1. F1. Pursuant to the Huntington Ingalls Industries, Inc. 2012 and 2022 Long-Term Incentive Stock Plan (together, the "LTISPs"), dividend equivalents are credited on each director stock unit ("SUA") held by the Reporting Person following the payment of the Company's quarterly cash dividend. Each SUA represents a right to receive one share of Company common stock, which will generally become payable within 30 days following the date a non-employee director ceases to provide services as a member of the board of directors. The number of dividend equivalents acquired by the Reporting Person under the LTISPs is calculated by dividing the aggregate amount of the dividend paid on the total number of SUAs held by the Reporting Person by the closing price of a share of Company common stock on the dividend payment date.
