Butler National: The Engine Is Aerospace, Not the Casino
An aerospace quarter wearing a broad-growth costume
Butler National's fiscal Q1 2027 print looks like a clean beat: revenue up 53% to $30.8M, operating income up 59% to $7.4M, net income up 43% to $5.3M, and EPS of $0.08 versus $0.06 a year ago. But composition matters more than totals here. Essentially all of the growth came from a single segment. “This was led by a 92% increase in aerospace products revenue, which includes aircraft modifications, avionics and special mission electronics.” — Adam Sefchick, Executive or Senior Management · 2026-09-11 The Aircraft Modifications division alone rose 189%, to $16.3M from $5.6M, while Special Mission Electronics and various kit programs filled in the rest.
The other half of the company barely moved. Professional Services revenue rose 3% to $9.0M, and traditional gaming revenue — the Boot Hill casino floor — grew 6%. In other words, this is not a diversified industrial compounding a little everywhere; it is an aerospace story carrying a casino on its back. Segment-level operating margin has been climbing for years, and the call reported overall operating margin ticking up to 24% from 23%, with the aerospace segment holding roughly 25%.
The STC/kit flywheel is the genuine change
Here is what is actually new: management devoted most of the Q&A to explaining a business-model shift that reframes the whole aerospace segment. It starts with New STCs — FAA supplemental type certificates the company engineers and owns outright — then monetizes them through Kit sales shipped to qualified third-party installers rather than requiring every aircraft to occupy a company hangar. The top of the stack is mission systems integration, turning a structural modification into a fully functional mission system with workstations, power and communications.
STCs create intellectual property, kits allow us to scale that intellectual property and mission systems integration allows us to provide a higher value, more comprehensive solution to the customer. Together, those capabilities expand both the markets we can address and the value we can provide to our customers.
That is the difference between a labor-bound hangar business and a licensing-like, repeatable one — and the stock has re-rated accordingly. It also explains the record $51.1M backlog at July 31, 2026, nearly double the $28.2M the company cited back on the December 2022 call. Management paired this with the rebranding of KC Machine to Butler Machine, repositioning precision machining toward "complex, higher-value" aerospace and defense work. “Butler Machine gives us precision manufacturing capabilities that complement the engineering certification, aircraft modification, mission systems integration and defense electronics capabilities we already have across Butler National.” — Jeffrey Yowell, Executive or Senior Management · 2026-09-11
The quiet negative: sports wagering got worse
The headline framing of the gaming segment was upbeat — extensions with the Kansas Lottery (three years) and DraftKings (ten years). Read the fine print, though, and the sports wagering economics deteriorated on two fronts at once. Mobile sports wagering revenue fell to $1.1M from $1.3M on a lower hold percentage, and the DraftKings deal was renegotiated at a worse split.
As part of the extension, we agreed to a lower revenue participation percentage than under the original agreement. While we would obviously have preferred to maintain the prior economics, we believe the new terms reflect the evolution of the Kansas sports wagering market.
Ten years of visibility is worth something, but investors should hear the trade plainly: the company traded margin for duration on its one fast-decaying digital revenue line. This is the mirror image of the aerospace story — a mature, structurally declining piece being quietly de-emphasized.
Valuation has already caught up
The tape tells its own story. Over its multi-decade history the stock has returned +878%, but the last 90 trading days show a fresh, unbroken +37%, lifting Price to Revenue to 2.7x — up 127% year over year and up roughly 356% over the past eight years. On the earnings the company just reported, Price to Net Income sits near 12x. This is a re-rating of a formerly ignored microcap, and it lands in sharp contrast to management's own long-standing lament. On an earlier call, then-CEO Clark Stewart put it bluntly: “We believe we ought to trade at least 10x, but that's a wish, not a fact.” — Clark D. Stewart, Executive (likely CEO or President) · 2022-03-17 The wish has largely arrived.
Confluence, caveats, and the sector backdrop
Butler National is not alone in sensing a defense-electronics inflection. AeroVironment reported days earlier with its own inflection point language and a capacity expansion plan — the same theme of demand outpacing physical capacity that Butler describes, where the pacing item varies by program. That confluence is supportive, and it validates the premium multiple.
Two caveats are worth flagging. First, working capital is stretching: Receivables to Revenue has risen to about 51%, up 23 points year over year, even as Effective Net Cash sits near $6M after debt. Second, as prior management itself warned, mix makes aerospace margins lumpy — “Some quarters may reflect higher margins when we have a greater proportion of repeat projects or kit deliveries.” — Christopher Reedy, Executive, likely COO or another senior management role · 2025-12-12 Investors should not annualize the 25% segment margin, and management explicitly says no single quarter is a permanent level.
The governance wildcard is the ongoing CEO search; Executive Chairman Jeff Yowell framed continuity as the point. “Our objective is to identify the right leader for the next stage of Butler National's development.” — Jeffrey Yowell, Executive or Senior Management · 2026-09-11 For now, the operating story runs without a permanent chief executive, and the buyback has shrunk — repurchases were only ~$8,000 in the latest filing versus the roughly 1.5 million shares retired in the December 2025 quarter. The aerospace flywheel is real and company-unique; the casino is a cash cow being milked harder; and the multiple already reflects a lot of the good news.
