PARIS--Vivendi SA (VIV.FR) Thursday posted a drop in net profit for the first quarter of the year as the group cements its refashioning into a smaller media company.

Vivendi said net profit fell 19% to 431 million euros ($591 million) from EUR534 million in the same period last year, dragged down by an exceptional tax charge linked to the pending sale of its French phone unit SFR.

Vivendi reported its first quarterly results excluding SFR, a business that contributed to around half of its sales and profits prior to the agreement to sell it to Patrick Drahi's holding firm Altice SA last month.

Excluding SFR, sales fell 3.7% to EUR2.72 billion from a pro-forma of EUR2.83 billion last year as growth at its Canal Plus pay TV unit couldn't offset a decline at its Universal Music group and Brazilian telecom company GVT, where the weaker local currency weighed on sales.

Vivendi has been selling a flurry of assets, including most of its stake in videogame maker Activision Blizzard Inc., and SFR and Maroc Telecom, as it seeks to pay down debt and become a smaller-based firm focusing on media and content activities.

Vivendi is set to lay out its new media strategy later in the year after replacing its current Chairman Jean-Rene Fourtou with French industrialist Vincent Bollore.
