Indication of Interest (IOI)

What is Indication of Interest (IOI)?

An Indication of Interest (IOI) is a non-binding statement made by a potential investor or buyer to express preliminary interest in a transaction. It’s often used in IPOs, mergers & acquisitions, or fundraising rounds to signal that a party may want to participate—without making a formal commitment.

Purpose of an IOI

An IOI helps to:

  • Gauge market demand before finalizing a deal.
  • Show that the investor or acquirer is seriously considering the opportunity.
  • Start discussions and move toward deeper negotiations or due diligence.
  • Give the seller or issuer a sense of valuation and deal structure expectations.

When is an IOI Used?

  • Mergers & Acquisitions (M&A): A buyer sends an IOI before submitting a Letter of Intent (LOI).
  • Initial Public Offerings (IPO): Institutional investors submit IOIs to show demand for shares before pricing.
  • Private Equity/Venture Capital: Firms express interest in investing in a startup or company.
  • Real Estate or Asset Sales: Used to pre-qualify buyers for large transactions.

What an IOI Typically Includes?

  • Name of the interested party
  • Target company or asset
  • Indicative purchase price or investment amount
  • Deal structure (e.g., cash, stock)
  • Proposed timeline for due diligence and closing
  • Conditions for moving forward
  • Statement that the IOI is non-binding
