share buy-back program financial

"Materialise reports on the progress of its share buy-back program announced"

A share buy-back program is when a company uses cash (or borrows) to buy its own stock from the open market or shareholders, reducing the number of shares available to investors. For investors this matters because fewer shares can raise earnings per share and often support the stock price, while signaling that management believes the shares are a good use of cash—similar to a retailer buying back coupons so each remaining coupon becomes relatively more valuable.

discretionary mandate financial

"Materialise has granted a discretionary mandate to an independent financial"

central order book market

"43,345 shares were repurchased through the central order book of the following"

treasury shares financial

"Materialise currently holds 1,323,060 of its own shares"

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.
