Cadence Design Systems Inc. executive Paul Cunningham reported a series of insider transactions in the company’s common stock on July 15, 2026, according to a Form 4 filed July 17, 2026. The filing indicates Cunningham exercised stock options covering 1,000 shares of Cadence common stock at an exercise price of $138.02 per share. The options referenced in the report vested monthly at a rate of 1/48th per month beginning March 25, 2021, meaning the award was designed to vest over four years. The option exercise was reported as a derivative-securities transaction, typically associated with transaction code “M” when options are exercised into common stock. On the same date, Cunningham sold 2,000 shares of Cadence common stock at $383.36 per share. The filing states that the reported transaction was made under a Rule 10b5-1 trading plan adopted by Cunningham on March 16, 2026. Such plans allow insiders to schedule trades in advance under pre-set conditions, providing an affirmative defense against claims that trades were made based on material nonpublic information. After the reported transactions, Cunningham beneficially owned 127,586 shares of Cadence common stock. The sale price of $383.36 implies gross proceeds of about $766,720 from the 2,000-share sale, before commissions, taxes or other costs. The option exercise involved an aggregate exercise cost of $138,020 for the 1,000 shares acquired. The filing was signed on Cunningham’s behalf by Ahalya Hildreth, attorney-in-fact, on July 17, 2026.
