Cash vs value: 2%; Cash as a share of company value
Debt vs value: 1%; Debt as a share of company value

From RBRK's last IEX trade and its SEC filings (profits and sales over the last four quarters). A starting point for research, not a verdict.

Price these guesses point to$21.57-84% vs $133.44 todayAbout -31% a year, before dividends

What today's price needs: with a 6% margin and a 15x P/E, sales would have to grow about 87% a year for 5 years just to match today's price.

Simple math on your guesses, not a forecast or a price target. Real results depend on many things these sliders leave out.

Insider rating

43Mixed

Pre-planned sales of $6.4M (weaker signal)

50 is neutral. Buying by more insiders, top executives and bigger stakes raises it. Selling lowers it; pre-planned sales count less.
