• Shares acquired: 18.638 share-equivalents; reported price per share: $0.00; reported total value: $0.
• Shares owned after the transaction: not specified in the Form 4 provided.
• Footnote: These shares reflect dividend equivalents credited on director stock units (SUAs) under HII’s 2012 and 2022 Long-Term Incentive Stock Plans. Dividend equivalents are converted into SUAs by dividing the dividend amount by the company’s closing share price on the dividend payment date.

Context

• This was not a market purchase or sale but a routine crediting of dividend equivalents to director stock units. Each SUA is a right to one share that generally becomes payable within ~30 days after a non-employee director stops serving on the board. Such credits are common and do not in themselves signal a buy/sell view by the insider.
