## About

Founded in 1849 by Charles Louis Ducommun in Los Angeles, the business began as a general store supplying prospectors during the California Gold Rush before evolving into a metals supply and manufacturing operation. Stephen G. Oswald has led the company since 2018, steering a publicly traded enterprise that serves as a Tier 1 and Tier 2 supplier for major commercial aerospace and defense programs. The founding family sold its remaining stake decades ago, and the firm now operates as a widely held NYSE-listed manufacturer without any single-family wealth origin. The company engineers and manufactures electronic systems, structural components, and subassemblies for military and commercial aircraft, rotorcraft, space systems, and industrial automation applications. Key programs include the Boeing 737 MAX, Airbus A320 family, F-35 Lightning II, and various missile and radar platforms. Ducommun's operations are split between two segments: Electronic Systems, producing cable assemblies, illuminated cockpit panels, and radar enclosures, and Structural Systems, delivering titanium and aluminum fuselage skins, wing components, and engine nacelle parts. The firm maintains long-term contracts with the US Department of Defense and primes such as Northrop Grumman and Raytheon Technologies. Ducommun operates roughly 15 manufacturing and engineering sites across the United States, with concentrations in California, Arkansas, Oklahoma, and New York. The company acquired Magnetic Seal, a provider of proprietary sealing solutions for aerospace engines and gearboxes, in August 2022 to deepen its aftermarket and engineered products portfolio. In May 2024, Ducommun was selected to supply electromechanical actuation systems for a classified defense platform, extending its content on next-generation military programs. The firm publicly trades on the NYSE under ticker DCO, with no separate asset management or family office vehicle. Ducommun's structural differentiation lies in its origin story and program longevity rather than a unique governance or sourcing edge. As the oldest company in California, it possesses deep institutional knowledge from decades of program lifecycles and a long-tenured manufacturing footprint in high-barrier-to-entry defense markets. Its succession of professional management, free of any founding-family influence, makes it a pure-play industrial manufacturer subject to standard public-market governance and the cyclical patterns of aerospace build rates.

## Questions

### Who runs investment decisions at Ducommun?

Ducommun is not an investment firm; it is a publicly traded aerospace and defense manufacturer (NYSE: DCO). Capital allocation decisions — including mergers, acquisitions, and shareholder returns — are made by Chairman and CEO Stephen G. Oswald, CFO Suman Mookerji, and the board of directors, subject to standard public-company governance. The company does not manage external capital or operate as a family office.

### How is Ducommun related to the Ducommun family?

The company was founded in 1849 by Charles Louis Ducommun, a Swiss-born watchmaker who opened a hardware store in Los Angeles. The founding family sold its controlling interest many decades ago and is no longer involved in operations or governance. The company now functions as a widely held, independent public corporation with a professional management team.

### What is Ducommun's known posture on co-investments alongside external GPs?

Ducommun does not engage in co-investments or operate any fund structure. As an operating company, its external capital transactions are limited to corporate M&A and strategic investments that enhance its manufacturing capabilities, such as the 2022 acquisition of Magnetic Seal. There is no LP/GP dynamic.

### Which sectors does Ducommun explicitly avoid?

Ducommun does not invest in or operate within software, consumer goods, financial services, or healthcare. The company's identity is tied exclusively to industrial manufacturing, specifically engineered components and subassemblies for aerospace, defense, and select industrial end markets. It does not have a venture arm or a portfolio outside of its core operational footprint.
