Employee Note from Leadership Team

Subject: A Message From Our Leadership

Team,

Today we want to share an important update: Marine Products has entered into a definitive agreement to merge with MasterCraft, a leading innovator, designer, and manufacturer of premium performance and leisure powerboats. This is an exciting new chapter for Chaparral and Robalo, and a strong endorsement of the hard work and dedication of each and every one of you.

This transaction brings together two iconic, market leading recreational marine companies. The combined company will benefit from a more diversified portfolio of leading brands, now including MasterCraft, Crest, and Balise, supported by advanced product development and manufacturing platforms as well as an expanded dealer network.

MasterCraft will maintain the Chaparral and Robalo leadership team, brands and employees as a separate operating unit. Our teams, dealer and supplier relationships, and operating model remain in place, and we will continue to operate business as usual. Our focus remains on executing our plans, supporting our dealers, suppliers, and customers, and delivering the results we expect of ourselves.

We are looking forward to sharing more details with you in the coming days and weeks as we work to finalize this transaction, which we expect to be completed in the second calendar quarter of 2026.

If you have any questions, or receive any external inquiries from media, dealers, suppliers, etc., please forward them to your manager or the executive team.

Thank you for your continued focus, professionalism, and commitment. More to come soon.

Ben, Buck, Ann, Mike, Bill, and Jeff

Chaparral and Robalo Leadership Team
