Most lower-middle-market transactions do not close at the letter-of-intent number. The structural gap between LOI and closing value is not random. It reflects a persistent mismatch between the buyer underwriting model that prices the offer and the founder preparation that supports the financial statements. This paper introduces the Buyer Lane Preparation Map, a framework distinguishing how preparation requirements diverge across the five active buyer archetypes in the lower-middle-market segment ($2M to $25M EBITDA): the private equity add-on, the private equity platform, the strategic acquirer, the family office, and the search fund or independent sponsor.
Each archetype underwrites against a different model. The private equity add-on operates under a senior-debt service constraint that ceilings price at multiples narrower than headline data suggests. The strategic acquirer prices to synergy realism. The family office prices to operational continuity and tax structure. The search fund operates under SBA-backed lending criteria with specific addback rules. These models diverge most materially in their treatment of customer concentration, working-capital normalization, owner compensation, and management dependency.
Drawing on transaction data from GF Data Resources, SRS Acquiom, Pepperdine Private Capital Markets, Capstone Partners, Cherry Bekaert, and Bain & Company, this paper documents the empirical patterns by which buyer archetype determines post-LOI value compression. The named finding is that the post-LOI gap is forecastable in advance of buyer engagement when the founder's likely buyer set is mapped and preparation is calibrated against the underwriting models specific to that set. The map is what makes the gap closeable.
The five active archetypes operating in the $2M–$25M EBITDA segment, their relative deal share, and the conditions under which each is the marginal buyer.
How each archetype prices the same financials differently: senior-debt service for the PE add-on, synergy realism for the strategic, operational continuity for the family office, SBA addback rules for the search fund.
The empirical magnitude of the post-LOI compression by archetype, and why the gap is structural rather than negotiated.
The framework itself: how to map a founder's likely buyer set in advance and calibrate preparation against the underwriting models specific to that set.
Pattern-level vignettes drawn from the underlying data illustrating customer-concentration treatment, working-capital normalization, owner compensation, and management dependency across archetypes.
The operational consequence: how a forecasted buyer set, surfaced upstream, becomes the input that determines what preparation actually changes outcomes.
This paper builds on Cordis Institute Working Paper WP-001, The Preparation Gap in Early 2026, which documented the aggregate post-LOI gap. WP-002 disaggregates that gap across active buyer archetypes.
