What is an indication of interest (IOI)?

Definition

Indication of interest (IOI): A short, non-binding first-round offer in which a bidder states an approximate value range and its main assumptions, used by the seller to decide who moves forward.

How it works in a data room

At the IOI stage most bidders have seen only the information memorandum and a limited set of supporting documents. Some sellers collect IOIs by email; others ask bidders to upload them into a private folder in the room, visible only to the seller team, with a timestamp that proves the deadline was met. The submission usually covers a valuation range, financing sources, required approvals, the diligence still needed and the expected timetable.

Why it matters in a deal

IOIs are how a seller narrows a crowded field without granting everyone deep access. Comparing ranges side by side, along with each bidder’s financing certainty and reading activity in the room, tells the adviser which parties deserve second-round attention. For the bidder, an IOI that is too low gets it dropped, while one that is too high may set expectations it cannot later meet. The private equity guide covers how sponsors typically approach this step.

Example

In a controlled auction for a Canadian specialty chemicals company, eleven bidders submit IOIs by a Friday deadline through upload links in the room. The adviser charts the ranges, notes that two rely on financing not yet arranged, and invites five to the second round. Those five receive access to the full room on Monday morning. The Canada guide covers the local privacy law that applies once employee files are opened.
