What does it do?
Butler National is a growth-stage business that earns money by performing specialized engineering modifications on aircraft and managing a casino in Dodge City, Kansas. The aerospace segment accounts for the majority of revenue, charging fees to design, manufacture, and install custom systems like sensors or cameras on business jets for government and corporate clients. In its gaming segment, it manages the Boot Hill Casino and Resort, taking a management fee based on a percentage of gaming revenues while operating on-site dining and entertainment. This hybrid model uses the steady, local monopoly cash flow of the casino to fund the capital-intensive engineering developments in the aerospace division.
Where does revenue come from?
The majority of revenue now comes from aerospace modifications and defense electronics, which together brought in $60.6 million last year. Aerospace Products accounts for 62% of the mix and is growing at 33% annually, while Professional Services (Gaming) contributes 38% at $37.4 million. While the casino revenue is concentrated in Kansas, the aerospace segment serves a global market of aircraft operators and government agencies requiring special mission capabilities.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Butler National serves government defense agencies, international aircraft operators, and roughly 500 slot machine players at its Kansas casino. The aerospace segment relies on a record $47.1 million backlog of firm and pending orders from clients who own Learjet, Challenger, and King Air aircraft. In the professional services segment, the company manages the DraftKings branded sportsbook and 15 table games at Boot Hill Casino, where revenue recently dipped to $26.7 million due to regional economic pressures. While the aerospace client base is small and concentrated in high-value contracts, the gaming business serves thousands of individual retail customers annually.
What gives it staying power?
Butler National has staying power because it owns proprietary Supplemental Type Certificates (STCs) that are legally required to modify specific aircraft models. These certifications act as a regulatory barrier, as any competitor wanting to offer the same modification would have to spend years on independent engineering and FAA testing.
Where is it headed?
The company is headed toward becoming a dominant provider of "Special Mission" integration for larger jet platforms like the Bombardier Challenger. Management is investing heavily in new product development to move up the value chain from simple structural changes to complex electronic system integration. This shift is intended to drive higher profit margins as the company converts its record backlog into completed aircraft deliveries.
Revenue and earnings are accelerating sharply as the business pivots toward higher-margin aerospace work. Sales grew 17% to $98 million in fiscal 2026, but net income jumped 75% to $21.9 million. This massive earnings jump proves the company is reaching a scale where its fixed engineering costs are spread across much larger, more profitable contracts.
Cash generation is exceptional, with free cash flow of $20 million tracking closely with record net income. The company converted nearly 20% of its total revenue into free cash flow last year, which is rare for an industrial business. This cash allowed management to aggressively repurchase 3.3 million shares, shrinking the share count and boosting the value of remaining holdings.
The balance sheet is in its strongest position in years, with stockholders' equity growing 26% to $82 million. Long-term liabilities fell 16% to $28.4 million, and the company carries a conservative debt-to-equity ratio of 0.41x. This low leverage gives the company significant room to fund new aircraft modification hangars or product developments without needing external debt.
Butler National is a financially elite industrial business that is currently self-funding its own rapid expansion through high-margin service revenue.
The aerospace segment is firing on all cylinders, growing revenue by 33% to $60.6 million and driving a record $47.1 million backlog. This performance is the result of years of investment in FAA certifications that are now being converted into high-margin sales of modification kits and special mission electronics.
Regional economic pressure in Kansas is weighing on the gaming segment, where casino revenue fell 5% to $26.7 million. While this segment provides steady cash, a prolonged downturn in the local agricultural economy could limit the "cushion" of cash available for aerospace investment if modifications ever hit a cyclical lull.
The aerospace and defense market is currently valued at roughly $850 billion and is expected to reach $1 trillion by 2028. This is a highly attractive industry because pricing power is structural due to the extreme safety and regulatory requirements that govern aircraft modifications. Butler National operates as a niche leader in the specialized modification market, where it holds a significant growth runway as global demand for intelligence, surveillance, and reconnaissance (ISR) aircraft continues to outpace traditional defense spending.
The competitive dynamic in aircraft modification is rationally structured because the costs of entering the market are prohibitive. Barriers to entry are high because a company cannot modify a plane without owning or licensing the specific engineering designs approved by the FAA. This prevents a race to the bottom on price and allows established players with existing certifications to maintain healthy margins.
Competitors range from massive defense contractors to specialized private shops. Sierra Nevada Corporation is the most dangerous threat because it has the scale to bid on large-scale government fleet modifications that Butler National might struggle to fulfill alone. Other rivals like StandardAero and Duncan Aviation compete for the same business jet customers, but they often focus on more routine maintenance rather than the deep structural and electronic modifications that are Butler's specialty.
Butler National is gaining share in the special mission niche, evidenced by its 33% segment growth and record backlog.
The primary source of protection is intangible assets in the form of over 400 FAA-approved Supplemental Type Certificates (STCs) that give the company the exclusive right to perform specific modifications. These certificates are the result of decades of proprietary engineering and flight testing, making them nearly impossible for a new entrant to replicate quickly.
The company's 18.5% ROIC and 51% gross margins confirm that these assets provide real pricing power. These numbers prove that Butler National is not just a service shop but a high-value engineering firm protected by its own proprietary designs. The combination of rising backlog and steady margins suggests that customers are willing to pay a premium for Butler's specific, certified solutions.
