5 terms

convertible bonds financial

"following the issuance of 1,031,323 new shares ... held by the holder of the convertible bonds issued"

A convertible bond is a loan a company issues that pays regular interest and can be exchanged for a fixed number of the company’s shares under specified terms. It matters to investors because it combines the steady income and lower downside risk of a bond with the upside potential of owning stock—like holding a ticket that can be cashed for equity if the share price rises—affecting returns, risk, and shareholder dilution.

subscription rights financial

"Number of rights to subscribe to securities carrying voting rights not yet issued... all granted subscription rights"

Subscription rights are short-term privileges given to existing shareholders to buy additional new shares before the general public, typically at a set price and in proportion to their current holdings. Think of it as getting a coupon for first dibs on extra slices of a pizza so your share of the pie doesn’t shrink; exercising them can be a cheaper way to maintain your ownership and voting power, while ignoring them can reduce your stake and potential future earnings.

Relevant Share Settlement Price financial

"at a conversion price of EUR 2.18 (rounded) per share (EUR 2.18 (rounded) being the “Relevant Share Settlement Price”"

The relevant share settlement price is the specific per‑share price chosen to calculate how much cash or consideration is paid when shares are transferred or cancelled as part of corporate actions (for example takeovers, buybacks, option exercises or compulsory acquisitions). It matters to investors because it determines the actual money they receive or must pay and can affect the perceived fairness and tax outcome — think of it as the bill or receipt price set for a particular transaction, which may be a single day’s closing price or an averaged price over a defined period.

Interest Payment Date financial

"the most recent “Interest Payment Date”/“Scheduled Amortisation Payment Date” in relation to the convertible bonds"

The interest payment date is the scheduled day when a borrower pays the agreed interest on a bond, loan, or other debt instrument to investors who hold that debt. It matters because it determines when investors receive income, affects cash-flow planning and yield calculations, and signals whether payments are being made on time—missing a payment can reduce income and raise concerns about credit risk, much like a missed paycheck raises red flags for an employee.

Scheduled Amortisation Payment Date financial

"the most recent “Interest Payment Date”/“Scheduled Amortisation Payment Date” in relation to the convertible bonds"

The scheduled amortisation payment date is the specific day when a borrower is required to make a planned principal repayment on a loan or debt instrument according to its repayment schedule. For investors, these dates matter because they determine when capital is returned, affect expected cash flows and yield, and signal when credit risk or liquidity needs may change—much like the fixed dates you make mortgage payments that reduce what you owe over time.
