About Aerojet Rocketdyne Holdings, INC.

Aerojet Rocketdyne Holdings, Inc. (ticker AJRD) was a US aerospace and defense company listed on the NYSE in the United States, best known for propulsion systems and missile-related technologies. The group was built around the Aerojet and Rocketdyne brands, two long-standing names in the American space and defense industrial base. The company traces its corporate roots to 1915, when it was incorporated in Ohio, and later reincorporated in Delaware in 2014. That long operating history underscores its deep exposure to US government programs and mission-critical engineering work. At its core, AJRD designed, developed, and manufactured propulsion products and systems for the US Department of Defense, NASA, and major aerospace and defense prime contractors. Its portfolio included rocket motors, liquid and solid propulsion systems, missile propulsion components, and related subsystems for space launch, strategic defense, tactical missile programs, and human spaceflight missions. These are highly specialized markets with substantial barriers to entry, where qualification cycles are long and reliability standards are exceptionally high. From a competitive standpoint, Aerojet Rocketdyne held a meaningful position in several critical niche categories within the US aerospace supply chain. It was not a broad diversified prime contractor; rather, it was a specialist supplier whose value proposition rested on propulsion expertise, program heritage, and technical know-how. That specialization made the business strategically important, but also tied performance closely to US government procurement, defense budgets, and the timing of contract awards. In other words, revenue visibility depended heavily on federal spending patterns and program milestones. Geographically, the company was primarily US-based, with manufacturing and engineering activities concentrated in the United States. Its historical headquarters were in Rancho Cordova, California. Commercially, the business was overwhelmingly domestic and government-oriented, with relatively limited direct international exposure compared with larger defense peers. A key recent development is that Aerojet Rocketdyne no longer exists as an independent listed company. L3Harris Technologies completed the acquisition in 2023, and Aerojet Rocketdyne’s operations were folded into L3Harris’s portfolio. As a result, AJRD is now mainly relevant as a historical reference for SEC filings, including insider transactions and legacy corporate disclosures, rather than as an actively traded standalone equity. For investors, the name still carries weight because of the company’s role in US propulsion technology and its long-standing presence in mission-critical defense and space programs.