The Narrow rating reflects that while the STCs provide excellent protection, the company’s small scale makes it vulnerable if a larger rival decides to aggressively target its specific aircraft niches. A Narrow rating is appropriate because the moat is highly effective in its small territory but has not yet proven it can scale to much larger aircraft platforms.
The moat is strengthening as the company secures new certifications for modern jet platforms like the Bombardier Challenger 605. This expands the "territory" the company effectively owns, making its competitive position more durable over the next decade.
Delivered 75% net income growth and 17% revenue growth in FY2026.
Repurchased 3.3 million shares and reduced long-term debt by 16% in FY2026.
Executive Chairman Jeffrey Yowell and management have maintained a strict no-dilution policy.
Capital Allocation Track Record
Management is delivering exceptional results by focusing on high-margin engineering work while treating shareholder capital with extreme discipline. Interim CEO Adam Brett Sefchick has overseen a record year where operating income surged 69%, proving that the team can execute even during a leadership transition. Their decision to avoid shareholder dilution while shrinking the share count by over 3 million shares shows a level of alignment with owners that is rarely seen in companies of this size.
The primary risk is the current search for a permanent CEO, which creates some uncertainty regarding long-term strategic continuity. However, the presence of Executive Chairman Jeffrey Yowell provides a bridge of experience, and the deep bench of engineering talent at subsidiaries like Avcon suggests the technical execution is not dependent on a single individual. The company's record $47 million backlog provides a clear "to-do list" that the current team is already successfully converting into profit.
We expect revenue to grow from $0.1B in FY2026 to $0.140B in FY2031 (~7% CAGR), with EPS growing from $0.34 to $0.54 (~10% CAGR). Demand for specialized aircraft modifications like freighter conversions and radar integration provides a steady backlog of high-value contracts. Specialized engineering expertise allows the company to command premium pricing while spreading fixed facility costs over more modification projects. EPS grows faster than revenue because profit margins are increasing as the company takes on more complex, higher-margin aerospace work. Operating margin expected to reach ~32% by FY2031.
Record backlog conversion drives sustained double-digit revenue growth. Converting the existing $47 million backlog provides high visibility into aerospace revenue for the next 24 months.
New FAA certifications open high-value special mission markets. Each new Supplemental Type Certificate for platforms like the Bombardier Challenger expands the addressable market for high-margin modifications.
Continued share repurchases amplify per-share earnings growth. Using strong free cash flow to shrink the share count makes each remaining share significantly more valuable as net income rises.
Leadership transition delays execution of the record backlog. A failure to find a permanent CEO or a loss of key engineering talent could slow down the modification timeline.
Slowdown in regional agricultural economy hurts casino gaming. Weakness in Western Kansas could continue to weigh on the professional services segment, reducing the cash available for aerospace investment.
Large defense contractors target Butler's niche modification certificates. If a major player like Sierra Nevada aggressively pursues the same jet platforms, it could compress margins in the aerospace segment.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Normalized P/E approach based on mid-cycle earning power rather than the current record results. This framework fits Butler National because the company just saw a massive jump in profit margins (from 17% to 33%) and net income. Normalizing—or smoothing—these numbers ensures we do not overpay for what might be a temporary peak in the aerospace contract cycle.
A mid-cycle EPS of $0.24 multiplied by a 24x multiple gives a per-share fair value of $5.75. A 24x multiple (investors paying $24 for every $1 of yearly profit) sits between aerospace engineering peers like Ducommun (18x) and Kratos (32x). We use a normalized $0.24 EPS instead of the projected $0.42 to stay conservative while the company navigates a major leadership change.
A sum-of-the-parts (SOTP) cross-check produces a fair value of $5.85 — within 2% of our primary answer, confirming the result. We valued the Aerospace business at $303 million (5.0x its yearly sales) and the Casino business at $67 million (1.8x its yearly sales). After adding $10 million in net cash and dividing by 64.9 million shares, the result is nearly identical to our normalized earnings approach, which gives us high confidence that $5.75 is a fair and grounded price for the stock.
We're assuming a mid-cycle earning power of $0.24 per share. This is the average profit the company produced over the last three years, which smooths out the massive 75% jump seen in 2026 and ensures we aren't valuing the company based on a single, potentially lucky year.
We're assuming the Aerospace segment can sustain a 33% operating margin through 2027. This profit level is nearly double the company's historical average and is supported by a record $47 million backlog—work that is already signed and waiting to be completed—which provides clear visibility for the next 18 months of profit.
We're assuming a 24x normalized P/E multiple for the consolidated business. This price-to-earnings ratio (what investors pay for each $1 of profit) reflects a blend between the high-value aerospace engineering business and the slower-growing casino management segment.
The biggest risk is that the recent jump in profit margins is a temporary peak caused by a few high-priced aerospace contracts. This would push the fair value down toward $3.50 as the company's "earning power" (how much it can reliably make) is exposed as being lower than the recent record results. Watch for any dip in the Aerospace segment's operating margin below 25% in the next two quarterly reports as an early warning sign.
Bear case ($4): Aerospace profit margins revert to the 15% to 18% historical range as one-time "special mission" contracts conclude; or The record $47 million backlog conversion stalls during the CEO transition, causing a two-quarter revenue miss.
Bull case ($9): Aerospace grows to 75% of total revenue, triggering a valuation "rerating" where investors pay a premium defense-contractor multiple; or New FAA certifications for Bombardier and Learjet platforms lead to a 50% year-over-year jump in special mission modifications.
