The thesis, from the filings

Trinseo PLC earns about -6% on invested capital, and has bought back 10% of its shares over 5 years. The cash-flow models don't apply cleanly here — the ledger says why below.Whether it’s worth owning at today’s price is the last question — and yours to answer, below.

iii. Is this a good business?
Moat signal · return on invested capital
-6% avg · 5y
FY21 5%FY22 -8%FY23 -12%FY24 -6%FY25 -10%

seeing a moat in the numbers →
Management signal · capital allocation
−10% shares · 5y
