model-update
The facts
Its description
Update financial models with new data — quarterly earnings, management guidance, macro changes, or revised assumptions. Adjusts estimates, recalculates valuation, and flags material changes. Use after earnings, guidance updates, or when assumptions need refreshing. Triggers on "update model", "plug earnings", "refresh estimates", "update numbers for [company]", "new guidance", or "revise estimates".
The description the agent reads to decide when to use it.
When it starts
The agent picks this when someone wants an existing financial model or estimate set refreshed after new information — quarterly earnings, new guidance, macro moves, or changed assumptions — and wants the valuation and price target recalculated. The description frames it as a follow-on task, so it fires on requests to plug in actuals or revise forward numbers rather than to build a model from scratch.
Things a person might say (the model's guesses)
- “Plug Q3 earnings into my model for Costco and update the price target.”
- “The company just cut guidance — refresh my estimates and tell me whether the rating changes.”
- “Rates and FX moved a lot this quarter; update the numbers in my model and flag anything material.”

Model Update
Raw lines 1 to 7Workflow
Raw lines 8 to 9Step 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 |
Step 5: Summary & Action
Estimate Change Summary:
- One paragraph: what changed, why, and what it means for the stock
- Is this a thesis-changing event or noise?
Rating / Price Target:
- Maintain or change rating?
- New price target (if changed) with methodology
- Upside/downside to current price
Step 6: Output
- Updated Excel model (if user provides the existing model)
- Estimate change summary (markdown or Word)
- Updated price target derivation
Important Notes
- Always reconcile your estimates to the company's reported figures before projecting forward
- Note any non-recurring items and whether your estimates are GAAP or adjusted
- Track your estimate revision history — it shows your analytical progression
- If the quarter was noisy, separate signal from noise in your estimate changes
- Check consensus after updating — how do your revised estimates compare to the Street?
- Share count matters — dilution from stock comp, converts, or buybacks can materially affect EPS
