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.
Solve the discounted cash flow backwards, then stress-test the assumptions.
Average free cash flow across the last 3 positive fiscal years (FY2019, FY2020, FY2021). Smooths the cycle. Stock compensation is NOT charged — it is added back inside operating cash flow.
To be worth $5.78 today, the market must believe free cash flow compounds 1.7%/yr for a decade (off $1.6M on the 3-yr avg basis).
On the basis ($1.4M) the requirement is 3.6%/yr. Shares issued to employees are added back in operating cash flow, so this basis treats them as free.
The market's 1.7% is more optimistic than its 9-yr track record.
Default is 8.7% — this company's computed cost of capital (computed WACC), the same rate the Analysis tab discounts at.
2-stage DCF · 0.01B shares (market data) · net debt -$6.5M
mean 93.2% · volatility σ 373% · implied rate exceeded in 3/6 yrs
Central path = implied 1.7%/yr growth; shaded band = ±1σ (373%) 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.
What the company returns to shareholders — and whether it's covered by cash.
The dividend exceeds free cash flow (407%) — funded from the balance sheet or debt, a red flag if it persists. Last year: $1.9M dividends + $0 buybacks = $1.9M returned on $475K FCF.
1 consecutive years of dividend increases.
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.
Reinvestment has been productive — operating income grew well per dollar put in. Current ROIC on all capital: 11%. 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.

ROE 12% against ROIC 11% — 1% of the return on equity comes from leverage and buybacks rather than from the operating business.

The metrics that matter, over time
A 30-second read on AATC: price, valuation and headline fundamentals from SEC filings. The four questions at the top of the page are where the judgements live.
How much the company owes, how it's trended, and how comfortably it's serviced.
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Interest is easily covered by operating profit. Effective rate ~0.8% on $923K of debt. Interest last disclosed in FY2020 (no longer broken out).
Cash of $8.2M fully covers short-term debt of $56K.
Mostly long-term debt (balance-sheet current vs non-current split). A year-by-year maturity schedule wasn't disclosed for this issuer.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Educational — not a recommendation.

Return on equity (12%) and return on invested capital (11%) are within a couple of points in FY2021, so the headline return is the operating return — there is no meaningful leverage effect to strip out.
Margins have compressed 2 years running even as the spread stayed positive.
Converts 0.97x of reported profit into cash — adequate, without much margin.
Reported free cash flow is $475,000; after share-based compensation it is $249,000. The difference is a real cost that the cash flow statement adds back.
Debt is present but there is no positive EBITDA or no reported interest expense, so coverage cannot be measured.

SBC is added back inside operating cash flow, so reported free cash flow treats shares issued to employees as free. Percent of revenue says how expensive the payroll is; percent of operating cash flow says how much of the cash exists only because the charge was added back. The buyback offset is buybacks over SBC — below 1.0 the repurchase does not cover the shares issued.
Figures are the latest fiscal year (FY2021) from the company's own filings, not a trailing-twelve-month window — Q2 reads fiscal years throughout so the cash-conversion ratios and these share one basis. A blank is a line the filer did not report; it is never read as zero.
