[1] Transformation costs represent non-recurring expenses for strategic projects with anticipated long-term benefits to the Company focused on cost reduction and productivity improvement that do not meet the definition of restructuring charges. These costs are directed at simplifying, standardizing, streamlining, and optimizing the Company’s operations, processes and systems to permanently alter the Company’s operations for the long term. For a project to be considered transformational, successful completion of the project must be expected to bring long-term material benefits to the organization and involve significant changes to process and/or underlying technology. Transformation costs in the period result from actions taken as part of the Company’s 2024 transformation plan and primarily relate to one time asset write downs associated with changes in technology, one time inventory write downs relating to restructuring actions taken in the period, and third-party consulting costs associated with process and systems re-design.

[2] Includes expenses related to governance-related matters.
