The stock was acquired on 16 May 2025 via restricted-stock vesting as compensation. No other insider sales have been reported in the past three months.

Insights

Securities Analyst

TL;DR: Small planned insider sale; negligible dilution; neutral signal.

The proposed divestiture represents 0.003% of shares outstanding and ≈0.1× average daily volume, implying minimal market impact. Because the stock was recently earned via restricted-stock vesting, the sale appears to be routine liquidity rather than a strategic exit. No pattern of selling is disclosed, and no material corporate developments are implicated. I view the filing as non-impactful for valuation or sentiment.

Corporate Governance Expert

TL;DR: Standard Rule 144 compliance; governance risk unchanged.

The insider complied with SEC Rule 144 timelines and aggregation rules, and affirmed the absence of undisclosed adverse information. The modest size and single-transaction nature do not raise red-flag governance concerns such as aggressive insider unloading. Overall, I assess the filing as routine and not materially impactful to shareholders.
