Fair Value models

Price $29.50 · Downside -46.4%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. Based on fiscal year 2025 figures (about 10 months old). Earnings retained since then ($0.1881 per share) are deliberately not added.Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds.Coverage ⓘCoverage = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Growth Forecast
A lot of optimism in the price
The price assumes more growth than the company has delivered so far and more than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+18.5%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+14.7%
Yearly sales growth analysts expect, extended to five years.
After inflation (USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about +15.8% a year for the price and +12.0% for the forecasts.
News mood ⓘNews mood, the average tone of recent news (92 articles), rated against how stocks are usually covered. 🚀 Hype = unusually upbeat · 🙂 Positive = above average · 😐 Neutral = typical · 🙁 Negative = below average · 😨 Very negative = unusually downbeat. It reflects the tone of coverage, not our valuation.Hype
Recent news coverage is unusually upbeat, far more positive than stocks are typically covered.
AI conclusion: The business benefits from long-term government contracts that add predictability to cash flows in fire safety systems, yet sustained net losses and negative ROE underline persistent profitability weaknesses.
Main risk: Seasonal wildfire patterns and acquisition integration issues drive swings in results, hitting demand for fire retardants and overall cash flow stability.
Perimeter Solutions blends seasonal demand for fire retardants with steadier specialty chemicals and acquired fire safety systems on government sites. Long-term contracts there add some predictability to cash flows, yet wildfire patterns and integration still drive swings in results. Will these niches deliver steadier performance than the headline volatility suggests, or will seasonal and external factors keep dominating?
