An indication of interest (IOI) is an informal, non‑binding expression that a buyer is interested in purchasing an asset. In capital markets it most commonly refers to a prospective investor’s conditional interest in buying shares in a company before an offering is priced and the securities are cleared for sale (for example, during an IPO registration period). In mergers and acquisitions (M&A) an IOI is an early written expression from a potential acquirer that signals genuine interest in buying a target and sets out high‑level economic terms and conditions that could lead to a letter of intent (LOI) and then a definitive purchase agreement (Investopedia; SEC).
Key characteristics
– Non‑binding: An IOI does not create a legal obligation to buy or sell. It signals intent only. Selling a security while it’s in SEC registration is illegal, so IOIs are conditional (SEC; Investopedia).
– Early‑stage: Occurs before formal pricing (IPOs) or before an LOI (M&A).
– Informational: Gives counterparties a sense of demand, pricing expectations, and seriousness. For investors in an IPO, brokers must give a preliminary prospectus (the “red herring”) when taking IOIs (SEC; Investopedia).
– Allocation risk: Placing an IOI does not guarantee allocation; IPO allocations are often first‑come, first‑served or otherwise determined by the underwriters (Investopedia).
– Variety of forms: In trading systems, IOIs can be simple electronic messages advertising interest, or longer letters in M&A that outline valuation ranges and deal conditions (Investopedia).
How an IOI works (securities / IPOs)
1. Company files registration statement with the SEC. Securities cannot be sold until the SEC declares the registration effective.
2. Underwriters and brokers solicit IOIs from clients to gauge demand and help set an offer price. Brokers must provide the investor the preliminary prospectus (red herring) when soliciting interest (SEC; Investopedia).
3. Investors provide IOIs indicating size and a price range or willingness to participate. These are non‑binding and can be canceled.
4. Underwriter determines final price and allocations based on demand and other considerations. IOIs influence pricing and allocation but do not guarantee an order (Investopedia).
How an IOI works (M&A)
1. Potential buyer submits an IOI letter to the seller (often after viewing a teaser and signing an NDA).
2. IOI typically contains a high‑level valuation range, proposed structure (cash / stock / mix), key conditions (financing, regulatory approvals), a suggested timeline, and may request exclusivity or outline retention proposals for management. It is used to screen buyers and prioritize due diligence access (Investopedia).
3. If buyer and seller proceed, the next step is an LOI or term sheet, followed by detailed due diligence and negotiation of the definitive purchase agreement.
IOI vs. LOI
– IOI: Earlier, informal and non‑binding; provides valuation ranges and broad terms to begin engagement.
– LOI (Letter of Intent): More detailed and usually follows an accepted IOI; still typically non‑binding for the purchase price and key deal terms but often contains binding provisions (e.g., confidentiality, exclusivity, break fees). An executed LOI frequently starts exclusivity periods and more formal due diligence (Investopedia).
Actionable IOI
– Definition: An “actionable” IOI gives enough specifics that it could be acted on by the broker or market—e.g., security symbol, price at or above the National Best Bid and Offer (NBBO), and a size. Actionable IOIs can be subject to confirmation windows; if not confirmed, they can be cancelled automatically (Investopedia; FINRA).
Natural IOI
– Definition (per FINRA): A “natural” IOI originates with the customer (not the firm) or is a proprietary interest established to fill a customer order or execute on a riskless principal basis. Natural IOIs are distinguished from firm‑generated or marketed interest (FINRA).
Who can cancel an IOI?
– The buyer (or the buyer’s broker) may cancel an IOI. If an IOI remains unconfirmed past any applicable confirmation period, it will be canceled automatically. For retail investors, platform/broker policies (and FINRA rules) determine timing and cancellation mechanics (SoFi; FINRA).
Practical steps — If you are an investor considering submitting an IOI (IPO context)
1. Understand the nature of IOIs: non‑binding, used to gauge demand, allocation not guaranteed (Investopedia).
2. Read the preliminary prospectus (red herring) provided by your broker—review business fundamentals, risks, use of proceeds, and lockups (SEC; Investopedia).
3. Decide size and price range you’re willing to express; consider that IOIs are frequently handled on a first‑come basis. Keep in mind actionable IOIs require price/symbol/size if you intend to be actionable.
4. Communicate with your broker about confirmation windows, cancellation policy, and how allocations will be determined on the offering.
5. Prepare for post‑allocation steps: if allocated, you’ll receive final offer details and settlement instructions. If not allocated, no purchase obligation exists.
Practical steps — If you are a buyer preparing an IOI (M&A context)
1. Gather key inputs: high‑level valuation (range), proposed deal structure (cash/stock), source of financing or financing certainty, and timeline for due diligence and closing.
2. Sign an NDA or request one from the sell‑side before receiving confidential materials.
3. Draft IOI letter covering: valuation range, proposed structure, high‑level conditions/assumptions, any proposed management/retention terms, request for exclusivity (if desired), and an anticipated timetable. State clearly that the IOI is non‑binding except for any narrowly binding provisions (e.g., confidentiality).
4. Provide proof of funds or financing commitments if requested.
5. Coordinate internal resources (legal, tax, accounting, bankers) to be ready to move quickly to LOI and due diligence if seller accepts.
Practical steps — If you are a seller responding to IOIs (M&A context)
1. Log and compare IOIs on valuation, certainty of financing, proposed structure, and timeline.
2. Request proof of funds or financing availability for bidders that pass initial screens.
3. Use IOIs to shortlist buyers for management presentations and due diligence access.
4. Negotiate exclusivity carefully—short periods reduce market risk but may increase buyer leverage and reduce competitive tension. Consider break fees or milestones in subsequent LOI if exclusivity is granted.
5. Move the most credible buyer(s) to a more detailed LOI and start formal due diligence.
Example (real‑world)
– In May 2008 Blackbaud’s CEO submitted a revised IOI to Kintera’s chairman indicating interest in acquiring 100% of the company and asking for a time‑bound exclusive negotiation window in exchange for a higher all‑cash offer. The IOI outlined management retention proposals, exclusivity conditions, and expressly stated it was non‑binding and time‑limited (Investopedia).
Important regulatory and practical notes
– Securities in a U.S. registration cannot be sold prior to SEC effectiveness; therefore, IOIs for registered securities are conditional and non‑binding until the offering is effective (SEC; Investopedia).
– Brokers taking IOIs must provide the preliminary prospectus to the investor (SEC).
– FINRA provides guidance on IOIs in trading environments, including definitions of actionable and natural IOIs and transparency expectations (FINRA).
– Company boards and management should treat IOIs as screening tools, not commitments. Buyers should expect to move from IOI to LOI and then to definitive agreements if both sides want to proceed.
Practical checklist — What to include in an M&A IOI
– Buyer identification and contact details
– Statement of intent and non‑binding nature (except limited binding items)
– High‑level valuation range and pricing methodology
– Proposed transaction structure (cash / stock / earnout / mix)
– Financing status (sources, committed financing, or subject to financing)
– Key conditions and assumptions (due diligence scope, regulatory approvals)
– Proposed timeline and milestones
– Request or offer of exclusivity and proposed exclusivity period
– Management retention/transition proposals (if applicable)
– Expiration / response deadline for the IOI
The bottom line
An IOI is an early, conditional expression of interest used in both securities offerings and M&A. It’s a practical tool for determining demand and initiating negotiations but is not a binding purchase obligation. For investors, an IOI helps signal demand and may influence pricing/allocation in an offering; for M&A parties, an IOI is a screening document that sets the stage for more detailed negotiation and due diligence that follow an LOI.
