Semtech Corp. reported an insider ownership change involving Paul V. Walsh Jr. in the company’s common stock, with the transaction dated July 22, 2026. The Form 4 was filed on July 24, 2026. The filing states that the reported transaction was made pursuant to a Rule 10b5-1 trading plan adopted by Walsh on July 9, 2025. Rule 10b5-1 plans are prearranged trading programs that allow corporate insiders to buy or sell company securities according to preset instructions, typically to reduce concerns that trades were made on the basis of material nonpublic information. The document identifies the security involved as Semtech common stock, but the provided filing text does not include the transaction table that would normally specify the transaction code, number of shares, price, whether the transaction was a purchase, sale, option exercise, grant, or other disposition, and Walsh’s ownership following the transaction. As a result, the filing clearly reports a change in beneficial ownership but does not provide enough detail in the supplied text to quantify the size or economic value of the trade. The filing was signed on Walsh’s behalf by Mark Lin under a power of attorney dated October 6, 2023. The key substantive point is that a Semtech insider’s common-stock transaction occurred on July 22, 2026, and that it was executed under a previously adopted 10b5-1 plan rather than presented as a discretionary open-market trade made at the time.
