Sunrise, the second largest of three operators in Switzerland, has annnounced the launch of its IPO and set a price range of between CHF58 and CHF78 per share, giving it an implied market value of up to CHF3.3 billion ($6.76 billion).

The first day of trading on the stock exchange will be on or before 6 February in what could be the country’s biggest flotation since 2006.

Earlier this month, when the IPO plan was first revealed, the company had said that proceeds, which it predicted would be around $1.3 billion, would allow it to “substantially strengthen its balance sheet” and reduce the cost of debt.

It added that the IPO would “support its corporate strategy of investing in state-of-the-art integrated mobile and fixed network technology.”

Although there are no real signs of a deal, the IPO could also pave the way for Sunrise to merge with Orange Switzerland in order to better compete with top player Swisscom, according to speculation.

Sunrise also clarified that the Swiss National Bank’s recent abandonment of its franc cap will not impact its IPO plans, given that the company’s revenues are earned entirely in francs while most of its debt is in euros.

Sunrise, owned by private equity firm CVC, has 2.66 million mobile connections (Q4, 2014), according to GSMA Intelligence.
