KOSS

Koss is a subscale ($12.6M revenue) headphone brand whose operating business does not make money. FY2025 revenue rose 2.9%, but that's off a structurally lower base — sales have fallen from $19.5M in FY2021 to $12.6M today. Operating income was -$1.74M (-13.8% margin) and net income -$875K, the second consecutive annual loss after FY2024's -$951K. Critically, the only thing keeping the pre-tax loss to -$857K is $879K of interest income on the cash pile; strip that out and the core operation loses roughly $1.7M a year. FY2023's $8.32M 'profit' was a one-off patent-litigation windfall, not earnings power, so the run-rate is a loss-making operation dressed up by investment income.

The balance sheet is genuinely strong — $30.6M equity, just $6.57M liabilities, current assets of $22.6M against $1.94M current liabilities (an ~11x current ratio) and no meaningful debt — which is why this is a 'sell,' not an 'avoid': there is real asset backing and no solvency risk. But that backing doesn't justify the price. At $37.5M market cap the stock trades at ~1.2x book and 3.0x sales for a business with negative operating margins and negative operating cash flow (-$215K). You're paying a premium over net asset value for the privilege of owning a money-losing operation, and R&D of just $214K (down 10%) signals no product-led re-acceleration is being funded.
