What types of companies issue ADSs?

Non-U.S. companies seeking to raise capital in the U.S. or increase their base of U.S. investors may seek to issue ADSs.

What is an ADS/Ordinary Share ratio?

This ratio reflects the number of ordinary shares that correspond to 1 ADS. In the case of Motif Bio, each ADS represents 20 ordinary shares.

How can I buy an ADS?

You can buy an ADS through a broker, just as you would any other U.S. securities.

Can UK shareholders invest in Motif Bio’s ADSs?

Yes, it is possible for UK shareholders to purchase ADSs directly or to convert their UK ordinary shares into ADSs. We would advise that UK shareholders seek advice from their broker and/or tax adviser.

Are holders of ADSs entitled to vote at Motif Bio’s annual general meeting?

Holders of ADSs may authorise The Bank of New York Mellon, Motif Bio’s Depositary, to act as a proxy in exercising voting rights according to the number of ordinary shares represented by their respective ADSs.

When I want to buy Motif Bio’s securities, how does it work in practice?

When you instruct your broker to buy ordinary shares on your behalf, your broker will have the option of buying AIM listed ordinary shares, or buying NASDAQ listed ADSs and asking The Bank of New York Mellon, as depositary to convert them into ordinary shares. Conversely, when you wish to sell your position, your broker will either sell the ordinary shares you hold on AIM, or otherwise, may sell them to the Bank of New York Mellon who will then sell them as ADSs on the NASDAQ market. In any event, this would be a seamless process for shareholders. Shareholders will not need to be concerned with which market their shares are purchased from or sold into; brokers will simply sell in the market where there is the most liquidity. If ordinary shares are held in certificated form, shareholders will be required to deliver a share certificate that will be deposited with The Bank of New York Mellon prior to executing a sale on NASDAQ.

What does a depository bank do?

A depositary is a bank that facilitates cross-border trading of an issuer’s shares. Among other things, depositary banks provide ADS issuance and cancellation services, and associated stock transfer services such as maintaining the register of holders, distributing dividends in U.S. dollars, providing annual meeting services and executing corporate actions. So, in practice, the depositary bank maintains records of the holders of ADSs and manages the flow of shares between the two separate markets, essentially converting Ordinary Shares into ADSs when there is demand in the U.S., and converting ADSs back into Ordinary Shares when there is demand for the Ordinary Shares. This service creates a liquidity between the two markets that will help minimize any price differential between the two markets.
