"tember 30, 2023, the three largest customers, Pilatus, ATSG and Textron accounted for 23%, 12% and 10% of total revenue, respectively." (Innovative Solutions and Support / 10-K / 2025-12-23)
ISSC’s own filing names Textron (TXT) among its top three customers — 10% of revenue — and that number shows up again across other program notes. The point: Textron isn’t just a buyer in the filing language, it also appears as an OEM partner and program counterparty.
"This order marks our latest OEM contract and builds on existing programs with Pilatus for the PC-24, Textron for the King Air 260/360 and Boeing for the KC-46A, KC-767 and the T-7A OUR BUSINESS MODEL We specialize in providing systems integrations…" (Innovative Solutions and Support / 10-K / 2025-12-23)
ISSC calls out Textron (TXT) and Boeing (BA) in the same breath as OEM program customers for specific aircraft lines. That sentence is used by ISSC to describe the OEM contracts that underlie its systems-integration business.
"The backlog includes committed purchases and excludes potential future sole-source production orders from products developed under the Company’s engineering development contracts (“EDC”) programs, including the Pilatus PC-24, the KC-46A and the Textron King…" (Innovative Solutions and Support / 10-K / 2026-02-13)
The company’s backlog language again ties ISSC to Textron (TXT) program work — this is filed as part of the company’s description of its EDC-developed products and potential sole-source production.
"Currently, we support multiple OEM platforms, including those with the Boeing Company, Eclipse Aerospace, Lockheed Martin, and Pilatus Aircraft. 5 Table of Contents Products We manufacture, market, and sell a wide range of high-value, advanced avionics…" (Innovative Solutions and Support / 10-K / 2025-12-23)
ISSC explicitly lists Boeing (BA) and Lockheed Martin (LMT) as OEM platforms it supports. Those primes show up as customers or OEM partners across the filing.
"DoD programs generally take one of two forms: a subcontract with a prime government contractor, such as Boeing, Lockheed Martin, or L3 Harris Technologies, or a direct contract with the appropriate government entity, such as the U.S." (Innovative Solutions and Support / 10-K / 2025-12-23)
The filing frames ISSC’s DoD work as routed through the big primes — Boeing (BA), Lockheed Martin (LMT), and L3Harris (LHX) are named examples of prime contractors under which ISSC may operate.
"Recent Acquisitions In June 2023, the Company entered into an Asset Purchase and License Agreement (the “June 2023 Honeywell Agreement”) with Honeywell International, Inc. (“Honeywell”) pursuant to which Honeywell sold, assigned or licensed certain assets…" (Innovative Solutions and Support / 10-K / 2025-12-23)
ISSC discloses a June 2023 agreement with Honeywell (HON) involving asset purchase and license terms. Honeywell appears both as a counterparty in that transaction and in other parts of the filing as a competitor.
"Goodwill resulting from the Honeywell Generators Agreement has been assigned to the Company’s one reporting unit and is fully deductible for U.S. income tax purposes. Transition services agreement Concurrent with the Honeywell Generators Agreement, the…" (Innovative Solutions and Support / 10-Q / 2026-05-15)
A later filing ties the Honeywell transaction to goodwill and transition services language — the Moog (MOG-A) referenced in the facts is tied to that transition wording in the 2026 filing.
"On July 18, 2025, the Company entered a new five-year , $ 100 million committed credit agreement (the \"Credit Agreement\") with a lending syndicate led and arranged by JPMorgan Chase Bank, N.A." (Innovative Solutions and Support / 8-K / 2025-08-14)
ISSC’s debt package is explicit: a $100 million committed credit facility led by JPMorgan (JPM), disclosed in mid‑2025.
"With respect to our products, the Company’s principal competitors include Honeywell Aerospace, Collins Aerospace, GE Aerospace, Thales Defense & Security, Inc., Elbit Systems and Garmin Ltd." (Innovative Solutions and Support / 10-K / 2025-12-23)
The company lists Honeywell (HON), Elbit (ESLT) and Garmin (GRMN) among principal competitors for its avionics and related products.
Read straight from the filing language: ISSC (ISSC) sits inside a mesh of prime contractors (Boeing (BA), Lockheed Martin (LMT), L3Harris (LHX), General Dynamics (GD), Northrop Grumman (NOC)), a repeat counterparty in Textron (TXT) that shows up as customer, program OEM and backlog name, a disclosed asset deal and transition tie to Honeywell (HON) and Moog (MOG-A), and a $100 million lender commitment led by JPMorgan (JPM).
These are relationships disclosed in SEC filings, mapped by jodie's analytics, and this is not investment advice.
