SEGMENT REORGANIZATION
Effective January 1, 2026, we reorganized the composition of our Flow and Water Solutions reportable segments to reflect how we are managing our business. As a result of this reorganization, our legacy residential and irrigation flow business moved from our Flow segment into our Water Solutions segment. The Pool segment remains unchanged. The applicable prior period amounts related to this change have been retrospectively reclassified to conform to the new composition. These changes have no impact on the Company’s historical consolidated financial performance or results of operations.
