Asset purchase vs share purchase in startup M&A

A buyer can acquire a startup in two basic ways. In a share purchase (or merger), it buys the company itself, with everything inside it. In an asset purchase, it buys selected assets such as code, patents, domain names and customer contracts, and leaves the company and anything it does not want behind.

Share purchases and mergers

Buying the shares transfers the whole business in one step: employees, contracts, licences, intellectual property and also all liabilities, known or unknown. That is simpler for continuity, because contracts usually stay in place unless they contain change-of-control clauses. Buyers protect themselves through due diligence, warranties, indemnities and an escrow.

Most venture-backed startups are sold this way, often through a merger with a subsidiary of the buyer, because it lets every shareholder be paid according to the company's charter.

Asset purchases

An asset purchase lets the buyer pick what it wants and leave liabilities behind. It is common when a startup is struggling, when it has unresolved disputes or debts, or when the buyer wants only the technology or the team. Contracts generally have to be assigned one by one, which needs counterparties' consent, and employees are rehired by the buyer rather than transferred automatically (rules differ by country; in the UK and EU, employment protections often move staff with the business).

The money goes to the company, not directly to shareholders. The company then pays its creditors and distributes what is left, which can take time and may leave little for common shareholders.

Employee stock options are affected too. In a share sale the buyer typically assumes, converts or cashes out options under the plan's terms. In an asset sale the options stay with the old company, so staff usually rely on new grants from the buyer instead.

Taxes and price

Tax treatment often decides the structure. In many countries buyers prefer asset deals because they can depreciate the purchase price, while sellers prefer share deals because the gain is taxed once, at the shareholder level. The price usually moves to reflect who carries more risk and who gets the better tax result.

Hybrid structures

Real deals often mix the two. A buyer may acquire the shares of a subsidiary that holds only the business it wants, a carve-out. It may license the technology and hire the team while the original company stays in place. Or it may buy shares but exclude a particular product line or liability by moving it out of the company before closing. Each version tries to give the buyer what it wants without taking on what it fears.

Which is better for founders?

For a healthy startup with clean records, a share sale or merger is usually simpler and gets money to shareholders faster, with less paperwork. An asset sale can be the only realistic option for a company with debts, disputes or a buyer who only wants part of the business. In that case founders should look closely at what is left behind: who pays outstanding obligations, how the company will be wound down and how long that will take.
