Costs Associated with Exit or Disposal Activities

On March 19, 2025, the Company announced its new corporate strategy, Grow Brand Love. In connection with this strategic transformation, the Company will be undergoing a reorganization (the “GBL Plan”) of its brand structure and certain functional areas within its North America reportable segment, as well as an optimization of its store fleet to primarily exit underperforming stores and reposition stores from declining venues. The Company expects to incur severance and other employee-related costs, and may also incur additional costs for contract termination and store closures as part of the GBL Plan. Management is unable to provide an estimate of such costs at this time based on the early stages of the GBL Plan. Management is targeting cost savings of up to $100 million from the actions under the GBL Plan on an annualized basis.

Departure of Certain Officers

As part of a reorganization announced on March 19, 2025, the Company reported that Jamie Singleton, Group President and Chief Consumer Officer, and Rebecca Wooters, Chief Digital Officer, are leaving the Company. Ms. Singleton will be exiting her current role effective March 31, 2025, and she may remain a full-time non-executive employee of the Company to provide support through a short transitional period after that date. Ms. Wooters will be departing from the Company on March 21, 2025.

Ms. Singleton and Ms. Wooters will be entitled to termination benefits and subject to ongoing covenants pursuant to their respective Termination Protection Agreements and restricted stock unit award agreements entered into with the Company which were in effect at the time of termination. In addition, Ms. Singleton would receive compensation and employee benefits during any period of transitional support.
