6:38 pm: Tesla adds 'health epidemics' as a business risk

Tesla's latest annual 10-K filing revealed a new risk to its business: "health epidemics." In the filing, the electric automaker said its gigafactory in Shanghai was closed for a brief time as the coronavirus spread in China. "It is unknown whether and how global supply chains, particularly for automotive parts, may be affected if such an epidemic persists for an extended period of time," the company said. "We may incur expenses or delays relating to such events outside of our control, which could have a material adverse impact on our business, operating results and financial condition." At the end of January, CEO Elon Musk had downplayed the risk, but two more weeks of coronavirus feared seem to have changed Tesla's mind. —Kolodny

6:15 pm: United scales back Barcelona service after coronavirus upends Mobile World Congress

United Airlines is scaling back its service to Barcelona after the Mobile World Congress, the world's largest telecommunications show, was called off because of coronavirus concerns. Organizers of the event called it "impossible" to hold because of the outbreak, which has now sickened more than 60,000 people, mostly in China. United had ramped up service ahead of the event, which last year drew around 100,000 people, as part of a trend among U.S. airlines to target high-paying travelers going to major conferences like MWC, the Consumer Electronics Show, and other events like political conventions and sporting events. United had added four round-trips between San Francisco and Barcelona and it will cancel two of them — leaving San Francisco on Feb. 26 and Feb. 27 and use smaller aircraft for the others. It will also use smaller planes for Newark-Barcelona flights than it planned. — Josephs

5:55 pm: Royal Caribbean warns cruise cancellations in Asia to shave 2020 profit by 65 cents

Royal Caribbean has had to cancel 18 sailings in Southeast Asia and modify itineraries for several other cruises. The result: a big blow the bottom line. The company expects 65 cents will be shaved off its 2020 earnings per share. If the outbreak continues and it's forced to cancel all of its trips in the region through the end of April, profits would take an additional hit of 55 cents per share. The company added it's in regular conversation with the CDC, the WHO and other health authorities and has put in place measures to protect passengers and crew. Among those steps is denying the boarding of people who have travelled to and from mainland China or Hong Kong in the past 15 days. "It is important that every organization acts responsibly, and we have already taken aggressive steps to minimize risk through boarding restrictions and itinerary changes," said Richard D. Fain, chairman and CEO. Royal Caribbean shares were down more than 1% in extended trading. Shares have fallen nearly 15% since the start of the year. — Cheddar Berk

Yeti's preparation for the Dec. 15 tariffs that never happened has helped the company avoid major problems from the coronavirus, CEO Matt Reintjes told CNBC.

The levies were ultimately canceled, but Yeti still benefited from its decision-making.

3:00 pm: Emerging market debt shrugging off fears that the outbreak could hurt economies

Emerging market debt, as an asset class, has been spared a big impact from the coronavirus so far. Fear the virus will hurt the global economy has driven Treasury yields lower, and the easy money policies of the world's central banks have pushed yields lower around the globe, so the hunt for yield has become ever more challenging. Emerging market debt is a "least bad" choice, in the view of Brian Funk head of credit research at MetLife Investment Management. "It's offering value on a risk-adjusted basis at this stage in the cycle." According to Bank of America, flows into emerging market debt funds as of last week were running at a record clip, aside from a small outflow the week earlier. — Domm

1:34 pm: Airbnb suspends bookings in parts of China

Airbnb is suspending bookings in Beijing until May as the rapid spread of coronavirus prompts new local restrictions for the home-sharing giant.

High-end fashion retailer Ralph Lauren said it has closed about two-thirds of its stores in mainland China, saying that it expects a larger impact to its business in China and other parts of Asia than previously anticipated.

It said its fourth-quarter fiscal 2020 sales are expected to be hit by $55 million to $70 million, with operating income in Asia lowered by $35 million to $45 million. And it could become worse if the coronavirus outbreak widens. Earlier this month, Ralph Lauren had told analysts it had closed about half of its roughly 110 locations in China. It said China represents about 4% of its overall business. —Thomas
