public offering financial

"Participation in the public offering undertaken by Star Bulk Carriers Corp in Greece"

A public offering is when a company sells shares to the general public through the stock market, either by issuing new shares to raise cash or by letting existing owners sell their stakes. Think of it like a business opening its doors to many new owners at once: it can bring in money for growth but also increases the number of shares available, which can change the stock price and dilute existing ownership — key factors investors watch closely.

dual listing financial

"following its dual listing on Euronext Athens"

A dual listing is when a company makes the same shares available on two different stock exchanges, often in different countries, so investors can buy and sell the same ownership stake in more than one market—like a shop opening branches in two cities that sell the same product. It matters to investors because it can widen the pool of buyers, make shares easier to trade, expose the stock to different currencies and rules, and create price differences or arbitrage opportunities that affect returns and risk.

indirect financial

"These shares are held by 3 corporations in which the reporting person holds 100%"
