What matters now
The price sits above even our optimistic bull case (£0.3400). The favourable scenario is already priced in.
The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
Solid but not exceptional quality (47/100) and above fair value, neither a clear bargain nor a standout compounder.
Price vs Fair Value (5 years)
White line = price, green steps = our fair value per fiscal year, dashed = 300-day average. As of Aug 20, 2026.
How to read this chart
60‑month range £0.7845 – £2.01 · fair‑value band £0.2000 – £0.3400 · the £0.7845 price screens above the £0.2600 fair value. Green steps = our fair value per fiscal year (point-in-time, no hindsight). Dashed = 300-day average. As of Aug 20, 2026.
Ibstock PLC (IBST) currently trades at £0.7845, while our model-based Fair Value estimate is £0.2600, implying the stock looks roughly 201.8% overvalued today. The Quality Score stands at 47/100 (below-average quality), in the Basic Materials sector. Bull case: the Asset-Based group reads highest at a median of £0.6500 per share, and 1 of the 14 models we run sit above the £0.7845 price. Bear case: the Earnings-Based group reads lowest at £0.0800, and 13 of the 14 models stay below the price. Evidence for this calculation is low.
Over the trailing twelve months, Ibstock PLC generated revenue of £372M at a net margin of 0.8%. Revenue declined 5.0% year over year. It earns a return on equity of 0.8%. Net debt stands at £150M. Fundamentals as of Aug 20, 2026
Scenario range: £0.2000 (bear) to £0.3400 (bull), the price of £0.7845 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target. For context, the median of 10 Basic Materials peers we cover trades at −56% fair-value upside, at −67%, IBST screens richer than that median.
