Insights

Corporate Insider / Compensation Analyst

TL;DR: CEO received RSUs and sold shares to cover taxes, modest net dilution of cash holdings.

The reporting shows a grant of 66,372 RSUs awarded on 04/02/2025, structured to vest quarterly through 04/02/2028. RSUs are contingent rights that convert to common shares or cash at the issuer's discretion, increasing potential future share issuance.

To satisfy tax withholding on vesting, 28,343 shares were sold at a weighted-average price of $4.62. This is a routine tax-settlement sale rather than an indicated change in economic view; monitor aggregate insider sales for trend changes over the next 12–18 months as additional quarterly vesting occurs.

Equity Ownership / Governance Specialist

TL;DR: Insider still retains substantial direct and derivative ownership after transactions.

Following the transactions the filing reports 568,164 common shares owned directly and 663,716 shares when including RSU-derived shares, reflecting continued significant insider alignment with shareholders. The form identifies the reporting person as both a director and the CEO of the cybersecurity business unit.

Key dependencies include the company's choice to settle RSUs in cash or shares and the pace of future vesting; watch the quarterly vesting schedule through 04/02/2028 for further dilution or tax-sale activity that could affect free float in the near term.
