description

Build institutional-grade comparable company analyses with operating metrics, valuation multiples, and statistical benchmarking in Excel/spreadsheet format. **Perfect for:** - Public company valuation (M&A, investment analysis) - Benchmarking performance vs. industry peers - Pricing IPOs or funding rounds - Identifying valuation outliers (over/under-valued) - Supporting investment committee presentations - Creating sector overview reports **Not ideal for:** - Private companies without comparable public peers - Highly diversified conglomerates - Distressed/bankrupt companies - Pre-revenue startups - Companies with unique business models Use when users need to build comparable company analyses, peer sets, operating metric spreads, trading multiples, and valuation summaries in financial model building workflows.

Comparable Company Analysis

⚠️ CRITICAL: Data Source Priority (READ FIRST)

ALWAYS follow this data source hierarchy:

1. FIRST: Check for MCP data sources - If S&P Kensho MCP, FactSet MCP, or Daloopa MCP are available, use them exclusively for financial and trading information
2. DO NOT use web search if the above MCP data sources are available
3. ONLY if MCPs are unavailable: Then use Bloomberg Terminal, SEC EDGAR filings, or other institutional sources
4. NEVER use web search as a primary data source - it lacks the accuracy, audit trails, and reliability required for institutional-grade analysis

Why this matters: MCP sources provide verified, institutional-grade data with proper citations. Web search results can be outdated, inaccurate, or unreliable for financial analysis.

Overview

This skill teaches Codex to build institutional-grade comparable company analyses that combine operating metrics, valuation multiples, and statistical benchmarking. The output is a structured Excel/spreadsheet that enables informed investment decisions through peer comparison.

Reference Material & Contextualization:

An example comparable company analysis is provided in examples/comps_example.xlsx. When using this or other example files in this skill directory, use them intelligently:

DO use examples for:

• Understanding structural hierarchy (how sections flow)
• Grasping the level of rigor expected (statistical depth, documentation standards)
• Learning principles (clear headers, transparent formulas, audit trails)

DO NOT use examples for:

• Exact reproduction of format or metrics
• Copying layout without considering context
• Applying the same visual style regardless of audience

ALWAYS ask yourself first:

1. "Do you have a preferred format or should I adapt the template style?"
2. "Who is the audience?" (Investment committee, board presentation, quick reference, detailed memo)
3. "What's the key question?" (Valuation, growth analysis, competitive positioning, efficiency)
4. "What's the context?" (M&A evaluation, investment decision, sector benchmarking, performance review)

Adapt based on specifics:

• Industry context: Big tech mega-caps need different metrics than emerging SaaS startups
• Sector-specific needs: Add relevant metrics early (e.g., cloud ARR, enterprise customers, developer ecosystem for tech)
• Company familiarity: Well-known companies may need less background, more focus on delta analysis
• Decision type: M&A requires different emphasis than ongoing portfolio monitoring

Core principle: Use template principles (clear structure, statistical rigor, transparent formulas) but vary execution based on context. The goal is institutional-quality analysis, not institutional-looking templates.

User-provided examples and explicit preferences always take precedence over defaults.

Core Philosophy

"Build the right structure first, then let the data tell the story."

Start with headers that force strategic thinking about what matters, input clean data, build transparent formulas, and let statistics emerge automatically. A good comp should be immediately readable by someone who didn't build it.

⚠️ CRITICAL: Formulas Over Hardcodes + Step-by-Step Verification

Environment — Office JS vs Python:

• If running inside Excel (Office Add-in / Office JS): Use Office JS directly (Excel.run(async (context) => {...})). Write formulas via range.formulas = [["=E7/C7"]], not range.values. No separate recalc step — Excel handles it natively. Use range.format.* for colors/fonts.
• If generating a standalone .xlsx file: Use Python/openpyxl. Write cell.value = "=E7/C7" (formula string).
• Same principles either way — just translate the API calls.
• Office JS merged cell pitfall: Do NOT call .merge() then set .values on the merged range (throws InvalidArgument — range still reports its pre-merge dimensions). Instead write the value to the top-left cell alone, then merge + format the full range:

  ws.getRange("A1").values = [["TECHNOLOGY — COMPARABLE COMPANY ANALYSIS"]];
  const hdr = ws.getRange("A1:H1");
  hdr.merge();
  hdr.format.fill.color = "#1F4E79";
  hdr.format.font.color = "#FFFFFF";
  hdr.format.font.bold = true;
  

Formulas, not hardcodes:

• Every derived value (margin, multiple, statistic) MUST be an Excel formula referencing input cells — never a pre-computed number pasted in
• When using Python/openpyxl to build the sheet: write cell.value = "=E7/C7" (formula string), NOT cell.value = 0.687 (computed result)
• The only hardcoded values should be raw input data (revenue, EBITDA, share price, etc.) — and every one of those gets a cell comment with its source
• Why: the model must update automatically when an input changes. A hardcoded margin is a silent bug waiting to happen.

