Asset vs. stock purchase — the default and the exceptions.

The asset-versus-stock decision is the most consequential structural choice in a deal, and for most agency acquisitions it's not close: the asset purchase wins because it lets the buyer take the book and leave the seller's history behind. The interesting work isn't defending the default — it's recognizing the specific situations where the default breaks, because forcing an asset deal when a stock deal is required can cost the buyer the very appointment that made the agency worth buying.

§ 01 · Why the asset purchase is the defaultAnd what it leaves behind.

The asset purchase is the default for sub-$5M agency deals because it strips out successor liability — the buyer takes a defined list of assets and only the liabilities it affirmatively assumes, so recreating that protection inside a stock deal usually costs more in escrow, reps, and baskets than simply leaving the entity behind. There are four equitable exceptions where a court can attach liability anyway (explicit assumption, the de-facto-merger doctrine, the mere-continuation doctrine, and product-line continuity), but outside those a buyer's exposure is limited to what it chooses to assume. Three concrete liabilities the asset structure leaves with the seller make the case vivid: pending E&O claims and threatened litigation, pre-closing tax exposure including payroll, and employment claims (wage-and-hour, classification, and the like). Those are exactly the liabilities that can swamp a small agency deal, which is why the asset structure is the starting point.

§ 02 · When a stock purchase is justifiedThe three exceptions.

The exceptions all share a logic: something valuable is bound to the entity and would be lost in an asset transfer. The carrier-appointment case is the most common in agency deals — a single appointment that can't be reassigned and carries more than ~20% of revenue can force a stock structure, because the alternative is re-applying for the appointment post-close, a 30–90 day cycle for new appointments (and de-novo qualification rather than consent for some specialty or older direct-writer agreements). Entity-bound licenses work the same way: an MGA authority or surplus-lines authorization that attaches to the entity rather than the assets. And tax attributes — net operating losses, depreciation positions, though subject to the usual utilization limits — can be worth preserving. When the structure genuinely can't move off stock, the buyer's mitigation package is a larger escrow, longer survival periods on the key reps, and explicit carve-out indemnification for known liability categories.

§ 03 · The tax bridgeReconciling the seller's preference.

Sellers often prefer a stock sale for their own tax reasons, which sets up a structural tug-of-war the buyer can usually win without giving up the asset structure. The tool is the tax-bridge gross-up: a 5%–8% price increase typically closes the seller's after-tax difference between a stock and an asset deal, so the buyer pays a modest premium and keeps the structural protection that's worth far more than the premium. For an S-corporation seller, a more elegant path exists — a tax-free entity conversion before closing (an "F-reorganization") that gives the seller capital-gains treatment while letting the buyer take the asset structure; the mechanics are non-trivial and the tax-counsel cost is usually justified only on deals above $2M. Either way, the principle holds: the buyer rarely needs to concede the structure to satisfy the seller's tax goal — they need to price the gross-up, and engage tax counsel rather than improvising. The drafting of the agreement that implements all this is in asset sale vs. stock sale.

§ 04 · What transfers, and when to decideThe defined lists and the sequencing.

The two structures move different things, and knowing the lists prevents a buyer from assuming an asset will come along when it won't. An asset purchase transfers a defined list: the book of business (renewal rights and client relationships), the brand and trade names, the management-system data, furniture and equipment, the assignable carrier appointments, and the intellectual property and marketing assets — while the corporate entity and the retained liabilities stay behind by default. A stock purchase transfers the equity, and everything rides with the entity: every contract, license, lawsuit, tax position, and employment relationship continues unchanged. The most important procedural rule is to settle the structure at the indication-of-interest or early-LOI stage, because re-doing the structure after the price is locked unwinds the negotiation — the carrier-appointment list, the lines written, the licensing footprint, and the entity history are all knowable before the LOI, so the decision can be made early and held. The carrier-consent dimension that often drives this choice is in carrier change-of-control risk.
