Why PE Case Studies Matter
Private equity case studies are among the most challenging components of PE interview processes. Unlike investment banking interviews that focus heavily on technical questions with clear right answers, PE case studies test your ability to think like an investor—evaluating real companies, identifying value creation opportunities, and making investment recommendations under time pressure.
These exercises appear in nearly every PE interview process, particularly at:
- Growth equity firms
- Buyout funds
- Late-stage interview rounds
- On-site final rounds
Case studies test multiple competencies simultaneously:
- Investment judgment: Can you identify what makes a good or bad investment?
- Analytical thinking: Can you work through complex information systematically?
- Communication skills: Can you present recommendations clearly to partners?
- Time management: Can you prioritize under pressure?
- Business intuition: Do you understand value drivers and risks?
A strong case study performance can override minor weaknesses elsewhere. A weak performance—even with perfect technical skills—can eliminate you from consideration.
Types of PE Case Studies
1. Take-Home Case Studies
Format: Receive materials in advance (1-3 days before), prepare analysis, present findings on-site
Common materials:
- Company overview and financial statements
- Industry information
- Management presentation
- Market data
Typical time allocation: 3-8 hours of preparation
Deliverable: Usually a presentation (10-15 slides) plus discussion
2. On-Site Case Studies
Format: Receive materials on arrival, analyze for 2-4 hours, present to interview team
Similar materials to take-home but compressed timeline
Challenge: Must work quickly and prioritize key analyses
3. Live Case Discussions
Format: Verbal case without materials, discuss investment framework in real-time
Example: "Walk me through how you'd evaluate a potential investment in a SaaS company in the education space."
Focus: Framework and thinking process over detailed analysis
Understanding the complete IB and PE interview process helps you recognize where case studies fit and how they complement other interview components like technical questions and behavioral discussions.
The Universal PE Case Study Framework
Regardless of format, use this systematic approach for every case study:
Step 1: Understand the Investment Thesis (10-15% of time)
Before diving into numbers, understand the fundamental question:
Key questions to answer:
- What type of investment is this? (Buyout, growth equity, minority stake)
- What stage is the company? (Early growth, mature, turnaround)
- What's the basic investment thesis? (Market leader, consolidation play, operational fix)
- What's the expected holding period and exit strategy?
Why this matters: Your entire analysis flows from understanding what kind of investment this is. A growth equity investment in an early-stage SaaS company requires different analysis than a mature buyout of an industrial distribution business.
Step 2: Analyze the Business Model (20-25% of time)
Understand how the company makes money and what drives value:
Key areas to evaluate:
Revenue Model:
- How does the company generate revenue?
- Is it recurring or transactional?
- What are unit economics?
- How sticky are customers?
Competitive Position:
- What's the company's market position?
- What are barriers to entry?
- Who are key competitors?
- What's the differentiation?
Market Dynamics:
- Is the market growing or mature?
- What are key trends affecting the industry?
- Are there regulatory or technological disruptions?
Management Team:
- Is management capable and aligned?
- What's their track record?
- Will they stay post-acquisition?
Step 3: Financial Analysis (25-30% of time)
Examine historical performance and future potential:
Historical Performance:
- Revenue growth trends
- Margin evolution (gross margin, EBITDA margin)
- Working capital trends
- Cash flow generation
- Key performance indicators (KPIs) specific to the business
Quality of Earnings:
- Are revenues sustainable?
- Are margins normal or artificially inflated/depressed?
- Are there one-time items affecting profitability?
- How do metrics compare to competitors?
Financial Projections:
- What growth rates are reasonable?
- What margin expansion is achievable?
- What capital expenditure is required?
- What working capital needs exist?
Red Flags to Watch For:
- Declining revenue or margins
- Customer concentration
- Deteriorating working capital
- High customer churn
- Accounting irregularities
Step 4: Value Creation Plan (20-25% of time)
This is the most important section—how will the PE firm create value?
