2.4 Synergies and Accretion/Dilution Analysis
The idea in plain words
When one company buys another, the first question is whether earnings per share go up or down: up is accretive, down is dilutive. The answer depends mostly on how the deal is paid for. Before synergies, a stock deal helps only if the price-to-earnings ratio paid is lower than the buyer’s own. A cash deal helps only if the target’s earnings yield beats the after-tax cost of the debt. Neither test tells you whether the deal creates value.
Key points
■Paying 20x earnings with stock valued at 15x cuts EPS from $10.00 to $9.58; break-even needs $50 million of after-tax synergies.
■The same purchase funded with 6% debt lifts EPS to $10.15, and turns dilutive above a 6.67% pre-tax rate.
■An accretive deal can still destroy value: $750 million in the example.
A closer look
Synergies are the additional value created by combining two companies that neither could achieve alone — cost synergies (eliminating duplicate back-office functions, combining supply chains) and revenue synergies (cross-selling one company’s products to the other’s customer base). Cost synergies are heavily favored in deal models because they are far more predictable and controllable than revenue synergies, which frequently fail to materialize at the scale originally promised to shareholders.
Decision rule
Use accretion as a screen, never as the decision. Screen: all-stock, accretive only if the P/E paid is below your own P/E; cash, accretive only if the target’s earnings yield on the price beats your after-tax cost of debt. Decision: go ahead only if standalone value + present value of achievable synergies − integration costs − price > 0. When the two disagree, trust the value test.
The costliest mistake
Approving a deal because it is accretive. In the all-cash case above, EPS rises 1.5%, yet the acquirer pays 20x earnings. If the target is worth what the acquirer’s own 15x multiple implies, 15 × 150 = $2,250 million, the purchase destroys 3,000 − 2,250 = $750 million of value while lifting EPS. The market prices the $750 million, usually through the acquirer’s share price on announcement; the EPS model never shows it.
Where Experts Disagree: Do Acquisitions Create Value?
The evidence splits by whose value you measure. Andrade, Mitchell and Stafford (Journal of Economic Perspectives, 2001), studying US mergers from 1973 to 1998, found the announcement reaction positive for the combined merging firms and some improvement in post-merger operating performance relative to industry peers.
2.5 The Leveraged Buyout — Why Leverage Changes Everything
The idea in plain words
A leveraged buyout buys a company mostly with borrowed money, which the company’s own cash flow then pays back. It is like buying a rental flat with a loan and letting the rent repay it. If the flat earns more than the loan costs, you keep the difference on a small down payment, so your return is magnified. But the same math runs in reverse: when the business earns less than the debt costs, losses are magnified at the same rate.
Key points
■Return on equity = r_A + (r_A − r_D) × D/E: 12% on assets becomes 21% on equity at 6% debt and D/E of 1.5, and 2% becomes −4%.
■The example deal earns 13.6% unlevered and 20.0% levered.
■US interest deductions are capped at 30% of EBITDA-like income from 2025, which binds in the example’s first two years.
Decision rule
Add debt only while three tests hold: the expected unlevered return clearly exceeds the all-in cost of debt (13.6% against roughly 8% in the example); in a recession case, EBITDA still covers cash interest at least about two times; and leverage in that recession case stays inside the covenant with room to spare. If the business is cyclical, capital-hungry or burning cash, the second and third tests fail first, and the answer is less debt or no deal. The two-times coverage floor is a working heuristic, not a lender’s rule.
The costliest mistake
Underwriting leverage on the base case alone. Run the example deal through a recession (EBITDA dips to $105 million and recovers only to $120 million by Year 5) and exit at 6.0x. Bought all-equity, the investor gets back $1,013.5 million on $950 million (1.07x). Bought with $550 million of debt, the sponsor’s equity is worth 6.0 × 120 − 415.1 = $304.9 million against $400 million invested: 0.76x, a $95.1 million loss. The same asset, the same bad years: leverage turned a small gain into a 24% loss.
