Our note on each quarter Koss files

10-Q filed October 30: Koss

Koss Corp's revenue over the twelve months to September 2026 came in at $12m, a 10.7% decline on the prior year. That marks a sharp reversal from the 3.1% growth recorded just a quarter earlier. Profitability has deteriorated alongside the top line: free-cash-flow margin slid to -13.4%, down from 1.6% a year ago, while the operating margin widened its loss, narrowing to -15.5% from -8.5%. Despite this weaker trajectory, our model value has barely moved, sitting at $2.15 a share. That figure remains well below the current share price of $3.39, leaving the stock looking expensive relative to fundamentals. The rating stays Sell.

The Fundamentalytics view

Next results ~January 28, 2027 (estimated)

Koss Corp's trailing-twelve-month revenue fell 10.7% year on year, with a free-cash-flow margin of -13.4%. Where it stands out: stock pay as % of revenue of 0.5% ranks 1 of 9 consumer electronics companies we cover. Where it lags: change in growth rate of -13.9pp ranks 9 of 11 consumer electronics companies we cover.

Our discounted-cash-flow model values the business at ~$2.1 per share in the base case (~$2.1–$2.2 across growth scenarios) — model values under stated assumptions, not a price target.

Current signal Revenue growth decelerating: TTM revenue growth slowed to -10.7% (-13.9pp vs the prior quarter), the 4th consecutive quarterly slowdown.

Valuation

Koss Corp valuation models and calculator

What the price is pricing in

The share price implies about 40.4% a year of cash-flow growth for five years.That is faster than the -7.4% a year revenue growth Koss has delivered.

Read with care: free cash flow has swung sharply in the past year (often a one-off tax, legal or working-capital item), so the cash-flow base behind this reading may be unusually low or high.

  • Priced in40.4%
  • Last 12 months-10.7%
  • 3 years a year-2.8%
  • 5 years a year-7.4%

Our cash-flow model with every input fixed except growth over the next five years, solved for the growth at which the model value equals the share price ($3.20, Nov 3, 2026). Cash-flow growth then fades to 2.5% a year; discount rate 8.5%. Delivered figures are revenue growth from SEC filings.

How we got here: a discounted-cash-flow model of Koss Corp's free cash flow after stock-based pay with after-tax interest added back ($89,834, FY2027 Q1 TTM), growing 4% a year for five years and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$2.1–~$2.2 ; that spread sets a 15% margin before we rate Buy or Sell.

Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Koss Corp's free cash flow after stock-based pay ( $89,834, FY2027 Q1 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Koss Corp as an operating company, with every model that fits that kind of business. Cost of equity 11%: the 10-year Treasury yield (4.9%) plus a beta of 1.35 times a 4.5% equity risk premium.

Value per share by model
Model Value per share In the combined value?
Cash-flow model (DCF) Free cash flow to the firm (after stock pay, with after-tax interest added back), grown then faded to 2.5%, discounted at 8.5% as the firm rate, less debt and other claims. ~$2.1 ~$2.1–$2.2 Primary model, counts double
Price-to-earnings vs peers Earnings per share times peers' typical (harmonic-mean) price-to-earnings. — Does not apply: no positive earnings in the latest twelve months
Residual income Book value plus the present value of returns above the cost of equity, fading over ten years. ~$1.8 ~$1.3–$2.5 Included
Justified price-to-book Book value times (return on equity - growth) / (cost of equity - growth): steady-state returns. ~$1.1 ~$1.0–$1.3 Included
Combined value Weighted average of the models that apply: the primary model (cash-flow model (dcf)) counts double. Models more than 5x or less than 0.2x the share price, or more than 3x away from the other models' median, are left out. ~$1.8 ~$1.1–$2.1 3 models

Different models fail in different ways, so where several apply we average them rather than trust one.

Moat

30 /100

Weak moat

How hard Koss's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 0 / 20

    Cash operating profit has been a median -3.6% of total assets over 10 years.

  • Pricing power 10 / 20

    Gross margin has been a median 34.3%, moving by 4.4 percentage points (standard deviation) across 10 years.

  • Durability 10 / 20

    Operating margin has been a median -12.0%; its worst year was -128.0%.

  • Cash conversion 5 / 20

    Free cash flow was positive in 5 of 10 years, at a median 0.6% of revenue.

  • Discipline 10 / 20

    The diluted share count rose 27.5% over five years; stock-based pay has been a median 2.4% of revenue.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (35 before it).

Source: SEC EDGAR XBRL company facts (US and foreign periodic filings); column headings link to the filing. EBITDA is operating income plus depreciation and amortisation. Free cash flow is cash from operations minus capital spending. Growth is left blank when last year's figure was a loss or under 2% of revenue. Share counts and EPS are restated for stock splits. A dash means the company didn't report the figure.
