major shareholder notification regulatory

"it has received the following major shareholder notification pursuant to Section 38"

private placement financial

"issuance of 35,095,758 new shares as part of a private placement in Cadeler"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.

dilution financial

"direct shareholding in Cadeler has been reduced due to dilution resulting from the issuance"

Dilution occurs when a company issues additional shares, increasing the total number of shares outstanding. This can reduce the ownership percentage and voting power of existing shareholders, similar to slicing a pie into more pieces—each piece becomes smaller. For investors, dilution can mean a reduced stake in the company and potentially lower earnings per share, affecting the value of their investment.
