Fair value per share

Under review: every model's value for OIO Group is far from the share price, which usually points to a data problem (a merger, a share-count change, a one-off) rather than a bargain or a bubble.

Highlights

How we pick these

Strengths

Nothing in OIO Group's latest figures clears our strength thresholds.

Things to watch

  • Revenue shrinking. Revenue fell 4.4% over the last 12 months.
  • Burning cash. Free cash flow was -15.2% of revenue over the last 12 months.
  • Heavy stock-based pay. Stock pay equals 21.2% of revenue, against a median of 0.7% for environmental & facilities services companies we cover: a real cost that cash-flow figures leave out.
  • Share dilution. Diluted shares rose 61.2% in a year.
  • Growth easing. The growth rate is 3.4 points lower than a quarter earlier.
  • Below peers: net margin. Net margin of -81.6% ranks 16 of 17 environmental & facilities services companies we cover (median 0.7%).
