Common Stock, par value $0.01 per share |
(b) | Name of Issuer:
Sleep Number Corp |
(c) | Address of Issuer's Principal Executive Offices:
1001 THIRD AVENUE SOUTH, MINNEAPOLIS,

, 55404. |
Item 4. | Purpose of Transaction |
Item 4 is hereby amended to add the following:
During 2023 and 2024, the Reporting Persons expressed their deep concerns about the Issuer's corporate governance and operational leadership, privately at first, and publicly after being left with no other choice. The Issuer has since made significant changes to its Board and leadership team. With a smaller and more effective Board, and with the hiring of the Issuer's new CEO, Linda Findley, the Reporting Persons believe the Issuer is now positioned for operational success and appropriately focused on unlocking the massive potential for shareholder value creation. The Reporting Persons have met extensively with Ms. Findley and her new team over the last several months and are deeply impressed by Ms. Findley, her strategy and the turnaround actions the Issuer has taken under her leadership. Ms. Findley and the newly configured team are executing with sharp focus and an urgency appropriate for the situation. The turnaround of the Issuer is well underway. The Reporting Persons have always admired the Issuer's differentiated products, powerful distribution channel strategy and loyal customer base. The Reporting Persons now believe the Issuer is set to exploit these real advantages. The Reporting Persons fully support Ms. Findley and her team and look forward to working constructively with her and the improved Board. | |
