Acquisition Target Screening: Filters, Criteria & Frameworks

Effective screening is the difference between reviewing 200 businesses in 18 months and reviewing 50 in 6. A systematic screening process eliminates poor fits quickly, letting you spend time where it matters, deep evaluation of the 10-20% of deals that could be your acquisition. According to the Stanford GSB 2024 Search Fund Study, searchers who closed acquisitions reviewed a median of 83 opportunities before submitting an LOI, underscoring the importance of an efficient screening process. This guide provides a complete screening framework.

The screening funnel

The typical search fund funnel:

1. Universe: 500-2,000 businesses identified through sourcing channels
2. Tier 1 screen (30 seconds): 200-400 pass basic criteria
3. Tier 2 screen (15 minutes): 50-100 warrant CIM review
4. Tier 3 evaluation (2-5 hours): 15-30 deserve deep analysis
5. Seller meetings: 5-15 in-person meetings
6. LOI submissions: 3-8 LOIs submitted
7. Acquisition: 1 closed deal

Tier 1: Instant pass/fail filters

Apply these in 30 seconds from a teaser or listing:

• Revenue: Does it meet your minimum threshold? (e.g., $3M+ for traditional search)
• EBITDA/SDE: Above your floor? (e.g., $1M+ EBITDA)
• Industry: In one of your thesis industries?
• Geography: In a location where you’re willing to live?
• Asking price: Does the implied multiple make sense? (>8x EBITDA = pass for most SMEs)
• Reason for sale: Retirement/succession (good) vs. distress/regulatory (investigate)

Tier 2: CIM-level screening

After signing the NDA and receiving the CIM, spend 15-30 minutes on:

Financial quick-check

• Revenue trend: 3-5 year trajectory. Growing, stable, or declining?
• EBITDA margin: Is it consistent with industry norms? Volatile margins are a warning sign
• Add-backs: Are the seller’s EBITDA add-backs reasonable or aggressive?
• Capex: Maintenance capex requirements. Has the seller been underinvesting?

Structural quick-check

• Customer concentration: Top customer >25% of revenue? Flag or pass
• Owner dependency: Is there a management layer? Or does everything run through the owner?
• Revenue model: Recurring, repeat, or one-time? Contract length and renewal rates?
• Employee count: Too few (<10) may mean owner-operated; too many (>200) may be complex for a first-time CEO

Tier 3: Deep evaluation

For the 15-30 businesses that pass Tier 2, invest 2-5 hours per opportunity:

Financial deep dive

• Recalculate adjusted EBITDA from raw financials (don’t trust the CIM)
• Analyze monthly revenue trends (annual numbers can hide seasonality or decline)
• Model the acquisition: purchase price, debt service, free cash flow to equity
• Estimate returns: can you achieve 25%+ IRR over 5-7 years with realistic assumptions?

Business quality assessment

• Customer retention and churn analysis
• competitive environment: how defensible is the business?
• Growth potential: organic levers and buy-and-build opportunity
• Management team: who stays post-acquisition? Do you need to hire?
• Technology and systems: how modern or legacy is the infrastructure?

Deal viability

• Is the asking price financeable? Can a bank/SBA underwrite this deal?
• Seller motivation: are they serious and ready to transact?
• Timeline: does the seller’s preferred timeline match yours?
• Deal-breakers: any red flags that can’t be mitigated?

Building your screening system

Tools

• CRM/spreadsheet: Track every opportunity with key data fields (source, industry, revenue, EBITDA, status, notes)
• Scoring rubric: 1-5 score on 8-10 criteria. Businesses scoring 35+ out of 50 get deep evaluation
• Deal memo template: One-page summary for promising opportunities (thesis fit, financials, key risks, next steps)

Cadence

• Weekly: Review all new opportunities from brokers, marketplaces, and outreach. Apply Tier 1 filters
• Bi-weekly: Deep evaluation sessions for Tier 3 candidates
• Monthly: Review pipeline metrics: opportunities screened, CIMs reviewed, seller meetings, LOIs submitted

Common screening mistakes

• Analysis paralysis: Spending 10 hours on every opportunity instead of screening ruthlessly. Use the tiered approach
• Falling for the story: A compelling CIM doesn’t mean good economics. Always check the numbers first
• Ignoring your thesis: “This isn’t in my target industry but looks interesting”, stay disciplined
• Not tracking metrics: If you can’t measure your funnel, you can’t improve it
• Screening too tightly: If you pass on everything, your criteria may be unrealistic. Revisit your target criteria

IESE’s 2024 International Search Fund Study notes that international searchers often face thinner deal flow than US-based peers, making disciplined screening even more critical , wasting time on a poor-fit opportunity has a higher opportunity cost when the pipeline is smaller.

Frequently asked questions

How many businesses do I need to screen to find one to acquire?

The typical search fund funnel starts with 500-2,000 identified businesses and narrows to 200-400 after Tier 1 filters, 50-100 CIM reviews, 15-30 deep evaluations, 5-15 seller meetings, 3-8 LOIs, and ultimately one closed acquisition. This process takes 12-24 months on average.

What are the most important screening criteria?

At Tier 1, focus on revenue minimum, EBITDA floor, target industry, geography, and a reasonable asking multiple. At Tier 2, dig into revenue trends, customer concentration, owner dependency, and margin consistency. At Tier 3, recalculate adjusted EBITDA from raw financials, model the deal, and assess management depth and competitive positioning.

Should I use a scoring rubric or go with intuition?

Use a scoring rubric. A structured 1-5 scale across 8-10 criteria removes emotional bias and enables consistent comparison between opportunities. Businesses scoring above your threshold (e.g., 35+ out of 50) advance to deep evaluation. This approach is especially important when multiple team members or investors are involved in screening decisions.
