Domino’s Pizza is buying out its Japanese joint venture partner Bain Capital’s minority stake for $42 million.

Domino’s, which in May announced Bain’s intention to exit, on Monday said it would pay less than the $46.4 million it set aside for the deal in its full-year accounts.

The purchase will be funded by a combination of cash and existing debt facilities, and is expected to be completed by Friday.

Domino’s said the transaction will be earnings per share accretive in the current financial year, which started on July 3.

The deal is the second in less than a week for Domino’s.

Last week, the company continued its European expansion with the 32 million euro (A$48.1 million) acquisition of German chain Hallo Pizza.