Verify step-by-step with the user:

• After setting up the structure → show the user the header layout before filling data
• After entering raw inputs → show the user the input block and confirm sources/periods before building formulas
• After building operating metrics formulas → show the calculated margins and sanity-check with the user before moving to valuation
• After building valuation multiples → show the multiples and confirm they look reasonable before adding statistics
• Do NOT build the entire sheet end-to-end and then present it — catch errors early by confirming each section

---

Section 1: Document Structure & Setup

Header Block (Rows 1-3)

Row 1: [ANALYSIS TITLE] - COMPARABLE COMPANY ANALYSIS
Row 2: [List of Companies with Tickers] • [Company 1 (TICK1)] • [Company 2 (TICK2)] • [Company 3 (TICK3)]
Row 3: As of [Period] | All figures in [USD Millions/Billions] except per-share amounts and ratios

Why this matters: Establishes context immediately. Anyone opening this file knows what they're looking at, when it was created, and how to interpret the numbers.

Visual Convention Standards (OPTIONAL - User preferences and uploaded templates always override)

IMPORTANT: These are suggested defaults only. Always prioritize:

1. User's explicit formatting preferences
2. Formatting from any uploaded template files
3. Company/team style guides
4. These defaults (only if no other guidance provided)

Suggested Font & Typography:

• Font family: Times New Roman (professional, readable, industry standard)
• Font size: 11pt for data cells, 12pt for headers
• Bold text: Section headers, company names, statistic labels

Default Color & Shading — Professional Blue/Grey Palette (minimal is better):

• Keep it restrained — only blues and greys. Do NOT introduce greens, oranges, reds, or multiple accent colors. A clean comps sheet uses 3-4 colors total.
• Section headers (e.g., "OPERATING STATISTICS & FINANCIAL METRICS"):
  • Dark blue background (#1F4E79 or #17365D navy)
  • White bold text
  • Full row shading across all columns
• Column headers (e.g., "Company", "Revenue", "Margin"):
  • Light blue background (#D9E1F2 or similar pale blue)
  • Black bold text
  • Centered alignment
• Data rows:
  • White background for company data
  • Black text for formulas; blue text for hardcoded inputs
• Statistics rows (Maximum, 75th Percentile, etc.):
  • Light grey background (#F2F2F2)
  • Black text, left-aligned labels
• That's the whole palette: dark blue + light blue + light grey + white. Nothing else unless the user's template says otherwise.

Suggested Formatting Conventions:

• Decimal precision:
  • Percentages: 1 decimal (12.3%)
  • Multiples: 1 decimal (13.5x)
  • Dollar amounts: No decimals, thousands separator (69,632)
  • Margins shown as percentages: 1 decimal (68.7%)
• Borders: No borders (clean, minimal appearance)
• Alignment: All metrics center-aligned for clean, uniform appearance
• Cell dimensions: All column widths should be uniform/even, all row heights should be consistent (creates clean, professional grid)

Note: If the user provides a template file or specifies different formatting, use that instead.

Section 2: Operating Statistics & Financial Metrics

Core Columns (Start with these)

1. Company - Names with consistent formatting
2. Revenue - Size metric (can be LTM, quarterly, or annual depending on context)
3. Revenue Growth - Year-over-year percentage change
4. Gross Profit - Revenue minus cost of goods sold
5. Gross Margin - GP/Revenue (fundamental profitability)
6. EBITDA - Earnings before interest, tax, depreciation, amortization
7. EBITDA Margin - EBITDA/Revenue (operating efficiency)

Optional Additions (Choose based on industry/purpose)

• Quarterly vs LTM - Include both if seasonality matters
• Free Cash Flow - For capital-intensive or SaaS businesses
• FCF Margin - FCF/Revenue (cash generation efficiency)
• Net Income - For mature, profitable companies
• Operating Income - For businesses with varying D&A
• CapEx metrics - For asset-heavy industries
• Rule of 40 - Specifically for SaaS (Growth % + Margin %)
• FCF Conversion - For quality of earnings analysis (advanced)

Formula Examples (Using Row 7 as example)

// Core ratios - these are always calculated
Gross Margin (F7): =E7/C7
EBITDA Margin (H7): =G7/C7

// Optional ratios - include if relevant
FCF Margin: =[FCF]/[Revenue]
Net Margin: =[Net Income]/[Revenue]
Rule of 40: =[Growth %]+[FCF Margin %]

Golden Rule: Every ratio should be [Something] / [Revenue] or [Something] / [Something from this sheet]. Keep it simple.

