[Form 4] Qualys, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Qualys (QLYS) Form 4: CEO & President Sumedh S. Thakar reported an administrative share withholding on 1-Aug-2025 (Transaction Code F).

• Shares withheld: 6,042 common shares
• Implied price: $130.53 per share (≈ $0.79 million)
• Reason: To satisfy tax obligations related to vesting RSUs (per footnote 1)
• Post-transaction holding: 209,920 shares held directly

This was not an open-market sale and does not alter Thakar’s economic exposure. Such tax-related withholdings are routine and typically carry neutral-to-slightly-negative sentiment only because the share count in public float rises modestly.

Positive

• None.

Negative

• 6,042 shares moved into the public float, representing a minor dilution and potential short-term supply increase.

Insights

Equity Analyst

TL;DR: Routine RSU tax withholding; negligible impact on QLYS valuation.

The Code F transaction indicates no discretionary selling pressure—shares were surrendered back to the company to cover withholding taxes on vested RSUs. The after-transaction stake of ~210k shares signals continued alignment between the CEO and shareholders. Dollar value (~$0.8 m) is immaterial relative to QLYS’s market cap, so I view the filing as neutral for the stock.

Corporate Governance Specialist

TL;DR: Insider still holds 0.55%+ of float; governance risk unchanged.

Automatic tax settlements generally do not reflect insider sentiment. Thakar retains a significant equity position, preserving incentives. No red flags emerge from this filing, and no pattern of aggressive selling is evident. Overall governance implications remain stable.
