Glossary term

Letter of Intent (LOI)

A letter of intent, or LOI, is the preliminary deal document that outlines proposed valuation, structure, exclusivity, and major commercial terms before definitive agreements are signed. In M&A, the LOI usually marks the transition from broad target screening into a more formal diligence process.

Quick take

The LOI is where early conviction turns into a structured deal process.

Why it matters

The LOI sets the pace, scope, and leverage dynamics of the next phase, which is why pre-LOI diligence and issue framing matter before exclusivity begins.
