Huntington Ingalls (HII) Ex-CFO Thomas E. Stiehle Receives Award

What Happened

Thomas E. Stiehle, listed as Ex. VP and CFO of Huntington Ingalls Industries (HII), was granted/acquired 13.141 restricted stock rights (RSRs) on March 13, 2026. The reported acquisition price is $0.00 because these are dividend-equivalent RSRs (a derivative award), not a cash purchase.

Key Details

Transaction date: 2026-03-13 (Report filed: 2026-03-16). Filing was made within the typical Form 4 deadline (filed promptly after the transaction).
Transaction type/code: A (award/grant — derivative instrument representing RSRs); price reported $0.00.
Amount acquired: 13.141 RSRs (reported as shares); total cash paid: $0.
Shares owned after transaction: not specified in the information provided in your summary.
Footnotes: F1 — RSRs are contingent rights to receive equivalent common shares (or cash/combination at the Compensation Committee’s discretion) under the 2022 Long-Term Incentive Stock Plan (LTISP). F2 — these 13.141 RSRs represent dividend-equivalent rights credited after the company’s quarterly cash dividend; the number is calculated by dividing the aggregate dividend on the holder’s RSRs by the closing share price on the dividend payment date.

Context

This was not an open-market purchase or sale of common stock but a derivative award (dividend equivalents credited as additional RSRs). Such credits are routine under long-term incentive plans and do not necessarily indicate the insider buying or selling stock.

Footnotes (2)

[F1]Each Restricted Stock Right ("RSR") represents a contingent right to receive an equivalent number of shares of Company common stock, or, at the discretion of the Company's Compensation Committee, cash or a combination of cash and Company common stock. The RSRs were granted under the 2022 Long-Term Incentive Stock Plan ("LTISP").
[F2]The amount acquired represents dividend equivalent rights on the RSRs, which are credited following payment of the Company's quarterly cash dividend. Pursuant to the LTISP, the number of dividend equivalent rights acquired is calculated by dividing the aggregate amount of the dividend paid on the total number of RSRs held by the reporting person by the closing price of a share of Company common stock on the dividend payment date.
