# How do you become an M&A advisor?
No single licence makes an M&A advisor: you need deal skills, a clean answer to the securities-law question (US exemption explained) and your own deal flow.
---
You become an M&A advisor by learning to run a company sale or acquisition from first conversation to closing, usually inside a bank, an accounting firm or a boutique, then by settling the securities-law question for the country and state you work in, and finally by winning mandates of your own. No single licence or diploma creates the title; what clients pay for is a process they cannot run themselves while they keep managing the business.
The role exists at every size of deal, but most people who ask this question are aiming at the lower and middle market: privately held companies sold for a few million to a few hundred million dollars, where the advisor is often a small firm or a single experienced professional. That is the market described here. Where a legal rule is stated, the country or state it belongs to is named; the securities rules covered in detail are those of the United States, and all of it is general information, not legal advice.

## What does an M&A advisor actually do?
An M&A advisor manages the sale or the purchase of a company on behalf of one side: it prepares the business or the search, finds and approaches counterparties, runs the exchange of information and offers, and steers the negotiation until the money moves. The advisor does not replace the lawyer who drafts the contract or the accountant who checks the numbers; it runs the process those specialists plug into.
On an ordinary mandate that means several distinct jobs. The first is positioning: reading three to five years of accounts, restating the earnings so a buyer sees what the business really produces, and deciding what range of value is defensible. The second is marketing: an anonymous summary, a confidentiality agreement, then a detailed information memorandum. The third is the contest itself: collecting indications of interest, comparing offers that differ in price, structure and certainty, and negotiating a letter of intent. The fourth is due diligence, where the advisor keeps the data room moving and both sides at the table.
## How does the work differ on a sell-side and a buy-side mandate?
On a sell-side mandate the advisor runs a sale process for an owner and is paid mostly when the company sells; on a buy-side mandate the advisor searches for and approaches targets for an acquirer and is paid mostly when an acquisition closes. An owner who sells once needs the whole process, while a regular acquirer often has its own team and buys only the search.
| Criterion | Sell-side mandate | Buy-side mandate |
| --- | --- | --- |
| Client | Owner or shareholders of the company | Strategic acquirer, investor or search fund |
| Core work | Prepare, market, run offers, negotiate | Map targets, approach owners, assess fit |
| Exclusivity | Usually exclusive for a fixed term | Often limited to a sector or a target list |
| Main uncertainty | Whether a buyer meets the price | Whether a willing seller exists at all |
Fee structures follow the uncertainty. Since a buy-side search can consume a year without a closing, buy-side advisors tend to rely more on the monthly retainer, while sell-side advisors can accept a lighter retainer against a larger fee at closing. Acting for both sides of the same transaction is a conflict of interest that needs full written disclosure and written consent wherever it is permitted at all, and under the United States federal exemption described below, acting for both sides without those two documents removes the exemption.
## Where is the line between an M&A advisor and a business broker?
A business broker typically sells small owner-operated businesses, often as a sale of assets to an individual buyer, while an M&A advisor handles larger companies sold to corporate or financial buyers through a structured process, often as a sale of shares. The line is a convention, not a legal definition, and many firms work on both sides of it.
The practical differences sit in the buyer and the method. A main-street business, such as a restaurant or a shop, is usually advertised with a price and bought by someone who will run it personally. A company with a management team and corporate buyers is rarely advertised with a price at all: the advisor approaches a chosen list of buyers in confidence and lets their offers set the value. The second kind of deal also brings more complex terms, such as working capital adjustments, rollover equity and earn-outs, and it is far more likely to involve the transfer of shares, which is where securities law enters.
Becoming a business broker is its own path, with its own licensing questions, and is not covered here. Many M&A advisors start there and move up in deal size as their track record grows.
## What skills and backgrounds lead into M&A advisory?
M&A advisors come mainly from five backgrounds: investment banking, transaction work in accounting firms, corporate development or private equity, business ownership and corporate law. Each brings one part of the job and has to learn the others.
- **Investment banking analysts and associates** arrive with financial modelling, valuation and the discipline of a formal process. They usually have to learn how to originate work, because in a bank someone senior brought the client.
- **Accountants from transaction services or audit** read financial statements faster than anyone and know where a quality-of-earnings review will find problems. They have to learn selling and negotiation.
