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 $109.1M 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: -12%. 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.
$0 of principal comes due within a year. Scheduled principal only (excludes interest & revolver draws). As of 2015-06-30 (10-Q). The cash figure is from 2025-12-31, so the two are not the same balance-sheet date — the schedule has not been refiled since.
Insufficient EBITDA/debt history.
Green ≤ 1.5× · amber ≤ 3× · red > 3× (leverage relative to cash earnings).
Thin coverage — earnings barely cover interest. Effective rate ~5.1% on $80.3M of debt.
Cash vs short-term debt unavailable.
Mostly short-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.
A reverse discounted cash flow is not shown for a company with no positive EBITDA.
No positive EBITDA in the recent record, so there is no return on capital to compare against its cost.
Classified from the filings: EBITDA negative in each of the last 2 years.
Ranked against 11 sector peers with collected financials. Valuation from latest close × latest fiscal-year fundamentals; 13F conviction as of 2026-09-30.
Percentile is “goodness” within the peer set (100 = best). For valuation and leverage that means cheaper / less-levered ranks higher.

Above 0 = ahead of the S&P 500 since the window start; below 0 = behind. Rising means it's pulling ahead.

DuPont — the three levers
ROE -12% against ROIC -12% — -1% of the return on equity comes from leverage and buybacks rather than from the operating business.
Equity is the year-end figure. On average equity over the two year-ends, ROE is -14.3% — the two diverge when buybacks or issuance move equity during the year.

A 30-second read on NTRA: price, valuation and headline fundamentals from SEC filings. The four questions at the top of the page are where the judgements live.
No positive operating income in the last three years, so there is no return on capital to compare against its cost.

Fewer than three profitable years with a cash flow statement, so cash conversion cannot be judged.

Missing from our data, so excluded from this answer: 3 years of cash flow.
Debt is present but there is no positive EBITDA or no reported interest expense, so coverage cannot be measured.
This schedule comes from a filing dated 2015-06-30, 4141 days old. Maturities are shown relative to that date, not to today.
Ladder as of 2015-06-30 (10-Q); cash from the 2025-12-31 balance sheet; FCF from FY2025. No cash figure on the matching balance sheet, so no coverage line is drawn.

Once stock compensation is charged, free cash flow averages -$225M over the last 2 years — there is nothing left to discount, so no growth rate can be solved for. Before the charge it averages $89M.

Every row is classified by what it MEANT, not by its SEC code. A code is not a meaning: code P (“purchase”) also covers dividend reinvestment and employee stock purchase plans, and code S (“sale”) also covers 10b5-1 plan sales scheduled months earlier and option exercises sold the same day.
Across 30 days of all filings, $5.08bn of insider selling contained $3.50bn of plan sales and $0.46bn of exercise-and-sell. Only 29% was discretionary. Reading an unclassified feed badly overstates how much insiders decided.
Buys and sales are counted separately and never netted. They are different decisions by different people; a company where one officer bought while another sold is not “neutral”.
The holding line carries each insider's last reported position forward, so it shows the total held rather than a sawtooth of whoever traded that day. It covers only insiders who filed in the window.
“Filed late” counts calendar days past the two-business-day deadline with five days' grace, so a Thursday or Friday trade crossing a weekend is never flagged. It describes the company's filing discipline, not the trade.
Insider activity is descriptive. Nothing here is investment advice.
