What Is an Indication of Interest (IOI), and When Should I Use One?

Alexej Pikovsky Avatar

An Indication of Interest (IOI) is a pivotal document used across various financial and investment processes. While non-binding, it serves as a preliminary signal of intent from a buyer or investor. Whether in mergers and acquisitions (M&A), initial public offerings (IPOs), or block trades, an IOI bridges the gap between exploratory discussions and formal agreements. In this article, I’ll break down what an IOI is, its key components, how it differs from a Letter of Intent (LOI), and the circumstances under which it’s most effectively used.

What Is an Indication of Interest (IOI)?

At its core, an IOI is a preliminary step in negotiations. It allows a buyer to signal interest in a deal without committing to binding terms. This makes it a valuable tool in situations where more information is needed before finalizing a transaction.

IOIs are typically used in:

  1. Mergers and Acquisitions (M&A): A buyer uses an IOI to express interest in purchasing a business and outlines initial terms for further discussion.
  2. Initial Public Offerings (IPOs): Investors indicate their intent to buy securities once they are approved for public sale.
  3. Block Trades: Large-scale transactions in securities markets use IOIs to gauge interest without disrupting market stability.

By clearly laying out the buyer’s intentions and conditions, an IOI serves as a roadmap for moving the transaction forward, or deciding that it isn’t a fit.

Why Are IOIs Important?

Indications of Interest (IOIs) are fundamental in the early stages of financial transactions, offering a structured yet non-binding way for buyers and sellers to explore potential deals. They are particularly useful in complex or high-stakes situations where both parties need a clear framework to discuss terms without the pressure of immediate commitments. By providing flexibility and clarity, IOIs help ensure that negotiations begin on solid ground, fostering trust and efficiency in the process.

One of the primary benefits of IOIs is their role in preliminary exploration. Buyers often need to signal their intent while still assessing the viability of a deal, especially in unfamiliar or intricate transactions. By outlining key elements like valuation ranges and funding methods, an IOI allows buyers to express serious interest while retaining the freedom to refine their proposal after due diligence. For sellers, IOIs act as an early indicator of a buyer’s commitment level and financial capability, offering reassurance without binding them to a specific course of action.

Beyond exploration, IOIs streamline communication and mitigate risk. They provide a formal structure to share essential details, ensuring that both parties are aligned before advancing to binding agreements. This structured yet flexible approach helps avoid misunderstandings and unnecessary complications, making IOIs an indispensable tool for navigating the complexities of modern financial transactions.

Key Components of an IOI

A well-prepared IOI contains specific elements that outline the buyer’s intentions and provide a framework for further negotiations.

1. Approximate Price Range

The buyer proposes a valuation for the asset or company, either as:

  • Dollar Range: For example, $15–20 million.
  • Multiple of EBITDA: For instance, 4–6x earnings before interest, taxes, depreciation, and amortization.

This helps the seller gauge whether the buyer’s valuation aligns with their expectations.

2. Source of Funds

An IOI specifies how the buyer plans to finance the transaction, such as:

  • Cash Reserves: Funds readily available to the buyer.
  • Debt Financing: Loans or credit lines.
  • Equity Financing: Capital raised from investors.

This reassures the seller of the buyer’s ability to complete the deal.

3. Due Diligence Requirements

This section outlines the buyer’s requests for additional information, such as:

  • Financial statements.
  • Tax records.
  • Contracts with customers or suppliers.
  • Intellectual property details.

A timeline for conducting due diligence, typically weeks to months, is also included.

4. Proposed Deal Structure

The IOI describes the basic framework of the deal, including:

  • Asset vs. Equity Purchase: Whether the buyer plans to acquire specific assets or full equity ownership.
  • Payment Terms: Cash, equity, or a combination.
  • Contingencies: Conditions that must be met for the deal to proceed.

5. Management and Ownership Post-Transaction

In M&A, the IOI may address the roles of current stakeholders after the deal, such as:

  • Retention of the management team.
  • Future involvement of current owners.

6. Estimated Closing Timeline

An IOI provides an approximate timeline for completing the transaction, which helps both parties plan their next steps.

IOI vs. Letter of Intent (LOI)

While both IOIs and LOIs are non-binding, they differ in their purpose and level of detail.

AspectIOILOI
PurposeIndicates preliminary interestOutlines specific terms of a proposed deal
Binding StatusNon-bindingNon-binding, but more detailed
Level of DetailGeneral terms (e.g., price range, financing source)Specific terms (e.g., exact price, exclusivity clauses)
TimingUsed in the early stagesFollows due diligence and more in-depth discussions

An IOI is like saying, “I’m interested in learning more,” whereas an LOI communicates, “I’m ready to commit under specific conditions.”

When to Use an IOI

An Indication of Interest (IOI) is a versatile tool that plays a significant role in various types of financial transactions. It is particularly valuable during the early stages of negotiations when there’s a need to signal intent, establish preliminary terms, or gather additional information. This section delves deeply into the scenarios where IOIs are most commonly used and highlights how they facilitate different processes, such as mergers and acquisitions (M&A), initial public offerings (IPOs), and block trades.