Statistics Block (After company data)

CRITICAL: Add statistics formulas for all comparable metrics (ratios, margins, growth rates, multiples).

[Leave one blank row for visual separation]
- Maximum: =MAX(B7:B9)
- 75th Percentile: =QUARTILE(B7:B9,3)
- Median: =MEDIAN(B7:B9)
- 25th Percentile: =QUARTILE(B7:B9,1)
- Minimum: =MIN(B7:B9)

Columns that NEED statistics (comparable metrics):

• Revenue Growth %, Gross Margin %, EBITDA Margin %, EPS
• EV/Revenue, EV/EBITDA, P/E, Dividend Yield %, Beta

Columns that DON'T need statistics (size metrics):

• Revenue, EBITDA, Net Income (absolute size varies by company scale)
• Market Cap, Enterprise Value (not comparable across different-sized companies)

Note: Add one blank row between company data and statistics rows for visual separation. Do NOT add a "SECTOR STATISTICS" or "VALUATION STATISTICS" header row.

Why quartiles matter: They show distribution, not just average. A 75th percentile multiple tells you what "premium" companies trade at.

---

Section 3: Valuation Multiples & Investment Metrics

Core Valuation Columns (Start with these)

1. Company - Same order as operating section
2. Market Cap - Current market valuation
3. Enterprise Value - Market Cap ± Net Debt/Cash
4. EV/Revenue - How much market pays per dollar of sales
5. EV/EBITDA - How much market pays per dollar of earnings
6. P/E Ratio - Price relative to net earnings

Optional Valuation Metrics (Choose based on context)

• FCF Yield - FCF/Market Cap (for cash-focused analysis)
• PEG Ratio - P/E/Growth Rate (for growth companies)
• Price/Book - Market value vs. book value (for asset-heavy businesses)
• ROE/ROA - Return metrics (for profitability comparison)
• Revenue/EBITDA CAGR - Historical growth rates (for trend analysis)
• Asset Turnover - Revenue/Assets (for operational efficiency)
• Debt/Equity - Leverage (for capital structure analysis)

Key Principle: Include 3-5 core multiples that matter for your industry. Don't include every possible metric just because you can.

Formula Examples

// Core multiples - always include these
EV/Revenue: =[Enterprise Value]/[LTM Revenue]
EV/EBITDA: =[Enterprise Value]/[LTM EBITDA]
P/E Ratio: =[Market Cap]/[Net Income]

// Optional multiples - include if data available
FCF Yield: =[LTM FCF]/[Market Cap]
PEG Ratio: =[P/E]/[Growth Rate %]

Cross-Reference Rule

CRITICAL: Valuation multiples MUST reference the operating metrics section. Never input the same raw data twice. If revenue is in C7, then EV/Revenue formula should reference C7.

Statistics Block

Same structure as operating section: Max, 75th, Median, 25th, Min for every metric. Add one blank row for visual separation between company data and statistics. Do NOT add a "VALUATION STATISTICS" header row.

Section 4: Notes & Methodology Documentation

Required Components

Data Sources & Quality:

• Where did the data come from? (S&P Kensho MCP, FactSet MCP, Daloopa MCP, Bloomberg, SEC filings)
• What period does it cover? (Q4 2024, audited figures)
• How was it verified? (Cross-checked against 10-K/10-Q)
• Note: Prioritize MCP data sources (S&P Kensho, FactSet, Daloopa) if available for better accuracy and traceability

Key Definitions:

• EBITDA calculation method (Gross Profit + D&A, or Operating Income + D&A)
• Free Cash Flow formula (Operating CF - CapEx)
• Special metrics explained (Rule of 40, FCF Conversion)
• Time period definitions (LTM, CAGR calculation periods)

Valuation Methodology:

• How was Enterprise Value calculated? (Market Cap + Net Debt)
• What growth rates were used? (Historical CAGR, forward estimates)
• Any adjustments made? (One-time items excluded, normalized margins)

Analysis Framework:

• What's the investment thesis? (Cloud/SaaS efficiency)
• What metrics matter most? (Cash generation, capital efficiency)
• How should readers interpret the statistics? (Quartiles provide context)

---

Section 5: Choosing the Right Metrics (Decision Framework)

Start with "What question am I answering?"

