How a revenue dollar becomes profit — FY2025
Each value shows its share of revenue below it (common-size).

Source: SEC EDGAR XBRL filings (annual, fiscal year). Quarterly flow items are derived from cumulative filings; balance-sheet figures are as-of each period end. Ratios and margins are computed, not reported.
Solve the discounted cash flow backwards, then stress-test the assumptions.
To be worth $3.53 today, the market must believe free cash flow compounds -21.5%/yr for a decade (off $11M normalized FCF).
2-stage DCF · 0.01B shares · net debt -$3M
mean -38.8% · volatility σ 87% · implied rate exceeded in 2/4 yrs
Central path = implied -21.5%/yr growth; shaded band = ±1σ (87%) of this company's historical FCF volatility, widening with time. The wider the band, the less certain the growth.
Reverse DCF: rather than guessing a fair value, we solve for the growth the current price implies, then you stress-test the assumptions. Enterprise value of the FCF stream, less net debt, ÷ shares. Educational — not a recommendation.
Is the value real, and is the business safe? Academic scores + earnings quality + solvency, from SEC filings.
4/8 of the 9 checks — 1 couldn't be scored (see above), so the score is out of the 8 with data.
Safe > 2.99 · grey 1.81–2.99 · distress < 1.81
Eight indices comparing this year to last (receivables, margins, asset quality, growth, accruals, leverage). Above −1.78 suggests possible manipulation; below −2.22 is clean.
A screen, not proof — high growth alone can raise it.
Cash-conversion data unavailable. Lower/negative accruals = higher quality (Sloan).
Coverage data unavailable.
F-Score (0–9 fundamental momentum), Altman Z (distress risk), and Beneish M (earnings-manipulation screen) are academic models computed from the SEC filings. Screens and context — educational, not recommendations.
What the company returns to shareholders — and whether it's covered by cash.
No dividend to cover. Last year: $0 dividends + $0 buybacks = $0 returned on -$705625 FCF.
Yields use the latest fiscal-year dividends/buybacks over current market cap. Dividends and buybacks from the SEC cash-flow statement; payout coverage vs net income and free cash flow. Educational — not a recommendation.
How management deployed cash over 10 years — and what it earned on reinvestment.
A reinvestment story — most cash went back into growth rather than to shareholders.
Operating income fell despite reinvestment — a warning on capital productivity. Current ROIC on all capital: -3%. Rough measure (includes maintenance capex).
Cash uses aggregated from the SEC cash-flow statement over 10 fiscal years. "Return on reinvestment" is a rough proxy — operating-income change ÷ cumulative CapEx + M&A — and includes maintenance capex. Educational — not a recommendation.
How much the company owes, how it's trended, and how comfortably it's serviced.
Insufficient EBITDA/debt history.
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Thin coverage — earnings barely cover interest. Interest last disclosed in FY2018 (no longer broken out).
Cash vs short-term debt unavailable.
Short-term / long-term split not separately reported.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Educational — not a recommendation.
Total return (dividends reinvested) vs the market, from quarter-end prices.
Above 0 = ahead of the S&P 500 since the window start; below 0 = behind. Rising means it's pulling ahead.
How far the stock fell below its prior peak. Deeper, longer drawdowns = a rougher ride to the same return.
Quarter-end, dividend-adjusted (total return). Beta & volatility from quarterly returns (annualized). Benchmark is the S&P 500 (SPY total return). Annual returns compound the quarters ending in each calendar year; the first and last years in a window may be partial. Past performance doesn't predict future results.

The metrics that matter, over time
A 30-second read on KOSS: price, valuation, headline fundamentals, and an auto-generated scorecard from SEC filings. Flags are rule-based signals, not recommendations.
Ranked against 743 sector peers with collected financials. Valuation from latest close × latest fiscal-year fundamentals; 13F conviction as of 2026-03-31.
Percentile is “goodness” within the peer set (100 = best). For valuation and leverage that means cheaper / less-levered ranks higher.

Peers = companies sharing KOSS's sector (Technology) with collected SEC financials. Multiples use the most recent end-of-day close and latest fiscal-year fundamentals (trailing, not forward). Missing cells mean the peer never reported that line item, has no collected price, or has a non-positive denominator. Not investment advice.