- **Corporate development and private equity professionals** know how buyers think, how an investment committee decides and what kills a deal in diligence. They have to learn to serve a client instead of being one.
- **Former owners and operators** carry credibility with sellers that no credential replaces, since they have been across the table. They have to learn the technical side, or pair with someone who has it.
- **Corporate lawyers** understand the contract and the risk allocation. They have to learn valuation and the marketing of a business.
Whatever the entry point, the working skills are the same. You must be able to normalise earnings and explain every adjustment, build a simple and honest valuation range, write a memorandum that a buyer's analyst will not tear apart, and manage a timetable with a dozen parties.
No general licence or degree is required to use the title "M&A advisor" in most places. Professional certifications issued by trade associations and training bodies can help a newcomer structure knowledge; none of them is a legal authorisation, and none replaces closed transactions when a seller checks your references. The legal authorisation question is a different one, and it comes from securities law.
## Do you need a securities licence to advise on a sale of shares in the United States?
In the United States, being paid a fee that depends on the closing of a sale of shares is broker activity under federal securities law, so an M&A advisor either registers as or associates with a broker-dealer, or fits within the federal exemption for M&A brokers in section 15(b)(13) of the Securities Exchange Act. That exemption, added by Congress in the Consolidated Appropriations Act, 2023 and effective since March 29, 2023, removes the federal registration requirement for advisors who work only on transfers of control of smaller private companies and stay inside its conditions.
The reason the question arises at all is that shares of a private company are securities. An advisor who sells the assets of a business is selling equipment, contracts and goodwill; an advisor who arranges the sale of all of a company's stock is effecting a transaction in securities, even though commercially the two deals look alike. The staff no-action letter that advisors relied on before was withdrawn by the staff of the Securities and Exchange Commission when the statutory exemption took effect, so the statute is now the text to read.
| Condition | What the federal statute requires |
| --- | --- |
| Target company | Privately held, with no class of securities registered and no periodic reporting obligation |
| Size ceiling | EBITDA under $25 million, or gross revenues under $250 million, or both, in the fiscal year before the engagement |
| Buyer | The advisor reasonably believes the buyer will control the company and be active in its management |
| Control | Presumed when the buyer holds 25% or more of a class of voting securities |
The statute then lists activities that take an advisor out of the exemption. An M&A broker relying on it may not receive, hold, transmit or have custody of the funds or securities exchanged in the deal; may not take part in a public offering; may not work on a transaction involving a shell company, apart from a narrow category of business-combination shells; may not provide financing for the deal, directly or through an affiliate; may not help form the group of buyers; may not arrange a sale to a passive buyer; and may not bind a party to the transfer. Helping a party obtain financing from an unaffiliated lender is allowed only if the advisor complies with the other applicable laws and discloses its compensation in writing. An advisor who has been barred or suspended from association with a broker-dealer by the Commission, a state or a self-regulatory organisation cannot use the exemption.
Two details are easy to miss. When a party is offered securities in exchange for the company, as in a sale paid partly in the buyer's stock, the statute requires that this party receive or have reasonable access to the issuer's most recent year-end financial statements and a balance sheet dated no more than 120 days before the offer, before becoming bound. And the dollar ceilings are not permanent: the statute provides for an inflation adjustment every five years, tied to an employment cost index published by the Bureau of Labor Statistics and rounded to the nearest $100,000, so the figures should be read in the current text.
Advisors whose work falls outside those limits take the registered route. That means associating with a broker-dealer that is a member of the Financial Industry Regulatory Authority and passing its qualification examinations. According to that authority, the Investment Banking Representative examination, known as the Series 79, covers advising on or facilitating mergers and acquisitions, asset sales, divestitures, tender offers, restructurings and securities offerings; it has 75 multiple-choice questions, lasts two hours and thirty minutes, requires a score of 73 to pass, has the Securities Industry Essentials examination as a corequisite and can only be taken by a candidate sponsored by a member firm. Raising capital through a private placement or placing a minority stake with passive investors are typical reasons an advisor needs that route.
