This is the public record of open-market stock transactions Sumedh S. Thakar has reported to the SEC on Form 4 as CEO & PRESIDENT of QUALYS, INC. (QLYS). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates.

Questions about this record

How many shares has Sumedh S. Thakar bought and sold?

Sumedh S. Thakar has disclosed 14 Form 4 transactions in the record we track, from Aug 14, 2025 to Aug 14, 2026: 14 sales worth $16,304,468 and no open-market purchases. Each figure is the reported share count multiplied by the reported price, so these are exact disclosed amounts, not estimates.

Is Sumedh S. Thakar selling a bearish signal?

Not on its own. Insiders sell for many reasons that have nothing to do with a view on the stock — diversification, taxes, estate planning, or a pre-scheduled plan set up months earlier. Of the 14 sales on this record, 14 were made under a Rule 10b5-1 plan and 0 were automatic tax withholding on vesting shares, leaving 0 that were the insider's own discretionary decision (worth $0). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.

What is Sumedh S. Thakar's role?

Sumedh S. Thakar files as CEO & PRESIDENT of QUALYS, INC. (QLYS). That role is taken from the Form 4 filings themselves. A Form 4 is filed with the SEC within two business days of an insider buying or selling their own company's stock.

What was Sumedh S. Thakar's largest single transaction?

The largest single transaction on record is a sell of 30,000 shares of QLYS at $135.00, worth $4,050,000, filed Jul 1, 2026.

How current is this record?

The most recent Form 4 here was filed Aug 17, 2026. Insiders have two business days to file after a trade, so this is close to real time, but it is a record of what has been disclosed, not a statement of what Sumedh S. Thakar currently holds. Amounts are open-market and plan transactions reported on Form 4; grants and option exercises are not counted as buys.

Source: Form 4 filings submitted to the SEC, the same public documents behind our insider trading tracker. Figures are open-market and plan transactions only; grants and option exercises are not counted as buys. A disclosure is not evidence of a market view, and none of this is investment advice.
