AMRN Amarin Corp PLC

Amarin Corporation plc (NASDAQ: AMRN), today announced its intent to effect a ratio change on its American Depositary Shares (“ADS”) from one (1) ADS representing one (1) ordinary share, to the new ratio of one (1) ADS representing twenty (20) ordinary shares (the "Ratio Change"). The effective date of the Ratio Change is expected to be on or about April 11, 2025 (the “Effective Date”).​

The ordinary shares of Amarin Corporation (the “Company”) will not be affected by this adjustment. The ADSs will continue to trade on The Nasdaq Capital Market under the symbol “AMRN”.​

The objective of the Ratio Change is to increase the per share market price of the Company’s ADSs to comply with Nasdaq’s $1.00 minimum bid price per share requirement and maintain the Company’s listing on The Nasdaq Capital Market. On the Effective Date, holders of uncertificated ADSs in the Direct Registration System (“DRS”) and in the Depository Trust Company (“DTC”) do not need to take any action, as the exchange of every twenty (20) then-held (existing) ADSs for one (1) new ADS will occur automatically. Registered holders of certificated ADSs will be required to surrender their certificated ADSs to the depositary bank for cancellation and will receive one (1) new ADS for every twenty (20) existing ADS surrendered.

No fractional new ADSs will be issued in connection with the Ratio Change. Rather, fractional entitlements to new ADSs will be aggregated and sold by the depositary bank, and the net cash proceeds from the sale of the fractional ADS entitlements (after deduction of taxes) will be distributed to the applicable ADS holders by the depositary bank.

As a result of the Ratio Change, the trading price of the Company’s ADSs is expected to increase proportionally, but the Company can give no assurance that the trading price per ADS after the Ratio Change will be equal to or greater than twenty (20) times the trading price per ADS before the adjustment.
