Frontline Ltd. and rival Euronav have signed an all-stock merger deal to create a market-leading oil tanker group with 146 vessels, including 68 Very Large Crude Carriers (VLCCs), the companies said on July 11.

The firms, which expect the merged company to have a market capitalization of more than $4 billion and to generate synergies of at least $60 million a year, first announced their intention to merge on Apr. 7.

Shares in Oslo-listed Frontline, the smaller of the two but after which the combined group is to be named after, will be exchanged into Brussels-listed Euronav shares at a ratio of 1.45:1.

The combined company will be held roughly 55% by existing Euronav shareholders and 45% by existing Frontline shareholders, assuming all Euronav shares are tendered in the tender offer.

Frontline and Famatown Finance Ltd. currently already own 18.8% of the total outstanding shares in Euronav, it said.
