Amsterdam-based stock exchange operator Euronext has launched its final tender offer for Norwegian rival Oslo Bors.

Euronext offered to pay $16.96 per share of Oslo Bors, valuing it at 6.24 billion Norwegian crowns ($730 million).

The offer comes after Oslo Bors’ board said that it received alternative bids and would issue a recommendation by late February.

In late December, Euronext said that it will launch a tender offer for Oslo Bors, representing more than 50 percent of Oslo Bors’ shares.
