MediaTek has posted its weakest monthly revenues in six months on seasonal factors.

MediaTek generated consolidated revenues of NT$23.81 billion (US$755.81 million) in October 2016, down 14.1% sequentially but up 7.1% on year.

MediaTek expects to post revenues of between NT$66.6 billion and NT$72.9 billion in the fourth quarter, down 7-15% on quarter. Shipments would be affected by foundries' continued tight supply of 28nm chips, as well as a slowdown in customer demand, the company said at a recent investors meeting.

MediaTek disclosed its overall smartphone and tablet chip shipments would decrease to 135-145 million units in the fourth quarter from 145-155 million units in the third. Gross margin would be kept in the range of 33.5-36.5% in the fourth quarter and the following several quarters due to continued-intense competition in the smartphone-IC market, the company said previously.

MediaTek posted revenues of NT$78.4 billion in the third quarter of 2016, up 8.1% sequentially and 37.6% on year, while gross margin stayed unchanged from the previous quarter but fell 7.5pp from a year earlier to 35.2%.
