm. 

The problem came after the deal was closed, and HP discovered that Autonomy was cooking the books by selling hardware at a loss to its customers while booking the sales as software licensing revenue. This is one of the most controversial deals of all time, generating massive lawsuits due to fraudulent accounting practices.

Plan for integration early in the process

The biggest mistake any practitioner could make is not planning for integration early in the M&A process . Integration is where value is created, and must be prioritized during due diligence. 

The Sprint and Nextel Communications deal back in 2005 is a great example of the importance of integration planning. The combination of these two legal entities created the third largest telecommunications provider at that time. The goal is to gain access to each other's customer bases and cross sell their product lines. 

However due to the lack of integration planning during the diligence they were not prepared for what was about to come after closing. Apparently the two companies' networks did not share the same technology and had zero overlap making integration extremely difficult. They also lost a significant amount of market share due to their clashing marketing strategies that allowed rivals to steal dissatisfied customers.

Final thoughts

Overall, it’s hard to argue which deal in US history is the most successful merger or acquisition due to the fact that sometimes the full value and potential of a deal takes years to formulate.

However, the top mergers and acquisitions take into account best practices such as robust communication, focus on the strategic goal/deal thesis, and early integration planning throughout the deal lifecycle.

Much can be learned from companies that have successfully merged with or acquired other companies.

Hacking the Case Interview

Merger & acquisition (M&A) cases are a common type of case you’ll see in consulting interviews. You are likely to see at least one M&A case in your upcoming interviews, especially at consulting firms that have a large M&A or private equity practice.

These cases are fairly straight forward and predictable, so once you’ve done a few cases, you’ll be able to solve any M&A case.

In this article, we’ll cover:

• Two types of merger & acquisition case interviews
• The five steps to solve any M&A case
• The perfect M&A case interview framework
• Merger & acquisition case interview examples
• Recommended M&A case interview resources

Two Types of Merger & Acquisition Case Interviews

A merger is a business transaction that unites two companies into a new and single entity. Typically, the two companies merging are roughly the same size. After the merger, the two companies are no longer separately owned and operated. They are owned by a single entity.

An acquisition is a business transaction in which one company purchases full control of another company. Following the acquisition, the company being purchased will dissolve and cease to exist. The new owner of the company will absorb all of the acquired company’s assets and liabilities.

There are two types of M&A cases you’ll see in consulting case interviews:  

A company acquiring or merging with another company

• A private equity firm acquiring a company, also called a private equity case interview

The first type of M&A case is the most common. A company is deciding whether to acquire or merge with another company.

Example: Walmart is a large retail corporation that operates a chain of supermarkets, department stores, and grocery stores. They are considering acquiring a company that provides an online platform for small businesses to sell their products. Should they make this acquisition?

There are many reasons why a company would want to acquire or merge with another company. In making an acquisition or merger, a company may be trying to:

• Gain access to the other company’s customers
• Gain access to the other company’s distribution channels
• Acquire intellectual property, proprietary technology, or other assets
• Realize cost synergies
• Acquire talent
• Remove a competitor from the market
• Diversify sources of revenue

A private equity firm acquiring a company

The second type of M&A case is a private equity firm deciding whether to acquire a company. This type of M&A case is slightly different from the first type because private equity firms don’t operate like traditional businesses.

Private equity firms are investment management companies that use investor money to acquire companies in the hopes of generating a high return on investment.

After acquiring a company, a private equity firm will try to improve the company’s operations and drive growth. After a number of years, the firm will look to sell the acquired company for a higher price than what it was originally purchased for.

Example: A private equity firm is considering acquiring a national chain of tattoo parlors. Should they make this investment?

There are a few different reasons why a private equity firm would acquire a company. By investing in a company, the private equity firm may be trying to:

• Generate a high return on investment
• Diversify its portfolio of companies to reduce risk
• Realize synergies with other companies that the firm owns

Regardless of which type of M&A case you get, they both can be solved using the same five step approach.

