Buy-Side Advisory

Buy-side advisory is the work an investment bank or M&A boutique does for a buyer: finding and screening targets, making the approach, valuing the business, structuring the offer, running diligence and negotiating the terms to signing. The seller's adviser runs the process; the buyer's adviser gets the buyer through it at the right price — or tells it to stop.

Also known as
Buy-side adviser, Buy-side M&A advisory, Acquisition advisory
Used at
acquisitions by companies without a corporate development team, by funds on a competitive process, and by any buyer of a licensed fintech that has not bought one before
Binding
an engagement letter with a retainer, a success fee and a scope; the adviser owes the buyer its advice, not a result
Typical fee
a monthly retainer of €10,000–50,000 credited against a success fee of 1–2% of the deal value for mid-market deals (higher percentages below €20m, lower above €200m); the fee is paid on completion, which is why the adviser's incentive is to close and the buyer's job is to keep it honest
Typical scope
target search and screening, valuation and offer strategy, coordination of the diligence workstreams, negotiation of heads of terms and the sale agreement alongside the lawyers, regulatory strategy for a licensed target, and financing if needed
Parties
the buyer, its adviser, the target and its sell-side adviser, the diligence providers the buy-side adviser coordinates

How buy-side advisory works in practice

A buyer that wants to enter payments, or add a lending capability, or buy a competitor, engages an adviser. In a proprietary search the adviser builds a list of targets, ranks them against the buyer's criteria, approaches the ones the buyer chooses and turns interest into a negotiation. In an auction the adviser reads the process letter, values the target, advises on the indicative offer, coordinates the second-round diligence — accountants, lawyers, commercial and technology specialists — and drafts the binding offer and its mark-up strategy. Throughout, it tells the buyer what the business is worth, what the seller will accept, where the risks are and when to walk.

The value of the adviser is judgement and process. A buyer bidding alone in an auction pays what the seller's adviser can extract; a buyer with an adviser that has seen thirty payments deals knows what the market pays, what the diligence will find and which of the seller's terms are negotiable. For a licensed target the adviser's regulatory experience — what the regulator will ask, how long it takes, what conditions it imposes — is often the reason to hire one.

The conflict is the success fee: the adviser is paid if the deal closes, not if it was a good deal. Buyers manage this by retaining the adviser through the diligence and by making the walk-away recommendation a part of the scope — and by remembering that the best advice they will get is sometimes "don't".

Example

A software group with no deal team wants a payments capability and engages a boutique on a €25,000 monthly retainer and a 1.5% success fee. The adviser screens 40 payment facilitators and licensed providers, approaches six, and turns two into negotiations. For the preferred target — €5m of EBITDA, a licence, founders who will stay — it values the business at €42–50m, advises an opening offer of €44m, coordinates €280,000 of diligence across four providers, negotiates the heads at €48m with an earn-out of €4m of it, and manages the regulatory application with the buyer's lawyers. Signing is seven months after engagement; the fee is €720,000 less the €175,000 of retainers. The buyer's alternative — bidding on its own in the auction the other target ran — would have cost it more than the fee, in the price alone.

Common mistakes

- Hiring the adviser for the auction and not for the search, so the targets are whatever comes to market. - A success fee with no retainer, which buys an adviser that needs the deal to close. - Letting the adviser coordinate diligence and not read it. - No regulatory workstream in the adviser's scope for a licensed target. - Treating the adviser's valuation as the price rather than the ceiling.
