Koss Corporation reported modest sales growth but wider losses for the quarter ended March 31, 2026. Net sales for the quarter inched up to $2.8 million, with stronger U.S. demand and direct-to-consumer sales offset by sharply lower export revenue. For the nine months, sales reached $9.8 million, helped by education and distribution orders.
Gross margin fell to 35.5% from 39.0% as tariffs and earlier high freight costs pressured profitability, leading to a nine‑month net loss of $868,265. Koss reclassified about $17.0 million of U.S. Treasury securities to available-for-sale to support a diversification-by-acquisition strategy. The company ended the period with $1.9 million in cash, $17.0 million in liquid investments, no borrowings on a $5 million credit facility, and significant tax loss carryforwards.

Basic and diluted loss per share doubled to $0.06.
For the first nine months, net sales increased 2.3% to $9.76 million, while the net loss widened to $868,265. Gross margins fell from 38.4% to 35.5%, pressured by higher-tariff Chinese inventory and earlier elevated freight costs. Management highlighted 23% year-over-year growth in higher-margin direct-to-consumer sales, now the largest segment, partially offsetting weaker European demand.
Koss Corporation President and CEO Michael J. Koss, who is also a director and more than 10% owner of KOSS, reported a trust-related transfer involving 12,000 shares of common stock on February 17, 2026.

Koss Corporation reported a weaker quarter ended December 31, 2025. Net sales fell to $2.9 million from $3.6 million, mainly because prior-year European new product orders did not repeat, while domestic sales grew modestly and an education customer drove first-half growth.
Gross margin dropped to 29.0% from 39.5%, pressured by high tariffs on China-sourced inventory, some as high as 145%, and slightly higher freight. Selling, general and administrative costs rose to $1.8 million, largely from $250,000 of patent-related legal expenses that fully offset a $250,000 licensing gain, resulting in a net loss of $565,407, or $0.06 per share.
The company ended the quarter with $2.5 million in cash, $13.0 million in short-term U.S. Treasury investments, $4.0 million in long-term Treasuries and an undrawn $5.0 million credit facility, supporting liquidity despite ongoing macroeconomic, tariff and supply chain uncertainties.
