Active deal execution — valuation, DD, negotiation.

Active deal execution is the work that begins once a target has been identified and runs through definitive-agreement signing. The buyer who has done the pre-acquisition planning work — strategy, profile, sourcing — arrives at this stage with leverage that the buyer who skipped the planning never has. Three sequential disciplines structure the middle phase: valuation, due diligence, and negotiation. Each builds on the prior; each fails predictably when the prior was sloppy.

Normalized EBITDA, structure-aware.

The valuation work that supports an LOI is not the same as the post-LOI Quality of Earnings exercise. It is a defensible pre-diligence pricing model based on the seller's CIM, basic public-data triangulation, and the buyer's own benchmark intelligence. Two principles govern.

First, anchor on normalized EBITDA, not the seller's adjusted EBITDA. The seller's adjusted number is an aspirational anchor that builds in every favorable add-back. The buyer's normalized number includes only the add-backs the buyer can defend with reference to source documents the seller has not yet produced. The delta between adjusted and normalized — typically 15–35% — is the pricing range the LOI should bracket.

Second, price the structure, not the headline multiple. A 6× all-cash offer and a 7× offer with a 30% earnout against post-close performance targets are not the same deal. The buyer's actual cost depends on probability-weighted earnout realization under realistic operating scenarios — not the headline number.

Structure-aware pricing protects against winner's curse. The buyer who knows the strategy and the capital envelope walks away from the wrong deal at the LOI stage, not at the closing stage where walk-away costs are paid in legal fees and reputation.

Financial, HR, legal, operational, customer.

Once the LOI is signed, due diligence opens. The Five-Pillar framework structures the buyer's verification of the seller's representations. Each pillar has its own deep-dive cluster; the framing here is how they integrate.

• Financial DD. The forensic-investigation layer. Quality of earnings, premium trust audit, normalized EBITDA verification, balance sheet forensics, revenue concentration. The pillar that turns the seller's narrative into a defensible model. Covered in depth at financial due diligence.
• HR DD. Producer compensation architecture, restrictive covenants, key-person dependency, talent retention. The pillar that determines whether the post-close talent base actually stays. Covered at HR due diligence.
• Legal & regulatory DD. Corporate governance, purchase-agreement architecture, regulatory and compliance posture, risk and liability mapping. The pillar that surfaces what the buyer is actually inheriting in terms of contingent obligations. Covered at legal and regulatory due diligence.
• Operational DD. AMS health, workflow productivity, key-person risk, reputation. The pillar that predicts integration friction and post-close productivity. Covered at operational due diligence.
• Customer DD. Book quality, retention, concentration, defensibility. The pillar that validates the revenue line the entire pro-forma rests on. Covered at customer due diligence.

The five pillars are not optional; they are not sequential. They run in parallel during the diligence window and integrate findings into a single risk register that drives the buyer's retrade math (ethical retrade only — material discovery, not negotiation gamesmanship), the indemnification provisions in the purchase agreement, and the earnout structure if one is used.

Cash, note, earnout, rollover.

The negotiation phase converts DD findings into deal terms. Four structural elements dominate the discussion.

Rollover equity is the fourth element — the seller retains a minority equity position in the combined entity. This is most common in private-equity-backed deals where the rollover aligns the seller's post-close behavior with the buyer's exit thesis. For independent buyers, rollover is unusual but can be the right tool when the seller is exiting partial and contributing operational continuity.

The definitive agreement — APA for asset deals, SPA for stock deals — papers the risk allocation through reps and warranties, indemnification baskets and caps, survival periods, and escrow holdbacks. The proper construction of these provisions is the legal-architecture work — covered at legal architecture for buyers — that converts diligence findings into enforceable buyer protections.

The cluster's three workstreams pair with the broader pillar — acquisition process navigation — and produce the leverage that determines whether the buyer's deal economics survive the closing process and the post-close integration that follows.
