Ducommun Incorporated (DCO) – Form 4 insider transaction
Senior Vice President of Electronic & Structural Systems, Jerry L. Redondo, filed a Form 4 covering activity on 20 June 2025. The sole transaction was coded “F,” indicating an automatic share withholding to satisfy tax liabilities arising from the vesting of 1,661 restricted stock units. Specifically, 893 common shares were withheld at an average price of $80.57, representing an implied value of roughly $71.9 k.
After the withholding, Redondo’s direct beneficial ownership stands at 68,777 shares. No derivative securities were exercised or disposed of, and the filing does not reference a Rule 10b5-1 plan. Because the transaction is administrative rather than discretionary, it is generally interpreted as neutral for market sentiment.
The 893-share reduction equals about 1.3 % of Redondo’s holdings and is immaterial relative to Ducommun’s roughly 11 million-share float. Investors typically view tax-related withholdings as having minimal impact on supply-demand dynamics or on management’s long-term commitment to the company.
