MasterCraft Boat Holdings is supplementing its Joint Proxy Statement/Prospectus regarding the proposed merger with Marine Products Corporation. The supplement addresses shareholder demand letters and two identical lawsuits filed in New York Supreme Court alleging misrepresentation in the original proxy. MasterCraft denies all allegations but is providing additional disclosures to moot the claims and minimize litigation costs. The filing includes updated financial analysis, including revised discount rates (10.8% to 11.5% for DCF) and additional context on historical outreach to Marine Products. The MasterCraft board continues to unanimously recommend that shareholders vote FOR the merger proposals.
