Bio-Rad Laboratories, Inc. reported an insider ownership change involving Eva Anette Engelhardt, with the reported event date listed as May 11, 2026. The filing relates to Bio-Rad’s Class A common stock, identified in the document as “Bio-Rad A Common Stock.” Engelhardt signed the Form 4 on May 12, 2026, and the filing was submitted on May 13, 2026. The document indicates that Engelhardt’s beneficial ownership changed, but the provided filing text does not include the transaction table that normally specifies the details of a Form 4 event. As a result, the filing excerpt does not disclose the number of shares involved, the transaction price, whether the action was an open-market purchase or sale, an option exercise, a grant, a vesting event, or another transaction type. It also does not provide a transaction code, post-transaction ownership amount, or any derivative-security details such as options, restricted stock units, vesting schedules, or expiration dates. Because Form 4 filings are used to report changes in beneficial ownership by directors, officers, and certain other insiders, the filing matters as a notice that an insider-related change occurred in Bio-Rad Class A common stock on May 11, 2026. However, without the missing transaction table, investors cannot determine from the provided text whether Engelhardt increased or decreased her holdings, whether the transaction was discretionary or part of a compensation plan, or the economic size of the event.
