What Turtle Beach Corporation told the SEC could break it.

Turtle Beach is highly customer-concentrated — its four largest customers were ~66% of 2025 gross sales and Walmart, Amazon and Best Buy each represented 14-28% — so losing or reduced orders from a major retailer would materially hurt revenue.

“Our four largest individual customers accounted for approximately 66% of our gross sales in 2025, five individual customers accounted for approximately 69% of our gross sales in 2024, and 69% of our gross sales in 2023.”

Some Turtle Beach products use components and subassemblies for which it qualifies only a single source of supply with long lead times, magnifying shortage, excess-supply, quality and pricing-leverage risks.

“for certain of these items, we qualify only a single source of supply with long lead times, which can magnify the risk of shortages or result in excess supply or decrease our ability to negotiate price with our suppliers.”

Turtle Beach's Bank of America revolving credit facility and term loan are secured by first-priority liens on substantially all assets (receivables, inventory, IP) with financial covenants; a covenant breach could trigger acceleration.

“We have granted Bank of America a lien against substantially all of our working capital assets, including trade accounts receivable, inventories and our intellectual property.”

Substantial 2025 U.S. tariffs (and a new ≥10% Section 2132 surcharge after IEEPA tariffs were struck down) plus China's retaliatory tariffs raised Turtle Beach's costs and pose near-term challenges for its import-dependent gaming-accessories business.

“In 2025, the U.S. government imposed substantial tariffs and trade restrictions on certain foreign goods. In response, certain foreign governments, including China, imposed retaliatory tariffs on certain U.S. goods, which represented near-term challenges to our industry.”
