Samsung shares fell 2 percent on Wednesday after the technology giant said stronger-than-expected demand for its new Galaxy Note 7 meant it had to push back the release date in some markets.
"We appreciate the strong demand and positive response to the Galaxy Note7 from consumers across the globe. As pre-order results for the Galaxy Note7 have far exceeded our estimates, its release date in some markets has been adjusted," Samsung said in a statement emailed to CNBC.
"We look forward to meeting consumers' demand as early as possible," the company added without saying which markets delays could be possible in.
In Europe, prior to the start of the pre-order offer on August 16, consumer registrations for the Note 7 on Samsung's digital channels had exceeded that of the Galaxy S7 and S7 Edge, the company said. As a result, Samsung said the launch of the device across the region is "being phased". Countries across Europe will launch on September 2, 9 or 16, with the U.K., France and Germany the first markets to launch on September 2.
The South Korean electronics titan unveiled the 5.7-inch Note 7 earlier this month with analysts hailing it as one of the best devices on the market. Samsung's latest statement suggests that the device is selling well, something that can help drive further growth in its mobile division.
But fears that a supply shortage could lead to consumer dissatisfaction and ultimately them turning to other devices from the likes of Apple or Huawei, sent shares of Samsung sliding. It's worth noting that Samsung shares recently hit an all-time high and the move could also be some investors taking profit.
The company did not say what was causing the supply constraint. A spokesperson said it was not to do with the slightly curved screen on the Note 7, a problem it suffered when it launched the Samsung S6 Edge last year.
