PARIS (Reuters) - French engineering group Alstom (ALSO.PA) said on Wednesday it would launch a share buy-back program worth 3.2 billion euros ($3.5 billion) on Dec. 23.
Alstom said the program would concern as many as 91.5 million shares or 29.5 percent of its shareholder capital, at 35 euros a share.
Shares in Alstom closed up 4.12 percent at 30.99 euros before the announcement was made.
The company said the buy-back would be submitted for approval at a shareholder meeting on Dec.18.
French industrial conglomerate Bouygues (BOUY.PA) would take part in the share buy-back program and keep its stake unchanged at 29.2 percent, Alstom said.
Alstom completed a 12.35 billion euro ($13.41 billion) sale of its energy business to U.S. General Electric (GE.N) on Monday, helping it refocus on its transport business.
