French video game titan Ubisoft saw its shares plunge 23 percent on Wednesday after announcing that delays to two new titles would cause a significant operating loss this year.
The adventure game "Watch Dogs" was due to hit the market next month but will instead be released in spring 2014 to give game makers more time to perfect it.
Another game, "The Crew", will come out in the summer.
The company said it now expected a 2013-2014 operating loss of 40-70 million euros ($54-95 million).
It also reduced its sales figure for this year by nearly a third, from an upper estimate of 1.45 billion euros to 1.05 billion euros ($1.4 billion).