1. In Mergers and Acquisitions (M&A)

Mergers and acquisitions often involve complex negotiations and multiple stages before reaching a final agreement. IOIs are a natural fit in the early stages of these transactions, where they help establish initial interest and set the tone for future discussions. There are two primary scenarios in M&A where IOIs are particularly useful: proprietary deals and uncertain transactions.

Proprietary Deals

Proprietary deals refer to transactions where a buyer negotiates directly with a seller without the involvement of intermediaries like brokers or investment bankers. These deals are often initiated by the buyer, who may reach out to a business owner that hasn’t actively listed their company for sale.

In these situations, an IOI serves as an introduction and a starting point for discussions. By presenting an IOI, the buyer signals serious interest while outlining preliminary terms, such as a price range, financing plans, and proposed timelines. This can help build trust and establish credibility with the seller, who may be cautious about engaging in negotiations without a formal listing or broker guidance.

For example, a buyer interested in acquiring a mid-sized manufacturing company might submit an IOI stating their intent to pay within a specific valuation range (e.g., $15–20 million) and detailing their financing sources. This approach provides the seller with clarity about the buyer’s intentions while leaving room for further exploration.

Uncertain Transactions

In some M&A deals, the buyer may not have enough information to make a definitive offer upfront. This is especially true when financial details or operational metrics are unclear, or when the business operates in a niche market with limited public data.

An IOI allows the buyer to express interest while requesting additional information to assess the viability of the deal. For instance, the IOI might specify that the buyer is interested in the business, provided that due diligence reveals consistent revenue growth and no significant liabilities. This approach benefits both parties: the buyer avoids premature commitments, and the seller receives a clear indication of the buyer’s intent.

Using an IOI in such cases ensures that the conversation progresses without rushing into a binding agreement, creating an opportunity for both sides to evaluate the transaction thoroughly.

2. Before an Initial Public Offering (IPO)

In the context of IPOs, IOIs are used by investors to indicate their interest in purchasing shares of a company preparing to go public. These non-binding expressions of intent help underwriters gauge market demand, set pricing strategies, and allocate shares effectively.

How IOIs Function in IPOs

When a company plans to go public, underwriters often solicit IOIs from institutional investors, such as mutual funds, pension funds, and hedge funds. These investors submit IOIs specifying the number of shares they are interested in buying and, in some cases, the price range they are willing to consider.

For example, an institutional investor might submit an IOI indicating their intent to purchase 100,000 shares at a price range of $20–25 per share. This information helps underwriters determine how much demand exists for the company’s stock and whether the proposed price range aligns with market expectations.

While submitting an IOI does not guarantee that the investor will receive the desired shares, it demonstrates their seriousness and positions them as a priority for allocation. This is especially important in oversubscribed IPOs, where demand exceeds supply.

Why IOIs Matter in IPOs

IOIs play a critical role in ensuring the success of an IPO. By collecting these expressions of interest, underwriters can:

  • Adjust Pricing: If demand is significantly higher or lower than expected, the company can adjust the offering price to maximize value.
  • Refine Allocation: Underwriters can prioritize allocations to investors who submitted IOIs, ensuring a balanced and supportive shareholder base.
  • Mitigate Risk: IOIs provide a preview of investor sentiment, reducing the likelihood of a poorly received offering.

For investors, submitting an IOI can increase their chances of securing shares in a sought-after IPO, particularly when demand is high.

3. In Block Trades

Block trades involve the purchase or sale of a large quantity of securities, typically negotiated privately between parties to avoid market disruptions. In such transactions, IOIs are used to facilitate coordination and gauge interest among potential buyers or sellers.

The Role of IOIs in Block Trades

Block trades are often executed by institutional investors, such as mutual funds or pension funds, looking to buy or sell significant positions in a security. These large transactions can impact market prices if not handled carefully. To minimize disruption, traders use IOIs to communicate their intent and identify counterparties willing to participate in the trade.

For instance, a fund manager seeking to sell 1 million shares of a particular stock might issue an IOI to a network of potential buyers. The IOI would outline the details of the proposed trade, including the security name, the number of shares, and the desired price range. Interested buyers can then respond, allowing the trade to be negotiated efficiently without broadcasting the transaction to the broader market.

Benefits of Using IOIs in Block Trades

  • Preserving Market Stability: By conducting trades privately, IOIs help prevent significant price fluctuations that might occur if the trade were executed on the open market.
  • Improving Liquidity: IOIs attract potential counterparties, ensuring that large trades can be completed without delays or complications.
  • Streamlining Negotiations: By providing clear terms upfront, IOIs make it easier for both parties to agree on the details of the trade.

Real-World Example

Imagine an asset manager wants to acquire a large position in a technology company. Rather than placing a massive buy order on a public exchange, which could drive up the stock price, the manager issues an IOI to gauge interest among large sellers. This approach allows the manager to negotiate favorable terms while maintaining discretion.

