5 terms

performance stock unit award financial

"pursuant to the terms of a performance stock unit award granted on May 15, 2024"

total shareholder return financial

"the Company's total shareholder return satisfying specified benchmarks relative to the Russell 3000 index"

Total shareholder return is the overall gain an investor gets from owning a stock, combining changes in the share price plus any cash payouts like dividends, and assuming those payouts are reinvested in more shares. Investors use it like a single score that shows the true return on their investment—similar to checking both the growth of a savings account and the interest earned—to compare how well different companies or investments perform over time.

Russell 3000 index financial

"specified benchmarks relative to the Russell 3000 index pursuant to the terms"

A broad stock market index that tracks the performance of the roughly 3,000 largest publicly traded U.S. companies by total market value, representing almost the entire U.S. equity market. Investors use it like a big basket or thermometer: it provides a simple snapshot of overall U.S. stock market health, serves as a benchmark for funds and portfolios, and helps measure diversification, risk and returns over time.

tax withholding obligations financial

"shares automatically sold solely to satisfy tax withholding obligations of reporting person"

Rule 10b5-1 trading plan financial

"sale reported in this Form 4 was effected pursuant to an existing Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

How many CVLT shares does the reporting officer hold after these Form 4 transactions?

After the reported transactions, Danielle Abrahamsen holds 13,166 Commvault common shares directly. This reflects the net effect of a 328-share stock award and 378 shares sold, so only a modest portion of her total equity position changed hands.

Were Danielle Abrahamsen’s CVLT share sales part of a Rule 10b5-1 trading plan?

Yes. A footnote explains that the sale reported in this Form 4 was carried out under an existing Rule 10b5-1 trading plan adopted on February 17, 2026. Such plans pre-schedule trades, indicating these sales were planned rather than discretionary.

Why were some of Danielle Abrahamsen’s CVLT shares sold automatically?

A footnote states that certain shares were automatically sold solely to cover tax withholding obligations arising from vesting performance stock. Proceeds from these sales were submitted to the Internal Revenue Service, making them tax-driven dispositions rather than discretionary market sales.

How was the 328-share CVLT stock award to Danielle Abrahamsen determined?

The 328 shares were issued because Commvault’s total shareholder return met specified benchmarks relative to the Russell 3000 index. This grant came from a performance stock unit award granted on May 15, 2024, linking the payout to longer-term stock performance versus that index.
