"2020 was an extraordinary year ... We are coming out of 2020 with a stronger balance sheet, ready to accelerate our strategy and make the future of energy".

Those were the words of Royal Dutch Shell CEO Ben van Beurden as the Anglo-Dutch energy giant announced a 71 percent fall in profits for the year. Although analysts caution that the figures have been skewed by writedowns and energy firms have been forced to reassess their asset values amid the COVID-19 pandemic and a decreasing consumer appetite for fossil fuels.

The semiconductor shortage is continuing to cause problems for all the major auto firms. Japan's Mazda and General Motors have become the latest to warn of fewer cars coming off the production line this month. 

Meanwhile, regulators in London and Brussels are to investigate the planned takeover of the UK chip designer Arm by Silicon Valley software giant Nvidia, as demand for its products booms globally.

For those still slightly baffled by the recent events on Wall Street, and what exactly activist shareholder groups have done to knock millions off the value of top hedge funds, watch our video below to find out. 

And with all eyes now on the energy majors and how they intend to create a new future away from oil and gas, the latest figures are out on fossil fuel consumption in the EU. They show it could be some time yet before some member state reforms their gas-guzzling ways.

Oil giant Royal Dutch Shell says full-year profit dropped 71 percent to $4.8 billion, from $16.5 billion last year, as the COVID-19 pandemic accelerated the already faltering demand for oil and gas. Shell, which last September announced 9,000 job cuts worldwide, says that "significant uncertainty" in the energy market will continue to weigh on results.

Earlier this week, rivals BP and Exxon Mobil both posted similar losses, while revealing plans to refocus their production models towards greener and more renewable energy sources. In a sign of possible consolidation in the troubled sector, it has emerged that U.S. oil giants Exxon and Chevron held preliminary talks last year on a possible merger. 

Revenues at the online marketplace eBay rose to $2.9 billion for the three months to the end of December 2020, ahead of analysts' expectations. Gross trading volumes jumped by a fifth to $26.6 billion, compared with the same period in 2019, as people turned to internet shopping in lockdown. CEO Jamie Iannone said the firm "will be stronger coming out of the pandemic than going in."

General Motors says it will cut production entirely at three of its U.S. factories next week, blaming the global semiconductor chip shortage. The car giant added that a factory in the Republic of Korea would also run at half capacity. 

Mazda has also said it expects the chip shortage to affect its vehicle production from this month. The Japanese auto maker says it believes the ongoing squeeze on supplies will affect around 7,000 vehicles globally from this month. CEO Akira Marumoto has described the situation as "extremely fluid." Several other auto makers have cut production due to chip shortages including Volkswagen, Ford, Toyota and Nissan.

Shares in the software multinational Qualcomm have fallen after first-quarter revenues missed expectations. In the three months to the end of December, revenues were $8.23 billion, while sales rose year on year by 63 percent, propelled by chip demand for 5G smartphones. CEO Steve Mollenkopf has blamed supply constraints for the outlook.  

EU and UK regulators are to investigate the planned $40 billion takeover by Silicon Valley software firm Nvidia of the UK chip designer Arm. Officials say serious scrutiny of the deal is warranted given the popularity of Arm's products with smartphone makers such as Apple and Samsung. The investigation may take 18 months.  

Deutsche Bank made a net profit of $135 million last year, above analysts' expectations and its first profit since 2014. Revenues for the year rose 32 percent to $11 billion partly due to a jump in trading at the investment banking division. Deutsche Bank has been undergoing a sweeping cost-cutting exercise aimed at reducing the less profitable lines of its global operation and refocusing on its core European business.

Chinese home appliance giant Midea is buying a 43 percent stake in the health equipment maker Beijing Wandong Medical. The $355 million deal gives Midea a 24 percent controlling stake in the firm, best known for producing imaging equipment, diagnostic services and X-ray tube production.

Shares in the Chinese video-sharing mobile app Kuaishou Technology have surged ahead of its stock market debut in Hong Kong on Friday. The Tencent Holdings-backed short video start-up, seen as the main rival to ByteDance, has seen its shares rise 181 percent in grey market trading, putting it on course to become the second highest billion-dollar flotation on record in Hong Kong.

