Acquisition Criteria

Berkshire's published framework for evaluating potential acquisitions — a rare example of a conglomerate committing publicly to consistent capital allocation principles.

Buffett’s Own Words

We want businesses with (1) large purchases (at least $75 million of pre-tax earnings), (2) demonstrated consistent earning power, (3) businesses earning good returns on equity while employing little or no debt, (4) management in place (we can't supply it), (5) simple businesses, (6) an offering price.

Concept Analysis

Definition & Origins

Berkshire's acquisition philosophy is built on a simple promise made public and maintained consistently for six decades: we will be a good permanent home for businesses built by families who care about legacy, operated by managers who love their work, and priced at terms reflecting genuine long-term value. No auctions when possible, no management replacement without cause, no resale, and decisions made in hours not months. This combination — unusual terms offered with certainty — has made Berkshire the preferred buyer for a specific type of seller.

Core Ideas

Four criteria, maintained for 60 years. Buffett's acquisition criteria are explicitly stated: (1) businesses he understands; (2) durable competitive advantages; (3) managers he trusts, in place and committed; (4) prices that make sense relative to intrinsic value. He has rejected hundreds of opportunities that fail any single criterion, regardless of how attractive the others appear.

The institutional imperative destroys acquisition discipline. CEOs who complete large acquisitions receive analyst coverage, press attention, and board congratulation. CEOs who pass on acquisitions receive nothing. This asymmetric reward structure systematically biases corporate behavior toward deal-making at any price. Buffett's antidote: require that every acquisition dollar produce at least $1 of intrinsic value at closing.

Stock-financed acquisitions are doubly dangerous. When paying in stock, Berkshire is implicitly selling a fraction of all its existing businesses at today's price. This is rational only when what is received in exchange is worth at least as much. Buffett's Dexter Shoe acquisition — paid entirely in Berkshire stock that subsequently appreciated enormously — illustrates the catastrophic cost of using underpriced currency.

Practical Application

Berkshire's acquisition process is deliberately simple: businesses send a one-page description; Buffett reads it and responds within 24 hours with a yes or no. If meeting is warranted, it often happens within a week. The due diligence for the McLane acquisition from Walmart was a single phone call and a handshake — both parties trusted the other completely. This speed and certainty is itself a competitive advantage in the market for family business sales.

Common Misconceptions

Misconception 1: Acquisitions create synergies that justify premium prices. The majority of acquisition synergies projected at announcement are never fully realized. Integration costs, management distraction, cultural friction, and competitive responses routinely consume the projected synergy value. Buffett's approach: pay only for what exists today, treat any synergies as a bonus he didn't pay for.

Misconception 2: Berkshire wins acquisitions because of its price. Berkshire often does NOT pay the highest price. It wins desirable acquisitions because it offers something worth more to certain sellers than additional premium: certainty (no financing conditions), permanence (no resale), and autonomy (no management replacement). For families who built businesses over generations, these terms can be worth tens of millions in price reduction.



Thought Evolution

Early acquisitions (1965–1985)
National Indemnity, See's Candies, Buffalo News — Buffett building the Berkshire model through small- to mid-sized acquisitions in sectors he understood deeply.
Scaling up (1985–2005)
Capital Cities/ABC, GEICO, General Re, NetJets, Clayton Homes — larger and more complex transactions, sometimes using stock, always following the same four criteria.
Elephant-hunting era (2006–2015)
ISCAR, Marmon Group, BNSF, Lubrizol, Precision Castparts — multi-billion acquisitions of outstanding industrial and energy businesses, as Berkshire's cash generation required larger deployments.
