[Form 4] Huntington Ingalls Industries, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Huntington Ingalls Industries (HII) – Form 4 insider transaction

Executive Vice President & President of HII Mission Technologies, Edgar A. Green III, reported an open-market sale of 4,206.547 common shares on 08/04/2025 at a weighted-average price of $265.64 (price range $266.12-$266.55). Gross proceeds are roughly $1.12 million.

After the sale, Green directly owns 7,049.64 shares and indirectly holds 2,065.6 shares through the company 401(k) plan. No derivative transactions were reported, and no Rule 10b5-1 trading plan box was checked.

The disposition represents an estimated ≈37% reduction in the insider’s direct equity stake (11,256 shares before the sale versus 7,050 shares after). Although management continues to own stock, investors often view sizable discretionary sales by key officers as a modest negative signal absent offsetting information such as option exercise-related taxes or a pre-arranged trading plan.

Positive

• None.

Negative

• Senior officer sold 4,206 shares (~$1.12 M), reducing direct stake by roughly 37%, which can be viewed as a modest negative sentiment signal.

Insights

Financial Analyst

TL;DR: EVP sold ≈$1.1 M in HII stock, trimming direct stake by ~37%; signal mildly negative but not alarming given remaining ownership.

Context: Mr. Green is a senior operating executive running the Mission Technologies segment. This unit is central to HII’s strategic pivot toward higher-margin, technology-driven services.
Magnitude: 4,207 shares is modest against HII’s 39 M share float but material for an individual insider.
Signal: Lack of 10b5-1 designation suggests the sale was discretionary, which can be interpreted as reduced short-term conviction. However, Green retains over 9,000 total shares, aligning interests with shareholders.
Impact assessment: Transaction does not alter fundamentals or guidance; therefore, market impact should be limited, though quant funds may flag it in insider-sentiment screens.