Why IOIs Are Valuable Across Scenarios

Across these scenarios – M&A, IPOs, and block trades – IOIs serve a common purpose: facilitating the early stages of complex transactions. They provide a structured way to express interest, share preliminary terms, and explore the feasibility of a deal without binding commitments.

For buyers, IOIs offer a chance to gather information and negotiate from a position of strength. For sellers, they provide a clear signal of interest and a starting point for evaluating potential offers. Whether used to initiate a corporate acquisition, secure shares in a public offering, or execute a large trade, IOIs play a critical role in aligning the expectations of all parties involved.

By understanding when and how to use an IOI, businesses and investors can navigate these processes with greater confidence and efficiency. The flexibility and transparency offered by IOIs make them an indispensable tool in the world of finance and investment.

Advantages and Limitations of IOIs

Advantages:

  • Flexibility: IOIs allow buyers and sellers to explore deals without immediate commitments.
  • Transparency: Key terms like price and structure are outlined clearly.
  • Market Insights: Helps gauge interest and demand in IPOs and block trades.

Limitations:

  • Non-Binding Nature: Terms are not legally enforceable.
  • Limited Specificity: May lack the detail required for certain sellers to make decisions.
  • Potential Redundancy: In broker-led transactions, IOIs may be unnecessary.

Best Practices for Drafting an IOI

  1. Be Clear and Concise: Clearly outline your intentions and terms.
  2. Tailor to the Situation: Include details relevant to the specific transaction type (e.g., M&A vs. IPO).
  3. Avoid Ambiguity: Use precise language to prevent misunderstandings.
  4. Focus on Feasibility: Ensure proposed terms are realistic and align with market conditions.

When to Avoid Using an IOI

While an Indication of Interest (IOI) can be a valuable tool in negotiations, there are circumstances where skipping this step may be more efficient. In broker-led deals, for instance, intermediaries like brokers or investment bankers often provide comprehensive information packages, including financial statements, market analyses, and projections. These Offering Memorandums (OMs) equip buyers with sufficient insights to make informed decisions without requiring an exploratory IOI. In such cases, moving directly to a Letter of Intent (LOI) demonstrates a buyer’s seriousness and streamlines the process by avoiding redundancy.

Time-sensitive transactions are another scenario where bypassing an IOI is advisable. In competitive or high-pressure environments, sellers may favor buyers who can present firm commitments quickly. An IOI, being non-binding and preliminary, may not convey the level of seriousness needed to stand out among multiple interested parties. In these situations, submitting a detailed LOI with specific terms can provide a competitive edge and increase the likelihood of securing the deal.

Fast-moving market conditions also reduce the practicality of an IOI. In industries where valuations fluctuate or regulatory landscapes evolve rapidly, timing is critical. Sellers in such markets may prioritize buyers who can commit promptly, as the non-committal nature of an IOI might not inspire confidence. For example, in IPO scenarios with rapidly shifting investor demand, underwriters often prioritize investors ready to proceed with binding commitments over those expressing preliminary interest.

In summary, while IOIs are useful in many contexts, they may be unnecessary when detailed information is readily available, timing is crucial, or competitive dynamics demand immediate action. Understanding when to proceed directly to an LOI can save time, resources, and position buyers more favorably in negotiations.

Conclusion

An Indication of Interest (IOI) is a powerful yet flexible tool for navigating the early stages of financial transactions. Whether you’re working on mergers and acquisitions, preparing for an IPO, or executing block trades, IOIs provide a structured way to express interest, establish preliminary terms, and gather critical information. While non-binding, they serve as a foundation for smoother negotiations, ensuring both parties align on expectations before diving into formal agreements.

By understanding when to use an IOI and when to bypass it in favor of more direct steps, businesses and investors can save time, reduce risks, and maximize efficiency. In a world of complex financial dealings, the IOI remains a key instrument for fostering clarity, trust, and strategic decision-making.

FAQs

What is an IOI, and how is it used?

An Indication of Interest (IOI) is a non-binding document or letter used to signal a buyer’s interest in a transaction. It outlines preliminary terms such as price range, funding sources, and proposed deal structure. IOIs are commonly used in mergers and acquisitions, IPOs, and block trades to initiate discussions and explore the feasibility of a deal.

Is an IOI legally binding?

No, an IOI is not legally binding. It is simply a formal expression of interest that allows both parties to explore a transaction without committing to specific terms.

How is an IOI different from a Letter of Intent (LOI)?

An IOI is used early in the negotiation process to express preliminary interest, while an LOI comes later and provides more detailed, specific terms of a proposed deal. Both are non-binding, but an LOI typically signals a higher level of commitment.

When should I use an IOI?

IOIs are ideal for early-stage transactions where the buyer needs to gather more information before committing to a deal. They are particularly useful in proprietary M&A deals, IPOs, and block trades to gauge interest and establish preliminary terms.

When should I skip an IOI?

It’s best to skip an IOI in broker-led deals where detailed information is already available, in time-sensitive transactions, or in highly competitive scenarios where an LOI would demonstrate greater commitment.

Can IOIs be revised?

Yes, IOIs are non-binding, so their terms can be updated as the buyer gathers more information or as negotiations progress.
