Retrades are accelerating in agency M&A for three structural reasons — abundant capital chasing scarce deals pushes LOI prices to the top of the market, longer diligence windows (30 days stretching to 60–90) give more time to find things, and professional-services finders whose reputations depend on finding something. So a seller who wants to hold the price they signed needs a defense, and the defense starts with a framework that separates the findings that deserve a price change from the ones that are just leverage.
§ 01 · The three-test frameworkLegitimate or manufactured.
| Test | The question |
|---|---|
| Materiality | Is the finding large enough to warrant a price change? |
| Novelty | Was it genuinely new, or reasonably discoverable pre-LOI? |
| Documentability | Is it quantified to a specific dollar with specific evidence? |
Three tests applied to any retrade demand separate the real from the manufactured. Materiality asks whether the finding is large enough to warrant a price change at all. Novelty asks whether it was genuinely new information or something reasonably discoverable before the LOI — because a buyer re-litigating something they could have found pre-LOI is reaching for leverage, not surfacing a surprise. And documentability asks whether it's quantified to a specific dollar number with specific evidence, rather than a vague assertion. A legitimate retrade passes all three; a leverage play fails at least one. Applying the tests turns a retrade demand from an emotional moment into an analytical one, which is exactly the posture a seller needs to hold the price — and the pre-LOI preparation that defeats the novelty argument is in pre-LOI data-room population.
§ 02 · The materiality scaleAdjustment, retrade, or walk.
Materiality calibrates the response. Under 5% of adjusted EBITDA impact is a closing-table adjustment, not a retrade — a 2% EBITDA adjustment on $500K of EBITDA is $10K, a rounding item. 5%–15% is legitimate retrade territory. And over 15% means the LOI was priced on bad information, where either party may rightly walk. The scale keeps small findings from being inflated into price reductions, and large ones from being waved through.
The materiality scale gives the three-test framework its teeth, because "material" is otherwise in the eye of the beholder. An impact under 5% of adjusted EBITDA is a closing-table adjustment — the kind of true-up that happens in any deal — and dressing it up as a retrade is a leverage play; a 2% adjustment on $500K of EBITDA is $10K, which doesn't move a deal. An impact of 5%–15% is genuine retrade territory, where a price conversation is warranted. And an impact over 15% means the LOI was priced on bad information in the first place, at which point either party may rightly walk — it's not a negotiation tactic, it's a sign the deal premise was wrong. A seller who knows the scale can respond to a retrade demand by sizing the finding and placing it on the scale, which immediately reframes a leverage play as the rounding item it is.
§ 03 · The five-defense playbookMaking the price hard to move.
The best retrade defense is built before the retrade, in a five-part playbook. Pre-LOI data-room population defeats the novelty argument — a buyer can't claim a "surprise" about something that was in the data room at the LOI. A seller-commissioned quality-of-earnings report ($25K–$60K depending on agency size) anchors the financials independently, with an ROI on a single retrade defense often 10–20× its cost. An objective valuation anchor — a source-verified valuation — gives both sides a number neither commissioned for advantage. Structural LOI provisions (below) raise the bar for any retrade. And active competitive tension — a credible alternate buyer — gives the seller a real walk-away. Against this playbook, the four common manufactured retrade patterns lose their force: the late-breaking add-back reversal (re-litigating pre-LOI-accepted add-backs), the accumulated small-item retrade (15 small findings summed into a 7%–10% adjustment), the "market has changed" claim (almost always manufactured — the LOI was signed at a point in time), and the trust-position or licensing "surprise" (real deficits justify real adjustments, but minor timing issues don't justify a 10% retrade). The QoE that anchors this is in the seller-commissioned QoE.
§ 04 · LOI provisions and the walk-numberThe structural and final defenses.
Two more defenses make the playbook durable. Four structural LOI provisions, negotiated up front, raise the bar for any retrade: materiality thresholds (no retrade below a stated dollar or percentage), time limits on new findings (no retrade based on pre-LOI-discoverable information), specific-performance deposits (forfeited if the buyer walks outside a defined materiality), and good-faith diligence obligations (a defined scope and window). Alongside them, backup-buyer discipline — maintaining at least a secondary buyer through LOI signing, ideally through exclusivity expiration — provides the leverage that holds price even though the credible walk-away rarely needs to be exercised. When a retrade does come, the response sequence is disciplined: don't respond in anger or in the moment, force specificity (each finding, its dollar impact, its evidence), apply the three tests, separate legitimate findings from leverage plays, reference the objective anchors, and know your walk-number. That walk-number — a price defined before the process below which the deal is worse than no deal — is the final defense, and the discipline is to use it when the math justifies, because sellers who walk when walking is warranted find more deals appear, often at better terms. The book-ownership protections that pair with this on the legal side are in producer non-piracy and book ownership.
