Shake Shack Inc. reported an insider ownership change involving Stephanie Ann Sentell and the company’s Class A common stock. The transaction occurred on July 15, 2026, and was reported on a Form 4 filed July 17, 2026. The filing describes the action as a tax-withholding transaction tied to the vesting of restricted stock units previously granted to Sentell under her employment agreement with Shake Shack and the company’s 2015 Incentive Award Plan, as amended. Rather than an open-market sale, the reported change reflects shares of Class A common stock withheld by the company to satisfy tax obligations arising when the RSUs vested. The RSU award referenced in the filing vests in four equal annual installments, subject to Sentell’s continued service with Shake Shack. The vesting dates are July 15, 2025, July 15, 2026, July 15, 2027, and July 15, 2028. The July 15, 2026 event therefore corresponds to the second scheduled vesting tranche under that award. The provided filing text does not include the number of shares withheld, the deemed transaction price, the Form 4 transaction code, or Sentell’s beneficial ownership after the transaction. The explanatory note, however, makes clear that the reported ownership change was administrative and tax-related, connected to equity compensation vesting rather than a discretionary sale of Shake Shack shares by Sentell. The form was signed on Sentell’s behalf by Ronald Palmese Jr., Esq., acting as attorney-in-fact.