The Three Value Creation Levers:
1. Revenue Growth
- Organic growth (market expansion, new products, pricing)
- Geographic expansion
- New customer segments
- Add-on acquisitions
2. Operational Improvements
- Margin expansion through cost reduction
- Process optimization
- Technology implementation
- Working capital management
3. Financial Engineering
- Optimal capital structure
- Debt paydown through cash generation
- Multiple expansion (buy low, sell high)
Prioritize: Identify the 3-5 most impactful initiatives. Don't create a 20-point plan—focus on what matters most.
Be realistic: Can management actually execute these improvements? What's required to succeed?
Step 5: Risk Assessment (10-15% of time)
Strong candidates don't just pitch—they acknowledge risks:
Key risks to evaluate:
Market Risks:
- Economic sensitivity
- Competitive threats
- Technological disruption
- Regulatory changes
Execution Risks:
- Integration challenges (if add-ons planned)
- Management capability
- Customer retention
- Operational complexity
Financial Risks:
- Leverage levels
- Cash flow volatility
- Covenant compliance
- Exit market conditions
How to present risks: For each major risk, explain potential mitigation strategies.
Step 6: Investment Recommendation (10% of time)
Make a clear recommendation and defend it:
Your conclusion should address:
- Investment decision: Yes, no, or maybe (if more diligence needed)
- Key drivers: What 2-3 factors most influence your decision?
- Expected returns: Qualitative assessment (don't need exact IRR without modeling)
- Exit strategy: How would you eventually exit this investment?
- Deal breakers: What would change your recommendation?

How to Structure Your Presentation
Whether presenting in person or submitting materials, use this structure:
Slide 1: Executive Summary
Include:
- Investment recommendation (invest / pass / more diligence needed)
- Deal overview (company, industry, transaction size)
- 3-4 key reasons supporting your recommendation
- Major risks or concerns
Keep it to one slide—this is your headline
Slides 2-3: Company & Market Overview
Company overview:
- Business model and products/services
- Key metrics and performance highlights
- Management team
Market overview:
- Industry size and growth
- Competitive landscape
- Key trends
Slides 4-6: Financial Analysis
Historical performance:
- Revenue and growth trends
- Profitability evolution
- Key metrics vs. benchmarks
Quality and sustainability:
- One-time items or adjustments
- Comparison to peers
- Assessment of projections
Slides 7-9: Value Creation Plan
This is your most important section:
- 3-5 specific value creation initiatives
- Expected impact of each (qualitative or quantitative)
- Timeline and resources required
- Execution risks for each initiative
Be specific: Don't just say "improve margins." Say "consolidate three distribution centers into one, reducing logistics costs by estimated 15%, achievable within 18 months with $5M investment."
Slides 10-11: Risk Assessment
Major risks:
- 3-5 key risks with mitigation strategies
- Sensitivity analysis if time permits
- Key assumptions to validate in further diligence
Slide 12: Investment Recommendation & Next Steps
Recommendation:
- Clear yes/no/maybe with supporting rationale

How to Present Your Case Study
1. Lead with Your Recommendation
Don't build suspense. Start with your conclusion:
"I recommend we pursue this investment for three primary reasons..."
This frames the entire discussion and shows decisiveness.
2. Tell a Story
Don't just recite slides. Create a narrative:
"This is a market-leading SaaS business in an attractive vertical. While growth has been strong at 40% annually, we see three specific opportunities to accelerate while improving unit economics..."
3. Be Prepared for Interruptions
Partners will interrupt with questions. This is normal—they're testing your thinking:
- Don't get flustered: Pause, answer directly, then return to your narrative
- Admit what you don't know: "That's a good question. I didn't have data on that, but here's how I'd approach evaluating it..."
- Connect to your thesis: "That risk is exactly why I recommend focusing our value creation plan on..."
4. Show Your Work
Explain your reasoning, not just conclusions:
Weak: "Revenue will grow 20% annually."
Strong: "I'm projecting 20% revenue growth based on three factors: the market is growing 10-12% annually, the company is gaining share given product superiority, and there's a 2-year backlog of large enterprise deals in the pipeline."
