Solve the discounted cash flow backwards, then stress-test the assumptions.
To be worth $23.82 today, the market must believe free cash flow compounds -1.2%/yr for a decade (off $146M normalized FCF).
The market's -1.2% is more conservative than its 9-yr track record.
2-stage DCF · 0.05B shares · net debt $450M
mean 1391.2% · volatility σ 3970% · implied rate exceeded in 4/8 yrs
Central path = implied -1.2%/yr growth; shaded band = ±1σ (3970%) 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.
Total shares institutions bought (green) vs sold (red) each quarter across all holders.
Inferred from quarter-over-quarter change in each fund's 13F position (new stakes count as buys, exits as sells). Not tick-level trades.
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.

Ranked against 1085 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 AMPH's sector (Healthcare) 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.
Is the value real, and is the business safe? Academic scores + earnings quality + solvency, from SEC filings.
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.
Earnings are backed by cash (FCF ≥ net income) — high quality. Lower/negative accruals = higher quality (Sloan).
Comfortably covers interest; leverage rising year-over-year.
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 + $76M buybacks = $76M returned on $121M 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 balanced mix of reinvestment and shareholder returns.
Reinvestment has been productive — operating income grew well per dollar put in. Current ROIC on all capital: 7%. 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.
Cash of $170M covers the $234000 due within a year 727.3× over. Scheduled principal only (excludes interest & revolver draws). As of 2023-12-31 (10-K).
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Coverage is adequate but not comfortable. Effective rate ~4.1% on $620M of debt.
Cash vs short-term debt unavailable.
Mostly long-term debt (balance-sheet current vs non-current split). See the maturity ladder above for the year-by-year repayment schedule.
Debt, cash, interest and equity from the SEC balance sheet & income statement. Effective rate = interest ÷ average debt. Maturity ladder from the SEC long-term-debt repayment schedule. Educational — not a recommendation.

Watch the leverage lever — a chunk of ROE comes from the balance sheet.
What the company owes vs. what it holds
Year-by-year maturities aren't in SEC companyfacts (footnote-only), so this shows the debt/cash structure and net leverage instead.
Latest year: profit growth vs revenue growth
High operating leverage: profit moved 19.2× as fast as sales — great in an upturn, painful in a downturn.
