Ducommun Discloses Principal Officer Departure in SEC Filing

Ducommun Incorporated, a Delaware-based aerospace and defense supplier with ticker symbol DCO, filed a Form 8-K with the Securities and Exchange Commission on May 4, 2026, announcing the departure of Vice President and Chief Financial Officer Rosellen M. Parker, effective May 10, 2026.

The filing affects Ducommun's executive team, which supports operations across its two segments: Structural Systems and Electronic Systems. These segments serve approximately 200 customers, including major contractors like Boeing and Lockheed Martin, generating annual revenues exceeding $700 million based on the company's most recent 10-K filing.

The CFO role oversees financial reporting for about 2,500 employees and influences budgeting for defense contracts valued at hundreds of millions annually.

Prior to the departure, Parker held the CFO position since 2022, managing compliance with SEC regulations and investor relations. The new state leaves the role vacant starting May 10, 2026, with no immediate successor named in the filing. The company stated in Item 5.02 that the departure is not due to any disagreement with the company on accounting principles or practices, financial statement disclosures, or internal controls.

The departure triggers a requirement under SEC rules for Ducommun to file a Form 8-K within four business days if a successor is appointed. It also activates provisions in the company's bylaws for the board to designate an interim CFO, potentially from existing executives, to maintain continuity in financial oversight.

Investors will receive updates through Item 7.01 Regulation FD disclosures, which include a press release attached as Exhibit 99.1 detailing the transition plan.

Ducommun last reported a similar executive change in 2024, when it elected a new director to its board following a retirement. The company operates under SEC oversight as a public entity since its 1970 listing, with routine filings including quarterly 10-Q reports next due by August 2026.
