Private equity firm Vista Equity Partners has struck a deal to acquire D+H, a Canadian financial technology provider, with an eye to merging it with UK-based Misys to create a financial software company with $2.2 billion in revenues.

US-based Vista said in a statement today that it will pay C$25.50 per share in cash for D+H, including the assumption of debt, in a deal that values the Toronto-listed firm at 4.8 billion Canadian dollars.
