Payment structures & deal architecture — the conceptual map of the entire module.

Most pieces in this topic deep-dive a single mechanism. This one zooms out. It exists because deal architecture is a system, not a stack of independent choices. A 70% cash deal interacts with the basket structure. The seller note's subordination interacts with the cross-default clause. The rollover dynamic interacts with the 2026 PE exit cycle. Sellers who navigate the module without the map end up making locally-optimal choices that combine into a globally-suboptimal deal.

§ 01 · The Clean Break — All-Cash & Net WireThe Pole of Maximum Certainty.

The All-Cash deal represents the Pole of Maximum Certainty — immediate transfer of 100% of the purchase price via wire transfer, eliminating all post-closing performance risk and credit exposure.

The Liquidity Discount: certainty is a purchased product. An All-Cash deal typically commands a multiple in the 1.5×–2.2× of revenue range, compared to the 2.5×–3.0×+ range for structures laden with earnouts and rollover. This discount is the insurance premium the buyer charges to assume 100% of future risk. Per the readiness model, the multiple expressed against Normalized EBITDA still maps to the canonical bands — the structural discount applies inside whatever band the agency qualifies for, not as a substitute for the band framework.

The Tax Spike: All-Cash triggers realization of the entire capital gain in a single tax year, potentially pushing the seller into the highest marginal brackets (Federal + NIIT + State).

Net Wire formula: Purchase Price − Existing Business Debt − Escrow Holdback ± Working Capital Adjustment. The Headline Price is never the amount wired.

§ 02 · Seller FinancingFrom sweetener to mezzanine debt.

In the 2025–2026 market, Seller Notes have evolved from passive "good faith" gestures into high-risk subordinated debt instruments bridging capital gaps. Mezzanine pricing: with the Prime Rate hovering between 7.5% and 8.5%, seller notes should yield 7–9% to reflect their subordinated status. Softening rates in 2026 are nudging this toward 5–8%, but the Treasury + 300bps floor still applies.

The Subordination Trap: seller notes are almost always junior to senior bank debt. If the buyer trips a bank covenant (DSCR drops below 1.25×), the bank can freeze note payments indefinitely (Payment Blockage).

Security architecture: Stock Pledge Agreement + UCC-1 Financing Statement to secure the note against agency equity. SBA bifurcation: for deals under $5M using SBA 7(a) financing, structure as Standby Note (max 5%, no payments) + Servicing Note (balance, monthly P&I).

§ 03 · EarnoutsThe performance-contingent gamble.

Earnouts bridge the valuation gap but introduce the highest risk profile, with a base collection probability of approximately 50%.

Metric selection: sellers should prioritize Revenue metrics (harder to manipulate) over EBITDA. If EBITDA is used, it must be Pro Forma Adjusted to exclude buyer-imposed corporate overhead (Shadow Accounting).

The Gallagher precedent: recent case law (Gallagher v. Agiato) dictates that earnouts must be legally decoupled from employment to avoid IRS recharacterization as ordinary income.

Covenant architecture: vague "commercially reasonable efforts" clauses are unenforceable. Sellers require Specific Negative Covenants — for example, "Buyer shall not reduce marketing spend below $150K."

§ 04 · Rollover EquityThe Second Bite.

Rollover equity involves reinvesting 20–40% of proceeds into the buyer's platform. The Multiple Arbitrage potential is meaningful — rolling at the upper edge of the market band (8–10×) into a platform exiting in or above the competitive band (10–12×) creates real wealth gain. The Minority Trap risks are equally meaningful.

Governance and liquidity: Tag-Along Rights (preventing the Stranded Minority scenario) and a Put Option (creating a guaranteed liquidity window at Year 5–7) are non-negotiable protections.

Capital stack risks: if Debt/EBITDA exceeds 6.0×, the equity is at high risk of Debt Wipeout where senior lenders consume all exit value.

Tax structure: S-Corp sellers must utilize an F-Reorganization to defer taxes on the rollover. A taxable rollover results in an immediate ~25% tax hit on illiquid stock.

§ 05 · Defensive ArchitectureThe protections that survive the LOI.

Holdbacks & Escrow: indemnification caps and baskets (Tipping vs. True Deductible), RWI optimization, survival periods (12–18 months standard).

Legal provisions: Set-Off Rights (Unrestricted vs. Arbitrated), Cross-Default Clauses, Anti-Sandbagging Protections. These are treated in depth across the Risk Allocation & Indemnification cluster and the earnout-specific defenses in the Earnout Defense & Protective Provisions cluster.

§ 06 · 2026 Market ContextThe macro frame.

Return of Cash: shift to 80–90% upfront as senior-debt costs decline near 6%. PE Exit Cycle Acceleration: the 2025–2027 window for 2019–2021 fund vintages, driving rollover consolidation into TopCo. Rate Environment Impact: softening seller-note rates (5–8% range), but security demands (Stock Pledge, UCC-1) remain non-negotiable.

§ 07 · The map's purposeSystem over component.

Every decision in this module has a counterpart somewhere else in the module. The All-Cash discount maps to the band the agency qualifies for. The seller-note rate maps to the macro rate environment. The earnout collection probability maps to the indemnification holdback. The rollover percentage maps to the PE exit cycle. Sellers who see these as independent levers are negotiating from the wrong altitude. The map is the right altitude.
