sukuk financial

"lease certificates (sukuk)"

Sukuk are tradable financial certificates that raise capital by giving investors an ownership share in an underlying tangible asset, a pool of assets, a project, or an income stream, structured to comply with Islamic law (Sharia). Instead of paying interest, sukuk deliver returns derived from the actual cash flow of the underlying asset—commonly through rent, profit-sharing, or sale proceeds—and holders are treated as owners of that asset or its income rights rather than as unsecured creditors. Structures and exact rights vary (for example, ijarah/lease, mudaraba/partnership, musharaka/joint venture), so legal claims and repayment mechanics depend on the specific sukuk contract and local law.

asset leasing company financial

"through an asset leasing company based in Türkiye"

private placement financial

"as a private placement"

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.
