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

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)?

An Indication of Interest (IOI) is a preliminary step in various types of financial transactions. It allows a party, typically a buyer or investor, to signal interest in pursuing a deal without committing to binding terms. While the concept is consistent across contexts, the format, purpose, and level of detail can vary significantly depending on the type of transaction. This flexibility makes IOIs a valuable tool in scenarios where more information or initial alignment is needed before moving toward a formal agreement.

IOIs in Mergers and Acquisitions (M&A)

In M&A transactions, an IOI is generally a formal letter submitted by a potential buyer to the seller (or their advisor). It outlines the buyer’s interest in acquiring the business and typically includes key terms such as a proposed valuation range, funding sources, and a timeline for due diligence. This stage often follows preliminary steps like the seller distributing a “Teaser” or a Confidential Information Memorandum (CIM) to prospective buyers. These materials provide potential buyers with enough information to evaluate the opportunity and submit an IOI, making it clear that an IOI doesn’t appear “out of nowhere” but is part of a structured process.

IOIs in Initial Public Offerings (IPOs)

In IPOs, an IOI takes on a different format and purpose. It is usually an informal expression of interest submitted by institutional investors to underwriters. The IOI communicates how many shares the investor might purchase and at what price range. This feedback helps underwriters gauge demand for the offering and adjust pricing or allocation strategies accordingly. Unlike M&A IOIs, IPO IOIs are not formal documents but rather serve as a tool for demand forecasting and market analysis.

IOIs in Block Trades

In the context of block trades, an IOI is even more distinct. It is often a rapid inquiry or electronic trading signal sent by brokers to potential counterparties. The purpose is to gauge interest in buying or selling large quantities of securities without causing market disruptions. These IOIs are typically concise, focusing on the security, price range, and quantity involved, and are exchanged quickly to facilitate efficient execution.

Why IOIs Matter Across Scenarios

While the format and purpose of IOIs vary across M&A, IPOs, and block trades, the core principle remains the same: to indicate serious preliminary interest without creating binding obligations. By laying out intentions, conditions, and expectations, an IOI acts as a roadmap for determining whether a transaction should proceed. This clarity benefits all parties involved, ensuring that discussions are grounded in mutual understanding before more formal agreements are reached.

Understanding the nuances of IOIs in each context, whether as formal letters in M&A, demand signals in IPOs, or trading inquiries in block trades, highlights their adaptability and essential role in financial transactions.

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 generally non-binding, there are important differences in their purpose, level of detail, and the inclusion of binding provisions. While an IOI serves as a preliminary expression of interest, outlining broad terms and intentions, an LOI typically includes more specific terms and often incorporates binding provisions, such as confidentiality agreements, exclusivity clauses, or non-solicitation terms. These binding elements in an LOI ensure that certain aspects of the negotiation process are formalized, even though the overall agreement remains non-binding until finalized. This distinction underscores the more advanced stage of commitment represented by an LOI compared to an IOI.

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 with Exceptions: While IOIs are generally non-binding, they are often accompanied by binding provisions such as confidentiality clauses or Non-Disclosure Agreements (NDAs). These provisions ensure sensitive information exchanged during negotiations is protected. While these clauses don’t make the entire IOI binding, they are critical practical considerations, especially in M&A transactions.
• Limited Specificity: IOIs may lack the detailed information that some sellers require to evaluate a buyer’s intent effectively. Broad terms, such as approximate price ranges or general financing methods, can leave key aspects of the deal ambiguous, potentially slowing progress.
• Potential Redundancy in Broker-Led Deals: In transactions facilitated by brokers or investment bankers, comprehensive information is typically provided upfront, making the submission of an IOI unnecessary. In such cases, proceeding directly to a more detailed Letter of Intent (LOI) can save time and streamline the negotiation process.

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 certain scenarios where its use may seem less critical. However, this does not mean IOIs are entirely dispensable, even in these cases. For instance, in broker-led transactions, intermediaries such as brokers or investment bankers often provide detailed information packages, including Offering Memorandums (OMs) with financial statements, market analyses, and projections. These materials equip buyers with the insights needed to make informed decisions. While this may suggest moving directly to a Letter of Intent (LOI) is more efficient, brokers frequently request IOIs as a way to screen potential buyers. By requiring IOIs, brokers can filter out unserious offers and focus negotiations on credible parties, thereby streamlining the process.

In time-sensitive transactions, skipping the IOI may be advisable to avoid delays. In competitive or high-pressure environments, sellers often favor buyers who can present firm commitments quickly. An IOI, as a non-binding and preliminary document, might not convey the level of seriousness required to stand out among multiple interested parties. In such cases, submitting a detailed LOI with specific terms can provide a competitive advantage, signaling both intent and readiness to proceed.

Similarly, fast-moving market conditions can reduce the practicality of using an IOI. In industries where valuations are volatile or regulatory landscapes are shifting, timing is critical. Sellers in these situations may prioritize buyers who are ready to commit immediately. For example, in IPO scenarios where investor demand fluctuates rapidly, underwriters often favor investors who can proceed with binding commitments over those expressing only preliminary interest.

In summary, while IOIs are useful in many contexts, their role should be carefully evaluated based on the specifics of the transaction. Even in broker-led deals, where detailed information is readily available, IOIs often serve as an effective screening tool. However, in time-sensitive or competitive situations, moving directly to an LOI can save time, resources, and help buyers secure an advantageous position 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.
