Valuation Mistakes in Lower Middle Market Deals

The most common valuation mistake in LMM transactions is paying a growth premium for a business that has had one or two exceptional years. A business that grew revenue 35% in year one and 28% in year two attracts significant buyer interest and commands a growth premium in the multiple. But if years three through five show 8–12% growth as the initial growth catalyst normalizes, the buyer who paid a 9x multiple on year-two trailing EBITDA has significantly overpaid relative to the business's long-run earnings trajectory.

The discipline is to distinguish between growth that reflects durable competitive positioning—expanding into new markets, gaining share from a structurally weaker competitor, benefiting from a secular industry trend—versus growth that reflects a transient event—a single large customer win, a beneficial macro environment, a temporary supply-chain disruption that shifted business toward them. The former justifies a premium; the latter does not.

Valuation analyses routinely model management transition costs as a line item in the acquisition expense budget—legal, advisory, and recruiting fees for a replacement CEO. What they frequently fail to model is the performance impact of that transition: the revenue that may be disrupted as customer relationships adjust to new ownership, the operational efficiency loss while a new leader learns the business, and the time-to-competence curve for a replacement executive who needs six to twelve months to reach full effectiveness.

A more accurate valuation model includes a management transition period of twelve to eighteen months during which EBITDA margins are modeled at 80–90% of historical levels, revenue growth is modeled conservatively, and management-related expenses are elevated. The cumulative EBITDA impact of this transition period can easily exceed $500,000 to $1M on a $2–3M EBITDA business, which represents a material adjustment to the effective acquisition cost.

LMM buyers frequently evaluate transactions at or near the peak of a sector cycle without adequately modeling what performance looks like through a full cycle. Industrial services businesses, commercial construction-adjacent companies, and consumer-facing businesses all exhibit meaningful cyclicality that may not be visible in a three-year historical window if the evaluation period spans only the expansion phase.

Request ten-year historical financial data where available, and conduct peer research on how comparable businesses performed through the 2008–2009 recession and the 2020 pandemic disruption. These two stress periods provide different types of stress—one demand-driven, one supply-chain and operational—and together offer a reasonable picture of how the business's cost structure and customer relationships perform under adverse conditions.

A particularly insidious valuation mistake is anchoring to the seller's adjusted EBITDA figure as the baseline for negotiation. Once a seller's advisory team presents an adjusted EBITDA of $3.2M and a proposed 7x multiple, the negotiation naturally gravitates around that reference point—buyers push back to 6.5x or 6.0x while implicitly accepting the $3.2M base. The more productive approach is to establish your own independent EBITDA estimate, derived from a conservative reading of the financial statements, and negotiate from that baseline.

If your independent EBITDA estimate is $2.7M rather than the seller's $3.2M, a 6.5x multiple on your figure ($17.6M) represents a more attractive entry point than a 6.0x multiple on the seller's figure ($19.2M)—but you will only arrive at this conclusion if you resist the anchor and do the independent work.
