Fair value as of: Jul 21, 2026
From 2 valuation models · updated 20 days ago
Fair value updated Jul 21, 2026, revised from $7.76 to $0.4600 (−94.1%) since Jun 25, 2026. Share price −1.3% over the past month.
Below-average quality, and screening another 42% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($0.6280). The favourable scenario is already priced in.
- Weak quality (32/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range ($0.2940 to $0.6280) leaves room in how you read the outcome.

Analysis
Trinseo PLC (TSE) currently trades at $0.7900, while our model-based Fair Value estimate is $0.4600, implying the stock looks roughly 41.8% overvalued today. The Quality Score stands at 32/100 (below-average quality), in the Basic Materials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Over the trailing twelve months, Trinseo PLC generated revenue of $3.1B at a net margin of -13.2%. Revenue declined 14.3% year over year. Net debt stands at $126M. Fundamentals as of Jul 21, 2026
Our scenario range runs from $0.2940 (bear case) to $0.6280 (bull case); at $0.7900, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 78% below its 52-week high, currently below its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -58% fair-value upside, at -42%, TSE screens cheaper than that median.

A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
