The screen narrows a broad acquisition universe to established businesses with several reinforcing advantages. First, define the relevant niche and verify that the candidate is its market-share leader with a sustainable competitive advantage. Next, require an industry growing at least as quickly as GDP so the company benefits from a structural tailwind rather than fighting secular decline. Evaluate the existing CEO as part of the asset and proceed only when both parties want a genuine partnership. Finally, use conservative leverage and operate within geographies where the investor understands the people, laws, and commercial environment. The combined filters seek stable earnings, manageable downside risk, and multiple paths for management and the investor to improve the business together.
Origin
Michael Fisch said American Securities established the core screen when raising its first private equity fund in 1994 and retained the same fundamental philosophy as the firm scaled. Extracted from Masters in Business.
Core principles
- 01Prefer category leaders with defensible advantages
- 02Invest where industry growth provides a tailwind
- 03Back proven management rather than replacing it
- 04Use modest leverage to protect against downside
- 05Limit investing to markets where the firm has an informational advantage
How to run it
- 1
Define the market niche
Draw the market narrowly enough to identify real competitors, customers, and substitutes. Determine whether the candidate genuinely holds the leading share.
Pro tip Validate leadership using customer and competitor evidence rather than management claims alone.
Watch out A company can appear dominant when the market definition is artificially narrow.
- 2
Test the competitive advantage
Identify why the company leads and whether competitors can copy, bypass, or erode that advantage. Examine margins, customer behavior, production capabilities, and supplier relationships.
Pro tip Look for advantages demonstrated over several business cycles.
Watch out Current market share without a defensible mechanism may be temporary.
- 3
Verify the industry tailwind
Estimate whether the underlying industry can grow at GDP or better. Separate durable demand drivers from short-lived cyclical strength.
Pro tip Use conservative growth assumptions and test multiple scenarios.
Watch out Strong execution may not overcome prolonged structural industry decline.
- 4
Evaluate management alignment
Assess whether the current CEO produced the earnings being valued and wants to remain an active partner. Determine whether management welcomes capital, expertise, and operating support.
Pro tip Discuss difficult operating decisions before signing to reveal how the partnership may function under pressure.
Watch out Do not assume a strong historical operator will welcome an involved investment partner.
- 5
Build a resilient capital structure
Use leverage that the company can service through adverse rate, inflation, and working-capital scenarios. Preserve liquidity for operations, acquisitions, and unexpected disruptions.
Pro tip Model cash requirements rather than relying solely on EBITDA multiples.
Watch out A good company can still fail under an overleveraged balance sheet.
- 6
Confirm the investor's edge
Proceed where the investor understands the legal, commercial, and relationship environment and can remain close to management. Decline opportunities where another local investor should possess a stronger advantage.
Pro tip Treat geographic and sector familiarity as part of underwriting, not merely operational convenience.
Watch out Scale does not automatically create expertise in unfamiliar markets.
In the wild
An investor studies a leading US manufacturer in a niche growing slightly faster than GDP. Customer interviews confirm high switching costs, plant analysis shows a cost advantage, and the founder-CEO wants to retain a substantial investment. The investor then structures modest debt with undrawn liquidity for plant expansion and supply disruptions.
→ The candidate passes the screen because market leadership, tailwinds, management alignment, and financial resilience reinforce one another.
A company has excellent recent margins and an experienced CEO, but its core market is shrinking and its apparent leadership depends on a narrowly defined category. The investor declines rather than assuming operational improvements can reverse the structural headwind.
→ Capital is preserved by enforcing the full screen instead of rationalizing exceptions.
Common mistakes
Treating market share as sufficient
Leadership matters only when it rests on a sustainable competitive advantage and operates within an attractive industry.
Ignoring management as an asset
Replacing the executives responsible for the valued earnings adds execution risk and may destroy important knowledge and relationships.
Maximizing available leverage
Debt sized to favorable conditions can leave an otherwise healthy company unable to absorb higher interest or working-capital needs.
Is it for you?
Best for
It is best for control investors evaluating established companies for long-term platform investments.
Not ideal for
It is not ideal for distressed turnarounds, pre-revenue ventures, or investors seeking speculative macroeconomic bets.
