Luxury goods maker Richemont today offered to pay up to 2.8 billion (US$3.42 billion) to buy the shares in Yoox Net-A-Porter (YNAP) that it does not already own in a deal aimed at boosting the Swiss company’s online presence.

The offer, for 38 per share for the 75 per cent of shares that Richemont does not own, represents an almost 26 per cent premium to YNAP’s closing price on Friday, according to Thomson Reuters data.

The deal values Italy’s YNAP at about 3.6 billion, according to Reuters data.

In 2015, Yoox bought Richemont’s Net-A-Porter unit in a transaction that gave the Swiss company a 25 per cent voting stake and put the Italian company’s management in charge.

Now seeking to take control, Richemont chairman Johann Rupert said he sees a “meaningful opportunity” to strengthen YNAP’s position in luxury e-commerce, including by expanding to new markets and adding to the product range.

“We are very pleased with the results achieved by Yoox Net-A-Porter Group’s management team, led by Federico Marchetti, and we intend to support them to execute their strategy and further accelerate the growth of the business,” Rupert said.

Richemont, the owner of luxury brands Cartier, IWC and Dunhill, announced the deal after the Italian company waived provisions stemming from the 2015 transaction that would have prevented Richemont from boosting its stake.

YNAP’s shares would be delisted from the Milan exchange, according to terms of the deal.​
