Indication of Interest (IOI)
A non-binding preliminary offer from a prospective buyer after reviewing the CIM — expressing interest, preliminary valuation range, and proposed deal structure to earn a place in the next round of the sale process.
Full Definition
The IOI is a gatekeeper document in an auction process. After receiving the CIM and doing preliminary analysis, a prospective buyer submits an IOI to signal serious interest and begin the deeper dialogue. Based on IOIs received, the seller's banker decides which buyers advance to management meetings and eventually LOIs. Unlike an LOI, the IOI is preliminary and low-commitment — typically 1-3 pages.
How it actually works: A typical IOI includes: (1) preliminary valuation range (e.g., "$18-22M enterprise value"); (2) proposed deal structure (cash, stock, earnout, rollover); (3) anticipated financing sources (equity sources, debt lenders); (4) key assumptions underlying the valuation; (5) timeline to LOI and closing; (6) required conditions (e.g., "subject to satisfactory management meetings"); (7) any material open questions. IOIs are non-binding — buyers can walk away with no consequences.
From the seller's perspective, IOIs serve three functions: (1) price discovery — what range does the market think this business is worth?; (2) buyer qualification — which buyers are serious and have credible financing?; (3) process management — narrowing the field to 3-5 serious parties before investing time in management meetings.
The gap between IOI range and eventual closed price tends to narrow during the process: IOIs often come in 10-20% above where final bids land, reflecting preliminary enthusiasm that moderates with diligence findings. Buyers who anchor too high in IOIs to win access sometimes walk back dramatically at LOI — a practice called "IOI inflation" that sophisticated bankers screen for.
Seller vs. Buyer Perspective
IOIs are the seller's early scorecard on the process. A strong round of IOIs (multiple bidders in tight ranges) signals healthy market interest and price discovery; a weak round (few bidders or very wide ranges) signals process problems. Your banker should help you evaluate IOIs not just on price but on buyer quality: Do they have committed capital? Have they closed similar deals? Is their valuation thesis credible? Select 3-5 IOIs to advance to management meetings based on best combined fit — price, certainty, and strategic alignment. Beware of "IOI inflators" who top the range to win the meeting then walk back the price post-meetings.
IOIs are your foot in the door. Craft them carefully: (1) price range should be defensible to your own team later (don't inflate to win access); (2) demonstrate thesis clarity (why you want this specific business, what you see that others don't); (3) signal certainty (committed capital, prior closed deals, clear timeline); (4) identify open questions honestly. Bankers respect buyers who price IOIs realistically and walk to LOI near their IOI range; they distrust buyers who inflate to access then re-trade. Building a reputation as a "say what you mean" buyer pays over many deals.
Real-World Example
A sell-side process for a $4.5M EBITDA business sends CIMs to 27 pre-qualified buyers. First-round IOIs received: 12 (ranging from 4.0x to 6.8x multiples, $18M-$30.6M). The banker scores IOIs on five dimensions: price, certainty (has buyer closed similar deals?), fit, timeline, and terms. Four bidders advance to management meetings at roughly equivalent IOI ranges (6.0-6.5x) despite not being the top-priced: (1) a 6.8x IOI from a buyer with no prior closed deals gets dropped as likely IOI inflation; (2) 6.5x from a PE platform with strong track record advances; (3) 6.4x from a strategic buyer advances; (4) 6.2x from a family office with longer hold period advances; (5) 6.0x from an independent sponsor with strong references advances. The 6.8x bidder is excluded because their closing probability was judged too low. Final closed deal: 6.3x at $28.4M with the PE platform, closely matching the mid-point of qualified IOI range.
Why It Matters & Common Pitfalls
- !IOI inflation is a real problem. Some buyers inflate IOIs to gain access, then walk back in LOI. Experienced bankers track this across deals.
- !Price range discipline. IOIs should commit to a tight range (10% spread at most). Wide ranges ($15-25M) signal lack of thesis.
- !Qualification screens matter. Bankers reject IOIs from buyers without evidence of capital or deal-closing capability.
- !Preliminary by design. IOIs aren't binding and shouldn't include extensive conditions — the purpose is expressing interest, not pre-negotiating.
- !Timing pressure. Banker deadlines for IOIs are real; late IOIs often get dropped regardless of quality.
- !Strategic vs. financial buyers bid differently. Strategic IOIs often come in higher but with synergy-dependent assumptions; financial IOIs are more disciplined to standalone cash flows.
