In a stock sale (or membership-interest sale for an LLC), the buyer purchases the ownership equity of the company itself, acquiring the entire legal entity, all its assets, contracts, licenses, and liabilities, in one transaction. The company continues unchanged; only its owner changes.
When a stock sale makes sense
- Non-transferable licenses or permits tied to the entity (e.g. certain liquor, franchise, or regulatory licenses)
- Long-term customer contracts that can't be reassigned
- Seller tax preference, capital-gains treatment on the whole gain
Trade-off: the buyer assumes hidden liabilities, so diligence and strong indemnities matter far more than in an asset sale.
Why it matters when buying a business
If the value of a business lives in contracts or licenses that die on transfer, a stock sale may be the only way to keep it whole. But you inherit everything, so you'll want thorough QoE, tax, and legal diligence and robust seller representations. Weigh it against the cleaner asset sale before you commit.
