Price verdict withheld — value if growth stopped today unreliable
The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $4.8B to $3.0B, decreasing; diluted EPS 11.12 to -15.24, decreasing.
Median gross margin 10.2% over 10y, variable.
Median ROIC 58.5%, above the 12% hurdle in 67% of years.
Net debt/EBITDA 65.4x, interest coverage 0x.
Owner earnings changed trend unclear over up to the ten most recent annual observations.
Price vs. value if growth stopped today
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- Not reported
- Unavailable — insufficient owner-earnings data
- Unavailable — insufficient growth-model data
- Unavailable — no recent price
- No price data
This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. TSEOQ revenue fell in each of the three most recent year-over-year FY comparisons, so this estimate is flagged as unreliable for this company.
Among the current top-score group, the median current price is 255% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

15 years of fundamentals
The business, in plain English
Trinseo PLC booked $3.0B of revenue in FY2025 in the Materials sector and kept 5.6% of it as gross profit — a thin-margin business by that measure. After every other cost, −18.3% of each revenue dollar reached the bottom line.
Across the filed record, revenue shrank from $5.5B (FY2012) to $3.0B (FY2025) — about −4.6% a year compounded over 13 years.
It earned −14.9% on invested capital in the latest filed year, FY2025. Across the full 13-year measurable filed record, median ROIC was 33.4%. Over the v3 recent window (9 measurable filed years), median ROIC was 58.5%. The Returns on Capital filter above scores it 88/100.
The balance sheet carried $2.6B of total debt in FY2025. Balance-Sheet Safety scores it 0/100.
Put together: Returns on Capital is the strongest of the five filters (88/100) and Pricing Power the weakest (0/100), which is how TSEOQ lands at 34/100 — a None moat.
This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.
Exact FY and FY-1 financing invested-capital inputs are required.
The explained ROIC gaps have filed inputs but no meaningful positive invested-capital denominator. Other gaps mean the item is not in the filings for that year. The series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Insider activity
Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”
These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.
This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.
Records still being gathered — partial as of retrieval Oct 16, 2026.
Trailing-12-month totals and the 90-day cluster result are withheld because this issuer walk is incomplete.
No reported Form 4 rows were captured for TSEOQ; the incomplete walk cannot establish zero activity, zero counts, or a negative cluster result.
