The story

Ducommun was established in 1849 by Charles Louis Ducommun who was born in France and moved to Switzerland, where he and his 12 siblings were raised. A watchmaker by trade, Charles emigrated to the United States in the early 1840s, and opened a watchmaking business in New York City. To escape the populated city, he moved his business south and eventually embarked on a grueling journey from Fort Smith Arkansas, along the Santa Fe Trail, to California, lured by the discovery of gold in the area. Charles traveled on foot for the nine-month journey encountering harsh weather, starvation, illness and other threats. Charles arrived in Los Angeles in 1849 and opened a watch store. Over the next several decades, the business became a general store for miners and ranchers, then a hardware store catering to Los Angeles’s many growth industries including construction and oil exploration.

In 1896, Charles L. Ducommun died at the age of 76, leaving the business to his four sons, Charles Albert, Alfred, Emil, and Edmond. Under their leadership, the business was incorporated as Ducommun Hardware Company and primarily served as a metals distributer. Most notably, Ducommun backed early aircraft designer Donald Douglas with a line of credit, supplying metals and tools to the aviation industry, which was then in its infancy. During World War I, Ducommun was able to significantly expand its metals supply business, feeding copper, brass and steel to the emerging defense industry for shipbuilding and munitions.

In 1942, Ducommun again rebranded and became known as Ducommun Metals & Supply Co. When the United States entered World War II, Ducommun’s large inventory of stainless steel and carbon steel fed the production of bomber and fighter aircraft as well as military ships that were used in both the European and Pacific theaters. By 1949, Ducommun was recognized as the leading metal materials distributor in the West. Over the next 15 years, Ducommun diversified to support the needs of an aircraft industry that was rapidly incorporating more electronic components. The 1980s were years of restructuring and change for Ducommun and the industry overall. Both the metals and electronics distribution businesses were sold as the Company reoriented itself to become a member of the aerospace industry supply chain. Over the following decades, Ducommun’s growth was fueled by major contract wins with McDonnell-Douglas, Boeing, and key space platforms.

In 2017, Stephen G. Oswald was named President and CEO of Ducommun, and was appointed Chairman of the Board in 2018. Oswald immediately streamlined the organization, sharpening Ducommun’s strategic focus on A&D. The Company began its expansion into aftermarket products and services through five strategic acquisitions in Oswald’s first five years with the organization.

Risk factors and legal proceedings

The risks Ducommun names in Item 1A of its 10-K filed Feb 26, 2026: 37 risks under these headings, as written.16

  • CAPITAL STRUCTURE RISKS
  • We require a considerable amount of cash to run our business.
  • Our indebtedness could limit our financing options, adversely affect our financial condition, and prevent us from fulfilling our debt obligations.
  • The covenants in our credit facilities impose restrictions that may limit our operating and financial flexibility.
  • The typical trading volume of our common stock may affect an investor’s ability to sell significant stock holdings in the future without negatively impacting stock price.
  • Our amount of debt may require us to raise additional capital to fund acquisitions.
  • BUSINESS AND OPERATIONAL RISKS
  • Our end-use markets are cyclical.
  • We depend upon a select base of industries and customers, which subjects us to unique risks which may adversely affect us.
  • A significant portion of our business depends upon U.S. Government defense spending.
  • Exports of certain of our products and our production facility in Guaymas, Mexico are subject to various export control regulations and authorizations, and we may not be successful in obtaining the necessary U.S. Government approvals and related export licenses for proposed sales to certain foreign customers.
  • Risks associated with existing and new tariffs imposed by the U.S. administration or foreign governments potentially impacting the operation and conduct of our business outside the United States, including our production facility in Mexico, and the sale of products to customers outside the United States.
The other 27 risks
  • The inability to obtain raw materials and equipment from suppliers could harm our business.
  • Contracts with some of our customers, including Federal government contracts, contain provisions which give our customers a variety of rights that are unfavorable to us and the OEMs to whom we provide products and services, including the ability to terminate a contract at any time for convenience.
  • Further consolidation in the aerospace industry could adversely affect our business and financial results.
  • Our growth strategy includes evaluating selected acquisitions, which entails certain risks to our business and financial performance.
  • We may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense reductions, and may experience business disruptions associated with restructuring, footprint consolidations, realignment, cost reduction, and other strategic initiatives.
  • As we move up the value chain to become a more value added supplier, enhanced design, product development, manufacturing, supply chain project management and other skills will be required.
  • Risks associated with operating and conducting our business outside the United States could adversely impact us.
  • Customer pricing pressures could reduce the demand and/or price for our products and services.
  • Our products and processes are subject to risk of obsolescence as a result of changes in technology and evolving industry and regulatory standards.
  • We may not have the ability to renew facilities leases on terms favorable to us and relocation of operations presents risks due to business interruption.
  • LEGAL, REGULATORY, TAX, AND ACCOUNTING RISKS
  • We may be subject to litigation, other legal proceedings and indemnity claims, and, if any of these are resolved adversely against us in amounts that exceed the limits of our insurance coverage, it could have a material adverse effect on our business, financial condition, and results of operations.
  • Product liability claims in excess of insurance could adversely affect our financial results and financial condition.
  • We are subject to extensive regulation and audit by the Defense Contract Audit Agency.
  • Our operations are subject to numerous extensive, complex, costly and evolving laws, regulations and restrictions, including cybersecurity requirements, and failure to comply with these laws, regulations and restrictions could subject us to penalties and sanctions that could harm our business.
  • We are subject to a number of procurement laws and regulations. Our business and our reputation could be adversely affected if we fail to comply with these laws.
  • Unanticipated changes in our tax provision or exposure to additional income tax liabilities could affect our profitability.
  • Goodwill and/or other assets could be impaired in the future, which could result in substantial charges.
  • Environmental liabilities could adversely affect our financial results.
  • We use estimates when bidding on fixed-price contracts. Changes in our estimates could adversely affect our financial results.
  • Our ability to accurately report our financial results or prevent fraud may be adversely affected if our internal control over financial reporting is not effective.
  • LABOR AND SUPPLY CHAIN RISKS
  • We are dependent upon our ability to attract and retain key personnel.
  • Labor disruptions by our employees could adversely affect our business.
  • We rely on our suppliers to meet the quality and delivery expectations of our customers.
  • GENERAL RISKS
  • Cybersecurity attacks, internal system or service failures may adversely impact our business and operations.
  • We may be unable to adequately protect or enforce our intellectual property rights.
  • Assertions by third parties that we violated their intellectual property rights could have a material adverse effect on our business, financial condition, and results of operations.
  • Damage or destruction of our facilities caused by storms, earthquake, fires or other causes could adversely affect our financial results and financial condition.
