Innovative Aerosystems (Nasdaq: IA), the Exton, Pennsylvania avionics maker that traded as ISSC until August 2026, closed at $19.35 on October 16, 2026. Deep Sail Capital published a long thesis framing it as "A mini-TransDigm for Orphaned Avionics": buy or license cockpit product lines that bigger suppliers no longer want, keep supporting the installed base, and earn high margins on parts and service. The filings support the margin story so far; the open questions are price and execution on newly bought lines.

Key facts
- Ticker and exchange: Innovative Aerosystems, IA, Nasdaq (legal name Innovative Solutions and Support, Inc.; ticker changed from ISSC on August 18, 2026).
- The call: Deep Sail Capital's third-quarter 2026 letter includes a long thesis on IA, posted October 16, 2026 (UTC).
- Price: $19.35 on October 16, 2026; a $17.46 to $24.78 closing range since mid-July; $11.15 a year earlier.
- Latest quarter (fiscal Q3, ended June 30, 2026): sales of $26.7 million, up 10.7%; gross margin of 51.7% versus 35.6%; adjusted EBITDA of $7.7 million, up 74.7%.
- Trailing figures: adjusted EBITDA of $31.5 million over twelve months; backlog of $82.9 million.
- Deals: an April 2026 asset purchase and perpetual license for legacy Honeywell avionics lines, and a July 2026 purchase of Aydin Displays for $24.5 million in cash.
- Balance sheet: net debt of $43.8 million (1.4x leverage) at June 30, before Aydin was funded.
Is IA a good bet right now?
It depends on what you pay for the strategy. On our rough math, about 17.9 million shares outstanding at $19.35 is a market value near $346 million. Add June net debt of $43.8 million and the $24.5 million Aydin price, which the company said it funded from its credit facility, and enterprise value lands near $414 million, or about 13 times trailing adjusted EBITDA of $31.5 million before any Aydin contribution. That is a full multiple for a company this size. The bull case needs acquired lines to keep lifting margins and cash flow, as they did when gross margin jumped to 51.7% last quarter.
Why are investors bullish on Innovative Aerosystems?
- Orphaned lines at a discount. On April 2, 2026 the company announced an asset purchase and perpetual license from Honeywell covering legacy radios, autopilots, multifunction displays and transponders for smaller aircraft. The appeal is a long tail of installed units that still need parts and support.
- Margin evidence. The fiscal Q3 release showed net income of $4.5 million, adjusted EPS of $0.33 and nine-month free cash flow of $12.3 million, up 155%.
- More shelf space. The Aydin Displays deal adds rugged displays the company expected to bring about $16 million of calendar 2026 revenue.
- Optionality. IA reported a first production award for its Liberty Flight Deck from a Japanese eVTOL developer, set a long-term goal of $250 million in annual revenue, and joined the Russell 2000.

Other supporters:
- Undiscovered Compounders (@UCompounders) wrote on October 5 that IA is about 30% of his portfolio: "The stock trades at $19 and I'm convinced it'll hit $100 someday."
- Brian McCann (@Bootstrap68), who says he ran an independent RIA, replied to the thesis, "I love these 'build and buy' companies," and compared IA to Allient.
Who disagrees?
- Valuation. Insider Monkey (@insidermonkey) replied, "Good write-up on $IA but the stock doesn't look cheap at 25 times cash flow." Holler to Tide (@hollertotide) countered, "25x is distorted due to many one time expenses," pointing to the Exton buildout.
- Integration risk. Two acquisitions in four months means moving production, suppliers and customer support onto IA's own lines while staying on schedule for existing programs.
- Leverage. Aydin was bought with borrowed money, so leverage rises before the new revenue shows up in trailing EBITDA.
- Volatility. The stock has swung between $17.46 and $24.78 since mid-July on modest news.
What are the key facts to verify?
- Fiscal Q4 and full-year results for the year ended September 30, 2026. We did not find an announced date in the sources we checked.
- How much of the gross margin jump came from the Honeywell lines and how much from mix or one-time items.
- Net debt and leverage after the Aydin purchase.
- The size and timing of the Liberty Flight Deck eVTOL award.
- Deep Sail's full letter, which the fund says it posts with its investor letters.
What would prove it right or wrong?
Right: gross margin holds near 50% as Honeywell and Aydin revenue flows through, backlog grows from $82.9 million, free cash flow keeps pace with EBITDA, and further orphaned-line deals come at sensible prices.
Wrong: margins drift back toward the 35.6% of a year earlier, integration slips, leverage climbs without EBITDA following, or the eVTOL program stalls.
