Understanding the M&A Process from IOI to LOI

Introduction

The lower middle market ($3-15M EBITDA) represents one of the most active segments of the M&A landscape, with thousands of businesses changing hands each year. Yet for many buyers, the formal process of acquiring these businesses remains opaque and challenging to navigate effectively. This lack of process knowledge creates a competitive disadvantage, often resulting in missed opportunities or inefficient deployment of acquisition resources.

For less experienced strategic buyers understanding the structured approach that investment bankers like Quantive employ when representing sellers can dramatically improve your acquisition success rate. A thorough grasp of this process helps you present more compelling offers, allocate resources efficiently, and identify the most promising opportunities earlier.

Most importantly, buyers who understand the banker’s perspective and the seller’s journey can position themselves as preferred acquirers—those who not only offer attractive financial terms, but also demonstrate professionalism and reliability throughout the transaction lifecycle.

The M&A Process Timeline: Key Milestones

Before diving into specifics, it’s helpful to understand the typical timeline of a formal M&A process. The journey begins with an initial marketing phase lasting 2-4 weeks. During this period, once under NDA the banker will generally conduct a brief call with each potential buyer and distribute a Confidential Information Memorandum and bid process letter which outlines the sale parameters and expectations.

The Indication of Interest (“IOI”) submission period follows over the next 4-6 weeks, when buyers submit their preliminary, non-binding proposals based on information provided in the CIM and potentially other data provided. Prior to IOI submission sharing of confidential data is usually limited to that which is provided in the CIM. Selected buyers then advance to management presentations, typically spread across 2-3 weeks. After these meetings, serious contenders submit Letters of Intent (“LOI”) with detailed proposals and specific terms, usually within a 1-2 week window.

The chosen buyer then enters an exclusivity period (aka “Standstill Period”) to conduct thorough confirmatory due diligence and complete final documentation and transaction completion. The Standstill period will typically be 60 days. Altogether, this process typically spans 4-6 months from initial outreach to transaction close. Let’s examine each critical phase in detail.

Bid Process Letters: Setting the Stage

In a well structured M&A process, the sell-side banker will prepare a bid process letter (sometimes called a “process letter”) that serves as your roadmap for engaging with a specific acquisition opportunity. While sometimes overlooked, this document contains crucial information that should shape your approach.

Typically issued shortly after you sign a confidentiality agreement, these letters outline the process timeline with specific submission deadlines, information requirements for each phase, format expectations for submissions, key decision criteria the seller will use, rules of engagement with the management team, and potential transaction structures the seller may consider.

Savvy buyers pay particular attention to the deadlines and evaluation criteria. When a process letter emphasizes “cultural fit” or “transition approach” alongside valuation, it signals the seller’s priorities extend beyond maximizing purchase price. Similarly, specific questions about post-acquisition integration plans suggest the seller cares deeply about employee and customer continuity.

Indications of Interest (IOIs): Making Your First Move

The IOI represents your first formal expression of interest in acquiring the target company. While non-binding, IOIs serve multiple important functions in the M&A process.

The Buyer’s Perspective

From your standpoint as a buyer, the IOI accomplishes several goals. It establishes your credibility as a serious acquisition candidate and demonstrates your understanding of the business and its value drivers. The IOI communicates your interest level through valuation range and terms while preserving flexibility by keeping those terms high-level and non-binding. Perhaps most importantly, it positions your unique advantages as an acquirer, whether those relate to strategic fit, growth resources, or other value-adding capabilities.

A well-crafted IOI typically includes a valuation range with clear explanation of methodology, transaction structure considerations, financing sources and evidence of funding capability, timeline to closing with major conditions, strategic rationale explaining your interest, and information about your organization highlighting relevant experience. It’s also our experience that successful IOI’s thoughtfully express why the buyer is the right fit for the transaction, demonstrates their past experience in acquiring, and if this is their first deal addresses head on their level of preparation and committment to consumating a transaction.

The Seller’s Perspective

For sellers and their advisors, IOIs serve a critical filtering function. With potentially dozens of interested parties, IOIs help identify which buyers have realistic valuation expectations and possess genuine acquisition capabilities. They reveal which potential acquirers understand the strategic potential of the business, offer favorable terms beyond just purchase price, and represent a good cultural and business fit.

