[Form 4] Commault Systems, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Commvault director Vivie Lee received 1,189 restricted stock units that vest 100% on the later of the one-year anniversary of grant or the 2026 Annual Meeting, increasing her reported beneficial ownership to 14,739 shares. The award was reported as a grant with a $0 cash price, reflecting typical equity compensation in the form of restricted stock units.

Subsequently, Lee sold 765 shares at $182.92 per share pursuant to a pre-existing Rule 10b5-1 trading plan adopted February 3, 2025, reducing her beneficial ownership to 13,974 shares. The transactions are routine director compensation and plan-based selling; no derivative transactions or exercisable options are reported.

Positive

• Received 1,189 restricted stock units with a clear vesting schedule, aligning director compensation with shareholder interests
• Sale executed under a Rule 10b5-1 trading plan, indicating pre-established, systematic selling rather than ad hoc insider trades

Negative

• Selling 765 shares at $182.92 reduced beneficial ownership from 14,739 to 13,974 shares, which could be viewed unfavorably by some investors
• No derivative securities reported, limiting insight into potential future dilution from option exercises or other commitments

Insights

Financial Analyst

TL;DR: Director grant offsets modest plan-based sale; ownership remains meaningful and changes appear non-dilutive.

The grant of 1,189 restricted stock units increases reported beneficial holdings to 14,739 shares, while the later sale of 765 shares at $182.92 under a Rule 10b5-1 plan reduces holdings to 13,974 shares. From a capital-structure perspective the RSU grant is an equity compensation event with $0 cash price and a delayed vesting condition tied to time or the 2026 Annual Meeting, so immediate dilution is limited to standard reporting effects. The sale was executed under an established trading plan, which supports orderly disposition rather than opportunistic trading.

Corporate Governance Expert

TL;DR: Transactions follow standard governance practices; 10b5-1 use increases transparency but merits routine monitoring.

The reporting shows a director receiving time‑based RSUs and later selling a portion of shares under a 10b5-1 plan adopted February 3, 2025. The explicit vesting condition (one-year anniversary or 2026 Annual Meeting) is clear and the reliance on a pre-existing trading plan for the sale reduces concerns about insider timing. Both the grant and the sale were disclosed on Form 4, providing transparency consistent with Section 16 reporting obligations.
