About DUCOMMUN INC

Ducommun Incorporated (NYSE: DCO) is a specialized U.S. industrial company focused on the design, engineering, and manufacture of high-performance products used primarily in aerospace and defense, with additional exposure to selected industrial and medical applications. Listed on the NYSE market in the United States, Ducommun has a long operating history dating back to 1849, when it was founded by Charles L. Ducommun. The company describes itself as the oldest company in California, reflecting its deep historical roots in the Southern California industrial and aerospace ecosystem. Ducommun is headquartered in Costa Mesa, California, near Los Angeles. That location is strategically important: it places the company close to a major aerospace and defense supply chain while supporting an industrial footprint that remains overwhelmingly domestic. Management has stated that 95% of revenue is generated from U.S.-based operations, with the company’s only international facility located in Guaymas, Mexico. For international investors, this means Ducommun is primarily a U.S. manufacturing story with limited direct geographic diversification. The business is organized into two core operating segments: Electronic Systems and Structural Systems. Electronic Systems provides high-mix, low-volume electronic manufacturing solutions for high-cost-of-failure applications. Its capabilities include high-reliability interconnect systems, printed circuit board assemblies, integrated electromechanical assemblies, and related engineered solutions. Structural Systems focuses on large, complex contoured structural components and assemblies for aerospace and other demanding applications, using processes such as stretch-forming, thermal-forming, chemical milling, precision fabrication, machining, finishing, and subassembly integration. Ducommun’s end markets are concentrated in commercial aerospace, military and space, and selected industrial markets. Its competitive position is built on technical manufacturing expertise, long-cycle program content, and the ability to serve mission-critical platforms where reliability and qualification standards are high. In recent company communications, management highlighted growth tied to missile production, including the Patriot missile platform, as well as activity on key fixed-wing programs such as the F-35 and F-15. The company is also executing its VISION 2027 strategy, which emphasizes portfolio mix improvement, engineered products growth, and margin expansion. Recent corporate developments include an amended credit facility announced in late 2025, which expanded liquidity and strengthened the balance sheet, and an Investor Day scheduled for September 17, 2026, in New York City to update shareholders on strategic progress. Overall, Ducommun offers investors a niche aerospace-and-defense manufacturing profile with a long heritage, a U.S.-centric production base, and exposure to defense and commercial aerospace programs that can support medium-term visibility.