The Five Steps to Solve Any M&A Case Interview

Step One: Understand the reason for the acquisition

The first step to solve any M&A case is to understand the primary reason behind making the acquisition. The three most common reasons are:

• The company wants to generate a high return on investment
• The company wants to acquire intellectual property, proprietary technology, or other assets
• The company wants to realize revenue or cost synergies

Knowing the reason for the acquisition is necessary to have the context to properly assess whether the acquisition should be made.

Step Two: Quantify the specific goal or target

When you understand the reason for the acquisition, identify what the specific goal or target is. Try to use numbers to quantify the metric for success.

For example, if the company wants a high return on investment, what ROI are they targeting? If the company wants to realize revenue synergies, how much of a revenue increase are they expecting?

Depending on the case, some goals or targets may not be quantifiable. For example, if the company is looking to diversify its revenue sources, this is not easily quantifiable.

Step Three: Create a M&A framework and work through the case

With the specific goal or target in mind, structure a framework to help guide you through the case. Your framework should include all of the important areas or questions you need to explore in order to determine whether the company should make the acquisition.

We’ll cover the perfect M&A framework in the next section of the article, but to summarize, there are four major areas in your framework:

Market attractiveness : Is the market that the acquisition target plays in attractive?

Company attractiveness : Is the acquisition target an attractive company?

Synergies : Are there significant revenue and cost synergies that can be realized?

Financial implications : What are the expected financial gains or return on investment from this acquisition?

Step Four: Consider risks OR consider alternative acquisition targets

Your M&A case framework will help you investigate the right things to develop a hypothesis for whether or not the company should make the acquisition.

The next step in completing an M&A case depends on whether you are leaning towards recommending making the acquisition or recommending not making the acquisition.

If you are leaning towards recommending making the acquisition…

Explore the potential risks of the acquisition.

How will the acquisition affect existing customers? Will it be difficult to integrate the two companies? How will competitors react to this acquisition?

If there are significant risks, this may change the recommendation that you have.

If you are leaning towards NOT recommending making the acquisition…

Consider other potential acquisition targets.

Remember that there is always an opportunity cost when a company makes an acquisition. The money spent on making the acquisition could be spent on something else.

Is there another acquisition target that the company should pursue instead? Are there other projects or investments that are better to pursue? These ideas can be included as next steps in your recommendation.

Step Five: Deliver a recommendation and propose next steps

At this point, you will have explored all of the important areas and answered all of the major questions needed to solve the case. Now it is time to put together all of the work that you have done into a recommendation.

Structure your recommendation in the following way so that it is clear and concise:

• State your overall recommendation firmly
• Provide three reasons that support your recommendation
• Propose potential next steps to explore

The Perfect M&A Case Interview Framework

The perfect M&A case framework breaks down the complex question of whether or not the company should make the acquisition into smaller and more manageable questions.

You should always aspire to create a tailored framework that is specific to the case that you are solving. Do not rely on using memorized frameworks because they do not always work given the specific context provided.

For merger and acquisition cases, there are four major areas that are the most important.

1. Market attractiveness

For this area of your framework, the overall question you are trying to answer is whether the market that the acquisition target plays in is attractive. There are a number of different factors to consider when assessing the market attractiveness:  

• What is the market size?
• What is the market growth rate?
• What are average profit margins in the market?
• How available and strong are substitutes?
• How strong is supplier power?
• How strong is buyer power?
• How high are barriers to entry?

2. Company attractiveness

For this area of your framework, the overall question you want to answer is whether the acquisition target is an attractive company. To assess this, you can look at the following questions:

• Is the company profitable?
• How quickly is the company growing?
• Does the company have any competitive advantages?
• Does the company have significant differentiation from competitors?

3. Synergies

For this area of your framework, the overall question you are trying to answer is whether there are significant synergies that can be realized from the acquisition.

