Insights

M&A Strategist

Transaction structure and timing noted; closing depends on customary approvals.

The communication confirms a planned combination and a filed Form S‑4, which signals a stock issuance and proxy solicitation process. The filing and planned mailing of a joint proxy statement/prospectus are standard steps to obtain shareholder approval.

Key dependencies include shareholder votes and customary closing conditions; timing is stated as the second calendar quarter of 2026. Subsequent regulatory disclosures and the definitive joint proxy will provide material economic terms and governance details.

Corporate Communications Advisor

Message emphasizes brand continuity and operational independence post‑close.

The letter frames Chaparral and Robalo remaining separate operating units and retaining dealer and supplier relationships, which suggests management intends to preserve brand equity and existing distribution channels.

This is a communications-first approach to reduce employee and dealer uncertainty; final operational integration details and any cost or revenue synergies are reserved for later disclosures in the Joint Proxy Statement/Prospectus.

Key Terms

3 terms

Form S‑4 regulatory

"filed with the SEC a registration statement on Form S-4"

Form S-4 is a formal filing with the U.S. Securities and Exchange Commission that companies must submit when proposing a stock-based deal such as a merger, acquisition, exchange offer, or reclassification of shares. It functions like a detailed brochure and roadmap for the transaction, laying out the deal terms, financial data, risks and how shareholders’ ownership will change—information investors use to decide how the deal affects value and whether to vote or sell.

Joint Proxy Statement/Prospectus regulatory

"definitive Joint Proxy Statement/Prospectus will be mailed to stockholders"

A joint proxy statement/prospectus is a single, combined document that both asks shareholders to vote on a proposed transaction and provides the detailed information required when new securities are being offered. Think of it as a combined ballot and product brochure that explains the deal, the companies’ finances, key risks and how ownership will change. Investors rely on it to understand the terms, evaluate risks and make informed voting and investment decisions.

forward-looking statements financial

"This communication includes forward-looking statements (as such term is defined...)"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Letter to Chaparral and Robalo Team Members from Brad Nelson

April 7, 2026 

Chaparral and Robalo Team Members,

I’m reaching out to introduce myself and share a bit about MasterCraft Boat Holdings, Inc., better known to most as MasterCraft, the company behind the MasterCraft, Crest, and Balise brands.

All of us at MasterCraft are thrilled to welcome Chaparral and Robalo into one family as we begin this new chapter together. We’ve long admired what your team has built: two standout brands with passionate followings and established track records of success in recreational boating and sport fishing. Joining our two companies together represents an important milestone not just for us, but for the marine industry as a whole. Together, we’ll be in an even stronger position to shape the future of boating.

A little more about who we are and who I am. MasterCraft, Crest, and Balise serve the premium performance and leisure categories. Our mission is simple: Create superior on-water experiences. MasterCraft is the #1 wake/tow brand in the world. Headquartered in Vonore, Tennessee, our team wakes up every day focused on creating memories that last through differentiated innovation, unrelenting focus on the consumer, and unmatched quality. In many ways, that mission reflects exactly what you already do so well.

With this combination, we see meaningful benefits for our teams, dealers, and customers. With five proven and complementary brands, we’ll offer a broader and more diversified portfolio that can serve a wide range of boaters. Our dealer networks complement each other, with coastal and inland locations helping to extend our reach in key areas. And by sharing ideas from our product development, manufacturing, and purchasing strengths, we’ll have greater scale and capabilities that help us invest in all our brands more efficiently by bringing innovative and meaningful products to market even faster. I’m excited about the opportunity we’ll have to learn from each other, share best practices, and help make each of our brands stronger and more competitive.

Just as important, we know how special Chaparral and Robalo are. We intend to preserve that as well as the strong culture you have built. We anticipate that both brands will continue operating independently as a separate operating unit within the combined company. We expect your identity, teams, dealer and supplier relationships, and operating model to remain in place. Put simply, we don’t expect much to change after the transaction closes.

As for me, I couldn’t be more excited to meet you. I look forward to listening and learning. As an avid boater and outdoorsman, I am a user of the varied and distinct types of boats that we produce. My background is multi-industry, and I am a believer in culture and teamwork.

Our recent announcement was only the first step. We expect the transaction to close in the second calendar quarter of 2026, pending shareholder approval and the completion of customary closing requirements. Until then, both companies will continue to operate separately and independently. It’s business as usual. After close, you can remain focused on the task at hand as you do normally.

You already design, build, and support incredible products and extraordinary brands that resonate with boaters around the world. There is so much to be proud of. We look forward to the opportunity to learn from you, collaborate with you, and build on our shared legacy of excellence, together.

Sincerely,

/s/ Brad Nelson

Brad Nelson

CEO, MasterCraft Boat Holdings, Inc.