"Which company is undervalued?" → Focus on: EV/Revenue, EV/EBITDA, P/E, Market Cap → Skip: Operational details, growth metrics

"Which company is most efficient?" → Focus on: Gross Margin, EBITDA Margin, FCF Margin, Asset Turnover → Skip: Size metrics, absolute dollar amounts

"Which company is growing fastest?" → Focus on: Revenue Growth %, EBITDA CAGR, User/Customer Growth → Skip: Margin metrics, leverage ratios

"Which is the best cash generator?" → Focus on: FCF, FCF Margin, FCF Conversion, CapEx intensity → Skip: EBITDA, P/E ratios

Industry-Specific Metric Selection

Software/SaaS: Must have: Revenue Growth, Gross Margin, Rule of 40 Optional: ARR, Net Dollar Retention, CAC Payback Skip: Asset Turnover, Inventory metrics

Manufacturing/Industrials: Must have: EBITDA Margin, Asset Turnover, CapEx/Revenue Optional: ROA, Inventory Turns, Backlog Skip: Rule of 40, SaaS metrics

Financial Services: Must have: ROE, ROA, Efficiency Ratio, P/E Optional: Net Interest Margin, Loan Loss Reserves Skip: Gross Margin, EBITDA (not meaningful for banks)

Retail/E-commerce: Must have: Revenue Growth, Gross Margin, Inventory Turnover Optional: Same-Store Sales, Customer Acquisition Cost Skip: Heavy R&D or CapEx metrics

The "5-10 Rule"

5 operating metrics - Revenue, Growth, 2-3 margins/efficiency metrics 5 valuation metrics - Market Cap, EV, 3 multiples = 10 total columns - Enough to tell the story, not so many you lose the thread

If you have more than 15 metrics, you're probably including noise. Edit ruthlessly.

Section 6: Best Practices & Quality Checks

Before You Start

1. Define the peer group - Companies must be truly comparable (similar business model, scale, geography)
2. Choose the right period - LTM smooths seasonality; quarterly shows trends
3. Standardize units upfront - Millions vs. billions decision affects everything
4. Map data sources - Know where each number comes from

As You Build

1. Input all raw data first - Complete the blue text before writing formulas

2. Add cell comments to ALL hard-coded inputs - Right-click cell → Insert Comment → Document source OR assumption

   For sourced data, cite exactly where it came from:

   • Example: "Bloomberg Terminal - MSFT Equity DES, accessed 2024-10-02"
   • Example: "Q4 2024 10-K filing, page 42, line item 'Total Revenue'"
   • Example: "FactSet consensus estimate as of 2024-10-02"
   • Include hyperlinks when possible: Right-click cell → Link → paste URL to SEC filing, data source, or report

   For assumptions, explain the reasoning:

   • Example: "Assumed 15% EBITDA margin based on peer median, company does not disclose"
   • Example: "Estimated Enterprise Value as Market Cap + $50M net debt (from Q3 balance sheet, Q4 not yet available)"
   • Example: "Forward P/E based on street consensus EPS of $3.45 (average of 12 analyst estimates)"

   Why this matters: Enables audit trails, data verification, assumption transparency, and future updates

3. Build formulas row by row - Test each calculation before moving on

4. Use absolute references for headers - $C$6 locks the header row

5. Format consistently - Percentages as percentages, not decimals

6. Add conditional formatting - Highlight outliers automatically

Sanity Checks

• Margin test: Gross margin > EBITDA margin > Net margin (always true by definition)
• Multiple reasonableness:
  • EV/Revenue: typically 0.5-20x (varies widely by industry)
  • EV/EBITDA: typically 8-25x (fairly consistent across industries)
  • P/E: typically 10-50x (depends on growth rate)
• Growth-multiple correlation: Higher growth usually means higher multiples
• Size-efficiency trade-off: Larger companies often have better margins (scale benefits)

Common Mistakes to Avoid

❌ Mixing market cap and enterprise value in formulas ❌ Using different time periods for numerator and denominator (LTM vs quarterly) ❌ Hardcoding numbers into formulas instead of cell references ❌ Hard-coded inputs without cell comments citing the source OR explaining the assumption ❌ Missing hyperlinks to SEC filings or data sources when available ❌ Including too many metrics without clear purpose ❌ Including non-comparable companies (different business models) ❌ Using outdated data without disclosure ❌ Calculating averages of percentages incorrectly (should be median)

