At the Market financial

"in connection with its "At the Market" or "ATM" sales agreement with Cantor Fitzgerald & Co"

“At the market” describes a method companies use to sell newly issued shares directly into the open market at whatever the current trading price is, usually through a broker who places shares in small amounts over time. Investors care because it can reduce each existing shareholder’s ownership percentage and increase the number of shares outstanding, while giving the company a flexible, quick way to raise cash — like adding single seats to a train instead of buying a whole new carriage.

ATM Sales Agreement financial

"in connection with its "At the Market" or "ATM" sales agreement with Cantor Fitzgerald & Co"

An ATM sales agreement is a standing arrangement that lets a company sell its shares directly into the open market at prevailing prices, often through a broker, instead of selling a large block all at once. Investors care because it gives the company a flexible, on-demand way to raise cash but can slowly increase the number of shares outstanding and put downward pressure on the stock price—think of it like drip-feeding new supply into a marketplace.

block admission regulatory

"Utilisation of the block admission in respect of ATM Sales Agreement"

depositary interests financial

"4,000,000 depositary interests representing the same number of common shares"

Depositary interests are certificates or electronic receipts that represent ownership of shares in a foreign company held by a local custodian, letting investors buy and sell those shares on their home exchange without directly holding the underlying foreign stock. Think of them like a warehouse receipt for goods stored overseas: they make trading simpler and often avoid the need to deal with foreign paperwork, currency or settlement systems. Investors use them to access foreign companies more easily, but rights such as voting and dividend timing can differ from holding the original shares.