5. Engage in Discussion
The case study isn't a one-way presentation. Treat it as a collaborative discussion:
- Ask clarifying questions if needed
- Acknowledge good points from interviewers
- Show you can incorporate feedback
- Demonstrate you're coachable
Practice case discussions and frameworks: Beyond case studies, PE interviews require mastery of exit strategies, valuation approaches, and ability to discuss deals you've followed—all of which complement your case study analysis.
Common Mistakes to Avoid
1. Analysis Paralysis
The Problem: Spending 90% of time on financial modeling, 10% on value creation and presentation.
Why it fails: Financial analysis is necessary but not sufficient. Partners care most about your investment judgment and value creation ideas.
The Solution: Set time limits for each section and stick to them.
2. No Clear Recommendation
The Problem: Ending with "it depends" or "I need more information."
Why it fails: PE is about making decisions with imperfect information. You must take a stance.
The Solution: Make a clear recommendation (yes/no/more diligence needed) and defend it with supporting rationale.
3. Generic Value Creation Plans
The Problem: Vague statements like "improve operations" or "grow revenue" without specifics.
Why it fails: Shows lack of business understanding and analytical depth.
The Solution: Be specific about initiatives, expected impact, timeline, and required resources.
4. Ignoring Risks
The Problem: Only presenting upside without acknowledging what could go wrong.
Why it fails: Suggests naive thinking or inability to assess risk.
The Solution: For every case study, explicitly discuss 3-5 major risks and mitigation strategies.
5. Poor Presentation Skills
The Problem: Reading slides, rambling, defensive body language when questioned.
Why it fails: Communication skills matter enormously—you need to pitch deals to investment committees.
The Solution: Practice presenting. Record yourself. Get feedback. Be conversational and confident.
6. Focusing on Irrelevant Details
The Problem: Deep dive into minor issues while missing major value drivers.
Why it fails: Shows poor business judgment and inability to prioritize.
The Solution: Always ask: "What matters most for this investment decision?" Focus there.
Preparation Strategy
1. Practice Real Case Studies
Sources for practice cases:
- Firm websites (some publish sample cases)
- Case interview prep books (consulting cases can be adapted)
- Past LBO models from banking (convert to case study format)
- Create your own from public company 10-Ks
Practice routine:
- Time yourself strictly
- Present to friends or mentors
- Get feedback on structure and content
- Refine your approach
2. Study Real PE Deals
Read about actual PE investments:
- Which companies did major PE firms acquire?
- What was the investment thesis?
- How did they create value?
- What was the exit outcome?
Sources:
- PE firm websites (portfolio companies and case studies)
- PE trade publications (PE Hub, Buyouts Magazine)
- Deal announcements and investor presentations
3. Build Pattern Recognition
After practicing multiple cases, you'll recognize patterns:
- High-growth companies → focus on unit economics and scalability
- Mature businesses → focus on operational improvements and add-ons
- Fragmented industries → focus on consolidation plays
- Turnarounds → focus on stabilization and repositioning
4. Develop Your Template
Create a standard slide template you can adapt quickly:
1. Executive Summary
2. Company & Market Overview
3. Financial Analysis
4. Value Creation Plan
5. Risk Assessment
6. Recommendation & Next Steps
Having a template saves time and ensures consistency.
Key Takeaways
- Use a systematic framework for every case: understand thesis → analyze business → financial analysis → value creation → risks → recommendation
- Allocate time wisely: don't spend 90% on financial analysis
- Be specific in value creation plans: avoid generic statements
- Make a clear recommendation and defend it
- Acknowledge risks and discuss mitigation strategies
- Practice extensively: case studies improve dramatically with repetition
- Present confidently and engage in discussion
Conclusion
Private equity case studies are challenging because they test everything at once: analytical skills, business judgment, communication ability, and investment thinking. There's rarely a single "right answer"—success comes from demonstrating a structured approach, thoughtful analysis, and clear communication.
The best candidates treat case studies as an opportunity to show how they think, not just what they know. They balance quantitative analysis with qualitative judgment. They make clear recommendations while acknowledging uncertainty. They present confidently while remaining open to discussion.
Start practicing now. Work through real cases under time pressure. Present to others and get feedback. Build your framework and refine your approach. When you face your first PE case study, you'll be ready to demonstrate that you can think and communicate like an investor.