## What do state rules add to the federal exemption?
The federal M&A broker exemption removes only the federal registration requirement: each state has its own securities law and its own broker-dealer registration, and an advisor must also be exempt or registered in the states where it does business. Fitting the federal conditions is necessary for an unregistered advisor in the United States, but it is not sufficient.
The North American Securities Administrators Association, which groups the state regulators, adopted a model rule exempting M&A brokers on September 29, 2015, built on conditions close to the federal ones. A model rule binds nobody until a state adopts it. In a request for comment published in January 2024, the association counted about 21 states that had adopted the model rule or provided similar relief, and proposed to update the model so that it matches the federal statute, for instance by moving its presumption of control from 20% to 25%. Elsewhere, the answer depends on that state's own statute, on a different exemption, or on registration.
The cost of getting this wrong is not only a regulatory matter. In many jurisdictions a fee agreement made by an intermediary who needed a registration or a licence and did not have one can be difficult or impossible to enforce, which means the advisor's whole success fee rests on the answer. Outside the United States the same question exists under different rules, and the test, the exemptions and the regulator differ in each country.
## What goes in an M&A engagement letter?
An M&A engagement letter sets out the scope of the mandate, its exclusivity and term, a retainer paid during the work, a success fee paid at closing, the definition of the transaction value the fee is computed on, and a tail period that protects the fee after the mandate ends. It is the advisor's only claim to payment, so it is signed before any buyer is approached.
In outline, the retainer is a fixed monthly or milestone payment that covers part of the advisor's cost and shows that the client is committed; it is often credited against the success fee. The success fee is contingent on closing and is usually a percentage of transaction value, frequently with a minimum amount. How each is collected and accounted for is a subject of its own; what matters for someone entering the profession is knowing the clauses that cause disputes:
- **Transaction value.** Whether it includes debt assumed by the buyer, deferred payments, earn-outs, rollover equity and consideration paid for real estate or consulting agreements held outside the company.
- **When contingent consideration is paid for.** At closing on its full nominal amount, or as and when the seller actually receives it.
- **The covered transactions.** A sale of shares, a sale of assets, a merger, a minority investment, a refinancing that replaces the sale.
- **Tail.** The period after termination during which a deal with a buyer contacted under the mandate still earns the fee.
- **Expenses, indemnity and termination.** Which costs are reimbursed, what the client indemnifies, and how either party ends the mandate.
In the United States, an advisor relying on the federal exemption should also make sure the letter does not give it authority to bind the client or to handle the purchase price, since both would fall among the excluded activities.
## How do you build deal flow as a new M&A advisor?
A new M&A advisor builds deal flow from three sources: the professionals who hear first that an owner is thinking of selling, direct contact with owners in a sector the advisor knows, and buyers who need help finding targets. Referrals from accountants, lawyers, wealth managers and bankers are the most productive source in the lower and middle market, because an owner's first conversation about selling is usually with one of them.
Direct origination works when it is narrow: an advisor who knows one industry, its buyers and its valuation logic can write to two hundred owners with something specific to say, and each closed deal leaves a list of losing bidders who are the audience for the next mandate. Referral relationships are earned by being useful before there is a deal: a free and honest opinion of value for a client who is five years from selling, a view on what buyers pay in a sector, an introduction in the other direction. Any fee paid to a referrer needs care. A share of a transaction-based fee paid to a person who is neither registered nor exempt can raise the same securities-law question as the advisor's own fee, and professional rules may restrict what an accountant or a lawyer can accept, so the arrangement is checked with counsel and put in writing.
Buy-side work is the third route and often the first paid one. Acquirers and investors will pay a newcomer a modest retainer for a disciplined search in a sector, long before a seller entrusts the same newcomer with the sale of a life's work.
## What does a realistic first pipeline look like?
A realistic pipeline is a funnel in which most contacts lead nowhere: in the illustrative year below, 400 owners approached produce six signed mandates and three closings. The numbers are assumptions chosen to show the mechanics, not market statistics, and each advisor should replace them with their own.
| Stage | Count | Share of previous stage |
| --- | --- | --- |
| Owners approached, directly or by referral | 400 | — |
| First conversations held | 48 | 12.0% |
| Pitches made to an owner | 16 | 33.3% |
| Engagement letters signed | 6 | 37.5% |
| Letters of intent signed with a buyer | 4 | 66.7% |
| **Transactions closed** | **3** | **75.0%** |
Read from the bottom, the table says that one closing takes about 133 approaches, and that half of the signed mandates never pay a success fee. Deals fail for reasons no advisor controls, from a buyer's financing to an owner's change of mind. That is why retainers exist, and why a pipeline with a single mandate is a bet, not a business.
