M&A Advisory Fees in the GCC: How Advisors Charge

A clear explanation of how M&A advisors charge for their services in the GCC: retainers, success fees, minimum fees, and what business owners should expect when engaging an advisor.

One of the first questions business owners ask when considering an M&A advisor is how the advisor charges. This guide explains the standard fee structures in the GCC market and what to expect.

The two components of M&A advisory fees

Most M&A advisory engagements in the GCC are structured around two fee components.

The retainer. A fixed fee, typically paid monthly or at defined milestones, that compensates the advisor for the substantial work involved in preparing a business and running a transaction process. This work (building the information memorandum, the financial model, the data room, and managing the process) is significant and happens regardless of whether a transaction ultimately closes.

The success fee. A percentage of the transaction value, paid only when the deal closes. This is the primary form of advisor compensation and aligns the advisor's incentives directly with the client's outcome: the advisor earns more when the transaction closes at a higher value.

How the success fee is set

The success fee is usually a percentage of the transaction value. As a rule, the percentage falls as the transaction gets larger, and it moves with the complexity of the deal and the work involved: smaller and more complex transactions tend to carry higher percentages because the work is proportionally greater.

Some mandates use a single percentage; others use a scale, with a higher rate on value achieved above an agreed level to reward a stronger outcome. Because practice varies widely, the right reference point is the specific proposal in front of you and exactly how it is calculated.

Why advisors charge a retainer

Some business owners question why they should pay a retainer when there is also a success fee. The reason is that preparing a business for sale and running a transaction process involves months of substantial work (financial analysis, document preparation, buyer research, and process management) that happens before any transaction is certain.

A retainer ensures the advisor is compensated for this work and is committed to the engagement. It also signals that the client is serious. Without one, an advisor has less reason to prioritise an engagement that may not close.

What about minimum fees?

Many engagements include a minimum success fee: a floor that ensures the advisor is adequately compensated even if the transaction value comes in lower than expected. This is standard practice and protects the advisor against a scenario where significant work produces a small transaction.

How fees are structured in a mandate

The fee arrangement is documented in a mandate letter or engagement agreement, which specifies: the retainer amount and payment schedule, the success fee percentage and how it is calculated, any minimum fee, the definition of transaction value on which the fee is based, and the circumstances under which fees are payable.

It is important to understand exactly how the success fee is calculated: what is included in transaction value, how earn-outs and deferred consideration are treated, and when the fee becomes payable.

Are M&A advisory fees negotiable?

Fee structures are generally negotiable, particularly the balance between retainer and success fee. A business confident in its transaction may prefer a lower retainer and higher success fee. The key is ensuring the structure aligns the advisor's incentives with a successful outcome at the highest value.

What you are paying for

It is worth remembering what M&A advisory fees pay for: the difference between a well-executed transaction and a poorly executed one. Judge the fee against what the advisor will actually deliver: the valuation work, the terms, the risks addressed and the likelihood of closing.
