Trinseo Announces Quarterly Dividend

Trinseo (NYSE: TSE), a global materials solutions provider and manufacturer of plastics, latex binders and synthetic rubber, today announced that its Board of Directors authorized a quarterly dividend of $0.40 per share. The dividend will be a cash distribution payable on October 22, 2020, to shareholders of record as of the close of business on October 8, 2020.

Tax Considerations

Trinseo is a public limited liability company formed under the laws of Luxembourg. Under current Luxembourg tax law, distributions to shareholders via repayments of equity or share premium are not subject to Luxembourg withholding tax. Distributions made by Trinseo before 2020 were repayments of equity or share premium and were therefore not subject to Luxembourg withholding tax.

This quarterly distribution will be considered a dividend made on the common shares and is subject to a 15% withholding tax under Luxembourg law. Trinseo will deduct this tax from the dividends paid to our shareholders and transfer this tax to the Luxembourg tax authorities.

Certain exemptions or reductions in the withholding tax may apply to shareholders based on Luxembourg tax legislation or applicable income tax treaties. Shareholders should consult their own tax advisors regarding the ability to claim any available refunds from the Luxembourg tax authority. Trinseo S.A.’s RCSL number is B153549.

The above discussion does not cover all tax matters that may be of importance to any particular shareholder and may not be relevant to every investor. Shareholders are strongly urged to consult their own tax advisors about the tax consequences of Luxembourg withholding taxes, the availability of exemptions or benefits under tax treaties, or other U.S. federal, state, local and foreign tax considerations relating to dividends issued by Trinseo, or the acquisition, ownership and disposition of our ordinary shares.
