Hmm, we can't give any reliable projection for Ironwood Pharmaceuticals's growth rate. The company either has too few years of historical data for us to examine, or it's in the habit of losing money.

None of this means it's a bad stock. Maybe it's new and growing quickly, or maybe it's turning things around. We can't say anything sensible about it, so we won't say it's obviously undervalued right now. Proceed at your own risk!

Year-to-year variability in free cash flow is volatile, measured at 71%.

Our value investing guide explains how to test these numbers against the filings themselves.

Compared With Its Sector and Industry

Its trailing P/E ratio is 74% below the average for stocks in the Healthcare sector.

Its trailing P/E ratio is 100% below the average for stocks in the Drug Manufacturers - General industry.

A P/E ratio depends on trailing earnings, which one-time items can distort, so a lower P/E is not by itself evidence of value.

Every fiscal year on this page is reported by one SEC filer, CIK 1446847.

Each figure on this page comes from that filer.

Risks to This Analysis

  • Free cash flow was negative in 10 of the 17 years we have.
  • Free cash flow is volatile from year to year, so the estimates depend heavily on which years are included.
  • We have no value estimate for this stock, so no price comparison is made.
  • These figures are automated calculations from SEC filings and the recent price. They may contain errors, and they do not reflect lawsuits, management changes, or other events the filings do not show.
