Mergers and acquisitions - the arithmetic of deal math

m-a.wiki

A machine-readable reference for M&A deal math: LBO returns and the four-way value-creation bridge, accretion/dilution with breakeven-PE rules, the enterprise-to-equity purchase price bridge, agreement mechanics, and valuation cross-checks. Every entry that involves arithmetic states the formula and works it with numbers that tie.

Deal math is usually taught as narrative and then applied as a spreadsheet, and the gap between the two is where most errors live. This reference states the arithmetic first. Every worked example is internally consistent and ties to the bridge it claims to explain. Notation is uniform throughout: EV is enterprise value, E is equity value, D is the gross debt balance, C is cash, ND is net debt (D - C), EBITDA is earnings before interest, tax, depreciation and amortisation, x_entry and x_exit are the entry and exit EV/EBITDA multiples, t is the holding period in years, r is a discount rate or WACC, g is a growth rate, tau is the marginal tax rate, IRR is the internal rate of return, MOIC is multiple on invested capital, NI is net income, S is the fully diluted share count, P is price per share, and EPS is NI/S. Subscript 0 denotes entry or the pre-deal state and subscript t denotes exit or the pro forma state. Nothing here is a market-terms survey or a multiples benchmark: no leverage level, premium, or multiple appearing below is presented as a measured market statistic. Where a convention exists it is named as a convention. Where a rule comes from a statute or accounting standard it is cited by section.

Reference information only. Not legal, tax, or investment advice. Acquisition agreements, credit documents, and tax structures vary materially between transactions and jurisdictions; the mechanics described here are common patterns, not the terms of any particular deal. Worked examples use assumed inputs chosen to make the arithmetic verifiable, not to represent market levels. Consult counsel.
