How to Value an Agricultural Spraying Business in 2026

Aerial application — what everyone outside the industry still calls "crop dusting" — is one of the most specialized businesses I value. It combines aviation, agronomy, and a brutal seasonal calendar. The operating business generates real cash, but the value is inseparable from the fleet, the pilot, the FAA certifications, and the customer relationships built over decades.

There are roughly 1,560 aerial application operators in the U.S. today, according to the National Agricultural Aviation Association, and that number has been slowly declining as solo operators retire and larger regional outfits consolidate. If you're running one of those operations and thinking about selling, here's how buyers actually price these businesses in 2026.

The Multiple: 2-4x SDE

Aerial application businesses trade at 2.0-4.0x SDE on the operating business, plus the separately-valued fleet. That's a wide band, and where you land depends almost entirely on whether the business can run without the selling pilot-owner.

A solo operator with one plane, one pilot (themselves), and 30 loyal farm customers is realistically a 2.0-2.5x SDE business. Buyers know that when the owner walks, there's nothing left but a hangar and an airplane. The goodwill has legs.

A multi-plane operation with 2-4 pilots, a dedicated loader crew, a mix manager, and written customer contracts can push to 3.5-4.0x SDE because it genuinely survives an ownership change. The business has become an enterprise rather than a one-person show.

On top of that multiple, the aircraft themselves are valued separately at fair market value. An Air Tractor AT-802A — the workhorse of the industry — sells used for $1.3M-$1.8M depending on hours and configuration. A newer Thrush 510G might be $900K-$1.2M. Buyers pay for the business and assume or buy the aircraft separately, which means the headline SDE multiple only tells you half the story.

FAA Part 137 and Pilot Certification

Every aerial application business operates under FAA Part 137certification. The certificate is tied to the operating entity, which means it can transfer in a stock sale but requires a new application in an asset sale. In practice, most aerial application deals are structured as stock sales specifically to avoid the 6-12 month delay of getting a new Part 137 certificate reissued.

The pilots themselves are the other constraint. A qualified ag pilot needs a commercial certificate, Part 137 training, specific endorsements for the aircraft flown, and realistically 500-1,000 hours of ag-specific flight time before they're productive. The national shortage of experienced ag pilots has become acute — I've seen operators turn down $300K of work in 2025 because they simply could not hire a second pilot at any price.

What this means for valuation: if your business depends on you flying the plane, your buyer pool shrinks dramatically. There are only two realistic buyers for a pilot-owner-dependent operation — another working ag pilot looking to buy their own outfit, or a regional operator who happens to have an extra pilot on the bench. Both groups pay at the low end of the range.

If you can hand the business to a buyer with two or three employed pilots staying on through transition, you open up the deal to regional consolidators and financial buyers, and you earn the premium end of the multiple.

Seasonality and Revenue Quality

The seasonal curve of this business is brutal and it shapes everything about how buyers underwrite it. In corn and soybean country, 70-85% of annual revenue is generated in roughly 12 weeks between mid-June and early September — fungicide applications on corn, insecticide on soybeans, late-season herbicide where aerial is the only option because the crop is too tall for ground rigs.

That compression means a single bad weather month can destroy a year's earnings, and a single aircraft going down for maintenance during peak season is a catastrophic event. Buyers price this risk in. They'll look at a 5-year rolling average of SDE, not the most recent year, and they'll ask detailed questions about weather-impacted seasons.

Operations with more diversified seasonal work earn a meaningful premium. That might include spring pre-emergent herbicide, cover crop seeding in the fall, rice-growing region work (which runs on a different calendar), forestry spraying, mosquito abatement contracts with counties, or pasture and rangeland treatment. Every month of calendar diversification you can show stabilizes the revenue and pushes the multiple up.

The Aircraft Fleet and Hidden Capex

The most common mistake sellers make is overvaluing their own fleet. An Air Tractor that you bought new for $1.6M in 2018 is not worth $1.6M today, regardless of how well you've maintained it. Used ag aircraft values are tracked closely by a handful of brokers — Lane Aviation, Farm Air, Valley Air Crafts — and their comparable sales data is what your buyer will reference.

The bigger issue is engine and airframe time. A PT6A-65AG turbine (the engine on most Air Tractor 802s) goes to hot section inspection at 1,750 hours and full overhaul at 3,500 hours. A hot section runs $75K-$120K. A full overhaul is $400K-$550K. If your aircraft is at 3,200 hours on the engine, the buyer is going to subtract $400K from the aircraft value because they're staring at an overhaul in the next two seasons.

Airframe hours, prop inspections, GPS and flow control system upgrades, and spray system maintenance all factor in the same way. Get current on every inspection and overhaul before you go to market. It's cheaper to do the work yourself than to take the discount from a buyer's adjusted offer.

Customer Concentration and Contracts

Most ag spraying businesses I look at have handshake relationships with farmers and ag retailers going back 15-30 years. That loyalty is real, and it's part of what buyers are paying for — but it's also completely uncontractual and transferable only if the selling owner vouches for the new operator.

The business structures that earn premium multiples have formal relationships with ag retailers — Nutrien Ag Solutions, Helena Agri-Enterprises, Wilbur-Ellis, GROWMARK / FS, regional co-ops. When you're the preferred aerial applicator for a big retailer, they route work to you, handle the customer billing, and provide a pipeline of acres that doesn't depend on any individual farmer relationship. Those accounts transfer much more reliably in a sale.

Concentration matters in both directions. A business with one retailer driving 50% of revenue is at concentration risk — lose that relationship and half the business is gone. The sweet spot is 3-5 retailer relationships and 20-40 direct farm accounts, with no single customer over 20% of revenue.

What Drives Value Up and Down

Drone integration. The operators who've added heavy-lift spray drones for small or awkward fields have created a hybrid offering that's genuinely differentiated. Drones don't replace fixed-wing for broadacre work, but they capture jobs that traditional aerial can't — specialty crops, steep vineyards, small organic fields near residential areas. Buyers in 2026 pay for this diversification.

Hangar and base real estate. Like other aviation businesses, a privately-owned hangar with fuel storage, loading pad, chemical mix area, and strip access is a separate asset worth $300K-$1.5M depending on size and location. Don't let the buyer bundle it into the business sale for free.

Chemical handling compliance. EPA and state regulators have gotten significantly more aggressive about aerial drift, pollinator protection, and mix/load site containment. An operation with documented compliance — closed loading systems, proper secondary containment, updated SOPs — is worth more than one with cut corners. Noncompliance shows up as environmental liability in due diligence and can kill deals.

Insurance history. Aviation insurance for ag operators is expensive and underwriters are strict. A clean loss history helps the buyer assume the policy at reasonable rates. A history of incidents can double the insurance premium for the new owner and will reduce what they'll pay.

The Bottom Line

An aerial application business is worth 2-4x SDE on operations, plus the separately-valued fleet, plus real estate if you own it. The sellers who maximize their exit are the ones who've built a real operation — multiple pilots, retailer relationships, calendar diversification, and current maintenance — rather than a pilot-owner job with an airplane attached. If you're 2-3 years from retirement, hire and train a second pilot now. That single decision is worth more to your valuation than anything else you can do.
