Insights

Equity compensation and governance analyst

CEO’s Form 4 shows routine tax withholding plus a clawback-related share return.

The filing indicates CEO Stephen G. Oswald had 2,185 shares withheld at $151.59 per share to cover tax obligations on 4,406 vested restricted stock units. This is a standard non-market transaction and does not represent an open-market sale.

A separate 2,221-share disposition reflects enforcement of Ducommun’s Second Amended and Restated Clawback Policy after restated financial statements. The company determined certain compensation would not have been earned, so vested RSUs were not delivered and shares were returned to the issuer.

Following these adjustments, Oswald directly holds 409,843 common shares. The transactions are administrative and policy-driven, so their informational value lies in confirming active clawback governance rather than signaling a change in the CEO’s market view of the stock.

restricted stock units financial

"settlement, on May 14, 2026, of 4,406 restricted stock units."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

Second Amended and Restated Clawback Policy financial

"In connection with the operation of the Issuer's Second Amended and Restated Clawback Policy"

Clawback Policy financial

"in accordance with the Issuer's Clawback Policy."

A clawback policy is a company rule that lets the firm take back pay, bonuses or stock awards from current or former executives if results are later found to be incorrect, misconduct occurred, or targets were missed. It matters to investors because it helps protect the value of their holdings by discouraging risky or fraudulent behavior and ensuring executive rewards reflect real, verified performance—think of it as a return policy for executive pay.

restatement financial

"with respect to the restatement and revision of the Issuer's previously issued financial statements"

A restatement is a company’s formal correction of previously released financial reports when errors or omissions are discovered, similar to fixing a report card after finding mistakes in the scores. It matters to investors because it can change past performance figures, alter valuation or earnings trends, and signal weaknesses in accounting controls or management oversight, which may affect confidence and the stock’s perceived risk.
