[Form 4] Ducommun Incorporated Insider Trading Activity

Rhea-AI Filing Summary

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.

Insights

Financial Analyst

TL;DR: Minor tax-driven insider withholding; no signal change; impact negligible.

The Form 4 shows an automatic code-F transaction—893 shares withheld at $80.57 to cover taxes on 1,661 RSUs that vested the same day. Post-transaction ownership remains sizeable at 68,777 shares, demonstrating continued exposure to Ducommun’s equity upside. Because the insider neither sold shares for cash nor executed an options trade, the event lacks informational content about future fundamentals. From a valuation perspective, the float increases marginally, but the share count change is de-minimis versus the company’s outstanding shares, leaving earnings-per-share metrics effectively unchanged.

Corporate Governance Expert

TL;DR: Routine Section 16 compliance; governance posture unchanged.

Code-F withholdings are standard practice to meet IRS obligations at vesting and do not reflect discretionary trading. The officer remains compliant with Section 16 reporting deadlines, filing within two business days (transaction on 06/20/25; filing on 06/23/25). No Rule 10b5-1 plan was invoked, but that omission is not concerning because the transaction is exempt. Governance risk is therefore unchanged, and there are no red flags regarding insider intent or timely disclosure.
