The Add-Back Audit: How to Stress-Test Seller Adjustments Before You Underwrite

Before you underwrite a single turn of leverage, every seller adjustment in that EBITDA bridge deserves a rigorous line-by-line audit. This episode lays out a practical framework for stress-testing add-backs and arriving at a purchase-price-ready earnings figure that's yours — not the seller's.

Show Notes

Seller-prepared EBITDA bridges can look compelling on the surface, but a stack of add-backs — each with a reasonable-sounding label — can inflate adjusted earnings by a third or more before a buyer ever touches a model. This episode of PrivateEquityInvestor.com walks through a disciplined, step-by-step framework for auditing every seller adjustment before underwriting begins, so deal teams enter price negotiations anchored to their own defensible earnings figure rather than the seller's.

As mid-market deal competition intensifies — and as explored in the site's recent analysis of rising EBITDA thresholds in mid-market PE — precision in the adjusted EBITDA build has never mattered more. The episode covers:

• The three-bucket sorting method: Classifying every adjustment as recurring by nature, genuinely non-recurring, or ambiguous — and why most of the real work lives in that third bucket.
• Owner compensation normalization: Why a market-rate replacement cost is never zero, and how to anchor the add-back to the actual cost of filling the role post-close rather than accepting the seller's full draw.
• The documentation test for one-time items: How to distinguish a truly closed legal settlement from a cyclical capital expenditure pattern that belongs in normalized maintenance capex, not in the EBITDA bridge.
• Creative adjustments in the ambiguous bucket: Using the example of a family-member consulting arrangement to illustrate why buyers must ask what function was performed, who performs it post-close, and at what cost.
• The symmetry check on revenue-linked add-backs: If a seller normalizes away a cost disruption, the revenue lost during that same period must be examined — add-backs should reflect a true steady-state run rate on both sides of the P&L.
• Translating the audit into a negotiating position: Building a buyer-owned adjusted EBITDA figure, quantifying the add-back haircut, and knowing which items to escalate to a quality-of-earnings provider for forensic review.

The episode also touches on how a preliminary add-back audit functions as a triage before engaging a QoE team — helping buyers direct diligence resources toward the adjustments that carry the most valuation risk. Teams looking to sharpen their pre-LOI process can pair this framework with the Private Equity Deal Evaluation Checklist to ensure nothing falls through the cracks.
