Biodexa Pharmaceuticals (Nasdaq: BDRX) announced an ADR ratio change from 1 ADR = 100,000 ordinary shares to 1 ADR = 500,000 ordinary shares, effective on or about April 6, 2026. ADR holders must surrender five old ADRs for one new ADR (New CUSIP: 59564R872).

The change will operate as a one-for-five reverse ADR split for ADRs only; ordinary shares are not affected. The depositary, JP Morgan Chase Bank, N.A., will manage exchanges and sell any aggregate fractional interests, distributing net proceeds. The Company said the change aims to comply with Nasdaq's $1.00 minimum bid requirement but gave no assurance it will achieve that outcome.

Recent Company History

Over the past few months, Biodexa reported several pipeline and corporate milestones alongside capital markets activity. A December 18, 2025 public offering of approximately $10.0 million preceded a sharp decline. Subsequent governance and pipeline news, including a CFO appointment on January 5, 2026 and multiple MTX240 licensing announcements in February 2026, generally saw positive price reactions. The March 9, 2026 advocacy grant and Phase 3 eRapa update also coincided with a gain. The current ADR ratio change follows this sequence of capital and listing-related steps.

american depositary receipts financial
"announces a ratio change on its American Depositary Receipts (“ADR”) from one (1) ADR"
A certificate traded on U.S. markets that represents ownership of shares in a foreign company, letting U.S. investors buy and sell that company as if it were listed domestically. Think of it as a local voucher for a foreign product: it makes price quotes in dollars, trades on familiar exchanges, and brings differences in liquidity, fees and legal protections that can affect returns and risk compared with buying the underlying foreign shares directly.
adr financial
"ratio change on its American Depositary Receipts (“ADR”) from one (1) ADR representing"
An American Depositary Receipt (ADR) is a financial certificate that lets investors buy shares of a foreign company through U.S. stock markets, similar to buying a local wrapper that represents the underlying foreign shares. ADRs matter because they make investing in overseas companies easier and more liquid by trading in U.S. dollars and under U.S. market rules, while still carrying currency, regulatory, and country-specific risks that can affect share value.
cusip financial
"receive one (1) new ADR (New CUSIP: 59564R872) for every five (5) old ADRs"
A CUSIP is a nine-character alphanumeric code that uniquely identifies a U.S. or Canadian financial security—such as a stock, bond, or fund share—like a Social Security number for an investment. It matters to investors because brokers, exchanges and record-keepers use the CUSIP to match trades, track ownership, settle transactions and pull accurate records, reducing errors and ensuring money and securities go to the right place.
nasdaq financial
"aimed to bring the price of the Company’s ADRs into compliance with the Nasdaq $1.00 minimum"
The Nasdaq is a stock exchange where many companies' shares are bought and sold, functioning much like a marketplace for investments. It matters to investors because it provides a platform to buy and sell ownership stakes in companies, helping them track the value of those companies and make informed decisions. As one of the largest and most technology-focused markets, it also reflects trends and developments in the business world.
minimum bid price financial
"compliance with the Nasdaq $1.00 minimum bid price per share requirement"
The minimum bid price is the lowest share price that a market, regulator, or specific offering will accept for a trade, listing, or auction—think of it as a reserve or floor that a stock must meet to qualify for certain actions. It matters to investors because falling below that floor can limit trading options, trigger compliance measures or delisting risks, and affect liquidity and the perceived value of a holding, much like a reserve price in an auction sets the baseline for a sale.

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.