---

Section 6: Advanced Features

Dynamic Headers

For columns showing calculations, use clear unit labels:

Revenue Growth (YoY) % | EBITDA Margin | FCF Margin | Rule of 40

Quartile Analysis Benefits

Instead of just mean/median, quartiles show:

• 75th percentile = "Premium" companies trade here
• Median = Typical market valuation
• 25th percentile = "Discount" territory

This helps answer: "Is our target company trading rich or cheap vs. peers?"

Industry-Specific Modifications

Software/SaaS:

• Add: ARR, Net Dollar Retention, CAC Payback Period
• Emphasize: Rule of 40, FCF margins, gross margins >70%

Healthcare:

• Add: R&D/Revenue, Pipeline value, Regulatory status
• Emphasize: EBITDA margins, growth rates, reimbursement risk

Industrials:

• Add: Backlog, Order book trends, Geographic mix
• Emphasize: ROIC, asset turnover, cyclical adjustments

Consumer:

• Add: Same-store sales, Customer acquisition cost, Brand value
• Emphasize: Revenue growth, gross margins, inventory turns

Add complexity only when needed:

• Include quarterly AND LTM if seasonality matters
• Add FCF metrics if cash generation is key story
• Include industry-specific metrics (Rule of 40 for SaaS, etc.)
• Add more statistics rows if you have >5 companies

Section 9: Industry-Specific Additions (Optional)

Only add these if they're critical to your analysis. Most comps work fine with just core metrics.

Software/SaaS: Add if relevant: ARR, Net Dollar Retention, Rule of 40

Financial Services: Add if relevant: ROE, Net Interest Margin, Efficiency Ratio

E-commerce: Add if relevant: GMV, Take Rate, Active Buyers

Healthcare: Add if relevant: R&D/Revenue, Pipeline Value, Patent Timeline

Manufacturing: Add if relevant: Asset Turnover, Inventory Turns, Backlog

Section 10: Red Flags & Warning Signs

Data Quality Issues

🚩 Inconsistent time periods (mixing quarterly and annual)
🚩 Missing data without explanation
🚩 Significant differences between data sources (>10% variance)

Valuation Red Flags

🚩 Negative EBITDA companies being valued on EBITDA multiples (use revenue multiples instead)
🚩 P/E ratios >100x without hypergrowth story
🚩 Margins that don't make sense for the industry

Comparability Issues

🚩 Different fiscal year ends (causes timing problems)
🚩ixing pure-play and conglomerates
🚩 Materially different business models labeled as "comps"

When in doubt, exclude the company. Better to have 3 perfect comps than 6 questionable ones.

Key Principles Summary

1. Structure drives insight - Right headers force right thinking
2. Less is more - 5-10 metrics that matter beat 20 that don't
3. Choose metrics for your question - Valuation analysis ≠ efficiency analysis
4. Statistics show patterns - Median/quartiles reveal more than average
5. Transparency beats complexity - Simple formulas everyone understands
6. Comparability is king - Better to exclude than force a bad comp
7. Document your choices - Explain which metrics and why in notes section

---

Output Checklist

Before delivering a comp analysis, verify:

• All companies are truly comparable
• Data is from consistent time periods
• Units are clearly labeled (millions/billions)
• Formulas reference cells, not hardcoded values
• All hard-coded input cells have comments with either: (1) exact data source with citation, OR (2) clear assumption with explanation
• Hyperlinks added where relevant (SEC EDGAR filings, Bloomberg pages, research reports)
• Statistics include at least 5 metrics (Max, 75th, Med, 25th, Min)
• Notes section documents sources and methodology
• Visual formatting follows conventions (blue = input, black = formula)
• Sanity checks pass (margins logical, multiples reasonable)
• Date stamp is current ("As of [Date]")
• Formula auditing shows no errors (#DIV/0!, #REF!, #N/A)

---

Continuous Improvement

After completing a comp analysis, ask:

1. Did the statistics reveal unexpected insights?
2. Were there any data gaps that limited analysis?
3. Did stakeholders ask for metrics you didn't include?
4. How long did it take vs. how long should it take?
5. What would make this more useful next time?

The best comp analyses evolve with each iteration. Save templates, learn from feedback, and refine the structure based on what decision-makers actually use.