There are two types of synergies:

• Revenue synergies
• Cost synergies

Revenue synergies help the company increase revenues. Examples of revenue synergies include accessing new distribution channels, accessing new customer segments, cross-selling products, up-selling products, and bundling products together.

Cost synergies help the company reduce overall costs. Examples of cost synergies include consolidating redundant costs and having increased buyer power.

4. Financial implications

For this area of your framework, the main question you are trying to answer is whether the expected financial gains or return on investment justifies the acquisition price.

To do this, you may need to answer the following questions:  

• Is the acquisition price fair?
• How long will it take to break even on the acquisition price?
• What is the expected increase in annual revenue?
• What are the expected cost savings?
• What is the projected return on investment?

Merger & Acquisition Case Interview Examples

Let’s put our strategy and framework for M&A cases into practice by going through an example.

M&A case example: Your client is the second largest fast food restaurant chain in the United States, specializing in serving burgers and fries. As part of their growth strategy, they are considering acquiring Chicken Express, a fast food chain that specializes in serving chicken sandwiches. You have been hired to advise on whether this acquisition should be made.

To solve this case, we’ll go through the five steps we outlined above.

The case mentions that the acquisition is part of the client’s growth strategy. However, it is unclear what kind of growth the client is pursuing.

Are they looking to grow revenues? Are they looking to grow profits? Are they looking to grow their number of locations? We need to ask a clarifying question to the interviewer to understand the reason behind the potential acquisition.

Question: Why is our client looking to make an acquisition? Are they trying to grow revenues, profits, or something else? 

Answer: The client is looking to grow profits.

Now that we understand why the client is considering acquiring Chicken Express, we need to quantify what the specific goal or target is. Is there a particular profit number that the client is trying to reach?

We’ll need to ask the interviewer another question to identify this.

Question: Is there a specific profit figure that the client is trying to reach within a specified time period?

Answer: The client is trying to increase annual profits by at least $200M by the end of the first year following the acquisition.

With this specific goal in mind, we need to structure a framework to identify all of the important and relevant areas and questions to explore. We can use market attractiveness, company attractiveness, synergies, and financial implications as the four broad areas of our framework.

We’ll need to identify and select the most important questions to answer in each of these areas. One potential framework could look like the following:

Let’s fast forward through this case and say that you have identified the following key takeaways from exploring the various areas in your framework:

• Chicken Express has been growing at 8% per year over the past five years while the fast food industry has been growing at 3% per year
• Among fast food chains, Chicken Express has the highest customer satisfaction score
• Revenue synergies would increase annual profit by $175M. This is driven by leveraging the Chicken Express brand name to increase traffic to existing locations
• Cost synergies would decrease annual costs by $50M due to increased buyer power following the acquisition

At this point, we are leaning towards recommending that our client acquire Chicken Express. To strengthen our hypothesis, we need to explore the potential risks of the acquisition.

Can the two companies be integrated smoothly? Is there a risk of sales cannibalization between the two fast food chains? How will competitors react to this acquisition?

For this case, let’s say that we have investigated these risks and have concluded that none of them pose a significant threat to achieving the client’s goals of increasing annual profit by $200M.

We’ll now synthesize the work we have done so far and provide a clear and concise recommendation. One potential recommendation may look like the following:

I recommend that our client acquires Chicken Express. There are three reasons that support this.

One, Chicken Express is an attractive acquisition target. They are growing significantly faster than the fast food industry average and have the highest customer satisfaction scores among fast food chains.

Two, revenue synergies would increase annual profit by $175M. The client can leverage the brand name of Chicken Express to drive an increase in traffic to existing locations.

Three, cost synergies would decrease annual costs by $50M. This is due to an increase in buyer power following the acquisition.

Therefore, our client will be able to achieve its goal of increasing annual profits by at least $200M. For next steps, I’d like to assess the acquisition price to determine whether it is reasonable and fair.
