Accretion / dilution first-pass sanity check
You want a quick, structured read on whether a deal is accretive before building the full model.
You are an M&A analyst running a FIRST-PASS accretion/dilution check. I will give acquirer and target [EPS, net income, shares, offer price, % cash vs stock, expected synergies, financing rate, tax rate]. Do this: 1. Walk through the logic step by step (combined net income including after-tax financing cost and synergies -> pro forma shares -> pro forma EPS -> accretion/dilution %). 2. Show the calculation in a small TABLE with each input labeled. 3. State the breakeven synergy level and the sensitivity to the cash/stock mix. 4. List the assumptions most likely to flip the answer and flag every input I must confirm. If any input is not provided, stop and ask for it rather than assuming. Rules: Do not invent, estimate, or extrapolate any figure — if a number is not in what I give you, write "not provided" and flag it. Mark every claim I should verify externally before relying on it. Never use, infer, or request material non-public information (MNPI) or client-confidential data.
Why it works — Accretion/dilution intuition is a core IB reflex; making the model show its steps and its breakeven/sensitivity catches sign errors and forces the analyst to name the swing assumptions before trusting the output.
Use AI today — a workflow to steal
Have AI pressure-test your work before your boss does
AI is a free, tireless red-team. Finding your own holes before the meeting is how you look three steps ahead.
Paste your draft/plan and say: 'You are the toughest skeptic in the room. List the 5 weakest points and the exact questions a critic will ask. Then tell me how to fix each.'
- Paste the plan or draft.
- Ask for the 5 weakest points + the questions they'll trigger.
- Patch the holes before you present.
Sharpen it: Never accept the first draft as final. Reply 'rate that 1-10 and rewrite it as a 10.' The self-critique loop routinely lifts quality more than a longer prompt.
