ACCRETIVEDILUTIVE

Accretive or Dilutive?

A favourite in investment banking interviews, especially M&A and coverage teams, and in corporate development. Merger maths on real-looking term sheets: all-stock, cash, debt and mixed deals, break-even interest rates, synergies needed, combined multiples, exchange ratios and what happens when the market rejects the premium. Call it, then prove it with the numbers.

But Why?

Interviewers do not stop at the first answer. Work through chains of follow-ups and learn the reasoning behind every answer, including why the wrong ones are wrong.
