MediaTek has reported November consolidated revenues fell 10.4% sequentially to a nine-month low of NT$18.67 billion (US$604.2 million). Consolidated sales for the first 11 months of 2018 slipped 1.3% from a year earlier to NT$216.67 billion.

MediaTek's revenues will have to rebound to NT$19.5 billion in December in order to have its revenues for the fourth quarter come within the guidance given previously between NT$59 billion and NT$64 billion.

Market watchers expect MediaTek to meet its sales guidance for the fourth quarter of a 4-12% sequential decline. The chip firm will likely see its revenues register flat sequential growth in the first quarter of 2019 followed by a 20% increase in the second quarter.

MediaTek CEO Rick Tsai was quoted in previous reports saying the company expects to post a slight decrease in revenues for 2018 when combined shipments of its smartphone- and tablet-use SoCs will register a mild drop. However, gross margin will improve in 2018 thanks to the roll-outs of new mobile SoC products and the company's efforts for diversification.

MediaTek continues to enhance its AI-capable SoC lineup and plans to roll out its 5G modem chip in the first half of 2019, according to Tsai, who is optimistic about the competitiveness of the company's mobile SoC solutions next year.
