Premarket London: Vodafone Signs up AWS in 5G; Rio Hit by Violence

Investing.com -- Here is a summary of the most important regulatory news releases from the London Stock Exchange on Wednesday, 4th December. Please refresh for updates.

Telecoms giant Vodafone (LON:VOD) said it has signed an agreement with Amazon (NASDAQ:AMZN) Web Services to provide AWS Wavelength in Europe on its 5G networks.

AWS Wavelength embeds AWS compute and storage services at the edge of telecommunications providers' 5G networks, enabling developers to serve end users with single-digit millisecond latencies over the 5G network, Vodafone (LON:VOD) said.

"Faster speeds and lower latencies have the potential to revolutionize how our customers do business,” said Vodafone (LON:VOD) business head Vinod Kumar.

Rising violence towards its employees has forced Rio Tinto (LON:RIO) to curtail operations at Richards Bay Minerals in South Africa, forcing it to cut lower its forecast for titanium dioxide slag production this year.

It has halted all mining operations and is operating the smelters at a reduced level, “with a minimum number of employees now on site.” Construction of the Zulti South project has also been temporarily paused.

Rio said it now expects TiO2 slag production to be at the bottom end of the 1.2-1.4 million ton guidance range for this year.

Grocery store chain WM Morrison (LON:MRW) said it’s moving chief financial officer Trevor Strain to the chief operating officer’s position.

Michael Gleeson, who has been trading director responsible for ambient grocery, frozen, dairy, fuel and services since January 2017, will succeed Strain as CFO.

Builders supplies group Ferguson (LON:FERG) said it expects to buy back up to $64 million in stock in the first half of next year, as part of its ongoing buyback program.

It has instructed JPMorgan (NYSE:JPM) Securities accordingly.
