Workstream Updates

Next week, the Culture & Organization Design Integration Team and the Digital & Transformation Integration Team will come together on-site in the Winchester, VA office to advance key priorities for the merger. These in-person sessions are vital for aligning people, processes, and technology, ensuring we build a unified culture while modernizing systems to support our future growth. By collaborating face-to-face, the teams are driving the momentum needed to move integration forward and set the foundation for long-term success.

Important reminders:

Our priority is to continue to deliver the exceptional service our customers expect from American Woodmark. MasterBrand and American Woodmark remain separate organizations until the transaction closes, subject to certain conditions and approvals, and it is business as usual at American Woodmark.
