Biodexa Pharmaceuticals PLC (“Biodexa” or the “Company”)
ADR Ratio Change
Biodexa Pharmaceuticals PLC (Nasdaq: BDRX), a clinical stage biopharmaceutical company developing a pipeline of innovative products for the treatment of rare diseases with unmet medical needs, today announces a ratio change on its American Depositary Receipts (“ADR”) from one (1) ADR representing one hundred thousand (100,000) ordinary shares, to the new ratio of one (1) ADR representing five hundred thousand (500,000) ordinary shares (the "Ratio Change"). The effective date of the Ratio Change is expected to be on or about April 6, 2026.
Pursuant to the Ratio Change, ADR holders will be required on a mandatory basis to surrender their ADRs for cancellation and exchange to receive one (1) new ADR (New CUSIP: 59564R872) for every five (5) old ADRs (Old CUSIP: 59564R880). No fractional ADRs will be allocated. The aggregate fractions, if any, will be sold and the net proceeds will be distributed to the entitled ADR holder. The Company's Depositary, JP Morgan Chase Bank, N.A. will contact ADR holders and arrange for the exchange of their existing ADRs for new ADRs.
For ADR holders, the Ratio Change will have the same effect as a one-for-five reverse ADR split. The ordinary shares of Biodexa will not be affected by this change.
The Ratio Change is aimed to bring the price of the Company’s ADRs into compliance with the Nasdaq $1.00 minimum bid price per share requirement, although Biodexa can give no assurance that the Ratio Change will be effective in achieving this goal.
