What this company does
Koss designs and sells stereo headphones and audio accessories, ranging from consumer earbuds to professional studio and communication headsets. Product sales to retailers, distributors, and direct consumers generate essentially all revenue, totaling roughly $9.8 million over the past nine months. The company is operating at a loss, with widening operating deficits offset largely by interest income on its $17 million investment portfolio, leaving the underlying headphone business unprofitable.
Generated from KOSS's filing dated 2025-08-29
Key risks
- Operating losses widening: nine-month loss from operations grew to $1.78M from $1.30M, with gross margin compressing as COGS outpaced flat ~2% sales growth.
- Cash burn: operating cash flow swung to -$581K from +$320K YoY; cash fell to $1.9M, with profitability dependent on $670K interest income from investments.
- SG&A deleverage on stagnant revenue: SG&A rose to $5.24M (54% of sales) on only $9.76M nine-month revenue, eroding any path to operating profitability.
