Innovative Solutions and Support (ISSC) appears frequently alongside several large aerospace firms from multiple angles — especially Textron (TXT) and Boeing (BA). They appear as customers, OEM partners, contract primes, suppliers and competitors in ISSC’s filings. Below is the company’s own map of who it buys from, sells to, partners with, lends from, and competes against.

Start with the dual roles of OEM primes. ISSC explicitly links itself to Textron and Boeing as part of ongoing OEM programs:

"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 discloses that it participates in those OEM programs; the same sentence is used to show both supplier relationships and platform support.

ISSC also documents a recent asset and licensing deal with Honeywell (HON):

"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)

In its filing, ISSC says Honeywell transferred assets under a June 2023 agreement — the company reports that transaction as part of its supplier/asset disclosures.

A separate filing notes tax and transition-service items tied to the Honeywell generators deal and references Moog (MOG-A):

"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)

That’s ISSC’s own acknowledgement that the Honeywell transaction and associated agreements (and related parties like Moog in the disclosure) are embedded in its accounting.

Customers: big primes and carriers show up on the revenue page. ISSC calls out its top three customers and the share of sales they represented:

"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 lists multiple OEMs it supports — Boeing and Lockheed Martin (LMT) among them — in the same product-support disclosure:

"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)

Partners and prime-contractor context: ISSC frames many of its DoD relationships as either subcontracts with large primes or direct government contracts, naming those primes explicitly:

"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 backlog language also calls out the Textron and Boeing production lines again:

"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-Q / 2026-02-13)

Lender: ISSC discloses its primary committed credit facility and the bank lead:

"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)

Competitors: ISSC lists the usual avionics and aerospace suppliers as its principal competitors, including Honeywell and Elbit and Garmin:

"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)

And ISSC’s program/backlog disclosures tie Boeing back into the same product set it documents elsewhere:

"The backlog includes committed purchases and excludes potential future sole-source production orders under our current OEM contracts, including the Pilatus PC-24, the Boeing KC-46A and the Textron King Air 360 and King Air 260 ThrustSense® Autothrottle..." (Innovative Solutions and Support / 10-Q / 2026-05-15)

Bottom line, straight from the filings: ISSC’s disclosures repeatedly reference a short list of large aerospace primes — Textron (TXT), Boeing (BA), Lockheed Martin (LMT), Honeywell (HON/HONA), L3Harris (LHX), General Dynamics (GD), Northrop Grumman (NOC) — in supplier, customer, partner and competitor roles, and it runs a $100 million committed credit line led by JPMorgan (JPM). The company’s own language makes clear which external firms show up most often in its business descriptions.