The calendar matters as much as the counts. If winning a first mandate takes three months and a sale process takes nine, the first success fee arrives about a year after the first approach, under these assumptions. Until then the practice lives on retainers and savings. Six mandates paying a retainer of $5,000 a month bring in $30,000 a month while all six are running, which covers costs for a small firm but is not the reason anyone enters the profession.
## How is a declining-percentage success fee computed?
A declining-percentage fee applies a high rate to the first slice of transaction value and lower rates to each further slice, so the fee rises with the price while the effective percentage falls. The best-known version is the Lehman formula, which steps down from 5% on the first million dollars to 1% above four million; advisors in the lower and middle market use their own scales with wider slices, and usually add a minimum fee.
Take an illustrative scale: 5% on the first $2 million of transaction value, 4% on the part from $2 million to $5 million, 3% on the part from $5 million to $10 million and 2% above $10 million, with a minimum fee of $150,000. On a $9 million sale the fee is $100,000 on the first slice, $120,000 on the second and $120,000 on the $4 million that falls in the third, or $340,000 in total. On a $2.5 million sale the scale gives only $120,000, so the minimum of $150,000 applies.

Illustrative scale, not a market rate. Retainers, expenses and any credit against the fee are not included.
Now apply the scale to the pipeline. The three closings are sales at $4 million, $9 million and $18 million of transaction value. Every mandate pays a retainer of $5,000 a month, credited against the success fee; the three that close run nine months each, and the three that do not are ended after six months.
| Mandate | Success fee | Retainers paid | Due at closing |
| --- | --- | --- | --- |
| Sale at $4 million | $180,000 | $45,000 | $135,000 |
| Sale at $9 million | $340,000 | $45,000 | $295,000 |
| Sale at $18 million | $530,000 | $45,000 | $485,000 |
| Three mandates that did not close | — | $90,000 | — |
| **Year total** | **$1,050,000** | **$225,000** | **$915,000** |
Revenue for the year is $1,140,000: the $915,000 collected at the three closings plus the $225,000 of retainers, or equally the $1,050,000 of success fees plus the $90,000 of retainers kept on the mandates that failed. The success fees average 3.39% of the $31 million of combined transaction value, and retainers supply 19.7% of the revenue. Almost half of the year's income comes from the largest transaction alone.
Success fees are often shared, with a co-advisor who brought the buyer, a sector specialist or a senior colleague working under a separate agreement. Where one fee has to be divided among several parties, a payment router is one way to do it: Shaka is such a router, in which each party's share is set as a percentage and can be signed by each recipient before the client pays, the client pays once, and every party is paid their share at the same moment, without the router holding the funds. If the $340,000 fee above were shared 70/30 with a co-advisor, the two shares would be $238,000 and $102,000. Whether a given person may lawfully receive a share of a transaction-based fee remains a question for the securities rules described earlier.
## Should you join a firm or start your own practice?
Most M&A advisors should spend their first years inside an established firm, because the craft is learned on live transactions and sellers ask for a track record before they sign. Starting alone is realistic for someone who already has closed deals, a sector network or an owner's credibility, and enough savings to wait about a year for a first success fee.
Joining a firm gives a newcomer four things that are hard to assemble alone: supervised repetition of the full process, templates and data that took years to build, a name that reassures sellers, and, in the United States, a compliance structure, whether that is a registered broker-dealer or counsel's written analysis of the exemption.
Starting a practice requires the reverse inventory. Before the first approach, an independent advisor needs a defined sector and deal size, an engagement letter drafted by a lawyer who knows the profession, a written conclusion on securities and licensing rules for the relevant country and states, professional liability insurance where it is available, and a list of the specialists, such as tax advisors, transaction lawyers and diligence accountants, to bring into each mandate. A common middle path is to affiliate with an existing boutique as an independent originator, bringing mandates and sharing the fee with the team that executes them.
