How to Value an FBO (Fixed Base Operator) in 2026

FBOs are one of the most misunderstood assets in private aviation. From the outside, they look like glorified gas stations with a lobby. In reality, a well-run FBO at a busy reliever airport can generate $3-8M in EBITDA and sell to Signature Aviation or Atlantic Aviation for 10x or more. I've walked sellers through FBO transactions where the final number was double what a generic business broker initially quoted, because FBO value lives in places most brokers don't understand.

Here's how FBO valuation actually works in 2026, and what drives the spread between a $4M FBO and a $40M FBO at airports that look identical on a map.

What You're Actually Selling

An FBO is a bundle of four revenue streams sitting on top of a ground lease with the airport sponsor. Getting the valuation right means understanding how each piece contributes and how buyers weight them.

Fuel sales are the headline number but rarely the highest-margin piece. A mid-size FBO pumping 3-5 million gallons of Jet-A per year generates impressive top-line revenue, but the margin is a spread — typically $0.80 to $1.80 per gallon after cost of goods, fuel farm operating costs, and into-plane service. Buyers care far less about gross fuel revenue than they do about the per-gallon margin and the stability of the volume.

Hangar rent and tie-downs are the quietly beautiful part of an FBO P&L. Hangar revenue is annuity-like, high-margin (70-85% after the roof is paid for), and tied to long-term tenants who rarely move. An FBO with 150,000 square feet of hangar space leased at $1.50-$2.50 per square foot per month is printing money. I've seen buyers pay 12-15x EBITDA specifically for hangar-heavy FBOs because it's the closest thing in aviation to a triple-net real estate cash flow.

Ground handling and ramp services — lav service, GPU, potable water, de-ice, tow — are the sticky customer service layer that keeps jets coming back. Margins are modest (20-35%) but the revenue is recurring for based aircraft and drives fuel sales for transients.

Ancillary revenue — car rental commissions, catering markups, crew cars, pilot lounge vending, flight planning, oxygen service — rounds out the P&L. It's small individually but collectively meaningful.

The Multiples: What FBOs Actually Trade For

FBO multiples span a wider range than almost any other aviation asset because location and lease term dominate the calculus. Our transaction database and published benchmarks point to these ranges:

• Single-location, short lease (under 10 years remaining): 4-6x EBITDA. The lease cliff terrifies buyers.
• Single-location, strong lease (20+ years): 7-9x EBITDA for a well-run independent.
• Strategic location for a consolidator: 9-12x EBITDA. Signature, Atlantic, Million Air, and Modern Aviation compete hard for fill-in airports.
• Multi-location platform: 10-14x EBITDA. A chain of 3-5 FBOs in desirable markets trades at a platform premium.
• Hangar-heavy or land-banked FBOs: 12-16x EBITDA, where real estate value drives the math.

When Signature Aviation (owned by Blackstone, GIP, and Cascade after the 2021 take-private) buys a bolt-on, they're underwriting the five-year synergy — better fuel contracts, shared back office, corporate customer traffic. They'll pay up if the airport fills a geographic hole in the network. Atlantic Aviation (owned by KKR) operates the same playbook. Million Air and Modern Aviation are the next tier of active consolidators.

The Ground Lease Is Everything

I cannot overstate this: the single biggest variable in FBO valuation is the remaining term and terms of your ground lease with the airport sponsor. Two otherwise identical FBOs — same gallons, same hangar square footage, same EBITDA — can sell for wildly different numbers based solely on lease term.

Buyers underwrite against the lease like a bond. A 30-year lease with two 10-year options trades at a premium. A 15-year lease with no renewal is a warning. Anything under 10 years and institutional buyers start running. They've seen too many cases where the airport sponsor waited out the lease, issued a new RFP, and awarded the location to a competitor or built a municipal FBO.

If you own your FBO and your lease has less than 15 years remaining, the single highest-ROI thing you can do before selling is negotiate an extension. I've seen a lease extension from 12 years to 30 years add $8M to an FBO's sale price. The extension itself cost nothing except some legal fees and a modest rent bump.

Fuel Margin Quality and Volume Stability

Not all gallons are created equal. A sophisticated buyer will decompose your fuel volume into transient versus based-aircraft gallons, contract fuel versus retail, and Jet-A versus 100LL. Each bucket carries a different margin and a different risk profile.

Based-aircraft gallons are gold. A Gulfstream based in your hangar burning 40,000 gallons a year at retail is predictable, high-margin revenue that a buyer will capitalize at the full multiple. Transient retail gallons are also high margin but more volatile — weather, fuel price arbitrage, and competitive pricing at nearby fields all move the needle. Contract fuel gallons (Avfuel, World Fuel, Colt International programs) pay the lowest margin but drive volume.

Buyers will want to see three years of monthly gallon history broken out by category. If you can't produce that, fix your reporting now. The difference between a buyer assuming your gallons are 60% contract versus 30% contract can be worth $1.50 per gallon in margin, which on 4M gallons is $6M of annual EBITDA and tens of millions in enterprise value.

What Kills FBO Value

A second FBO on the field. When airport sponsors add a competing FBO, it almost always compresses margins. If your airport is rumored to be issuing an RFP for a second operator, sell before the announcement — not after.

Fuel farm environmental issues. Old underground tanks, documented spills, or missing environmental reports create diligence nightmares. Buyers will hold back 10-20% of the purchase price in escrow or walk entirely. Get a Phase I environmental done before going to market and address any findings.

Customer concentration. If 40% of your based aircraft revenue comes from one fractional program or one charter operator, that's a risk buyers price in heavily. See how customer concentration destroys business value for the mechanics.

Deferred capex. A 40-year-old terminal with a leaking roof, a fuel farm that needs tank replacement, or a ramp that needs re-paving all get deducted dollar-for-dollar from buyer offers. Get ahead of these before a buyer's engineering report does it for you.

How to Maximize Your FBO Value

Extend the lease. I'll say it again because it matters that much. Every year you add to the tail is worth real money.

Build hangar square footage. If you have land on your leasehold and unmet hangar demand, building a new box hangar is one of the highest-ROI investments in the industry. Hangar rent flows through at 80%+ margin and gets capitalized at the full FBO multiple.

Clean up the P&L. FBO owners notoriously run personal expenses through the business. Before going to market, work with a CPA to produce clean adjusted EBITDA with defensible add-backs. Buyers discount add-backs they can't verify.

Run a competitive process. The FBO buyer universe is small but intense. Signature, Atlantic, Million Air, Modern Aviation, Ross Aviation, Jet Aviation, and half a dozen private equity-backed platforms all hunt for the same deals. A banker who runs a real process will typically add 15-25% to the final number compared to a bilateral deal.

The Bottom Line

FBO valuation is fundamentally a real estate and strategic location exercise dressed up as an operating business. The best FBO sellers I've worked with spent 2-3 years before the sale extending their lease, building hangar capacity, and cleaning up their fuel margin reporting. They ended up selling at double-digit EBITDA multiples to Signature or Atlantic while their neighbors with identical gallons settled for 5-6x to a regional buyer. The gap is almost never about the airplanes on your ramp — it's about the paper behind the FBO.
