Build a multi-tab Excel financial model
Build a comprehensive Excel financial model (.xlsx) for the company named in the user's request. If no ticker or company is provided, ask for one before proceeding. **Before starting, read `../data-access.md` for data access methods and `../design-system.md` for formatting conventions.** Follow the data access detection logic and design system throughout this skill. This skill gathers all available financial data and builds a multi-tab Excel model saved as `reports/{TICKER}_model.xlsx`. ## Phase 1 — Company Setup Look up the company by ticker using `discover_companies`. Capture: - `company_id` - `latest_calendar_quarter` — anchor for all period calculations (see `../data-access.md` Section 1.5) - `latest_fiscal_quarter` - Firm name for report attribution (default: "Daloopa") — see `../data-access.md` Section 4.5 Get current stock price, market cap, shares outstanding, beta, and trading multiples for {TICKER}. Use the 3-step resolution: (1) MCP market data tools if available, (2) web search, (3) sensible defaults (see `../data-access.md` Section 2). ## Phase 2 — Comprehensive Data Pull Calculate periods backward from `latest_calendar_quarter`. Pull as much data as Daloopa has for this company. Target 8-16 quarters. **Income Statement — search and pull all available:** - Revenue / Net Sales - Cost of Revenue / COGS - Gross Profit - Research & Development - Selling, General & Administrative - Total Operating Expenses - Operating Income - Interest Expense / Income - Pre-tax Income - Tax Expense - Net Income - Diluted EPS - Diluted Shares Outstanding - EBITDA (or compute from Op Income + D&A) - D&A **Balance Sheet — search and pull all available:** - Cash and Equivalents - Short-term Investments - Accounts Receivable - Inventory - Total Current Assets - PP&E (net) - Goodwill - Total Assets - Accounts Payable - Short-term Debt - Long-term Debt - Total Liabilities - Total Equity **Cash Flow — search and pull all available:** - Operating Cash Flow - Capital Expenditures - Depreciation & Amortization - Acquisitions - Dividends Paid - Share Repurchases - Free Cash Flow (compute if not direct) **Segments:** - Revenue by segment - Operating income by segment (if available) **KPIs:** - All company-specific operating metrics **Guidance:** - All guidance series and corresponding actuals ## Phase 3 — Market Data & Peers - Identify 5-8 peers and get their trading multiples using the same 3-step resolution: (1) MCP market data tools, (2) web search, (3) sensible defaults - Get risk-free rate using the same 3-step resolution - If consensus forward estimates are available (`../data-access.md` Section 3), include NTM estimates for peers ## Phase 4 — Projections Build forward estimates using the following methodology: - **Revenue:** Start with latest guidance (if available), then decay to long-term growth rate (industry average or historical trend). Apply quarterly seasonality patterns from trailing data. - **Gross Margin:** Mean-revert to trailing 8-quarter average, with adjustment for recent trends or guidance commentary. - **Operating Expenses:** Project as % of revenue, trending toward trailing averages. R&D and SG&A may have different trajectories. - **CapEx:** Project as % of revenue based on trailing 4-8 quarter average and guidance. - **D&A:** Project based on trailing average as % of revenue or PP&E. - **Tax Rate:** Use trailing effective tax rate or guidance. - **Share Count:** Project dilution/buyback based on trailing trends and guidance. - **Working Capital:** Project DSO, DIO, DPO based on trailing averages. Calculate all quarterly projections, then sum to annual. Project 4-8 quarters forward. ## Phase 5 — DCF Inputs Calculate: - **WACC:** Use CAPM for cost of equity (Rf + Beta × ERP, where ERP = 6.0%). Cost of debt = Interest Expense / Total Debt. WACC = (E/V × Re) + (D/V × Rd × (1 - Tax