Investment banks rank acquirers by scoring every name on the long list against the same five criteria: strategic fit, mandate match, ability to pay, acquisition cadence, and access. The weighted score sorts buyers into Tier 1, 2, and 3. Tier 1 gets a call from the senior banker, Tier 2 gets the teaser, and Tier 3 waits. The ranking is redone after teaser responses and again after management meetings.
Decide what the ranking is for
The first ranking decides who gets a phone call and who gets an email. It does not predict who bids highest. A team that treats the score as a closing forecast wastes two weeks defending a 4.1 against a 3.9.
Settle seller restrictions before you score anyone. A competitor the owner refuses to meet is a Tier 3, whatever the fit. Write the restriction on the list so a second analyst does not add the name back.
Do not rank by size or name recognition. The familiar national brand often has no mandate for a $6 million EBITDA business. The regional operator two states over often does.
Score every buyer on the same five criteria
Build the long list first. Our guide to finding strategic acquirers covers where the names come from. Then score each name from 1 to 5 in every column, multiply by the weight, and sum.
Acquirer scoring worksheet
Column Weight What a 5 looks like Strategic fit 30% Seller adds a customer, capability, or region the buyer has said it wants Mandate match 25% Size, sector, and platform-or-add-on role match the buyer's current criteria Ability to pay 20% Cash, committed fund, or credit line covers the expected price Acquisition cadence 15% Two or more closed deals in the last 24 months Access 10% Named decision maker, warm path, and no seller restriction Tier 1: weighted score of 4.0 or higher. Tier 2: 3.0 to 3.9. Tier 3: below 3.0, or any seller restriction.
Rule: an "unknown" in a column weighted 20% or more sends the buyer to the research queue before it gets a tier.
Every score needs a source in the next column. For a public strategic, the acquisition strategy and cash position sit in the 10-K on SEC EDGAR. For a sponsor, the fund vintage, dry powder, and add-on history sit in PitchBook. A press release about "growth through acquisition" with no closed deals behind it scores a 2 on cadence, not a 4.
Cadence carries weight because it predicts behavior. Bain's annual M&A report has found for years that frequent acquirers outperform occasional ones. A buyer that closes two deals a year has a process, a board that says yes, and people who return calls.
Sort the tiers into three queues
Tier 1 is ready for approved outreach. The managing director calls the decision maker before the teaser goes out. In our experience this is 15 to 25 names in a targeted process.
Tier 2 is the teaser email list, usually 40 to 80 names. The fit is plausible. A response will tell you more than another week of desk research.
Tier 3 is hold or exclude. Write the reason next to each name: "seller restriction", "size mandate under $3 million EBITDA", "no deals since 2022". A reason stops the name from returning when someone finds it again.
Suppose a $6 million EBITDA HVAC services company in Ohio. A national roll-up scores 5 on fit and 5 on cadence, but its add-on floor is unknown. It goes to research, not Tier 1. A sponsor-backed regional platform scores 4 across the board and has a named VP of corporate development. That is your first call.
Keep a buyer log and re-rank at two checkpoints
The buyer log is the working record for the process. One row per buyer: tier, contact, date teaser sent, NDA date, CIM date, response, reason for a pass, next step, owner. Update it the same day something happens.
Re-rank after teaser responses, about ten days after the send. A Tier 2 that signs the NDA in 24 hours moves to Tier 1. A Tier 1 that goes silent for two weeks moves down, and the banker makes one more call before it drops. Buyers filter fast, and how buyers decide which deals to engage explains why silence is the normal response, not a pass.
Re-rank again after management meetings. Record what each buyer asked about and which mandate it named. A pass on timing stays a timing pass. Do not turn it into a permanent sector exclusion. A data room request is interest, not committed funding, so leave the ability-to-pay score alone until you see proof.
Where PrivSource fits: AI Buyer List returns buyer candidates with a written fit reason for each one, which fills the strategic fit column and its source on day one. It does not confirm a current mandate or a buyer's readiness. The advisor still checks those two columns, scores the rest, and owns the tiers.
