The IOI is the document seller-side advisors most often underemphasize and buyer-side advisors most often try to skip past. The structural reason: the IOI is where the competitive process actually creates value. Skip it, and the seller anchors on whichever buyer's first offer they happened to take seriously. Run it well, and the seller establishes a defensible valuation floor backed by competing capital.
What the IOI is, and isn't.
The IOI is a structured, written expression of serious acquisition interest at a defined range of terms. It is not a contract. Either side can walk away without legal exposure for any reason or no reason at all. The non-binding status is essential to its function: buyers can express real interest at real numbers without the cost-of-commitment that an LOI carries, and sellers can collect multiple expressions and compare them against each other.
What the IOI does signal:
- Serious intent. A buyer willing to put numbers on paper has done at least preliminary internal validation. Tire-kickers don't issue IOIs.
- Capital posture. Strong IOIs name the source and form of capital — fund LP commitment, committed credit facility, SBA pre-qualification with named lender.
- Strategic fit. The structure and assumptions the buyer proposes reveal what they think they're buying and what they expect to do with it post-close.
- Pricing bracket. The valuation range tells the seller where this buyer sees the book in the multiple-band landscape (4–6× / 8–10× / 10–12× / 12–19×).
What every IOI must address.
An IOI that doesn't address all three of the Big Three components isn't really an IOI — it's an expression of curiosity. The components:
| Component | What it looks like | Why it matters |
|---|---|---|
| Valuation range | "$X–Y million" or "8.5–9.5× Normalized EBITDA" | Defines the multiple band the buyer is operating in |
| Deal structure | Asset vs. stock; cash/earn-out/note/rollover mix | Determines tax treatment and risk profile for the seller |
| Payout method | % cash at close, % earn-out, % seller note, % rollover | Determines headline-vs-wire spread and PV math |
The most-underspecified component is consistently the payout method. Buyers prefer to leave it vague at the IOI stage because they want flexibility to compress cash-at-close during LOI negotiation. Strong sellers refuse to advance an IOI to LOI without explicit payout language — the structural commitment is what the IOI exists to surface.
Three IOIs make a market.
The strategic value of the IOI is in collecting multiple of them. One IOI is a starting position — useful, but the seller doesn't know whether it represents the market or one outlier buyer's enthusiasm. Three IOIs is a market — the seller can compare ranges, see structural patterns, and identify which buyer is genuinely competitive and which is window-shopping.
The single-IOI seller anchors on whichever buyer happened to write first. The three-IOI seller anchors on the buyer who actually has to compete to win. The difference between those two negotiating postures is consistently a meaningful fraction of the multiple — often a full turn in well-prepared books.
The mechanics of running a multi-IOI process:
Same timeline, same package.
- All qualified buyers receive the same Agency Questionnaire and disclosure package.
- Same response deadline for all IOIs.
- Same evaluation framework applied to each.
- Transparency on the process (not the offers) — buyers know they're competing.
3–5 credible bidders.
- Pre-qualified through the screening funnel (buyer vetting).
- Mix of archetypes when possible — PE, strategic, individual.
- Each independently capable of closing.
- Quality matters more than quantity beyond 5.
PV-equivalent, not headline.
- Discount earn-out by realistic probability.
- Discount seller note by credit risk and timing.
- Value rollover at NPV of likely exit.
- The PV-comparable offer that wins is the offer that wins in practice.
Use the strongest IOIs as leverage.
The IOI's most-valuable role comes at the transition to LOI. The seller doesn't just pick one IOI and negotiate it; the seller uses the field of IOIs to negotiate the LOI from the strongest position. The structural moves:
- Confirm range alignment. The LOI's headline price should sit at or above the top of the strongest IOI's range, not at the bottom of the average.
- Lock in payout method. The mix of cash, earn-out, seller note, and rollover defined in the IOI should carry forward into the LOI. Drift between IOI and LOI on payout structure is the most common buyer move.
- Time-box exclusivity. The strongest IOI's terms inform what exclusivity duration is reasonable. Shorter is better — 30–45 days standard, up to 90 days in larger deals.
- Keep the backup field warm. Even after granting exclusivity to one buyer, sellers should maintain dignified, defined communication with the next-best buyer in case the lead deal collapses.
