What Malibu Boats, Inc. told the SEC could break it.
Malibu Boats' disclosures cluster on concentration and input costs at both ends of its manufacturing. Its sales lean heavily on a few dealers — those under common control of OneWater Marine were about 24.7% of consolidated net sales in fiscal 2025 (up from 17% two years earlier), and its top ten dealers were half to two-thirds of each segment's sales — so a major dealer's loss or distress would hurt results. On the supply side, several key components such as GM engines, windshields, electrical parts and gel coats come from sole or limited suppliers that are hard to replace, and roughly 18-20% of its cost of sales is sourced abroad, leaving it exposed to new tariffs it expects to add about 1.5-3% to cost of sales in fiscal 2026, on top of volatile resin, fiberglass and vinyl prices.

In its own words
What could break it.
Customer concentration
- OneWater Marine dealers = 24.7% of consolidated net sales; top-10 dealers 51-66% per segmenthigh
Malibu's sales are concentrated in a few dealers — dealers under common control of OneWater Marine were ~24.7% of consolidated net sales in FY2025 (up from 17.2% in 2023), and the top-10 dealers were 51-66% of each segment's sales — so loss or financial distress of a major dealer would materially hurt results.
“Sales to our dealers under common control of OneWater Marine, Inc. represented approximately 24.7%, 23.7% and 17.2% of consolidated net sales in fiscal years 2025, 2024 and 2023, respectively,”
SEC filing →As of 2025
Regulatory & policy
- tariffs on imported inputs (18-20% of COGS offshore; +1.5-3% COGS tariff exposure expected FY2026)high
Malibu estimates 18-20% of its cost of sales is sourced outside the U.S. and expects new tariff exposure to add approximately 1.5%-3% of cost of sales in fiscal 2026, materially raising input costs amid an uncertain trade environment and retaliatory countermeasures.
“We estimate that 18-20% of our cost of sales are sourced from outside the United States and thus we have the potential to be materially impacted by tariffs in future periods.”

Sole-source dependency
- engines (GM), windshields, electrical components and gel coats from sole/limited suppliershigh
Several key components — including GM engines, boat windshields, certain electrical components and gel coats — come from sole or limited suppliers; replacing them is difficult and a sole supplier could exert pricing/warranty leverage, with Malibu having incurred $2.6M securing extra engine blocks amid shortages.
“Some components used in our manufacturing processes, including engines, boat windshields, certain electrical components and gel coats are available from a sole supplier or a limited number of suppliers.”
SEC filing →As of 2025
Commodity & input dependence
- raw-material price exposure (resins, fiberglass, vinyl)low
Malibu relies on a global supply chain for raw materials including resins, fiberglass and vinyl, plus parts and components; volatile prices for these inputs (amid inflation) directly drive its material and labor costs and gross margin.
“We rely on a global supply chain of third parties to supply raw materials used in our manufacturing process, including resins, fiberglass, and vinyl, as well as parts and components. The prices for these raw materials, parts, and components fluctuate depending on market conditions”