The Banker’s Role in Buyer Selection

Investment bankers like Quantive typically score and rank IOIs across multiple dimensions beyond simply purchase price. This evaluation determines which buyers advance to management presentations—usually only 4-8 candidates from a potentially much larger initial pool.

Key factors often include valuation range relative to seller expectations, transaction certainty including financing and regulatory concerns, previous transaction history and reputation, strategic fit and potential synergies, and cultural compatibility. To maximize your chances of advancing, your IOI should demonstrate thorough understanding of the business, realistic but attractive valuation parameters, and clear articulation of why you represent an ideal acquirer beyond just financial considerations.

Management Presentations: Your Critical Face-to-Face Opportunity

Advancing to management presentations represents a significant milestone—it means you’ve cleared the initial screening and are now among a select group of serious contenders. This phase provides your first direct access to the company’s leadership team and represents a pivotal evaluation opportunity for both sides.

Preparation Is Essential

Before the meeting, thoroughly review all materials provided and prepare thoughtful questions that demonstrate your understanding of the business. Research suggests that buyers who come prepared with specific, strategic questions not only gather better information but also make stronger impressions on sellers.

Your objectives during these sessions should include validating key assumptions that underpin your valuation, assessing the management team’s strengths and capabilities, identifying potential integration challenges or opportunities, understanding the company culture and employee dynamics, and clarifying growth opportunities and market positioning.

Management presentations typically include detailed operational reviews, financial performance discussions, and strategic planning insights. The format varies but often includes both formal presentations and informal interaction opportunities.

Making a Strong Impression

Remember that while you’re evaluating the business, the seller’s team is simultaneously evaluating you. Successful buyers approach these meetings with a balance of due diligence and relationship building. Demonstrating that you understand and appreciate what makes the business special—while asking thoughtful questions about challenges—creates credibility.

After the presentation, prompt follow-up with clarifying questions shows continued interest and engagement. This period between management presentations and LOI submission offers a valuable opportunity to distinguish yourself from other potential acquirers.

Letters of Intent (LOIs): Moving to Committed Negotiations

The Letter of Intent represents a significant escalation in commitment. While still technically non-binding (except for specific provisions like exclusivity), LOIs signal serious intent to complete a transaction on defined terms.

From IOI to LOI: Key Differences

The transition from IOI to LOI involves several important shifts. Precision replaces ranges, with specific purchase prices replacing valuation ranges. Detailed structure replaces conceptual approaches, specific conditions replace general contingencies, and timeline commitments replace estimated windows. Exclusivity expectations also emerge as a central focus during this phase.

Essential Components of an Effective LOI

A comprehensive LOI typically includes purchase price and payment terms detailing cash (and sources of cash), as well as potential seller financing potential earnouts. (In our experience successful LOI’s typically do not contemplate seller finance, and earn outs are typically used to cover potential identified risks as opposed to being a mechanism to plug a financing gap). It specifies transaction structure considerations regarding asset versus stock deals and tax implications and tax true-up provisions for either asset deals or conversions (such as F Re-orgs and 338(h)10 elections). Working capital adjustments methodology, employee and management retention plans, and detailed conditions to closing are all addressed.

The LOI also outlines exclusivity period duration and terms, due diligence scope and timeline, representations and warranties expectations, and transition services and post-closing support arrangements. The exclusivity provision is particularly important, as it prevents the seller from entertaining other offers during your due diligence period. Sellers typically grant this valuable right only to buyers who present compelling, well-structured LOIs that demonstrate high probability of closing.

Most sellers and their advisors evaluate LOIs not just on headline price but on the collective terms and perceived certainty of close. A slightly lower offer with cleaner terms, fewer contingencies, and stronger evidence of closing capability often prevails over a higher but more uncertain bid.

Conclusion

Navigating the formal M&A process requires preparation, patience, and strategic thinking. By understanding each stage from both the buyer’s and seller’s perspectives, you can position yourself as a preferred acquirer while conducting thorough evaluation of potential acquisitions.

The most successful buyers in the lower middle market recognize that acquisition processes are both analytical and relational. They prepare thoroughly, communicate clearly, and demonstrate integrity throughout each phase—from initial interest through closing and beyond.
