Who Innovative Solutions and Support (ISSC) is actually tied to

Start here: ISSC (ISSC) is embedded in the prime‑contractor ecosystem and its own filings hand you the guest list.

ISSC puts the top three customers on the record. > "tember 30, 2023, the three largest customers, Pilatus, ATSG and Textron accounted for 23%, 12% and 10% of total revenue, respectively." (ISSC / 10-K / 2025-12-23) That line pins down who brings in the money: Pilatus, ATSG (Air Transport Services Group, ATSG), and Textron (TXT) together make up nearly half of the named concentration in that disclosure.

Textron (TXT) appears not only as a buyer but in program language that reads like vendor and partner overlap. > "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…" (ISSC / 10-K / 2025-12-23) ISSC’s own wording ties Textron to specific airplane programs and OEM contracts, the same phrasing it uses when discussing suppliers and partners.

Boeing (BA) shows up the same way: platform names, OEM contracts and program backlog are how ISSC describes its ties to the industry’s largest primes. > "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." (ISSC / 10-K / 2025-12-23) ISSC frames its DoD work as routed through the big primes, Boeing (BA), Lockheed Martin (LMT), L3Harris (LHX), and lists those primes as the natural counterparty routes in its filings.

The company also lists a broad customer set in the same disclosure where it names federal agencies and large commercial carriers. > "OUR CUSTOMERS AND PRODUCT DISTRIBUTION The Company’s customers include the U.S. federal government (including the DoD, the Department of Interior and the Department of Homeland Security), Air Transport Services Group Inc. (“ATSG”), Amazon.com, Inc., American…" (ISSC / 10-K / 2025-12-23) That sentence puts ATSG (ATSG), Amazon (AMZN), American Airlines (AAL), FedEx (FDX) and others on the customer map alongside government work.

Honeywell (HON) appears in two roles: as an asset counterparty in a recent acquisition and as a named competitor. > "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…" (ISSC / 10-K / 2025-12-23) > "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…" (ISSC / 10-Q / 2026-05-15) ISSC discloses the Honeywell deal language and the related accounting assignments in filing text rather than as a side note.

The company also names its competitive set by product. > "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." (ISSC / 10-K / 2025-12-23) ISSC explicitly places Honeywell (HON), Elbit (ESLT) and Garmin (GRMN) in the same market buckets it sells into.

On financing, ISSC records a fresh credit line led by JPMorgan. > "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." (ISSC / 8-K / 2025-08-14) The filing names JPMorgan (JPM) as the lead arranger on a $100 million committed facility that the company discloses in its public filings.

Read straight through the quotes and the picture is literal: ISSC’s filings point to a concentrated customer mix, recurrent program ties to the big primes (Textron, Boeing, Lockheed), a recent asset deal with Honeywell, and a named lender on a five‑year credit agreement. Each of those threads is a disclosed relationship in the filings, not an analyst’s inference.

These are relationships disclosed in ISSC’s SEC filings, mapped by Jodie’s analytics. This is not investment advice.
