The first, anchor acquisition in a buy-and-build strategy — a company bought to serve as the <em>base</em> onto which smaller add-ons are later bolted.
A pre-arranged debt package the sell-side advisor offers to all bidders for a target — financing <em>stapled</em> to the deal so buyers can move faster.
A contract clause letting a buyer walk away if the target suffers a serious, lasting deterioration between signing and closing — the deal's <em>escape hatch</em>.
A smaller acquisition added to an existing platform company — bought to be <em>integrated</em> rather than run standalone, expanding the platform's scale or reach.
Acquiring all the shares of a listed company and delisting it — moving the business off public markets into <em>private</em> ownership.
Money set aside with a neutral third party at closing, released later once conditions are met — security for the buyer's <em>indemnity</em> claims.
