How Fixed Base Operators Are Valued

A fixed base operator is not one business. It is three or four businesses and a piece of real estate sharing an address, a fuel farm, and a single set of books. Valuing it as one company, on one multiple, is where most FBO valuations go wrong, and it is why buyer and seller so often arrive at numbers that are not close.

Start by separating the revenue streams

The streams behave differently, carry different risk, and do not deserve the same multiple.

Fuel is a margin business, not a revenue business

Gallons and gross fuel revenue are the numbers most often quoted and the least informative. What matters is margin per gallon, and how much of it is durable. A location with high volume and thin contract margin can generate less profit than a smaller operation with strong retail share. Self serve installations shift both volume and margin. Fuel is also the stream most exposed to a second FBO on the field or to a sponsor decision on fuel flowage.

Hangar revenue is real estate wearing a business costume

This is the part buyers most often underprice and sellers most often fold into an enterprise multiple where it does not belong. Hangar rent is contracted, occupancy at most fields is high because supply is constrained, and the stream behaves like property income. It should be analyzed as property income, on the underlying leasehold, and then reconciled with the enterprise analysis rather than blended into it.

The GA hangar rent index exists in part for this reason. Underwriting hangar revenue at an FBO requires a view on where market rent sits and where it has been trending, and most FBO models simply carry forward the seller's current schedule.

The operating agreement is frequently the largest single asset

An FBO does not own its position on the field. It holds it under an agreement with the airport sponsor, and that agreement determines almost everything about the durability of the earnings a buyer is purchasing.

• Remaining term. The same wasting asset problem that governs hangars governs the FBO position. Earnings that run out in nine years are not worth a perpetuity multiple.
• Renewal mechanics. Whether extension is at the sponsor's discretion, and on what rent.
• Exclusivity, or the absence of it. Whether the sponsor may admit a second operator, and under what conditions.
• Minimum standards. Required hours, staffing, equipment, and capital investment obligations that a buyer inherits.
• Transferability and consent. Whether the agreement assigns on a sale, whether the sponsor's consent may be withheld, and what conditions the sponsor may attach to it.
• Fuel flowage and revenue sharing. What the sponsor takes off the top, and whether it can be adjusted.

Why EBITDA multiples get misapplied

FBO transactions are commonly discussed in terms of an EBITDA multiple, and comparables circulate in the market. The practice is not wrong, but it is applied carelessly more often than not.

A multiple imported from a transaction at a different field carries that field's traffic, that agreement's remaining term, and that operator's revenue mix embedded in it. Applying it to a target with nine years remaining and a thin contract fuel margin is not comparison, it is substitution. Adjustments have to be made explicit: term, exclusivity, mix, capital obligations, and the condition of the improvements.

There is also a definitional problem. Reported EBITDA at owner operated FBOs frequently needs normalizing for owner compensation, related party rent, deferred maintenance, and capital expenditure that has been postponed. Normalizing adjustments are where most of the disagreement in an FBO negotiation actually lives.

Separating enterprise value from the leasehold

At closing, a single price gets agreed. Then it has to be allocated, and buyer and seller have opposing tax incentives on where it lands. An allocation that is simply negotiated, without a supportable derivation, is exposed on both sides.

The defensible approach values each component on its own basis and reconciles to the transaction price:

1. Value the leasehold improvements as property, on the remaining ground lease term, with reversion modeled.
2. Value the operating business on normalized earnings, adjusted for the remaining agreement term and its transfer conditions.
3. Identify tangible personal property separately: fuel trucks, tugs, ground support equipment, shop equipment.
4. Test what remains against the intangible position, and be honest about how much of it is really the operating agreement rather than goodwill.

What buy side diligence should test

• Read the executed agreement, not the summary. Consent, exclusivity, and minimum standards are where surprises live.
• Reconcile the rent roll to the leases. Not to the offering memorandum.
• Separate contract from retail fuel and test margin durability, not gallon count.
• Ask who else could come onto the field, and whether the sponsor has signaled anything.
• Inspect the improvements against the obligations the agreement imposes, since deferred capital transfers with the business.
• Screen the field for firefighting foam history. Contamination is a live issue at fuel and fire training locations and can impair a later exit. The PFAS and AFFF exposure map is a starting point.
• Model the terminal value honestly. If the agreement expires before the hold period ends, the exit assumption is the entire deal.

Most disputed FBO valuations come down to two questions: how much of the earnings is really hangar rent, and how long does the operating agreement actually run. Answer those two carefully and the rest of the analysis tends to fall into place.
