A note from Buck Pegg & the Leadership Team to dealers regarding the transaction

Subject: Important Marine Products Business Update

To our valued dealers and partners,

I’m writing to you with some very exciting news – 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 transaction brings together two iconic, market leading recreational marine companies and together, and the combined company will benefit from a more diversified portfolio of leading brands with Chaparral, Robalo, MasterCraft, Crest, and Balise.

There are no changes to how we work with you. The Chaparral and Robalo leadership, our brands, and our employees will continue as a separate operating unit within MasterCraft. Your existing agreements, ordering processes, and day-to-day contacts remain in place. Our commitment to the success of our relationships with you will continue as always.

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

In the meantime, you can expect the same dedicated leadership, manufacturing and sales teams, services levels, and quality product you rely on today. If you have questions, your usual Chaparral and Robalo contacts remain available to support you.

Thank you for your continued trust and partnership. We are excited about the future.

Sincerely,

Buck Pegg and the Chaparral and Robalo Executive Team