Rate)). - **5-year FCF projections:** Annualize from quarterly projections (FCF = Op Cash Flow - CapEx). - **Terminal Value:** Use perpetuity growth at 2.5-3.0%. - **Sensitivity Matrix:** WACC (7 values: -3% to +3% from base) × Terminal Growth (6 values: 1.5% to 4.0%). ## Phase 6 — Build Excel Model Generate the `.xlsx` file directly using the best available spreadsheet-generation workflow. For Codex, prefer bundled spreadsheet tooling or Python/openpyxl when available. The workbook should: 1. Create 8 tabs with the following structure: **Tab 1: Income Statement** - Rows: Revenue, COGS, Gross Profit, R&D, SG&A, Total OpEx, Op Income, Interest, Pre-Tax Income, Tax, Net Income, Diluted EPS, Shares - Columns: Historical periods (8-16Q) + Projected periods (4-8Q) - Sub-rows: YoY growth %, margin % where applicable - Header: Company name, ticker, report date - Formatting: Numbers with commas/decimals, percentages, bold headers, frozen panes **Tab 2: Balance Sheet** - Rows: Assets section (Cash, Investments, AR, Inventory, Current Assets, PP&E, Goodwill, Total Assets), Liabilities section (AP, ST Debt, LT Debt, Total Liabilities, Equity) - Columns: Historical + Projected periods - Sub-rows: % of Total Assets for key line items - Same formatting standards **Tab 3: Cash Flow** - Rows: Op Cash Flow, CapEx, Free Cash Flow, Acquisitions, Dividends, Buybacks, Net Change in Cash - Columns: Historical + Projected periods - Sub-rows: FCF yield %, CapEx as % Revenue - Same formatting standards **Tab 4: Segments** - Rows: Revenue by segment, Op Income by segment (if available) - Columns: Historical + Projected periods - Sub-rows: Segment as % of total, segment growth rates - Same formatting standards **Tab 5: KPIs** - Rows: All company-specific operating metrics discovered - Columns: Historical + Projected periods - Sub-rows: YoY growth or relevant unit economics - Same formatting standards **Tab 6: Projections** - Editable assumption inputs (yellow highlighting): Revenue growth %, Gross margin %, Op margin %, CapEx % revenue, Tax rate %, Buyback rate QoQ - Calculated outputs: Projected P&L, BS, CF driven by assumptions - Commentary box explaining methodology - Same formatting standards **Tab 7: DCF** - Inputs: WACC, Terminal Growth, Risk-Free Rate, ERP, Beta, Cost of Debt - FCF Projection (5 years annualized) - Terminal Value calculation - PV calculations - Enterprise Value → Equity Value → Implied Share Price - Sensitivity table: WACC (rows) × Terminal Growth (cols) showing implied price - Color scale: green (upside) to red (downside) vs current price - Same formatting standards **Tab 8: Summary** - Company overview (name, ticker, sector, description) - Current market data (price, market cap, shares, beta) - Valuation summary: DCF implied price, peer-implied range, current price, upside/downside % - Peer trading multiples table - Key model outputs: Trailing revenue, Projected revenue growth, Trailing/Projected margins - Same formatting standards 2. Apply `../design-system.md` formatting conventions: - Number format: $X.Xbn for large numbers, X.X% for percentages, X.Xx for multiples - Color palette: Navy #1B2A4A (headers), Steel Blue #4A6FA5 (sub-headers), Gold #C5A55A (highlights), Green #27AE60 (positive), Red #C0392B (negative) - Bold headers, frozen top row and left column - Yellow fill (#FFEB3B) for editable input cells 3. Save the workbook as `reports/{TICKER}_model.xlsx` ## Output Save the generated workbook to `reports/{TICKER}_model.xlsx` and tell the user: - Summary of what tabs were built - Key model outputs: trailing revenue, projected revenue growth, implied DCF value, peer-implied range - Note that yellow cells in the Projections tab are editable inputs - Instruction to open the saved `.xlsx` file All financial figures gathered must use Daloopa citation format: [$X.XX million](https://daloopa.com/src/{fundamental_id})
