Johanna Frisch

All filings by Johanna Frisch on record concern Trinseo PLC, in the capacity of finance chief. Over a trading history stretching from 16 February 2022 to 30 September 2025, the count stands at 12 filings.

Every open-market trade on record is a purchase: 3 purchases worth €14k, and no sale. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Other entries cover 9 share grants. Since January 2025: 3 purchases and no sales on the market.

Half of the purchases are above €4,706 and half below. Across 3 purchases, this insider has always bought alone, with no colleague buying within 30 days. For 3 purchases whose 90-day window has closed, the share price was higher on day 90 than the day after publication in 0% of cases, with a median move of -23.6%. They describe history only and say nothing certain about the share price ahead.

Most recently, on 2 October 2025, the filings show a share grant worth €4,393 in Trinseo PLC. The clock since the last published purchase (14 March 2025) now reads 590 days. Typically, a trade is published a median of 2 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
