[425] MARINE PRODUCTS CORP Business Combination Communication

Rhea-AI Filing Summary

MasterCraft Boat Holdings has agreed to combine with Marine Products Corporation in a cash-and-stock transaction, creating a broader portfolio of marine brands including MasterCraft, Crest, Balise, Chaparral and Robalo. Marine Products adds a global dealer network of more than 300 partners focused on recreational and sport‑fishing powerboats.

The closing is expected in the second calendar quarter of 2026, subject to approval by both companies’ shareholders and customary closing conditions. Until then, MasterCraft and Marine Products will operate as separate companies, with no immediate changes to employees’ teams, roles or responsibilities.

The message emphasizes continued focus on serving customers and dealers while a dedicated integration planning team is formed. It also highlights that formal transaction details will be provided in a planned Form S-4 registration statement and joint proxy statement/prospectus to be filed with the SEC, along with standard forward‑looking statement cautions.

Insights

M&A and equity strategist

MasterCraft and Marine Products plan a strategic cash-and-stock combination to build a larger, more diversified boat manufacturer.

The planned combination of MasterCraft and Marine Products would unite premium towboats, pontoons and sport‑fishing boats under one corporate umbrella. Management frames the deal as creating a more diversified portfolio, with Marine Products contributing Chaparral and Robalo brands plus a dealer base exceeding 300 partners.

The companies expect closing in the second calendar quarter of 2026, contingent on shareholder approvals and customary conditions. Until then they will operate independently, which limits near‑term operational disruption but delays realization of any synergies. Actual benefits will depend on how effectively the planned integration team aligns product, dealer and manufacturing strategies once approvals are obtained.

Investors are directed to a forthcoming Form S-4 registration statement and joint proxy statement/prospectus for detailed terms, risk factors and pro forma information. These documents, once filed, will clarify the cash versus stock mix, governance of the combined entity, and the financial profile management anticipates after closing.

Subject: MasterCraft and Marine Products to Combine

To: All MasterCraft Employees

Date: February 5, 2026

MasterCraft Team,

A short while ago, we issued two important announcements, and I wanted to reach out directly to share my perspective. First, we reported here another quarter of strong results that exceeded our expectations and demonstrate the continued momentum underway at MasterCraft thanks to your efforts and consistent execution. The foundation of our business is as robust as ever, and we’re continuing to deliver on our key initiatives in what remains a dynamic demand environment.

That brings me to the second announcement, which is all about the future of our great company. As you may have seen, we announced here that MasterCraft has entered into an agreement to combine with Marine Products in a cash and stock transaction, creating a more diversified portfolio of proven brands – MasterCraft, Crest, Balise, Chaparral, and Robalo – across four highly attractive and distinct categories.

This is a significant milestone for our company, and we are confident that the combination of MasterCraft and Marine Products will put us in an even stronger position to shape the future of the marine industry.

For those who may be less familiar with Marine Products, they are a leading manufacturer of recreational and sport-fishing powerboats, anchored by the respected Chaparral and Robalo brands. Marine Products also brings a robust global dealer network of more than 300 partners. By uniting our innovation prowess and operational excellence with Marine Products’ best-in-class products and strong dealer relationships, the combined company will gain the scale, reach, and product breadth needed to serve and meet the evolving needs of boating enthusiasts across multiple categories.

Marine Products shares our commitment to delivering an exceptional boating experience for our customers. Quality, innovation, and craftsmanship drive everything they do. By bringing our companies together, we’ll unlock meaningful benefits for our teams, our dealers, and our customers, including:

• A proven, diversified, and complementary portfolio of leading brands. Combining MasterCraft’s category leadership in premium performance and leisure, together with Marine Products’ leading recreational brand (Chaparral) and strong sport fishing presence (Robalo) creates a more diversified offering to meet the needs of an expanded customer base.

• Compatible dealer networks. MasterCraft’s and Marine Products’ complementary coastal and inland dealer networks and commercial capabilities expand our presence in key geographies and enhance growth opportunities to drive long-term value.

• Enhanced manufacturing capabilities. Bringing together powerful product development and manufacturing and with facilities in Tennessee, Michigan, and Georgia, we expect to accelerate new product launches, improve production efficiency, and improve buying power.

Importantly, today’s announcement is just the first step in a longer process. We expect the transaction to close in the second calendar quarter of 2026, pending approval from both MasterCraft and Marine Products shareholders and the completion of customary closing requirements. Until that time, MasterCraft and Marine Products will continue to operate as separate, independent companies.

While this is exciting news, please note that for now, it remains business as usual. There are no changes to your teams, roles, or responsibilities. Our focus remains the same: serving our customers, supporting our dealers, and delivering the quality and performance that define our company.

Over the coming weeks and months, we will stand up a dedicated team to work through the planning process to bring our two companies together. We will keep you informed of progress on this front as key decisions are made, however we do not anticipate that this combination will have a significant impact on the majority of our teams or their day-to-day work. With that said, there are a few details we can share now:

• I will continue to serve as CEO of the combined company, and Scott will serve as CFO.

• The combined company will be headquartered in Vonore, Tennessee, and will maintain Marine Products’ operating facilities in Nashville, Georgia.

• We also expect to maintain the Chaparral and Robalo leadership teams, brands and employees as a separate operating unit.

I will continue to keep you updated as we move forward. You’ll find attached FAQs that address many of the questions we anticipate will be top of mind. If something isn’t covered, please feel free to reach out to your manager.

I am incredibly proud of what this team has built – and of the strength, resilience, and innovation that continue to define MasterCraft. I’m confident that this marks the beginning of an exciting new chapter, one that expands our opportunities, accelerates our progress, and strengthens our ability to deliver the products and experiences our customers expect.

Thank you for your continued hard work and the commitment you show to MasterCraft every day. I’m excited for the opportunity to bring Marine Products’ Chaparral and Robalo brands into the MasterCraft portfolio and for all that we will achieve together.

Sincerely,

Brad Nelson
