7 Top M&A Advisory Firms in the US in 2024

The right M&A advisory firm doesn’t just facilitate a transaction; it enhances the value of your deal through:

  • Experience and expertise
  • Industry insight
  • Strategic advice
  • Expert negotiation
  • Comprehensive support 

I know this because I’ve been leading my M&A advisory firm, Eton Venture Services, for the past 15 years. 

From 409A valuations to contentious M&A appraisals, our team of ex-Big 4 consultants use robust methodologies that stand up in court to avoid unnecessary costs and complications. 

To help you find the most reliable and accurate M&A advisory firm, I put together this article.

I explain four factors you should look for in an advisory firm, and give you 7 recommendations for low-to-middle market transactions.

Each firm has a unique focus area or industry, so you can pick one that meets your needs. 

What to Look For in an M&A Advisory Firm [4 Factors]

When selecting an M&A advisory firm, it’s important to focus on a few key factors. 

Based on my 15 years of experience, these factors significantly impact how well your deal works out:

Factor 1: Experience & Expertise

You want to work with advisors who have a sophisticated understanding of the M&A process.

Experienced and expert advisors know all about:

  • Market trends
  • How to value businesses
  • The best ways to structure a deal to maximize value
  • How to handle complex negotiations
  • Spot potential problems and how to fix them before they escalate

You can ask the following questions to gauge their experience and expertise:

  • How many years of experience do they have in the industry?
  • How many M&A valuations have they done to date?
  • Have the valuations they’ve produced been accepted, accurate, and defensible?

Pick a firm that specializes in your industry or similar business sectors. 

Specialization often means the firm has valuable industry connections and a nuanced understanding of market-specific trends and valuation metrics, which can lead to better and even quicker deal outcomes.

To gauge their experience in your niche:

  • Check if their websites highlight experience in your particular sector.
  • Ask them for names of past clients they have worked with in your industry.

The reputation and credibility of an advisory firm are vital.

A reputable advisor ensures that all dealings are transparent and in line with legal and ethical standards.

Check their history, client testimonials, and industry recognition to gauge their standing.

Customer service and support are important both during and after an M&A deal. 

You should receive prompt, clear answers to your concerns and questions, and receive guidance throughout the entire process.

This ongoing support is important for smooth post-merger integration and for addressing any issues that might arise afterwards.

For example, at Eton, we are prepared to defend M&A valuations in court later if necessary.

M&A Advisory Firms – FAQs

Have more questions about M&A advisory firms? I answer them below:

What is an M&A advisory firm?

An M&A (Mergers and Acquisitions) advisory firm provides expert advice and services to companies involved in mergers, acquisitions, and other corporate restructuring activities.

Here are some of the key roles and services provided by M&A advisory firms:

  • Valuation: They assess the value of businesses to determine a fair price for transactions.
  • Due Diligence: They conduct thorough investigations into the financial, legal, and operational aspects of the target company to uncover any potential risks or liabilities.
  • Deal Structuring: They help design the structure of the deal to maximize financial and strategic benefits while minimizing risks.
  • Negotiation: They assist in negotiating terms with the other party to secure the best possible deal.
  • Financing: They help in arranging financing for acquisitions, including identifying and securing funding from banks, private equity firms, or other sources.
  • Integration Planning: They provide guidance on integrating the operations, cultures, and systems of merging entities to ensure a smooth transition and to realize synergies.

Consulting firms play a critical role in mergers and acquisitions (M&A) by advising companies on strategic decisions, valuations, and integration processes. 

They provide expertise in areas such as due diligence, where they assess the financial health and business prospects of potential acquisition targets.

Consulting firms also help in structuring deals to maximize financial and strategic value, and they offer guidance on regulatory compliance to ensure smooth transaction approvals. 

Post-merger, they assist with the complex task of integrating operations, cultures, and systems to achieve the desired synergies. 

Their objective insight and specialized skills are invaluable in navigating the complexities of M&A transactions effectively.


It’s hard to nail down the “best” consulting firm for M&A since we don’t know your actual circumstances.

The right choice for you will depend heavily on the sector you’re in, company revenue range, and the level of expertise you seek. 

In this article, I shared my top 7 recommendations for M&A advisory firms. Each firm has a unique focus and expertise. 

For instance, Eton Venture Services focuses on buy-and-sell-side advisory for private equity firms with $5M to $150M revenue range, while Sica | Fletcher focuses on M&A advisory for insurance companies with $1M to $30M revenue range.
