# Model Update

## Workflow

### Step 1: Identify What Changed

Determine the update trigger:
- **Earnings release**: New quarterly actuals to plug in
- **Guidance change**: Company updated forward outlook
- **Estimate revision**: Analyst changing assumptions based on new data
- **Macro update**: Interest rates, FX, commodity prices changed
- **Event-driven**: M&A, restructuring, new product, management change

### Step 2: Plug New Data

#### After Earnings
Update the model with reported actuals:

| Line Item | Prior Estimate | Actual | Delta | Notes |
|-----------|---------------|--------|-------|-------|
| Revenue | | | | |
| Gross Margin | | | | |
| Operating Expenses | | | | |
| EBITDA | | | | |
| EPS | | | | |
| [Key metric 1] | | | | |
| [Key metric 2] | | | | |

**Segment Detail** (if applicable):
- Update each segment's revenue and margin
- Note any segment mix shifts

**Balance Sheet / Cash Flow Updates**:
- Cash and debt balances
- Share count (buybacks, dilution)
- Capex actual vs. estimate
- Working capital changes

### Step 3: Revise Forward Estimates

Based on the new data, adjust forward estimates:

| | Old FY Est | New FY Est | Change | Old Next FY | New Next FY | Change |
|---|-----------|-----------|--------|------------|------------|--------|
| Revenue | | | | | | |
| EBITDA | | | | | | |
| EPS | | | | | | |

**Key Assumption Changes:**
- What assumptions are you changing and why?
- Revenue growth rate: old → new (reason)
- Margin assumption: old → new (reason)
- Any new items (restructuring charges, one-time gains, etc.)

### Step 4: Valuation Impact

Recalculate valuation with updated estimates:

| Valuation Method | Prior | Updated | Change |
|-----------------|-------|---------|--------|
| DCF fair value | | | |
| P/E (NTM EPS × target multiple) | | | |
| EV/EBITDA (NTM EBITDA × target multiple) | | | |
| **Price Target** | | | |
