What Happened

Kara R. Wilkinson, Executive Vice President and President of Newport News Shipbuilding (NNS) at Huntington Ingalls (HII), had 414.933 Restricted Stock Rights (RSRs) convert to common shares on 2026-02-26. The conversion was valued at $443.00 per share for a total of $183,815.

Transaction codes: M = exercise/conversion of a derivative (the RSRs converted to shares); F = shares withheld to pay tax withholding. This reflects a routine vesting/conversion and tax withholding, not an open-market sale or a separate cash purchase.

Context

These entries represent vesting/conversion of restricted stock rights and routine tax-withholding (a form of cashless settlement). Withholding to cover taxes is common and does not indicate an open-market sale by the insider.
For retail investors: this is compensation vesting, not an independent buy/sell signal. Purchases are generally more informative; this filing documents a company-paid compensation event with standard tax withholding.
