This is the public record of open-market stock transactions William Joseph Brennan has reported to the SEC on Form 4 as Pres & Chief Executive Officer of Credo Technology Group Holding Ltd (CRDO). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates. It is a record of what has been filed, not a portfolio or a recommendation, and insider selling in particular is routine and rarely a signal on its own.

Questions about this record

How many shares has William Joseph Brennan bought and sold?

William Joseph Brennan has disclosed 11 Form 4 transactions in the record we track, from Aug 1, 2025 to Jun 5, 2026: 11 sales worth $91,120,850 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 William Joseph Brennan 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 11 sales on this record, 9 were made under a Rule 10b5-1 plan and 1 were automatic tax withholding on vesting shares, leaving 1 that were the insider's own discretionary decision (worth $12,017,877). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.

What is William Joseph Brennan's role?

William Joseph Brennan files as Pres & Chief Executive Officer of Credo Technology Group Holding Ltd (CRDO). 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.

The largest single transaction on record is a sell of 196,444 shares of CRDO at $106.87, worth $20,994,800, filed Aug 5, 2025.

How current is this record?

The most recent Form 4 here was filed Jun 9, 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 William Joseph Brennan currently holds. Amounts are open-market and plan transactions reported on Form 4; grants and option exercises are not counted as buys.
