Form 3 regulatory

"Radiopharm Theranostics Ltd filed an initial Form 3 for Chief Financial Officer"

Form 3 is the initial public filing that officers, directors and large shareholders must submit to report their ownership of a company’s securities when they become insiders. It acts like an opening inventory sheet that gives investors a starting point to see who holds significant stakes and to spot later trades or potential conflicts of interest, helping assess insider confidence and transparency.

Ordinary Shares financial

"He directly holds 26,357 Ordinary Shares and an option to buy"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

Option (right to buy) financial

"The CFO holds an Option (right to buy) covering 17,857 Ordinary Shares"

exercise price financial

"an option to buy 17,857 Ordinary Shares at an exercise price of $0.2000 per share"

The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