Shares in the Berlin-based online used-car dealer Auto1 Group SE have surged by 49 percent on their market debut, rising to almost $63 each by mid-morning. Auto1, which is backed by Japanese tech financier Softbank, reported revenues of $4.2 billion on the sale of more than 600,000 vehicles in 2019. Auto1 Group has benefited during the pandemic from the lockdown of bricks-and-mortar car showrooms according to analysts.  

American Airlines says 13,000 employees are at risk of being furloughed when a U.S. aid package for airline workers runs out at the start of April. The carrier is blaming slow vaccine roll-outs and new restrictions on international travel for the continuing slump in demand for travel. Aviation unions are seeking an extra $15 billion in payroll assistance to protect jobs through the summer. A memo to staff management at American stated: "Five weeks into 2021 and, unfortunately, we find ourselves in a situation similar to much of 2020." 

The CEO of social media platform Parler, John Matze, claims he has been fired by the board of the firm. Parler came to prominence during the Capitol Hill protests early last month when it became the preferred social network among supporters of former U.S. president Donald Trump, briefly becoming the most downloaded app in the U.S.. In a memo to staff, Matze claimed he had met "constant resistance to my product vision, my strong belief in free speech and my view of how the Parler site should be managed."

WATCH: Individual investors known as "retail investors" disrupted the stock market recently when they bought shares en masse in the company GameStop. That move sent share prices rocketing by more than 1,000 percent and cost hedge funds millions of dollars, as they had expected their value to drop before they bought them back at a profit. Could the GameStop controversy now become a common trend? We explain what it all means...

Peer-reviewed research in the British medical journal The Lancet says the Russian jab Sputnik V is 92 percent effective in fighting COVID-19. Nicaragua has become the latest country to approve the vaccine, with Hungary the first EU country to give it the green light. CGTN Europe was joined by Kirill Dmitriev, CEO of the Russian Direct Investment Fund, which financed the jab's development, and asked him how significant the release of the Sputnik Phase 3 trial results has been.

I do think it's very important and we got major support not only from the LANCET, but also from many scientists, including from the US, Europe, China, who commented very positively on the vaccine. And it's very important that not only the vaccine is more than 90 percent effective against COVID 19 and 100 percent effective against severe cases, but also it is very affordable and it can also be stored at plus two. plus eight temperatures versus minus 70 centigrade required for some of the vaccines. We call it a humankind vaccine on being safe, efficient, affordable and easy to distribute. 

Prior to this international seal of approval, how do you think the rest of the world viewed Russia's COVID-19 vaccine development and trials? 

I think the world was divided, so a majority of the world was very positive. But, of course, we had some criticism from the U.S., from Europe, from Britain and lots of disbelief about the Russian vaccine. 

But what was good for us is that most of the countries view Russian action very positively. We saw 75 percent brand recognition of Sputnik, and Sputnik listed as one of the first two top vaccines in most of the countries. But we definitely feel vindicated versus the position of some of the people in the U.S., UK and Europe with The Lancet article, because it did show that we are one of the three most efficient vaccines in the world.

Are you confident that the Sputnik jab can be produced and exported in huge volumes?

You mentioned the figure of 700 million people that we expect to vaccinate by the end of the year and, indeed, we have some good facilities for production in Russia and we are increasing them - there will be new factories coming online in the next couple of weeks that we will announce. But we also built major partnerships to produce vaccines in China, Brazil, Korea, Russia, India and we are sharing our technology with those producers to produce it internationally. And we mentioned that starting from May, we could supply up to 50 million people doses in Q2, Q3 of this year. 

How can using one shot of both the AstraZeneca and Sputnik jabs trigger a better immune response?

This is at the core of Sputnik – we use two different components for two different shots and the logic is that after you inject the first component the body starts attacking it. So next time you inject the same component it's less efficient, because of the immunity being built on this component. So when you change a component, you basically trick the body system to not attack the delivery mechanism. Then the second shot becomes much more effective. And Sputnik is the only vaccine in the world that currently uses two components for different shots.

And finally, just as Shell reveals the extent of losses it made in its core business last year, the latest figures show the extent to which the EU remains a gas-guzzling continent. While the long-term use of fossil fuels is falling, two-thirds of the bloc's energy consumption came from non-renewables in 2019, with big swings between member states.
