[Form 4] Cable One, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Seaport Entertainment Group Inc. (SEG) – Form 4 filing

CFO Matthew M. Partridge reported an automatic share withholding on 01 Aug 2025 related to the vesting of restricted stock issued under the 2024 Equity Incentive Plan. The issuer withheld 5,429 common shares (Transaction Code “F”) at a reference price of $22.48 to satisfy payroll-tax obligations; no open-market sale or cash proceeds occurred.

Following the tax withholding, Partridge’s direct ownership totals 82,079 SEG shares. No derivative positions were reported or altered. Because Code F denotes a compulsory, non-discretionary transaction, the event is generally viewed as administratively neutral and does not signal a change in executive sentiment or company fundamentals.

Positive

• CFO retains 82,079 shares, indicating continued equity alignment; the disposal was strictly tax-related and not discretionary selling.

Negative

• None.

Insights

Securities Analyst

TL;DR: Routine tax-withholding; no open-market selling; CFO still owns 82k shares—neutral for SEG valuation.

The filing records a Code F disposition, which is mechanically triggered when restricted stock vests. Such transactions neither add nor remove cash from the executive and typically have no predictive power for future price moves. Partridge’s post-transaction stake (≈82 k shares) remains sizable, maintaining alignment with shareholder interests. No derivatives or options were exercised, so dilution risk is unchanged. Overall, the disclosure is non-impactful for financial models or sentiment analysis.

Corporate Governance Expert

TL;DR: Administrative insider withholding complies with Rule 16a; governance outlook unchanged.

Code F events reflect good compliance practice, as tax liabilities are settled immediately via share withholding, avoiding potential trading-window issues. The continued holding the CFO retains supports long-term incentive alignment. No governance red flags, related-party concerns, or policy breaches are evident. I classify the impact as neutral; investors need not adjust risk assessments based on this filing.
