Amarin Corporation plc (NASDAQ: AMRN) said on April 9, 2025, that its previously announced change to the ratio of its American Depositary Shares (ADSs) will take effect on April 11, 2025. Each ADS will represent twenty ordinary shares, instead of one ordinary share.
The company says the goal is to raise the per-share price of its ADSs to meet Nasdaq's $1.00 minimum bid price requirement and keep its listing on The Nasdaq Capital Market. Amarin can give no assurance that the ADS price after the change will equal or exceed twenty times the price before it.
Holders of uncertificated ADSs in the Direct Registration System and at the Depository Trust Company do not need to act. The exchange of every twenty existing ADSs for one new ADS happens automatically. Holders of certificated ADSs must surrender them to the depositary bank for cancellation and will receive one new ADS for every twenty surrendered.
No fractional new ADSs will be issued. The depositary bank will aggregate fractional entitlements and sell them, then distribute the net cash proceeds after taxes to the holders. The ordinary shares are not affected, and the ADSs will keep trading on The Nasdaq Capital Market under the symbol "AMRN".
