How financially healthy is Koss Corp?
Koss Corp (KOSS) scores 66 out of 100 on our Financial Health Score, indicating strong standing within its emerging companies peer group. The score is a 0-100 composite of six dimensions (Cash Runway, Dilution, R&D Intensity, Revenue Progress, Burn Trend, Balance Sheet), each ranked as a percentile relative to companies in the same scoring family (banks against banks, REITs against REITs, and so on) rather than across all industries. It rates the quality of the business, not whether the stock is fairly priced, and is not financial advice. Learn more in our complete guide to financial health indicators.
