What is the best M&A Case Study Framework?

I am prepping for a case study interview next week, and looking specifically at M&A examples and wanted to know the best framework / issue tree for approaching these types of questions. Some say that you should: (1) analyse Company A; (2) analyse Company B; and (3) analyse Company A+B. This seems a bit long winded. Would anyone be able to provide some recommendations to this matter?

I would probably say the McKinsey M & A framework as it gives you a breakdown of all the buckets you would probably choose anyway but with a bit more math when it comes to financials.

hey!

For M&A case studies, the key is focusing on value creation and synergy. Start by analyzing the strategic rationale behind the merger or acquisition—why is the deal happening? Consider the strategic fit between the two companies, potential cost synergies, revenue synergies, and the impact on market positioning. Then, assess the financials, focusing on profitability, growth potential, and cost structure. Finally, evaluate the integration challenges, cultural fit, and any risks involved. While analyzing both companies individually can help, streamlining the process to assess strategic fit and synergies will save time and keep the focus on the most critical aspects, as I found in my experience interviewing for roles at firms like McKinsey and BCG.

Hey there,

Some considerations for M&A problems are:

  • Market attractiveness (industry trends, competition considerations, customer analysis, etc.)
  • Financial attractiveness (i.e. profitability of the target company, synergies with acquiring company, acquisition price, ROI, etc.)
  • Feasibility considerations (i.e. capabilities of acquiring company including operational capabilities and expertise, strategic fit and alignment between the two companies, any regulatory concerns, any major barriers of entry, etc. )

Of course you can consider risks (strategic, financial and operational risks) to this. 

Most importantly, you need to tailor your structure to the problem and not use a copy paste framework. 

If you'd like to practice more M&A type questions, or understand the mechanics behind them or any other case problem, feel free to reach out!

All the best

Hi there,

This solely depends on the case context and prompt as every M&A case is unique. If you pre-learn a framework, you will never stand out as an exceptional candidate, who earns an offer.

If you want to receive an offer you need to learn how to create structures from scratch and move towards a first-principles problem-solving approach.

I am quoting a few portions of an article I wrote on the topic:

Why framework memorization fails

1. No points for problem-solving

Case interviews are designed to test your problem-solving and critical-thinking skills, not your ability to regurgitate memorized information. Frameworks are meant to be a guide, not a script. Using a memorized framework can make it obvious that you are not thinking critically about the problem at hand. Interviewers want to see tailored, relevant, and concrete analytical constructs. Using generic categories and ideas not tailored to the case will score poorly in problem-solving.

2. Creative and unique scenarios

Case interviews often involve unique and unpredictable scenarios. No two cases are the same, so a memorized framework will not apply to the specific problem you are presented with. For example:

"You are working with an operator of a specific type of machine. They break down at different rates at different locations. What factors can you think of why that would happen?"

Which Victor Cheng framework or Cosentino idea would you present here? There isn’t a single bucket that would work. We covered that before.

Even in more traditional settings, firms want to see your own perspective, no cookie cutter approach

3. Limiting creativity

Using a memorized framework limits your ability to think creatively. If you always have something to fall back on, then your mind will automatically stop looking at new ideas and angles for a case.

When you try to fit the problem into a pre-existing framework, you may miss opportunities to come up with innovative solutions. Welcome to the 99% of non-offer holders...

4. Lack of rationale

Case interviews also test your ability to communicate and present your thought process effectively. When relying on a memorized framework, you may struggle to explain the reasoning behind your solutions. You have no clear hypotheses.

Interviewers want to understand why you think a certain way, not just what you think. Memorizing frameworks can hinder your ability to support and defend your choices.

The memorized framework approach was developed by Marc Cosentino, a career advisor with no skin in the game who has never seen a consulting firm's office from the inside. When I was at McKinsey there was a saying that his advice is preventing more offers than the actual difficulty of the interviews. Something that makes you think…

There is a reason why only 1% of applicants get the offer, yet everyone continues to rely on the faulty framework approach.

How to change this?

At the core, all consulting firms want to see creative ideas communicated in a structured manner, the more exhaustive the better.

Your goal should be to develop a tailored and creative answer that fits the question. The framework should - broadly speaking - follow these three characteristics:

  • Broad
  • Deep
  • Insightful

You would need to go into detail and qualify your answer with practical examples and more details.

All the best,

Florian
