EBITDA Adjustments Explained for LMM Deals

Lower middle market businesses are typically owner-operated, and owner-operated businesses routinely commingle personal and business expenses in ways that distort the reported P&L. A founder who runs personal automobile expenses through the company, pays family members above-market salaries, or takes discretionary bonuses in lieu of dividends is creating a GAAP EBITDA figure that does not reflect the true earnings power of the business under professional ownership. Adjustments correct for this distortion.

The purpose of EBITDA adjustments is to normalize the income statement to reflect what a hypothetical market-rate management team would spend to operate the business at its current scale. This is an inherently forward-looking exercise that requires judgment about what 'normal' operating costs look like, and that judgment is where significant variation—and negotiation—occurs between buyers and sellers.

The most clearly legitimate addbacks fall into three categories. First, above-market owner compensation: if the selling founder is paying themselves $800,000 per year and a replacement CEO would cost $350,000, the $450,000 difference is a legitimate adjustment. The key is that the replacement cost must be specific and verifiable, not aspirationally low. Second, non-recurring expenses: litigation settlement costs, one-time restructuring charges, or a specific facility write-off are legitimate addbacks if they are genuinely non-recurring and not indicative of a recurring operational pattern. Third, personal expenses charged to the business: this is common in LMM and generally straightforward if the expenses can be specifically identified.

A more contested category is the adjustment for future cost savings—for example, planned technology upgrades that will reduce headcount, or real estate consolidation that will reduce occupancy costs. These adjustments require the buyer to accept execution risk on synergies that have not yet been realized. Legitimate cases exist, but they should be discounted for certainty and treated separately from operational EBITDA in the returns model.

Several patterns in addback schedules should trigger heightened scrutiny. Recurring items labeled as non-recurring: if a business has had 'one-time' IT implementation costs in three of the last four fiscal years, those costs are not one-time—they reflect an ongoing technology refresh cycle. Revenue-side adjustments: addbacks that adjust reported revenue upward rather than operating costs downward are unusual and should be examined carefully. The most common form is a revenue normalization for a contract that was delayed or underperformed, projected to recur at full run-rate.

Also watch for adjustment schedules that have grown significantly in the most recent period. A business that reported $1.2M in EBITDA addbacks two years ago and is now claiming $3.1M in addbacks is either being managed much more aggressively for sale or has genuinely changed its operating structure—and determining which is true is a critical diligence question. Request a vintage analysis of the adjustments: how much of the current adjustment pool appeared for the first time in the last twelve months?

For transactions above $5M in EBITDA, a quality of earnings (QoE) report commissioned by the buyer's financial advisors is standard practice and should be non-negotiable. The QoE report serves multiple functions: it validates the adjustment methodology, identifies items the seller's advisors have missed or obscured, and provides a defensible basis for the financial assumptions in the buyer's model.

When reviewing a QoE report, focus particularly on the difference between the seller's claimed adjusted EBITDA and the QoE-adjusted figure. A gap of 5–10% is common and manageable. A gap exceeding 15% often indicates either aggressive seller accounting or a fundamental disagreement about what constitutes a legitimate addback—and that disagreement needs to be resolved before LOI, not after.

After completing the addback analysis, build your returns model on two EBITDA scenarios: seller-adjusted and QoE-adjusted. The spread between these two figures represents the EBITDA-at-risk if the buy-side's more conservative view prevails. If your target returns require the seller's EBITDA figure and are impaired under the QoE-adjusted figure, that tells you the deal is only attractive if you accept the seller's accounting—a vulnerable position to be in.

Conservative underwriting means anchoring to a defensible EBITDA figure and stress-testing it further. Apply a 10–15% haircut to your conservative EBITDA and check whether the deal still works. If the only scenario in which you hit your return target requires every addback to be real and every run-rate projection to materialize, the risk profile of the deal is significantly higher than the headline multiple implies.
